Background: The COVID-19 pandemic that has spread throughout the country has caused changes in behavior patterns due to social restrictions. This has resulted in activities outside the home and in open spaces being limited and even abolished and replaced with online activities (in the network). Students who usually take part in teaching and learning activities and do sports and extracurricular activities that they like at school turn into online activities at home. Teenagers cannot socialize with their friends and their space becomes limited during the Covid-19 pandemic so they tend to play social media and get a lot of sleep disorders and experience depression. In addition to changing activities, adolescents' eating patterns and sleep duration also change due to changes in daily routines. This condition affects the nutritional status of adolescents.Objectives: This study was conducted to analyze the relationship between sleep duration, exercise habits, physical activity and eating frequency with the nutritional status of the students of SMAN 22 Surabaya.Method: This research is an analytical observational study conducted at SMA Negeri 22 Surabaya with 170 respondents aged 15-17 years.
