Background/aim: The aim was to assess the differences between physical activity and physical fitness in obese, overweight, and normalweight children. Materials and methods:The cross-sectional study was accomplished using cluster sampling method at 3 Lithuanian schools. An analysis of anthropometric data for 532 Lithuanian children was performed. Height, weight, waist and hip circumferences, and skinfold thickness were measured. Body mass index, waist-to-hip ratio, and body fat percentage were calculated. The Youth Physical Activity Questionnaire and a 6-min walk test (6MWT) were administered to evaluate physical activity and physical fitness. Maximal oxygen consumption was calculated to assess the children's aerobic capacity. Correlations among anthropometric data, 6MWT-walked distance, and moderate-vigorous physical activity duration were analyzed. Results:The study showed that 20.1% of the studied children were obese or overweight. They engaged in moderate-to-vigorous physical activity 22.4 min less per day and walked 50.9 m less on average during a 6-min test than normal-weight children. Physical fitness parameters correlated with daily moderate-vigorous physical activity duration and with most of the children's anthropometric parameters. Conclusion:Obese and overweight children were less physically active and had lower physical fitness than normal-weight children. The findings underline the need for interventions to increase physical activity and improve fitness in obese and overweight children.

Road traffic injury remains a serious public health problem in children and young people in Lithuania, which requires a high priority.

The objectives of the study were to estimate mortality rate trends due to road traffic, drowning and fire/burns in children aged 0-14 years and in adolescents aged 15-19 years in Lithuania between the years 1971-2005. The data were obtained from Statistics Lithuania and the Health Information Centre. Trends were estimated by linear and polynomial regression. The study revealed that the child and adolescent unintentional injury mortality rates show declining trends. For children, the significant decreasing trends of mortality rates due to road traffic, drowning and fire/burns were observed. For adolescents there were significant decreasing trends for drowning deaths, and insignificant decreasing tendencies for deaths from fire/burns. There was an insignificant increased road traffic mortality rate trend for adolescent girls. For the adolescent boys group and for boys and girls together from the beginning of the study period there were increasing trends, followed by declining trends. In the last years, the increase was observed again.

During the last two decades, the number of macrocell mobile telephony base station antennas emitting radiofrequency (RF) electromagnetic radiation (EMR) in residential areas has increased significantly, and therefore much more attention is being paid to RF EMR and its effects on human health. Scientific field measurements of public exposure to RF EMR (specifically to radio frequency radiation) from macrocell mobile telephony base station antennas and RF electromagnetic field (EMF) intensity parameters in the environment are discussed in this article. The research methodology is applied according to the requirements of safety norms and Lithuanian Standards in English (LST EN). The article presents and analyses RF EMFs generated by mobile telephony base station antennas in areas accessible to the general public. Measurements of the RF electric field strength and RF EMF power density were conducted in the near- and far-fields of the mobile telephony base station antenna. Broadband and frequency-selective measurements were performed outside (on the roof and on the ground) and in a residential area. The tests performed on the roof in front of the mobile telephony base station antennas in the near-field revealed the presence of a dynamic energy interaction within the antenna electric field, which changes rapidly with distance. The RF EMF power density values on the ground at distances of 50, 100, 200, 300, 400, and 500 m from the base station are very low and are scattered within intervals of 0.002 to 0.05 μW/cm2. The results were compared with international exposure guidelines (ICNIRP).

Due to the multifactorial etiology of scoliosis, a comprehensive treatment plan is essential for conservative management. Physiotherapeutic scoliosis-specific exercise (PSSE) methods have lately gained popularity for the conservative treatment of scoliosis. The aim of this study was to analyze the PSSE methodologies used for conservative treatment of adolescent idiopathic scoliosis (AIS), as well as their effectiveness. The study was based on an extended literature search conducted in the PubMed, Google Scholar, PEDro, eLABA, and BioMed Central databases. A total of 123 articles were selected for this study (including articles overviewed in systematic reviews and meta-analyses) after applying the inclusion criteria. The study revealed that inappropriate management of AIS could result in serious health problems. Conservative interventions that aid in stabilizing spine curvature and improving esthetics are preferred for scoliosis treatment. Bracing has traditionally been the mainstay of treatment, but growing evidence suggests that PSSE physiotherapy allows effective management of idiopathic adolescent scoliosis. Currently, there are the following PSSE physiotherapy schools in Europe: Schroth, SEAS, BSPTS, FED, FITS, Lyon, Side Shift, and DoboMed. The methodologies of these schools are similar, in that they focus on applying corrective exercises in three planes, developing stability and balance, breathing exercises, and posture awareness. Although high-quality research supporting the effectiveness of PSSE physiotherapy in the treatment of AIS is lacking, existing evidence indicates that PSSE physiotherapy helps to stabilize spinal deformity and improve patients’ quality of life. Among the abovementioned methodologies, Schroth is the most widely studied and has been proven to be effective. However, both SEAS and BSPTS effectively stabilize and even reduce the Cobb angle of scoliosis. Data supporting the validity of other methodologies are very limited. Only the Schroth method significantly reduces the angle of trunk rotation, while both SEAS and Schroth methods greatly improve the quality of life indicators. In any case, the available evidence is insufficient to confirm the advantage of one specific physiotherapy technique over others.

SummaryChildren leisure time is usually decided by their immediate environment, i.e. their family. Therefore, leisure activities which are designed in a family and which enable children to discover pleasant experiences and motivate them to care of their own health are of extreme importance. The aim of the study was to highlight the peculiarities of the organization of leisure time activities in a family for elementary school students in the context of health education. The respondents of the study were 614 elementary school students from eight Western Lithuania schools and 604 of their parents. The study has shown that elementary school students rate their health more favourably than their parents. Almost half of the respondents-children (42.7%) have rated their health as very good and around the same number of children (45.3%) have rated it as good. One fifth of respondents-parents (20.7%) have rated the health of their children as very good and more than half of parents (62.3%) have said that the health of their children is good. The opinion of parents and their children on the issue of the time allocated for leisure activities has been discovered as being similar. Respondentschildren indicate that on weekdays their leisure time averages to 2.4 hours/day and at the weekends to 4.3 hours/day. Respondents-parents indicate that children's leisure time on weekdays lasts for 2.2 hours/ day, and at the weekends it reaches 4.4 hours /day. It has been revealed that the longer the leisure time the children have, the better their health is. The majority of children (78%) believe that they have enough leisure time. Those, who assume that they do not have enough leisure time, and those, who are undecided, make almost one-fourth (24%). A third of elementary school students enjoy physically active forms of leisure time activities (going in for sports) while about a half of respondents-children prefer passive forms
