Characteristics of Women With and Without Breast Augmentation

Abstract
Objective. —To compare selected characteristics of women with and without augmentation mammaplasty to identify differences between these 2 groups of women. Design and Study Participants. —White women identified as controls in previously conducted population-based, case-control studies formed the study population for the present cross-sectional analysis (N=3570). Main Outcome Measure. —Interview information on selected characteristics was compared between women who had received augmentation mammaplasty (n=80) and other women (n=3490) using the prevalence odds ratio (pOR) as the measure of association. Results. —Women with breast implants were more likely to drink a greater average number of alcoholic drinks per week (for >7 drinks vs 0 drinks: pOR=2.9, 95% confidence interval [Cl]=1.5-5.5), be younger at first pregnancy (for age <20 years vs age 20-29 years: pOR=1.6,95% Cl=1.0-2.7), be younger at first birth (for age 74 kg vs <56 kg: pOR=0.1, 95% Cl=0.03-0.3). Conclusion. —The differences we found between women with and without breast implants suggest that consideration and evaluation of confounding factors in future studies will help to clarify some of the long-term health consequences of having breast implants.
