Association between TBLH BMC and TBLH BA measured at 9.9 years of age and risk of fracture over the following 2 years. Table shows ORs for fracture per SD decrease in TBLH BMC or TBLH BA calculated by logistic regression. Minimally adjusted models adjusted for age, sex, ethnicity, and socio-economic status. Additional models are shown in which analyses are adjusted for height and/or log-transformed weight and for TBLH BMC additionally adjusted for TBLH BA.
