Abstract

The primary nutritional problem of adolescents is the triple burden of malnutrition. Factors that trigger nutritional problems in adolescents include poor eating habits, low nutritional and socioeconomic knowledge, and sedentary activities. This study aimed to analyze differences in nutrition knowledge, diet quality, and their relationship with nutritional status among rural and urban school adolescents in West Aceh. This study used a cross-sectional design, involving 312 adolescent schools in West Aceh in 2023. Data on nutritional knowledge were collected using a questionnaire filled out by the subjects themselves, intake data using 2x24-hour food recall, and anthropometric measurements such as BAZ and Percent Body Fat (PBF) using BIA scales and microtoice. Data were analyzed using Mann-Whitney and Spearman rank tests. There were significant differences in family characteristics, nutritional knowledge, and diet quality between the rural and urban school adolescents (p<0,05). There was a significant positive relationship between nutritional knowledge and diet quality and BAZ and PBF (p<0,05) only among rural school adolescents. In conclusion, family characteristics, nutritional knowledge, and diet quality differed significantly among the adolescents by region. In rural areas, nutritional knowledge and diet quality were significantly associated with BAZ and PBF. School adolescents' knowledge and diet quality remain low; therefore, nutrition education related to balanced nutrition guidelines is required.

Abstract

Nutritional problems among school-age children remain significant, mainly due to unbalanced diets and low vegetable and fruit intake. In Indonesia, 97.7% of students do not meet the recommended consumption levels, with West Java reaching 98.3%. Most nutrition education programs emphasize knowledge improvement without considering the psychological factors influencing eating behavior. The Theory of Planned Behavior (TPB), which highlights the role of intention in shaping behavior, has rarely been applied in Indonesia. This study examined the effect of TPB-based nutrition education on knowledge, attitude, subjective norm, perceived behavioral control, and intention to consume vegetables and fruits among elementary students in Bogor District. Using a quasi-experimental design with multiple random sampling, 70 fifth-grade students were divided into treatment and control groups (n=35 each). The instruments showed good validity (r-count > r-table) and reliability (Cronbach’s alpha > 0.7). The results indicated significant improvements in all TPB constructs (p < 0.05), except for subjective norm in the control group, with higher Cohen’s d values in the treatment group. TPB-based nutrition education effectively enhanced students’ intentions and behaviors toward consuming fruits and vegetables. Further research should consider longer interventions, follow-up evaluations, and the inclusion of additional influencing factors.
