Abstract

Background and aim

High risk newborns are often much smaller than healthy infants when are discharged from hospital. Different types of feeding: breastmilk, formula or mixed can influence growth rates and improve development.

Background and aim

The aims of the study were to evaluate the growth rates; catch–up rate and some biological parameters of the nutritional status such as: hemoglobine, iron, calcium, phosphor, magnesium, the level of plasmatic protein, nitrogen balance at differents ages : 1-2-4-6 months in three different types of nutrition – breastmilk, special formula for premature, breastmilk with premature formula or started formula.

Material and methods

A retrospective study was performed in a tertiary neonatal care unit between 2011–2013 in the County Hospital of Cluj, Romania on 383 infants presented to periodical examination in the follow-up program: 465 records. We divided into 3 categories : group I-VG≤32 weeks, group II-VG between 32–36 weeks and group III-VG≥36 weeks of gestation. The evaluation consultations were performed at 1-2-3-4-5-6 months.

Material and methods

Each evaluation consisted of determining: weight, CBC, calcium, iron, magnesium, protein, Blood Urea Nitrogen (BUN) levels.

Informed consent was obtained

Statistical analysis was made with Microsoft Excel 2016 and IBM SPSS v.23.

Results

Growth rate up to 6 months wasn ‘t significantly influenced by the type of feeding (p=0.319).

Results

Hemoglobine at 2 months highlighted statistically higher values in formula fed group: 11.77±2.07g compare with premature formula fed group:10.848±1,7556g(p=0.008).

Results

The values of iron at 2 months hasn’t presented any significant differences according to the types of feeding (p=0.475). There is a significant decrease of iron levels that occurs gradually with age in the breastfed ones, r=−0.89.

Results

Different calcium levels were registered according to types of feeding (p=0.003) until 6 months.

Results

Magnesemia were not influenced by feeding type at any groups.

Results

BUN in group I was significantly smaller in breastfed compared with premature formula fed infants(p=0.000) at 2 months. Up to 6 months the value is significantly lowered in cases of breastfed, p=0.001.

Results

The values of the protein in≤32 weeks is directly influenced by the type of feeding p=0.024.

Results

Protein levels is significantly influenced in group II(p=0.026).

Results

Phosphatemia is significantly influenced by the type of feeding in group II(p=0.043).

ConclutionS

Increase in bodyweight of newborns under 32 SS isn’t influenced significantly by the type of feeding up to 6 months.

ConclutionS

Calcium registered significantly different values under the different types of feeding in the prematures≤32 weeks of gestation in the first 6 months of life.

ConclutionS

Phosphoremia is significantly influenced by the type of feeding in the second group.

ConclutionS

Iron drops significantly with age in breastfedgroup.

ConclutionS

The level of protein in group I is directly influenced by the type of feeding.

ConclutionS

At 2 months of age BUN is significantly influenced by the type of feeding in the first group.
