“…In 1972, 25 years after the first field investigation, a second follow-up was performed (Hagnell, 1990). In 1997, a 50-year follow-up was performed (Nettelbladt et al, 2005). Survivors of the total cohort, regardless of residence have been followed up in 1972 and in 1997.…”

The study commenced in 1947; the population was further investigated in 1957, 1972, and 1997.Methods: Experienced psychiatrists performed semi-structured diagnostic interviews, and best estimate consensus diagnoses of mental disorders were assessed at each field investigation.Subjects with mood disorder (n= 508, 195 males, 313 females) were identified until 1997.Causes and dates of death between 1947 and 2011 were obtained from the Swedish cause of death register and were compared between subjects diagnosed with mood disorder and other participants.Mortality was compared between those with mood disorders and the remaining cohort with Cox regression analyses. Other mental disorders were considered as risk factors for death for subjects with mood disorders. Results:The hazard ratio for mortality in mood disorders was HR=1.18. However, the mortality was elevated only for males, HR=1.5. A total of 6.3% of the participants with mood disorder and 1.2% of the remaining participants committed suicide. Comorbid anxiety disorders, organic disorders, dementia and psychotic disorders were significant risk factors for death.Conclusions: As expected, the suicide rate was higher among participants with mood disorders. Only males with mood disorders had elevated mortality. The impact on mortality from other mental disorders seems to vary between the genders.3

“…Since 1957, no additional participants have been included, but all participants from the two cohorts were assessed at followups regardless of where they lived. The second follow-up in 1972 assessed 2,827 survivors, while the third follow-up in 1997 assessed 1,797 survivors (Nettelbladt et al, 2005). The participants were asked about episodes of mental disorders including AUD during the whole study period including the intervals between the different follow-ups.…”

“…One part of the interview was structured to generate factual information about episodes of mental disorders. The other part was unstructured, but often provided additional, valuable information (Nettelbladt et al, 2005). The majority of the interviews took place in the participants' homes or place of employment, but 128 telephone interviews were performed in the 1997 field investigation, mainly due to distance.…”

Episodes of mental disorders (e.g., AUD) and sociodemographic variables were assessed, affording a unique opportunity to investigate the incidence of AUD and by age, gender and socio-demographic predictors.…”

Objective: Epidemiological evidence indicates an inverse relationship between socio-economic status (SES) and alcohol use disorder (AUD), although there are relatively few recent incidence studies. The present study aimed to assess the incidence of AUD by age, gender and SES and to analyse AUD's association with mental disorder.Method: Information about mental disorders, including first incidence cases of AUD, was assessed in the Lundby cohort (n=3,563) by field investigations in 1947, 1957, 1972 and 1997. Incidence calculations were based on 3,372 individuals without prior AUD. For the two genders, age-standardised incidences of AUD for the 25-year periods of 1947-1972 and 1972-1997 were compared. Possible risk factors for incident AUD were analysed by means of Cox regression analyses for the whole sample and for each sex separately.

“…They would not have known that their respondents were to be assessed a further three times over the next 50 years. In 1957 Hagnell re-examined 98% of the same people, irrespective of domicile, together with 1013 newcomers who had moved into the area [2]. In 1972 and again in 1997, the investigating team examined the survivors of the original 1957 cohort [3].…”

Abstract: Low attrition rates over 50 years and reasonable diagnostic uniformity make comparisons over time justifiable.
