The latest causal relationships are those between harmful drinking and incidence of infectious diseases such as tuberculosis as well as the course of HIV/AIDS. Alcohol consumption by an expectant mother may cause fetal alcohol syndrome and pre-term birth complications.
Factors affecting alcohol consumption and alcohol-related harm
A variety of factors have been identified at the individual and the societal level, which affect the levels and patterns of alcohol consumption and the magnitude of alcohol-related problems in populations.
Environmental factors include economic development, culture, availability of alcohol, and the comprehensiveness and levels of implementation and enforcement of alcohol policies. For a given level or pattern of drinking, vulnerabilities within a society are likely to have similar differential effects as those between societies. Although there is no single risk factor that is dominant, the more vulnerabilities a person has, the more likely the person is to develop alcohol-related problems as a result of alcohol consumption.
Conceptual causal model of alcohol consumption and health outcomes
Figure 1: Conceptual causal model of alcohol consumption and health outcomes
The impact of alcohol consumption on chronic and acute health outcomes in populations is largely determined by 2 separate but related dimensions of drinking:
the total volume of alcohol consumed, and
the pattern of drinking.
The context of drinking plays an important role in occurrence of alcohol-related harm, particularly associated with health effects of alcohol intoxication, and, on rare occasions, also the quality of alcohol consumed. Alcohol consumption can have an impact not only on the incidence of diseases, injuries and other health conditions, but also on the course of disorders and their outcomes in individuals.
There are gender differences in alcohol-related mortality, morbidity, as well as levels and patterns of alcohol consumption. The percentage of alcohol-attributable deaths among men amount to 7.6 % of all global deaths compared to 4.0 % of all
