Understanding the impact of commercial weight management programmes on behaviour change is an area that requires greater evidence. The present study investigated the impact of a commercial weight management organisation's diet and activity programmes on the lifestyles of those accessing the services and their families.
This survey was based on self-reports from a group of people involved in their own weight control. A questionnaire consisting of multiple choice and open-ended questions regarding diet, activity patterns and health was distributed in a commercial slimming organisation's magazine and was available on the website for a 4 week period. Two thousand eight hundred and twelve respondents were analysed, including the organisation's members (53%) and nonmembers (47%).
Those following the dietary programme reported significant changes towards healthier food choices in line with current guidelines (P < 0.01). Over 80% reported an improvement in their own health and over 26% reported an improvement in their partner's or family's health (P < 0.01). Respondents reported increasing physical activity after being made aware of the organisation's activity programme (P < 0.001). Members were more likely to have become more active than nonmembers (P = 0.011). The longer respondents had been members, the more likely they were to report an increased participation in physical activity (P = 0.02). Half of those reporting increased activity indicated that their partner or whole family had also increased their activity levels.
The commercial slimming organisation's programme appeared to be having a beneficial impact on the diet and activity behaviours of those accessing the service. Group members were more likely to make positive behaviour changes and health improvements tended to increase with the duration of membership. The improvements observed with respect to both diet and activity levels also reached the wider family network.
了解商业体重管理计划对行为改变的影响是一个需要更多证据的领域。本研究调查了一家商业体重管理机构的饮食和活动计划对使用该服务的人员及其家人生活方式的影响。
本调查基于一组参与自身体重控制的人员的自我报告。一份包含有关饮食、活动模式和健康的多项选择题和开放式问题的问卷在一家商业减肥机构的杂志上分发，并在网站上提供了4周时间。对2812名受访者进行了分析，包括该机构的成员（53%）和非成员（47%）。
遵循饮食计划的人员报告称，根据当前指南，他们在选择更健康食物方面有显著变化（P < 0.01）。超过80%的人报告自身健康有所改善，超过26%的人报告其伴侣或家人的健康有所改善（P < 0.01）。受访者报告称，在了解该机构的活动计划后，他们增加了体育活动（P < 0.001）。成员比非成员更有可能变得更加活跃（P = 0.011）。受访者成为成员的时间越长，他们报告增加体育活动参与度的可能性就越大（P = 0.02）。报告活动增加的人中，有一半表示他们的伴侣或整个家庭的活动水平也有所提高。
该商业减肥机构的计划似乎对使用该服务的人员的饮食和活动行为产生了有益影响。团体成员更有可能做出积极的行为改变，并且健康改善往往随着会员期限的延长而增加。在饮食和活动水平方面观察到的改善也延伸到了更广泛的家庭网络。
