After recovery, women with anorexia nervosa (AN) tend to maintain lower body mass indices (BMI) than women in the general population. Reasons for this are unknown as little is known about diet, food choices, physical activity levels (PAL), and reasons for exercise in women recovered from AN.
Diet, reasons for food choice, PAL, and reasons for exercise were measured in an exploratory study of 15 women recovered from AN and 22 women with no eating disorder history.
In these hypotheses generating analyses, mean BMI in recovered women was numerically lower than control women [21.4 kg/m(2) (2.0) and 23.6 kg/m(2) (4.4); respectively (p < .06)]. Recovered women were more likely to base food choice on health benefits (p < .04) compared with control women.
Pathological behaviors that are pathognomonic of AN may resolve into healthy food and activity choices that help maintain BMIs lower in the healthy range in recovered individuals.
神经性厌食症(AN)女性在康复后往往比一般人群保持更低的身体质量指数(BMI)。造成这种情况的原因尚不清楚,因为人们对饮食、食物选择、身体活动水平(PAL)以及 AN 康复女性锻炼的原因知之甚少。
在一项对 15 名 AN 康复女性和 22 名无饮食失调史的女性的探索性研究中,测量了饮食、食物选择的原因、PAL 和运动的原因。
在这些假设生成分析中,康复女性的平均 BMI 数值低于对照组女性[21.4 kg/m(2)(2.0)和 23.6 kg/m(2)(4.4);分别(p <.06)]。与对照组女性相比,康复女性更倾向于基于健康益处选择食物(p <.04)。
AN 特有的病理行为可能转化为健康的食物和活动选择,帮助康复个体保持 BMI 在健康范围内较低的水平。
