Abstract
<p><strong>OBJECTIVE:</strong> This study aimed to assess the characteristics of anemia-related deaths and the relationship between socio-demographic status and mortality risk of anemia in Inner Mongolia from 2008 to 2012.</p><p><strong>METHODS:</strong> We obtained our data for 2008–2012 from the Death Registry System of Inner Mongolia. We calculated the mortality, percentage, and potential years of life lost (PYLL) of anemia in diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (DBDIM). We collected socio-demographic status of case and control, including marital status, education level, area of residence, and occupation. Logistic regression models were employed to analyze which factor has effect to mortality risk of anemia.</p><p><strong>RESULTS: </strong>The total mortality from anemia was 0.66/10<sup>5</sup>, and the mortality rates in male and female were 0.74/10<sup>5</sup> and 0.57/10<sup>5</sup>, respectively (χ<sup>2</sup> = 1.270, P = 0.260). No significant differences in the mortality of anemia were observed from 2008 to 2012 (χ<sup>2</sup> = 6.003, P = 0.199). In DBDIM approximately 80% of these deaths were caused by anemia. Among the various types of anemia, aplastic and other anemias (AOA) showed the highest PYLL and mortality. The age-specific mortality curve for anemia, which increased with age, is similar in both genders. Moreover, a high education level increased the mortality risk of anemia.</p><p><strong>CONCLUSION:</strong> Among the various types of anemia, AOA showed the highest PYLL and mortality, and the burden of premature death resulting from AOA is possibly more serious than other anemia. Moreover, high education level increased the mortality risk of anemia.</p>
Highlights
Anemia is a condition characterized by a low number of red blood cells or low oxygen-carrying capacity that insufficiently meets physiologic needs
Among the various types of anemia, AOA showed the highest potential years of life lost (PYLL) and mortality, and the burden of premature death resulting from AOA is possibly more serious than other anemia
We obtained the data for 2008–2012 from death certificates retrieved from the Death Registry System (DRS) of eight monitoring points, five of which were established by the Chinese Ministry of Health and three by the Center for Disease Control (CDC) of Inner Mongolia (Xin et al, 2014)
Summary
Anemia is a condition characterized by a low number of red blood cells or low oxygen-carrying capacity that insufficiently meets physiologic needs. This disorder varies by age, sex, altitude, smoking, and pregnancy status (WHO, 2015a). Anemia indicates both poor nutrition and poor health (World Health Organization and United Nations Children’s Fund, 2004) and is a public health problem affecting populations in both rich and poor countries (Bruno, Erin, Ines, & Mary, 2008). Up to 25% of older people in the United States and in other Western countries are anemic based on WHO criteria (Chalmers et al, 2012), indicating that anemia is highly prevalent in older people (Milward, 1999; Challand et al, 1990)
