Ecological studies are essential for understanding the environment-diet relationship. The purpose of this study was to describe environmental conditions and their relationship with fruit and vegetable (FV) consumption among Brazilian public health service users in the city of Belo Horizonte. We evaluated food stores contained within 1600 m buffer zones at 18 Health Academy Programme sites, from 2013 to 2014. Variables at the community (density, proximity and type) and the consumer (sectional location of FV; availability, quality, variety, price and advertising of FV and ultra-processed foods) nutrition environment were measured by direct observation, while aggregate data from users (income and FV consumption) were obtained by interview. Data were analysed using the Kernel intensity estimator, average nearest neighbour value and Local Moran's Index for local spatial autocorrelation. We interviewed 3414 users and analysed 336 food stores. Major geographical variations in the FV consumption were identified. Average consumption was higher (site 2A: 410.5 ± 185.7 g vs. site 4B: 311.2 ± 159.9 g) in neighbourhoods with higher income and concentration of food stores, and better index of access to healthy foods. Sites with poor FV consumption had the most stores with poor access to healthy foods (index in the first tertile, ≤ 10). In conclusion, negative characteristics of the food environment, as seen in the present study, may contribute to low FV consumption, suggesting the need for the development and consolidation of public policies aimed at creating healthy environments through built environment interventions that increase access to and consumption of healthy foods like FV.
生态研究对于理解环境与饮食之间的关系至关重要。本研究旨在描述巴西贝洛奥里藏特市公共卫生服务使用者所处的环境状况及其与水果和蔬菜(FV)消费之间的关系。我们在2013年至2014年期间评估了18个健康学院项目地点周围1600米缓冲区范围内的食品商店。通过直接观察来测量社区层面(密度、距离和类型)以及消费者层面(FV的区域位置;FV和超加工食品的可获得性、质量、种类、价格及广告宣传)营养环境的变量,同时通过访谈获取使用者的汇总数据(收入和FV消费情况)。使用核密度估计器、平均最近邻值和局部空间自相关的局部莫兰指数对数据进行分析。我们访谈了3414名使用者,并分析了336家食品商店。研究发现FV消费存在显著的地理差异。在收入较高、食品商店集中且获取健康食品指数较好的社区,平均消费量更高(2A区:410.5±185.7克,而4B区:311.2±159.9克)。FV消费量较低的地点,难以获取健康食品的商店最多(指数处于第一三分位数,≤10)。总之,本研究中所观察到的食品环境的负面特征可能导致FV消费量较低,这表明需要制定和巩固公共政策,通过旨在改善建筑环境以增加获取FV等健康食品机会并促进其消费的干预措施,来营造健康的环境。
