Increased leisure-time physical activity associated with lower onset of diabetes in adults.

A new study published in the British Journal of Sports Medicine evaluated the effects of habitual leisure-time physical activity (LTPA) on incident type-2 diabetes in adults with impaired fasting glucose (IFG). This study enrolled a prospective cohort of 44,828 Chinese adults aged 20-80 years with newly detected IFG who were free from cardiovascular and cerebrovascular disease; these patients were followed-up from 1996 to 2014. The participants were classified into four categories based on their self-reported weekly leisure-time physical activity (LTPA): inactive, low, moderate or high. The results revealed an inverse dose-response relationship between LTPA and diabetes risk. When compared to inactive participants, diabetes risk in individuals reporting low, moderate and high volume LTPA were reduced by 12%, 20%, and 25%, respectively. It was estimated that a minimum of 19.2% of incident diabetes cases could be avoided if the inactive participants had engaged in WHO recommendation levels of LTPA. The findings suggested that higher levels of LTPA is associated with a lower risk of diabetes in IFG subjects. It was stated that these findings highlight the urgent need for promoting physical activity as a preventive strategy against diabetes.
