Zinc Deficiency among Adolescence in Stunting Locus Area, Lombok, Indonesia

Abstract

Adolescence is at risk for zinc deficiency due to their high acceleration of growth, with bone mineral deposition reaching 80-90% by the adolescent phase. In zinc deficiency, adjustments in zinc pools were made, including the release of zinc retention in bones. Severe zinc deficiency could lead to growth retardation. This study aimed to determine the occurrence of zinc deficiency in the early adolescent stage (10 -12 years) in the stunting locus area, Lombok. In the first stage, a cross-sectional design was conducted among children aged 10 -12 years in Mataram City and East Lombok. In the second stage, subjects were assigned to the stunting and non-stunting group with a case-control design. Zinc intake assessment of 3-day 24 hours recall and concentration of zinc serum were used to determine zinc status. Approximately 34% of the subjects were stunting (n=774). Further analysis showed that 100% of the subjects (n=207) had a low zinc intake, with the average zinc intake below 45% of the recommended dietary allowance for zinc. The occurrence of zinc deficiency according to zinc serum concentration was only 2% of subjects. No significant difference in zinc intake and zinc serum was found between the stunted and non-stunted groups. Low zinc intake was observed among children in stunting locus districts. However, the proportion of zinc deficiency based on zinc serum concentration was very small. Zinc serum concentration may not capture zinc deficiency in the population, especially the mild or moderate ones.

Determinan dan Faktor Risiko Stunting pada Remaja di Indonesia : Literature Review

“…Hasil penelitian ini sejalan dengan penelitian di Palestina yang menemukan bahwa zink berpengaruh terhadap kejadian stunting, remaja yang mengalami defisiensi zink memiliki risiko lebih besar terkena stunting dibanding remaja yang memiliki asupan zink normal (AbuNada et al, 2013). Penelitian yang dilakukan di Lombok menunjukkan bahwa remaja yang mengalami stunting mengkonsumsi zink kurang dari asupan zink yang dianjurkan (Irawati et al, 2022). Namun demikian, hasil yang berbeda ditemukan pada penelitian Irawati di Lombok yang menemukan bahwa tidak ada perbedaan asupan zink pada kelompok remaja stunting dan yang tidak stunting (Irawati et al, 2022).…”
