Abstract: Objective To explore the 0~2 years old physical growth trend change of small for gestational age infant (SGA) from 2000 to 2009. Methods The SGA from 2000 to 2009 in child health care of West China Second University Hospital were reviewed retrospectively.The physical growth were measured at 3,6,12,18,24 months.The velocity of growth was measured by Z score,and the deviation of growth were analyzed. Results There were 240 male SGA cases and 352 female SGA cases whose birth data were complete and accurate.The incidence of growth retardation of male at 3,12,18 months were significantly higher than those of female,but the incidence of overweight of female at 3 months were significantly higher than that of male(P<0.05),No matter male SGA,female SGA,the length and growth rates of SGA born in 2000-2004 at 3,6,12,18 months old were significantly less than those born in 2005-2009(P<0.05),moreover,the incidence of catch-up in length at different age were significantly less than those born in 2005-2009 in male(P<0.05).The incidence of catch-up in length at 3,6,12 months old were significantly less than those born in 2005-2009 in female(P<0.05).The level,growth rate,incidence of catch-up of weight had no differences among different groups. Conclusions The SGA was retarded in its growth and development influenced by unhealthy factors during fetal life.SGA usually catched up in growth at 3~6 months.The child health care workers should pay attention to the key of health care according to the different age.
