BACKGROUND AND AIMS: We prospectively assessed the association between a healthy lifestyle score (HLS) and the risk of type 2 diabetes mellitus (T2DM) in a Mediterranean cohort.

METHODS AND RESULTS: We followed up 11,005 participants initially free of diabetes diagnosis in the "Seguimiento Universidad de Navarra" (SUN) cohort. We evaluated the influence of lifestyle-related factors based on a score previously related to a lower risk of cardiovascular disease. Only one incident case of T2DM was found among those with a baseline BMI 22 kg/m(2). We measured the baseline adherence of a HLS that included: never smoking, physical activity, Mediterranean diet adherence, moderate alcohol consumption, avoidance of binge drinking, low television exposure, taking a short nap, spending time with friends and working hours. Incident cases of T2DM were self-reported by participants and confirmed by a physician. Cox proportional-hazards regression models were fitted to assess the association between HLS and the incidence of T2DM. After a median follow-up of 12 years, 145 incident cases of T2DM were observed. Among participants with a BMI >22 kg/m(2), the highest category of HLS adherence (7-9 points) showed a significant 46% relatively decreased hazard of T2DM compared with the lowest category (0-4 points) (multivariable adjusted HR: 0.54; 95% CI: 0.30-0.99).

CONCLUSIONS: Higher adherence to a HLS, including some factors not typically studied, may reduce T2DM risk. Preventive efforts should preferentially focus on weight control. However, this score may promote a comprehensive approach to diabetes prevention beyond weight reduction.

Health benefits of moderate wine consumption have been studied during the past decades, first in observational studies and more recently, in experimental settings and randomized controlled studies. Suggested biological pathways include antioxidant, lipid regulating, and anti-inflammatory effects. Both the alcoholic and polyphenolic components of wine are believed to contribute to these beneficial effects.

Although several of these studies demonstrated protective associations between moderate drinking and cardiovascular disease, atherosclerosis, hypertension, certain types of cancer, type 2 diabetes, neurological disorders, and the metabolic syndrome, no conclusive recommendations exist regarding moderate wine consumption. Yet, it is suggested that the physician and patient should discuss alcohol use. In the CASCADE (CArdiovaSCulAr Diabetes & Ethanol) trial, 224 abstainers with type 2 diabetes were randomized to consume red wine, white wine or mineral water for two years.

Here, we summarize our previous findings, offer new evidence concerning the differential effects of wine consumption among men and women, and further suggest that initiating moderate alcohol consumption among well-controlled persons with type 2 diabetes is apparently safe, in regard to changes in heart rate variability and carotid plaque formation

BACKGROUND: Previous cohort studies have shown that moderate alcohol consumption was associated with a lower risk of type 2 diabetes (T2D). However, whether these associations differ according to the characteristics of patients with T2D remains controversial.

OBJECTIVE: The purpose of this study was to explore and summarize the evidence on the strength of the association between alcohol consumption and the subsequent risk of T2D by using a dose-response meta-analytic approach.

DESIGN: We identified potential studies by searching the PubMed, Embase, and Cochrane Library databases up to 24 March 2015. Prospective observational studies that evaluated the relation between alcohol consumption and the risk of T2D and reported its effect estimates with 95% CIs were included.

RESULTS: Analyses were based on 706,716 individuals (275,711 men and 431,005 women) from 26 studies with 31,621 T2D cases. We detected a nonlinear relation between alcohol consumption and the risk of T2D, which was identified in all cohorts (P-trend < 0.001, P-nonlinearity < 0.001), in men (P-trend < 0.001, P-nonlinearity < 0.001), and in women (P-trend < 0.001, P-nonlinearity < 0.001). Compared with the minimal category of alcohol consumption, light (RR: 0.83; 95% CI: 0.73, 0.95; P = 0.005) and moderate (RR: 0.74; 95% CI: 0.67, 0.82; P < 0.001) alcohol consumption was associated with a lower risk of T2D. However, heavy alcohol consumption had little or no effect on subsequent T2D risk. Furthermore, the summary RR ratio (RRR; male to female) of the comparison between moderate alcohol consumption and the minimal alcohol categories for T2D was significantly higher, and the pooled RRR (current smoker to never smoker) of light alcohol consumption was significantly reduced.

CONCLUSIONS: Light and moderate alcohol consumption was associated with a lower risk of T2D, whereas heavy alcohol consumption was not related to the risk of T2D

AIMS/INTRODUCTION: Previous meta-analyses identified an inverse association of total alcohol consumption with the risk of type 2 diabetes. The current study further explored the relationship between specific types of alcoholic beverage and the incidence of type 2 diabetes.

MATERIALS AND METHODS: A search of PubMed, Embase and Cochrane Library databases from January 1966 to February 2016 was carried out for prospective cohort studies that assessed the effects of specific types of alcoholic beverage on the risk of type 2 diabetes. The pooled relative risks with 95% confidence interval were calculated using random- or fixed-effect models when appropriate.

RESULTS: A total of 13 prospective studies were included in this meta-analysis, with 397,296 study participants and 20,641 cases of type 2 diabetes. Relative to no or rare alcohol consumption, wine consumption was associated with a significant reduction of the risk of type 2 diabetes, with the pooled relative risks of 0.85, whereas beer or spirits consumption led to a slight trend of decreasing risk of type 2 diabetes (relative risk 0.96, 0.95, respectively). Further dose-response analysis showed a U-shaped relationship between all three alcohol types and type 2 diabetes. Additionally, the peak risk reduction emerged at 20-30 g/day for wine and beer, and at 7-15 g/day for spirits, with a decrease of 20, 9 and 5%, respectively.

CONCLUSIONS: Compared with beer or spirits, wine was associated with a more significant decreased risk of type 2 diabetes. The present study showed that wine might be more helpful for protection against type 2 diabetes than beer or spirits
