Association of adolescent obesity and lifetime nulliparity

Association of adolescent obesity and lifetime nulliparity – SWAN, the study of women's health across the nation
Alex J Polotzky et al., 2011




To evaluate whether adolescent obesity is associated with difficulties for becoming pregnant later in life.


Cross-sectional analysis of baseline data from a longitudinal cohort


Multiethnic, community-based observational study of US women


3154 midlife women

Main Outcome Measure(s)

Lifetime nulliparity and lifetime nulligravidity


527 women (16.7%) women had never delivered a baby. Participants were categorized by self-reported high school body mass index (BMI): underweight (< 18.5 kg/m2), normal (18.5 to 24.9 kg/m2), overweight (25-29.9 kg/m2), and obese (> 30 kg/m2). The prevalence of lifetime nulliparity increased progressively across the high school BMI categories: 12.7%, 16.7%, 19.2%, and 30.9%, respectively (p<0.001). Multivariable logistic regression analysis confirmed that women who were obese adolescents had significantly higher odds of remaining childless as compared to normal weight women (odds ratio [OR] 2.84, 95% confidence intervals [CI] 1.59 to 5.10) after adjusting for adult BMI, history of non-gestational amenorrhea, marital status, ethnicity, study site, and measures of socioeconomic status. Furthermore, adolescent obesity was associated with lifetime nulligravidity (OR 3.93, 95% CI 2.12 to 7.26).


Adolescent obesity is associated with lifetime nulliparity and nulligravidity in midlife U.S. women.


[There seems to be a connection between high sugar diets and obesity. Maybe these diets also cause a lowered fertility in women.]
