[Health literacy and health status of Korean-Chinese elderly people living in Yanbian, China].

PURPOSE: This descriptive study was done to identify the relationship between health literacy and health status and to provide basic data for developing nursing interventions for Korean-Chinese elders living in Yanbian, China. METHODS: For data collection, intentional sampling of 300 elders was used. The questionnaire was composed of 5 items based on "Ministry of Health, the People's Republic of China (2008)" to measure health literacy, 33 health status items from the "Korean Health Status Measure for Elderly People" developed by Shin (2002), revised for use in China, and 9 general characteristics. Data were analyzed using SPSS Win 13.0 program. RESULTS: Total level of health literacy was relatively high (68.7%). Elders had high scores for taking medicines according to doctor's instruction, but lower ones for full comprehension through communication with doctors. Health status was high for emotional, physical, and social function in that order. There were significant differences between general characteristics and health status for gender, age, marital status, education, family, smoking, and alcohol consumption in that order. Results of multiple regression analysis for factors influencing health status showed that self-report health level was the most influential, followed by health literacy, age, gender. CONCLUSION: Health literacy is the main factor affecting health promotion among minority elders indicating a need to develop health promotion programs for elders who have low health literacy.

Monokine levels in cancer and infection.

The levels of monocyte intracellular monokines (TNFalpha, MIP, and MIG) in patients with cancer or bacterial infection were studied by multiparameter flow cytometry and comparative fluorescence analysis. TNFalpha, MIP, and MIG levels in peripheral blood of patients with cancer or bacterial infection were higher than in normal controls (p < 0.005). In normal controls, no significant relationships were found among TNFalpha, MIG, MIP levels, monocyte count, and lymphocyte count in peripheral blood. In cancer patients, TNFalpha was strongly related to MIP (r = 0.809, p < 0.001) and MIG (r = 0.773, p < 0.001). Of the 3 monokines, TNFalpha and MIG levels were related to monocyte count, but none showed correlation with lymphocyte count in cancer patients. In patients with bacterial infection, TNFalpha was not significantly related to MIP (r = 0.423, p = 0.051), but it was related to MIG (r = 0.457; p = 0.033). None of the monokines (TNFalpha, MIP, MIG) was related to the monocyte count, but the MIP level was related to the peripheral blood lymphocyte count in patients with bacterial infection (r = 0.559, p = 0.008). These results suggest that circulating monocytes may play an important role in both cancer and bacterial infection through increased production of monokines. Moreover, correlations of the monokine levels with each other and their relationships to the monocyte count differ in patients with cancer and bacterial infection.
