This study aimed to evaluate the association between the consumption of ultra-processed foods (UPF) and the anthropometric profile of lactating women in situations of socioeconomic vulnerability. In this cross-sectional study, we collected socioeconomic and health data, food consumption information, and anthropometric measurements of lactating women between 30 and 150 days postpartum. Food consumption was evaluated using a 24-h dietary recall adapted to UPF through the Nova classification, and the anthropometric profile was assessed according to postpartum weight retention (kilograms (kg)), current body mass index (BMI) (kg/m), and measurements of body perimeters (centimeters (cm)) and skinfolds (millimeters (mm)). Participants were grouped according to the proportion of dietary energy derived from UPF (tertile 1-2 vs. tertile 3). Adjusted linear regression models were employed to analyze associations. The study population consisted of 124 lactating women, most of had low income (102 (82.3%)) and lowest level of education (113 (91.1%)), and the average proportion of dietary energy from ultra-processed foods (UPF) was 25% (95% confidence interval (95% CI) 0%-76%). We found a positive association between the proportion of dietary energy from UPF and postpartum weight retention ( = 3.75, 95% CI 1.40-6.10, < 0.002). Our findings suggest that a greater proportion of UPF in the diet of lactating women is related to postpartum weight retention, which reinforces the need for actions aimed at reducing UPF consumption during lactation. Our results require confirmation from future, more rigorous studies.
本研究旨在评估在社会经济脆弱状况下，超加工食品（UPF）的摄入量与哺乳期妇女身体测量指标之间的关联。在这项横断面研究中，我们收集了产后30至150天哺乳期妇女的社会经济和健康数据、食物消费信息以及身体测量数据。通过诺瓦分类法对24小时饮食回忆进行调整以评估食物消费情况，该分类法适用于超加工食品，同时根据产后体重保留量（千克（kg））、当前体重指数（BMI）（kg/m²）、身体周长测量值（厘米（cm））和皮褶厚度（毫米（mm））来评估身体测量指标。参与者根据超加工食品提供的膳食能量比例进行分组（三分位数1 - 2与三分位数3）。采用调整后的线性回归模型来分析关联。研究人群包括124名哺乳期妇女，其中大多数收入较低（102人（82.3%））且教育水平最低（113人（91.1%）），超加工食品提供的膳食能量平均比例为25%（95%置信区间（95%CI）0% - 76%）。我们发现超加工食品提供的膳食能量比例与产后体重保留之间存在正相关（β = 3.75，95%CI 1.40 - 6.10，P < 0.002）。我们的研究结果表明，哺乳期妇女饮食中超加工食品比例越高，与产后体重保留有关，这强化了在哺乳期采取旨在减少超加工食品消费的行动的必要性。我们的结果需要未来更严谨的研究加以证实。
