Brief 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.

Condition or disease Intervention/treatment Phase
Bone Development Dietary Adequacy Behavioral: Adequate Calcium Today Not Applicable

Detailed 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.

Intervention Details:
  • Behavioral: Adequate Calcium Today
    A school-randomized behavioral intervention study called the Adequate Calcium Today (ACT) project was conducted in sixth grade classrooms located in six states (Arizona, California, Hawaii, Indiana, Nevada, and Ohio).


Primary Outcome Measures :
  1. Change in Bone Mineral Content [ Time Frame: 18 months ]
    Baseline, 12 month and 18 month bone mineral content measured

  2. Dietary Calcium [ Time Frame: 18 months ]
    Dietary Calcium intake assessed by food frequency questionnaire


Secondary Outcome Measures :
  1. Lactose maldigestion [ Time Frame: Baseline ]
    Measured by breath hydrogen testing


Other Outcome Measures:
  1. Perceived lactose intolerance [ Time Frame: Baseline ]
    Measured by questionnaire
