An Indigenous Birth Cohort
The objectives of this study are:
- to determine the major antenatal maternal factors (e.g. pre-pregnancy weight, weight gain, dietary intake, physical activity, and smoking exposure), selected paternal factors (e.g. cigarette smoking), and pregnancy factors (e.g. maternal weight gain, smoking exposure, glucose intolerance, and pregnancy-induced hypertension) which are associated with the newborn’s adiposity and cardio-metabolic factors at birth, and annually for the first three years of life;
- to determine the association between early feeding practices (i.e. exclusivity of breastfeeding, formula feeding, type, frequency and duration of breast/bottle feeding, and growth after weaning), sleep patterns and activity on newborn’s adiposity, and related cardio-metabolic factors annually for the first 3 years of life and;
- to determine the impact of the home environment, including socio-economic status, social support, and maternal psychosocial factors on newborn’s adiposity at birth and annually for the first three years of life.
