| Popis: | Background: High birthweight may predispose children to acute lymphoid leukemia, whereas low birthweight is associated with childhood morbidity and mortality. Low and high birthweight have been inconsistently associated with mortality in children with leukemia. Material and methods: In a cohort of childhood and adolescent leukemia (0–19 years) patients from registries in Denmark, Norway, Sweden, and Washington State in the United States (1967–2015), five-year all-cause mortality was assessed by birthweight and other measures of fetal growth using the cumulative incidence function and Cox regression with adjustment for sex, diagnosis year, country, the presence of Down’s syndrome or other malformations, and type of leukemia. Results: Among 7148 children and adolescents with leukemia (55% male), 4.6% were low (1–2 years old; 1.0 (95% CI: 0.6, 1.5) for 3–8 years old; 1.0 (95% CI: 0.6, 1.8) for 9–13 years old; and 1.2 (95% CI: 0.7, 2.1) for 14–19 years old, and were similar for size for gestational age and Ponderal index. In analyses restricted to children born full term (37–41 weeks of gestation), results were only slightly attenuated but risk was markedly increased for infants aged ≤1 year (HR for low birthweight = 3.2, 95% CI: 1.2, 8.8). Conclusion: This cohort study does not suggest that low birthweight or SGA is associated with increased five-year all-cause mortality risk among children with any type of childhood leukemia or acute lymphoblastic leukemia, specifically, beyond infancy. |
