Mortality among female manual workers.

Area of Science:

• Occupational Health
• Epidemiology
• Public Health

Background:

• Female manual workers represent a significant demographic in the workforce.
• Understanding occupational health risks is crucial for targeted public health interventions.
• Previous studies have indicated potential health disparities among manual laborers.

Purpose of the Study:

• To investigate the mortality rates of female manual workers in the Reykjavík region.
• To compare the mortality of female manual workers against the general female population.
• To identify specific causes of death and risk factors associated with manual labor for women.

Main Methods:

• A retrospective cohort study design was employed.
• Mortality data were compared to the general female population using standardized mortality ratios (SMRs) and 95% confidence intervals (CIs).
• Participants included 18,878 women members of a manual workers' pension fund between 1970 and 1986, with analyses considering employment duration and latency periods.

Main Results:

• A healthy worker effect was observed in the total cohort.
• Standardized mortality ratios for all causes and cancers increased with employment duration up to 10 years, but decreased thereafter.
• Excess lung and bladder cancer, as well as accidents and suicides, were noted across various subcohorts, with higher mortality in those contributing to the fund more recently.

Conclusions:

• Mortality risks are elevated in specific subgroups of female manual workers.
• Longest-term employment was associated with lower mortality, contrasting with increased risks in shorter durations and more recent cohorts.
• The excess of suicides suggests potential psychological distress or reduced quality of life among these women, warranting further investigation.
