We examined associations between fast-food intake and perceived and objective fast-food outlet exposure.
Information from the Health Behaviours in School-aged Children Study was linked to fast-food outlets in seventy-five school neighbourhoods. We used multivariate multilevel logistic regression analyses to examine associations between at least weekly fast-food intake and perceived and objective fast-food outlet measures.
Data represent 4642 adolescents (aged 11-15 years) in Denmark.
Boys reporting two or more fast-food outlets had 34% higher odds consuming fast food at least weekly. We detected higher odds of at least weekly fast-food intake among 15-year-old 9th graders (ORall=1.74; 95% CI 1.40, 2.18; ORboys=2.20; 95% CI 1.66, 2.91; ORgirls=1.41; 95% CI 1.03, 1.92), Danish speakers (ORall=2.32; 95% CI 1.68, 3.19; ORboys=2.58; 95% CI 1.69, 3.93; ORgirls=2.37; 95% CI 1.46, 3.84) and those travelling 15 min or less to school (ORall=1.21; 95% CI 1.00, 1.46; ORgirls=1.44; 95% CI 1.08, 1.93) compared with 11-year-old 5th graders, non-Danish speakers and those with longer travel times. Boys from middle- (OR=1.28; 95% CI 1.00, 1.65) and girls from low-income families (OR=1.46; 95% CI 1.05, 2.04) had higher odds of at least weekly fast-food intake compared with those from high-income backgrounds. Girls attending schools with canteens (OR=1.47; 95% CI 1.00, 2.15) had higher odds of at least weekly fast-food intake than girls at schools without canteens.
The present study demonstrates that perceived food outlets may impact fast-food intake in boys while proximity impacts intake in girls. Public health planning could target food environments that emphasize a better understanding of how adolescents use local resources.
我们研究了快餐摄入量与感知到的和客观存在的快餐店暴露之间的关联。
来自学龄儿童健康行为研究的信息与75个学校周边地区的快餐店相关联。我们使用多变量多层次逻辑回归分析来研究至少每周食用一次快餐与感知到的和客观存在的快餐店指标之间的关联。
数据代表丹麦的4642名青少年（年龄在11至15岁之间）。
报告称周边有两家或更多家快餐店的男孩每周至少食用一次快餐的几率高34%。我们发现，与11岁的五年级学生、非丹麦语使用者以及上学途中时间较长的学生相比，15岁的九年级学生（总体比值比=1.74；95%置信区间1.40, 2.18；男孩比值比=2.20；95%置信区间1.66, 2.91；女孩比值比=1.41；95%置信区间1.03, 1.92）、说丹麦语的学生（总体比值比=2.32；95%置信区间1.68, 3.19；男孩比值比=2.58；95%置信区间1.69, 3.93；女孩比值比=2.37；95%置信区间1.46, 3.84）以及上学途中时间为15分钟或更短的学生（总体比值比=1.21；95%置信区间1.00, 1.46；女孩比值比=1.44；95%置信区间1.08, 1.93）每周至少食用一次快餐的几率更高。与来自高收入家庭背景的学生相比，来自中等收入家庭的男孩（比值比=1.28；95%置信区间1.00, 1.65）和来自低收入家庭的女孩（比值比=1.46；95%置信区间1.05, 2.04）每周至少食用一次快餐的几率更高。与没有食堂的学校的女孩相比，就读于有食堂学校的女孩（比值比=1.47；95%置信区间1.00, 2.15）每周至少食用一次快餐的几率更高。
本研究表明，感知到的食品店可能会影响男孩的快餐摄入量，而距离则会影响女孩的摄入量。公共卫生规划可以针对那些能更好理解青少年如何利用当地资源的食品环境。
