Overcoming weight bias: promoting physical activity and psychosocial health

Systematic realist synthesis of health-related and lifestyle interventions designed to decrease overweight, obesity and unemployment in adults

Background

Obesity and unemployment are complex social and health issues with underlying causes that are interconnected. While a clear link has been established, there is lack of evidence on the underlying causal pathways and how health-related interventions could reduce obesity and unemployment using a holistic approach.

Objectives

The aim of this realist synthesis was to identify the common strategies used by health-related interventions to reduce obesity, overweight and unemployment and to determine for whom and under what circumstances these interventions were successful or unsuccessful and why.

Methods

A realist synthesis approach was used. Systematic literature searches were conducted in Cochrane library, Medline, SocIndex, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and PsychInfo. The evidence from included studies were synthesised into Context-Mechanism-Outcome configurations (CMOcs) to better understand when and how programmes work, for which participants and to refine the final programme theory.

Results

A total of 83 articles met the inclusion criteria. 8 CMOcs elucidating the contexts of the health-related interventions, underlying mechanisms and outcomes were identified. Interventions that were tailored to the target population using multiple strategies, addressing different aspects of individual and external environments led to positive outcomes for reemployment and reduction of obesity.

Conclusion

This realist synthesis presents a broad array of contexts, mechanisms underlying the success of health-related interventions to reduce obesity and unemployment. It provides novel insights and key factors that influence the success of such interventions and highlights a need for participatory and holistic approaches to maximise the effectiveness of programmes designed to reduce obesity and unemployment.

Yoga at Every Size: A Preliminary Evaluation of a Brief Online Size-Inclusive Yoga and Body Gratitude Journaling Intervention to Enhance Positive Embodiment in Higher Weight College Women

The present pilot randomized controlled trial (RCT) evaluated the feasibility, acceptability, and preliminary efficacy of a 4-week online yoga and body gratitude journaling intervention for strengthening positive embodiment among racially-diverse higher weight college women. Seventy-five participants were initially randomized to either the yoga condition (n = 36) or to a wait-list control (n = 39). Participants completed measures of positive and negative body image, weight bias internalization, self-compassion, drive for leanness, and physical activity acceptance at both baseline and post. Preliminary results among the 42 analyzed completers (mean age = 20.9, SD = 2.4; 30% Black or African American) revealed acceptable feasibility given the low-intensity nature of the intervention reflected in a 36% attrition rate. Self-reported adherence was strong for the yoga component with 81% of participants indicating that they practiced with the videos ≥3–4 times per week as suggested. Although 71% reported completing the body gratitude journal ≥1–2 times per week, daily adherence was minimal. Acceptability was also high among participants randomized to the yoga condition as indicated by 86% expressing at least moderate levels of satisfaction with the overall program. Qualitative feedback from participants further supported the acceptability of the program and pointed to important areas in further refining the protocol in the future. Preliminary efficacy was supported by significant reductions in internal body shame and gains in body appreciation, functional body appreciation, functional body satisfaction, functional body awareness, and behavioral commitment to physical activity engagement among the yoga vs. wait-list control participants. These promising findings once replicated in larger, higher-powered trials may have important implications for extending the reach and accessibility of mind-body wellness practices like yoga to benefit racially-/ethnically-diverse college women of higher weight. This research is further responsive to the growing need for efficacious remotely-delivered, and scalable behavioral health interventions in the ongoing era of the COVID-19 pandemic. However, additional research is warranted to explore ways of enhancing engagement of participants with lower levels of positive embodiment and to further incentivize the journaling component of the intervention.

Experiences of Size Inclusive Physical Activity Settings Among Women With Larger Bodies

Purpose: Size inclusive physical activity settings may help mitigate the impact of physical activity-related weight stigma. In this interpretive description study, we aimed to understand how women with larger bodies experienced size inclusive physical activity settings. The study was informed by a settings-based approach to health promotion. Method: We interviewed nine women with larger bodies who participated in size inclusive physical activity and used an inductive approach to analyze the data. Findings: At the individual level, size inclusion was experienced as an enhancement of well-being, self-worth, and belonging. This was closely tied to the interpersonal level, whereby weight-neutral practices used by fitness instructors and lack of judgment from other exercisers contributed to experiences of size inclusion. At the organizational level, the organization's culture, marketing, programs, and physical spaces could enhance or limit inclusion and participation. However, weight stigma was prevalent in women's experiences outside the physical activity setting. Conclusion: We provide recommendations to improve size inclusion in physical activity settings.

The weight of words: Discursive constructions of health in weight-neutral peer-reviewed journal articles

Weight-neutral approaches to health, like the Health at Every Size® (HAES®) approach arose in response to emerging evidence showing the negative health consequences of weight-focused approaches through the effects of stigma and marginalization in many settings, including healthcare. While the discourses of dominant 'weight-normative' approaches are well-researched and described, little is known about how language and discourse is creating certain 'truths' about weight-neutral approaches. The aim of this study was to explore how academic discourses create truths about weight-neutral approaches to health. A discourse analysis of 63 academic journal articles was conducted. We found that the language used in academic literature is creating confusing and contradictory messages about weight and weight-neutral approaches to health (like the HAES® approach) through: (i) the continued use of stigmatising and normative labels like 'overweight' and 'obese', (ii) paradoxical language like 'flexible restraint', and (iii) a focus on individual responsibility and blame for health and weight without acknowledgement of broader societal and systemic factors. More research is needed to characterize weight-neutral approaches and develop a clearer framework for researchers wishing to engage with the weight-neutral paradigm of health.

Is weight stigma associated with physical activity? A systematic review

OBJECTIVE

Weight stigma is associated with impaired health, attributed in part to reductions in health-promoting behaviors. This review analyzed evidence of the association between weight stigma and physical activity (PA) in adults and youth.

METHODS

Three databases were searched for terms related to weight stigma and PA. Eligible studies reported the quantitative association between at least one measure of weight stigma and one behavioral measure of PA.

RESULTS

A total of 38 studies met eligibility criteria. Of the 29 studies of adults, 3 used objective PA measures, and 79% used an observational, cross-sectional design. Findings of the relationship between weight stigma and PA were mixed. Everyday weight discrimination and internalizing weight stigma were associated with reduced PA in most studies. Several studies found indirect, and not direct, effects of weight stigma on PA when analyses included other individual-level factors. In the nine studies of youth, two used objective PA measures, all were observational, and only one study was longitudinal. Most youth studies found a relationship between weight-based teasing and reduced PA.

CONCLUSIONS

Weight teasing, everyday discrimination, and internalization were associated with reduced PA. However, associations were inconsistent and often indirect. Future studies should include objective PA measures with larger samples and longitudinal assessments.

Internalized weight stigma moderates eating behavior outcomes in women with high BMI participating in a healthy living program

Weight stigma is a significant socio-structural barrier to reducing health disparities and improving quality of life for higher weight individuals. The aim of this study was to examine the impact of internalized weight stigma on eating behaviors after participating in a randomized controlled trial comparing the health benefits of a weight-neutral program to a conventional weight-management program for 80 community women with high body mass index (BMI > 30, age range: 30-45). Programs involved 6 months of facilitator-guided weekly group meetings using structured manuals. Assessments occurred at baseline, post-intervention (6 months), and 24-months post-randomization. Eating behavior outcome measurements included the Eating Disorder Examination-Questionnaire and the Intuitive Eating Scale. Intention-to-treat linear mixed models were used to test for higher-order interactions between internalized weight stigma, group, and time. Findings revealed significant 3-way and 2-way interactions between internalized weight stigma, group, and time for disordered and adaptive eating behaviors, respectively. Only weight-neutral program participants with low internalized weight stigma improved global disordered eating scores. Participants from both programs with low internalized weight stigma improved adaptive eating at 6 months, but only weight-neutral program participants maintained changes at follow-up. Participants with high internalized weight stigma demonstrated no changes in disordered and adaptive eating, regardless of program. In order to enhance the overall benefit from weight-neutral approaches, these findings underscore the need to incorporate more innovative and direct methods to reduce internalized weight stigma for women with high BMI.
