Prevalence of and factors associated with various level of body weight among Inner Mongolia medical students in China

Background: To date no study on the body weight of medical students in Inner Mongolia has been carried out. The aim of the present study was to determine the prevalence of and factors associated with various body weight levels, and the physical health status associated with body weight levels among medical students attending the Inner Mongolia Medical College of China in 2011. Methods: Data on participant characteristics came from basic information contained in the school database. Students’ body weight was categorized using standard height and weight and physical health status using the college student physical health standard. Factors associated with various level of body weight were identified using multinomial logistic regression analysis. Results: The sample comprised 2060 males and 5096 females. The appropriate body weight prevalence among the students was 51.7%. The prevalence of being overweight or obese was 5.8 and 8.5%, respecttively, higher compared to the typical prevalence among college students in China. Both male and female students in the 24-28-years age group had the lowest appropriate weight percentage and the highest obesity percentage among all the age groups. For female medical students, the prevalence of obesity for students studying in Clinical Medicine was higher than for other faculties. Multinomial logistic regression analysis of male students showed that lowest year of education (year 1) was a protective factor in regard to appropriate weight. For both male and female medical students, the obese group had the highest proportion of poor physical health status compared to other categories of body weight and the proportion with excellent physiccal health status constituted < 1% for males and 0% for females. Conclusions: School administrators should encourage medical students to actively participate in body weight training and education to improve attitudes toward inappropriate body weight, to increase protective factors, and reduce the risk factors for inappropriate body weight.

Evaluation of the ischemic risk in triple-vessel artery patients undergoing stent implantation

Objective Coronary artery disease(CAD) is a global problem.Every year, there was millions of patients suffered from CAD. With the fast development of coronary revascularization therapy, the mortality has decreased dramatically, while there still some forts needed to be conquered, such as multi-vessel coronary artery disease(MVD).

Comparison of breakfast consumption in rural and urban among Inner Mongolia Medical University students

Objective: The aim of current study was to investigate breakfast consumption between rural and urban among Inner Mongolia Medical University students, China. Method: From December 2010 to January 2011, a cross-sectional survey was conducted among medical students in the Inner Mongolia Medical University using a self-administered questionnaire. X2 was used to identify the differences between rural and urban. Result: The prevalence of breakfast consumption was 70.95%. The prevalence of breakfast in rural was higher than that in urban (72.09% vs. 69.78%). Breakfast consumption prevalence among male students in rural was higher 7.4% than those of students in urban. Students in Mongolian ethnic in rural were more likely to eat breakfast than Mongolian students in urban. The prevalence of breakfast decreases with grade increase both urban and rural. Students with good physical condition were more likely to eat breakfast compared with students with poor physical condition. Conclusion: The prevalence of regular breakfast consumption in rural was higher than that in urban. However, the prevalence of eating breakfast declined faster in rural than that in urban. Our study findings could help health care professionals develop targeted interventions designed to increase breakfast consumption.

Cancer mortality in Inner Mongolia of China, 2008-2010

Objective: The aim of our study was to determine the status of the common cancer in Inner Mongolia of China. Methods: We obtained data from the Centers for Disease Control in the Inner Mongolia from five monitoring points of DRS in Inner Mongolia from 2008 to 2010. We calculated the crude mortality, the proportion of all cause of death during the three years, further calculated cancer mortality, the proportion of cancer death and PYLL by genders. Results: During the period 2008-2010, the crude mortality of all cause of death is 518.02 per million in Inner Mongolia. As the second most common cause of death, the mortality dying from cancer is 127.11 per million, accounting for over one fifth of all deaths. Among all deaths from cancer, the lung cancer had the highest mortality rates (46.25 per million in males and 17.95 per million in females) and PYLL (0.72 in males and 0.41 in females), followed by the liver cancer (23.76 per million) and the gastric cancer (16.15 per million). The female breast cancer is the fourth leading cancer from mortality and PYLL for 7.65 per million and 0.17. Conclusion: Our analysis determined the severity of cancer death in Inner Mongolia of China from 2008 to 2010.Our study found that the cancer mortality in Inner Mongolia is lower than Chinese average level and most west countries, higher than some Africa countries. Our results will guide future cancer control strategies in Inner Mongolia of China.

A Model of Aircraft Support Concept Evaluation Based on DEA and PCA

With the vigorous development of equipment manufacturing industry in China, higher requirements to the equipment supportability are put forward. How to evaluate the supportability of equipments(especially the aviation equipment-aircraft) objectively and correctly is the problem to be solved in the development of aviation equipments construction, demonstration and battle application.Aimed at the needs of the supportability analysis of complex equipment systems-aircraft, a model of aircraft support concept evaluation based on DEA(data envelopment analysis) and PCA(principal component analysis) is proposed. The model is used to evaluate a certain aircraft support concept.The process and the results of evaluation show that proposed model is feasible and effective. The model is suitable for advanced aircraft support concept evaluation. The feasibility and effectiveness of the proposed model is verified by the analysis of the evaluation results. This method is applicable to the evaluation of aircraft support concepts.
