Since post-pregnancy weight retention may contribute to the development of obesity, we sought to determine whether a behavioral weight loss intervention was effective in returning women to their pre-pregnancy weight.
Ninety women who had given birth in the past 3-12 months and whose weight exceeded their pre-pregnancy weight by at least 6.8 kg were randomly assigned to either: a) a six-month behavioral weight loss intervention, delivered via correspondence or b) a no-treatment control group. Assessments of body weight, physical activity and eating patterns were conducted at pre-treatment and six months (post-treatment).
During the six month treatment, subjects in the correspondence condition lost significantly more weight than control subjects (7.8 kg vs 4.9 kg, P = 0.03) and lost a greater percentage of their excess postpartum weight (79% vs 44%, P = 0.01). Furthermore, a significantly greater percentage of correspondence subjects than controls returned to their pre-pregnancy weight (33% vs 11.5%, P < 0.05). Weight loss in the correspondence group was correlated with completion of self-monitoring records (r = 0.50, P < 0.005).
A behavioral weight loss intervention, delivered via correspondence, appears to be effective in reducing women's postpartum weight retention. Future studies should examine the acceptability and the long-term impact of a correspondence postpartum weight loss intervention.
由于产后体重滞留可能会导致肥胖症的发生，我们试图确定行为减肥干预措施是否能有效帮助女性恢复到孕前体重。
90名在过去3至12个月内分娩且体重比孕前体重至少超出6.8千克的女性被随机分为两组：a）通过通信方式进行为期六个月的行为减肥干预组；b）不接受治疗的对照组。在治疗前和治疗六个月后（治疗后）对体重、身体活动和饮食模式进行评估。
在为期六个月的治疗期间，通信干预组的受试者体重减轻显著多于对照组（7.8千克对4.9千克，P = 0.03），并且产后超重体重减轻的百分比更高（79%对44%，P = 0.01）。此外，通信干预组恢复到孕前体重的受试者比例显著高于对照组（33%对11.5%，P < 0.05）。通信组的体重减轻与自我监测记录的完成情况相关（r = 0.50，P < 0.005）。
通过通信方式进行的行为减肥干预似乎能有效减少女性产后体重滞留。未来的研究应考察通信产后减肥干预的可接受性和长期影响。
