The Atlantic Provinces have a higher proportion of low birthweight births than most other areas in Canada. As one moves west through the Prairies, then to British Columbia, and finally to the territories, the low birthweight births decrease by region. Low birthweight (LBW) is a health status indicator, and is defined as babies born with weight under 2500 grams. The proportion of low birthweight babies born to mothers 15 years of age and older indicates the health and well-being of a population. Health status refers to the state of health of a person or group, and measures causes of sickness and death. It can also include people’s assessment of their own health.
