Early-life famine exposure, adulthood obesity patterns, and risk of low-energy fracture

Frontiers of Medicine doi: 10.1007/s11684-023-1023-9

Abstract: osteoporosis, but the association of early-life undernutrition combined with adulthood obesity patterns with low-energyfracture remains unknown.Low-energy fracture was defined as fracture occurring after the age of 40 typically caused by falls fromearly-life famine exposure interacts with adulthood general obesity and significantly increases the risk of low-energyfracture later in life in women.
