The prevalence of obesity and its attendant complications are on the increase globally-sub-Saharan Africa inclusive. Obesity confers an increased risk of coronary artery disease, type 2 diabetes, ischemic stroke, and some cancers. In Nigeria, several individual reports estimate an exponential increase in the prevalence of overweight and obesity.
In this study, we aimed to estimate the current prevalence of overweight and obesity in Nigeria through a systematic review and meta-analyses.
A systematic review and meta-analysis were conducted on the prevalence of obesity in Nigeria using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) format following searches on major search engines, performed in PubMed, Science Direct, Google Scholar, Africa Journals Online (AJOL), and the WHO African Index Medicus database. Studies on the subject area conducted from the year 2000 to 2018 were included. The forest plot was used to graphically present the results, while confidence interval at 95% was used to display the rates.
A total of 77 articles on the prevalence of obesity involving 107, 781 individuals were used in the study. We found a pooled estimate of overweight of 26.0% (95% CI: 23.0-29.0) and that of obesity as 15.0% (95% CI: 13.0-16.0). There was an increasing trend in the prevalence of obesity in Nigeria from the study especially among urban dwellers.
The prevalence of obesity and overweight in Nigeria is high with a rising trend over the years. A Nigerian national health survey of non-communicable diseases especially the burden of overweight/obesity is recommended to through more light on the subject. There is need for concerted effort to tame the tide of rising obesity rates in Nigeria.
肥胖及其相关并发症在全球范围内，包括撒哈拉以南非洲地区，都呈上升趋势。肥胖会增加患冠状动脉疾病、2型糖尿病、缺血性中风和某些癌症的风险。在尼日利亚，多项独立报告估计超重和肥胖的患病率呈指数增长。
在本研究中，我们旨在通过系统评价和荟萃分析来估计尼日利亚目前超重和肥胖的患病率。
按照系统评价和荟萃分析的首选报告项目（PRISMA）格式，对尼日利亚肥胖患病率进行了系统评价和荟萃分析，在主要搜索引擎上进行搜索，这些搜索引擎包括PubMed、科学Direct、谷歌学术、非洲期刊在线（AJOL）以及世界卫生组织非洲医学索引数据库。纳入了2000年至2018年期间进行的关于该主题领域的研究。采用森林图以图形方式呈现结果，同时使用95%置信区间来显示患病率。
该研究共使用了77篇关于肥胖患病率的文章，涉及107,781人。我们发现超重的合并估计患病率为26.0%（95%置信区间：23.0 - 29.0），肥胖的合并估计患病率为15.0%（95%置信区间：13.0 - 16.0）。从研究中可以看出，尼日利亚肥胖患病率呈上升趋势，尤其是在城市居民中。
尼日利亚肥胖和超重的患病率较高，且多年来呈上升趋势。建议进行尼日利亚全国非传染性疾病健康调查，尤其是关于超重/肥胖负担的调查，以便更清楚地了解该问题。需要共同努力来遏制尼日利亚肥胖率不断上升的趋势。
