Motor Competence and Health-related Fitness of School-Age Children: A Two-Year Latent Transition Analysis
2021
PURPOSE The aims of this study were twofold: 1) to identify latent physical performance profiles of motor competence (MC) and cardiorespiratory (CF) and muscular fitness (MF) among school-age children and 2) explore transition probabilities in physical performance profiles over a 2-yr period. METHODS The present sample comprised 1148 (583 girls, 565 boys) elementary school students (baseline Mage = 11.27 ± 0.32), and data were collected annually (equal intervals) over a period of 2 yr which resulted in a total of three measurements. The measures used were the throwing-catching combination test, 5-leaps and two-legged jumps from side-to-side test (MC), 20-meter shuttle run test (CF), and cur…
Gendered pathways in school burnout among adolescents
2011
The aim of this study is to examine differences in student burnout by gender, time status with two time points before and after an educational transition, and educational track (academic vs. vocational). The definition of burnout is based on three components: exhaustion due to school demands, a disengaged and cynical attitude toward school, and feelings of inadequacy as a student (Salmela-Aro, Kiuru, Leskinen, & Nurmi, 2009). A total of 770 Finnish adolescents (M age = 16) were examined at the beginning of their last year in comprehensive school, and three times annually during their secondary education both on academic and vocational tracks. Among boys on the academic track, overall school…
Self-rated health and self-assessed change in health in elderly men and women — A five-year longitudinal study
1998
The purpose of the present investigation was two fold: (1) to examine how men and women self-rate their health as they age from 75 to 80 yr and how they assess the change in their health over the five year period; and (2) to ascertain how self-assessed change in health over the follow-up period corresponded to the difference in self-ratings of health between the assessments performed at baseline and at follow-up. The study was part of the Evergreen-project with the study group comprising all inhabitants born in 1914 (N = 388) living in Jyväskylä, central Finland. At baseline, 93.4%, and at follow-up, 93.3%, of those who were eligible participated in the interview. Self-rated health, when as…
Bed-side inferior vena cava diameter and mean arterial pressure predict long-term mortality in hospitalized patients with heart failure: 36 months of…
2015
In discharged patients with heart failure (HF), diverse conditions can intervene to worsen outcome. We would investigate whether such factors present on hospital admission can affect long-term mortality in subjects hospitalized for acute HF.One hundred twenty-three consecutive patients hospitalized for acute HF (mean age 74.8 years; 57% female) were recruited and followed for 36 months after hospitalization.At multivariate Cox model, only inferior vena cava (IVC) diameter and mean arterial pressure (MAP) registered bed-side on admission, resulted, after correction for all confounders factors, the sole factors significantly associated with a higher risk of all-cause mortality in long-term (H…
Obesity and reduction of the response rate to anti-tumor necrosis factor α in rheumatoid arthritis: an approach to a personalized medicine.
2013
Objective Obesity is a mild, long-lasting inflammatory disease and, as such, could increase the inflammatory burden of rheumatoid arthritis (RA). The study aim was to determine whether obesity represents a risk factor for a poor remission rate in RA patients requiring anti–tumor necrosis factor α (anti-TNFα) therapy for progressive and active disease despite treatment with methotrexate or other disease-modifying antirheumatic drugs. Methods Patients were identified from 15 outpatient clinics of university hospitals and hospitals in Italy taking part in the Gruppo Italiano di Studio sulle Early Arthritis network. Disease Activity Score in 28 joints (DAS28), body mass index (BMI; categorized …
A comparison of efficacy and safety of an ezetimibe/simvastatin combination compared with other intensified lipid-lowering treatment strategies in di…
2013
The low-density lipoprotein cholesterol (LDL-C) lowering efficacy of switching to ezetimibe/simvastatin (EZ/S) 10/20 mg versus doubling the run-in statin dose (to simvastatin 40 mg or atorvastatin 20 mg) or switching to rosuvastatin 10 mg in subjects with cardiovascular disease (CVD) and diabetes was assessed. Endpoints included percentage change in LDL-C and percentage of patients achieving LDL-C <70 mg/dL. Significantly greater reductions in LDL-C occurred when switching to EZ/S versus statin doubling in the overall population and in subjects treated with simvastatin 20 mg or atorvastatin 10 mg (all p < 0.001). The LDL-C reduction was numerically greater when switching to EZ/S vers…
Linguistic and spatial skills predict early arithmetic development via counting sequence knowledge
2013
Utilizing a longitudinal sample of Finnish children (ages 6-10), two studies examined how early linguistic (spoken vs. written) and spatial skills predict later development of arithmetic, and whether counting sequence knowledge mediates these associations. In Study 1 (N = 1,880), letter knowledge and spatial visualization, measured in kindergarten, predicted the level of arithmetic in first grade, and later growth through third grade. Study 2 (n = 378) further showed that these associations were mediated by counting sequence knowledge measured in first grade. These studies add to the literature by demonstrating the importance of written language for arithmetic development. The findings are …
Validating rationale of group-level component analysis based on estimating number of sources in EEG through model order selection
2012
This study addresses how to validate the rationale of group component analysis (CA) for blind source separation through estimating the number of sources in each individual EEG dataset via model order selection. Control children, typically reading children with risk for reading disability (RD), and children with RD participated in the experiment. Passive oddball paradigm was used for eliciting mismatch negativity during EEG data collection. Data were cleaned by two digital filters with pass bands of 1-30 Hz and 1-15 Hz and a wavelet filter with the pass band narrower than 1-12 Hz. Three model order selection methods were used to estimate the number of sources in each filtered EEG dataset. Un…
The development and predictive relations of play and language across the second year
1999
The play and language development of 171 toddlers was examined at 14 and 18 months by observing their activities on the Symbolic Play Test and by assessing their language skills using the MacArthur Communicative Development Inventories (MCDI) and the Reynell Developmental Language Scales. Additionally, data from the Bayley Scales of Infant Development and the MCDI were obtained at 24 months, in order to investigate how play and language measures taken at 14 and 18 months predict children's development at the age of 2 years. The results showed that the vocabulary production and symbolic play of the 14-month-old toddlers made a unique contribution to their language and cognitive skills at the…
White blood cell counts as risk markers of developing metabolic syndrome and its components in the Predimed study.
2013
Journal Article; Multicenter Study; Randomized Controlled Trial; Research Support, Non-U.S. Gov't; TRIAL REGISTRATION Controlled-Trials.comISRCTN35739639. BACKGROUND The Metabolic Syndrome (MetS) is a cluster of metabolic abnormalities that includes hyperglucemia, hypertension, dyslipidemia and central obesity, conferring an increased risk of cardiovascular disease. The white blood cell (WBC) count has been proposed as a marker for predicting cardiovascular risk. However, few prospective studies have evaluated the relationship between WBC subtypes and risk of MetS. METHODS Participants were recruited from seven PREDIMED study centers. Both a baseline cross-sectional (n = 4,377) and a prospe…
