To determine the cut-off values for low birth weight (LBW) and high birth weight (HBW) of Sudanese newborns.
Data (maternal age, parity, birth weight, and gender of the newborn) from women (n = 2818) who delivered at Saad Abualila Hospital in Khartoum were retrieved from the medical files.
The cut-off for LBW (the 10th centile) was 2400 g and the 90th centile (HBW) was 3700 g. Out of 2818 newborns, 317 (11.2%) had birth weights below 2400 g. Using the WHO (traditional) cut-off of 2500 g, the prevalence of LBW was 14.3%. The difference between the two prevalences of LBW was statistically significant (P < 0.001). However, the agreement rate between the two was high (κ = 0.86). The cut-off to define HBW was 3700 g. In the study, 292 (10.4%) newborns had birth weights of at least 3700 g. Using the cut-off of 4000 g, the prevalence of HBW was 9.5%. The difference between the two prevalences of HBW was statistically significant (P < 0.001). However, the agreement rate between the two was low (κ = 0.06).
The cut-off values for low and high birth weight were 2400 and 3700 g, respectively.
确定苏丹新生儿低出生体重（LBW）和高出生体重（HBW）的截断值。
从喀土穆 Saad Abualila 医院的产妇病历中检索了 2818 名分娩妇女（n=2818）的资料（母亲年龄、产次、新生儿出生体重和性别）。
LBW（第 10 百分位数）的截断值为 2400g，第 90 百分位数（HBW）为 3700g。在 2818 名新生儿中，有 317 名（11.2%）的出生体重低于 2400g。使用世界卫生组织（传统）的 2500g 截断值，LBW 的患病率为 14.3%。这两种 LBW 患病率之间的差异具有统计学意义（P<0.001）。然而，两者之间的一致性很高（κ=0.86）。定义 HBW 的截断值为 3700g。在这项研究中，有 292 名（10.4%）新生儿的出生体重至少为 3700g。使用 4000g 的截断值，HBW 的患病率为 9.5%。这两种 HBW 患病率之间的差异具有统计学意义（P<0.001）。然而，两者之间的一致性较低（κ=0.06）。
低出生体重和高出生体重的截断值分别为 2400g 和 3700g。
