RESUMO
Objective: Obesity in pregnancy and gestational diabetes (GDM) increase cardiometabolic disease risk but are difficult to disentangle. This study aimed to test the hypothesis that 4-10 years after a pregnancy complicated by overweight/obesity and GDM (OB-GDM), women and children would have greater adiposity and poorer cardiometabolic health than those with overweight/obesity (OB) or normal weight (NW) and no GDM during the index pregnancy. Methods: In this cross-sectional study, mother-child dyads were stratified into three groups based on maternal health status during pregnancy (OB-GDM = 67; OB = 76; NW = 76). Weight, height, waist and hip circumferences, and blood pressure were measured, along with fasting glucose, insulin, HbA1c, lipids, adipokines, and cytokines. Results: Women in the OB and OB-GDM groups had greater current adiposity and poorer cardiometabolic health outcomes than those in the NW group (p < 0.05). After adjusting for current adiposity, women in the OB-GDM group had higher HbA1c, glucose, HOMA-IR and triglycerides than NW and OB groups (p < 0.05). Among children, adiposity was greater in the OB-GDM versus NW group (p < 0.05), but other indices of cardiometabolic health did not differ. Conclusions: Poor cardiometabolic health in women with prior GDM is independent of current adiposity. Although greater adiposity among children exposed to GDM is evident at 4-10 years, differences in cardiometabolic health may not emerge until later.
RESUMO
This is the case of an 18-year-old young adult woman with anorexia nervosa (AN) who presented to the emergency department with complications from AN and was found to be hyponatremic. The hyponatremia was prioritized and corrected with fluids on hospital day one. The consulting adolescent medicine team recommended the primary inpatient medical team initiate the malnutrition protocol. Nephrology recommended fluid restriction. Despite initiation of this protocol and emphasis on protocol adherence with the primary team, patient, and family, the hyponatremia recurred. Retrospectively, there were three factors that led to her recurrent hyponatremia: inconsistencies in protocol adherence across medical clinical providers, lack of knowledge regarding the importance of adherence to the malnutrition protocol, and suboptimal communication between medical clinical providers. A multidisciplinary team experienced in the care of patients with AN may enhance inpatient treatment of this condition. A multidisciplinary team experienced in AN will have a better understanding of the complexities of AN, skill in protocol implementation, understand the importance of protocol adherence, and be more likely to clearly communicate the plan of care to the patient/family. These skills can lead to improved care quality, decreased risk of adverse outcomes, and likely decreased medical costs.

Meta-analyses are becoming increasingly popular, especially in the fields of cardiovascular disease prevention and treatment. They are often considered to be a reliable source of evidence for making healthcare decisions. Unfortunately, problems among meta-analyses such as the misapplication and misinterpretation of statistical methods and tests are long-standing and widespread. The purposes of this statement are to review key steps in the development of a meta-analysis and to provide recommendations that will be useful for carrying out meta-analyses and for readers and journal editors, who must interpret the findings and gauge methodological quality. To make the statement practical and accessible, detailed descriptions of statistical methods have been omitted. Based on a survey of cardiovascular meta-analyses, published literature on methodology, expert consultation, and consensus among the writing group, key recommendations are provided. Recommendations reinforce several current practices, including protocol registration; comprehensive search strategies; methods for data extraction and abstraction; methods for identifying, measuring, and dealing with heterogeneity; and statistical methods for pooling results. Other practices should be discontinued, including the use of levels of evidence and evidence hierarchies to gauge the value and impact of different study designs (including meta-analyses) and the use of structured tools to assess the quality of studies to be included in a meta-analysis. We also recommend choosing a pooling model for conventional meta-analyses (fixed effect or random effects) on the basis of clinical and methodological similarities among studies to be included, rather than the results of a test for statistical heterogeneity.

Youth in the criminal justice system commonly suffer from multiple medical and psychological health problems. Because they likely live in lower socioeconomic environments, the medical care they receive through the justice system might be their only recent medical care and can result in the discovery of health problems or chronic illnesses that must be managed while in the system and beyond. We describe the case of an adolescent diagnosed with a serious chronic disease during his time in an urban detention center to illustrate how health workers and justice staff must use a team approach in caring for this vulnerable population of children. Barriers to appropriate care, including social and systems-level challenges, are discussed. The lessons learned in this case can be applied more broadly to other vulnerable youth populations, including those in foster care and impoverished communities where the primary care pediatrician (or other assigned pediatric specialist) is both the leader of the medical team and an advocate for quality care.

The purpose of this study was to develop a participant-informed technology-based physical activity (PA) promotion tool for young overweight and obese African American (AA) women. A mixed-method 3-phase study protocol design was used to develop text messages to promote PA in AA women attending the University of Alabama at Birmingham during the Spring of 2013. Nominal focus groups and a 2-week pilot were used to generate and test participant-developed messages. Participants ( n = 14) had a mean age of 19.79 years ( SD = 1.4) and mean body mass index of 35.9 ( SD = 5.926). Focus group data identified key themes associated with the use of text messages to promote PA including message frequency, length, tone, and time of day. Participants preferred text messages that were brief, specific, and time sensitive. Results showed that text messaging was a feasible and acceptable strategy to promote PA in overweight and obese AA women in a university setting.

OBJECTIVE: To better understand the association between a modified Mediterranean diet pattern in young adulthood, cardiorespiratory fitness in young adulthood, and the odds of developing pre-diabetes or diabetes by middle age. RESEARCH DESIGN AND METHODS: Participants from the Coronary Artery Risk Development in Young Adults (CARDIA) study who did not have pre-diabetes or diabetes at baseline (year 0 (Y0), ages 18-30) and who had data available at the Y0 and year 25 (Y25) visits were included in this analysis (n=3358). Polytomous logistic regression models were used to assess the association between baseline dietary intake and fitness data and odds of pre-diabetes or diabetes by middle age (Y25, ages 43-55). RESULTS: At the Y25 visit, 1319 participants (39%) had pre-diabetes and 393 (12%) had diabetes. Higher baseline fitness was associated with lower odds of pre-diabetes and of diabetes at Y25. After adjustment for covariates, each SD increment in treadmill duration (181â s) was associated with lower odds for pre-diabetes (OR 0.85, 95% CI 0.75 to 0.95, p=0.005) and for diabetes (OR 0.71, 95% CI 0.60 to 0.85, p=0.0002) when compared to normal glycemia. A modified Mediterranean diet pattern was not associated with either pre-diabetes or diabetes. No interaction between cardiorespiratory fitness and dietary intake was observed, but baseline fitness remained independently associated with incident pre-diabetes and diabetes following adjustment for diet. CONCLUSIONS: Higher cardiorespiratory fitness in young adulthood, but not a modified Mediterranean diet pattern, is associated with lower odds of pre-diabetes and of diabetes in middle age. TRIAL REGISTRATION NUMBER: NCT00005130.
RESUMO
OBJECTIVE: To examine 25-year trends in weight gain, partitioned by time-related and aging-related changes, during early and middle adulthood. METHODS: Coronary Artery Risk Development in Young Adults (CARDIA), a prospective, non-nationally representative cohort study conducted at four urban field centers that began in 1985 to 1986 with 5,109 Black (B) and White (W) men (M) and women (W) aged 18 to 30 years, has followed participants for 25 years (aged 43-55 years in 2010-2011). Time-related and aging-related components of weight change were estimated to construct longitudinal models of linear and nonlinear trends. RESULTS: There were nonlinear trends in time-related weight gain in W, with larger weight gains early that attenuated at subsequent exams. Time-related trends were linear in M. There were nonlinear trends in aging-related weight gain in BM, BW, and WM, with the greatest weight gains at younger ages. Aging-related trends were linear in WW. Participants with overweight or obesity in early adulthood had greater attenuation of aging-related weight gain during middle adulthood. CONCLUSIONS: These findings partially support recent surveys indicating slower increases in obesity prevalence in recent years. Findings further suggest that aging-related weight gain is greatest in the 20s and may begin attenuating as early as the mid-30s among some groups.

OBJECTIVE: Despite variability in the burden of elevated depressive symptoms by sex and race and differences in the incidence of metabolic syndrome, few prior studies describe the longitudinal association of depressive symptoms with metabolic syndrome in a diverse cohort. We tested whether baseline and time-varying depressive symptoms were associated with metabolic syndrome incidence in black and white men and women from the Coronary Artery Risk Development in Young Adults study. METHODS: Participants reported depressive symptoms using the Center for Epidemiologic Studies Depression Scale at four examinations between 1995 and 2010. At those same examinations, metabolic syndrome was determined. Cox proportional hazards models were used to examine the associations of depressive symptoms on the development of metabolic syndrome in 3208 participants without metabolic syndrome at baseline. RESULTS: For 15 years, the incidence rate of metabolic syndrome (per 10,000 person-years) varied by race and sex, with the highest rate in black women (279.2), followed by white men (241.9), black men (204.4), and white women (125.3). Depressive symptoms (per standard deviation higher) were associated with incident metabolic syndrome in white men (hazard ratio = 1.25, 95% confidence interval = 1.08-1.45) and white women (hazard ratio = 1.17, 95% confidence interval = 1.00-1.37) after adjustment for demographic characteristics and health behaviors. There was no significant association between depression and metabolic syndrome among black men or black women. CONCLUSIONS: Higher depressive symptoms contribute modestly to the onset of metabolic syndrome among white adults.

AIMS/HYPOTHESIS: The prospective association between cardiorespiratory fitness (CRF) measured in young adulthood and middle age on development of prediabetes, defined as impaired fasting glucose and/or impaired glucose tolerance, or diabetes by middle age remains unknown. We hypothesised that higher fitness levels would be associated with reduced risk for developing incident prediabetes/diabetes by middle age. METHODS: Participants were from the Coronary Artery Risk Development in Young Adults (CARDIA) study who were free from prediabetes/diabetes at baseline (year 0 [Y0]: 1985-1986). CRF was quantified by treadmill duration (converted to metabolic equivalents [METs]) at Y0, Y7 and Y20 and prediabetes/diabetes status was assessed at Y0, Y7, Y10, Y15, Y20 and Y25. We use an extended Cox model with CRF as the primary time-varying exposure. BMI was included as a time-varying covariate. The outcome was development of either prediabetes or diabetes after Y0. Model 1 included age, race, sex, field centre, CRF and BMI. Model 2 additionally included baseline (Y0) smoking, energy intake, alcohol intake, education, systolic BP, BP medication use and lipid profile. RESULTS: Higher fitness was associated with lower risk for developing incident prediabetes/diabetes (difference of 1 MET: HR 0.99898 [95% CI 0.99861, 0.99940], p < 0.01), which persisted (difference of 1 MET: HR 0.99872 [95% CI 0.99840, 0.99904], p < 0.01] when adjusting for covariates. CONCLUSIONS/INTERPRETATION: Examining participants who had fitness measured from young adulthood to middle age, we found that fitness was associated with lower risk for developing prediabetes/diabetes, even when adjusting for BMI over this time period. These findings emphasise the importance of fitness in reducing the health burden of prediabetes and diabetes.

PURPOSE: This study evaluated a culturally relevant, social cognitive theory-based, Internet-enhanced physical activity (PA) pilot intervention developed for overweight/obese African American (AA) female college students. DESIGN: Using a 3-month, single group, pretest-posttest design, participants accessed a culturally relevant PA promotion website and engaged in four moderate-intensity PA sessions each week. RESULTS: Study completers (n = 25, mean age = 21.9 years) reported a decrease in sedentary screen time (p < .0001); however, no changes in moderate-to-vigorous PA were reported (p = .150). A significant increase in self-regulation for PA (p < .0001) and marginally significant increases in social support (p = .052) and outcome expectations (p = .057) for PA were observed. No changes in body mass index (p = .162), PA enjoyment (p = .151), or exercise self-efficacy (p = .086) were reported. CONCLUSIONS: Findings of this exploratory study show some preliminary support for Internet-enhanced approaches to promote PA among overweight/obese AA women. IMPLICATIONS FOR PRACTICE: Future studies with larger samples are needed to further explore culturally relevant Internet-enhanced PA programs in this underserved population.

OBJECTIVES: Adolescent mothers have differing risks and responsibilities compared to adolescent women without children that may impact substance use treatment. This study sought to describe characteristics of adolescent women in a substance use treatment program and determine the effect of adolescent motherhood on treatment program outcomes. METHODS: Data were collected from standardized interviews of female adolescents in a case management criminal justice diversion program for substance-using adolescents and adults. Variables included sociodemographic factors (ie, race/ethnicity, age, financial support, education, insurance, marital status, sexual abuse), Diagnostic and Statistical Manual-IV (DSM-IV) substance use disorder diagnoses, and motherhood (ie, childbirth and residence with a child). Treatment program outcome was documented by case workers at the end of the participants' time in the program. Chi-square analyses and analysis of variances determined associations between variables. Logistic regression was used to assess characteristics associated with negative treatment program outcome. RESULTS: Data from 1080 adolescent women aged 16-21 years (mean 19.7 years, SDâ=â1.16) were analyzed; 403 (37%) were mothers. After controlling for sociodemographic factors and substance use disorder diagnoses, adolescent mothers were less likely to successfully complete the treatment program than nonmothers. Adolescent women with reliance on family or friends for financial support, lower education status, and cannabis and cocaine use disorders had worse treatment program outcomes. CONCLUSIONS: Childbirth and parenting adversely affect substance use treatment outcomes for adolescent women in the criminal justice system. Future research should explore tailored substance use treatments for adolescents with children. Job training and educational support may improve outcomes.

BACKGROUND: African American women are one of the least active demographic groups in the US, with only 36% meeting the national physical activity recommendations in comparison to 46% of White women. Physical activity begins to decline in African American women in adolescence and continues to decline into young adulthood. Yet, few interventions have been developed to promote physical activity in African American women during this critical period of life. The purpose of this article was to evaluate the acceptability and feasibility of a culturally-relevant Internet-enhanced physical activity pilot intervention for overweight/obese African American college females and to examine psychosocial and behavioral characteristics associated with intervention adherence and completion. METHODS: A 6-month single group pre-posttest design was used. Participants (n = 27) accessed a culturally-relevant Social Cognitive Theory-based physical activity promotion website while engaging in a minimum of four moderate-intensity physical activity sessions each week. Acceptability and feasibility of the intervention was assessed by participant retention and a consumer satisfaction survey completed by participants. RESULTS: Fifty-six percent of participants (n = 15) completed the intervention. Study completers were more physically active at baseline (P = 0.05) and had greater social support for exercise from family members (P = 0.04). Sixty percent of study completers (n = 9) reported the website as "enjoyable" or "very enjoyable" to use and 60% (n = 9) reported increased motivation from participation in the physical activity program. Moreover, 87% (n = 13) reported they would recommend the website to a friend. CONCLUSIONS: Results provide some preliminary support for the acceptability and feasibility of an Internet-enhanced physical activity program for overweight/obese African American women, while highlighting important limitations of the approach. Successful promotion of physical activity in college aged African American women as they emerge into adulthood may result in the development of life-long healthy physical activity patterns which may ultimately reduce physical activity-related health disparities in this high risk underserved population. Future studies with larger samples are needed to further explore the use of Internet-based programs to promote physical activity in this population.

BACKGROUND: Type 2 diabetes mellitus (T2D) and cardiovascular disease share risk factors and subclinical atherosclerosis (SCA) predicts events in those with and without diabetes mellitus. T2D genetic risk may predict both T2D and SCA. We hypothesized that greater T2D genetic risk is associated with higher extent of SCA. METHODS AND RESULTS: In a cross-sectional analysis, including ≤9210 European Americans, 3773 African Americans, 1446 Hispanic Americans, and 773 Chinese Americans without known cardiovascular disease and enrolled in the Framingham Heart Study, Coronary Artery Risk Development in Young Adults, Multi-Ethnic Study of Atherosclerosis, and Genetic Epidemiology Network of Arteriopathy studies, we tested a 62 T2D-loci genetic risk score for association with measures of SCA, including coronary artery or abdominal aortic calcium score, common and internal carotid artery intima-media thickness, and ankle-brachial index. We used ancestry-stratified linear regression models, with random effects accounting for family relatedness when appropriate, applying a genetic-only (adjusted for sex) and a full SCA risk factors-adjusted model (significance, P<0.01=0.05/5, number of traits analyzed). An inverse association with coronary artery calcium score in Multi-Ethnic Study of Atherosclerosis Europeans (fully-adjusted P=0.004) and with common carotid artery intima-media thickness in the Framingham Heart Study (P=0.009) was not confirmed in other study cohorts, either separately or in meta-analysis. Secondary analyses showed no consistent associations with ß-cell and insulin resistance genetic risk sub-scores in the Framingham Heart Study and in the Coronary Artery Risk Development in Young Adults. CONCLUSIONS: SCA does not have a major genetic component linked to a burden of 62 T2D loci identified by large genome-wide association studies. A shared T2D-SCA genetic basis, if any, might become apparent from better functional information about both T2D and cardiovascular disease risk loci.

Obesity is a topic on which many views are strongly held in the absence of scientific evidence to support those views, and some views are strongly held despite evidence to contradict those views. We refer to the former as "presumptions" and the latter as "myths." Here, we present nine myths and 10 presumptions surrounding the effects of rapid weight loss; setting realistic goals in weight loss therapy; stage of change or readiness to lose weight; physical education classes; breastfeeding; daily self-weighing; genetic contribution to obesity; the "Freshman 15"; food deserts; regularly eating (versus skipping) breakfast; eating close to bedtime; eating more fruits and vegetables; weight cycling (i.e., yo-yo dieting); snacking; built environment; reducing screen time in childhood obesity; portion size; participation in family mealtime; and drinking water as a means of weight loss. For each of these, we describe the belief and present evidence that the belief is widely held or stated, reasons to support the conjecture that the belief might be true, evidence to directly support or refute the belief, and findings from randomized controlled trials, if available. We conclude with a discussion of the implications of these determinations, conjecture on why so many myths and presumptions exist, and suggestions for limiting the spread of these and other unsubstantiated beliefs about the obesity domain.

This article provides a comprehensive review of Internet- and Website-based physical activity interventions targeting adult populations. Search procedures identified 72 unique Internet-based physical activity interventions published in peer-reviewed journals. Participants of the studies were predominately White, middle-aged (mean age = 43.3 years), and female (65.9%). Intervention durations ranged from 2 weeks to 13 months (median = 12 weeks). Forty-six of the studies were randomized controlled trials, 21 were randomized trials without a control condition, 2 were non-randomized controlled trials, and 3 used a single-group design. The majority of studies (n = 68) assessed outcomes immediately following the end of the intervention period, and 16 studies provided delayed postintervention assessments. Forty-four of the 72 studies (61.1%) reported significant increases in physical activity. Future directions for Internet-based physical activity interventions include increasing representation of minority and male populations in Internet-based efforts, conducting delayed postintervention follow-up assessments, and incorporating emerging technologies (ie, cellular and Smartphones) into Internet-based physical activity efforts.
RESUMO
INTRODUCTION: Innovative approaches are needed to promote physical activity among young adult overweight and obese African American women. We sought to describe key elements that African American women desire in a culturally relevant Internet-based tool to promote physical activity among overweight and obese young adult African American women. METHODS: A mixed-method approach combining nominal group technique and traditional focus groups was used to elicit recommendations for the development of an Internet-based physical activity promotion tool. Participants, ages 19 to 30 years, were enrolled in a major university. Nominal group technique sessions were conducted to identify themes viewed as key features for inclusion in a culturally relevant Internet-based tool. Confirmatory focus groups were conducted to verify and elicit more in-depth information on the themes. RESULTS: Twenty-nine women participated in nominal group (n = 13) and traditional focus group sessions (n = 16). Features that emerged to be included in a culturally relevant Internet-based physical activity promotion tool were personalized website pages, diverse body images on websites and in videos, motivational stories about physical activity and women similar to themselves in size and body shape, tips on hair care maintenance during physical activity, and online social support through social media (eg, Facebook, Twitter). CONCLUSION: Incorporating existing social media tools and motivational stories from young adult African American women in Internet-based tools may increase the feasibility, acceptability, and success of Internet-based physical activity programs in this high-risk, understudied population.

OBJECTIVE: To examine self-reported weight discrimination and differences based on race, sex, and BMI in a biracial cohort of community-based middle-aged adults. DESIGN AND METHODS: Participants (3,466, mean age = 50 years, mean BMI = 30 kg/m²) of the Coronary Artery Risk Development in Young Adults (CARDIA) Study who completed the 25-year examination of this epidemiological investigation in 2010-2011 were reported. The sample included normal weight, overweight, and obese participants. CARDIA participants are distributed into four race-sex groups, with about half being African-American and half White. Participants completed a self-reported measure of weight discrimination. RESULTS: Among overweight/obese participants, weight discrimination was lowest for White men (12.0%) and highest for White women (30.2%). The adjusted odds ratio (95% CI) for weight discrimination in those with class 2/3 obesity (BMI ≥ 35 kg/m²) versus the normal-weight was most pronounced: African American men, 4.59 (1.71-12.34); African American women, 7.82 (3.57-17.13); White men, 6.99 (2.27-21.49); and White women, 18.60 (8.97-38.54). Being overweight (BMI = 25-29.9 kg/m²) vs. normal weight was associated with increased discrimination in White women only: 2.10 (1.11-3.96). CONCLUSIONS: Novel evidence for a race-sex interaction on perceived weight discrimination, with White women more likely to report discrimination at all levels of overweight and obesity was provided. Pychosocial mechanisms responsible for these differences deserve exploration.

BACKGROUND: The Internet presents a widely accessible, 24-h means to promote chronic disease management. The objective of this review is to identify studies that used Internet based interventions to promote lifestyle modification among adults with type 2 diabetes. METHODS: We searched PubMed using the terms: [internet, computer, phone, smartphone, mhealth, mobile health, web based, telehealth, social media, text messages] combined with [diabetes management and diabetes control] through January 2013. Studies were included if they described an Internet intervention, targeted adults with type 2 diabetes, focused on lifestyle modification, and included an evaluation component with behavioral outcomes. RESULTS: Of the 2803 papers identified, nine met inclusion criteria. Two studies demonstrated improvements in diet and/or physical activity and two studies demonstrated improvements in glycemic control comparing web-based intervention with control. Successful studies were theory-based, included interactive components with tracking and personalized feedback, and provided opportunities for peer support. Website utilization declined over time in all studies that reported on it. Few studies focused on high risk, underserved populations. CONCLUSION: Web-based strategies provide a viable option for facilitating diabetes self-management. Future research is needed on the use of web-based interventions in underserved communities and studies examining website utilization patterns and engagement over time.

This research team has designed and implemented 2 culturally relevant, Internet-enhanced physical activity (PA) interventions for overweight/obese African-American female college students. Presumably, these are the only prospectively designed, culturally relevant interventions using the Internet to promote PA among African-American women. Due to the limited research on this topic, the experiences associated the design and implementation of these studies were syntesized and 5 key lessons learned from this research were formulated. Findings provide insight for researchers to consider when developing Internet-based PA promotion interventions for African-American women. Lessons learned included: 1) Elicit and incorporate feedback from the target population throughout development of an Internet-based PA promotion tool; 2) Incorporate new and emerging technologies into Internet-enhanced PA programs; 3) Maintain frequent participant contact and provide frequent incentives to promote participant engagement; 4) Supplement Internet-based efforts with face-to-face interactions; 5) Include diverse images of African-American women and culturally relevant PA-related information in Internet-based PA promotion materials.
RESUMO
BACKGROUND: Many beliefs about obesity persist in the absence of supporting scientific evidence (presumptions); some persist despite contradicting evidence (myths). The promulgation of unsupported beliefs may yield poorly informed policy decisions, inaccurate clinical and public health recommendations, and an unproductive allocation of research resources and may divert attention away from useful, evidence-based information. METHODS: Using Internet searches of popular media and scientific literature, we identified, reviewed, and classified obesity-related myths and presumptions. We also examined facts that are well supported by evidence, with an emphasis on those that have practical implications for public health, policy, or clinical recommendations. RESULTS: We identified seven obesity-related myths concerning the effects of small sustained increases in energy intake or expenditure, establishment of realistic goals for weight loss, rapid weight loss, weight-loss readiness, physical-education classes, breast-feeding, and energy expended during sexual activity. We also identified six presumptions about the purported effects of regularly eating breakfast, early childhood experiences, eating fruits and vegetables, weight cycling, snacking, and the built (i.e., human-made) environment. Finally, we identified nine evidence-supported facts that are relevant for the formulation of sound public health, policy, or clinical recommendations. CONCLUSIONS: False and scientifically unsupported beliefs about obesity are pervasive in both scientific literature and the popular press. (Funded by the National Institutes of Health.).
