[Changes in cardiovascular risk factors among men in Oslo during 28 years].

BACKGROUND: The aim of the study was to measure changes in known risk factors for cardiovascular disease among men over a period of 28 years. MATERIAL AND METHODS: The present cohort study comprises a selection of men previously included in the Oslo-study of 1972/73. The men selected, were either followed-up in the Oslo II study (n = 5,323), or were included in five other studies in the period 1996-2001 (n = 1,834). The total material is named The second screening of the Oslo-study and consists of 7157 men. RESULTS: The men were born between 1923 and 1952. All age groups showed a marked increase in mean weight by 4.4 Kg. Body Mass Index changed from 24.3 to 26.4 kg/m2 , coinciding with reduced level of physical activity in all age groups. A comparison of body mass index in men of the same age in 1972/73 and 2000, show a mean increase in body mass index of two units. An increase of 0.30 mmol/L glucose (non-fasting) was observed. Total cholesterol decreased from 6.19 to 5.95 mmol/L and triglycerides remained unchanged (1.89 to 1.87 mmol/L). Systolic blood pressure increased but not the diastolic pressure. Overall 30.8 % of the men took medication for increased blood pressure, versus 3.1 % at the first screening. The percentage of daily smokers decreased from 44.2 % to 17.4 %. INTERPRETATION: The most encouraging result was the strong reduction in number of daily smokers. The study confirms the weight increase observed among men in Norway.

[Is a healthy lifestyle worthwhile?].

BACKGROUND: The men invited to participate in the Oslo Study in 1972/3 were invited again to participate in the Oslo II study in 2000. We examined whether self-reported lifestyle habits were associated with biological markers, a range of symptoms and several illnesses in 2000. MATERIAL AND METHODS: In addition to data from Oslo II, were data from those men of the Oslo-cohort who participated in 5 other studies between 1998 and 2001. The total material is named The second screening of the Oslo-study. Levels of lipids and glucose, height, weight, waist and hip circumferences and blood pressure were measured in 6,410 men born in 1923-32 that participated in both surveys. Participants were divided into four groups according to their lifestyle habits in both surveys, as follows: unhealthy, somewhat unhealthy, somewhat healthy and healthy lifestyle. RESULTS: Participants with a healthy lifestyle had a lower number of symptoms and illnesses, prevalence of the metabolic syndrome and waist-hip ratio, compared to those with a less healthy lifestyle. The number of men with psychological distress leading to treatment, was inversely associated with an increasingly healthy lifestyle. After adjustment for level of education and smoking in both 1972/3 and in 2000, the relationship between health profile and lifestyle became more linear. INTERPRETATION: A healthy lifestyle was associated with protective levels of risk factors and lower prevalences of a wide range of illnesses.

Risk-factor profile for the incidence of subarachnoid and intracerebral haemorrhage, cerebral infarction, and unspecified stroke during 21 years' follow-up in men.

AIMS: To study the risk-factor profile for the incidence of non-fatal and fatal stroke among middle-aged men according to the stroke subtypes subarachnoid or intracerebral haemorrhage, cerebral infarction, and unspecified stroke. METHODS: The study design is a prospective cohort study. A total of 16,209 men aged 40-49 years resident in Oslo were screened for cardiovascular disease risk factors in 1972-73. Of these, 14,403 men had no cardiovascular symptoms or diseases or diabetes. The incidence of stroke after 21 years of follow-up of all men was extracted from hospital records and linkage to Statistics Norway. RESULTS: A total of 429 non-fatal and 107 fatal stroke events were registered. Case fatality within 28 days (number and percentage of cases) was 51% (41, 7.7%) for subarachnoid haemorrhage, 39% (67, 12.6%) for cerebral haemorrhage, 10% (246, 46.3%) for cerebral infarct, and 19% (177, 33.4%) for unspecified stroke. Risk of stroke (not subarachnoid haemorrhage) increased with the presence of symptoms or a history of cardiovascular disease or diabetes. In multivariate analysis of men without CVD or diabetes, high blood pressure was a risk factor for all subtypes of stroke; furthermore, daily smoking was a risk factor for all subtypes except subarachnoid haemorrhage. Serum cholesterol and glucose concentrations and height (inverse association) were independently associated with cerebral infarction. Smoking was a significantly stronger predictor of fatal than non-fatal events. CONCLUSIONS: The risk-factor profile differed according to the underlying subtype of stroke. Cerebral infarction clearly shared with myocardial infarction the classical risk factors, including non-fasting glucose concentration.

[External cephalic version of breech presentation at term].

BACKGROUND: External cephalic version could be an alternative to either vaginal delivery or caesarean section in breech presentation at term. MATERIAL AND METHODS: A systematic literature review about external cephalic version in breech presentation. RESULTS: The numbers of breech presentation delivered by caesarean section could probably be reduced in Norway by offering version, but this would not affect perinatal mortality.

Six years' experience with interdisciplinary review teams in health technology assessment in Norway.

OBJECTIVES: The aim of this study was to evaluate the use of interdisciplinary review teams that have been the main and central work form in making health technology assessments at the Norwegian Centre for Health Technology Assessment. METHODS: Evaluation questionnaires were sent to all 112 participants in the 17 review teams for the period of January 1998 to June 2003 after completion of the literature assessment. Questions were on the theme/mandate of the assessments, composition of the review team, organization of the work, the working method, and update of the report. RESULTS: The teams ranged from 4 to 14 persons regarded as opinion leaders in their field. The project periods lasted from 4 to 33 months. In all, fifty-five participants gave fifty-eight responses (51.8 percent) to the questionnaires. A total of 83 percent thought the theme was well argued, and 62 percent thought the mandate for the assessments was sufficiently clear. Approximately 80 percent were positive to the composition of the review team. In all, 22 percent expressed that the work method was too extensive and 43 percent wanted more tuition. General comments were that the working method gave competence in assessing medical literature, relevant professional training, and tuition in a working method that ensured the legitimacy of their work. CONCLUSIONS: The review team participants were satisfied with most aspects of the work. The Norwegian Centre for Health Technology Assessment will continue using interdisciplinary review teams in making health technology assessments.

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. The closing date was December 31, 1993. RESULTS: The cohort had a lower mortality rate than the general Norwegian population. First nonfatal and fatal MIs declined in each age and birth cohort during the entire follow-up. The incidence of nonfatal and fatal stroke decreased about 10 years after the initial screening. The risk of men with Rose questionnaire-based symptoms of angina or claudication was between that of healthy men and men with established cardiovascular disease or diabetes. CONCLUSIONS: There has been a reduction in both nonfatal and fatal incident cases of MI and stroke 10 years later indicating a pronounced change in all age groups and a lasting change throughout the period of follow-up. The Rose questionnaire predicted both future stroke and MI.

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. During the follow-up time 4,227 men died from a disease corresponding to an ICD-9 (International Classification of Diseases, Revision 9) code < 800. Controlling for a number of potential confounders, the adjusted risk ratio for dying was 1.08 [95% confidence interval (CI), 1.06-1.11] for a 10- microg/m3 increase in average exposure to nitrogen oxides (NOx) at the home address from 1974 through 1978. Corresponding adjusted risk ratios for dying from a respiratory disease other than lung cancer were 1.16 (95% CI, 1.06-1.26); from lung cancer, 1.11 (95% CI, 1.03-1.19); from ischemic heart diseases, 1.08 (95% CI, 1.03-1.12); and from cerebrovascular diseases, 1.04 (95% CI, 0.94-1.15). The findings indicate that urban air pollution may increase the risk of dying. The effect seemed to be strongest for deaths from respiratory diseases other than lung cancer.

Estimating residential air pollution exposure among citizens in Oslo 1974-1998 using a geographical information system.

Annual concentration fields of SO2 and NOx for the period 1974-1998 are calculated for a 22 x 18 km2-grid in Oslo. In a study of lung cancer and air pollution in Oslo, 16209 men living in Oslo have been followed from 1972/73 to 1998. This paper presents a method for estimating their annual residential air pollution exposure for SO2 and NOx. In the exposure assessment the National Population Register provided information on home addresses. Each participant was given an annual average air pollutant concentration outdoors of the address he lived the largest part of that year. Persons living close to streets with high traffic were given an additional concentration, and persons who moved outside Oslo were given a region value for each year. Due to regulations of the sulfur content in fuel oil and a general change of local heating systems to electricity or distant heating, the SO2-concentrations in Central Oslo were reduced during the period from about 60 microg m(-3) in 1974-75 to about 4 microg m(-3) in 1997-98. Due to the increasing traffic the NOx-concentrations have increased slowly, from about 40 microg m(-3) in 1974-84 to about 60 microg m(-3) in 1989. After the introduction of catalyst cars the concentrations were reduced to about 45 microg m(-3) in 1997-98.
