Predicting of Motor Development in 9- 12 Month Old Infant Using Maternal Characteristics

The aim of present study was anticipation motor development of 9- 12-month-old infants. The study was a descriptive- survey. To do this research 856 infants were evaluated. In the present study, the predictor variables included maternal demographic factors (maternal mental health, type of delivery, maternal age at delivery, body mass index and maternal physical activity), and variables of motor performance (gross and fine movements), The applied measures to evaluate predictor variables included biography questionnaire (maternal age at delivery, maternal height of maternal type of delivery), Beak's habitual physical activity questionnaire, General Health Questionnaire,. And the A.S.Q screening scale was used to evaluate dependent variables. The related data were analyzed by independent T, MANOA and step by step regression. Result show body mass index anticipated 0.01 of gross milestone. In gross milestone vaginal delivery was significant. None of variables did not anticipate fine milestone in 3–8-month-old. Also, there was not any difference between vagina delivery and cesarean delivery. Weight of mother in pre-pregnancy can anticipated 0.02 gross milestone in 9–12-month-old. None of variable did not anticipate fine milestone in 9–12-month-old. There was not any difference between vagina delivery and cesarean delivery. The results show that the higher maternal BMI before and during pregnancy decreases the motor development of the child. And also, the natural delivery due to the production of beta-endorphin has a positive effect on the motor development of children.
