This study aimed to investigate the bile salt-stimulated lipase (BSSL) concentration in the milk of Chinese women and its correlation with maternal body mass index (BMI), gestational diabetes mellitus (GDM) and gestational hypertensive disorder (GHD). The BSSL levels in the milk samples were measured by enzyme-linked immunosorbent assay (ELISA). BSSL level in colostrum milk of mothers with full-term infants was positively correlated with pregnancy week and negatively correlated with maternal pre-pregnancy BMI and BMI late in pregnancy. Moreover, the BSSL concentration in mature milk was positively correlated with BMI gain during pregnancy. The BSSL concentration in colostrum milk was lower in GDM mothers than in normal mothers. The BSSL helps infants digest fat in early life and its level was associated with lactation. The changes in BSSL characteristics with maternal BMI and GDM in this study may have clinical implications regarding the effects of pregnancy weight and metabolism on the nutrition and health of the offspring.
本研究旨在调查中国女性乳汁中胆盐刺激脂肪酶(BSSL)的浓度及其与产妇体重指数(BMI)、妊娠期糖尿病(GDM)和妊娠期高血压疾病(GHD)的相关性。通过酶联免疫吸附测定(ELISA)法检测乳汁样本中的BSSL水平。足月产母亲初乳中的BSSL水平与孕周呈正相关,与孕前BMI及孕晚期BMI呈负相关。此外,成熟乳中的BSSL浓度与孕期体重增加呈正相关。GDM母亲初乳中的BSSL浓度低于正常母亲。BSSL有助于婴儿在生命早期消化脂肪,其水平与泌乳有关。本研究中BSSL特征随产妇BMI和GDM的变化可能对妊娠体重和代谢对后代营养与健康的影响具有临床意义。
