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.

9-11岁斯洛文尼亚儿童体育锻炼的社会和人口统计学因素

与儿童的身体行为有关的因素对于理解他们的身体活动的特征很重要。除身体环境因素外，社会和人口因素也与体育活动水平有关。随机选择斯洛文尼亚小学的669名儿童（9.9±0.8岁；男孩为48.8％）参加了这项研究。所有数据都是在2010年5月的一次测量中获得的。标准化问卷“生活质量调查”用于测量身体活动（PA）水平以及与之相关的社会和人口统计学因素。结果表明，男孩的PA水平高于女孩（704±286分钟/周，女性为617±268分钟/周； p <.001）。方差分析证实，具有较高社会经济地位（SES）的父母的女孩的PA水平较高（p = .0018）；在男生中，根据SES，PA水平无差异（p = .580）。如果男孩（p = .047）和女孩（p = .021）的全家都是运动俱乐部的成员，则PA水平较高。然而，男孩（p = .648）或女孩（p = .132）的家庭结构与PA水平无关。在男孩中，双变量回归分析显示出与母亲的受教育程度（r = .090），家庭中的孩子数（r = .150），与孩子积极上学的态度正相关的正相关性。 （r = .108），并且那个孩子的同龄人积极上下班（r = .129），而由于担心孩子在上学途中会成为暴力或骚扰的受害者而获得负相关（r =-。097）。在女孩中，双变量回归分析显示与母亲的受教育程度呈正相关（r = .094），并且与儿童的态度表明，积极通勤上学（r = .092）和孩子的同龄人积极通勤上学（r = .092）。 = .221），而由于担心孩子在上学途中（r =-。061）或娱乐和体育设施（r =-。046）时会成为暴力或骚扰的受害者而建立了负相关关系。根据双变量分析中的低相关性，我们得出结论，其他因素（例如物理环境，可能与儿童的体育活动水平密切相关，因此在准备增强体育活动的干预措施时应予以考虑。关键词：儿童，青少年，社会经济地位，通勤
