Abstract:
Objective:To analyze the correlation between homocysteine (Hcy), ferritin and gestational anemia in advanced age pregnant women, and the effect on adverse pregnancy outcomes.Methods:The clinical data of 344 advanced age pregnant women in Handan City Maternal and Child Health Hospital from March 2021 to June 2022 were retrospectively analyzed. The adverse pregnancy outcomes were followed up and recorded. The pregnant women were divided into anemia group (114 cases) and control group (230 cases) according to the diagnostic criteria for anemia. The levels of Hcy and ferritin, etc. were compared between two groups, different degrees of anemia and different pregnancy outcomes. Pearson method was used to analyze the correlation between Hcy, ferritin and hemoglobin. Multivariate Logistic regression was used to analyze the independent risk factors of adverse pregnancy outcomes in advanced age pregnant women with gestational anemia.Results:The Hcy in anemia group was significantly higher than that in control group: (31.39 ± 3.34) mol/L vs. (9.28 ± 1.44) mol/L, the ferritin was significantly lower than that in control group: (69.81 ± 5.08) μg/L vs. (96.43 ± 7.52) μg/L, and there were statistical differences ( P<0.01). Among 114 advanced age pregnant women with gestational anemia, 64 cases were mild anemia (mild anemia group), 35 cases were moderate anemia (moderate anemia group), and 15 cases were severe anemia (severe anemia group). The levels of Hcy in the control group, mild anemia group, moderate anemia group and severe anemia group were gradually increased: (9.28 ± 1.44), (24.79 ± 3.25), (37.63 ± 5.51) and (45.01 ± 7.23) mol/L, the levels of ferritin were gradually decreased: (96.43 ± 7.52), (81.19 ± 5.14), (64.82 ± 4.47) and (32.96 ± 2.01) μg/L, and the difference between pairwise comparisons were statistically significant ( P<0.05). Pearson correlation analysis result showed that Hcy was negatively correlated with hemoglobin ( r = - 0.596, P<0.01), and ferritin was positively correlated with hemoglobin ( r = 0.685, P<0.01). Among 114 advanced age pregnant women with gestational anemia, 35 cases had adverse pregnancy outcomes, and 79 cases had normal pregnancy outcomes. The age, gestational reproductive tract infection rate and Hcy in advanced age pregnant women with adverse pregnancy outcomes were significantly higher than those in advanced age pregnant women with normal pregnancy outcomes: (41.17 ± 3.74) years old vs. (38.25 ± 4.28) years old, 28.57% (10/35) vs. 10.13% (8/79) and (49.56 ± 4.12) mol/L vs. (23.34 ± 2.63) mol/L, the ferritin was significantly lower than that in advanced age pregnant women with normal pregnancy outcomes: (38.36 ± 3.08) μg/L vs. (83.74 ± 6.25) μg/L, and the degree of gestational anemia was more serious than that in advanced age pregnant women with normal pregnancy outcomes, and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis result showed that age, gestational reproductive tract infection, Hcy, ferritin and the degree of gestational anemia were the independent risk factors of adverse pregnancy outcomes in advanced age pregnant women with gestational anemia ( OR = 1.570, 1.758, 1.865, 1.556 and 1.652; 95% CI 1.154 to 2.136, 1.181 to 2.617, 1.223 to 2.842, 1.100 to 2.201 and 1.175 to 2.323; P<0.01). Conclusions:The level of Hcy in advanced age pregnant women with gestational anemia is relatively higher, and the level of ferritin is relatively lower. The ferritin and Hcy levels are risk factors for adverse pregnancy outcomes in advanced age pregnant women with gestational anemia, and may be involved in the occurrence and development of gestational anemia in advanced age pregnant women.
