OBJECTIVES
We examined temporal and regional trends in the prevalence of health lifestyles in the United States.
METHODS
We used 1994 to 2007 data from the Behavioral Risk Factor Surveillance System to assess 4 healthy lifestyle characteristics: having a healthy weight, not smoking, consuming fruits and vegetables, and engaging in physical activity. The concurrent presence of all 4 characteristics was defined as a healthy overall lifestyle. We used logistic regression to assess temporal and regional trends.
RESULTS
The percentages of individuals who did not smoke (4% increase) and had a healthy weight (10% decrease) showed the strongest temporal changes from 1994 to 2007. There was little change in fruit and vegetable consumption or physical activity. The prevalence of healthy lifestyles increased minimally over time and varied modestly across regions; in 2007, percentages were higher in the Northeast (6%) and West (6%) than in the South (4%) and Midwest (4%).
CONCLUSIONS
Because of the large increases in overweight and the declines in smoking, there was little net change in the prevalence of healthy lifestyles. Despite regional differences, the prevalence of healthy lifestyles across the United States remains very low.
目的
我们在美国考察了健康生活方式的流行程度在时间和地域上的变化趋势。
方法
我们使用了来自行为风险因素监测系统（1994 年至 2007 年的数据），评估了 4 种健康生活方式特征：拥有健康体重、不吸烟、摄入水果和蔬菜、以及进行身体活动。同时拥有这 4 个特征被定义为整体健康的生活方式。我们使用逻辑回归来评估时间和地域趋势。
结果
不吸烟（增加 4%）和健康体重（减少 10%）的个体比例显示出从 1994 年到 2007 年最强的时间变化。水果和蔬菜的摄入量或身体活动量几乎没有变化。健康生活方式的流行程度随时间的推移略有增加，且在地域上有适度的差异；2007 年，东北部（6%）和西部（6%）的比例高于南部（4%）和中西部（4%）。
结论
由于超重的大幅增加和吸烟的减少，健康生活方式的流行率几乎没有净变化。尽管存在地域差异，但美国整体健康生活方式的流行率仍然非常低。
