STUDY OBJECTIVE: To examine the relationship between dietary intake and @entity1017 among adolescent females initiating depot @entity11796 (DMPA). DESIGN: Prospective observational study. SETTING: Two urban Adolescent Medicine clinics. @entity1 : 45 postmenarchal females, age 12 to 21, enrolled after self-selecting to initiate DMPA. INTERVENTION: @entity1 received 150  mg DMPA intramuscularly every 12  weeks. Height, weight, and 24-hour dietary recall were collected at baseline, 3, 6, and 12  months. MAIN OUTCOME MEASURE: Body mass index (BMI) over time calculated as weight (kg)/height (m(2)). Associations between dietary variables and BMI were evaluated with repeated measures analysis of variance modeling. RESULTS: Mean chronological and gynecologic ages were 16.2      1.5 and 4.2      1.8  years, respectively. Mean BMI increased from 23.7      5.3 to 25.3      5.7 over 12  months. Average dietary intake included: 1781.4      554.1 total kilocalories, 228.5  g      69.8 @entity3363 , 71.0  g      27.3 fat, and 61.0  g      20.2 protein. These diet measures were not associated with BMI over time. Dietary fiber, @entity1760 , and @entity4722 were inversely associated with increased BMI over time (P  <  .05) CONCLUSION: We found no evidence that general measures of diet (energy, @entity3363 , fat, and protein), as assessed by 24-hour recall, were predictive of @entity1017 on DMPA. Several nutrients abundant in foods that benefit overall health were inversely associated with increased BMI over time, suggesting that diet quality, rather than quantity, is a more important predictor of DMPA-associated @entity1017 .
