one mineral density (BMD) increases progressively during childhood and adolescence and is affected by various genetic and
environmental factors. The aim of this study was to establish reference values for lumbar BMD in healthy Chinese infants and
young children and investigate its influencing factors. Healthy children aged 0 to 3 years who underwent regular physical examinations
at the Child Health Care Clinic of Hubei Maternal and Child Health Hospital (N=11,898) were recruited for this study. We also
chose 379 preterm infants aged 0 to 1 years to preliminarily explore the development of BMD in this special population. BMD (g/
cm
2
) measurements of the lumbar spine (L2–L4) were carried out with dual-energy X-ray absorptiometry and a questionnaire was
administered to full-term children’s parents to gather information on various nutritional and lifestyle factors as well as mothers’
nutritional supplement use during pregnancy. Lumbar BMD significantly increased with age among both boys and girls (p=0.05),
with fastest growth observed during the first postnatal year. There was no significant difference in lumbar BMD between boys and girls
of similar age (p=0.05), either among healthy reference children or preterm infants. However, BMD values in preterm infants were
significantly lower than those in term infants three to eight months old (p=0.05) after adjustment for gestational age. Multivariable
linear regression analysis indicated significant positive associations between lumbar BMD of healthy children and the child’s age
and current weight, mother’s weight gain during pregnancy, birth weight, children’s outdoor activity duration and children’s physical
activity duration. Our study provides reference values of lumbar BMD for healthy Chinese children aged 0 to 3 years and identifies
several influencing factors.
