BackgroundThe human health damage caused by laryngeal cancer has attracted worldwide attention. But there is a lack of research on the incidence and mortality trend of laryngeal cancer among Chinese residents from 2005 to 2016.ObjectiveTo describe laryngeal cancer incidence and mortality trends in China from 2005 to 2016 by analyzing the incidence and death data of laryngeal cancer collected from Chinese Cancer Registry Annual Report, providing a reference for scientific prevention and control of laryngeal cancer in China.MethodsData about laryngeal cancer incidence and death in China during 2005—2016 were collected and input into Excel spreadsheets, then the annual standardized incidence, standardized mortality, age-specific incidence and age-specific mortality were calculated. Age-standardized rates were calculated by dividing the number of deaths caused by laryngeal cancer by the fifth national population census (2000) and multiplying by 1 000. Joinpoint Regression Program was adopted to calculate annual percentage change (APC) and average annual percentage change (AAPC) to analyze the temporal trends of annual laryngeal cancer incidence and mortality rates.ResultsFrom 2005 to 2016, the standardized incidence rate of laryngeal cancer in Chinese residents showed a decreasing trend (AAPC=-2.25%, P0.05) . The overall standardized mortality rate in urban areas was higher than that in rural areas. Males had a significantly higher standardized mortality rate than did females. The mortality rate increased gradually with age in those over 40 years old.ConclusionBy and large, the standardized incidence and mortality rates of laryngeal cancer in China showed a downward trend from 2005 to 2016, but showed sex- and age-specific and urban-rural differences. Therefore, targeted measures should be actively taken to develop prevention and treatment strategies to reduce the harm of laryngeal cancer.

This study investigated the relationship between perfectionism and relative deprivation among nursing students in China as well as the mediating role of interpersonal sensitivity and the moderating role of resilience in this relationship. A cross‐sectional study design involved 682 nursing students participants from two universities in Henan Province, China, using questionnaires about demographics, perfectionism, relative deprivation, interpersonal sensitivity, and resilience. Descriptive statistics, Pearson's correlation analysis and the PROCESS macro in regression analysis were used for data analysis. Adaptive perfectionism was not significantly correlated with relative deprivation, while maladaptive perfectionism was significantly positively correlated with interpersonal sensitivity, relative deprivation, and resilience. Interpersonal sensitivity mediated the relationship between maladaptive perfectionism and relative deprivation, accounting for 41.07% of the total effect. Moreover, the first half path and direct path of this process were moderated by resilience. These results show that targeted interventions to reduce maladaptive perfectionism, reduce interpersonal sensitivity and improve resilience of nursing students could help reduce their relative deprivation. Practitioner Points: The level of maladaptive perfectionism significantly positively predicted relative deprivation among nursing students.Interpersonal sensitivity is an important mechanism linking maladaptive perfectionism and relative deprivation. School administrators and teachers should diagnose and intervene in the interpersonal sensitivity of nursing students.The combination of reducing the level of maladaptive perfectionism and improving resilience is an effective method to reduce the relative deprivation of nursing students and promote their healthy development.

In recent years, the problem of mobile phone addiction (MPA) has become increasingly serious among mainland Chinese adolescents. Studies have found that self-esteem may be related to MPA, but the conclusions are inconsistent. Consequently, this meta-analysis aims to explore the real relationship between self-esteem and MPA, and analyze the moderator variables. The relevant studies used in meta-analysis were obtained by searching China National Knowledge Infrastructure (CNKI), Wan Fang Data, Chongqing VIP Information Co., Ltd. (VIP), PubMed, Web of Science, Scopus, Medline and Embase. Then articles were screened and coded, and statistical analysis was carried out by Stata 16.0 software. A total of 45,765 participants from 64 articles were included in the research. Meta-analysis showed that there was a moderate negative correlation between self-esteem and MPA(r = −.25, 95% CI = −.29, −.21). Subgroup analysis and meta-regression analysis showed that the age and publication time can significantly moderate the relationship between self-esteem and MPA, but MPA measurement instrument, gender, region and publication type have no significant moderating effect. The current meta-analysis provided solid evidence that self-esteem was negatively correlated with MPA. Longitudinal studies are needed to clarify the causality between them, so as to make more specific practice and policy recommendations. [ABSTRACT FROM AUTHOR]
