Objective: To explore the short-term effects of communicated activities regarding the China Healthy Lifestyle for All workshop held during September 2018. Method: "National action for three reductions and three health activities" and related content ( "salt reduction," "oil reduction," "sugar reduction," "oral health," "healthy bones," and "healthy weight" ) were used as keywords. Starting September 1, thematic publicity topics were launched and implemented throughout the month. The National Action Office issued promotional materials one day in advance through the WeChat Work Group known as the health promotion network in the mainland, which had been developed by members from different provinces, cities, and counties, to disseminate the materials for use both offline and online. Using search engines such as Baidu search and Sogou search, a third-party professional evaluation agency intelligently captured relevant information and texts from various organizations (including provinces, cities, and countries). The information was gathered and sorted according to different channels and forms; thereby, a database was formed for analysis. The content analysis method was used to quantitatively analyze the change trend of the release volume of related reports, and classified statistics were conducted according to different communication channels and forms. Baidu index, WeChat interactive volume, WeChat index, and Weibo hit times were used for evaluation. Researchers analyzed the difference of release volumes in different provinces (municipalities directly under the central government and autonomous regions), as well as in eastern and central regions. Results: The daily communication trend increased significantly after September, with 42 176 reports on related topics, peaking on September 3 (2 703 reports in a single day); effects of the topic establishment and publicity were shown during the entire month. The Badu index showed the same tendency. The keywords "three reductions," "three health," "all-people action," "oil reduction," "sugar reduction," "salt reduction," "oral health," "healthy bones," and "healthy weight" had become high-frequency words. From the perspective of communication channels, there were 17 576, 11 453, and 8 034 reports by WeChat, the news, and Weibo, respectively, accounting for 41.76%, 27.16%, and 19.05% of the total; these report rates were obviously higher than those of other communication channels. WeChat’s interactions reached 4 064 699, and the WeChat index rose to a peak of 858 275 on September 1, which was 194.44 times higher than on August 10 (before the promotional month); additionally, the number of micro-blogging hits reached 130 907 879. Regarding the form of presentation, in descending order, the most frequent type was graphics, followed by star propaganda, radio drama, and health super material. In addition, the gap between the top five provinces ranked by each channel was large. The number of daily releases varied significantly among provinces (municipalities and autonomous regions), with Beijing taking the top spot with 81 articles, while the western provinces of Xinjiang, Ningxia Hui Autonomous Region, Qinghai Province, and Tibet had relatively low daily releases. Even the gap of rank among the top five in WeChat, news, and individual micro-blogs were larger: Beijing, Shandong Province, and Zhejiang Province were the country’s top three regions in WeChat publishing volume. The communication effect in the eastern, central, and western regions was considerably different, with the eastern region clearly responding better than the other two regions, and the western region had insufficient propaganda capacity as a whole. Conclusion The communication effect of the China Healthy Lifestyle for All month activities in 2018 was quite effective, but the gap in communication effect by provinces was large.

Objective:To study the willingness of current smokers to quit smoking in rural areas and related factors to provide a reference for tobacco control.Methods:The data were collected from the China Chronic Disease and Risk Factor Surveillance in 2018. A multi-stage stratified cluster sampling was used to select 184 509 residents (≥18 years old); among the residents, 10 241 current smokers in rural areas were included in the study. χ2/ F test was used to analyze the factors such as willingness to quit smoking and demographic information, tobacco use, cognition of tobacco-related hazard knowledge, the prevalence of chronic diseases, and other factors. Unconditional multifactor logistic regression analysis was used in multivariate analysis. Results:A total of 3 453 (37.46%) considered quitting smoking in the next 12 months. Logistic regression analysis showed that occasional smokers were more willing to quit smoking than daily smokers ( OR=0.693 , 95% CI: 0.494-0.971), and those who smoked less than 1 pack per day were more willing to quit than those who smoked 1 pack or more per day ( OR=0.628 ,95% CI: 0.511-0.771), those who had quit smoking within 12 months were more willing to quit than those who had not quit within 12 months ( OR=0.438 , 95% CI: 0.357-0.537), and those with high awareness of tobacco hazards were more willing to quit smoking ( OR=1.056 , 95% CI: 1.028-1.086). The differences were statistically significant ( P<0.05). Conclusions:The willingness of current smokers in rural areas to quit smoking is related to the smoking situation, smoking intensity, previous smoking cession experience, and knowledge of the specific health effects of smoking. It suggests that health education should be strengthened through more efficient health communication methods in rural areas and provide brief smoking cessation interventions to improve rural smokers' willingness to quit smoking.

Objective:To analyze the burden of cardiovascular disease (CVD) attributed to low physical activity (LPA) and its changing trends in China from 1990 to 2019.Methods:On the basis of the province results of the Study of Global Burden of Disease 2019 in China, we described the distribution of CVD death and disability-adjusted life year (DALY) attributed to LPA by sex, age and province. Joinpoint 4.9.1.0 was used to calculate the average annual percentage change.Results:In 2019, the number of CVD deaths and DALY attributed to LPA in people aged ≥25 years were 0.127 million and 1.863 million person-years in China, respectively, The age-standardized mortality rate (ASMR) and standardized DALY rate of CVD attributed to LPA were slightly higher in men than in women, and much higher in ischemic heart disease patients than in ischemic stroke patients. The ASMR (8.85/100 000) and the standardized DALY rate (112.34/100 000) of CVD attributed to LPA in China in 2019 showed no obvious change compared with 1990, while decreased in the last decade. The largest increases in the mortality rate and DALY rate were observed in people aged ≥75 years from 1990 to 2019 (26.89%, 15.61%), but the mortality rate and DALY rate in people aged 60-74 years showed a decreasing trend. The mortality rate and DALY rate in men aged 25- 44 years showed the largest increases (37.50%, 35.49%), while women aged ≥75 years had the largest increases (31.00%, 18.02%). In 2019, the highest ASMR and standardized DALY rate of CVD attributed to LPA were found in Jilin, Inner Mongolia and Hebei. The largest increases were found in Qinghai (182.41%, 154.70%), Gansu (181.29%, 152.77%), and Chongqing (132.01%, 102.79%) and the largest decreases were found in Beijing (59.11%, 62.09%), Macau (41.89%, 39.37%) and Guangdong (36.93%, 40.72%) from 1990 to 2019.Conclusion:The disease burden of CVD attributed to LPA in China was quite high and showed gender, age and area specific differences.
