Understanding how neighborhood environments are related to older adults' quality of life (QoL) and physical activity (PA) is important for public health actions on healthy ageing in sub-Saharan Africa. We examined associations of perceived neighborhood environment attributes with QoL among older adults in Nigeria and investigated the moderating effects of PA on these associations. We conducted a cross-sectional study of 353 older adults (mean age = 68.9 ± 9.1 years) selected from 5 high- and low-income communities in Maiduguri, Nigeria. QoL, attributes of the neighborhood environments and PA were self-reported using validated questionnaires. Multi-level models were used to examine the direct associations between neighborhood environment attributes and each of the four domains of QoL (physical health, psychological health, social relationships, and environmental health), as well as the moderating effects of leisure-time and total PA. Seven of nine neighborhood environment features were positively associated with multiple domains of QoL. Residential density, land-use diversity, land-use mix-access, walking infrastructure, traffic safety and 'overall walkability' were positively related to both or either physical health and environmental health QoL among those who are physically active. In contrast, walking infrastructure, traffic safety, and 'overall walkability' were negatively related to psychological health QoL among those physically active Our findings suggest being physically active moderates the association of neighborhood environments with QoL among Nigerian older adults. We suggest that designing age-friendly communities and simultaneously promoting PA may be needed to improve QoL and help prepare the Nigerian society for the predicted increase in the older adult population.
了解邻里环境如何与老年人的生活质量（QoL）和身体活动（PA）相关，对于撒哈拉以南非洲地区促进健康老龄化的公共卫生行动至关重要。我们研究了尼日利亚老年人感知到的邻里环境属性与生活质量之间的关联，并调查了身体活动对这些关联的调节作用。我们对从尼日利亚迈杜古里的5个高收入和低收入社区中选取的353名老年人（平均年龄 = 68.9 ± 9.1岁）进行了一项横断面研究。使用经过验证的问卷对生活质量、邻里环境属性和身体活动进行了自我报告。采用多层次模型来检验邻里环境属性与生活质量四个领域（身体健康、心理健康、社会关系和环境卫生）中每个领域之间的直接关联，以及休闲时间身体活动和总身体活动的调节作用。九个邻里环境特征中的七个与生活质量的多个领域呈正相关。居住密度、土地利用多样性、土地利用混合可达性、步行基础设施、交通安全和“整体步行适宜性”与身体活跃者的身体健康和环境卫生生活质量中的一个或两个均呈正相关。相比之下，步行基础设施、交通安全和“整体步行适宜性”与身体活跃者的心理健康生活质量呈负相关。我们的研究结果表明，身体活动会调节尼日利亚老年人邻里环境与生活质量之间的关联。我们建议，可能需要设计对老年人友好的社区并同时促进身体活动，以提高生活质量，并帮助尼日利亚社会为预测的老年人口增长做好准备。
