Diagnostic tests and treatment procedures performed prior to cardiovascular death in individuals with severe mental illness.

OBJECTIVE: To examine whether severe mental illnesses (i.e., schizophrenia or bipolar disorder) affected diagnostic testing and treatment for cardiovascular diseases in primary and specialized health care. METHODS: We performed a nationwide study of 72 385 individuals who died from cardiovascular disease, of whom 1487 had been diagnosed with severe mental illnesses. Log-binomial regression analysis was applied to study the impact of severe mental illnesses on the uptake of diagnostic tests (e.g., 24-h blood pressure, glucose/HbA1c measurements, electrocardiography, echocardiography, coronary angiography, and ultrasound of peripheral vessels) and invasive cardiovascular treatments (i.e., revascularization, arrhythmia treatment, and vascular surgery). RESULTS: Patients with and without severe mental illnesses had similar prevalences of cardiovascular diagnostic tests performed in primary care, but patients with schizophrenia had lower prevalences of specialized cardiovascular examinations (prevalence ratio (PR) 0.78; 95% CI 0.73-0.85). Subjects with severe mental illnesses had lower prevalences of invasive cardiovascular treatments (schizophrenia, PR 0.58; 95% CI 0.49-0.70, bipolar disorder, PR 0.78; 95% CI 0.66-0.92). The prevalence of invasive cardiovascular treatments was similar in patients with and without severe mental illnesses when cardiovascular disease was diagnosed before death. CONCLUSION: Better access to specialized cardiovascular examinations is important to ensure equal cardiovascular treatments among individuals with severe mental illnesses.

Undiagnosed cardiovascular disease prior to cardiovascular death in individuals with severe mental illness.

OBJECTIVE: To examine whether individuals with schizophrenia (SCZ) or bipolar disorder (BD) had equal likelihood of not being diagnosed with cardiovascular disease (CVD) prior to cardiovascular death, compared to individuals without SCZ or BD. METHODS: Multivariate logistic regression analysis including nationwide data of 72 451 cardiovascular deaths in the years 2011-2016. Of these, 814 had a SCZ diagnosis and 673 a BD diagnosis in primary or specialist health care. RESULTS: Individuals with SCZ were 66% more likely (OR: 1.66; 95% CI: 1.39-1.98), women with BD were 38% more likely (adjusted OR: 1.38; 95% CI: 1.04-1.82), and men with BD were equally likely (OR: 0.88, 95% CI: 0.63-1.24) not to be diagnosed with CVD prior to cardiovascular death, compared to individuals without SMI. Almost all (98%) individuals with SMI and undiagnosed CVD had visited primary or specialized somatic health care prior to death, compared to 88% among the other individuals who died of CVD. CONCLUSION: Individuals with SCZ and women with BD are more likely to die due to undiagnosed CVD, despite increased risk of CVD and many contacts with primary and specialized somatic care. Strengthened efforts to prevent, recognize, and treat CVD in individuals with SMI from young age are needed.

Atrial fibrillation is associated with cognitive decline in stroke-free subjects: the Tromsø Study.

BACKGROUND AND PURPOSE: Previous studies have shown associations between atrial fibrillation (AF) and cognitive decline. We investigated this association in a prospective population study, focusing on whether stroke risk factors modulated this association in stroke-free women and men. METHODS: We included 4983 participants (57% women) from the fifth survey of the Tromsø Study (Tromsø 5, 2001), of whom 2491 also participated in the sixth survey (Tromsø 6, 2007-2008). Information about age, education, blood pressure, body mass index, lipids, smoking, coffee consumption, physical activity, depression, coronary and valvular heart disease, heart failure and diabetes was obtained at baseline. AF status was based on hospital records. The outcome was change in cognitive score from Tromsø 5 to Tromsø 6, measured by the verbal memory test, the digit-symbol coding test and the tapping test. RESULTS: Mean age at baseline was 65.4 years. The mean reduction in the tapping test scores was significantly larger in participants with AF (5.3 taps/10 s; 95% CI: 3.9, 6.7) compared with those without AF (3.8 taps/10 s; 95% CI: 3.5, 4.1). These estimates were unchanged when adjusted for other risk factors and were similar for both sexes. AF was not associated with change in the digit-symbol coding or the verbal memory tests. CONCLUSION: Atrial fibrillation in stroke-free participants was independently associated with cognitive decline as measured with the tapping test.

Carotid atherosclerosis and relation to growth of infrarenal aortic diameter and follow-up diameter: the Tromsø Study.

OBJECTIVES: This research aims to study how carotid atherosclerosis is related to growth of infrarenal aortic diameter and aneurysmal formation. DESIGN: Population-based follow-up study. MATERIALS AND METHODS: At baseline, ultrasound examination of the carotid artery and the abdominal aorta was performed in 4241 persons from a general population with no evidence of abdominal aortic aneurysm (AAA). The burden of atherosclerosis was assessed as carotid total plaque area (TPA). After a mean follow-up of 6.3 years, a new ultrasound examination was performed and measurements of the aortic diameter and carotid TPA were repeated. The effects on aortic diameter progression, follow-up diameter and risk for AAA were assessed in multiple linear and logistic regression models according to carotid TPA, adjusted for known risk factors. RESULTS: When analysing AAA as a dichotomous variable, a borderline association between atherosclerosis and AAA could be demonstrated. When modelling aortic diameter as a continuous variable, a 1-SD increase in 5 years' carotid plaque area (ΔTPA) was associated with a 0.12-mm growth in infrarenal aortic diameter (standard error (SE) 0.04) and a 0.20-mm wider aorta at follow-up (SE 0.06). No independent relation was seen for baseline atherosclerosis. CONCLUSIONS: Carotid plaque progression was positively related to growth in infrarenal aortic diameter and aortic diameter at follow-up. Whether this co-variation between plaque growth and aortic diameter growth is causally related or independent events is still an open question.

Smoking is a strong risk factor for non-vertebral fractures in women with diabetes: the Tromsø Study.

UNLABELLED: In this longitudinal study of 4,160 postmenopausal women (3,947 without and 213 with self-reported diabetes), smoking was strongly related to fracture risk in those with diabetes. INTRODUCTION: Smoking is related to low bone mass and increased risk of fracture risk in postmenopausal women of the general population. The aim of the present longitudinal population-based study was to examine the effect of smoking on the risk of non-vertebral fractures in women ≥ 55 years of age, with specific focus on its relationship with diabetes. METHODS: A total of 4,160 women (3,947 without and 213 with self-reported diabetes) from the municipality of Tromsø, Norway, were followed for a mean of 7.6 years. Measurements of height and weight and questionnaire information concerning smoking and alcohol consumption habits, physical activity, prevalent diseases, and use of medication were collected before the start of follow-up. Non-vertebral fractures were registered during follow-up. RESULTS: A total of 1,015 without and 66 with diabetes sustained a new non-vertebral fracture. Smoking status (never, past, and current) was significantly associated with an increased risk of fracture both in women with and without diabetes (p values for trend 0.02 and <0.001, respectively, after adjustments for age), but in women without diabetes, the relationship was no longer significant after multiple adjustments. There was a strong interaction between smoking status and diabetes on fracture risk (p= 0.004). Women with diabetes who were current smokers had a 3.47 (95% CI 1.82-6.62) higher risk of non-vertebral fractures than diabetic women who were never smokers (p value for linear trend = 0.001, after multiple adjustments). CONCLUSION: We conclude that smoking is strongly related to fracture risk in postmenopausal women with self-reported diabetes.

BMI change is associated with fracture incidence, but only in non-smokers. The Tromsø Study.

UNLABELLED: Few studies have examined the association between body mass index (BMI) change and fracture in a general population. We observed that BMI loss was associated with increased fracture risk in non-smoking men and women, but not in smokers. BMI gain was associated with decreased fracture risk in women. INTRODUCTION: Weight loss has been associated with increased fracture risk, but few studies have included men. The aim of this study was to examine the association between BMI change and fracture risk in both genders. METHODS: A population-based cohort study in Tromsø, Norway, of adults, aged 20 to 54 years in 1979, who participated in two or three health surveys in 1979-1980, 1986-1987, and 1994-1995. Weight and height were measured at each survey. Information about lifestyle was obtained by questionnaires. Poisson regression was used to estimate incidence rates and Cox proportional hazards regression model to assess the association between fracture risk and BMI change. Fractional polynomials were used to accommodate non-linear associations. RESULTS: A total of 5,549 men and 5,428 women participated. There were 1,135 fractures during 10 years of follow-up. Reduction in BMI was associated with increased non-vertebral fracture risk in non-smokers, but not in smokers. The hazard ratio in male and female non-smokers per 10-year BMI decrease of 2 kg/m(2) versus a BMI increase of 1 kg/m(2) was 1.79 (95% confidence interval (CI), 1.17-2.75) and 1.60 (95% CI, 1.28-1.99), respectively. The association was not significantly modified by initial BMI or age or by exclusion of subjects with cardiovascular diseases, diabetes, or cancer. In female non-smokers, weight gain was inversely associated with fracture risk. CONCLUSIONS: In a general Norwegian population, reduction in BMI was significantly associated with increased fracture risk in male and female non-smokers, but not in smokers. These findings could not be explained by preexisting disease.

Hip fractures in a city in Northern Norway over 15 years: time trends, seasonal variation and mortality : the Harstad Injury Prevention Study.

UNLABELLED: In this open population-based study from Northern Norway, there was no increase in hip fracture incidence in women and men from 1994 to 2008. Age-adjusted hip fracture rates was lower compared to reported rates from the Norwegian capital Oslo, indicating regional differences within the country. INTRODUCTION: The aim of the present population-based study was to describe age- and sex-specific incidence of hip fractures in a Northern Norwegian city, compare rates with the Norwegian capital Oslo, describe time trends in hip fracture incidence, place of injury, seasonal variation and compare mortality after hip fracture between women and men. METHODS: Data on hip fractures from 1994 to 2008 in women and men aged 50 years and above were obtained from the Harstad Injury Registry. RESULTS: There were altogether 603 hip fractures in Harstad between 1994 and 2008. The annual incidenc rose exponentially from 5.8 to 349.2 per 10,000 in men, and from 8.7 to 582.2 per 10,000 in women from the age group 50-54 to 90+ years. The age-adjusted incidence rates were 101.0 and 37.4 in women and men, respectively, compared to 118.0 in women (p = 0.005) and 44.0 in men (p = 0.09) in Oslo. The age-adjusted incidence rates did not increase between 1994-1996 and 2006-2008. The majority of hip fractures occurred indoors and seasonal variation was significant in fractures occurring outdoors only. After adjusting for age at hip fracture, mortality after fracture was higher in men than in women 3, 6 and 12 months (p ≤ 0.002) after fracture. CONCLUSIONS: There are regional differences in hip fracture incidence that cannot be explained by a north-south gradient in Norway. Preventive strategies must be targeted to indoor areas throughout the year and to outdoor areas in winter.

Anemia and the risk of non-vertebral fractures: the Tromsø Study.

UNLABELLED: In this longitudinal study of 5,286 persons, men with anemia had a 2.15 higher risk of non-vertebral fractures than men with high hemoglobin levels. Women with anemia had no increased fracture risk. INTRODUCTION: Low hemoglobin levels are associated with several risk factors for fractures such as low physical function, impaired cognition, and low bone mass. The aim of this population-based, prospective study was to examine whether anemia predicts non-vertebral fractures. METHODS: A total of 5,286 inhabitants from the municipality of Tromsø, Norway (2,511 men and 2,775 women), 55-74 years old at baseline, were followed for mean 8.3 years. Measurements of hemoglobin, mean corpuscular volume, height, weight, blood pressure, blood lipids, serum creatinine, and bone mineral density and questionnaire information concerning smoking and drinking habits, physical activity, prevalent diseases, and use of medication was collected before start of follow-up. Non-vertebral fractures were registered during follow-up. RESULTS: A total of 235 men and 641 women sustained a new non-vertebral fracture. One SD lower value of hemoglobin was associated with a 1.27 higher risk of fracture in men (p < 0.001, after multiple adjustments) and 1.08 (p = 0.07) in women. Men with anemia (hemoglobin levels <13 g/dL) had a 2.15 higher risk of non-vertebral fractures than men with high levels (15.2-18.8, g/dL) whereas women with anemia (hemoglobin levels <12 g/dL) had no increased fracture risk. CONCLUSION: Anemia is associated with non-vertebral fractures in men but not in women.

Diameter of the infrarenal aorta as a risk factor for abdominal aortic aneurysm: the Tromsø Study, 1994-2001.

OBJECTIVES: We aim to study whether the diameter of the non-aneurysmatic infrarenal aorta influences the risk for abdominal aortic aneurysm (AAA) and whether the larger diameter in men can explain the male predominance in AAA. DESIGN: This is a population-based follow-up study. MATERIALS AND METHODS: In 4265 men and women with a normal-sized aorta in 1994-1995, 116 incident cases of AAA were diagnosed 7 years later. The risk of an incident AAA was analysed in a multiple logistic regression model according to baseline maximal infrarenal aortic diameter, adjusted for known risk factors. RESULTS: Compared with subjects with aortic diameter in the 21-23 mm bracket, men and women with a diameter <18mm and > or =27mm had an adjusted odds ratio (OR) of 0.30 (95% confidence interval (CI): 0.10-0.88) and 4.22 (95% CI: 1.94-9.19), respectively, for an incident AAA. When adjusted for age and baseline aortic diameter, male sex was not statistically significantly associated with the incidence of AAA (OR=1.45, 95% CI: 0.93-2.30, P=0.10). CONCLUSIONS: Increased baseline diameter of the infrarenal aorta was a highly significant, strong and independent risk factor for developing an AAA. The larger aortic diameter in men than in women may be the most important explanation for the higher AAA risk in men.

The combined effect of albuminuria and inflammation on all-cause and cardiovascular mortality in nondiabetic persons.

OBJECTIVES AND DESIGN: Recent studies have shown that albuminuria accompanied by evidence of subclinical inflammation is more strongly associated with metabolic abnormalities and the development of atherosclerosis than albuminuria alone. The aim of this population-based prospective study was to examine the combined effect of albuminuria and inflammatory markers on all-cause and cardiovascular-mortality in nondiabetic individuals without macroalbuminuria. SUBJECTS AND METHODS: Urinary albumin and creatinine, some inflammatory markers (fibrinogen, white blood cell and monocyte count) and cardiovascular risk factors were measured in 5702 persons in Tromsø, Norway. Baseline data were collected in 1994-1995 and follow-up was through 2005. RESULTS: For a one standard deviation higher value of the log-transformed ratio between albumin and creatinine (ACR), the mortality rate ratio for all-cause mortality was 1.21 when adjusted for age, gender, established cardiovascular risk factors as well as fibrinogen and white blood cell count (P < 0.001). The corresponding mortality rate ratio for cardiovascular mortality was 1.24 (P < 0.001). Persons in the upper quartile of both ACR and either of the inflammatory markers had an age- and gender-adjusted all-cause and cardiovascular mortality rate that was four times that of subjects in the lowest quartiles (P < 0.001). CONCLUSION: ACR predicts all-cause and cardiovascular mortality in persons without known diabetes and macroalbuminuria. The mortality is especially high amongst individuals with elevated levels of both ACR and inflammatory markers.

Coffee drinking, mortality, and cancer incidence: results from a Norwegian prospective study.

Relationships between coffee consumption and occurrence of cancer as well as mortality were explored in a Norwegian study of 13,664 men and 2,891 women who in 1967-69 reported their coffee consumption. No statistically significant positive associations were found between coffee consumption and disease. A weak negative association was found with total cancer incidence even when the first 4 of the 11 1/2 years of follow-up were excluded, and strong negative associations with coffee drinking were noted for cancer of the kidney and nonmelanoma skin cancer. For cancer of the pancreas and bladder, no increase in incidence was found among those with a high coffee consumption. In subjects less than 65 years of age at start of follow-up, coffee drinking showed a significant inverse association with colon cancer.

Increase in weight in all birth cohorts in a general population: The Tromsø Study, 1974-1994.

BACKGROUND: Obesity is a risk factor for a number of chronic diseases. Few longitudinal studies have examined changes in body mass index (BMI [calculated as weight in kilograms divided by the square of the height in meters]). OBJECTIVE: To investigate the changes in mean BMI and the prevalence of obesity in a large cohort examined several times during a 20-year period. METHODS: Mean BMI, the percentage of subjects with low BMI (<20 kg/m(2)), and the percentage who were obese (BMI > or =30 kg/m(2)) were determined in a large population of men and women who were examined up to 4 times during a 20-year period (1974-1994/1995). In a longitudinal design, we observed 3541 men who attended all 4 screenings (1974-1994/1995) and 4993 women who attended the last 3 screenings (1979/1980-1994/1995). RESULTS: The age- (25-49 years) and sex-adjusted mean BMI increased 1 kg/m(2) in men from 1974 to 1994/1995 and 0.9 kg/m(2)in women from 1979/1980 to 1994/1995. In the last survey, subjects aged 25 to 85 years were included. In most age groups, the mean BMI exceeded 25 kg/m(2) and the prevalence of obesity was 10% or higher in men and women aged 45 years or older. In the longitudinal analysis, the mean BMI in men aged 20 to 49 years increased 2.0 kg/m(2) during 20 years of observation and increased 2.4 kg/m(2)in women aged 20 to 49 years during 15 years of observation. The increase in BMI was larger in younger men than in older men. CONCLUSIONS: Body mass index increased in every examined birth cohort (1925-1964) during the 15- to 20-year observation period. Primary prevention of further increased body weight should be a priority.

Bone mineral density in acute stroke patients: low bone mineral density may predict first stroke in women.

BACKGROUND AND PURPOSE: Osteoporosis and stroke share several risk factors, including age, smoking, low physical activity, and hypertension. Thus, low bone mineral density (BMD) and high stroke risk may be related. We examined the relationship between BMD and acute stroke in noninstitutionalized men and women aged >/=60 years. METHODS: Sixty-three stroke patients (33 women and 30 men) and 188 control subjects from the general population were included. BMD was measured by using dual-energy x-ray absorptiometry at both proximal femurs. The measurements of the stroke patients were performed 6 days after the onset of stroke. RESULTS: The BMD at the femoral neck in the female stroke patients was 8% lower than in the control subjects (P:=0.007). In men, no difference in BMD between the stroke patients and their controls was found. Women with BMD values in the lowest quartile had a higher risk of stroke than women with BMD values in the highest quartile (OR 4.8), and the probability value for linear trend over the quartiles was statistically significant (P:=0.003). The OR for stroke increased 1.9 per SD (0.13 g/cm(2)) reduction in BMD, and the association between low BMD and stroke in women remained significant when the analysis was adjusted for potential confounders. CONCLUSIONS: Female, but not male, stroke patients have lower BMD than population controls. Low BMD may predict stroke in women.

Plasma saturated and linoleic fatty acids are independently associated with blood pressure.

The role of individual fatty acids in blood pressure regulation is unclear. We studied the cross-sectional relationship of blood pressure, total plasma phospholipid fatty acid concentrations, and proportions of individual fatty acids among participants in a population study. Blood pressure was measured automatically, and plasma phospholipid fatty acids were determined by gas-liquid chromatography in 4033 healthy men 40 to 42 years old. Significant positive linear associations existed between total fatty acids and saturated fatty acids and blood pressure, whereas polyunsaturated linoleic acid was inversely associated with blood pressure. In multiple regression analyses, a 2-SD increase in total fatty acids was associated with an increase of 6.0 (95% CI, 5.1 to 6.8) mm Hg systolic blood pressure. A 2-SD increase in saturated palmitic acid was associated with 1.4 (95% CI, 0.5 to 2.3) mm Hg increase in systolic blood pressure. In contrast, a 2-SD increase in polyunsaturated linoleic acid was associated with a 1.9 (95% CI, 1.0 to 2.8) mm Hg decrease in systolic blood pressure. We conclude that plasma levels of total fatty acids, saturated fatty acids, and polyunsaturated linoleic acid are independently associated with blood pressure. The present study supports the hypothesis that the composition of dietary fat influences blood pressure.

Acyl pattern of adipose tissue triglycerides, plasma free fatty acids, and diet of a group of men participating in a primary coronary prevention program (the Oslo Study).

The acyl pattern of adipose tissue triglycerides and of plasma free fatty acids were determined after 7 yr of diet intervention on elevated plasma cholesterol in 42 men taking part in the smoking-lipid trial of the Oslo Study. Twenty-two of the men were advised to change dietary habits (mainly reduce saturated fat) whereas the remaining 20 were controls. The adipose tissue from men in the intervention group contained relatively more linoleic and linolenic acids and relatively less saturated and monounsaturated fatty acids compared to men in the control group. There were strong correlations between the relative content of several fatty acids in adipose tissue triglycerides and plasma free fatty acid. Furthermore, there was a close correlation between the intake of polyunsaturated fatty acids found in a dietary survey done 2 to 3 yr before this study and the relative content of polyunsaturated fatty acids in adipose tissue.

Changes in muscle mass, fat mass, and bone mineral content in the legs after stroke: a 1 year prospective study.

Demineralization and muscle atrophy, common among patients with hemiplegia, may be risk factors for future hip fracture. The aim of this longitudinal study was to investigate changes in lean (muscle) mass and bone mineral content (BMC) of the legs during the first year after stroke according to the patient's ambulatory level. Twenty-five patients immobilized due to acute stroke were followed. BMC and lean mass of each leg were measured at a mean of 7 days, 2 months, 7 months, and 1 year after the stroke using dual-energy X-ray absorptiometry. Both BMC and lean mass had decreased significantly in the paretic leg (p < 0.05) at the 1 year evaluation and the loss was significantly greater on the paretic side compared with the nonparetic side (p < 0.001). Patients who had not relearned to walk at the 2 month evaluation (n = 12) lost 6% (p < 0.05) of their lean mass in the paretic leg during this time period, and this mass was not regained within the subsequent 10 months. In contrast, a significant 5% loss of lean mass found at 2 months on the nonparetic side was regained completely. With respect to the patients who relearned to walk within the first 2 months (n = 13) lean mass had increased by 5% after 1 year (p < 0.05) in the nonparetic leg, whereas no significant changes were found in the paretic leg during follow-up. Both groups of patients did, however, lose bone mineral in the paretic leg during the first year after stroke (9% and 6%, respectively, p < 0.05), but only the patients who were still unable to walk by 2 months had significant bone loss in the nonparetic leg also (3%, p < 0.05). Thus, lean muscle mass is rapidly lost and may be regained shortly after stroke, whereas loss of BMC appears difficult to prevent, especially on the paretic side. Regaining muscle mass may, however, slow the loss of bone mineral.

Ambulatory level and asymmetrical weight bearing after stroke affects bone loss in the upper and lower part of the femoral neck differently: bone adaptation after decreased mechanical loading.

The aim of this 1-year prospective study of acute stroke patients was to determine the effects of walking and asymmetrical weight bearing on the loss of bone mineral in the upper and lower femoral neck. Forty patients were followed. Eight remained unable to walk, whereas 32 relearned to walk independently within 7 months (12 shortly after the stroke, 15 by 2 months, 5 by 7 months). Bone mineral density (BMD) was measured in the proximal femur within the first week after stroke and 1 year later; regional BMD changes were computed for the lower and upper femoral neck. The lower part of the femoral neck is mainly influenced by compressive stresses of the hip, the upper part by tensile stresses during walking. When comparing mean BMD loss in groups of patients according to when they relearned to walk, a statistically significant trend in BMD loss was found in the lower femoral neck on both the paretic and nonparetic sides (p < 0.01 and p = 0.01, respectively), whereas, for the upper femoral neck, no significant trend was seen (p >/= 0.1). In addition, the body weight distribution during standing was assessed by use of a force-plate in 38 patients who could stand independently at the 7 month evaluation. The only significant correlation between changes in BMD and asymmetrical weight bearing was found in the lower femoral neck on the paretic side (r = 0.6, p < 0.001). In conclusion, this study shows that the reduction in BMD in the femoral neck occurs mainly in the lower part of the neck and on the paretic side. The BMD loss depended on when or if the patients relearned to walk, but also on the amount of body weight born on the paretic leg. Thus, measuring the lower part of the femoral neck gives a better estimate of the impact of gait and weight bearing than measuring the total femoral neck.

Communicating with and treating cancer patients: how does the use of non-proven therapies and patients' feeling of mental distress influence the interaction between the patient and the hospital staff.

A questionnaire-based study was carried out at the Department of Oncology, University Hospital of Tromsø, during the period July 1990-October 1991. The 252 participating patients received a questionnaire at arrival at the oncology unit and the surviving patients a follow-up questionnaire at home 4 months later. The aim of the study was to assess whether patients' attitudes to information about their malignant disease and satisfaction with the given treatment correlated to their use of non-proven therapies (NPTs) and reported mental distress. Patients under 45 years of age significantly more often preferred comprehensive medical information than older patients (83% versus 52%, P = 0.001). Better educated patients were more satisfied with the information given by their general practitioner (GP) (P = 0.05) and at their local hospital (P = 0.02) than other patients. Of all responders, 81% of the patients treated in the department were completely satisfied with the opportunities to ask questions while 87% reported being given comprehensive information. Only 2% of the patients reported to have received unwanted information. Better educated patients expressed less satisfaction with the information given and the possibility of influencing their own treatment at the Department of Oncology (P = 0.02). Patients expressing mental distress wanted less information (P = 0.05) and expressed less satisfaction with the quality of the perceived information in the oncology unit (P = 0.004). They were also less satisfied with the treatment given (P = 0.05) and their own influence on the treatment decision (P = 0.02). Users of NPT did not feel the received treatment to be the best possible (P = 0.04).

Do reproductive factors influence colorectal cancer survival?

During 29 years follow up of 63,090 Norwegian women, 1347 women had a diagnosed cancer of the colon or rectum. Seven hundred and fifty-five of these women (56%) subsequently died of colorectal cancer. We investigated possible relationships between reproductive history and cancer survival and found little evidence that reproductive history is of prognostic value for colorectal cancer survival.

Population-based study of age at menopause and ultrasound assessed carotid atherosclerosis: The Tromsø Study.

Early menopause has been associated with higher prevalence and incidence of cardiovascular disease and death than late menopause, indicating that early loss of ovarian function and subsequent deficiency of estrogen may promote such diseases. No population-based studies have, however, examined the relation between age at menopause and atherosclerosis. We assessed the prevalence and the extent of carotid atherosclerosis by high-resolution B-mode ultrasound in 2588 postmenopausal women who participated in a population health survey. Information about age at menopause and menarche, parity, use of hormone replacement therapy, and prevalent diseases was collected, and cardiovascular risk factor levels were measured. Women with late menopause and women who ever had used postmenopausal estrogens had significantly less atherosclerosis than women with early menopause and those with never use of estrogen. This study provides further support for the hypothesis that estrogen protects women against cardiovascular disease.
