Risk Profile Classes

The lifestyle behavioural risk class was the largest group and included just over half of participants. The nutritional and environmental class grouped women with poor dietary diversity, low physical activity, and high environmental or household exposure. The social determinants class was primarily characterized by low education, lack of community health insurance, and dental or periodontal problems. The reproductive and biomedical class had high probabilities of chronic medical conditions, infectious diseases, maternal age risk, and prior adverse pregnancy outcomes. The lifestyle behavioural risk class was defined by insufficient sleep, appetite loss, alcohol use, and excessive coffee consumption.
