AB  - Sleep disorders are linked to obesity, type 2 diabetes mellitus (T2DM) and 
      cardiovascular disease (CVD). The evidence suggests that dietary carbohydrate 
      content may be related to sleep duration. We designed a study to investigate the 
      association between a low-carbohydrate diet (LCD) with long sleep duration 
      (> 8 h) and short sleep duration (< 5 h). This cross-sectional analysis was 
      conducted on data obtained from the recruitment phase of Yazd Health Study (YaHS) 
      and the Taghzieh Mardom-e-YaZd (TAMYZ). The dietary intake was assessed using a 
      validated food frequency questionnaire. The LCD score was calculated for each 
      subject based on summing up assigned scores to deciles of percentages of energy 
      from macronutrients. Sleep duration was assessed using a nocturnal sleep 
      questionnaire. The association between LCD and sleep duration was evaluated using 
      logistic regressions in crude and adjusted models. A total of 5929 subjects were 
      entered into the analysis. Most of the participants were aged 20-29 years 
      (24.8%), male (52.2%) and never smokers (87.7%). After adjusting for level of 
      physical activity, age, sex, total energy, smoking status and body mass index in 
      model III, a significant direct association was observed between LCD score with 
      long sleep duration (OR 1.15; 95% CI1-1.32, P = 0.049) and short sleep duration 
      (OR 1.29; 95% CI 1.02-1.62, P = 0.028). Higher LCD score is associated with 
      higher chance of long sleep duration and short sleep duration. Regarding the 
      nature of our study, cohort and clinical trial studies in future are required to 
      reach a causal association and a definitive conclusion.
