Iron and zinc deficiency affect adolescent school girls’ behavior

Background: Iron and zinc are important trace elements in humans. Deficiencies in these elements have been reported in several studies. However, few studies have investigated blood examination results in conjunction with human behavior. Thus, this study aimed to analyze students’ exercise, daily habits, and behavior in combination with blood laboratory examinations over a two-year study period.Methods: Healthy female junior high and high school students were recruited between 2020 and 2021.
