BACKGROUND Although there are numerous studies on the global prevalence of cardiometabolic risk factors (CMRFs) in military personnel, the pooled prevalence of CMRFs in this population remains unclear. We aimed to systematically review the literature on the estimation of the global prevalence of CMRFs in the military population. METHODS We simultaneously searched PubMed and NLM Gateway (for MEDLINE), Institute of Scientific Information (ISI), and SCOPUS with using standard keywords. All papers published up to March 2018 were reviewed. Two independent reviewers assessed papers and extracted the data. Chi-square-based Q test was used to assess the heterogeneity of reported prevalence among studies. The overall prevalence of all CMRFs, including overweight, obesity, high low-density lipoprotein (LDL), high total cholesterol (TC), high triglyceride (TG), low high-density lipoprotein (HDL), hypertension (HTN) and high fasting blood sugar (FBS) was estimated by using the random effects meta-analysis. A total of 37 studies met the eligibility criteria and were included in the meta-analysis. RESULTS According the random effect meta-analysis, the global pooled prevalence (95% confidence interval) of MetS, high LDL, high TC, high TG, low HDL and high FBS were 21% (17-25), 32% (27-36), 34% (10-57), 24% (16-31), 28% (17-38) and 9% (5-12), respectively. Moreover, global pooled prevalence of overweight, generalized obesity, abdominal obesity and HTN were estimated to be 35% (31-39), 14% (13-16), 29% (20-39) and 26 (19-34), respectively. CONCLUSIONS The overall prevalence of some cardio-metabolic risk factors was estimated to be higher in military personnel. Therefore, the necessary actions should be taken to reduce risk of developing cardiovascular diseases. SYSTEMATIC REVIEW REGISTRATION NUMBER IN PROSPERO CRD42018103345.

军事人群中心脏代谢危险因素的全球患病率：系统评价和荟萃分析。

背景技术尽管对军事人员中心脏代谢危险因素（CMRF）的全球患病率进行了许多研究，但该人群中CMRF的合并患病率仍不清楚。我们旨在系统地回顾有关估计军人中CMRF的全球患病率的文献。方法我们使用标准关键字同时搜索PubMed和NLM Gateway（用于MEDLINE），科学信息研究所（ISI）和SCOPUS。审查了截至2018年3月的所有论文。两名独立的审稿人评估了论文并提取了数据。基于卡方的Q检验用于评估研究中报告的患病率的异质性。所有CMRF的总体患病率，包括超重，肥胖，高低密度脂蛋白（LDL），高总胆固醇（TC），使用随机效应荟萃分析评估了高甘油三酸酯（TG），低高密度脂蛋白（HDL），高血压（HTN）和高空腹血糖（FBS）。共有37项研究符合入选标准，并纳入荟萃分析。结果根据随机效应荟萃分析，MetS，高LDL，高TC，高TG，低HDL和高FBS的全球合并患病率（95％置信区间）分别为21％（17-25），32％（27- 36），34％（10-57），24％（16-31），28％（17-38）和9％（5-12）。此外，全球合并的超重，全身性肥胖，腹部肥胖和HTN患病率估计为35％（31-39），14％（13-16），29％（20-39）和26（19-34），分别。结论军事人员中某些心血管代谢危险因素的总体患病率较高。因此，应该采取必要的措施以减少患心血管疾病的风险。PROSPERO CRD42018103345中的系统审核注册号。
