BackgroundPresenteeism, defined as attending work while ill, is a growing concern among healthcare professionals due to its impact on well-being, work function, and the quality of care. Despite extensive global research, evidence from Mongolia remains limited, where workforce shortages and systemic constraints uniquely shape presenteeism. We examined factors associated with presenteeism among Mongolian healthcare professionals.MethodsThis study used an explanatory sequential mixed-method design. The quantitative phase consisted of a cross-sectional online survey of physicians and nurses at three referral-level state hospitals, who were selected by convenience sampling. The qualitative phase consisted of semi-structured interviews with clinician managers, selected through purposeful sampling until thematic saturation was reached. Data were thematically analyzed, and the findings were integrated through triangulation.ResultsA total of 465 survey respondents (physicians and nurses) participated in the quantitative phase, of which 64.5% reported presenteeism. The factors significantly associated with presenteeism were psycho-physical health complaints (AOR = 4.51, p < 0.001), coworkers' support (AOR = 2.38, p < 0.001), and workload (AOR = 2.08, p < 0.001). Qualitative analysis of 14 interviews with clinician managers identified five interrelated themes: inadequate occupational health policy, shortcomings of occupational infrastructure, staff shortages and heavy workloads, informal workplace practices and professional norms, and unaddressed health burdens. Integration of quantitative and qualitative findings indicates that these associations are shaped by underlying organizational and structural conditions. Qualitative data explain how heavy workload, staff shortages, and informal workplace norms compel healthcare professionals to work despite illness, while strained coworker relationships reflect peer pressure and team-based expectations. Taken together, similar to the existing global literature, the results reveal that structural and organizational challenges, rather than individual health-related behaviors, are the primary drivers of presenteeism in this context.ConclusionsThe findings suggest that addressing presenteeism among healthcare professionals in Mongolia and similar low-resource settings requires coordinated national efforts targeting workplace conditions, organizational support, and occupational health policies to promote workforce well-being.

PurposeTo identify the socio-demographic determinants and temporal changes of suicide attempts and deaths in Mongolia.MethodsNational injury surveillance and population data of Mongolia (2016-2023) were used to calculate annual rates of suicide attempts and deaths per 10,000 population with stratification by age, sex, and geographic region. Temporal changes were assessed by calculation of annual percentage changes (APCs). For education and occupation, relative count ratios (CRs) were used to compare the distribution of cases across categories.ResultsThere were 5,846 suicide attempts and 3,266 suicide deaths during the study period. Ulaanbaatar had the highest rate of suicide attempts (3.6/10,000), but rural areas and Ulaanbaatar had similar rates of suicide deaths (1.2 vs. 1.3/10,000). Suicide deaths rose sharply from 2016 to 2023, particularly among rural females (APC = 33.7) and rural males (APC = 36.8). Notably, individuals with only primary or middle school education had the highest CRs for suicide attempts (Ulaanbaatar CR = 6.4, rural CR = 4.9) and suicide deaths (Ulaanbaatar CR = 6.7, rural CR = 6.3). Geographical disparities were notable among rural areas, and Khuvsgul Province (1.9/10,000) had the highest rate of suicide deaths.ConclusionBetween 2016 and 2023, Mongolia experienced a steep increase in rural suicide deaths. Although Ulaanbaatar had a higher rate of suicide attempts, rural areas had a higher rate of suicide deaths. Age, sex, education, and area of residence had pronounced associations with these outcomes. Two of the groups with the highest observed burden were young adults and rural males; conversely, those who completed higher education showed the lowest observed frequency of events.
