Sex-related differences in the sagittal plane spinal angles in preschool and school-age children

Abstract Study aim : The study aimed to assess the differences in magnitude of anterior-posterior spinal curvatures depending on sex children aged 5 and 9 years. Material method s: This prospective longitudinal observational included 67 (29 girls 38 boys) pre-school-age school-age phases (the first examination at years old second old). Measurements body weight height were recorded. computerized assessment posture was performed with photo-grammetric (MORA 4 Generation). normality distribution variables assessed Shapiro-Wilk test. Mann-Whitney U test used analyze between sexes terms parameters somatic parameters. Results There no statistically significant sex-related values 5-year-old children. In group 9-year-old angle lumbar lordosis, a difference found (U = 387.00, p < 0.05). Girls had significantly higher mean value lordosis than boys same age (p Conclusions A Understanding gender differentiation is step towards explaining wide variability normal adults developmental biomechanical male female spines.
