Abbreviations: CI = confidence interval; OR = odds ratio; IDD = intellectual/developmental disability.
In multinomial logistic regression, each odds ratio can be understood as the product of one 2x2 table. For each table the exposure is the particular characteristic independently being compared to the referent category of that specific characteristic and the outcome is prenatal care adequacy level (no/unspecified care, inadequate, or intensive) compared to adequate care.
N represents the number of individuals that fall into that specific category, while the percent represents the proportion of people in that category relative to their respective continuity of care category.
Adjusted model controls for maternal age, parity, disability type, neighbourhood income quintile, rurality, pre-pregnancy chronic medical conditions, mental illness, and substance use disorders.
No prenatal care visits with a physician.
