“…The observed prevalence of the singular use of conventional/electronic cigarettes among Chinese adolescents was 3.2/3.6%, which was comparable with the national figures reported in China in 2019 (4.7/3.6%) 5 and in England, Scotland, and Wales (4.9–11.0/2–3%) 25 , 26 , but was higher than the Japanese prevalence (0.6/0.7%) 27 . In the present study, the prevalence of SV was 4.7%, denoting a moderate but not total overlap as seen by the significant kappa statistics.…”

“…Despite mixed evidence, there are also worries that vaping would lead to conventional smoking 6 . The aforementioned report documented that 16.1% and 3.6% of Chinese middle school students had ever and currently vaped in 2021, versus 3.5% and 0.8% in 2019, respectively 5 . To inform effective interventions, research about factors of smoking conventional cigarettes or vaping (SV) and related mechanisms among Chinese adolescents is warranted.…”

INTRODUCTION Smoking conventional cigarettes or vaping (SV) poses significant health threats to adolescents. School climate and school identification are key elements of the school environment and potential factors of SV. Based on the Stress Coping Theory, the mediations between school climate/school identification and SV, via perceived stress/active coping, were examined. METHODS A cross-sectional survey was conducted among secondary school students from February to March 2022 in Taizhou, China. Structural equation modeling was used. RESULTS The prevalence of SV among the 7526 participants was 4.7% (singular use of conventional cigarettes: 3.2%; singular use of electronic cigarettes: 3.6%; dual use: 2.1%). School climate, school identification, and active coping were positively, and perceived stress (family stress, academic stress, and peer-related stress) were negatively associated with SV. The association between school climate and SV was fully mediated via: 1) school climate → perceived stress → SV; 2) school climate → active coping → SV; and 3) school climate → perceived stress → active coping → SV. The effect sizes were 52.1%, 43.8%, and 6.3%, respectively. Similar partial mediation mechanisms were found between school identification and SV, with relatively small effect sizes (<10%). CONCLUSIONS This study observed the prevalence of SV among Chinese secondary school students. School climate and school identification had both significant direct and indirect (via perceived stress/active coping) effects on SV. Positive school environments may reduce students’ stress and promote active coping. The stress coping mechanisms explained the association between school climate and SV better than between school identification and SV.

The Annual Report on Cardiovascular Health and Diseases in China (2022) intricate landscape of cardiovascular health in China. This is the first section of the report, which dissects influential factors across diverse domains. The investigation identifies tobacco use as a paramount concern, portraying China as the global epicenter of tobacco consumption. Cigarette smoking, exacerbated by second-hand smoke exposure, emerges as a critical and preventable risk factor, contributing to a surge in attributable deaths over the past three decades. In the realm of dietary nutrition, the study discerns an overall improvement, yet discerns worrisome deviations, notably an escalating fat intake surpassing recommended guidelines. The shifting dietary structure reveals diminished consumption of cereals and vegetables juxtaposed with an uptick in animal foods, while excessive intake of cooking oil and salt persists, straying substantially from endorsed levels. The exploration of physical activity patterns unfolds a nuanced narrative. Varied trends are observed among students, with concerns arising from sedentary behaviors and inadequate adherence to recommended guidelines. The analysis spans a trajectory of declining physical activity in Chinese adults, coupled with an alarming surge in sedentary leisure time, ultimately linking these factors to heightened risks of cardiovascular diseases and increased adiposity. An examination of overweight and obesity trends uncovers a relentless upward trajectory, projecting substantial prevalence by 2030. Noteworthy prevalence rates underscore the imperative for targeted interventions to curtail this burgeoning health crisis, with the anticipated prevalence extending to nearly two-thirds of the adult population. Psychological factors, notably depression, constitute an integral facet of cardiovascular health. Prevalence rates among patients with coronary artery disease and acute myocardial infarction underscore the intricate interplay between mental health and cardiovascular outcomes. Additionally, persistent depressive symptoms are shown to significantly elevate the risk of cardiovascular diseases and mortality. This first section underscores the multifaceted challenges facing cardiovascular health in China, emphasizing the imperative for tailored interventions across tobacco control, dietary habits, physical activity, obesity management, and psychological well-being to mitigate the escalating burden of cardiovascular diseases in the population.

“…[3] The 2021 Global Youth Tobacco Survey (GYTS) showed that the prevalence of experimentation with smoking among secondary school students in China was 16.7%, and the prevalence of smoking was 4.7%, with over a quarter of them being heavy smokers. [4] In 2018, the proportion of second-hand smoke exposure among non-current smokers aged ≥15 years in China was 68.1%. Today, the rate of e-cigarette use is 0.9%, the smoking cessation rate is 20.1%, and the relapse rate is 66.05%.…”

Recent decades have seen the remarkable development of China in medical accessibility and quality index, and the application of a number of new advanced cardiovascular technologies benefits more patients. However, according to the Annual Report on Cardiovascular Health and Diseases in China published in this article, which was organized and summarized by National Center for Cardiovascular Diseases, there is still a huge population living with risk factors of cardiovascular diseases (CVD), and the morbidity and mortality of CVD are increasing. It is estimated that there are around 330 million patients suffering from CVD currently, including 245 million of hypertension, 13 million of stroke, 45.3 million of peripheral artery disease, 11.39 million of coronary heart disease (CHD), 8.9 million of heart failure, 5 million of pulmonary heart disease, 4.87 million of atrial fibrillation, 2.5 million of rheumatic heart disease, and 2 million of congenital heart disease. Tobacco use, diet and nutrition factors, physical activity, overweight and obesity, and psychological factors are what affect cardiovascular health, while hypertension, dyslipidemia, diabetes, chronic kidney disease, metabolic syndrome, and air pollution are the risk factors for CVD. In this article, in addition to risk factors for CVD, we also report the epidemiological trends of CVD, including CHD, cerebrovascular disease, arrhythmias, valvular heart disease, congenital heart disease, cardiomyopathy, heart failure, pulmonary vascular disease and venous thromboembolism, and aortic and peripheral artery diseases, as well as the basic research and medical device development in CVD. In a word, China has entered a new stage of transforming from high-speed development focusing on scale growth to high-quality development emphasizing on strategic and key technological development to curb the trend of increasing incidence and mortality of CVD.
