Prior to pregnancy, 5.9%, 20.9% and 13.3% of women
were underweight, overweight and obese, respectively
(Figure 1). During pregnancy, 18.1% of women gained
below the recommended weight, while almost one-half
(48.8%) gained above the recommended weight (Figure
2). See Table 1 for BMI-specific GWG recommendations.
Underweight BMI and below recommended GWG were
associated with younger maternal age, being nulliparous,
low socioeconomic status, urban residence and being
of East/South Asia/Pacific ethnicity, while overweight
and obese BMI and above recommended GWG were
associated with being parous, living in Atlantic Canada
or the territories and a history of depression.
