Dietary factors related to higher plasma fibrinogen levels of Japanese-americans in hawaii compared with Japanese in Japan.

OBJECTIVE: We investigated whether dietary factors explain higher plasma fibrinogen levels in Japanese emigrants living a Western lifestyle in Hawaii compared with Japanese in Japan. METHODS AND RESULTS: Plasma fibrinogen and nutrient intakes were examined by standardized methods in men and women 40 to 59 years of age from a Japanese-American sample in Hawaii (100 men and 106 women) and 4 population samples in Japan (569 men and 567 women). Multiple linear regression models were used to examine the relationship between dietary factors and the plasma fibrinogen difference between Hawaii and Japan. Average plasma fibrinogen was significantly higher in Hawaii compared with Japan (P<0.001 in both genders). In multiple linear regression analyses with each dietary variable considered separately, body mass index reduced the plasma fibrinogen difference between Hawaii and Japan by 20.4%; iron intake (mg/1000 kcal) and estimated total sugar intake (%kcal) reduced this difference by 30.0% and 14.4%, respectively. In a model that included body mass index, iron, estimated total sugars, and caffeine (also age and gender), this difference was reduced by 61.3% (from 42.2 to 16.3 mg/dL). CONCLUSIONS: Higher intake of iron, sugar, and caffeine, in addition to obesity, account largely for higher fibrinogen levels with Westernized lifestyle.

Assessment of analytical reproducibility of 1H NMR spectroscopy based metabonomics for large-scale epidemiological research: the INTERMAP Study.

Large-scale population phenotyping for molecular epidemiological studies is subject to all the usual criteria of analytical chemistry. As part of a major phenotyping investigation we have used high-resolution 1H NMR spectroscopy to characterize 24-h urine specimens obtained from population samples in Aito Town, Japan (n = 259), Chicago, IL (n = 315), and Guangxi, China (n = 278). We have investigated analytical reproducibility, urine specimen storage procedures, interinstrument variability, and split specimen detection. Our data show that the multivariate analytical reproducibility of the NMR screening platform was >98% and that most classification errors were due to urine specimen handling inhomogeneity. Differences in metabolite profiles were then assessed for Aito Town, Chicago, and Guangxi population samples; novel combinations of biomarkers were detected that separated the population samples. These cross-population differences in urinary metabolites could be related to genetic, dietary, and gut microbial factors.

Favorable cardiovascular risk profile (low risk) and 10-year stroke incidence in women and men: findings from 12 Italian population samples.

Recently, the focus of research on cardiovascular risk factors has broadened because of new data demonstrating benefits of low risk (i.e., favorable) levels of all major modifiable risk factors. Most data on low risk relate to coronary heart disease, not stroke. This population-based, 12-sample, Italian study (Progetto CUORE, 1983-2002), with 10-year follow-up, assessed the relation of low risk to stroke and implications for prevention. At baseline, women and men were 35-69 years of age. Only 3% were low risk; 80% were high risk. Overall, stroke incidence rates were 20.7 for men and 9.6 for women per 10,000 person-years. No strokes occurred in low risk participants, and stroke incidence was low with borderline elevation of only one risk factor. Four modifiable risk factors--elevated blood pressure, smoking, diabetes, and high total cholesterol/high density lipoprotein cholesterol ratio--related independently to stroke risk. For those at low risk or who had only one unfavorable (but not high) risk factor, the stroke rate was 76% lower than for high risk participants; for all persons not at high risk, the stroke rate was 57% lower than for those at high risk. Results show that favorable risk factor levels assure minimal stroke risk. Population-wide prevention is needed, especially improved lifestyles, to increase the prevalence of low risk.

Midlife body mass index and hospitalization and mortality in older age.

CONTEXT: Abundant evidence links overweight and obesity with impaired health. However, controversies persist as to whether overweight and obesity have additional impact on cardiovascular outcomes independent of their strong associations with established coronary risk factors, eg, high blood pressure and high cholesterol level. OBJECTIVE: To assess the relation of midlife body mass index with morbidity and mortality outcomes in older age among individuals without and with other major risk factors at baseline. DESIGN: Chicago Heart Association Detection Project in Industry study, a prospective study with baseline (1967-1973) cardiovascular risk classified as low risk (blood pressure < or =120/< or =80 mm Hg, serum total cholesterol level <200 mg/dL [5.2 mmol/L], and not currently smoking); moderate risk (nonsmoking and systolic blood pressure 121-139 mm Hg, diastolic blood pressure 81-89 mm Hg, and/or total cholesterol level 200-239 mg/dL [5.2-6.2 mmol/L]); or having any 1, any 2, or all 3 of the following risk factors: blood pressure > or =140/90 mm Hg, total cholesterol level > or =240 mg/dL (6.2 mmol/L), and current cigarette smoking. Body mass index was classified as normal weight (18.5-24.9), overweight (25.0-29.9), or obese (> or =30). Mean follow-up was 32 years. SETTING AND PARTICIPANTS: Participants were 17,643 men and women aged 31 through 64 years, recruited from Chicago-area companies or organizations and free of coronary heart disease (CHD), diabetes, or major electrocardiographic abnormalities at baseline. MAIN OUTCOME MEASURES: Hospitalization and mortality from CHD, cardiovascular disease, or diabetes, beginning at age 65 years. RESULTS: In multivariable analyses that included adjustment for systolic blood pressure and total cholesterol level, the odds ratio (95% confidence interval) for CHD death for obese participants compared with those of normal weight in the same risk category was 1.43 (0.33-6.25) for low risk and 2.07 (1.29-3.31) for moderate risk; for CHD hospitalization, the corresponding results were 4.25 (1.57-11.5) for low risk and 2.04 (1.29-3.24) for moderate risk. Results were similar for other risk groups and for cardiovascular disease, but stronger for diabetes (eg, low risk: 11.0 [2.21-54.5] for mortality and 7.84 [3.95-15.6] for hospitalization). CONCLUSION: For individuals with no cardiovascular risk factors as well as for those with 1 or more risk factors, those who are obese in middle age have a higher risk of hospitalization and mortality from CHD, cardiovascular disease, and diabetes in older age than those who are normal weight.

Association between protein intake and blood pressure: the INTERMAP Study.

BACKGROUND: Findings from epidemiological studies suggest an inverse relationship between individuals' protein intake and their blood pressure. METHODS: Cross-sectional epidemiological study of 4680 persons, aged 40 to 59 years, from 4 countries. Systolic and diastolic blood pressure was measured 8 times at 4 visits. Dietary intake based on 24-hour dietary recalls was recorded 4 times. Information on dietary supplements was noted. Two 24-hour urine samples were obtained per person. RESULTS: There was a significant inverse relationship between vegetable protein intake and blood pressure. After adjusting for confounders, blood pressure differences associated with higher vegetable protein intake of 2.8% kilocalories were -2.14 mm Hg systolic and -1.35 mm Hg diastolic (P<.001 for both); after further adjustment for height and weight, these differences were -1.11 mm Hg systolic (P<.01) and -0.71 mm Hg diastolic (P<.05). For animal protein intake, significant positive blood pressure differences did not persist after adjusting for height and weight. For total protein intake (which had a significant interaction with sex), there was no significant association with blood pressure in women, nor in men after adjusting for dietary confounders. There were significant differences in the amino acid content of the diets of persons with high vegetable and low animal protein intake vs the diets of persons with low vegetable and high animal protein intake. CONCLUSIONS: Vegetable protein intake was inversely related to blood pressure. This finding is consistent with recommendations that a diet high in vegetable products be part of healthy lifestyle for prevention of high blood pressure and related diseases.

Favorable cardiovascular risk profile and 10-year coronary heart disease incidence in women and men: results from the Progetto CUORE.

BACKGROUND: Cardiovascular risk factor research has recently broadened its focus based on new data indicating the benefits of low risk, i.e. favorable levels of all major risk factors. The aims of this study were to assess further the relation of low risk to coronary heart disease risk, and implications for prevention. DESIGN: We conducted a prospective population-based Italian study, of 7438 men and 13 009 women aged 35-69 years, with a mean follow-up of 10.4 years and validated first coronary events. METHODS: Baseline coronary heart disease risk was classified into three categories: low risk; unfavorable but not high risk; and high risk. To analyze the relation of these risk profiles to coronary heart disease incidence, age-adjusted, sex-averaged coronary heart disease incidence was calculated for persons free of coronary heart disease and stroke, stratified as baseline low risk, unfavorable but not high risk or high risk. To assess the independent relationship of individual risk factors to coronary heart disease incidence, multivariate proportional hazards models were computed for combinations of risk factors. RESULTS: Only 2.7% of participants met low risk criteria; 81.4% were high risk. Age-adjusted coronary heart disease incidence for the whole cohort was 37.1 out of 10000 person-years (men 59.0; women 15.3). No coronary heart disease events occurred in low-risk men, only two in low-risk women. For women and men who were not high risk, the age-sex standardized coronary heart disease rate was 62% lower than for high-risk participants. Blood pressure, need for antihypertensive medication, smoking, hyperglycemia, diabetes, total and high-density lipoprotein cholesterol were independently related to coronary heart disease risk. CONCLUSIONS: Favorable levels of all modifiable readily measured risk factors - rare among Italian adults - assure minimal coronary heart disease risk. Population-wide prevention is needed, especially improved lifestyles, to increase the proportion of the population at low risk.

Race/ethnicity, income, major risk factors, and cardiovascular disease mortality.

OBJECTIVES: We explored differences between Black and White men for cardiovascular disease (CVD) mortality across major risk factor levels. METHODS: Major CVD risk factors were measured among 300,647 White and 20,223 Black men aged 35 to 57 years who were screened for the Multiple Risk Factor Intervention Trial (MRFIT). Hazard ratios for CVD deaths for Black and White men over 25 years of follow-up were calculated for subgroups stratified according to risk factor levels. RESULTS: CVD was responsible for 2518 deaths among Black men and 30,772 deaths among White men. The age-adjusted Black-to-White CVD hazard ratio was 1.35 (95% confidence interval [CI]=1.29, 1.40); the risk- and income-adjusted ratio was 1.05 (95% CI=1.01, 1.10). CVD mortality rates were dramatically lower in cases of favorable risk profiles. However, fully adjusted Black-to-White CVD hazard ratios within groups at low, intermediate, high, and very high levels of overall risk were 1.76, 1.20, 1.10, and 0.94, respectively. Similar gradients were evident for individual risk factors. CONCLUSIONS: Higher CVD mortality rates among Black men were largely mediated by risk factors and income. These data underscore the need for sustained primordial risk factor prevention among Black men.

Cardiovascular risk profile earlier in life and Medicare costs in the last year of life.

BACKGROUND: Health care costs are generally highest in the year before death, and much attention has been directed toward reducing costs for end-of-life care. However, it is unknown whether cardiovascular risk profile earlier in life influences health care costs in the last year of life. This study addresses this question. METHODS: Prospective cohort of adults from the Chicago Heart Association Detection Project in Industry included 6582 participants (40% women), aged 33 to 64 years at baseline examination (1967-1973), who died at ages 66 to 99 years. Medicare billing records (1984-2002) were used to obtain cardiovascular disease-related and total charges (adjusted to year 2002 dollars) for inpatient and outpatient services during the last year of life. Participants were classified as having favorable levels of all major cardiovascular risk factors (low risk), that is, serum cholesterol level lower than 200 mg/dL (<5.2 mmol/L), blood pressure 120/80 mm Hg or lower and no antihypertensive medication, body mass index (calculated as weight in kilograms divided by the square of height in meters) lower than 25, no current smoking, no diabetes, and no electrocardiographic abnormalities, or unfavorable levels of any 1 only, any 2 only, any 3 only, or 4 or more of these risk factors. RESULTS: In the last year of life, average Medicare charges were lowest for low-risk persons. For example, cardiovascular disease-related and total charges were lower by 10,367 dollars and 15,318 dollars compared with those with 4 or more unfavorable risk factors; the fewer the unfavorable risk factors, the lower the Medicare charges (P for trends <.001). Analyses by sex showed similar patterns. CONCLUSION: Favorable cardiovascular risk profile earlier in life is associated with lower Medicare charges at the end of life.

Relation of long chain n-3 polyunsaturated fatty acid intake to serum high density lipoprotein cholesterol among Japanese men in Japan and Japanese-American men in Hawaii: the INTERLIPID study.

Epidemiologic evidence shows an inverse relationship between fish consumption and coronary heart disease (CHD) mortality. Associations between dietary intake of long chain n-3 polyunsaturated fatty acids (PUFA) and serum high density lipoprotein (HDL) cholesterol concentration are unknown. In this study, the association between n-3 PUFA (eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA)) intake and serum HDL cholesterol among Japanese men and women in Japan and Hawaii was examined. The study population consisted of Japanese ancestries from five research centers of the International Study of Macronutrients and Blood Pressure (INTERMAP) study, in Japan and Hawaii (672 men and 676 women), surveyed between 1996 and 1998. Four 24-h dietary recalls and one set of serum lipid measurements were performed. For men, n-3 PUFA intake and HDL cholesterol were higher in Japan than in Hawaii (n-3 PUFA: 1.32 g/day versus 0.47 g/day, p<0.001). For women, n-3 PUFA intake was higher in Japan than in Hawaii (p<0.001) but HDL cholesterol was not significantly different (p=0.752). After adjustment for age, body mass index, physical activity, number of cigarettes per day, alcohol intake, and hormone replacement therapy (for women), n-3 PUFA intake was positively associated with serum HDL cholesterol in men (4.6 mg/dl higher HDL cholesterol with 1%kcal higher n-3 PUFA intake, p=0.011). This association was not observed in women. This positive association of dietary n-3 PUFA with serum HDL cholesterol may partially explain the low mortality from CHD among Japanese men.

Association of dietary supplement use with specific micronutrient intakes among middle-aged American men and women: the INTERMAP Study.

OBJECTIVE: To assess dietary supplement use and its association with micronutrient intakes and adequacy among 2,195 US men and women aged 40 to 59 years from eight diverse population samples surveyed by the International Population Study on Macronutrients and Blood Pressure. DESIGN: Four 24-hour dietary recalls were collected, including information on dietary supplements. The Nutrition Data System (NDS) was used for nutrient analyses. Supplements not in NDS were classified separately (non-NDS). Intake of non-NDS supplements was documented. Participants were classified as not supplement users and supplement users, subclassified-due to concerns about nutritional value-as users of NDS supplements only (mostly vitamins and minerals) and users of non-NDS supplements (eg, botanicals, animal products, and enzymes). To assess effects of supplement use on micronutrient intake and adequacy, mean intakes from supplements, foods, and foods plus supplements were compared with Dietary Reference Intakes. PARTICIPANTS: Two thousand one hundred ninety-five US participants; 1,136 used supplements. STATISTICAL ANALYSES: Chi 2 tests, multivariate logistic regression, and means were used to assess differences in and factors related to supplement use and to determine dietary adequacy. RESULTS: Supplement use was more common among women, older participants, more educated participants, and Asian Americans. Body mass index and current cigarette smoking were significantly and inversely associated with supplement use; past smoking and education were significantly and positively associated with supplement use. Intake from foods plus supplements was considerably higher than from foods alone for vitamins A, C, and E; niacin; folate; and iron. CONCLUSIONS: Supplement use is common among middle-aged Americans and sizably increases daily intakes of several micronutrients. These data underscore the importance of dietary supplement assessment.

Relationship of fruit and vegetable consumption in middle-aged men to medicare expenditures in older age: the Chicago Western Electric Study.

BACKGROUND: High fruit and vegetable intake is associated with lower risk of hypertension, cardiovascular disease, and cancer. Little is known about the relationship of fruit and vegetable intake to health care expenditures. OBJECTIVE: Examine whether fruit and vegetable intake among middle-aged adults is related to Medicare charges-total, cardiovascular disease, cancer-related-in older age. DESIGN: Participants were grouped into one of three strata according to fruit and vegetable intake, determined from detailed dietary history (1958-1959): less than 14 cups per month, 14 to 42 cups per month, or more than 42 cups per month. Combined intake was classified as low, medium, or high. Medicare claims data (1984-2000) were used to estimate mean annual spending for eligible surviving participants (65 years and older) from the Chicago Western Electric Study: 1,063 men age 40 to 55 and without coronary heart disease, diabetes, and cancer at baseline (1957-1958). Cumulative charges before death (n = 401) were also calculated. RESULTS: Higher fruit and fruit plus vegetable intakes were associated with lower mean annual and cumulative Medicare charges (P values for trend .019 to .862). For example, with adjustment for baseline age, education, total energy intake, and multiple baseline risk factors, annual cardiovascular disease-related charges were 3,128 dollars vs 4,223 dollars for men with high vs low intake of fruit plus vegetables. Corresponding figures were 1,352 dollars vs 1,640 dollars for cancer-related charges and 10,024 dollars vs 12,211 dollars for total charges. Results were generally similar for vegetable intake. CONCLUSION: These findings, albeit mostly not statistically significant, suggest that for men high intake of fruits and fruits plus vegetables earlier in life has potential not only for better health status but also for lower health care costs in older age.

Relation of nutrient intake to microalbuminuria in nondiabetic middle-aged men and women: International Population Study on Macronutrients and Blood Pressure (INTERMAP).

BACKGROUND: Microalbuminuria (MA) is a risk factor for cardiovascular and renal disease. However, little is known about the relation of nutritional factors to MA, especially in individuals without diabetes. METHODS: Data collected by the International Population Study on Macronutrients and Blood Pressure from 1997 to 1999 were used to assess relations of multiple dietary factors (energy intake, macronutrients, and micronutrients) independent of lifestyle-related cardiovascular risk factors to MA (urinary albumin excretion, 30 to <300 mg/24 h). The study population included 4,381 Chinese, Japanese, UK, and US men and women without diabetes aged 40 to 59 years (17 population samples) without macroalbuminuria. RESULTS: MA prevalences ranged from 3.1% to 5.5% for men and 2.6% to 4.6% for women in the 4 countries. With adjustment for age and country, the following nutrients considered singly (of 29) were related in logistic regression analyses to MA prevalence ( P < 0.05): for men, inversely, iron, vitamin C and E, estimated total simple sugar, omega-6 fatty acid, polyunsaturated fatty acid, and calcium (all expressed as caloric density) intake; for women, directly, 24-hour urinary sodium excretion and alcohol intake. In multivariate analyses, sugar, iron, polyunsaturated fats, and vitamin C and E intake (in men) and alcohol intake (women only) remained associated with MA ( P < 0.05). MA also was related directly to body mass index ( P < 0.05), blood pressure ( P < 0.001), and smoking ( P > 0.05) and inversely to education ( P < 0.05 in women). CONCLUSION: In cross-sectional analyses, several nutrients were related to MA among men. Additional studies are required to confirm these findings.

Attainment of precision in implementation of 24 h dietary recalls: INTERMAP UK.

Collection of complete and accurate dietary intake data is necessary to investigate the association of nutrient intakes with disease outcomes. A standardised multiple-pass 24 h dietary recall method was used in the International Collaborative Study of Macro- and Micronutrients and Blood Pressure (INTERMAP) to obtain maximally objective data. Dietary interviewers were intensively trained and recalls taped, with consent, for randomly selected evaluations by the local site nutritionist (SN) and/or country nutritionists (CN) using a twelve-criterion checklist marked on a four-point scale (1, retrain, to 4, excellent). In the Belfast centre, seven dietary interviewers collected 932 24 h recalls from 40-59-year-old men and women. Total scores from the 134 evaluated recalls ranged from thirty-four to the maximum forty-eight points. All twelve aspects of the interviews were completed satisfactorily on average whether scored by the SN (n 53, range: probing 3.25 to privacy of interview 3.98) or CN (n 19, range: probing 3.26 to pace of interview and general manner of interviewer 3.95); the CN gave significantly lower scores than the SN for recalls evaluated by both nutritionists (n 31, Wilcoxon signed rank test, P=0.001). Five evaluations of three recalls identified areas requiring retraining or work to improve performance. Reporting accuracy was estimated using BMR; energy intake estimates less than 1.2 x BMR identifying under-reporting. Mean ratios in all age, sex and body-mass groups were above this cut-off point; overall, 26.1 % were below. Experiences from the INTERMAP Belfast centre indicate that difficulties in collection of dietary information can be anticipated and contained by the systematic use of methods to prevent, detect and correct errors.

Relation of body mass index in young adulthood and middle age to Medicare expenditures in older age.

CONTEXT: Increasing prevalence of overweight/obesity and rapid aging of the US population have raised concerns of increasing health care costs, with important implications for Medicare. However, little is known about the impact of body mass index (BMI) earlier in life on Medicare expenditures (cardiovascular disease [CVD]-related, diabetes-related, and total) in older age. OBJECTIVE: To examine relationships of BMI in young adulthood and middle age to subsequent health care expenditures at ages 65 years and older. DESIGN, SETTING, AND PARTICIPANTS: Medicare data (1984-2002) were linked with baseline data from the Chicago Heart Association Detection Project in Industry (CHA) (1967-1973) for 9978 men (mean age, 46.0 years) and 7623 women (mean age, 48.4 years) (baseline overall age range, 33 to 64 years) who were free of coronary heart disease, diabetes, and major electrocardiographic abnormalities, were not underweight (BMI <18.5), and were Medicare-eligible (> or =65 years) for at least 2 years during 1984-2002. Participants were classified by their baseline BMI as nonoverweight (BMI, 18.5-24.9), overweight (25.0-29.9), obese (30.0-34.9), and severely obese (> or =35.0). MAIN OUTCOME MEASURES: Cardiovascular disease-related, diabetes-related, and total average annual Medicare charges, and cumulative Medicare charges from age 65 years to death or to age 83 years. RESULTS: In multivariate analyses, average annual and cumulative Medicare charges (CVD-related, diabetes-related, and total) were significantly higher by higher baseline BMI for both men and women. Thus, with adjustment for baseline age, race, education, and smoking, total average annual charges for nonoverweight, overweight, obese, and severely obese women were, respectively, 6224 dollars, 7653 dollars, 9612 dollars, and 12,342 dollars (P<.001 for trend); corresponding total cumulative charges were 76, 866 dollars, 100,959 dollars, 125,470 dollars, and 174,752 dollars (P<.001 for trend). For nonoverweight, overweight, obese, and severely obese men, total average annual charges were, respectively, 7205 dollars, 8390 dollars, 10,128 dollars, and 13,674 dollars (P<.001 for trend). Corresponding total cumulative charges were 100,431 dollars, 109,098 dollars, 119,318 dollars, and 176,947 dollars (P<.001 for trend). CONCLUSION: Overweight/obesity in young adulthood and middle age has long-term adverse consequences for health care costs in older age.

Evaluation of measures of urinary albumin excretion in epidemiologic studies.

Twenty-four-hour urinary albumin excretion (UAE) is considered the gold standard for determining albumin level in epidemiologic studies, but this measure is inconvenient and often unavailable. Simpler alternatives include the albumin:creatinine ratio (ACR) and urinary albumin concentration (UAC) obtained from a single sample. The authors assessed the strengths and weaknesses of ACR and UAC as alternatives to UAE using albumin measurements from two 24-hour urine samples collected in 1996-1999 from 4,678 participants aged 40-59 years in the International Study of Macronutrients and Blood Pressure (17 population samples from four countries). The authors compared ACR and UAC with regard to correlations with UAE, daily within-person variability, and associations with known predictors of UAE. Rank-order correlations of ACR with UAE were 0.949 and 0.942 for men and women, respectively, versus 0.881 and 0.816 for UAC. Mean within-person coefficients of variation were 34.0-40.0% for the three measures, with the smallest values being observed for UAC. Average correlations with blood pressure were similar for UAE, ACR, and UAC, but the correlation with body mass index was lower for ACR (0.118 for ACR and 0.188 for UAC vs. 0.211 for UAE) because of high correlation between body mass index and creatinine level. Thus, UAC and ACR are acceptable alternatives to the more complex UAE, and the simpler UAC may be preferable to ACR in some respects.

Favorable cardiovascular risk profile in young women and long-term risk of cardiovascular and all-cause mortality.

CONTEXT: For women, impact of cardiovascular risk factors measured in young adulthood, particularly favorable (low-risk) profile, on mortality has been difficult to assess due to low short-term death rates. OBJECTIVE: To assess the relationship of baseline coronary risk factor status to mortality from coronary heart disease (CHD), cardiovascular diseases (CVDs), and all causes in young women. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: A total of 7302 women aged 18 to 39 years without prior CHD or major electrocardiographic abnormalities screened between 1967 and 1973 for the Chicago Heart Association Detection Project in Industry. Risk groups were defined using national guidelines for values of systolic and diastolic blood pressure, serum cholesterol level, body mass index, presence of diabetes, and smoking status. Participants were divided into 4 groups: low risk, 0 risk factors high but 1 or more unfavorable, 1 only risk factor high, and 2 or more risk factors high. MAIN OUTCOME MEASURES: All-cause mortality, CHD mortality, and CVD mortality; hazard ratio of outcome measures comparing low-risk group with other groups. RESULTS: Only 20% met low-risk criteria; 59% had high levels of 1 or more risk factors. During an average follow-up of 31 years, there were 47 CHD deaths, 94 CVD deaths, and 469 deaths from all causes. The age-adjusted CVD death rate per 10,000 person-years was lowest for low-risk women and increased with the number of risk factors, ie, 1.5, 1.7, 5.0, and 9.1 for low-risk; 0, 1, and 2 or more risk factors high, respectively. Multivariate-adjusted CVD mortality hazard ratio for low-risk women was 0.19 (95% confidence interval, 0.08-0.45) compared with women with 2 or more risk factors high. Similar patterns were observed for CHD and all-cause mortality and for both blacks and whites. CONCLUSION: For women with favorable levels for all 5 major risk factors at younger ages, CHD and CVD are rare; long-term and all-cause mortality are much lower compared with others.
