Abstract
Background: Caregiver sense of physical and mental burden differs depending on their health and psychological state. Given that they may be in poor health due to long hours of caregiving and nighttime care, they are expected to be under undue stress. Although anemia may influence the sense of fatigue among elderly caregivers, no study has assessed the relationship between their hematopoietic state and amount of physical activity. The present study aimed to assess the relationship between anemia-related parameters that reflect hematopoietic function and amount of physical activity in caregivers.
