Maternal physical activity levels in early pregnancy and the risk of spinal deformity among preschoolers at age 4: findings from the Shanghai birth cohort study.

ABSTRACT:

Objective

To study the impact of maternal physical activity levels before and after birth on the risk of spinal deformity in preschool children.

Methods

A cohort study of 760 preschoolers and their mothers tracked maternal physical activity levels during the prenatal period and the two years postnatally, as well as for two years after the child's birth, using standardized questionnaires at 6, 12, and 24 months. The risk of spinal deformity was assessed by the angle of trunk rotation (ATR) at the thoracic (T5), thoracic-lumbar (T12), and lumbar (L4) segments of the spine, with max values noted. An adjusted logistic regression model was used to explore the relationships between prenatal and postnatal physical activity levels and the risk of spinal deformity in preschoolers.
