Objective: Chinese college students' level of health literacy is low, so, we explored the effect of knowledge contests on health literacy (HL) among Chinese college students. Participants: Students from universities in Jiangsu, China. Methods: Two repeated cross-sectional studies were used to compare the effects of the college students' contests. Chi-square tests and variance analysis were used to compare the HL levels and scores, respectively; logistic regression was used for multivariate analysis. Results: The levels of HL after each contest were significantly higher than those in the baseline survey (p < 0.05). There were statistically significant score differences (p = 0.023 and p = 0.001) after the contests in the two studies. Multivariable analysis of HL contest showed that school, grade, profession, completion time, and contest history were statistically significant. Conclusions: HL among Chinese college students was low and it is helpful to regularly hold health knowledge contests to improve these levels, especially for most non-medical students.

Introduction: The C-reactive protein/albumin ratio is a reliable indicator of outcome risk in several diseases. This study aims to evaluate prognostic power of the C-reactive protein/albumin ratio for in-hospital mortality and the dose-response relationship between the two in the oldest-old patients with acute ischemic stroke. Methods: A longitudinal observational study was conducted on patients with acute ischemic stroke (aged ≥80 years) from two tertiary hospitals between January 1, 2014, and January 31, 2020. Based on the tertiles of the C-reactive protein/albumin ratio, the patients were divided into three groups. Restrictive cubic spline and robust locally weighted regression analysis were performed on continuous variables to examine the dose-response relationship between the C-reactive protein/albumin ratio and in-hospital mortality risk. All-cause mortality during hospitalization was the outcome for this study. Results: The study included 584 patients (mean age = 84.6 ± 3.1 years; 59.6% men). The C-reactive protein/albumin ratio was divided into three groups, namely, T1 of <0.73, T2 of 0.73–2.03, and T3: >2.03. After adjusting for demographic and clinical characteristics, a higher C-reactive protein/albumin ratio was independently associated with in-hospital mortality. The hazard ratio for this association was 2.01 (95% confidence interval: 1.12–3.60, p = 0.019). A dose-response relationship between the C-reactive protein/albumin ratio and in-hospital mortality risk was observed. Sensitivity analysis found no attenuation in the hazard ratio in uninfected individuals, whereas no difference in the hazard ratio was noted in individuals with infections. Conclusions: When predicting in-hospital mortality in the oldest-old patients with ischemic stroke, the C-reactive protein/albumin ratio might be a helpful and convenient metric.

Introduction: It is crucial to identify predictors of mortality in the early stage of acute ischemic stroke for the oldest old (aged ≥80 years) because of their poor overall survival outcomes. However, limited data are available as the oldest old have often been excluded from previous clinical studies. Hence, we aimed to assess the predictive effect of red blood cell distribution width on in-hospital mortality and the dose-response relationship between the red blood cell distribution width and in-hospital mortality in oldest old with acute ischemic stroke. Methods: A retrospective cohort study was performed in two tertiary hospitals. Patients aged ≥80 years admitted due to acute ischemic stroke from January 1, 2014, to January 31, 2020, were included in the study. We divided the eligible patients into 3 groups with tertiles of red blood cell distribution width. Restrictive cubic spline and robust locally weighted regression analysis were performed to test the dose-response relationship between red blood cell distribution width and the in-hospital mortality risk. All-cause in-hospital mortality was the main study outcome. Results: Overall, 606 patients were included in the final analysis. Red blood cell distribution width was categorized into 3 groups (T1: <13.7%, T2: 13.8–15.7%, and T3: >15.7%). The rationality of this categorization was then validated with restricted cubic spline and robust locally regression smoothing scatterplot, respectively. After adjusting for demographic and clinical features, a higher red blood cell distribution width was independently associated with in-hospital mortality and the hazard ratio (HR) was 3.31 (95% CI 2.47–4.45, p < 0.001). There was a positive dose-response relationship between red blood cell distribution width and mortality risk. Sensitivity analysis identified no conspicuous change in the HR. Conclusions: Red blood cell distribution width may be a valuable and simple measure for predicting in-hospital mortality in oldest old patients with acute ischemic stroke. [ABSTRACT FROM AUTHOR]

The purpose of this study was to estimate the prevalence of unintentional injuries and to identify factors mediating the risk of unintentional injuries among internal migrant children in southern China using self‐reported data collected between April 2016 and March 2017. Logistic regression models were used to identify significant risk factors for unintentional injuries among the internal migrant children. The prevalence of self‐reported unintentional injuries among internal migrant children in this study was 19.15%. Internal migrant children exhibiting antisocial (antisocial behaviour vs. no behaviour problems, OR = 2.162, 95% CI: 1.194–3.915, p =.011) and neurotic behaviours (neurotic behaviour vs. no behaviour problems, OR = 2.064, 95% CI: 1.098–3.880, p =.024) were more likely to report unintentional injuries. There was a positive correlation between the number of risk behaviours and the prevalence of unintentional injuries among non‐migrant and internal migrant children. Children's behavioural problems were closely related to unintentional injuries and may be useful as predictors of unintentional injuries in children. [ABSTRACT FROM AUTHOR]
