Mortality of urinary tract cancer in Inner Mongolia 2008- 2012

Effects of occupation on intracerebral hemorrhage-related deaths in Inner Mongolia

This study assessed the relationship between occupation and Intracerebral Hemorrhage-related deaths and compared the differences in ICH-related deaths rates between the eastern and midwestern regions of Inner Mongolia. We used the case-control method. Cases included Intracerebral Hemorrhage-related deaths that occurred from 2009 to 2012 in Inner Mongolia while controls included non-circulatory system disease deaths that occurred during the same period. Odds ratios (ORs) for Intracerebral Hemorrhage-related deaths were calculated using logistic regression analysis, estimated according to occupation, and adjusted for marital status and age. The Intracerebral Hemorrhage mortality rate in the eastern regions (125.19/100000) was nearly 3 times higher than that in the midwestern regions (45.31/100000). ORs for agriculture-livestock workers, service professionals and general workers, professional workers and senior officials were in descending order. The age-adjusted OR for Intracerebral Hemorrhage-related deaths was lowest in unmarried men senior officials (OR 0.37, 95% CI 0.14-0.99). The Intracerebral Hemorrhage mortality rate in the eastern regions was much higher than that of the midwestern regions, since about 90% of Intracerebral Hemorrhage-related deaths in the eastern regions were those of agriculture-livestock workers who has the largest labor intensity of any other occupation assessed.

The effect characteristics of temperature on stroke mortality in Inner Mongolia and globally

The current study investigated the correlation between stroke mortality and temperature. Monthly and seasonal variations in stroke mortality were plotted and daily stroke-related deaths were calculated. The lag times were calculated using the time series analysis. The correlation between stroke incidence and the diurnal temperature range (DTR) was analyzed using case-crossover analysis. Global stroke mortality was described in five latitudes. In the eastern region of Inner Mongolia, the stroke mortality was 174.18/105, about twice of that of the midwestern regions (87.07/105), and temperature was negatively correlated with stroke mortality. Mortality peaked in the winter and troughed in the summer (χ² = 13.634, P < 0.001). The days in which stroke-related deaths were greater than ten occurred between late October and early April. The effect of temperature on stroke incidence occurred during a lag time of 1 (P = 0.024) or 2 months (P = 0.039). A DTR over 13 °C was positively correlated (r = 0.95, P = 0.004) with stroke with a lag time of 1 day. The effect of temperature on stroke was shown to be the same for various populations. As the latitude increases, stroke mortality also increases with latitudes > 40°; the highest mortality was 188.05/105 at the highest latitude. Only in relatively cold regions as the temperature decreases does stroke mortality increase for various populations. Differences in the time lag as well as in the DTR lag and DTR critical point vary for both the temperature and region.

The gap in digestive organ cancers in Inner Mongolia, 2009-2012

Objective:

The aim of this study was to explore the characteristics of digestive organ cancer mortality and the potential years of life lost in Inner Mongolia, and to provide evidence for the prevention of digestive organ cancers.

Methods:

Using data from the Death Registry System from 2009 to 2012, we classified male and female cancer deaths according to the International Classification of Disease (10th revision). The mortality and potential years of life lost were calculated for digestive organ cancers in Inner Mongolia. The average years of life lost was calculated.

Results:

Digestive organ cancer mortality in Inner Mongolia was higher in men than in women. The potential years of life lost were also much higher in men than in women. Gallbladder cancer, pancreatic cancer, and colorectal, anus, and anal canal cancer were the most prominent contributors to mortality. Esophageal cancer was the most prominent contributor to potential years of life lost, and was the leading cause of average years of life lost in both sexes.

Conclusion:

Liver cancer and stomach cancer mortality and the potential years of life lost to liver and stomach cancer are demonstrably higher in Inner Mongolia. Although esophageal cancer mortality was not the highest of the digestive organ cancers, the average years of life lost to esophageal was the highest for both sexes, and it should therefore be targeted for prevention.
