<bold>Purpose.</bold> The purpose of this study was to determine relationships between the somatic build and motor abilities of children and adolescents from Jedlina-Zdrój and objective quality of life of their families. <bold>Basic procedures.</bold> 524 children aged 8 to 16 years were examined. Body height, body mass and three skinfold thickness measurements were taken as well as BMI and LBM were calculated. The subjects performed the following fitness tests: plate tapping, 10 × 5 m shuttle run, standing broad jump, sit-ups, 1 kg medicine ball throw and sit and reach. Maximum anaerobic power (MAP) was calculated. The study was completed with a survey questionnaire of parents on quality of life of their families. <bold>Main findings.</bold> Mean values of somatic parameters in boys examined represent an increasing gradient in relation to increasing objective quality of life. In girls the social-economic status of their families affected only their body height and body mass. In boys the average values of locomotive speed, lower limb explosive strength and maximum anaerobic ability test results increase along with improving social-economic status of their families. In girls the objective quality of life has a significant impact only on the upper limb movement speed. <bold>Conclusions.</bold> The objective quality of life differentiates the somatic growth of children examined. The social-economic status of children's families affects subjects' motor ability, but the correlations are lower and more multidirectional than in the case of somatic parameters.
