The Impact of Daily Sleep Hours on the Health of Korean Middle-Aged Women

This study aimed to examine the association between sleep and health in order to provide useful information to manage the health of obese women in the future. One hundred fifty-five Korean women aged 40–60 years without a previous diagnosis of abnormal glucose metabolism or other health problems and with body fat percentages greater than 30 percent were classified into two groups: a non-obese group and an obese group. Sleep hours exhibited a significant positive correlation with weight, body mass index, muscle mass, and glucose levels in the obese group. Significant differences were found for the body composition except the muscle mass. For physical fitness, all factors were significantly different between two groups. Additionally, there were correlations between sleep hours and weight, body mass index, muscle mass, and glucose level in the obese group. However, sleep hours did not exhibit these correlations in the non-obese group.
