To examine trends in walking among adults in 31 states.
Trends by sociodemographic strata were analyzed from respondents who participated in the Behavioral Risk Factor Surveillance System (BRFSS).
The prevalence of walking among men increased 3.8% (95% confidence interval [CI]=2.4-5.2), from 26.2% (95% CI=25.1-25.3) in 1987 to 30.1% (95% CI=29.4-30.8) in 2000. In women, walking increased 6.6% (95% CI=5.4-7.8), from 40.4% (95% CI=-39.4-41.1) to 46.9% (95% CI=46.2-47.6) during the same time period. However, the prevalence of walking three times a week for 30 minutes duration remained constant across all years. The largest increases occurred in minority subpopulations: 8.7% (95% CI=3.2-14.2) in Hispanic women, 8.5% (95% CI=4.4-12.6) non-Hispanic black women, and 7.0% (95% CI=2.3-11.7) in non-Hispanic black men. Walking was the most frequently reported activity among adults who met the national recommendations for regular physical activity (defined as five or more times a week for > or =30 minutes per session).
Given the acceptability of walking across all sociodemographic subgroups, efforts to increase the frequency of walking could markedly increase the percentage of U.S. adults who engage in regular physical activity, a national priority identified in the Healthy People 2010 objectives for the nation.
研究31个州成年人的步行趋势。
对参与行为危险因素监测系统（BRFSS）的受访者按社会人口统计学分层分析趋势。
男性步行的患病率从1987年的26.2%（95%置信区间[CI]=25.1 - 25.3）增至2000年的30.1%（95% CI=29.4 - 30.8），增长了3.8%（95% CI=2.4 - 5.2）。在同一时期，女性步行患病率从40.4%（95% CI=-39.4 - 41.1）增至46.9%（95% CI=46.2 - 47.6），增长了6.6%（95% CI=5.4 - 7.8）。然而，每周步行三次、每次持续30分钟的患病率在所有年份保持不变。增幅最大的是少数族裔亚人群体：西班牙裔女性为8.7%（95% CI=3.2 - 14.2），非西班牙裔黑人女性为8.5%（95% CI=4.4 - 12.6），非西班牙裔黑人男性为7.0%（95% CI=2.3 - 11.7）。在达到国家定期体育活动建议（定义为每周五次或更多次、每次≥30分钟）的成年人中，步行是最常报告的活动。
鉴于步行在所有社会人口统计学亚组中的可接受性，增加步行频率的努力可能会显著提高参与定期体育活动的美国成年人的比例，这是《2010年美国人健康目标》中确定的国家优先事项。
