The new study, Iso and (colleagues) say, shows that high levels of social support may enhance the heart- healthy effects of light to moderate alcohol consumption. Iso's team examined drinking patterns, social support and (cardiovascular health) of 19,356 men in their 40s, 50s and 60s who were enrolled in the Japan Public Health Center-based (Prospective) Study. Their alcohol consumption was classified into seven (categories): never, past, occasional, 1 to 149, 150 to 299, 300 to 449, or 450 or more grams of alcohol per week. During an average follow up of more than 9 years, 629 strokes and 207 (coronary heart diseases) were (documented) in the men. Confirming past studies, heavier drinking (i.e., 300 grams per week or more)was (associated with) an increased risk of stroke. This may be explained at least partly by (alcohol-induced) high blood pressure, the researchers say.
