[Effects of touch on growth and mentality development in normal infants].
OBJECTIVE
To determine the effects of conducting Touch to infants upon their growth and mental development, sleeping and disease conditions, as well as the difference of effects of conducting Touch among infants of different month age.


METHODS
310 normal full-term infants aged 0-6 months were divided randomly into Touch group (n = 208) and control group (n = 102). Parents of Touch group were asked to conduct Touch to their infants 2-3 times/day, lasting 15-20 minutes every time, for at least 3 months. Intelligence tests were performed to infants of both groups at the beginning of the experiment and 6 months later (CDCC measurement table was employed). Data such as height, weight, circumferences of head and chest, sleeping, feeding and disease conditions etc. were recorded each month in a successive period of 6 months. Statistical analysis was conducted using SPSS 10.0.


RESULTS
(1) The average score of mental development (MDI) was 7.4 higher, with a statistically significant difference, among the infants who began to receive touch within 3 months after birth than those infants with the same age in control group. The average score of psychomotor development index (PDI) was 5.8 higher, with a statistically significant difference, among the infants who began to receive touch within 3 months after birth than those infants with the same age in control group. Infants who began to receive touch within 3 months after birth slept remarkably better than those in control group did. No significant difference was found in scores of MDI and PDI and sleeping condition between infants who began to receive touch 3 months after birth and the infants with the same age in the control group. (2) Weight gain and growth in chest circumference in infants receiving touch within one month after birth were significantly better compared with the infants of the same age in the control group. There was no significant difference in values of height and head circumference between the two groups. There was no significant difference in values of height and head circumference between the two groups. (3) No significant difference in the incidence rates of acute respiratory infection and diarrhea disease was found between the touch group and control group.


CONCLUSIONS
(1) Growth and mental development of infants can be improved by touch. Tthe earlier to conduct touch the better the effects. (2) Touch helps improve sleeping condition in infants.
