To determine the joint association of junk food consumption (JFC) and screen time (ST) with adiposity in children.
Two hundred fourteen (121 girls, 93 boys) third-to-fifth-grade students (54% Hispanic, 35% African American, 8% white) completed a lifestyle behavior survey, which included self-reported JFC and ST, as part of a school-based lifestyle intervention program.
Neither JFC nor ST, independently or jointly, was associated with adiposity measures. JFC and ST were significantly correlated (r = .375).
The low achievement of physical activity and screen time recommendations and high prevalence of overweight/obesity in this mostly minority, low socioeconomic status population indicates a potential focus for intervention.
确定儿童垃圾食品消费（JFC）和屏幕使用时间（ST）与肥胖的联合关联。
作为一项基于学校的生活方式干预项目的一部分，214名三至五年级学生（121名女生，93名男生）（54%为西班牙裔，35%为非裔美国人，8%为白人）完成了一项生活方式行为调查，其中包括自我报告的垃圾食品消费和屏幕使用时间。
无论是垃圾食品消费还是屏幕使用时间，单独或联合起来，均与肥胖指标无关。垃圾食品消费和屏幕使用时间显著相关（r = 0.375）。
在这个以少数族裔为主、社会经济地位较低的人群中，体育活动和屏幕使用时间建议的达标率较低，超重/肥胖的患病率较高，这表明有必要进行干预。
