OBJECTIVE: To provide a current estimate of the prevalence of prepregnancy obesity in the United States. METHODS: We analyzed 2004-2005 data from 26 states and New York City (n = 75,403 women) participating in the Pregnancy Risk Assessment Monitoring System, an ongoing, population-based surveillance system that collects information on maternal behaviors associated with pregnancy. Information was obtained from questionnaires self-administered after delivery or from linked birth certificates; prepregnancy body mass index was based on self-reported weight and height. Data were weighted to provide representative estimates of all women delivering a live birth in each particular state. RESULTS: In this study, about one in five women who delivered were obese; in some state, race/ethnicity, and Medicaid status subgroups, the prevalence was as high as one-third. State-specific prevalence varied widely and ranged from 13.9 to 25.1%. Black women had an obesity prevalence about 70% higher than white and Hispanic women (black: 29.1%; white: 17.4%; Hispanic: 17.4%); however, these race-specific rates varied notably by location. Obesity prevalence was 50% higher among women whose delivery was paid for by Medicaid than by other means (e.g., private insurance, cash, HMO). CONCLUSION: This prevalence makes maternal obesity and its resulting maternal morbidities (e.g., gestational diabetes mellitus) a common risk factor for a complicated pregnancy.

Background: The Women's Health Needs Study (WHNS) collected information on the health characteristics, needs, and experiences, including female genital mutilation (FGM) experiences, attitudes, and beliefs, of women aged 18 to 49 years who were born, or whose mothers were born, in a country where FGM is prevalent living in the US. The purpose of this paper is to describe the WHNS design, methods, strengths and limitations, as well as select demographic and health-related characteristics of participants., Methods: We conducted a cross-sectional survey from November 2020 -June 2021 in four US metropolitan areas, using a hybrid venue-based sampling (VBS) and respondent-driven sampling (RDS) approach to identify women for recruitment., Results: Of 1,132 participants, 395 were recruited via VBS and 737 RDS. Most were born, or their mothers were born, in either a West African country (Burkina Faso, Guinea, Mali, Mauritania, Sierra Leone, The Gambia) (39.0%) or Ethiopia (30.7%). More than a third were aged 30-39 years (37.5%) with a majority who immigrated at ages ≥13 years (86.6%) and had lived in the United States for ≥5 years (68.9%). Medicaid was the top health insurer (52.5%), followed by private health insurance (30.5%); 17% of participants had no insurance. Nearly half of women reported 1-2 healthcare visits within the past 12 months (47.7%). One in seven did not get needed health care due to cost (14.8%). Over half have ever used contraception (52.1%) to delay or avoid pregnancy and 76.9% had their last pelvic and/or Papanicolaou (pap) exam within the past 3 years. More than half experienced FGM (55.0%). Nearly all women believed that FGM should be stopped (92.0%)., Conclusion: The VBS/RDS approach enabled recruitment of a diverse study population. WHNS advances research related to the health characteristics, needs, and experiences of women living in the US from countries where FGM is prevalent., Competing Interests: The authors have declared that no competing interests exist., (Copyright: This is an open access article, free of all copyright, and may be freely reproduced, distributed, transmitted, modified, built upon, or otherwise used by anyone for any lawful purpose.

Introduction: Postpartum depression is a serious public health problem that can adversely impact mother-child interactions. Few studies have examined depressive symptoms in the later (9-10 months) postpartum period., Methods: We analyzed data from the 2019 Pregnancy Risk Assessment Monitoring System (PRAMS) linked with data from a telephone follow-up survey administered to PRAMS respondents 9 to 10 months postpartum in 7 states (N = 1,954). We estimated the prevalence of postpartum depressive symptoms (PDS) at 9 to 10 months overall and by sociodemographic characteristics, prior depression (before or during pregnancy), PDS at 2 to 6 months, and other mental health characteristics. We used unadjusted prevalence ratios (PRs) to examine associations between those characteristics and PDS at 9 to 10 months. We also examined prevalence and associations with PDS at both time periods., Results: Prevalence of PDS at 9 to 10 months was 7.2%. Of those with PDS at 9 to 10 months, 57.4% had not reported depressive symptoms at 2 to 6 months. Prevalence of PDS at 9 to 10 months was associated with having Medicaid insurance postpartum (PR = 2.34; P = .001), prior depression (PR = 4.03; P <.001), and current postpartum anxiety (PR = 3.58; P <.001). Prevalence of PDS at both time periods was 3.1%. Of those with PDS at both time periods, 68.5% had prior depression., Conclusion: Nearly 3 in 5 women with PDS at 9 to 10 months did not report PDS at 2 to 6 months. Screening for depression throughout the first postpartum year can identify women who are not symptomatic early in the postpartum period but later develop symptoms.

Background: The prevalence and severity of disasters triggered by natural hazards has increased over the last 20 years. Women of reproductive age may encounter unique reproductive health challenges following a disaster. In this scoping review we identify gaps in literature to inform future research and search for potential associations between disasters by natural hazards and post-disaster fertility and contraception among women of reproductive age., Methods: Medline (OVID), Embase (OVID), PsycInfo (OVID), CINAHL (Ebsco), Scopus, Environmental Science Collection (ProQuest Central), and Sociological Abstracts (ProQuest Central) were searched for articles published from 1980 through March 3, 2022 in English or Spanish language. Search terms were related to fertility, contraception, and disasters. We included original research that described a discrete natural hazard exposure, a population of women of reproductive age (15-49 years), and outcomes of fertility or contraception use or access, with pre- and post-disaster measures., Results: Among 9788 citations, after initial exclusion 5121 remained for title and abstract review. One hundred and eighteen citations underwent full-text review and 26 articles met the inclusion criteria. Following critical appraisal, 20 articles were included in this review. Eighteen articles described outcomes related to fertility, five articles described contraception access, and three articles described contraception use., Conclusions: Clearly defined exposure measures, robust analyses, and methodical post-disaster assessment periods, may address the current gaps within disaster research on fertility and contraception among women of reproductive age. Consistent patterns in fertility following a disaster triggered by natural hazards were not identified between or within disaster types. Studies that assessed contraception found no change in use, while some studies found a decrease in contraceptive access overall., (© 2022. US government.)

This report provides historical context and rationale for coordinated, systematic, and evidence-based public health emergency preparedness and response (EPR) activities to address the needs of women of reproductive age. Needs of pregnant and postpartum women, and infants-before, during, and after public health emergencies-are highlighted. Four focus areas and related activities are described: (1) public health science; (2) clinical guidance; (3) partnerships, communication, and outreach; and (4) workforce development. Finally, the report summarizes major activities of the Division of Reproductive Health's EPR Team at the Centers for Disease Control and Prevention.

Introduction: The Delta Regional Authority (DRA) consists of 252 counties and parishes in 8 states in the US Mississippi Delta region. DRA areas have high rates of disease, including cancers related to the human papillomavirus (HPV). HPV vaccination coverage in the DRA region has not been documented., Methods: We analyzed data for 63,299 adolescents aged 13 to 17 years in the National Immunization Survey-Teen, 2015-2017. We compared HPV vaccination initiation coverage estimates (≥1 dose) in the DRA region with coverage estimates in areas in the 8 Delta states outside the DRA region and non-Delta states. We examined correlates of HPV vaccination coverage initiation and reasons parents did not intend to vaccinate adolescents., Results: Vaccination rates in the DRA region (n = 2,317; 54.3%) and in Delta areas outside the DRA region (n = 6,028; 56.2%) were similar, but these rates were significantly lower than rates in non-Delta states (n = 54,954; 61.4%). Inside the DRA region, reasons for parents' vaccine hesitancy or refusal were similar to those expressed by parents in the Delta areas outside the DRA region. Some parents believed that the vaccine was not necessary or had concerns about vaccine safety., Conclusion: HPV vaccination coverage in the DRA region is similar to coverage in other Delta counties and parishes, but it is significantly lower than in non-Delta states. Activities to address parental concerns and improve provider recommendations for the vaccine in the DRA region are needed to increase HPV vaccination rates.

Background: The Centers for Disease Control and Prevention's Prevention Research Centers (PRC) Program supports community engagement and partnerships to translate health evidence into practice. Translation is dependent on the quality of partnerships. However, questions remain about the necessary characteristics to develop and maintain translation partnerships. Aim: To identify the characteristics that influence community-university partnerships and examine alignment with the Knowledge to Action (K2A) Framework. Methods: Final Progress Reports ( N = 37) from PRCs funded from September 2009 to September 2014 were reviewed in 2016-2017 to determine eligibility. Eligible PRCs included those that translated an innovation following the applied research phase (2009-2014) of the PRC award ( n = 12). The PRCs and the adopters (i.e., community organizations) were recruited and participated in qualitative interviews in 2017. Results: Ten PRCs (83.3% response rate) and four adopters participated. Twelve codes (i.e., elements) were found that impacted partnerships along the translation continuum (e.g., adequate communication, technical assistance). Each element aligned with the K2A Framework at multiple steps within the translation phase. The intersection between the element and step in the translation phase is termed a "characteristic." Using interview data, fifty-two unique partnership characteristics for translation were found. Discussion and Conclusion: The results suggest multiple characteristics that impact translation partnerships. The inclusion of these partnership characteristics in policies and practices that seek to move practice-based or research-based evidence into widespread use may impact the receptivity by partners and evidence uptake by communities. Using the K2A Framework to assess translation partnerships was helpful and could be considered in process evaluations to inform translation partnership improvement., (Copyright © 2020 Young, Leeks, Bish, Mihas, Marcelin, Kline and Ulin.)

Objectives: To estimate the economic value from a societal perspective of informal caregiving of persons with dementia in 38 states, the District of Columbia, and Puerto Rico., Methods: Using a cost replacement method and data from the 2015 and 2016 Behavioral Risk Factor Surveillance System caregiver module, the US Bureau of Labor Statistics May 2016 Occupation Profiles, and the US Department of Labor, we estimated the number and economic direct cost of caregiving hours., Results: An estimated 3.2 million dementia caregivers provided more than 4.1 billion hours of care, with an average of 1278 hours per caregiver. The median hourly value of dementia caregiving was $10.28. Overall, we valued these caregiving hours at $41.5 billion, with an average of $13 069 per caregiver., Conclusions: Caregivers of persons with dementia provide care that has important economic implications. Without these efforts, many people would either not receive needed care or have to pay for that support. Surveillance data can be used to estimate the contributions of informal caregivers and the economic value of the care they provide.

The 2014-2019 Prevention Research Centers (PRC) Program Funding Opportunity Announcement stated that "all applicants will be expected to collaborate with CDC to collect data to be able to perform cost analysis." For the first time in the 30-year history of the PRC Program, a cost indicator was included in the PRC Program Evaluation and a cost analysis (CA) instrument developed. The PRC-CA instrument systematically collects data on the cost of the PRC core research project to eventually answer the CDC PRC Program Evaluation question: "To what extent do investments in PRCs support the scalability, sustainability, and effectiveness of the outcomes resulting from community-engaged efforts to improve public health?" The objective of this article is to briefly describe the development of the PRC-CA instrument. Data obtained from the PRC-CA instrument can be used to generate cost summaries to inform decision making within the PRC Program and each individual PRC.

Background: Little empirical evidence exists on the effectiveness of using Twitter as a two-way communication tool for public health practice, such as Twitter chats., Objective: We analyzed whether Twitter chats facilitate engagement in two-way communications between public health entities and their audience. We also describe how to measure two-way communications, incoming and outgoing mentions, between users in a protocol using free and publicly available tools (Symplur, OpenRefine, and Gephi)., Methods: We used a mixed-methods approach, social network analysis, and content analysis. The study population comprised individuals and organizations participating or who were mentioned in the first #LiveFitNOLA chat, during a 75-min period on March 5, 2015, from 12:00 PM to 1:15 PM Central Time. We assessed audience engagement in two-way communications with two metrics: engagement ratio and return on engagement (ROE)., Results: The #LiveFitNOLA chat had 744 tweets and 66 participants with an average of 11 tweets per participant. The resulting network had 134 network members and 474 engagements. The engagement ratios and ROEs for the #LiveFitNOLA organizers were 1:1, 40% (13/32) (@TulanePRC) and 2:1, -40% (-25/63) (@FitNOLA). Content analysis showed information sharing (63.9%, 314/491) and health information (27.9%, 137/491) as the most salient theme and sub-theme, respectively., Conclusions: Our findings suggest Twitter chats facilitate audience engagement in two-way communications between public health entities and their audience. The #LiveFitNOLA organizers' engagement ratios and ROEs indicated a moderate level of engagement with their audience. The practical significance of the engagement ratio and ROE depends on the audience, context, scope, scale, and goal of a Twitter chat or other organized hashtag-based communications on Twitter., (©Kristina M Rabarison, Merriah A Croston, Naomi K Englar, Connie L Bish, Shelbi M Flynn, Carolyn C Johnson.

Contemporary public health professionals must address the health needs of a diverse population with constrained budgets and shrinking funds. Economic evaluation contributes to evidence-based decision making by helping the public health community identify, measure, and compare activities with the necessary impact, scalability, and sustainability to optimize population health. Asking "how do investments in public health strategies influence or offset the need for downstream spending on medical care and/or social services?" is important when making decisions about resource allocation and scaling of interventions.

Background: Cervical cancer places a substantial economic burden on our healthcare system. The three-dose human papillomavirus (HPV) vaccine series is a cost-effective intervention to prevent HPV infection and resultant cervical cancer. Despite its efficacy, completion rates are low in young women aged 18 through 26 years. 1-2-3 Pap is a video intervention tested and proven to increase HPV vaccination completion rates., Purpose: To provide the full scope of available evidence for 1-2-3 Pap, this study adds economic evidence to the intervention's efficacy. This study tested the economies of scale hypothesis that the cost of 1-2-3 Pap intervention per number of completed HPV vaccine series would decrease when offered to more women in the target population., Methods: Using cost and efficacy data from the Rural Cancer Prevention Center, a cost analysis was done through a hypothetical adaptation scenario in rural Kentucky., Results: Assuming the same success rate as in the efficacy study, the 1-2-3 Pap adaptation scenario would cover 1000 additional women aged 18 through 26 years (344 in efficacy study; 1346 in adaptation scenario), and almost three times as many completed series (130 in efficacy study; 412 in adaptation scenario) as in the original 1-2-3 Pap efficacy study., Implications: Determination of the costs of implementing 1-2-3 Pap is vital for program expansion. This study provides practitioners and decision makers with objective measures for scalability.

Purpose: We examined the extent to which mental distress may be associated with a woman's preconception health., Methods: We analyzed population-based, self-reported data from the 2005, 2007, and 2009 Behavioral Risk Factor Surveillance System (BRFSS) and limited analyses to 213,137 women aged 18-44 years. Women whose mental health was not good for ≥14 days during the past month were categorized as having frequent mental distress. For 15 preconception health indicators, we used chi-square tests to measure differences in prevalence by mental distress and the average marginal predictions approach to logistic regression to assess associations between mental distress and each preconception health indicator in separate models, adjusted for demographic characteristics. We conducted analyses using SUDAAN software to account for the complex sampling design and used weights to produce unbiased estimates., Results: The prevalence of good preconception health for each indicator was higher for women reporting infrequent mental distress (chi-square p value<0.001 for all). The greatest disparities in preconception health between women with infrequent and frequent mental distress, respectively, were adequate social and emotional support (adjusted prevalence ratio [aPR]=1.4, prevalence=83.7% and 54.8%), not smoking (aPR=1.2, 82.3% and 62.4%), adequate fruit and vegetable consumption (aPR=1.2, 26.1% and 21.5%), normal weight (aPR=1.2, 50.4% and 39.0%), and good general health (aPR=1.2, 91.7% and 71.5%)., Conclusions: Interventions tailored for women with poor mental health may be needed to target specific preconception health indicators, such as social support, smoking, weight, and nutrition.

Objective: We examined the risk of gestational diabetes mellitus (GDM) among foreign-born and U.S.-born mothers by race/ethnicity and BMI category., Design and Method: We used 2004-2007 linked birth certificate and maternal hospital discharge data of live, singleton deliveries in Florida to compare GDM risk among foreign-born and U.S.-born mothers by race/ethnicity and BMI category. We examined maternal BMI and controlled for maternal age, parity, and height., Results: Overall, 22.4% of the women in our study were foreign born. The relative risk (RR) of GDM among women who were overweight or obese (BMI ≥ 25.0 kg m(-2)) was higher than among women with normal BMI (18.5-24.9 kg m(-2)) regardless of nativity, ranging from 1.3 (95% confidence interval (CI) = 1.0, 1.9) to 3.8 (95% CI = 2.1, 7.2).Foreign-born women also had a higher GDM risk than U.S.-born women, with RR ranging from 1.1 (95% CI = 1.1, 1.2) to 2.1 (95% CI = 1.4, 3.1). This finding was independent of BMI, age, parity, and height for all racial/ethnicity groups., Conclusions: Although we found differences in age, parity, and height by nativity, these differences did not substantially reduce the increased risk of GDM among foreign-born mothers. Health practitioners should be aware of and have a better understanding of how race/ethnicity and nativity can affect women with a high risk of GDM. Although BMI is a major risk factor for GDM, it does not appear to be associated with race/ethnicity or nativity., (Copyright © 2012 The Obesity Society.)

Optimal preconception health (PCH) may improve maternal and infant outcomes, priority issues in Mississippi (MS). Our study objective was to compare the PCH of women in the MS Delta to other regions. We analyzed Behavioral Risk Factor Surveillance System data from 2005, 2007, and 2009, and limited analyses to 171,612 non-pregnant black and white women 18-44 years of age. Region was defined as 14 MS Delta counties (MS Delta), remainder of MS (MS non-Delta), Delta states (LA, AR, TN), and non-Delta US states. We calculated adjusted prevalence ratios (aPR) to assess associations between region and 16 indicators of optimal PCH, controlling for demographic characteristics. Healthy PCH factors such as consuming ≥5 fruits and vegetables daily and normal body mass index (18.5 kg/m(2) to <25 kg/m(2)), respectively, were more prevalent in the MS non-Delta (aPR = 1.3; 95 % CI: 1.0,1.7 and aPR = 1.2; 95 % CI: 1.0,1.4), non-MS Delta (aPR = 1.5; 95 % CI: 1.2,2.0 and aPR = 1.3; 95 % CI: 1.1,1.5) and non-Delta states (aPR = 1.7; 95 % CI: 1.3,2.2 and aPR = 1.4; 95 % CI: 1.2,1.6) compared to the MS Delta. Physical activity levels were higher among non-Delta US states compared to the MS Delta (aPR = 1.3; 95 % CI: 1.1,1.4). Household income and race confounded the associations between region and PCH. Reproductive aged women in the MS Delta had poorer PCH, particularly for physical activity and nutrition, than women in other regions. MS Delta service providers and public health practitioners should consider implementing or enhancing lifestyle, nutrition, and physical activity interventions, with a special focus on reducing income-based and racial disparities.

Objective: Current pregnancy weight gain guidelines are based on prepregnancy body mass indices (BMI), but gestational weight gains by BMI class among US women are unknown., Study Design: We assessed the amount of gestational weight gain among 52,988 underweight, normal-weight, overweight, and obese US women who delivered a singleton, full-term infant in 2004-2005. Excessive weight gain during pregnancy was defined as gaining 35 or more pounds for normal-weight and 25 or more pounds for overweight women., Results: Approximately 40% of normal-weight and 60% of overweight women gained excessive weight during pregnancy. Obese women gained the least, although one-fourth of these women gained 35 or more pounds. Excessive weight gain levels were highest among women aged 19-years-old or younger and those having their first birth., Conclusion: Excessive gestational weight gains were common, especially among the youngest and those who were nulliparous. These results predict higher obesity levels from pregnancy weight gains among US women.

Objectives: Current pregnancy weight gain recommendations are for women to gain between 15 and 40 pounds; weight loss or weight maintenance is not recommended. However, for many women, overweight and obesity are chronic conditions, and commitment to weight loss or maintenance could override advice to gain weight during pregnancy. Our objective was to determine the prevalence of trying to lose or maintain weight among U.S. women during pregnancy., Methods: The Behavioral Risk Factor Surveillance System is a state-based, random-digit-dialed telephone survey of noninstitutionalized, U.S. civilians aged > or =18 years. We identified women aged 18-44 years who reported being pregnant during 2003 (n = 2,464), assessed the prevalence of trying to lose or maintain weight and assessed independent associations with selected demographic, clinical, and behavioral factors using multinomial logistic regression., Results: Among women who reported being pregnant, 7.5% (confidence interval [CI] = 5.7-9.8%) and 34.3% (CI = 31.0-37.7%) were trying to lose or maintain weight, respectively. Among women who reported trying to lose or maintain weight, exercise was a more prevalent weight control strategy than dietary change. After adjustment, women who drank alcohol during the past 30 days (Odds ratio [OR] = 8.86, CI: 4.51-17.42) or women who received advice in the past year to lose weight (OR = 9.10, CI: 3.20-25.87) were more likely to report trying to lose weight; women advised to maintain (OR = 0.20, CI: 0.07-0.60) or gain (OR = 0.04, CI: 0.01-0.23) weight were less likely to report trying to lose weight., Conclusions: Despite guidelines to gain weight during pregnancy, about 8% and 34% of U.S. pregnant women reported trying to lose or maintain weight, respectively. Providers may encounter an increasing number of pregnant women whose weight control intentions conflict with current guidelines for pregnancy weight gain. Further research in this area is warranted.

Objective: To examine the prevalence and association of activity/participation limitation with trying to lose weight and weight loss practices (eating fewer calories, physical activity, or both) among overweight and obese adults in the United States., Research Methods and Procedures: Eligible adults were 20 years of age or older with a body mass index (BMI) >or= 25 kg/m(2) (n = 5608) who responded to standard physical functioning questions included in the 1999-2002 National Health and Nutrition Examination Survey, a continuous survey of the civilian non-institutionalized US population., Results: Obese (BMI >or= 30) men with vs. without activity/participation limitations were more likely to try to lose weight (OR = 1.59, 95% CI 1.05-2.41). This was not the case for overweight women and men (BMI 25-29.9), or obese women. Among adults trying to lose weight, reducing calorie consumption was common (63%-73%, men, 67%-76%, women). Overweight women with vs without activity/participation limitations had significantly reduced likelihood of attaining recommended physical activity (OR = 0.56, 95% CI 0.36-0.89). Obese adults were more likely to try to lose weight if they attributed their limitation to body weight (OR = 1.78, 95% CI 1.11-2.88) or diabetes (OR = 1.86, 95% CI 1.01-3.43) compared to other causes. Overweight and obese adults who attributed activity/participation limitations to mental health, musculoskeletal, or cardiovascular problems were equally likely to attempt weight loss when respondents with each condition were compared to respondents without the condition., Discussion: These results verify the importance of adequate subjective health assessment when developing individual weight loss plans, and may help guide weight management professionals in the development and delivery of more personalized care.

Background: Trying to lose weight is a concern for many Americans, but motivation for weight loss is not fully understood. Clinical assessment for obesity treatment is primarily based on measures of body size and physical comorbidities; however, these factors may not be enough to motivate individuals to lose weight. Health-related quality of life (HRQOL) may have a role in an individual's decision to try to lose weight. The objective of this study was to examine the prevalence and association of HRQOL measures as independent moderators of weight loss practices among overweight and obese men and women., Research Methods and Procedures: Data were from the 2003 Behavioral Risk Factor Surveillance System, an annual state-based telephone survey of the civilian noninstitutionalized population of adults 20 years of age or older with BMI > or = 25.0 kg/m2 (n = 111,456) who responded to 4 standard HRQOL measures that assessed general health status, physical health, mental health, and activity limitation in the past 30 days., Results: Among men with BMI 25-34.9 kg/m2, the odds of trying to lose weight increased for the moderate vs best category of HRQOL but not for the poorest vs best category, and no associations were noted for men with BMI > or = 35 kg/m2. Women with BMI 25-34.9 kg/m2 had reduced odds and decreasing associated trends in the prevalence of trying to lose weight with poorer general health, increased physically unhealthy days, and increased activity limitation days. Conversely, women with 1-13 vs 0 mentally unhealthy days had greater odds of trying to lose weight. Among those trying to lose weight, reducing calories was common (52%-69%, men; 56%-69%, women). Among men, with the exception of recent mental health, poorer levels of HRQOL measures were associated with diminished attainment of recommended physical activity levels. Among women, poorer general health status was associated with diminished attainment of recommended physical activity levels., Discussion: With the exception of recent mental health, HRQOL was differentially associated with trying to lose weight among men and women. Specifically, moderately poor HRQOL among men and better HRQOL among women were associated with trying to lose weight. Consideration of these influences on weight loss may be useful in the treatment and support of obese patients.

Objective: To examine the prevalence and association of health-related quality of life (HRQOL) with trying to lose weight and with weight loss practices (eating fewer calories, physical activity, and both) among overweight and obese U.S. adults >/= 20 years of age., Research Methods and Procedures: This study used data from the 2001 to 2002 National Health and Nutrition Examination Survey, a continuous annual survey of the civilian non-institutionalized U.S. population. This analysis included those > or = 20 years of age with BMI > or = 25 (n = 2578) who responded to four standard HRQOL measures that assessed general health status and recent physical health, mental health, and activity limitation., Results: Among obese men, but not women, there were significant increasing linear trends in the adjusted prevalence of trying to lose weight as physically unhealthy and activity limitation days increased. Regardless of BMI or HRQOL, reducing calories was a common weight loss practice (66% to 86%). Except for recent activity limitation, respondents with BMI > or = 35 did not generally differ by HRQOL level in the attainment of recommended physical activity either alone or in combination with reduced calories, whereas those in the BMI 25 to 34.9 groups often differed significantly by HRQOL level. Specifically, increased unhealthy or activity limitation days were associated with reduced prevalence of attained physical activity., Discussion: Our findings indicate an association between trying to lose weight and a greater number of unhealthy days reported by obese men, suggesting that these men may be influenced by traditional clinical weight-loss counseling that is prompted by weight and comorbidity, whereas women had a high prevalence of trying to lose weight irrespective of weight and HRQOL. Assessment of HRQOL, especially measures that evaluate physical domains, could provide subjective information to assist with weight counseling.

Objective: To examine the prevalence and correlates of trying to lose weight among U.S. adults, describe weight loss strategies, and assess attainment of recommendations for weight control (eating fewer calories and physical activity)., Research Methods and Procedures: This study used the Behavioral Risk Factor Surveillance System, a state-based telephone survey of adults > or =18 years of age (N = 184,450) conducted in the 50 states, the District of Columbia, and Puerto Rico in 2000., Results: The prevalence of trying to lose weight was 46% (women) and 33% (men). Women reported trying to lose weight at a lower BMI than did men; 60% of overweight women were trying to lose weight, but men did not reach this level until they were obese. Adults who had a routine physician checkup in the previous year and reported medical advice to lose weight vs. checkup and no medical advice to lose weight had a higher prevalence of trying to lose weight (81% women and 77% men vs. 41% women and 28% men, respectively). The odds of trying to lose weight increased as years of education increased. Among respondents who were trying to lose weight, approximately 19% of women and 22% of men reported using fewer calories and > or =150 min/wk leisure-time physical activity., Discussion: A higher percentage of women than men were trying to lose weight; both sexes used similar weight loss strategies. Education and medical advice to lose weight were strongly associated with trying to lose weight. Most persons trying to lose weight were not using minimum recommended weight loss strategies.

Effects of sequential changes in dietary protein on growth from 0 to 20 weeks of age and on egg production from 20 to 72 weeks of age were evaluated with White Leghorn chickens. Four dietary treatments were compared. They consisted of three dietary regimens wherein an 18% crude protein (CP) diet was fed to 1, 2, or 3 weeks of age (Treatments 1, 2, and 3, respectively) and then common 12, 15, and 18% CP diets to 8, 14, and 20 weeks, respectively. These three regimens were compared with a control regimen (Treatment 4) that consisted of feeding 18, 15, and 12% CP diets to 6, 14, and 20 weeks of age, respectively. At 20 weeks of age, 144 birds from each treatment were moved into laying cages for the subsequent 52 weeks of egg production. In comparison with birds on the control feeding regimen, those reared under Treatments 1, 2, and 3 consumed significantly less feed during the 20-week growing period. Birds of Treatments 2 and 3 consumed significantly more protein than those of Treatments 1 and 4. By feeding a 12% CP diet from 1, 2, and 3 to 8 weeks of age, body weights were significantly lower than the average body weight of the control birds, approximately 20, 17, and 13%, respectively, by 6 weeks of age, but only 2 to 4% at 16 weeks of age, and by nonsignificant amounts at 28 weeks of age. Treatment 1 birds consumed 1.8% (significantly) less feed per unit body weight and were 2.6% (significantly) lighter at 20 weeks of age compared with the control birds.(ABSTRACT TRUNCATED AT 250 WORDS)
