effects of motor development stimulation on anthropometric indices of infants aged 1-12 months in foster care homes

background: the first three years of life have a pivotal role in growth and development of infants. extra-uterine environment largely affects brain development of infants during the first year of life.however,no specific programs are available for brain development stimulation in foster homes. aim: this study aimed to evaluate the effects of motor development stimulation package on anthropometric indices of infants staying in foster homes. method: this experimental study was conducted on 50 infants aged 1-12 months at ali asghar foster home of mashhad, iran in 2013. infants were randomly divided into two groups of intervention (n=25) and control (n=25). motor development stimulation packages were used for intervention group three times a week for eight consecutive weeks (24 sessions, two hours each). anthropometric indices of infants were evaluated using standard instruments before and after intervention. data analysis was performed in spss v.11.5 using independent t-test and mann-whitney u test. results: in this study, mean age of infants in intervention and control groups was 6.04±3.48 and 4.3±3.70 months, respectively. in total, 68% of infants were male, and 32% were female. after intervention, mann-whitney test results showed no statistically significant difference in height (p=0.47) and head circumference (p=0.11) of infants between the groups. however, independent t-test showed a statistically significant difference in body weight of infants (p=0.007) between the groups after intervention with the stimulation care package. implications for practice: according to the results of this study, use of evidence-based motor development stimulation package for eight weeks resulted in increased weight of infants, while it had no effect on height and head circumference. therefore, it is recommended that complementary studies be conducted in this regard.
