Employment status, social ties, and caregivers' mental health.

The purpose of this study of mid-life and older women was to assess the relation between informal care provision and depressive symptoms, taking into account concurrent demands on women's time (including multiple caregiving roles and employment outside the home) as well as participants' access to potentially supportive social ties. This cross-sectional study included women ages 46-71, free from major disease, who provided complete health and social information in the 1992 Nurses' Health Study follow-up survey (n = 61,383). In logistic regression models predicting depressive symptoms, we examined the interaction between employment outside the home and informal care provision for a disabled or ill spouse or parent. We also investigated level of social ties, measured with the Berkman-Syme Social Network Index, as a potential modifier of the association between informal care provision and depressive symptoms. In all analyses, higher weekly time commitment to informal care for a spouse or parent was associated with increased risk of depressive symptoms. This relationship persisted whether women were not employed outside the home, were employed full-time, or were employed part-time. Higher weekly time commitment to informal care provision was associated with increased risk of depressive symptoms whether women were socially integrated or socially isolated. However, both informal care provision and social ties were potent independent correlates of depressive symptoms. Therefore, women who reported high spousal care time commitment and few social ties experienced a dramatic elevation in depressive symptoms, compared to women with no spousal care responsibilities and many social ties (OR for depressive symptoms=11.8; 95% CI 4.8, 28.9). We observed the same pattern among socially isolated women who cared for their parent(s) many hours per week, but the association was not as strong (OR for depressive symptoms=6.5; 95% CI 3.4, 12.7). In this cross-sectional study, employment status did not seem to confer additional mental health risk or benefit to informal caregivers, while access to extensive social ties was associated with more favorable caregiver health outcomes.

Magnesium intake and risk of type 2 diabetes in men and women.

OBJECTIVE: To examine the association between magnesium intake and risk of type 2 diabetes. RESEARCH DESIGN AND METHODS: We followed 85,060 women and 42,872 men who had no history of diabetes, cardiovascular disease, or cancer at baseline. Magnesium intake was evaluated using a validated food frequency questionnaire every 2-4 years. After 18 years of follow-up in women and 12 years in men, we documented 4,085 and 1,333 incident cases of type 2 diabetes, respectively. RESULTS: After adjusting for age, BMI, physical activity, family history of diabetes, smoking, alcohol consumption, and history of hypertension and hypercholesterolemia at baseline, the relative risk (RR) of type 2 diabetes was 0.66 (95% CI 0.60-0.73; P for trend <0.001) in women and 0.67 (0.56-0.80; P for trend <0.001) in men, comparing the highest with the lowest quintile of total magnesium intake. The RRs remained significant after additional adjustment for dietary variables, including glycemic load, polyunsaturated fat, trans fat, cereal fiber, and processed meat in the multivariate models. The inverse association persisted in subgroup analyses according to BMI, physical activity, and family history of diabetes. CONCLUSIONS: Our findings suggest a significant inverse association between magnesium intake and diabetes risk. This study supports the dietary recommendation to increase consumption of major food sources of magnesium, such as whole grains, nuts, and green leafy vegetables.

Folate, vitamin B6, and B12 intakes in relation to risk of stroke among men.

BACKGROUND AND PURPOSE: Folate, vitamin B6, and B12 deficiency are related to elevated blood homocysteine level. However, the effects of intakes of these vitamins on risk of stroke are still uncertain. This study examines intakes of folate, vitamin B6, and B12 in relation to risk of ischemic and hemorrhagic stroke. METHODS: We enrolled 43 732 men, aged 40 to 75 years, who were free of cardiovascular diseases and diabetes at baseline. Participants were followed from 1986 to 2000. Dietary information was assessed every 4 years using a detailed and validated semiquantitative food frequency questionnaire. The main outcome measures were incident ischemic and hemorrhagic strokes. RESULTS: A total of 725 incident strokes, including 455 ischemic, 125 hemorrhagic, and 145 unknown types of stroke, were documented during the 14-year follow-up. After adjustment for major lifestyle and dietary factors, intake of folate was associated with a significantly lower risk of ischemic but not hemorrhagic stroke. The multivariate relative risk of ischemic stroke was 0.71 (95% CI, 0.52 to 0.96; P for trend=0.05) for men in the highest quintile of intake compared with those who in the lowest quintile. Intake of vitamin B12, but not B6, was also inversely associated with risk of ischemic stroke. CONCLUSIONS: Our findings suggest that increased folate intake is associated with decreased risk of ischemic stroke in men.

Prospective study of selenium levels in toenails and risk of coronary heart disease in men.

Selenium is a trace mineral that plays a role in antioxidant defenses as a component of glutathione peroxidase. Epidemiologic findings on the relation of selenium status to risk of heart disease are inconsistent. Therefore, the authors investigated prospectively the association between toenail selenium levels and risk of coronary heart disease (CHD) in a case-control study nested within the Health Professionals Follow-up Study. Between 1987 and 1992, 470 CHD cases were newly diagnosed. A control matched to each case on age, smoking status, and date of toenail return was chosen. Toenail selenium levels analyzed by neutron activation were not associated with risk of total CHD after adjustment for age and smoking and other CHD risk factors (highest quintile vs. lowest: odds ratio (OR) = 0.86, 95% confidence interval (CI): 0.55, 1.32; p-trend = 0.75). Selenium level was inversely associated with risk of nonfatal myocardial infarction for extreme quintiles (OR = 0.54, 95% CI: 0.31, 0.93; p-trend = 0.07), was less so for fatal CHD (OR = 0.79, 95% CI: 0.39, 1.60; p-trend = 0.61), and was directly associated with coronary revascularization procedures (OR = 2.38, 95% CI: 1.11, 5.09; p-trend = 0.02). Although these findings suggest no overall relation between selenium status and CHD, a specific protective role for myocardial infarction cannot be excluded.

Joint association of alcohol and folate intake with risk of major chronic disease in women.

Alcohol interferes with folate metabolism and has opposing effects on the risks of cardiovascular disease and cancer. The authors examined the joint association of alcohol and folate intake with risk of major chronic disease, defined as fatal or nonfatal cardiovascular disease or cancer, or other nontraumatic death. This study included 83,929 women aged 34-59 years with no previous history of cardiovascular disease or cancer who provided dietary data in 1980. During 16 years of follow-up, the authors documented 10,666 new cases of major chronic disease. Overall, heavy drinkers (>30 g/day) with a lower total folate intake (<180 micro g/day) had the highest risk; in comparison with abstainers with a folate intake of 400-599 micro g/day, the multivariate relative risk was 1.36 (95% confidence interval: 1.10, 1.70). However, the increased risk of major chronic disease associated with heavy drinking was largely diminished among women with a higher folate intake (p for interaction = 0.02). The positive association between heavy alcohol/low folate intake and risk of major chronic disease was most apparent among women younger than age 60 years. Adequate folate intake may be important in the primary prevention of overall major chronic disease in women, especially among younger women consuming more than two alcoholic drinks per day.

Dietary fat intake and risk of stroke in male US healthcare professionals: 14 year prospective cohort study.

OBJECTIVE: To examine the association between intake of total fat, specific types of fat, and cholesterol and risk of stroke in men. Design and setting Health professional follow up study with 14 year follow up. PARTICIPANTS: 43 732 men aged 40-75 years who were free from cardiovascular diseases and diabetes in 1986. MAIN OUTCOME MEASURE: Relative risk of ischaemic and haemorrhagic stroke according to intake of total fat, cholesterol, and specific types of fat. RESULTS: During the 14 year follow up 725 cases of stroke occurred, including 455 ischaemic strokes, 125 haemorrhagic stokes, and 145 strokes of unknown type. After adjustment for age, smoking, and other potential confounders, no evidence was found that the amount or type of dietary fat affects the risk of developing ischaemic or haemorrhagic stroke. Comparing the highest fifth of intake with the lowest fifth, the multivariate relative risk of ischaemic stroke was 0.91 (95% confidence interval 0.65 to 1.28; P for trend = 0.77) for total fat, 1.20 (0.84 to 1.70; P = 0.47) for animal fat, 1.07 (0.77 to 1.47; P = 0.66) for vegetable fat, 1.16 (0.81 to 1.65; P = 0.59) for saturated fat, 0.91 (0.65 to 1.28; P = 0.83) for monounsaturated fat, 0.88 (0.64 to 1.21; P = 0.25) for polyunsaturated fat, 0.87 (0.62 to 1.22; P = 0.42) for trans unsaturated fat, and 1.02 (0.75 to 1.39; P = 0.99) for dietary cholesterol. Intakes of red meats, high fat dairy products, nuts, and eggs were also not appreciably related to risk of stroke. CONCLUSIONS: These findings do not support associations between intake of total fat, cholesterol, or specific types of fat and risk of stroke in men.

Body mass index and risk of prostate cancer in U.S. health professionals.

The relationship between body mass index (BMI) and prostate cancer risk may be complex because obesity is associated with various hormonal factors and because the influence of BMI may differ according to whether the cancers are hereditary or sporadic. We used data from the Health Professionals Follow-Up Study, in which 2896 incident cases of prostate cancer were reported from February 1, 1986, through January 31, 2000, to determine prospectively whether BMI was associated with the risk of hereditary (men <60 years of age or with a positive family history of prostate cancer) and sporadic (men > or =60 years of age and without such a family history) prostate cancer. The risk of prostate cancer in men with a higher BMI (> or =30 kg/m2) was lower than that in men with a lower BMI (23-24.9 kg/m2) but only if they were younger (<60 years old) (relative risk = 0.52, 95% confidence interval = 0.33 to 0.83; P(trend)<.001) or had a family history of prostate cancer (relative risk = 0.74, 95% confidence interval = 0.45 to 1.19; P(trend) =.01). However, for groups with more sporadic cancers, BMI had a weak, non-statistically significant positive association with prostate cancer. We observed statistically significant interactions between BMI and age (P(interaction)<.001, two-sided Wald test) and between BMI and family history of prostate cancer (P(interaction) =.006, two-sided Wald test). Patterns for BMI and waist circumference were similar. Because obesity is associated with lower circulating concentrations of testosterone, our results suggest the hypothesis that androgens may play a more direct role for early-onset or hereditary prostate cancers than for sporadic prostate cancers.

Sexual function in men older than 50 years of age: results from the health professionals follow-up study.

BACKGROUND: Although many studies have provided data on erectile dysfunction in specific settings, few studies have been large enough to precisely examine age-specific prevalence and correlates. OBJECTIVE: To describe the association between age and several aspects of sexual functioning in men older than 50 years of age. DESIGN: Cross-sectional analysis of data from a prospective cohort study. SETTING: U.S. health professionals. PARTICIPANTS: 31 742 men, age 53 to 90 years. MEASUREMENTS: Questionnaires mailed in 2000 asked about sexual function, physical activity, body weight, smoking, marital status, medical conditions, and medications. Previous biennial questionnaires since 1986 asked about date of birth, alcohol intake, and other health information. RESULTS: When men with prostate cancer were excluded, the age-standardized prevalence of erectile dysfunction in the previous 3 months was 33%. Many aspects of sexual function (including overall function, desire, orgasm, and overall ability) decreased sharply by decade after 50 years of age. Physical activity was associated with lower risk for erectile dysfunction (multivariable relative risk, 0.7 [95% CI, 0.6 to 0.7] for >32.6 metabolic equivalent hours of exercise per week vs. 0 to 2.7 metabolic equivalent hours of exercise per week), and obesity was associated with higher risk (relative risk, 1.3 [CI, 1.2 to 1.4] for body mass index >28.7 kg/m2 vs. <23.2 kg/m2). Smoking, alcohol consumption, and television viewing time were also associated with increased prevalence of erectile dysfunction. Men who had no chronic medical conditions and engaged in healthy behaviors had the lowest prevalence. CONCLUSIONS: Several modifiable health behaviors were associated with maintenance of good erectile function, even after comorbid conditions were considered. Lifestyle factors most strongly associated with erectile dysfunction were physical activity and leanness.

Habitual dietary intake of n-3 and n-6 fatty acids in relation to inflammatory markers among US men and women.

BACKGROUND: Polyunsaturated fatty acid intake favorably affects chronic inflammatory-related diseases such as cardiovascular disease; however, high intake of n-6 fatty acids may attenuate the known beneficial effects of n-3 fatty acids. METHODS AND RESULTS: We investigated habitual dietary n-3 fatty acid intake and its interaction with n-6 fatty acids in relation to the plasma inflammatory markers C-reactive protein, interleukin 6, and soluble tumor necrosis factor receptors 1 and 2 (sTNF-R1 and R2) among 405 healthy men and 454 healthy women. After adjustment for other predictors of inflammation, intake of the n-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) was inversely associated with plasma levels of sTNF-R1 and sTNF-R2 (P=0.03 and P<0.001, respectively) and somewhat less so for C-reactive protein (P=0.08). n-3 alpha-linolenic acid and n-6 cis-linoleic acid were not significantly related to the inflammatory markers. We found little if any association between n-3 fatty acid (EPA+DHA) intake and tumor necrosis factor receptors among participants with low intake of n-6 but a strong inverse association among those with high n-6 intake (P=0.04 and 0.002 for interaction of n-3 with n-6 on sTNF-R1 and sTNF-R2, respectively). CONCLUSIONS: These results suggest that n-6 fatty acids do not inhibit the antiinflammatory effects of n-3 fatty acids and that the combination of both types of fatty acids is associated with the lowest levels of inflammation. The inhibition of inflammatory cytokines may be one possible mechanism for the observed beneficial effects of these fatty acids on chronic inflammatory-related diseases.

Alcohol drinking patterns and risk of type 2 diabetes mellitus among younger women.

OBJECTIVE: To examine the relationship between alcohol consumption and the incidence of type 2 diabetes mellitus among relatively young and middle-aged women. METHODS: In a prospective study, 109 690 women, aged 25 to 42 years, without a history of coronary heart disease, stroke, cancer, or diabetes mellitus completed a detailed lifestyle and medical history questionnaire in 1989. During 10 years of follow-up, we documented 935 incident cases of type 2 diabetes mellitus. RESULTS: We found a nonlinear relationship between alcohol consumption and risk of type 2 diabetes mellitus after adjustment for multiple confounders, including body mass index, smoking, physical activity, and family history of diabetes mellitus (quadratic trend P =.003). Compared with lifelong abstainers, the adjusted relative risks (95% confidence intervals) were 0.80 (0.66-0.96) for those consuming 0.1 to 4.9 g/d, 0.67 (0.50-0.89) for those consuming 5.0 to 14.9 g/d, 0.42 (0.20-0.90) for those consuming 15.0 to 29.9 g/d, and 0.78 (0.34-1.78) for those consuming 30.0 g/d or more. Further adjustment for dietary factors, including glycemic load, trans-fatty acid, polyunsaturated fat, and total fiber intake, did not appreciably alter these findings. The inverse association with light to moderate drinking was most apparent in women who reported wine or beer drinking. Women who reported 30.0 g/d or more of liquor intake showed a significantly increased risk of diabetes mellitus compared with those who did not report liquor intake (adjusted relative risk, 2.50; 95% confidence interval, 1.00-6.23). CONCLUSION: Light to moderate alcoholic beverage consumption may be associated with a lower risk of type 2 diabetes mellitus among women aged 25 to 42 years, although this benefit may not persist at higher levels.

Physical activity in relation to cardiovascular disease and total mortality among men with type 2 diabetes.

BACKGROUND: The present study was conducted to examine the relationship of physical activity with risk of cardiovascular disease (CVD) and mortality among men with type 2 diabetes. CVD risk and mortality are increased in type 2 diabetes. Few epidemiological studies have investigated the effect of physical activity on these outcomes among type 2 diabetics. METHODS AND RESULTS: Of the 3058 men who reported a diagnosis of diabetes at age 30 years or older in the Health Professionals' Follow-up Study (HPFS), we excluded 255 who reported a physical impairment. In the remaining 2803 men, physical activity was assessed every 2 years; 266 new cases of CVD and 355 deaths of all causes were identified during 14 years of follow-up. Relative risks of CVD and death were estimated from Cox proportional hazards analysis with adjustment for potential confounders. The multivariate relative risks of CVD incidence corresponding to quintiles of total physical activity were 1.0, 0.87, 0.64, 0.72, and 0.67 (Ptrend=0.07). The corresponding multivariate relative risks for total mortality were 1.0, 0.80, 0.57, 0.58, and 0.58 (Ptrend=0.005). Walking was associated with reduced risk of total mortality. Relative risks across quintiles of walking were 1.0, 0.97, 0.87, 0.97, and 0.57 (Ptrend=0.002). Walking pace was inversely associated with CVD, fatal CVD, and total mortality independently of walking hours. CONCLUSIONS: Physical activity was associated with reduced risk of CVD, cardiovascular death, and total mortality in men with type 2 diabetes. Walking and walking pace were associated with reduced total mortality.

Cardiovascular morbidity and mortality in women diagnosed with rheumatoid arthritis.

BACKGROUND: Rheumatoid arthritis may be associated with an increased risk of cardiovascular disease. We compared the incidence rates of myocardial infarction and stroke in subjects with and without rheumatoid arthritis. METHODS AND RESULTS: A prospective cohort study was conducted among the 114 342 women participating in the Nurses' Health Study who were free of cardiovascular disease and rheumatoid arthritis at baseline in 1976. All self-reported cases of rheumatoid arthritis were confirmed by medical record review. Fatal and nonfatal myocardial infarctions and strokes were similarly confirmed. Multivariate pooled logistic regression was used to adjust for potential cardiovascular risk factors. Five hundred twenty-seven incident cases of rheumatoid arthritis and 3622 myocardial infarctions and strokes were confirmed during 2.4 million person-years of follow-up. The adjusted relative risk of myocardial infarction in women with rheumatoid arthritis compared with those without was 2.0 (95% confidence interval [CI], 1.23 to 3.29). For stroke, the adjusted relative risk was 1.48 (95% CI, 0.70 to 3.12). Women who had rheumatoid arthritis for at least 10 years had a risk for myocardial infarction of 3.10 (95% CI, 1.64 to 5.87). CONCLUSION: In this large prospective cohort of women, participants with rheumatoid arthritis had a significantly increased risk of myocardial infarction but not stroke compared with those without rheumatoid arthritis. If these data are confirmed, aggressive coronary heart disease prevention strategies should be tested for persons with rheumatoid arthritis.

Roles of drinking pattern and type of alcohol consumed in coronary heart disease in men.

BACKGROUND: Although moderate drinking confers a decreased risk of myocardial infarction, the roles of the drinking pattern and type of beverage remain unclear. METHODS: We studied the association of alcohol consumption with the risk of myocardial infarction among 38,077 male health professionals who were free of cardiovascular disease and cancer at base line. We assessed the consumption of beer, red wine, white wine, and liquor individually every four years using validated food-frequency questionnaires. We documented cases of nonfatal myocardial infarction and fatal coronary heart disease from 1986 to 1998. RESULTS: During 12 years of follow-up, there were 1418 cases of myocardial infarction. As compared with men who consumed alcohol less than once per week, men who consumed alcohol three to four or five to seven days per week had decreased risks of myocardial infarction (multivariate relative risk, 0.68 [95 percent confidence interval, 0.55 to 0.84] and 0.63 [95 percent confidence interval, 0.54 to 0.74], respectively). The risk was similar among men who consumed less than 10 g of alcohol per drinking day and those who consumed 30 g or more. No single type of beverage conferred additional benefit, nor did consumption with meals. A 12.5-g increase in daily alcohol consumption over a four-year follow-up period was associated with a relative risk of myocardial infarction of 0.78 (95 percent confidence interval, 0.62 to 0.99). CONCLUSIONS: Among men, consumption of alcohol at least three to four days per week was inversely associated with the risk of myocardial infarction. Neither the type of beverage nor the proportion consumed with meals substantially altered this association. Men who increased their alcohol consumption by a moderate amount during follow-up had a decreased risk of myocardial infarction.

Increased physical activity decreases periodontitis risk in men.

BACKGROUND: Increased physical activity improves insulin sensitivity and glucose metabolism, and may therefore affect incidence of periodontitis. METHODS: We studied the association of physical activity, walking and periodontitis in 39,461 male, US based, health professionals, 40-75 years old at baseline, more than half of whom were dentists, being followed up continuously since 1986. Participants were free of periodontitis, coronary heart disease and stroke at the start of follow-up. Physical activity and periodontitis were measured by validated questionnaires (expressed in metabolic equivalents--METs); the first report of professionally diagnosed periodontitis was considered a case. RESULTS: Periodontitis risk decreased by 3% for every 10-MET increase in average physical activity after adjustment for age, smoking, diabetes, BMI, alcohol consumption and total calories (RR = 0.97; 95% CI: 0.95-0.99). The inverse trend remained significant in the categorical analysis. Compared to men in the lowest quintile of physical activity, those in the highest quintile had a 13% lower risk of periodontitis (RR = 0.87; 95% CI: 0.76-1.01, p-value, test for trend = 0.02). In a sub-sample of men with radiographs (n = 137) the physically active had less average bone loss (beta = -0.29, p-value = 0.03) after multivariate adjustment compared to those inactive. CONCLUSIONS: In this large-scale prospective study, we found an inverse, linear association between sustained physical activity and periodontitis independent of known risk factors. The benefits of a physically active lifestyle may extend to periodontal health.

Leisure-time physical activity and reduced plasma levels of obesity-related inflammatory markers.

OBJECTIVE: This study investigated the relationship between physical activity and the obesity-related inflammatory markers C-reactive protein, interleukin-6, and soluble tumor necrosis factor receptors (sTNF-Rs) 1 and 2. Furthermore, we examined the relationship between physical activity and insulin sensitivity (insulin, C-peptide, and hemoglobin A(1c) levels) and whether inflammatory markers mediate this association. RESEARCH METHODS AND PROCEDURES: Biomarkers were measured in 405 healthy men and 454 healthy women from two large ongoing prospective studies. Information about physical activity and other variables was assessed by questionnaires. RESULTS: After adjustment for other predictors of inflammation, physical activity was inversely associated with plasma levels of sTNF-R1, sTNF-R2, interleukin-6, and C-reactive protein (p = 0.07, p = 0.004, p = 0.04, and p = 0.009). After further adjustment for BMI and leptin, as a surrogate for fat mass, most of these associations were no longer significant. Physical activity was also inversely related to insulin and C-peptide levels (p = 0.008 and p < 0.001); however, in contrast to BMI and leptin, levels of inflammatory markers explained only very little of this inverse relationship. DISCUSSION: These results suggest that frequent physical activity is associated with lower systemic inflammation and improved insulin sensitivity. These associations can partially be explained by a lower degree of obesity in physically active subjects. Although inflammatory markers may mediate obesity-dependent effects of physical activity on inflammatory related diseases such as type 2 diabetes or coronary heart disease, our study suggests that they do not directly account for the beneficial effects of physical activity on insulin resistance.

Whole grain consumption and weight gain: a review of the epidemiological evidence, potential mechanisms and opportunities for future research.

The epidemiological data that directly examine whole grain v. refined grain intake in relation to weight gain are sparse. However, recently reported studies offer insight into the potential role that whole grains may play in body-weight regulation due to the effects that the components of whole grains have on hormonal factors, satiety and satiation. In both clinical trials and observational studies the intake of whole-grain foods was inversely associated with plasma biomarkers of obesity, including insulin, C-peptide and leptin concentrations. Whole-grain foods tend to have low glycaemic index values, resulting in lower postprandial glucose responses and insulin demand. High insulin levels may promote obesity by altering adipose tissue physiology and by enhancing appetite. The fibre content of whole grains may also affect the secretion of gut hormones, independent of glycaemic response, that may act as satiety factors. Future studies may examine whether whole grain intake is directly related to body weight, and whether the associations are primarily driven by components of the grain, including dietary fibre, bran or germ.

Alcohol consumption patterns and HbA1c, C-peptide and insulin concentrations in men.

OBJECTIVE: Observational studies support inverse associations between moderate alcohol consumption and fasting insulin concentrations, but the importance of drinking pattern on the effect of alcohol on insulin sensitivity has not been fully explored. We examined the relations of alcohol consumption patterns-including average daily consumption, frequency of consumption and drinking with meals-to fasting insulin, fasting c-peptide and hemoglobin A1c (HbA1c). METHODS: A cross-sectional study of 462 disease-free men selected from the Health Professionals' Follow-up Study to provide information on a range of drinking patterns. Study participants were 48 to 82 years of age who provided a blood sample and detailed information on diet, life-style and alcohol consumption patterns in 1994. Among the study participants, 267 men provided a fasting blood sample and contributed to the analyses of insulin and c-peptide. RESULTS: Biologic markers were not strongly related to average alcohol consumption. Compared to abstainers, differences in insulin concentrations-all statistically non-significant-were 0.06, 1.25, 1.02, and 0.12 micro U/mL for consumers of <1, 1-1.9, 2-2.9, 3+ drinks per day, respectively. The frequency of alcohol consumption was inversely related to fasting c-peptide and insulin concentrations after controlling for average alcohol consumption and other potential confounding variables. Compared to men who reported consuming alcohol one to three days per week, c-peptide concentrations were 0.08 ng/mL and 0.29 ng/mL lower (p-trend = 0.04) in men who reported consuming alcohol on four to five days per week and six to seven days per week, respectively. Men who consumed alcohol on most days also had lower fasting insulin levels than more irregular drinkers (p-trend = 0.05). CONCLUSIONS: Our results suggest that frequent alcohol consumption is inversely related to fasting c-peptide and insulin concentrations.

Alcohol consumption in relation to risk of cholecystectomy in women.

BACKGROUND: Alcohol consumption has been linked to a lower risk of gallstone disease. However, the magnitude of the association is uncertain, and little is known about the relation of alcohol consumption patterns and individual types of alcoholic beverages to gallstone disease risk. OBJECTIVE: We prospectively examined the association between alcohol intake and cholecystectomy, a surrogate for symptomatic gallstone disease, in a large cohort of women. DESIGN: Women from the Nurses' Health Study who had no history of gallstone disease in 1980 (n = 80,898) were followed for 20 y. Alcohol consumption, which was measured every 2-4 y by food-frequency questionnaires, was used to predict subsequent cholecystectomy through multivariate analysis. RESULTS: We ascertained 7831 cases of cholecystectomy. Relative to subjects who had no alcohol intake, subjects who had alcohol intakes of 0.1-4.9, 5.0-14.9, 15.0-29.9, 30.0-49.9, and >/=50.0 g/d had multivariate relative risks of cholecystectomy of 0.95, 0.86, 0.80, 0.67, and 0.62 (95% CI: 0.49, 0.79), respectively. Relative to subjects who never consumed alcohol, subjects who consumed alcohol 1-2, 3-4, 5-6, and 7 d/wk had multivariate relative risks of cholecystectomy of 0.94, 0.88, 0.87, and 0.73 (0.63, 0.84), respectively. All alcoholic beverage types were inversely associated with cholecystectomy risk, independent of consumption patterns (for quantity of alcohol consumed, P = 0.04, 0.001, and 0.003 for wine, beer, and liquor, respectively; for frequency of alcohol consumption, P = 0.01, 0.07, and <0.0001 for wine, beer, and liquor, respectively). CONCLUSIONS: The intake of all alcoholic beverage types is inversely associated with the risk of cholecystectomy. Recommendations regarding the benefit of consuming moderate quantities of alcohol should be weighed against the potential health hazards.
