This single-blind randomized controlled trial evaluated the effectiveness of a digital health education program delivered through WhatsApp in improving the quality of life of women with polycystic ovary syndrome (PCOS). Seventy women diagnosed with PCOS were enrolled from selected gynecology clinics in Imo State, Nigeria, and allocated to either an intervention group or a routine care control group. The intervention consisted of a four-week digital education program including 30 evidence-based educational messages. Quality of life was measured using the Polycystic Ovary Syndrome Quality of Life Questionnaire (PCOSQ) at baseline and one month after completion of the intervention.
