Context: Infections caused by the hepatitis B virus (HBV) pose a major challenge to the public health and also results in high mortality and morbidity rates in different parts of the world, especially in children. This study performed a systematic review and a meta-analysis of cross-sectional studies conducted during the years 2000-16 to clarify the prevalence of hepatitis B surface antigen (HBsAg) in children and adolescents younger than 16 years of age in EMRO and Middle Eastern (E and M) countries.Evidence Acquisition: Scientific databases including PubMed, Ovid, Scopus, Google Scholar, and Persian databases were searched for relevant articles published from January 1, 2000 to October 31, 2016. Based on the results of homogeneity tests (a significant homogeneity test and a large I2 value) a random effects model was used to aggregate the collected data and calculate the pooled prevalence estimates.Results: We included 20 articles in our meta-analysis. The pooled HBsAg prevalence in children of E and M countries was 2.73% (95% CI: %1.73% - 3.72%). The prevalence rates in the EMRO and Middle Eastern countries were 1.85% (95% CI: 1.27% - 2.43%) and 2.66% (95% CI: 1.31% - 4.01%), respectively. The prevalence rates amongst children in nations considered in more than one study were 0.81% (95% CI: 0% - 1.74%) in Iran, 2.64% (95% CI: 1.63% - 3.64%) in Pakistan, and 5.83% (95% CI: 2.99% - 8.67%) in Turkey.Conclusions: Based on the world health organization classification of HBV prevalence, intermediate HBsAg prevalence rates were detected in children of E and M countries during 2000 - 2016. Nevertheless, the prevalence rates were low in several included countries in mentioned regions.

Background: The prevalence of Hypertension (HTN) in developing countries might have a different pattern in different countries.Objectives: This study aimed at investigating the current pattern of HTN and evaluating its relationship with health complaints in elderly Iranian individuals in 2012.Methods: This cross sectional study used multistage sampling to investigate 1 350 Iranian elderly subjects (≥ 60 years) living in the community. Those elderly, who had a systolic blood pressure (SBP)≥ 140 mmHg and/or diastolic blood pressure (DBP)≥ 90 mmHg and/or those who used antihypertensive drugs during the previous two weeks, were considered as HTN. A face-to-face interview was performed using a structured questionnaire, including demographic factors, awareness, treatment and control of HTN, and health complaints for each individual. Chi-square test and multiple logistic regression analyses were applied to detect the most important variables related to HTN.Results: Hypertension was seen in 48.5% of individuals. Awareness, treatment, and control of HTN were seen in 40.7%, 82.5%, and 30% of individuals, respectively. Elderly individuals with HTN had significantly more experienced visual disturbances (P = 0.03), fecal or urinary incontinence (P = 0.006), nocturia (P = 0.002), attacks of shortness of breath (P = 0.004), and hyperlipidaemia (P < 0.001). After adjusting for potential confounders such as ethnicity, nocturia (OR, 1.34; CI 95%, 1.02 - 1.75) and hyperlipidemia (OR, 1.94; 95% CI, 1.5 - 2.51) remained significantly relevant to HTN.Conclusions: The prevalence of HTN was lower in elderly community-living Iranians than developed countries, yet, was still considerable. Nocturia and hyperlipidemia were the most common health complaints in Iranian elderly with HTN.
