Introduction: Arab populations have many similarities and dissimilarities. They share culture, language and religion but they are also subject to economic, political and social differences. The purpose of this study is to understand the causes of the rising trend of diabetes prevalence in order to suggest efficient actions susceptible to reduce the burden of diabetes in the Arab world. Method: We use principal component analysis to illustrate similarities and differences between Arab countries according to four variables: 1) the prevalence of diabetes, 2) impaired glucose tolerance (IGT), 3) diabetes related deaths and 4) diabetes related expenditure per person. A linear regression is also used to study the correlation between human development index and diabetes prevalence. Results: Arab countries are mainly classified into three groups according to the diabetes comparative prevalence (high, medium and low) but other differences are seen in terms of diabetes-related mortality and diabetes related expenditure per person. We also investigate the correlation between the human development index (HDI) and diabetes comparative prevalence (R = 0.81). Conclusion: The alarming rising trend of diabetes prevalence in the Arab region constitutes a real challenge for heath decision makers. In order to alleviate the burden of diabetes, preventive strategies are needed, based essentially on sensitization for a more healthy diet with regular exercise but health authorities are also asked to provide populations with heathcare and early diagnosis to avoid the high burden caused by complications of diabetes.

Worldwide, diabetes is affecting 370 million people, causing nearly five million deaths and absorbing more than 471 billion USD per year. Mathematical models have been developed to simulate, analyse and understand the dynamics of β-cells, insulin and glucose. In this paper, we consider the effect of genetic predisposition to diabetes on dynamics of β-cells, glucose and insulin. We assume that the β-cell dynamics is governed by the differential equation:

Diabetes is a chronic disease with a huge and growing socioeconomic burden affecting individuals, families and the whole society. In this paper, we propose an optimal control approach modeling the evolution from pre-diabetes to diabetes with and without complications. We show the existence of an optimal control and then use a numerical implicit finite-difference method to monitor the size of population in each compartment. Our model shows that, using optimal control, the number of diabetics with and without complications can be significantly reduced in a period of 10 years.

Background: In the WHO Eastern Mediterranean region, nearly one million deaths are caused by cardio-vascular diseases every year. During the last decade, the number of deaths caused by stroke increased by 23%. Most cardiovascular diseases can be prevented by addressing behavioural risk factors such as tobacco use, alcohol, unhealthy diet, physical inactivity, and metabolic risk factors like obesity, high blood pressure, diabetes and raised lipids. Methods: This is a systematic review on cerebrovascular diseases and associated risk factors in WHO Eastern Mediterranean countries. Medline, Science Direct, and other sources were used to get peer reviewed papers dealing with the review theme. The search was limited to publications between 1990 and 2013 (30th June). Results and Discussion: According to the inclusion criteria, 45 papers were included in the present review. The prevalence was found greater than 50% in 38 studies for hypertension, greater than 25% in 36 studies for diabetes, greater than 15% in 26 studies for smoking and greater than 25% in 19 studies for dyslipidemia. It was also indicated that

Due to its chronic nature with severe complications, diabetes needs costly prolonged treatment and care. The high economic burden of diabetes is particularly threatening low and middle income countries. Worldwide, studies have shown that the cost of diabetes per person is much higher than the per capita health expenditure. This study is the first to estimate the direct and indirect cost of diabetes in Morocco. The direct cost of diabetes was computed by assuming three scenarios of prices (low, medium and high) due to different prices of insulin, oral drugs and other items used in diabetes treatment and care. Indirect costs of diabetes were estimated by the lifetime forgone earnings caused by premature death and disability due to diabetes. The direct cost of diabetes in Morocco was estimated to be between US $0.47 and US $1.5 billion whereas the indirect cost was estimated to be around US $2 billion accounting for 57% of the total cost of diabetes under the high cost scenario, 69% under the medium scenario and 81% under the low cost scenario. The average per capita indirect cost was estimated to be US $1113, relatively higher than the direct cost of diabetes which was seen to vary from US$ 259 to US $830. The results yielded by this study were compared to those obtained by similar studies in different regions and countries of the world. As a conclusion, the findings of this study indicate a high economic burden of diabetes and stress the importance that Moroccan health decision makers should give to sensitisation, early diagnosis and treatment of diabetes especially with the crucial growing trend of diabetes prevalence.

BackgroundOver the last two decades, Moroccan authorities launched a number of actions and strategies to enhance access to health services and improve health outcomes for the whole population in general and for mother and child in particular. The Ministry of Health launched the action plans 2008–2012 and 2012–2016 and created the maternal mortality surveillance system. The Moroccan government opted for national health coverage through a mandatory health insurance and a scheme of health assistance to the poorest households. Other initiatives were devoted indirectly to health by acting on social determinants of health and poverty reduction. In this paper, we present results of an evaluation of interventions and programmes and their impact on health inequity in Morocco.MethodWe used data provided by national surveys over the last decades, information released on the website of the Ministry of Health, documentation published by the Moroccan government and international reports and studies related to Morocco and published by international bodies like the World Health Organisation, United Nations Development Programme, United Nations Population Fund, UNICEF, UNESCO and the World Bank.A short review of scientific publications was also carried out in order to select papers published on health equity, social determinants, health system and interventions in primary health in Morocco.Inferential and descriptive statistics (including principal component analysis) were carried out using software SPSS version 18.ResultsThe findings indicate that substantial achievements were obtained in terms of access to health care and health outcomes for the whole Moroccan population in general and for mothers and children in particular. However, achievements are unfairly distributed between advantaged and less advantaged regions, literate and illiterate women, rural and urban areas, and rich and poor segments of the Moroccan population.DiscussionStudies have shown that it is difficult to trace the effect of a primary health intervention on the access to health care due to synergetic and overlapping effect of interventions and initiatives aiming to improve the wellbeing of the Moroccan population. Descriptive and inferential statistics were used to illustrate the correlation existing between different variables measuring access to health and health outcomes on one side and variables like income, education, employment and health staff on the other side.ConclusionIn Morocco, average access to health care and services as well as health outcomes have improved during the last decades. However, socio-economic inequalities and health inequity are persistent. The present study indicates that urgent and efficient actions on social determinants of health are needed in order to sustain average achievements and improve health equity for the whole Moroccan population.
