Association Between Infertility and Sickness Presenteeism Among Japanese Workers: A Cross-Sectional Study.

OBJECTIVE We examined the association between infertility status and sickness presenteeism among Japanese workers.

METHODS We conducted a cross-sectional analysis using data from the W2S-Ohpm Study. Participants were 16,685 workers aged 20-49 years. Infertility status was categorized as no infertility, treated infertility, or untreated infertility. Sickness presenteeism was measured by the number of days worked despite poor health. Negative binomial regression estimated adjusted incidence rate ratios (IRRs).

RESULTS Among men, treated and untreated infertility were associated with higher sickness presenteeism (treated: IRR=1.96; 95% CI: 1.24-3.11; untreated: IRR=2.12; 95% CI: 1.49-3.02). Among women, untreated infertility was significantly associated with increased presenteeism (IRR=1.47; 95% CI: 1.12-1.94).

CONCLUSIONS Infertility status was associated with sickness presenteeism among Japanese workers.
