ObjectiveTo investigate the incidence and trends of thyroid cancer in Wujiang District, Suzhou City, Jiangsu Province, from 2008 to 2022, and to provide a scientific evidence for the prevention and control of thyroid cancer. MethodsData on thyroid cancer incidence from 2008 to 2022 were collected from the Wujiang District Cancer Registry System. The data were stratified by year of diagnosis and age group, and indicators such as crude incidence rate, standardized incidence rate (SIR), age-specific incidence rate, and the average annual percentage change (AAPC) were calculated. ResultsBetween 2008 and 2022, a total of 2 244 new cases of thyroid cancer reported in Wujiang District. The overall crude incidence rate was 18.07/100 000, and the SIR was 16.02/100 000, with AAPCs of 28.30% and 30.59%, respectively. Among males, 543 new cases were reported, with a crude incidence rate of 8.88/100 000, a SIR of 7.98/100 000, and AAPCs of 24.99% and 28.19%, respectively. Among females, 1 701 new cases were reported, with a crude incidence rate of 27.00/100 000, a SIR of 23.80/100 000, and AAPCs of 30.06% and 31.97%, respectively. Both crude and standardized incidence rates increased significantly for the overall population as well as for males and females (P<0.05). The number and rates of age-specific incidences increased with age up to 55 years, peaking between 50 and <55 years. ConclusionThe incidence rate of thyroid cancer in Wujiang District is rapidly increasing. It is necessary to strengthen the prevention and control of thyroid cancer, especially among females, to mitigate the rapid increase in the incidence rate of thyroid cancer.

Objective: To investigate the trend in incidence and change in age at onset of lung cancer in in Wujiang District, Suzhou City, Jiangsu Province from 2012 to 2021, so as to provide a basis for strengthening targeted prevention and control of lung cancer. Methods: Data of lung cancer incidence from 2012 to 2021 were collected through the Wujiang District Tumor Follow-up Registration Information System. The crude incidence, truncated incidence for 35 to 64 years, and cumulative incidence for 0 to 74 years were calculated. Chinese population-standardized incidence, Chinese population-standardized average age at onset, and Chinese population-standardized incidence proportion were calculated using the age structure of the standard population from the Fifth National Population Census in 2000. The trend in incidence of lung cancer from 2012 to 2021 was evaluated using average annual percent change (AAPC). The trend in the Chinese population-standardized average age at onset of lung cancer from 2012 to 2021 was evaluated using a linear regression model. Results: From 2012 to 2021, the crude incidence, the Chinese population-standardized incidence and truncated incidence for 35 to 64 years of lung cancer in Wujiang District were 84.57/100 000, 37.28/100 000 and 52.10/100 000, respectively, all showing upward trends (AAPC=2.489%, 2.034% and 4.654%, all P<0.05). The cumulative incidence for 0 to 74 years was 4.48%, showing no significant trend (P>0.05). The Chinese population-standardized incidence was higher in males than in females (48.16/105 vs. 26.81/105). The Chinese population-standardized incidence of lung cancer in females showed an upward trend (AAPC=8.174%, P<0.05), while the trend in males was not statistically significant (P>0.05). The crude incidence of lung cancer showed upward trends in the total population and females aged 0-<45 years (AAPC=18.287% and 25.343%, both P<0.05) and those aged 45-<55 age group (AAPC=8.003% and 17.629%, both P<0.05). The Chinese population-standardized average age at onset of lung cancer in total population and females decreased from 67.58 and 65.48 years in 2012 to 60.15 and 54.88 years in 2021, with an average annual reduction of 0.611 and 0.964 years, respectively (both P<0.05). The Chinese population-standardized incidence proportion showed upward trends for the total population and females under 65 years (AAPC=3.879% and 4.639%, both P<0.05). No statistically significant trends were observed in the Chinese population-standardized average age at onset or incidence proportion in males (both P>0.05). Conclusions From 2012 to 2021, the incidence of lung cancer in Wujiang District showed an increasing trend and a trend toward younger onset age. Young and middle-aged females had emerged as a key target population for lung cancer prevention and control.

Objective:To construct the concept and its conceptual framework of hospital health literacy(HHL) for exploring the HHL promotion mechanism in the country.Methods:Based on the proceduralised grounded theory, twelve middle or senior managers of hospitals were selected for in-depth interviews and three hospitals were selected for field research from July 2021 to February 2022. Open coding, axial coding, and selective coding were used in data analysis, establishing the concept of HHL and its conceptual framework in China.Results:The conceptual framework of HHL was composed of an internal driver mechanism(hospitals improve their health literacy promotion management system, staff-led health literacy promotion, health literacy promoting physical environment construction), and an external driver mechanism(cooperate with external organizations and institutions to conduct health literacy promotion). The concept of HHL in China was derived as follows: the combination of supportive environments and human resources that health care organizations have in place can improve access and understandability of health information and simplify healthcare services to help patients of different health literacy levels more easily obtain, process, and understand health information as well as to make the most of medical services.Conclusions:Hospital health literacy promotion mechanism in China is a synergy between internal and external driver mechanisms.

Objective:To describe the current situation of health promotion and education in medical and health institutions in China, propose targeted improvement strategies and provide inspiration for medical and health institutions to implement the relevant content of the Health China Action.Methods:We searched China National Knowledge Infrastructure (CNKI) , WanFang Data, VIP China Science and Technology Journal Database, PubMed, Embase, Cochrane Library and so on. The retrieval time limit was from January 1, 2000 to December 30, 2021. The search content was the research on the theme of "health promotion and education in medical and health institutions".Results:A total of 20 articles were included. In the research on health promotion and education of medical and health institutions, the studies involved in "organization management" and "health education" were the most ( n=20) . There were 7 studies (35%) related to "smoke-free hospitals", 4 studies (20%) related to "work effect evaluation", and the studies on "healthy environment" was the least (15%, 3/20) . Conclusions:The work experience of attaching importance to organization management and health education, vigorously promoting the construction of smoke-free hospitals and institutions' health environment, and strengthening the effectiveness evaluation of health promotion and education can provide reference for medical and health institutions to implement the relevant content of health promotion in the Health China Action (2019-2030) .

Objective:To translate the health literate healthcare organization 10 item questionnaire(HLHO-10) into Chinese and examine its reliability and validity.Methods:The Chinese version of HLHO-10 questionnaire(HLHO-10-C) was developed by following the Brislin translation model of translation, back translation, cultural adaptation and questionnaire epistemological survey.Five experts and 1 071 medical staff from 24 healthcare organizations in Zhejiang province were selected to conduct the validity and reliability test of the HLHO-10-C.Results:The content validity indices at the item level and total questionnaire level of HLHO-10-C were from 0.8 to 1.0 and 0.96 respectively, and the results of the exploratory factor analysis showed good structural validity.Conclusions:HLHO-10-C proves adequate reliability and validity to serve as a tool for healthcare organizations in evaluating and becoming HLHO. It can also help the implementation of the Healthy China Initiative(2019—2030), which is a performance assessment mechanism for health education and promotion of healthcare providers and health care organizations.
