Prevalence Rate of Diabetes and Hypertension in Disaster-Exposed Populations: A Systematic Review and Meta-Analysis.

Abstract

Non-communicable diseases (NCD) such as hypertension (HTN) and diabetes mellitus (DM) have been one of the major health problems in the world. The aim of this study was to evaluate the prevalence rate of DM and HTN following natural and man-made disasters that impose significant economic and psychological burdens on human communities. In this systematic and meta-analysis review, all cross-sectional studies that at least one of their objectives was to measure the prevalence of HTN or DM in individuals affected by natural and man-made disasters were included. Literature review was done in international databases including PubMed, Scopus and Web of Science, from database inception to February 17, 2019. The extracted data included the bibliographic characteristics of the article, the age of the participants, number of participants, gender, sample size, outcome, duration of the follow-up, and prevalence of DM and HTN. Data were analyzed by STATA software (version 11) and random effect method and the I2 index were used to investigate heterogeneity between the articles. A total of 16 articles met the inclusion criteria. Based on the quality assessment, 11 papers were categorized as moderate and 5 paper were categorized as high quality. The prevalence of HTN and DM in disaster-exposed populations were 47.35 (CI 95%: 38.53-56.17) and 13.56 (CI 95%: 10.12-17.01), respectively. The results of this study show a high prevalence of HTN and DM in survivors of major disasters, which is higher in comparison to the general population.
