Effect of Physical Activity and Obesity on Type 2 Diabetes in a Middle-Aged Population

Abstract EN

Background.

The physical activity has been associated with a reduced risk of type 2 diabetes.

The aim of this study was to examine the effect of physical activities such as occupational, household and daily lifestyle activities and obesity on the prevalence of type 2 diabetes in middle-aged population.

Methods.

All people (n = 2053), aged 45–64 years were selected for this study from the large sample of population-based cross-sectional data collected in the 1990–1994 by National Health Survey of Pakistan.

The participants completed in-person interviews at baseline; the overall response rate was 92.6%.

The Cox proportional hazards model was used to estimate the risk of developing the type 2 diabetes.

Results.

Stair climbing was found to be inversely associated with the risk of diabetes and cycling was also associated with a reduced risk of type 2 diabetes (RR=0.82; 95% CI 0.68–1.00, P=.048).

The relationship between physical activity and reduced risk of diabetes adjusted for age and body mass index was statistically significant only in women (P<.01).

Conclusions.

This study provides an incentive that physical activity in leisure-time exercise or daily activity reduces the risk of type 2 diabetes in a high-risk population.
