Mother's Milk Messaging™: trial evaluation of app and texting for breastfeeding support

A Pilot Breastfeeding-Supportive Texting Program for African American and Black Mothers

Background: Exclusive breastfeeding is recommended through age 6 months, and 24.9% of all U.S. mothers, but only 19.8% of African American or Black (AA/B) mothers, achieved this goal (2020). Smartphone technology, specifically short message service (SMS or texting), may provide a strategy to reach and engage AA/B women who otherwise face barriers related to racism in accessing breastfeeding resources. Unfortunately, few mobile health applications are designed for AA/B women. Methods: We created a culturally sensitive breastfeeding promotion and support text message library that begins at 28 weeks prenatally and continues through 10 weeks postpartum. We tested feasibility and acceptability with a proof-of-concept (POC) trial that enrolled 20 AA/B women, and we tested content and perceived usefulness with a pilot study that enrolled 28 AA/B women. Results: In the POC trial, 95% of participants received all messages, demonstrating feasibility, and none requested fewer or to stop messages, demonstrating acceptability. In the pilot, >85% of participants responded positively regarding the number and helpfulness of the texts received, and whether the information was needed. Using a validated measure for online content for parents, >70% of POC and pilot study participants found that the information was very relevant or relevant, completely understandable, taught them something new, and "will help me improve the health or well-being of my child." Conclusion: A new breastfeeding-supportive text messaging program intended for AA/B mothers appears feasible, acceptable, informative, and relevant. This is the first breastfeeding text messaging application of which we are aware that is tailored for the AA/B population.

Text messaging interventions for breastfeeding outcomes: A systematic review and meta-analysis

BACKGROUND

Given the health benefits of breastfeeding for infants and mothers, breastfeeding has become a significant public health issue. The global growth of mobile phone usage has created new options for breastfeeding promotion, including text messaging.

OBJECTIVE

We aimed to evaluate the efficacy of text messaging interventions on breastfeeding outcomes and to identify the efficacy moderators of such interventions.

METHODS

Ten electronic databases were searched from the inception of the databases to 5 July 2023. Studies were included if they used randomized controlled trials or quasi-experimental designs to evaluate the effect of text messaging interventions on breastfeeding outcomes. Two reviewers screened the included studies, assessed the risk of bias, and extracted the data. Pooled results were obtained by the random-effects model, and subgroup analyses were conducted on intervention characteristics to identify potential moderators. The protocol of this study was registered on PROSPERO (ID: CRD42022371311).

RESULTS

Sixteen studies were included. Text messaging interventions could improve the exclusive breastfeeding rate (at <3 months: OR = 2.04; 95 % CI: 1.60-2.60, P < 0.001; at 3-6 months: OR = 1.66; 95 % CI: 1.18-2.33, P = 0.004; at ≥6 months: OR = 2.13; 95 % CI: 1.47-3.08, P < 0.001), and the breastfeeding self-efficacy (SMD = 0.30, 95 % CI: 0.14-0.45, P < 0.001). Text messaging interventions that covered antenatal and postnatal periods, delivered weekly were most effective in improving the exclusive breastfeeding rate.

CONCLUSIONS

Text messaging interventions may improve breastfeeding practice compared with no or general health information. We suggest text messaging conducted from the pre- to postnatal periods in a weekly manner can effectively increase exclusive breastfeeding rates and breastfeeding self-efficacy. Further studies should investigate the relation between new theories (such as the health action process approach and the theory of message-framing) and efficacy of breastfeeding interventions, using text components.
