Tang JJ, et al. - Researchers examined how prepregnancy impaired fasting glucose defined by the WHO cut-point influence the risk of preterm birth and large for gestational age. In addition, they examined the appropriateness of the WHO cut-point of impaired fasting glucose in identifying women at the risk of preterm birth and large for gestational age among the Chinese population. From the National Free Preconception Health Examination Project with singleton birth from 121 counties/districts in 21 cities of Guangdong Province, China, from January 1, 2013 to December 31, 2017, they included 640,469 women in this retrospective cohort study of women. As per data gained, the risk of preterm birth, large for gestational age and severe large for gestational age increases in correlation with maternal prepregnancy impaired fasting glucose. In addition, data suggest too restrictiveness of the WHO cut-point of impaired fasting glucose and that lesser levels of fasting glucose also increase the risk of large gestational age and severe for severe gestational age in the Chinese population.
