In recent decades, non-insulin dependent diabetes mellitus (NIDDM) has become a major public health problem in several parts of the world. A complex disorder, NIDDM is associated with an increased risk of blindness, coronary heart disease, peripheral vascular disease, and kidney failure (1). The epidemiology of NIDDM is providing new insights into many aspects of this disease, including prevalence, incidence, morbidity, and mortality (2). My objective is to explain the high prevalence of a NIDDM susceptible genotype(s) in several distinct populations: American Indians, Australian Aborigines, and Pacific Islanders. The susceptible genotype may have been selected into these populations because of unusually frequent food shortages that occurred during the initial colonization of 'new worlds'. NIDDM has been shown to have a strong genetic component (3) that may include a 'thrifty' genotype(s) (4,5). The 'thrifty' genotype(s) may have once allowed founding populations to survive feast' and 'famine' conditions for several generations. With an assured food supply and a sedentary lifestyle, however, the 'thrifty' genotype(s) becomes disadvantageous, leading to obesity, increased insulin resistance, beta cell decompensation, and NIDDM (3,6).

Non-insulin-dependent diabetes mellitus is epidemic among African-American women in the United States; reports of its prevalence among African Americans range from 50% to 60% higher than among whites. African Americans also incur higher rates of diabetes-related complications such as blindness, end-stage renal disease, and amputations. Data indicate that non-insulin-dependent diabetes among African Americans is associated with lower socioeconomic status and with obesity. Because obesity has been hypothesized as contributing to the growing numbers of non-insulin-dependent diabetics among African-American women, new strategies are urgently needed to promote weight loss in this population. Community organization can broaden health education and facilitate behavior change toward development of life- and self-mastery skills. Specific strategies of this approach include (1) integrating community values into health messages, (2) facilitating neighborhood "ownership" and decision-making, (3) utilizing existing formal and informal networks, and (4) empowering individuals and community. Community organization may be a promising strategy among low-income minority communities to reduce the risk of non-insulin-dependent diabetes by promoting changes in dietary patterns, because it ensures that the health messages and programs that emerge will be consistent with existing sociocultural norms and beliefs.

The prevalences of risk factors and angiopathy were studied in 260 diabetic patients, 100 females and 160 males, 35-54 years old, in Uppsala. The prevalence, in females and males separately, of hypertension (WHO-criteria) was 46-34%, of hypercholesterolaemia (greater than or equal to 6.7 mmol.l-1) 32-29%, and of obesity (relative BMI greater than or equal to 120%) 25-20%. Those smoking greater than 15 cigarettes/day were 11-20%. Mean HbA1 was 10.6-10.5%. The prevalence of angina pectoris was 11-6%, of possible infarction 4-6%, and of major ECG abnormalities 6-4%. Large vessel (cardiovascular) disease was independently related to HbA1 (strongly), hypertension, cholesterol, age and familial NIDDM. The prevalence of severe retinopathy (blindness, new vessels or large hemorrhage) was 0% with 7-13 years of diabetes duration, and 26% with greater than or equal to 14 years of duration. The prevalence of severe proteinuria was 4% with 7-13 years of diabetes duration, and 15% with greater than or equal to 14 years of duration. Small vessel (retinopathy and nephropathy) disease was independently related to diabetes duration (strongly), HbA1 and hypertension. The data were discussed related to data from the London, Berlin and Tokyo centres of the WHO Multinational Study of Vascular Disease in Diabetics, using the same study protocol in the present study.

The cardiovascular risk profile was assessed in all 208 diabetics accepted for dialysis in 28 German dialysis centres from 1985-1987 (104 men, 104 women, mean age 60 [22-82] years). 71 patients had type 1 and 128 type 2 diabetes, and 9 maturity onset diabetes of the young. Of 169 patients, 164 (97%) had hypertension (median systolic blood pressure at start of dialysis 200 [120-280] mm Hg). Only 74 patients (44%) were on continuing anti-hypertensive medication. Median serum cholesterol was 225 (66-424) mg/dl, LDL-cholesterol 158 (43-335) mg/dl and HDL-cholesterol 32 (10-67) mg/dl. In patients with a history of myocardial infarction (n = 26) the median cholesterol concentration was 269 (126-424) mg/dl, while in those with no history of myocardial infarction (n = 132) it was 221 (66-280) mg/dl (P less than 0.05). Only 5% of the patients had received lipid lowering therapy. Out of 175 patients, 65 (37%) had a history of smoking, and 25 (14%) were still smokers at the start of dialysis. There was a strong association between smoking history and amputations. Only 98 of 208 patients (47%) had had a specialist ophthalmological examination in the 12 months preceding the start of dialysis. Proliferative retinopathy was present in 33 out of 53 (62%) type 1 and 15 out of 98 (15%) type 2 diabetics. Out of 22 patients with unilateral or bilateral blindness, 2 (10%) had received no photocoagulation. - This investigation reveals a need for better medical care of diabetics with pre-end-stage renal failure.

Diabetes mellitus and hypertension constitute two powerful independent risk factors for cardiovascular, renal and atherosclerotic disease. The frequent occurrence of the two diseases in the same individual doubles the risk of cardiovascular death, as well as substantially increasing the frequency of transient ischemic attacks, strokes, peripheral vascular disease with lower extremity amputations, as well as end-stage renal disease and blindness. Although hypertension usually occurs in IDDM in association with renal disease, in NIDDM the evolution of hypertension appears to be multifactorial and independent of renal disease. Obesity appears to be dissociable from hypertension and NIDDM with a common link between obesity, hypertension and NIDDM appearing to be hyperinsulinism and insulin resistance. It has been suggested that hyperinsulinism and insulin resistance may lead to hypertension through altered intracellular calcium metabolism, enhanced renal sodium reabsorption, or through an effect of insulin upon lipid and/or catecholamine metabolism. Further, insulin itself may have a direct effect upon the atherosclerotic process in the hypertensive diabetic patient. These considerations have been taken into account in the structuring of antihypertensive therapy in Type I and Type II Diabetes Mellitus.

Non-insulin-dependent diabetes mellitus (NIDDM) is characterized by insulin resistance and beta-cell dysfunction. This review focuses on the beta-cell, what defects occur when and why. Two major anatomic observations have been made in NIDDM. The beta-cell mass is mildly reduced, especially when obesity is taken into account. Also, amyloid deposits are frequently observed in the islets. It is unclear whether these changes are genetically mediated or result secondary to the loss of glucose homeostasis. Many studies have looked at some aspect of insulin secretion in NIDDM, and two types of distinct abnormalities have been described. Early on, there is a marked disruption in pulsatile insulin delivery, which is potentially an important contributor to the insulin resistance. It is unclear whether the loss of pulsatile delivery is acquired or genetically induced. Later, after glucose intolerance has started, several other secretory abnormalities develop coincident with loss of beta-cell glucorecognition. The net result is further deterioration in timing of insulin delivery and postprandial hyperglycemia. A second important consequence of the glucose blindness is that the inherent compensatory beta-cell mechanisms that guard against hyperglycemia are bypassed. We propose that the loss of glucose responsiveness is a direct result of an elevated glucose concentration (so-called glucotoxicity) and have generated substantial data in rat models that support this idea. The logical conclusion is that beta-cell function in NIDDM can be maximized by achieving the best metabolic control possible.

Diabetes mellitus is the second most prevalent chronic disease in children in the U.S. It is associated with severe manifestations which include blindness and circulation deficiencies as well as markedly increased risk of death. The etiology of diabetes mellitus remains a mystery although both genetic and environmental factors have been implicated. The geneticist is confronted with a number of obstacles in his attempts to unravel this problem, including differences in the definition of affected individuals. This matter was certainly clarified by the separation of noninsulin-dependent diabetes (NIDDM) and insulin-dependent diabetes mellitus (IDDM) into two separate disease entities. Twin studies, however, show that IDDM cannot be entirely due to genetic causes as concordance is no more than about 50%. Although the disease is then clearly not inherited per se, the "susceptibility" to diabetes seems almost surely inherited and, provided this susceptibility, the disease can be brought on by environmental factors. Until the underlying mechanism causing IDDM is completely ascertained, we have to rely on genetic markers to approach the study of the inheritance thereof. Since, in the early 1970s, research by Nerup's and Cudworth's groups revealed associations between the HLA-B locus and IDDM, the HLA markers are considered the classical genetic markers for IDDM susceptibility. In this paper, we review the nature of the genetic susceptibility to IDDM and the possible environmental factors which can bring on the disease.

From a telephone survey of the health status of a random sample of the general population of Utah, we identified 255 people with adult onset diabetes. We compared them to 622 non-diabetic controls, matched for age, sex, and urban/rural country of residence. We examined diabetes as a risk factor for heart diseases, stroke, and blindness and its interaction with other known risk factors. Diabetes interacted with smoking history so as to increase the risk of stroke, heart disease, and blindness. Diabetes also interacted with hypertension in their effect on the prevalence of blindness and, to a small extent, heart disease. Among the diabetics, duration of diabetes was associated with macrovascular and microvascular complications developing after the diagnosis of diabetes. Those with longer duration of disease showed an increase in risk for microvascular (kidney disease, blindness) and macrovascular (heart disease, stroke, amputations) complications. Although the estimates were imprecise, the effect of duration on macrovascular complications was greater among diabetics with a history of hypertension; the effect on microvascular complications was greater among smokers. The findings are compared to previous studies and the utility of diabetes prevalence data is discussed.

Among the 1135 Rochester residents discovered to have diabetes in the period 1945-69, the prevalence of retinopathy was 2.6% at the time of initial diagnosis. Among those free of retinopathy at diagnosis of diabetes, the subsequent incidence of any retinopathy was 17.4 per 1000 person-years and for proliferative retinopathy alone was 1.6 per 1000 person-years, based on 12,000 person-years of follow-up. The incidence rate of retinopathy was almost three times greater among residents with insulin-dependent (IDDM) than with non-insulin-dependent diabetes (NIDDM); however, the actual number of retinopathy cases was over four times greater among the more numerous residents with NIDDM. By 20 yr after diagnosis of diabetes, the cumulative incidence of retinopathy approached 70% among IDDM subjects and was 30% and 36%, respectively, among the obese and nonobese NIDDM residents. The epidemiologic patterns for proliferative retinopathy were qualitatively similar to those for nonproliferative retinopathy. The risk of blindness was greater among those with proliferative than with nonproliferative retinopathy but was substantial even for those without retinopathy. Most blindness was caused by factors other than isolated diabetic retinopathy.

In November 1990, we carried out a survey of chronic complications of diabetes in more than 2000 diabetic patients who were seen on one day in 35 medical institutions including university hospitals, other hospitals and small clinics. More than 60% were aged 55-74 years. About 7% of patients had IDDM. Hypertension was present in 38.5%. Proteinuria was positive in 20% and 1% of patients were on dialysis therapy. 28% had visual disturbance and 2.9% had blindness in one or both eyes. Retinopathy was observed in 38% and proliferative retinopathy in 10%. The prevalences of myocardial infarction, angina pectoris, cerebral infarction and foot ulcer and gangrene were 2.1%, 4.7%, 5.7% and 2%, respectively, including the histories of these complications. Amputation of lower extremities was seen in only 0.6%. Microangiopathies were generally more frequent and more severe in IDDM than NIDDM. The prevalence of microangiopathy was as common as, but macroangiopathy seems less frequent than, the figures given in 'Diabetes in America'.
