Background Diaries are used in sexual behaviour research to reduce recall bias. Diary collection via mobile phone text messaging (SMS) has not been trialled previously in sexual behaviour research. This randomized controlled trial compared SMS, paper and online diaries on response rate, timeliness, completeness of data and acceptability. The correlation between behaviour reported in all three types of diaries and data collected in a retrospective questionnaire was also determined. Methods Participants were recruited by telephone and randomised into one of three groups. They completed weekly sexual behaviour diaries for 3 months by SMS, online or paper (by post). An online survey was conducted at the end of 3 months to compare retrospective reports to the diaries and assess opinions on the diary collection method. Results 72 participants were enrolled in the study, 24 in each group. Online diaries were more likely to be submitted late than SMS diaries (p<0.001). 3.9% of SMS diaries, 3.1% of paper diaries and 0.5% of online diaries were incomplete (p=0.001). Online data collection was the preferred mode for 51%. 65 participants completed the end point retrospective questionnaire. The correlation between the diary and questionnaire on sexual risk classification was substantial (κ=0.74) regardless of diary mode. Conclusions SMS is a convenient and timely method of collecting brief behavioural data, but online data collection was preferable to most participants and more likely to be complete. Data collected in retrospective sexual behaviour questionnaires were found to agree substantially with data collected through weekly self-reported diaries. [ABSTRACT FROM AUTHOR]

Background Replication is a vital part of the research process and has recently received considerable attention. Analyses using publicly available data should, if adequately described, be reproducible without assistance from the original investigators. Using data from the US National Health and Nutrition Examination Survey (NHANES), a recent study reported a statistically significant difference in cardiovascular disease risk comparing subgroups of sexual minority men. We attempted to reproduce these findings and assessed whether the results were robust to alternative analytic strategies and assumptions. Methods We used the exclusion criteria and coding strategy described in the original paper to construct our analytical data set. Sampling weights were constructed in accordance with NHANES analytical guidelines. We estimated crude and covariate-adjusted associations between sexual orientation and vascular age using the regression models specified in the original report. We also conducted a series of sensitivity analyses to improve on the original findings. Results Our replication attempt was partially successful: we replicated the general trends reported in the original analysis, but not identical effect estimates. Importantly, we identified a potential misapplication of the Framingham Risk Score; correcting for this increased the probability that the reported null hypothesis test was a type I error. Conclusions This paper supports the recent calls for greater transparency and improved reporting in research. Even with a publicly available and well-documented data source, we were unable to exactly replicate another study's original findings. Our sensitivity analyses revealed key issues in the original analysis and demonstrate the scientific importance of research replication. [ABSTRACT FROM AUTHOR]

Background Population ageing is a global challenge and understanding the dynamics of living arrangements in later life and their implications for the design of appropriate housing and long-term care is a critical policy issue. Existing research has focused on the study of transitions into residential care in the UK. This paper investigates transitions into sheltered accommodation among older people in England and Wales between 1993 and 2008. Methods The study uses longitudinal data constructed from pooled observations across waves 2-18 of the British Household Panel Survey (BHPS) data, focusing on individuals aged 65 and over who lived in private housing at baseline and who were observed for two consecutive time points. A discrete-time logistic regression model was used to examine the association of transitioning into sheltered accommodation with a range of demographic, health and socioeconomic predictors. Results Demographic (age, region), socioeconomic factors (housing tenure, having a washing machine) and contact with health professionals (number of visits to the general practitioner, start in use of health visitor) were significant determinants of an older person's move into sheltered accommodation. Conclusions Transitions into sheltered accommodation are associated with a range of demographic and socioeconomic characteristics as well as service use but not with health. Such results indicate that this type of housing option may be accessible by individuals with relatively good health, but may be limited to those who are referred by gatekeepers. Policymakers could consider making such housing option available to everyone, as well as providing incentives for building lifecourse-sensitive housing in the future. [ABSTRACT FROM AUTHOR]

Background: Media guidelines for suicide reporting are available in many countries. However, to what extent the mass media comply with the guidelines is unknown. Few studies are available that investigate systematically whether the mass media reflect the epidemiological reality of suicide deaths in their articles. Methods: Based on the WHO media guidelines, this study investigated the characteristics of newspaper articles of suicides in three Chinese communities, namely Hong Kong, Taiwan and Guangzhou. Epidemiological comparisons were conducted to identify the age and gender differences between the suicide victims as reported in the newspapers and the official records of suicide deaths in all three places. Results: The results found that one media characteristic complied with the WHO media guidelines (ie, only about 2% of the articles were printed on the front page), but there were a number of instances of non-compliance (ie, only 4--14% provided sources for help-seeking and 27--90% printed with photos). The epidemiological comparisons revealed an over-representation of younger suicides and an under-representation of late-life suicides in the newspapers of all three places. Furthermore, female suicides were found to be under-reported in Taiwan and Guangzhou newspapers, but not in Hong Kong papers. Conclusion: Non-compliant suicide articles are prevalent in the newspapers of these three Chinese settings. The observed media misrepresentations may potentially mislead the public and the policy makers about the actual risk for suicide in some demographic groups. [ABSTRACT FROM AUTHOR]

Background and aims: The social gradient in smoking is well known, with higher rates among those in less advantaged socioeconomic position. Some recent research has reported that personality characteristics partly explain this gradient. However, the majority of existing work is limited by cross-sectional designs unsuitable to determine whether differences in conscientiousness are a predictor or a product of social inequalities. Adopting a life course perspective, we investigated in the current paper the influence of conscientiousness in early and mid-life on the social gradient in smoking and the role of potential confounding factors in a large longitudinal cohort study. Methods: Using data from the 1958 National Child Development Study, we examined the extent to which two measures of conscientiousness, one assessed with a personality questionnaire at age 50 and one derived from three related items at 16 years in childhood, explained the social gradient of smoking at age 50 by comparing nested logistic regression models that included social class at birth, cognitive ability, attention and conduct problems at age 7, and educational qualification. Results: Childhood conscientiousness was a significant predictor of smoking at 50 years (OR=0.86, CI (95%) 0.84 to 0.88), explaining 5.0% of the social gradient independent of all other variables. Childhood conscientiousness was a stronger predictor than adult conscientiousness, statistically accounting for the observed direct association of adult conscientiousness with smoking. Conclusions: Conscientiousness may be a predictor rather than a product of social differences in smoking. Inclusion of personality measures and adoption of a life course perspective add significantly to our understanding of health inequalities. [ABSTRACT FROM AUTHOR]

Background Depression and obesity are significant health concerns currently facing adolescents worldwide. This paper investigates the associations between obesity and related risk behaviours and depressive symptomatology in an Australian adolescent population. Methods Data from the Australian Capital Territory It’s Your Move project, an Australian community-based intervention project were used. In 2012, 800 students (440 females, 360 males) aged 11–14 years (M=13.11 years, SD=0.62 years), from 6 secondary schools were weighed and measured and completed a questionnaire which included physical activity, sedentary behaviour and dietary intake. Weight status was defined by WHO criteria. A cut-off score ≥10 on the Short Mood and Feelings Questionnaire indicated symptomatic depression. Logistic regression was used to test associations. Results After controlling for potential confounders, results showed significantly higher odds of depressive symptomatology in males (OR=1.22, p<0.05) and females (OR=1.12, p<0.05) who exceeded guidelines for daily screen-time leisure sedentary activities. Higher odds of depressive symptoms were seen in females who consumed greater amounts of sweet drink (OR=1.18, p<0.05), compared to lower female consumers of sweet drinks, and males who were overweight/obese also had greater odds of depressive symptoms (OR=1.83, p<0.05) compared to male normal weight adolescents. Conclusions This study demonstrates the associations between obesogenic risks and depression in adolescents. Further research should explore the direction of these associations and identify common determinants of obesity and depression. Mental health outcomes need to be included in the rationale and evaluation for diet and activity interventions. [ABSTRACT FROM AUTHOR]

Background Evidence is conflicting regarding the relationship between low maternal alcohol consumption and birth outcomes. This paper aimed to investigate the association between alcohol intake before and during pregnancy with birth weight and gestational age and to examine the effect of timing of exposure. Methods A prospective cohort in Leeds, UK, of 1303 pregnant women aged 18-45 years. Questionnaires assessed alcohol consumption before pregnancy and for the three trimesters separately. Categories of alcohol consumption were divided into ≤2 units/week and ≥2 units/week with a nondrinking category as referent. This was related to size at birth and preterm delivery, adjusting for confounders including salivary cotinine as a biomarker of smoking status. Results Nearly two-thirds of women before pregnancy and over half in the first trimester reported alcohol intakes above the Department of Health (UK) guidelines of ≤2 units/week. Associations with birth outcomes were strongest for intakes ≥2 units/week before pregnancy and in trimesters 1 and 2 compared to non-drinkers. Even women adhering to the guidelines in the first trimester were at significantly higher risk of having babies with lower birth weight, lower birth centile and preterm birth compared to non-drinkers, after adjusting for confounders (p<0.05). Conclusions We found the first trimester to be the period most sensitive to the effect of alcohol on the developing fetus. Women adhering to guidelines in this period were still at increased risk of adverse birth outcomes. Our findings suggest that women should be advised to abstain from alcohol when planning to conceive and throughout pregnancy. [ABSTRACT FROM AUTHOR]

Background The relationship between childhood residential mobility and health in the UK is not well established; however, research elsewhere suggests that frequent childhood moves may be associated with poorer health outcomes and behaviours. The aim of this paper was to compare people in the West of Scotland who were residentially stable in childhood with those who had moved in terms of a range of health measures. Methods A total of 850 respondents, followed-up for a period of 20 years, were included in this analysis. Childhood residential mobility was derived from the number of addresses lived at between birth and age 18. Multilevel regression was used to investigate the relationship between childhood residential mobility and health in late adolescence (age 18) and adulthood (age 36), accounting for socio-demographic characteristics and frequency of school moves. The authors examined physical health measures, overall health, psychological distress and health behaviours. Results Twenty per cent of respondents remained stable during childhood, 59% moved one to two times and 21% moved at least three times. For most health measures (except physical health), there was an increased risk of poor health that remained elevated for frequent movers after adjustment for socio-demographic characteristics and school moves (but was only significant for illegal drug use). Conclusions Risk of poor health was elevated in adolescence and adulthood with increased residential mobility in childhood, after adjusting for sociodemographic characteristics and school moves. This was true for overall health, psychological distress and health behaviours, but physical health measures were not associated with childhood mobility. [ABSTRACT FROM AUTHOR]

Background The Baby-Friendly Hospital Initiative (BFHI) has been implemented by WHO and Unicef with a view to protect, promote and support breast feeding. This paper aims to assess the influence of the BFHI on breastfeeding indicators in Brazil, using data from the 2nd Survey of Breastfeeding Prevalence, conducted in 2008. Methods Data on 64 municipalities were analysed: a total of 65 936 infants under the age of 1 year who were covered by the 2008 immunisation campaign. The outcomes of interest were breast feeding in the first hour of life in infants under 1 year of age; exclusive breast feeding on the first day after hospital discharge in infants under 4 months of age; exclusive breast feeding in infants under 2, 3 and 6 months of age; and pacifier use in infants under 6 months of age. The influence of birth in baby-friendly hospitals (BFHs) on these end points was analysed by means of Poisson regression with robust variance for complex samples. Findings Infants born in BFHs were 9% more likely to be breast fed in the first hour of life and 6% more likely to be breast fed on the first day at home. Exclusive breast feeding was 13%, 8% and 6% more likely in infants under the ages of 2, 3 and 6 months, respectively, born in BFHs. Birth in a BFH also correlated with significant less pacifier use. Conclusions The BFHI has had an impact on several indicators of breast feeding. The authors hope the results of this study will make policy makers and health professionals aware of the importance and potential of this strategy. [ABSTRACT FROM AUTHOR]

Background In industrialised countries, approximately 5-20% of women smoke during pregnancy. We aim to study the association between smoking during pregnancy and adverse perinatal outcomes. Methods A retrospective population-based cohort study using data on all singleton births between 1991 and 2010 (n=1 164 953) derived from the Finnish Medical Birth Register. Results Of all the mothers included, 82.3% were nonsmokers, 2.6% quit smoking during the first trimester of pregnancy, 12.5% smoked throughout pregnancy and 2.7% had no information on smoking. Continuing smoking after the first trimester of the pregnancy was associated with an increased prevalence of admission to a neonatal intensive care unit, stillbirth, preterm birth (<37 gestational weeks), low birth weight (LBW, <2500 g), small for gestational age (SGA, <-2 SDs) and major congenital anomaly compared with nonsmokers. Smoking cessation reduced the risk of prematurity, stillbirth, LBW and SGA close to or at similar levels as those of non-smokers. Tobacco exposure in early pregnancy resulted in a 19% increased prevalence of admission to neonatal intensive care unit and a 22% increased prevalence of major congenital anomaly compared with non-smokers. Conclusions Smoking cessation appeared to reduce pregnancy risks close to those of non-smoking peers. Exposure to early pregnancy smoking was, however, associated with an increased admission to neonatal intensive care and an increased prevalence of major congenital anomalies. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effectiveness of a worksite vitality intervention on vigorous physical activity (VPA), fruit intake, aerobic capacity, mental health and need for recovery after work among older hospital workers (ie, 45 years and older). Methods: The 6-month intervention was evaluated using a randomised controlled trial design. Workers who were randomised to the intervention group (n=367; control: n=363) received the Vital@Work intervention containing (1) a Vitality Exercise Program (VEP) combined with (2) three visits to Personal Vitality Coach. The VEP consisted of a weekly yoga session, a weekly workout session and weekly unsupervised aerobic exercising. Free fruit was provided at the VEP. Data on the outcome measures were collected (ie, year 2009--2010) at baseline (n=730) and 6 months of follow-up after baseline (n=575) using questionnaires, accelerometers and 2 km walk tests. Effects were analysed according to the intention-to-treat principle with complete cases (n=575) and imputed data (n=730) using linear regression analyses. Additional analyses were performed for high yoga and workout compliance (ie, >mean number of sessions). Results: Effects were found for sports activities (β=40.4 min/week, 95% CI 13.0 to 67.7) and fruit intake (β=2.7 pieces/week, 95% CI 0.07 to 4.7) and were stronger for workers with high compliance to yoga (sport: β=49.6 min/week, 95% CI 13.9 to 85.2; fruit: β=3.8 pieces/week, 95% CI 1.1 to 6.4) and workout sessions (sport: b=72.9 min/week, 95% CI 36.1 to 109.8; fruit: β=4.0 pieces/week, 95% CI 1.1 to 6.4). The intervention group lowered their need for recovery, when compared to controls (β=-3.5, 95% CI -6.4 to -0.54), with stronger effects for high workout compliance (β=-5.3, 95% CI -9.3 to -1.3). No effects were found on VPA, aerobic capacity or mental health. Conclusions: Implementation of worksite yoga and workout facilities and minimal fruit interventions should be considered by employers to promote transitions into healthier lifestyles and thereby health.

Objectives: To investigate the mechanisms through which marital status exerts long-term effects on depressive symptoms among women and to evaluate the relative importance of psychological, social and financial resources in mediating this relationship. Methods: Data came from 6107 female respondents to a nationally representative longitudinal data set from the USA (National Survey of Families and Households 1987e1988/1992e1994). Mediation was investigated using semi-longitudinal structural equation modelling and bias-corrected bootstrapped CIs. Latent constructs with multiple indicators were used to measure depressive symptoms, primary and secondary social integration and self-esteem. Results: The total effect of marital status on subsequent depressive symptoms was statistically significant for all marital statuses relative to those in first marriages controlling for age, education, race, number of children younger than 5 in the household, T1 depressive symptoms and marital status transitions between waves; all groups experienced higher levels of depressive symptoms than those in first marriages. These effects were completely mediated for never-married women and partially mediated for separated/divorced, widowed and cohabiting women. Adjusted household income was the largest mediator for the separated/divorced, widowed and never-married, but primary social integration also played a role. Self-esteem was the only significant mediator for the remarried and cohabiting and was also important in explaining differences between the first-married and separated/divorced. Conclusion: This study demonstrates that the reasons why marital status has an influence on subsequent depressive symptoms varies depending on the specific marital status being compared with the married.

Background: Previous studies, all of <20 years of followup, have suggested an association between lung function and the risk of fatal stroke. This study investigates the stability of this association in a cohort followed for 4 decades. Methods: The Bergen Clinical Blood Pressure Survey was conducted in Norway in 1964--1971. The risk of fatal stroke associated with forced expiratory volume after one second (FEV1) was estimated with Cox proportional hazards regression, making progressive adjustment for potential confounders. Results: Of 5617 (84%) participants with recorded baseline FEV1, 462 died from stroke over 152 786 subsequent person-years of follow-up according to mortality statistics of 2005; mean (SD) follow-up was 27 (12) years. An association between baseline FEV1 (L) and fatal stroke was observed; HR=1.38 (95% CI 1.11 to 1.71) and HR=1.62 (95% CI 1.22 to 2.15) for men and women, respectively (adjusted for age and height). The findings were not explained by smoking, hypertension, diabetes, atherosclerosis, socioeconomic status, obstructive lung disease, physical inactivity, cholesterol or body mass index and persisted in subgroups of never-smokers, subgroups without respiratory symptoms and survivors of the first 20 years of follow-up. For male survivors with a valid FEV1 at follow-up (1988--1990) (n=953), baseline FEV1 (L) indicated a possible strong and independent association to the risk of fatal stroke after adjustments for individual changes in FEV1 (ml/year) (HR 1.95 (95% CI 0.98 to 3.86)). Conclusion: There is a consistent, independent and long-lasting association between lung function and fatal stroke, probably irrespective of changes during adult life. [ABSTRACT FROM AUTHOR]

Background Improving Access to Psychological Therapies (IAPT) is a new programme designed to reduce disease burden to the individual and economic burden to the society of common mental health problems (CMHP). This is the first study to look at the impact of IAPT on health service utilisation and sickness absence using routine data. Method The authors used pseudonymised secure and privately linked (SAPREL) routinely collected primary, secondary care and clinic computer data from two pilot localities. The authors explored antidepressant prescribing, accident and emergency and outpatients attendances, inpatient stays, bed days, and sick certification. The authors compared the registered population with those with CMHP. The authors then made a 6 months before and after comparison of people referred to IAPT with age-sex and practice-matched controls. Results People with CMHP used more health resources than those without CMHP: more prescriptions of antidepressants 5.25 (95% CI 5.38 to 5.13), inpatient episodes 4.89 (95% CI 5.0 to 4.79), occupied bed days 1.25 (95% CI 0.95 to 1.55), outpatient 1.5 (95% CI 1.40 to 1.63) and emergency department attendances 0.34 (95% CI 0.31 to 0.37), and medical certificates 0.29 (95% CI 0.26 to 0.32). Comparison of service utilisation 6 months before and after referral to IAPT was associated with reduced use of emergency department attendances (mean difference: 0.12 (95% CI 0.06 to 0.19, p<0.001)). However, the number of prescriptions of antidepressants increased mean difference 0.15 (95% CI 0.020.29, p=0.028). Conclusions People with CMHP use more healthcare resources. Referral to the IAPT programme is associated with a subsequent reduction in emergency department attendances, sickness certification and improved adherence to drug treatment. [ABSTRACT FROM AUTHOR]

Background: There have been few evaluations of national area-based interventions. This study evaluated the early effects of Communities for Children (CfC) on children and their families and whether the effectiveness differed for more disadvantaged families. Methods: A quasi-experimental cohort study in socioeconomically disadvantaged communities in Australia. Mothers of children aged 2--3 years participated at wave 1; 1488 children in CfC communities and 714 children in comparison communities. Outcome measures included child health and development, family functioning and parenting, and services and community. Results: After controlling for background factors, there were beneficial effects associated with CfC. At wave 3, in CfC areas children had higher receptive vocabulary (mean difference (MD) 0.25, 95% CI --0.02 to 0.51; p=0.07), parents showed less harsh parenting (MD --0.14, 95% CI --0.30 to 0.02; p=0.08) and higher parenting self-efficacy (MD 0.11, 95% CI 0.00 to 0.21; p=0.04). Fewer children living in CfC sites were living in a jobless household (OR 0.56, 95% CI 0.32 to 0.95; p=0.03) but children's physical functioning (MD --0.26, 95% CI --0.53 to 0.00; p=0.05) was worse in CfC sites. For children living in households with mothers with low education there were reduced child injuries requiring medical treatment (MD --0.61, 95% CI --0.07 to --1.13; p=0.03) and increased receptive vocabulary (MD 0.57, 95% CI 0.06 to 1.08; p=0.03). Conclusions: CfC showed some benefits for child receptive vocabulary, parenting and reducing jobless households and two adverse effects. Children living in the most disadvantaged households also benefited. [ABSTRACT FROM AUTHOR]

Background With growing numbers of older people worldwide, improving and maintaining quality of life during the extended years of life are a major focus for healthcare providers and policymakers. Some studies have suggested frailty may be associated with worse quality of life. Objectives To review the associations between frailty and quality of life among community-dwelling older people. Methods A systematic literature search was performed using five databases for cross-sectional and longitudinal studies examining associations between frailty and quality of life among community-dwelling older people published in 2000 or later. Reference lists of relevant studies were also manually searched. Authors were requested for data for a meta-analysis if necessary. Meta-analysis was attempted for studies using the same frailty criteria and quality-of-life instrument. Methodological quality, heterogeneity and publication bias were assessed. Results The systematic review identified 5145 studies, among which 11 cross-sectional studies and two longitudinal studies were included in this review. Meta-analysis including four cross-sectional studies using the Fried Phenotype and 36-Item Short Form Health Survey showed that those classified as frail and prefrail had significantly lower mental and physical quality-of-life scores than those classified as non-frail. High heterogeneity and possible publication bias were noted. Conclusions This systematic review and meta-analysis has demonstrated the evidence of a consistent inverse association between frailty/prefrailty and quality of life among community-dwelling older people. Interventions targeted at reducing frailty may have the additional benefit of improving corresponding quality of life. More longitudinal analysis is required to determine this effect.

Background Childhood maltreatment has been linked to preterm birth (<37 weeks gestation) in some studies, but these findings have been inconsistent, and it remains unclear whether type, timing or severity of maltreatment are associated with risk of preterm birth. The aim of this observational study was to explore type of maltreatment (child and adolescent physical and sexual abuse and harsh parenting) as risk factors for preterm birth. Methods We examined these associations in a cross-sectional analysis of the Nurses' Health Study II cohort of female nurses. Women completed a questionnaire about experiences of sexual abuse, physical abuse or harsh parenting, along with pregnancy outcomes. Logistic regression models adjusted for relevant covariates including age, race, alcohol and cigarette use during pregnancy, age at menarche, marital status, adult income, body mass index (kg/m²²) at age 18, physical abuse in pregnancy, and childhood socioeconomic position. Results Among 51 434 first births, 4110 were preterm (8% of births). Forced sexual activity in childhood or adolescence was associated with a 22% increased odds of preterm birth (OR=1.22, 95% CI 1.10 to 1.35). Maltreatment involving sexual touch, physical abuse or harsh parenting was not associated with preterm birth in this sample. Conclusions Women who experience forced sexual activity in childhood or adolescence may have an increased likelihood of delivering preterm in adulthood. [ABSTRACT FROM AUTHOR]

Background Falls are a significant cause of morbidity after stroke. The aim of this review was to identify, critically appraise and summarise risk prediction models for the occurrence of falling after stroke. Methods A systematic literature search was conducted in December 2014 and repeated in June 2015. Studies that used multivariable analysis to build risk prediction models for falls early after stroke were included. 2 reviewers independently assessed methodological quality. Data relating to model calibration, discrimination (C-statistic) and clinical utility (sensitivity and specificity) were extracted. A narrative review of models was conducted. PROSPERO reference: CRD42014015612. Results The 12 included articles presented 18 risk prediction models. 7 studies predicted falls among inpatients only and 5 recorded falls in the community. Methodological quality was variable. A C-statistic was reported for 7 models and values ranged from 0.62 to 0.87. Models for use in the inpatient setting most frequently included measures of hemi-inattention, while those predicting community events included falls (or near-falls) history and balance measures most commonly. Only 2 studies reported any form of validation, and none presented a validated model with acceptable performance. Conclusions A number of falls-risk prediction models have been developed for use in the acute and subacute stages of stroke. Future research should focus on validating and improving existing models, with reference to the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) guidelines to ensure quality reporting and expedite clinical implementation.

Background There is a paucity of cross-national population-based research on hospitalisations of people at the end of life. We aimed to compare, in four European countries, the frequency, time, length of and factors associated with hospitalisations in the last 3 months of life. Methods Population-based mortality follow-back study via Sentinel Networks of general practitioners (GPs) in Belgium, the Netherlands, Italy and Spain. Using a standardised form, GPs recorded the care in the last 3 months of life of every deceased practice patient (≥18 years; 1 January 2009 to 31 December 2011). Sudden deaths were excluded. Results We studied 4791 deaths that GPs described as non-sudden (66% of all registered deaths). Between 49% (the Netherlands) and 56% (Belgium) of patients were hospitalised at least once in the last 3 months of life. Readmissions were less frequent in the Netherlands (8%) than in the other countries (15-20%, p<0.001). Chances of being hospitalised increased over the last 10 days of life across countries but remained lowest in the Netherlands (Belgium: 21-37%, the Netherlands: 15-29%, Italy: 16-37%, Spain: 14-31%). Hospitalisations in the last week of life were more likely if patients resided at home rather than in a care home (ORs and 95% CIs Belgium: 1.94 (1.28 to 2.94); the Netherlands: 2.61 (1.10 to 6.18); Spain: 4.72 (1.64 to 13.57); non-significant in Italy) and less likely if the GP knew the patient's preferred place of death (ORs and 95% CIs Belgium: 0.52 (0.36 to 0.74); the Netherlands: 0.48 (0.25 to 0.91); Spain: 0.24 (0.13 to 0.44), nonsignificant in Italy). Conclusions The use of hospitals at the end-of-life increased over the last weeks of life of patients in all countries studied, but remained lowest in the Netherlands, as did the rate of readmissions. This may be due to gatekeeping by GPs who are trained and supported in preventing hospital readmissions at the end of life. [ABSTRACT FROM AUTHOR]

Background Adolescent drinking in Western countries has been associated with older age and high socioeconomic status, but the association with family structure was inconsistent. Methods In a 2012-2013 school-based survey in Hong Kong, 23 096 students (mean age 14.7 years, SD 1.8 years) completed an anonymous questionnaire. Current drinking was defined as any drinking and binge drinking as consuming at least 5 drinks on one occasion, both in the past 30 days. Multilevel logistic regression was used to examine the association of sociodemographic characteristics with current drinking, binge drinking and type of alcohol consumed. Results Current drinking was associated with age (≥ vs ≤14 years) (adjusted OR 1.87, 95% CI 1.74 to 2.02), higher perceived family affluence versus low affluence (1.11, 1.02 to 1.21 for medium affluence; 1.55, 1.38 to 1.75 for high affluence), private housing versus public housing (1.11, 1.01 to 1.21) and non-intact family versus intact family (1.31, 1.19 to 1.45 for separated/divorced parents; 1.40, 1.21 to 1.62 for one or both deceased parents). Similar risk factors were observed for binge drinking. Girls were more likely to drink fruit wine (1.48, 1.36 to 1.62), while they were less likely to drink beer (0.85, 0.79 to 0.92) and spirits (0.69, 0.54 to 0.87). Students who reported high family affluence were more likely to drink wine (1.91, 1.59 to 2.30) and spirits (2.23, 1.54 to 3.24). Conclusions Generally, adolescents who were older and had higher socioeconomic status were more likely to drink. High family affluence was associated with wine and spirits drinking. Beer and spirits were preferred more by boys, and fruit wine by girls. These results indicated high-risk groups for adolescent alcohol interventions. [ABSTRACT FROM AUTHOR]

Background Our objectives were to: (1) examine the occurrence of labour induction, caesarean section, and operative vaginal delivery in women with intellectual and developmental disabilities compared to those without and (2) determine whether pre-pregnancy health conditions and pregnancy complications explain any elevated occurrence of these interventions. Methods We conducted a population-based study using linked Ontario (Canada) administrative data. We identified deliveries to women with (N=3932) and without (N=382 774) intellectual and developmental disabilities (2002-2011). Modified Poisson regression was used to estimate adjusted relative risks (aRR) and 95% CIs for interventions, controlling for sociodemographic characteristics. We used generalised estimating equations to determine whether pre-pregnancy health conditions and pregnancy complications explained any statistically significantly elevated aRRs. Results After controlling for socio-demographic characteristics, women with intellectual and developmental disabilities were more likely to have labour inductions (aRR, 1.13; 95% CI 1.06 to 1.20) and caesarean sections (aRR, 1.09; 95% CI 1.03 to 1.16) but not operative vaginal deliveries, compared to the referent group. Pre-pregnancy health conditions explained 12.9% of their elevated aRR for labour induction. Pre-pregnancy health conditions and maternal complications explained 27.8% and 13.3%, respectively, of their elevated aRR for caesarean section. Conclusions Women with intellectual and developmental disabilities are slightly more likely to have labour inductions and caesarean sections than women without intellectual and developmental disabilities. The elevated occurrence of these interventions is not fully explained by their pre-pregnancy health conditions or pregnancy complications. Non-medical issues should be evaluated for their influence on the timing of labour and delivery in this population. [ABSTRACT FROM AUTHOR]

Background Student loans are the second largest source of personal debt in the USA and may represent an important source of financial strain for many young adults. Little attention has been paid to whether debt is associated with sleep duration, an important health-promoting behaviour. We determine if student loans are associated with sleep duration. Since black young adults are more likely to have student debt and sleep less, we also consider whether this association varies by race. Methods Data come from the US National Longitudinal Survey of Youth 1997. The main analytic sample includes 4714 respondents who were ever enrolled in college and who reported on sleep duration in 2010. Most respondents had completed their college education by 2010, when respondents were 25 to 31 years old. Multivariable linear regression models assessed the cross-sectional association between student loans accumulated over the course of college and sleep duration in 2010, as well as between student debt at age 25 and sleep duration in 2010. Results Black young adults with greater amounts of student loans or more student debt reported shorter sleep duration, controlling for occupation, hours worked, household income, parental net worth, marital status, number of children in the household and other sociodemographic and health indicators. There was no association between student loans or debt with sleep for white or latino adults and other racial/ethnic groups. Conclusions Student loans may contribute to racial inequities in sleep duration. Our findings also suggest that the student debt crisis may have important implications for individuals' sleep, specifically and public health, more broadly. [ABSTRACT FROM AUTHOR]

Background A healthy start to life is a major priority in efforts to reduce health inequalities across Europe, with important implications for the health of future generations. There is limited combined evidence on inequalities in health among newborns across a range of European countries. Methods Prospective cohort data of 75 296 newborns from 12 European countries were used. Maternal education, preterm and small for gestational age births were determined at baseline along with covariate data. Regression models were estimated within each cohort and meta-analyses were conducted to compare and measure heterogeneity between cohorts. Results Mother's education was linked to an appreciable risk of preterm and small for gestational age (SGA) births across 12 European countries. The excess risk of preterm births associated with low maternal education was 1.48 (1.29 to 1.69) and 1.84 (0.99 to 2.69) in relative and absolute terms (Relative/Slope Index of Inequality, RII/SII) for all cohorts combined. Similar effects were found for SGA births, but absolute inequalities were greater, with an SII score of 3.64 (1.74 to 5.54). Inequalities at birth were strong in the Netherlands, the UK, Sweden and Spain and marginal in other countries studied. Conclusions This study highlights the value of comparative cohort analysis to better understand the relationship between maternal education and markers of fetal growth in different settings across Europe.

Background A recurring concern in traditional and in Web-based studies pertains to non-representativeness due to volunteer bias. We investigated this issue in an ongoing, large population-based e-cohort. Methods The sample included 122 912 individuals enrolled in the Internet-based, nutrition-focused NutriNet-Santé study between May 2009 and March 2014, with complete baseline data. Participants were recruited via recurrent multimedia campaigns and other traditional and online strategies. Individuals aged 18+ years, residing in France and having Internet access, were eligible for enrolment. Their sociodemographic characteristics were compared with the corresponding 2009 Census data via χ2 goodness-of-fit tests. The effectiveness of statistical weighting of the e-cohort data was also explored. Results The sample exhibited marked geographical and sociodemographic diversity, including volunteers belonging to typically under-represented subgroups in traditional surveys (unemployed, immigrants, the elderly). Nonetheless, the proportions of women, relatively welleducated individuals and those who are married or cohabiting, were notably larger compared with the corresponding national figures (women: 78.0% vs 52.4%; postsecondary education: 61.5% vs 24.9%; married or cohabiting: 70.8% vs 62.0%, respectively; all p<0.0001). Conclusions There were notable sociodemographic differences between the general French population and this general population-based e-cohort, some of which were corrected by statistical weighting. The findings bear on the potential generalisability of future investigations in the context of e-epidemiology. [ABSTRACT FROM AUTHOR]

Background It is widely believed that persons employed in jobs demanding long working hours are at greater risk of physical inactivity than other workers, primarily because they have less leisure time available to undertake physical activity. The aim of this study was to test this hypothesis using prospective data obtained from a nationally representative sample of employed persons. Methods Longitudinal data from the Household, Income and Labour Dynamics in Australia Survey (93 367 observations from 17 893 individuals) were used to estimate conditional fixed effects logistic regression models of the likelihood of moderate or vigorous physical exercise for at least 30 min, at least four times a week. Results No significant associations between long working hours and the incidence of healthy levels of physical activity were uncovered once other exogenous influences on activity levels were controlled for. The odds of men or women who usually work 60 or more hours per week exercising at healthy levels were 6% and 11% less, respectively, than those of comparable persons working a more standard 35-40 h/week; however, neither estimate was significantly different from 0 at 95% CI. Conclusions The findings suggest that there is no trade-off between long working hours and physical activity in Australia. It is argued that these findings are broadly consistent with previous research studies from Anglo-Saxon countries (where long working hours are pervasive) that employed large nationally representative samples.

Background In prior studies, lifestyle indices were associated with numerous disease end points, but the association with fatty liver disease (FLD), a key correlate of cardiometabolic risk, is unknown. The aim was to investigate associations between a lifestyle index with liver fat content. Methods Liver fat was quantified by MRI as liver signal intensity (LSI) in 354 individuals selected from a population-based cohort from Germany. Exposure to favourable lifestyle factors was quantified using an additive score with each factor modelled as a dichotomous trait. Favourable lifestyle factors were defined as waist circumference below 102 (men) or 88 cm (women), physical activity ≥3.5 h/week, never-smoking and a favourable dietary pattern, which was derived to explain liver fat variation. In a cross-sectional study, multivariable adjusted linear and logistic regression was applied to investigate the association between the lifestyle index (range 0-4, exposure) and LSI (modelled as a continuous trait or dichotomised as a FLD indicator variable, respectively). Results Individuals with four favourable lifestyle factors (n=9%) had lower LSI values (β -0.40; 95% CI -0.61 to -0.19) and a lower OR (0.09; 95% CI 0.03 to 0.30) for FLD compared with individuals with zero favourable lifestyle factors (n=10%). Conclusions A healthy lifestyle pattern was associated with less liver fat. Prospective studies are warranted. [ABSTRACT FROM AUTHOR]

Background Active commuting is associated with various health benefits, but little is known about its causal relationship with body mass index (BMI). Methods We used cohort data from three consecutive annual waves of the British Household Panel Survey, a longitudinal study of nationally representative households, in 2004/2005 (n=15 791), 2005/2006 and 2006/2007. Participants selected for the analyses (n=4056) reported their usual main mode of travel to work at each time point. Self-reported height and weight were used to derive BMI at baseline and after 2 years. Multivariable linear regression analyses were used to assess associations between switching to and from active modes of travel (over 1 and 2 years) and change in BMI (over 2 years) and to assess dose-response relationships. Results After adjustment for socioeconomic and health-related covariates, the first analysis (n=3269) showed that switching from private motor transport to active travel or public transport (n=179) was associated with a significant reduction in BMI compared with continued private motor vehicle use (n=3090; -0.32 kg/m², 95% CI -0.60 to -0.05). Larger adjusted effect sizes were associated with switching to active travel (n=109; -0.45 kg/m², -0.78 to -0.11), particularly among those who switched within the first year and those with the longest journeys. The second analysis (n=787) showed that switching from active travel or public transport to private motor transport was associated with a significant increase in BMI (0.34 kg/m², 0.05 to 0.64). Conclusions Interventions to enable commuters to switch from private motor transport to more active modes of travel could contribute to reducing population mean BMI. [ABSTRACT FROM AUTHOR]

Background The English NHS Bowel Cancer Screening Programme has offered biennial faecal occult blood testing to people aged 60-69 years since 2006, and to those aged 60-74 years since 2010. Analysis of the first 2.6 million screening invitations found that 54% of eligible people took up the invitation. The reasons for this low uptake are unclear. We investigated whether participation in screening varies according to cognitive ability and personality. Methods Participants were members of The English Longitudinal Study of Ageing. In 2010-2011, respondents were asked about participation in bowel cancer screening, and cognitive ability and the ‘Big Five’ personality traits were assessed. Logistic regression was used to examine the cross-sectional relationships between cognitive ability and personality and screening participation in 2681 people aged 60-75 years who were eligible to have been invited to take part in the UK national screening programme for bowel cancer. Results In age-adjusted and sex-adjusted analyses, better cognition and higher conscientiousness were associated with increased participation in cancer screening. ORs (95% CIs) per SD increase were 1.10 (1.03 to 1.18) for cognitive ability and 1.10 (1.01 to 1.19) for conscientiousness. After further adjustment for household wealth and health literacy—shown previously to be associated with participation—these associations were attenuated (ORs were 1.07 (1.00 to 1.15) and 1.07 (0.97 to 1.18), respectively). Conclusions We found some indication that better cognitive function and greater conscientiousness may be linked with a slightly increased likelihood of participation in bowel cancer screening. These relationships need investigation in other cohorts of older people. [ABSTRACT FROM AUTHOR]

Background: An emerging literature shows that mortgage strain can lead to poor health outcomes, but less work has focused on whether and how health shocks influence mortgage distress. We examine the link between changes in health status and default/foreclosure risk among older middle-aged adults. Method: We used National Longitudinal Study of Youth 1979 data and multivariate logistic regression models to examine the relationship between changes in health limitations and chronic conditions across survey waves and risk of mortgage default and foreclosure. Results: We found that changes in health limitations and chronic conditions increased the risk of default and foreclosure between 2007 and 2010. These associations were partially mediated by changes in family income and loss of health insurance. Conclusions: From a policy perspective, the strong link between the onset of illness and foreclosure suggests a need to re-examine the safety-nets that are available to individuals who become ill or disabled.

Background Tobacco smoke pollution (TSP) has major negative effects on infant health. Our objectives were to determine the effectiveness of a brief primary care intervention directed at parents who smoke in reducing babies’ TSP exposure, and to establish variables related to greater exposure. Method A multicentre, open, cluster-randomised clinical trial in Catalonia. The 83 participating primary health paediatric teams of the Catalan Health Service recruited 1101 babies whose parents were smokers. The intervention group (IG) received a brief TSP intervention; the control group (CG) received the usual care. Outcomes were measured by parents’ reported strategies to avoid TSP exposure. Baseline clinical data and characteristics of each baby’s TSP exposure were collected, along with infant hair samples and parents’ tobacco use and related attitudes/behaviours. At 3-month and 6-month follow-up, behavioural changes to avoid TSP exposure were recorded; the association between reported parental behaviours and nicotine concentration in infant hair samples was tested in a random sample of 253 babies at baseline and 6 months. Results During follow-up, TSP-avoidance strategies improved more in the IG than in the CG: 35.4% and 26.9% ( p=0.006) at home, and 62.2% and 53.1% in cars (p=0.008). Logistic regression showed adjusted ORs for appropriate measures in the IG versus CG of 1.59 (95% CI 1.21 to 2.09) at home and 1.30 (95% CI 0.97 to 1.75) in cars. Hair samples showed that 78.7% of the babies tested were exposed. Reduced nicotine concentration was associated with improved implementation of effective strategies reported by parents at home (p=0.029) and in cars (p=0.014). Conclusions The intervention produced behavioural changes to avoid TSP exposure in babies. The proportion of babies with nicotine (>=1ng/mg) in hair samples at baseline is a concern.

Background Health literacy skills tend to decline during ageing, which is often attributed to age-related cognitive decline. Whether health literacy skills may be influenced by technological and social factors during ageing is unknown. Methods We investigated whether internet use and social engagement protect against health literacy decline during ageing, independent of cognitive decline. We used prospective data from 4368 men and women aged ≥52 years in the English Longitudinal Study of Ageing from 2004 to 2011. Health literacy was measured at baseline (2004–2005) and at follow-up (2010–2011) using a reading comprehension test of a fictitious medicine label. The influences of consistent internet use and engagement in each of the civic, leisure and cultural activities on health literacy decline over the follow-up were estimated. Results After adjusting for cognitive decline and other covariates, consistent internet use (1379/4368; 32%) was protectively associated with health literacy decline (OR=0.77; 95% CI 0.60 to 0.99), as was consistent engagement in cultural activities (1715/4368; 39%; OR=0.73; 95% CI 0.56 to 0.93). As the number of activities engaged in increased, the likelihood of health literacy decline steadily decreased (ptrend<0.0001), with OR=0.51 (95% CI 0.33 to 0.79) for engaging in all four of the internet use and civic, leisure and cultural activities versus none. Conclusions Internet use and social engagement, particularly in cultural activities (eg, attending the cinema, art galleries, museums and the theatre), may help older adults to maintain health literacy during ageing. Support for older adults to maintain socially engaged lives and to access the internet should help promote the maintenance of functional literacy skills during ageing. [ABSTRACT FROM AUTHOR]

Background There is a paucity of data on the national population-level effectiveness of preventing mother-to-child transmission (PMTCT) programmes in high-HIV-prevalence, resource-limited settings. We assessed national PMTCT impact in South Africa (SA), 2010. Methods A facility-based survey was conducted using a stratified multistage, cluster sampling design. A nationally representative sample of 10 178 infants aged 4–8 weeks was recruited from 565 clinics. Data collection included caregiver interviews, record reviews and infant dried blood spots to identify HIV-exposed infants (HEI) and HIV-infected infants. During analysis, self-reported antiretroviral (ARV) use was categorised: 1a: triple ARV treatment; 1b: azidothymidine >10 weeks; 2a: azidothymidine ≤10 weeks; 2b: incomplete ARV prophylaxis; 3a: no antenatal ARV and 3b: missing ARV information. Findings were adjusted for non-response, survey design and weighted for live-birth distributions. Results Nationally, 32% of live infants were HEI; early mother-to-child transmission (MTCT) was 3.5% (95% CI 2.9% to 4.1%). In total 29.4% HEI were born to mothers on triple ARV treatment (category 1a) 55.6% on prophylaxis (1b, 2a, 2b), 9.5% received no antenatal ARV (3a) and 5.5% had missing ARV information (3b). Controlling for other factors groups, 1b and 2a had similar MTCT to 1a (Ref; adjusted OR (AOR) for 1b, 0.98, 0.52 to 1.83; and 2a, 1.31, 0.69 to 2.48). MTCT was higher in group 2b (AOR 3.68, 1.69 to 7.97). Within group 3a, early MTCT was highest among breastfeeding mothers 11.50% (4.67% to 18.33%) for exclusive breast feeding, 11.90% (7.45% to 16.35%) for mixed breast feeding, and 3.45% (0.53% to 6.35%) for no breast feeding). Antiretroviral therapy or >10 weeks prophylaxis negated this difference (MTCT 3.94%, 1.98% to 5.90%; 2.07%, 0.55% to 3.60% and 2.11%, 1.28% to 2.95%, respectively). Conclusions SA, a high-HIV-prevalence middle income country achieved <5% MTCT by 4–8 weeks post partum. The long-term impact on PMTCT on HIV-free survival needs urgent assessment [ABSTRACT FROM AUTHOR]

Background: Teenage pregnancy is a known social problem which has been previously described using a number of deprivation measures. This study aimed to explore the temporal patterns of teenage pregnancy in Aberdeen, Scotland and to assess the discriminating ability of three measures of socioeconomic status. Methods: This was a population-based study from 1950 to 2010, using data from the Aberdeen Maternity Neonatal Databank (AMND). The main outcome variable was conceptions occurring in women aged less than 20 years. This study used two area-based measures, the Scottish Index of Multiple Deprivation (SIMD) and the Carstairs index, and one individual-based measure the Social Class based on Occupation (SCO). These measures were compared for their association with teenage conceptions using logistic regression models. The models were used to determine receiver operating characteristic (ROC) curves showing the discriminating ability of the measures. Results: There was an overall decline in teenage conceptions over the 60-year period, but an increase in the rate ratio for deprived areas. All the measures of socioeconomic status were highly associated with teenage pregnancy. The adjusted OR of SIMD and teenage conception was 5.72 (95% CI 4.62 to 7.09), which compared the most deprived decile with the least deprived decile. The use of ROC curves showed that socioeconomic measures performed better than chance at determining teenage conceptions (χ2=21.67, p≤0.0001). They further showed that the SIMD had the largest area under the curve (AUC) with a value of 0.81 (95% CI 0.80 to 0.82), followed by the Carstairs index with an AUC of 0.80 (95% CI 0.78 to 0.80), then by SCO with an AUC of 0.79 (95% CI 0.78 to 0.80). Conclusions: Despite a slight decline in teenage pregnancies over the past decades, there is still an evident association between deprivation and teenage pregnancy. This study shows that all the measures of socioeconomic status were highly associated with teenage pregnancy, with the SIMD having the greatest discriminatory effect. [ABSTRACT FROM AUTHOR]

Background Accumulating evidence suggests that television (TV) viewing is associated with cardiometabolic risk, but little is known about how this relationship unfolds over the life course. This study employs a life course epidemiological framework by examining the potential cumulative effect of frequent TV viewing during adolescence and young adulthood on the prevalence of metabolic syndrome in mid-adulthood; and whether TV viewing during adolescence constitutes a sensitive period for the development of the metabolic syndrome in mid-adulthood. Methods We used data from the Northern Swedish Cohort, a nationally representative cohort comprising 855 participants (80% of the baseline sample). Data were collected during 1981–2008 and analysed in 2013. Logistic regression was applied to examine the associations between TV viewing at ages 16, 21 and 30 years, and the metabolic syndrome at age 43 years. Results Cumulative frequent TV viewing was associated with subsequent prevalence of the metabolic syndrome after adjustment for potential confounders (p for trend=0.026). Watching ‘several shows a day’ compared with ‘one show/week’ or less at age 16 years was associated with the metabolic syndrome at age 43 years after adjustment for later exposure (TV viewing at ages 21 and 30 years) and potential confounders (OR 1.86, 95% CI 1.06 to 3.27). Conclusions The number of life periods of frequent TV viewing during adolescence and early adulthood influenced cardio-metabolic risk in mid-adulthood in a dose-dependent manner, corresponding to a cumulative risk life course model. Additionally, TV viewing in adolescence may constitute a sensitive period for the metabolic syndrome in mid-adulthood. [ABSTRACT FROM AUTHOR]

Background Retirement is associated with an increase in recreational physical activity but its impact on other domains of activity (at home, for transport) and sedentary behaviour, such as time spent watching television (TV) is unknown. We examined the association between retirement and changes in domain-specific and overall activity and TV viewing. Methods Data were derived from the population-based EPIC (European Prospective Investigation into Cancer)– Norfolk cohort. Physical activity and TV viewing time were self-reported at baseline (1997–2000) and followup 2 (2006–2007) by 3334 participants employed at baseline, of whom 785 (24%) were retired at follow-up 1 (2002–2006). Multivariable regression models were fitted to estimate the association between retirement and changes in physical activity and weekly TV viewing time. Results Compared with continued employment, retirement was associated with a decline in overall activity (men: non-manual, −40.9 MET h/wk; manual, −49.6 MET h/wk; women: non-manual, −26.9 MET h/wk; manual, −31.6 MET h/wk; all p<0.001 (MET, metabolic equivalent of task)). Domain-specific activity declined for transport and occupational (p<0.001) and increased for recreational (p<0.02) and household (p≤0.002) activity. We observed significant interaction between retirement and social class in respect of overall and domain-specific activity apart from household activity. Retirement was associated with a mean increase in TV viewing time, with the largest increase among manual social classes (men: +3.9 h/wk; women: +2.8 h/wk; both p<0.001). Conclusions Interventions should aim to promote household and transport as well as recreational activity. Further research on the impact of retirement on sedentary behaviour is needed.

Background Since the 1930s, the environment has become increasingly obesogenic, leading to rising rates of adiposity and socioeconomic inequalities in adiposity. Building on studies comparing body mass index (BMI) for cohorts born over a period of 20 years, we examine the social patterning of BMI and central adiposity for three cohorts born over a 40-year period. Methods Using data from the West of Scotland Twenty-07 study (n=4510), we investigate 20-year trajectories of adiposity for three cohorts born in the 1930s, 1950s and 1970s, allowing us to study 60 years of the lifecourse. Stratified by gender, we employed multilevel models to generate trajectories for BMI and waist-to-height ratio (WHtR) and explored how these trajectories varied by childhood social class. Results Adiposity increased most quickly with age in the youngest cohort, and cohort differences were greater than socioeconomic differences. For example, the smallest cohort difference for BMI, a comparison of men in the 1930s and 1950s cohorts at age 55, was 2.66 (95% CI 2.11 to 3.20) kg/m2, while the largest socioeconomic difference, a comparison of manual and non-manual women at age 64, was 1.18 (95% CI 0.37 to 1.98) kg/ m2. Socioeconomic inequalities in adiposity increased with age and were greater for women than for men. The results for WHtR differed in that increases in WHtR accelerated with age while increases in BMI slowed. Conclusions Socioeconomic differences in adiposity accumulate slowly across the lifecourse and are approximately only a third of the adiposity differences between cohorts. [ABSTRACT FROM AUTHOR]

Background The purpose of this study is to determine the prevalence of diabetes distress and its relationship with health behaviours and clinical outcomes in low-income patients. Methods Secondary analyses were conducted using baseline data from a clinical trial evaluating a diabetes self-management intervention. Interviews were conducted with 666 participants receiving care at nine safety net clinics in Missouri. Distress was measured using the Diabetes Distress Scale, and outcomes included medication adherence, physical activity, nutrition and clinical biomarkers (haemoglobin A1C (HbA1C), blood pressure, low-density lipoprotein (LDL) cholesterol). Results In a sample of 666 participants, 14.1% and 27.3% of patients were identified as highly and moderately distressed, respectively, with higher rates among younger, female and lower income patients. When compared with moderately and no distress groups, highly distressed patients were less adherent to medications (20.7% vs 29.9% vs 39.4%, p<0.001) and had higher HbA1C values (9.3% (SD=2.0) vs 8.2% (SD=1.8) vs 7.8% (SD=1.7), p<0.001), diastolic blood pressure (81.8 (SD=9.4) vs 80.2 (9.7) vs 78.9 (SD=8.8), p=0.02) and LDL cholesterol (104.6 (SD=42.4) vs 97.2 (34.3) vs 95.5 (37.9)) In multivariable analyses, high and moderate distress were associated with lower medication adherence (OR=0.44; 0.27 to 0.23, p=0.001) and (OR=0.58; 0.42 to 0.79; p=0.001), respectively, and higher HbA1C in only the highly distressed group (B=1.3; 0.81 to 1.85; p<0.001) compared with the no distress group. Conclusions Diabetes distress is prevalent and linked to poorer adherence to health behaviours and glycemic control in a sample of patients receiving care from low-income clinics.

Background Mobility-related fatigue and low socioeconomic position predicts mobility limitations and disability in old age, but the interplay between these two factors is unknown. To evaluate whether mobility-related fatigue is a stronger risk factor for mobility limitations in certain socioeconomic groups, the aim of this study was to examine the combined effect of mobility-related fatigue and socioeconomic position on mobility limitations in a prospective study among older Danish men and women. Methods Multivariate linear regression models with combined exposure variables using generalised estimating equations were performed using four waves of data on 2874 individuals without mobility limitations at baseline from The Danish Intervention Study on Preventive Home Visits. Results Low socioeconomic position and mobility-related fatigue are risk factors for mobility limitations in old age. The combined exposure to both factors additionally increased the risk, but there was no synergy effect between the two. Notably, fatigue predicted mobility decline at 3-year follow-up among those aged 80 years at baseline with a mean difference in number of mobility limitations from the joint reference category (high socioeconomic position and no fatigue) of ?0.52, p<0.0001 among those in high socioeconomic position and ?0.96, p<0.0001 among those in low socioeconomic position. Conclusions Mobility-related fatigue is not a significantly stronger risk factor for subsequent mobility limitations among those with concomitant exposure to low socioeconomic position, compared with those with high socioeconomic position. Preventive strategies must focus on vulnerable groups of older people with low socioeconomic position as well as on individuals with fatigue. [ABSTRACT FROM AUTHOR]
