Description

EPIDEMIOLOGICAL STUDIES SHOW a reduced risk of coronary heart disease (CHD) and all-cause mortality for individuals who consume alcohol in moderate amounts compared with individuals who consume very little alcohol and abstainers (Camargo et al., 1997; Corrao et al., 2000; Keil et al., 1997; Shaper et al., 1988). However, these results have been challenged as many studies on the CHD consequences of alcohol consumption suffer from epidemiological weaknesses, such as heterogeneity of the investigated exposed group or residual confounding. In a previous analysis of the KORA/MAGiC-Control study (KMC), we observed an association of various social, demographic, and behavioral factors as well as health conditions, with light alcohol consumption and abstinence (Konig et al., 2005). The fact that CHD risk factors are likely to confound studies that are designed to investigate the direct health effects of alcohol has also been shown impressively by data from a large population-based U.S. telephone survey. Of the 30 investigated cardiovascular disease-associated factors, 90% were significantly more prevalent among nondrinkers (assessed during the last 30 days) than among moderate drinkers (Naimi et al., 2005). Nondrinkers, assessed during a short period, are a heterogeneous group comprising occasional drinkers, nonlifetime abstainers (NLAs), and lifetime abstainers (LAs) (Konig et al., 2005; Wannamethee and Shaper, 1997). Cryer et al. (2001) analyzed data from a British health and lifestyle survey. Using a cluster analysis of sociodemographic and health status variables, both groups of 1,120 male and 2,683 female teetotalers were each divided into an optimum number of two alcohol-abstainer clusters. For each gender, one cluster reflected an LA group, containing, on average, younger and healthier individuals, who were also more likely to be working, whereas the other cluster reflected a "sick quitter" group, containing, on average, older participants with poorer health status, more disabled persons, and a greater proportion of exsmokers (Cryer et al., 2001).
