To explore the associations between changes in weight, eating disorder psychopathology and psychological distress in a community sample of women with eating disorders over two years.
One hundred and twenty two women identified with disordered eating in a baseline population survey agreed to participate in a follow-up study, of whom 87 (71%), mean age 28+/-6.2, completed the two-year follow-up. Body mass index, eating disorder psychopathology, psychological distress, and demographic details were assessed at both time points.
Over the two years there was a mean weight gain of 1.76 kg (SD=7.03), 11 (13%) women lost > or =5 kg, 25 (29%) gained > or =5 kg, and 49 (58%) remained weight stable (i.e., within 5 kg of baseline weight). Comparisons between those who had lost, gained and remained weight stable showed few significant differences, however, women who remained weight stable were the least psychologically distressed at baseline and those who lost weight had the greatest reduction in shape concern. Body mass index at baseline, and change in level of binge eating episodes were not associated with weight change.
Disordered eating behaviours have little influence on weight change over two years in community women with disordered eating. Low levels of psychological distress at baseline may promote weight stability. Concerns about shape are likely to increase with increased weight.
探讨在两年时间里，社区中患有饮食失调症的女性样本的体重变化、饮食失调心理病理学与心理困扰之间的关联。
在一项基线人口调查中，122名被确定有饮食失调问题的女性同意参与一项随访研究，其中87名（71%）完成了两年随访，平均年龄为28±6.2岁。在两个时间点均对体重指数、饮食失调心理病理学、心理困扰及人口统计学细节进行了评估。
在这两年间，平均体重增加了1.76千克（标准差=7.03），11名（13%）女性体重减轻≥5千克，25名（29%）女性体重增加≥5千克，49名（58%）女性体重保持稳定（即与基线体重相差在5千克以内）。体重减轻、增加及保持稳定的女性之间的比较显示，差异不显著，然而，体重保持稳定的女性在基线时心理困扰最小，而体重减轻的女性对体型的关注减少最多。基线时的体重指数以及暴饮暴食发作次数的变化与体重变化无关。
饮食失调行为对社区中患有饮食失调症的女性在两年内的体重变化影响不大。基线时较低水平的心理困扰可能有助于体重稳定。对体型的关注可能会随着体重增加而增加。
