Abstract
INTRODUCTION APOE ɛ4 allele predisposes to high cholesterol and increases the risk for lifestyle-related diseases such as Alzheimer's disease (AD) and cardiovascular diseases (CVD). The aim of this study was to analyse interrelationships of APOE genotypes with lipid metabolism and lifestyle factors in middle-aged Finns among whom the CVD risk factors are common. METHODS Participants (n=211) were analysed for APOE ε genotypes, physiological parameters and health- and diet-related plasma markers. Lifestyle choices were determined by a questionnaire. RESULTS APOE genotypes ε3/ε4 and ε4/ε4 (ε4 group) represented 34.1% of the participants. Genotype ε3/ε3 (ε3 group) frequency was 54.5%. Carriers of ε2 (ε2 group; ε2/ε2, ε2/ε3 and ε2/ε4) represented 11.4%; 1.9 % were of the genotype ε2/ε4. The LDL and total cholesterol levels were lower (P<0.05) in the ε2 carriers than in the ε3 or ε4 groups, while the ε3 and ε4 groups did not differ. Proportions of plasma saturated fatty acids were higher (P<0.01) and omega-6 fatty acids lower (P=0.01) in the ε2 carriers compared with the ε4 group. The ε2 carriers had a higher (P<0.05) percentage of 22:4n-6 and 22:5n-6 and a lower (P<0.05) percentage of 24:5n-3 and 24:6n-3 than individuals without the ε2 allele. CONCLUSIONS The plasma fatty acid profiles in the ε2 group were characterised by higher SFA and lower omega-6 fatty acid proportions. Their lower cholesterol values indicated a lower risk for CVD compared with the ε4 group. A novel finding was that the ε2 carriers had different proportions of 22:4n-6, 22:5n-6, 24:5n-3 and 24:6n-3 than individuals without the ε2 allele. The significance of the differences in fatty acid composition remains to be studied.

Long-term outcomes of lifestyle intervention to prevent type 2 diabetes in people at high risk in primary health care. Prim Care Diabetes 2021; 15:444-450. [PMID: 33771515 DOI: 10.1016/j.pcd.2021.03.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 02/23/2021] [Accepted: 03/12/2021] [Indexed: 12/30/2022]
Abstract
AIMS The Finnish National Diabetes Prevention Program (FIN-D2D) was the first large-scale diabetes prevention program in a primary health care setting in the world. The risk reduction of type 2 diabetes was 69% after one-year intervention in high-risk individuals who were able to lose 5% of their weight. We investigated long-term effects of one-year weight change on the incidence of type 2 diabetes, cardiovascular events, and all-cause mortality. METHODS A total of 10,149 high-risk individuals for type 2 diabetes were identified in primary health care centers and they were offered lifestyle intervention to prevent diabetes. Of these individuals who participated in the baseline screening, 8353 had an oral glucose tolerance test (OGTT). Complete follow-up data during one-year intervention were available for 2730 individuals and those were included in the follow-up analysis. The long-term outcome events were collected from national health registers after the median follow-up of 7.4 years. RESULTS Among individuals who lost weight 2.5-4.9% and 5% or more during the first year, the hazard ratio for the incidence of drug-treated diabetes was 0.63 (95% CI 0.49-0.81, p = 0.0001), and 0.71 (95% CI 0.56-0.90, p = 0.004), respectively, compared with those with stable weight. There were no significant differences in cardiovascular events or all-cause mortality among study participants according to one-year weight changes. CONCLUSIONS High-risk individuals for type 2 diabetes who achieved a moderate weight loss by one-year lifestyle counseling in primary health care had a long-term reduction in the incidence of drug-treated type 2 diabetes. The observed moderate weight loss was not associated with a reduction in cardiovascular events.

Abstract
BACKGROUND The APOE ε4 allele is associated with higher risks of cardiovascular diseases and Alzheimer disease than ε3 and ε2. OBJECTIVES We studied the effectiveness of dietary and lifestyle guidance and personal genetic risk information [ε4 carrier (ε4+); ε4 noncarrier (ε4-)] as motivators for a healthier lifestyle. METHODS A total of 188 healthy Finnish volunteers (82.4% women; mean ± SD age: 51.0 ± 5.6 y; BMI: 26.0 ± 3.6 kg/m2; total cholesterol: 5.2 ± 0.9 mmol/L) participated in our randomized intervention study. The participants were genotyped for APOE and divided into intervention (INT; INTε4+, n = 33; INTε4-, n = 57) and control groups (CTRL; CTRLε4+, n = 36; CTRLε4-, n = 62). Blood samples, measured observations, and questionnaire data were obtained at baseline and at 1 and 1.5 y. INT participants received their ε4 carrier status at baseline. Monthly Internet-based guidance based on the Finnish Dietary guidelines was provided for all. RESULTS The proportion of SFAs in plasma over time fluctuated less in INTε4+ than in the other groups (P-interaction < 0.05; primary outcome). The lifestyle guidance increased vegetable consumption from 3.5 to 3.6 portions/d, improved the dietary fat quality score by 5.3%, increased the plasma n-3 (ω-3) FA proportion by 7.3%, and decreased the consumption of high-fat/high-sugar foods from 7.3 to 6.5 portions/wk and total- and LDL-cholesterol concentrations by 4.3% and 6.1%, respectively, in the entire participant population (P < 0.05; secondary outcome). Compared with the ε4- participants, ε4+ participants had 2.4% higher plasma n-6 (ω-6) FA, lower C-peptide (3.9 compared with 4.2 nmol/L × h) and sensitive C-reactive protein values, and decreased plasma malondialdehyde concentrations over time (P < 0.05; secondary outcome). CONCLUSIONS Lifestyle guidance given to healthy Finnish participants yielded small but beneficial changes. The INTε4+ group did not seem markedly more responsive to the guidance than the other groups.This trial was registered at clinicaltrials.gov as NCT03794141.

A Long-Term Follow-Up Study on Disclosing Genetic Risk Information (APOE) to Promote Healthy Lifestyles in Finland. Lifestyle Genom 2019; 11:147-154. [PMID: 31234179 DOI: 10.1159/000500199] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Accepted: 04/02/2019] [Indexed: 12/20/2022] Open
Abstract
AIM This observational follow-up study was designed to assess the long-term behavioural and clinical effects of receiving personal genetic risk information. The information disclosed was the carrier status of the apolipoprotein E (APOE)alleles, which differentially contribute to the genetic risk for cardiovascular disease (CVD) and Alzheimer's disease. METHODS This study forms a continuum with a previous 1-year intervention (2010-2011) monitoring the effects of disclosing the carrier status of the APOE ε4risk allele. The follow-up measurements, performed 5.5 years post-intervention, included clinical measurements (blood values and anthropomorphic parameters) and questionnaires (psychological and behavioural factors). The participants were healthy adult volunteers, aged 26-73 years (n = 70) who had participated in the previous intervention, and received their APOE allele status either at the beginning (former test group) or the end of the intervention (former control group). RESULTS Personal genetic risk information resulted in a moderate health-conscious change in diet and had a slight positive long-term effect on clinical factors, particularly the serum lipids. These improvements were subsequent to the disclosure of genetic information and occurred mainly in the APOE ε4-positive members of the former control group, that is, those who were at increased genetic risk for CVD but had not been informed of their status before the end of the intervention. In contrast, changes in the values and health behaviour of the APOE ε4-positive individuals in the former test group, who had already changed their health behaviour during the previous intervention as a result of being informed of their carrier status, varied more: some continued to improve, some remained at their previously improved level, and some relapsed slightly. Both groups had nonetheless displayed an improvement immediately subsequent to the disclosure of their personal genetic risk. CONCLUSION Receiving information on increased personal genetic risk (carrier status of APOE ε4)for CVD provided the motivation for improvements in health behaviour. The resulting changes, while modest, in most cases remained visible even after a number of years.

Abstract
BACKGROUND Loss-of-function mutations in the SGLT1 (sodium/glucose co-transporter-1) gene result in a rare glucose/galactose malabsorption disorder and neonatal death if untreated. In the general population, variants related to intestinal glucose absorption remain uncharacterized. OBJECTIVES The goal of this study was to identify functional SGLT1 gene variants and characterize their clinical consequences. METHODS Whole exome sequencing was performed in the ARIC (Atherosclerosis Risk in Communities) study participants enrolled from 4 U.S. communities. The association of functional, nonsynonymous substitutions in SGLT1 with 2-h oral glucose tolerance test results was determined. Variants related to impaired glucose tolerance were studied, and Mendelian randomization analysis of cardiometabolic outcomes was performed. RESULTS Among 5,687 European-American subjects (mean age 54 ± 6 years; 47% male), those who carried a haplotype of 3 missense mutations (frequency of 6.7%)-Asn51Ser, Ala411Thr, and His615Gln-had lower 2-h glucose and odds of impaired glucose tolerance than noncarriers (β-coefficient: -8.0; 95% confidence interval [CI]: -12.7 to -3.3; OR: 0.71; 95% CI: 0.59 to 0.86, respectively). The association of the haplotype with oral glucose tolerance test results was consistent in a replication sample of 2,791 African-American subjects (β = -16.3; 95% CI: -36.6 to 4.1; OR: 0.39; 95% CI: 0.17 to 0.91) and an external European-Finnish population sample of 6,784 subjects (β = -3.2; 95% CI: -6.4 to -0.02; OR: 0.81; 95% CI: 0.68 to 0.98). Using a Mendelian randomization approach in the index cohort, the estimated 25-year effect of a reduction of 20 mg/dl in 2-h glucose via SGLT1 inhibition would be reduced prevalent obesity (OR: 0.43; 95% CI: 0.23 to 0.63), incident diabetes (hazard ratio [HR]: 0.58; 95% CI: 0.35 to 0.81), heart failure (HR: 0.53; 95% CI: 0.24 to 0.83), and death (HR: 0.66; 95% CI: 0.42 to 0.90). CONCLUSIONS Functionally damaging missense variants in SGLT1 protect from diet-induced hyperglycemia in multiple populations. Reduced intestinal glucose uptake may protect from long-term cardiometabolic outcomes, providing support for therapies that target SGLT1 function to prevent and treat metabolic conditions.

The effect of age and gender on the genetic regulation of serum 25-hydroxyvitamin D - the FIN-D2D population-based study. J Steroid Biochem Mol Biol 2018; 178:229-233.

Abstract
In addition to sunlight and dietary sources, several genes in the metabolic pathway of vitamin D affect serum 25-hydroxyvitamin D (25OHD) concentration. It is not known whether this genetic regulation is influenced by host characteristics. We investigated the effect of age and gender on the genetic regulation of serum 25OHD concentration. In total, 2868 Finnish men and women aged 45-74 years participated in FIN-D2D population-based health survey in 2007. Of the 2822 participants that had serum 25OHD concentration available, 2757 were successfully genotyped. Age and gender-dependent association of SNPs with serum 25OHD concentration was studied in 10 SNPs with previously found association with vitamin D metabolites. Associations of 3 SNPs with serum 25OHD concentration were dependent on age with greater effects on younger (≤60 y) than older (>60 y) adults (rs10783219 in VDR, rs12512631 in GC and rs3794060 in NADSYN1/DHCR7; pinteraction = 0.03, 0.02 and 0.01, respectively). The results suggested a novel association between serum 25OHD concentration and rs8082391 in STAT5B gene in men but not in women (pinteraction = 0.01). After multiple testing correction with false discovery rate method, two age-dependent interactions (rs3794060 in NADSYN1/DHCR7 gene and rs12512631 in GC gene) remained statistically significant. This is the first study to suggest that genetic regulation of serum 25OHD concentration is age-dependent. Our results also indicated a novel association between serum 25OHD concentration and SNP in STAT5B gene in men. The results need to be confirmed in future studies preferably in a larger sample.

Abstract
Genome-wide association studies (GWAS) have identified >250 loci for body mass index (BMI), implicating pathways related to neuronal biology. Most GWAS loci represent clusters of common, noncoding variants from which pinpointing causal genes remains challenging. Here we combined data from 718,734 individuals to discover rare and low-frequency (minor allele frequency (MAF) < 5%) coding variants associated with BMI. We identified 14 coding variants in 13 genes, of which 8 variants were in genes (ZBTB7B, ACHE, RAPGEF3, RAB21, ZFHX3, ENTPD6, ZFR2 and ZNF169) newly implicated in human obesity, 2 variants were in genes (MC4R and KSR2) previously observed to be mutated in extreme obesity and 2 variants were in GIPR. The effect sizes of rare variants are ~10 times larger than those of common variants, with the largest effect observed in carriers of an MC4R mutation introducing a stop codon (p.Tyr35Ter, MAF = 0.01%), who weighed ~7 kg more than non-carriers. Pathway analyses based on the variants associated with BMI confirm enrichment of neuronal genes and provide new evidence for adipocyte and energy expenditure biology, widening the potential of genetically supported therapeutic targets in obesity.

Abstract
Physical activity (PA) may modify the genetic effects that give rise to increased risk of obesity. To identify adiposity loci whose effects are modified by PA, we performed genome-wide interaction meta-analyses of BMI and BMI-adjusted waist circumference and waist-hip ratio from up to 200,452 adults of European (n = 180,423) or other ancestry (n = 20,029). We standardized PA by categorizing it into a dichotomous variable where, on average, 23% of participants were categorized as inactive and 77% as physically active. While we replicate the interaction with PA for the strongest known obesity-risk locus in the FTO gene, of which the effect is attenuated by ~30% in physically active individuals compared to inactive individuals, we do not identify additional loci that are sensitive to PA. In additional genome-wide meta-analyses adjusting for PA and interaction with PA, we identify 11 novel adiposity loci, suggesting that accounting for PA or other environmental factors that contribute to variation in adiposity may facilitate gene discovery.

A principal component meta-analysis on multiple anthropometric traits identifies novel loci for body shape. Nat Commun 2016; 7:13357.

Abstract
Large consortia have revealed hundreds of genetic loci associated with anthropometric traits, one trait at a time. We examined whether genetic variants affect body shape as a composite phenotype that is represented by a combination of anthropometric traits. We developed an approach that calculates averaged PCs (AvPCs) representing body shape derived from six anthropometric traits (body mass index, height, weight, waist and hip circumference, waist-to-hip ratio). The first four AvPCs explain >99% of the variability, are heritable, and associate with cardiometabolic outcomes. We performed genome-wide association analyses for each body shape composite phenotype across 65 studies and meta-analysed summary statistics. We identify six novel loci: LEMD2 and CD47 for AvPC1, RPS6KA5/C14orf159 and GANAB for AvPC3, and ARL15 and ANP32 for AvPC4. Our findings highlight the value of using multiple traits to define complex phenotypes for discovery, which are not captured by single-trait analyses, and may shed light onto new pathways.

Abstract
AIM To examine changes in glucose metabolism (fasting and 2-h glucose) during follow-up in people with impaired fasting glucose in comparison with changes in people with isolated impaired glucose tolerance, people with impaired fasting glucose and impaired glucose tolerance combined and people with screening-detected Type 2 diabetes at baseline, among those who participated in a diabetes prevention programme conducted in Finland. METHODS A total of 10 149 people at high risk of Type 2 diabetes took part in baseline examination. Of 5351 individuals with follow-up ≥ 9 months, 1727 had impaired glucose metabolism at baseline and completed at least one lifestyle intervention visit. Most of them (94.6%) were overweight/ obese. RESULTS Fasting glucose decreased during follow-up among overweight/obese people in the combined impaired fasting glucose and impaired glucose tolerance group (P = 0.044), as did 2-h glucose in people in the isolated impaired glucose tolerance group (P = 0.0014) after adjustment for age, sex, medication and weight at baseline, follow-up time and changes in weight, physical activity and diet. When comparing changes in glucose metabolism among people with different degrees of glucose metabolism impairment, fasting glucose concentration was found to have increased in those with isolated impaired glucose tolerance (0.12 mmol/l, 95% Cl 0.05 to 0.19) and it decreased to a greater extent in those with screening-detected Type 2 diabetes (-0.54 mmol/l, 95% Cl -0.69 to -0.39) compared with those with impaired fasting glucose (-0.21 mmol/l, 95% Cl -0.27 to -0.15). Furthermore, 2-h glucose concentration decreased in the isolated impaired glucose tolerance group (-0.82 mmol/l, 95% Cl -1.04 to -0.60), in the combined impaired fasting glucose and impaired glucose tolerance group (-0.82 mmol/l, 95% Cl -1.07 to -0.58) and in the screening-detected Type 2 diabetes group (-1.52, 95% Cl -1.96 to -1.08) compared with those in the impaired fasting glucose group (0.26 mmol/l, 95% Cl 0.10 to 0.43). Results were statistically significant even after adjustment for covariates (P < 0.001 in all models). CONCLUSIONS Changes in glucose metabolism differ in people with impaired fasting glucose from those in people with isolated impaired glucose tolerance, people with impaired fasting glucose and impaired glucose tolerance combined and people with screening-detected Type 2 diabetes.

Abstract
Common health recommendations often incite very little public response, as people instead require individualized information. The purpose of this study was to assess the psychological effects of personal genetic information, provided by different apoE genotypes, as a tool to promote lifestyle changes. This study was a one-year intervention study using healthy adults, aged 20-67 years (n = 107). Their experiences of state anxiety, threat and stage of change were measured three times over a 12 months period. These psychological experiences were assessed, during the genetic information gathering, for three groups: a high-risk group (Ɛ4+, n = 16); a low-risk group (Ɛ4-, n = 35); and a control group (n = 56). The psychological effects of personal genetic risk information were shown to be short-term, although the levels of state anxiety and threat experiences in the high-risk group both remained at a slightly higher level than in the baseline. Threat experiences differed almost significantly (alpha = 0.017) between the Ɛ4+ and Ɛ4- groups (p = 0.034). Information on the apoE genotype impacted the experience of cardiovascular threat; this effect was most intense immediately after genetic feedback was received. However, fears of threat and anxiety may not be an obstacle for using gene information to motivate healthy, stable adults towards making lifestyle changes. Further studies should thus focus on how to utilize genetic screening in prevention of lifestyle-related diseases.

AIM To assess the behavioral effects of receiving personal genetic information, using apoE genotypes as a tool for promoting lifestyle changes. apoE was chosen because it has a significant impact on lipid metabolism and cholesterol absorption, both factors in cardiovascular disease. METHODS This study was a 1-year intervention study of healthy adults aged 20-67 years (n = 107). Their behavioral changes were measured by diet (e.g., fat quality, as well as consumption of vegetables, berries, fruits, and fatty and sugary foods), alcohol consumption, and exercise. Health and taste attitudes were assessed with the Health and Taste Attitude Scales (HTAS). The measurements were performed 4 times: at baseline (T0), as well as 10 weeks (T1), 6 months (T2), and 12 months after baseline (T3). These behavioral effects were assessed for three groups: a high-risk (Ɛ4+; n = 16), a low-risk (Ɛ4-; n = 35), and a control group (n = 56). RESULTS Personal genetic information affected health behavior. Dietary fat quality improved more in the Ɛ4+ group than in the Ɛ4- and control groups after personal, genotype-based health advice. This change differed significantly between the Ɛ4+ and the control group (p < 0.05), but only for a short time. CONCLUSION Personal genetic information, based on apoE, may affect dietary fat quality. More research is required to determine how to utilize genotype-based health information and how to efficiently achieve long-term changes in the prevention of lifestyle-related diseases.

Abstract
Pneumonia is recognised in patients suffering from acute cough or deteriorated general condition. Patients with acute cough without pneumonia-related symptoms or clinical findings do not benefit from antimicrobial treatment. Those with suspected or confirmed pneumonia are treated with antibiotics, amoxicillin being the first choice. Most patients with pneumonia can be treated at home. Those with severe symptoms are referred to hospital. Patients are always encouraged to contact his/her physician if the symptoms worsen or do not ameliorate within 2-3 days. Patients aged 50 years or older and smokers are controlled by thoracic radiography in 6-8 weeks.

Abstract
AIMS The purpose of this study was to assess whether changes in self-rated physical activity and diet during a type 2 diabetes (T2D) prevention program were associated with changes in estimated 10-year risk for cardiovascular disease (CVD) events and mortality in people at high risk for T2D. METHODS Individuals were identified and offered lifestyle counseling as part of the Finnish diabetes prevention program. Ten-year risk for estimated CVD events and mortality were calculated with Framingham Risk Score (FRS) and Systematic Coronary Risk Evaluation (SCORE) formula. FRS was available for 774 men and 1474 women and SCORE for 961 men and 1766 women. RESULTS During the one-year follow-up, 9.6% of the men reported both an increase in physical activity and improved dietary pattern, 4.1% an increase in physical activity, 39.3% an increase in improved dietary pattern, while 47.0% reported no lifestyle changes. Corresponding numbers for women were 14.2%, 3.8%, 39.2% and 42.7%. Estimated 10-year risk for CVD events decreased 3.5% in men and 1.5% in women reporting an increase in physical activity and improvement in diet, compared to an increase of 0.15% in men (p<0.001, between groups) and decrease of 0.43% (p=0.027, between groups) in women with no lifestyle changes after adjustment for age and baseline FRS. Numbers needed to treat to prevent one CVD event by lifestyle changes were 25 for men and 59 for women. Lifestyle changes had no effect on estimated CVD mortality risk. CONCLUSIONS Lifestyle counseling offered in primary health care for one year results in favorable changes in lifestyle, and lowered the estimated 10-year risk for CVD events.

Abstract
BACKGROUND Studies using traditional measures of socio-economic position, such as education, income and occupation, have found inequalities in depressive symptoms, but less is known about the association between financial satisfaction and depressive symptoms. AIMS To examine the association of depressive symptoms with financial satisfaction in Finnish adults in a population-based cross-sectional FIN-D2D survey. METHODS Four thousand, five hundred randomly selected individuals aged 45-74 years were invited to the study. Participation rate for health examinations was 64%. Complete information on depressive symptoms and financial satisfaction was available for 2,819 individuals. Financial satisfaction was asked using a questionnaire. Depressive symptoms were measured by Beck Depression Inventory (≥ 10) and/or use of antidepressants. RESULTS Altogether 11.6% of individuals who were satisfied with their financial situation had depressive symptoms. Corresponding figures for individuals who were somewhat satisfied or dissatisfied were 20.6% and 42.6%, respectively. Individuals who were less satisfied with their financial situation were more likely to suffer from depressive symptoms even after adjusting for gender, age, marital status, number of chronic diseases, smoking, binge drinking, physical activity, education and household income. CONCLUSIONS Instead of more traditional measures of socio-economic position, financial dissatisfaction seems to be associated with depressive symptoms in Finnish adults.

Abstract
In this study, the authors analyzed whether chronotypes, sleep duration, and sleep sufficiency are associated with cardiovascular diseases and type 2 diabetes by using the National FINRISK Study 2007 data (N = 6258), being a representative sample of the population aged 25 to 74 living in five areas of Finland. Health status assessments and laboratory measurements from the participants (N = 4589) of the DILGOM substudy were used for the detailed analysis of chronotype. Evening types had a 2.5-fold odds ratio for type 2 diabetes (p < .01) as compared with morning types, the association being independent of sleep duration and sleep sufficiency. Evening types had a 1.3-fold odds ratio for arterial hypertension (p < .05 after controlling for sleep duration or sleep sufficiency), a faster resting heart rate and a lower systolic blood pressure (both p < .01), and lower levels of serum total cholesterol and low-density lipoprotein cholesterol (both p < .0001) than morning types. There were significant 1.2- to 1.4-fold odds ratios for arterial hypertension among those with long or short sleep durations or reduced sleep sufficiency. To conclude, the behavioral trait towards eveningness is suggested to predispose individuals to type 2 diabetes in particular, whereas compromised sleep is robustly associated with arterial hypertension.

Abstract
AIMS To investigate whether a positive family history of diabetes is associated with the effectiveness of lifestyle counselling on cardio-metabolic risk factors and glucose tolerance status in a 1-year follow-up in a cohort of Finnish men and women at high risk for Type 2 diabetes. METHODS Altogether, 10,149 individuals who had high risk of Type 2 diabetes participated in the implementation programme of the national diabetes prevention programme at baseline. One-year follow-up data were available for 2798 individuals without diabetes. Family history of diabetes was based on self-report. Lifestyle interventions were individual or groups sessions on lifestyle changes. The effectiveness of lifestyle intervention was measured as changes in cardiovascular risk factors, glucose tolerance status and incidence of Type 2 diabetes. RESULTS Family history was associated with the effectiveness of lifestyle intervention in men, but not in women. During the 1-year follow-up, body weight, BMI, systolic blood pressure, total cholesterol, LDL cholesterol and score for 10-year risk for fatal cardiovascular disease (SCORE) decreased and glucose tolerance status improved more in men without a family history of diabetes than in men with a family history of diabetes. Of the participating men and women, 10% and 5% developed Type 2 diabetes, respectively. Family history was not related to the incidence of Type 2 diabetes in either gender. CONCLUSIONS Men without a family history of diabetes were more successful in responding to lifestyle counselling with regard to cardio-metabolic measurements and glucose tolerance than those with a family history of diabetes. Similar results were not seen in women. In keeping with findings from earlier studies, the prevention of Type 2 diabetes is not influenced by a family history of diabetes.

Abstract
OBJECTIVES To examine whether the use of statins is associated with the incidence of type 2 diabetes (T2D) and changes in glucose metabolism among individuals at high risk for T2D participating in 1-year lifestyle intervention in primary healthcare setting. DESIGN Prospective follow-up study. SETTING In all, 400 primary healthcare centres and occupational healthcare clinics in Finland. PARTICIPANTS We screened altogether 10 149 individuals at increased risk for T2D; of these, 2798 non-diabetic individuals verified by a 2 h glucose tolerance test participated in the 1-year follow-up. INTERVENTIONS Lifestyle intervention (individual and/or group-based counselling). PRIMARY OUTCOME MEASURES Incidence of T2D and fasting and 2 h glucose measured at baseline and follow-up. RESULTS A total of 484 individuals (17.3%) used statins at the baseline. Of them 31 (7.5%) developed T2D during the follow-up, compared to 126 (6.5%) of statin non-users (OR 1.17, 95% CI 0.78 to 1.76, p=0.442). Interestingly, fasting glucose increased by 0.08 mmol/l in statin users, but remained unchanged in non-users, the difference being 0.074 mmol/l (95% CI 0.014 to 0.134) and remained significant even after adjustment for age, sex, baseline fasting glucose, the presence of cardiovascular disease (CVD), use of antihypertensive and/or coronary artery disease medication, weight and 1-year weight change (adjusted p=0.042). CONCLUSIONS The incidence of T2D did not differ between the statin users and non-users. The finding that fasting glucose slightly increased in statin users in spite of lifestyle interventions suggests the view that the use of statins might have unfavourable effects on glucose metabolism and that statins might hamper beneficial effects of lifestyle intervention in people at high risk of T2D.

Abstract
OBJECTIVE In this FIN-D2D cross-sectional survey the relationship of age with HbA(1c) and fasting and 2h glucose in the oral glucose tolerance test (OGTT) was explored in apparently randomly selected healthy population. PATIENTS AND METHODS The glycaemic parameters were measured in 1344 men and 1482 women (aged 45-74 years), and among them we excluded all subjects with known diabetes, hypertension or dyslipidaemia. The final analyses for HbA(1c) and the ratios of fasting glucose/HbA(1c) and 2h glucose/HbA(1c) included 649 men and 804 women. RESULTS Mean age was 57 years and BMI 26.1kg/m(2) for both genders. HbA(1c) increased in both genders with age (p<0.001). For a particular fasting glucose level HbA(1c) level was higher in older age groups (p<0.001 for linearity). By contrast, a particular 2h plasma glucose value in OGTT implied significantly lower HbA(1c) in the elderly (p<0.001 for linearity). CONCLUSION In apparently healthy population, screened with OGTT, in older individuals compared with younger ones a particular HbA(1c) value implies slightly lower fasting glucose, but relatively higher 2h glucose. These results need to be verified in different populations. The effects of age on relation between HbA(1c) and plasma glucose should be taken into account in classifying people into different dysglycaemia categories.

Abstract
AIMS Lifestyle intervention is effective in prevention of type 2 diabetes (T2D) in high-risk individuals. However, health behaviour and health outcomes are modified by socioeconomic position through various mechanisms. It is therefore possible that success in lifestyle intervention may be determined by factors such as level of education or occupation. In this study we assessed the impact of the level of education and occupation on the baseline anthropometric and clinical characteristics and their changes during a one-year follow-up in a cohort of Finnish men and women at high risk for T2D aged 20-64 years. METHODS As part of a Finnish national diabetes prevention programme 2003-2007 (FIN-D2D), high-risk individuals were identified using opportunistic screening for lifestyle intervention in primary health care. 1,067 men and 2,122 women had one-year follow-up data. Education and occupation were used as factors of socioeconomic position. Measures of anthropometric and clinical characteristics included weight, body mass index (BMI), waist circumference, systolic and diastolic blood pressure, total, HDL and LDL cholesterol, triglycerides, FINDRISC scores and glucose tolerance status. RESULTS The effect of intervention was similar in all socioeconomic groups, but the level of education was related to glucose tolerance status in both genders. In addition, socioeconomic differences existed in blood pressure, weight, BMI, waist circumference and HDL cholesterol. CONCLUSIONS Socioeconomic position did not seem to have any impact on the effectiveness of lifestyle intervention in individuals at high risk for T2D, which is encouraging from the point of view of reducing health inequalities.

Population-level effects of the national diabetes prevention programme (FIN-D2D) on the body weight, the waist circumference, and the prevalence of obesity. BMC Public Health 2011; 11:350. [PMID: 21595955 PMCID: PMC3118241 DOI: 10.1186/1471-2458-11-350] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2010] [Accepted: 05/19/2011] [Indexed: 11/30/2022] Open
Abstract
Background The implementation project of the national diabetes prevention programme in Finland, FIN-D2D, was carried out in primary health care in the area of five hospital districts during 2003-2007. Methods The population strategy of FIN-D2D was primarily aimed at increasing the awareness of type 2 diabetes and preventing obesity. To investigate the effects of this strategy, we studied the changes in the prevalence of obesity, overweight, and central obesity among a random independent sample of individuals aged 45-74 years in the FIN-D2D area; and assessed whether they differed from a sample of individuals in the control area, which consisted of four geographical areas not participating in FIN-D2D (FINRISK study). Data was obtained for 5850/ 6406 (in the beginning/ in the end) individuals. The duration of the observation period varied from three to five years. Results The mean body weight decreased from 78.7 to 78.1 kg (p = 0.041) in the FIN-D2D area, and from 78.7 to 78.0 kg (p = NS) in the control area. The prevalence of obesity (BMI ≥30 kg/m2) decreased in the FIN-D2D area (26.5% vs. 24.4%, p = 0.015), and in the control area (28.4% vs. 25.2%, p = 0.005). The prevalence of morbid obesity (BMI ≥40 kg/m2) remained unchanged in the FIN-D2D area, but increased in the control area (1.2% vs. 2.3%, p = 0.007). The mean waist circumference remained unchanged in the FIN-D2D area, but increased in the control area (92.8 vs. 94.0 cm, p = 0.005). Conclusions The prevalence of obesity may be decreasing among 45-74 year old Finns. We still need a longer time perspective and future studies to see whether this favourable trend can be sustained in Finland. The actions of this implementation project can at least partly explain the differences in the mean waist circumference and the prevalence of morbid obesity between the intervention and control areas.

Abstract
OBJECTIVE To study the association between impaired glucose regulation (IGR), screen-detected type 2 diabetes, and previously known diabetes and depressive symptoms. RESEARCH DESIGN AND METHODS Altogether, 2,712 participants from three hospital districts in Finland attended a health examination. Cutoff scores ≥10 and ≥16 in the 21-item Beck Depression Inventory (BDI-21) were used for depressive symptoms. The participants were defined as having known diabetes if they reported diabetes. An oral glucose tolerance test was used to detect normal glucose regulation (NGR), impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and screen-detected diabetes. The participants were defined as having IGR if they had IFG or IGT. RESULTS Prevalence of depressive symptoms, defined as a BDI-21 cutoff score ≥10, was 14.4% for those with NGR, 13.7% for those with IGR, 14.8% for those with screen-detected diabetes, and 26.4% for those with previously known diabetes. The corresponding prevalences for a cutoff score ≥16 were 3.4, 3.4, 4.2, and 7.5%, respectively. Compared with NGR and adjusted for demographic, lifestyle, and biological factors, the odds ratios for IGR, screen-detected diabetes, and previously known diabetes were 0.91 (95% CI 0.69-1.20), 0.70 (0.45-1.08), and 1.35 (0.84-2.15), respectively, for a cutoff score ≥10. For a cutoff score ≥16, the corresponding odds ratios were 1.05 (0.62-1.76), 0.87 (0.40-1.90), and 1.56 (0.69-3.50), respectively. CONCLUSIONS Participants with diagnosed diabetes had a higher prevalence of depressive symptoms than participants with NGR, IGR, and previously unknown diabetes. When potential confounding factors were included in the analysis, previously known diabetes was not significantly associated with depressive symptoms.

Abstract
OBJECTIVES The aims were to evaluate the profile of newly diagnosed adult asthma cases and the approach adopted to the secondary care management at the launch of the Finnish asthma programme in 1994 and seven years later, in 2001. METHODS A retrospective medical record audit was made of non-acutely referred patients with asthma in 1994 (n=165) and in 2001 (n=133). Clinical profile data, numbers of out-patient visits and periods of in-patient care before and after asthma diagnosis were gathered from referral letters and secondary care records. RESULTS The newly diagnosed asthma patients in 2001 were older, more obese and had more co-morbidities. The main asthma symptoms, such as dyspnoea, wheezing and cough, occurred equally in both years but were more often periodic than daily in 2001. Wheezing during auscultation was significantly less common in 2001. The diagnostic process was associated to a history of asthma in first-degree relatives (OR 5.34, 95% CI 1.12-24.49) in 1994 and a visit to a nurse prior to that to a physician (OR 3.13, 95% CI 1.17-8.37) in 2001. Secondary care visits per new case of asthma (7.3 in 1994 vs. 5.4 in 2001) and days in hospital (3.6 in 1994 vs. 0.95 in 2001) decreased significantly. CONCLUSIONS The profile of asthma diagnosed in secondary care indicates milder disease with more co-morbidities in 2001 than in 1994.Trends towards assigning a more active role on the part of primary care physicians and more rational use of secondary care resources in the management of asthma were found.

Abstract
Background There is a worldwide increase in the prevalence of obesity and disturbances in glucose metabolism. The aim of this study was to assess the current prevalence of obesity, central obesity and abnormal glucose tolerance in Finnish population, and to investigate the associations between body mass index (BMI), waist circumference and abnormal glucose tolerance. Methods A cross-sectional population-based survey was conducted in Finland during October 2004 and January 2005. A total of 4500 randomly selected individuals aged 45–74 years were invited to a health examination that included an oral glucose tolerance test. The participation rate was 62% in men and 67% in women. Results The prevalence of obesity was 23.5% (95% Confidence Interval (CI) 21.1–25.9) in men, and 28.0% (95% CI 25.5–30.5) in women. The overall prevalence of abnormal glucose tolerance (including type 2 diabetes, impaired glucose tolerance, or impaired fasting glucose) was 42.0% (95% CI 39.2–44.8) in men and 33.4% (95% CI 30.9–36.0) in women. The prevalence of previously unknown, screen-detected type 2 diabetes was 9.3% (95% CI 7.7–11.0) in men and 7.3% (95% CI 5.9–8.7) in women. Central obesity was associated with abnormal glucose tolerance within each of the three BMI categories normal (< 25 kg/m2), overweight (25–29 kg/m2), and obese (≥ 30 kg/m2). Conclusion In a population-based random sample of Finnish population, prevalences of obesity, central obesity and abnormal glucose tolerance were found to be high. A remarkably high number of previously undetected cases of type 2 diabetes was detected. Waist circumference is a predictor of abnormal glucose tolerance in all categories of obesity.

Abstract
AIMS To investigate whether leisure time physical activity (LTPA) characteristics differ between individuals with previously undiagnosed (screen-detected) and those with previously diagnosed (known) type 2 diabetes. METHODS A population-based random sample of 1364 (participation rate 61%) men and 1461 (65%) women aged 45-74 years participated in a cross-sectional health examination including an oral glucose tolerance test and physical activity assessment by a self-administered questionnaire. RESULTS Women with screen-detected type 2 diabetes (n=110) were physically less active than those with known type 2 diabetes (n=68) with differences in the duration of physical activity sessions (multivariate-adjusted P=0.041) and the number of moderate to high intensity exercise sessions per week (multivariate-adjusted P=0.007). In men no differences in LTPA were observed between individuals with screen-detected (n=126) and with known type 2 diabetes (n=109). CONCLUSIONS This study supplies indirect evidence that in women, but not in men, with diagnosed type 2 diabetes exercise counselling or other treatment related factors produces the desired increase in LTPA.

Abstract
AIM To determine the association between sleep-disordered breathing (SDB) and obesity, diabetes and glucose intolerance among middle-aged men and women in Finland. METHODS A multicentre, population-based, cross-sectional survey in Finland. A total of 1396 men and 1500 women aged 45-74 years participated in the survey between 2004 and 2005. The study subjects underwent a health examination including an oral glucose tolerance test and filled a questionnaire describing their sleep habits. RESULTS Middle-aged men with SDB had an increased prevalence of diabetes and abnormal glucose tolerance. These associations were not found among middle-aged women. After adjustments for age, body mass index, smoking and central nervous system-affecting medication, SDB was independently associated with diabetes and glucose intolerance in men, but not in women. CONCLUSION Middle-aged men with SDB have an independent risk of type 2 diabetes. However, both diabetes and SDB exhibit a strong association with obesity and especially with central obesity, reflecting increased visceral fat. In clinical practice especially male patients with diabetes should always be asked about habitual snoring and about possible sleep apnoea.

Abstract
BACKGROUND Most cohort studies have found depressive symptoms to be associated with increased cardiovascular mortality in the elderly, but follow-up times have often been short and study populations small. OBJECTIVES To describe associations between stronger symptoms of depression and the risk of death from coronary heart disease (CHD) or myocardial infarction (MI) in elderly Finnish subjects free of CHD at the baseline. METHODS This study is a prospective population-based epidemiological and clinical twelve-year follow-up study in Lieto Health Centre, Finland. The basic population consisted of 1196 elderly (64 years of age or older) persons who lived in the municipality of Lieto in southwestern Finland in 1990. The occurrence of CHD was determined on the basis of electrocardiographic (ECG) findings, Rose questionnaire and the diagnoses in medical records. The persons with CHD were excluded from the study population. Symptoms of depression at the baseline were measured with the Zung Self-rating Depression Scale (ZSDS). Mortality was followed up for about 12 years. RESULTS The Kaplan-Meier survival curves showed stronger symptoms of depression to be related to high risks of mortality from CHD or MI among men and women. According to the Cox model for men significant predictors for higher risk of CHD or MI mortality were stronger symptoms of depression, higher age and a large number of medications in use. When women were examined, significant predictors were stronger symptoms of depression and a large number of medications in use. CONCLUSIONS Stronger symptoms of depression are an independent risk factor for high CHD or MI mortality in aged Finnish men and women free of CHD at baseline.

Abstract
OBJECTIVE To examine the association between sleep duration with type 2 diabetes and abnormal glucose tolerance among middle-aged men and women in Finland. METHODS The FIN-D2D survey is a population-based cross-sectional multicentre study in Finland, with 1336 men and 1434 women aged 45-74 participating in the survey during 2004 and 2005. A health examination including an oral glucose tolerance test and sleep questionnaire was performed for all participants. RESULTS There was an independent association between abnormal sleeping times and type 2 diabetes in middle-aged women. Even after adjustments for age, body mass index, sleep apnea probability, smoking, physical activity, and central nervous system-affecting medication, sleep duration of 6h or less or 8h or longer was independently associated with type 2 diabetes. There was no increase in the prevalence of diabetes in middle-aged men with abnormal sleeping times. CONCLUSION Short (< or = 6h) or long (> or = 8h) sleep duration is related to an increased risk of type 2 diabetes in middle-aged women but not in men.

Asthma Programme in Finland: high consensus between general practitioners and pulmonologists on the contents of an asthma referral letter. PRIMARY CARE RESPIRATORY JOURNAL : JOURNAL OF THE GENERAL PRACTICE AIRWAYS GROUP 2007; 13:205-10. [PMID: 16701670 PMCID: PMC6750692 DOI: 10.1016/j.pcrj.2004.04.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 01/09/2004] [Accepted: 04/09/2004] [Indexed: 11/29/2022]
Abstract
AIMS The purpose of the present study was to define quality criteria for an asthma referral letter using a national co-operative effort between general practitioners and pulmonologists. METHODS A consensus-seeking expert panel representing primary and secondary health care merged evidence from the literature and existing national and local asthma programmes to produce 19 provisional criteria to be included in an asthma referral letter. These criteria were contained within a national questionnaire review which was sent out to groups of Finnish physicians. The target groups for the review were all chief pulmonologists in specialist care (n = 32), and representatives of all Finnish health centres (n = 283) - either the chief physician (n = 143) or the local asthma co-ordinating physician (n = 140). RESULTS The overall response rate to the national questionnaire study was 75%. The three groups of responding physicians had very similar gradings on the necessity of the 19 provisional criteria, most of which were considered very necessary. 14 final disease-specific criteria for an asthma referral letter were derived as a result of this study. CONCLUSION The main result of this study is an agreed data set of essential information that needs to be included in an asthma referral letter. Importantly these criteria were developed by general practitioners and pulmonologists together.

Abstract
AIMS AND OBJECTIVES The Finnish National Asthma Programme, which was launched in year 1994, considered the management of asthma as a community problem. The role of the primary health care in the management of asthma was emphasized. Optimal asthma management includes good communication between health care professionals. Referral letters are an accepted tool for evaluation of the communication process. The aim of this study was to assess the quality of asthma-related referral letters. METHODS All non-acute referral letters (n=3176) to three pulmonary departments were screened in 2001 and all those related to asthma were included (n=1289). The 14 previously derived asthma-specific criteria were applied: occupation, smoking, known allergies, current medication, other diseases, onset of symptoms, wheezing, dyspnoea, specified dyspnoea, cough, specified cough, use of asthma medication, peak-flow follow-up or spirometry with bronchodilatation test as an attachment. The study group was prepared to accept the maximum of 30% of the referral letters to be of poor quality. RESULTS Twenty-one per cent of the referral letters were graded good, 34% satisfactory and 45% poor. Information on wheezing, smoking habits and current medication was mentioned in 44%, 42% and 41% of asthma letters respectively. CONCLUSIONS The Finnish National Asthma Programme calls for optimizing communication between doctors. The proportion of poor letters was 50% higher than the preset standard and clearly indicates a need for improvement. We found several issues, which need to be better communicated (smoking, lung function tests, wheezing, medication) when referring a patient with suspected asthma.

Abstract
OBJECTIVE To compare medication use in patients suffering from cardiovascular disease with and without dementia. SUBJECTS All inhabitants aged 75 and older in Lieto, Finland (n = 462, participation rate 82%). MEASUREMENTS Direct standardised assessments of dementia and cardiovascular diseases. Quantification of drug use by self-report and by prescription and drug container checks. RESULTS In multivariate analyses, the odds ratio for demented cardiovascular patients receiving any cardiovascular medication (use vs. non-use) was 0.31 (95% confidence interval 0.12-0.82). Compared to the non-demented, demented stroke patients were treated less often with antithrombotic agents (p = 0.041) and demented hypertensive patients less often with beta-blockers (p = 0.045). CONCLUSION Demented cardiovascular patients, even mildly to moderately demented, were prescribed fewer evidence-based cardiovascular medications than non-demented patients.

Abstract
In a nationwide study, we identified a total of 59 patients diagnosed with primary pulmonary hypertension (PPH) in Finland between the years 1987 and 1999. These data support a minimum estimate for a PPH population prevalence of 5.8 cases/million with an incidence of 0.2-1.3 cases/million/year. The male-to-female ratio among the patients was 1:4, while 7% (4/59) of the PPH probands had a known family history of the disorder. Familial or sporadic PPH showed no geographic clustering to any region of Finland. Sequencing of the coding regions and exon-intron boundaries of the bone morphogenetic protein receptor type 2 (BMPR2) identified heterozygous BMPR2 mutations in 12% (3/26) of the sporadic and 33% (1/3) of the familial patients. All four mutations were different, and two of those have been previously reported in other populations. Pathogenic defects in BMPR2 include a novel missense mutation (c.2696G>C encoding R899P), located within the receptor intracellular cytoplasmic domain whose function has been poorly characterized. Our analysis demonstrates that this mutant, while localizing to the cell surface, does not impact on SMAD-mediated (mothers against decapentaplegic homolog) intracellular signaling, but leads to constitutive activation of the p38(MAPK) pathway. The absence of a founder mutation in a genetically homogeneous population, such as the Finns, suggests that all identified BMPR2 mutations have to be rather young while the ancestral (if any) mutations have been lost either due to repetitive genetic bottlenecks or due to significant negative selection.

Abstract
OBJECTIVE To study undiagnosed diseases in older people with and without dementia. DESIGN Cross-sectional population-based study in Lieto, southwestern Finland. PARTICIPANTS All the inhabitants aged 64 and more in Lieto. Participation rate was 82% (n = 1,260). MEASUREMENTS Dementia and its subtypes were diagnosed according to prevailing criteria. Medical conditions were assessed in clinical examinations and from medical records. RESULTS 112 patients with dementia were found; 66% of them had at least 1 undiagnosed disease compared to 48% of the non-demented group (p = 0.041). The demented subjects had more undiagnosed hypercholesterolaemia (p = 0.039) and undiagnosed hypothyroidism (p = 0.032) than the controls. CONCLUSION Undiagnosing is more common among patients with dementia. Screening strategies should be developed further to find these patients.

Abstract
OBJECTIVE To characterise the prevalence of, and changes in, coronary heart disease (CHD) among men and women aged between 64 and 71 years in the 1990s. DESIGN A study of clinical epidemiology involving two cohorts of elderly persons in 1990-1991 and 1998-1999. SETTING Primary health care in the municipality of Lieto in southwestern Finland. SUBJECTS Persons between 64 and 71 years of age in the southwest of Finland in 1990-1991 and 1998-1999. MAIN OUTCOME MEASURES The occurrences of CHD were estimated using the history of a previous myocardial infarction or coronary revascularisation procedure evident in the medical records and with ischaemia or infarction as established on ECG according to the Whitehall criteria. RESULTS The prevalence of 'probable' CHD decreased among men and women aged between 64 and 71 years, whereas the prevalence of 'possible' CHD decreased among women alone. Silent myocardial infarctions were common among women of both cohorts. Many more men of the second cohort, compared to the first one, had undergone a coronary angioplasty or bypass operation. CONCLUSION The prevalence of CHD decreased among elderly women more clearly than among young elderly men. The favourable development illustrating a decrease in the prevalence of CHD among women should be sustained, while health promotion activities will need to be directed more actively towards men.

Abstract
BACKGROUND The purpose of this study was to analyse the association of ambulatory blood pressure (ABP) to left ventricular mass (LVM) in a population aged over 64 years and to describe the level of ABP in subjects with and without left ventricular hypertrophy (LVH) in older age. METHODS ABP measurement and echocardiography for calculation of LVM were assessed in 490 inhabitants (mean age 70.7 years, range 64-87 years) of a small town in southwestern Finland who were able to visit an outpatient clinic. Explanatory factors associated with LVM were assessed with linear regression analysis. LVH was defined as calculated LVM-index values exceeding 150 g/m2 in men and 120 g/m2 in women adopted from the Framingham Study. RESULTS Systolic ABP was significantly associated with LVM. No correlation between diastolic ABP and LVM was found. Other factors independently related to LVM were gender, body mass index and age. The prevalence of echocardiographic LVH was 22%. Subjects with LVH had markedly higher systolic ABP levels than those without LVH (mean (SD) 24-h ABP: 132(16)/75(8) mmHg vs. 123(13)/75(8) mmHg). CONCLUSION Systolic ABP is associated with LVM in older people. In addition, systolic ABP is superior to diastolic ABP in relation to LVM in the aged.

Abstract
This double-masked, placebo-controlled study was undertaken to determine the efficacy and safety of oral clodronate in the prevention of bone loss in early postmenopausal women with vertebral osteopenia. Altogether 610 women with a mean age of 53 years were recruited for the study. They were 1-5 years postmenopausal and their lumbar spine bone mineral density (BMD) was at least 1 standard deviation below the mean of premenopausal women ( T-score < or =-1). The subjects were randomized into five study groups to receive either placebo, clodronate 65 mg, 400 mg or 800 mg daily, or intermittent clodronate in 3 month cycles with 400 mg daily for 15 days followed with no treatment for 75 days for 3 years. One hundred and eighty-seven of 509 women who completed the primary study continued in the extension study of 2 years in which previous placebo users were switched to clodronate 800 mg daily, while previous users of 400 mg or 800 mg of clodronate used either placebo or 800 mg of clodronate daily. In the primary study clodronate was administered in the evening, and in the extension 1 h before breakfast on an empty stomach. In the primary study mean changes in lumbar spine BMD were -3.4% in the placebo group and +0.4% in 800 mg clodronate group [difference between groups at 3 years 3.8% (95% CI 2.7% to 4.9%, p<0.0001)], and in the trochanter area BMD -1.1% in the placebo group, and + 0.4% in the 800 mg clodronate group [difference between groups at 3 years 1.5% (95% CI 0.05% to 2.9%)]. During the extension study mean changes in lumbar spine BMD were +1.5% in the clodronate group and -0.2 % in the placebo group [difference between groups 1.7% (CI 0.4% to 3.0%, p = 0.010)] and in trochanter BMD were +2.5% in the clodronate group and no change in the placebo group [difference between groups 2.1% (CI 0.3% to 3.9%, p = 0.007)]. No statistically significant differences between the placebo and 800 mg clodronate groups were found in the femoral neck BMD. In the primary study the urinary excretion of type I collagen aminoterminal telopeptide (NTX) decreased by 44% ( p<0.0001 compared with placebo) and that of deoxypyridinoline by 18% ( p<0.0001) in the clodronate 800 mg group. In the extension study urinary NTX decreased by 51% ( p<0.0001) in those who were switched to 800 mg of clodronate and increased by 67% ( p<0.0001) in those who stopped using that dose. There was no difference in the frequency of gastrointestinal complaints between clodronate- and placebo-treated patients in the primary study, but they were more common among women who received clodronate in the extension phase. Clodronate in daily doses of 400-800 mg caused a slight elevation of aminotransferase levels, usually within the reference range. In bone biopsies no defect in mineralization was found. In conclusion, clodronate in a daily dose of 800 mg prevents early postmenopausal bone loss at the sites of the skeleton in which cancellous bone predominates. It effectively reduces bone resorption and bone turnover rate. Antifracture efficacy of clodronate remains to be established by prospective, placebo-controlled trials.

Abstract
BACKGROUND Coronary heart disease (CHD) and decline in cognitive functioning and dementia are common problems in the elderly. Cardiovascular diseases (CVDs) are connected with vascular dementia, but less is known about cognitive functioning among elderly patients with CHD based on population studies. OBJECTIVE To describe the associations between CHD and cognitive impairment among the elderly. POPULATION AND METHODS Of the total population of the Lieto study (488 community-dwelling men and 708 women, >/=64 years old), the ambulatory patients with CHD (89 men and 73 women) and sex- and age-matched controls without any sign of CHD (178 men and 146 women) were selected to make up the study population. CHD was defined as the presence of angina pectoris or a past myocardial infarction. Cognitive assessment was based on the Mini-Mental State Examination (MMSE). RESULTS The total MMSE scores, the MMSE subtest scores and the overall test-based cognitive functioning did not differ between patients and controls. Among men, higher MMSE subscores in orientation and language were related to more severe chest pain. According to logistic regression analyses, the cognitive impairment of men was associated with high age, the use of cardiac glycosides and physical disability. Among women, cognitive impairment was associated with high age and the use of antipsychotics. CONCLUSION In general, CHD has no independent association with cognitive impairment among the non-institutionalized community-living elderly. Among men, however, a complicated CHD may negatively affect cognitive functioning.

Abstract
The importance of early initiation of inhaled steroids even in mild asthma has been documented in several studies. It is not, however, clear whether the treatment should be started with a high or a low dose of the inhaled steroid. We have compared the effects of high and low dose inhaled steroid, budesonide, in patients with newly detected asthma. We studied 101 adult patients with newly detected bronchial asthma who were without inhaled steroid or any regular pharmacological treatment for their asthma. The patients were randomly allocated to two treatment groups: one to receive 800 microg inhaled budesonide per day and the other to receive 200 microg inhaled budesonide per day. The drugs were given with a Turbuhaler dry powder inhaler. During the 3-month treatment period, no significant differences between the treatment groups were noted in morning or evening PEF values, in spirometric parameters, in asthmatic symptoms or in the use of rescue beta2-agonists. The decrease in bronchial hyperresponsiveness was, however, more marked in the high dose budesonide group, reaching a borderline significance (P=0.10 high vs. low dose budesonide). In addition, in serum markers of asthmatic inflammation significant differences were shown between the treatment groups. The decrease in the number of blood eosinophils during the treatment was more marked in the high dose budesonide group (P=0.02; high vs. low dose budesonide). In serum ECP no change was observed in the low dose budesonide group, but a marked decrease in the high-dose budesonide group (P=0.008; high vs. low dose budesonide). The change was even more marked with regard to serum EPX (P=0.005; high vs. low dose budesonide). Our results support the view that the treatment of newly detected asthma should be started with a high dose of inhaled steroid. The low dose may not be enough to suppress asthmatic inflammation despite good clinical primary response.

Abstract
OBJECTIVE to study the prevalence of coronary heart disease (CHD) and its clinical manifestations among Finnish elderly people in a cross-sectional epidemiological survey in the rural district of Lieto, southwestern Finland, with special emphasis on the overlap of CHD manifestations with electrocardiogram (ECG) findings and factors associated with CHD. DESIGN observational population-based study. SETTING Health Centre in Lieto, Finland, 1990-91. SUBJECTS 488 men and 708 women aged 64-97 years. MAIN OUTCOME MEASURES angina pectoris (AP) and dyspnoea were recorded using the London School of Hygiene cardiovascular questionnaires. Resting ECG findings were analysed and coded. Minnesota codes 1.1-1.3, 4.1-4.4, 5.1-5.3 or 7.1 were interpreted as ischaemic. The medical history of cardiovascular diseases was based on medical records. RESULTS the prevalence of AP was 9.1% [95% confidence interval (CI): 6.7-12.0] among men and 4.9% (3.5-6.8) among women. The respective figures for myocardial infarction (MI) were 13.9% (10.9-17.0) and 6.5% (4.8-8.6). Ischaemic ECG findings were common: 32.9% (28.7-37.1) of men and 39.3% (35.7-43.0) of women had such changes, whereas only a minority of them reported typical AP. The total prevalence of CHD, including AP, MI, past coronary artery by-pass operation or angioplasty or ischaemic ECG findings, was 37.7% (33.4-42.0) in men and 42.0% (38.3-45.6) in women. Among men, a higher prevalence of CHD was associated with increasing age [odds ratio (OR) 1.81; 95% .CI: 1.20-2.73] and a history of having smoked in the past (OR 1.66; 1.06-2.59), whereas among women it was associated with increasing age (OR 2.02; 1.48-2.77) and a lower educational level (OR 2.30; 1.37-3.86). CONCLUSION the prevalence of CHD among elderly people is high and the clinical picture of the disease is variable. The nature of CHD seems to be less severe among elderly women compared with men. Minor ECG changes, especially in the ST and T segments, are common with ageing and should not necessarily be interpreted as ischaemic. However, these findings combined with atypical chest pain or dyspnoea in an elderly person may indicate the possibility of CHD.

Abstract
Clodronate is a novel drug used for inhibiting osteoclastic activity. The aim of the present double-blind study was to evaluate the efficacy and tolerability of clodronate (Leiras, Finland) in corticosteroid-induced bone loss among asthmatic patients. Seventy-four adult patients (41 women and 33 men, mean age 57.3 years) having a long history (mean 8.1 years) of oral and inhaled corticosteroid therapy were randomized to four parallel treatment groups: clodronate 800, 1600, or 2400 mg/day, or an identical placebo. The bone mineral density (BMD) of the lumbar spine (L2-4), femoral neck, and trochanter were assessed using dual-energy X-ray absortiometry at entry, 6 months, and 12 months. The baseline BMDs did not differ significantly between the study groups. In the lumbar spine, the mean BMD increased significantly between the baseline and 12-month visit in the clodronate groups of 1600 and 2400 mg/day, 2.6% (0.02 g/cm2, p < 0.02) and 3.0% (0.03 g/cm2, p < 0.01), respectively, but not in the placebo and clodronate 800 mg/day groups. The test for a linear trend (BMD percent change for L2-4) at 12 months was significant (p < 0.02), indicating a dose response to clodronate. The mean BMD values of the femoral neck increased significantly in the 2400 mg/day group, 4.3% (0.03 g/cm2, p < 0.0001), as well as in the trochanter region 2.8% (0.02 g/cm2, p < 0.02). Gastric irritation was the most common adverse effect noted on a clodronate dose of 2400 mg/day. We conclude that oral clodronate is effective in preventing bone loss or increasing bone mass in asthmatic patients having a long history of continuous peroral and inhaled corticosteroid administration.

Abstract
The impact of coronary heart disease (CHD) on elderly patients' functional abilities is of growing interest because of the increasing number of people that survive the disease. The aim of our study was, firstly, to describe functional abilities among elderly CHD patients and, secondly, to analyze the relationships between physical disability and the severity of chest pain or dyspnea. The third aim was to assess whether there is an independent association between physical disability and CHD. The study was carried out at the health center of the municipality of Lieto, southwestern Finland. From a population of 1196 community-dwelling persons aged > or = 64 years, 89 men and 73 women with CHD (angina pectoris and/or a past myocardial infarction) were selected along with 178 male and 146 female sex- and age-matched controls without CHD. Physical functioning was assessed by means of interviewer-based questionnaires, compared between patients and controls and described in relation to the severity of chest pain and dyspnea among patients. The associations between dependence or difficulties in mobility, ADL (activities of daily living) and IADL (instrumental activities of daily living) and CHD, age, smoking, comorbidities, drug therapy and clinical characteristics were assessed by logistic regression analyses. On items representing mobility and managing in IADL, patients reported more difficulties or dependence than controls. Among female patients, more severe chest pain was associated with poor managing in IADL and tended to be associated with poor mobility. More severe dyspnea was associated with poor mobility among both male and female patients, and with poor managing in IADL among male patients. Logistic regression analyses failed to show that CHD was associated independently with physical disability among the elderly. However, physical disability was associated with the use of cardiovascular drugs in the models among both genders, which probably indirectly indicated an association between physical disability and CHD. Several confounding factors, such as higher age, depression, cancer and the use of psychotropic drugs, contributed to the decline in functional abilities even among persons with CHD. In conclusion, elderly CHD patients have greater limitations in their functional ability than matched controls, which may depend on the severity of the disease. Especially male patients' limitations in physical abilities may be influenced by the fact that men with CHD are more likely to be depressed. Although an independent association between physical disability and CHD was not found, the associations found between physical disability and the use of cardiovascular drugs probably indicate a causal relationship between CHD and physical disability.

Abstract
BACKGROUND Growing interest is nowadays focused on the quality of life of elderly people who survive with chronic diseases. Coronary heart disease (CHD) is one of the most common diseases among the elderly and may have an unfavourable impact on the patient's emotional well-being. OBJECTIVES We aimed to describe the prevalence of depression and the occurrence of depressive symptoms among elderly CHD patients, with a special emphasis on the relations between depression and the severity of CHD, and to find out the possible association between CHD and depression. METHODS The study was carried out at the health centre of the municipality of Lieto, in south-west Finland. The study population consisted of 488 community-dwelling men and 708 women, over 64 years old, from among whom the participants with CHD (89 men and 73 women) were selected, and for whom 178 male and 146 female sex- and age-matched controls (free of CHD) were drawn from the population. CHD patients were selected on the basis of the presence of angina pectoris or a past myocardial infarction. Depressive symptoms were measured with the Zung Self-rating Depression Scale. Depression was described in relation to the severity of dyspnoea and chest pain among patients. The associations between depression and age, health, health behaviour, drugs, functional ability and social, psychosocial and environmental factors were analysed by logistic regression analyses. RESULTS The prevalence of depression was 29% among male patients and 20% among female patients. Depression was significantly more common among male CHD patients than among male controls (P = 0.011). Among women, depression was not associated with CHD. Earlier, depression had gone undiagnosed among many CHD patients and controls, especially male patients. Among male CHD patients, depression was associated with more severe dyspnoea, but no similar association was found among female CHD patients. Among men the occurrence of CHD, physical disability, widowhood or divorce, and among women previous clinical depression, physical disability and the use of angiotensin-converting enzyme (ACE) inhibitors, were associated with depression. CONCLUSION Depression is common among patients with CHD. It seems that CHD is not an independent factor in the aetiology of depression among the elderly. The association of CHD with depression among men is explained by the acute or chronic psychic stress caused by CHD. It may be that the more complicated the patient's CHD, the more probable is the presence of depression.

Abstract
The use of inhaled corticosteroids in bronchial asthma has widened, but there is a lack of data on their effect on bone collagen synthesis and degradation. This paper reports the effect of three dose levels (200, 1000 and 2000 micrograms day-1, 3 weeks each) of inhaled beclomethasone on specific characteristics of bone collagen metabolism in seven postmenopausal women with new asthma without any previous corticosteroid therapy. Serum aminoterminal (PINP) propeptide of human type I procollagen was seen, after an initial increase, to decrease significantly (from 42.2 to 35.5 micrograms l-1, P = 0.001) with the higher doses of inhaled beclomethasone, but no statistical change was found in the carboxyterminal propeptide (PICP) or type I collagen crosslinked telopeptide (ICTP). This data shows that type I collagen synthesis may be disturbed when using high-dose inhaled corticosteroids. However, further studies are needed to assess the effects of inhaled beclomethasone on the ability of the osteoblasts to form bone matrix, and on the density of bone during a longer treatment period with inhaled corticosteroids.

Abstract
In a cross-sectional epidemiological study in Lieto, Finland, 61 men and 21 women with chronic obstructive pulmonary disease (COPD) were compared with age- and sex-matched controls from the same community to analyze the associations between COPD, cognitive performance, and occurrence of dementia. The cognitive assessment was based on the Mini-Mental State Examination (MMSE), previous clinical documents, and the assessment made by the research nurse after she had interviewed and tested each subject. These three measures revealed no differences between the COPD patients and the age-matched controls, and MMSE subtest scores did not differ significantly between the patients and controls. The findings suggest that the relative contribution of COPD to the occurrence of cognitive impairment and dementia in the elderly may be none or minimal at the community level.
