INST’AJA: a co-designed Instagram campaign to promote sexual health education and behaviors in adolescent and young adult cancer survivors

Adolescents and young adults (AYA; aged 15-39 years) living with or beyond cancer experience persistent unmet needs in sexual health education, with 20%-50% reporting treatment-related sexual dysfunction.1 Despite high engagement with social media, digital oncology programs rarely address sexual health at scale. We conducted a pilot evaluation of INST’AJA, a co-designed Instagram campaign delivering medically validated sexual health educational content for AYA cancer survivors. Between October 24, 2024 and October 2, 2025, 12 short (<3 min) Instagram Reels were disseminated through 2 accounts with a combined reach exceeding 24 000 followers (ASSOCIATIONAIDA [22 700 followers]; JEUNE.CANCER [1749 followers]). Content addressed sexuality, mental health, contraception, fertility, and cancer surveillance. Campaign content was co-designed with 15 AYA participants and healthcare professionals using a Delphi-based prioritization approach. Candidate topics were generated from survivorship needs and AYA suggestions, then iteratively refined through consensus rounds to select 12 final themes. Scripts and final edits were reviewed by a multidisciplinary panel (oncology, sexology, psychology) to ensure medical accuracy and age-appropriate delivery. Ethical approval was obtained from a University Hospital Ethics Committee.
