The detection  rate of obesity of the  rural adults  in Jilin Province was higher than the mean level in China . For rural adults with moderate and adequate diversity score,the risk of overweight and obesity was  0.946 and 0.816 times the risk of overweight and obesity of the rural adults with pool diversity score.
