Social environment perception and associations with overweight in the city of Porto Alegre, Brazil

Abstract: The prevalence of overweight in Brazilian adults has grown in recent years. There is evidence indicating that environmental factors, especially social characteristics, may be involved in the aetiology of overweight, but few studies have investigated this association adequately. The main objective of this study was to identify residents’ perception of their social environment (social cohesion, security and violence) and assess its relationship with overweight in a central area of Porto Alegre, Brazil.

“…The analysis is part of a larger epidemiological study titled ‘Social and Environmental Determinants of Food and Nutrition: An Ecosocial Approach’. This comprehensive study was devised to assess how ecosocial epidemiology can serve as a basis for exploring the social and environmental factors influencing food and nutrition, as well as their associated disparities, within an adult population residing in the central area of a major city in southern Brazil ( 22 , 23 ) . The sample size was initially determined to investigate the relationship between income and obesity.…”

“…The following parameters were adopted for sample size calculation: 95 % confidence level, 80 % statistical power, 1·35 relative risk, unexposed ratio: exposed 1:2, overweight prevalence among the unexposed 43 % and exposed 58 %. A sample of 419 individuals was estimated ( 22 ) . For this specific study, Kline’s recommendation stipulated a minimum of 200 cases for conducting structural equation modeling analysis ( 24 ) .…”

“…The sample size (n = 400) was calculated for the main objective of the broader study (Social and environmental determinants of food and nutrition: an ecosocial approach) (31) . For the present study, this sample size had the power to identify dietary patterns according to the criteria proposed by Hair et al (32) (five individuals per food item included in the principal component analysis and had 80% statistical power to detect effect https://doi.org/10.1017/S0007114522001969 Published online by Cambridge University Press Accepted manuscript sizes of approximately 0.12 in the prevalence ratios (PRs) for the association between food environment levels (exposure) and high consumption of dietary patterns (outcomes).…”
