Trends in nonfatal coronary heart disease in the United States, 1980 through 1989.

BACKGROUND: Although coronary heart disease mortality has been decreasing, little is known about trends in morbidity from coronary heart disease. We evaluated trends in nonfatal coronary heart disease in the United States during 1980 through 1989. METHODS: We analyzed data from the National Health Interview Survey, an ongoing survey of representative samples of the civilian, noninstitutionalized population of the United States. Survey respondents were determined to have coronary heart disease if they reported ever having a myocardial infarction or heart attack, angina pectoris, or coronary heart disease. Incidence was defined as initial onset of a coronary heart disease condition during the year preceding the interview date. RESULTS: About 6 million people were estimated to be living with coronary heart disease. The age-standardized prevalence was relatively constant at about 25 per 1000. Among white men, however, prevalence increased significantly over the 10-year period. Among 75- to 84-year-old men, prevalence increased from 100 per 1000 in 1980 to 179 per 1000 in 1989. Among men and women 45 to 54 years old, prevalence decreased. Overall, the incidence rate of nonfatal coronary heart disease was relatively flat (at about 3 per 1000 per year after 1983). Among white women, the incidence rate increased from 1.4 to 2.8 per 1000, and by the end of the decade it nearly equaled the incidence rate among white men. CONCLUSIONS: Overall, the burden of nonfatal coronary heart disease remained fairly constant during the 1980s. The trends, however, were not uniform in all population groups. The apparent increasing incidence among women deserves continued monitoring. An encouraging trend is the decreasing prevalence in the younger age groups.

The 10-year incidence of overweight and major weight gain in US adults.

We estimated the 10-year incidence of major weight gain (a gain in body mass index of greater than or equal to 5 kg/m2 and overweight (a body mass index of greater than or equal to 27.8 for men and greater than or equal to 27.3 for women) in US adults using data from the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study. Persons aged 25 to 74 years at baseline were reweighed a decade after their initial examination (men, 3727; women, 6135). The incidence of major weight gain was twice as high in women and was highest in persons aged 25 to 34 years (men, 3.9%; women, 8.4%). Initially overweight women aged 25 to 44 years had the highest incidence of major weight gain of any subgroup (14.2%). For person not overweight at baseline (men, 2760; women, 4295), the incidence of becoming overweight was similar in both sexes and was highest in those aged 35 to 44 years (men, 16.3%; women, 13.5%). We conclude that obesity prevention should begin among adults in their early 20s and that special emphasis is needed for young women who are already overweight.

Smoking and the risk of peptic ulcer disease among women in the United States.

Although multiple studies support a causal relationship between smoking and peptic ulcers in men, data for women are limited. Therefore, we used data from the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study, a nationally representative prospective study of US adults, to evaluate the impact of smoking on the incidence of peptic ulcers in women. The study cohort included 2851 women who had not been diagnosed as having a peptic ulcer prior to the baseline interview. Among these women, 140 (4.9%) developed peptic ulcer disease. During 12.5 years of follow-up, the estimated cumulative incidence of ulcers was 10.0% for current smokers, 6.4% for former smokers, and 5.4% for never smokers. After adjusting for age, education, regular aspirin use, coffee consumption, and use of alcohol, current smokers were 1.8 times more likely to develop ulcers than never smokers (95% confidence interval, 1.2 to 2.6); the risk of peptic ulcer increased as the amount smoked increased. During the time of this study, we estimate that approximately 20% of incident peptic ulcer cases among US women were attributable to cigarette smoking.

Race and sex differences in rates of invasive cardiac procedures in US hospitals. Data from the National Hospital Discharge Survey.

BACKGROUND: Lower rates of invasive cardiac procedures have been reported for blacks and women than for white men. However, few studies have adjusted for differences in the type of hospital of admission, insurance status, and disease severity. SETTING, DESIGN, AND PARTICIPANTS: Data from the National Hospital Discharge Survey were used to investigate race and sex differences in rates of cardiac catheterization, percutaneous transluminal coronary angioplasty, and coronary artery bypass surgery among 10,348 persons hospitalized for acute myocardial infarction. RESULTS: White men consistently had the highest procedure rates, followed by white women, black men, and black women. After matching for the hospital of admission and adjusting for age, in-hospital mortality, health insurance, and hospital transfer rates (with white men as the referent), the odds ratios for cardiac catheterization were 0.67 (95% confidence interval [CI], 0.51 to 0.87) for black men, 0.72 (95% CI, 0.63 to 0.83) for white women, and 0.50 (95% CI, 0.37 to 0.68) for black women. Similar race-sex differences were noted for percutaneous transluminal coronary angioplasty and coronary artery bypass surgery. CONCLUSIONS: Race and sex differentials in the rates of invasive cardiac procedures remained despite matching for the hospital of admission and controlling for other factors that influence procedure rates, suggesting that the race and sex of the patient influence the use of these procedures.

Self-perceived stress and the risk of peptic ulcer disease. A longitudinal study of US adults.

BACKGROUND: Although many physicians and laypersons believe that stress plays a role in the occurrence of peptic ulcer disease, the importance of stress in the pathogenesis of peptic ulcers remains controversial. METHODS: To investigate the relationship between perceived stress and peptic ulcer disease we used data from the National Health and Nutrition Examination Survey Epidemiologic Follow-up Study--a nationally representative cohort study of US adults. This analysis included 4511 persons who had not previously been diagnosed with peptic ulcer disease. RESULTS: At baseline, 68% of the cohort perceived themselves as stressed. During 13 years of follow-up, 208 persons developed ulcers; the cumulative incidence of ulcers was 7.2% for persons who were stressed and 4.0% for persons who were not. After we adjusted for age, sex, education, smoking status, and regular aspirin use, persons who perceived themselves as stressed were 1.8 times more likely to develop ulcers than those who did not (95% confidence interval, 1.3 to 2.5). We also found a graded relationship between the perceived amount of stress and the incidence of peptic ulcers; relative to nonstressed persons, the relative risk of developing an ulcer was 1.4, 1.9, 2.3, 2.4, and 2.9 at five increasing levels of stress. CONCLUSIONS: These findings suggest that persons who perceive their lives as stressful may be at increased risk for the development of peptic ulcer disease.

Leisure-time physical activity among older adults. United States, 1990.

OBJECTIVE: To investigate the prevalence and selected correlates of leisure-time physical activity in a nationally representative sample of persons aged 65 years or older. METHODS: Data from 2783 older male and 5018 older female respondents to the 1990 National Health Interview Survey were used. Regular physical activity was defined as participation in leisure-time physical activities 3 times or more per week for 30 minutes or more during the previous 2 weeks. Odds ratios (ORs) were estimated from multivariate logistic regression analysis. RESULTS: Prevalence of regular physical activity was 37% among older men and 24% among older women. Correlates of regular physical activity included the perception of excellent to good health (men: OR, 1.5; 95% confidence interval [CI], 1.1-1.9; women: OR, 1.6; 95% CI, 1.3-1.9), correct exercise knowledge (men: OR, 2.4; 95% CI, 1.9-3.1; women: OR, 2.7; 95% CI, 2.2-3.4), no activity limitations (men: OR, 1.3; 95% CI, 1.0-1.6; women: OR, 1.7; 95% CI, 1.4-2.0) and not perceiving "a lot" of stress during the previous 2 weeks (men: OR, 1.7; 95% CI, 1.2-2.4; women: OR, 1.3; 95% CI, 1.0-1.6). Among those who had been told at least twice that they had high blood pressure, physician's advice to exercise was associated with regular physical activity (men: OR, 1.6; 95% CI, 1.2-2.3; women: OR, 1.5; 95% CI, 1.2-1.9). The 2 major activities among active older adults were walking (men, 69%; women, 75%) and gardening (men, 45%; women, 35%). CONCLUSIONS: Prevalence of regular physical activity is low among older Americans. Identifying the correlates of physical activity will help to formulate strategies to increase physical activity in this age group.

Heart failure survival among older adults in the United States: a poor prognosis for an emerging epidemic in the Medicare population.

OBJECTIVE: To describe the 6-year probability of survival for older adults after their first hospitalization for heart failure. SETTING: National Medicare hospital claims records for 1984 through 1986 and Medicare enrollment records from 1986 through 1992. DESIGN: We identified a national cohort of 170 239 (9% black patients) Medicare patients, 67 years or older, with no evidence of heart failure in 1984 or 1985, who were hospitalized and discharged for the first time in 1986 with a principal diagnosis of heart failure. For groups defined by race, sex, age, Medicaid eligibility, and comorbid conditions, we compared the probability of survival with Cox proportional hazards regression. RESULTS: Only 19% of black men, 16% of white men, 25% of black women, and 23% of white women survived 6 years. One third died within the first year. Men had lower median survival and 38% greater risk of mortality than did women (P<.05). White men had 10% greater risk of mortality than did black men (P<.05). Medicaid eligibility (white adults only) and diabetes were associated with increased mortality (P<.05). CONCLUSIONS: The prognosis for older adults with heart failure underscores the importance of prevention strategies and early detection and treatment modalities that can prevent, improve, or reverse myocardial dysfunction, particularly for the growing number of adults who are at increased risk for developing heart failure because of hypertension, diabetes, or myocardial infarction.

Serum folate and risk for coronary heart disease: results from a cohort of US adults.

PURPOSE: To assess the role of serum folate in the risk for coronary heart disease in a national cohort of US adults. METHODS: Data from the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study (N = 1921) were used to determine whether a low serum folate concentration was associated with an increased risk for incident coronary heart disease (N = 284). The Cox proportional hazards model adjusted for age, sex, race, education, serum cholesterol, systolic blood pressure, body mass index, cigarette smoking, and alcohol consumption. RESULTS: The association between folate and risk for coronary heart disease differed by age group (p = 0.03). Among persons aged 35-55 years, the relative risk for heart disease was 2.4 (95% confidence interval (CI), 1.1-5.2) for persons in the lowest quartile (< or = 9.9 nmol/L) when compared with those in the highest quartile (> or = 21.8 nmol/L). However, among persons > or = 55 years the relative risk was 0.5 (95% CI, 0.3-0.8) for comparisons of the lowest versus highest quartiles. CONCLUSIONS: If the age differences in the risk for heart disease are confirmed, randomized clinical trials assessing the role of folic acid for the prevention of heart disease may need to include young adults in order to demonstrate benefits related to folate supplementation.

Risk factors for coronary heart disease mortality among persons with diabetes.

Although coronary heart disease is a leading cause of morbidity and mortality among persons with diabetes, the risk factors for coronary heart disease have not been well established for this population. The authors performed a case-control analysis by using data from two large population-based surveys. Cases of persons who died of coronary heart disease were identified from the 1986 National Mortality Followback Survey, and controls were taken from behavioral risk factor surveys conducted in 35 states in 1988. Diabetic women younger than 55 years with no other risk factors for coronary heart disease had a 16-fold higher risk of dying from coronary heart disease than did women without diabetes. About one-third of younger women who died of coronary heart disease had diabetes. Diabetic men less than 45 years old with no other risk factors for coronary heart disease had an eightfold higher risk of coronary heart disease mortality. Among older white men and women, diabetes increased the risk of mortality from coronary heart disease about twofold. In younger diabetics, current cigarette smoking was associated with a 50% increase in risk, and high blood pressure increased the risk more than threefold. In the older age group, risk factors for coronary heart disease mortality were similar among those with and those without diabetes: Cigarette smoking and high blood pressure each were associated with about a twofold increase in risk. Diabetes is a particularly strong risk factor for mortality from coronary heart disease in young adults. Smoking and blood pressure control represent major opportunities to reduce the risk of coronary heart disease among persons with diabetes.

National trends in the initial hospitalization for heart failure.

OBJECTIVES: Heart failure is a major health care burden among older adults, but information on recent trends has not been available. We compare rates, sociodemographic characteristics, and discharge outcomes of the initial hospitalization for heart failure in the Medicare populations of 1986 and 1993. DESIGN: Information reported on the Medicare hospital claims record during initial hospitalization for heart failure was compared for patients aged 65 and older hospitalized in 1986 (N = 631,306) and those aged 65 and older hospitalized in 1993 (N = 803,506). RESULTS: Age-standardized hospitalization rates (per 1000 person-years) for any diagnosis of heart failure were higher in 1993 than in 1986 (white: 24.6 vs 22.4, black: 26.1 vs 22.4, respectively). Age-specific results suggested an earlier onset of heart failure in black adults. In 1993, compared with 1986, higher proportions of heart failure patients were discharged to another care facility (white: 23.9% vs 16.8%, black: 17.6% vs 10.5%, respectively) or to health service care at home (white: 11.3% vs 6.0%, black: 12.4% vs 6.5%, respectively). In contrast, in-hospital mortality was lower in 1993 than in 1986 (white: 10.4% vs 13.3%, black: 8.9% vs 11.1%, respectively). CONCLUSION: The increased numbers of hospitalizations for heart failure and the likelihood that these patients will require advanced nursing care after discharge have important implications for future national health care expenditures and resources.

Hepatitis B vaccination programs for hospital workers: results of a statewide survey.

To assess the implementation of hepatitis B virus (HBV) vaccination programs for hospital workers, we mailed questionnaires to all 229 licensed Michigan hospitals. The response rate was 96% (221/229); of these, 68% (150/221) had vaccination programs. Although multiple hospital characteristics were associated with the presence of a vaccination program, characteristics that independently predicted the presence of a program were medical school affiliation, nonpsychiatric specialty, and the existence of a hepatitis B immune globulin protocol. The most common reason given (56%, 40/71) for the absence of a program was insufficient worker risk of hepatitis B infection; this response was frequent in psychiatric (91%, 10/11) and rural hospitals (61%, 11/18). Among high-risk workers, attending physicians were less likely than other high-risk workers to be included in vaccination programs (68% vs. 95%, respectively). Fear of vaccine-associated acquired immunodeficiency syndrome was most frequently cited as the primary reason for vaccine refusal. We conclude that unwarranted fears about the vaccine's safety need to be dispelled, that high-risk physicians should be included in vaccination programs, and that rural and psychiatric hospital policies reflect their perceived risk of occupational HBV infection.

Socioeconomic status, race, and death from coronary heart disease.

INTRODUCTION: Data to assess factors associated with differences in coronary heart disease mortality between Caucasians and African Americans are limited. We assessed risks for sudden, nonsudden, and other coronary death between Caucasians and African Americans in relation to known risk factors for coronary disease and socioeconomic status. METHODS: We analyzed data from the 1986 National Mortality Followback Survey, the 1985 National Health Interview Survey, and the U.S. Bureau of the Census. Logistic regression methods were used to create multivariate models to assess the relationship of socioeconomic status and other known modifiable risk factors to death from each of the three coronary diseases for Caucasians and African Americans separately. RESULTS: In an age- and gender-adjusted analysis of data on men 25-44 years old and women 25-54 years old, African Americans had about twice the risk for sudden, nonsudden, or other coronary death as did Caucasians. Adjusted risks for coronary death for Caucasians associated with modifiable risk factors (cigarette smoking, body weight, diabetes, and hypertension) either resembled or were slightly greater than those for African Americans. Half or more of all excess risks for African Americans in multivariate models could be explained by socioeconomic status. About 18% of excess sudden coronary death risk could be further explained by known modifiable coronary heart disease risk factors. CONCLUSIONS: Broad public health efforts are needed to address these causes of excess mortality.

Screening mammography for women 50 years of age and older: practices and trends, 1987.

Recently, public and private efforts have been mounted to promote screening mammography. To assess recent trends in the percentage of women 50 years of age and older who have had a screening mammogram, we analyzed data from interviews from women from 33 states who participated in the 1987 Behavioral Risk Factor Surveillance System. Our study group included 8,402 women 50 years of age and older who had visited a physician for a routine checkup in the last year; among these 8,402 women, only 29% reported having had a screening mammogram in the past year. However, of the women in the study group, the percentage who had a screening mammogram in the last year showed a relative increase of 38% during 1987, from 24% for women interviewed in the first quarter of 1987 to 33% for women interviewed in the fourth quarter. However, not all groups of patients benefited equally from the observed trend--the absolute and relative increases in the percentage of women screened were lowest for women who were older, less educated, in low-income groups, and who had poor personal health practices. Although the percentage of women 50 years of age and older who reported being screened increased dramatically during 1987, special efforts are needed to reach the patient groups that are being left behind in the trend toward increased use of screening mammograms.

Patterns of self-reported drinking and driving in Michigan.

We analyzed a statewide telephone survey of Michigan adults to determine patterns of self-reported drinking and driving. The estimated prevalence of drinking and driving was 13.5 percent for men and 2.9 percent for women; the highest prevalence was among 18- to 24-year-old men (32 percent). Based on these estimates, over half a million Michigan adults drank and drove on over one million occasions during the month preceding the survey. Most drinking drivers (93 percent) reported binge drinking, yet 70 percent of them otherwise reported only moderate routine alcohol consumption, that is, they consumed fewer than 14 drinks a week on average. Because we were concerned about the validity of self-reports, we compared the patterns of self-reported alcohol use with the patterns of alcohol-related motor vehicle crashes. The pattern of self-reported drinking and driving (using age-, sex-, and region-specific estimates) was highly correlated with the pattern of injury in alcohol-related crashes (r = .96; p less than .0001). Self-reported patterns of alcohol use may be used to identify persons at highest risk for being injured or dying in a motor vehicle crash.

Relationship of childhood abuse and household dysfunction to many of the leading causes of death in adults. The Adverse Childhood Experiences (ACE) Study.

BACKGROUND: The relationship of health risk behavior and disease in adulthood to the breadth of exposure to childhood emotional, physical, or sexual abuse, and household dysfunction during childhood has not previously been described. METHODS: A questionnaire about adverse childhood experiences was mailed to 13,494 adults who had completed a standardized medical evaluation at a large HMO; 9,508 (70.5%) responded. Seven categories of adverse childhood experiences were studied: psychological, physical, or sexual abuse; violence against mother; or living with household members who were substance abusers, mentally ill or suicidal, or ever imprisoned. The number of categories of these adverse childhood experiences was then compared to measures of adult risk behavior, health status, and disease. Logistic regression was used to adjust for effects of demographic factors on the association between the cumulative number of categories of childhood exposures (range: 0-7) and risk factors for the leading causes of death in adult life. RESULTS: More than half of respondents reported at least one, and one-fourth reported > or = 2 categories of childhood exposures. We found a graded relationship between the number of categories of childhood exposure and each of the adult health risk behaviors and diseases that were studied (P < .001). Persons who had experienced four or more categories of childhood exposure, compared to those who had experienced none, had 4- to 12-fold increased health risks for alcoholism, drug abuse, depression, and suicide attempt; a 2- to 4-fold increase in smoking, poor self-rated health, > or = 50 sexual intercourse partners, and sexually transmitted disease; and 1.4- to 1.6-fold increase in physical inactivity and severe obesity. The number of categories of adverse childhood exposures showed a graded relationship to the presence of adult diseases including ischemic heart disease, cancer, chronic lung disease, skeletal fractures, and liver disease. The seven categories of adverse childhood experiences were strongly interrelated and persons with multiple categories of childhood exposure were likely to have multiple health risk factors later in life. CONCLUSIONS: We found a strong graded relationship between the breadth of exposure to abuse or household dysfunction during childhood and multiple risk factors for several of the leading causes of death in adults.

Depression and smoking initiation among US Latinos.

We assessed the relationship between depression and smoking initiation among people of Mexican, Puerto Rican and Cuban ancestry residing in specific geographic areas of the United States. Survey data were examined to calculate incidence of smoking initiation and prevalences and odds ratios for ever smoking by presence of depressed mood, a history of major depression or both conditions. Depressed mood, a history of major depression or both conditions were associated with smoking initiation risks during childhood, adolescence and young adulthood. These findings suggest that the relationship between depressive states and smoking initiation is established early in life. More definitive studies are needed to confirm these findings.

Dietary and weight control practices among persons with hypertension: findings from the 1986 Behavioral Risk Factor Surveys.

The National Heart, Lung, and Blood Institute has concluded that reducing sodium intake, controlling weight, and moderating alcohol consumption can help patients with hypertension control their blood pressure. To determine whether such patients have adopted recommended dietary practices, we analyzed data collected in 1986 from telephone surveys of adults in 26 states (no. = 34,395). The self-reported dietary practices that we evaluated were: use of table salt, alcohol consumption, and weight control practices. In comparison with persons who did not have hypertension (no. = 26,848), those with hypertension who were receiving pharmacological therapy ("treated hypertensives," no. = 5,025) were more likely to report limiting their use of table salt (odds ratio [OR] = 2.5) and were less likely to have their weight controlled (OR = 0.4). Although overweight persons with hypertension were more likely than persons with normal blood pressure to attempt to lose weight, most have not included exercise in their weight loss efforts. There was no difference between persons who do not have hypertension and treated patients with hypertension in their use of alcohol. Untreated persons with hypertension (no. = 2,378) were less likely to limit their use of table salt and less likely to moderate their use of alcohol than treated persons with hypertension but otherwise reported similar dietary practices. Dietetic practitioners may need to emphasize moderation of alcohol use and the use of physical activity to lose weight when counseling patients with hypertension.

Evaluation of smoking on the physical activity and depressive symptoms relationship.

Physical activity is inversely associated with depressive symptoms, and cigarette smoking is positively associated with depressive symptoms. Data from the first National Health and Nutrition Examination Survey (NHANES I) and the NHANES I Epidemiologic Follow-up study were analyzed to determine whether the relationship between physical activity and self-reported distress (depressive symptoms as measured by the Center for Epidemiologic Studies Depression Scale) was different for cigarette smokers and nonsmokers. Logistic regression was used to calculate odds ratios (adjusted for age, race, sex, education, alcohol use, and perceived health status) for depressive symptoms (> or = 16) associated with physical activity and smoking status among 2,054 respondents. At baseline, the odds ratio for depressive symptoms was about 2 times higher for moderately active smokers and nonsmokers, and 3 times higher for low active smokers and nonsmokers, compared with highly active nonsmokers. For 1,132 persons with a low number of depressive symptoms (< 16) at baseline, the incidence of depressive symptoms after 7-9 yr of follow-up was about 2 times higher for low/moderately active smokers and nonsmokers than for highly active nonsmokers. The association between physical activity and the prevalence and incidence of depressive symptoms is not significantly modified by smoking status.

Health promotion data for state health departments: telephone versus in-person survey estimates of smoking and alcohol use.

Abstract During 1988, more than 40 state health departments conducted telephone surveys to obtain state-specific population estimates of the prevalence of adult health behaviors and health practices. However, the comparability of estimates obtained from these telephone surveys with more expensive in-person surveys has not been assessed in an applied setting. This study compared the prevalence estimates of smoking and binge drinking obtained from a telephone survey (N = 1,492) with an in-person survey (N = 2,802) which were conducted by the state of Michigan during 1982-1983. Although the standard errors for the differences in the estimates for the two surveys were relatively large, the actual differences were consistently small within most age-, sex-, and education-specific groups. Despite certain limitations, telephone surveys provide a reasonable alternative to in-person surveys for estimating the prevalence of health behaviors. The data obtained from these surveys are being used to set state health objectives, to plan state-wide health promotion programs, and to support public health legislation.

Long-term secular trends in initiation of cigarette smoking among Hispanics in the United States.

Preventing the initiation of cigarette smoking plays a vital role in reducing rates of cigarette smoking. The authors investigated trends in cigarette smoking initiation among Mexican Americans, Cuban Americans, Puerto Rican Americans, compared with whites, by examining the cigarette smoking histories of adults from the 1982-83 Hispanic Health and Nutrition Examination Survey and the 1987 National Health Interview Survey. To evaluate these trends, they calculated the prevalence of cigarette smoking among 20-24-year-olds, an indicator of the rate of smoking initiation, in successive 5-year birth cohorts from 1908-12 to 1958-62 among Hispanics and from 1908-12 to 1963-67 among whites. Recently, rates of smoking initiation among Mexican American and Cuban American men have declined and converged with rates of initiation among white men. However, rates of initiation among Puerto Rican American men appeared to have remained unchanged since the 1950s. During the 1970s rates of smoking initiation among Cuban American and Puerto Rican American women surpassed those of white women. In the early 1980s, however, rates of initiation among these groups of Hispanic women have declined to levels comparable to or perhaps lower than the rates among white women. Although recently the rates among Mexican American women have been the lowest of all groups of women, they have not experienced appreciable declines. In general, rates of smoking initiation either declined or leveled off later for Hispanics than for whites. These results suggest that Hispanics tended to follow the smoking trends observed among whites and that special efforts are needed to prevent cigarette smoking among Hispanics.
