Social inclusion of clients treated for substance abuse in Sweden in the 1980s: A 27-year follow-up

AIM

To investigate social inclusion/exclusion in terms of criminality, substance abuse and participation in the labour market in clients treated for substance abuse in Sweden in the 1980s during a follow-up period of 27 years.

METHOD

SWEDATE data are used for background information on the clients. The data were collected through interviews with clients registered for treatment in 31 in-patient treatment units in 1982 and 1983. Data on labour market status, education and medication related to drugs were collected from public registers. The study population consisted of 1132 individuals, who were followed from the year after exiting from treatment (Year 1) until the end of the follow-up (December 2013).

RESULTS

Among those who survived, the women seem to have succeeded better in terms of social inclusion both at an aggregated level and when the individual pathways were followed during the follow-up period. When comparing pathways between adverse and non-adverse groups during the follow-up period the results show movements from being adverse to non-adverse but also the opposite. In the last follow-up in 2013, the majority of the clients defined as non-adverse for the last nine years were in some way established in the labour market (including studies). In total, about two fifths of the group were in some way established in the labour market.

CONCLUSIONS

The fairly high proportion of clients moving between being adverse and non-adverse during the follow-up might support the perspective suggesting that dependence should not be considered as chronic.

Social and economic consequences of alcohol use disorder: a longitudinal cohort and co-relative analysis

BACKGROUND

Although alcohol use disorder (AUD) is associated with future risk for psychosocial dysfunction, the degree to which this arises from a direct causal effect of AUD on functioning v. from correlated risk factors (also known as confounders) is less clearly established.

METHOD

AUD was assessed from Swedish medical, criminal and pharmacy registries. In a large general population cohort, using Cox proportional hazard and regression models, we predicted from the onset of AUD four outcomes: early retirement, unemployment, social assistance, and individual income. We then examined the degree to which these associations were attenuated by relevant confounders as well as by the use of discordant cousin, half-sibling, full-sibling, and monozygotic twin pairs.

RESULTS

In males, AUD most strongly predicted social assistance [hazard ratio (HR) 8.27, 95% confidence interval (CI) 7.96-8.59], followed by early retirement (HR 5.63, 95% CI 5.53-5.72) and unemployment (HR 2.75, 95% CI 2.65-2.85). For income at age 50, AUD was associated with a decrease in income of 0.24 s.d.s (95% CI -0.25 to -0.23). Results were similar in females. Modest to moderate attenuation of these associations was seen in both sexes after the addition of relevant covariates. These associations were reduced but remained robust in discordant co-relative pairs, including monozygotic twins.

CONCLUSIONS

Our results suggest that AUD has a causal impact on a range of measures reflective of psychosocial dysfunction. These findings provide strong support for the drift hypothesis. However, some of the associations between AUD and dysfunction appear to be non-causal and result from shared risk factors, many of which are likely familial.
