Abstract | CONTEXT: OBJECTIVE: DESIGN AND SETTING: Subjects were mainly participants from 2 population-based cohort studies: the LIFE Child study of children and adolescents and the LIFE Adult study. PARTICIPANTS: We investigated 9400 serum samples from more than 7000 healthy and 1278 obese subjects between 3 months and 81 years old. MAIN OUTCOME MEASURES: Associations between IGF-I or IGFBP-3, measured with a new electrochemiluminescence immunoassay, and the predictors BMI and CDs were estimated using hierarchical linear modeling. RESULTS: During infancy, obese children had up to 1 SD score (SDS) higher mean predicted IGF-I values, converging with levels of normal-weight subjects up to 13 years old. Between 20 and 40 years of age, obesity was related to up to -0.5 lower IGF-I SDS values than the predicted values. Obesity had less impact on IGFBP-3. Estrogen- and progestin-based CDs, but not HRT, decreased IGF-I and increased IGFBP-3 (P < 0.01) in adolescents (β IGF-I = -0.45, β IGFBP-3 = 0.94) and adults (β IGF-I = -0.43, β IGFBP-3 = 1.12). Conversely, progestin-based CDs were significantly positive associated with IGF-I (β IGF-I =0.82). CONCLUSIONS: BMI and CDs must be considered when assessing and interpreting the clinical relevance of IGF-I and IGFBP-3 measurements.
