Quality of life in treated patients with acromegaly.

CONTEXT: It is not known to what extent quality of life of patients treated for acromegaly is dependent on levels of GH and IGF-I attained. OBJECTIVE: The objective of this study is to examine the health-related quality of life (HRQoL) and its dependence on treatment outcome and modality in a nationwide survey of acromegalic patients. DESIGN, SETTING, AND PATIENTS: All eligible patients with acromegaly, diagnosed from January 1980 through December 1999 in Finland, were invited to a follow-up study, carried out 11.4 +/- 5.7 (mean +/- sd) yr after initial treatment. HRQoL of the patients, measured by the generic 15D instrument, was compared with that of the general population. Factors related to HRQoL were analyzed by logistic regression. MAIN OUTCOME MEASURE: HRQoL was the main outcome measure. RESULTS: Of 277 eligible patients, 231 (83.4%) participated in the follow-up study. Of them, 51.1% were in remission according to consensus criteria. The patients reported reduced HRQoL in comparison to the age- and gender-standardized general population (P < 0.001). HRQoL was related to nadir GH in oral glucose tolerance test (GHOGTT) in an inverted U-shaped fashion (overall P = 0.021). Patients with GHOGTT nadir values between 0.3-1.0 microg/liter had a better HRQoL than those with lower or higher values. A normal IGF-I (P = 0.038) and not having had radiotherapy (P = 0.004) were also associated with a better HRQoL. CONCLUSIONS: HRQoL is reduced in treated patients with acromegaly. The best HRQoL may be achieved by normalization of IGF-I and by targeting the GHOGTT nadir to levels between 0.3 and 1.0 microg/liter. Radiotherapy is associated with adverse HRQoL.

Serum lipids and low back pain: an association? A follow-up study of a working population sample.

STUDY DESIGN: Cohort study with 5-, 10-, and 28-year follow-up. OBJECTIVES: To examine associations between baseline serum lipid concentrations and later low back pain (LBP). SUMMARY OF BACKGROUND DATA: Atherosclerosis of the lumbar vessels has been suggested as a mechanism leading to disc degeneration and LBP. Cholesterol is considered essential for atherosclerosis development. METHODS: A sample (n = 902) of employees in an engineering company was examined for serum total cholesterol and triglycerides, body mass index (BMI), smoking, exercise, work history, and LBP in 1973. By November 2000, 232 subjects had died. In 1978, 748 (84% of the survivors), in 1983, 654 (76%), and in 2000, 546 (81%) responded to a follow-up questionnaire. RESULTS: In men, baseline serum total cholesterol predicted new cases of radiating LBP in the 5-year follow-up (highest tertile vs. lowest: odds ratio [OR], 2.5; 95% confidence interval [CI], 1.1-5.9) and in the 10-year follow-up (OR, 2.8; 95% CI, 1.3-6.1), adjusted for age, occupational class, work history, BMI, smoking and exercise. Also, serum triglycerides predicted new cases in the latter examination (OR, 2.6; 95% CI, 1.2-5.8). In women, no associations were seen until the 10-year follow-up, when their results were similar to those in men. In the total material, serum total cholesterol predicted radiating LBP reported both at the 10- and the 28-year follow-up. CONCLUSIONS: High serum lipids predicted incident radiating LBP, consistent with the atherosclerosis-LBP hypothesis.

Intake of fish and long-chain n-3 fatty acids and the risk of coronary heart mortality in men and women.

This prospective study investigated the relationship between the consumption of fish and intake of long-chain n-3 fatty acids and the risk of coronary heart mortality in 2775 men and 2445 women aged from 30 to 79 years who were free of CHD and had participated in a health examination survey from 1967 to 1972. In total, 335 men and 163 women died of CHD during a follow-up until the end of 1992. A dietary history interview method provided data on habitual consumption of fish and other foods over the preceding year at baseline. The intakes of long-chain n-3 fatty acids were calculated on the basis of food composition values of Finnish foods. Higher consumption of fish was associated with a decreased risk of CHD among women, whereas no significant association was seen among men. The relative risk between the highest and the lowest quintile for fish consumption was 1.00 (95 % CI 0.70, 1.43; P for trend 0.83) for men and 0.59 (95 % CI 0.36, 0.99; P for trend 0.02) for women in analysis adjusting for age, energy intake, geographical area, BMI, serum cholesterol, blood pressure, smoking, occupation and diabetes; however, after adjustment for dietary confounders this association was no longer significant. The intake of n-3 fatty acids was not significantly associated with the risk of CHD in either men or women. In conclusion, our results for women are in line with the suggested protective effect of fish consumption against CHD but a similar association was not, however, found in men.

Socioeconomic inequities in invasive cardiac procedures among patients with incident angina pectoris or myocardial infarction.

AIMS: In many countries, systematic socioeconomic disparities have emerged in the use of invasive cardiac procedures among myocardial infarction patients and hospitalized coronary patients. This study prospectively examined socioeconomic differences in the use of cardiac procedures in a national cohort of incident coronary patients. METHODS: The data were based on individual register linkages among 49,846 patients with incident angina pectoris (AP) or myocardial infarction (MI) during one-year follow-up in 1995-98 in Finland. Socioeconomic differences in invasive coronary procedures were examined using proportional hazard models. RESULTS: The analyses showed that women, AP patients, and persons with lower socioeconomic status received fewer procedures during the one-year follow-up than men, MI patients, and those with higher socioeconomic status. Socioeconomic differences in the utilization of cardiac procedures were similar in both AP and MI groups, among both men and women, and by all socioeconomic indicators: social class, education, and income. Disparities were already emerging after the 28-day follow-up among men and women in both patient groups, and they persisted throughout the study period. Controlling for disease severity, comorbidity, and hospital district did not modify the results. CONCLUSIONS: Socioeconomic disparities in receiving invasive coronary procedures among AP patients without MI were similar to those in MI patients.

Low metacarpal index predicts hip fracture: a prospective population study of 3,561 subjects with 15 years of follow-up.

BACKGROUND: Metacarpal index (MCI), measured from hand radiographs as the ratio between combined cortical thickness and bone diameter, has been suggested for assessment of bone mass and risk of osteoporotic fracture. We studied MCI for its ability to predict hip fractures. METHODS: Hand radiographs were taken and MCI determined in 3,561 subjects from a representative population sample of 8,000 Finns who were 30 years of age or over in 1978-80. Record linkage to the National Hospital Discharge Register identified 117 subjects who had been hospitalized for primary treatment of hip fracture by the end of 1994. RESULTS: High age, low body mass index, tall stature and smoking at baseline showed, independently of each other, significant associations with low MCI. Low MCI was a strong predictor of hip fracture. When adjusted for all potential confounding factors, the relative risk of hip fracture per decrement of MCI by one standard deviation (0.1) was 1.5 (95% CI 1.2-1.8). INTERPRETATION: Low MCI is associated with known risk factors of osteoporosis and predicts hip fracture. Since hand radiographs are easily available at low cost, measurements of MCI can be used as an alternative approach to find osteoporotic individuals with a high risk of hip fracture.

Prevalence and determinants of isolated clinic hypertension in the Finnish population: the Finn-HOME study.

BACKGROUND: Previous studies performed in selected hypertensive subjects have reported several possible determinants of isolated clinic hypertension (ICH). The purpose of this study was to assess the prevalence and determinants of ICH in a randomly selected nationwide population. METHODS: We studied a representative sample of the general adult population (1440 45-74-year-old subjects) in Finland not treated for hypertension. The subjects were drawn from the participants of a multidisciplinary epidemiological survey, the Health 2000 Study. Subjects included in the study underwent a clinical interview, determination of serum lipids and glucose, measurement of clinic and home blood pressure (BP), and psychometric tests for psychological distress, hypochondriasis, depression, and alexithymia. The diagnosis of ICH was based on a clinic BP of 140/90 mmHg or greater and a home BP less than 135/85 mmHg. RESULTS: The prevalence of ICH in the untreated Finnish adult population was 15.6 and 37.5% among untreated clinic hypertensive individuals. In a multivariate logistic regression analysis, ICH was associated with mildly elevated systolic and diastolic BP, lower body mass index (BMI), and non-smoking status. Subjects with ICH represent an intermediate group between the normotensive and sustained hypertensive individuals where cardiovascular risk is concerned (age, BP, diabetes prevalence, lipid profile, and BMI). CONCLUSION: ICH is a common phenomenon in the general population. Non-smoking individuals with mildly elevated BP and low BMI have a higher risk of ICH. Physicians should disassociate the diagnosis of ICH from any psychosocial disorders, but should remember that patients with ICH have an increased risk of cardiovascular disease.

Comparison of agreement between clinic and home-measured blood pressure in the Finnish population: the Finn-HOME Study.

BACKGROUND: The purpose of this study was to assess the agreement, mean difference, and the detection and control rates of hypertension, between home and clinic blood pressure (BP) measurement in the Finnish population. Variation in home BP during the measurements was also examined. METHODS: We studied a representative sample of the adult population (2051 45-74-year-old individuals) in Finland. Subjects included in the study underwent a clinical interview and measurement of clinic and home BP. Thresholds for elevated clinic and home BP were 140/90 and 135/85 mmHg. RESULTS: The mean difference between home and clinic BP, which increased with BP, was 7.7/3.4 mmHg. Overall agreement in diagnosis was only 75.2% (kappa coefficient 0.50). As compared with home BP, clinic BP overestimated the prevalence of hypertension (48.8 versus 42.5%, P < 0.001) and non-significantly underestimated the control of hypertension (28.7 versus 32.8%, P = 0.11). Evening home BP was 4.1/0.4 mmHg higher than morning BP among untreated subjects, but this difference was non-existent or reversed (0.5/-1.4 mmHg) among treated hypertensive individuals. Home BP decreased with an increasing number of measurements. CONCLUSIONS: The agreement between home and clinic BP in diagnosing hypertension according to the current guidelines is moderate at best, and the difference between home and clinic BP becomes larger at higher levels of BP. Because of the noticeable differences between these two methods, and the better prognostic accuracy of home BP, we endorse the use of home measurements in clinical practice.

Are there socioeconomic differences in myocardial infarction event rates and fatality among patients with angina pectoris?

BACKGROUND: Systematic socioeconomic differences in mortality have been reported among myocardial infarction (MI) patients in many countries, including Finland. The findings have been similar irrespective of country, study period, age group, or length of follow up, but few studies have examined the disparities among other groups of coronary patients. This study examined whether similar socioeconomic differences in outcomes exist among patients with angina pectoris (AP). METHODS: The data were based on individual register linkages among a population based 40-79 year-old cohort of 61,350 patients with incident AP or MI during 1995-1998 in Finland. Two year coronary heart disease mortality and one year MI incidence and its 28 day case fatality was studied among AP patients using Cox's and logistic regression analysis, and the results compared with those of the MI patient group. RESULTS: A clear socioeconomic pattern was found in two year coronary heart disease (CHD) mortality: the lower the socioeconomic group the higher the mortality risk. The socioeconomic patterning of mortality was similar to that found among MI patients. Controlling for comorbidity or disease severity did not change the results. Among AP patients a similar pattern was also found in MI incidence during the follow up, but no systematic socioeconomic differences were detected in its 28 day case fatality. CONCLUSIONS: Socioeconomic differences in CHD outcomes also exist among angina patients. These results suggest that targeted measures of secondary prevention are needed among CHD patients with lower socioeconomic status to reduce socioeconomic disparities in fatal and non-fatal coronary events.

Differential transmission of type 1 diabetes from diabetic fathers and mothers to their offspring.

We studied the incidence of type 1 diabetes in the offspring of patients with childhood- and adolescent-onset type 1 diabetes and several risk factors predicting the risk. We defined the diabetes status in the offspring of all probands who were included in the nationwide register of Finnish type 1 diabetic patients diagnosed at the age of < or =17 years from 1965 to 1979. A total of 5,291 offspring at risk contributed 72,220 person-years of follow-up between 1970 and 2003. Of them, 259 offspring developed type 1 diabetes by the end of 2003, giving a cumulative incidence of 6.7% (95% CI 5.9-7.5) by the age of 20 years. The incidence of type 1 diabetes in the offspring between the years 1980 and 2003 was 35.3, 44.6, and 44.6 per 10,000 person-years for the age-groups 0-4, 5-9, and 10-14 years, respectively. Poisson regression analyses showed a marked increase in incidence of 5.3% per year from 1983 to 2003. The greatest increase occurred in the youngest offspring, aged 0-4 years. Of the offspring of male probands, 7.8% were affected by the age of 20 years compared with 5.3% of the offspring of female probands (relative risk 1.7 [95% CI 1.3-2.2]). The young age at onset of diabetes increased the risk of type 1 diabetes in the offspring of diabetic fathers but not in the offspring of diabetic mothers. In conclusion, our findings revealed that in the offspring of type 1 diabetic patients, the increase in the recurrence risk of type 1 diabetes was not more rapid compared with that in the background population. In the multivariate analyses, statistically significant predictors of type 1 diabetes in the offspring were male sex of the diabetic parent, young age at diagnosis in the male parent, and the more recent year of birth of the offspring.

Cardiovascular risk factors and low-back pain in a long-term follow-up of industrial employees.

OBJECTIVES: Atherosclerosis of the lumbar vessels has been suggested as a mechanism leading to low-back pain (LBP). We studied whether seven cardiovascular disease (CVD) risk factors predict LBP. METHODS: A sample (N=902) stratified by gender, age, and occupational class was drawn from employees in an engineering company in 1973 and examined for body mass index (BMI), smoking, exercise, serum total cholesterol and triglyceride concentrations, systolic blood pressure (SBP), diastolic blood pressure (DBP), and LBP. By November 2000, 232 persons had died, 108 from cardiovascular causes. In 2000, 546 (81% of the survivors) responded to a follow-up questionnaire on, for example, LBP. RESULTS: Among the men, frequent local LBP at follow-up was predicted by high triglyceride and DBP levels and being a past smoker at baseline, adjusted for age, occupational class and frequent local LBP at baseline. In analogous models, high triglyceride and SBP levels and smoking (past and current) predicted frequent radiating LBP. An increased LBP score was predicted by a high BMI, serum total cholesterol, triglyceride, SBP and DBP levels, and smoking status at baseline. When BMI was allowed for, the associations between triglyceride level and all LBP outcomes persisted, as well as the association between SBP and frequent radiating LBP and an increased LBP score. An overall score of CVD risk factors showed a graded association with increased LBP. Among the women, a high BMI predicted frequent local and radiating LBP, and smoking at baseline predicted frequent radiating LBP and an increased LBP score. CONCLUSIONS: The study adds to the evidence supporting the atherosclerosis-LBP hypothesis particularly for men.

Coronary heart disease: from a disease of middle-aged men in the late 1970s to a disease of elderly women in the 2000s.

AIMS: To analyse secular changes in the prevalence of coronary heart disease (CHD) and to assess changes in the burden of CHD at population level. METHODS AND RESULTS: Data were used from two large cross-sectional health examination surveys representing the entire Finnish adult population in 1980 and 2000. In the 1978-80 survey, the sample covered 5101 individuals aged > or =45, of whom 88% participated. The 2000-2001 survey comprised 5310 individuals in the same age range. Participation rate in the health examination was 87%. Prevalence of CHD decreased in men and women under the age of 65 and increased among those aged > or =75. Prevalence of large Q-waves indicating previous myocardial infarction decreased in all male age groups and in women aged 65-74. The total estimated number of persons with CHD increased by 18% (95% CI=6-30) during the past 20 years in Finland. In 1980, the most dominant CHD group was men aged 45-64, whereas in 2000, women aged > or =75 comprised the largest CHD group. CONCLUSION: Although the prevalence of CHD has decreased among middle-aged persons, the number of CHD cases has increased during the past 20 years in Finland.

Incidence of end-stage renal disease in patients with type 1 diabetes.

CONTEXT: End-stage renal disease (ESRD) is one of the most severe complications of type 1 diabetes. Yet, data on patients' risk of developing ESRD are sparse. OBJECTIVES: To estimate the long-term risk of developing ESRD and to assess how age at diagnosis of diabetes, time period of diagnosis, and sex affect the risk. DESIGN, SETTING, AND PATIENTS: A cohort of all patients younger than 30 years diagnosed as having type 1 diabetes in Finland in 1965-1999 (n = 20,005) was identified from the Finnish Diabetes Register. The cohort was followed up from diagnosis of diabetes until development of ESRD (dialysis or kidney transplantation as identified from the Finnish Registry for Kidney Diseases), death, or end of follow-up on December 31, 2001. MAIN OUTCOME MEASURE: Cumulative incidence of ESRD, accounting for death as a competing risk. RESULTS: The cohort was followed up for maximally 37 years, with a median of 16.7 years. During 346 851 person-years, 632 patients developed ESRD. The cumulative incidence of ESRD was 2.2% at 20 years and 7.8% at 30 years after diagnosis. The risk of developing ESRD was lowest in patients whose diagnosis occurred at younger than 5 years. The risk of ESRD was lower for patients diagnosed as having type 1 diabetes in later years. The risk did not differ significantly between sexes. CONCLUSIONS: With regard to ESRD, the prognosis of type 1 diabetes has improved during the past 4 decades. Children diagnosed as having diabetes before age 5 years have the most favorable prognosis. Overall, incidence of ESRD appears to be lower than previously estimated.

A nationwide survey of mortality in acromegaly.

CONTEXT: Increased mortality in acromegaly has been confined to those with posttreatment basal GH of 2.5 microg/liter or greater, but the impact of IGF-I and pituitary radiotherapy on mortality has remained controversial. OBJECTIVE: The purpose of this nationwide survey was to examine the all-cause mortality of patients with acromegaly and evaluate the impact of treatment outcome and mode of treatment on survival. DESIGN, SETTING, AND PATIENTS: All-cause mortality of all patients with acromegaly diagnosed during January 1980 and December 1999 in the five university hospitals of Finland was followed up by the end of 2002 (12.5 +/- 5.6 yr) and compared with that of the general population by using age- and gender-adjusted standardized mortality ratios (SMRs). Logistic regression analysis was used to investigate factors related to mortality within the survey population. MAIN OUTCOME MEASURE: Mortality was the main outcome measure. RESULTS: Of the 334 patients, 56 (16.8%) had died during follow-up. SMR of the patients was 1.16 [confidence interval (CI) 0.85-1.54, not significant (NS)]. However, patients with basal serum GH concentration 2.5 microg/liter or greater (SMR 1.63, CI 1.10-2.35, P < 0.001) measured 5.2 +/- 4.4 yr after the initial treatment, and those irradiated (SMR 1.69, CI 1.05-2.58, P < 0.001) showed excess mortality. In a multivariate model, the effect of radiotherapy was of borderline significance only (P = 0.083). Posttreatment IGF-I levels, available for 72.2% of the patients, did not have impact on mortality. CONCLUSIONS: The posttreatment basal GH concentration less than 2.5 microg/liter in acromegalic patients is associated with a normal lifespan. Excess mortality is confined to poorly controlled patients and possibly those who have received conventional radiotherapy.

Dietary patterns and the incidence of type 2 diabetes.

Major dietary patterns were studied for the ability to predict type 2 diabetes mellitus in a cohort of 4,304 Finnish men and women aged 40-69 years and free of diabetes at baseline in 1967-1972. Factor analysis was used to identify dietary patterns from dietary data that were collected using a 1-year dietary history interview. A total of 383 incident cases of type 2 diabetes occurred during a 23-year follow-up. Two major dietary patterns were identified. The pattern labeled "prudent" was characterized by higher consumption of fruits and vegetables, and the pattern labeled "conservative" was characterized by consumption of butter, potatoes, and whole milk. The relative risks (adjusted for nondietary confounders) between the extreme quartiles of the pattern scores were 0.72 (95% confidence interval: 0.53, 0.97; p(trend) = 0.03) for the prudent pattern and 1.49 (95% confidence interval: 1.11, 2.00; p(trend) = 0.01) for the conservative pattern. Thus, the prudent dietary pattern score was associated with a reduced risk and the conservative pattern score was associated with an increased risk of type 2 diabetes. In light of these results, it appears conceivable that the risk of developing type 2 diabetes can be reduced by changing dietary patterns.

A nationwide population-based survey on visual acuity, near vision, and self-reported visual function in the adult population in Finland.

PURPOSE: To estimate the prevalence rates of habitual visual acuity (VA) levels and visual impairment in Finland and to assess their correlation with self-reported visual function. DESIGN: Cross-sectional population-based study. PARTICIPANTS: Subjects were selected randomly from the Finnish population aged 30 years or older. Of 7979 eligible people, 7393 (93%) were interviewed, 6771 (85%) were examined, and 6663 (84%) had distance VA assessed. METHODS: Participants underwent a home interview and a comprehensive examination including measuring binocular VA for distance and for near with the participants' current spectacles, if any. MAIN OUTCOME MEASURES: The level of VA for distance and for near with current spectacle correction. The self-reported capability to read newsprint and television text and the ability to move about without being restricted by reduced vision. RESULTS: The prevalence of good to moderate VA for distance (VA> or =0.5 [> or =20/40]) measured with current spectacles was 95.9%, and 87.4% had a VA level of 0.8 (20/25) or better. The prevalence of habitual visual impairment (VA< or =0.25 [< or =20/80]) was 1.6%, and 0.5% were blind (VA<0.1 [<20/200]). The prevalence of visual impairment increased significantly with age (P<0.001), especially in the age group of 65 to 74 years and upward. There was no gender difference in VA for distance, but decreased near vision (VA< or =0.25 [< or =20/80]) was significantly more common in men than in women (P<0.01). By applying the imputated numbers of visually impaired and blind participants to the Finnish population (approximately 3 million aged 30 years or older), there were approximately 65000 (2.1%) visually impaired and 17000 (0.6%) blind adult persons in the country in 2000. The correlation between self-reported visual ability and measured visual function was moderate but statistically significant (r = 0.27-0.40; P<0.0001). The proportion of people with reading difficulties or who were unable to read newsprint has decreased 7% during the last 2 decades. CONCLUSIONS: Functional visual impairment increased with age especially in the age group of 65 to 74 years and upward and was as prevalent in women as in men. The prevalence of people with reading difficulties has decreased considerably since 1980.

A six-fold gradient in the incidence of type 1 diabetes at the eastern border of Finland.

OBJECTIVE: Type 1 diabetes results from gene-environment interactions in subjects with genetic susceptibility to the disease. We assessed the contribution of environmental and genetic factors to type 1 diabetes by comparing the incidence in two neighboring populations living in conspicuously different socioeconomic circumstances. RESEARCH DESIGN AND METHODS: We compared the incidence over a 10-year period (1990-99) in children younger than 15 years of age living in the Karelian Republic of Russia and in Finland. The frequency of susceptible and protective human leukocyte antigen (HLA)-DQ alleles was analyzed in 400 non-diabetic schoolchildren from Russian Karelia and 1000 Finnish subjects. RESULTS: The average annual age-adjusted incidence of type 1 diabetes was lower in Russian Karelia than in Finland: 7.4 per 100000 (95% confidence interval 3.5-11.3) versus 41.4 per 100000 (37.3-45.5), while there were no differences in the frequency of the HLA DQ genotypes predisposing to type 1 diabetes in the background populations. The incidence rate did not differ significantly between different ethnic groups in Russian Karelia (Finns/Karelians, Russians, others). CONCLUSIONS: There is a close to six-fold gradient in the incidence of type 1 diabetes between Russian Karelia and Finland, although the predisposing HLA DQ genotypes are equally frequent in the two populations. This suggests that environmental factors contribute to this steep difference in the incidence rate between these adjacent regions.

Gender differences in the treatment and secondary prevention of CHD at population level.

OBJECTIVES: Treatment and secondary prevention measures, received by persons with coronary heart disease (CHD), are insufficiently known at the moment. The aim of this study was to investigate the state of treatment and secondary prevention of CHD in a population-based sample and to analyze possible gender differences in different age groups. DESIGN: 300 men and 300 women with CHD were identified from a nationally representative health examination survey with 88% participation rate, carried out in Finland in 2000-2001. RESULTS: Revascularization had been performed on 34% (95% confidence interval 29, 40%) of men and 13% (8, 18%) of women. Moreover, 76% (71, 81%) of the men and 63% (57, 69%) of the women used antithrombotic medications. Two thirds of both men and women used beta-blockers and one third lipid-lowering medication. Smoking was more common among men, whereas obesity and high total cholesterol concentration were more common among women. CONCLUSIONS: Secondary prevention of CHD is far from optimal and there are gender differences in the care of CHD.
