Risk factors for disability pension in a population-based cohort of men and women on long-term sick leave in Sweden.

Background: Knowledge on predictors of disability pension is very limited. The aim was to assess the importance of sick-leave diagnosis and socio-demographic variables as risk factors for disability pension among individuals on long-term sickness absence and to compare these factors by gender and over time.

Methods: A prospective population-based cohort study in Ostergötland County, Sweden, included 19,379 individuals who, in 1985-87, were aged 16-60 years and had a new spell of long-term sickness absence lasting > or =56 days.

Age and gender differences in the impact of diabetes on the prevalence of ischemic heart disease: a population-based register study.

Objective: To explore age and gender differences in the impact of diabetes on the prevalence of ischemic heart disease (IHD) in a defined population.

Methods: Data were obtained from an administrative health care register covering a population of about 415,000. The study included all patients aged 45-74 years diagnosed between 1999 and 2003 with IHD (n=11,311) and diabetes (n=10,364) by physicians at all primary health care centres (PHCs) and out- and inpatient clinics at all hospitals in the county of Ostergötland, Sweden.

Estimating disease prevalence using a population-based administrative healthcare database.

Aims: In Ostergötland County, Sweden, all data on hospital care and primary healthcare (PHC) have been entered in a diagnosis-related administrative database since 1999. This database was used to estimate the prevalence of four chronic diseases and to examine the capture of data in PHC, outpatient hospital care, and inpatient hospital care, considered in different time frames.

Methods: A case-finding algorithm identified patients with at least one healthcare contact involving a diagnosis of diabetes, hypertension, asthma, or chronic obstructive pulmonary disease (COPD) in 1999-2003.

Mortality in relation to disability pension: findings from a 12-year prospective population-based cohort study in Sweden.

Aims: Knowledge is limited regarding the association between disability pension (DP) and mortality. The aim of this study was to examine the relative risk (RR) of mortality associated with DP among women and men of different ages over a 12-year period, for DP in general, and for full-time DP, part-time DP, and DP for labour-market reasons, respectively.

Methods: A prospective cohort study was performed covering the total population of the Swedish county of Ostergötland aged 16-64 years in December 1984 (n = 245,704) followed up from 1985 to 1996.
