摘要
这项横断面研究调查了巴西素食成年人（n = 925）的超加工食品（UPF）消费量及其与超重的关系。数据是通过自填式结构化在线问卷收集的。超重率为 26.2%（95% 置信区间 [CI] 23.3-29.1）。UPF消耗量的中位数为1.8次/天（1.0-3.1四分位距[IQR]）。多变量广义线性模型发现，随着UPF摄入量（按五分位数分类）的增加，超重概率也会增加（患病率比[PR] 1.08 [95%CI 1.01-1.17]）。此外，年龄（PR 1.03 [95%CI 1.02-1.04]）、每天在外进食三餐以上（PR 1.56 [95%CI 1.08-2.23]）、素食时间（PR 0.98 [95%CI 0.97-0.99]）和居住在全国最富裕地区（PR 1.35 [95%CI 1.06-1.71]）也与超重有关。虽然素食者的平均 UPF 摄入量和超重率低于普通人群，但 UPF 暴露仍可能导致体重过度增加或维持体重。这项研究支持将《巴西膳食指南》推广到素食人群。

Are vegetarians' diets inherently healthy? Ultra-processed food consumption is associated with overweight among vegetarians: the brazilian survey on the health, food, and nutrition of vegetarians.
This cross-sectional study investigated ultra-processed food (UPF) consumption and its association with overweight among Brazilian vegetarian adults (n = 925). Data were collected using a self-administered structured online questionnaire. The prevalence of overweight was 26.2% (95% confidence interval [CI] 23.3-29.1). The median UPF consumption was 1.8 times/day (1.0-3.1 interquartile range [IQR]). The multivariable generalised linear model identified an increase in overweight probability as the UPF intake - categorised into quintiles - increases (prevalence ratio [PR] 1.08 [95%CI 1.01-1.17]). Additionally, age (PR 1.03 [95%CI 1.02-1.04]), eating more than three meals/day away from home (PR 1.56 [95%CI 1.08-2.23]), duration of vegetarianism (PR 0.98 [95%CI 0.97-0.99]) and living in the wealthiest regions in the country (PR 1.35 [95%CI 1.06-1.71]) were associated with overweight. Although vegetarians have a lower average UPF intake and overweight prevalence than the general population, UPF exposure can still lead to excessive weight gain or maintenance. This study endorses generalising the Brazilian Dietary Guidelines for the vegetarian population.
