The study aimed to determine the effect of malunggay supplementation on the nutritional status of school children aged 7-9 years old. The study attempted to identify the impact of malunggay supplementation specifically on anthropometric measurements such as height, weight and body mass index as well as on the biochemical measurements such as hemoglobin, serum vitamin A and urinary calcium.


An approval letter was obtained from the School Division, Department of Education, Manila as well as clearance from the ethical and technical review board of the University of the Philippines, Manila. The pretest-posttest control group design was used wherein the subjects were randomly assigned to experimental group, who received the intervention and control group, who receive the placebo. Both groups were pretested before the supplementation and after the intervention period for the determination of anthropometric and biochemical measurements. The experimental group was given a test food with 1.25 grams of malunggay, while the control group received the same test food without the addition of malunggay. The test food was given during the mid-morning break for five school days per week and lasted for twelve weeks. A total of 34 subjects were included in the study, but only 31 completed the supplementation period. There were 3 dropouts for both groups, 1 in the experimental group and 2 in the control group. The nutrient composition of dried malunggay leaves was analyzed. Height and weight was measured using the standard techniques. Baseline and endline blood and urine samples were collected and were analyzed at the laboratory simultaneously at the end of the study. A 3-day food record was completed at the beginning and at the end of the study. Baseline and endline comparison of the mean and median between groups was done using T-test, Mann-Whitney U test and Wilcoxon-Signed Rank test and were analyzed using SPSS version 9 .0.


Significant increase in urinary calcium was reported in experimental group from baseline to endline. There was also an increasing trend from baseline to endline with serum vitamin A and anthropometric measurements.


Malunggay supplementation increased calcium intake of children as estimated by urinary calcium, but no significant results were obtained from weight, height, hemoglobin, and serum vitamin A.
