Özet:
Background: People with serious mental illness (SMI) experience marked health disparities from preventable and treatable conditions and a prevalence of overweight/obesity almost twice the general US population. The problems and proposed solutions to obesity-related morbidity in people with SMI have mainly focused on the individual level. Difficulties with healthy eating and physical activity are attributed to behavior or lifestyle factors, such as poor diet, sedentary routines, and low motivation, as well as increasing use of second generation antipsychotic medications. Larger system level factors have received limited attention in the response to this epidemic and past research has not adequately involved people with SMI in a deeper exploration of these issues. Health disparities involving the problem of obesity in people with SMI have not been considered using a human rights framework.
Methods: This dissertation used a participatory action orientation with a mixed-methods sequential explanatory model to explore the healthy equity factors that facilitate or limit clinically significant weight loss in people with SMI who are overweight or obese and participating in a 12-month, peer-led, group healthy lifestyle intervention. Study one utilized baseline data of 93 participants in the intervention arm of the parent Peer Group Lifestyle Balance study. Quantitative analysis was used to explore associations between the predictor variable of food security at baseline and the outcome variable of 6-month weight change. Studies two and three were developed through a participatory Photovoice project with 8 participant co-researchers. Study two explored the lived experience of healthy eating and physical activity through 7 weekly sessions with the co-researchers consisting of individual photo-elicitation and group discussion of photos and captions. Study three explored the co-researchers experience of presenting at four varied community events.
Results: The results of the quantitative analysis revealed that 76.2% percent of the sample reported some level of food insecurity, 22.6% with marginal food security, 28.6% with low food security, and 25.0% with very low food security. The mean weight change at 6 months was --2.86 pounds ( SD = 13.67) with a range of --47.6 to 33.0. At six months, 65% of the total sample had a weight lower than their baseline weight. The association between metformin use and diagnosis of diabetes with weight change was significant with the metformin group losing a mean of 6.7lbs vs 0.3lbs in intervention participants not taking metformin. The analysis of the main effect for baseline food security on weight change between baseline and 6 months approached significance (F (2, 81) = 3.075, p =.052, partial eta 2 = .071). In the Photovoice project, the eight co-researchers selected a total of 33 photos and captions to represent their experience and organized the photos into five themes: 1) Corner stores in our neighborhood, 2) Challenges to healthy eating and exercise, 3) Healthy eating ideas with limited supplies, 4) Exercise: Challenges and options, and 5) Recovery: Body, mind, and spirit. The themes from the photographs reflected two overarching themes: structural barriers and overcoming structural barriers. Four overlapping themes emerged from the analysis of the post-advocacy presentations: 1) Empowerment, 2) Influence, 3) Barriers to participation, and 4) The system.
Conclusion: The strengths of this study are grounded in the mixed-methods exploration of the impact of the social determinants of health on healthy eating and physical activity in a highly marginalized population with significant health disparities resulting in part from obesity-related conditions. The human rights framework provides an organizing lens to understand the findings of this study.
The qualitative findings provided concrete explanations of the quantitative findings. The Adult Food Security Survey revealed a 76% rate of any level of food insecurity in the sample. Fifty-four percent of the sample reported low or very low food security, higher than the national average of 12.3% (U.S. Department of Agriculture, 2015). The main effect of food security on 6-month weight change approached significance. Documenting this rate of food insecurity in the population is a critical finding and suggests many people with SMI are not achieving the right to food, despite living in supportive housing settings and receiving Supplemental Nutrition Assistance Program (SNAP) benefits. The reasons for this inequality are complex and the Photovoice project described in Chapter 3 provides some insights into this situation from the population itself. The high cost of poor quality food available in urban corner stores and fast food establishments as well as the cost of transportation out of the neighborhood contribute directly to food insecurity. The use of food pantries, with variable food quality is a consequence of food insecurity and limited SNAP benefits in the population. These situations are a threat not just to the right to healthy food, but the right to health itself. (Abstract shortened by ProQuest.).
