# Sport and Physical Activity Participation by Weight Groups in School-Aged Hungarian Children
## 2 Materials and Methods  
Prior to any data collection, ethical approval was received from the Hungarian University of Sports Science (MTSE-OKE KEB/08/2023). This study was a cross-sectional survey study. The data were collected in spring 2023 using social media platforms and internet correspondence. The research project and survey were sent to 1247 principals of primary schools and were shared in parental online groups. The survey started with an introduction for parents in which the inclusion criteria were written. Inclusion was being a parent of a school-age child (6-15 years old). To avoid bias, an increased sample size and the diversity of residency were targeted. After data cleaning the online data collection, 677 parents (42.8 \(\pm\) 6.4 years old) provided information about 677 children (10.9 \(\pm\) 2.5 years old). The 677 results (345 boys and 332 girls) were achieved from 611 different IP addresses. The identical IP addresses might be explained by family membership, meaning a parent filled in the questionnaire for more than one child. Informed consent was the first part of the questionnaire that was obtained from all participants prior to answering the questionnaire. Our questionnaire was completed with the Qualtrics program and contained 37 questions. Parents completed this self-report questionnaire that captured the parent's age, sex, education, and residency and their child's sex, age, body height, weight, and physical activity behaviour. In this report, we analyse the demographic variables and nine questions connected to physical activity. The questionnaire was compiled using the global matrix (GM) 4.0 indicators, definitions, and benchmarks [12]. The GM methods and physical activity indicator benchmarks for children and adolescents were published by [PERSON] et al. (2022) [10]. The global matrix on PA for children is an initiative launched under the leadership of the Active Healthy Kids Global Alliance (AHKGA) to achieve a comprehensive understanding of the global variation in child and adolescent PA, related indicators, and key sources of influence. As an overall physical activity indicator, we wanted to know what percentage of children and youth meet the global health-related physical activity recommendation. The question was \"Do you think your child accumulates at least 60 min of moderate-vigorous physical activity per day on average?\" \"Yes/No\". We used recommended questions for the organized sport, physical activity, active transportation, and family and peers indicators. The questions for club sport were \"Does your child participate in club sport?\", \"Yes/No\", \"If yes, what kind of sport?\"; \"Does your child participate in organized sport but not in a sport club? (in school or afterschool)\", \"Yes/No\", \"If yes, what kind of organized sport?\"; \"Does your child use active transportation to get to and from places? (walk, cycling, scooter, or other)\", \"Yes/No\"; \"Do you do physical activity together with your child?\", \"Yes/No\", \"If yes, what kind of activity?\"; \"Do you facilitate physical activity and sport opportunities for your child? (driving, volunteering, cheering, paying membership fees)\", \"Yes/No\". The weight status categories (underweight, healthy, overweight, obese) were determined by the World Health Organization (WHO)'s age- and gender-specific reference using the calculated body mass index [21]. For the odds ratio calculation, we needed two categories in which Yes/No questions were obvious, but in parental education or residency, we had to separate the results into two main groups. Those who reported attaining some college degree or postgraduate degree became part of a higher-educated group, and those who reported completing high school, some high school, or less than a high school education, remained in the other group. Two categories were created from all residency locations based on type: The capital of Hungary, county seats, and towns comprised one group. The municipalities, villages, and farms comprised the second group.
