Television viewing and pedometer-determined physical activity among multiethnic residents of low-income housing

Objectives. We evaluated the association between television viewing and pedometer-determined physical activity among predominantly racial/ethnic minority residents of low-income housing in metropolitan Boston in 2005. Methods. We used mixed models to analyze the association between reported hours of television viewing and pedometer-determined steps per day among 486 adults. We also examined whether television viewing was associated with the achievement of 10000 steps per day. Results. There was a mean 3.6 hours of average daily television watching. In multivariable analyses, each hour of television viewing on an average day was associated with 144 (95% confidence interval [CI] =-276, -12) fewer steps per day and a decreased likelihood of accumulating 10000 steps per day (odds ratio [OR] = 0.84; 95% Cl = 0.71, 0.99). Weekday and weekend television viewing were each also associated with fewer steps per day. Conclusions. Average daily television viewing was associated with reductions in total pedometer-determined physical activity levels (approximately 520 steps per day) in this lower-income sample. As part of a comprehensive physical activity promotion plan, recommendations to reduce television viewing should be made.
