Do infants using baby walkers suffer developmental delays in acquisition of motor skills

Development is a complex process, completed over a specific period of time, through the maturation of the nervous system. It is affected by genetic, ethnic,nutritional, social, and economic factors; one of the environmental factors affecting the acquisition of motor skills in infants is the use of baby walkers. Since this device is very commonly used for infants in our country, we conducted this study to evaluate its effects on the acquisition of motor skills in this age group of children.This longitudinal study was conducted in 2005 on 300 infants referring to the Primary Health Care Centers of Kashan district in 1384; the infants were divided into two groups of 150 babies each, with the case group using baby walkers, while the other 150, the controls, did not. All babies were followed for two years, and the ages for acquisition of motor skills were documented during face-to face or telephone interviews with the parents. Data were analyzed using the T-test and the Chi Square test.Of the study population, 175 babies (58.33%) were male. The mean age of acquisition of motor skills including rolling, crawling, moving on hands and feet, sitting without and with help, standing and walking dependently and independently were found to be delayed in infants using baby walkers, a difference between the two groups of walker users and non- walker users that was statistically significant (P<0.001).Considering the adverse effects that walkers have on the acquisition of motor skills in infants, as demonstrated by the results of this study, we do not recommend the use of baby walkers in infants.
