This study aims to compare the safety and efficacy of a new HMF and those of other HMF used before in very preterm infants.
Infants with fortified human milk feeding have the same rate of growth, lower incidence of nosocomial infections and feeding intolerance compared to those with formula feeding during hospitalization. However, the currently human milk fortifiers (HMF) have some nutritional components defects to meet the needs of very preterm infants. New HMF provide higher protein and fat, which are safe and well tolerate to use in preterm infants. Study on safety and efficacy of the new HMF is insufficient in Chinese preterm infant population. Our aims are to compare the safety and efficacy of a new HMF and other HMF used before in very preterm infants. Very low preterm infants with birth weights of 1000-1499g and gestational age 28+0 weeks to 31 + 6 weeks are included. Infants feeding with new HMF are in the experimental group. Infants feeding with other HMF are in the control group, a historically control group. Physical growth, nutritional indexes, incidence of feeding intolerance, and time to achieve full enteral feeding are compared between the two groups.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| The new HMF group | Experimental | Very preterm infants tolerating 80mL/kg/day of enteral feeding for >24 hours are started to receive the new human milk fortifier. Study procedure is from the first day of full-strength fortification feeding to the 21th days of that. |
|
| Other HMF group | No Intervention | This group is a historical control group using the other HMF. Infants with similar gestational age, birth weight, feeding start time and length of hospitalization are enrolled into the control group. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| A new human milk fortifier | Dietary Supplement | Contents of protein, protein/energy ratio, moderate hydrolysis of whey protein, medium-chain fatty acid are increased in the new HMF |
| Measure | Description | Time Frame |
|---|---|---|
| Growth velocity of weight | Weight is tested daily using the same electronic weighing scale in the different study units. Growth velocity of weight is described in g/day. | During the procedure |
| Measure | Description | Time Frame |
|---|---|---|
| Growth velocity of head circumference | Head circumference is measured weekly using a nonelastic measuring tape placed over the largest circumference of the skull weekly. Growth velocity is described in cm/week. | During the procedure |
