Mongolia health situation: based on the Global Burden of Disease Study 2019.

BACKGROUND: Over the past few decades, economic, political, and social changes have directly and indirectly affected the health of the Mongolian population. To date, no comprehensive analysis has been conducted on the burden of diseases in this country. Thus, we aimed to describe the leading causes of death and disabling conditions and their trends between 1990 and 2019 in the Mongolian population. METHODS: We used the data from the Global Burden of Disease (GBD) 2019 study. In the current study, we examined life expectancy at birth, healthy life expectancy, the 20 leading causes of death, years of life lost (YLLs), years lived with disability (YLDs), disability-adjusted-life-years (DALYs), and the contribution of major risk factors to DALYs in Mongolia. FINDINGS: The life expectancy at birth in Mongolia has gradually increased since 1995 and reached 63.8 years for men and 72.7 for women in 2019. The highest increase in the age-standardised death rate between 1990 and 2019 occurred in alcohol use disorders (628.6%; 95% UI 10.0-1109.6) among men, and in liver cancer (129.1%; UI 65.3-222.4) among women. Ischaemic heart disease and stroke showed the highest rates of death, YLLs, and DALYs among both men and women. In 2019, the highest age-standardised rates of DALYs were attributable to high systolic blood pressure and dietary risks. INTERPRETATION: Although Mongolia saw substantial improvements across many communicable diseases, maternal and neonatal disorders, and under-5 mortality between 1990 and 2019, non-communicable diseases remained leading causes of mortality. The mortality from the most preventable causes such as injury, alcohol use, and dietary risks remain substantially high, suggesting that individual and social efforts are needed to tackle these diseases. Our analyses will support the development of policy priorities and action plans in multiple sectors to improve the overall health of the Mongolian population.

Potential years of life lost (PYLL) caused by asbestos-related diseases in the world.

BACKGROUND: We applied the well-established, but rather under-utilized, indicator of Potential Years of Life Lost (PYLL) to estimate the global burden of mesothelioma and asbestosis. METHODS: We analyzed all deaths caused by mesothelioma and asbestosis that were reported by 82 and 55 countries, respectively, to the World Health Organization (WHO) from 1994 to 2010. RESULTS: The 128,015 and 13,885 persons who died of mesothelioma and asbestosis, potentially lost a total of 2.18 million and 180,000 years of life (PYLL), or, an annual average PYLL of 201,000 years and 17,000 years, respectively. The average PYLL per decedent were 17.0 and 13.0 years for mesothelioma and asbestosis, respectively. CONCLUSIONS: The current burden of asbestos-related diseases (ARDs) in terms of PYLL is substantial. The future burden of ARDs can be eliminated by stopping the use of asbestos.

Global mesothelioma deaths reported to the World Health Organization between 1994 and 2008.

OBJECTIVE: To carry out a descriptive analysis of mesothelioma deaths reported worldwide between 1994 and 2008. METHODS: We extracted data on mesothelioma deaths reported to the World Health Organization mortality database since 1994, when the disease was first recorded. We also sought information from other English-language sources. Crude and age-adjusted mortality rates were calculated and mortality trends were assessed from the annual percentage change in the age-adjusted mortality rate. FINDINGS: In total, 92,253 mesothelioma deaths were reported by 83 countries. Crude and age-adjusted mortality rates were 6.2 and 4.9 per million population, respectively. The age-adjusted mortality rate increased by 5.37% per year and consequently more than doubled during the study period. The mean age at death was 70 years and the male-to-female ratio was 3.6:1. The disease distribution by anatomical site was: pleura, 41.3%; peritoneum, 4.5%; pericardium, 0.3%; and unspecified sites, 43.1%. The geographical distribution of deaths was skewed towards high-income countries: the United States of America reported the highest number, while over 50% of all deaths occurred in Europe. In contrast, less than 12% occurred in middle- and low-income countries. The overall trend in the age-adjusted mortality rate was increasing in Europe and Japan but decreasing in the United States. CONCLUSION: The number of mesothelioma deaths reported and the number of countries reporting deaths increased during the study period, probably due to better disease recognition and an increase in incidence. The different time trends observed between countries may be an early indication that the disease burden is slowly shifting towards those that have used asbestos more recently.

Asbestos use and asbestos-related diseases in Asia: past, present and future.

BACKGROUND AND OBJECTIVE: Although there are growing concerns about the global epidemic of asbestos-related diseases (ARD), the current status of asbestos use and ARD in Asia is elusive. We conducted a descriptive analysis of available data on asbestos use and ARD to characterize the current situation in Asia. METHODS: We used descriptive indicators of per capita asbestos use (kilograms per capita per year) and age-adjusted mortality rates (AAMR, persons per million population per year) by country and for the region, with reference to the world. RESULTS: The proportion of global asbestos use attributed to Asia has been steadily increasing over the years from 14% (1920-1970) to 33% (1971-2000) to 64% (2001-2007). This increase has been reflected in the absolute level of per capita use across a wide range of countries. In contrast, 12 882 ARD deaths have been recorded cumulatively in Asia, which is equivalent to only 13% of the cumulative number of ARD deaths in the world during the same period. The highest AAMR were recorded in Cyprus (4.8), Israel (3.7) and Japan (3.3), all of which have banned asbestos use. CONCLUSIONS: There is a paucity of information concerning the current situation of ARD in Asia. The marked increase in asbestos use in Asia since 1970, however, is likely to trigger a surge of ARD in the immediate decades ahead.

Association between early essential newborn care and breastfeeding outcomes in eight countries in Asia and the Pacific: a cross-sectional observational -study.

OBJECTIVE: To explore the association between early essential newborn care (EENC) policy, practice and environmental interventions and breastfeeding outcomes. DESIGN: Cross-sectional observational study. SETTING: 150 national, provincial and district hospitals implementing EENC in eight countries in East Asia and the Pacific. PARTICIPANTS: 1383 maternal interviews, chart reviews and environmental assessments during 2016 and 2017. MAIN OUTCOME MEASURES: Exclusive breastfeeding (EBF), that is, feeding only breastmilk without other food or fluids since birth and before discharge, and, early breastfeeding initiation, that is, during skin-to-skin contact (SSC) with the mother without separation. RESULTS: Fifty-nine per cent of newborns initiated breastfeeding early and 83.5% were EBF. Duration of SSC showed a strong dose-response relationship with early breastfeeding initiation. SSC of at least 90 min was associated with 368.81 (95% CI 88.76 to 1532.38, p<0.001) times higher early breastfeeding. EBF was significantly associated with SSC duration of 30-59 min (OR 3.54, 95% CI 1.88 to 6.66, p<0.001), 60-89 min (OR 5.61, 95% CI 2.51 to 12.58, p<0.001) and at least 90 min (OR 3.78, 95% CI 2.12 to 6.74, p<0.001) regardless of delivery mode. Non-supine position (OR 2.80, 95% CI 1.90 to 4.11, p<0.001), rooming-in (OR 5.85, 95% CI 3.46 to 9.88, p<0.001), hospital breastfeeding policies (OR 2.82, 95% CI 1.97 to 4.02, p<0.001), quality improvement mechanisms (OR 1.63, 95% CI 1.07 to 2.49, p=0.02) and no formula products (OR 17.50, 95% CI 5.92 to 51.74, p<0.001) were associated with EBF. CONCLUSION: EENC policy, practice and environmental interventions were associated with breastfeeding outcomes. To maximise the likelihood of early and EBF, newborns, regardless of delivery mode, should receive immediate and uninterrupted SSC for at least 90 min.

Global magnitude of reported and unreported mesothelioma.

BACKGROUND: Little is known about the global magnitude of mesothelioma. In particular, many developing countries, including some with extensive historical use of asbestos, do not report mesothelioma. OBJECTIVES: We estimated the global magnitude of mesothelioma accounting for reported and unreported cases. METHODS: For all countries with available data on mesothelioma frequency and asbestos use (n=56), we calculated the 15-year cumulative number of mesotheliomas during 1994-2008 from data available for fewer years and assessed its relationship with levels of cumulative asbestos use during 1920-1970. We used this relationship to predict the number of unreported mesotheliomas in countries for which no information on mesothelioma is available but which have recorded asbestos use (n=33). RESULTS: Within the group of 56 countries with data on mesothelioma occurrence and asbestos use, the 15-year cumulative number of mesothelioma was approximately 174,300. There was a statistically significant positive linear relation between the log-transformed national cumulative mesothelioma numbers and the log-transformed cumulative asbestos use (adjusted R(2)=0.83, p<0.0001). Extrapolated to the group of 33 countries without reported mesothelioma, a total of approximately 38,900 (95% confidence interval, 36,700-41,100) mesothelioma cases were estimated to have occurred in the 15-year period (1994-2008). CONCLUSIONS: We estimate conservatively that, globally, one mesothelioma case has been overlooked for every four to five reported cases. Because our estimation is based on asbestos use until 1970, the many countries that increased asbestos use since then should anticipate a higher disease burden in the immediate decades ahead.

Cancer risk among Japanese chromium platers, 1976-2003.

OBJECTIVE: The aim of our prospective cohort study was to assess cancer mortality risks among chromium platers. METHODS: The cohort comprised 1193 male platers (626 with exposure to chromium, the remainder with no exposure) with a follow-up period of 27 years (1 October 1976 to 31 December 2003). Mortality risk was assessed by the standardized mortality rate (SMR) with reference to the national population. RESULTS: Lung cancer mortality was elevated only in the chromium plater subgroup, with borderline statistical significance [SMR=1.46, observations (Obs)=28, 95% confidence interval (95% CI) 0.98-2.04]. The chromium plater subgroup also showed elevated mortality risks for brain tumor (SMR=9.14, Obs=3, 95% CI 1.81-22.09) and malignant lymphoma (SMR=2.84, Obs=6, 95% CI 1.05-5.51). Risks were particularly elevated for lung cancer (SMR=1.59, Obs=23, 95% CI 1.01-2.38) and malignant lymphoma (SMR=3.80, Obs=6, 95% CI 1.39-8.29) among those with initial chromium exposure prior to 1970. CONCLUSIONS: In Japan, occupational exposure to chromium through work as a chromium plater is a risk factor for lung cancer, especially for platers working prior to 1970. Occupational chromium exposure may also increase the risk of brain tumor and malignant lymphoma.

National use of asbestos in relation to economic development.

BACKGROUND: National disparities in asbestos use will likely lead to an unequal burden of asbestos diseases. OBJECTIVES: As economic status may be linked to asbestos use, we assessed, globally, the relationship between indicators of national economic development and asbestos use. METHODS: For the 135 countries that have ever used asbestos, per capita asbestos use (kilograms per capita per year) was compared with per capita gross domestic product (GDP) in 1990 Geary-Khamis dollars (GKD) for the period 1920-2003. Countries were grouped into three income levels (high, middle, and low) that were adapted from the 2003 World Bank categories. RESULTS: The historical pattern of asbestos use followed the environmental Kuznets curve in which use by high-income countries peaked when incomes attained 10,000-15,000 GKD and essentially ceased at income levels over 20,000 GKD. Currently, middle- and low-income countries are increasing their use of asbestos, closely following the paths once traced by higher income countries. CONCLUSIONS: Developing countries have the opportunity to eliminate asbestos use sooner than high-income countries and thus reduce the future burden of asbestos diseases.
