# Sport and Physical Activity Participation by Weight Groups in School-Aged Hungarian Children
## 4 Discussion  
The aims of this study were to collect data about school children's overall physical activity and their participation in organized sport and active transportation, and then \begin{table}
\begin{tabular}{c c c c c} \hline \hline  & **Underweight** & **Healthy** & **Overweight** & **Obese** \\ \hline \multirow{3}{*}{Club sport} & Football (36\%) & Football (21\%) & Martial arts (31\%) & Football (31\%) \\ \cline{2-5}  & Kayaking \& Canoeing (13\%) & Dance (15\%) & Handball (17\%) & Martial arts (19\%) \\ \cline{2-5}  & Martial arts (13\%) & Martial arts (13\%) & Football (10\%) & Handball (15\%) \\ \hline \multirow{3}{*}{Organized sport} & Football (26\%) & Dancing (14\%) & Swimming (15\%) & Football (36\%) \\ \cline{2-5}  & Swimming (14\%) & Football (10\%) & Football (15\%) & Working out in gym (14\%) \\ \cline{2-5}  & Basketball (14\%) & Swimming (8\%) & Basketball (15\%) & Gymnastics (9\%) \\ \hline \multirow{3}{*}{Activity with parents} & Cycling (59\%) & Cycling (52\%) & Cycling (51\%) & Cycling (50\%) \\ \cline{2-5}  & Walking (31\%) & Walking (32\%) & Walking (42\%) & Walking (30\%) \\ \cline{1-1} \cline{2-5}  & Football (23\%) & Football (8\%) & Football (13\%) & Football (18\%) \\ \hline \hline \end{tabular}
\end{table} 
Table 4: Order of preferred sports and physical activities and ratios in different weight status. \begin{table}
\begin{tabular}{l c c c} \hline \hline  & **Odds Ratio for Obesity** & **CI (95\%)** & \(p\) \\ \hline Achieving MVPA \textgreater{} 60 min/day & 0.74 & 0.40–1.37 & 0.34 \\ \hline Club sport or organized sport & 0.56 & 0.34–0.91 & \textless{}0.02 \\ \hline Active transport & 0.97 & 0.46–2.05 & 0.95 \\ \hline Activity with parents & 0.67 & 0.37–1.20 & 0.18 \\ \hline Parental support & 0.75 & 0.28–1.98 & 0.56 \\ \hline Higher education of parents & 0.25 & 0.14–0.43 & \textless{}0.01 \\ \hline Residency (capital, county seat, or town) & 0.83 & 0.48–1.39 & 0.48 \\ \hline Significance was calculated with binary logistic regression. & & & \\ \end{tabular}
\end{table} 
Table 3: Odds ratios for obesity in different factors affecting physical activity. compare the results between the different weight classifications. We also tried to identify significant factors that could be used in obesity prevention interventions for Hungarian children. To our knowledge, this is the first study that reports children's sport and physical activity participation rates and the joint activity of parents and children based on weight status in Hungary. Hungary has the highest obesity rate in Europe and the fifth highest prevalence of obesity in the world. In Hungary, as in other countries with relatively high proportions of overweight and obese adults, the rates have increased by about 1% annually. According to the Organization for Economic Co-operation and Development [22], 33% of Hungarian adults are obese and 67% are obese or overweight. The prevalence (22%) of overweight and obese children and youth in our study was higher than previously published (20%) in the Health Behaviour in School-aged Children (HBSC) study but closer to another Hungarian study in which the prevalence was 23% [2,23]. The rate of children and adolescents who achieved the minimum 60 min of daily moderate-to-vigorous physical activity in our study was 77%, which is much higher than published in the HBSC global report earlier or in Polish adolescents (17%) [24]. In the Global Matrix 4.0 report, the average of 57 countries was lower (27-33%) [9]. Our results are in agreement with those of a study conducted in Slovakia where 66% of adolescents met the PA recommendation [25]. An explanation might be that in Hungary, a national physical education curriculum including five sessions of 45 min per week (1 per weekday) and recommendations for extracurricular PA as well as school sports programs were gradually introduced in 2012 in all Hungarian schools.
