This study investigated the frequency of risk behaviors for eating disorders and their association with anthropometric, demographic, and socioeconomic variables in Brazilian professional dancers. Portuguese-language versions of the Eating Attitudes Test and of the Bulimic Investigatory Test, Edinburgh (BITE) were applied to 39 female and 22 male dancers considered to be some of the best classical ballet performers in Brazil. Prevalence ratios (PR) and 95% confidence intervals (CI) were estimated. Risk behaviors for eating disorders were observed in 31% of the dancers. Those who had a percentage of body fat above (PR=4.04; 95% CI=1.42-11.47) or below (PR=3.57; 95% CI=1.04-12.24) what is considered normal for the profession, and those who lived alone (PR=3.13; 95% CI=1.16-8.48) presented higher risk for eating disorders. In conclusion, the frequency of risk behaviors for eating disorders among the Brazilian dancers was high, which seems to be associated with the physical requirements of the profession. Those who are outside the BF% expected for dancers and those who live alone are the groups most vulnerable to developing eating disorders, and thus are the ones which are most in need of receiving special attention in regard to the intervention measures.
本研究调查了巴西职业舞者饮食障碍风险行为的发生频率及其与人体测量学、人口统计学和社会经济学变量的相关性。研究采用了葡萄牙语版的 Eating Attitudes Test(EAT)和 Bulimic Investigatory Test, Edinburgh(BITE)对 39 名女性和 22 名男性舞者进行了评估,这些舞者被认为是巴西最优秀的古典芭蕾演员之一。研究估计了患病率比(PR)及其 95%置信区间(CI)。研究发现,31%的舞者存在饮食障碍风险行为。那些体脂百分比高于(PR=4.04;95%CI=1.42-11.47)或低于(PR=3.57;95%CI=1.04-12.24)该职业正常范围的舞者,以及那些独居的舞者(PR=3.13;95%CI=1.16-8.48),其饮食障碍风险更高。总之,巴西舞者中存在较高频率的饮食障碍风险行为,这似乎与该职业的身体要求有关。那些体脂百分比不在预期范围内的舞者和独居的舞者是最容易患上饮食障碍的群体,因此,他们是最需要接受特殊关注和干预措施的群体。
