Environmental Health Risk Perceptions and Protective Actions: A Mixed-Method Study of New Mothers in Ontario, Canada

This thesis examines mothers’ risk perceptions and protective actions as they relate to their children’s environmental health. Children are more exposed and vulnerable than adults to environmental hazards, which have been found to be associated with numerous immediate and long-term negative health outcomes, due to physiological and behavioural factors. Despite the responsibility mothers typically bear as primary caregivers to their children, little is known about how they perceive and negotiate these risks in their day-to-day lives. To better understand mothers’ perceptions and associated protective actions across socioeconomic and geographic contexts, a mixed-method approach was employed involving a quantitative telephone survey (n=606) in Peel Region and Ottawa Public Health Units and qualitative face-to-face interviews (n=15) in Ottawa. Risk perceptions were influenced by income and perceived control, and concerns ranged from chemicals in household products to outdoor air pollution. There was a commonly reported perception that mothers should automatically become more concerned and take protective actions once they have children. When financial or other barriers prevented mothers from taking direct action to reduce risks, such as switching to safer products or changing food habits, they may have relied on emotion-focused coping techniques to reduce feelings of concern, including choosing to ignore risk information. Mothers’ information sources were examined to understand how risk information is best internalized; while the most common source of environmental health risk information was the Internet, many mothers expressed their mistrust in it and would have preferred to receive information directly from healthcare providers. This research contributes to the understanding of risk perception and protective action in a largely understudied population and the findings have practical implications for risk management and communication strategies targeting pregnant women and new mothers
