The association between shift work, shift work sleep disorders and premature ejaculation in male workers

Area of Science:

• Sleep Medicine
• Andrology
• Occupational Health

Background:

• Shift work and Shift Work Sleep Disorder (SWSD) are implicated in hormonal and neurotransmitter dysregulation.
• The precise impact of these conditions on the regulation of male ejaculation remains incompletely understood.

Purpose of the Study:

• To investigate the relationship between shift work, SWSD, and the prevalence of premature ejaculation (PE).
• To identify risk factors associated with PE in male workers experiencing shift work and sleep disturbances.

Main Methods:

• A cross-sectional survey of 1239 male workers in China assessed work schedules, sleep quality (using SWSD questionnaire), erectile function (IIEF-5), and ejaculatory control (PEDT).
• Univariate and multivariate linear regression analyses identified risk factors for PE, with confounders controlled via multiple regression models.

Main Results:

• Shift work (β 1.58) and SWSD (β 2.86) were significantly associated with higher PEDT scores, indicating increased risk of PE.
• Identified risk factors for PE include: sleep deprivation (<6 hours), depression, anxiety, diabetes, hyperlipidemia, frequent alcohol consumption, and erectile dysfunction.
• A clinical prediction model for PE demonstrated significant efficacy.

Conclusions:

• Shift work and SWSD are significant risk factors that substantially increase the likelihood of premature ejaculation.
• The duration of shift work correlates with the magnitude of PE risk, underscoring the occupational impact on sexual health.
• Findings provide a foundation for risk assessment and preventative strategies concerning PE in shift-working populations.
