Improving Care Giver Adherence to Recommended Infant Care Practices

This study aims to improve adherence to American Academy of Pediatrics safe sleep (SS) recommendations and improve rates of initiation and duration of partial and exclusive breastfeeding (BF) through direct education of mothers using Mobile Health (mHealth) technologies (ex. text messaging).

Study Overview

Detailed Description

The goal of this study is to assess the effectiveness of mHealth prenatal and postnatal interventions aimed at promoting safe sleep (SS) practices and breastfeeding (BF) within a population of pregnant Supplemental Nutrition Program for Women, Infants, and Children (WIC) clients.

The study will randomize 2,000 pregnant women, when they reach 34 weeks gestation, to one of four mHealth prenatal/postnatal messaging combinations of safe sleep and breastfeeding practices.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Infant sleep position in the previous two weeks
Time Frame: Between 2 and 6 months
An investigator-developed maternal survey will be used to assess infant's sleep position during the previous two weeks with categorical responses of back, stomach, side, and other. We will examine: A) Usual position; B) Exclusive use of supine position
Between 2 and 6 months
Infant sleep location in the previous two weeks
Time Frame: Between 2 and 6 months
An investigator-developed maternal survey will be used to assess the infant's sleep location during the previous two weeks with categorical responses of room sharing without bed sharing, room sharing with bed sharing, no room sharing and no bed sharing. We will examine: A) Usual location; B) Exclusive location of room sharing without bedsharing
Between 2 and 6 months
Any Soft bedding use in the previous two weeks
Time Frame: Between 2 and 6 months
An investigator-developed maternal survey will be used to assess soft bedding placed in and around the infant (while sleeping) during the previous two weeks with categorical responses of Yes or No.
Between 2 and 6 months
Any Pacifier use in the previous two weeks
Time Frame: Between 2 and 6 months
An investigator-developed maternal survey will be used to assess the infant's pacifier use during the previous two weeks with categorical responses of Yes or No.
Between 2 and 6 months
Infant feeding in the previous two weeks
Time Frame: Between 2 and 6 months
An investigator-developed maternal survey will be used to assess whether the infant was breast fed during the previous two weeks with categorical responses of exclusively breast fed, partially breast fed, or not breast fed. We will examine: A) Any breast milk feeding; B) Exclusive breast milk feeding
Between 2 and 6 months

Between 36 weeks gestational age and birth
Planned infant sleep position after birth of baby
Time Frame: Between 36 weeks gestational age and birth.
The impact of the only the prenatal intervention on planned infant sleep position after birth of baby obtained through maternal survey responses on the prenatal survey
Between 36 weeks gestational age and birth.

The impact of the only the prenatal intervention on planned infant sleep location after birth of baby obtained through maternal survey responses on the prenatal survey
Between 36 weeks gestational age and birth.
Planned breast milk feeding after birth of baby
Time Frame: Between 36 weeks gestational age and birth.
The impact of the only the prenatal intervention on planned breast milk feeding after birth of baby obtained through maternal survey responses on the prenatal survey
Between 36 weeks gestational age and birth.
Planned duration of breast milk feeding after birth of baby
Time Frame: Between 36 weeks gestational age and birth
An investigator-developed maternal prenatal survey will be used to assess planned duration of breast milk feeding after birth of baby obtained through maternal survey responses on the prenatal survey
Between 36 weeks gestational age and birth
Days from postnatal randomization to first report of not exclusively in the supine sleep position
Time Frame: Weekly until the infant is 26 weeks of age.
The number of days after postnatal randomization when supine sleep position is stopped will be assessed by maternal response to weekly text messages about sleep position during the past week.
Weekly until the infant is 26 weeks of age.
Days from postnatal randomization to first report of not exclusively room sharing without bed sharing
Time Frame: Weekly until the infant is 26 weeks of age.
The number of days after postnatal randomization when sleep location of room sharing without bed sharing stopped will be assessed by maternal response to weekly text messages about sleep location during the past week.
Weekly until the infant is 26 weeks of age.
Days from postnatal randomization to first report of using any soft bedding
Time Frame: Weekly until the infant is 26 weeks of age.
The number of days after postnatal randomization when soft bedding use starts will be assessed by maternal response to weekly text messages about type of bedding during the past week.
Weekly until the infant is 26 weeks of age.
Days from postnatal randomization to first report of not receiving exclusively Breast Milk feedings
Time Frame: Weekly until the infant is 26 weeks of age.
The days from postnatal randomization when breast feeding changed will be assessed by maternal response to weekly text messages about type of breast feeding categorized as either exclusive, partial or no breast milk during the past week.
Weekly until the infant is 26 weeks of age.
Days from postnatal randomization to first report of not receiving any Breast Milk feedings
Time Frame: Weekly until the infant is 26 weeks of age.
