Background: Bariatric surgery with the improvement of obesity-related diseases, increases longevity and quality of life and is more cost-effective when compared to non-surgical Procedures. Objective: The aim of this study is to compare the cost-effectiveness of Laparoscopic Sleeve Gastrectomy (LSG) and Laparoscopic Roux-en-Y Gastric Bypass (LRYGB). Method: This study was performed in two stages. Initially, a cross-sectional study was carried out for costing LSG and LRYGB in Rasoul Akram and Bahman hospitals in Tehran in the year 2014. Direct costs for each surgical procedure were calculated according to the average time of surgery in both the private and public sectors. In the second stage, using Outcome (ΔBMI) collected by means of a systematic review study and cost data; cost effectiveness of two surgical procedures was examined by ICER analysis and compared with threshold limit. The Perspective of this analysis was health system. Results: The direct cost of services for LRYGB was $ 2991.5 (98121659 Rials) in the public sector and $4221.9 in the private sector. In LSG, it was $ 1952.9 (64055468 R) in the public sector and $ 3177.2 in the private sector. ICER for LSG was 720.48(23631855 R) and $716.27 (23493924 R) in private and public sector respectively. Conclusion: In this study, LSG procedure when compared to LRYGB was cost effective. The ICER obtained indicated that LSG surgery in comparison to LRYGB was $716.27 (23493924 R) and $720.48(23631855 R) in the public and private sector respectively. Moreover, per unit change in BMI was less than the threshold.

Background: Hypertension is one of the public health challenges. Various risk factors are associated with hypertension, including social demographics, geographical location, health behaviours, and social stress. Interventions in the social determinants of health can improve hypertension and health promotion. Accordingly, different sectors such as agriculture, housing, education, and transportation should cooperate. This systematic review examines policies as a set of activities and actions/interventions aimed at the modification of the social determinants of health to prevent hypertension. Methods: A systematic search will be conducted in Medline (via Ovid), PubMed, EMBASE, Cochrane Library, ProQuest Dissertations & Theses, and scientific Persian databases including SID and Magiran. There will be no time restriction. The quality of selected studies will be assessed using an appropriate Joanna Briggs Institute (JBI) Critical Appraisal Checklists according to the type of studies. Two independent researchers will carry out screening and quality assessment. Disagreement between two researchers will be resolved by a third party. Discussion: Recommendations will be made for policymakers in order to make better evidence-based decisions about the prevention and management of hypertension with regard to the social determinants of health.

Background: Hypertension is one of the most important risk factors of cardiovascular morbidity and mortality that holds a unique place in population health and health care. Objectives: Given the exponential rise of high blood pressure as one of the major health problems, this study aimed to investigate the current situation and provide a strengths, weaknesses, opportunities, and threats (SWOT) analysis in the management of hypertension Methods: A qualitative study of 12 interviews was conducted with policymakers and managers. The sampling method was purposive sampling. Data collection was performed from January to July 2020. A thematic approach was used to analyze the data. The consolidated criteria for reporting qualitative research 32-item (COREQ-32) checklist was applied to ensure quality control in the study design, analysis, and data reporting. Results: A total of 12 factors were identified as SWOT. The most important strengths included universal coverage of health services, provision of team-based care, and self-care training. The weaknesses were related to the therapeutic approach, long-term planning, and continuity of programs. Cooperation of other sectors with the health system and the existence of health management training centers were noted as opportunities to better implement hypertension management programs and confront threats such as conflicts of interest between guilds and organizations and crises. Conclusions: High blood pressure can be prevented. The present direction toward health-oriented policies can be changed in all sectors by taking advantage of the existing strengths and opportunities.
