A case-control design was used to investigate the effects of preexisting chronic conditions on in-hospital mortality in adult trauma patients. Cases consisted of all trauma deaths (n = 3074) that occurred in 1983 in any of the 331 acute care hospitals in California. Three to four control patients (injured survivors) were matched to each case patient on the basis of injury severity, age, and individual hospital (n = 9869). The data source consisted of hospital discharge abstract data uniformly collected on all admissions to acute care hospitals in the state. Conditional logistic regression techniques were used to estimate the relative odds of dying for patients with and without one or more of 11 preexisting chronic conditions identified as potentially detrimental to outcome. The presence of cirrhosis (relative odds = 4.5), congenital coagulopathy (relative odds = 3.2), ischemic heart disease (relative odds = 1.8), chronic obstructive pulmonary disease (relative odds = 1.8), and diabetes (relative odds = 1.2) all significantly increased the risk of dying. These data provide statistical evidence to support the recommendation of the American College of Surgeons that the presence of underlying disease be considered in decisions to triage and transfer patients to trauma centers. They also underscore the importance of underlying disease in the case-mix adjustment of case-fatality rates and the identification of unexpected deaths for quality assurance review.

Although type II diabetes is associated with both microvascular and macrovascular complications, duration of diabetes and severity of glycemia are strongly associated only with the former. Since prediabetic individuals are hyperinsulinemia, and since hyperinsulinemia may be a cardiovascular risk factor, we hypothesized that prediabetic individuals might have an atherogenic pattern of risk factors even before the onset of clinical diabetes, thereby explaining the relative lack of an association of macrovascular complications with either glycemic severity or disease duration. We documented the cardiovascular risk factor status of 614 initially nondiabetic Mexican Americans who later participated in an 8-year follow-up of the San Antonio Heart Study, a population-based study of diabetes and cardiovascular disease. Individuals who were nondiabetic at the time of baseline examination, but who subsequently developed type II diabetes (ie, confirmed prediabetic subjects, n = 43), had higher levels of total and low-density lipoprotein cholesterol, triglyceride, fasting glucose and insulin, 2-hour glucose, body mass index, and blood pressure, and lower levels of high-density lipoprotein cholesterol than subjects who remained nondiabetic (n = 571). Most of these differences persisted after adjustment for obesity and/or level of glycemia, but were abolished after adjustment for fasting insulin concentration. When subjects with impaired glucose tolerance at baseline (n = 106) were eliminated, the more atherogenic pattern of cardiovascular risk factors was still evident (and statistically significant) among initially normoglycemic prediabetic subjects. These results indicate that prediabetic subjects have an atherogenic pattern of risk factors (possibly caused by obesity, hyperglycemia, and especially hyperinsulinemia), which may be present for many years and may contribute to the risk of macrovascular disease as much as the duration of clinical diabetes itself.

Recently, nicotinic acid has been recommended as a first-line hypolipidemic drug. To determine the effectiveness of nicotinic acid in dyslipidemic patients with non-insulin-dependent diabetes mellitus, 13 patients were treated in a randomized crossover trial. Patients received either nicotinic acid (1.5 g three times daily) or no therapy (control period) for 8 weeks each. Compared with the control period, nicotinic acid therapy reduced the plasma total cholesterol level by 24%, plasma triglyceride level by 45%, very-low-density lipoprotein cholesterol level by 58%, and low-density lipoprotein cholesterol level by 15%, and it increased the high-density lipoprotein cholesterol level by 34%. However, nicotinic acid therapy resulted in the deterioration of glycemic control, as evidenced by a 16% increase in mean plasma glucose concentrations, a 21% increase in glycosylated hemoglobin levels, and the induction of marked glycosuria in some patients. Furthermore, a consistent increase in plasma uric acid levels was observed. Therefore, despite improvement in lipid and lipoprotein concentrations, because of worsening hyperglycemia and the development of hyperuricemia, nicotinic acid must be used with caution in patients with non-insulin-dependent diabetes mellitus with dyslipidemia. We suggest that the drug not be used as a first-line hypolipidemic drug in patients with non-insulin-dependent diabetes mellitus.

Although national data have consistently shown an increased risk of death from stroke among blacks, few studies have addressed the reasons for this excess mortality. We compared the incidence of stroke among 1298 blacks and 7814 whites, aged 35 to 74 years, in the 10-year follow-up of the respondents from the First National Health and Nutrition Survey. Blacks had a higher estimated incidence of stroke than whites even after adjustment for age, hypertension, and diabetes mellitus; the relative risk was 1.4 (95% confidence interval, 1.0 to 2.0) for black women and 1.1 (95% confidence interval, 0.8 to 1.6) for black men. The relative risks for stroke associated with hypertension and diabetes mellitus were unrelated to race. Although efforts to treat hypertension and diabetes are among the most important public health measures for reducing stroke, a more complete understanding of the determinants of stroke may be required to account for the excess stroke risk experienced by blacks.

Persons with diabetes experience elevated risks of a variety of other illnesses-- including circulatory, visual, neurological, renal, and skin disorders--relative to their nondiabetic peers. Previous estimates of the economic burden of diabetes, however, have not taken full account of this related morbidity and mortality and have therefore understated the cost to the nation due to this disease. Accordingly, we estimated the economic costs of type II, or non-insulin-dependent, diabetes mellitus, reflecting its contribution to the total burden of disease in the United States. In 1986, non-insulin-dependent diabetes mellitus was responsible for $11.6 billion in health care expenditures, including $6.8 billion for diabetic care and $4.8 billion attributable to an excess prevalence of related (principally cardiovascular) conditions. The human toll of non-insulin-dependent diabetes mellitus included 144,000 deaths -- about 6.8% of total US mortality -- and the total disability of 951,000 persons. The total economic burden of non-insulin-dependent diabetes mellitus in 1986, including health care expenditures and productivity forgone due to disability and premature mortality, was $19.8 billion.

During the last 18 years, considerable research has been conducted on the role of dietary fiber in health and disease. Interest was stimulated by epidemiologic studies that associated a low intake of dietary fiber with the incidence of colon cancer, heart disease, diabetes, and other diseases and disorders. Dietary fiber is not a single substance. There are significant differences in the physiological effects of the various components of dietary fiber. A Recommended Dietary Allowance for dietary fiber has not been established. However, an adequate amount of dietary fiber can be obtained by choosing several servings daily from a variety of fiber-rich foods such as whole-grain breads and cereals, fruits, vegetables, legumes, and nuts.

Cardiovascular disease is the leading cause of morbidity, disability, and death among patients with type II (non-insulin-dependent) diabetes mellitus. Moreover, hyperlipidemia is also common among these patients. Despite this, there are virtually no data regarding the level of awareness and treatment of hyperlipidemia among diabetic subjects at the community level. We therefore examined 374 Mexican-Americans and 86 non-Hispanic whites with type II diabetes identified in an epidemiologic survey that involved 3279 Mexican-Americans and 1847 non-Hispanic whites who resided in San Antonio, Tex. More than 40% of the diabetic subjects were hyperlipidemic according to the criteria of the National Cholesterol Education Program, and an additional 23% had hypertriglyceridemia and/or low levels of high-density lipoprotein cholesterol. By contrast, less than one fourth of the nondiabetic subjects were hyperlipidemic. Only approximately 25% of non-Hispanic whites with diabetes were aware of their hyperlipidemia, and less than 10% were receiving treatment. Awareness and treatment were even less frequent among Mexican-Americans with diabetes. Community physicians should be encouraged to give early attention to the management of lipid disorders in their diabetic patients.

We describe the functioning and well-being of patients with depression, relative to patients with chronic medical conditions or no chronic conditions. Data are from 11,242 outpatients in three health care provision systems in three US sites. Patients with either current depressive disorder or depressive symptoms in the absence of disorder tended to have worse physical, social, and role functioning, worse perceived current health, and greater bodily pain than did patients with no chronic conditions. The poor functioning uniquely associated with depressive symptoms, with or without depressive disorder, was comparable with or worse than that uniquely associated with eight major chronic medical conditions. For example, the unique association of days in bed with depressive symptoms was significantly greater than the comparable association with hypertension, diabetes, and arthritis. Depression and chronic medical conditions had unique and additive effects on patient functioning.

The Medical Outcomes Study was designed to (1) determine whether variations in patient outcomes are explained by differences in system of care, clinician specialty, and clinicians' technical and interpersonal styles and (2) develop more practical tools for the routine monitoring of patient outcomes in medical practice. Outcomes included clinical end points; physical, social, and role functioning in everyday living; patients' perceptions of their general health and well-being; and satisfaction with treatment. Populations of clinicians (n = 523) were randomly sampled from different health care settings in Boston, Mass; Chicago, Ill; and Los Angeles, Calif. In the cross-sectional study, adult patients (n = 22,462) evaluated their health status and treatment. A sample of these patients (n = 2349) with diabetes, hypertension, coronary heart disease, and/or depression were selected for the longitudinal study. Their hospitalizations and other treatments were monitored and they periodically reported outcomes of care. At the beginning and end of the longitudinal study, Medical Outcomes Study staff performed physical examinations and laboratory tests. Results will be reported serially, primarily in The Journal.

To determine whether the higher prevalence of diabetes found among blacks in the United States is explained by racial differences in obesity, we examined the prevalence of diabetes adjusted for adiposity, education, and income in a cohort of US Army veterans from the Vietnam era. Among 12,558 white men and 1677 black men, aged 30 to 47 years, blacks were more likely than whites to have diagnosed diabetes (adjusted prevalence ratio, 1.9; 95% confidence interval, 1.3 to 2.7). Within every age, adiposity, and socioeconomic stratum, blacks had a higher prevalence of diagnosed diabetes than whites. In a subgroup of veterans for whom fasting serum glucose values were measured, blacks were more likely than whites to have fasting hyperglycemia (fasting serum glucose value greater than or equal to 7.8 mmol/L) (adjusted prevalence ratio, 5.7; 95% confidence interval, 2.7 to 12.0). These data provide evidence that the higher prevalence of diabetes found among blacks is not explained by differences in obesity.
