Abstract

The body's immune system plays a significant role in fighting viruses that enter the body. One way to increase immunity is by providing adequate intake for the body, one of which is vitamin C. Food sources containing vitamin C are important in supporting immunity because they serve as antioxidants. Nutrition knowledge is essential for adolescents to know which food groups are high in vitamin C. However, 37.83% of students showed inadequate knowledge on this issue. This study aims to determine the difference in vitamin C intake based on nutrition knowledge and immunity in the new normal era among students of SMK Penda 3 Jatipuro Karanganyar, Central Java Indonesia. This is analytical observational quantitative research using a cross-sectional design. The subjects were adolescents in vocational schools who met the inclusion criteria. This study involved 81 samples taken using a simple random sampling technique. The data used were primary data obtained from nutrition and immunity knowledge questionnaires and SQ-FFQ forms over the last 3 months. The statistical tests used were the independent t-test and Mann-Whitney U test. The results of this study show that adolescents with good knowledge account for 54.3%, while adolescents with good intake are 61.7%. Adolescents with good knowledge and good intake have an average vitamin C intake of 120.7 mg and adolescents with inadequate knowledge have an average intake of vitamin C of 98.7 mg. The test differences for gender, age, maternal education, parental income, place of residence, social media use, television use and knowledge are 0.084; 0, 0526; 0,094; 0,018; 0,428; 0,019; 0.929 and 0.036 respectively. This study concludes that there are differences in vitamin C intake among students in the new normal era based on their parents’ income, social media use, and nutrition and immunity knowledge. This study recommends that adolescents should maintain their vitamin C intake and increase their nutrition knowledge concerning the sources of vitamin C and the role of vitamin C in immunity.
