The aim was to investigate the association between parental education level and physical activity (PA) in pregnancy with offspring’s physical fitness (PF) and obesity status in childhood considered several covariates. Population-based data were obtained from a national database that included anthropometric and PF (cardiorespiratory fitness, speed, and body strength) data of almost all Greek children 8 to 9 years. Α random sample of 5,125 dyads of mothers-children was evaluated. Telephone interviews were carried out with the use of a standardized questionnaire for the collection of maternal lifestyle factors. Children whose mothers had secondary/tertiary educational levels had higher odds of overweight/obesity by 30% in boys and 44% in girls and increased odds for low performances in CRF and upper body explosive strength tests, in boys (OR=1.73, 95%CI: 1.24-1.43 and OR=1.29, 95%CI: 1.07-1.72, respectively) and girls (OR=1.62, 95%CI: 1.15-2.27 and OR=1.73, 95%CI: 1.23-2.25, respectively) than their peers with mothers of basic educational level. Maternal PA levels in pregnancy did not found to significantly associate either to child’s obesity status neither to PF. Considerable variation in BMI and PF status in association with maternal education has been demonstrated, but no association was found for PA in pregnancy.
