Vitamin D and Magnesium Intakes in Adolescents Have Not Met Recommended Nutritional Requirement

Abstract

Adolescence is characterized by rapid physical growth and development, resulting in increased nutritional requirements, particularly micronutrients. Vitamin D and Magnesium are micronutrients required by the body. Vitamin D deficiency is closely associated with magnesium deficiency in the body. The aim of this study was to identify the levels of vitamin D and magnesium intakes among adolescents. This study employed an analytical observational method with a cross-sectional approach. It was conducted at State Junior High School 1 Kuta and State Junior High School 4 Kuta Selatan. The research subjects consisted of adolescents aged 13–15 years from three selected classes in each school. The data were collected using anthropometric measurements and interviews using the SQ-FFQ. The Mann-Whitney test was used to analyze differences in magnesium and vitamin D intakes between adolescents with overweight and normal nutritional status. The study found that micronutrient intakes in overweight and normal adolescents did not meet the RDA standards. The analysis revealed significant differences in vitamin D intake (p<0.001) and magnesium intake (p<0.00) between overweight adolescents and those with normal nutritional status. Vitamin D intake among adolescents with normal nutritional status (1.1 mcg/day) and those with overweight adolescents (2.2 mcg/day) was still below the recommended RDA limit. Magnesium intake among adolescents with normal nutritional status (87.6 mg/day) and overweight adolescents (189 mg/day) remains below the recommended RDA threshold. Given the low levels of vitamin D and magnesium intakes compared to the RDA recommendations, it is important to improve the quality of dietary patterns, particularly in terms of micronutrient intake.
