Iron deficiency anemia in relation to pinch strength and hand dexterity in preschool children: a cross-sectional study

Background

Iron deficiency anemia (IDA) constitutes a considerable nutritional problem in Egyptian preschool children. Moreover, IDA limits physical activity performance and interferes with children's development. Accordingly, we aim to investigate the correlation between IDA and hand dexterity and pinch grip strength in preschool children.

Results

This observational cross-sectional study encompassed the participation of 87 children, comprising both genders, with an age range of 5–6 years. The cohort was initially stratified into three distinct groups: Group A comprised 36 non-anemic children, group B included 25 children with mild iron-deficiency anemia (IDA), and group C consisted of 26 children with moderate IDA. After group delineation, comprehensive laboratory analyses were performed on all participants to assess for IDA, involving a thorough examination of their complete blood picture, hemoglobin (Hb) levels, serum iron levels, and serum ferritin levels. The evaluative metrics employed in this study encompassed the Bruininks-Oseretsky Test of Motor Proficiency-Second Edition (BOT-2) and the Baseline Mechanical Pinch Gauge. These instruments were utilized to assess manual dexterity and pinch strength, specifically tip-to-tip and tripod strength. This investigation revealed a positive correlation between Hb, serum iron, and serum ferritin levels with both manual dexterity and pinch strength across all three groups.

Conclusion

This study highlights that IDA negatively affects hand dexterity and pinch grip strength in preschool children. Managing IDA early is crucial for improving their physical performance and overall development.
