ABSTRACT
Objective To investigate the relationship between the quality of life and different frequency of sudden death in Yunnan unexplained sudden death disease area.Methods According to the stratified cluster sampling method,728 individuals were selected as the respondents in Heqing County,Eryuan County of Dali Bai Autonomous Prefecture,and in Dayao County of Chuxiong Yi Autonomous Prefecture.According to the random sampling,649 individuals were selected as the control in Yongping County,Dali Bai Autonomous Prefecture.Data of the quality of life (WHOQOL-BREF version) were collected through household surveys.Analysis method including ANOVA,Chi-squared test and multilinear regression were used.Results Compared with the control population,the household income of population in the diseased area was not significantly different statistically (x2 =7.052,P ＞ 0.05).But the differences in education level and chronic disease situation were statistically significant (x2 =35.727,9.810,all P ＜ 0.05).According to the frequency of the sudden death,from one to four,the total scores of the quality of life,the scores of the physiology domain,the scores of the psychological domain,the scores of the environmental domain and the scores of the social relations domain (1 time:54.30,13.74,14.43,11.21,14.91;2 times:54.75,13.86,14.65,11.12,15.10;3 times:52.40,13.21,13.76,11.00,14.41;4 times:49.21,12.15,12.54,9.87,14.64)were all lower than those of the control group (56.03,14.11,14.78,11.88 and 15.26),the differences between two groups were statistically significant (x2 =41.88,25.75,41.07,35.07,8.08,all P ＜ 0.05);the total scores and each domain score of the quality of life were negatively correlated with the frequency of sudden death (the multi-variables regression coefficient were as follows:-1.195,-0.341,-0.356,-0.314,and-0.185,all P ＜ 0.05).Conclusions The quality of life of those who have lived in Yunnan unexplained sudden death area is associated with the outbreak frequency of sudden death.Following increasing of the outbreak frequency of Yunnan unexplained sudden death,the quality of life of the population living in Yunnan unexplained sudden death area has decreased.
ABSTRACT
Objective To explore the correlations between the social support and the quality of life to them who live in Yunnan sudden unexplained death ward,and provide a scientific basis for taking effective measures to improve the people' s quality of life in the ward.Methods Using the cross-sectional household survey to collect the information of the inhabitants on social support and quality of life by the Social Support Scale,and the WHOQOL-brief Scale.Results The total score of social support,scores of subjective support,objective support in Yunnan sudden death ward ((40.85±8.34),(9.58±3.58),(23.86±4.87)) were lower than those of the control group in the same dimension ((41.82±7.12),(10.47±3.26),(24.51±4.68)) (all P＜0.05).But the score of social support utility in Yunnan sudden death ward (7.41±2.67)was no significant difference between the two groups (6.84±2.56,P＞0.05).After using multiple linear regression to control other confounding factors,such as house-hold income per capita,scores of social support,subjective support,objective support and social support utility were positively correlated with the score of quality of life in Yunnan sudden death ward (the correlation coefficient between the scores of social support and the dimensions related to the quality of life were 0.30,0.11,0.29,0.28,0.36;the correlation coefficient between the scores of objective support and the dimensions related to the quality of life were 0.15,0.05,0.13,0.14,0.19;the correlation coefficient between the scores of subjective social support and the dimensions related to the quality of life were 0.18,0.06,0.21,0.23; the correlation coefficient between the scores of social support utility and the dimensions related to the quality of life were 0.11,0.05,0.10,0.09,0.11 (all P＜0.05).Conclusions The people who live in Yunnan sudden death ward get less social support and social support utility is low,which cause the worse quality of their life.To make this situation better,more social support is necessary to enhance the utilization.
ABSTRACT
Objective To investigate the diabetes self-management (DSM) ability and influencing factors in patients with type 2 diabetes in Kunming. Methods A face to face questionnaire survey was conducted on type 2 diabetes patients admitted in the 1st Affiliated Hospital of Kunming Medical University from November 2010 to April 2012. Diabetes self-management instrument ( DSMI) was used to test self-management behavior, and psychological status was assessed by Problem Areas in Diabetes (PAID-5).Results 300 patients participated in the survey.The participant population consisted of 120 males (41.8%) and 168 females (58.2%) .A total of 190 patients (68%) suffered from DM related psychological problems.The mean DSM score was 95.23±20.6, and mean scores for the domain of integration DM care into one’s life, self-regulations, interaction with health professionals,self-blood monitoring glucose,and adherence to recommended regimen were 28.11±6.15,25.22± 5.67,23.06±6.41,10.98±2.96,and 8.75±2.21,respectively. There was no significant difference in the mean score between males and females (P>0.05) .Patients with psychological problems had lower scores in five DSM dimensions than those without psychological problems (P<0.05) . The result of multiple regression showed higher level blood glucose was negatively associated with DSM score, whereas patients with higher income was associated with a higher DSM score (P<0.05) .Conclusions The DSM situation is not good among patients with type 2 diabetes in Kunming, and most of the patients suffer from psychological problem. It is necessary to enhance the effective health education among diabetic patients.
ABSTRACT
Leptotrombidium eothenomydis.There was a wide niche overlap between any two chigger species with all indices beyond 0.76.Slight positive association existed between each two dominant species of chigger mites by the coefficient of association(V).Conclusion The community structure of chigger mites on the 7 major species of rodent hosts is complex,reflecting a high diversity of mite species.The niche breadth of the 6 dominant chigger species is different with a wide niche overlap.
ABSTRACT
Objective To understand the species,species distribution,the dominant species and their interspecies interaction of chigger mites on Eothenomys miletus(a dominant species of rats)in Yunnan.Method The rats were captured with mouse traps in 16 counties(or cities)during 2000-2004.All mites on the surface of two auricles of the hosts were collected and identified.The patch index(m*/m)and the coefficient of association(V)were adopted to judge the spatial distribution patterns and interspecies interaction of the dominant chigger mite species among different individuals of the rats(E.miletus).Results 1157 individuals of E.miletus were captured from 16 counties(citys).37613 chigger mites(belonging to 3 subfamily,9 genus and 80 species)were collected from the auricles(body surface)of 1157 rat hosts with a high “overall mite infestation rate”(68.2%)and “overall mite index”(32.5).Six species of mites were found dominant on E.miletus:Leptotrombidium scutellare,Leptotrombidium sinicum,Helenicula simena,Leptotrombidium eothenomydis,Herpetacarus hastoclavus and Leptotrombidium hiemalis.The distribution of the chigger mites among different individuals of E.miletus showed an aggregation pattern.Both positive and negative association existed between each two dominant species of chigger mites.Conclusion The species composition of chigger mites on Eothenomys miletus is complex with abundant individuals,which reflects a high species diversity of the mites.The main species of chigger mites tend to an aggregation on the body surface of E.miletus.
