Introduction: In this study, researchers collaborate with children from a low socioeconomic neighbourhood in Amsterdam in developing, implementing and evaluating interventions targeting their health behaviours. This Youth Participatory Action Research project focuses on the promotion of physical activity and healthy dietary behaviour., Methods and Analysis: This study is a controlled trial using participatory methods to develop interventions together with children aged 9-12 years. At four primary schools in a low socioeconomic neighbourhood in Amsterdam, an 'Action Team' is installed: a group of six to eight children who actively participate as co-researchers in developing, implementing and evaluating interventions. An academic researcher facilitates the participatory process. Four control schools, also located in low socioeconomic areas in and around Amsterdam, continue with their regular curriculum and do not participate in the participatory process. For the effect evaluation, physical activity and sedentary behaviour are assessed using accelerometers and self-reporting; dietary behaviour using self-reporting and motor fitness (strength, flexibility, coordination, speed and endurance) using the motor performance fitness test. Effectiveness of the interventions is evaluated by multilevel regression analysis. The process of co-creating interventions and the implemented interventions is continually evaluated during meetings of the Action Teams and with children participating in the interventions. Empowerment of children is evaluated during focus groups. Summaries and transcripts of meetings are coded and analysed to enrich children's findings., Ethics and Dissemination: The Medical Ethics Committee of the VU Medical Center approved the study protocol (2016.366)., Trial Registration Number: TC=6604., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Background: Health promoting behaviors are among the determinants of health. Hemodialysis causes significant changes in the lives of patients and affects their health promoting behaviors. Accordingly, this study aimed at investigating the effect of exercise during hemodialysis on health promotion behaviors in patients undergoing hemodialysis., Methods: This study was a two-stage (before and after) clinical trial. The sample of the study consisted of 60 hemodialysis patients in two hospitals in Isfahan who were selected randomly and divided into two groups of control and intervention using random allocation method. A 8-week exercise program by stationary bicycles (Mini-bike) was designed for the intervention group, while the control group underwent a 10-min limbering exercise for 8 weeks. Data were collected using demographic questionnaire and the Health Promoting Lifestyle Profile II (HPLP-II) questionnaire before and after the intervention and were analyzed using SPSS21 software., Results: Based on the independent t-test results, no significant difference was observed between the mean score of health promoting behaviors and its areas before the intervention (P > 0.05). However, the results of this test showed that the mean score of health promoting behaviors and its areas, except for the areas of responsibility (P = 0.052) and spirituality (P = 0.211), was significantly different between the two groups after the intervention (p < 0.05)., Conclusions: The results of this study showed that exercise with stationary bicycle during hemodialysis could promote health promoting behaviors. Thus, this exercise is recommended to be considered as part of the therapeutic protocol of these patients in hemodialysis departments., Trial Registration: The clinical trial was found to be in accordance to the ethical principles and the national norms and standards for conducting medical research in Iran.

Background: Although previous studies have revealed many factors related to mild cognitive impairment (MCI) reversion, information about reversible factors related MCI reversion is limited, impeding the development of intervention strategies. The aim of the present study was to examine whether reversible factors such as lifestyle activities are associated with MCI reversion in elderly individuals using the National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes database. A total of 396 community-living older adults (age ≥ 65 years) participated in the study. They were classified as reverters or non-reverters from mild cognitive impairment to normal cognition. We assessed lifestyle activities, potential confounding factors of cognitive decline, and reversion of mild cognitive impairment., Results: In a completed data set of 396 participants, 202 participants (51.0%) reverted from MCI to normal cognition. The reversion rate in participants for whom we imputed data was 34.3%. In the imputed group, a logistic regression model showed that the odds ratios (ORs) for reversion were significantly higher in participants who drove a car (OR 1.50, 95% confidence interval (CI) 1.41-1.60), used a map to travel to unfamiliar places (OR 1.12, 95% CI 1.06-1.18), read books or newspapers (OR 1.54, 95% CI 1.37-1.73), took cultural classes (OR 1.10, 95% CI 1.04-1.15), attended meetings in the community (OR 1.22, 95% CI 1.16-1.28), participated in hobbies or sports activities (OR 1.09, 95% CI 1.03-1.16), and engaged in fieldwork or gardening (OR 1.14, 95% CI 1.08-1.21). The imputed sample showed that non-reverters were more likely to discontinue fieldwork or gardening (11.0% vs. 6.1%) than reverters during the follow-up period., Conclusions: Specific lifestyle activities may play important roles in MCI reversion in older adults. The longitudinal data indicate that it is reasonable to recommend that individuals continue to engage in fieldwork or gardening to increase their chance of recovery from MCI.

Substantial evidence identifies mothers of children with a disability as having a higher risk for compromised health outcomes and lifestyle restrictions secondary to caring responsibilities. Healthy Mothers Healthy Families (HMHF) is an evidence informed health and empowerment group-based workshop program., Methods: HMHF features health education and lifestyle redesign content. Mixed methods evaluated the program. This paper presents a pretest-postest time series design to evaluate outcomes over 8 months., Results: Mothers reported significant change across 4 time points including participation in healthy activity (p = 0.017), depression, anxiety, stress symptoms (p = 0.017, 0.016, 0.037 respectively) and empowerment (p = 0.009)., Conclusion: Coupled with qualitative findings, these results suggest that HMHF is effective at improving health and wellbeing outcomes for mothers of children with a disability.

Objective: Unhealthy lifestyle behaviors, such as smoking, drinking, betel-quid chewing, insufficient exercise, and inadequate sleep are significantly correlated with metabolic syndrome (MetS). To further understand this relationship, this study examined the main effect of unhealthy lifestyle behaviors and their interaction on MetS by gender in young adults., Method: A cross-sectional study involving 694 young adults from a national survey was performed in which demographic characteristics, unhealthy lifestyle behaviors, anthropometric measurements, and blood chemistry panels were collected during face-to-face interviews., Results: The prevalence of MetS among young adults was 17.4% and was greater in males than females (19.0% vs. 7.8%). The unhealthy lifestyle-behavior risk factors associated with MetS included smoking (odds ratio [ OR] = 4.53) and physical activity ( OR = 0.51) among males and betel-quid chewing ( OR = 8.90) and less sleep ( OR = 0.08) among females. Significant interaction effects were observed between the abovementioned behaviors and gender for the risk of developing MetS., Conclusion: These results can guide health-care providers in reducing MetS risk by encouraging young adult males to reduce or quit cigarette smoking and maintain optimum levels of physical activity and young adult females to quit chewing betel quid and obtain appropriate amounts of sleep.

Background: Research shows that the development of cardiometabolic disease can begin early in life with risk factors accumulating over time, but less is known about protective pathways to positive health. In this study, we use prospective data to test whether childhood assets predict a greater likelihood of being in optimal cardiometabolic health by age 17., Methods: Data are from 3074 participants in the Avon Longitudinal Study of Parents and Children (mean age = 17.8). Four childhood assets were prospectively assessed via cognitive tests and parent report when children were between ages 8 and 10: strong executive functioning skills, prosocial behaviors, and low levels of internalizing and externalizing problems. Cardiometabolic health was assessed at ages 9 and 17 by using a composite dysregulation score derived from multiple biological parameters, including cholesterol, blood pressure, C-reactive protein, insulin resistance, and BMI. Associations between assets and optimal health at age 17 (ie, a dysregulation score of ≤1) were evaluated with Poisson regression models with robust error variances., Results: After controlling for covariates (including sociodemographics, correlates of cardiometabolic health, and dysregulation scores at age 9), participants with multiple assets were 1.08 to 1.27 times more likely to be in optimal cardiometabolic health at age 17 compared with those with 0 or 1 asset. Each additional asset conferred a 6% greater likelihood of optimal health over time (relative risk = 1.06 [95% confidence interval: 1.01 to 1.11])., Conclusions: Childhood assets predicted cardiometabolic health with seemingly cumulative impacts. Identifying early assets may provide novel targets for prevention and elucidate pathways to positive adult health., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

A substantial proportion of adults at healthy body mass index (BMI) are potentially at high risk for cardiovascular disease (CVD). The objective of this study is to determine if sedentary lifestyle characteristics in healthy weight adults increase their likelihood of being at high CVD risk to that of individuals who are overweight. Adults aged 40 to 79 years in the 2011 to 2016 National Health and Nutrition Examination Survey at a healthy BMI (18.5 to 24.9) and overweight BMI (25 to 29.9; unweighted n = 4,572; weighted n = 43,919,354) were analyzed. The American College of Cardiology/American Heart Association atherosclerotic CVD risk score was used to assess CVD risk. For individuals with a BMI 18.5 to 24.9, 29.6% had increased risk of a CVD event. In logistic regressions adjusted for age, race, gender, education, poverty/income ratio, insurance status, and number of visits to a healthcare provider in the past year, individuals with unhealthy sagittal abdominal diameter (odds ratio [OR] 2.44; 95% confidence interval [CI], 0.97 to 6.14), shortness of breath upon exertion (OR 1.35; 95% CI, 0.65 to 2.79), unhealthy waist circumference (OR 0.99; 95% CI, 0.60 to 1.61), and less than recommended levels of physical activity (OR 0.73; 95% CI, 0.43 to 1.23) were not significantly different than overweight adults in being at high risk for CVD events. Individuals with healthy characteristics and a BMI 18.5 to 24.9 were significantly less likely than overweight adults to be at high risk for CVD. In conclusion, the findings suggest that in individuals at a BMI 18.5 to 24.9, characteristics of a sedentary lifestyle increase the likelihood of being at high risk for CVD to that of overweight individuals., (Copyright © 2018.

Importance: Although the benefits of leisure-time physical activity (LTPA) in middle age are established, the health effects of long-term participation and changes in LTPA between adolescence and middle age have not been documented., Objective: To determine whether an association exists between LTPA life course patterns and mortality., Design, Setting, and Participants: This prospective cohort study used data from the National Institutes of Health-AARP (formerly American Association of Retired Persons) Diet and Health Study established in 1995 to 1996. Data analysis was conducted from March 2017 through February 2018. Data were analyzed for 315 059 adult AARP members living in 6 states, namely, California, Florida, Louisiana, New Jersey, North Carolina, or Pennsylvania, or 2 metropolitan areas, Atlanta, Georgia, or Detroit, Michigan., Exposures: Self-reported LTPA (hours per week) at the baseline interview for ages grouped as 15 to 18, 19 to 29, 35 to 39, and 40 to 61 years., Main Outcomes and Measures: All-cause, cardiovascular disease (CVD)-related, and cancer-related mortality records available through December 31, 2011., Results: Of 315 059 participants, 183 451 (58.2%) were men, and the participants were 50 to 71 years of age at enrollment. Ten LTPA trajectories (categorized as maintaining, increasing, and decreasing LTPA across time) were identified, and 71 377 deaths due to all causes, 22 219 deaths due to CVD, and 16 388 deaths due to cancer occurred. Compared with participants who were consistently inactive throughout adulthood, participants who maintained the highest amount of LTPA in each age period were at lower risks for all-cause, CVD-related, and cancer-related mortality. For example, compared with participants who were consistently inactive, maintaining higher amounts of LTPA was associated with lower all-cause (hazard ratio [HR], 0.64; 95% CI, 0.60-0.68), CVD-related (HR, 0.58; 95% CI, 0.53-0.64), and cancer-related (HR, 0.86; 95% CI, 0.77-0.97) mortality. Adults who were less active throughout most of the adult life course but increased LTPA in later adulthood (40-61 years of age) also had lower risk for all-cause (HR, 0.65; 95% CI, 0.62-0.68), CVD-related (HR, 0.57; 95% CI, 0.53-0.61), and cancer-related (HR, 0.84; 95% CI, 0.77-0.92) mortality., Conclusions and Relevance: Maintaining higher LTPA levels and increasing LTPA in later adulthood were associated with comparable low risk of mortality, suggesting that midlife is not too late to start physical activity. Inactive adults may be encouraged to be more active, whereas young adults who are already active may strive to maintain their activity level as they get older.

Background: While yoga can improve health-related variables and health behavior, different yoga styles and practice components appear to be associated with specific health outcomes. The aim of this study was to explore the connection between yoga use, health, and health behaviors across different yoga styles., Methods: A cross-sectional anonymous online survey (n = 1,702; 88.9% female; 93.3% German nationality; mean age 47.2 ± 10.8 years; 58.2% yoga teachers) assessed yoga practice characteristics, health-related variables and health behavior. The survey was distributed in Germany only but not limited to German participants., Results: Ashtanga yoga (15.7%), Hatha yoga (14.2%), and Sivananda yoga (22.4%) were the most commonly practiced yoga styles; participants practiced for a mean of 12.7 ± 10.0 years. Most participants had good to excellent (96.1%) overall health; 87.7% reported improved health since starting yoga. Controlling for sociodemographic and clinical factors, health-related variables were mainly associated with frequency of yoga postures practice (p < 0.05), health behaviors also with yoga philosophy study (p < 0.05). The various yoga styles were associated with specific health-related variables (p < 0.05)., Conclusion: Yoga practitioners generally have a good overall health and a healthy lifestyle. While health variables are mainly associated with practice of yoga postures, health behaviors are also associated with the study of yoga philosophy. Yoga interventions targeting prevention or health promotion should include yoga philosophy to modify health behaviors. The specific yoga style employed may also influence health outcomes., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Background: In early life, both mothers and fathers are important influences on their children's diet, active play, and obesity risk. Parents are increasingly relying on the internet and social media as a source of information on all aspects of parenting. However, little is known about the use of Web-based sources of information relevant to family lifestyle behaviors and, in particular, differences between mothers' and fathers' use and sociodemographic predictors., Objective: The objective of this study was to examine if mothers and fathers differ in their use of the internet for information on their own health and their child's health, feeding, and playing and to examine sociodemographic predictors of the use of the internet for information on these topics., Methods: We conducted a secondary analysis on data collected from mothers (n=297) and fathers (n=207) participating in the extended Infant Feeding, Activity and Nutrition Trial (InFANT Extend) when their children were 36 months of age. The main outcome variables were the use of the internet for information gathering for parents' own health and child health, feeding, and playing. Binary logistic regression was used to examine the sociodemographic predictors of outcomes., Results: Compared with fathers (n=296), a higher proportion of mothers (n=198) used the internet for information on their own health (230, 78.5% vs 93, 46.5%), child health (226, 77.1% vs 84, 42.4%), child feeding (136, 46.3% vs 35, 17.5%), and child play (123, 42.1% vs 28, 14.0%) and intended to use Facebook to connect with other parents (200, 74.9% vs 43, 30.5%). Despite the high use of the internet to support family health behaviors, only 15.9% (47/296) of mothers reported consulting health practitioners for advice and help for their own or their child's weight, diet, or physical activity. Sociodemographic predictors of internet use differed between mothers and fathers and explained only a small proportion of the variance in internet use to support healthy family lifestyle behaviors., Conclusions: Our findings support the use of the internet and Facebook as an important potential avenue for reaching mothers with information relevant to their own health, child health, child diet, and active play. However, further research is required to understand the best avenues for engaging fathers with information on healthy family lifestyle behaviors to support this important role in their child's life., Trial Registration: ISRCTN Registry ISRCTN81847050; http://www.isrctn.com/ISRCTN81847050., (©Rachel Laws, Adam D Walsh, Kylie D Hesketh, Katherine L Downing, Konsita Kuswara, Karen J Campbell.

Background: Approximately 80% of internet users access health information online and patients with chronic illnesses especially rely on internet-based resources. YouTube ranks second among the most accessed websites worldwide and hosts an increasing number of videos with medical information. However, their quality is sometimes unscientific, misleading, or even harmful., Objective: As little is known about YouTube as a source of information on psoriasis, we aimed to investigate the quality of psoriasis-related videos and, if necessary, point out strategies for their improvement., Methods: The quality of the 100 most viewed psoriasis-related videos was assessed using the DISCERN instrument and the Global Quality Scale (GQS) by categorizing the videos into useful, misleading, and dangerous and by evaluating the reception of the videos by users., Results: Evaluation of the videos exhibited a total of 117,221,391 views and a total duration of 10:28 hour. The majority of clips contained anecdotal personal experiences with complementary and alternative psoriasis treatments, topical treatments, and nutrition and diets being the most frequently addressed topics. While advertisements accounted for 26.0% (26/100) of the videos, evidence-based health information amounted to only 20.0% (20/100); 32.0% (32/100) of the videos were classified as useful, 52.0% (52/100) as misleading, and 11.0% (11/100) as even dangerous. The quality of the videos evaluated by DISCERN and GQS was generally low (1.87 and 1.95, respectively, on a 1 to 5 scale with 5 being the maximum). Moreover, we found that viewers rated poor-quality videos better than higher quality videos., Conclusions: Our in-depth study demonstrates that nearly two-thirds of the psoriasis-related videos we analyzed disseminate misleading or even dangerous content. Subjective anecdotal and unscientific content is disproportionately overrepresented and poor-quality videos are predominantly rated positively by users, while higher quality video clips receive less positive ratings. Strategies by professional dermatological organizations are urgently needed to improve the quality of information on psoriasis on YouTube and other social media., (©Simon M Mueller, Pierre Jungo, Lucian Cajacob, Simon Schwegler, Peter Itin, Oliver Brandt.

Background: Physical activity (PA) has health benefits for people with type 2 diabetes (T2D). Indeed, regular PA is considered an important part of any T2D management plan, yet most patients adopt a sedentary lifestyle. Exercise referral schemes (ERS) have the potential to effectively promote physical activity among T2D patients, and their effectiveness may be enhanced when they are supported by computer-based technologies. The 'TRIPL-A' study (i.e., a TRIal to promote PhysicaL Activity among patients in the young-old age affected by T2D) aims to assess if realizing an innovative ERS, based on a strong partnership among general practitioners, specialist physicians, exercise specialists, and patients, and supported by a web-based application (WBA), can effectively lead sedentary older T2D patients to adopt an active lifestyle., Methods: A randomized controlled design will be used, and an ERS, supported by a WBA, will be implemented. 300 physically inactive T2D patients (aged 65-74 years) will be assigned to either an intervention or control arm. Control arm patients will only receive behavioral counseling on physical activity and diet, while intervention arm patients will also undergo an 18-month (3 day/week), discontinuously supervised aerobic exercise training program. The trial will be divided into six three-month periods: during first, third and fifth period, an exercise specialist will supervise the training sessions and, using the WBA, prescribe exercise progression and monitor exercise adherence. Patients will exercise on their own in the other periods. Patients' sedentary behaviors (primary outcome), PA level, fitness status, metabolic profile, psychological well-being, quality of life, and use of health care services (secondary outcomes) will be assessed at baseline and at 6, 12, and 18 months from baseline. Repeated measure ANCOVAs will be used to compare the intervention and control arm with respect to each study outcome measure., Discussion: Primary and secondary outcome results will allow us to evaluate the effectiveness of an ERS, specifically designed for the management of T2D clinical conditions and supported by a WBA, in promoting PA within Italian primary care settings., Trial Registration: This trial is retrospectively registered under the Australian New Zealand Clinical Trials Registry (reference number: ACTRN12618001164280 ; registered 13 July 2018).

Background: As the elderly population and prevalence of dementia is increasing, it is necessary to have a better comprehension of the influence of specific factors on cognitive function. Dementia is not an inevitable consequence of ageing. Lifestyle factors might either increase or decrease the risk. Even though different studies have focused on individual factors, only a few studies are available which assess all these factors as a whole. Available evidence on these factors is mainly from high income countries and much less evidence is available from low and middle income countries. As cognition is critical for elderly people to engage in a physically independent life, we aimed to identify the associated factors of cognition., Methods: This was a descriptive cross sectional study performed with 421 elderly people dwelling in residential care facilities for the aged in two selected districts in the Southern Province of Sri Lanka. Cognition was assessed using the Mini Mental State Examination (MMSE). Independent sample t test, ANOVA and regression analyses were used to explore associated factors for cognition. The statistical significance was kept at bonferroni adjusted p < 0.004., Results: The study included elderly people with a mean age of 71.9 ± 6.7 years and of them 65.8% were females. Factors affecting higher level of cognition were, having upper secondary, advanced and higher education; being married; arriving at the facility on one's own accord; being visited by family members; higher physical activity levels and engaging in social and leisure activities (p < 0.004). The factors, namely physical activity level, educational status, visits by family members and engaging in leisure activities were the predictors of cognition in the regression model., Conclusion: Though there were several factors that associated with the level of cognition such as educational status, marital status, reason for attending the facility, visits by family members, physical activity levels and participation in social and leisure activities, only the factors, such as physical activity levels, visits by family members, educational status and engaging in leisure activities were the predictors of cognition.

Physical inactivity, sedentary behavior, and poor diet are contributing to the rise in chronic disease rates throughout the world. HealtheSteps™ is a lifestyle prescription program focused on reducing risk factors for chronic disease through in-person coaching sessions, goal setting and tracking, and technology supports. A process evaluation was conducted alongside a pragmatic randomized controlled trial to: (a) explore the acceptability of HealtheSteps™ program from coach and participant perspectives; and (b) identify where the program can be improved. Participants at risk or diagnosed with a chronic disease were recruited from five primary care/health services organizations into HealtheSteps™. Participants met with a trained coach bi-monthly for 6 months and set goals for physical activity (step counts), exercise (moderate to vigorous activity), and healthy eating. Coaches were interviewed at month 6 and participants at month 12 (6 months postprogram). All coach interviews (n = 12) were analyzed along with a purposeful sample of participant interviews (n = 13). Coaches found that HealtheSteps™ was easy to deliver and recommendations for exercise and healthy eating were helpful. Including discussions on participant readiness to change, along with group sessions, and more in-depth healthy eating resources were suggested by coaches to improve the program. Participants described the multiple avenues of accountability provided in the program as helpful. However, more feedback and interaction during and postprogram from coaches were suggested by participants. HealtheSteps™ is an acceptable program from the perspectives of both coaches and participants with suggested improvements not requiring significant changes to the core program design.

The objective of this article was to conduct a treatment development study to examine the feasibility, acceptability, and preliminary efficacy of treating depressed, overweight/obese adolescents using both an exercise regimen and a Cognitive Behavioral Therapy (CBT) protocol modified to address aspects of healthy living and nutrition (CBT plus healthy lifestyle; CBT-HL). A randomized controlled repeated measures design was used to test the hypothesis that CBT-HL would lead to greater reductions in depressed mood and weight compared to CBT for Depression Only (CBT). Participants (n=33; 24 in CBT-HL condition) included 33 adolescents (median age 15, 73% female, 61% white, 36% Hispanic) who met DSM-IV criteria for Current Major Depressive Episode (MDE) and had BMI ≥ 85th percentile. CBT-HL was found to be feasible to implement with most adolescents. Both conditions resulted in improvement in depressed mood. The CBT-HL protocol was more effective in stabilizing weight status as assessed by BMI. Percent time spent in MVPA was increased at 12 weeks for adolescents in CBT-HL compared to those in CBT. The CBT-HL protocol was acceptable to most, but not all, adolescents, and resulted in an improvement in depressed mood as well as stabilization of weight status. A larger study to test efficacy and moderators of treatment outcome is necessary to better understand which adolescents would benefit most from the increased demands of exercise and adhering to nutrition recommendations in addition to standard CBT for depression. Revisions to the treatment protocol to support weight loss, not just stabilization, are also suggested.

Background: The prevalence of smoking varies across ethnic groups in developed countries, but little is known about ethnic variations in specific aspects of nicotine dependence (ND). We conducted item-response analyses in current smokers to compare ND factors across five ethnic groups., Methods: Data were obtained from a population-based, multi-ethnic cohort study conducted in the Netherlands. The Fagerström Test for Nicotine Dependence (FTND) was assessed in 1147 Dutch, 991 South-Asian Surinamese, 1408 African Surinamese, 1396 Turkish, and 584 Moroccan smokers (N = 5526). We tested whether the factorial structure of the FTND was invariant across ethnic groups using a multi-group confirmatory factor analysis. FTND item and total scores and factor means were compared across groups., Results: The two-factor model representing "morning smoking" and "smoking patterns" provided an adequate fit. The items "Cigarettes smoked daily" and "Time until first cigarette" showed differential item functioning (DIF) as a function of ethnicity. Three out of four ethnic minority groups scored significantly higher on both factors compared to the Dutch origin group (all p < 0.001) before and after taking DIF into account, while the African Surinamese scored higher only on "morning smoking" when DIF was accounted for., Discussion: The factor structure of the FTND is not measurement invariant across ethnic groups in this population-based sample. Accounting for DIF affecting the nicotine dependence factor scores, although South-Asian Surinamese, Turkish, and Moroccan groups showed higher levels of dependence than the Dutch origin group, genetic as well as environmental factors may account for the observed differences., (Copyright © 2018 Elsevier B.V.

A hospital-based, case-control study was conducted to investigate the association between lifestyle patterns and risk of colorectal cancer (CRC) in the north of Vietnam. Demographic factors employed for the models were age, sex, marital status, occupation, education, income, smoking status, alcohol consumption, vegetable consumption, tea, coffee consumption, and physical activity (PA). Individuals of both groups (n = 154 for the control group and n = 136 for the CRC group) were interviewed using a questionnaire by trained interviewers. The findings showed that moderate PA was inversely associated with CRC risk: odds ratio (OR) = 0.19, 95% confidence interval (CI) = 0.10 to 0.36 with P < .01. The total PA showed that the highest tertile (>2.7 MET-h/d) was associated with the reduced risk of CRC compared with the lowest tertile one after controlling for confounding factors: adjusted OR = 0.25, 95% CI = 0.09 to 0.74, P < .01. Sedentary time was associated with an increased level of CRC risk by 57% as compared between the highest tertile and the lowest one after controlling for confounding factors. Daily consumption of vegetables and 1 to 3 cups of tea per day or more were also associated with decreased risk of CRC. Despite promising findings, a limitation of this research is that it did not establish a temporal relationship between risk factors and CRC due to its retrospective design. However, this is the first analytic study highlighting the role of the active lifestyle pattern associated with reduced CRC risk in Vietnamese adults.

Good health is the result of a healthy lifestyle, where caring about physical activity and nutrition are key concerns. However, in today's society, nutritional disorders are becoming increasingly frequent, affecting children, adults, and elderly people, mainly due to limited nutrition knowledge and the lack of a healthy lifestyle. A commonly adopted therapy to these imbalances is to monitor physical activity and daily habits, such as recording exercise or creating custom meal plans to count the amount of macronutrients and micronutrients acquired in each meal. Nowadays, many health tracking applications (HTA) have been developed that, for instance, record energy intake as well as users' physiological parameters, or measure the physical activity during the day. However, most existing HTA do not have a uniform architectural design on top of which to build other applications and services. In this manuscript, we present system architecture intended to serve as a reference architecture for building HTA solutions. In order to validate the proposed architecture, we performed a preliminary evaluation with 15 well recognized experts in systems and software architecture from different entities around world and who have estimated that our proposal can generate architecture for HTA that is adequate, reliable, secure, modifiable, portable, functional, and with high conceptual integrity. In order to show the applicability of the architecture in different HTA, we developed two telemonitoring systems based on it, targeted to different tasks: nutritional coaching (Food4Living) and physical exercise coaching (TrainME). The purpose was to illustrate the kind of end-user monitoring applications that could be developed.

Physical inactivity is one of the leading modifiable risk factors for global mortality, with an estimated 20% to 30% increased risk of death compared with those who are physically active. The "behavior" of physical activity (PA) is multifactorial, including social, environmental, psychological, and genetic factors. Abundant scientific evidence has demonstrated that physically active people of all age groups and ethnicities have higher levels of cardiorespiratory fitness, health, and wellness, and a lower risk for developing several chronic medical illnesses, including cardiovascular disease, compared with those who are physically inactive. Although more intense and longer durations of PA correlate directly with improved outcomes, even small amounts of PA provide protective health benefits. In this state-of-the-art review, the authors focus on "healthy PA" with the emphasis on the pathophysiological effects of physical inactivity and PA on the cardiovascular system, mechanistic/triggering factors, the role of preventive actions through personal, education/environment, and societal/authoritative factors, as well as factors to provide guidance for caregivers of health promotion regarding PA. Sustainable and comprehensive programs to increase PA among all individuals need to be developed and implemented at local, regional, national, and international levels to effect positive changes and improve global health, especially the reduction of cardiovascular disease., (Copyright © 2018.

Peripheral artery disease is a common yet underdiagnosed cause of morbidity worldwide. Significant recent advances in management have resulted in new guideline creation for the diagnosis and management of peripheral artery disease in the United States and Europe. Here, we analyze each set of guidelines with special attention to those areas where the 2 groups disagree. Both groups emphasize the importance of risk factor reduction, including smoking cessation, lipid lowering, blood pressure management, and glucose control. The U.S. guidelines place additional attention on lifestyle factors, including regular physical activity and supervised exercise. The European guidelines offer a number of recommendations for revascularization in patients with limb-threatening ischemia. Both agree that more evidence is needed to understand which patients are at highest risk for tissue loss. A consistent charge to each committee fostering a similar approach to available data and more randomized studies would align recommendations across both organizations., (Copyright © 2018 American College of Cardiology Foundation.

Background Measures of subclinical atherosclerosis are predictors of future cardiovascular outcomes as well as of physical and cognitive functioning. The menopausal transition is associated with accelerated progression of atherosclerosis in women. The prospective association between a healthy lifestyle during the midlife and subclinical atherosclerosis is unclear. Methods and Results Self-reported data on smoking, diet, and physical activity from 1143 women in the Study of Women's Health Across the Nation were used to construct a 10-year average Healthy Lifestyle Score ( HLS ) during the midlife. Markers of subclinical atherosclerosis were measured 14 years after baseline and included common carotid artery intima-media thickness ( CCA - IMT ), adventitial diameter ( CCA - AD ), and carotid plaque. The associations of average HLS with CCA - IMT and CCA - AD were estimated using linear models; the association of average HLS with carotid plaque was estimated using cumulative logit models. Average HLS was associated with smaller CCA - IMT and CCA - AD in the fully adjusted models ( P=0.0031 and <0.001, respectively). Compared with participants in the lowest HLS level, those in the highest level had 0.024 mm smaller CCA - IMT (95% confidence interval: -0.048, 0.000), which equals 17% of the SD of CCA - IMT , and 0.16 mm smaller CCA - AD (95% confidence interval: -0.27, -0.04), which equals 24% of the SD of CCA - AD . Among the 3 components of the HLS , abstinence from smoking had the strongest association with subclinical atherosclerosis. Conclusions Healthy lifestyle during the menopausal transition is associated with less subclinical atherosclerosis, highlighting the growing recognition that the midlife is a critical window for cardiovascular prevention in women.

Background: Physical activity guidelines state that children should achieve at least 60 minutes of moderate to vigorous physical activity (MVPA) on each day of the week. Accurate assessment of adherence to these guidelines should, ideally, include measurement over 7 days. When less than 7 days of data are available, researchers often report the average minutes of MVPA per day as a proxy for 7-day measurement. The aim of this study was to compare prevalence estimates generated by average MVPA per day versus MVPA assessed over 7 days., Methods: Data were collected as part of the Healthy Lifestyles Programme. One class from each school was randomized to wear a GENEActiv accelerometer for 8 days. The percentages of children achieving an average of ≥60 minutes of MVPA per day and those achieving ≥60 minutes of MVPA on each of 7 days were calculated., Results: A total of 807 children provided 7 days of data. When the average MVPA per day was calculated, 30.6% (n = 247) of children accumulated ≥60 minutes of MVPA per day. Only 3.2% (n = 26) accumulated ≥60 minutes of MVPA on every day of the week., Conclusion: Previous studies utilizing average MVPA per day are likely to have overestimated the percentage of children meeting recommendations.

Non-communicable diseases (NCDs) are a major problem as they are the leading cause of death and represent a substantial economic cost. The 'Developmental Origins of Health and Disease Hypothesis' proposes that adverse stimuli at different life stages can increase the predisposition to these diseases. In fact, adverse in utero programming is a major origin of these diseases due to the high malleability of embryonic development. This review provides a comprehensive analysis of the scientific literature on in utero programming and NCDs highlighting potential medical strategies to prevent these diseases based upon this programming. We fully address the concept and mechanisms involved in this programming (anatomical disruptions, epigenetic modifications and microbiota alterations). We also examine the negative role of in utero programming on the increased predisposition of NCDs in the offspring, which introduces the passive medical approach that consists of avoiding adverse stimuli including an unhealthy diet and environmental chemicals. Finally, we extensively discuss active medical approaches that target the causes of NCDs and have the potential to significantly and rapidly reduce the incidence of NCDs. These approaches can be classified as direct in utero programming modifications and personalized lifestyle pregnancy programs; they could potentially provide transgenerational NCDs protection. Active strategies against NCDs constitute a promising tool for the reduction in NCDs.

Background: How long one lives, how many years of life are spent in good and poor health, and how the population's state of health and leading causes of disability change over time all have implications for policy, planning, and provision of services. We comparatively assessed the patterns and trends of healthy life expectancy (HALE), which quantifies the number of years of life expected to be lived in good health, and the complementary measure of disability-adjusted life-years (DALYs), a composite measure of disease burden capturing both premature mortality and prevalence and severity of ill health, for 359 diseases and injuries for 195 countries and territories over the past 28 years., Methods: We used data for age-specific mortality rates, years of life lost (YLLs) due to premature mortality, and years lived with disability (YLDs) from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 to calculate HALE and DALYs from 1990 to 2017. We calculated HALE using age-specific mortality rates and YLDs per capita for each location, age, sex, and year. We calculated DALYs for 359 causes as the sum of YLLs and YLDs. We assessed how observed HALE and DALYs differed by country and sex from expected trends based on Socio-demographic Index (SDI). We also analysed HALE by decomposing years of life gained into years spent in good health and in poor health, between 1990 and 2017, and extra years lived by females compared with males., Findings: Globally, from 1990 to 2017, life expectancy at birth increased by 7·4 years (95% uncertainty interval 7·1-7·8), from 65·6 years (65·3-65·8) in 1990 to 73·0 years (72·7-73·3) in 2017. The increase in years of life varied from 5·1 years (5·0-5·3) in high SDI countries to 12·0 years (11·3-12·8) in low SDI countries. Of the additional years of life expected at birth, 26·3% (20·1-33·1) were expected to be spent in poor health in high SDI countries compared with 11·7% (8·8-15·1) in low-middle SDI countries. HALE at birth increased by 6·3 years (5·9-6·7), from 57·0 years (54·6-59·1) in 1990 to 63·3 years (60·5-65·7) in 2017. The increase varied from 3·8 years (3·4-4·1) in high SDI countries to 10·5 years (9·8-11·2) in low SDI countries. Even larger variations in HALE than these were observed between countries, ranging from 1·0 year (0·4-1·7) in Saint Vincent and the Grenadines (62·4 years [59·9-64·7] in 1990 to 63·5 years [60·9-65·8] in 2017) to 23·7 years (21·9-25·6) in Eritrea (30·7 years [28·9-32·2] in 1990 to 54·4 years [51·5-57·1] in 2017). In most countries, the increase in HALE was smaller than the increase in overall life expectancy, indicating more years lived in poor health. In 180 of 195 countries and territories, females were expected to live longer than males in 2017, with extra years lived varying from 1·4 years (0·6-2·3) in Algeria to 11·9 years (10·9-12·9) in Ukraine. Of the extra years gained, the proportion spent in poor health varied largely across countries, with less than 20% of additional years spent in poor health in Bosnia and Herzegovina, Burundi, and Slovakia, whereas in Bahrain all the extra years were spent in poor health. In 2017, the highest estimate of HALE at birth was in Singapore for both females (75·8 years [72·4-78·7]) and males (72·6 years [69·8-75·0]) and the lowest estimates were in Central African Republic (47·0 years [43·7-50·2] for females and 42·8 years [40·1-45·6] for males). Globally, in 2017, the five leading causes of DALYs were neonatal disorders, ischaemic heart disease, stroke, lower respiratory infections, and chronic obstructive pulmonary disease. Between 1990 and 2017, age-standardised DALY rates decreased by 41·3% (38·8-43·5) for communicable diseases and by 49·8% (47·9-51·6) for neonatal disorders. For non-communicable diseases, global DALYs increased by 40·1% (36·8-43·0), although age-standardised DALY rates decreased by 18·1% (16·0-20·2)., Interpretation: With increasing life expectancy in most countries, the question of whether the additional years of life gained are spent in good health or poor health has been increasingly relevant because of the potential policy implications, such as health-care provisions and extending retirement ages. In some locations, a large proportion of those additional years are spent in poor health. Large inequalities in HALE and disease burden exist across countries in different SDI quintiles and between sexes. The burden of disabling conditions has serious implications for health system planning and health-related expenditures. Despite the progress made in reducing the burden of communicable diseases and neonatal disorders in low SDI countries, the speed of this progress could be increased by scaling up proven interventions. The global trends among non-communicable diseases indicate that more effort is needed to maximise HALE, such as risk prevention and attention to upstream determinants of health., Funding: Bill & Melinda Gates Foundation., (Copyright © 2018 The Author(s).

Background: Poor understanding of diabetes management targets is associated with worse disease outcomes. Patients may use different information than providers to assess their diabetes control. In this study, we identify the information patients use to gauge their current level of diabetes control and explore patient-perceived barriers to understanding the hemoglobin A1c value (HbA1c)., Methods: Adults who self-reported a diagnosis of diabetes were recruited from outpatient, academically-affiliated, Internal Medicine clinics. Semi-structured interviews were conducted with participants and collected data were analyzed using thematic analysis., Results: The mean age of the 25 participants was 56.8 years. HbA1c was one of several types of information participants used to assess diabetes control. Other information included perceived self-efficacy and adherence to self-care, the type and amount of medications taken, the presence or absence of symptoms attributed to diabetes, and feedback from self-monitoring of blood glucose. Most participants reported familiarity with the HbA1c (22 of 25), though understanding of the value's meaning varied significantly. Inadequate diabetes education and challenges with patient-provider communication were cited as common barriers to understanding the HbA1c., Conclusions: In addition to the HbA1c, several categories of information influenced participants' assessments of their diabetes control. Increased provider awareness of the factors that influence patients' perceptions of diabetes control can inform effective, patient-centered approaches for communicating vital diabetes-related information, facilitating behavior change towards improved patient outcomes.

Interest in slowing or reversing the process of aging continues to grow and has encouraged the growth of an entire anti-aging industry. However, there is a dearth of data based on randomized trials in humans to support proposed therapies to address the various complex processes involved in aging. Hormonal therapies, in particular, have little data to support safe use and are associated with some degree of risk. Experimental data in animal models suggest possible molecular targets but their use in clinical medicine is far in the future. Observational data guide the current recommendations to maintain a healthy lifestyle, including consumption of a healthful diet and achieving adequate sleep, toward the goal of slowing the aging process. Patients may ask their physicians to offer opinions about treatments they hope will increase their health span. To counsel patients effectively, it is important for physicians to understand the basic principles of anti-aging science. Maintenance of supportive, nonjudgmental therapeutic relationships with patients is critical to avoid harmful and costly treatments while trying to present reliable evidence for available anti-aging therapies., (Written permission from the American Academy of Family Physicians is required for reproduction of this material in whole or in part in any form or medium.)

Background: Little is known about factors contributing to physical activity (PA) in American Indian (AI) populations. Addressing this gap is paramount as sedentary activity and obesity continue to increase in this population. The purpose of this study was to determine factors associated with PA among AI families with young children., Methods: Height and weight of both adult (n = 423) and child (n = 390) were measured, and surveys assessed demographics, PA, stress (adult only), sleep, and screen time. Separate multivariate logistic regression models were constructed for adults and children (reported as adjusted odds ratios, aORs)., Results: For adults, age (aOR = 0.952; P ≤ .001), television viewing (aOR = 0.997; P = .01), and computer use (aOR = 0.996; P = .003) decreased the odds of being active. For children, high adult activity (aOR = 1.795; P ≤ .01), longer weekday sleep (aOR = 1.004; P = .01), and family income >$35,000 (aOR = 2.772; P = .01) increased the odds of being active. We found no association between adult PA with stress or adult sleep or between child PA with body mass index and screen time., Conclusions: Given the complexity of the factors contributing to obesity among AI families, multigenerational interventions focused on healthy lifestyle change such as decreasing adult screen time and increasing child sleep time may be needed to increase PA within AI families.

Evolution by natural selection eliminates maladaptive traits from a species, and yet Alzheimer's Disease (AD) persists with rapidly increasing prevalence globally. This apparent paradox begs an explanation within the framework of evolutionary sciences. Here, I summarize and critique previously proposed theories to explain human susceptibility to AD, grouped into 8 distinct hypotheses based on the concepts of novel extension of the lifespan; lack of selective pressure during the post-reproductive phase; antagonistic pleiotropy; rapid brain evolution; delayed neuropathy by selection for grandmothering; novel alleles selected to delay neuropathy; by-product of selection against cardiovascular disease; and thrifty genotype. Subsequently, I describe a new hypothesis inspired by the concept of mismatched environments. Many of the factors that enhance AD risk today may have been absent or functioned differently before the modern era, potentially making AD a less common affliction for age-matched individuals before industrialization and for the majority of human history. Future research is needed to further explore whether changes in environments and lifestyles across human history moderate risk factors and susceptibility to AD., (Copyright © 2018 Elsevier B.V.

Context: Obesity-related hyperinsulinism may impede lifestyle-initiated weight loss., Objective: Proof-of-concept study to investigate the amplifying effects of diazoxide (DZX)-mediated insulin suppression on lifestyle-induced weight loss in nondiabetic, hyperinsulinemic, obese men., Design: Twelve-month study comprising an initial 6-month, double-blind trial, followed by a partially de-blinded 6-month extension in men with obesity with a body mass index of 30 to 37.5 kg/m2 and a fasting serum C-peptide level >1.00 nM. Patients were randomized into three treatment groups: DZX + placebo (DZX + PL), DZX + metformin (DZX + MTF), and double PL (PL + PL)., Results: At 6 months, DZX treatment was associated with a 6.1-kg PL-subtracted decline in fat mass (FM), and at 12 months, FM had decreased by a total of 15.7 ± 2.5 kg. Twelve months of DZX treatment was also associated with a significant decline in systolic (-6.6%) and diastolic (-8.6%) blood pressure and low-density lipoprotein-cholesterol (-18%) and triglycerides (-43%) and a 39% rise in high-density lipoprotein-cholesterol. These effects were achieved at the cost of a small rise in fasting glucose (95% CI: 0.2 to 1.0 mM) and hemoglobin A1c (95% CI: -0.08% to 0.44%). There were no differences between DZX monotherapy and the combination of DZX + MTF., Conclusion: High-dose DZX treatment of 1 year resulted in a substantial decrease in FM, blood pressure, and lipid levels at the cost of a small rise in blood glucose levels.

Background: The PEACH™ randomized controlled trial measured changes to children's food and activity behaviours following participation in a weight management programme. We have previously reported a 10% reduction in body mass index z-score at intervention end (6-month post-baseline) that was maintained to 24 months with no further intervention for the full study sample., Objectives: The objective of the study is to report changes in food and activity outcomes in the full sample at (i) the end of the 6-month intervention and (ii) 24-month post-baseline (18-month post-intervention)., Methods: Changes in dietary and activity outcomes were assessed over time (baseline: n = 169, 8.1 ± 1.2 years, body mass index z-score 2.72 ± 0.62). Dietary intake was assessed using the Child Dietary Questionnaire, and times spent active and sedentary were assessed using a study-specific questionnaire. Linear mixed models were used., Results: There were significant time effects for all Child Dietary Questionnaire scores and activity and sedentary behaviours in the expected direction. Significant sex effects were observed for fruit and vegetable and sweetened beverages scores and for time spent in small screen-based activity., Conclusions: This is one of few child weight management studies to report short-term and long-term behaviour outcomes. It demonstrates that an intervention promoting food and activity behaviours consistent with guidelines can achieve modest changes, mediating improvements in relative weight., (© 2018 World Obesity Federation.)

Introduction: Breast cancer is the most common malignancy among adolescents and young adults (AYAs) women aged 15 to 39 years at diagnosis. An improved understanding of modifiable factors that mitigate the risks of the development of breast cancer may allow for future strategies to reduce the incidence of AYA breast cancer., Method: A literature review was conducted to report upon associations between modifiable lifestyle factors and breast cancer risk., Results: Higher levels of physical activity, lower red meat intake, and higher intake of plants appear to decrease the risk of developing AYA breast cancer, whereas associations between obesity and AYA breast cancer risk were less straightforward., Conclusions: Further research, ideally in large prospective trials, is needed to truly understand modifiable risk factors for the development of AYA breast cancer.

Health care workers (HCWs) are prone to a heavy psycho-physical workload. Health promotion programs can help prevent the onset of chronic and work-related diseases. The aim of the STI-VI 'before-and-after' study, with assessments scheduled at 6 and 12 months, was to improve the lifestyle of HCWs with at least one cardiovascular risk factor. A tailored motivational counseling intervention, focusing on dietary habits and physical activity (PA) was administered to 167 HCWs (53 males; 114 females). BMI, waist circumference, blood pressure, and cholesterol, triglyceride, and blood glucose levels were measured before and after the intervention. The 6-month results (total sample and by gender) showed a marked effect on lifestyle: PA improved (+121.2 MET, p = 0.01), and diets became more similar to the Mediterranean model (+0.8, p < 0.001). BMI dropped (-0.2, p < 0.03), and waist circumference improved even more (-2.5 cm; p < 0.001). Other variables improved significantly: total and LDL cholesterol (-12.8 and -9.4 mg/dL, p < 0.001); systolic and diastolic blood pressure (-4.4 and -2.5 mmHg, p < 0.001); blood glucose (-1.5 mg/dL, p = 0.05); and triglycerides (significant only in women), (-8.7 mg/dL, p = 0.008); but HDL cholesterol levels dropped too. If consolidated at 12 months, these results indicate that our intervention can help HCWs maintain a healthy lifestyle and work ability.

We carried out a case-control study to investigate the effects of some lifestyle patterns on the occurrence of colorectal cancer (CRC) in the city of Mecca, Saudi Arabia. Parameters included BMI, employment, family income, educational level, family size, exercise, cancer awareness, diabetes, and hypertension. Individuals of both groups (n=164 for control group, n=137 for CRC group) completed a questionnaire with the help of trained dietitians. Results showed that limited cancer awareness was found to increase the risk of CRC [odds ratio (OR)=49.96, 95% confidence interval (CI): 11.45-217.9, P<0.001]. There was a linear trend (P-trend<0.001) of low educational level in increasing the risk of CRC. Mainly, illiterate individuals showed the highest risk of developing CRC (OR=116.8, 95% CI: 14.7-927.75, P<0.001). In addition, the results indicated a linear trend (P-trend<0.001) of low family income in increasing the risk of CRC. The highest risk of CRC was shown with family income less than 5000 Saudi riyals (OR=64.38, 95% CI: 12.82-323.28, P<0.001). Other risk factors included a sedentary lifestyle, unemployment, and diabetes. Surprisingly, low BMI was associated with increasing incidence of CRC (OR=0.92, 95% CI: 0.88-0.96, P<0.001). However, family size and hypertension had no effect (P>0.05) on the incidence of CRC. Our study emphasizes the effect of active lifestyle patterns and cancer awareness in decreasing the incidence of CRC in the Mecca region.

The prevalence of obesity-related nonalcoholic fatty liver disease (NAFLD) is rising. NAFLD may result in nonalcoholic steatohepatitis (NASH), progressing to liver cirrhosis. Weight loss is recommended to treat obesity-related NASH. Lifestyle intervention may improve NASH; however, pertinent trials have so far focused on overweight patients, whereas patients with obesity are at highest risk of developing NAFLD. Furthermore, reports of effects on liver fibrosis are scarce. We evaluated the effect of lifestyle intervention on NAFLD in a real-life cohort of morbidly obese patients. In our observational study, 152 patients underwent lifestyle intervention, with a follow-up of 52 weeks. Noninvasive measures of obesity, metabolic syndrome, liver steatosis, liver damage, and liver fibrosis were analyzed. Treatment response in terms of weight loss was achieved in 85.1% of patients. Dysglycemia and dyslipidemia improved. The proportion of patients with fatty liver dropped from 98.1 to 54.3% ( P < 0.001). Weight loss >10% was associated with better treatment response ( P = 0.0009). Prevalence of abnormal serum transaminases fell from 81.0 to 50.5% ( P < 0.001). The proportion fibrotic patients, as determined by the NAFLD fibrosis score, dropped from 11.8 to 0% ( P < 0.05). Low serum levels of adiponectin correlated with degree of liver damage, i.e., serum liver transaminases ( r = -0,32, P < 0.05). Serum levels of adiponectin improved with intervention. In conclusion, lifestyle intervention effectively targeted obesity and the metabolic syndrome. Liver steatosis, damage and fibrosis were ameliorated in this real-life cohort of morbidly obese patients, mediated in part by changes in the adipokine profile. Patients with weight loss of >10% seemed to benefit most. NEW & NOTEWORTHY We demonstrate new evidence that lifestyle intervention is effective in treating NAFLD in the important group of patients with (morbid) obesity. Although current guidelines on the therapy of NASH recommend weight loss of 5-7%, weight reduction >10% may be favorable in morbid obesity. Serum levels of adipokines correlate with liver damage, which is indicative of their pathogenetic importance in human NASH. Our study adds to the limited body of evidence that NAFLD-associated liver fibrosis may resolve with lifestyle intervention.

In people with schizophrenia several factors are associated with poor quality of life (QoL), namely, lifestyle-related factors and psychological factors. However, there has been little research on the impact of these factors on QoL. Therefore, the relation between lifestyle-related factors, psychological factors, and QoL in people with schizophrenia was assessed. A cross-sectional study was conducted among 115 patients (25% women, 50% inpatients). QoL was measured by World Health Organisation Quality of Life- Brief Version. Lifestyle-related factors were assessed, namely physical activity (International Physical Activity Questionnaire- Short Form), sleep quality (Pittsburgh Sleep Quality Index) and dietary intake (Mediterranean Diet score). Psychological factors such as self-esteem (Rosenberg Self-Esteem Scale) and autonomous motivation (Behavioural Regulation Questionnaire- version 3) were also measured. Regression analyses were performed to identify significant predictors of QoL. Results showed that self-esteem predicted better global, physical, psychological and environmental QoL. Physical activity predicted better global and physical QoL, while sedentary time predicted poor social and environmental QoL. Identifying predictors of QoL has implication for the effective design and delivery of lifestyles interventions, including physical activity, dietary education and smoking cessation in people with schizophrenia. Adopting healthy lifestyles may lead to improved physical health, psychological well-being and QoL in this population., (Copyright © 2018 Elsevier B.V. All rights reserved.)

This Views and Reviews explores existing data regarding the impact of nutrition, supplements, and lifestyle changes as they relate to weight on the fertility of both men and women. Challenges and shortcomings in developing and performing well-designed studies of nutrition and fertility are reviewed in these five papers, and the best evidence is presented. Recommendations are made based on the data, such as they are. It appears that folic acid supplementation above the level used by women to reduce the risk of neural tube defects may be of value in producing favorable pregnancy outcomes. Certain polyunsaturated fatty acids may have a beneficial effect on fertility, and a Mediterranean diet may prove advantageous in both men and women. Data do not consistently support a beneficial effect of vitamin D on reproduction, and caffeine use has not been shown to have a deleterious effect. Alcohol use may negatively impact reproductive success, and smoking appears to have a clearly negative impact in both men and women. Present data consistently show that obesity is associated with reduced reproductive efficiency in both women and men, but the data do not confirm that weight loss proximate to attempts at conception will reverse this effect. We would do well to appreciate that the ongoing state of being obese appears to be more relevant to reproduction than changing the obese state., (Copyright © 2018 American Society for Reproductive Medicine.

This work examines whether the increased all-cause and cardiovascular disease (CVD) mortality associated with polypharmacy could be offset by a healthy lifestyle. We included a prospective cohort of 3,925 individuals representative of the Spanish population aged ≥60 years, who were recruited in 2000-2001 and followed up through 2014. Polypharmacy was defined as treatment with ≥5 medications. The following lifestyle behaviors were considered healthy: not smoking, eating a healthy diet, being physically active, moderate alcohol consumption, low sitting time, and adequate sleep duration. Individuals were classified into three lifestyle categories s: unfavorable (0-2), intermediate (3-4) favorable (5-6). Over a median 13.8-y follow-up, 1,822 all-cause and 675 CVD deaths occurred. Among individuals with polypharmacy, intermediate and favorable lifestyles were associated with an all-cause mortality reduction (95% confidence interval [CI]) of 47% (34-58%) and 54% (37-66%), respectively; 37% (9-56%) and 60% (33-76%) for CVD death, respectively. The theoretical adjusted hazard ratio (95%CI) associated with replacing 1 medication with 1 healthy lifestyle behavior was 0.73 (0.66-0.81) for all-cause death and 0.69 (0.59-0.82) for CVD death. The theoretical adjusted hazard ratio (95%CI) for all-cause and CVD mortality associated with simply reducing 1 medication was 0.88 (0.83-0.94) and 0.83 (0.76-0.91), respectively. Hence, adherence to a healthy lifestyle behavior can reduce mortality risk associated with polypharmacy in older adults.

Background: Physical inactivity and being overweight are modifiable lifestyle risk factors that consistently have been associated with a higher risk of postmenopausal breast cancer in observational studies. One biologic hypothesis underlying this relationship may be via endogenous sex hormone levels. It is unclear if changes in dietary intake, physical activity, or both, are most effective in changing these hormone levels., Objective: This systematic review and meta-analysis examines the effect of reduced caloric dietary intake and/or increased exercise levels on breast cancer-related endogenous sex hormones., Methods: We conducted a systematic literature search in MEDLINE, Embase, and Cochrane's Central Register of Controlled Trials (CENTRAL) up to March 2017. Main outcome measures were breast cancer-related endogenous sex hormones. Randomized controlled trials (RCTs) reporting effects of reduced caloric intake and/or exercise interventions on endogenous sex hormones in healthy, physically inactive postmenopausal women were included. Studies including women using hormone therapy were excluded. The methodological quality of each study was assessed by the Cochrane's risk of bias tool., Results: From the 2599 articles retrieved, seven articles from six RCTs were included in this meta-analysis. These trials investigated 1588 healthy postmenopausal women with a mean age ranging from 58 to 61 years. A combined intervention of reduced caloric intake and exercise, with durations ranging from 16 to 52 weeks, compared with a control group (without an intervention to achieve weight loss) resulted in the largest beneficial effects on estrone treatment effect ratio (TER) = 0.90 (95% confidence interval (CI) = 0.83-0.97), total estradiol TER = 0.82 (0.75-0.90), free estradiol TER = 0.73 (0.66-0.81), free testosterone TER = 0.86 (0.79-0.93), and sex hormone biding globulin (SHBG) TER = 1.23 (1.15-1.31). A reduced caloric intake without an exercise intervention resulted in significant effects compared with control on total estradiol TER = 0.86 (0.77-0.95), free estradiol TER = 0.77 (0.69-0.84), free testosterone TER = 0.91 (0.84-0.98), and SHBG TER = 1.20 (1.06-1.36). Exercise without dietary change, versus control, resulted in borderline significant effects on androstenedione TER = 0.97 (0.94-1.00), total estradiol TER = 0. 97 (0.94-1.00), and free testosterone TER = 0. 0.97 (0.95-1.00)., Conclusions and Relevance: This meta-analysis of six RCTs demonstrated that there are beneficial effects of exercise, reduced caloric dietary intake or, preferably, a combination of exercise and diet on breast cancer-related endogenous sex hormones in physically inactive postmenopausal women.

Obesity increases risk of endometrial cancer through dysregulation of estrogen and insulin signaling. The primary aim of this study was to evaluate the impact of metformin or lifestyle intervention on endometrial proliferation in postmenopausal obese women. Secondary aims included evaluating obesity-related biomarkers and adverse events experienced. Obese, postmenopausal women with prediabetes were randomized into four groups for a 16-week intervention using a 2 (metformin 1700 mg/day vs. placebo) × 2 (lifestyle intervention vs. no lifestyle intervention) factorial design. Pre- and postintervention endometrial proliferation, anthropometrics, body composition, and serum biomarkers (sex hormones, sex hormone binding globulin, IGF-I, adiponectin, omentin, insulin, glucose, and others) were assessed. Data were analyzed with linear regression models and false-discovery rate correction. Of 576 women approached for the study, 52 attended initial screening, 29 were eligible and randomized, and 26 completed the study. Lifestyle intervention resulted in significant loss of weight (-4.23 kg, P = 0.006) and total fat mass (-3.23 kg, P < 0.001). Participants receiving metformin lost 3.43 kg of weight ( P = 0.023), but this was not statistically significant after multiple comparisons adjustment controlling false-discovery rate to 10%. Endometrial proliferation was low at baseline (mean 7.1%) and remained unchanged by 16 weeks, but included substantial variability. Metformin and lifestyle intervention produced minor changes to serum biomarkers. Lifestyle intervention produced the most significant changes in weight and body composition. While it is known that obese postmenopausal women are at increased risk for endometrial cancer, improved biomarkers are needed to stratify risk and test prevention strategies, particularly at the endometrial tissue level.

Background: The effectiveness of lifestyle intervention for weight loss on cardiometabolic risk factors among overweight and obese individuals in the community setting remains inconclusive. This study aimed to evaluate the effect of a 6-month weight loss lifestyle intervention on cardiometabolic risk factors among overweight and obese women and the sustainability of the changes in those markers at 12-month follow-up, comparing an intervention group with a control group., Methods: A total of 243 participants from MyBFF@home were included in this study. Fasting blood samples at baseline, 6- and 12-month were assessed for fasting plasma glucose (FPG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides. The effect of the intervention on cardiometabolic risk markers were investigated within and between study groups using t-test and general linear model (GLM) repeated measure ANOVA., Results: Results from repeated measures ANOVA showed intervention effect only in TC where significant reduction was found in the intervention group (- 0.26 mmol/L [95% CI: - 0.47 to - 0.06], p < 0.01) compared to the control group (- 0.06 mmol/L [95% CI: - 0.28 to 0.17]) at 12 months. At 6 months, TC was reduced significantly in both groups but only intervention group retained the reduction in maintenance phase while, the level increased significantly in the control group (0.22 mmol/L [95% CI: 0.06 to 0.38]). This attributed to significant increase in TC/HDL-C ratio in the control group during maintenance phase (0.32 [95% CI: 0.15 to 0.50], p < 0.001). The intervention group also showed trend of reduction in FPG at 6 months and further decreased during maintenance phase (- 0.19 mmol/L [95% CI: - 0.32 to - 0.06], p < 0.01). At 6 months HDL-C was maintained in the intervention group but reduced significantly in the control group (- 0.05 mmol/L [95% CI: - 0.10 to - 0.01], p < 0.05). No significant difference was detected in both markers when compared between groups., Conclusions: In the context of low socio-economic communities, this study supports that weight loss related lifestyle modifications over a 6-month period could improve selected cardiometabolic risk factors, particularly fasting glucose, TC and HDL-C in overweight and obese women with favourable sustainability over a 12-month period.

Background: The prevalence of overweight and obesity among Malaysian women remained high over the past three decades. Collaboration with existing community at-risk may be feasible for wide-scale prevention of overweight and obesity in the country. The aims of this study were to examine the impact of community-based lifestyle intervention among overweight and obese women on their anthropometric and body composition changes as compared to the usual care group., Methods: This was a quasi-experimental study conducted in low-cost flats in Kuala Lumpur, Malaysia. A total of 255 overweight and obesity individuals aged between 18 to 59 years old were assigned to either the lifestyle intervention group (n = 169) or the usual care group (n = 146) over a period of 6 months. Individuals in the intervention group received 6 individual lifestyle counselling comprised of physical activity, diet counselling and self-monitoring components aimed to achieve at least 5% weight loss while individuals in the usual care group obtained six sessions of health care seminars from health care providers. These individuals were then followed-up for another 6 months without any intervention as part of maintenance period., Results: An intention-to-treat analysis of between-groups at 6-month of intervention (β, 95% CI) revealed greater changes in weight among intervention individuals' (- 1.09 kg vs. -0.99; p < 0.018) as compared to the control group. These changes were not sustained during the maintenance phase (between 6 and 12 months). Overall significant improvement at 12th month was found for visceral fat (- 0.78 vs. -0.64; p-value = 0.017), although no significant changes between groups were detected either during intervention or maintenance phase (p > 0.05). Individuals in the intervention group showed a significant increase for skeletal muscle mass (0.13 kg) than those individuals in the control group (- 0.37 kg), p = 0.033, throughout the study period., Conclusion: This study provides evidence that an overweight and obesity prevention program can be implemented in a community setting, with some reduction of several anthropometric and body composition parameters.

Background: Obesity is an emerging global public health concern as it is related to chronic diseases and its impact to health related quality of life. The aim of this study was to assess the effect of weight reduction on health related quality of life (HRQOL) among obese and overweight housewives., Methods: Data on 123 obese and overweight housewives in the intervention group from the MyBFF@home study were utilised. A validated Malaysian Malay version of Obesity Weight Loss Quality of Life (OWLQOL) questionnaire was administered at baseline and 6 months after intervention. Descriptive analysis, univariate analysis, paired t-test and multiple logistic regression were performed using SPSS Version 22., Results: Mean body mass index (BMI) was 31.5 kg/m 2 (SD:4.13), with 51 participants classified as overweight (41.5%) while 72 were obese (58.5%). About 72% of the housewives experienced weight reduction (62% reduced weight less than 5% and 11% reduced weight more than 5% of their baseline weight). There was a significant improvement in HRQOL with a pre-intervention total mean score of 59.82 (SD: 26.60) and post-intervention of 66.13 (SD: 22.82), p-value < 0.001. By domain, the highest post intervention mean score was self-image 71.46 (SD: 22.85), followed by social stigma 68.77 (SD: 28.70), physical 61.83 (SD: 24.25) and trying to lose weight 61.24 (SD: 27.32). There was no significant association between weight reduction and HRQOL improvement., Conclusion: Weight loss intervention programme utilizing behavioural modification has led to a significant improvement in HRQOL among overweight and obese housewives.

We aimed to examine the temporal association between physical activity and successful aging. The analyses involved 1,584 adults aged 49 + years living west of Sydney (Australia), who did not have cancer, coronary artery disease and stroke at baseline and who were followed over 10 years. Participants provided information on the performance of moderate or vigorous activities and walking exercise and this was used to determine total metabolic equivalents (METs) minutes of activity per week. Successful aging status was determined through interviewer-administered questionnaire and was classified as the absence of: depressive symptoms, disability, cognitive impairment, respiratory symptoms and systemic conditions (e.g. cancer, coronary artery disease). 249 (15.7%) participants (mean age 59.9 ± 6.1) had aged successfully 10 years later. After multivariable adjustment; older adults in the highest level of total physical activity (≥5000 MET minutes/week; n = 71) compared to those in the lowest level of total physical activity (<1000 MET minutes/week; n = 934) had 2-fold greater odds of aging successfully than normal aging, odds ratio, OR, 2.08 (95% confidence intervals, CI, 1.12-3.88). Older adults who engaged in high levels of total physical activity, well above the current recommended minimum level had a greater likelihood of aging successfully 10 years later.

Background: Success with lifestyle change, such as weight loss, tobacco cessation, and increased activity level, using electronic health (eHealth) has been demonstrated in numerous studies short term. However, evidence on how to maintain the effect long-term has not been fully explored, even though there is a pressing need for long-term solutions. Recent studies indicate that weight loss can be achieved and maintained over 12 and 20 months in a primary care setting using a collaborative eHealth tool. The effect of collaborative eHealth in promoting lifestyle changes depends on competent and skilled dieticians, nurses, physiotherapists, and occupational therapists acting as eHealth coaches. How such health care professionals perceive delivering asynchronous eHealth coaching and which determinants they find to be essential to achieving successful long-term lifestyle coaching have only been briefly explored and deserve further exploration., Objective: The aim of this study is to analyze how health care professionals perceive eHealth coaching and to explore what influences successful long-term lifestyle change for patients undergoing hybrid eHealth coaching using a collaborative eHealth tool., Methods: A total of 10 health care professionals were recruited by purposive sampling. They were all women aged 36 to 65 years of age with a mean age of 48 years of age. A total of 8/10 (80%) had more than 15 years of experience in their field, and all had more than six months of experience providing eHealth lifestyle coaching using a combination of face-to-face meetings and asynchronous eHealth coaching. They worked in 5 municipalities in the Region of Southern Denmark. We performed individual, qualitative, semistructured, in-depth interviews in their workplace about their experiences with health coaching about lifestyle change, both for their patients and for themselves, and mainly how they perceived using a collaborative eHealth solution as a part of their work., Results: The health care professionals all found establishing and maintaining an empathic relationship essential and that asynchronous eHealth lifestyle coaching challenged this compared to face-to-face coaching. The primary reason was that unlike typical in-person encounters in health care, they did not receive immediate feedback from the patients. We identified four central themes relevant to the health care professionals in their asynchronous eHealth coaching: (1) establishing an empathic relationship, (2) reflection in asynchronous eHealth coaching, (3) identifying realistic goals based on personal barriers, and (4) staying connected in asynchronous coaching., Conclusions: Establishing and maintaining an empathic relationship is probably the most crucial factor for successful subsequent eHealth coaching. It was of paramount importance to get to know the patient first, and the asynchronous interaction aspect presented challenges because of the delay in response times (both ways). It also presented opportunities for reflection before answering. The health care professionals found they had to provide both relational communication and goal-oriented coaching when using eHealth solutions. Going forward, the quality of the health care professional-patient interaction will need attention if patients are to benefit from collaborative eHealth coaching fully., (©Carl Joakim Brandt, Gabrielle Isidora Søgaard, Jane Clemensen, Jens Søndergaard, Jesper Bo Nielsen.

Overwhelming evidence exists that lifelong exercise is associated with a longer health span, delaying the onset of 40 chronic conditions/diseases. What is beginning to be learned is the molecular mechanisms by which exercise sustains and improves quality of life. The current review begins with two short considerations. The first short presentation concerns the effects of endurance exercise training on cardiovascular fitness, and how it relates to improved health outcomes. The second short section contemplates emerging molecular connections from endurance training to mental health. Finally, approximately half of the remaining review concentrates on the relationships between type 2 diabetes, mitochondria, and endurance training. It is now clear that physical training is complex biology, invoking polygenic interactions within cells, tissues/organs, systems, with remarkable cross talk occurring among the former list., (Copyright © 2018 Cold Spring Harbor Laboratory Press; all rights reserved.)

Objective: We report a mixed method evaluation of the feasibility and implementation of the AgeWell goal-setting intervention to promote healthy ageing later life., Method: Researcher field notes, goal-setting interview content, and semi-structured interviews with participants were content analysed to review trial implementation and participants' perspective on the goal-setting and mentoring intervention., Results: 75 people were recruited: 21 in the goal-setting and 22 in the goal-setting with mentoring arms of the intervention. Goal-setting was feasible in the main domains of interest. Adherence to the protocol was good and the mentoring schedule was adhered to. Participants reported satisfaction with their goal attainment, but barriers for non-achievement were also identified. Recommendations for small changes to the intervention included reducing the number of goals., Conclusions: Participants understood the goal-setting process, and were able to set realistic and achievable lifestyle goals. The intervention and the procedures were acceptable but changes in how goal-setting is both introduced and monitored are needed for wider implementation., Clinical Implications: Goal-setting can be a useful process to help people alter their lifestyle to allow them to age more successfully and reduce risk factors associated with dementia.

Purpose: The purpose of this study is to test the feasibility of delivering an intervention that combines healthy lifestyle behaviors related to weight management with asthma self-management, the Living Healthy with Asthma intervention, to children who have asthma., Methods and Design: Using a mixed design, the feasibility study of the 12-week Living Healthy with Asthma intervention was conducted with a single group of children diagnosed with asthma. Pretest and posttest data were collected on asthma-related (self-management, metered dose inhaler [MDI] skill, asthma severity, quality of life [QOL]), and healthy lifestyle variables (body mass index [BMI], dietary quality). A matched comparison sample was drawn from a separate study that tested the same asthma self-management component (single intervention) used in the feasibility study to determine if the Living Healthy with Asthma intervention worked as well as the single intervention for improving children's asthma self-management., Results: Thirteen school-aged children were enrolled in the feasibility study. There were significant reductions in BMI z-scores (P = 0.007), and improvements in vegetable servings (P = 0.03), MDI skill (P = 0.005), children's QOL (P < 0.001), and parents' QOL (P = 0.03). When comparing the feasibility group with the matched comparison group (n = 13), there were no significant differences in asthma self-management, MDI skill, or asthma severity after the interventions., Practice Implications: Findings supported the feasibility of implementing the combined intervention, and it was not inferior to the single intervention-which supports nurses' efforts to help families manage multiple health problems., (© 2018 Wiley Periodicals, Inc.)

The growing recognition that "health" takes place outside of the hospital and clinic, plus recent advances in mobile and wearable devices, have propelled the field of mobile health (mHealth). Cardiovascular disease and prevention are major opportunities for mHealth, as mobile devices can monitor key physiological signals (e.g., physical activity, heart rate and rhythm) for promoting healthy behaviors, detecting disease, and aid in ongoing care. In this review, the authors provide an update on cardiovascular mHealth by highlighting recent progress and challenges with mobile and wearable devices for assessing and promoting physical activity and fitness, and for monitoring heart rate and rhythm for the detection and management of atrial fibrillation., (Copyright © 2018 American College of Cardiology Foundation.
