Move and Play Programme: Perceptions of Paediatric Physiotherapists and Parents of Infants.

With significant advances in pediatric oncology, survival rates for childhood, adolescent, and young adult (CAYA) cancer have improved markedly over the past several decades., , , As a result, CAYA cancer survivors represent a growing population with complex and evolving health care needs. The focus of survivorship care and research has increasingly shifted to understanding and managing the long‐term and late effects of CAYA cancer and its treatment. For example, CAYA cancer survivors are at increased risk for a variety of late health problems, such as endocrine dysfunction, cardiovascular disease, and psychological distress., , , , , , , , Sexual health is a key component of overall well‐being and encompasses physical, emotional, mental, and social aspects of sexuality. Disruptions in sexual health may have lasting implications for quality of life, identity development, and intimate relationships, especially during the transition from adolescence to adulthood. CAYA cancer survivors may be particularly vulnerable to challenges in this domain due to both biological and psychosocial mechanisms. Cancer therapies can affect endocrine and reproductive function,, whereas the timing of diagnosis and treatment during critical developmental periods may disrupt psychosexual development., , , In addition, visible or perceived changes in physical appearance resulting from treatment, such as scarring or altered body morphology, can contribute to body image concerns and diminished self‐esteem, which in turn can affect the ability to initiate or maintain romantic and sexual relationships., , Previous research on sexual health, including the Childhood Cancer Survivor Study, the St. Jude Lifetime Cohort Study, and national cohorts such as the Dutch Childhood Cancer Survivor Study, has demonstrated impairments in sexual functioning and psychosexual development, , , , in CAYA cancer survivors. However, several knowledge gaps remain. First, much of the existing literature relies on cross‐sectional or single follow‐up assessments, limiting insight into how sexual health presents across survivorship. Second, although sexual functioning has been a central focus of prior studies, survivorship research has devoted comparatively less attention to behavioral outcomes, including sexual activity, contraceptive practices, and condom use, despite their direct implications for unintended pregnancy and sexually transmitted infection risk. Third, little evidence exists on how treatment‐related factors may influence sexual health behaviors in ways that can directly inform clinical decision‐making, including identifying subgroups of survivors who may require tailored counseling. A recent systematic review further highlights the limited availability of longitudinal and behaviorally oriented sexual health data in the CAYA cancer survivor population. Understanding sexual health behaviors in this population has direct implications for survivorship care, as these behaviors are modifiable and represent key targets for preventive counseling and intervention. The present study aims to examine sexual health outcomes among Canadian CAYA cancer survivors using repeated assessments collected as part of routine survivorship care. Specifically, we aim to describe the prevalence of sexual activity, concerns about sex life, and contraceptive and condom use across follow‐up assessments, and compare these outcomes with those of age‐matched individuals from the general Canadian population. Furthermore, we evaluate sociodemographic and cancer‐related predictors, including treatment intensity, to identify subgroups that may benefit from targeted sexual and reproductive health counseling.
