  1. Bold numbers indicate P < 0.05.
  2. DIS: difficulty initiating sleep (30 min ≥ sleep latency); 95% CI: 95% confidence interval.
  3. Odds ratios and 95% confidence intervals were adjusted for age, gender, hypnotic use, body mass index, leisure-time physical activity and consumption of milk and milk products that were not used as independent variables.
