Iron anemia is the biggest macro nutritional problem in Indonesia, which occurs in toddlers, pregnant women and adolescent girls. Adolescent girls with anemia are at risk of giving birth to LBW babies (<2500 grams), giving birth to premature babies, neonatal infections and death in the baby's mother during delivery. The aim of this study was to analyze the relationship between screen time and sleep quality with hemoglobin levels in adolescent girls.  This research method uses quantitative observational research with a cross-sectional design and a sample size of 76 respondents using a purposive sampling technique.

And the category of poor sleep quality was 57 respondents (75.0%) and good sleep quality was 19 respondents (25%).
