RESUMO

The water environment capacity of urban parks is small, and their self-purification ability is poor. They are also more likely to be affected by microplastics (MPs), which cause an imbalance of the water micro-ecosystem. Based on the functional characteristics of parks (comprehensive park, community park, and ecological park), this study investigated the distribution characteristics of MPs in the water of Guilin parks through spot sampling, microscopic observation, and Fourier transform infrared spectroscopy. In addition, the pollution risk index and the pollution load index were used to evaluate the pollution risk of MPs.The results showed that the abundances of MPs in the park surface water and sediments ranged from 104.67-674.44 n·m-3 and 95.57-877.78 n·kg-1, respectively. There were four main shape types of MPs:fragments, fibers, films, and particles. MPs were dominated by fragments and fibers with small sizes (<1 mm). The polymers of MPs were polyethylene and polyethylene terephthalate. There were significant differences in the abundance of MPs in the water of different functional parks, and the abundance of MPs in comprehensive parks was the highest. The abundance of MPs in park water was closely related to the function of the park and the number of people entering the park. The pollution risk of MPs in the surface water of Guilin parks was low, whereas the pollution risk of MPs in sediments was relatively high. The results of this study indicated that tourism was an important source of MPs pollution in the water of Guilin City parks. The pollution risk of MPs in the water of Guilin City parks was mild. However, the pollution risk of MPs accumulated in small freshwater waters of urban parks requires continued attention.

RESUMO

OBJECTIVE: To estimate the association between three B-vitamin intakes and sociodemographic factors among adults in China. METHODS: We derived our data from the China Health and Nutrition Survey (CHNS) among 12,241 individuals aged 18-64 years. Log binomial regression was used to estimate adjusted prevalence ratios for factors associated with the inadequate intake of B-vitamins. RESULTS: Females with low incomes and living in the north had a higher prevalence of inadequate riboflavin intake than those with high incomes and living in the south. Both males and females living in a village had a higher prevalence of inadequate riboflavin intake than adults living in a city. Adults with low income, low education, and living in the north or in a village had a higher prevalence of inadequate niacin intake than adults with a high income, high education, and living in the south or in a city. CONCLUSION: We found that income, region, and area of residence were associated with riboflavin intake. Education, income, region, and area of residence were associated with niacin intake. Well-tailored strategies and policies are needed to improve nutritional status in China.

RESUMO

BACKGROUND: Understanding the factors influencing cognitive reactivity (CR) may help identify individuals at risk for first episode depression and relapse and facilitate routine access to preventative treatments. However, few studies have examined the relationship between CR and depression in Asian countries. This study was performed to assess the current status of CR among Chinese young adults and explore influencing factors. METHODS: A national cross-sectional online study using convenience sampling was conducted among 1597 healthy young adults in China (response rate: 93.94%) with a mean age of 24.34 (SD = 5.76) years. RESULTS: The mean CR score was 51.36 ± 18.97 (range 0-130). Binary logistic regression showed that a low level of CR was associated with the following factors: high self-compassion, high social support, high resilience, high monthly household income, and living in a rural area, with odds ratios (ORs) ranging from 0.14 to 0.70. Young adults in full-time employment, experiencing poor sleep, with high neuroticism, who reported frequent sad mood, and who had a high intensity of negative life events had increased CR to depression, with ORs ranging from 1.18 to 6.66. The prediction probability of these factors was 75.40%. Causal relationships among the influencing factors and CR could not be explored. CONCLUSIONS: The self-reported CR levels among Chinese young adults were moderate. Enhancing self-compassion, resilience, and social support for young adults and reducing negative life events, neuroticism, and poor sleep may help decrease CR. These findings may help healthcare providers or researchers determine how to cultivate and improve the CR of young adults by establishing documented policies and/or improving intervention efficacies.

RESUMO

BACKGROUND: Nursing interns are an important backup force for nursing professionals, so efforts to strengthen their patient safety (PS) competencies are a major priority. To do so requires assessing the strengths and weaknesses of Chinese nursing students' PS competence and identifying the influencing factors. METHODS: This was a multi-site, cross-sectional, web-based study that was carried out between September 2018 and January 2019. A national online survey was completed by 732 Chinese undergraduate nursing students. Our primary outcome factor was the Health Professional Education in Patient Safety Survey score. We also collected socio-demographic and clinical practice-related characteristics as independent variables. Multiple stepwise linear regression was performed to identify predictors of PS competence. RESULTS: Chinese undergraduate nursing students were fairly confident in their clinical safety skills but less confident in what they learned about sociocultural or context-dependent aspects of PS and speaking up about PS, including effective communication and understanding human and environmental factors. Less than half of the students felt that they could approach someone engaging in unsafe practice and were reluctant to voice concern about adverse events. We observed significant differences in PS competence between students from different regions, across different PS learning styles (self-study and classroom theoretical study), with different self-assessed PS competence levels, and with experiences of adverse events (p < 0.05). These factors accounted for almost 15% of the total variance in PS competence scores (adjusted R2 = 0.15, p = 0.00). CONCLUSIONS: The results of this study provide a better understanding of PS competence among final-year nursing students in China. Our findings may help nursing educators or healthcare organizations to cultivate and improve PS competence by establishing documented policies or by improving the efficacy of intervention.

RESUMO

The dietary zinc consumed in Chinese households has decreased over the past decade. However, the national dietary zinc intake in the last five years has seldom been investigated. Using data from 12,028 participants 18 to 64 years old (52.9% male) in the China Nutritional Transition Cohort Survey (CNTCS) 2015, we describe the intake of dietary zinc and the contributions of major foods and we examine the relationship between the level of dietary zinc intake and metabolic syndrome indicators, including blood pressure, fasting glucose, and triglycerides (TG), in Chinese adults. We assessed dietary zinc intake using 24 h recalls on three consecutive days. The mean daily dietary zinc intake for all participants was 10.2 milligrams per day (males 11.2 mg/day, females 9.4 mg/day, p < 0.001). The mean daily dietary zinc density for all participants was 5.2 mg/day per 1000 kilocalories. Among all participants, 31.0% were at risk of zinc deficiency, with dietary zinc intakes of less than the Estimated Average Requirement (EAR) (males 49.2%, females 14.8%, p < 0.050), and 49.9% had adequate dietary zinc intakes, equal to or greater than the recommended nutrient intake (RNI) (males 30.7%, females 67.0%, p < 0.050). We found substantial gender differences in dietary zinc intake and zinc deficiency, with nearly half of the men at risk of zinc deficiency. Males of younger age, with higher education and incomes, and who consumed higher levels of meat, had higher zinc intakes, higher zinc intake densities, and higher rates of meeting the EAR. Among all participants, grains, livestock meat, fresh vegetables, legumes, and seafood were the top five food sources of zinc, and their contributions to total dietary zinc intake were 39.5%, 17.3%, 8.9%, 6.4%, and 4.8%, respectively. The groups with relatively better dietary zinc intakes consumed lower proportions of grains and higher proportions of livestock meat. For males with adequate dietary zinc intake (≥RNI), TG levels increased by 0.219 millimoles per liter (mmol/L) compared with males with deficient dietary zinc intake (

RESUMO

OBJECTIVE: The aim of this study was to examine the status and characteristics of resilience among empty-nest elderly in a community in China using exploratory latent class analysis (LCA). METHODS: This study enrolled 250 empty-nest elderly as the study respondents. General information regarding the resilience of empty-nest elderly was investigated using the General Information Questionnaire and Connor-Davidson Resilience Scale, Chinese version, and we then used LCA and multivariate logistic regression to discuss the characteristics of resilience among empty-nest elderly individuals. RESULTS: Through the analysis, we found that the resilience of empty-nest elderly had obvious group characteristics and that statistical indicators can support the three categories of potential model. On the basis of the conditional probability on the various items of the questionnaire in each category, they were named "high resilience group," "low pressure resilience group," and "low resilience group," and the proportion was 26.6%, 40.4%, and 32.9%, respectively. Further study showed that age, marital status, education level, relationship with children, and physical exercise had a significant effect on the high resilience group compared to the low resilience group. Gender, education level, relationship with children, and physical exercise had a significant effect on the low pressure resilience group compared to the low resilience group. CONCLUSIONS: The resilience status of empty-nest elderly in communities can be divided into three categories. Each category had different characteristics of demographic information.

RESUMO

Only-child loss parents in China recently gained extensive attention as a newly defined social group. Resilience could be a probable solution out of the psychological dilemma. Using a sample of 185 only-child loss people, this study employed latent class analysis (a) to explore whether different classes of resilience could be identified, (b) to determine socio-demographic characteristics of each class, and (c) to compare the depression and the subjective well-being of each class. The results supported a three-class solution, defined as 'high tenacity-strength but moderate optimism class', 'moderate resilience but low self-efficacy class' and 'low tenacity but moderate adaption-dependence class'. Parents with low income and medical insurance of low reimbursement type and without endowment insurance occupied more proportions in the latter two classes. The latter two classes also had a significant higher depression scores and lower subjective well-being scores than high tenacity-strength but moderate optimism class. Future work should care those socio-economically vulnerable bereaved parents, and an elastic economic assistance policy was needed. To develop targeted resilience interventions, the emphasis of high tenacity-strength but moderate optimism class should be the optimism. Moderate resilience but low self-efficacy class should be self-efficacy, and low tenacity but moderate adaption-dependence class should be tenacity.

RESUMO

OBJECTIVE: To test the efficacy of a family-assisted smoking cessation intervention based on Motivational interviewing (MI) among low-motivated Chinese smokers. METHODS: A two-armed randomized controlled trial study design was utilized. 159 Smoker-supporter pairs were randomly allocated to the intervention (a family-assisted MI intervention-77) or control (an intensity-matched health education-82) group (IG & CG). Change in smoking characteristics, communication characteristics, Partner Intervention Questionnaire (PIQ), Decisional Balance Scale (DBL), and Situational Temptations Scale (STP) were measured at baseline, post-intervention, 3-month and 6-month follow-up. RESULTS: Compared to CG, IG had more significant increase over time in self-report quitting attempts of at least 24h, biochemically verified 7-day smoking abstinence, the Positive dimension of PIQ and the Cons in DBL, whereas the daily cigarettes smoked, the Pros in DBL and STP were showed more significant decrease over time in IG (P<0.05). After intervention, the communication frequency and satisfactory were also improved by smokers (P<0.01). CONCLUSION: The family-assisted MI intervention is more effective in changing the smoking behaviors and increasing the communication between smokers and family, than health education. PRACTICAL IMPLICATIONS: Using the family-assisted smoking cessation intervention based on MI, community health service providers can influence and empower low-motivated smokers positively for quit smoking.
