Relation of alcohol intake to left ventricular mass: The Framingham Study.

Alcohol has direct toxic effects on the myocardium and is associated with elevated blood pressure, but its relation to left ventricular mass independent of blood pressure level has not been assessed. Reported alcohol intake and left ventricular mass measured by echocardiography were evaluated in 1,980 men and 2,511 women 17 to 90 years of age and free of cardiovascular disease in the Framingham offspring and cohort study. The relation of reported alcohol intake to left ventricular mass was assessed by gender-specific multivariate regression analysis adjusting for age, height, body mass index, systolic blood pressure, history of hypertension and cigarette smoking. Alcohol intake was positively associated with left ventricular mass in men (p less than 0.01) but not in women (p = 0.64). When stratified by beverage type, beer and wine in both men and women and liquor in men were positively related to left ventricular mass. The lack of association of total alcohol intake to left ventricular mass in women appeared to be due to a negative association (p less than 0.01) with liquor. The strongest positive associations were with wine in men (p less than 0.001) and beer in women (p less than 0.05). Alcohol use is independently associated with left ventricular mass; this association may vary by beverage type. In persons with unexplained left ventricular hypertrophy, excessive alcohol intake should be considered.     

Alcohol consumption and the risk of hypertension in women and men

Heavy alcohol intake increases the risk of hypertension, but the relationship between light-to-moderate alcohol consumption and incident hypertension remains controversial. We prospectively followed 28 848 women from the Women's Health Study and 13 455 men from the Physicians' Health Study free of baseline hypertension, cardiovascular disease, and cancer. Self-reported lifestyle and clinical risk factors were collected. In women, total alcohol intake was summed from liquor, red wine, white wine, and beer; men reported total alcohol intake from a single combined question. During 10.9 and 21.8 years of follow-up, 8680 women and 6012 men developed hypertension (defined as new physician diagnosis, antihypertensive treatment, reported systolic blood pressure >or=140 mm Hg, or diastolic blood pressure >or=90 mm Hg). In women, we found a J-shaped association between alcohol intake and hypertension in age- and lifestyle-adjusted models. Adding potential intermediates (body mass index, diabetes, and high cholesterol) attenuated the benefits of alcohol in the light-to-moderate range and strengthened the adverse effects of heavy alcohol intake. Beverage-specific relative risks paralleled those for total alcohol intake. In men, alcohol intake was positively and significantly associated with the risk of hypertension and persisted after multivariate adjustment. Models stratified by baseline systolic blood pressure (<120 versus >or=120 mm Hg) or diastolic blood pressure (<75 versus >or=75 mm Hg) did not alter the relative risks in women and men. In conclusion, light-to-moderate alcohol consumption decreased hypertension risk in women and increased risk in men. The threshold above which alcohol became deleterious for hypertension risk emerged at >or=4 drinks per day in women versus a moderate level of >or=1 drink per day in men.     

Type of alcohol consumed and mortality from all causes, coronary heart disease, and cancer

BACKGROUND: Although the J-shaped relation between alcohol intake and mortality has been reproduced in many large cohort studies, the question of whether the effects of beer, wine, and spirits differ remains controversial. OBJECTIVE: To examine the relation between intake of different types of alcohol and death from all causes, coronary heart disease, and cancer. DESIGN: Pooled cohort studies in which intake of beer, wine, and spirits; smoking status; educational level; physical activity; and body mass index were assessed at baseline. SETTING: Copenhagen, Denmark. PARTICIPANTS: 13 064 men and 11 459 women 20 to 98 years of age. MEASUREMENTS: Number of deaths and time to death from all causes, coronary heart disease, and cancer during follow-up. RESULTS: During 257 859 person-years of follow-up, 4833 participants died. J-shaped relations were found between total alcohol intake and mortality at various levels of wine intake. Compared with nondrinkers, light drinkers who avoided wine had a relative risk for death from all causes of 0.90 (95% CI, 0.82 to 0.99) and those who drank wine had a relative risk of 0.66 (CI, 0. 55 to 0.77). Heavy drinkers who avoided wine were at higher risk for death from all causes than were heavy drinkers who included wine in their alcohol intake. Wine drinkers had significantly lower mortality from both coronary heart disease and cancer than did non-wine drinkers (P = 0.007 and P = 0.004, respectively). CONCLUSION: Wine intake may have a beneficial effect on all-cause mortality that is additive to that of alcohol. This effect may be attributable to a reduction in death from both coronary heart disease and cancer.     

Relations between amount and type of alcohol and colon and rectal cancer in a Danish population based cohort study

BACKGROUND: There may be a weak association between total alcohol intake and colorectal cancer but the effect of different types of alcohol and effect on colon subsites have not been investigated satisfactorily. AIMS: To investigate the relationship between amount and type of alcohol and the risk of colon and rectal cancer. SUBJECTS: A population based cohort study with baseline assessment of weekly intake of beer, wine, and spirits, smoking habits, body mass index, educational level, and leisure time physical activity in Copenhagen, Denmark. The study included a random sample of 15 491 men and 13 641 women, aged 23-95 years. Incident cases of colorectal cancer were identified in the nationwide Danish Cancer Register. RESULTS: During a mean follow up of 14.7 years, we observed 411 colon cancers and 202 rectal cancers. We observed a dose-response relationship between alcohol and rectal cancer. Drinkers of more than 41 drinks a week had a relative risk of rectal cancer of 2.2 (95% confidence limits 1.0-4.6) compared with non-drinkers. Drinkers of more than 14 drinks of beer and spirits a week, but not wine, had a risk of 3.5 (1.8-6.9) of rectal cancer compared with non-drinkers, while those who drank the same amount of alcohol but including more than 30% of wine had a risk of 1.8 (1.0-3.2) of rectal cancer. No relation between alcohol and colon cancer was found when investigating the effects of total alcohol, beer, wine, and spirits, and percentage of wine of total alcohol intake. CONCLUSION: Alcohol intake is associated with a significantly increased risk of rectal cancer but the risk seems to be reduced when wine is included in the alcohol intake.     

Alcohol intake and fasting insulin in French men and women. The D.E.S.I.R. Study

BACKGROUND: To study the relation between alcohol consumption and the fasting insulin concentration in a French population with a range of alcohol intakes. METHODS: 2.406 men and 2.500 women, aged 30 to 65 years who were not known as diabetic and with a non-diabetic fasting plasma glucose<7.0 mmol/l were studied. Insulin was assayed by a specific micro-enzyme immunoassay and alcohol intake was from a self-questionnaire. RESULTS: Fasting insulin concentration showed an inverse linear association with alcohol consumption, after adjustment for age and possible confounding factors (p for trend<0.0001 men; p<0.002 women), with a 29% higher insulin in non-drinkers compared to very heavy drinkers (> 80 g/day) in men (p<0.0001) and a 23% and 26% difference when compared to heavy drinkers (41-80 g/day) in men and women respectively (p<0.0001, p<0.003). This relation did not differ significantly according to whether the alcohol was consumed as wine, beer/cider or spirits. Fasting plasma glucose modified the relation between alcohol and insulin in men: while the negative relation alcohol-insulin was strong for fasting plasma glucose<6.0 mmol/l (p<0.0001), there was no association above 6.0 mmol/l (p=0.4). CONCLUSION: There is an inverse relation between alcohol consumption and fasting insulin concentrations. Some studies have found a U shaped relation, and this is probably due to the inclusion of diabetic subjects. As hyperinsulinemia has been shown to be positively associated with cardiovascular disease, it may be one of the variables that explains the protective effect of moderate alcohol consumption on cardiovascular disease.     

Impact of alcohol intake on measures of lipid metabolism depends on context defined by gender,body mass index,cigarette smoking,and apolipoprotein E genotype

Hyperlipidemia, smoking, and obesity are well-known risk factors for cardiovascular disease. Conversely, moderate alcohol intake is associated with lower atherosclerosis risk. However, the influence of taking alcohol on the interrelationships of these factors in a particular context has not been thoroughly investigated. In this study, we asked whether the association between plasma measures of lipid metabolism and alcohol intake is dependent on context defined by gender, age, body mass index (BMI), smoking, and apolipoprotein E (APOE) genotype. Data were obtained in a sample of 869 women and 824 men who participated in the Quebec Heart Health Survey. There was no evidence that variation among APOE genotypes influenced the association between LDL cholesterol (LDL-C) or HDL cholesterol (HDL)-C and alcohol, after adjustment for age and BMI. Further, the positive (LDL-C and BMI) and the negative (HDL-C and BMI) associations that were observed in men and women with the epsilon3/2 and epsilon3/3 genotypes were not modified by alcohol intake. However, in women with the epsilon4/3 genotype only, we found a significant influence of an alcohol by BMI interaction on the prediction of total cholesterol, LDL-C, HDL-C, apoA-I, and apoB, and this interaction was influenced by the status of smoking. Whereas the influence of an alcohol by BMI interaction on total cholesterol and LDL-C was significant in smokers, its influence on HDL-C was significant only in non-smokers. This study emphasizes the context dependency of the influence of alcohol on lipid metabolism and demonstrates how biological, environmental, and genetic factors interact to determine cardiovascular disease risk.     

Prevalence of low HDL-cholesterol levels and associated factors among Koreans.

BACKGROUND: Low levels of high-density lipoprotein cholesterol (HDL-C), as well as high levels of low-densi-ty lipoprotein cholesterol, play a crucial role in the development of cardiovascular disease, which has shown a remarkable increase in Korea. METHOD AND RESULTS: Data were obtained from the 1998 Korean National Health and Nutrition Examination Survey, which was a cross-sectional national health survey. The total study population amounted to 7,300 individuals (3,283 men, 4,617 women), aged 18 years and older. The prevalence of low HDL-C levels, as proposed by National Cholesterol Education Program Adult Treatment Panel III or International Diabetes Federation, was 23.8% in men and 47.5% in women. After adjusting for independent variables, there was a greater risk of low HDL-C with an increased body mass index, abdominal obesity, cigarette smoking, and decreased alcohol consumption. Physically inactive lifestyle in men and low fat intake in women were identified as factors associated with low HDL-C level. CONCLUSIONS: The prevalence of low HDL-C levels is relatively high among Koreans, which may have important implications for public health. Identified associated factors should be considered for reducing the risk of low HDL-C levels in Koreans.     

Beneficial effects of a moderate consumption of red wine on cellular cholesterol efflux in young men

BACKGROUND AND AIM: Protection against coronary artery disease (CAD) by moderate alcohol consumption is thought to be partly mediated through an increase in high density lipoprotein (HDL) levels. The protective effect of HDL can be related to its role in reverse cholesterol transport. Some studies have shown that wine intake is associated with a lower CAD risk compared to other alcoholic beverages. METHODS AND RESULTS: In order to separate the possible beneficial effects of the alcoholic and the non-alcoholic components of red wine, three beverages were compared in a group of 56 healthy young men: red wine (W) (30 g alcohol/day), a solution with the same degree of alcohol (A) and alcohol-free red wine (AFW). Beverages were consumed in random order over a period of 14 days. W significantly increased serum HDL-C, Apo A-I, HDL3-C, LpA-I and LpA-I:A-II particles. With A, only ApoA-I, HDL3-C, LpA-I:A-II were increased, though triglycerides were also increased. AFW had no effect apart from decreasing HDL-C. Plasma CETP was never altered. Serum-promoted cellular cholesterol efflux was measured on 3H labelled Fu5AH cells. Fractional cholesterol efflux was increased only after W intake, by 7%. Efflux variations correlated positively with HDL-C, HDL3-C and HDL-phospholipid variations. CONCLUSIONS: A modest, specific beneficial effect of moderate red wine consumption was demonstrated in comparison to an alcoholic solution. This was due to its effects on lipoproteins and its stimulation of serum ability to induce efflux of cellular cholesterol.     

Waist circumference in relation to history of amount and type of alcohol: results from the Copenhagen City Heart Study

OBJECTIVE: To examine the long-term association between the amount and type of alcohol consumed and subsequent high waist circumference. DESIGN: Prospective population study with baseline assessment of alcohol intake, body mass index, smoking habit, physical activity, education, income and deliveries, and after 10 y, examination of waist circumference. SUBJECTS: A sample of 2916 men and 3970 women aged 20-83 y from Copenhagen City Heart Study, Denmark. MEASUREMENTS: A large waist circumference defined as a waist circumference more than 102 cm in men and 88 cm in women. RESULTS: The odds ratios of having a high waist circumference after 10 y showed a linear increase in both men and women, and they were 1.65 (95% confidence interval (CI) 1.07-2.55) in men and 2.16 (0.86-5.14) in women who drank more than 28 beverages per week of total alcohol compared to those who drank one to six beverages per week. Men drinking more than 21 beers per week had odds ratio of having a large waist circumference after 10 y of 1.63 (0.99-2.67) and women drinking more than 14 beers per week had odds ratio of 2.53 (0.92-6.34), compared to men and women who drank no beer. Also for spirits, there was an increase in both men and women. No linear trend was found for wine in either men or women. CONCLUSIONS: Moderate-to-high consumption of alcohol and of beer and spirits was associated with later high waist circumference, whereas moderate-to-high wine consumption may have the opposite effect.     

Alcohol intake and aortic stiffness in young men and women

BACKGROUND: Moderate alcohol consumption has been shown to protect against cardiovascular disease. Aortic stiffness can be regarded as a marker of cardiovascular disease risk. Previously we have shown an inverse to J-shaped association between alcohol intake and aortic stiffness in middle-aged and elderly men and postmenopausal women. OBJECTIVE: In the present study we examined whether a relation between alcohol intake and aortic stiffness is already present at a younger age. DESIGN: Cross-sectional data of a cohort study in men and women aged 28 years were analysed stratified by gender (240 men and 283 women). MEASUREMENTS: Alcohol intake was derived from a questionnaire and aortic stiffness was assessed by pulse-wave velocity measurement. RESULTS: In women an alcoholic beverage intake of >/=1 glass/day is associated with a 0.36 m/s (95% confidence interval, -0.58 to -0.14) lower pulse-wave velocity compared with non-drinkers. In men alcohol intake is also inversely related to pulse-wave velocity, but this was not significant. These findings were independent of age, blood pressure and heart rate. CONCLUSIONS: These findings suggest that moderate intake of alcohol may affect vascular stiffness at an early age, notably in women. These findings may be viewed as compatible with a vascular protective effect of alcohol that expresses well before the occurrence of symptomatic cardiovascular disease.     

Alcohol consumption, TaqIB polymorphism of cholesteryl ester transfer protein, high-density lipoprotein cholesterol, and risk of coronary heart disease in men and women.

AIMS: To investigate whether a common polymorphism in the cholesteryl ester transfer protein (CETP) gene modifies the relationship of alcohol intake with high-density lipoprotein cholesterol (HDL-C) and risk of coronary heart disease (CHD). METHODS AND RESULTS: Parallel nested case-control studies among women [Nurses' Health Study (NHS)] and men [Health Professionals Follow-up Study (HPFS)] where 246 women and 259 men who developed incident CHD were matched to controls (1:2) on age and smoking. The TaqIB variant and alcohol consumption were associated with higher HDL-C, with the most pronounced effects of alcohol among B2 carriers. In the NHS we did not find an inverse association between alcohol and CHD in B2 non-carriers (P trend: 0.5), but did among B2 carriers (P trend <0.01). Among non-carriers the odds ratio (OR) for CHD among women with an intake of 5-14 g/day was 1.4 (95% CI: 0.6-3.7) compared with non-drinkers, whereas among B2 carriers the OR was 0.4 (0.2-0.8). Results in men were less suggestive of an interaction; corresponding OR's were 1.9 (0.8-4.5) and 0.9 (0.5-1.6), for B2 non-carriers and carriers, respectively. CONCLUSIONS: The association of alcohol with HDL-C levels was modified by CETP TaqIB2 carrier status, and there was also a suggestion of a gene-environment interaction on the risk of CHD.     

The contribution of a moderate intake of alcohol to the presence of hypertension

The relationship between blood pressure and alcohol intake was examined in 2434 male and 1608 female London civil servants. These subjects had been selected from 24,000 office workers on the basis of responses to a health questionnaire. The men had an average blood pressure of 134/80 mmHg and consumed a mean of 62 g alcohol/week as beer, 28 g/week as wine or fortified wine and 18 g/week as spirits (a total of 11.8 drinks/week). The women had an average blood pressure of 133/79 mmHg and consumed 7 g alcohol/week as beer, 25 g/week as wine and 11 g/week as spirits (a total of 4.4 drinks/week). Twenty-five per cent of men and 24% of women had a casual diastolic pressure equal to or greater than 90 mmHg and were considered to have diastolic hypertension on the one occasion. There was no increase in either systolic or diastolic pressure in men until total alcohol intake exceeded 50 drinks/week. However, 1% of all men had hypertension associated with drinking alcohol and in those with hypertension, alcohol may have been the cause in between 4 and 9%. Defining 'hypertension' as a diastolic blood pressure of 90 mmHg or above on one occasion, 12-14% of people drinking more than 50 drinks of alcohol per week had hypertension associated with this intake of alcohol, and similarly, of those with both 'hypertension' and this level of intake, 36% could attribute their high blood pressure to their alcohol consumption.(ABSTRACT TRUNCATED AT 250 WORDS)     

Modification of the relationship between simple anthropometric indices and risk factors by ethnic background

Current targets for body mass index (BMI) and waist circumference (WC) may not be appropriate for those of South Asian origin. The objectives of this study were to determine whether the relationship between BMI and WC with risk factors for cardiovascular disease (CVD) is the same for men and women of South Asian and European descent. Apparently healthy men and women of European (n = 88) and South Asian (n = 93) descent were recruited from 3 hospital communities and assessed for BMI, WC, waist-to-hip ratio (WHR), blood pressure (BP), lipids, insulin, glucose, and CRP. The study cohort was stratified by sex, and regression analyses were performed with individual risk factors as outcomes and ethnicity with either BMI or WC as predictors adjusting for age and height (WC only). BMI and WC were similar between the European and South Asian men and women. South Asian men had significantly higher values for total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), triglycerides (TG), total cholesterol:high-density lipoprotein-cholesterol (HDL-C) and CRP, and significantly lower values of HDL-C. South Asian women had significantly higher values for TG, TC:HDL-C and CRP and significantly lower values of HDL-C, glucose, systolic BP and diastolic BP. In men, ethnicity was an independent predictor for all risk factors except for glucose and insulin, after adjusting for either BMI or WC independent of age and height. For women, ethnicity was an independent predictor for all risk factors except for total cholesterol (WC model only) and insulin (BMI model only), after adjusting for either BMI or WC independent of age and height. The relationship between BMI or WC and risk factors is such that men and women of South Asian descent present with a more adverse risk profile than those of European descent at the same BMI and/or WC.     

Beer, liquor, and wine consumption and serum uric acid level: the Third National Health and Nutrition Examination Survey

OBJECTIVE: To evaluate the relationship between intakes of beer, liquor, and wine and serum uric acid levels in a nationally representative sample of men and women. METHODS: Using data from 14,809 participants (6,932 men and 7,877 women) age > or =20 years in The Third National Health and Nutrition Examination Survey (1988-1994), we examined the relationship between intakes of beer, liquor, and wine and serum uric acid levels. Alcohol intake was assessed by a food frequency questionnaire. RESULTS: Serum uric acid levels increased with increasing beer or liquor intake but not with increasing wine intake. After adjusting for age, the difference in serum uric acid levels as compared with no intake increased with increasing beer or liquor intake (P values for trend <0.001), but the association was inverse with increasing wine intake (P for trend <0.001). After adjusting mutually for these alcoholic beverages and for other risk factors for hyperuricemia, including dietary risk factors, the associations were attenuated but remained significant for beer or liquor (multivariate difference per serving per day 0.46 mg/dl [95% confidence interval [95% CI] 0.32, 0.60] and 0.29 mg/dl [95% CI 0.14, 0.45], respectively; both P values for trend <0.01), but not for wine (0.04 mg/dl [95% CI -0.20, 0.11]; P for trend=0.6). CONCLUSION: These data suggest that the effect of individual alcoholic beverages on serum uric acid levels varies substantially: beer confers a larger increase than liquor, whereas moderate wine drinking does not increase serum uric acid levels.     

Cardiovascular risk profile and type of alcohol beverage consumption: a population-based study

AIMS: To determine the association between several cardiovascular risk factors with total alcohol and types of alcoholic beverage consumption. METHODS: The subjects were Spanish men (n = 2,383) and women (n = 2,535) aged 25-74 years who were examined in 1994-1995 and 1999-2000, in two population-based cross-sectional surveys in the north-east of Spain (Gerona). Information of total amount and type of alcohol consumption, educational level, smoking, leisure-time physical, antihypertensive and hyperlipidemic drug treatment was obtained through structured questionnaires. The cardiovascular risk factors total cholesterol, HDL cholesterol, triglycerides, fasting glucose, fibrinogen, lipoprotein (a), heart rate and systolic and diastolic blood pressures were determined. RESULTS: Men consumed significantly more alcohol than women (19.5 vs. 4.5 g/day, respectively) and the prevalence of elevated alcohol consumption (>2 glasses of wine/day) also was higher in men (35.3%) than women (3.5%). Total alcohol intake was significantly related with HDL cholesterol and fibrinogen improvements in both genders. In contrast, total cholesterol, triglycerides, heart rate, and systolic and diastolic blood pressures were directly and significantly (p < 0.05) associated with total alcohol consumption in men but not in women. Wine drinking, particularly in women, was associated with a healthy cardiovascular risk profile. Most of the observed significant associations between type of alcohol beverage and CHD risk factors disappeared after controlling for total alcohol consumption and other confounders. CONCLUSIONS: Alcohol consumption was favorably related to the cardiovascular risk profile in women but not in men. The relationship of alcohol beverages seems to be mediated by the total alcohol content rather than by the type of beverage itself.     

HDL-cholesterol in a sample of black adults: the Framingham Minority Study

A group of 100 adult black residents of Framingham, MA were examined and their plasma lipids were determined by the Framingham Heart Study Lipoprotein Laboratory. The age range of the participants was 20-69 yr, and the mean age was 42 yr for both sexes. The mean plasma total cholesterol, HDL-cholesterol (HDL-C), and triglyceride (TG) values for the 45 black men were 184,37.2, and 78 mg/dl, respectively. The corresponding levels for the 55 black women were 192,50.4, and 49. Even after adjusting for obesity, alcohol intake, and cigarette use, the HDL-C levels among the blacks were significantly lower (p less than 0.001) than the levels for Framingham white men and women. This black sample is more highly educated than black groups previously studied, and appears to be as active as the Framingham white sample. We conclude that this black population has quite low HDL-C levels, and the results suggest that the lipoprotein distributions in this group differ from those previously reported for blacks.     

Alcohol intake, type of beverage, and risk of breast cancer in pre- and postmenopausal women

BACKGROUND: Most studies of the relation between alcohol consumption and breast cancer have shown a modestly increased risk, although the results are still conflicting. METHODS: The aim of this prospective population-based cohort study was to assess the influence of alcohol intake and type of beverage (beer, wine, or spirits) on breast cancer risk in relation to menopausal status. Among 13,074 women aged 20 to 91 years, we examined the relationship between breast cancer risk, total alcohol intake, and type of alcohol in relation to menopausal status. The women were classified as premenopausal or as postmenopausal at younger than 70 years or 70 years or more. RESULTS: During follow-up, 76 premenopausal and 397 postmenopausal women developed breast cancer. Premenopausal women who had an intake of more than 27 drinks per week had a relative risk of breast cancer of 3.49 (95% confidence limits, 1.36-8.99) compared with light drinkers (p = 0.011), whereas there were no differences in risk in the lower-intake categories. The increased risk of breast cancer among premenopausal women was independent of the type of alcohol. Postmenopausal women older than 70 years of age who had an intake of more than six drinks per week of spirits had a relative risk of breast cancer of 2.43 (95% confidence limits, 1.41-4.20) compared with women who consumed less than one drink of spirits per week (p = 0.0014). CONCLUSIONS: Total alcohol intake of more than 27 drinks per week increases breast cancer risk in premenopausal women independently of the type of alcohol. Among postmenopausal women, an intake of spirits of more than six drinks per week increases breast cancer risk.     

Evidence for a Positive Association Between Pulmonary Function and Wine Intake in a Population-Based Study

Background: Lung function is a strong predictor of cardiovascular and all-cause mortality. Previous studies suggest that alcohol exposure may be linked to impaired pulmonary function through oxidant-antioxidant mechanisms. Alcoholic beverages may be an important source of oxidants and antioxidants. We analyzed the relation of beverage-specific alcohol intake with forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) in a random sample of 1555 residents of Western New York, USA. Methods: We expressed pulmonary function as percent of predicted normal FEV1 (FEV1%) and FVC (FVC%) after adjustment for height, age, gender, and race. To obtain information on alcohol intake we used a questionnaire that reliably queries total alcohol and beverage-specific recent (past 30 days) and lifetime alcohol consumption. Results: Using multiple linear regression analysis after adjustment for covariates (pack-years of smoking, weight, smoking status, education, nutritional factors, and for FEV1%, in addition, eosinophil count), we observed no significant correlation between total alcohol intake and lung function. However, we found positive associations of recent and lifetime wine intake with FEV1% and FVC%. When we analyzed white and red wine intake separately, the association of lung function with red wine was weaker than with white wine. Conclusion: While total alcohol intake was not related to lung function, wine intake showed a positive association with lung function. Although we cannot exclude residual confounding by healthier lifestyle in wine drinkers, differential effects of alcoholic beverages on lung health may exist.     

Is the relationship between type of alcohol and mortality influenced by socio‐economic status?

OBJECTIVES: To assess the impact of socio-economic status on the relationship between type of alcohol and all-cause mortality. DESIGN: A prospective population study. SETTING: The Copenhagen City Heart Study, Denmark. SUBJECTS: A total of 14,223 men and women participated in the first examination of The Copenhagen City Heart Study in 1976-1978. The participants were followed up until 18th of September 2001 during which 7208 persons died. The effect of beer, wine and spirits on mortality was stratified according to levels of education, income and cohabitation, and the association was examined after controlling for intake of the other types of alcohol, and for sex, smoking, physical activity and body mass index. MAIN OUTCOME MEASURES: Number and time of death from all causes. RESULTS: Consumers of wine were better educated and wealthier compared with beer and spirits drinkers. The association between type of beverage and mortality was noticed to differ according to socio-economic level, especially where the apparent protective effect of wine consumption tended to be strongest in the lower income and educational groups. CONCLUSIONS: This study finds the specific effects of beer, wine or spirits to moderately diverge in the socio-economic groups. Future studies addressing the association between the type of beverage and mortality may need to more thoroughly take socio-economic factors into account.     

Evidence for a regional component of body fatness in the association with serum lipids in men and women

Four hundred and seventy-two subjects (234 women and 238 men), 18 to 50 years of age, participated in percent body fat determination from underwater weighing, assessment of 6 subcutaneous skinfold thicknesses, and a 12-hour fast blood sampling for measurement of serum triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), total cholesterol (CHOL), and HDL-C/CHOL ratio. Even though women were significantly fatter than men, they had lower TG, CHOL, and higher values of HDL-C/CHOL ratio. Correlational and variance analyses showed that body fatness seemed to be more closely associated with serum lipids in men than in women. Moreover, the relationship between each skinfold and serum lipids indicated that subscapular and abdominal fat depots are more closely associated with serum lipids than other fat depots in men. In women, correlations were lower and regional differences attenuated. Furthermore, the regional trend observed in men remained significant after correction for concomitant variables such as age, cigarette smoking, habitual energy intake and energy expenditure, maximal aerobic power, and alcohol consumption. However, no effect of increasing body fatness was noted on HDL-C levels in women. Results of this study suggest that measurement of subscapular and abdominal fat should be considered when interpreting the blood lipid profile, particularly in males. A higher percentage of fat must be present in women than in men to observe alterations in serum lipids.
