The purpose of this article was to investigate the association of food environment variables with Body Mass Index (BMI), excess weight and obesity. This was a cross-sectional study determining the presence or absence of food establishments within a 100-m buffer zone from each sampled household. Individuals aged 18 years and older living in the urban area of Rio Grande, RS State, Brazil, in 2016, were considered eligible. A total of 1,139 individuals, with an average age of 46.5 years (SD 17.1), residing in the household for more than one year, were selected as a representative sample of the population. The mean BMI of study participants was 27.0 kg/m (SD 4.8), and the prevalence of excess weight and obesity was 61.6% (95%CI: 58.9; 64.3) and 23.7% (95%CI: 21.3; 26.1), respectively. Living near a convenience store was associated with a higher BMI and a higher likelihood of being above normal weight and obese. In contrast, living near a restaurant was associated with a lower BMI and a lower likelihood of being above normal weight and obese. In addition, participants who lived close to fruit shops had lower BMI and a lower likelihood of being above normal weight. Concluding few associations were found between food environment and the health-related outcomes. Proximity to food establishments does not seem to significantly affect BMI, excess weight and obesity in the studied population.
本文旨在研究食物环境变量与体重指数（BMI）、超重和肥胖之间的关联。这是一项横断面研究，确定每个抽样家庭周围100米缓冲区内是否存在食品经营场所。2016年居住在巴西里约格兰德州里奥格兰德市区、年龄在18岁及以上的个体被视为符合条件。总共1139名个体，平均年龄46.5岁（标准差17.1），在该家庭居住超过一年，被选为该人群的代表性样本。研究参与者的平均BMI为27.0kg/m（标准差4.8），超重和肥胖的患病率分别为61.6%（95%置信区间：58.9；64.3）和23.7%（95%置信区间：21.3；26.1）。住在便利店附近与较高的BMI以及超重和肥胖的较高可能性相关。相比之下，住在餐馆附近与较低的BMI以及超重和肥胖的较低可能性相关。此外，住在水果店附近的参与者BMI较低，超重的可能性也较低。结论是在食物环境与健康相关结果之间发现的关联较少。在所研究的人群中，靠近食品经营场所似乎不会显著影响BMI、超重和肥胖。
