目的：关于体重状况（即正常、超重和肥胖）对成年人体力活动（PA）的社会生态相关性的调节影响的研究有限。因此，本研究试图阐明这个问题。设计：在2001年，一个全国性的横截面邮件出面板调查进行了为期3个月的时间在美国。正常体重1867例，（即体重指数（BMI）= 20 - 24.99 kg/ m（2）），2145超重（即BMI = 25 - 29.99 kg/m2），1902例肥胖（即BMI 430 kg/ m（2））成人。除了社会支持（SS）、自我效能（SE）、设施使用和PA外，还进行了各种人口统计学测量。正常体重者的PA显著高于超重者，超重者的PA显著高于肥胖者F（2，5991）= 55.51，P < 0.01。进一步的回归分析表明，较高的SE，SS，在附近的设施，以及这些结构之间的各种相互作用与PA显着正相关。有趣的是，这些关系的强度不同，取决于体重status.CONCLUSION：体重状况需要考虑到社会生态相关的PA时。
OBJECTIVE: Research is limited concerning the moderating influence of weight status ( ie normal, over, and obese) on the social ecological correlates of physical activity ( PA) in adults. Therefore, the present study attempted to shed light on this issue.DESIGN: In 2001, a national cross- sectional mail out panel survey was conducted over a 3- month period in the United States.SUBJECTS: There were 1867 normal weight ( ie body mass index ( BMI) = 20 - 24.99 kg/ m(2)), 2145 overweight ( ie BMI = 25 - 29.99 kg/ m(2)), and 1902 obese ( ie BMI430 kg/ m(2)) adults.MEASURES: Various demographic measurements were taken in addition to social support ( SS), self- efficacy ( SE), access to facilities, and PA.RESULTS: Normal weight individuals engaged in significantly more PA than overweight individuals, who in turn engaged in significantly more PA than obese individuals F( 2,5991) = 55.51, P < 0.01. Further regression analyses showed that higher SE, SS, the access to facilities in a neighborhood, and various interactions among these constructs were significantly and positively associated with PA. Interestingly, the strength of these relationships varied depending on weight status.CONCLUSION: Weight status needs to be taken into consideration when examining social ecological correlates of PA.
