Intestinal parasites among food handlers in Iran: A systematic review and meta-analysis

Abstract Background Poor self-care skills and personal hygiene resulted from limitations in learning and understanding, put intellectually disabled individuals at greater risk for intestinal parasitic infections (IPIs). Despite several regional reports in Iran, the overall burden on IPIs among intellectually disabled individuals is poorly understood. Hence, the present study aimed to estimate the pooled prevalence of IPIs among intellectually disabled individuals in Iran. Methods Using the PRISMA guidelines, we conducted a systematic review and meta-analysis of data retrieved from seven electronic databases (PubMed, Web of Science, Scopus, Embase, and ProQuest for English articles, as well as SID and Magiran for Persian) from their inception up to December 2020. Pooled prevalence was estimated using a random-effects model with a 95% confidence interval (CI) and depicted as a forest plot, while heterogeneity was evaluated using Cochran’s Q-test. Results Exactly 1263 of the 3004 intellectually disabled individuals examined by 14 studies across 10 provinces of Iran were positive for IPIs. Overall pooled prevalence estimate was 41% (95% CI 29–53%) with a range of 21% (95% CI 10–32%) to 68% (95% CI 55–80%) across sub-groups. Entamoeba coli (16.2%; 95% CI 10.3–22%), Blastocystis spp. (12.2%; 95% CI 7.2–17.2%), and Giardia duodenalis (11.9%; 95% CI 7.4–16.3%) were the most prevalent protozoan species. In terms of helminthic agents, the most prevalent species were Enterobius vermicularis (11.3%; 95% CI 6.3–16.3%) followed by Strongyloides stercoralis (10.9%; 95% CI 5.0–16.9%) and Hymenolepis nana (2.8%; 95% CI 0.4–5.2%) Conclusion IPIs are highly prevalent among intellectually disabled individuals in Iran. Improving the health status and implementing infectious disease prevention strategies in rehabilitation centers, health promotion interventions to improve personal hygiene of intellectually disabled individuals, as well as utilize sensitive diagnostic methods besides routine stool examination techniques, and treatment of infected individuals will help in the control of these infections among intellectually disabled individuals.

Abstract Background : Numerous studies have been carried out on assessing the prevalence of intestinal parasites infections (IPIs) among preschool and school-age children in Ethiopia, but there is lack of study systematically gathered and analyzedinformation for policymakers. Therefore, the aim of this systematic review and meta-analysis was to provide a summary on prevalence, geographical distribution and trends of IPIs among preschool and school-age childrenin Ethiopia. Methods :The search were carried out in Medline via PubMed, Scopus, Science Direct, Web of Science, and Google Scholar from 1996to July2019 for studies describing prevalence of IPIs among preschooland school-age children. We conducted meta-regression to understand the trends and the source of heterogeneity and pooled the prevalence using ‘metaprop’ command using STATA software version 14. Results : Eighty-three(83) studies examining 56,786 fecal specimens were included. The prevalence of IPIs was 48 %( 95%CI: 42% to 53%) and showedsignificantly decreasing trends 17% (95% CI: 2.5% to 32%) for each consecutive 6 years) and was similar in males and females. The pooled prevalence in years 1997–2002, 2003–2008, 2009–2014 and >2014 was 71% (95% CI: 57% to 86%), 42% (95% CI: 27% to 56%), 48% (95% CI: 40% to 56%) and 42% (95% CI: 34% to 49%), respectively. Poly-parasitism was observed in 16% (95% CI: 13% to 19 %,) of the cases. Conclusion: Intestinal parasite infections are highly prevalent among preschool and school-age children and well distributed across the regional states of Ethiopia. Southern and Amhara regional states carry the highest burden.We observed significant decreasing trends in prevalence of IPIs among preschool and school-age Ethiopian children over the last two decades.Therefore, this study is important to locate the geographical distribution and identified high risk areas that should be prioritized further interventions, which complement global efforts towards elimination of IPIs infections by 2020
