To examine behavioural characteristics of subjects with successful long-term weight reduction.
Prospective cohort study with 3 y follow-up.
Multicentre study of participants of a commercial weight-reduction programme (BCM-Programme).
Until February 2000, 6857 voluntary study participants were included. Analyses are based on 1247 subjects with complete 3 y data.
Open-group dietary and behavioural counselling with initial meal substitutions.
Subjects show a number of significant behavioural improvements, for example, choice of low-fat food, flexible control of eating behaviour and coping with stress. Subjects who maintain these changes by the end of the first year have a higher probability of successful weight reduction after 3 y.
Successful weight maintenance is associated with more pronounced improvements of health behaviours after 1 y. The likelihood of success increases with the number of behavioural patterns which are involved in the process of change.
研究长期成功减重受试者的行为特征。
为期3年随访的前瞻性队列研究。
一项商业减重计划（BCM计划）参与者的多中心研究。
截至2000年2月，纳入6857名自愿参与研究的受试者。分析基于1247名有完整3年数据的受试者。
开放式小组饮食和行为咨询，并进行初始餐食替代。
受试者出现了一些显著的行为改善，例如选择低脂食物、灵活控制饮食行为以及应对压力。在第一年末维持这些改变的受试者在3年后成功减重的概率更高。
成功维持体重与1年后更明显的健康行为改善相关。成功的可能性随着参与改变过程的行为模式数量增加而提高。
