The levels of physical activity (PA) and sedentary behaviour are significant indicators of health behaviour and their monitoring is crucial in developing public policy in the area of health promotion and non-communicable disease prevention. The aim of the study was to describe the prevalence of PA and sedentary behaviour as well as age and gender differences in Czech adults (18–90 years old, N = 1753; 48.4% male) participating in the Global Physical Activity Questionnaire (GPAQ) cross-sectional study 2011. To assess the significant differences between self-reported PA and sedentary behaviour the MANOVA, a post hoc Fischer's least significant difference (LSD) test and logistic regression were used. The level of PA was classified according to the amount of MET-minutes per week as high, moderate or low. Irrespective of age and gender, 32.3% of adults reported a low level of PA; 21.3% of adults fell within the category of moderate level of PA and 46.4% of adults reported a high level of PA. The level of PA decreases with age; men are generally more physically active than women. More than 60% of adults across all age categories are assessed as ‘sedentary’. The highest rate of sedentary behaviour was observed in adults over 65 years of age. The development of national strategies for PA promotion together with the development and verification of specific intervention programmes, especially for women, should be a priority in the Czech Republic.
This study examines trends in overweight and obesity, physical activity (PA) and screen time (ST) among Czech adolescents over a recent 12-year study period. Nationally representative samples consisted of 19,940 adolescents (9760 boys and 10,180 girls) aged 10.5–16.5 years from the Czech Health Behaviour in School-aged Children (HBSC) questionnaire-based surveys conducted in 2002, 2006, 2010 and 2014. Trends in the prevalence of overweight/obesity, meeting the recommendations for moderate-to-vigorous PA (MVPA) (≥60 min per day of MVPA) and excessive ST (>2 h per day) were estimated using logistic regression. Significant increases (p < 0.001) in the prevalence of overweight/obesity between the years 2002 and 2014 were evident for both adolescent boys (18.3%2002–24.8%2014) and girls (8.3%2002–11.9%2014). Compared to 2002, in 2014 significant decreases (p < 0.001) in meeting MVPA recommendations were observed among boys (32.2%2002–25.6%2014) and girls (23.2%2002–19.2%2014). Moreover, in boys we observed significant increases (p < 0.001) in excessive ST on weekdays (75.1%2002–88.8%2014), as well as on weekends (78.3%2002–91.9%2014) between the years 2002 and 2014. Increases in overweight/obesity with concomitant decreases in PA provide evidence in support of the current and upcoming efforts of government and commercial organizations in implementing interventions aimed at reducing excessive body weight among Czech adolescents.
This study demonstrated that AC to school decreased sharply among Czech children of school age from 2006 to 2014. However, walking was the most frequently used mode of travel. The boys were significantly more likely to cycle to school compared to the girls. PA interventions for youth should encourage participation in AC to school in the Czech Republic.
BackgroundThis study examined a) trends in overweight/obesity, moderate-to-vigorous physical activity (MVPA), and screen time (ST) among Czech adolescents over a 12-year study period (2002–2014) in relation to family affluence (FA) and b) correlates of adolescent overweight/obesity from different FA categories.MethodsA nationally representative sample of 18,250 adolescents (51.4% girls) aged 10.5–16.5 years was drawn from the Czech Health Behaviour in School-aged Children questionnaire-based surveys in 2002, 2006, 2010, and 2014. Using the FA scale, the socioeconomic status (SES) of the respondents’ families was assessed. SES-stratified trends in the prevalence of overweight/obesity meeting the MVPA (≥60 min/day), and ST (≤2 h/day) recommendations were assessed using logistic regression.ResultsA trend-related significant increase (p < 0.05) in the prevalence of overweight/obesity was observed in low−/medium-FA boys and medium−/high-FA girls. Unlike in high-FA adolescents, a significant decrease was revealed in the rates of meeting the MVPA recommendation in low-FA boys (28.9%2002 → 23.3%2014, OR = 0.75, 95% CI = 0.59–0.95, p < 0.05) and girls (22.3%2002 → 17.3%2014, OR = 0.73, 95% CI = 0.57–0.92, p < 0.01). A significant (p < 0.001) trend-related increase in excessive ST was evident in adolescents regardless of gender and FA category. Generally, girls and older adolescents had lower odds of overweight/obesity than boys and 11-year-old adolescents. While in the high-FA category of adolescents, achieving 60 min of MVPA daily and the absence of excessive ST on weekdays significantly (p < 0.01) reduced their odds of being overweight/obese, in low-FA adolescents this was not the case.ConclusionsHigh rates of overweight/obesity and a poor level of daily MVPA among low-FA children provide disturbing evidence highlighting the necessity of public health efforts to implement obesity reduction interventions for this disadvantaged population.
BackgroundThe aim of this study is to explore the association between family-related factors and excessive time spent on screen-based activities among school-aged children.MethodsA cross-sectional survey using the methodology of the Health Behaviour in School-aged Children study was performed in 2013, with data collected from Slovak (n = 258) and Czech (n = 406) 11- and 15-year-old children. The effects of age, gender, availability of a TV or computer in the bedroom, parental rules on time spent watching TV or working on a computer, parental rules on the content of TV programmes and computer work and watching TV together with parents on excessive time spent with screen-based activities were explored using logistic regression models.ResultsTwo-thirds of respondents watch TV or play computer games at least two hours a day. Older children have a 1.80-times higher chance of excessive TV watching (CI: 1.30-2.51) and a 3.91-times higher chance of excessive computer use (CI: 2.82-5.43) in comparison with younger children. More than half of children have a TV (53%) and a computer (73%) available in their bedroom, which increases the chance of excessive TV watching by 1.59 times (CI: 1.17-2.16) and of computer use by 2.25 times (CI: 1.59-3.20). More than half of parents rarely or never apply rules on the length of TV watching (64%) or time spent on computer work (56%), and their children have a 1.76-times higher chance of excessive TV watching (CI: 1.26-2.46) and a 1.50-times greater chance of excessive computer use (CI: 1.07-2.08). A quarter of children reported that they are used to watching TV together with their parents every day, and these have a 1.84-times higher chance of excessive TV watching (1.25-2.70).ConclusionsReducing time spent watching TV by applying parental rules or a parental role model might help prevent excessive time spent on screen-based activities.
