摘要

粮食不安全与肥胖有关，虽然这种联系背后的机制很复杂，但粮食不安全人群闲暇时间体育活动水平较低可能是造成这种情况的原因之一。个人层面的因素（如对进行体育活动的担忧）可能在一定程度上决定了粮食不安全人群的体育活动水平，因为这些人可能会尽量减少体育活动，以保存能量。本研究使用 "食物不安全体力活动关注量表"（FIPACS）（用于测量对进行闲暇体力活动的关注，侧重于食物不安全的特定因素），调查了家庭食物不安全与体重指数（BMI）之间的关联是否可以通过 FIPACS 分数和闲暇体力活动的中介途径来解释。我们还调查了食物不安全与 FIPACS 分数之间的关联是否受营养知识的调节。参与者（N = 329，食物不安全 = 55）完成了一项在线调查，调查内容包括 FIPACS、国际体力活动问卷长式（IPAQ）、营养常识问卷的饮食、疾病和体重管理子部分、饮食质量测量以及自我报告的体重指数。研究结果显示，FIPACS 分数和闲暇时间体育活动并不能调节食物不安全与体重指数之间的关系（b < 0.01，SE = 0.01）。此外，营养知识也不能调节食物不安全与 FIPACS 分数之间的关系（b = -0.09，SE = 0.08）。研究结果表明，在食物不安全的情况下进行体育锻炼的顾虑与闲暇时间的体育锻炼无关，这两个因素不能解释食物不安全与体重指数之间的关系。未来的研究应调查食物不安全、体育活动和体重指数之间关系的其他因素。

Investigating the mediating role of physical activity within the association between food insecurity and BMI

Food insecurity is linked with obesity and while the mechanisms behind this association are complex, lower levels of leisure-time physical activity in those with food insecurity may contribute to this. Individual-level factors (such as concerns of performing physical activity) may partly determine levels of physical activity within individuals with food insecurity, as such individuals may seek to minimise their levels of physical activity in order to preserve energy. Using the Food Insecurity Physical Activity Concerns Scale (FIPACS) (used to measure concerns of performing leisure-time physical activity, focusing on factors specific to food insecurity), the current study investigated whether the association between household food insecurity and body mass index (BMI) is explained by a mediation pathway of FIPACS scores and leisure-time physical activity. We also investigated whether the association between food insecurity and FIPACS scores is moderated by nutrition knowledge. Participants (N = 329, food insecure = 55) completed an online survey consisting of the FIPACS, the International Physical Activity Questionnaire long-form (IPAQ), the Diet, Disease, and Weight management sub-section of the General Nutrition Knowledge Questionnaire, a measure of diet quality, and self-reported BMI. Findings revealed that FIPACS scores and leisure-time physical activity did not mediate the association between food insecurity and BMI (b < 0.01, SE = 0.01). Additionally, nutrition knowledge did not moderate the association between food insecurity and FIPACS scores (b = −0.09, SE = 0.08). Findings suggest that concerns of performing physical activity in the context of food insecurity are unrelated to leisure-time physical activity, and that these two factors do not explain the association between food insecurity and BMI. Future research should investigate other factors in the link between food insecurity, physical activity, and BMI.

期刊介绍： Appetite is an international research journal specializing in cultural, social, psychological, sensory and physiological influences on the selection and intake of foods and drinks. It covers normal and disordered eating and drinking and welcomes studies of both human and non-human animal behaviour toward food. Appetite publishes research reports, reviews and commentaries. Thematic special issues appear regularly. From time to time the journal carries abstracts from professional meetings. Submissions to Appetite are expected to be based primarily on observations directly related to the selection and intake of foods and drinks; papers that are primarily focused on topics such as nutrition or obesity will not be considered unless they specifically make a novel scientific contribution to the understanding of appetite in line with the journal's aims and scope.
