Abstract

The objective of this study was to compare the relations among nutrient intake, fitness, serum antioxidants, and cardiolipoprotein profiles in female adolescents. The study design was a cross-sectional analysis of the Penn State Young Women's Health Study. The present study was performed with the entire cohort (n = 86) when they were 17.1 ± 0.5 y (x̄ ± SD) of age. Primary measurements included cardiolipoprotein indexes, serum antioxidants, nutrient intakes, aerobic fitness, and percentage body fat. The cohort was stratified by estimated maximal oxygen uptake (V̇O2max) measurements and by percentage body fat. The fifth quintile by estimated V̇O2max had significantly lower percentage body fat, higher athletic scores, higher fruit intake, lower total serum cholesterol, and lower ratios of total serum cholesterol to HDL cholesterol than members of the first quintile. When the members of the first and fifth quintiles by percentage body fat were compared, the first quintile had significantly lower weight, lower body mass index, higher estimated V̇O2max, higher athletic scores, lower ratios of total serum cholesterol to HDL cholesterol, and higher fruit, carbohydrate, and fiber intakes. Correlation analyses performed with the data for the entire cohort showed fruit consumption to be positively correlated with estimated V̇O2max, and predicted V̇O2max to be positively correlated with circulating β-carotene and α-tocopherol. This study provided evidence that the positive associations of exercise and fruit consumption with cardiovascular health apply to female adolescents as well as to adults.
