BACKGROUND: This study aimed to compare the effects of adjustable fortification (AF), targeted fortification (TF), and standard fortification (SF) methods on the early growth of very low birth weight infants. MATERIALS AND METHODS:Sixty infants <32 weeks of gestational age and weighing <1,500 g were selected. These infants were exclusively fed with breast milk and were randomized into three fortification groups: SF, AF, and TF. SF consists of adding a fixed amount of fortifier to maternal milk. Blood urea nitrogen levels are used to adjust fortifier in AF. In TF, breast milk is analyzed and fortified accordingly based on the macronutrient content to achieve the targeted intake. RESULTS: A total of 76 preterm infants were eligible for the study. Sixty infants were randomized into three groups. At the end of the fourth week of fortification period, median daily weight gain of the infants was similar in the AF [23.5 g/(kg·d)] and TF groups [25.5 g/(kg·d)], and significantly higher in both groups than in SF group [12 g/(kg·d)] (AF versus SF group, p < 0.001 and TF versus SF group, p < 0.001). Weight, head circumference, and length were compared across the three groups regarding percentile. Significant improvement in the percentile groups of weight and head circumference was observed in the AF and TF groups. In the SF group, a significant decline in the percentile groups of weight, head circumference, and length was detected. Daily protein and energy intakes in AF and TF groups were significantly higher than those in SF group (SF versus AF, p < 0.001 and SF versus TF, p < 0.001). CONCLUSIONS: Fortifying breast milk with AF and TF methods was found to improve body weight, length, and head circumference percentiles of preterm infants, whereas SF method was found unsatisfactory. To provide optimum growth for preterm babies, breast milk that has been fortified by using AF and TF strategies should be recommended in neonatal intensive care units.
