Evening chronotype is linked to acquired premature ejaculation (APE) severity, with health-promoting lifestyle (HPL) mediating this connection. Illness perception further influences these relationships in men with APE.
Area of Science:
- Male sexual health
- Chronobiology
- Behavioral science
Background:
- Acquired premature ejaculation (APE) is a common male sexual dysfunction impacting quality of life.
- The etiology of APE is not fully understood, despite identified risk factors.
Purpose of the Study:
- To investigate the association between chronotype (an individual's natural inclination towards specific sleep-and-wake times) and APE.
- To examine the mediating role of health-promoting lifestyle (HPL) and the moderating effect of illness perception in the chronotype-APE relationship.
Main Methods:
- A study involving 516 men with APE and 495 healthy controls.
- Participants completed validated questionnaires assessing APE, chronotype, HPL, and illness perception.
- Moderated mediation analysis was employed to explore underlying mechanisms in APE patients.
Main Results:
- An evening chronotype was significantly associated with both the presence and increased severity of APE.
- Health-promoting lifestyle (HPL) partially mediated the relationship between chronotype and APE severity.
- Illness perception moderated the associations between chronotype and HPL, and between HPL and APE.
Conclusions:
- Chronotype, HPL, and illness perception are significant factors in understanding and potentially managing APE.
- Integrating these factors into clinical assessments may enhance the understanding of ejaculatory control in men with APE.
