Moderate alcohol consumption improves insulin sensitivity in women

Research question:

A moderate alcohol consumption is associated with a reduced risk of getting type 2 diabetes, but this relationship is stronger for women than men. The reduced risk could be explained by diabetes by improving insulin sensitivity and glycemic status, but results in intervention studies of this relationship have been inconsistent. Therefore, this review article was performed?

Lowers drinking alcohol the risk of getting type 2 diabetes?

Study design:
This review article contained 14 intervention studies.

Results and conclusions:
The researchers found that drinking alcohol both insulin sensitivity [SMD = 0:06, 95% CI = -0.13 to 0:26] as the fasting glucose [SMD = 0:09, 95% CI = -0.09 to 0:27] did not significantly affect.

The researchers found that drinking alcohol both HbA1c [SMD = -0.62, 95% CI = -1.01 to -0.23, p = 0.002] and the fasting insulin levels [SMD = -0.17, 95% CI = -0.34 to 00:00, p = 0.049] significantly reduced.

The researchers found among women but not among men, drinking alcohol the fasting insulin levels [SMD = -0.23, 95% CI = -0.41 to -0.04, p = 0.019] and significantly reduced insulin sensitivity [SMD = 0.19, CI 955 = -0.03 to 00:41, p = 0.087] significantly improved.

The results were similar when only studies with moderate alcohol consumption were analyzed and the results were not affected by the dosage and duration of the intervention.

The researchers concluded that moderate alcohol consumption in women but not in men, the fasting insulin levels decreased and improved insulin sensitivity. These effects may provide an explanation for the relationship between alcohol consumption and type 2 diabetes. Moreover, moderate alcohol consumption can reduced HbA1c among both men and women.
