Rationale: Recent studies have demonstrated that chil-dren born prematurely (BW < 1.5 kg) have lower bonemineral content and density compared with childrenborn at term gestation. The objective is to studythe dental mineralization of children born prematurely(PT) by analyzing calcium, phosphorus and magnesiumas biomarkers of nutritional status in these elementscomparing with a control group of children born at term(AT).Methods: A cohort of 30 children (6 8 y) PT group wasselected and primary dental mineral status was comparedwith these of 25 AT healthy children (6 9 y). A foodintake questionnaire (Mataix, 2007 software) was askedto obtain %RDA intakes of calcium, phosphorus andmagnesium. Calcium and magnesium content of wetmineralized samples were determined by flame atomicabsorption spectrometry, phosphorus was analyzed insame samples by colorimetric Fiske Subbarow method.Results: No significant differences were obtained incalcium, phosphorus and magnesium intakes betweengroups. PT children had lower dental calcium, phosphorusand magnesium content than AT children: 188.5±10.2.vs, 254.3±12.3, 100.4±5.6 vs 138.8±9.2 and 5.34±1.5 vs6.74±1.3 (mg/g dry theeth), respectively (p < 0.05). Nosignificant differences were found in phosphorus contentbetween two groups.Conclusion: PT group of children have lower primaryteeth calcium and magnesium content, compared with ATchildren. Mineral supplementation of the mother duringpregnancy an/or of the early diet of PT infant may beneeded, taking into account that genetic determinantsmay influence on bone mineralization of PT infants.

P307ASSESSMENT OF NUTRITIONAL STATUS AND ANEMIA ININFANTS AND PRE-SCHOOL OF A DAY CARE IN ONE CITYFROM SOUTH OF THE COUNTRYJ.L. Cardoso1, C.C.G.M. Moreira2, M.M.F.L. Lazzarotto2,G.G.K.B.

Rationale: To acess nutritional status, anemia frequencyand the association of these with family income, inenrolled in a day care in one city from south of thecountry.Methods: It is a cross-sectional study accomplished in73 children, from one to six years old; anthropometric

assessment and laboratorial determination of hemoglobinwas carried out: nutritional status determined accordingto curves of OMS, according weight for stature and massindex corporal for age in Z-score; it was consideredanemia when hemoglobin below 11 g/dl; the familyincome was appraised as per capita income in minimumwages.Results: About wheight for stature in Z-score, 91.78%of the children were classified as eutrophic, 1.37% aslow wheight for stature and 6.85% as high wheight forstature. According index of corporal mass for age, 67.12%had appropriate index; 1.37% had low index; 23.29%had overwheight and 8.22% obesity. Anemia prevalencewas 8.22%. In eutrophic children, 6.12% were anemic;in overwheight children, 17.65% were anemic. Therewere not cases of anemia in undernourished or obesechildren. Overweight or obesity were found in 32% of thechildren with family income per captures smaller thanhalf minimum wage and in 30% in the others. Of thechildren with anemia, 100% have family income less thanhalf minimum wage per capita.Conclusion: Anemia frequency in this sample is lowand it has association with low income per capita. Themain nutritional disorders found were overweight andobesity, and nutritional status doesn’t have associationwith the family income. Overweight children have higherfrequency of anemia.

P308EARLY ENTERAL FEEDING THROUGH NEEDLE CATHETERJEJUNOSTOMY IN SURGICAL NEONATESJ. Wu1, W. Cai1. 1Clinical Nutrition, Xin Hua Hospitalaffiliated to Shanghai Jiaotong University School ofMedicine, Shanghai, China

Rationale: To evaluate post-operative jejunostomy feed-ing in terms of nutritional, gastrointestinal and mechani-cal complications in neonates after upper gastrointestinalsurgery.Methods: We retrospectively collected medical records ofsurgical neonates with needle catheter jejunostomy (NCJ)performed during upper gastrointestinal operation fromJan, 2003 to Dec, 2008. Details of patient characteristics,including gestational age, birthweight, age at operation,pre- and post-operative body weight, malformation char-acteristics, surgical procedures, parenteral and enteralnutrition use, complications, and length of hospital staywere obtained.Results: A total of 38 neonates (14 girl/24 boy,13 preterm/25 full term)) with a mean birthweight of2835 g (range 1155 to 3950) were enrolled. The averageage at operation was 6 days (range 1 to 28) with a
