A captive audience: bringing the WISEWOMAN program to South Dakota prisoners.

PURPOSE: This analysis compares the baseline heart disease risk profile of WISEWOMAN participants screened in the South Dakota Women's Prison with the general WISEWOMAN population in South Dakota and explores the potential benefits of lifestyle intervention programs to reduce heart disease risk factors among women during incarceration. METHODS: Using baseline data for WISEWOMAN participants in South Dakota, we compared participants who were enrolled in prison (n = 261) with nonincarcerated participants enrolled throughout the state (n = 1,427). Using regression analysis and adjusting for demographics, we assessed differences in baseline prevalence of risk factors (hypertension, high cholesterol, smoking, and obesity), awareness and treatment of hypertension and high cholesterol, and attendance at lifestyle intervention sessions. RESULTS: Incarcerated participants had significantly lower (p < .01) total cholesterol (183 mg/dL) than nonincarcerated participants (199 mg/dL). However, a significantly higher (p < .03) percentage of incarcerated women (85%) than nonincarcerated women (54%) with high cholesterol were unaware of their condition. Despite the smoke-free status of the prison, 24% of incarcerated participants reported smoking. Attendance at lifestyle intervention sessions was significantly higher among incarcerated participants than among nonincarcerated participants with intervention take-up rates of 53% among incarcerated versus 23% among nonincarcerated women (p < .01) and intervention completion rates of 43% and 4% (p < .01). CONCLUSIONS: The results illustrate the need for screening and education programs in prisons. WISEWOMAN screenings helped identify undiagnosed cases of abnormal blood pressure and cholesterol, and educational interventions provided women with opportunities to improve their health. Such programs may also improve discharge planning and linkages between released women and community health providers.     

Cholesterol measures to identify and treat individuals at risk for coronary heart disease

BACKGROUND: Low-density lipoprotein (LDL)-based guidelines are currently used to initiate and monitor cholesterol-lowering therapy. METHODS: Using stratified analyses, data from the Framingham Heart Study and the Coronary Primary Prevention Trial were evaluated to determine whether (1) cholesterol levels (total cholesterol [TC] or LDL [low-density lipoprotein]) better discriminated risk for coronary heart disease (CHD) than cholesterol ratios (LDL/HDL [high-density lipoprotein] or TC/HDL); and (2) whether changes in ratios better predicted risk reduction than changes in levels. RESULTS: Individuals with similar LDL/HDL ratios had similar risks for CHD regardless of whether they had high LDL levels or low LDL levels (23% vs 23% for the CPPT, 13.8% vs 14% for FHS men, and 8.6% vs 10.9% for FHS women). Among men with similar initial LDL/HDL ratios and similar changes in LDL/HDL ratios, risks for CHD did not differ (20.3% compared with 21.0%; p =0.96) between those with the largest and smallest reductions in LDL levels (21.3% compared with 6.5%). Among men with similar initial LDL levels and similar LDL reductions, a 20% reduction in risk for CHD was seen (19.5% compared with 24.5%; p =0.005) between those with the largest and smallest reductions in LDL/HDL ratios (23% compared with 4.6%). TC/HDL had predictive ability similar to LDL/HDL. CONCLUSIONS: Cholesterol levels do not provide incremental predictive value over cholesterol ratios in identifying people at risk for CHD. Changes in ratios are better predictors of successful CHD risk reduction than changes in levels. Future guidelines should consider incorporating ratios in initiating and monitoring successful lipid-lowering therapy.     

Associations between plasma lipid concentrations and dietary, lifestyle and physical factors in the Oxford Vegetarian Study

Blood lipids data were available for 3773 subjects from a cohort study of 11 000 individuals, 6000 of whom do not eat meat. The effects of dietary, lifestyle and physical factors on concentrations of total and HDL cholesterol were investigated. Meat, cheese and dietary fibre, with smoking habit and height were found to be significantly related to total cholesterol in men. For women, meat, cheese, dietary fibre and tomatoes, and type of spreading fat were all significantly related to total cholesterol. Current alcohol consumption and body mass index were significantly related to HDL cholesterol concentration for men. The same factors, plus type of spreading fat, were related to HDL cholesterol levels in women. The findings provide further evidence of the hypolipidaemic effect of vegetarian or near vegetarian diets with a high fibre content and limited use of meat and cheese. The exclusion of meat from the diet might result in a 15–25% reduction in CHD risk.     

The effect of physician office visits on CHD risk factor modification as part of a worksite cholesterol screening program

BACKGROUND: Elevated serum cholesterol is a major risk factor for CHD. Primary prevention through behavioral modification has been designated first-line treatment for patients with elevated cholesterol. In this study, we assessed the impact of a physician office visit after a worksite cholesterol screening on self-reported changes in diet, weight loss, exercise, and smoking. We hypothesized that those individuals who had a physician office visit regarding cholesterol would make more changes in CHD risk factors than those who did not have such a visit. METHODS: A cohort of 4,928 participants from 33 work-sites in Massachusetts and Rhode Island had baseline CHD risk factors evaluated at a cholesterol screening and 4,473 were available at follow-up 6 months later by telephone interview. A total of 1,957 had elevated cholesterol levels (>/=200 mg;/dl) and were instructed to visit their physician, in addition to receiving educational materials related to CHD risk factor modification. RESULTS: Most individuals with elevated cholesterol levels had other prevalent self-reported CHD risk factors at baseline: 58% consumed high-fat diets (>30% fat), 43% were overweight, 60% had a sedentary lifestyle (sweat-related physical activity <3 x per week), and 22% were cigarette smokers. After 6 months of follow-up, 74% of participants with high-fat diets reported eating a lower fat diet, 71% of overweight participants reported weight loss, 53% of sedentary participants attempted to increase physical activity, and 38% of smokers decreased or quit cigarette smoking. Thirty-five percent of participants completed the referral for a physician office visit to discuss their elevated cholesterol determined at the baseline worksite screening. However, these individuals showed only a modest change (which was not statistically significant) in self-reported CHD risk factors compared with those who did not have follow-up physician visits after adjusting for age, sex, race, education, occupation, medical insurance, time since last doctor visit, diabetes, and hypertension. Objective measurements of serum cholesterol, body mass index, and dietary score were likewise modestly improved and not statistically significant. CONCLUSIONS: In 6 months of follow-up, high absolute levels of CHD risk factor modification were observed after a worksite cholesterol screening. A physician office visit added only a modest but not statistically significant benefit for further CHD risk factor modification. These findings indicate that the follow-up cholesterol-related physician visit had little added clinical benefit over the screening intervention alone.     

Information given to postmenopausal women on coronary computed tomography may influence cardiac risk reduction efforts

OBJECTIVE: Cardiovascular disease (CVD) is largely preventable through appropriate risk-factor modification. We sought to compare effects of comprehensive cardiac risk factor screening with and without computed tomography (CT) imaging of the coronary arteries on behavior change related to cardiac risk in postmenopausal women. STUDY DESIGN AND SETTING: 56 postmenopausal women were randomized to alternative screening programs and followed for 1 year. RESULTS: Subjects randomized (n=26) to the CT imaging group were shown images of their coronary arteries and received an interpretation from a radiologist. Most subjects in the CT group had a very low-risk (73.1%) coronary calcification score at baseline. Systolic blood pressure, total cholesterol, triglyceride, LDL, and cholesterol/HDL ratio declined significantly in the conventional screening group, but not in the CT imaging group (P<0.05). As compared to baseline values, study participation lead to significant reductions in total cholesterol, HDL, LDL, and blood pressure at 6 months (P<0.05) and triglyceride (P<0.05) at 12 months. CONCLUSIONS: CVD risk-screening programs can facilitate cardiac risk reduction in women, but these data do not support an independent benefit of coronary CT imaging in a low-to-moderate risk group. The possibility of a deleterious effect of imaging on patient commitment to lifestyle changes is suggested.     

Obesity and associated coronary heart disease risk factors in a population of low-income African-American and white women: the North Carolina WISEWOMAN project

BACKGROUND: Obesity has been associated with many co-occurring coronary heart disease (CHD) risk factors as well as CHD mortality. These associations have been shown to vary between African-American and white sample populations. METHODS: The authors examined whether obesity co-occurs with several CHD risk factors (diabetes, hypertension, hypercholesterolemia, low high-density lipoprotein cholesterol (HDL-C)), and estimated the 10-year risk for CHD in the North Carolina WISEWOMAN (Well Integrated Screening and Evaluation for Women Across the Nation) study sample. This sample includes low-income African-American and white women (> or = 50 years of age). RESULTS: Among white women (n = 1,284), 34% were overweight (BMI = 25.0-29.99 kg/m(2)) and 35% obese (BMI > or = 30 kg/m(2)); among African-American women (n = 754), 28% were overweight and 59% obese. Among obese and nonobese African-American women, the prevalence of three or more co-occurring risk factors was similar (obese = 17.7% (95% confidence interval (CI): 13.9, 21.6) and nonobese = 13.3% (95% CI: 8.7, 17.8)). By contrast, the prevalence among white women was greater among the obese (26.9% (95% CI: 22.9, 31.0)) than the nonobese (13.0% (95% CI: 9.7, 16.2)). CONCLUSIONS: The differences between and within African-American and white women may be accounted for by the high levels of HDL-C among obese and nonobese African-American women.     

The cardiovascular health impact of an incentive worksite health promotion program

PURPOSE: We examined the cardiovascular health profiles of benefit-eligible hospital employees who participated in an incentive screen program for 4 years. We also determined if cardiovascular health changes differed between participants (CHAP) who enrolled in structured follow-up risk reduction programs (CHAPplus) compared with those who chose less formal options (CHAPonly). METHODS: CHAP consisted of cardiovascular screens, results counseling, and encouragement to participate in education and behavioral support programs. After adjusting for gender, medication use, and baseline levels of adiposity and physical activity, cardiovascular health changes were tested with repeated-measures analysis of covariance (ANCOVA) among CHAP participants and by CHAP type. RESULTS: CHAP 4-year members (n = 278) were generally healthy and mostly women (87%) with an average age of 40.6 +/- .5 years at baseline. Despite increases in overall (p = .034) and central adiposity (p = .001), cardiovascular health improvements were found for the total cholesterol/high-density lipoprotein ratio (TCHOL/HDL; p = .007), low-density lipoprotein (p = .009), and blood glucose (p = .018) among 4-year CHAP members. CHAPonly employees showed greater improvements in most cardiovascular health indicators than CHAPplus participants, although these differences did not achieve statistical significance. DISCUSSION: Cardiovascular health improvements were associated with long-term participation in a hospital worksite incentive screen program. The cardiovascular health benefits tended to be greatest for CHAP employees who chose informal follow-up risk reduction options (CHAPonly) than those who enrolled in structured programs (CHAPplus).     

General health screenings to improve cardiovascular risk profiles: a randomized controlled trial in general practice with 5-year follow-up

OBJECTIVES: To investigate the impact of general health screenings and discussions with general practitioners on the cardiovascular risk profile of a random population of patients. STUDY DESIGN: A population-based, randomized, controlled, 5-year follow-up trial conducted in a primary care setting. POPULATION: The study group consisted of 2000 patients, randomly selected middle-aged men and women aged 30 to 50 years from family practices in the district of Ebeltoft, Denmark. Of these patients, 1507 (75.4%) agreed to participate. Patients were randomized into (1) a control group who did not receive health screenings, (2) an intervention group that received 2 health screenings, (3) an intervention group that received both the 2 screenings and a 45-minute follow-up consultation annually with their general practitioner. OUTCOMES MEASURED: Cardiovascular risk score (CRS), body mass index (BMI), blood pressure, serum cholesterol, carbon monoxide in expiratory air, and tobacco use. RESULTS: After 5 years, the CRS, BMI, and serum cholesterol levels were lower in the intervention groups compared with the control group. The improved outcome was greater in the baseline risk groups. The number of patients with elevated CRS in the intervention groups was approximately half the number of patients with elevated CRS in the control group. The difference was not a result of medication use. There was no difference between the group that received consultations after the screenings and the group that had health screenings alone. CONCLUSIONS: Health screenings reduced the CRS in the intervention groups. After 5 years of follow-up, the number of persons at elevated cardiovascular risk was about half that expected, based on the prevalence/proportion in a population not receiving the health checks (the control group). The impact of intervention was higher among at-risk individuals. Consultations about health did not appear to improve the cardiovascular profile of the study population.     

Environment, obesity, and cardiovascular disease risk in low-income women

BACKGROUND: Financially disadvantaged populations are more likely to live in communities that do not support healthy choices. This paper investigates whether certain characteristics of the built environment are associated with obesity or coronary heart disease (CHD) risk among uninsured low-income women. METHODS: Using a sample of 2001-2002 data from 2692 women enrolled in the WISEWOMAN program of the Centers for Disease Control and Prevention, the study team performed regression analysis (conducted in January-April 2005) to estimate body mass index (BMI) and the log of 10-year CHD risk as a function of the built environment and socioecologic measures. RESULTS: For women living in an environment of maximum mixed land use (i.e., an environment more conducive to healthy living), BMI was lower by 2.60 kg/m2 and CHD risk was lower by 20% than for women living in single-use uniform environments (i.e., environments less conducive to healthy living). An additional fitness facility per 1000 residents was associated with BMI and CHD risk that were lower by 1.39 kg/m2 and 15.1%, respectively. Crime was positively associated with BMI and CHD risk, whereas neighborhood affluence was negatively associated. Living in more racially segregated areas was negatively associated with CHD risk among black, Hispanic, and Asian women and positively associated with CHD risk among American Indian women. CONCLUSIONS: The built environment and socioecologic characteristics of financially disadvantaged women were associated with BMI and CHD risk. More research is needed to understand the effects of racial segregation or acculturation on health for specific subpopulations.     

A comparison of the effects of cholesterol on CHD mortality in black and white women: twenty-eight years of follow-up in the Charleston Heart Study.

The relationship between cholesterol and 28-year CHD mortality in women was evaluated in the Charleston Heart Study. Linear, quadratic, and cubic models were investigated using Cox proportional hazards regression analysis. In white women, the linear, quadratic, and cubic terms for cholesterol were significant suggesting an asymmetric J-shaped relationship. In black women, only the linear term in all three models was statistically significant suggesting an increasing CHD mortality rate with increasing cholesterol level. The lack of consistency of results by different statistical analyses in black women make conclusions concerning the nature of the relationship between cholesterol and CHD mortality less strong in black women than in white women. Compared with women having a cholesterol value equal to the mean of the group (241 mg/dl), white women having a cholesterol value one standard deviation above the mean (s = 52.5 mg/dl) had a 60% higher CHD mortality rate (hazard ratio = 1.6, 95% CI: 1.2-2.1). In black women, the estimated hazard ratio for a one standard deviation (s = 47.8 mg/dl) increase in cholesterol is 1.4 (95% CI: 1.03-1.8). The results suggest that the relationship of cholesterol to CHD mortality is different in white and black women. The relationship in white women appears to be curvilinear and represented by an asymmetric curve while the relationship in black women is not curvilinear and the overall pattern of association, while possibly linear, is equivocal.     

Hypercholesterolemia prevalence, awareness, and treatment in blacks and whites: the Minnesota Heart Survey

Two cross-sectional population-based surveys were conducted in 1985 and 1986 to describe cardiovascular risk factors in blacks and whites in the Twin Cities. A total of 1,254 blacks and 2,934 whites ages 35-74 years participated. The surveys consisted of a home interview followed by survey center visit during which nonfasting serum total cholesterol level was measured and medication use during the past year was reviewed. Age-adjusted mean values for serum total cholesterol were significantly higher among white than black participants for both men (207 vs 193 mg/dl, P less than 0.001) and women (206 vs 202 mg/dl, P less than 0.05). Blacks had significantly higher serum HDL cholesterol levels than whites (men, 49 vs 41 mg/dl, P less than 0.001; women, 56 vs 54 mg/dl, P less than 0.01). The age-adjusted prevalence of hypercholesterolemia (serum total cholesterol greater than or equal to 240 mg/dl on the day of survey and/or current use of cholesterol lowering medication) was significantly higher among white than black men (18.3% vs 12.2%, P less than 0.01). No significant race differences were noted for women (whites, 19.7% vs blacks, 16.6%). Among hypercholesterolemic men, 66% of whites current use of cholesterol lowering medication) was significantly higher among white than black men (18.3% vs 12.2%, P less than 0.01). No significant race differences were noted for women (whites, 19.7% vs blacks, 16.6%). Among hypercholesterolemic men, 66% of whites current use of cholesterol lowering medication) was significantly higher among white than black men (18.3% vs 12.2%, P less than 0.01). No significant race differences were noted for women (whites, 19.7% vs blacks, 16.6%). Among hypercholesterolemic men, 66% of whites and 80% of blacks were unaware of their condition; among women, 72% of whites and 79% of blacks were unaware. Among individuals told by a physician they had "high blood fats," 2.9% of whites and no blacks were using medication for elevated blood cholesterol levels, while 70% of whites and 63% of blacks reported being advised to follow a low-fat-low-cholesterol diet. These data emphasize the need for education programs for physicians and patients regarding detection and control of hypercholesterolemia.     

Adherence index based on the AHA 2006 diet and lifestyle recommendations is associated with select cardiovascular disease risk factors in older Puerto Ricans

In 2006, the AHA released diet and lifestyle recommendations (AHA-DLR) for cardiovascular disease (CVD) risk reduction. The effect of adherence to these recommendations on CVD risk is unknown. Our objective was to develop a unique diet and lifestyle score based on the AHA-DLR and to evaluate this score in relation to available CVD risk factors. In a cross-sectional study of Puerto Rican adults aged 45-75 y living in the greater Boston area, information was available for the following variables: diet (semiquantitative FFQ), blood pressure, waist circumference (WC), 10-y risk of coronary heart disease (CHD) (Framingham risk score), and fasting plasma lipids, serum glucose, insulin, and C-reactive protein (CRP) concentrations. We developed a diet and lifestyle score (AHA-DLS) based on the AHA-DLR. The AHA-DLS had both internal consistency and content validity. It was associated with plasma HDL cholesterol (P = 0.001), serum insulin (P = 0.0003), and CRP concentrations (P = 0.02), WC (P < 0.0001), and 10-y risk of CHD score (P = 0.01 in women). The AHA-DLS was inversely associated with serum glucose among those with a BMI < 25 (P = 0.01). Women and men in the highest quartile of the AHA-DLS had lower serum insulin (P-trend = 0.0003) and CRP concentrations (P-trend = 0.002), WC (P-trend = 0.0003), and higher HDL cholesterol (P-trend = 0.008). The AHA-DLS is a useful tool to measure adherence to the AHA-DLR and may be used to examine associations between diet and lifestyle behaviors and CVD risk.     

WISEWOMAN: addressing the needs of women at high risk for cardiovascular disease

In the United States, the cardiovascular health of women is affected by the disparate impact of cardiovascular diseases (CVDs) on many minority ethnic and racial groups. Women with low income also endure a disproportionate impact of the burden of CVD. The Centers for Disease Control and Prevention's (CDC's) Well-Integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN) Program was authorized by Congress in 1993 to extend the preventive health services offered to participants of the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). These are low-income, uninsured, and underinsured women. The intent was to expand services of an existing federal program to address cardiovascular health concerns in this vulnerable, high-risk population. CDC funds 19 state health departments and 2 tribal organizations (both in Alaska) to implement WISEWOMAN. In the first 2 years of the current 5-year funding cycle, which began in June 2008, the WISEWOMAN grantees succeeded in providing almost 78,000 screenings, of which 46% were to women of minority racial and ethnic groups. The individual successes are important, and the WISEWOMAN Program also has achieved success in the broader arenas of healthcare and the communities in which WISEWOMAN is implemented. WISEWOMAN impacts clinical systems of care, provider education, physician extenders, and the broader community and will continue to play an important role in connecting low-income, uninsured, and underinsured women with clinical systems of care and other community resources that will result in the prevention, treatment, and management of their CVD risk.     

Smoking,alcohol drinking and non-fatal coronary heart disease in Hong Kong Chinese

PURPOSE: To examine whether smoking, alcohol drinking and other risk factors were associated with non-fatal coronary heart disease (CHD) in Hong Kong Chinese.

METHODS: A case control study was carried out with 598 CHD hospital cases (431 men, 167 women) and 1100 community controls (663 men, 437 women). Standardized questionnaires were used and blood lipids were measured using standard methods.

RESULTS: Stepwise logistic regression models showed adjusted odds ratios (AOR) of 3.36 [95% confidence interval (CI): 2.35 to 4.81] for smoking and 0.32 (95% CI: 0.22 to 0.45) for alcohol drinking in men, and 6.50 (95% CI: 2.61 to 16.19) and 0.15 (95% CI: 0.08 to 0.30), respectively, in women. The OR increased with decreasing levels of high-density lipoprotein cholesterol (HDL) and increasing levels of triglycerides. No patterns were observed for body mass index (BMI), total and low-density lipoprotein cholesterol (LDL). The protective effect of drinking was observed for different types of drinks and frequency of drinking, although few drank alcohol more than 3 days per week.

CONCLUSIONS: Smoking was a strong risk factor and moderate alcohol drinking was a protective factor for CHD, and low HDL and high triglyceride levels were important risk factors in Hong Kong Chinese.     

Clustering of risk factors for coronary heart disease. the longitudinal relationship with lifestyle

PURPOSE: The purpose of this study was to investigate whether or not clustering of biological coronary heart disease (CHD) risk factors exists and to investigate the longitudinal relationship between lifestyle parameters (dietary intake, daily physical activity, smoking behaviour, alcohol consumption) and a biological CHD risk factor clustering score. This was defined as belonging to one or more gender specific 'high risk' quartiles for the following CHD risk factors: ratio between total serum cholesterol and high density lipoprotein cholesterol (TC:HDL), mean arterial blood pressure (MABP), body fatness [sum of skinfolds (SSF)], and cardiopulmonary fitness (VO2-max). METHODS: The data were derived from the Amsterdam Growth and Health Study, an observational longitudinal study in which six repeated measurements were carried out over a period of 15 years covering adolescence and young adulthood. The longitudinal relationships were analysed with generalized estimating equations. RESULTS: The results showed significant clustering for the TC:HDL ratio, SSF, and VO(2)-max. MABP was not significantly associated with the other CHD risk factors. Daily physical activity and alcohol consumption (only for males) were both inversely related to the clustering score. None of the other lifestyle parameters showed significant relationships with the clustering score. CONCLUSIONS: Based on this small longitudinal study, it can be stated that during adolescence and young adulthood both daily physical activity and alcohol consumption were related to a healthy CHD risk profile.     

Expanding the evidence for health promotion: developing best practices for WISEWOMAN

Implementing effective programs to prevent chronic disease holds the promise of reducing morbidity and mortality, reducing health disparities, and promoting health. Yet many programs have demonstrated success only in highly controlled research settings and few address the needs of low-income, uninsured, minority women. Well-Integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN), a demonstration program funded by the Centers for Disease Control and Prevention (CDC), that provides chronic disease risk factor screening and lifestyle interventions for low-income, 40-64-year-old women is learning from our own successful programs but is also charting new territory. As the CDC, state health departments, tribal organizations, and other WISEWOMAN partners approach the end of the first decade of WISEWOMAN demonstration projects, we are seeking to understand what has worked and what has not. This paper describes the rationale and proposed methodology for assessing best practices in the WISEWOMAN program through a participatory process that will examine scientific evidence and quantitative and qualitative program data. By emphasizing practicality in addition to scientific rigor, we are expanding the base of evidence considered to identify effective approaches for reducing cardiovascular disease (CVD) risk in financially disadvantaged, ethnically diverse women. Results of the 3-year project will be disseminated in a format intended to encourage programs to select and adapt those strategies best suited to their particular contexts.

Alcohol consumption, metabolic cardiovascular risk factors and hypertension in women

BACKGROUND: Low to moderate alcohol consumption is associated with reduced mortality, primarily due to a reduction in coronary heart disease (CHD). Conversely, heavy drinking increases mortality, mainly due to haemorrhagic stroke and non-cardiovascular diseases. It is important to identify the threshold of alcohol consumption above which the balance of risk and benefit becomes adverse. We examine the relationship between reported alcohol consumption, cardiovascular disease (CVD) risk factors, a 10-year CHD risk score and hypertension in women. METHODS: In all, 14 077 female employees aged 30-64 years, underwent screening for CVD risk factors. Information was available on a range of personal and lifestyle factors, including height, weight, blood pressure, lipids, lipoproteins, apolipoproteins and blood glucose. Age-adjusted means were computed for the risk factors in each of five groups of reported alcohol intake: <1 (non-drinkers), 1-7, 8-14, 15-21, > or = 22 units/week. The relationships between alcohol and a derived coronary risk score and hypertension were also examined. RESULTS: Increasing consumption was associated with an age-adjusted increase in high density lipoprotein cholesterol (HDL-C) and apolipoprotein A1 (both P < 0.001), a decline in body mass index, total cholesterol (TC), TC/HDL-C ratio, low density lipoprotein cholesterol (LDL-C) and apolipoprotein B (all P < 0.001), and no trend in triglycerides (P = 0.06), lipoprotein (a) (P = 0.09) or fasting glucose (P = 0.14). Except for LDL-C (P = 0.06) the relationships remained statistically significant after adjustment for possible confounders. Compared to non-drinkers, there was a decrease in 10-year CHD risk with increasing consumption, with the greatest reduction in risk in women consuming 1-7 units/week, odds ratio (OR) = 0.79, (95% CI: 0.72-0.87), and an increase in the prevalence of hypertension among those consuming 15-21 units/week, OR = 1.68, (95% CI: 1.14-2.46). CONCLUSIONS: This study provides biological support for an inverse association between alcohol intake and CHD in women, associated with favourable changes in lipid and lipoprotein risk factors. Women consuming 1-14 units/week had a reduction in CHD risk, but there was an increased prevalence of hypertension among those consuming > or = 15 units/week. These data suggest that, in terms of the reduced risk of CVD, women should be advised to restrict their alcohol consumption to < or = 14 units/week.     

Ethnicity and other characteristics predictive of coronary heart disease in a developing community: principal results of the St James Survey, Trinidad

A ten-year community survey was undertaken to investigate the high coronary heart disease (CHD) incidence among people of Indian (South Asian) descent in Trinidad, West Indies. Of 2491 individuals aged 35-69 years, 2215 (89%) were examined and 2069 (83%) found to be clinically free of CHD at baseline. After exclusion of 71 of minority ethnic groups, 786 African, 598 Indian, 147 European and 467 adults of Mixed descent were followed for CHD morbidity and mortality. In both sexes, adults of Indian origin had higher prevalence rates of diabetes mellitus, a low concentration of high-density lipoprotein (HDL) cholesterol, and recent abstinence from alcohol than other ethnic groups. Indian men also had larger skinfold thicknesses than other men. In participants free of CHD at entry, the age-adjusted relative risk of a cardiac event believed due to CHD was at least twice as high in Indian men and women as in other ethnic groups. In men, blood pressure, diabetes mellitus and low-density lipoprotein (LDL) cholesterol concentration were positively and independently related to risk of CHD, whereas alcohol consumption and HDL cholesterol concentration were inversely associated with risk after allowing for age and ethnic group. The ethnic contrasts in CHD persisted when these characteristics were taken into account. In the smaller sample of women, only ethnic group was predictive of CHD as defined. The failure of point estimates of risk to explain the high CHD incidence in Indians calls for focus on age of onset of risk and examination of other potential risk factors such as insulin concentration.
