Abstract

Background: This cross-sectional comparative study examined differences in body mass index (BMI), nutritional knowledge, and eating behaviors between dancer and non-dancer university students. Given the physical and aesthetic demands of dance, understanding potential differences in health-related characteristics in this population is of particular importance.

Methods: Seventy female undergraduates (35 dancers and 35 non-dancers, aged 17-22 years) were recruited. Height, weight, and BMI were measured using the InBody 970 analyzer. Nutritional knowledge was assessed using the Chinese version of the General Nutrition Knowledge Questionnaire (C-GNKQ), and disordered eating risk was evaluated using the Eating Attitudes Test-26 (EAT-26)©. Group differences were analyzed using independent t-tests, with effect sizes (Cohen's d) calculated to estimate the magnitude of differences.

Results: Dancers were significantly taller than non-dancers (P = 0.003, d = 0.74) and had a lower BMI (P = 0.023, d = 0.82). No statistically significant difference was observed in overall C-GNKQ scores (P = 0.128, d = 0.37), although dancers scored higher in the dietary knowledge subscale (P = 0.037, d = 0.52). EAT-26© scores were higher in dancers, but the difference was not statistically significant (P = 0.147, d = 0.35). Additional Spearman correlation analyses revealed no significant associations among BMI, C-GNKQ scores, and EAT-26© scores (P > 0.05).

舞蹈学生和非舞蹈学生的体重指数、营养知识和饮食态度。

背景：本横断面比较研究考察了舞蹈和非舞蹈大学生在身体质量指数（BMI）、营养知识和饮食行为方面的差异。鉴于舞蹈对身体和审美的要求，了解这一人群健康相关特征的潜在差异尤为重要。方法：招募70名女大学生（舞蹈演员35名，非舞蹈演员35名，年龄17-22岁）。使用InBody 970分析仪测量身高、体重和BMI。采用中文版普通营养知识问卷（C-GNKQ）评估营养知识，采用饮食态度测试-26 （EAT-26）©评估饮食失调风险。使用独立t检验分析组间差异，计算效应量（Cohen’s d）来估计差异的大小。结果：跳舞者明显高于非舞蹈者（P = 0.003, d = 0.74）， BMI低于非舞蹈者（P = 0.023, d = 0.82）。总体C-GNKQ得分差异无统计学意义（P = 0.128, d = 0.37），尽管舞蹈演员在饮食知识亚量表上得分较高（P = 0.037, d = 0.52）。舞蹈演员的EAT-26©得分较高，但差异无统计学意义（P = 0.147, d = 0.35）。进一步的Spearman相关分析显示，BMI、C-GNKQ评分和EAT-26©评分之间无显著相关性（P < 0.05）。
