The purpose of this study was to investigate the difference between sleep architecture, sleep characteristics and self-perception of sleep in breastfeeding and formula-feeding mothers 4 and 6 weeks post-partum. Forty-four subjects completed four nights of sleep data on the St.Mary's Hospital Sleep Questionnaire, three nights of wrist actigraphy, and one night of home polysomnography for recording sleep architecture characteristics. Baseline measures included demographics, previous sleep patterns and factors that could impact sleep. Results of an independent t-test indicated no significant differences in total sleep time. Multiple analysis of covariance comparing the sleep architecture characteristics of light sleep, deep sleep, and REM sleep while controlling for age, education level and nicotine use did not demonstrate any significant differences between groups. The variance of the measured sleep characteristic data was greater within the formula feeding mothers. There was a mean of 6.6 hours of sleep in both groups. In contrast to the study being replicated, sleep did not appear to be significantly different in this convenience sample. Mothers reported satisfaction with the quality of their sleep. Wrist actigraphy data reflected more sleep than either polysomnography or self-report. Further research is needed to determine the reasons for this difference.
