Objective To evaluate the effect of sexual health education for female nursing students. Methods Totals of 112 female nursing students were randomly selected from grade 2012.Their sexual knowledge was evaluated, and then were divided into three groups-high, medium and low, according to their sexual knowledge.The score of sexual health education was compared among groups.Results After the health education, the total score of sexual knowledge was (75.01 ±6.84), and the score of self-care, sexual transmitted disease, gynecological disease were (26.20 ±3.57), (18.15 ±3.45) and (30.66 ±4.50), which were significantly higher than (62.73 ±8.20), (20.25 ±3.75), (16.13 ±6.27) and (26.19 ±4.97) before the education, and the differences were significant (t=12.48, 12.09, 3.15, 7.80, respectively;P<0.05). The improvement of low score group was more significant compared with the medium and high score group, and the improvement of high score group was lower than medium and low score group, and there was a significant difference (F=38.38,P<0.05).There was no significant difference among different sexual education methods (F=0.35,P >0.05).Conclusions Sexual health education is an important way to enhance the sexual knowledge of female nursing students and it is necessary to develop various sexual health education methods in colleges and universities.

Objective To investigate the status and influence factors on mental health among young stuberculosis patients, and explore the correlation between mental health and social support, so as to provide scientific basis for the development of interventions.Methods A total of 200 young tuberculosis patients, aged ≤40 year, were selected in Xuzhou Infectious Hospital from May 2015 to August 2016,and investigated by self-designed general information questionnaire, Symptom Checklist (SCL-90) and Social Support Rating Scale (SSRS). The correlations were analyzed between mental health and social support.Results Compared with 1986 and 2006 national norm, the sum score of SCL-90 was (147.34±46.39) for involved youth (t=5.298, 5.280;P<0.05). In multiple regression analysis, the main influence factors included educational level, annual income for score of SCL-90. The score of SCL-90 was negatively correlated with scores of social support, subjective support and degree of support utilization (r=-0.232, -0.221, -0.407;P<0.05).Conclusions The mental health status of young patients with tuberculosis is poor, and social support is closely related to mental health. Medical staff should timely carry out psychological intervention measures to improve the mental health and promote the rehabilitation.

Objective: To understand classroom environmental conditions and their association with spinal curvature abnormalities among students of primary and secondary schools in Guizhou Province, so as to provide a basis for formulating school health policies and scientific prevention and control measures for abnormal spinal curvature in students. Methods: Using a stratified random sampling method, 471 schools (2 811 classrooms) were selected annually across the province from 2022 to 2024 in order to monitor and evaluate classroom environment according to national standards. Spinal examinations were conducted for 196 606 (2022), 194 876 (2023), and 195 048 (2024) students, and χ 2 test was used to analyze the correlation of desk and chair compliance with student spinal curvature abnormalities. Results: The qualified rates of classroom blackboard illuminance uniformity ( 85.41 %) and the blackboard size (82.24%) were the highest in primary and secondary schools in Guizhou Province, while the average blackboard surface illumination qualified rate (20.10%) was the lowest. The average desk illumination (50.11%-58.63%), desk illumination uniformity (61.92%-72.27%) and qualified noise rate (50.04%-51.94%) increased significantly in 3 years; in addition, the compliance rate of desks and chairs decreased from 25.00% to 13.52%, and the differences were all statistically significant ( χ 2=42.48, 80.93, 46.09, 129.72, all P <0.05). Middle school classrooms outperformed primary schools in terms of per capita area, average blackboard illuminance, blackboard illuminance uniformity, average desktop illuminance, desktop illuminance uniformity, and noise compliance ( χ 2=311.55, 12.41, 20.64, 40.76, 10.25, 52.47), but had lower compliance for blackboard size and reflectance ( χ 2=537.29, 7.59) (all P <0.01). Urban schools had higher compliance than suburban schools for per capita area, average blackboard illuminance, average desktop illuminance, and desktop illuminance uniformity ( χ 2=73.71, 17.68, 29.30 , 36.03), but lower compliance for desk-chair suitability, blackboard size, and blackboard reflectance ( χ 2=4.72, 26.02, 5.43 ) (all P <0.05). The spinal curvature abnormality detection rate was 0.83%. A significant association was found between abnormality detection and desk-chair non compliance ( χ 2=223.85, P <0.01). Conclusions Classroom environment hygiene in Guizhou schools is suboptimal. Strengthening school environmental hygiene infrastructure and greater attention to its impact on student s health are essential.
