Brief summary

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).

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.

Interventions

BEHAVIORALPrenatal Safe Sleep Mobile Health (mHealth) Messaging

Participants will receive prenatal Safe Sleep mHealth messaging starting at 34 weeks gestation until birth of their baby.

BEHAVIORALPrenatal Breastfeeding Mobile Health (mHealth) Messaging

Participants will receive prenatal Breastfeeding mHealth messaging starting at 34 weeks gestation until birth of their baby.

BEHAVIORALPostnatal Safe Sleep Mobile Health (mHealth) Messaging

Upon birth of baby, participants will begin receiving postnatal Safe Sleep mHealth messaging for a two month period.

BEHAVIORALPostnatal Breastfeeding Mobile Health (mHealth) Messaging

Upon birth of baby, participants will begin receiving postnatal Breastfeeding mHealth messaging for a two month period.

Intervention model description

The study will utilize a two-stage randomization approach in which pregnant women are randomly assigned to one of the two prenatal interventions (infant sleep practices messaging vs. infant feeding messaging) and then, at the time of birth ascertainment, randomization to one of two postnatal interventions (infant sleep practice messaging vs. infant feeding messaging). This will result in a classic 2 x 2 design where approximately 25% of participants will have been assigned to each of the four possible combinations of interventions (1 - prenatal sleep practices/ postnatal sleep practices; 2 - prenatal sleep practices/postnatal feeding practices; 3 - prenatal feeding practices/postnatal sleep practices; 4 - prenatal feeding practices/postnatal feeding practices).

Design outcomes

Primary

MeasureTime frameDescription
Number of Infants With no Soft Bedding Use in the Previous Two WeeksBetween 2 and 6 months following postnatal randomization, on average 67.7 daysAn 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.
Number of Infants Usually Sleeping Supine in the Previous Two WeeksBetween 2 and 6 months following postnatal randomization, on average 67.7 daysAn investigator-developed maternal survey will be used to assess infant's sleep position during the previous two weeks with categorical responses of supine (back), prone (stomach), side, and other.
Number of Infants Usually Room Sharing Without Bedsharing in the Previous Two WeeksBetween 2 and 6 months following postnatal randomization, on average 67.7 daysAn 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.
Number of Infants With Any Breastmilk Feeding in the Previous Two WeeksBetween 2 and 6 months following postnatal randomization, on average 67.7 daysAn 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.
Number of Infants With Pacifier Use in the Previous Two WeeksBetween 2 and 6 months following postnatal randomization, on average 67.7 daysAn 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.

Participant flow

Recruitment details

303 of the 2093 enrolled were not randomized prenatally due to: participant choice (165), study ended (56), pregnancy loss (26), delivery \<34 wks (17), contraindications (17), not pregnant (15), other (7). Infants were not considered to be enrolled.

Pre-assignment details

There was a 2- step randomization process- prenatally to 2 arms (n=1790, 897 randomized to prenatal safe sleep/SS and 893 randomized to prenatal breastfeeding/BF) and postnatally to 4 arms (n=1775). 15 of the 1790 randomized prenatally were not randomized postnatally- 7 of the 897 randomized to safe sleep/SS due to: participant choice (6), pregnancy loss (1), and 8 of the 893 randomized to breastfeeding/BF due to: participant choice (6), changed contact (1), pregnancy loss (1).
