[Related factors for early-onset type 2 diabetes mellitus of rural adults in Yuhuan County of Zhejiang Province in 2012].

OBJECTIVE

To explore related factors for early-onset type 2 diabetes mellitus( EOD) in rural Chinese adults.

METHODS

Totally, 1695 newly diagnosed cases of type 2 diabetes mellitus( T2DM) were recruited from baseline survey of Yuhuan Rural Adults Cohort for Diabetes during June to December 2012 in Yuhuan County, Zhejiang Province, China, and divided into EOD or late-onset type 2 diabetes mellitus( LOD) with their diagnosis age at ≤ 40 or > 40 years, respectively. Diagnosis age was compared among different characteristics. Logistic regression was used to analyze related factors in EOD.

RESULTS

Among 1695 new T2 DM cases, near half( 47. 3%) were men and 85( 5. 0%) were grouped into EOD. Their mean age at diagnosis of T2 DM was( 60. 39 ±12. 49) years overall. Men or those with more than 9 education years, family average personal income ≥2000 Yuan per month, less occupational physical activities, smoking, drinking, overweight and family history of T2 DM had lower average age at diagnosis than women or those without them, while those with regular physical exercise had higher that than those without that. After the adjustment for other covariates, multiple logistic regression showed that more than 9 education years( OR = 6. 62, 95% CI 3. 87-11. 32), family average personal income ≥2000 Yuan per month( OR = 6. 60, 95% CI 3. 32-13. 12), and regular physical exercise( OR = 0. 37, 95% CI 0. 17-0. 80) were independently correlated to EOD.

CONCLUSION

Education level, income, and regular exercise are significantly correlated to EOD in rural Chinese adults.
