To assess the relation between body mass index (BMI) levels and various lifestyle variables related to physical activity and specific characteristics of a healthy eating pattern, using baseline cross-sectional data from the Wellness IN the Rockies project.
A total of 928 males and 889 females, aged 18-99 y, recruited from six rural communities in Wyoming, Montana, and Idaho.
Using BMI as the criterion, overweight was defined as a BMI >or=25 kg/m(2) and obesity was defined as a BMI >or=30 kg/m(2). All participants in this study completed a questionnaire that elicited sociodemographic information, self-reported height and weight, and data related to specific dietary intakes, eating-related behaviors, and physical activity behaviors and perceptions.
Prevalence of overweight was 70% in men and 59% in women. Increased likelihood of overweight or obesity was associated with greater frequency of the following: drinking sweetened beverages such as soft drinks/soda pop, ordering supersized portions, eating while doing other activities, and watching television. Other predictors were lower frequency of participation in physical activity and the perception of not getting as much exercise as needed.
The increased probability of having a high BMI in individuals who more often eat while doing another activity appears to be a novel finding that will need to be substantiated by additional research. The finding that the vast majority of overweight and obese respondents believed that they do not get as much exercise as needed strengthens the assertion that finding ways to increase participation in physical activity should remain a high priority in obesity prevention and intervention efforts at the community and individual levels.
利用落基山健康项目的基线横断面数据，评估体重指数（BMI）水平与各种与身体活动相关的生活方式变量以及健康饮食模式的特定特征之间的关系。
从怀俄明州、蒙大拿州和爱达荷州的六个农村社区招募了928名年龄在18 - 99岁的男性和889名女性。
以BMI为标准，超重定义为BMI≥25 kg/m²，肥胖定义为BMI≥30 kg/m²。本研究的所有参与者都完成了一份问卷，该问卷收集了社会人口学信息、自我报告的身高和体重，以及与特定饮食摄入量、饮食相关行为、身体活动行为和认知有关的数据。
男性超重患病率为70%，女性为59%。超重或肥胖可能性增加与以下情况的频率增加有关：饮用软饮料等含糖饮料、点超大份食物、边做其他活动边吃东西以及看电视。其他预测因素包括参与身体活动的频率较低以及感觉没有进行所需的运动量。
在边做其他活动边进食的人群中，BMI较高的可能性增加这一发现似乎是一个新发现，需要更多研究加以证实。绝大多数超重和肥胖受访者认为自己没有进行所需运动量这一发现强化了这样一种观点，即在社区和个人层面的肥胖预防和干预工作中，找到增加身体活动参与度的方法仍应是高度优先事项。
