The effects of muscle mass and muscle quality on cardio-metabolic risk in peripubertal girls: a longitudinal study from childhood to early adulthood.

2017

Increased cardio-metabolic risk is well documented in children and adolescents with obesity and normal weight obesity (NWO). However, the associations of muscle mass and muscle quality with cardio-metabolic risk, independent of weight status from childhood to adulthood, has not been examined. A total of 236 girls were followed from pre-puberty to early adulthood. Fat mass (FM) and lean mass (LM) of the whole body were assessed by a dual-energy X-ray absorptiometry; muscle cross-sectional area (mCSA), muscle density (mDen; skeletal muscle fat content) of the lower leg by the peripheral quantitative computerized tomography; and blood glucose, insulin, triglycerides and high-density lipoprotei…

Verbal counting skill predicts later math performance and difficulties in middle school

2019

This study examined the role of verbal counting skill as an early predictor of math performance and difficulties (at or below −1.5 standard deviation in basic math skills) in middle school. The role of fourth-grade level arithmetical skills (i.e., calculation fluency, multi-digit arithmetic i.e. procedural calculation, and word problem solving) as mediators was also investigated. The participants included 207 children in central Finland who were studied from kindergarten to the seventh grade. Path modeling showed that verbal counting in kindergarten is a strong predictor for basic math performance in seventh grade, explaining even 52% of the variance in these skills after controlling for th…

A longitudinal study on the information needs and preferences of patients after an acute coronary syndrome.

2016

Background Research has shown that the provision of pertinent health information to patients with cardiovascular disease is associated with better adherence to medical prescriptions, behavioral changes, and enhanced perception of control over the disease. Yet there is no clear knowledge on how to improve information pertinence. Identifying and meeting the information needs of patients and their preferences for sources of information is pivotal to developing patient-led services. This prospective, observational study was aimed at exploring the information needs and perceived relevance of different information sources for patients during the twenty-four months following an acute coronary synd…

Latvijas ģimenes paaudzēs, 2018

2019

Pētījums aptver visas vecuma grupas: gan jaunus cilvēkus patstāvīgās dzīves sākumā (no 18 gadu vecuma), gan pieredzes bagātus — citās vecuma grupās (līdz 79 gadu vecumam), sniedzot precīzu informāciju par cilvēka dzīves galvenajiem demogrāfiskajiem notikumiem un cikliem vairāku paaudžu dzīvē, sākot jau no 1950. gadu vidus. Aptaujā tiek iegūta informācija par šādām tēmām: pāreja uz pieaugušo dzīvi (mācības un darbs, vecāku mājas atstāšana, pirmās partnerattiecības, jaunas ģimenes veidošana, labklājība un trūkums; kopdzīve un ģimenes stabilitāte (daudzveidīgās ģimenes formas, balanss starp darbu un ģimeni, pienākumu sadale starp vīriešiem un sievietēm,…

Antisocial and human capital pathways to socioeconomic exclusion: A 42-year prospective study.

2017

Nordic welfare states have been very successful at reducing poverty and inequality among their citizens. However, the presence of a strong social safety net in these countries has not solved the problem of socioeconomic exclusion, manifesting in such outcomes as chronic unemployment and welfare dependency. In an effort to understand this phenomenon, the current study builds on the assumption that psychological risk factors emerge as important determinants of socioeconomic disadvantage in an environment where ascribed characteristics have less impact on educational and occupational attainment. Using data from Finland, this research examined a life course model linking childhood differences i…

Association of leisure time physical activity and NMR-detected circulating amino acids in peripubertal girls: A 7.5-year longitudinal study

2017

AbstractThis study investigated the longitudinal associations of physical activity and circulating amino acids concentration in peripubertal girls. Three hundred ninety-six Finnish girls participated in the longitudinal study from childhood (mean age 11.2 years) to early adulthood (mean age 18.2 years). Circulating amino acids were assessed by nuclear magnetic resonance spectroscopy. LTPA was assessed by self-administered questionnaire. We found that isoleucine, leucine and tyrosine levels were significantly higher in individuals with lower LTPA than their peers at age 11 (p < 0.05 for all), independent of BMI. In addition, isoleucine and leucine levels increased significantly (~15%) fro…

Longitudinal Physical Activity, Body Composition, and Physical Fitness in Preschoolers

2017

Purpose: This study aimed to investigate longitudinal associations of objectively measured physical activity (PA) and sedentary behavior (SB) with body composition and physical fitness at a 12-month follow-up in healthy Swedish 4-yr-old children. Methods: The data from the population-based MINISTOP trial were collected between 2014 and 2016, and this study included the 138 children who were in the control group. PA and SB were assessed using the wrist-worn ActiGraph (wGT3x-BT) accelerometer during seven 24-h periods and, subsequently, defined as SB, light-intensity PA, moderate-intensity PA, vigorous-intensity PA (VPA), and moderate-to-vigorous PA (MVPA). Body composition was measured using…

Qualitative Longitudinal Research in Health Research: A Method Study

2022

Abstract Background Qualitative longitudinal research (QLR) comprises qualitative studies, with repeated data collection, that focus on the temporality (e.g., time and change) of a phenomenon. The use of QLR is increasing in health research since many topics within health involve change (e.g., progressive illness, rehabilitation). A method study can provide an insightful understanding of the use, trends and variations within this approach. The aim of this study was to map how QLR articles within the existing health research literature are designed to capture aspects of time and/or change. Methods This method study used an adapted scoping review design. Articles were eligible if they were wr…

Examining pre-service teachers' Technological Pedagogical Content Knowledge as evolving knowledge domains : A longitudinal approach

2019

The aim of this study is to outline the development and changes in pre‐service teachers' technological pedagogical content knowledge (TPACK) assessments during the first 3 years in teacher education. Specifically, research was conducted at three measurement points over a 3‐year teacher education period. The target group consisted of pre‐service teachers (N = 148) from three Finnish universities. Results indicate a growth in confidence related to all TPACK areas during the research period. The strongest gains were in pedagogical content knowledge. In addition, the gains were larger in other areas related to pedagogical knowledge than areas related to technology or content knowledge. In areas…
