Útdráttur:Background: This study examines whether alcohol-related hospitalization predicts survey non-response, and
evaluates whether this missing data result in biased estimates of the prevalence of hazardous alcohol use and
abstinence.
Methods: Registry data on alcohol-related hospitalizations during the preceding ten years were linked to two
representative surveys. Population data corresponding to the surveys were derived from the Stockholm County
registry. The alcohol-related hospitalization rates for survey responders were compared with the population data,
and corresponding rates for non-responders were based on the differences between the two estimates. The
proportions with hazardous alcohol use and abstinence were calculated separately for previously hospitalized and
non-hospitalized responders, and non-responders were assumed to be similar to responders in this respect.
Results: Persons with previous alcohol-related admissions were more likely currently to abstain from alcohol
(RR=1.58, p<.001) or to have hazardous alcohol use (RR=2.06, p<.001). Alternatively, they were more than twice as
likely to have become non-responders. Adjusting for this skewed non-response, i.e., the underrepresentation of
hazardous users and abstainers among the hospitalized, made little difference to the estimated rates of hazardous
use and abstinence in total. During the ten-year period 1.7% of the population were hospitalized.
Conclusions: Few people receive alcohol-related hospital care and it remains unclear whether this group’s
underrepresentation in surveys is generalizable to other groups, such as hazardous users. While people with severe
alcohol problems – i.e. a history of alcohol-related hospitalizations – are less likely to respond to population surveys,
this particular bias is not likely to alter prevalence estimates of hazardous use.
