Short message service communication improves exclusive breastfeeding and early postpartum contraception in a low- to middle-income country setting: a randomised trial

Abstract

Objective: To assess the effect of short message service (SMS) communication on facility delivery, exclusive breastfeeding (EBF), and contraceptive use.

Design: Mobile WACh was a three-arm unblinded individually randomised controlled trial.

Setting: A public sector maternal child health (MCH) clinic in Nairobi, Kenya.

Population: Three hundred women attending antenatal care were randomised, 100 to each arm, and followed for 24 weeks postpartum. Pregnant women, at least 14 years old with access to a mobile phone and able to read SMS were eligible for participation.

Methods: Women were randomised (1:1:1) to receive one-way SMS versus two-way SMS with a nurse versus control. Weekly SMS content was tailored for maternal characteristics and pregnancy or postpartum timing.

Main outcome measures: Facility delivery, EBF, and contraceptive use were compared separately between each intervention arm and the control arm by Kaplan-Meier analysis and chi-square tests using intent-to-treat analyses.

Results: The overall facility delivery rate was high (98%) and did not differ by arm. Compared with controls, probability of EBF was higher in the one-way SMS arm at 10 and 16 weeks, and in the two-way SMS arm at 10, 16, and 24 weeks (P < 0.005 for all). Contraceptive use was significantly higher in both intervention arms by 16 weeks (one-way SMS: 72% and two-way SMS: 73%; P = 0.03 and P = 0.02 versus 57% control, respectively); however, this difference was not significant when correcting for multiple comparisons.

Conclusion: One-way and two-way SMS improved EBF practices and early contraceptive use. Two-way SMS had an added benefit on sustained EBF, providing evidence that SMS messaging influences uptake of interventions that improve maternal and neonatal health.

Tweetable abstract: The Mobile WACh RCT demonstrates that SMS improved practice of exclusive breastfeeding and early postpartum contraception.
