Abstract

Anemia remains a major public health problem among adolescent girls in Indonesia. The effectiveness of iron supplementation programs is often constrained by inadequate knowledge and poor adherence to iron tablet consumption. This study analyzed the effects of iron supplementation integrated with nutrition education on knowledge, adherence, and hemoglobin (Hb) levels among adolescent girls. A quasi-experimental pretest-posttest control group design was conducted among 56 adolescent girls from four senior high schools in Maros Regency, Indonesia, using multistage cluster random sampling, with two schools allocated to an intervention group (n = 27, iron supplementation plus nutrition education) and two schools to a control group (n = 29, iron supplementation only). Baseline knowledge scores did not differ significantly between groups (p = 0.115); adherence was not assessed at baseline, as it was a prospective outcome measured throughout the intervention using the DOS method. Data were analyzed using the Wilcoxon, Mann-Whitney, paired t-test, and ANCOVA, with baseline hemoglobin, dietary intake, nutritional status, and menstrual cycle as covariates. Knowledge increased significantly in the intervention group (p < 0.001), with significant between-group differences in knowledge (p < 0.001) and adherence (92.6% vs. 44.8%; p = 0.002). Mean Hb rose significantly in the intervention group, from 13.12 ± 1.78 to 14.15 ± 1.35 g/dL (p = 0.011). Adjusted Hb remained significantly higher in the intervention than control (13.86 vs. 12.90 g/dL; F = 6.065; p = 0.017). Integrating nutrition education into iron supplementation programs improved knowledge, adherence, and Hb levels, supporting incorporation into school-based anemia prevention efforts.

Abstract

Anaemia remains a severe public health problem affecting adolescent girls. Despite government-provided Iron and Folic Acid (IFA) supplementation, adherence remains low due to unpleasant taste and odour. To analyse the impact of blood-boosting tablet (IFA) intervention accompanied by orange fruit on liking levels, consumption adherence, and haemoglobin levels among adolescent girls. This quasi-experimental non-equivalent control group pre-test-post-test design involved 56 adolescent girls from four schools in Maros Regency, Indonesia. Participants were allocated by cluster into an intervention group (n=27) and a control group (n=29), without individual randomization. The intervention group received IFA tablets with 100–150 g of orange fruit once weekly for four weeks, while the control group received IFA tablets alone. Taste and aroma liking were assessed using a 5-point hedonic scale, and adherence was monitored using Directly Observed Supplementation (DOS). Haemoglobin levels were measured at pre-test and post-test. Liking and adherence were analysed using the Mann–Whitney U test, while post-test haemoglobin was analysed using ANCOVA adjusted for covariates. He intervention group had higher mean ranks for taste liking (35.15 vs. 22.31; p=0.001), aroma liking (32.78 vs. 24.52; p=0.044), and adherence (35.06 vs. 22.40; p=0.002) than the control group. After covariate adjustment, study group was associated with post-test Hb (p=0.005; partial η²=0.159). IFA supplementation with orange fruit showed better outcomes in terms of liking, adherence, and haemoglobin levels compared with IFA supplementation alone. However, these findings cannot yet establish a causal relationship due to the non-randomized study design, short intervention duration, and limitations related to cluster-level allocation.

Abstract

Background: Low body weight (underweight) in toddlers remains a nutritional challenge in Indonesia, with a national prevalence reaching 16.9% in 2024. Local food-based Supplementary Feeding (PMT) is one of the government-recommended nutrition intervention strategies to address this problem in an affordable and sustainable manner. Objective: This study aimed to determine the effect of local PMT in the form of chicken nuggets enriched with egg and vegetables on changes in body weight among underweight and at-risk-of-underweight toddlers in the working area of UPTD Puskesmas Topoyo in 2025. Methods: This study used a pre-experimental design with a one-group pretest-posttest. The sample consisted of 35 underweight toddlers who received local PMT for 28 days. Data were analyzed using the Wilcoxon Signed Rank Test to examine differences in body weight before and after the intervention, and the Mann-Whitney U test to analyze the relationship between PMT consumption compliance and the magnitude of weight gain. Results: Mean body weight increased from 9.2 kg (SD=2.1) to 9.8 kg (SD=2.2) after 28 days of intervention, with a mean increase of 0.6 kg (SD=0.6). The Wilcoxon test showed a significant difference between body weight before and after PMT administration (p=0.000). A total of 85.7% of toddlers were classified as compliant in consuming PMT (≥75%), but no significant difference in weight gain was found between compliant and non-compliant toddlers (p=0.536). Conclusion: Local PMT had a significant effect on increasing the body weight of underweight and at-risk-of-underweight toddlers within a 28-day period, so it can be considered as a routine nutrition intervention program at the community health center, while still taking into account the need for a longer intervention duration to achieve a comprehensive improvement in nutritional status.
