This study examined the association between TV viewing, fast food eating, and body mass index.
Associations between hours of TV viewing, frequency of eating at fast food restaurants, body mass index, and behaviors were assessed cross sectionally and longitudinally over 1 year in 1059 men and women.
Fast food meals and TV viewing hours were positively associated with energy intake and body mass index in women but not in men. TV viewing predicted weight gain in high-income women.
Secular increases in fast food availability and access to televised entertainment may contribute to increasing obesity rates in the United States.
本研究探讨了看电视、吃快餐与体重指数之间的关联。
对1059名男性和女性进行了为期1年的横断面和纵向评估,以分析看电视时长、在快餐店就餐频率、体重指数及行为之间的关联。
快餐饮食和看电视时长与女性的能量摄入及体重指数呈正相关,而与男性无关。看电视预示着高收入女性体重增加。
快餐供应的长期增加以及电视娱乐的普及可能导致美国肥胖率上升。
