The objective of this study is to assess changes in the dimensions of the food system and consumption associated with body weight variations during the first month's lockdown in Peruvian adults in Metropolitan Lima.
A cross-sectional study conducted during the first months of lockdowns in Peru. 694 adults completed a web-based survey about changes experienced in the process of acquiring food during lockdown, changes in their intake and self-perceived body weight. A multinomial logistic regression analysis was conducted to evaluate the factors associated with changes in body weight.
Weight gain was perceived in 38% of the participants and 22.8% perceived weight loss. 39.2% did not perceive changes in their weight. Risk factors for body weight gain were increased alcohol consumption (OR=4.510, 95% CI 1.764 to 11.531) and decreased fruit consumption (OR=2.129, 95% CI 1.290 to 3.515), while decreasing cereal intake (OR=0.498, 95% CI 0.269 to 0.922) and choosing nutritious food as a driver for purchase (OR=0.512, 95% CI 0.320 to 0.821) were found to be protective against gaining weight. Decreasing food intake during the pandemic (OR=2.188, 95% CI 1.348 to 3.550) and having to miss important foods (OR=2.354, 95% CI 1.393 to 3.978), were associated with weight loss.
During confinement, weight gain was mostly associated with food consumption and personal food system factors. Meanwhile, weight loss was associated with external food system factors.
本研究的目的是评估秘鲁利马大都会成年人群在首次封锁的第一个月期间，食物系统和消费方面与体重变化相关的维度变化。
在秘鲁封锁的头几个月进行了一项横断面研究。694名成年人完成了一项基于网络的调查，内容涉及封锁期间获取食物过程中所经历的变化、摄入量的变化以及自我感知的体重变化。进行了多项逻辑回归分析，以评估与体重变化相关的因素。
38%的参与者感觉体重增加，22.8%感觉体重减轻。39.2%的人未感觉到体重变化。体重增加的风险因素包括酒精摄入量增加（比值比=4.510，95%置信区间1.764至11.531）和水果摄入量减少（比值比=2.129，95%置信区间1.290至3.515），而谷物摄入量减少（比值比=0.498，95%置信区间0.269至0.922）以及选择营养食品作为购买驱动因素（比值比=0.512，95%置信区间0.320至0.821）被发现可预防体重增加。疫情期间食物摄入量减少（比值比=2.188，95%置信区间1.348至3.550）以及不得不错过重要食物（比值比=2.354，95%置信区间1.393至3.978）与体重减轻有关。
在隔离期间，体重增加主要与食物消费和个人食物系统因素有关。同时，体重减轻与外部食物系统因素有关。
