American soft drink consumption (SDC) has increased since the 1960’s surpassing all other kinds of beverage consumption. In recent years, the scientific literature has suggested that SDC has been linked to the rising epidemic of obesity in children and adolescents. However, there is lack of information in scientific literature on the effects of SDC on body fat (BF%) in young females. The purpose of this study was to determine the association between SDC and BF% in young women, ages 16-24 years. Sixty-six females were asked to complete a 3-day food record, food frequency questionnaire, and an assessment BF% by dual-energy x-ray absorptiometry (DXA). Overall, participants consumed 29.44 ± 44.68 fl oz/day of soft drinks. There were significant positive associations between SDC and BF% (r = 0.24, p < 0.05). Due to the large standard deviation in SDC, secondary analysis compared moderate SDC (MSDC: < 32 fl oz/day) to high SDC (HSDC: ≥ 32 fl oz/day). Results suggested HSCD had significantly greater BF% than MSDC. Therefore, limiting the consumption of soft drinks is important in order to maintain a healthy BF%.
