Physical activity is crucial to preventing noncommunicable diseases. This study aimed to provide up-to-date evidence on the epidemiology of insufficient physical activity across Nigeria to increase awareness and prompt relevant policy and public health response.
A systematic literature search of community-based studies on physical inactivity was conducted. We constructed a meta-regression epidemiologic model to determine the age-adjusted prevalence and number of physically inactive persons in Nigeria for 1995 and 2020.
Fifteen studies covering a population of 13 814 adults met our selection criteria. The pooled crude prevalence of physically inactive persons in Nigeria was 52.0% (95% CI: 33.7-70.4), with prevalence in women higher at 55.8% (95% CI: 29.4-82.3) compared to men at 49.3% (95% CI: 24.7-73.9). Across settings, prevalence of physically inactive persons was significantly higher among urban dwellers (56.8%, 35.3-78.4) compared to rural dwellers (18.9%, 11.9-49.8). Among persons aged 20-79 years, the total number of physically inactive persons increased from 14.4 million to 48.6 million between 1995 and 2020, equivalent to a 240% increase over the 25-year period.
A comprehensive and robust strategy that addresses occupational policies, town planning, awareness and information, and sociocultural and contextual issues is crucial to improving physical activity levels in Nigeria.
身体活动对预防非传染性疾病至关重要。本研究旨在提供最新的尼日利亚身体活动不足流行病学证据，以提高认识并促使采取相关政策和公共卫生措施。
对基于社区的身体活动不足研究进行了系统文献检索。我们构建了一个荟萃回归流行病学模型，以确定 1995 年和 2020 年尼日利亚调整年龄后的身体不活跃者的患病率和人数。
符合我们选择标准的 15 项研究涵盖了 13814 名成年人。尼日利亚身体不活跃者的总粗患病率为 52.0%（95%可信区间：33.7-70.4），女性的患病率较高，为 55.8%（95%可信区间：29.4-82.3），而男性为 49.3%（95%可信区间：24.7-73.9）。在各种环境中，城市居民身体不活跃者的患病率明显高于农村居民（56.8%，35.3-78.4）。在 20-79 岁人群中，1995 年至 2020 年间，身体不活跃者的总数从 1440 万人增加到 4860 万人，在 25 年期间增加了 240%。
需要制定一项全面而有力的策略，解决职业政策、城镇规划、意识和信息以及社会文化和背景问题，以提高尼日利亚的身体活动水平。
