AB  - BACKGROUND: The consistency and strength of the relationship between napping 
      duration and type 2 diabetes mellitus (T2DM) remained uncertain, especially in 
      the rural population. The purpose of this study was to explore the relationship 
      between napping duration and T2DM in a Chinese rural population. METHODS: A total 
      of 12663 participants (4365 males and 8298 females) were derived from the 
      RuralDiab study in China. Napping duration was obtained through a standardized 
      questionnaire, and was divided into five categories: no napping (reference), 1 approximately , 
      31 approximately , 61 approximately , and >/=91 min. Fasting blood glucose was measured. Logistic regression 
      was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). A 
      meta-analysis including seven studies was conducted to validate the result of the 
      RuralDiab study. RESULTS: The crude and age-standardized prevalence of T2DM were 
      10.31% and 8.14%, respectively. Compared with no napping, the adjusted OR (95%CI) 
      for napping duration >/=91 min was 1.23 (1.05-1.45). A similar relationship was 
      found only in females aged 45-54 years, but not in males and other age group 
      females. In addition, napping duration was associated with T2DM in a positive 
      dose-dependent manner among females aged 45-54 years (P for trend <0.05). The 
      meta-analysis demonstrated this association, and the pooled OR (95%CI) for the 
      longest napping duration compared with no napping was 1.28 (1.22-1.35). 
      CONCLUSION: Longer napping duration is associated with higher risk of T2DM in the 
      Chinese rural population, and this association varies across gender and age. 
      Further multi-center prospective researches are needed to confirm the 
      relationship and reveal underlying mechanisms.
