ABSTRACT
<p><b>OBJECTIVE</b>To know about the status of hypertension among Mongolian and Han aged older than 55 years living in pastoral area of the Inner Mongolia Autonomous Region.</p><p><b>METHODS</b>Stratified sampling method was adopted and 9146 people aged 55 years or older were selected, blood pressure measurement and related information were collected, prevalence, awareness, treatment and control rates of hypertension were analyzed.</p><p><b>RESULTS</b>The hypertension crude prevalence rate of Mongolian and Han subjects was 54.10% (standardized prevalence rate was 53.93%), in which, the Mongolian and Han subjects crude hypertension prevalence rate was 52.96% and 54.73% respectively (standardized prevalence rate was 53.44% and 55.08% respectively), and there was no statistically significant (P = 0.104). Among the male gender, awareness rate, treatment rate and control rate of hypertension was 61.03%, 46.73% and 11.87% respectively. Among the female gender, awareness rate, treatment rate and control rate of hypertension was 67.58%, 56.55% and 14.03% respectively. Among Mongolian and Han subjects, difference of hypertension prevalence of different age groups was statistically significant (P values were 0.032 and 0.000), Among Mongolian subjects, difference of hypertension awareness of different age groups was statistically significant (P = 0.000). Among Han subjects, difference of hypertension awareness rates, treatment rates, and control rates of different age groups were statistically significant (P values were 0.000, 0.047 and 0.043).</p><p><b>CONCLUSION</b>Hypertension prevalence rate among Han and Mongolian people older than 55 years living in pastoral area of Inner Mongolia Autonomous Region is high while the awareness, treatment and control rates of hypertension are rather low.</p>

Objective To understand the epidemiological characteristics and distribution of mild cognitive impairment (MCI) in elderly populations from Mongolian and Han nationalities living in the pastoral areas of Inner Mongolia Autonomous Region of China.Methods According to the MCI clinical diagnostic criteria from Diagnostic and Statistical Manual of Mental Disorders 4th revised edition (DSM-Ⅳ ) by American Psychiatric Association,the individuals under study were at the age of 55 or over,with Mongolian or Han ethnicities and living in the pastoral area of Inner Mongolia.Results The crude MCI morbidity rates of Mongolian and Han of the study populations in the pastoral area of Inner Mongolia Autonomous Region of China was 19.48％ (1782/9146)and the standardization morbidity was 18.98％.The crude MCI morbidity rates of both Mongolian and Han cthnicities were 17.46％ (the standardization morbidity was 16.99％) and 20.60％ (the standardization morbidity was 19.98％ ),respectively.There showed a significant positive correlation between the crude morbidities and age,also significantly increasing with the latter.In the Mongolian population,the morbidity increased from 12.17％ at the age 55-59 to 27.78％ at 85 while in the Han population,the morbidity increased from 15.50％ at the age 55-59 to 23.53％ at 85.In both the populations of Mongolian and Han,there was a statistically difference found between the morbidities of MCI ( x2=13.229,P=0.000).The morbidity was higher in Hans than in the Mongolians.However,there was no statistically significant difference noticed between the morbidities of MCI in the Mongolian males and females ( x 2 =2.376,P =0.123 ).There was statistically significant difference found between the morbidities of MCI in the Han males and females,with females having higher risk than males (x2=24.470,P=0.000).Conclusion The morbidity of MCI in the elderly Mongolian and Han populations from the pastoral area of Inner Mongolia Autonomous Region of China was considered to be quite high and correlated to age and gender.
