Multivariable logistic regression analysis of the associations among anemia, GHP, GDM and IPI (Table 3)
With an IPI of 24-59 months as the reference category, our analysis suggested that an IPI of less than 24 months was related to an increased risk of developing anemia in late pregnancy (adjusted odds ratio (aOR) 2.09, 95% CI 1.21-2.62, p = 0.008), while an IPI of 60 to 119 months or 120 months or greater was not associated with anemia in the third trimester (IPI of 60 to 119 months, aOR 1.37, 95% CI 0.94-1.98, p = 0.098; IPI of 120 months or greater, aOR 1.39, 95% CI 0.81-12.38, p = 0.232). IPIs of less than 24 months, 60 to 119 months, and 120 months or greater had no significant effect on the risk of developing GHP or GDM.
