Design: Prospective longitudinal study.
Setting: Not applicable.
Patient(s): A total of 1,544 girls, aged 7-15 years in 1985, and who completed questionnaires at follow-up in 2004-2006 and/or 2009-2011.
Main outcome measure(s): Infertility was defined as having difficulty conceiving (had tried for ≥12 months to become pregnant without succeeding) or having seen a doctor because of trouble becoming pregnant.
Result(s): At ages from 7-11 years, girls at both the lower and upper end of the body mass index (BMI) z score had increased risk of infertility. Compared with normal weight girls, those with obesity at ages 7-11 years were more likely in adulthood to report infertility (adjusted relative risk [aRR] = 2.94, 95% confidence interval [CI] 1.48-5.84), difficulty conceiving (aRR = 3.89, 95% CI 1.95-7.77), or having seen a doctor because of trouble becoming pregnant (aRR = 3.65, 95% CI 1.90-7.02) after adjusting for childhood age, follow-up length, highest parental education, and marital status.
Conclusion(s): Childhood obesity before 12 years of age appears to increase the risk of female infertility in later life.
