Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the increase in the concentration of retinol in breast milk, verified by the high performance liquid chromatography method, based on a variation of at least 0.3 micromol / L (80% power and 95% confidence) between the four groups at the end of the follow-up.;There was a change in the concentration of retinol in breast milk using the high-performance liquid chromatography method, based on the finding that the maximum increase among treatment groups was 0.16 micromol / L at the end of follow-up | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate the biochemical (serum) nutritional status of maternal vitamin A at the beginning of the study, using the high-performance liquid chromatography method, based on the fact that serum retinol levels below 0.7 micromol / L maternal vitamin A.;At the beginning of the study, using the high-performance liquid chromatography method, it was found that, when the nutritional state of vitamin A was evaluated from the general retinol mean in the population, it was adequate (1.24 micromol / L). Vitamin A deficiency was observed in 21.5% of the women, since they had retinol concentrations lower than 0.7 micromol / L in the serum.;To assess the biochemical nutritional status (umbilical cord serum) of the baby's vitamin A at the start of the study using the high-performance liquid chromatography method, based on the fact that serum retinol levels below 0.7 micromol / L have configured status mismatch.;At the beginning of the study, using the high-performance liquid chromatography method, it was found that when the nutritional state of vitamin A was evaluated from the general retinol mean in the infant population, it was adequate (0.77 micromol / L). The low vitamin A status was found in 41.5% of the babies, since they had retinol concentrations below 0.7 micromol / L in the umbilical cord serum. | — |
