From: Effects of the energy balance transition on bone mass and strength
Among women in the modern-day sample, the presence of overweight and obesity significantly affected bone mass and strength properties of the tibial mid-diaphysis, including maximum second moment of area (Imax; top left), minimum second moment of area (Imin; top right), cortical bone area (Ct.Ar; bottom left), and polar second moment of area (J; bottom right). All properties were size standardized prior to analysis using both measured body weight and body weight estimated based on skeletal frame size (SFS). Imax, Imin, and J values were standardized by dividing by the product of body weight (estimated or measured) and tibial articular length2, and units in the figure are mm4/(kg·mm2)·105. Ct.Ar values were standardized by dividing by body weight (estimated or measured), and units in the figure are mm2/kg·102. Bars are least squares means + standard errors from tests that controlled for age. Significance codes: not significant (ns), p < 0.05 (*).
