Abstract

Background: Depression disorder is a significant mental health issue occurring among adolescents worldwide. Omega-3 fatty acids, vitamin B9, and vitamin B12, influences the body's produced neurotransmitters, especially serotonin, dopamine, and norepinephrine. These neurotransmitters are neurobiological factors contributing to depression disorders. Levels of serotonin, dopamine, and norepinephrine in the body can aid in depression prevention. Objective: This research aims to analyze the correlation between the intake of omega-3 fatty acids, vitamin B9, vitamin B12, and depression symptoms in female adolescents at SMAN 9 Semarang. Methods: This research is observational research with a cross-sectional design, involving 118 female adolescents aged 14 – 18 years. It is selected through non-probability sampling using purposive sampling. Depression symptoms are measured using the BDI-II (Beck’s Depression Inventory) questionnaire, while omega-3 fatty acids, vitamin B9, vitamin B12 are measured using SQ-FFQ (Semi Quantitative Food Frequency Questionnaire). Bivariate data analysis using Chi-Square test and multivariate data analysis using logistic regression. Results: About 30% of female adolescents in X, XI, and XII grades are classified as having moderate depression with a deficiency in omega-3 intake (91.2%), vitamin B9 (88.2%), and vitamin B12 (85.3%). Multivariate analysis showed a relationship between vitamin B9 intake and depressive symptoms in female adolescents (p = <0,001). Conclusion: There is a relationship between vitamin B9 intake and depressive symptoms in female adolescents.

Abstract

Background: Iron deficiency anemia may result from inadequate iron intake or hindered iron absorption. Black tea is known to contain tannins, compounds that can interfere with the body’s ability to absorb iron. Rice husk ash, which is rich in silica, has the potential to lower the tannin content in black tea. Objective: This study aimed to examine the impact of rice husk ash supplementation on the tannin content of black tea. Methods: An experimental study was carried out using a completely randomized design involving four treatment groups: control (P0), soaking (P1), boiling followed by soaking (P2), and boiling plus soaking with 15% rice husk ash (P3). The tea samples were prepared in the Culinary Dietetics Laboratory, Department of Nutrition Science, Faculty of Medicine, Universitas Diponegoro. Analysis of tannin and phenolic content was performed at Chemix Pratama Laboratory in Yogyakarta using spectrophotometric techniques. The study took place between December 2024 and April 2025. Results: The highest tannin concentration was observed in the control group (P0), averaging 9.05% ± 0.09, while the lowest was recorded in the P3 group (treated with rice husk ash), with an average of 4.66% ± 0.14. A statistically significant difference in tannin levels was found between the P2 and P3 groups (p < 0.05). Additionally, a very strong positive correlation between tannin and phenolic content was identified (r = 0.99; p < 0.05). Conclusion: The combined treatment of boiling and soaking black tea with 15% rice husk ash effectively reduces tannin content. The most notable decrease in tannin levels was seen in the boiling plus soaking with 15% rice husk ash group, indicating this method's potential in reducing compounds that inhibit iron absorption.
