Background: The high prevalence of online-ordered take-out food has dramatically changed Chinese urban residents' dietary behaviors in recent years, particularly among college students [1, 2]. Meanwhile, the increase in overweight and obesity has become a significant public health concern in China. However, few studies investigated the relationship between food environment, take-out consumption, and overweight and obesity nor the impacts of this emerging dietary behavior on an individual's subjective wellbeing. This study aims to fill the research gaps by quantifying the associations between neighborhood food environment, online take-out food consumption, and overweight and obesity of college students in Suzhou, China.
Methods: Suzhou, one of China's major cities in the Yangtze River Delta region, will be studied. Survey questionnaires are created based on the factors taken from the social-ecological model, theory of planned behavior, and model of community nutrition environment. Three hundred college students in Suzhou will be surveyed in March 2022 regarding their dietary behaviors of take-out food, Body Mass Index (BMI) status, Personal Wellbeing Index (PWI) level, and neighborhood food environment. Objective neighborhood food environment measures will be derived from the point of interest (POI) data of an online mapping service in China. A Structural Equation Model will be established to analyze the multivariate associations.
Anticipated results: It's hypothesized that college students who live in neighborhoods with a high density of food stores offering take-out services would have higher frequency consumption of take-out food and lower physical activity levels, resulting in overweight and obesity. Previous studies showed that western-style fast food is more likely to be high in sugar and fat [3], and it's hypothesized that the majority of the take-out food could be the same in China except for some particular exceptions.
