RESUMEN
BACKGROUND: Inflammation has been suggested to be one, possibly treatable, cause of cognitive decline and dementia. The purpose of the present article was to investigate whether the herpes simplex virus 1 (HSV-1) or Toxoplasma gondii (T. gondii) infections are related to cognitive decline or dementia. METHOD: The Health 2000 survey, conducted 2000-2001, is a population-representative sample of people over 30â¯years old that involved 7112 participants. The sample was followed up in the year 2011, in the Health 2011 study. At both time points, cognitive performance was assessed with two tests from the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) assessing verbal fluency and verbal learning. In addition, the abbreviated Mini-Mental State Examination was administered to people aged over 55. In addition, tests assessing reaction and movement time were performed at baseline. Dementia diagnoses from nationwide health care registers were followed up until the end of year 2013. The presence of HSV-1 and T. gondii immunoglobulin G (IgG) was determined by solid-phase immunoassay at baseline. RESULTS: HSV-1 or T. gondii seropositivity, or IgG antibody levels, were not associated with cognitive decline when investigated as infectionâ¯×â¯time interactions. In addition, the infections were not associated with the risk of dementia. CONCLUSIONS: In a large sample of participants that is representative of the whole country and with a long follow-up, the results suggest that latent HSV-1 or T. gondii infections are not related to either decline in cognitive performance or dementia risk.

BACKGROUND: Empirical evidence on whether patients' mental health and functioning will be more improved after long-term than short-term therapy is scarce. We addressed this question in a clinical trial with a long follow-up. METHOD: In the Helsinki Psychotherapy Study, 326 out-patients with mood or anxiety disorder were randomly assigned to long-term psychodynamic psychotherapy (LPP), short-term psychodynamic psychotherapy (SPP) or solution-focused therapy (SFT) and were followed for 10 years. The outcome measures were psychiatric symptoms, work ability, personality and social functioning, need for treatment, and remission. RESULTS: At the end of the follow-up, altogether 74% of the patients were free from clinically elevated psychiatric symptoms. Compared with SPP, LPP showed greater reductions in symptoms, greater improvement in work ability and higher remission rates. A similar difference in symptoms and work ability was observed in comparison with SFT after adjustment for violations of treatment standards. No notable differences in effectiveness between SFT and SPP were observed. The prevalence of auxiliary treatment was relatively high, 47% in SFT, 58% in SPP and 33% in LPP, and, accordingly, the remission rates for general symptoms were 55, 45 and 62%, respectively. CONCLUSIONS: After 10 years of follow-up, the benefits of LPP in comparison with the short-term therapies are rather small, though significant in symptoms and work ability, possibly due to more frequent use of auxiliary therapy in the short-term therapy groups. Further studies should focus on the choice of optimal length of therapy and the selection of factors predicting outcome of short- v. long-term therapy.

BACKGROUND: Many ethnic minority populations have poorer health than the general population. However, there is limited knowledge on the possible ethnic gap in physical mobility. We aim to examine the prevalence of mobility limitations in working-age Russian, Somali and Kurdish origin migrants in comparison to the general population in Finland. We also determine whether the association between ethnic group and mobility limitation remains after taking into account socio-economic and health-related factors. METHODS: We used data from the Finnish Migrant Health and Wellbeing Study (Maamu) and the Finnish Health 2011 Survey. The participants comprised 1880 persons aged 29-64 years. The age-adjusted prevalence of difficulties in various mobility tasks was calculated using predictive margins. Logistic regression analysis was used to examine the association between socio-economic, health- and migration-related factors and mobility limitation (self-reported difficulty in walking 500 m or stair climbing). The association between ethnic group and mobility limitation was calculated using logistic regression analysis. RESULTS: Mobility limitations were much more prevalent among Somali origin women (46 %) and Kurdish origin men (32 %) and women (57 %) compared to men and women in the general Finnish population (5-12 %). In Russian origin men and women, the prevalence of mobility limitation (7-17 %) was similar to the general Finnish population. Socio-economic and health-related factors, but not migration-related factors (time lived in Finland and language proficiency in Finnish or Swedish), were found to be associated with mobility limitation in the studied populations. Somali and Kurdish origin migrants were found to have increased odds for mobility limitation compared to the general Finnish population, even after adjusting for socio-economic and health-related factors (Somalis odds ratio [OR] 3.61; 95 % confidence interval [CI] 2.07-6.29, Kurds OR 7.40; 95 % CI 4.65-11.77). CONCLUSIONS: This study demonstrates a functional disadvantage in Somali and Kurdish origin populations compared to the general Finnish population, even after adjusting for socio-economic and health-related factors. The high prevalence of mobility limitation among Somali origin women and Kurdish origin men and women in Finland demonstrates an acute need to promote the health and functioning of these populations.

The population attributable fraction (PAF) is a useful measure for describing the expected change in an outcome if its risk factors are modified. Cohort studies allow researchers to assess the predictive value of the risk factor modification on the incidence of the outcome during a certain follow-up. Estimation of PAF for both mortality and morbidity in cohort studies with censored survival data has been developed in the recent years. So far, however, censoring due to death in the estimation of PAF for morbidity has been ignored, resulting in estimation of a quantity which is not relevant in practice as some people are likely to die during the follow-up. The risk factors related to the disease incidence may also be related to mortality, and modification of these risk factors is likely to delay the occurrence of both events. Thus, censoring due to death and the impact of risk factor modification must be considered when estimating PAF for disease incidence. We consider both and introduce two measures of disease burden: PAF for the incidence of disease during lifetime and PAF for the prevalence of disease in the population at a certain time. We demonstrate how consideration of censoring due to death changes the estimated PAF for disease incidence and its confidence interval. This underlines the importance of choosing a correct PAF measure depending on the outcome of interest and the risk factors of interest to obtain accurate and interpretable results.

Increased levels of circulating cell-free DNA (cf-DNA) are associated with and predict poor health outcomes. However, its predictive ability for mortality in population-based samples remains understudied. We analysed the capability of cf-DNA to predict all-cause mortality and assessed whether it adds predictive value on top of the other risk factors in the Health 2000 survey (n = 1,257, 46-76 years of age, 15-years-follow-up, 18% deceased). When analysed in a multivariate model with the other factors that independently predicted mortality in the sample (age, gender, self-rated health, smoking and plasma levels of glucose and adiponectin), increases in cf-DNA levels were associated with increased risk of mortality (hazard ratio [HR] for 0.1 µg increase in cf-DNA: 1.017, 95% confidence interval [CI] 1.008-1.026, p = 0.0003). Inclusion of cf-DNA in the model improved the model fit and discrimination. Stratifying the analysis by cardiovascular disease (CVD) status indicated that cf-DNA predicted mortality equally well in individuals with (HR 1.018, 95% CI 1.008-1.026, p = 0.002) and without (HR 1.018, 95% CI 1.001-1.035, p = 0.033) CVD. In conclusion, our study indicates that cf-DNA level predicts mortality in middle-aged and older individuals, also among those with established CVD, and adds significant value to mortality prediction. Our results thus underscore the role of cf-DNA as a viable marker of health.

Our aim in this study was to determine whether there is an association between cynical hostility and clinically determined poor oral health, and whether this association is confounded by socioeconomic position and mediated by health behavior. The sample consisted of 4,207 dentate Finns, 30-64 yr of age. Oral health was measured in terms of numbers of missing teeth, of decayed teeth, and of teeth with periodontal pockets (> or = 4 mm). Cynical hostility was measured using the cynical distrust self-administered questionnaire. The subjects with the highest level of cynical hostility had fewer teeth, and a greater number of decayed teeth as well as teeth with deepened periodontal pockets compared to subjects with the lowest level of cynical hostility. The associations between cynical hostility and number of missing and decayed teeth were clearly confounded by level of education. Poor oral health behavior was shown to be a possible mediator between cynical hostility and number of decayed teeth, but not of missing teeth or teeth with deepened periodontal pockets. General health-related behavior did not serve as a possible mediator in any of the associations. In conclusion, cynical hostility can be considered as a risk marker for poor oral health. Interventions aimed to improve oral health should focus on psychosocial factors and on less-educated subjects.

OBJECTIVE: Our aim was to investigate the mutual relationship between oral and general health behaviours and oral and general subjective health among adults, and to explore whether sense of coherence (SOC) could be a common health-promoting correlate for them. PARTICIPANTS: The present study included data for 4096 30- to 64-year-old dentate adults (2177 females and 1919 males). BASIC RESEARCH DESIGN: In the nationally representative, cross-sectional sample including 8028 persons aged 30, or more, 88% were surveyed. The questionnaire and home interview included information about socio-economic and demographic factors, behavioural and psycho-social variables. Chi-square test and logistic regression models were used in the data analysis. MAIN OUTCOME MEASURES: The main outcome measures were oral health behaviours (regular dental attendance, twice a day tooth-brushing frequency), general health behaviours (non-smoking habits, physical activity at least twice a week), subjective oral and general health and the SOC (12-item) scale. RESULTS: Among females, positive health behaviours tended to occur together significantly more often than among males. Thus, 83% of females with more than once a week physical exercise frequency, and 79% of the non-smoking females, brushed their teeth at least twice a day, while the corresponding figures for the males were merely 55% and 50%. A strong SOC was associated with uniformly positive health behaviours and subjective oral and general health. CONCLUSIONS: Our results suggest that a strong SOC has a universal positive association with several health behaviours and subjective health measures, also concerning oral health. Thus, the role of psycho-social factors should not be underestimated in health promotion.

BACKGROUND: Metabolic syndrome (MetS) is associated with a substantially increased risk for cardiovascular disease and diabetes. We examined the contribution of length of residence, socioeconomic position and lifestyle-related factors to the differences in the prevalence of MetS among migrants compared with Finns. METHODS: Cross-sectional data from randomly sampled 30-64year-old health examination participants (318 Russian, 212 Somali, and 321 Kurdish origin migrants) of the Migrant Health and Wellbeing Survey (2010-2012) were used. Health 2011 Survey participants (n=786) were the reference group. RESULTS: Compared with Finns, prevalence of MetS was significantly higher among all migrants except for Somali men. Among men, age-adjusted prevalence ratio (PR) of MetS compared with Finns was 1.71, 95% confidence interval (CI) 1.19-2.46 for Russians, PR 0.95 (95% CI 0.54-1.67) for Somali, and PR 2.10 (95% CI 1.51-2.93) for Kurds. Among women, respective PRs were 1.45 (95% CI 1.08-1.97) for Russians, PR 2.34 (95% CI 1.75-3.14) for Somali and PR 2.22 (95% CI 1.67-2.97) for Kurds. Adjustment for sociodemographic and lifestyle-related factors attenuated the differences in MetS among women but not men. CONCLUSIONS: Further studies should aim at identifying factors related to elevated risk for MetS among Russian and Kurdish men. Interventions aiming at improving lifestyle-related factors are needed for reducing inequalities in the prevalence of MetS among migrant women. Effectiveness of interventions focusing on reducing overweight and obesity among Somali and Kurdish women should be evaluated.

AIM: The study aimed to examine the role of the metabolic syndrome (MetS) as a predictor of incident cardiovascular disease (CVD) events and incident diabetes, and to compare the various definitions of MetS. METHODS: The population-based Health 2000 Study included 6105 individuals, aged 30-79 years, followed-up for 7 years. CVD during follow-up was defined as coronary death, acute myocardial infarction, coronary revascularization or stroke. MetS was defined according to the International Diabetes Federation (IDF), the 2005 National Cholesterol Education Program-Adult Treatment Panel III (ATP III), the World Health Organization (WHO) and the new Harmonization definitions. The Bayesian information criterion (BIC) was used to compare different Cox proportional-hazards regression models. RESULTS: The highest prevalence estimates of MetS at baseline were observed with the Harmonization definition: 47.8% in men and 40.7% in women. During the follow-up, 238 cases of incident CVD and 172 cases of incident diabetes were observed. All definitions of MetS were significant predictors for incident CVD and diabetes. BIC suggested that the new Harmonization definition of MetS as one entity was a better predictor of the CVD endpoint than the sum of its components, but not for diabetes. Also, the Harmonization definition of MetS was a better predictor of CVD than the Framingham equation in women, but not in men. CONCLUSION: Irrespective of definition, MetS is a significant predictor of incident CVD events and incident diabetes. Also, the new Harmonization definition may be a better predictor of incident CVD than the sum of its components.

We investigated changes in the prevalence of obesity among Finnish adults (aged > or = 30 years) during a 20-year period. Data were derived from two cross-sectional nationally representative surveys (n = 13 844) in 1978-1980 and 2000-2001. Weight and height were measured using a standardized protocol. Obesity was defined as body mass index (BMI) > or = 30 kg m(-2). Cut-offs of BMI > or = 35 kg m(-2) and BMI > or = 40 kg m(-2) were also used. A 20-year difference in the prevalence of obesity was from 11.3% to 20.7% in men and from 17.9% to 24.1% in women. In 1978-1980, 1.1% of men and 3.8% of women had a BMI at least 35 kg m(-2). The corresponding prevalence was 3.9% in men and 6.8% in women 20 years later. The educational gradient in obesity diminished in 20 years because of the most prominent increase among highly educated men. Yet, 25% of men and 28% of women with low education are obese. Obesity increased in all age and educational groups over the 20-year period. It was highest among women and individuals with the lowest education, but the increase was most striking among well-educated men. A comprehensive public health strategy targeting the whole population and especially those with low education is urgently needed to halt the obesity epidemic.

The tetanus and diphtheria vaccination programme in Finland has been running for 50 years. After primary doses, tetanus boosters have been offered to men in military service and decennial boosters recommended for all through the adult life. For 30 years a diphtheria booster was only offered to men in the military service. Not until 1989 diphtheria-tetanus (dT) and diphtheria (d) booster vaccines for adolescence and adults were introduced. In this study serum samples of 990 subjects from 30 years of age, participating in a population survey in 2000-2001, were used to assess the tetanus and diphtheria antitoxin concentrations. More than 70% of the adults up to 50 years of age were fully protected (antitoxin concentrations >0.1 IU mL) against tetanus and diphtheria. Of these adults more that 76% had antitoxin concentrations >1 IU/mL against tetanus, indicating long-term protection but also an increased risk for hyperimmunisation. A comparison of this study and two immunogenicity studies conducted in Finland in 1987-1988 and 1995-1996 shows the impact of an active decennial dT adult booster programme in a country with a high primary tetanus and diphtheria vaccination coverage in infants since the 1950s. Recommendations for limited decennial boosters by increase the time interval between dT boosters up to 20 years as suggested by this study and also studies performed, e.g., in Denmark and Portugal should be considered. Finnish adults born before 1930 should, however, still be vaccinated with decennial boosters, especially against tetanus.

BACKGROUND: The effect of mental disorders may be particularly detrimental in early adulthood, and information on mental disorders and their correlates in this age group is important. METHOD: A questionnaire focusing on mental health was sent to a nationally representative two-stage cluster sample of 1863 Finns aged 19 to 34 years. Based on a mental health screen, all screen-positives and a random sample of screen-negatives were asked to participate in a mental health assessment, consisting of the Structured Clinical Interview for DSM-IV (SCID-I) interview and neuropsychological assessment. We also obtained case-notes from all lifetime mental health treatments. This paper presents prevalences, sociodemographic associations and treatment contacts for current and lifetime mental disorders. RESULTS: Forty percent of these young Finnish adults had at least one lifetime DSM-IV Axis I disorder, and 15% had a current disorder. The most common lifetime disorders were depressive disorders (17.7%) followed by substance abuse or dependence (14.2%) and anxiety disorders (12.6%). Of persons with any lifetime Axis I disorder, 59.2% had more than one disorder. Lower education and unemployment were strongly associated with current and lifetime disorders, particularly involving substance use. Although 58.3% of persons with a current Axis I disorder had received treatment at some point, only 24.2% had current treatment contact. However, 77.1% of persons with a current Axis I disorder who felt in need of treatment for mental health problems had current treatment contact. CONCLUSIONS: Mental disorders in young adulthood are common and often co-morbid, and they may be particularly harmful for education and employment in this age group.

BACKGROUND: Insufficient evidence exists for a viable choice between long- and short-term psychotherapies in the treatment of psychiatric disorders. The present trial compares the effectiveness of one long-term therapy and two short-term therapies in the treatment of mood and anxiety disorders. METHOD: In the Helsinki Psychotherapy Study, 326 out-patients with mood (84.7%) or anxiety disorder (43.6%) were randomly assigned to three treatment groups (long-term psychodynamic psychotherapy, short-term psychodynamic psychotherapy, and solution-focused therapy) and were followed up for 3 years from start of treatment. Primary outcome measures were depressive symptoms measured by self-report Beck Depression Inventory (BDI) and observer-rated Hamilton Depression Rating Scale (HAMD), and anxiety symptoms measured by self-report Symptom Check List Anxiety Scale (SCL-90-Anx) and observer-rated Hamilton Anxiety Rating Scale (HAMA). RESULTS: A statistically significant reduction of symptoms was noted for BDI (51%), HAMD (36%), SCL-90-Anx (41%) and HAMA (38%) during the 3-year follow-up. Short-term psychodynamic psychotherapy was more effective than long-term psychodynamic psychotherapy during the first year, showing 15-27% lower scores for the four outcome measures. During the second year of follow-up no significant differences were found between the short-term and long-term therapies, and after 3 years of follow-up long-term psychodynamic psychotherapy was more effective with 14-37% lower scores for the outcome variables. No statistically significant differences were found in the effectiveness of the short-term therapies. CONCLUSIONS: Short-term therapies produce benefits more quickly than long-term psychodynamic psychotherapy but in the long run long-term psychodynamic psychotherapy is superior to short-term therapies. However, more research is needed to determine which patients should be given long-term psychotherapy for the treatment of mood or anxiety disorders.

Virtually no comparisons of different psychotherapies with long follow-up times have been carried out until now. The Helsinki Psychotherapy Study is a randomized clinical trial, where patients were monitored for 12 months after the onset of study treatments, of which each lasted approximately 6 months. The patients' psychiatric status was measured at five pre-determined time points during the follow-up period. In general, the analyses of trials are complicated in cases where compliance with the given treatment is incomplete or the drop-out from the follow-up is non-ignorable. In the present study, the quality of the treatment deviated from the protocol for some patients and some patients took auxiliary treatments which had similar effects to the study treatment during the study treatment or follow-up period. This might have resulted in standard intention-to-treat analyses providing excessively conservative or liberal conclusions. Non-compliance may have been non-ignorable in some cases, so subject-specific latent factors may have influenced the outcome both directly and indirectly via compliance behaviour. The most and least healthy patients are the most likely to dropout from the follow-up a priori, so the missing data process is informative. The missing data can partly be augmented with surrogate information collected during interviews with patients who dropped out. A Bayesian hierarchical as-treated model, which uses random-effects-based selection models to account for non-ignorable missing data and non-compliance, was compared with different mixed effects models.
