Specific birth and newborn care practices that were explored with all participants included selecting delivery location, birth preparedness and complication readiness, drying and wrapping the baby after delivery, bathing, immediate and exclusive breastfeeding, cord care, care seeking and care for small babies.
Comparative data from Australia in 2009 shows 96.9% were hospital births, 2.2% birth centre (primary unit), 0.03% home and 0.06% 'other' location births [ 22].
We also wished to explore why the location of birth was chosen and the selection of birth attendants.
Birth certificates provided maternal reproductive history and residence location at birth.
Each observation contained variables for the residential location at birth; pregnancy-related risk factors (e.g., average number of cigarettes smoked per day during pregnancy, birth order); and sociodemographic risk factors (e.g., race/ethnicity, maternal age).
The type of choices advocated for include the geographical location of birth [ 48], model of care received [ 33, 36], choice of who is present at the birth and whether culturally important protocols are adhered to [ 15].
