INTRODUCCIÓN
In less than a generation, diabetes mellitus (DM) has become one of the most prevalent noncommunicable diseases affecting humans around the world. Jaacks, Siegel, Gujral, and Venkat Narayan (2016) concluded that “Diabetes, a major cause of death, morbidity, and health care expenditures, now represents one of the greatest threats to global health and development”¹. DM’s impact on the global health status can be attributed to the 1.5 million deaths associated with it around the world each year².
There is no question that DM rates are on the rise around the world. The World Health Organization (WHO) estimated that there are some 422 million adults living with diabetes in 2014, roughly 1 in every 11 persons², and that number is expected to increase to 642 million by 2040.3 In fact, diabetes has become a “global menace,” having increased in high-income countries (HICs) and low and middleincome countries (LMICs) by 45% since 1990³. Birn et al. (2017) continued to state, “In recent years, WHO’s Commission on Social Determinants of Health (2008) has called for incorporating measures of health inequity into planning, policy, and technical work, including data collection, at WHO and in member countries”³.
In the US, according to the Centers for Disease Control and Prevention estimates, some 30 million Americans are living with diabetes, and of that number, 23.1 million had a diagnosis, and 7.2 million were undiagnosed^4,5. Additional reports have stated that 1.5 million new cases of diabetes emerge each year within the U.S. population age 20 years or older, with significant disparities observed by race/ethnicity 5. It is also estimated that 25.2%, or 12.0 million seniors age 65 and older have diabetes, diagnosed and undiagnosed⁵. Regarding diabetes for Americans under the age of 20, approximately 19,300 are estimated to have diagnosed diabetes⁵. In addition, in 2015, 84.1 million people age 18 and older had prediabetes in the US5. Graphic 1.

Increased DM rates in LMICs present a serious economic and social challenge for individuals and nations. The WHO suggested that diabetes is a major cause of blindness, kidney failure, heart attacks, stroke and lower limb amputations around the world. “In pregnancy, poorly controlled diabetes increases the risk of fetal death and other complications”², since individuals in LMICs may not have access to treatment or prevention strategies designed to reduce morbidity and mortality from the disease, those affected may experience preventable morbidity and mortality. Mills (2014) stated, “Lack of financial protection for the costs of health care means that approximately 100 million people are pushed below the poverty line each year by payments for health care, and many more will not seek care because they lack the necessary funds”⁶. Birn et al. (2017) asserted that Type 2 diabetes is a largely preventable disease, and many of the ramifications of diabetes can be delayed, and possibly avoided completely³. Jaacks et al. (2016) stated that approximately one-half of those affected by diabetes world-wide are undiagnosed¹.
DISEASE OVERVIEW
Diabetes mellitus is a metabolic disorder “characterized by disturbances in blood sugar regulation and metabolism”3 and occurs when the pancreas produces little or no insulin (Type 1), or when the body “cannot effectively use the insulin that the pancreas produces” (Type 2)^2,3. There are three types of diabetes: Type 1, Type 2, and gestational diabetes mellitus (GDM). The majority of diabetics, 90%, have Type 2 diabetes³.
Type 1 diabetes is a condition where the body’s immune system destroys beta cells in the pancreas (cells responsible for insulin production). As a result, the pancreas produces little or no insulin leading patients to require daily insulin intake. The most common form of DM, Type 2, occurs when a person cannot effectively use the insulin that the pancreas produces3. Type 2 diabetes is related to age, family history, physical inactivity, ethnicity, and in some cases results from GDM.
RISK FACTORS
Birn et al. (2017) asserted that the main behavioral and biological determinants of diabetes are diets of processed sugars and fats, low physical activity levels, and overweight and obesity³. Beaubien (2017) stated that Type 2 diabetes is oftentimes considered a lifestyle, as it is much more likely to develop in people who are overweight7. Birn et al. (2017) stated that as modernization has occurred in countries, populations have been challenged with maintaining physical exercise levels and traditions of healthy eating, “due to the industrialization of agriculture, corporatization of food production (with local production shifted to export crops), global marketing of foods high in sugar and saturated fats, built environments designed for motorized vehicles, and the shift from agriculture to factory and service sector work”³. In addition, Jaacks et al. (2016) stated, “The onset of type 2 diabetes is shifting to younger ages in most parts of the world, thus pediatricians should be trained to recognize the risk factors and intervene”¹.
RESULTS - RECOMMENDATIONS
As one of the four major non-communicable diseases (NCDs), DM has attracted a great deal of attention from global health authorities. In fact, the WHO has developed a strategy to address increasing rates of DM including prevention, management, access to essential medicines, and surveillance. Furthermore, the WHO (2016) has developed global systemic recommendations (Figure 1) designed to improve national capacity for prevention and control of DM2.

PREVENTION METHODS

1. EATING HEALTHFULLY
Consuming whole grains, which are rich in minerals and essential vitamins, two times per day may decrease the risk for Type 2 diabetes by up to 21%⁸. Similarly, decreasing refined grains and carbonated beverages (e.g., sodas) is recommended to decrease the chance of developing diabetes. Ross (2012) stated, “Because refined carbohydrates made from sugar and white flour rapidly increase insulin levels, they can permanently exhaust the pancreas (the insulinproducing organ), causing diabetes”⁹. The author continued to note that eating large quantities of sugar can cause the loss of certain minerals, in particular, chromium. Experts also recommend limiting red meat consumption and replacing it with other forms of protein^5,10. The US Office of Disease Prevention and Health Promotion documented recommendations for healthy eating patterns, including consumption of a variety of vegetables from all of the subgroups, fruits, whole grains, fat-free or low-fat dairy products, a variety of protein foods, oils, and limiting saturated fats, trans fats, added sugars, and sodium¹⁴.
2. BEING PHYSICALLY ACTIVE
A brisk walk on a daily basis can decrease the chance for Type 2 diabetes by 30%. Current recommendations from the Centers for Disease Control and Prevention (CDC, 2018b), and the ODPHP (2019b) for physical activity include:
• For adults, at least 2 hours and 30 minutes each week of aerobic physical activity at a moderate level OR 1 hour and 15 minutes each week of aerobic physical activity at a vigorous level for adults 18-64. Adults should also engage in strengthening activities, like push-ups, sit-ups and lifting weights, at least 2 days a week¹⁵.
• For youth ages 6-17, 60 minutes or more of physical activity each day is recommended. Most of the 60 minutes should be either moderate or vigorous intensity aerobic physical activity, and should include vigorous-intensity physical activity at least 3 days a week. As part of their 60 or more minutes of daily physical activity, children and adolescents should include muscle-strengthening activities, like climbing, at least 3 days a week and bonestrengthening activities, like jumping, at least 3 days a week for children and adolescents ages 6-17¹⁵.
• The new ODPHP guidelines for children ages 3-5 years stated that children pre-school aged should be physically active throughout each day, aiming for at least 3 hours per day of active play, light, moderate, or vigorous intensity (ODPHP, 2019b)¹¹.
3. AVOIDING EXCESSIVE WEIGHT
Excess weight increases the chances of diabetes seven times and up to 40 times for those who are obese. Decreasing body weight by 7-10% of weight can decrease risk for diabetes by 50%^5,12.
• Checking blood glucose. The American Diabetes Association (2018) recommends glucose screening for those under 45 and overweight with a risk factor such as sedentary lifestyle or a family history of diabetes⁵.
• Following medical advice.

CONCLUSION
In less than a generation, diabetes has become a growing global concern, with rates increasing by over 45% since 1990³. The authors continued to posit that the behavioral and biological determinants of diabetes include diets laden with fat and processed sugar, low levels of physical exercise, and overweight and obesity. A comprehensive approach integrating health care policy, health promotion, and health education is necessary for the prevention and subsequent treatment of diabetes around the world. As stated by Pasteur (1876), “Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world”¹³.
