Abstract

Iron deficiency anemia remains a major nutritional problem among adolescent girls, caused by low dietary iron intake and monthly menstrual blood loss. To prevent anemia, the Indonesian government has implemented a weekly iron supplementation program (Tablet Tambah Darah, TTD) for school-aged girls since 2014. However, adherence to TTD remains low, limiting program effectiveness. Adherence is influenced by students’ attitudes, support from parents or teachers, and perceived behavioral control. This study aimed to examine the relationship between attitudes, subjective norms, and perceived behavioral control with TTD adherence among adolescent girls. A cross-sectional study was conducted at SMP Kartika II-2 Bandar Lampung, including the total population of seventh- and eighth-grade female students (n = 73). The dependent variable was TTD adherence, measured using the Morisky Medication Adherence Scale-8 (MMAS-8), while independent variables included attitude, subjective norms, and perceived behavioral control. Data were analyzed using the chi-square test. Results showed that 65.8% of students were non-adherent to TTD. Significant associations were found between attitude (p = 0.044; OR = 1.8), subjective norms (p = 0.010; OR = 2.3), and perceived behavioral control (p = 0.000; OR = 3.6) with adherence. It is recommended that schools, through teachers and school health staff, implement a structured weekly TTD schedule and enhance supervision to improve adherence among students

Abstract

Iron deficiency anemia remains a nutritional problem among adolescent girls, due to low iron intake from daily food and monthly blood loss due to menstruation. To prevent anemia, the Indonesian government has implemented an iron supplementation program through weekly iron supplementation tablets (TTD) for female students since 2014. However, compliance with iron supplementation remains low due to low intention, thus suboptimal program effectiveness. Intention to consume iron supplementation is influenced by adolescents' attitudes, subjective norms, and behavioral control. This study aims to determine the relationship between attitudes, subjective norms, and behavioral control with iron supplementation intention in adolescent girls. This study used a cross-sectional approach at SMP Negeri 14 Bandar Lampung. Respondents were 224 female students in grades VII, VIII, and IX, with a sample size determined using the Slovin formula and drawn using stratified random sampling. The dependent variable was intention to consume iron supplementation, while the independent variables were attitude, subjective norms, and behavioral control. Data were analyzed using the chi-square test. The results showed that 51.3% of female students had a strong intention to drink iron tablets. There was a significant relationship between attitude (p = 0.000; OR = 3.1), subjective norm (p = 0.015; OR = 2.2) and students' intention to drink iron tablets. Furthermore, there was no significant relationship between behavioral control (p = 0.077) and students' intention to drink iron tablets. It is recommended that schools, through teachers and school health workers, facilitate the provision of iron tablets in sufficient quantities and increase supervision during joint iron tablet drinking activities at school.
