The participants' subjective health perceptions were analyzed according to their sleep habits. Results: Weekday and weekend sleep durations were related to subjective health in older men (p<0.05) but not in women. The subjective health perception was significantly better for a 9-hour sleep duration than for a 7-hour sleep duration in older men. Sleeping and waking times on weekdays and weekends were not related to the subjective health of either men or women. Conclusion: Weekday and weekend sleep durations were related to subjective health perception in older men.
