ABSTRACT
Objective:To clarify the elements of post competency of public health professionals and technical personnel, and construct a post competency index system of public health professionals and technical personnel.Methods:Referring to the Hay Group Competency Dictionary and literature review method, the post competency information elements of public health professional and technical personnel were constructed, and were revised through the expert consultation method. Unit-level stratified sampling was used, and 120 public health professionals were invited to evaluate the importance of the elements. SPSS 26.0 was used for data analysis, the continuous data were expressed in ( x ± s) mode, and Pearson was used to study the degree of correlation of each dimension. Finally, the post competency index system for public health positions was constructed by using the factor analysis method to extract the common factor as the first-level index. Results:The index system contained 7 first-level indicators (43 items), including public health practice skills, clinical practice skills, professional basic subject knowledge, personal professional accomplishment, public health authority and management ability, public health leadership, and public health methodology knowledge. Its weight coefficients (%) were 20.03, 17.48, 15.89, 15.68, 13.98, 12.82 and 4.11, respectively. The elements with the highest materiality scores were personal protection, responsibility and professionalism.Conclusion:Personal protection and other public health practical skills and personal professional qualities such as sense of responsibility and professionalism are the core elements of public health positions, and it is recommended to strengthen the training of public health professionals' public health practical skills in actual work, and pay attention to the cultivation of personal professional qualities, so as to establish a better team of public health talents.
ABSTRACT
Background Occupational stress has become one of the main factors affecting people's physical and mental health, and there are many sources of occupational stress in petrochemical enterprises. Objective To evaluate the current situation of occupational stress and its related factors among employees in a petrochemical enterprise, and to provide a scientific basis for reduing the risk of occupational stress among employees in petrochemical enterprises. Methods In June 2022, a cross-sectional questionnaire survey was conducted in a petrochemical enterprise in Hainan, including a general information questionnaire for basic information, the Effort-Reward Imbalance (ERI) for occupational stress, and the Pittsburgh Sleep Quality Index (PSQI) for sleep quality. Chi-square test was used to compare differences in positive occupational stress by demographic characteristics, occupational characteristics, behavior, and occupational disease hazards. Logistic regression was employed to evaluate factors associated with occupational stress. Results Of the 1129 questionnaire distributed, a total of 999 valid questionnaire were returned,with a valid recovery rate of 88.5%. The positive rate of occupational stress among employees in the petrochemical enterprise was 29.5%. There were statistically significant differences in the positive rate of occupational stress among the employees grouped by gender, age, marital status, body mass index (BMI), monthly income, length of service, smoking, weekly working hours, type of work, working mode, sleep quality, noise exposure, and high temperature exposure (P<0.05). In terms of positive occupational stress among subcategories: workers being male (vs. female), working ＞40 h per week (vs. ≤40 h per week), regular day shift (vs. shift work), smoking (vs. not smoking), with exposure to noise and heat (vs. without such exposure), and having poor sleep quality (vs. good sleep quality) reported higher positive occupational stress rates (P＜0.05). The results of pairwise comparison showed that the positive rate of occupational stress in divorced (50.0%) or married (32.0%) workers was higher than that in single (27.1%) workers, and higher in operation workers (30.6%) than in other types of work (20.5%) (P＜0.05). The trend chi-square results showed that the positive rate of occupational stress increased linearly with the increase of age, length of service, BMI, or monthly income (P＜0.05). The results of logistic regression analysis after adjustment showed that workers who worked ＞40 h a week had a higher risk of occupational stress than those who worked ≤40 h a week, and the OR (95%CI) was 1.909 (1.135, 3.211); the workers of other types of work had a lower risk of reporting occupational stress than operation workers, and the OR (95%CI) was 0.513 (0.272, 0.968); the workers with noise exposure had a higher risk of occupational stress than the workers without, and the OR (95%CI) was 2.457 (1.070, 5.642). Conclusion The positive rate of occupational stress among employees in this petrochemical enterprise is high. Among them, operators, working hours per week＞40 h, and noise exposure may increase the incidence of occupational stress. The enterprise should actively take measures to reduce the occurrence of occupational stress among employees.
ABSTRACT
Objective:The transcription factor IIH (TFIIH) helicases XPB and XPD are responsible for opening the DNA strand around the lesion site and endonuclease XPG cleaves the damaged DNA strand on the 3’ side during nucleotide excision repair (NER). Polymorphisms in these three genes that affect DNA repair capacity may contribute to susceptibility of lung cancer. In this study, our objective is to conduct a case-control study of 100 Chinese patients with lung cancer and 100 cancer-free age and sex matched controls to analyse associations between these SNPs and lung cancer susceptibility.Methods:In this hospital-based case-control study, we genotyped 7 SNPs of XPB, XPD and XPG using matrix assisted laser desorption ionisation-time of flight mass spectrometry method (MALDI-TOF) to explore the association with lung cancer risk. To estimate the relative risk of lung cancer associated with SNP genotype, odds ratios (OR) and 95.0% confidence intervals (95.0% CI) were obtained from unconditional multinomial logistic regression models without and with adjustment for potential confounders including age, gender, cigarette smoking and alcohol consumption.Results:The results showed that individuals carrying XPB rs4150434 GA or AA genotype (OR per GA genotype, 1.997; 95.0% CI: 1.031-3.871; P=0.039; OR per AA genotype, 2.435; 95.0% CI: 1.037-5.718; P=0.037), and this association was also find in nondrinkers (OR per GA genotype, 2.477; 95.0% CI: 1.128-5.440; P=0.022). Individuals carrying XPG rs2094258 AA genotype had an increased risk of lung cancer (OR per AA genotype, 3.020; 95.0% CI: 1.015-8.980; P=0.040) compared with individuals with the GG genotype, especially in nondrinkers (OR per AA genotype, 4.020; 95.0% CI: 1.211-13.339; P=0.017). In addition, we found that XPG rs17655 CG or GG genotype associated with decreased lung cancer risk in drinkers (OR per XPG rs17655 CG genotype, 0.238; 95.0% CI: 0.061~0.925; P=0.034; OR per XPG rs17655 GG genotype, 0.l39; 95.0% CI: 0.021-0.938; P=0.032). Haplotype analysis of all 7 SNPs was also conducted. We found that the haplotype of XPB (rs4150441, G>A; rs4150434, G>A) GA and the haplotype of XPG (rs2094258, G>A; rs4771436, T>G; rs17655, C>G) ATC had an increased association with lung cancer.Conclusions:These findings suggest an important role of XPB rs4150434 and XPG rs17655 polymorphisms for a biomarker for lung cancer risk among the Chinese population.
