Obesity rates have risen sharply in the United States, with minority women among those most affected. Although a majority of Americans are considered inactive, little attention has been devoted to studying the correlation of sedentary behavior with dietary cravings in adults.
The current study used objective and self-report methods to measure sedentary behavior and its relationship to food cravings in a sample of overweight African American and Caucasian women.
Thirty-nine adult women (54% African American) with an average body mass index of 33.7 wore accelerometers for one week and completed self-report measures of sedentary behavior, physical activity, and food cravings.
Self-reported television viewing time was slightly longer (3.0 versus 2.5 hours), although total sedentary time was shorter (6.7 versus 8.0 hours) on weekends versus weekdays. Weekend but not weekday sedentary time and television viewing were associated with stable aspects of food cravings rather than craving for specific foods.
In this small sample, only a third of all sedentary time was attributed to viewing television. Assessing whether sedentary behavior occurs by necessity versus choice may be a factor to consider in examining its relationship to food cravings.
美国的肥胖率急剧上升,少数族裔女性受影响最为严重。尽管大多数美国人被认为缺乏运动,但对于成年人久坐行为与饮食渴望之间的相关性研究却很少。
本研究采用客观和自我报告的方法,测量超重非裔美国人和白人女性样本中的久坐行为及其与食物渴望的关系。
39名成年女性(54%为非裔美国人),平均体重指数为33.7,佩戴加速度计一周,并完成关于久坐行为、身体活动和食物渴望的自我报告测量。
自我报告的看电视时间略长(周末为3.0小时,工作日为2.5小时),尽管周末的总久坐时间比工作日短(分别为6.7小时和8.0小时)。周末而非工作日的久坐时间和看电视与食物渴望的稳定方面相关,而非对特定食物的渴望。
在这个小样本中,所有久坐时间中只有三分之一归因于看电视。评估久坐行为是出于必要还是选择,可能是在研究其与食物渴望的关系时需要考虑的一个因素。
