However, studies related to negative Oral Glucose Tolerance Test (OGTT) results in the second trimester but dysglycemia in late pregnancy on maternal and infant pregnancy outcomes are rare.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a nest case-control study within the Xi'an Longitudinal Mother-Child Cohort study (XAMC) to investigate the risk of adverse pregnancy outcomes in mothers and children with maternal negative mid-pregnancy OGTT results but high glycated hemoglobin (HbA<jats:sub>1c<\/jats:sub>) levels (\u22655.7%) in late pregnancy. All target women who delivered from January 1st, 2017 to December 31st, 2018 in Northwest Women's and Children's Hospital in Xi'an were enrolled as the case group (HbA<jats:sub>1c<\/jats:sub> \u2265 5.7%). Others with HbA<jats:sub>1c<\/jats:sub> &amp;lt; 5.7% but without GDM were selected as the control group (HbA<jats:sub>1c<\/jats:sub> &amp;lt; 5.7%) by matching with the same delivery period.

The differences in other outcomes were not statistically significant. The multiple logistic regression analysis showed that gestational age, fetal length, prenatal HbA<jats:sub>1c<\/jats:sub>, and total cholesterol (TG) were independent risk factors for newborns with large-for-gestational-age (LGA).
