Objective: Our aim was to study the associations of childhood lifestyle factors (the frequency of consumption of vegetables, fruit, fish, and meat, butter use on bread, and physical activity) with the metabolic syndrome (MetS) in adulthood.Research Design and Methods: The study cohort consisted of 2,128 individuals, 3-18 years of age at the baseline, with a follow-up time of 27 years. We used the average of lifestyle factor measurements taken in 1980, 1983, and 1986 in the analyses. Childhood dietary factors and physical activity were assessed by self-reported questionnaires, and a harmonized definition of MetS was used as the adult outcome.Results: Childhood vegetable consumption frequency was inversely associated with adult MetS (odds ratio [OR] 0.86 [95% CI 0.77-0.97], P = 0.02) in a multivariable analysis adjusted with age, sex, childhood metabolic risk factors (lipids, systolic blood pressure, insulin, BMI, and C-reactive protein), family history of type 2 diabetes and hypertension, and socioeconomic status. The association remained even after adjustment for adulthood vegetable consumption. Associations with the other childhood lifestyle factors were not found. Of the individual components of MetS, decreased frequency of childhood vegetable consumption predicted high blood pressure (0.88 [0.80-0.98], P = 0.01) and a high triglyceride value (0.88 [0.79-0.99], P = 0.03) after adjustment for the above-mentioned risk factors.Conclusions: Childhood vegetable consumption frequency is inversely associated with MetS in adulthood. Our findings suggest that a higher intake of vegetables in childhood may have a protective effect on MetS in adulthood. [ABSTRACT FROM AUTHOR]

PURPOSE: To examine the relationship of physical activity and its changes over a 9-yr follow-up to the prevalence of metabolic syndrome (MetS) in 2060 young adults (24-39 yr) enrolled in the Cardiovascular Risk in Young Finns Study. METHODS: Leisure-time physical activity (LTPA) was assessed using a self-report questionnaire completed in connection with a medical examination at two consecutive measurements in 1992 and 2001. By summing the LTPA items, a physical activity index (PAI) was formed for both measurement points according to which the participants were divided into tracking groups: persistently active, increasingly active, decreasingly active, and persistently inactive. MetS in 2001 was defined by the guidelines of the European Group for the Study of Insulin Resistance (EGIR), the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III), and the International Diabetes Federation (IDF). A continuous metabolic risk score was also calculated by summing the z-scores for the metabolic risk factors. RESULTS: There was a significant linear relationship between MetS and LTPA at baseline in men and at follow-up in both sexes according to all three definitions. Persistent physical activity during 9 yr was associated with a lower prevalence of MetS than persistent physical inactivity on all definitions (all P < 0.05). Similar results were found for increasingly active women (all P < 0.05). All of these associations remained significant after adjustment for potential confounders. In both men and women, the 9-yr change in LTPA was related to the metabolic risk score after adjustments for baseline LTPA, age, smoking, and education. CONCLUSIONS: A physically active lifestyle across the lifespan may prevent or delay the onset of metabolic syndrome in young male and female adults. [ABSTRACT FROM AUTHOR]

We investigated the associations of anger and cynicism with carotid artery intima-media thickness (IMT) and whether these associations were moderated by childhood or adulthood socioeconomic status (SES). The participants were 647 men and 893 women derived from the population-based Cardiovascular Risk in Young Finns Study. Childhood SES was measured in 1980 when the participants were aged 3-18. In 2001, adulthood SES, anger, cynicism, and IMT were measured. There were no associations between anger or cynicism and IMT in the entire population, but anger was associated with thicker IMT in participants who had experienced low SES in childhood. This association persisted after adjustment for a host of cardiovascular risk factors. It is concluded that the ill health-effects of psychological factors such as anger may be more pronounced in individuals who have been exposed to adverse socioeconomic circumstances early in life.

The article discusses a study which evaluated the influence of youth physical activity as well as demographic, behavioral, psychological, and environmental factors on adult physical activity. Data showing the results of examination of the correlates between adult physical activity and independent variables are presented. The findings suggest that high level of leadership in the subjects in age-gender groups influence adult physical activity.

As a part of the large project Cardiovascular Risk in Young Finns, the purpose of the present study was to examine how adult physical activity is influenced by early physical activity and current social and health-related factors. A total of 2411 children and adolescents aged 9, 12, 15 and 18 years were randomly selected from five university towns and their rural surroundings in 1980. They were followed up for 12 years by means of questionnaires. In 1992 they were 21, 24, 27 and 30 years old. The results showed that early physical activity and current social and health-related behaviours were significantly related to the level of adult physical activity. Multivariable analyses indicated that early physical activity, in particular, was the best predictor of adult physical activity in all groups, with the exception of the 21-year-old women. The social and health-related factors such as occupation, employment status and smoking also predicted physical activity in some age-gender groups. [ABSTRACT FROM AUTHOR]

Background: To examine if major life changes over a 4-year period among 34- to 49-year-old adults (mean = 41.8, SD = 5.0) were associated with a change in physical activity in men (37.7%) and women (62.3%)., Methods: Daily steps and aerobic steps (steps that lasted for at least 10 min without interruption at a pace of >60 steps/min) were collected from 1051 participants in 2007 and 2011. Changes in marital status, work status, and residence and the birth of a child were determined from both time points. A latent change score model was used to examine mean changes in daily total steps, aerobic steps, and nonaerobic steps (total steps minus aerobic steps)., Results: Women who had a first child in the 4-year period had a decrease in their nonaerobic steps (P = .001). Men who divorced in the 4-year period had a decrease in their nonaerobic steps (P = .020), whereas women who recoupled decreased their total steps (P = .030)., Conclusions: Counseling for parents having a first child on how to increase physical activity in their everyday life could potentially have an influence on an individual's physical activity.

Aim: The aim of this prospective four-year follow-up study was to examine how socioeconomic status (SES) and change in marital status are associated with the change in pedometer-measured physical activity (PA) in adulthood among participants in the 'Cardiovascular Risk in Young Finns Study'. Methods: Questionnaires were completed and pedometers worn at baseline in 2007 and again at follow-up in 2011 by 1051 Finnish adults (62.3% female, aged 30-45 years in 2007). A latent change score model was used to examine mean change in daily total steps, aerobic steps and non-aerobic steps during weekdays and weekend days between 2007 and 2011. Results: In women re-coupling or finding a new partner was associated with decrease in total steps ( p =0.010) and being single was associated with increase in non-aerobic steps ( p =0.047) during weekdays from 2007 to 2011 compared to women who were married. In men, divorcing was associated with decrease in non-aerobic steps ( p =0.049). Conclusions : In order to promote PA in the general population of adults, it is recommended to pay attention to people with lower SES and those who have had changes in their marital status. These factors could be taken into account when developing strategies to promote PA among the adult population.

Introduction: Physical activity (PA) has been suggested to protect against old-age cognitive deficits. However, the independent role of childhood/youth PA for adulthood cognitive performance is unknown. This study investigated the association between PA from childhood to adulthood and midlife cognitive performance., Methods: This study is a part of the Cardiovascular Risk in Young Finns Study. Since 1980, a population-based cohort of 3596 children (age, 3-18 yr) have been followed up in 3- to 9-yr intervals. PA has been queried in all study phases. Cumulative PA was determined in childhood (age, 6-12 yr), adolescence (age, 12-18 yr), young adulthood (age, 18-24 yr), and adulthood (age, 24-37 yr). Cognitive performance was assessed using computerized neuropsychological test, CANTAB® (N = 2026; age, 34-49 yr) in 2011., Results: High PA in childhood (β = 0.119; 95% confidence interval [CI], 0.055-0.182) and adolescence (β = 0.125; 95% CI, 0.063-0.188) were associated with better reaction time in midlife independent of PA in other age frames. Additionally, an independent association of high PA in young adulthood with better visual processing and sustained attention in midlife was observed among men (β = 0.101; 95% CI, 0.001-0.200). There were no associations for other cognitive domains., Conclusions: Cumulative exposure to PA from childhood to adulthood was found to be associated with better midlife reaction time. Furthermore, cumulative PA exposure in young adulthood and adulthood was associated with better visual processing and sustained attention in men. All associations were independent of participants PA level in other measured age frames. Therefore, a physically active lifestyle should be adopted already in childhood, adolescence, and young adulthood and continued into midlife to ensure the plausible benefits of PA on midlife cognitive performance.

Background and Aims: In the 1960s and 1970s, Finland, mortality due to coronary heart disease (CHD) was over 30% higher among Finns residing in the east of the country compared with those residing in the west. Today, CHD mortality remains 20% higher among eastern Finns. The higher incidence of CHD mortality among eastern Finns has largely been explained by higher risk factor levels. Using a unique longitudinal cohort, we aimed to determine if participants who resided in eastern Finland during childhood had higher CHD risk factors in adulthood and from childhood to adulthood., Methods: The study population included 2063 participants of the Cardiovascular Risk in Young Finns Study, born during the period 1962-1977, with risk factor data available from baseline (1980) when participants were aged 3-18 years, and had risk factor data collected again in adulthood (2011) when aged 34-49 years., Results: Adult CHD risk factor profile was similar for those who resided in eastern or western Finland in childhood. Over life-course from 1980 to 2011, those subjects with childhood residency in eastern Finland had, on average, higher systolic (p = 0.006) and diastolic (p = 0.0009) blood pressures, total (p = 0.01) and LDL-cholesterol (p = 0.01), triglycerides (p = 0.04), apoB (p = 0.02), and serum glucose (p < 0.0001) than those who resided in western Finland in childhood., Conclusions: Our sample of adult Finns aged 34-49 years had a similar CHD risk factor profile irrespective of whether they resided in eastern or western Finland during their childhood. However, when considering participants risk factor profiles over a 31-year period, those who resided in eastern Finland in childhood were associated with a less favorable CHD risk factor profile than those who resided in western Finland in childhood. The observed differences suggest that future CHD mortality might remain higher in eastern Finland compared with western Finland., (Copyright © 2018. Published by Elsevier B.V.)

Introduction: Physical activity (PA) is important in the prevention and treatment of impaired glucose metabolism. However, association of physical inactivity during the transition between childhood and adulthood with glucose metabolism is unknown. Therefore, we studied the association of persistent physical inactivity since childhood with glucose metabolism in adulthood., Methods: Data were drawn from the ongoing, Cardiovascular Risk in Young Finns Study with repeated follow-ups between 1980 and 2011 (baseline age, 3-18 yr; n = 3596). Impaired glucose metabolism was defined as having impaired fasting glucose (6.1-6.9 mmol·L) or type 2 diabetes in adulthood. Leisure-time PA habits were repeatedly collected with a standardized questionnaire and expressed as a PA Index. Using PA Index, four groups were formed (n = 2000): 1) persistently low PA, 2) decreasingly active, 3) increasingly active, and 4) persistently active subjects. Poisson regression model was used to examine the association between PA groups and impaired glucose metabolism., Results: The proportion of the sample with impaired glucose metabolism was 16.1% in individuals with persistently low PA, 14.5% in decreasingly active, 6.8% in increasingly active, and 11.1% in persistently active. Compared with individuals with persistently low PA, age and sex-adjusted risk for impaired glucose metabolism were lower in those who increased PA (relative risk [RR], 0.47; 95% confidence interval [CI], 0.29-0.76) and in those who were persistently active (RR, 0.70; 95% CI, 0.51-0.97), but similar in those who decreased PA (RR, 0.93; 95% CI, 0.66-1.36)., Conclusions: Persistently physically inactive lifestyle from youth to adulthood is associated with increased risk of impaired glucose metabolism in adulthood. Importantly, a moderate increase in PA lowered the risk. The results highlight the importance of avoiding physically inactive lifestyle at all stages of life.

Aims: Over the study years, there was a significant increase in body mass index (BMI) and waist-to-height ratio (WtHR) in middle aged Finnish adults. Methods: Data were obtained from 1033 Finnish adults from the Cardiovascular Risk in Young Finns Study in 2007 and 2011. Cohort study participants wore an Omron Walking Style One (HJ-152R-E) pedometer for five days and were grouped into those who increased, maintained and decreased their steps between 2007 and 2011. Paired samples t -test was used to compare body mass index (BMI) and waist-to-height ratio (WtHR) change values between the change groups in study years. Results : Among study population BMI and WtHR increase between study years was statistically significant ( p < 0.001). Only those, who increased their total steps for at least 2000 steps, maintained their BMI in the same level, while people who decreased or maintained their total steps in the same level, BMI and WtHR increased during four years follow-up. Conclusions: This data suggests that increasing steps in middle age is associated with maintaining BMI at the same level., Competing Interests: The authors declare no conflict of interest.

Purpose: Fatty liver is an expanding health concern associated with metabolic disturbances and increased risk of cardiovascular disease. Experimental studies in animals have shown associations between fatty liver and cardiorespiratory fitness but limited data exist in humans. The aim of this study was to analyze the links between cardiorespiratory fitness and fatty liver in a population-based sample of adults., Methods: Participants were 463 adults (48% men) from the Cardiovascular Risk in Young Finns Study. Cardiorespiratory fitness was measured with a cycle ergometer exercise test as peak oxygen uptake (V˙O2peak [mL·kg·min]) in 2008 to 2009. Hepatic ultrasonographic imaging was performed in 2011 to determine fatty liver., Results: Cardiorespiratory fitness was associated with lower risk of fatty liver (1 mL·kg·min increase in V˙O2peak: risk ratio, 0.90; 95% confidence interval, 0.88-0.93, P < 0.0001; adjusted for age and sex). This association remained significant after further adjustments with physical activity, adiposity, smoking, alcohol consumption, serum lipids, insulin, glucose, and C-reactive protein. Participants who were obese (waist circumference, >80 cm in women and >94 cm in men) but fit (V˙O2peak in the upper age- and sex-specific median) had lower prevalence of fatty liver than participants who were obese and unfit (below median), (11.7% vs 34.8%, P = 0.0003)., Conclusions: In a population-based sample of adults, cardiorespiratory fitness is strongly, inversely and independently related with the risk of fatty liver. Importantly, the association is evident also among obese.

Purpose: We examined associations between childhood temperamental activity, physical activity (PA), and television (TV) viewing over a 30-year period., Method: The participants (1220 boys and 1237 girls) were aged 3, 6, 9, and 12 years in 1980 and were followed until 2011. Temperamental activity was evaluated by participants' mothers at baseline. The PA was assessed based on maternal ratings of the child from ages 3 to 6 and via self-report age from the age of 9 across all measurements. TV viewing was assessed using self-reports taken from 2001 to 2011. The associations between temperamental activity and the level and change of PA and TV viewing were determined using linear growth modeling stratified by gender and age group., Results: High temperamental activity assessed from ages 9 to 12 was associated with high levels of childhood PA in both genders, but with a steeper decline in PA levels during the first 9 years of follow-up in boys. High temperamental activity assessed from ages 3 to 6 was associated with the decline of PA from childhood to youth in girls. High childhood temperamental activity was associated with decreased levels of PA in adulthood in men, but not in women. The associations between childhood temperamental activity and TV viewing during adulthood seemed to be positive but not consistently significant in all age and gender groups., Conclusion: High temperamental activity may contribute to the development of a physically inactive lifestyle. More evidence is needed with regard to gender differences among participants in similar study settings.

Schizophrenia spectrum disorders are associated with high morbidity and mortality in somatic diseases. The risk factors of this excess mortality include, e.g., obesity, dietary factors, and physical inactivity, especially after the onset of psychosis, but there are limited early developmental data on these factors in individuals who later develop psychosis. A population-based cohort study "Cardiovascular Risk of Young Finns" started in 1980 with 3596 children and adolescents from six different age groups (3, 6, 9, 12, 15, and 18 years). Cardiovascular health parameters, including questionnaire of physical activity before first hospitalization (≤18 years), were studied in 1980, 1983, and 1986. All psychiatric diagnoses of the participants were derived from the Finnish Hospital Discharge Register up to the year 2012. We identified diagnostic groups of non-affective psychosis ( n  = 68, including a schizophrenia subgroup, n  = 41), personality disorders ( n  = 43), affective disorders ( n  = 111), and substance-related disorders ( n  = 49), based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Groups were compared with controls with no psychiatric diagnoses ( n  = 3325). Sex, age, body mass index, birth weight, non-preterm birth, and mother's mental disorders were included in the statistical model. Low physical activity in childhood and adolescence (9-18 years) independently predicted later development of non-affective psychosis. Lower physical activity index (relative risk 1.26 [1.1-1.5]), lower level of common activity during leisure time (relative risk 1.71 [1.2-2.5]), and non-participation in sports competitions (relative risk 2.58 [1.3-5.3]) were associated with a higher risk for later non-affective psychosis (expressed as increase in relative risk per physical activity unit). The findings were even stronger for schizophrenia, but no such link was observed for other diagnoses. The cause of low physical activity in premorbid/prodromal phase is likely to be multifactorial, including deviant motor and cognitive development. The results provide a rationale for including exercise and physical activity interventions as a part of psychosis prevention programs.

Purpose: The aim of this study was to investigate the tracking of television viewing (TV) time as an indicator of sedentary behavior among adults for a period of 25 yr., Methods: A random sample of 1601 subjects (740 men) age 18, 21, and 24 yr participated in the Cardiovascular Risk in Young Finns Study in 1986. TV time during leisure time was measured with a single self-report question at baseline and in 2001, 2007, and 2011. Tracking of TV time was analyzed using Spearman rank correlations and simplex models. Level and change of TV time were examined using linear growth modeling., Results: The 4- and 6-yr integrated TV time stability coefficients, adjusted for measurement errors, were ≥0.60 in adulthood and quite similar for both men and women. The stability coefficients tended to decline as the time interval increased. The stability of the indirect estimation of TV time for a 25-yr period was moderately or highly significant for both genders in most age groups. Younger age, but not gender, was found to be associated with a higher initial level of TV time. Male gender and older age were found to be significantly associated with the slope of TV time., Conclusion: The stability of TV time is predominantly moderate to high during adulthood and varies somewhat by age and gender.

Background & Aims: Fatty liver is a potentially preventable cause of serious liver diseases. This longitudinal study aimed to identify childhood risk factors of fatty liver in adulthood in a population-based group of Finnish adults., Methods: Study cohort included 2,042 individuals from the Cardiovascular Risk in Young Finns Study aged 3-18years at baseline in 1980. During the latest follow-up in 2011, the liver was scanned by ultrasound. In addition to physical and environmental factors related to fatty liver, we examined whether the genetic risk posed by a single nucleotide polymorphism in the patatin-like phospholipase domain-containing protein 3 gene (PNPLA3) (rs738409) strengthens prediction of adult fatty liver., Results: Independent childhood predictors of adult fatty liver were small for gestational age, (odds ratio=1.71, 95% confidence interval=1.07-2.72), variant in PNPLA3 (1.63, 1.29-2.07 per one risk allele), variant in the transmembrane 6 superfamily 2 gene (TM6SF2) (1.57, 1.08-2.30), BMI (1.30, 1.07-1.59 per standard deviation) and insulin (1.25, 1.05-1.49 per standard deviation). Childhood blood pressure, physical activity, C-reactive protein, smoking, serum lipid levels or parental lifestyle factors did not predict fatty liver. Risk assessment based on childhood age, sex, BMI, insulin levels, birth weight, TM6SF2 and PNPLA3 was superior in predicting fatty liver compared with the approach using only age, sex, BMI and insulin levels (C statistics, 0.725 vs. 0.749; p=0.002)., Conclusions: Childhood risk factors on the development of fatty liver were small for gestational age, high insulin and high BMI. Prediction of adult fatty liver was enhanced by taking into account genetic variants in PNPLA3 and TM6SF2 genes., Lay Summary: The increase in pediatric obesity emphasizes the importance of identification of children and adolescents at high risk of fatty liver in adulthood. We used data from the longitudinal Cardiovascular Risk in Young Finns Study to examine the associations of childhood (3-18years) risk variables with fatty liver assessed in adulthood at the age of 34-49years. The findings suggest that a multifactorial approach with both lifestyle and genetic factors included would improve early identification of children with a high risk of adult fatty liver., (Copyright © 2016 European Association for the Study of the Liver.
