Objective To investigate nutrition status of low birth weight infants (LBWI) with different gestational ages,and to provide theoretical evidence for rational nutrition intervention. Methods LBWI with different gestational ages who were treated in Fujian Provincial Hospital were selected as research participants.After nutrition intervention,their blood biochemical indexes were observed and the time of enteral nutrition reaching DRIs was recorded. Results According to different gestational ages,participants were divided into 3 groups,group Ⅰ (gestational age 28~31 weeks),group Ⅱ(gestational age 32~36 weeks),group Ⅲ(gestational age 37~42 weeks).Compared with group Ⅰ,the time for enteral nutrition reaching DRIs were significantly shortened in group Ⅱ and group Ⅲ (P<0.05).The differences of the time for enteral nutrition reaching DRIs in group Ⅱ and group Ⅲ were not statistically significant (P>0.05).In terms of 1 d biochemical index,ALB in group Ⅱ and group Ⅲ significantly increased than group Ⅰ (P<0.05);Compared with group Ⅲ,TC in group Ⅰ and group Ⅱ obviously decreased,and HDL-C,LDL-C and ApoB in group Ⅰ and group Ⅱ all obviously increased with significant differences (P<0.05).In terms of the 1 d biochemical index after enteral nutrition reaching DRIs,GLu in group Ⅱ and group Ⅲ significantly increased than that in group Ⅰ (P<0.05);Compared with group Ⅱ,ALB,TC,TG in group Ⅰ and group Ⅲ all obviously decreased,HDL-C,LDL-C and ApoA all obviously increased,and the difference was statistically significant (P<0.05). Conclusion Blood lipid level detection should be conducted in low birth weight infants with different gestational ages,and reasonable nutritional intervention is suggested to adopt according to early evaluation Results .
