BACKGROUND: The dose-response relationship of alcohol and injury and the effects of country-level detrimental drinking pattern (DDP) and alcohol control policy on this relationship is examined for specific causes of injury.
METHOD: The dose-response risk of injury is analyzed on 18,627 injured patients in 22 countries included in the International Collaborative Alcohol and Injury Study (ICAIS), using case-crossover analysis by cause of injury (traffic, violence, falls, other), DDP and the International Alcohol Policy and Injury Index (IAPII).
RESULTS: Risk of all injury was higher at all volume levels in higher DDP countries compared to lower DDP countries and for each cause of injury. Risk of injury from traffic was significantly greater in higher DDP than lower DDP countries at 3.1-6 drinks (OR=2.65, CI=1.17-5.97), and at ≤ 3 drinks for falls (OR=2.51, CI=1.52-4.16) and injuries from other causes (OR=1.72, CI=1.10-2.69). Countries with higher restrictive alcohol policy were at a lower risk of injury at lower levels of consumption (≤ 3 drinks) for all injuries (OR= 0.72, CI=0.56-0.92) and for injuries from other causes (OR=0.46, CI=0.29-0.73), and at a lower risk of traffic injuries at higher levels of consumption (≥ 10 drinks). At higher levels of consumption (≥ 10 drinks) countries with higher alcohol policy restrictiveness were at greater risk for all injuries (OR=2.03, CI=1.29-3.20) and those from violence (OR=9.02, CI=3.00-27.13) and falls (OR=4.29, CI=1.86-9.91).
CONCLUSIONS: Countries with high DDP are at higher risk of injury from most causes at a given level of consumption, while countries with low restrictiveness of alcohol policy are at higher risk of injury at lower levels of consumption and at higher risk of traffic injuries at high levels of consumption. These findings underscore the importance of aggregate-level factors which need to be considered in developing effective intervention and prevention strategies for reducing alcohol-related injury.
