Sense of coherence and health: evidence from two cross-lagged longitudinal samples
2000
We explored the stability of sense of coherence (SOC) and the relationship between SOC and health in two cross-lagged longitudinal samples by using structural equation modeling. In Study 1, comprising 577 municipal male and female employees, SOC was found to be stable in both sexes. In women, SOC significantly predicted sickness absences in the 4-year follow-up period. A low SOC, but not a high SOC, was associated with health prospects. Surprisingly, SOC did not influence sickness absences among men. Study 2 further tested the relationship between SOC and health in 320 male technical designers. Although SOC was cross-sectionally associated with psychological and somatic health complaints, i…
Sport disciplines, types of sports, and waist circumference in young adulthood – a population-based twin study
2017
Purpose: The benefits of physical activity (PA) in preventing abdominal obesity are well recognized, but the role of different sport disciplines remains open. We aimed, therefore, to investigate how participation in different sport disciplines, and the number and types of sports engaged in are associated with waist circumference (WC) in young adulthood. Methods: This population-based cohort study comprised 4027 Finnish twin individuals (1874 men), with a mean age of 34 y (32-37), who answered a survey, including self-measured WC. We extracted the number and identified the types (aerobic, power, and mixed) of the different sport disciplines respondents reported participating in. Results: The…
Conceptual implicit memory: a developmental study.
1995
The widely accepted standpoint that implicit memory emerges earlier in development than explicit memory, and is more stable from childhood to adult age, is based on experimental data essentially collected in perceptual tasks. The present study was aimed at investigating whether these findings still hold when a more conceptual task is used. We compared the performance of children at two age levels (2nd and 4th grades) on a category-exemplar generation task. Results showed that performances of the two groups were comparable when the target items were typical of their categories, as in Experiment 2, and for a subset of the items in Experiment 1. However, the older children outperformed the you…
Associations between Teacher- and Student-directed Sexual and Physical Violence in Physical Education.
2020
This study examined relationships between teachers’ perceptions of verbal and non-verbal sexual harassment and physical violence against teachers and among students in physical education (PE). Participants were 175 (females 122, males 53) Finnish PE teachers between 27 and 62 years ( M = 44.8 ± 9.2 years). The cross-sectional data were collected by an anonymous online survey in the fall semester 2018. The findings showed that (a) higher levels of verbal sexual harassment and physical violence among students were associated with higher levels of equivalent types of violence against PE teachers, (b) higher levels of verbal and non-verbal sexual harassment among students were associated with …
Math anxiety and its relationship with basic arithmetic skills among primary school children
2017
Background Children have been found to report and demonstrate math anxiety as early as the first grade. However, previous results concerning the relationship between math anxiety and performance are contradictory, with some studies establishing a correlation between them while others do not. These contradictory results might be related to varying operationalizations of math anxiety. Aims In this study, we aimed to examine the prevalence of math anxiety and its relationship with basic arithmetic skills in primary school children, with explicit focus on two aspects of math anxiety: anxiety about failure in mathematics and anxiety in math-related situations. Sample The participants comprised 1…
Two-year changes in quality of life in elderly patients with low-energy hip fractures. A case-control study
2010
Background The long-term effect of hip fracture on health-related quality of life (HRQOL) and global quality of life (GQOL) has not been thoroughly studied in prospective case-control studies. Aims a) to explore whether patients with low-energy hip fracture regain their pre-fracture levels in HRQOL and GQOL compared with changes in age- and sex-matched controls over a two year period; b) to identify predictors of changes in HRQOL and GQOL after two years. Methods We examined 61 patients (mean age = 74 years, SD = 10) and 61 matched controls (mean age = 73 years, SD = 8). The Short Form 36 assessed HRQOL and the Quality of Life Scale assessed GQOL. Paired samples t tests and multiple linear …
A potential real-time procedure to evaluate correlation of recordings among single trials (CoRaST) for mismatch negativity (MMN) with Fourier transfo…
2011
Abstract Objective To design a fast algorithm that evaluates the degree of correlation of recordings among single trials (CoRaST) for mismatch negativity (MMN) activity. Methods The participants were 114 children, aged 8–16 years. MMNs were elicited by two deviants in duration that occurred in an uninterrupted sound within a passive oddball paradigm, and each trial lasted 650 ms with 130 samples. CoRaST was derived from the frequency-domain MMN model through Fourier transformation. To validate the effectiveness of the proposed method, the wavelet transformation-based inter-trial coherence (ITC) was taken as a reference. Results Performances of the proposed CoRaST and ITC were similar in eva…
Effect of Concurrent Visual Feedback Frequency on Postural Control Learning in Adolescents.
2018
The purpose was to find better augmented visual feedback frequency (100% or 67%) for learning a balance task in adolescents. Thirty subjects were divided randomly into a control group, and 100% and 67% feedback groups. The three groups performed pretest (3 trials), practice (12 trials), posttest (3 trials) and retention (3 trials, 24 hours later). The reduced feedback group showed lower RMS in the posttest than in the pretest (p = 0.04). The control and reduced feedback groups showed significant lower median frequency in the posttest than in the pretest (p < 0.05). Both feedback groups showed lower values in retention than in the pretest (p < 0.05). Even when the effect of feedback frequenc…
Enhanced development of auditory change detection in musically trained school-aged children: a longitudinal event-related potential study
2013
Adult musicians show superior auditory discrimination skills when compared to non-musicians. The enhanced auditory skills of musicians are reflected in the augmented amplitudes of their auditory event-related potential (ERP) responses. In the current study, we investigated longitudinally the development of auditory discrimination skills in musically trained and nontrained individuals. To this end, we recorded the mismatch negativity (MMN) and P3a responses from children who play a musical instrument and age-matched children with no musical training at ages 7, 9, 11, and 13. Basic auditory processing was investigated by recording ERPs in the Multi-Feature Paradigm that included frequency, du…
Homocysteine and MTHFR C677T polymorphism in children and adolescents with psychotic and mood disorders
2013
High level of homocysteine (Hcy) is risk factor of schizophrenia and mood disorders.The aim was to detect a serum level of Hcy, examine the associations between the level of Hcy, methylenetetrahydrofolate reductase (MTHFR) gene C677T polymorphism and clinical properties for patients with schizophrenia, mood disorders and in a control group.There were 88 patients with schizophrenia, 28 with affective disorders and 94 from the control group. The Hamilton Anxiety Scale (HAM-A) was performed to study anxiety, the Hamilton Depression Scale (HAM-D) to study depression and the Brief Psychiatric Rating Scale (BPRS) to study severity of schizophrenia. The level of Hcy was stated by isocratic high-pe…
