Survey on health literacy and related factors among firefighters of emergency management departments in Southwest China.

OBJECTIVE: Although health literacy (HL) has emerged as a critical public health concern, research on HL in emergency management departments is limited. This study aimed to investigate the awareness of HL and associated factors among firefighters of emergency management departments in southwest China to provide a basis for carrying out targeted health education. METHODS: A cross-sectional convenience sample of 1,742 firefighters from an emergency management department in southwestern China was surveyed from February to April 2023 using the Chinese Citizen's Health Literacy Questionnaire (2019 version). The chi-square test, linear trend chi-square test, Fisher's test, rank sum test, and multifactorial logistic regression model were used to identify influential factors associated with HL. RESULTS: The HL level of the 1742 respondents was 34.3%. Age, ethnicity, education level, length of service, type of job, smoking status, types of parental jobs, annual household income, time of daily internet use, etc. (P < 0.05). The results of multivariate logistic regression analysis indicate that type of job (OR = 0.648, 95%CI:0.426-0.985), length of service (OR = 0.496, 95%CI:0.251-0.981), household income (OR = 1.900, 95%CI:1.443-2.502), daily internet usage time (OR = 0.726, 95%Cl:0.588-0.896), health status (OR = 0.750, 95%Cl:0.585-0.962) and frequency of organizing HL sessions (OR = 1.603, 95%Cl:1.101-2.330) were influencing factors affecting the HL of the officers and soldiers. CONCLUSION: The health literacy level of firefighters in the Emergency Management Department in Southwest China was 34.3%. Lower levels were found in the health-related skills dimension (HRS, 30.1%) and in infectious disease control (ID, 30.7%). Health information literacy (HI, 34.3%) was lower than the national level. The type of urban and rural areas, literacy level, and household income level may be the factors affecting the level of health literacy among the respondents. Therefore, health education and promotion interventions should target high priority dimensions (HRS, HI, and ID) and should focus on strengthening health literacy levels of firefighters with rural types, low education levels, and low household income to improve their health.

Combined multivariate statistical techniques, Water Pollution Index (WPI) and Daniel Trend Test methods to evaluate temporal and spatial variations and trends of water quality at Shanchong River in the Northwest Basin of Lake Fuxian, China.

Understanding spatial and temporal variations in river water quality and quantitatively evaluating the trend of changes are important in order to study and efficiently manage water resources. In this study, an analysis of Water Pollution Index (WPI), Daniel Trend Test, Cluster Analysis and Discriminant Analysis are applied as an integrated approach to quantitatively explore the spatial and temporal variations and the latent sources of water pollution in the Shanchong River basin, Northwest Basin of Lake Fuxian, China. We group all field surveys into 2 clusters (dry season and rainy season). Moreover, 14 sampling sites have been grouped into 3 clusters for the rainy season (highly polluted, moderately polluted and less polluted sites) and 2 clusters for the dry season (highly polluted and less polluted sites) based on their similarities and the level of pollution during the two seasons. The results show that the main trend of pollution was aggravated during the transition from the dry to the rainy season. The Water Pollution Index of Total Nitrogen is the highest of all pollution parameters, whereas the Chemical Oxygen Demand (Chromium) is the lowest. Our results also show that the main sources of pollution are farming activities alongside the Shanchong River, soil erosion and fish culture at Shanchong River reservoir area and domestic sewage from scattered rural residential area. Our results suggest that strategies to prevent water pollutionat the Shanchong River basin need to focus on non-point pollution control by employing appropriate fertilizer formulas in farming, and take the measures of soil and water conservation at Shanchong reservoir area, and purifying sewage from scattered villages.

Clinical evaluation and alternative site blood glucose testing of the EasyPlus mini R2N blood glucose monitoring system.

BACKGROUND: The complications of diabetes are preventable by exact glycemic control, which can be provided by an accurate self-monitoring blood glucose system to promote self-care in the management of diabetes. METHODS: We evaluated the accuracy and reliability of the EasyPlus mini R2N blood glucose self-monitoring system and compare glucose measurements between the fingertip, thenar, hypothenar and forearm. Over a 1-month period, 165 patients with Types 1 and 2 diabetes mellitus participated in this study. RESULTS: EasyPlus mini R2N blood glucose results obtained from the fingertip correlated well with the laboratory reference (linear regression analysis: slope=1.03, intercept=-1.63 mg/dl, r(2)=0.970) and were comparable to the results generated from 2 other blood glucose meters. Clarke error grid analysis showed all EasyPlus mini R2N glucose results in clinically acceptable zones A and B (96.79% in zone A and 3.21% in zone B). The CVs of the within-run and total precision testing were within the acceptance criteria (<6%). As compared to the alternate site, the fingertip correlated well with the thenar and hypothenar values and the forearm value. CONCLUSIONS: The EasyPlus mini R2N showed clinically acceptable accuracy and reliability as compared to the laboratory reference, and no significant or detectable glucose differences between alternate sites were observed.
