Changes and Differentials in the Prevalence of Activity Limitations among Finns Aged 65-74: Comparison of the Mini-Finland Health Examination Survey (1978-80) and the FINRISK-97 Senior Survey (1997)

This study analyses time trends in the prevalence of activity limitations andconsequent need for help according to gender, education and marital status amongFinns aged 65-74 years. The study is based on the Mini-Finland Health ExaminationStudy carried out in 1978-80 and the FINRISK-97 Senior Survey collected in 1997.During the past 20 years, functional capacity of the elderly at ages 65 to 74 hasimproved markedly. Women, more often than men, have limitations in severalactivities, but the reverse is true in some activities. Persons with higher than basiceducation have less activity limitations than others. Married or cohabiting men reportfewer difficulties in several activities than other men, but among women differencesaccording to marital status are small. A continuation of the observed decline infunctional limitations would significantly attenuate the increasing trend in the burdenof disability that is to be expected because of the ageing of the population

The Articulatory description of Finnish vowels using ultrasound

Speech has mostly been studied using measurements of speech sound acoustics. Frequencies of speech are an indirect measure of articulatory movements, and the description of articulatory has mostly been based ontactile and visual feedback of tongue and lips. The aim of the present study was to describe the articulatory system of Finnish vowels using ultrasound. Subjects’ speech data was collected during a production task in which subject read aloud pseudowords created according to Finnish phonotactic rules. Articulatory movements of the target vowels in words were analysed using Articulatory Assistant Advanced software. Vowel articulatory system was consistent and there was no great within-subject variation. Anatomical differences cause between-subject variation, but despite that, the vowel articulation form a system in which the articulatory movements of different vowels are in same relation with each other. In addition, we noticed that rounding the lips is not the only articulatory movement differentiating rounded and unrounded front vowels in Finnish.</p

Experienced Poor Lighting Contributes to the Seasonal Fluctuations in Weight and Appetite That Relate to the Metabolic Syndrome

We tested which environmental, social, lifestyle, and health related factors of the individual contribute to the seasonal variations in mood and behavior and whether these influence the risks of the metabolic syndrome and major depressive disorder, both conditions having a high prevalence in industrialized populations. 5480 individuals, representative of the general population aged 30 and over in Finland, were assessed for metabolic syndrome using the ATP-III criteria, gave a self-report of seasonal variations in mood and behavior, and were interviewed for mood, anxiety, and alcohol use disorders using the DSM-IV criteria. The seasonal variations in mood and behavior have a metabolic factor composed of weight and appetite, and greater loadings on this factor increased the risk of metabolic syndrome (odds ratio of 1.18, 95% confidence interval of 1.10 to 1.26). Self-reports of lighting experienced as poor at home contributed to scores on the metabolic factor (t = 4.20, P < .0001). Lighting conditions and their dynamics may serve as a measure for intervention in order to influence the seasonal metabolic signals and in the end to prevent the metabolic syndrome

NPAS2 and PER2 are linked to risk factors of the metabolic syndrome

<p>Abstract</p> <p>Background</p> <p>Mammalian circadian clocks control multiple physiological events. The principal circadian clock generates seasonal variations in behavior as well. Seasonality elevates the risk for metabolic syndrome, and evidence suggests that disruption of the clockwork can lead to alterations in metabolism. Our aim was to analyze whether circadian clock polymorphisms contribute to seasonal variations in behavior and to the metabolic syndrome.</p> <p>Methods</p> <p>We genotyped 39 single-nucleotide polymorphisms (SNP) from 19 genes which were either canonical circadian clock genes or genes related to the circadian clockwork from 517 individuals drawn from a nationwide population-based sample. Associations between these SNPs and seasonality, metabolic syndrome and its risk factors were analyzed using regression analysis. The p-values were corrected for multiple testing.</p> <p>Results</p> <p>Our findings link circadian gene variants to the risk factors of the metabolic syndrome, since <it>Npas2 </it>was associated with hypertension (P-value corrected for multiple testing = 0.0024) and <it>Per2 </it>was associated with high fasting blood glucose (P-value corrected for multiple testing = 0.049).</p> <p>Conclusion</p> <p>Our findings support the view that relevant relationships between circadian clocks and the metabolic syndrome in humans exist.</p

Equity in the use of antithrombotic drugs, beta-blockers and statins among Finnish coronary patients

Background Earlier studies have mainly reported the use of antithrombotic drugs, beta-blockers and statins among hospital patient populations or MI patients. This study aimed to describe the use of these drugs among middle-aged Finnish coronary patients and to identify patient groups in risk of being prescribed inadequate medication for secondary prevention of coronary heart disease. Methods One-year follow-up survey data from a random sample of a cohort of coronary patients were used along with register data linked to the survey. The response rate was 54% (n = 2650). The main outcome measures were use of antithrombotic drugs, beta-blockers and statins and the data were analysed using logistic regression analysis. Results Among men and women, respectively, 82% and 81% used beta-blockers, 95% and 89% used antithrombotic drugs, and 62% and 59% used statins. Younger men and men from higher socioeconomic groups were more likely to use statins, even after controlling for disease severity and comorbidity. In women, the age trend was reversed and no socioeconomic differences were found. Drug use increased with increased disease severity, but diabetes had only a slight effect. Conclusion The use of antithrombotic drugs and beta-blockers among Finnish coronary patients seemed to be rather appropriate and, to some extent, prescription practices of preventive medication varied according to patients' risk of coronary events. However, statin use was remarkably low among men with low socio-economic status, and there is need to improve preventive drug treatment among diabetic coronary patients.BioMed Central Open acces

Cost-effectiveness analysis of guidelines for antihypertensive care in Finland

<p>Abstract</p> <p>Background</p> <p>Hypertension is one of the major causes of disease burden affecting the Finnish population. Over the last decade, evidence-based care has emerged to complement other approaches to antihypertensive care, often without health economic assessment of its costs and effects. This study looks at the extent to which changes proposed by the 2002 Finnish evidence-based Current Care Guidelines concerning the prevention, diagnosis, and treatment of hypertension (the ACCG scenario) can be considered cost-effective when compared to modelled prior clinical practice (the PCP scenario).</p> <p>Methods</p> <p>A decision analytic model compares the ACCG and PCP scenarios using information synthesised from a set of national registers covering prescription drug reimbursements, morbidity, and mortality with data from two national surveys concerning health and functional capacity. Statistical methods are used to estimate model parameters from Finnish data. We model the potential impact of the different treatment strategies under the ACCG and PCP scenarios, such as lifestyle counselling and drug therapy, for subgroups stratified by age, gender, and blood pressure. The model provides estimates of the differences in major health-related outcomes in the form of life-years and costs as calculated from a 'public health care system' perspective. Cost-effectiveness analysis results are presented for subgroups and for the target population as a whole.</p> <p>Results</p> <p>The impact of the use of the ACCG scenario in subgroups (aged 40–80) without concomitant cardiovascular and related diseases is mainly positive. Generally, costs and life-years decrease in unison in the lowest blood pressure group, while in the highest blood pressure group costs and life-years increase together and in the other groups the ACCG scenario is less expensive and produces more life-years. When the costs and effects for subgroups are combined using standard decision analytic aggregation methods, the ACCG scenario is cost-saving and more effective.</p> <p>Conclusion</p> <p>The ACCG scenario is likely to reduce costs and increase life-years compared to the PCP scenario in many subgroups. If the estimated trade-offs between the subgroups in terms of outcomes and costs are acceptable to decision-makers, then widespread implementation of the ACCG scenario is expected to reduce overall costs and be accompanied by positive outcomes overall.</p
