This study aimed to examine the reproductive concerns and their influencing factors among adolescents and young adults with acute leukaemia and to explore the relationship between reproductive concerns and patients’ quality of life.

A cross-sectional study.

The haematology departments of four tertiary-level hospitals in Hunan province, China.

Convenience sampling method was used to recruit 233 adolescents and young adults with acute leukaemia, from June 2024 to December 2024.

The primary outcome was assessed using the Chinese version of the Reproductive Concerns After Cancer and the secondary outcome was measured by the 12-item Short Form Health Survey.

Adolescents and young adults with acute leukaemia had a mean reproductive concerns score of 55.57±7.57, a quality of life physical component summary (PCS) score of 38.54±8.58 and a mental component summary (MCS) score of 39.84±8.78.

Adolescents and young adults with acute leukaemia exhibited moderately high levels of reproductive concerns, particularly those who had no children, had a low education level, resided in rural areas, had a family history of acute leukaemia or had received fertility counselling. Therefore, we suggest that healthcare providers prioritise addressing reproductive concerns in high-risk patients by offering tailored, high-quality and continuous fertility counselling and psychological support. Strengthening these strategies can help alleviate reproductive concerns and improve both mental health and overall quality of life in this population.
