dc.description.abstractPhysical activity during childhood and adolescence is essential for healthy development, yet levels of activity tend to decline with age and may differ according to gender and body mass index (BMI). This study aimed to assess physical activity (PA) and sedentary behavior in children and adolescents aged 6 to 17 years and to examine differences by gender, age, and BMI. A total of 89 schoolchildren (46 boys and 43 girls) from Bizkaia, Spain, wore ActiGraph WGT3X-BT accelerometers for seven consecutive days. PA levels were categorized into light, moderate, and vigorous intensities. Statistical analyses included Pearson correlations, t-tests, and ANOVA. The results showed a strong negative correlation between age and moderate-to-vigorous physical activity (MVPA) (r = –0.738, p < 0.001), as well as between BMI and MVPA (r = –0.445, p < 0.001). Girls accumulated more light (p < 0.001) and moderate PA (p = 0.001), while boys engaged in more vigorous PA (p = 0.002). Sedentary behavior increased significantly with age (p = 0.006), and only 38% of participants met the World Health Organization's recommendation of at least 60 minutes of MVPA per day. These findings highlight the need for tailored interventions that address age- and gender-related differences in physical activity patterns and promote healthier behaviors across the school years.en
