PT Journal AU Tomanova, J Kikalova, K TI Back pain in children and adolescent SO Profese Online PY 2017 BP 10 EP 17 VL 10 IS 2 DI 10.5507/pol.2017.005 DE back; pain; survey; students; physical activity AB Background: Regular physical activity promotes health and prevents the development of many diseases. The prevalence of sedentary lifestyle related to physical inactivity in children and adolescents increases with the decline of the needs and opportunities to be physically active. Aim: The aim of this study was to determine whether the respondents suffer from back pain. Methods: The total number of respondents was 5,433. The respondents' age ranged from 6 to 21 years. There were 49.7% girls and 50.3% boys. The research survey was of a quantitative nature. The data was collected using a non-standardized questionnaire focused on the healthy lifestyle of children and youth. The Statistica 10.0 program (StatSoft, Tulsa, OK) was used for statistical processing. The Pearson's chi-quadrate test was used to analyse the obtained data. Data was also evaluated using the Regulated Residues with 5% level of significance. Results: The girls in the questionnaire survey (58.5%) reported more back pain than boys (36.5%). Girls suffer from back pain 1.6x more often than boys. Almost half of the respondents suffer from back pain as 47% of all respondents said their back was hurting. Both girls and boys are involved in some physical activity for 31-60 minutes a day. When performing high body activity (181+ minutes / day), the back pain more affects girls (78.2%) than boys (39.5%). Approximately the same percentage of girls (37.7%) and boys (40.7%) spend 241 and more minutes a day in body passivity. There is a dependence in the sense that the number of respondents, who do not suffer from back pain, decreases with their increasing physical passivity. Conclusions: In general, we can say that both groups of girls and boys with a daily physical activity rate of up to 20% exhibit increased back pain, but not significant statistically. Within the entire surveyed group there is a demonstrable statistical dependence between the rate of daily physical activity and back pain. ER
