Abstract

Zinc deficiency can cause growth and health problems, whereas protein from soy sources contributes to essential nutritional intake. This study aimed to evaluate the effects of soy plus zinc (SPZ) supplementation on growth and kidney health in Wistar rats. This study used a randomized controlled trial design with 24 rats divided into five treatment groups, including a control group. SPZ supplementation was administered daily for 14 days with varying zinc doses (0.020 mg and 0.035 mg per gram of body weight) and palatability enhancement using vanilla flavoring. Data obtained through measurements of initial and final body weights and kidney weights were analyzed using ANOVA to determine significant differences between groups. The results showed that SPZ supplementation positively contributed to growth, as evidenced by a significant increase in the final weight of rats compared to their initial weight (p < 0.05). Histological analysis of the kidneys indicated no visible structural damage, and the average increase in kidney weight was approximately 26.5%. The combination of soy and zinc in SPZ was shown to have a synergistic effect that benefits the development and kidney health of rats, demonstrating its potential application in the context of animal nutrition.

Abstract

Academic achievement among elementary school children is influenced by various factors, including nutritional status, diet quality, and nutrition knowledge. These factors play a crucial role in supporting cognitive development and learning performance. This study aimed to analyze the association between diet quality, nutritional status, and nutrition knowledge as predictors of academic achievement among elementary school children. A cross-sectional design was employed, involving 60 students selected using simple random sampling. Nutritional status was assessed using body mass index-for-age (BMI/A), diet quality was evaluated using a diet quality index score (range 0–100), and nutrition knowledge was measured using a standardized questionnaire. Data were analyzed using SPSS version 26. The Kolmogorov–Smirnov test was performed to confirm normality before conducting Pearson correlation and multiple linear regression analyses. The results showed significant correlations between academic achievement and diet quality (r = 0.42; p = 0.0012), nutritional status (r = 0.36; p = 0.0045), and nutrition knowledge (r = 0.28; p = 0.0321). Multiple regression analysis revealed that all three variables were significant predictors of academic achievement, with R² = 0.42 and adjusted R² = 0.39, indicating that 39% of the variance in academic achievement was explained by these predictors. In conclusion, diet quality, nutritional status, and nutrition knowledge contribute significantly to improving academic achievement among elementary school children.
