The Influence of Kindergarten Environment on the Development of Preschool Children’s Physical Fitness
The aim of this research is to find out to what extent the special qualifications of physical education teachers and the physical environment of kindergartens influence the physical development of preschoolers. Forty-four kindergartens across Estonia participated in the study, half of which had a physical education teacher (PEt), whereas the remaining 22 kindergartens were taught by non-qualified kindergarten teachers (NoPEt). Six Eurofit fitness…
A cross-national comparison of problematic gaming behavior and well-being in adolescents
Background and aims. The popularity of playing games among adolescents has increased during the last decades, possibly affecting the prevalence of problematic gaming behavior. The current study aimed to compare country-level prevalence rates of adolescents' problematic gaming behavior in five countries and identify cross-cultural similarities and differences in the relationship between problematic gaming and well-being (life satisfaction, psychol…
The Influence of Previous Lifestyle on Occupational Physical Fitness in the Context of Military Service
The Estonian Defense Forces are the basis of military service, mandatory for all male citizens of the Republic of Estonia who are at least 17 years old. The physical load in military service, especially in the first stage, is significantly greater than for men in everyday life. Therefore, it is important to know if health promotion in civilian life adequately prepares young people for military service and to what extent pre-military health behavi…
Trends in Adolescent Substance Use
The findings on the prevalence of substance use among adolescents from 1994 to 2018 revealed that the Baltic states and Poland have faced relatively different temporal trends. These countries might be facing new public health challenges in a near future, e.g., use of electronic cigarettes and cannabis use among adolescents
Physical Activity and Sports Participation among Adolescents
The impact of physical activity and sport on the development of adolescents' knowledge and attitudes has not been studied sufficiently. We assume that young people with more knowledge of sports will continue to be physically active on their own. The aim of this study is to identify the differences in the sports and physical activity-related knowledge and attitudes of adolescents who engage in organised sports training and those who do not. A tota…
Baltic Adolescents’ Health Behaviour
The aim of the study is to assess the time trends in Baltic adolescents' physical activity, dietary habits and BMI and compare the results with the average of the Health Behaviour in School-aged Children (HBSC) study. The research used HBSC data from 2006 to 2018. The total number of respondents was 17,458 in Estonia, 18,416 in Latvia and 20,466 in Lithuania. A logistic regression analysis was applied to estimate time trends in health behaviour i…
Changes in anthropometrical characteristics during two years in 6 year old children
The purpose of this study was to investigate changes in anthropometrical characteristics during the last year (autumn-spring) in preschool and first year (autumn-spring) in school. Changes in anthropometrical characteristics during summer months were also studied (spring-autumn). The subjects were 130 boys and 122 girls, 6 years of age at the beginning of the investigation. The body height and mass were measured and the BMI (kg/m2) was calculated…
Assessment of motor ability of 4- and 5-year-old children
The aim of this investigation was to develop a test battery to measure the motor abilities of 4- and 5-year-old children. The subjects were 932 healthy kindergarten children from Tartu, Estonia: boys, 4 years, n = 205; boys, 5 years, n = 267; girls, 4 years, n = 224; girls, 5 years, n = 236. Height and body mass were measured, and the body mass index (BMI, kg/m2) was calculated. The following motor ability tests were used: 3-min run (cardiorespir…
