Alcohol as a disease
Epidemiology is an eclectic discipline comprising facets of sociology, statistics, medicine, and demography. It is a branch of medical science that deals with the incidence, prevalence, and control of disease in a population and includes the study of factors that affect the progress of a disease.When we discuss the incidence of a disease we are concerned with the number of new cases within a specific time period. When we discuss the prevalence of a disease we are concerned with the total number of cases within a population. This module focuses on the epidemiology of alcohol use. We will examine population characteristics that are related to differences in alcohol consumption between groups of individuals such as gender, age, nationality, and ethnicity.

Or, is there some neurochemical difference in the brains of men and women that predisposes men to greater alcohol consumption? Thus, we should remember, that although epidemiologic studies can reveal important factors related to alcohol consumption, such data do not provide evidence of a causal relation. The survey includes a set of questions asking about the recent use and frequency of the consumption of alcoholic beverages, such as beer, wine, whiskey, brandy, and mixed drinks. SAMHSA conducts the National Survey on Drug Use and Health (NSDUH).
