Resumen
- The purpose of this study was to investigate the prevalence of normal weight obesity (NWO) and evaluate the relationship between NWO and health risk factors in a collegiate dancer population. Reanalysis of data of female dancers (N = 42) from 2 larger studies was used to assess prevalence and health risk factors of NWO. Dancers completed a dual-energy x-ray absorptiometry scan to assess fat mass (FM), lean mass (LM), and visceral adipose tissue (VAT) and a 3-day food record. Normal weight obesity was defined as a body mass index (BMI) of 18.5-24.9 kg[middle dot]m-2 and body fat (BF) >=30%. Twenty-five (60%) dancers were classified as normal weight lean (NWL), and 17 dancers (40%) were classified as NWO. Significant differences were observed for BMI (NWL: 21.1 +/- 1.7, NWO: 23.1 +/- 1.6, p < 0.001), LM (NWL: 71.0 +/- 2.9%, NWO: 62.5 +/- 2.7%, p < 0.001), %BF (NWL: 24.8 +/- 3.1%, NWO: 33.9 +/- 2.6%, p < 0.001), and VAT (NWL: 130.6 +/- 43.0 g, NWO: 232.3 +/- 70.8 g, p < 0.001) between NWL and NWO. A significant difference was observed for carbohydrate intake (NWL: 4.7 +/- 1.8 g[middle dot]kg-1, NWO: 3.7 +/- 1.0 g[middle dot]kg-1, p = 0.020) between groups. Significant positive correlations with FM were observed between carbohydrate (kcal, p = 0.048), fat (kcal, p = 0.018; g[middle dot]kg-1, p = 0.040), and total calories (p = 0.019) in NWO. Normal weight obesity in collegiate dancers may be more prevalent than previously perceived and may be significantly related to important health risk factors. The current study demonstrates the need for body composition assessments and emphasizing on promoting overall health in collegiate dancers.
