Funded by the National Health and Medical Research Council of Australia and implemented by International Centre for Reproductive Health–Kenya (ICRHK), the WHISPER/SHOUT Clinical Trial was conducted in Mombasa County.

The study aimed to improve the health and well-being of female sex workers in resource-constrained settings by evaluating the effectiveness of two mobile phone delivered interventions:

• WHISPER, designed to prevent unintended pregnancies and improve sexual and reproductive health (SRH); and
• SHOUT, focused on improving nutritional health outcomes.

Impact
Through this innovative digital health trial, ICRHK:

• Leveraged mobile technologyto reach female sex workers with tailored, accessible health information and behavioral nudges.
• Assessed the effectivenessof mobile-based SRH interventions in reducing unintended pregnancies compared to nutrition-focused interventions.
• Evaluated improvements in nutritional outcomesamong participants receiving health messages on diet and wellbeing.
• Generated evidenceon the feasibility and impact of SMS-based interventions to address intersecting SRH and nutrition challenges among vulnerable populations.
• Contributed to scalable modelsfor using mobile health tools to enhance women’s health outcomes in low-resource urban contexts.
