Objectives: Physiological changes can be the result of various health problems in postpartum women. The aim of the present study is to address the relationships among parity, sleep duration, and obesity across the lifecycle of adult Korean women.
Methods: Our study analyzed data from 10,081 participants who provided responses to the Korean National Health and Nutrition Examination Survey from 2010 to 2012. We divided the data into subgroups according to age (Group 1 [20-39 years], Group 2 [40-64 years], and Group 3 [ ≥ 65 years]), and parity (0, 1, 2, 3, and ≥ 4). We defined sleep duration as the average time spent sleeping per day. Obesity was defined as a body mass index (BMI) greater than 25.0 kg/m2 . The relationships among parity, sleep duration, and obesity were investigated using logistic and linear regression analyses.
Results: Sleep duration in women younger than 65 years decreased with increased parity (Group 1 [β]: -0.170 ± 0.050, p< 0.001; Group 2 [β]: -0.093 ± 0.027, p< 0.001). The risk of obesity increased in women aged 40 years of age and older (Group 2 [odds ratio, OR]: 1.18 [95% confidence interval: 1.09-1.28], p< 0.001; Group 3 [OR]: 1.09 (1.02-1.16), p= 0.010).
Obesity among women with parity ≥ 4 was 1.89-fold higher than that of nulliparous women in Group 2 (OR: 1.89 [1.16-3.06], p for trend < 0.001). However, sleep duration and obesity demonstrated no significant relationship in any age group.
Conclusions: Korean women were found to manifest a significant negative association between parity and sleep duration. Also, an increased risk of obesity was observed in women had more parity.
