Social and demographic factors of physical activity in 9-11 years old slovenian children

Factors related to physical behaviour of children are important in understanding the characteristics of their physical activity. Apart from the factors of physical environment, social and demographical factors are also related to physical activity levels. Randomly selected 669 children (9.9±0.8 years; 48.8% boys) from randomly selected Slovenian elementary schools participated in this study. All data were obtained during a single measurement in May 2010. The standardized questionnaire The Quality of Life Survey was used to measure physical activity (PA) levels as well as social and demographic factors which could be associated with it. The results indicated higher PA levels in boys than in girls (704±286 min/week vs. 617±268 min/week; p<.001). The analysis of variance confirmed higher PA levels in girls with parents of a higher socioeconomic status (SES) (p=.0018); in boys, there were no differences in PA levels according SES (p=.580). In both the boys (p=.047) and girls (p=.021) PA levels were higher if their whole family were members of any sport club. However, family structure was not related to PA levels in either boys (p=.648) or girls (p=.132). In boys, the bi-variate regression analysis showed a positive correlation with mother’s educational level (r=.090), with the number of children in the family (r=.150), with the child’s attitude that active commute to school is attractive (r=.108) and that child’s peers actively commute to school (r=.129), whereas a negative correlation was obtained with fear the child would become a victim of violence or harassment on the way to school (r=-.097). In girls, bi-variate regression analysis showed a positive correlation with mother’s educational level (r=.094), with the child’s attitude that active commute to school is attractive (r=.092) and that child’s peers actively commute to school (r=.221), whereas a negative correlation was established with fear the child would become a victim of violence or harassment on the way to school (r=-.061) or at recreational and sporting facilities (r=-.046). According to low correlations in bi-variate analysis, we conclude that other factors, such as, for example, physical environment, might be strongly related to physical activity levels in children and need to be taken into account when preparing interventions for physical activity enhancement

The Impact of Two Hours of Athletics Weekly on the Physical / Sporting Activity for Children

The purpose of our study was to investigate if organised physical activity of athletics increase the overal amount and intensity of physical activity during and after an athletics session. Using an accelereometer we measured weekly physical activity in 22 children (11 boys, aged 6.6 ± 1.2 years), including two hours of organised athletics. During athletics physical activity reached 1787 ± 620 (without athletics 615,5 ± 116,6) counts/minute, with most prevalent physical inactivity (29 ± 11,7 minutes) and moderate to vigorous physical activity (19,0 ± 8,9 minutes). Two weekly hours of athletics increased average daily time of moderate to vigorous physical activity (16 %; P < 0,001) and decreased the time of physical inactivity (–10 %; P < 0,001). Athletics contrbutes to achieving physical activity norms; however, more focus should be placed on increasing the intensity of physical activity during organised hours of athletics
