The prevalence of type-2 diabetes mellitus (T2DM) has increased dramatically during the last 2 decades, a fact driven by the increased prevalence of obesity, the primary risk factor for T2DM. The figures for diabetes in the Arab world are particularly startling as the number of people with diabetes is projected to increase by 96.2% by 2035. Genetic risk factors may play a crucial role in this uncontrolled raise in the prevalence of T2DM in the Middle Eastern region. However, factors such as obesity, rapid urbanization and lack of exercise are other key determinants of this rapid increase in the rate of T2DM in the Arab world. The unavailability of an effective program to defeat T2DM has serious consequences on the increasing rise of this disease, where available data indicates an unusually high prevalence of T2DM in Arabian children less than 18 years old. Living with T2DM is problematic as well, since T2DM has become the 5th leading cause of disability, which was ranked 10th as recently as 1990. Giving the current status of T2DM in the Arab world, a collaborative international effort is needed for fighting further spread of this disease.

Key Words: Diabetes, Arab world, Epidemiology, Etiology, Risk factors and complication

Core tip: The Middle Eastern and North African region has the second highest rate of increases in diabetes anywhere in the world. We comprehensively review type-2 diabetes mellitus (T2DM) in adults and children from 22 Arab speaking countries by reviewing data published from 1980 to 2015; this allowed us to have a better view of the trends in the dramatic increases of T2DM impacting the Arabic region. We also discuss the etiology of this uncontrolled medical crisis and the most commonly reported complications in these Arab speaking countries. Finally, we highlight a number of crucial data that appear to be unavailable but which may be essential for a more comprehensive understanding of the diabetes epidemic sweeping the Arabian region.


Diabetes mellitus (DM) affects more than 382 million people around the world, of whom 90% are diagnosed with type-2 DM (T2DM)[1]. The prevalence of T2DM has increased dramatically during the last 2 decades[1]. The Arab world is not immune from this epidemic in the prevalence of T2DM. In fact, the Middle Eastern and North African region has the second highest rate of increase in diabetes globally, with the number of people with diabetes is projected to increase by 96.2% in 2035[1]. Having T2DM increases the burden for both patients and their caregivers, and of particular concern for Arab governments is the large economic burden of diabetes in terms of cost of treatment, management of complications, disability and loss of productivity[2-4]. The factors associated with T2DM seem more pronounced in the Arab world. Although genetic risk factors can’t be ruled out in the context of T2DM in the Arab world, factors such as obesity, rapid urbanization and lack of exercise are key determinants of the rapid increase of the rate of T2DM among the Arab world[5].

The unavailability of an effective program to contain the dramatic rise in T2DM in the Arab world has led to a serious development in the disease’s course, where current data indicates that T2DM can’t be ruled out in children less than 18 years old. Children diagnosed with T2DM come from all countries in the Arab world and obesity is a hallmark feature in this age group[6,7].

This review will initially address the epidemiology of T2DM in the Arab world, followed by the etiology of the disease, complication and risk factors of T2DM, and finally will discuss some suggestions related to research on T2DM in the Arab world.


We undertook a search of the medical literature using the PubMed, EMBASE and Ovid databases for articles published in English language between 1980 and 2015, and included the following keywords: Diabetes, Arab world, epidemiology, etiology, risk factors and complication, or their corresponding MeSH term synonyms. Among 22 Arabic countries, a total of 2347 papers were identified and screened by title and/or abstract (Figure 1). To ensure that we included the highest number of epidemiological studies from each country, we did not set any limitations on the study design in our exclusion criteria. However, animal or genetic studies, studies not relevant to T2DM, studies on the effects of treatment, and non-primary data such as review articles or adherence studies were excluded (Figure 2). A total of 85 studies were added in the article and were reviewed in full. Among these, 3 studies were concerning Arab immigrants in different countries not listed in Figure 1, and 1 study (not PubMed indexed) was obtained from the references of other paper.

Based on the International Diabetes Federation (IDF) estimates from 2013[1], three countries from the Arabic world are among the top 10 countries worldwide for the prevalence of T2DM; these countries are Saudi Arabia, Kuwait and Qatar. The data obtained from each country in the Arabic world reports variation regarding prevalence of T2DM. However, differences in reported prevalence of T2DM within each country can be attributed to the study design, population and diagnostic methods used to obtain these data. The data clearly confirms that the prevalence of T2DM has increased dramatically during the past two decades. For example, studies from Saudi Arabia in the 80’s indicated that prevalence of T2DM was between 2.4%-4.3%[8,9], while recent a study in Saudi Arabia indicated a dramatic increase in the rate of T2DM with an estimated prevalence of 25.4%[10]. This pattern of massive increases in the rate of T2DM is similar for Iraq, Oman and other countries within the Arabic world (Table 1).

Children and adolescents

Due to the recent recognition of T2DM during childhood, limited data are available worldwide. This unusual age-related disease has become a focus of attention for medical organizations around the world. A recent analysis showed a significant increase of 30.5% in the prevalence of T2DM among children and adolescents aged 10-19 years old in United States from 2001 to 2009[11]. The international society for pediatric and adolescents diabetes has published comprehensive guidelines for screening, diagnosis and treatment of T2DM in children and adolescents[12].

Not surprisingly, data from the Arab world show similar figures for childhood T2DM. Perhaps more worrying is that recent data from Saudi Arabia reports an age-specific prevalence of 1 per 1000 for T2DM in children less than 18 years old[7], which was similar to the highest prevalence found in specific groups (American Indian and African American) in United States[12]. Additional findings on childhood T2DM are summarized in Table 2.

A number of risk factors could account for the uncontrolled rise in T2DM in the Arab world, with genetic factors likely to play an important role. However, a number of modifiable risk factors such as obesity, rapid urbanization and its associated changes in dietary habits and lack of physical activity are also important determinants in the etiology of T2DM. Other considerations such as multiple pregnancies and a lack of health education may be unique challenges in the diabetes epidemic in the Arab world.


Obesity represent a large component in the pathogenesis of T2DM[13], and is by far the primary risk factor for the increased prevalence of T2DM globally[14]. Obesity not only worsens the prognosis of T2DM, but obese diabetics suffer higher rates of microvascular complications and mortality[15-18]. Obesity-related T2DM has been investigated in several countries in the Arab world. In Saudi Arabia, a study of 14252 diabetic patients reported that more than half of the obese diabetics had poor glycemic control[19]. Additionally, the first national health survey in Kuwait indicates that 48% obese males and 77% obese females were also diabetics[20], confirming a significant association between obesity and diabetes [odds ratio (OR) of 2.87] in the Kuwaiti population. In Oman and Qatar, 60.1% and 59.7% of the diabetic patients were obese respectively[21,22]. The average body mass index (BMI) in Palestinian and Lebanese diabetics was 33.7 kg/m2 and 30.8 kg/m2 respectively[23,24]. Nevertheless, obesity is significantly associated with diabetes even in some Arab countries such as Sudan and Tunisia where the prevalence of diabetes can be described as relatively low - the relative risk of developing T2DM was 1.74 (95%CI: 1.32-2.28) in obese Sudanese subjects and the OR of having T2DM was 1.61 (95%CI: 1.34-1.93) in obese Tunisians[25,26].

A recent analysis of 46 Muslim countries (where Muslims represent > 50% of the population) estimated the prevalence of overweight subjects reported that in the Eastern Mediterranean region, females were more likely to be overweight than males (42.1% vs 33%)[27]. Interestingly, those living in Arab countries were 2.92 (95%CI: 2.86-2.97) times more likely to be overweight compared to those living in non-Arab Muslim countries.

Rapid urbanization

Urbanizing of many rural areas within the Arab world carries with it many advantages in term of access to improved medical services, access to education and other “modern” conveniences. There are significant differences in the rate of T2DM between rural and urban communities. For example, an early study in Saudi Arabia found that the prevalence of T2DM in urban communities was 12% and 14% in males and females respectively, which was nearly double the prevalence of T2DM in males and females residing rural areas (7% and 7.7% for males and females respectively)[28]. Another study in Oman indicated that urban residence was significantly associated with T2DM (OR = 1.7, 95%CI: 1.4-2.1), with the prevalence of T2DM was 17.7% and 10.5 in urban and rural areas respectively[21]. Moreover, a systematic review of the prevalence of T2DM in North Africa found that the prevalence of T2DM ranged from 2.6% in rural Sudan to 20.0% in urban Egypt[29].

Dietary habits

The Mediterranean diet is considered to be one of the healthiest food options available, as it contains a variety of fruits, vegetables, grains and olive oil. In fact, several studies have shown significant reduction in the rate of T2DM with the Mediterranean diet[30,31]. However, one is unlikely to obtain the health benefits of the Mediterranean diet without proper adherence, which may be a common habit in most of the Eastern Mediterranean countries. In a comparative risk assessment analysis, data from the United Food and Agricultural Organization was used to estimate the dietary intake of 20 countries in the Middle East and North Africa[32]. These estimates were used to provide a country specific estimates of cardio-metabolic disease mortality secondary to 15 different dietary and metabolic risk factors. This analysis shows that there is suboptimal intake of the “protective” diets (e.g., fruits, vegetables and sea food), and greater consumption of “harmful” diets (e.g., processed meat and trans fatty acids). These results were reflected in the cardio-metabolic disease mortality rate, where non-optimal BMI was the second leading metabolic risk factor for cardio-metabolic disease mortality, accounting for 21% of all cardio-metabolic mortality risk factors, followed by high fasting blood glucose (> 5.3 mmol/L) which accounted for 17% of all cardio-metabolic disease deaths.

Sedentary life style

Numerous studies confirm that physical activity reduces the incidence and/or severity of T2DM[33-35]. Six years of leading an active life coupled with a healthy diet can reduce the incidence of T2DM by 43% in subjects with impaired glucose tolerance followed for 20 years[36]. Another meta-analysis shows that exercise training reduces glycosylated haemoglobin (HbA1c) by 0.66% in type-2 diabetic patients, a percentage that should substantially reduce the complications of T2DM[37]. Not surprisingly, a sedentary life style is one of the most important modifiable risk factors in the Arab world, specifically when comparing the prevalence of highly active subjects in the Arab world with the global data. Among 52746 subject from 20 countries included to study the prevalence of physical activity, 8 countries reported that more than 50% of the population are highly active based on the international physical activity questionnaire[38]. Saudi Arabia, which was the only country from the Arab world that was included in their analysis, is reported to have 26.2% of their population as being highly active. More recent data came from a study over 10 Eastern Mediterranean countries indicating that the highest level of physically active adolescents were in the Emirates (23.9%), while the lowest was in Egypt (9.2%), giving an overall prevalence of physically active adolescents in the Eastern Mediterranean countries of 19%[39].

Other factors

Several factors can explain the unrestrained raise in the rate of T2DM in the Arabian area. Some are attributed to the Eastern cultural heritage from a hundred of years ago, such as multiple pregnancies and cultural barriers for women’s physical activity. However, despite no changes in the traditional risk factors for T2DM in Arabian area, there is an alarming increase in the prevalence of diabetes, particularly within the last two decades - suggesting that recent lifestyle changes may have greater effect on this crisis. The global change impacts the Arab nations even more dramatically than elsewhere: Temperatures that are already scorching on a regular basis are now increased (higher temperatures for longer periods), even more increases in polluted and dusty air. These conditions combine to further discourage many people - regardless of age or gender - from any kind of outdoor activity. The situation is made even worse by the political instability in many of these countries, which affects access to healthy food and medical care.


According to the World Health Organization, diabetes is the 8th leading cause of death in the world[40]. Data published specifically from the Arab world shows a similar trend to that available globally. A recent analysis indicates that diabetes represents the 5th leading cause of death in the Arab world in 2010, compared to it being the 11th leading cause of death in 1990[41]. Living with T2DM is troublesome as well, as diabetes is the 5th leading cause for the disability-adjusted life years in high income Arabic countries in 2010, compared to it being ranked as the 10th reason in twenty years earlier[41]. The studies summarized in Table 3 summarize the most recent data on the prevalence of common complications (retinopathy, nephropathy, neuropathy and peripheral vascular diseases) in diabetic patients from the Arab world.

The high prevalence of T2DM in Arab nations offers an opportunity to better understand the disease and its treatment. Unfortunately, current research in the Arab nations does not match the level of this health crisis in the area. Large portions of critical data information are unavailable in many countries from the Arab world. For instance, predicting the prevalence of T2DM statistically could crucial in formulating a strategic plan for combating the disease, which requires comprehensive knowledge about its current burden, for which data is available only from Tunisia and Saudi Arabia. The Tunisian study revealed that the prevalence of T2DM in Tunisia will reach 26.6% in 2027[42]. Moreover, it predicts that a 20% reduction in obesity and smoking will yield in a 3.3% reduction in T2DM by 2027. On the other hand, the Saudi study indicates that the prevalence of T2DM in Saudi Arabia could reach 44.1% in 2022, a figure which differs significantly from IDF estimates[43].

It would be important to apply the recommendations on physical activity discussed at conference on Healthy Lifestyles and Non-Communicable Diseases in the Arab World and the Middle East, also called the “Riyadh declaration”[44]. To successfully implement the recommendations of the Riyadh declaration, novel research is needed to determine the social determinants for developing diabetes in the Arab world. For instance, a population based longitudinal cohort of 5124 diabetes-free participants in United States revealed that people residing neighborhoods with fewer opportunities for physical activity have nearly double the risk of developing T2DM[45].

Considering the epidemic nature of obesity and T2DM in the Arab world, studies on the ethnic-specific obesity cut-off points for the risk of diabetes are certainly necessary for peoples of the Arab and North African populations. For example, the risk of diabetes increases with BMI values greater than 25 kg/m2 for South Asians, at 27 kg/m2 for African-Caribbeans and at 30 kg/m2 for Europeans[46].


The data obtained from the Arabic world indicates that there is an uncontrolled rise in the prevalence of T2DM over the last two decades, in particular within the Gulf cooperation countries. For example, the prevalence of T2DM in early 1980’s was estimated 2.4%[8], and then increased to 12% in the late 1990’s[28], while recent data from Saudi Arabia shows that the prevalence of T2DM reached 25.4% in 2014. Given that obesity is a major risk factor for developing T2DM, obesity is associated with T2DM in Arab countries even where the prevalence of T2DM is relatively low. In addition, other factors such as rapid urbanization, unhealthy dietary habits and the lack of physical activity are key determinants of T2DM in the area. With this uncontrolled rise in the rate of T2DM in the Arab world, T2DM has now become the 5th leading cause of death in the Arab world. To better estimate the size of this crisis, studies aimed at predicting the rate of T2DM in the future are urgently needed. However, the vast majority of Arabian countries do not provide this important information. In order to successfully contain the uncontrolled rise of T2DM in the Arabian region, one should take advantage of the research conducted in other communities facing similar patterns in the increasing rates of diabetes. For example, genetic studies, ethnic-specific obesity cut-off points for the risk of diabetes studies and community studies to assess the appropriateness of the neighborhoods for physical activity may bring about increased awareness on the epidemic of diabetes sweeping the region-and so help in creating national/regional strategies to successfully limit the widespread firestorm of T2DM ravaging the Arabic region.
