An interventional study of Adequate Calcium Today in Bone Development and Dietary Adequacy, sponsored by Purdue University. Completed at 1 site in United States. Open to female participants aged 10 Years to 13 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2014-07-29.
Sponsored by Purdue University · Not applicable, Interventional, and Prevention
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.
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.
Purdue University is the lead sponsor of 168 studies on the registry; 23 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Middle schools within one-hour driving time of one of the designated DXA measurement sites were eligible to participate in ACT if their student population had a higher proportion of Asian or Hispanic students than the respective state's average. - Girls recruited for evaluation measures were limited to those being at least 75% Asian, Hispanic or non-Hispanic White based on the race/ethnicity of their biological parents.
