(HealthDay News) — Both high levels of physical activity and low levels of leisure time sitting may be necessary to reduce the risk for obesity, according to research published online in Diabetologia.
Joshua A. Bell, of University College London, and colleagues assessed the effects of moderate-to-vigorous physical activity and leisure time sitting on risk for obesity and clustering of two or more of five metabolic risk factors LDL cholesterol level, high triacylglycerol level, hypertension, hyperglycemia and insulin resistance) for 3,670 participants (male, 73%; mean age, 56 years).
The researchers found that physical activity, but not leisure time sitting, was associated with incident obesity. At 5 years of follow-up, individuals reporting both high levels of physical activity and low levels of leisure time sitting had the lowest risk fpr incident obesity (OR=0.26; 95% CI, 0.11-0.64), with weaker effects after 10 years.
At 5 years, individuals with intermediate levels of both physical activity and leisure time sitting, compared with those with low levels of physical activity and high levels of leisure time sitting, had lower risk of incident clustering of metabolic risk factors (OR=0.53; 95% CI, 0.36-0.78), with similar odds after 10 years.
“Both high levels of physical activity and low levels of leisure time sitting may be required to substantially reduce the risk of obesity,” the researchers wrote.
