All the variables are adjusted according to multivariate models:
M1: Demographic variables (Table 1—pre-existing hypertension and diabetes).
M2: M1+preterm birth—history of spontaneous abortions.
M3: M1—misuse of alcohol or drugs—history of spontaneous abortions.
M4: M1—misuse of alcohol or drugs, BMI and history of spontaneous abortions.
M5: M2—misuse of alcohol or drugs.
Missing data as regard confounding variables in inadequate versus adequate prenatal care group: cohabitation 17.1% versus 9.7%, smoking 10% versus 2.2%, BMI 19.5% versus 2.1%.
BMI, body mass index; UTI, urinary tract infection.
