ObjectiveTo assess the level of health literacy and its influencing factors among middle school students aged 12‒18 years in Jing’an District, Shanghai, so as to provide a solid scientific foundation for further developing more targeted intervention measures. MethodsA stratified cluster random sampling method was used to randomly select 4 middle schools in Jing’an District, Shanghai from November to December 2023, and conducted a health literacy questionnaire survey on non-graduating middle and high school students, respectively. The2023 Survey on the Status of Health Literacy among Middle School Students in Jing’an District, Shanghai was adopted, which consisted of two parts: health literacy and basic information. Health literacy was divided into three dimensions: health knowledge and concept literacy, healthy lifestyle and behavior literacy, and health skill literacy. Three dimensions could be categorized into six types of health literacy issue: scientific health literacy, infectious disease prevention and control literacy, chronic disease prevention and control literacy, safety and first aid literacy, basic health literacy, and health information literacy. ResultsA total of 1 161 middle school students were enrolled into this study, including 571 males and 570 females. The overall health literacy level of middle school students was 33.51%, with 34.81% among middle school students and 31.69% among high school students, respectively. Results of logistic regression analysis showed that health knowledge acquisition and awareness, as well as application frequency of health knowledge, were the influencing factors for the overall health literacy level among middle school students (P<0.05). The degree of family attention to health maintenance, health knowledge acquisition and awareness, and application frequency of health knowledge were the main influencing factors for the three dimensions and literacy of six types of health issues among middle school students (P<0.05). ConclusionThe levels of different types of health literacy among middle school students in Jing’an District are uneven, with the highest being safety and first aid literacy and the lowest being basic health literacy. It is recommended to take targeted measures to comprehensively improve the health literacy level of middle school students.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective: To investigate the positive rate for 2019-nCoV tests and co-infections in Wuhan district. Methods: A total of 8 274 cases in Wuhan were enrolled in this cross-sectional study during January 20 to February 9, 2020, and were tested for 2019-nCoV using fluorescence quantitative PCR. Both respiratory tract samples (nasopharynx, oropharynx, sputum and alveolar lavage fluid) and non-respiratory tract samples (urine, feces, anal swabs, blood and conjunctival sac swabs) were collected. If both orf1ab and N genes are positive, they are classified as nucleic acid test positive group; if both orf1ab and N genes are negative, they are classified as negative group; if single gene target is positive, they are classified as suspicious group. Individuals were divided into male group and female group according to sex. At the same time, 316 patients were tested for 13 respiratory pathogens by multiplex PCR. Results: Among the 8 274 subjects, 2 745 (33.2%) were 2019-nCoV infected; 5 277 (63.8%) subjects showed negative results in the 2019-nCoV nucleic acid test; and 252 cases (3.05%) was not definitive (inconclusive result). The age of cases with COVID-19 patients and inconclusive cases was significantly higher than that of cases without 2019-nCoV infection (40 vs 56, t=27.569, P<0.001; 52 vs 56, t=6.774, P<0.001). The positive rate of 13 respiratory pathogens multiple tests was significantly lower in 104 subjects who were positive for 2019-nCoV compared with those in subjects who were negative for 2019-nCoV test (5.77% vs 18.39%, χ²=24.105, P=0.003). Four types of respiratory tract samples and five types of non-respiratory tract samples were found to be positive for 2019-nCoV nucleic acid test. Conclusion The 2019-nCoV nucleic acid positive rate in male is higher than in female. Co-infections should be pay close attention in COVID-19 patients. 2019-nCoV nucleic acid can be detected in non-respiratory tract samples.

Objective To clarify the status of tobacco exposure and identify risk factors of smoking among smear-positive pulmonary tuberculosis patients in Shenzhen,in order to provide a scientific basis for the formulation of tuberculosis-tobacco control strategy in Shenzhen.Methods From January to December 2016,a special survey was carried out in 8 districts in Shenzhen.A unified questionnaire was used to make face to face interviews for 958 smear-positive pulmonary tuberculosis patients registered in 2016.Descriptive statistics was conducted to analyze the status of tobacco exposure.Single factor analysis and multiple logistic regression were used to identify the important risk factors of smoking.Results Among smear-positive pulmonary tuberculosis patients in Shenzhen,the rates of general smoking,current smoking,regular smoking were 40.9％,34.2％ and 30％,respectively.All smoking rates were higher among male than female participants (x2=255.226,197.463 and 162.707,respectively,and the P values were all＜0.001);164cases of heavy smokers accounted for 50.0％ of current smokers.Among 392 smokers,64 had quitted smoking,and the rate of smoking cessation was 16.3％.Among 566 nonsmokers,the rate of passive smoking from cohabiting smokers was 17.8％ (101/566),and it was higher in female than male participants (23.1％ vs.12.3％,x2=11.219,P=0.001).In single factor analysis,gender,work or living environment,age,education level,marital status,and body mass index were closely related to smoking (x2=255.226,28.375,40.922,29.585,9.117,and 7.052,respectively,and the P values were all＜0.05).In multiple logistic regression,the major risk factors for smoking included in the model were gender (x2=120.797,P＜0.001),age (x2=5.728,P=0.017),education level (x2=17.159,P＜0.001),mode of case-finding (x2=3.670,P=0.055),work or living environment (x2=6.039,P=0.049),and marital status (x2=5.091,P=0.078).Conclusion The smoking status of smear-positive pulmonary tuberculosis patients was serious in Shenzhen.Tuberculosis patients were the key smokers.We should provide accurate intervention and health guidance for patients,such as,macro policy guidance,instillation of knowledge,mental health intervention,and smoke-free environment.

Objective: To determine the levels of vitamin D in patients with pulmonary tuberculosis in Shenzhen and identify the influencing factors of vitamin D levels and key groups of vitamin D deficiency, so as to provide a scientific basis for tuberculosis- and nutrition-related health education and promotion in Shenzhen. Methods: Patients with smear-positive pulmonary tuberculosis who were diagnosed in 2016 were selected as the research subjects. Their relevant information and blood samples were collected, and the sample pool was established according to the inclusion criteria. One hundred and twenty patients were selected based on simple random sampling, including 84 men (70.0%) and 36 women (30.0%). Blood 25-hydroxyvitamin D [25(OH)D] concentrations were measured using chemiluminescence technology. Vitamin D statuses in patients were statistically described, and vitamin D levels in patients with different characteristics were compared. Multivariate linear regression analysis was performed to identify important factors influencing vitamin D levels in patients. Results: Mean serum concentration of 25(OH)D in 120 patients was (40.2±16.0) nmol/L. There were 2 cases of vitamin D sufficiency (1.7%), 28 cases of vitamin D insufficiency (23.3%), and 90 cases of vitamin D deficiency (75.0%), of which 23 cases (19.2%) were of severe deficiency. 25(OH)D concentrations in patients with different lifestyles (indoors; indistinguishable indoors or outdoors; outdoors) were significantly different (35.3 nmol/L vs. 40.6 nmol/L vs. 49.5 nmol/L, F=8.274, P<0.001). Mean concentration of 25(OH)D in patients with sun exposure time of >30 min/d was higher compared to that in those with sun exposure time <30 min/d in the last month (46.4 nmol/L vs. 36.7 nmol/L, t=3.342, P=0.001). Multivariate linear regression analysis showed that the risk factors for 25(OH)D with statistical significance were Han ethnicity or not (β=-11.576, t=-1.991, P=0.049), housekeeping (including unemployment and retirement) or not (β=-6.136, t=-1.998, P=0.048), sun exposure time<30 min/d or none (β=-9.644, t=-2.829, P=0.006), body mass index (β=-2.056, t=-3.439, P=0.001) , and indoor degree of lifestyles (β=-4.419, t=-2.155, P=0.033). Conclusion Level of vitamin D is generally insufficient in patients with pulmonary tuberculosis in Shenzhen. It is necessary to strengthen health education related to vitamin D in patients with tuberculosis, especially in the high-risk population of vitamin D deficiency, such as in those with a lack of exposure to sunlight or high BMI.
