Improving Bone Health in Adolescence Through Targeted Behavioral Intervention

Bone Development Clinical Trial

Official title: Improving Bone Health in Adolescence Through Targeted Behavioral Intervention

Status Completed

Clinical Trial Summary

School based educational intervention to educate on bone health among Hispanic, Asian or non-Hispanic white girls between 10-13 years with end points of knowledge gained, calcium intake and bone density in . The hypothesis was that the educational program would increase knowledge, improve dairy food and calcium consumption and enhance bone health in this population. A secondary hypothesis was that lactose maldigestion would be an impediment to improved dairy food consumption.

Clinical Trial Description

A targeted behavioral intervention to improve calcium intake and bone mass was conducted at middle schools in 6 states. The primary outcomes of bone mass and dietary calcium were assessed among Asian, Hispanic, or non-Hispanic white girls between 10 -13 y. Lactose maldigestion (LM) was determined by a breath hydrogen test (BHT). Perceived milk intolerance (PMI) and calcium intake were assessed by questionnaires and bone mineral content (BMC) was determined by dual energy X-ray absorptiometry (DXA). Data from 473 girls were used in a multiple linear regression to examine the impact of the intervention while accounting for PMI and LM and adjusting for covariates. ;
