目的探讨快餐摄入量在就业状况、压力、抑郁、水果、蔬菜和脂肪摄入量(非裔美国人与非西班牙裔白人)和体重指数(BMI类别：超重与肥胖)之间关系的潜在中介作用。方法从密歇根州妇女、婴儿和儿童特别补充营养计划招募低收入超重和肥胖孕妇(N=332)。采用通径分析探讨种族和BMI类别对中介效应的影响。结果在非西班牙裔白人女性中，快餐摄入量在就业状况与脂肪摄入量之间起中介作用(p=0.02)，而在非裔美国女性中未发现中介作用。对于超重女性，快餐摄入量在就业状况与脂肪摄入量之间的关系(p=0.04)和抑郁症与蔬菜摄入量之间的关系(p=0.01)之间起中介作用。此外，快餐摄入量部分调节了抑郁和脂肪摄入量之间的关系(p=0.003)。对于肥胖女性，快餐摄入量在就业状况与脂肪摄入量之间起中介作用(p=0.04)。结论快餐是超重、肥胖孕妇营养教育的重要内容。如果未来的干预措施解决与就业状况(例如，缺乏时间计划和烹饪健康饮食)和抑郁情绪(例如，在应对负面情绪时无法计划饮食或购买食品)相关的问题，未来的干预措施可能会更成功。
Objective This study explored fast food intake as a potential mediator of the relationships among employment status; stress; depression; and fruit, vegetable, and fat intakes by race (African American vs. Non-Hispanic White) and body mass index (BMI category: overweight vs. obesity). Methods Low-income overweight and obese pregnant women (N = 332) were recruited from the Special Supplemental Nutrition Program for Women, Infants and Children in Michigan. Path analysis was performed to explore mediation effects by race and BMI category. Results Fast food intake mediated the relationship between employment status and fat intake (p = 0.02) in Non-Hispanic White women, but no mediation effect was detected in African American women. For overweight women, fast food intake mediated the relationship between employment status and fat intake (p = 0.04) and the relationship between depression and vegetable intake (p = 0.01). Also, fast food intake partially mediated the relationship between depression and fat intake (p = 0.003). For obese women, fast food intake mediated the relationship between employment status and fat intake (p = 0.04). Conclusion Fast food is an important topic for nutrition education for overweight and obese pregnant women. Future interventions may be more successful if they address issues associated with employment status (e.g., lack of time to plan and cook healthy meals) and depressive mood (e.g., inability to plan meals or shop for groceries when coping with negative emotions).
