ABSTRACT
Objective To investigate health literacy and its influencing factors about the cancer prevention and control among urban residents in Guangxi. Methods Guangxi urban residents were selected by using multi-stage hierarchical cluster random sampling. Health Literacy resident cancer prevention and health literacy questionnaire, which was provided by National Urban Cancer Early Diagnosis and Treatment Project, were used for the face-to-face interview among participants. Results Among all the residents included in this study, 7.5 % had health literacy. Univariate analysis showed that gender, age, education, occupation, family income were influencing factors of health literacy(all P<0.05). The level of health literacy of female was higher than that of male. People aged 40-59 years old had the highest health literacy levels, while people aged 60 years old and above had the lowest health literacy levels. Business personnel and civil servant had higher health literacy levels than other professional staffs. The level of health literacy of residents with annual household income more than 8 ten thousand yuan was higher than that of other residents. Those with higher educational levels had better health literacy levels. Cancer prevention awareness and early detection, early diagnosis, early treatment awareness, two dimensions of cancer prevention and health literacy, was 57.2% and 17%, respectively. Logistic regression analysis indicated that gender, household income and occupation were independent factors influencing cancer prevention and health literacy in Guangxi urban residents. Conclusion The cancer prevention and health literacy levels of Guangxi urban residents are low and the development of cancer prevention awareness and early detection, early diagnosis, early treatment awareness is unbalanced. Gender, household income and profession are three independent factors influencing cancer prevention and health literacy.
ABSTRACT
Objective To investigate the prevalence and influencing factors of mild cognitive impairment (MCI) among elderly people in communities of Nanning, so as to provide scientific basis for the formulation of MCI early intervention measures. Methods A total of sample of 3 000 elderly people aged 60 or above living in Nanning area were sampled out using the method of cluster random sampling from three communities in Nanning. The Beijing version of the montreal cognitive assessment (MOCA-BJ) was administered by face to face interview. Results 833 MCI patients were detected. The standardized prevalence rate of MCI was 27.27% by the age composition of the population in Nanning in 2010. Single factor analysis showed that there were significant differences(all P<0.05)in the prevalence of MCI in different groups by age, education, occupation, exercise time, sleep time, number of reading, community activities and housework. Multivariate analysis showed that old age, primary education level, occupation of farmer/migrant worker and enterprise personnel/worker were the risk factors of MCI, adequate sleep time, moderate exercise time and reading times were the protective factors of MCI (all P<0.05). Conclusions The prevalence rate of MCI is high among the elderly in Nanning. The elderly with advanced age, primary school education, occupation as farmer/peasant-worker and enterprise personnel/workerare at high risk of developing MCI. Effective measures should be taken as soon as possible to prevent the occurrence and development of MCI.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between 5-HTTLPR and/or DRD4 gene polymorphisms and the accident tendentiousness of drivers.</p><p><b>METHODS</b>A case-control study, including 42 patients and 46 controls, were performed using type-A behavior questionnaire and EPQ scale. 5-HTTLPR and DRD4 gene -521 C/T were detected by the PCR-RFLP technique.</p><p><b>RESULTS</b>The scores of type-A behavior questionnaires, such as TH and TH + CH in exposure group were significantly higher than those in control group (P < 0.05). P and N scores of EPQ questionnaires in exposure group were significantly higher than those in control group, and L score in exposure group was significantly lower than that in control group (P < 0.05 or P < 0.01). There were significant differences in the frequencies of the genotypes and alleles of 5-HTTLPR gene between the cases and the controls (P < 0.05), but there were no significant differences in the frequencies of the genotypes and alleles of DRD4 gene between the two groups (P > 0.05). In the drivers with the accident tendentiousness, P scores in the cases with homozygous genotypes of the S/S in 5-HTTLPR gene were significantly higher than those in the cases with the genotypes of S/L and L/L in 5-HTTLPR gene (P > 0.05). E scores in subjects with homozygous genotypes of the T/T in DRD4 gene were significantly higher than those in subjects with genotypes of the T/C+C/C in DRD4 gene (P > 0.05).</p><p><b>CONCLUSION</b>The driver accident tendentiousness may be associated with 5-HTTLPR gene, but not associated with DRD4 gene. The two genes are associated with the type-A behavior and personality characteristics of drivers with accident tendentiousness. However, 5-HTTLPR and DRD4 gene may not have synergism in these behaviors and personality.</p>
