PRIMARY outcome

Timeframe: 1-month postpartum (approximately)

Population: ITT analysis. Because this was a repeated measures analysis at 1 and 3 months postpartum, subjects missing outcome data at either point were excluded from the analysis.

Maternal sleep quantity is defined as total night-time sleep in hours as measured by wrist actigraphy over 3 nights.

Population: ITT analysis. Because this was a repeated measures analysis at 1 and 3 months postpartum, subjects missing outcome data at either point were excluded from the analysis.

Maternal sleep quality is defined as sleep efficiency (percent sleep per time in bed averaged across 3 nights) as measured by wrist actigraphy.

PRIMARY outcome

Timeframe: 24 hours before and 24 hours after immunizations at approximately 2 months of age

Population: ITT analysis. Infants who were not immunized or did not have valid outcome data were excluded from the analysis.

Change in infant sleep quantity is defined as the difference between the number of hours slept in the 24 hours prior to immunization and the the number of hours slept after immunization (positive numbers indicate more sleep following immunization). Infant sleep was measured by ankle actigraphy.

SECONDARY outcome

Timeframe: 1 month postpartum (approximately)

Population: ITT analysis.

Maternal sleep disturbance is measured by the total score on the General Sleep Disturbance Scale (GSDS). The GSDS is a self-report questionnaire that measures perceived sleep disturbance in the past week. GSDS scores range from 0 to 147, with higher scores indicating more sleep disturbance.

SECONDARY outcome

Timeframe: 1 month postpartum (approximately)

Population: ITT analysis.

Maternal well-being was measured by the total score on the Center for Epidemiologic Studies - Depression Scale (CES-D). The CES-D measures depressive symptoms in the past week. CES-D scores can range 0 to 60, with higher scores indicating more symptoms of depression.
