Regular exercise to elicit caloric expenditure is an important component for achieving weight loss. The Healthy People 2000 objectives recommend regular sustained physical activity lasting 30 minutes, five days per week (Objective 1.3) particularly for weight loss. Moreover, this recommendation has been restated for weight loss and overall health benefits in the Centers for Disease Control and Prevention / American College of Sports Medicine (CDC/ACSM) statement and Surgeon General's Report (SGR) on Physical ActivitY and Health. Thus, we sought to identify the relative quality, and quantity of physical activity among people trying to lose weight.
Cross-sectional self-reported data from the West Virginia Behavioral Risk Factor Surveillance System (BRFSS) were used. The BRFSS is a state-based telephone survey of adults that uses a multistage cluster design based on the Waksberg method of random-digit dialing. Data froM 2769 men and 4490 women were obtained from the 1992, 1994, and 1996 surveys.
Half (49.6%) of individuals trying to lose weight did not engage in any physical activity. Further, only 15% of respondents trying to lose weight reported exercising regularly. Nevertheless, those trying to lose weight were more likely (OR [odds ratio] = 1.3; 95% CI [confidence interval], 1.14, 1.51, p < 0.001) to exercise regularly than those not trying to lose weight. In particular, women trying to lose weight were significantly more likely (OR = 1.45; 95% CI, 1.22,1.74, p < 0.001) to exercise regularly than women not trying to lose weight. Conversely, men trying to lose weight were no more likely to exercise regularly (p = .23) than men not trying to lose weight. Among respondents who were using exercise for weight loss, only 14.7% were expending > or =1000 kcal/week and 18.2% were expending > or =500 kcal/week. Weekly expenditure rates of > or =1000 kcal/week were more likely to occur among men (17%) than women (13.8%), in younger age groups, and among those with higher educational attainment.
These data suggest that while certain individuals trying to lose weight are more likely to engage in regular physical activity, most persons trying to lose weight have not adopted regular physical activity as part of their weight loss practice. These results suggest that public health efforts to effectively integrate physical activity into weight control practices of West Virginians have been minimally successful.
通过规律运动消耗热量是实现减肥的重要组成部分。《健康人民2000》目标建议进行持续30分钟、每周五天的规律体育活动（目标1.3），尤其是为了减肥。此外，疾病控制与预防中心/美国运动医学学院（CDC/ACSM）的声明以及《美国卫生总署关于身体活动与健康的报告》（SGR）中也重申了这一建议，以实现减肥和整体健康益处。因此，我们试图确定试图减肥人群的身体活动的相对质量和数量。
使用了西弗吉尼亚行为风险因素监测系统（BRFSS）的横断面自我报告数据。BRFSS是一项基于州的针对成年人的电话调查，采用基于瓦克斯伯格随机数字拨号方法的多阶段整群设计。从1992年、1994年和1996年的调查中获取了2769名男性和4490名女性的数据。
一半（49.6%）试图减肥的人没有进行任何体育活动。此外，只有15%试图减肥的受访者报告有规律地锻炼。然而，试图减肥的人比不试图减肥的人更有可能（比值比[OR]=1.3；95%置信区间[CI]，1.14，1.51，p<0.001）进行规律锻炼。特别是，试图减肥的女性比不试图减肥的女性更有可能（OR=1.45；95%CI，1.22，1.74，p<0.001）进行规律锻炼。相反，试图减肥的男性与不试图减肥的男性进行规律锻炼的可能性没有差异（p=0.23）。在使用运动来减肥的受访者中，只有14.7%的人每周消耗≥1000千卡热量，18.2%的人每周消耗≥500千卡热量。每周消耗≥1000千卡热量的情况在男性（17%）中比在女性（13.8%）中更常见，在较年轻的年龄组以及教育程度较高的人群中更常见。
这些数据表明，虽然某些试图减肥的人更有可能进行规律体育活动，但大多数试图减肥的人并没有将规律体育活动作为其减肥实践的一部分。这些结果表明，将体育活动有效纳入西弗吉尼亚人减肥实践的公共卫生努力取得的成功微乎其微。
