Related factors with substance use in old adults

Abstract

Intro

Substance use disorder is a growing phenomenon among the elderly. It is undervalued, misidentified, underdiagnosed and poorly treated.

Aim

Study prevalence, characteristics and risk factors associated with drug use among the elderly.

Method

A 6-month prospective study of substance use in elderly patients (65+) who attended the addiction and dual diagnosis unit, Vall d’Hebron University Hospital.

Results

Fifty-nine patients evaluated, mean age 70.04 years, 60% men. A total of 49.1% are married, 35.8% divorced and 53.8% live with a partner and/or children. A total of 67.3% have basic studies and 78.8% are pensioners. A total of 82.7% have no criminal record.

Medical comorbidity presents in 90.4% of the sample, psychiatric and addictive family background in 42.3% and 37.3%. A total of 67.3% have comorbid Axis I (mainly affective disorders) and 25% Axis II (cluster B most). A total of 7.7% attempted suicide at least once.

The main substance is alcohol (76.9%), followed by prescription drugs (19.3%). A total of 28.8% are multi-drug users. A total of 67.3% have used tobacco in their life and 63.5% are currently dependent. The average age of onset for a disorder for any substance consumption is 28.19, being lower for alcohol and illegal substances and higher for prescription drugs.

A total of 61.5% have gone through treatment before but only 32.7% has been admitted because of addiction. The adherence rate is 90.4% and the relapse rate 8.3% at first month and 13% at 6 months.

Conclusions

Old adults present differences compared to overall drug user population: prevalence by gender is almost equal, lower Axis II, less multi-drug consumption and both dropout and relapse rate are drastically lower.
