Abstract

For this meta-analysis, the aim is to estimate the prevalence and to determine the factors associated with changes in this prevalence in the world. A systematic review of PubMed/Medline, ISI Web of Knowledge, Scopus, and Science Direct, SID, and Google Scholar from 2011 to April 2020 was performed. Point prevalence was analyzed with a 95% confidence interval. The variances of each study were calculated using a two-sentence distribution formula, and the heterogeneity between the studies was assessed by the Q-Cochran test with a significance level of less than 0.1. Also, the index of changes attributed to I² was examined. Due to the heterogeneity between the studies, the random-effects model was used to combine the results of the studies. All statistical analyses were performed by the STATA software version 11 using Meta-Analysis commands. The significance level of the tests was considered to be P < 0.05. The prevalence of mortality in motorcyclists in six studies was reported to be 12% (0.05-0.18 = 95% CI). We stratified this study by participant geographical region and age group. In this study, the highest prevalence of mortality was in the under-30 age group. Furthermore, planning educational campaigns and advertisements by state authorities that are pointing out the harmful effects of motorcyclists' cocaine and/or other substances consumption is necessary.

摘要

对于这项荟萃分析，目的是估计流行率并确定与世界流行率变化相关的因素。对 2011 年至 2020 年 4 月的 PubMed/Medline、ISI Web of Knowledge、Scopus 和 Science Direct、SID 和 Google Scholar 进行了系统评价。用 95% 的置信区间分析点患病率。每项研究的方差采用两句分布公式计算，研究间的异质性采用Q-Cochran检验，显着性水平小于0.1。此外，归因于 I ^{2的变化指数}进行了检查。由于研究之间的异质性，随机效应模型用于组合研究结果。所有统计分析均由 STATA 软件版本 11 使用 Meta-Analysis 命令执行。检验的显着性水平被认为是P < 0.05。据报道，在六项研究中，摩托车手的死亡率为 12%（0.05-0.18 = 95% CI）。我们按参与者的地理区域和年龄组对这项研究进行了分层。在这项研究中，死亡率最高的是 30 岁以下年龄组。此外，有必要由国家当局规划教育活动和广告，指出摩托车手使用可卡因和/或其他物质消费的有害影响。
