THE HEALTH BELIEF MODEL COMBINED WITH EDUCATION ON HEALTHY FOOD PREPARATION TO IMPROVE DIETARY IRON INTAKE AMONG ADOLESCENT GIRLS
Anemia is still a public health problem among adolescent girls in low and middle-income countries (LMICs), and nutrition education is needed to improve their iron intake. Therefore, this study aims to measure the effects of nutrition education based on HBM combined with training about healthy food preparation to improve dietary iron intake among adolescent girls in boarding schools. This research was a pre test post test control group design. The intervention group (IG) consists of two boarding schools, forty adolescent girls, and six cooks, while the control group (CG) contains four boarding schools, forty adolescent girls, and ten cooks. Nutrition education based on HBM combined with training about healthy food preparation was held for the IG with follows-ups 4 and 12 weeks after the intervention. After the process, data were collected from both groups and analyzed using an independent t-test and Mann Whitney. The dietary intake of energy, protein, and iron, namely 1421.1 kcal ±363.7-1543.4 kcal ±28.5, 32.3 g ±8.6-49.7 g ±6.7, and 7.8 mg-12.1 mg±2.0, respectively, increased at follow-up 1 in the IG. The results showed that there were differences in the dietary energy, protein, and iron intake both groups at follow-ups 1 and 2 (p<0.05). These findings indicate that HBM strategies combined with education about healthy food preparation can improve dietary iron intake among adolescent girls in boarding schools. Therefore, the authority can consider using this pattern to design and perform educational interventions to increase iron consumption.
