Abstract: Adequate nutrition is the basis for healthy growth of preschool children. Malnutrition will lead to growth retardation, which will affect their physical and brain development and prevent them from performing their full potential. Nutritional intake is closely related to preschool children's dietary behaviors. And their dietary behaviors are mainly affected by the caregivers' feeding patterns. Therefore, the caregiver's feeding pattern is an important factor affecting growth and development of preschool children. This paper reviews the research progress on evaluation measures of preschool children's dietary behaviors and its relationship with nutritional status worldwide, in order to provide evidence for scientific evaluation and improvement of their nutritional status.
