This study investigated the association between ultraprocessed food consumption and excess body weight in a Swiss nationally representative study.
Data stem from the cross-sectional Swiss National Nutrition Survey menuCH (n = 2,057). Dietary information was collected with 24-hour dietary recalls, and food items were categorized into non-ultraprocessed or ultraprocessed using the NOVA food classification system. The following three excess body weight indicators were considered: BMI, waist circumference (WC), and a BMI-WC composite outcome. Multinomial logistic regression models stratified by sex were fitted.
Women in the highest quintile of ultraprocessed food weight proportion had significantly higher odds of having obesity (odds ratio [OR] 3.01, 95% CI: 1.48-6.11), having abdominal obesity (OR 2.69, 95% CI: 1.43-5.05), and being in the highest category of the BMI-WC composite outcome (OR 3.28, 95% CI: 1.59-6.77). No relevant associations were observed in men.
Ultraprocessed food weight proportion was strongly and dose-dependently associated with excess body weight in women but not in men. Further studies are required to elucidate potential mechanisms behind this association. Increasing evidence of the detrimental effect of ultraprocessed food consumption on health stresses the need to consider these products in future public health strategies.
在一项瑞士全国代表性研究中，调查超加工食品消费与超重之间的关联。
数据来源于横断面的瑞士国家营养调查menuCH（n = 2,057）。通过24小时饮食回顾收集饮食信息，并使用NOVA食品分类系统将食品项目分为未加工或超加工食品。考虑了以下三个超重指标：体重指数（BMI）、腰围（WC）和BMI-WC综合结果。拟合了按性别分层的多项逻辑回归模型。
超加工食品重量比例最高的五分位数中的女性患肥胖症的几率显著更高（优势比[OR] 3.01，95%置信区间：1.48 - 6.11），患腹部肥胖症的几率（OR 2.69，95%置信区间：1.43 - 5.05），以及处于BMI-WC综合结果的最高类别（OR 3.28，95%置信区间：1.59 - 6.77）。在男性中未观察到相关关联。
超加工食品重量比例与女性超重呈强剂量依赖性关联，但与男性无关。需要进一步研究以阐明这种关联背后的潜在机制。越来越多的证据表明超加工食品消费对健康有有害影响，这凸显了在未来公共卫生策略中考虑这些产品的必要性。
