We sought to identify a level of alcohol consumption representing the boundary between health protective and hazardous drinking. The Winnipeg Health and Drinking Survey began in 1990-91 (n = 1257). Seven years later, a third wave of interviews (n = 785) expanded questions on heavy episodic drinking (HED) and assessed the consumption of > or = 3, > or = 5, > or = 8, and > or = 12 drinks at a sitting for each of wine, beer and liquor (equivalent to about 40 g, 65 g, 105 g and 155 g of ethanol). Cox proportional hazards models were based on seven years of illness and mortality data following the Wave 3 interview, and were stratified by gender and HED definition. For HED of > or = 40 g, > or = 65 g, > or = 105 g, or > or = 155 g per occasion, the hazard ratios for morbidity and mortality from all causes were 1.06, 1.09, 1.17, and 1.16 respectively in women, and 1.00, 0.98, 1.02, and 1.02 in men. Most of these hazard ratios were significant in women, whereas none was significant in men. This study did not provide support for a definition of HED that could divide protective from hazardous alcohol consumption.

Studies have suggested that moderate alcohol consumption is associated with a reduced risk of CVD and premature mortality in individuals with diabetes mellitus. However, history of alcohol consumption has hardly been taken into account. We investigated the association between current alcohol consumption and mortality in men and women with diabetes mellitus accounting for past alcohol consumption. Within the European Prospective Investigation into Cancer and Nutrition (EPIC), a cohort was defined of 4797 participants with a confirmed diagnosis of diabetes mellitus. Men and women were assigned to categories of baseline and past alcohol consumption. Hazard ratios (HR) and 95 % CI for total mortality were estimated with multivariable Cox regression models, using light alcohol consumption (>0-6 g/d) as the reference category. Compared with light alcohol consumption, no relationship was observed between consumption of 6 g/d or more and total mortality. HR for >6-12 g/d was 0.89 (95 % CI 0.61, 1.30) in men and 0.86 (95 % CI 0.46, 1.60) in women. Adjustment for past alcohol consumption did not change the estimates substantially. In individuals who at baseline reported abstaining from alcohol, mortality rates were increased relative to light consumers: HR was 1.52 (95 % CI 0.99, 2.35) in men and 1.81 (95 % CI 1.04, 3.17) in women. The present study in diabetic individuals showed no association between current alcohol consumption >6 g/d and mortality risk compared with light consumption. The increased mortality risk among non-consumers appeared to be affected by their past alcohol consumption rather than their current abstinence.

BACKGROUND: Findings of past studies on the effect of drinking patterns on diabetes risk have been inconsistent. OBJECTIVE: We aimed to investigate the role of drinking frequency and usual quantity consumed in the development of type 2 diabetes. DESIGN: Enrolled were 1650 Japanese men without diabetes (diabetes: fasting plasma glucose >/=7.0 mmol/L, glycated hemoglobin >/=6.5%, or self-reported clinician-diagnosed diabetes). Average alcohol consumption and 12 combinations of frequency and usual quantity per drinking occasion were assessed at the baseline examination. The absolute risk and HR for the development of diabetes were calculated. RESULTS: During a mean follow-up period of 10.2 y, 216 individuals developed diabetes. Lifetime abstainers (n = 153) had a relatively low incidence of diabetes (9.1/1000 person-years), similar to moderate consumers (99-160 g ethanol/wk; 9.0/1000 person-years). Increasingly higher quantities of alcohol usually consumed per occasion increased the risk of diabetes regardless of drinking frequency. The lowest incidence rate of diabetes (8.5/1000 person-years) was associated with the consumption of /=6 times/wk. Binge drinking (>/=3 drinks per occasion) significantly increased the risk of future diabetes regardless of frequency (HR: 1.79; 95% CI: 1.17, 2.74) compared with

BACKGROUND: Numerous studies have reported inverse associations of coffee, tea, and alcohol intake with risk of type 2 diabetes, but none has reported results separately among African American women.

OBJECTIVE: We prospectively examined the relation of coffee, tea, and alcohol consumption to diabetes risk in African American women.

DESIGN: The study included 46,906 Black Women's Health Study participants aged 30-69 y at baseline in 1995. Dietary intake was assessed in 1995 and 2001 by using a validated food-frequency questionnaire. During 12 y of follow-up, there were 3671 incident cases of type 2 diabetes. Relative risks (RRs) and 95% CIs were estimated by using Cox proportional hazards models adjusted for diabetes risk factors.

RESULTS: Multivariable RRs for intakes of 0-1, 1, 2-3, and >/=4 cups of caffeinated coffee/d relative to no coffee intake were 0.94 (95% CI: 0.86, 1.04), 0.90 (95% CI: 0.81, 1.01), 0.82 (95% CI: 0.72, 0.93), and 0.83 (95% CI: 0.69, 1.01), respectively (P for trend = 0.003). Multivariable RRs for intakes of 1-3, 4-6, 7-13, and >/=14 alcoholic drinks/wk relative to never consumption were 0.90 (95% CI: 0.82, 1.00), 0.68 (95% CI: 0.57, 0.81), 0.78 (95% CI: 0.63, 0.96), and 0.72 (95% CI: 0.53, 0.98), respectively (P for trend < 0.0001). Intakes of decaffeinated coffee and tea were not associated with risk of diabetes.

CONCLUSION: Our results suggest that African American women who drink moderate amounts of caffeinated coffee or alcohol have a reduced risk of type 2 diabetes.
