Intrapersonal Factors: involve an individual's beliefs, attitudes, and knowledge about a health condition.

Lifestyle Causal Beliefs about Obesity

when categorized as ‘some'/‘a lot', 94% of participants held not exercising causal beliefs, 95% held overeating causal beliefs, 90% held eating certain types of food causal beliefs, 70% held chemicals in food causal beliefs, and 41% held smoking causal beliefs about obesity, compared to the 69% who held genetic causal beliefs about obesity. There were few associations between lifestyle causal beliefs about obesity and any of the sociodemographic or health-related characteristics assessed.

Genetic Causal Beliefs about Obesity-Related Diseases

Overall, 82% of participants held genetic causal beliefs about type 2 diabetes (fig. 2), 79% about heart disease (fig. 3) and 75% about cancer (fig. 4), when categorized as ‘some/a lot.' table 3 shows that there were very few associations with participant sociodemographic or health-related characteristics.(all threse from https://www.karger.com/Article/Fulltext/343793)

This study is based on the Ecological Systems Theory and Family and Community Systems perspectives, which emphasize the need to consider the effects of individual, family, community, and societal factors on health and social outcomes (Bronfenbrenner & Morris, 1988; Campbell, Hesketh, & Davison, 2010; Elder et al., 2007; Fulkerson et al., 2015; Novilla, Barnes, De La Cruz, Williams, & Rogers, 2006; Valente, 2012).

This study contributes to the literature in several ways and emphasizes that peers and families are important sources of influence when it comes to healthy eating and choices of activities in young adolescents. Specifically, adolescents who reported a stronger connection with their family also engaged more frequently in physical activity than adolescents who reported lower familism. The benefits of targeting the family as part of lifestyle interventions are well established (Epstein, Paluch, Roemmich, & Beecher, 2007; Skelton, Buehler, Irby, & Grzywacz, 2012; St Jeor, Perumean-Chaney, Sigman-Grant, Williams, & Foreyt, 2002). The rationale underlying family-centered approaches is that modification of the youth’s environment is necessary to change and maintain children’s healthy habits. As a primary source of socialization, parents not only influence youths’ healthy lifestyle in providing access to resources and in modeling and reinforcing healthy habits, but they also provide the basis for the development of healthy peer relationships. Conceivably, stronger family connections may operate directly on young adolescents’ physical activity, but also indirectly in establishing the foundations for healthy peer relationships, which in turn promote healthier diet and a less sedentary lifestyle.

Furthermore, adolescents who reported higher PSF had a healthier diet and spent less time engaging in screen behavior than adolescents with lower peer social functioning . Findings are consistent with the protective power of friendships in other areas, such as smoking, drug and alcohol use, bullying, and other peer difficulties (Bollmer, Milich, Harris, & Maras, 2005; Fang et al., 1996; Forster, Grigsby, Bunyan, Unger, & Valente, 2015; Powers, Ressler, & Bradley, 2009). Our findings extend work in this area and suggest that helping adolescents develop healthy peer relationships may, in part, lead to healthier eating habits and protect them against a sedentary lifestyle(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6075537/)

, community,

The Healthy Weights Initiative Program is free, community-based obesity reduction program, which works on physical activity and dietary behavior. It addresses the importance of social support as a factor that played a major role in adherence to completion of HWI program. 79% of participants showed positive results in completing the program during 24 weeks(from https://www.dovepress.com/the-importance-of-community-consultation-and-social-support-in-adherin-peer-reviewed-fulltext-article-PPA#ref45).

The importance of social support

Having social support was an important factor for adherence in HWI and is supported in the literature. In a previous study, those who signed contracts experienced nearly double the weight loss of those participants who attempted to lose weight on their own(Harris MB, Bruner CG. A comparison of a self-control and a contract procedure for weight control. Behav Res Ther. 1971;9(4):347–354.). I In a third study, participants with support versus a self-motivated approach for maintaining weight loss discovered that those who received social support were 37% more likely to maintain their weight loss over 2 years(Brantley PJ, Stewart DW, Myers VH, et al. Psychosocial predictors of weight regain in the weight loss maintenance trial. J Behav Med. 2014;37(6):1155–1168.)

For example, a study to determine the benefits of social support for weight loss and maintenance recruited subjects to either participate alone or with three family members or friends. At 6-month follow-up, the study found participants who attended with family or friends were three times more likely to maintain their weight loss after program completion than those who attended alone(Wing RR, Jeffery RW. Benefits of recruiting participants with friends and increasing social support for weight loss and maintenance. J Consult Clin Psychol. 1999;67(1):132–138.)

environmental, social

I would like to present how environmental factors impact obesity populations. Physical activity plays an essential role in preventing becoming obese or overweight. The data from the Miami Matter website showed there were 30.7% of adults are sedentary, and the value didn't reach the health people target of 2030 (21.2%). According to resent study shows Blighted and vacant urban land is a widespread and potentially risky environmental condition encountered by millions of people every day. About 15% of the land in US cities is deemed vacant or abandoned, translating into an area roughly the size of Switzerland: over 3 million hectares of otherwise beneficial spaces remain neglected. Urban residents, especially in low-income neighborhoods, point to these spaces as primary threats to their health and safety. Cities continue to seek meaningful, evidence-based interventions for remediating vacant land. Standardized processes for the restoration of vacant urban land were experimentally tested on a citywide scale and found to significantly reduce gun violence, crime, and fear and increase physical activity(https://www.pnas.org/doi/10.1073/pnas.1718503115)

policy determinants

looks at rules regulations and policies. The places we work, live, and learn play are important role on one’s health.

The two studies to examine the relationship between state PE and recess-related laws on youth obesity reported mixed results. Both analyses linked data on state laws obtained from the NCI’s PERSPCS [48, 49] with individual-level, cross-sectional data for 10–17 year olds obtained from the NSCH. Riis and colleagues found that the odds of youth obesity was higher in states: (1) with stronger laws governing assessment of health-related fitness at the elementary and middle school levels and recess time requirements for elementary schools; and (2) whose laws were strengthened between 2003 and 2006 for physical educator staff qualifications (at the elementary and middle school levels) and PE curriculum standards (across all three grade levels) [49]. Although these findings seem contradictory to the goals of the policies, the authors concluded that states with larger youth obesity problems enacted stronger PE-related laws. Kim did not find any association between the overall PERSPCS policy scores at the state level and individual level youth obesity(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3916087/)

Also, Implementing School-Based Policies to Prevent Obesity: Cluster Randomized Trial. Healthier school environments can benefit students, and school wellness policies may result in meaningful enhancements. Schools participating in federal child nutrition programs must implement wellness policies as mandated by law.

Analyses followed intention-to-treat principles, with planned secondary analyses (conducted 2016-2018). Students at schools randomized to receive support for nutrition policy implementation had healthier BMI trajectories over time (F=3.20, p=0.02), with a greater magnitude over time and cumulatively significant effects 3 years post-intervention (β=-2.40, p=0.04). Overall, students at schools randomized to receive the nutrition intervention had an increase in BMI percentile of <1%, compared with students in other conditions, whereas BMI percentile increased 3%-4%. There was no difference in student BMI between those in schools with and without physical activity policy implementation. Examining behavioral correlates in eighth grade, students at schools randomized to the nutrition condition consumed fewer unhealthy foods and sugar-sweetened beverages, and ate less frequently at fast-food restaurants (all p<0.03).( https://pubmed.ncbi.nlm.nih.gov/30573151/)
