    Harm/Causation/Etiology Population (patient) Who was studied? Intervention (exposure, risk factor) - Which

    main exposure/risk factor am I considering? Comparison - What is the main alternative

    to compare with the exposure?

    Outcome - How is the incidence orprevalence of the condition in this groupaffected by this exposure?

    Majority of Reports

    to date have shownevidencesupporting apotential protectiveeffect of alcoholconsumption onCHD disease

    Most studieshave focused onthe amount of

    alcoholconsumed

    However, fewstudies haveaddressed thepattern of alcoholuse.

    Cases 427 white menDischarged alive with a diagnosis of incident MI

    55% of identified and eligible cases

    Interviewed and physical examinationQueried about a number of drinking habits Reference period: 12-24 months prior to MI

    Queried about a number of life-style habits:Smoking habits, physical activity, dietary

    Habits, personal medical history

    Interview Questions on Use of Alcoholic Beverages Size of container used and amount of alcoholic

    beverage usually consumed

    On a typical 28 day period as framework

    quantity-frequency questions on alcohol drinkingasked for Fridays, Saturdays, Sundays andweekdays

    Addressed proportion of drinking that took place

    with a meal Responses to questions used to compute 7

    variables for analyses

    Life-time abstainers

    Non-current drinkers

    Current drinkers non daily drinkers, dailydrinkers

    Ounces of ethanol consumed in 12 months

    Ounces of ethanol consumed in a drinking day

    Pattern of drinking in relation to food consumption with meals, with snacks, no food, with a mixedpattern

    Weekly drinking pattern less than weeklydrinkers, weekly non-daily drinkers, all week

    drinkers

    Methods Intervention-Comparison

    Two sets of analyses used:a. All participants were included; life-time

    abstainers were reference category

    b. Only participants who were currentdrinkers included; reference categoriesvary according to the specific drinkingpattern analysis enabled adjustment for

    amount of alcohol consumed

    Alcohol consumption isassociated with lower risk of

    non-fatal myocardialinfarction compared to life-time abstinence

    Infrequent drinkers have lower MI risk than life-time abstainers.

    Weekend drinkers do not differ significantly fromlife-time abstainers with regard to MI risk.

    Weekend drinkers have significantly higher risksof MI compared to less than weekly drinkers ordrinkers throughout the week

    Drinkers with meals or snacks have

    lower MI risk than either life-timeabstainers or participants who drank

    without food

    Alcohol affects men and womendifferently. Women become more

    impaired than men from drinking thesame amount of alcohol.

    Are generally smaller in size

    Have less body water

    Have less dehydrogenase(Dehydrogenase is an enzyme in the stomach that breaks down alcohol.)

    Have more estrogen

    The way in which alcohol is consumed may affect

    cardiovascular health. Consuming alcoholic beverages in a concentrated

    fashion (weekend only) and without food maycounteract any potential benefit of alcohol on thecardiovascular system

    Findings need to be further explored because itmay have implications for the kind of advicegiven both to patients and to the population atlarge with regard to drinking habits and theirrelationship with health
