OBJECTIVE Even though postpartum morbidity continues to cause high disease burden in maternal morbidity and mortality across the globe, the literature pertaining to resultant productivity loss is scarce. Hence, the present study aimed at determining the productivity loss and associated cost of episodes of postpartum ill health. METHODS A cross sectional study was conducted in two Medical Offi...

This quantitative, descriptive, cross-sectional research aimed to determine the estimated productivity of health-related limitations at work in 129 nurses working in direct care delivery to critical and potentially critical patients. Instruments were applied for socio-demographic and functional characterization and for the evaluation of presenteeism (Work Limitations Questionnaire). Statistical...

INTRODUCTION Poor oral health is associated with lost hours at work or school, which may affect a person's productivity. The objective of our study was to estimate work or school hours lost to dental visits among adults aged 18 and older by the types of visits (emergency or unplanned; routine, planned, or orthodontic; or cosmetic) and to determine the factors associated with hours lost. METHO...
