ABSTRACT
Objective:To describe the epidemiological characteristics of mental disorders in Ximeng Wa Au-tonomous County and explore psychosocial risk factors of mental disorders. Methods:Two thousand three hundred and eighty one residents aged 1 8 years and over were sampled using multistage sampling in Ximeng Wa Autono-mous County in 2013. All respondents were investigated by face-to-face interview. Mental disorders were screened out by using the General Health Questionnaire (GHQ)and diagnosed according to the International Classification of Diseases Checklist (ICD-10-Checklist)criteria. Results:Life time prevalence of any mental disorder was 19. 86%(419/2110). The lifetime prevalence rates of substance use disorder,anxiety disorder,insomnia,mood disorder, schizophrenia were 12. 99%(274/2110),6. 30%(133/2110),2. 94%(62/2110),2. 32%(49/2110)and 1. 00%(21/2110)respectively. Male (OR=0. 43),older age (35 -49 years,OR=1. 78;50 -64 years,OR=2. 59;≥65 years,OR=3. 5 1 ),unmarried and other marital status (OR=0. 3 1 ),non-Wa and non-Lahu ethnic groups (OR=0. 29)were associated with neurotic,stress-related and somatoform disorders. Male (OR=2. 41),older age (35 -49 years,OR=2. 29;50-64 years,OR=3. 20;≥65 years,OR=4. 58),non-farmer and non-self-employed occupation (OR=0. 41),and non-Wa and non-Lahu ethnic groups (OR=0. 32)were associated with psychoactive substance use disorder. Male (OR =0. 35 ) and order age (≥65 years,OR =3. 05 ) were associated with mood disorders. Conclusion:Lifetime prevalence of any mental disorder,substance use disorders and anxiety disorders are high in Ximeng Wa Autonomous County. Measures should be strengthened against prevalence of mental disorders in ethnic minority areas.
ABSTRACT
Objective To explore the factors of medical anthropology related to malaria control among Wa Ethnic minority in Ximeng County, Yunnan Province. Methods The study was conducted by the combination of anthropology and epidemiology, qualitative and quantitative, statistical analysis and description. Results Wa people considered malaria as one of three major diseases in the community. In Wa Ethnical language, the word of malaria, “Saihui” (Sai-illness and pain, Hui-being attacked quickly), does not mean of fever. About one third of Wa people had not thought fever as one of malaria symptoms. Most of Wa people only knew vivax malaria, but not falciparum malaria. Only 32.7% of people could connect malaria with mosquitoes, and a few of them could confirm mosquitoes as the only malaria vector. The proportions of sound knowledge of malaria causes, prevention and treatment seeking assessed were lower than 25.0%. As a result of multivariate logistic regression, 3 kinds of malaria knowledge were closely correlated each other, and the connection between causal knowledge and prevention (adjusted OR: 36.610, 95%CI: 10.242-130.866, P
ABSTRACT
Objectives To learn the bednet use and influential factors among Wa and Lahu ethnics,and further to explore feasible ways of promoting the use of bednets and insecticide-treated nets (ITNs). Methods Questionnaire surveys and statistical analysis with EpiInfo 2000 software package were carried out. Results Only did 2.8% [95% confidence intervals(95%CI):1.2%-5.4%] of Wa and 4.8 % (95%CI:2.8%-8.1%) of Lahu ethnic members use bednets frequently or sometimes. Bednets were not available for 67.7% (95% CI:62.0%-73.1%) of Wa and 59.7% (95% CI:53.1%- 66.1%) of Lahu ethnic peoples. Most people who had bednets did not often use them for anti-mosquitoes. Results of multivariate logistic regression confirmed significant correlation between bednet use and knowledge of malaria prevention. Conclusion The coverage and use rates are very low in the two ethnical minorities. Health education, communication and social marketing are the strategies for promoting the usage of bednet and ITNs.
