The Effect of Infertile Women’s Lifestyle on the Number of Their Childbirth in 2 Years

Objectives: Infertility has been increasing in Korea, but few studies have examined the effect of lifestyle factors on childbirth among infertile Korean women. This study was designed to identify whether the lifestyle factors can predict the childbirth of infertile women in 2 years.Methods: We selected women aged under 40 diagnosed with infertility in 2016 and retrieved their national health examination data from Korean National Health Insurance Service. Regression analysis was conducted to investigate whether infertile women’s age, drinking, smoking, physical exercise, obesity, and sequela recorded in 2016 explained their childbirth in 2017 and 2018.Results: The results showed that age and obesity explained childbirth, respectively. In addition, the interaction of age and sequela predicted childbirth in 2 years.Conclusions: The findings suggest that the number of childbirth of infertile women can be inferred from lifestyle factors, which implies the importance of nonmedical factors in infertility.
