<![CDATA[Nutritional problems during the Covid-19 pandemic are one of the problems that need attention among adolescents. Nutrition education which is carried out regularly in the form of nutrition classes is expected to influence nutritional knowledge, nutritional status, and hemoglobin levels in adolescents. The purpose of this study was to determine the effect of providing nutrition education in the form of nutrition classes on knowledge, nutritional status, and hemoglobin levels of adolescents during the Covid-19 pandemic. This study was an experimental study with a quasi-experimental one-group design with pre-test – post-test. The sample in this study were students of Al-Istiqomah Wanasari Islamic Boarding School in Bandung. The intervention was carried out for 3 months with 6 meetings online. Nutritional knowledge was measured using an online form, nutritional status was measured by BMI for Age indicators, and hemoglobin levels were measured through peripheral blood vessels. Analysis of the data was used dependent sample t-test for normally distributed data. Data that are not normally distributed are performed by the Wilcoxon test. The average nutritional knowledge, nutritional status, and hemoglobin levels of the samples before intervention were 14.75, 0.19, and 14.36 mg/dl, after the intervention increased to 18.06, 0.24, and 15.45mg/dl. Nutrition education in the form of online nutrition classes affected increasing nutritional knowledge (p-value=0.000) and hemoglobin levels (p-value=0.001) after an intervention. Online nutrition classes can be conducted during the Covid-19 pandemic to increase adolescent nutrition knowledge in achieving optimal health status.]]>
