Factors related to obesity and overweight among Black adolescent girls in the United States

Physical Activity and Sedentary Behaviors Trends Among Black High School Students, 2009-2019

Purpose: Physical inactivity and sedentary behaviors are key contributors to the rising rates of childhood obesity. Though many adolescents are aware of the benefits of exercise, youth in America are not sufficiently active. This study examined changes in physical activity (PA), physical education (PE), and sedentary behaviors among Black adolescents. Methods: Pooled data from Black high school students (n = 2,233) who completed the Youth Risk Behavior Survey (YRBS) from 2009-2019 in Broward County, Florida, were analyzed. Logistic and linear regression models examined trends in selected physical activity indicators. Results: There were no significant changes in recommended physical activity levels (p = .829), daily physical activity (p = .44), PE class attendance (p = .054), or the average number of days of PA engagement (p = .304) for this time period. However, there was a significant decline in daily PE class attendance, the average number of days of PE attendance, and excessive television watching (p < .001). There were also increases in excessive video gaming and computer usage (p = .002). Conclusion: Adolescents' physical activity behaviors have not declined substantially over the past decade. However, sedentary behaviors, such as computer use and video gaming, have markedly increased. Results presented here should assist in broadening the understanding of Black adolescents' views on weight and physical activity and developing local programs and interventions to promote regular physical activity aimed at this population.

Postpartum Obesity Is Associated With Increases in Child Adiposity in Midchildhood in a Cohort of Black and Dominican Youth

Background

Obesity disproportionately affects marginalized and low-income populations. Birth parent obesity from the prenatal period and childhood has been associated with child obesity. It is unknown whether prenatal or postnatal birth parent obesity has differential effects on subsequent changes in adiposity and metabolic health in children.

Objectives

We evaluated how birth parent obesity 7 y after delivery was associated with child body composition changes and cardiometabolic health in midchildhood and further assessed the influence of the perinatal and postpartum period on associations.

Methods

Black and Dominican pregnant individuals were enrolled, and dyads (n = 319) were followed up at child age 7 and 9 y. Measures included, height, weight, waist circumference (WC), and percent body fat (BF%). Multiple linear regression was used to relate postpartum weight status with child outcomes accounting for attrition, and a series of secondary analyses were conducted with additional adjustment for perinatal weight status, gestational weight gain (GWG), and/or long-term weight retention to evaluate how these factors influenced associations.

Results

Almost one-quarter (23%) of birth parents and 24.1% children were classified with obesity at child age 7 y, while at 9 y, 30% of children had obesity. Birth parent obesity at child age 7 y was associated with greater changes, from ages 7 to 9 y, in child BMI z-score (β: 0.13; 95% CI: 0.02, 0.24) and BF% (β: 1.15; 95% CI: 0.22, 2.09) but not obesity at age 9 y. All observed associations crossed the null after additional adjustment for prenatal factors.

Conclusions

Birth parent obesity at 7-y postpartum is associated with greater gains in child BMI z-score and BF% in midchildhood. These associations diminish after accounting for prenatal size, suggesting a lasting impact of the perinatal environment and that interventions supporting families from the prenatal period through childhood are needed.

Using Black Feminist Theory and Methods to Uncover Best Practices in Health Promotion Programming

This study was created to uncover the social determinants of Black American women's success in health promotion programs. We used the Superwoman Schema to understand the complexities of Black womanhood and uncover best practices in the promotion of their health. The sample consisted of women ages 18-25 who attend a large southern HBCU. We collected data using qualitative focus groups. Participants reported the greatest health-related concerns Black American women facing are mental health, obesity, and relationships with Black men. When it comes to health promotion programs, respondents reported a desire for classes that are fun, interactive, informative, educational, and include group interaction, accessible, and incentivize participation. Uncovering the social determinants of Black American women's health and program success is central in decreasing extant health disparities. Future health scholars are urged to incorporate Black feminist theory and methods into their work to create health promotion interventions tailored for Black women.

Views of Black women patients with obesity on desired and undesired weight-focused clinical encounters

Non-Hispanic Black women have the highest rates of overweight/obesity of any group in the United States. To date, few interventions have worked to reduce overweight/obesity in this population. This study investigated the views of Black women with overweight and obesity treated in a primary care setting regarding desired and undesired verbal and non-verbal behaviours by providers in provider-patient clinical encounters focused on losing weight, maintaining weight loss, and/or obesity. Two focus groups and an individual interview (n = 15) were conducted. Qualitative data analysis yielded five distinct themes, with 11 codes (listed in parenthesis): (a) desired weight-focused discussions (codes: Discussing weight loss with patients and discussing weight-loss maintenance with patients), (b) desired weight-focused support (codes: Supporting patients experiencing weight loss and supporting patients experiencing weight gain), (c) undesired weight-focused discussions (codes: Things to avoid during weight loss discussions and things to avoid during weight gain discussions), (d) desired attitudes and behaviours during weight-focused discussions (codes: Show caring and understanding and encourage behaviour change for weight loss), and (e) building physician-patient rapport (codes: Enable patients to feel respected by doctors, enable patients to feel comfortable with doctors and enable patients to trust their doctors). The qualitative approach employed in this study generates a deep understanding not only of the experiences of Black women patients but also of potential strategies that physicians could employ to succeed in their discussions with patients regarding healthy weight achievement and maintenance.

"Mane"taining: How Black Adolescent Girls Maintain Their Cultural Hair Practices in Physical Education Class

BACKGROUND

Although hair has been found to be a barrier to physical activity (PA) among adult black women, the research exploring this phenomenon among black adolescent girls is deficient. This presents a concern because physical inactivity can lead to obesity and a host of comorbidities. This qualitative study explores hair experiences of black adolescent girls and how they maintain their cultural hair practices in hopes of promoting PA among this at-risk population.

METHODS

Focus groups were conducted for 37 black adolescent girls attending a public high school in Newark, New Jersey.

RESULTS

The participants reported increasing hair knowledge via social media, sociocultural influences of family and culture, and the driving force of their peer group, a concept identified in the focus groups as Hair IQ (intelligence quotient). Hair IQ helped the participants learn how to maintain their hair practices before and after PA. These factors combined to develop a framework described as the "Mane"taining model.

CONCLUSIONS

The findings suggest the "Mane"taining model may provide pathways for engaging in PA for this population and serve as an example for adult black women who face similar barriers to PA.

Development and Feasibility of an Obesity Prevention Intervention for Black Adolescent Daughters and Their Mothers

Black female adolescents and women have disproportionately higher rates of obesity than their racial/ethnic counterparts. There is an urgent need to address obesity prevention in Black adolescent females through interventions that enhance lifestyle physical activity and improve dietary behaviors. Middle adolescence presents an important opportunity to strengthen the daughter-mother bond and improve healthy behaviors such as physical activity and dietary intake. Because of the intersection of adolescent development, culture and structural racism, it is essential to include mothers; however, this approach is understudied in the literature. This pre-pilot proof of concept study, Black Girls Move, was conducted using a 12-week pre-post within-subjects design to assess feasibility of conducting and delivering the BGM intervention, program satisfaction, and ability to obtain outcome measures in Black ninth and tenth grade daughters and their mothers. Twenty-two dyads were recruited and 14 dyads completed baseline assessments; however, only eight daughters and their mothers attended the first session and remained for the entire study. All dyads had valid objective and self-reported physical activity data. However, two of eight daughters and one mother provided self-reported dietary data that were considered invalid. All individual sessions were rated highly. Excellent attendance, retention, and satisfaction among participants suggest that we succeeded in developing an accepted, culturally relevant intervention. This lifestyle intervention would be strengthened by modifications to recruitment and retention, as well as incorporation of a computerized dietary assessment tool, a tailored dietary app for self-monitoring, and increased photo-based and group homework activities.

Systemic F2-Isoprostane Levels in Predisposition to Obesity and Type 2 Diabetes: Emphasis on Racial Differences

This review focuses on racial differences in systemic levels of lipid peroxidation markers F₂-isoprostanes as metabolic characteristics predisposing to obesity and type 2 diabetes. Elevated levels F₂-isoprostanes were found in obesity, type 2 diabetes and their comorbidities. It was hypothesized that increased F₂-isoprostane levels reflect the obesity-induced oxidative stress that promotes the development of type 2 diabetes. However, African Americans have lower levels of systemic F₂-isoprostane levels despite their predisposition to obesity and type 2 diabetes. The review summarizes new findings from epidemiological studies and a novel interpretation of metabolic determinants of systemic F₂-isoprostane levels as a favorable phenotype. Multiple observations indicate that systemic F₂-isoprostane levels reflect intensity of oxidative metabolism, a major endogenous source of reactive oxygen species, and specifically, the intensity of fat utilization. Evidence from multiple human studies proposes that targeting fat metabolism can be a productive race-specific strategy to address the existing racial health disparities. Urinary F₂-isoprostanes may provide the basis for targeted interventions to prevent obesity and type 2 diabetes among populations of African descent.
