The rise in online-to-offline (O2O) take-out food consumption has become a global urban phenomenon. While links between general fast-food consumption and increased risks of overweight and obesity are well-documented, the specific relationship with O2O take-out food has not been thoroughly examined. This study aims to fill this research gap by investigating the impacts of take-out food consumption on the risks of being overweight and obese among urban residents. A cross-sectional online survey was conducted between April and July 2022. 716 adult respondents from the metropolitan areas of Shanghai and Suzhou were recruited. Being overweight and obese were measured using self-reported weight and height. Frequencies and preferences of O2O take-out food consumption behaviors were measured using the validated questions designed based on Food Frequency Questionnaires and Dietary Screeners, respectively. The International Physical Activity Questionnaire's short form measured the physical activity level. Cronbach's alpha and Expletory Factor Analysis were used to assess the reliability and validity of the O2O take-out food-related dietary questions. Binary logistic regression models are developed to examine associations between O2O take-out food consumption behaviors and being overweight or obese, adjusting for individual factors, physical activity level, and non-O2O take-out food consumption. The results indicated a direct correlation between frequent O2O take-out consumption and higher risks of overweight and obesity (odds ratio 1.087, 95%CI 1.0681.106). The preference for ordering Western-style fast-food positively contributed to being overweight and obese (odds ratio 1.071, 95%CI 1.0461.095). Conversely, a preference for Chinese-style fast food initially appeared to reduce these risks, although the association diminished when accounting for fruit and vegetable consumption. This study represents a pioneering exploration into the effects of O2O take-out food on overweight and obesity. The study results identified an association between the habitual use of O2O take-outs and an increased propensity for being overweight and obese.
线上到线下（O2O）外卖食品消费的增加已成为一种全球城市现象。虽然一般快餐消费与超重和肥胖风险增加之间的联系已有充分记录，但与O2O外卖食品的具体关系尚未得到充分研究。本研究旨在通过调查外卖食品消费对城市居民超重和肥胖风险的影响来填补这一研究空白。2022年4月至7月进行了一项横断面在线调查。招募了来自上海和苏州大都市地区的716名成年受访者。超重和肥胖通过自我报告的体重和身高来衡量。O2O外卖食品消费行为的频率和偏好分别使用基于食物频率问卷和饮食筛查工具设计的有效问题来衡量。国际体力活动问卷简表测量身体活动水平。使用克朗巴哈系数和探索性因子分析来评估与O2O外卖食品相关的饮食问题的信度和效度。建立二元逻辑回归模型以检验O2O外卖食品消费行为与超重或肥胖之间的关联，并对个体因素、身体活动水平和非O2O外卖食品消费进行调整。结果表明，频繁的O2O外卖消费与超重和肥胖风险较高直接相关（优势比1.087，95%置信区间1.0681.106）。订购西式快餐的偏好对超重和肥胖有正向影响（优势比1.071，95%置信区间1.0461.095）。相反，对中式快餐的偏好最初似乎会降低这些风险，尽管在考虑水果和蔬菜消费后这种关联减弱。本研究是对O2O外卖食品对超重和肥胖影响的开创性探索。研究结果确定了经常使用O2O外卖与超重和肥胖倾向增加之间的关联。
