RESUMO
BACKGROUND: Postpartum weight retention contributes to weight gain and obesity. Remotely delivered lifestyle interventions may be able to overcome barriers to attending in-person programs during this life phase. OBJECTIVE: This study aimed to conduct a randomized feasibility pilot trial of a 6-month postpartum weight loss intervention delivered via Facebook or in-person groups. Feasibility outcomes were recruitment, sustained participation, contamination, retention, and feasibility of study procedures. Percent weight loss at 6 and 12 months were exploratory outcomes. METHODS: Women with overweight or obesity who were 8 weeks to 12 months post partum were randomized to receive a 6-month behavioral weight loss intervention based on the Diabetes Prevention Program lifestyle intervention via Facebook or in-person groups. Participants completed assessments at baseline, 6 months, and 12 months. Sustained participation was defined by intervention meeting attendance or visible engagement in the Facebook group. We calculated percent weight change for participants who provided weight at each follow-up. RESULTS: Among individuals not interested in the study, 68.6% (72/105) were not interested in or could not attend in-person meetings and 2.9% (3/105) were not interested in the Facebook condition. Among individuals excluded at screening, 18.5% (36/195) were ineligible owing to reasons related to the in-person condition, 12.3% (24/195) related to the Facebook condition, and 2.6% (5/195) were unwilling to be randomized. Randomized participants (n=62) were a median of 6.1 (IQR 3.1-8.3) months post partum, with a median BMI of 31.7 (IQR 28.2-37.4) kg/m2. Retention was 92% (57/62) at 6 months and 94% (58/62) at 12 months. The majority (21/30, 70%) of Facebook and 31% (10/32) of in-person participants participated in the last intervention module. Half (13/26, 50%) of Facebook and 58% (15/26) of in-person participants would be likely or very likely to participate again if they had another baby, and 54% (14/26) and 70% (19/27), respectively, would be likely or very likely to recommend the program to a friend. In total, 96% (25/26) of Facebook participants reported that it was convenient or very convenient to log into the Facebook group daily compared with 7% (2/27) of in-person participants who said it was convenient or very convenient to attend group meetings each week. Average weight loss was 3.0% (SD 7.2%) in the Facebook condition and 5.4% (SD 6.8%) in the in-person condition at 6 months, and 2.8% (SD 7.4%) in the Facebook condition and 4.8% (SD 7.6%) in the in-person condition at 12 months. CONCLUSIONS: Barriers to attending in-person meetings hampered recruitment efforts and intervention participation. Although women found the Facebook group convenient and stayed engaged in the group, weight loss appeared lower. Research is needed to further develop care models for postpartum weight loss that balance accessibility with efficacy.

Research shows that a diverse faculty improves academic, clinical, and research outcomes in higher education. Despite that, persons in minority groups, usually categorized by race or ethnicity, are underrepresented in academia (URiA). The Nutrition Obesity Research Centers (NORCs), supported by the NIDDK, hosted workshops on five separate days in September and October 2020. NORCs convened these workshops to identify barriers and facilitators for diversity, equity, and inclusion (DEI) and provide specific recommendations to improve DEI within obesity and nutrition for individuals from URiA groups. Recognized experts on DEI presented each day, after which the NORCs conducted breakout sessions with key stakeholders who engage in nutrition and obesity research. The breakout session groups included early-career investigators, professional societies, and academic leadership. The consensus from the breakout sessions was that glaring inequities affect URiA in nutrition and obesity, particularly related to recruitment, retention, and advancement. Recommendations from the breakout sessions to improve DEI across the academe focused on six themes: (1) recruitment, (2) retention, (3) advancement, (4) intersectionality of multiple challenges (e.g., being Black and a woman), (5) funding agencies, and (6) implementation of strategies to address problems related to DEI.

Many parents and pregnant women in the US use social media to access health-related information. Estimates of current use of different platforms among these populations are needed. We used data from a 2021 Pew Research Center survey to describe use of commercial social media platforms by US parents and US women aged 18 to 39 years. Most US parents and women of childbearing age use YouTube, Facebook, and Instagram, with most engaging daily. Understanding social media use patterns can help public health professionals, health care systems, and researchers reach selected populations with evidence-based health information and health promotion programs.

Objective: Black Feminism and Womanism offers an interdisciplinary lens and practice to center Black women's health, engage relevant health, and create Black women-informed solutions to address obesity. The purpose of this review article is to employ Black Feminism and Womanism to examine approaches and results of Black women-centered behavioral weight loss interventions. Methods: A narrative review of Black women-centered behavioral weight loss interventions was conducted. To be included, articles met the following criteria: published between 2012 and 2022, standard behavioral treatment for weight loss, randomized design, weight loss outcomes stratified by race and gender, sample size of at least 75 individuals, adults at least 18 years of age, and at least 51% Black women in the sample. Results: Eight studies met the inclusion criteria for a Black women-centered behavioral weight loss intervention and were evaluated. Findings indicate that weight loss among Black women was mostly low, below the clinical target of 5 to 10% weight loss. Intervention designs ranged widely in their approach to respond to the context of Black women's lives, with little consistency between designs. Conclusions: To make meaningful improvement in the effectiveness of behavioral weight loss interventions for Black women, new approaches are critical. Approaches grounded in Black Feminism and Womanism can provide the essential foundation to generate new knowledge, novel hypotheses, and intervention designs that fully attend to the lived context of Black women, including consideration of the potential health effects of gendered racism.

PURPOSE: To examine the relationship between the multiple caregiver role and its perceived barriers to self-care on behavioral adherence in a weight loss intervention. DESIGN: A secondary analysis of data from a behavioral weight loss intervention. SETTING: The study was conducted in two cohorts from March 2016 to February 2017 at the University of North Carolina at Chapel Hill. SUBJECTS: Eighty-one Black women with overweight/obesity (age = 48.4 ± 10.9 years [M ± SD], BMI = 36.4 ± 4.5 kg/m2 [M ± SD]). MEASURES: Identification with the multiple caregiver role and barriers was assessed with the Multiple Caregiving Measurement Instrument. Weight was measured with a digital scale and height with a stadiometer. The Block food frequency questionnaire evaluated dietary intake. Moderate-to-vigorous physical activity (MVPA) was measured objectively with an accelerometer. Study adherence was measured by session attendance, self-weighing, and self-monitoring (diet and physical activity) frequency. ANALYSIS: Generalized linear models were used to examine the relationship between the multiple caregiver scales and the outcomes of interest, controlling for study arm, cohort, and income. Chi-square tests tested correlations. RESULTS: Greater identification with the multiple caregiver role was associated with decreased session attendance (ß = -.56 [SE = .27], P < .05) and a trend towards weight gain (ß = .36, [SE = .19], P = .07). Greater multiple caregiver barriers score predicted a decrease in fruit/vegetable intake (ß = -.17 [SE = .07], P < .05). All regression results are unstandardized. Negative correlations between multiple caregiver barriers and MVPA (r = -.24, P = .06) and daily self-weighing (r = -.19, P = .10) approached significance. CONCLUSIONS: Participants' identification with multiple caregiving role and barriers can reduce adherence, behavior and weight change. Interventions to address Black women's multiple roles and barriers during weight loss are needed to maximize outcomes.

There is limited research on whether run-in procedures predict participant adherence during behavioral efficacy trials. This study examined whether information from behavioral run-ins (food diary completion, questionnaire completion, and staff interview) predict intervention adherence, trial retention, and trial outcomes in a behavioral weight loss trial. Using run-in data, trial staff predicted which participants would have high, moderate, or low trial adherence. Participants with predicted high or moderate adherence were randomized. Results showed that predicted high adherers had better intervention adherence (session attendance and completion of self-monitoring records) and superior trial outcomes (i.e. weight loss). Run-in data did not predict trial retention. Results suggest that run-ins may be effective at identifying participants adherent to intervention protocols, thereby enhancing internal validity of behavioral efficacy trials.

Religion and spirituality (R/S) play a central role in shaping the contextual experiences of many Black people in the United States. Blacks are among the most religiously engaged groups in the country. Levels and types of religious engagement, however, can vary by subcategories such as gender or denominational affiliation. Although R/S involvement has been linked to improved mental health outcomes for Black people in general, it is unclear whether these benefits extend to all Black people who claim R/S affiliation irrespective of denomination and gender. Data from the National Survey of American Life (NSAL) sought to determine whether there are differences in the odds of reporting elevated depressive symptomology among African American and Black Caribbean Christian adults across denominational affiliation and gender. Initial logistic regression analysis found similar odds of elevated depressive symptoms across gender and denominational affiliation, but further analysis revealed the presence of a denomination by gender interaction. Specifically, there was a significantly larger gender gap in the odds of reporting elevated depression symptoms for Methodists than for Baptists and Catholics. In addition, Presbyterian women had lower odds of reporting elevated symptoms than Methodist women. This study's findings highlight the importance of examining denominational disparities among Black Christians, and suggest that denomination and gender may work in tandem to shape the R/S experiences and mental health outcomes of Black people in the United States.
RESUMO
OBJECTIVE: Disparities in obesity highlight the need for an examination of determinants that may be uniquely experienced by race and sex. An understudied factor is household composition with the potential for variation in its obesogenic impacts. This study examines the association between household composition and body mass index (BMI) among Black, Hispanic, and White adults and determines whether income moderates these associations. METHODS: Using cross-sectional data from the 2011-2018 National Health and Nutrition Examination Survey, the number of children and adults aged ≥ 60 years in the household were reported among non-Hispanic Black and White adults as well as Hispanic adults aged 20-59 years old. Multivariable linear regressions were used to assess the associations between household composition and BMI with income as a potential moderator. RESULTS: Having multiple school-aged children was associated with higher BMI (ß = 1.34, standard error (s.e.) = 0.50) among Hispanic men, while having older adults in the household was associated with lower BMI among Black women (ß = - 3.21, s.e. = 1.42). Income moderated the associations between household composition and BMI among Black women and men. There were no associations between household composition and BMI in White women or men. CONCLUSIONS: Future studies should further explicate the mechanisms of household composition that uniquely impact obesity outcomes among Black women and men by income. Efforts to address higher BMI among those with more young children in the household should target Hispanic men.

The COVID-19 crisis and parallel Black Lives Matter movement have amplified longstanding systemic injustices among people of color (POC). POC have been differentially affected by COVID-19, reflecting the disproportionate burden of ongoing chronic health challenges associated with socioeconomic inequalities and unhealthy behaviors, including a lack of physical activity. Clear and well-established benefits link daily physical activity to health and well-being-physical, mental, and existential. Despite these benefits, POC face additional barriers to participation. Thus, increasing physical activity among POC requires additional considerations so that POC can receive the same opportunities to safely participate in physical activity as Americans who are White. Framed within the Ecologic Model of Physical Activity, this commentary briefly describes health disparities in COVID-19, physical activity, and chronic disease experienced by POC; outlines underlying putative mechanisms that connect these disparities; and offers potential solutions to reduce these disparities. As behavioral medicine leaders, we advocate that solutions must redirect the focus of behavioral research toward community-informed and systems solutions.

BACKGROUND: With the increasing use of mobile devices to access the internet and as the main computing system of apps, there is a growing market for mobile health apps to provide self-care advice. Their effectiveness with regard to diet and fitness tracking, for example, needs to be examined. The majority of American adults fail to meet daily recommendations for healthy behavior. Testing user engagement with an app in a controlled environment can provide insight into what is effective and not effective in an app focused on improving diet and exercise. OBJECTIVE: We developed Rams Have Heart, a mobile app, to support a cardiovascular disease (CVD) intervention course. The app tracks healthy behaviors, including fruit and vegetable consumption and physical activity, throughout the day. This paper aimed to present its functionality and evaluated adherence among the African American college student population. METHODS: We developed the app using the Personal Health Informatics and Intervention Toolkit, a software framework. Rams Have Heart integrates self-reported health screening with health education, diary tracking, and user feedback modules to acquire data and assess progress. The parent study, conducted at a historically black college and university-designated institution in southeastern United States, consisted of a semester-long intervention administered as an academic course in the fall, for 3 consecutive years. Changes were made after the cohort 1 pilot study, so results only include cohorts 2 and 3, comprising a total of 115 students (n=55 intervention participants and n=54 control participants) aged from 17 to 24 years. Data collected over the study period were transferred using the secure Hypertext Transfer Protocol Secure protocol and stored in a secure Structured Query Language server database accessible only to authorized persons. SAS software was used to analyze the overall app usage and the specific results collected. RESULTS: Of the 55 students in the intervention group, 27 (49%) students in cohort 2 and 25 (45%) in cohort 3 used the Rams Have Heart app at least once. Over the course of the fall semester, app participation dropped off gradually until exam week when most students no longer participated. The average fruit and vegetable intake increased slightly, and activity levels decreased over the study period. CONCLUSIONS: Rams Have Heart was developed to allow daily tracking of fruit and vegetable intake and physical activity to support a CVD risk intervention for a student demographic susceptible to obesity, heart disease, and type 2 diabetes. We conducted an analysis of app usage, function, and user results. Although a mobile app provides privacy and flexibility for user participation in a research study, Rams Have Heart did not improve compliance or user outcomes. Health-oriented research studies relying on apps in support of user goals need further evaluation.

OBJECTIVES: Weight control is an exercise benefit, important for older Black women, a group experiencing obesity disparities. We compared perceived exercise benefits and barriers between Black women with and without obesity and determined which mediated the weight group-exercise relationship. METHODS: A survey (n = 234) was administered to determine attitudinal agreement between weight groups (obese or non-obese). Multiple mediation analysis was used to investigate if attitudes mediated the weight group-exercise relationship. RESULTS: High agreement with all exercise benefits was observed between women with and without obesity. Compared with women without obesity, women with obesity were more likely to report the barriers of only exercising to lose weight (OR = 2.52, 95% CI 1.40-4.55), lack of will power (OR = 1.82, 95% CI 1.05-3.19), weight (OR = 3.04, 95% CI 1.34-6.83), and cost (OR = 2.14, 95% CI 1.02-4.47). Exercising to lose weight and lack of will power mediated the weight group-exercise relationship. CONCLUSIONS: Women largely agreed on the exercise benefits. Lack of will power and engaging in exercise only for weight loss were barriers that were more common among older Black women with obesity. The barriers partially explained the lower exercise engagement in women with obesity. Future work may address these barriers to increase exercise in older Black women.

OBJECTIVE: Racial differences in BMI increase with education. Weight perception may be an important factor in overweight and obesity in black women. The aim of this study was to determine the mediating role of weight underassessment on race differences in BMI in college graduates compared with non-college graduates. METHODS: Weight perception was assessed among respondents to the 2007-2014 National Health and Nutrition Examination Survey (n = 4,871). Those who had BMI-assessed overweight or obesity and self-assessed underweight or about-right weight underassessed their weight. The associations between race and BMI through weight underassessment by college graduate status were determined using a moderated mediation analysis. RESULTS: Black women had higher BMI than white women (ß = 2.72, SE = 0.28), and disparities were larger in college graduates (ß = 3.50, SE = 0.25) compared with non-college graduates (ß = 0.78, SE = 0.15). Non-college graduate black women were more likely to underassess their weight (z score = 0.43, SE = 0.05). Indirect associations between race and BMI through weight underassessment were found only among non-college graduates (z score = -0.02, SE = 0.01), but race differences in BMI remained after accounting for weight perception among college graduates and non-college graduates. CONCLUSIONS: This study demonstrates that a nuanced, intersectional understanding of weight perception and BMI among women is required to address racial disparities in obesity.

Black women typically lose small amounts of weight in behavioral weight loss interventions, partially due to low engagement in physical activity. Culturally relevant enhancement of the physical activity component may improve weight loss. This study compared the effectiveness of a culturally-relevant, physical activity-enhanced behavioral weight loss intervention to a standard behavioral weight loss intervention in Black women (n = 85) over 6 months. The study was conducted in two cohorts from March 2016 to February 2017 at the University of North Carolina at Chapel Hill. Participants had an average age of 48.30 ± 11.02 years with an average body mass index of 36.46 ± 4.50 kg/m2. Standard and enhanced groups' weight change (-2.83 kg and -2.08 kg, respectively) and change in physical activity (43.93 min/ week and 15.29 min/week, respectively) did not differ between groups. Significantly more standard group participants lost 5% of baseline weight compared to enhanced group participants. This study produced typical weight loss results in Black women. Behavioral weight loss treatment remains moderately effective for Black women. Strategies to increase attendance and self-monitoring, and the inclusion of cultural contexts to weight-related behaviors are needed to improve outcomes.

Prior investigations of the relationships between religious denomination and diabetes and obesity do not consider the nuance within black faith traditions. This study used data from the National Survey of American Life (n = 4344) to identify denominational and religious attendance differences in obesity and diabetes among black Christian men and women. Key findings indicated that black Catholics and Presbyterians had lower odds of diabetes than Baptists. Black men that attended church almost daily were nearly twice as likely to be obese than those that never attend services. These results indicate that denomination and gender should inform faith-based and placed health promotion approaches.

Objective: We set out to determine if a primarily Internet-delivered behavioral weight loss intervention produced differential weight loss in African American and non-Hispanic White women, and to identify possible mediators. Design: Data for this analysis were from a randomized controlled trial, collected at baseline and 4-months. Setting: The intervention included monthly face-to-face group sessions and an Internet component that participants were recommended to use at least once weekly. Participants: We included overweight or obese African American and non-Hispanic White women (n=170), with at least weekly Internet access, who were able to attend group sessions. Intervention: Monthly face-to-face group sessions were delivered in large or small groups. The Internet component included automated tailored feedback, self-monitoring tools, written lessons, video resources, problem solving, exercise action planning tools, and social support through message boards. Main Outcome Measure: Multiple linear regression was used to evaluate race group differences in weight change. Results: Non-Hispanic White women lost more weight than African American women (-5.03% vs.-2.39%, P=.0002). Greater website log-ins and higher change in Eating Behavior Inventory score in non-Hispanic White women partially mediated the race-weight loss relationship. Conclusions: The weight loss disparity may be addressed through improved website engagement and adoption of weight control behaviors.
