To test the extent to which social support and variables included in the Transtheoretical Model were explanatory for exercise initiation and weight maintenance in postpartum women.
A cross-sectional descriptive design.
Data were collected in the participant's homes.
Postpartum women who had normal pregnancies were interviewed and measured on body fat, physical activity, and psychosocial scales.
(a) Stages of exercise change measure, (b) Seven Day Recall, (c) Friend and Family Support for Exercise Scale, (d) Processes of Change Questionnaire, and (e) body fat measures including body mass index and percent body fat.
Forty percent reported engaging in vigorous activity less than 1 hour daily, 55% walked less than four city blocks daily, and 52% engaged in less than 2 hours of vigorous weekend activity. Multilinear regression showed that the processes of change contributed 36% to the body mass index, and 21% of the variance in waist-thigh ratio. Of the processes of change, environmental reevaluation correlated significantly with body mass index.
The impact of a woman's weight on others as well as information concerning the health effects of obesity and physical activity could enhance the initiation of exercise in the postpartum woman.
检验社会支持和跨理论模型中包含的变量对产后女性开始锻炼和维持体重的解释程度。
横断面描述性设计。
在参与者家中收集数据。
对怀孕正常的产后女性进行访谈，并测量其体脂、身体活动和心理社会量表。
（a）运动变化阶段测量，（b）七日回忆法，（c）朋友和家人对运动的支持量表，（d）改变过程问卷，以及（e）体脂测量，包括体重指数和体脂百分比。
40%的人报告每天进行剧烈活动少于1小时，55%的人每天步行少于四个城市街区，52%的人周末进行剧烈活动少于2小时。多元线性回归显示，改变过程对体重指数的贡献率为36%，对腰臀比方差的贡献率为21%。在改变过程中，环境再评价与体重指数显著相关。
女性体重对他人的影响以及肥胖和体育活动对健康影响的信息可以促进产后女性开始锻炼。
