The objectives of this study were to examine relationships between neighbourhood-level and individual-level characteristics and physical activity in deprived London neighbourhoods.
In 40 of the most deprived neighbourhoods in London (ranked in top 11% in London by Index of Multiple Deprivation) a cross-sectional survey (n = 4107 adults aged > = 16 years), neighbourhood audit tool, GIS measures and routine data measured neighbourhood and individual-level characteristics. The binary outcome was meeting the minimum recommended (CMO, UK) 5 × 30 mins moderate physical activity per week. Multilevel modelling was used to examine associations between physical activity and individual and neighbourhood-level characteristics.
Respondents living more than 300 m away from accessible greenspace had lower odds of achieving recommended physical activity levels than those who lived within 300 m; from 301-600 m (OR = 0.7; 95% CI 0.5-0.9) and from 601-900 m (OR = 0.6; 95% CI 0.4-0.8). There was substantial residual between-neighbourhood variance in physical activity (median odds ratio = 1.7). Other objectively measured neighbourhood-level characteristics were not associated with physical activity levels.
Distance to nearest greenspace is associated with meeting recommended physical activity levels in deprived London neighbourhoods. Despite residual variance in physical activity levels between neighbourhoods, we found little evidence for the influence of other measured neighbourhood-level characteristics.
本研究旨在探讨邻里层面和个体层面特征与贫困伦敦社区体力活动之间的关系。
在伦敦最贫困的 40 个社区(按多维贫困指数在伦敦排名前 11%)中进行横断面调查(n=4107 名年龄大于等于 16 岁的成年人),使用邻里审计工具、GIS 测量和常规数据测量邻里和个体层面的特征。二分结局是达到英国推荐的最低(CMO)每周 5×30 分钟的适度体力活动水平。使用多水平模型检验体力活动与个体和邻里层面特征之间的关联。
与居住在 300 米以内可到达绿地的人相比,居住在 300 米以外可到达绿地的人达到推荐体力活动水平的可能性较低;居住在 301-600 米(OR=0.7;95%CI 0.5-0.9)和 601-900 米(OR=0.6;95%CI 0.4-0.8)的人。体力活动的邻里间残差差异较大(中位数比值=1.7)。其他客观测量的邻里层面特征与体力活动水平无关。
距离最近的绿地的距离与贫困伦敦社区达到推荐的体力活动水平有关。尽管邻里间的体力活动水平存在残差差异,但我们几乎没有发现其他测量的邻里层面特征的影响证据。
