The Effect of Zinc Administration in Short Adolescent Mothers who Breastfeed on Zinc Level, Insulin-1 Growth Factors, and Infant Growth

Abstract

BACKGROUND: Zinc is an important nutrient for humans at all stages of life, whose needs increase during pregnancy and lactation. Zinc concentrations in breast milk are considered adequate for the first 6 months of life, despite an increase in the volume of milk consumed, zinc in breast milk is likely to be sufficient if there is no diet. weaning (9). Zinc levels in breast milk cannot compensate for the increased zinc requirements of the premature neonate due to higher than normal zinc requirements, small liver size with reduced zinc stores and a shortened digestive system. AIM:This study aims to measure serum zinc levels, IGF-1, and growth of infants aged 6 months in short adolescent mothers who are breastfeeding and have been intervened with zinc supplementation. MATERIAL AND METHOD: This study is a quantitative study using a quasi-experimental design, and a pretest-posttest approach with a control group. The sampling technique used purposive sampling with inclusion criteria, namely: infants from breastfeeding mothers aged <19 years, history of SEZ, maternal height <150 cm, so that the total sample size was 60 respondents (30 control samples and 30 intervention samples). Analysis of the data collected in the study was processed analytically with the Independent Sample T-Test and Paired T-Test tests. RESULT: From this study, it was found that the Paired Sample T Test results obtained p value < 0.001 indicating that there was a difference before and after the intervention, so it can be concluded that there was an effect of giving zinc supplementation on serum zinc and IGF-1 levels of infants in the intervention group. And through the Independent T test, the value of p = 0.001 < = 0.05. This shows that there is an effect of zinc supplementation on serum zinc and IGF-1 levels in infants. While the results of the Z-Score test for body weight and Z-Score values for body length obtained p <0.001. This illustrates that there is a difference between the intervention group and the control group, so it can be concluded that there is an effect of zinc supplementation on the growth of infants aged 6 months. CONCLUSSION: There was a significant difference between before and after the intervention in the two groups, so that zinc supplementation was effective in influencing serum zinc levels, IGF-1 and infant growth.
