OBJECTIVE

To understand the prevalence of dyslipidemia among non-overweight adults and related factors in Zhejiang province.

METHODS

A total of 10 868 non-overweight adults (aged ≥18 years and BMI<24.0 kg/m²) included in a population-based cross-sectional survey on metabolic syndrome in Zhejiang province in 2010 were selected to conduct questionnaire survey, health examination and blood fat detection.

RESULTS

The overall prevalence of dyslipidemia in this population was 41.38%. The prevalence was significantly higher in males (43.19%) than in females (39.84%) (χ² = 12.53, P < 0.001). The prevalence of dyslipidemia significantly decreased in males (trend χ² = 47.61, P < 0.001) but increased in females (trend χ² = 3.88, P < 0.05) with age. There was no significant difference in the prevalence between urban area (41.21%) and rural area (41.49%) (χ² = 0.08, P = 0.774). Multiple logistic regression analysis showed that sex, family history of chronic diseases, smoking, alcohol use, high meat and egg diet, cooking with animal oil, physical activity, central obesity and BMI were factors related to prevalence of dyslipidemia.

CONCLUSIONS

The prevalence of dyslipidemia was high among the non-overweight adults in Zhejiang, and family history, smoking, high-fat diet, physical inactivity, central obesity seemed to be the major risk factors.
