Abstract:
Objective:To explore the relationship between famine exposure in early life and bone mineral density measured by ultrasound in postmenopausal women.Methods:From May 2011 to October 2011, 10 140 residents over 40 years old in Yunyan District of Guiyang City were randomly selected, and followed up for 3 years, 7 493 subjects were selected and finally included a total of 1 504 subjects. Grouped by date of birth, the differences in bone mineral density measured by ultrasound, and risk of osteoporosis between the exposed and non-exposed groups were compared.Results:SOS, T-score, and QUI in infant- and preschool-exposed group were lower than those of non-exposed group. The medium/high risk of osteoporosis in non-exposed, fetal-exposed, infant-exposed, and preschool-exposed groups were 50%, 46.8%, 58.4%, and 62.8%, respectively ( P<0.01). Multivariate linear regression analysis showed that famine exposure in infant- and preschool-exposed groups were significantly negative correlated with SOS, T-score, and QUI, while fetal-exposed group was not significantly correlated with SOS, T-score, and QUI. Compared with the non-exposed group, the OR of the medium/high risk of osteoporosis in the infant- and preschool-exposed groups were( OR=1.41, 95% CI 1.02-1.96)、( OR=1.68, 95% CI 1.21-2.34), with statistically significance ( P<0.05), and there was no statistical significance in the fetal-exposed group. After adjusting for confounding factors, the medium/high risk of osteoporosis in infant- and preschool-exposed group were 1.64 and 1.90 as compared with the non-exposed group ( OR=1.64, 95% CI 1.16-2.32, P<0.05 and OR=1.90, 95% CI 1.35-2.70, P<0.05). Conclusion:In postmenopausal women, famine exposure in early life was significantly negatively correlated with bone mineral density measured by ultrasound (SOS, T-score, and QUI), and was associated with an increased risk of osteoporosis.
