Antidepressant sales and the risk for alcohol-related and non-alcohol-related suicide in Finland--an individual-level population study.

ABSTRACT:

Objectives

A marked decline in suicide rates has co-occurred with increased antidepressant sales in several countries but the causal connection between the trends remains debated. Most previous studies have focused on overall suicide rates and neglected differential effects in population subgroups. Our objective was to investigate whether increasing sales of non-tricyclic antidepressants have reduced alcohol- and non-alcohol-related suicide risk in different population subgroups.

Methods

We followed a nationally representative sample of 950,158 Finnish adults in 1995-2007 for alcohol-related (n = 2,859) and non-alcohol-related (n = 8,632) suicides. We assessed suicide risk by gender and social group according to regional sales of non-tricyclic antidepressants, measured by sold doses per capita, prevalence of antidepressant users, and proportion of antidepressant users with doses reflecting minimally adequate treatment. Fixed-effects Poisson regression models controlled for regional differences and time trends that may influence suicide risk irrespective of antidepressant sales.

Results

The number of sold antidepressant doses per capita and the prevalence of antidepressant users were unrelated to male suicide risk. However, one percentage point increase in the proportion of antidepressant users receiving minimally adequate treatment reduced non-alcohol-related male suicide risk by one percent (relative risk 0.987, 95% confidence interval 0.976-0.998). This beneficial effect only emerged among men with high education, high income, and employment, among men without a partner, and men not owning their home. Alcohol-related suicides and female suicides were unrelated to all measures of antidepressant sales.

Conclusion

We found little evidence that increase in overall sales or in the prevalence of non-tricyclic antidepressant users would have caused the fall in suicide rates in Finland in 1995-2007. However, the rise in the proportion of antidepressant users receiving minimally adequate treatment, possibly due to enhanced treatment compliance, may have prevented non-alcohol-related suicides among men.

Project description:BackgroundSocial isolation and living alone are increasingly common in industrialised countries. However, few studies have investigated the potential public health implications of this trend. We estimated the relative risk of death from alcohol-related causes among individuals living alone and determined whether this risk changed after a large reduction in alcohol prices.Methods and findingsWe conducted a population-based natural experimental study of a change in the price of alcohol that occurred because of new laws enacted in Finland in January and March of 2004, utilising national registers. The data are based on an 11% sample of the Finnish population aged 15-79 y supplemented with an oversample of deaths. The oversample covered 80% of all deaths during the periods January 1, 2000-December 31, 2003 (the four years immediately before the price reduction of alcohol), and January 1, 2004-December 31, 2007 (the four years immediately after the price reduction). Alcohol-related mortality was defined using both underlying and contributory causes of death. During the 8-y follow-up about 18,200 persons died due to alcohol-related causes. Among married or cohabiting people the increase in alcohol-related mortality was small or non-existing between the periods 2000-2003 and 2004-2007, whereas for those living alone, this increase was substantial, especially in men and women aged 50-69 y. For liver disease in men, the most common fatal alcohol-related disease, the age-adjusted risk ratio associated with living alone was 3.7 (95% confidence interval 3.3, 4.1) before and 4.9 (95% CI 4.4, 5.4) after the price reduction (p<0.001 for difference in risk ratios). In women, the corresponding risk ratios were 1.7 (95% CI 1.4, 2.1) and 2.4 (95% CI 2.0, 2.9), respectively (p ? 0.01). Living alone was also associated with other mortality from alcohol-related diseases (range of risk ratios 2.3 to 8.0) as well as deaths from accidents and violence with alcohol as a contributing cause (risk ratios between 2.1 and 4.7), both before and after the price reduction.ConclusionsLiving alone is associated with a substantially increased risk of alcohol-related mortality, irrespective of gender, socioeconomic status, or the specific cause of death. The greater availability of alcohol in Finland after legislation-instituted price reductions in the first three months of 2004 increased in particular the relative excess in fatal liver disease among individuals living alone.

Project description:ObjectivesThe aim was to assess alcohol-related mortality of persons with mixed and uniform ethnic origins in two national contexts.SettingData were from the multigenerational population registers of the total population of Finland and Sweden observed from 1971 to 2017. Study persons were men and women of ethnic Finnish and Swedish background, born in their country of residence.ParticipantsPersons were born between 1953 and 1999. In Finland, ethnic origin was assessed through own, mother's and father's Finnish or Swedish ethnolinguistic affiliation. Data on Sweden included persons born in Sweden, with mother and father born in Sweden or Finland. A total of 2 997 867 and 4 148 794 persons were included in the Finnish and Swedish data, respectively. The total number of alcohol-related deaths by main cause was 13 204 and 3336. Cox regressions were used to examine associations.Outcome measuresFor the period 1971-2017, we studied alcohol as the main cause of death. For the period 1996-2017, we observed if alcohol was the main or contributing cause of death. Parallel analyses were performed for all-cause mortality.ResultsFor men in Finland, the hazard rate of alcohol-related mortality of Swedish speakers with uniform Swedish background was 0.44 (95% CI: 0.38 to 0.52) that of Finnish speakers with uniform Finnish background. The corresponding hazard rate for women was 0.40 (95% CI: 0.28 to 0.55). In Sweden, the hazard rate of men with both parents born in Sweden was 0.40 (95% CI: 0.32 to 0.49) that of men with both parents born in Finland. The corresponding hazard rate for women was 0.50 (95% CI: 0.31 to 0.79). In both countries, persons with mixed background had an alcohol-related mortality rate between that of persons with uniform Finnish and Swedish background.ConclusionThe consistent pattern across countries necessitates increased policy attention towards offspring disadvantaged via parental ethnicity to minimise harmful consequences of alcohol consumption across and within ethnic groups.
