Walking is a key focus of public health interventions yet is particularly uncommon in rural residents. This study's purpose was to determine whether a multilevel community intervention affected rates of moderate physical activity, in particular walking.
A quasi-experimental design examined changes in walking in six rural intervention communities in Missouri and six comparison communities in Arkansas and Tennessee in 2003-2004. Interventions were developed with community input and included individually tailored newsletters; interpersonal activities that stressed social support and health provider counseling; and community-wide events such as fun walks. A dose variable estimated exposure to intervention activities. Primary outcomes were rates of walking and moderate physical activity in the past week.
At follow-up (n = 1531), the percentage of respondents who met the recommendation for walking was the same across the intervention and comparison areas. Among the dependent variables, walking showed some evidence of a positive linear trend across dose categories (P = 0.090). After adjusting for covariates and baseline rates, intervention participants in the moderate and high dose categories were about three times more likely to meet recommended guidelines for walking.
Some evidence of effectiveness was shown for a multilevel intervention approach to promote walking.
步行是公共卫生干预措施的关键重点,但在农村居民中尤为罕见。本研究的目的是确定多层次社区干预是否会影响适度身体活动的比率,特别是步行。
采用准实验设计,研究2003 - 2004年密苏里州六个农村干预社区以及阿肯色州和田纳西州六个对照社区的步行变化情况。干预措施在社区参与下制定,包括个性化定制的时事通讯;强调社会支持和医疗服务提供者咨询的人际活动;以及社区范围的活动,如趣味步行。一个剂量变量估计了对干预活动的暴露程度。主要结局是过去一周内的步行率和适度身体活动率。
在随访时(n = 1531),干预地区和对照地区达到步行建议标准的受访者百分比相同。在因变量中,步行在不同剂量类别中显示出一些呈正线性趋势的证据(P = 0.090)。在调整协变量和基线率后,中等剂量和高剂量类别的干预参与者达到步行推荐指南的可能性大约是其他参与者的三倍。
对于促进步行的多层次干预方法,显示出了一些有效性证据。
