Prevalence of hypertension and its risk factor among cotton textile workers in low-and-middle-income countries: A systematic review protocol
Abstract Background: Cotton workers are exposed to various hazards in the textile industry that might result in different ailments including hypertension (HTN). However, few attempts have been made to systematically review the prevalence of hypertension and its risk factor among cotton textile workers in low-and-middle-income countries (LMICs). The objective of this study will be to evaluate the prevalence of hypertension and its risk factors among adult cotton textile workers in low- and middle-income countries. Methods: We designed and registered a study protocol for a systematic review of descriptive epidemiology data. We will include observational studies (e.g. cross-sectional, cohort, surveys) on the epidemiology of hypertension among adult cotton textile workers in low- and middle-income countries. The primary outcome will be the prevalence of hypertension. Secondary outcomes will be the prevalence of risk factors of hypertension. Literature searches will be conducted in multiple electronic databases (from January 2000 onwards), including PubMed/MEDLINE, CINAHL, Science Direct, and Cochrane Library. Grey literature will be identified through searching conference abstracts, thesis dissertations and public repositories. Two investigators will independently screen all citations, full-text articles, and abstract data. The study methodological quality (or bias) will be appraised using an appropriate tool. If feasible, we will conduct random effects meta-analysis. Additional analyses will be conducted to explore the potential sources of heterogeneity (e.g. age, gender, years of service, textile department). Discussion: This review will highlight the proportion of hypertension along with its risk factor among cotton textile workers in LMICs. Given that, some of the factors can be prevented in this high-risk population, we will call on health, experts to prioritize policies and commission and conduct programs to support the improvement in their health. This systematic review will identify, evaluate and integrate evidence on the prevalence and risk factors of hypertension among adult cotton textile workers in low- and middle-income countries. Our findings will be made publicly available in a repository and published in a peer-reviewed journalSystematic Review Registration: The present protocol has been registered within the PROSPERO database (registration ID: CRD42020167175)
