The problem with abdominal obesity is the accumulation of visceraladipose tissue, which is an important risk factor for cardiovascular disease. Alcohol haseffects on metabolism, and can also lead to an increase in total energy intake; these twofactors can lead to an increase in accumulation of visceral fat. Besides this there are studiesthat show that a moderate alcohol intake could be good for your health. The context gets morecomplicated since different studies have shown contradictory results concerning theassociation between alcohol, different types of alcoholic beverages and measurements ofabdominal fat.Objective: The objective of this article review is to assess the evidence of whether alcoholintake is associated with accumulation of visceral adipose tissue, using the measurementswaist circumference (WC) and waist-hip ratio (WHR).Search strategy: The databases used in the literature study were PubMed and Scopus. Thesearch strings were ?(spirits OR beer OR wine) AND (waist circumference OR waist hipratio)? and ?alcohol drinking pattern AND (waist circumference OR waist hip ratio)?.Selection criteria: Studies which investigated alcohol intake and WC or WHR and also madeadjustments for confounders were included.Data collection and analysis: Five studies matched the inclusion criteria. They were allestimated to be of low study quality. The conclusions were graded according to GRADE onthe endpoints of WC and WHR.Main results: Positive linear or j-shaped correlations between alcohol and WC and/or WHRwere seen in four of the five studies. Considering type of alcoholic beverage, the results wereheterogeneous.Conclusions: As of today there is no evidence for making changes in the Nordic NutritionRecommendations concerning alcohol. The scientific basis is insufficient and more researchin this area is needed.
