Predictiveness of body mass index for fatal coronary heart disease in men according to length of follow-up: a 21-year prospective cohort study.

Aims: To test the association between body mass index (BMI) and other coronary risk factors and the risk of a fatal coronary heart disease (CHD) event in different time periods during follow-up.

Methods: Prospective cohort study with a 21 year follow-up period. A screened sample of 14,403 men aged 40-49 years initially free of CHD.

Trends in the incidence of acute myocardial infarction and stroke: a 21-year follow-up of the Oslo study.

Objectives: To explore changes in the incidence of fatal and nonfatal myocardial infarction (MI) and stroke in the same male population over two decades.

Design: Men aged 40-49 born in the years 1923-1932 (N= 16,209) resident in Oslo participated in a cardiovascular screening programme in 1972-1973. Nonfatal cases of MI and stroke were obtained from hospital records and causes of death were ascertained by linkage to Statistics Norway.

Urban air pollution and mortality in a cohort of Norwegian men.

We investigated the association between total and cause-specific mortality and individual measures of long-term air pollution exposure in a cohort of Norwegian men followed from 1972-1973 through 1998. Data from a follow-up study on cardiovascular risk factors among 16,209 men 40-49 years of age living in Oslo, Norway, in 1972-1973 were linked with data from the Norwegian Death Register and with estimates of average yearly air pollution levels at the participants' home addresses from 1974 to 1998. Cox proportional-hazards regression was used to estimate associations between exposure and total and cause-specific mortality.

Lung cancer and air pollution: a 27 year follow up of 16 209 Norwegian men.

Background: The well documented urban/rural difference in lung cancer incidence and the detection of known carcinogens in the atmosphere have produced the hypothesis that long term air pollution may have an effect on lung cancer. The association between incidence of lung cancer and long term air pollution exposure was investigated in a cohort of Oslo men followed from 1972/73 to 1998.

Methods: Data from a follow up study on cardiovascular risk factors among 16 209 40 to 49 year old Oslo men in 1972/73 were linked to data from the Norwegian cancer register, the Norwegian death register, and estimates of average yearly air pollution levels at the participants' home address in 1974 to 1998.

Smoking habits and risk of fatal stroke: 18 years follow up of the Oslo Study.

Study Objective: To examine the risk of fatal stroke in relation to smoking habits in men screened for the Oslo study.

Design: The Oslo study is a prospective, cohort study of the epidemiology and preventive aspects of cardiovascular diseases in middle aged men. Screening started in May 1972 and results after 18 years of follow up are reported.
