MONTIJO-BARRIOS, Ericka et al. Bone mass accretion in healthy Mexican 6 to 12 year-olds measured by DEXA. Salud pública Méx [online]. 2009, vol.51, n.3, pp. 227-230. ISSN 0036-3634. http://dx.doi.org/10.1590/S0036-36342009000300013.
OBJECTIVE:To describe bone mass density in a group of healthy 6 to 12 year-old Mexican children by a peripheral DEXA, adjusted for gender. MATERIAL AND METHODS: A cross-sectional study between 2006 and 2007 conducted in 1 965 children (982 male), without any medical condition, randomized from elementary schools in Mexico City. RESULTS:Changes in bone mineral density in girls show two phases: a lineal accretion (6-9 years) and an exponential curve (10 years and older); in boys these growth rates are less pronounced. CONCLUSIONS:It is considered that optimal interventions to improve bone mass density and peak bone mass should be performed between 6 to 12 years of age.
