- Abstract
Background -- Our two-year school milk intervention trial with Beijing Chinese girls aged 10 years showed that 330 ml milk supplement (fortified with vitamin D and/or calcium) on school days had resulted in greater increases in regional (pelvis, left leg and right leg) bone mineral content (BMC) and bone mineral density (BMD). Objectives -- To assess whether these effects were sustained 3 years after the supplement withdrawal. Design -- Regional BMC and BMD were reassessed in 274 of the 375 girls whose regional bone mineral data have been studied at the end of the intervention, with 87 from the group received calcium fortified milk (Ca milk), 82 from the group received calcium and vitamin D fortified milk (CaD milk), and 89 from the control group. The measurements were made at the same dual-energy X-ray absorptiometry (DEXA) machine by the same technicians. Outcomes -- Three years after the cessation of milk supplementation, there were no significant differences between the three groups in the changes of BMC and BMD of pelvis, left leg and right leg from baseline, after adjusted for age and corresponding baseline values. Conclusion -- The benefit of milk supplementation on regional bone mass accretion had disappeared three years after the cessation of milk supplementation. Two years milk supplementation in Chinese pubertal girls is unlikely to have long-lasting effects on their bone mineral accretion. Short-term milk supplementation is not adequate to promote optimum peak bone mass for Chinese children.
