Abstract
AIM
The purpose of this study was to identify psychosocial determinants for maintaining weight loss.
METHODS
42 obese individuals who achieved a 12% weight loss before entering a 52-week weight maintenance program were interviewed qualitatively. Psychosocial factors related to weight loss maintenance were identified in two contrasting groups: weight reducers and weight regainers. Groups were defined by health-relevant weight maintenance (additional weight loss > 3% at week 52, n = 9 versus weight gain > 3%, at week 52, n = 20).
RESULTS
Weight reducers reported structured meal patterns (p = 0.008), no comfort eating (p = 0.016) and less psychosocial stress (p = 0.04) compared to weight regainers. The ability to instrumentalize eating behavior emerged as an important factor (p = 0.007). Nutritional knowledge, motivation or exercise level did not differ between groups (p > 0.05).
CONCLUSIONS
Successful weight loss maintenance was associated with an interplay between behavioral, affective and contextual changes. 'Instrumentalization of eating behavior' seems to be an important element in long-term weight maintenance.
摘要
目的
本研究旨在确定维持体重减轻的心理社会决定因素。
方法
42 名在进入为期 52 周的体重维持计划前体重减轻 12%的肥胖个体接受了定性访谈。在两个对比组中确定了与体重维持相关的心理社会因素：减重者和体重恢复者。根据与健康相关的体重维持情况（第 52 周时体重额外减轻>3%，n=9 与体重增加>3%，n=20）来定义组。
结果
与体重恢复者相比，减重者报告的结构化膳食模式（p=0.008）、无安慰性进食（p=0.016）和较少的心理社会压力（p=0.04）。将进食行为工具化的能力被认为是一个重要因素（p=0.007）。营养知识、动机或运动水平在两组之间没有差异（p>0.05）。
结论
成功的体重维持与行为、情感和环境变化的相互作用有关。“进食行为的工具化”似乎是长期体重维持的一个重要因素。
