Overcoming Inequities in Obesity: What Don't We Know That We Need to Know?

Pre-pregnancy Weight and Racial-Ethnic Disparities in Pregnancy-Associated Conditions in the State of Georgia: A Population-Based Study

INTRODUCTION

We investigate racial-ethnic disparities in pre-pregnancy obesity and pregnancy weight gain, which are known to increase the risk of pregnancy-associated conditions.

METHODS

We used 4-year (2017-2020) combined Georgia Pregnancy Risk Assessment Monitoring System data (N = 3208) to investigate racial-ethnic disparities in the incidence of gestational hypertension (GHT), gestational diabetes mellitus (GDM), and postpartum depression (PPD) and their associated risk with pre-pregnancy overweight/obesity after controlling for demographic and other confounders using regression modeling. The geographic distributions of hypertension and PPD rates at the county level were compared to the patterns of racial-ethnic populations and hospitals.

RESULTS

The PPD rates were higher among Asian (17.6), Hispanic (14.4), and Black (14.3); GDM was highest among Asian (16.0) mothers; and GHT was the highest among Black (11.7) followed by White mothers (9.0). Pre-pregnancy overweight and obese conditions increased the odds of hypertension in Black (2 ½ times) and White (> 3 ½ times) mothers. Premature birth increased the odds of hypertension (2-3 times) in all mothers. Pre-pregnancy weight also increased the odds of GDM (3-7 times) in these racial groups. Premature birth increases the odds twice as likely for PPD in Hispanic and White mothers. The convergence of high PPD and hypertension rates with high proportions of racial and ethnic minorities, and lack of hospital presence, indicates areas where healthcare interventions are required.

CONCLUSIONS

These findings underscore the importance of promoting a healthy pre-pregnancy weight to reduce the burden of maternal morbidity and pregnancy outcomes in general. More comprehensive prenatal monitoring using technological interventions for self-care has a great promise of being effective in maintaining a healthy pregnancy.

Obese patients' dissatisfaction with weight, body image and clinicians' interaction at a district hospital; Gauteng

BACKGROUND

Obesity in South Africa has created a public health crisis that warrants a multilevel intervention. However, patients' perceptions and clinicians' challenges hinder the management of obesity in primary care.

AIM

The study aimed to assess obese patients' dissatisfaction with weight and body image and their perspectives on interaction with clinicians regarding obesity management in a primary care setting.

SETTING

Outpatient department of Dr Yusuf Dadoo District Hospital.

METHODS

Cross-sectional study of 213 adult obese patients. A semi-structured questionnaire, a body image assessment tool and patients' medical records were used for data collection.

RESULTS

The study found that, contrary to popular belief, obese patients were dissatisfied with their weight (78.9%) and body image (95.3%). Many felt comfortable while discussing weight reduction with clinicians, although 37.1% reported never engaging with a doctor and 62.9% never interacted with a nurse on the subject. Only 6% reported receiving adequate information on weight reduction measures and 19.7% were followed-up. Clinicians' advice was mainly associated with patients' high body mass index and waist circumference. Doctors were less likely to recommend weight reduction to employed obese women, while nurses were more likely to engage Zulu-speaking patients. Patients were more likely to be followed up if they were young and excessively obese.

CONCLUSION

The study found that most obese patients were dissatisfied with their weight and body image and perceived their interaction with clinicians regarding obesity management as inadequate.Contribution: The study provides an angle of view of challenges in obesity management from patients' perspectives.

Estimating County Level Health Indicators Using Spatial Microsimulation

Given the importance of understanding health outcomes at fine spatial scales, iterative proportional fitting (IPF), a form of small area estimation, was applied to a fixed number of health-related variables (obesity, overweight, diabetes) taken from regionalized 2019 survey responses (n = 5474) from the Idaho Behavioral Risk Factor Surveillance System (BRFSS). Using associated county-level American Community Survey (ACS) census data, a set of constraints, which included age categorization, race, sex, and education level, were used to create county-level weighting matrices for each variable, for each of the seven (7) Idaho public health districts. Using an optimized modeling construction technique, we identified significant constraints and grouping splits for each variable/region, resulting in estimates that were internally and externally validated. Externally validated model results for the most populated counties showed correlations ranging from .79 to .85, with p values all below .05. Estimates indicated higher levels of obesity and overweight individuals for midsouth and southwestern Idaho counties, with a cluster of higher diabetes estimates in the center of the state (Gooding, Lincoln, Minidoka, and Jerome counties). Alternative external sources for health outcomes aligned extremely well with our estimates, with wider confidence intervals in more rural counties with sparse populations.

Explaining adult obesity, severe obesity, and BMI: Five decades of change

Obesity rates have increased across all segments of society since the late 1970s, but the reason behind population-level increases in body weight remains unclear. We used the 1971-2020 NHANES data to examine whether the observed trend in obesity prevalence is attributable to changing public health behaviors (i.e., intracohort change) or changing publics (i.e., cohort replacement). We partitioned total change in mean BMI, and rates of obesity and severe obesity, into its IC and CR components using linear and algebraic decomposition methods. We found that the IC mechanism (i.e., broad sectors of individuals changing) plays a dominant role in the overall increase in mean BMI, and obesity and severe obesity prevalence. Birth cohort membership (i.e., the CR mechanism) is also influencing mean BMI, and rates of obesity and severe obesity, but in differing ways. Specifically, the large positive IC and the small positive CR effects are amplifying one another, thus creating a steep increase in the observed rates of severe obesity. Conversely, the large positive IC effect is offset by a small negative CR effect, which created a more gradual rise in mean BMI and rates of obesity. Furthermore, we computed total change for models that entered separately sociodemographic, lifestyle, nutritional, and physical activity measures to estimate differences in mean BMI, and rates of obesity and severe obesity, among cohorts and time periods. Adjustment for all the compositional differences among the cohorts during the study period indicate that a combination of a more pronounced IC and a less pronounced CR drove the observed increase in mean BMI, and rates of obesity and severe obesity. Thus, "universal prevention" (i.e., entire community) strategies for healthy weight promotion may need to be combined with "selective prevention" (i.e., at-risk groups) and/or "targeted prevention" (i.e., at-risk individuals) approaches in order to reverse the obesity epidemic.

Strategic Directions in Preventive Intervention Research to Advance Health Equity

As commissioned by the Society for Prevention Research, this paper describes and illustrates strategic approaches for reducing health inequities and advancing health equity when adopting an equity-focused approach for applying prevention science evidence-based theory, methodologies, and practices. We introduce an ecosystemic framework as a guide for analyzing, designing, and planning innovative equity-focused evidence-based preventive interventions designed to attain intended health equity outcomes. To advance this process, we introduce a health equity statement for conducting integrative analyses of ecosystemic framework pathways, by describing the role of social determinants, mechanisms, and interventions as factors directly linked to specific health equity outcomes. As background, we present health equity constructs, theories, and research evidence which can inform the design and development of equity-focused intervention approaches. We also describe multi-level interventions that when coordinated can produce synergistic intervention effects across macro, meso, and micro ecological levels. Under this approach, we encourage prevention and implementation scientists to apply and extend these strategic directions in future research to increase our evidence-based knowledge and theory building. A general goal is to apply prevention science knowledge to design, widely disseminate, and implement culturally grounded interventions that incrementally attain specific HE outcomes and an intended HE goal. We conclude with recommendations for conducting equity-focused prevention science research, interventions, and training.

Investigating implementation of school health policies through a health equity lens: A measures development study protocol

Background

School-based policies that ensure provision of nutrition, physical activity, and other health-promoting resources and opportunities are essential in mitigating health disparities among underserved populations. Measuring the implementation of such policies is imperative to bridge the gap between policy and practice. Unfortunately, limited practical, psychometrically strong measures of school policy implementation exist. Few available explicitly focus on the issues of equity and social justice as a key component of implementation, which may result in underassessment of the equity implications of policy implementation. The purpose of this study is to develop equity-focused measures in collaboration with practitioners, researchers, and other key implementation partners that will facilitate evaluation of policy implementation determinants (i.e., barriers and facilitators), processes, and outcomes.

Methods

We will actively seek engagement from practitioners, researchers, and advocacy partners (i.e., stakeholders) who have expertise in school health policy throughout each phase of this project. We propose a multi-phase, 1-year project comprising the following steps: (1) selection of relevant constructs from guiding frameworks related to health equity and implementation science; (2) initial measure development, including expert feedback on draft items; (3) pilot cognitive testing with representatives from key target populations (i.e., school administrators, teachers, food service staff, and students and parents/guardians); and (4) measure refinement based on testing and assessment of pragmatic properties. These steps will allow us to establish initial face and content validity of a set of instruments that can undergo psychometric testing in future studies to assess their reliability and validity.

Discussion

Completion of this project will result in several school policy implementation measurement tools which can be readily used by practitioners and researchers to evaluate policy implementation through a health equity lens. This will provide opportunities for better assessment and accountability of policies that aim to advance health equity among school-aged children and their families.

Psychosocial predictors of problematic eating in young adults who underwent adolescent bariatric surgery

Introduction

This study examined problematic eating and eating-related psychopathology among young adults who underwent adolescent bariatric surgery including concurrent and prospective associations with psychosocial factors and weight change.

Methods

VIEW point is a 6-year follow-up study within a prospective observational study series observing adolescents with severe obesity who had bariatric surgery (n = 139) or who presented to nonsurgical lifestyle modification programs (n = 83). Participants completed height/weight measurements, questionnaires, and diagnostic interviews. Regression analyses compared problematic eating across groups and examined Year 6 correlates (i.e., psychosocial factors and weight change) and baseline predictors (i.e., psychosocial factors) of eating-related psychopathology.

Results

Compared to the nonsurgical group, the surgical group reported lower eating-related psychopathology, objective binge eating, and grazing at Year 6. While chewing/spitting out and vomiting for weight/shape-related reasons were very infrequent for the surgical group, self-induced vomiting for other reasons (e.g., avoid plugging) was more common. For the surgical group, lower self-worth, greater internalizing symptoms, and higher weight-related teasing in adolescence predicted increased eating-related psychopathology in young adulthood. Year 6 eating-related psychopathology was concurrently associated with lower percent weight loss for the surgical group and greater percent weight gain for the nonsurgical group.

Conclusion

Undergoing adolescent bariatric surgery appears to afford benefit for problematic eating and eating-related psychopathology. Current findings suggest that the clinical intervention related to problematic eating and associated psychosocial concerns may be needed for young adults with obesity, regardless of surgical status.

Feasibility of a Theory-Based, Online Tailored Message Program to Motivate Healthier Behaviors in College Women

We aimed to test the feasibility of an online survey and tailored message program in young women. Recruited from college campuses, women (n = 189) completed an online survey assessing preference for and behaviors toward diet and physical activity as well as theory-based influencers of these behaviors (knowledge/information, motivation, and confidence). Health messages were tailored to the participant’s survey responses and learning style to address misconceptions and motivate or reinforce healthy physical activity and dietary behaviors. Most women reported the survey as relevant (92%) and useful for reflecting on their health (83%), with survey responses variable in level of nutrition and physical activity knowledge, motivation, and confidence. Each woman received four tailored messages—most reported the messages as relevant (80%) and learning new information (60%). Across all messages, nearly half of the participants (~48%) reported willingness to try or maintain healthier behaviors and confidence in their ability. Body size discrepancy and dietary restraint had small effects message responses of information learned, and the motivation and confidence in trying healthier behaviors. In summary, these data support the feasibility of this online tailored message program. The college women found the tailored message program acceptable and useful to motivate healthier behaviors. The findings provide direction for behaviorally focused interventions to improve dietary and physical activity behaviors.

The Multi-Caregiver Role and Its Relationship to Behavioral Adherence and Weight Among Treatment Engaged Black Women

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 (β = -.56 [SE = .27], P < .05) and a trend towards weight gain (β = .36, [SE = .19], P = .07). Greater multiple caregiver barriers score predicted a decrease in fruit/vegetable intake (β = -.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.

Responding to Health Disparities in Behavioral Weight Loss Interventions and COVID-19 in Black Adults: Recommendations for Health Equity

COVID-19 has disproportionately impacted Black adults with high prevalence and mortality rates. Obesity is a central factor in the severity of COVID-19 and related treatment. Behavioral weight loss interventions are an efficacious treatment for obesity, but consistently, Black men and women are minimally represented, and weight loss outcomes are less than clinically significant thresholds. This commentary draws parallels between COVID-19 racial disparities, disparate obesity rates, weight loss treatment outcomes, and underlying systemic racial context. This paper also indicates paths forward to address racialized societal norms in obesity treatment to advance health equity in obesity and reduce acute disease vulnerability. Recommendations for behavioral medicine practice and policy include (1) expanding the research lens to prioritize Black scholars and institutions to generate innovative research questions, (2) creating trustworthy relationships with Black community members to bolster recruitment and retention, (3) employing qualitative methods to facilitate better intervention design and uncover influences of racialized social context, (4) centering Black adults in weight loss interventions, and (5) using multilevel approaches that integrate policy into interventions. Moving forward, this commentary aims to make plain the multilayered form and function of racism, its impact on COVID-19 and obesity, and offer pathways to improve behavioral weight loss interventions that can produce more equitable outcomes.

Giving "prescriptions" for paediatric weight management follow-up in primary care

The American Academy of Paediatrics recommends that primary care paediatricians "prescribe" follow-up for weight management between well child checks. We sought to describe rates and predictors of prescribed and actual clinic attendance for weight management in primary care in a predominantly low-income population. A chart review was performed at a large, hospital-based, primary care clinic, where a treatment algorithm for obesity exists. Eligible children were 6 to 12 years of age with a body mass index (BMI) ≥85th percentile and seen for a well child check in 2014. Primary outcomes were the physician prescribing follow-up in primary care and the patient returning for weight management. Multivariable logistic regression was used to identify predictors of prescribing follow-up and predictors of return. Participants included 1339 patients: mean age 9 years (SD: 1.8 years); 53% female; 79% Black; 89% Medicaid-insured; 56% with an obese BMI (vs overweight). Twenty-seven percent of patients were prescribed follow-up in primary care, of which 13% returned (only 4% of the original sample). The odds of the physician prescribing follow-up were greater if the child had obesity (vs overweight), was older, female or non-Medicaid insured. Older and non-Black patients had greater odds of returning. Patients prescribed follow-up within 2 months or less (vs 3-6 months) were also more likely to return (aOR 2.66; CI: 1.34, 5.26). Rates of prescription for weight management in primary care are low and few patients return, even when follow-up is prescribed. Prescribing follow-up at shorter intervals from the index visit (≤ 2 months) may improve patient return.

Framing Food Access: Do Community Gardens Inadvertently Reproduce Inequality?

BACKGROUND

Alternative food programs have been proposed as solutions to food insecurity and diet-related health issues. However, some of the most popular programs-farmers markets and community-supported agriculture-overwhelmingly serve White and upper-middle-class individuals, exacerbating food security and health disparities. One explanation for the mismatch is the way in which alternative food programs are framed: Language used to encourage participation may reflect priorities of upper-middle-class and White populations who create and run these programs while lacking resonance with food-insecure populations. This literature, however, lacks consideration of how lower-cost, more participatory programs-community gardens-are framed. We therefore explore the framing of community gardens through a quantitative content analysis of the descriptions, missions, and goals provided by community garden managers across Minnesota (N = 411).

RESULTS

Six frames were consistently present in the community garden statements: greater good, community orientation, healthy food access, food donation, self-empowerment, and symbolic food labels. Greater good and community orientation were significantly more likely to be used than any other frames.

CONCLUSIONS

Taken together, our findings suggest that community gardens may be welcoming toward a diversity of participants but still have room to improve the inclusivity of their frames. The common use of a community orientation suggests the unique ability of community gardens among alternative food programs to benefit Black, Latino, and working-class populations. However, the most common frame observed was "greater good," suggesting one mechanism through which community gardens, like other types of alternative food programs, may be reproducing inequality through alienation of food-insecure populations.
