The prevalence of potential alcohol-drug interactions in older adults.

OBJECTIVES: The aim of this study was to assess the possibility of clinically significant drug-alcohol interactions among home-dwelling older adults aged ≥ 65 years. DESIGN: This study was a cross-sectional assessment of a stratified random sample of 2100 elderly people (≥ 65 years) in Espoo, Finland. The response rate was 71.6% from the community-dwelling sample. The drugs were coded according to their Anatomical Therapeutic Chemical (ATC) classification index (ATC DDD 2012). Significant alcohol interactive (AI) drugs were examined according to the Swedish, Finnish, INteraction X-referencing (SFINX) interaction database, as well as concomitant use of central nervous system drugs, hypoglycaemics, and warfarin with alcohol. "At-risk alcohol users" were defined consuming > 7 drinks/week, or ≥ 5 drinks on a typical drinking day, or using ≥ 3 drinks several times/week, "moderate users" as consuming at least one drink/month, but less than 7 drinks/week, and "minimal/non-users" less than one drink/month. RESULTS: Of the total sample (n = 1395), 1142 respondents responded as using at least one drug. Of the drug users, 715 (62.6%) persons used alcohol. The mean number of medications was 4.2 (SD 2.5) among "at-risk users", 4.0 (SD 2.6) among "moderate users", and 5.4 (SD 3.4) among "minimal/non-users" (p < 0.001). The concomitant use of AI drugs was widespread. Among the "at-risk users", "moderate users", and "minimal/nonusers" 42.2%, 34.9%, and 52.7%, respectively, were on AI drugs (p < 0.001). One in 10 of "at-risk users" used warfarin, hypnotics/sedatives, or metformin. CONCLUSIONS: Use of AI drugs is common among older adults, and this increases the potential risks related to the use of alcohol.

Older adults' own reasoning for their alcohol consumption.

OBJECTIVE: The aim of the study was to investigate what the older adults themselves consider to be the reasons for their alcohol consumption. METHODS: The data were collected with a postal questionnaire from a random sample of 2100 elderly people (≥65 years) living in the medium-sized city of Espoo, Finland. The response rate was 71.6% from the community-dwelling sample. Altogether 868 persons responded that they use alcohol. Of them, 831 gave reasons for their drinking. We defined "at-risk users" as consuming >7 drinks per week, or ≥5 drinks on a typical drinking day, or using ≥3 drinks several times per week. RESULTS: Main reasons given for alcohol consumption were "having fun or celebration" (58.7%), "for social reasons" (54.2%), "using alcohol for medicinal purposes" (20.1%), and "with meals" (13.8%). Younger age groups reported more often than the older age groups that they use alcohol for "having fun or celebration" and "for social reasons." The older age groups used more often "alcohol for medicinal purposes". Men used alcohol more often than women "as pastime" or "as sauna drink". Those defined as "at-risk users" reported using alcohol because of "meaningless life," for "relieving depression," "relieving anxiety," and "relieving loneliness." CONCLUSIONS: Older adults have diverse alcohol consumption habits like people in other age groups. The oldest olds reported that they use alcohol for medicinal purposes. The "at-risk users" admit they use alcohol because of meaningless life, and relieving depression, anxiety, and loneliness.
