Abstract

This longitudinal observational study determined the effect of oral contraceptive (OC) use during adolescence on peak bone mass (PBM). The sample comprised 62 non-Hispanic, White females in The Penn State Young Women's Health Study, who were studied for 8 years between the ages of 12 and 20. There were 28 OC users who used OCs for a minimum of 6 months and were still using them at age 20, and 34 nonusers who had never used the regimen. Total body bone, dedicated hipbone, and body composition measurements were made by dual-energy roentgenogram absorptiometry. There was no difference between OC users and nonusers in the anthropometric, body composition, or total body bone measurements. By age 20, the average duration of OC use by the user group was 22 months. At this age, the groups remained indistinguishable in anthropometric, body composition, total body, and hipbone measurements, and in age of menarche and sports exercise scores. These findings suggest that OC use by healthy, White, teenage females does not affect acquisition of PBM.
