Malnutrition in early life increases the risk of osteoporosis,but the association of early-life undernutrition combined with adulthood obesity patterns with low-energy fracture remains *** study included 5323 community-dwelling subjects aged⩾40 years from ***-life famine exposure was identified based on the participants’birth *** obesity was assessed using the body mass index(BMI),and abdominal obesity was evaluated with the waist-to-hip ratio(WHR).Low-energy fracture was defined as fracture occurring after the age of⩾40 typically caused by falls from standing height or *** to the nonexposed group,the group with fetal,childhood,and adolescence famine exposure was associated with an increased risk of fracture in women with odds ratios(ORs)and 95%confidence intervals(CIs)of 3.55(1.57–8.05),3.90(1.57–9.71),and 3.53(1.05–11.88),respectively,but not in *** interactions were observed between fetal famine exposure and general obesity with fracture among women(P for interaction=0.0008).Furthermore,compared with the groups with normal BMI and WHR,the group of women who underwent fetal famine exposure and had both general and abdominal obesity had the highest risk of fracture(OR,95%CI:3.32,1.17–9.40).These results indicate that early-life famine exposure interacts with adulthood general obesity and significantly increases the risk of low-energy fracture later in life in women.

Glucose-6-phosphate dehydrogenase(G6PD)deficiency is one of the most prevalent hereditary and X-linked enzyme disorders caused by the pathogenetic G6PD(NM_001042351.2)variants(Yang et al.,2016).The clinical manifestations of G6PD deficiency offer a wide spectrum of diverse disease phenotypes(Hecker et al.,2013).Investigations of prevalence and molecular epidemiology demonstrate that G6PD deficiency affects over 400 milion individuals worldwide and leads to thousands of deaths annually(Mortality and Causes of Death,2015).
