ABSTRACT

Background The current increasing trend of new cases of occupational noise-induced deafness indicates that the hearing loss of occupational population has not been effectively controlled in China. It is of great significance to study the characteristics of hearing loss among noise-exposed workers and its related factors. Objective To investigate characteristics and influencing factors of hearing loss among occupational noise-exposed workers in a large machinery maintenance enterprise, and to provide a scientific basis to prevent and control noise-induced hearing loss. Methods A cross-sectional survey was conducted to investigate male Han occupational noise-exposed workers in a large mechanical maintenance enterprise. We acquired demographic characteristics, occupational exposure history, and individual life behavior characteristics of the workers through questionnaires, collected occupational exposure level data from annual occupational disease hazard factor surveillance reports, obtained pure tone hearing threshold test data through occupational health examinations, and estimated individual noise exposure levels using cumulative noise exposure (CNE). According to the results of pure tone air conduction hearing threshold test, the workers were divided into a hearing loss group and a normal hearing group. The chi-square test was employed to compare the occupational exposure characteristics and individual life behavior characteristics between the two groups. Additionally, the trend chi-square test was utilized to analyze the changing trends of age, length of service, CNE, and hearing loss rate within the two groups. The relationship between high-frequency hearing loss in both ears and its related influencing factors was assessed by a multiple logistic regression model. Results The M (P25, P75) of CNE for the 2531 occupational noise-exposed workers was 97.51 (95.39, 99.96) dB(A)·year. The incidence of hearing anomaly, binaural high-frequency hearing anomaly, random ear high-frequency hearing anomaly, binaural low-frequency hearing anomaly, and random ear low-frequency hearing anomaly were 22.48%, 16.59%, 22.13%, 2.77%, and 3.52%, respectively. High-frequency hearing threshold increase was the main reason for hearing anomaly (98.42%). In comparison to the CNE ≤ 97 dB(A)·year group, the 97 dB(A)·year<CNE≤ 100 dB(A)·year group and the CNE>100 dB(A)·year group experienced a 36.4% and 52.3% increase in the risk of bilateral high-frequency hearing loss, respectively. The smoking group exhibited a 43.5% elevated risk of bilateral high-frequency hearing loss when compared to the non-smoking group. Conversely, the group frequently wearing hearing protection equipment demonstrated a 23.6% lower risk of bilateral high-frequency hearing loss in comparison to the group occasionally wearing protective equipment. The data suggested that CNE>97 dB(A)·year and smoking might be independent risk factors for bilateral high-frequency hearing loss, and frequently wearing hearing protection equipment might be an important protective factor. Conclusion Increased CNE and smoking can elevate the risk of high-frequency hearing loss, while personal hearing protection can effectively reduce the risk of hearing loss.

ABSTRACT

AIM:To investigate the changes of retinal microcirculation after phacoemulsification and the influencing factors of visual acuity.METHODS: Retrospective analysis. A total of 264 cataract patients(264 eyes)who underwent phacoemulsification in our hospital from January 2022 to December 2022 were selected as the study objects. Patients were divided into &#x0026;#x003C; 0.3 group(66 eyes)and ≥0.3 group(198 eyes)according to the recovery of best corrected visual acuity(BCVA)at 3 mo after surgery. The changes of retinal microcirculation indexes were compared before and after treatment. Logistic regression and LASSO regression models were used to screen the influencing factors of postoperative BCVA. A nomogram prediction model of postoperative BCVA was constructed and verified. A restricted cubic spline Logistic regression model was established to analyze the dose-response relationship between end-diastolic velocity(EDV), peak systolic velocity(PSV)and the risk of BCVA recovery.RESULTS: At 3 mo postoperatively, EDV and PSV were significantly improved compared with those before treatment, and resistance index(RI)levels were significantly lower than those before treatment(all P&#x0026;#x003C;0.05). Preoperative EDV, PSV, aqueous humor cell grade, fundus lesion grade, advanced age and Emery grade were influencing factors for poor BCVA recovery after phacoemulsification in cataract patients(P&#x0026;#x003C;0.05). The AUC before and after validation of the nomogram model by Bootstrap method were 0.869(95%CI: 0.815-0.903)and 0.866(95%CI: 0.802-0.895), respectively. The sensitivity was 88.36% and 88.27%, and the specificity was 91.82% and 91.78%, respectively. Restricted cubic spline model analysis showed no nonlinear dose-response relationship between EDV and PSV levels and the risk of poor BCVA recovery in either male or female(P&#x0026;#x003E;0.05).CONCLUSION: After phacoemulsification, retinal microcirculation in cataract patients improved significantly. EDV, PSV, aqueous humor cell grade, fundus lesion grade, advanced age and Emery grade are all factors influencing poor BCVA recovery after cataract surgery.

ABSTRACT

ObjectiveTo analyze the suicidal behavior in hospitalized patients with major depression and its influencing factors. MethodsA total of 1 000 patients with major depression admitted to our hospital from January 2017 to July 2021 were selected as the research subjects to investigate the status quo of suicidal behavior of the enrolled patients. According to the survey results, the patients were divided into suicidal behavior group and non-suicidal behavior group, and the related factors affecting their suicidal behavior. ResultsA total of 511 cases (51.10%) of the patients with major depression committed suicide in hospital, including 271 cases (27.10%) of suicidal ideation, 186 cases (18.60%) of attempted suicide, and 54 cases (5.40%) of suicide death. 489 patients (48.90%) did not commit suicide. Univariate analysis showed that there were significant differences in age, gender, marital status, loss of interest or pleasure, anxiety, sense of worthlessness or self-guilt, sleep status, personality, depressive episodes and paranoia between the suicidal behavior group and the non-suicidal behavior group (all P<0.05). Logistic multifactorial regression analysis showed that age ≤28 years (OR=1.54), female (OR=1.93), anxiety (OR=1.61), sense of worthlessness or self-guilt (OR=1.85) and paranoia (OR=2.15) were all independent predictors of suicidal behavior in the patients with major depression. ConclusionThe incidence of nosocomial suicide in patients with major depression is high. Early onset age, female, anxiety, sense of worthlessness or self-guilt, more depressive episodes and paranoia are independent risk predictors of suicide in patients with major depression. This finding can be used for clinical intervention to reduce the occurrence of suicide in patients.

ABSTRACT

ObjectiveTo investigate the detection rate and main influencing factors of growth retardation in infants aged 0-3 in Minhang District, and to provide relevant evidence for early intervention, nutrition promotion and health guidance in the future. MethodsFrom September 1, 2020 to August 31, 2021, the height, weight, basic information of parents, feeding methods, and lifestyle habits of infants who received systematic healthcare aged 0‒3 in community health service centers and Minhang maternal child health hospital were collected, and the current situation and influencing factors of infant growth retardation were analyzed. ResultsAmong the 68 637 infants who underwent a systematic physical examination in Minhang District, the total detection rate of growth retardation was 5.03% (3 453/68 637). The detection rates in the 0-year-old, 1-year-old, 2-year-old, and 3-year-old groups were 6.57% (1 636/24 885), 3.90% (664/17 031), 4.62% (827/17 905), and 3.72% (326/8 773), respectively. There was no difference in the detection rate of growth retardation between boys and girls (P>0.05), and a multinomial logistic regression analysis of 13 influencing factors (infant birth weight, birth length, parental weight, height, education level, mother’s childbearing age, delivery mode, household registration, feeding mode within 6 months, infant sleep, etc.) in univariate analysis showed that birth weight <2 500 g (OR=3.99, 95%CI: 2.809‒5.674) or ≥4 000 g (OR=12.78, 95%CI: 8.868‒18.443), maternal height <150 cm (OR=7.10, 95%CI: 4.294‒11.753), paternal height <160 cm (OR=5.65, 95%CI: 2.792‒11.422), maternal education level of junior high school and below (OR=1.31, 95%CI: 1.087‒1.588), paternal education level of junior high school and below (OR=1.02, 95%CI: 0.838‒1.236), mixed feeding (OR=1.15, 95%CI: 1.031‒1.288), and sleep duration exceeding the recommended time (OR=1.58, 95%CI: 1.466‒1.710) were risk factors for growth retardation in infants aged 0‒3. Infants with a birth length <50 cm or with household registration in Shanghai had a higher incidence of growth retardation. ConclusionGrowth retardation in infants aged 0‒3 is influenced by a combination of genetic, environmental, and sleep factors. It is essential for parents to realize the impact of growth retardation on the future of their children early on and actively participate in the early detection, screening, and intervention of growth retardation.

ABSTRACT

Background With the aging of China's population, cognitive impairment in the elderly is receiving increasing public attention. Screening and intervention of people with mild cognitive impairment (MCI) are of great significance to prevent and reduce the occurrence of cognitive impairment. Objective To understand the prevalence and explore potential influencing factors of MCI in the elderly in Songjiang District, Shanghai, and to provide scientific basis for promoting early screening of cognitive impairment and precise intervention of MCI in the elderly in this area. Methods A cross-sectional study design was adopted. From August to October 2022, using multi-stage random sampling, 1800 elderly residents aged 60 years and above were screened for cognitive impairment in 6 neighborhood/village committees in 6 towns in Songjiang District. The survey questionnaires included a sociodemographic questionnaire, a health status and lifestyle questionnaire, the Instrumental Activities of Daily Living (IADL), the Patient Health Questionnaire (PHQ-9), and the Mini-Mental State Examination (MMSE). Prevalence rates of MCI among the elderly by selected social demographic characteristics, health status, and lifestyle were estimated, and potential influencing factors of MCI were evaluated by binary logistic regression. Results A total of 209 elderly residents with MCI and 1591 healthy elderly residents were detected, and the prevalence of MCI in the elderly aged 60 and above was 11.6% in Songjiang District. Being physically active (OR=0.556, 95%CI: 0.399, 0.774) reduced the risk of MCI. Illiteracy (OR=1.810, 95%CI: 1.239, 2.644), primary school education level (OR=3.454, 95%CI: 2.342, 5.092), non-participation in social activities (OR=1.945, 95%CI: 1.360, 2.781), IADL damaged (OR=3.173, 95%CI: 2.137, 4.712), and depression (OR=1.957, 95%CI: 1.112, 3.443) increased the risk of MCI (P<0.05). Conclusion The prevalence of MCI among the elderly in Songjiang District is lower than the national average. Educational level, physical activity, participation in social activities, IADL, and depression may be the influencing factors of MCI in the elderly. It is recommended to carry out early screening, early detection, and early intervention for cognitive impairment in the elderly. Improving involvement in physical exercise and increasing participation in social activities are encouraged. Special attention should be paid to the needs of vulnerable groups such as low education level and disabled elderly during a community MCI intervention program.

ABSTRACT

ObjectiveTo explore the influencing factors of different scores on predicting death risk of extremely low birth weight infants (ELBWI). MethodsA total of 186 cases of ELBWI admitted by the Children's Hospital affiliated to Nanjing Medical University and the Lishui Branch of the Affiliated Zhongda Hospital of Southeast University were admitted from January 1, 2019 to January 1, 2021, and 125 ELBWIs were finally included after screening by inclusion and exclusion criteria. There were 47 cases in the death group and 78 cases in the survival group. General data and the items of score for neonatal acute physiology version Ⅱ (SNAP-Ⅱ), simplified version of the score for neonatal acute physiology perinatal extension (SNAPPE-Ⅱ), clinical risk index for babies (CRIB), clinical risk index for babies Ⅱ (CRIB-Ⅱ) and the national critical illness score (NCIS) were collected. Univariate and multivariate analysis was performed and nomogram was evaluated using receiver operating characteristic curve (ROC). ResultsIt was found that systolic blood pressure, maximum inhaled oxygen concentration, BE value and birth weight were important factors in ELBWI mortality risk assessment [systolic blood pressure OR: 0.968, 95%CI: 0.938-0.999, P=0.043; maximum inhaled oxygen concentration OR: 1.020, 95%CI: 1.006-1.034, P=0.006; BE OR: 0.868, 95%CI: 0.786-0.959, P=0.005; birth weight OR: 0.994, 95%CI: 0.991-0.997, P=0.000]. ROC showed that the area under the curve of the above four variables is 0.71, and the 95% confidence interval is 0.610-0.799, which is better than CRIB score. ConclusionLower systolic blood pressure, higher inhaled oxygen concentration, higher BE and lower birthweight are important influencing factors to predict the death risk of ELBWI. The above four items should be included in the newly developed score assessment to obtain a more effective ELBWI prediction system.

ABSTRACT

Globally, manufacturing workers are one of the most vulnerable groups to occupational injuries. Occupational injuries can lead to absenteeism, disability or even death, and most of the inflicted workers involve young adults aged 18-40 years, suggesting a safety and health problem that needs close attention. In the working environment of manufacturing industry, there are a variety of occupational injury risk factors, involving individuals, equipment, environment, and management, which should be considered comprehensively. This study found comprehensive research coverage on the influencing factors of occupational injuries in manufacturing industry at individual, environmental, and management levels at home and abroad, and rich research results on the impacts of psychological factors on occupational injuries. However, factors associated with occupational injuries in equipment safety and engineering like man-machine environment need further research. Influencing factors at all levels should be comprehensively considered in the surveillance and intervention of occupational injuries in manufacturing industry to protect health and safety of workers.

ABSTRACT

Background Work-related musculoskeletal disorders (WMSDs) seriously affect work efficiency and quality of life of nurses. Currently, there are significant differences in the published studies on WMSDs in nurses. Objective To systematically evaluate the prevalence of WMSDs among nurses in the mainland of China and analyze its main influencing factors. Methods Eight databases (CNKI, Wanfang data, VIP, SinoMed, PubMed, Cochrane Library, Web of Science, and Embase) were selected for searching literature reporting prevalence and influencing factors of WMSDs among clinical nurses in China from inception to December 31, 2022. The literature was included according to a pre-set criteria of inclusion and exclusion. The quality of cross-sectional studies was assessed using the criteria recommended by the Agency for Healthcare Research and Quality (AHRQ), and the extracted data were analyzed by Stata 15.0 software. A random effect model or a fixed effect model was selected to calculate combined effects based on heterogeneity of included studies. Results A total of 19 studies were included in this meta-analysis, including 14 studies published in Chinese and 5 in English, involving 17852 nurses in total. The estimated prevalence rate of WMSDs since work among clinical nurses in China was 85.5% (95%CI: 79.8%, 91.1%), the estimated annual prevalence rate was 81.0% (95%CI: 75.2%, 86.8%), and the estimated weekly prevalence rate was 65.0% (95%CI: 48.5%, 81.5%). The results of subgroup analysis showed that the prevalence rate of WMSDs among nurses in specific departments of emergency, ICU, and midwifery was 88.6% (95%CI: 82.6%, 94.6%), higher than that among nurses in general departments [79.0% (95%CI: 72.5%, 85.5%)]. The reported prevalence of WMSDs from 2018 to 2022 was 82.2% (95%CI: 75.0%, 89.4%), which was higher than that from 2004 to 2017 [76.8% (95%CI: 67.2%, 86.4%)]. Age >40 years (OR=2.34, 95%CI: 1.69, 3.24), length of service >10 years (OR=2.12, 95%CI: 1.43, 3.15), obesity (OR=2.73, 95%CI: 1.56, 4.77), night shift (OR=2.03, 95%CI: 1.81, 2.28), lifting heavy objects (OR=3.80, 95%CI: 1.79, 8.07), rest during work (OR=0.49, 95%CI: 0.30, 0.83), and bending (OR=3.47, 95%CI: 2.37, 5.08) were influencing factors of WMSDs in nurses. Conclusion The prevalence rate of WMSDs among Chinese nurses is high, and it is increasing year by year. Nurses in specific departments such as emergency, ICU, and midwifery show higher prevalence rates than those in general departments. Age > 40 years, length of service >10 years, obesity, night shifts, lifting heavy objects, and bending are risk factors for WMSDs among nurses, while rest during work is a protective factor. Therefore, early prevention actions should be taken targeting the above factors, such as increasing auxiliary assistance facilities and improving work patterns, so as to reduce the risk of WMSDs.

ABSTRACT

The 2030 Immunization Agenda of the World Health Organization (WHO) states that everyone in the world should fully benefit from vaccines to achieve good health and well-being. With the ever-changing disease spectrum and the improvement of residents' health literacy, relying solely on vaccines included in the National Immunization Program (NIP) is insufficient to meet the current requirements for disease prevention and control. Non-NIP vaccines play an important role in meeting people's diverse needs. Vaccine hesitancy is a global issue and an important factor affecting vaccine uptake. By reviewing relevant studies on vaccine hesitancy in recent years, this paper summarized different vaccination situations, current situation of vaccine hesitancy, measuring tools of vaccine hesitancy, and major influencing factors. It aims to provide references for the development of scientific and effective vaccine education strategies, which can increase public knowledge and understanding of vaccines, enhance healthcare professional's willingness and behavior in recommending vaccines, improve public vaccine literacy, and reduce vaccine hesitancy. At the same time, the supervision and guidance of media discourse should be strengthened to enhance the protective role of non-NIP vaccines in immunization barriers.

ABSTRACT

Aerosol microorganisms are important constituents of aerosols. They participate in physical and chemical reactions in the air and are also closely related to disease transmission and human health. With the SARS-CoV-2 pandemic, aerosol microorganisms have become a public health topic of great concern. Studying the composition and influencing factors of the air microbiome therefore has significant public health implications. Due to the limitations of traditional technologies for sampling and determination, the aerosol microbiome has not been fully understood. However, with the development and maturity of high-throughput sequencing technology, the aerosol microbiome has shown promising research prospects. This article reviews the composition, characteristics, detection methods and influencing factors of aerosol microorganisms, providing basic knowledge for further research on the air microbiome. In-depth research on microbial aerosols has significant implications on urban air quality control, national security and public health.

ABSTRACT

ObjectiveTo describe the characteristics of treatment outcomes of multidrug-resistant tuberculosis (MDR-TB) patients enrolled in second-line treatment in Shanghai from 2017 to 2018, and to analyze the influencing factors of treatment outcomes. MethodsTotally 182 MDR-TB patients were analyzed by using data collected from the China tuberculosis management information system, the hospital's electronic medical record information system, whole genome sequencing results and a questionnaire survey, and logistic regression analysis was used to analyze the factors affecting the success of treatment. ResultsIn 182 MDR-TB patients, the success rate of treatment was 65.4%, the loss to follow-up rate was 8.2%, the mortality rate was 4.9%, the unassessable rate was 13.7%, and the drug withdrawal rate was 7.7%. The factors affecting the success of treatment in MDR-TB patients included age (35‒ years old, OR=5.28, 95%CI: 1.58‒17.59, P=0.007; 55‒ years old, OR=16.30, 95%CI: 4.36‒60.92, P<0.001) and compliance to medication (OR=0.55, 95%CI: 0.42‒0.72, P<0.001). ConclusionThe treatment success rate of MDR-TB patients in Shanghai from 2017 to 2018 is significantly higher than the average level in China. Older patients and patients with less compliant are at higher risk of adverse treatment outcomes.

ABSTRACT

Objective@#To analyze the factors affecting the dropping-out from methadone maintenance treatment (MMT) in Hangzhou City, so as to provide the evidence for improving the compliance to MMT.@*Methods@#One MMT clinic was sampled from each of the eight districts in Hangzhou City using a cluster random sampling method, and patients that received MMT and were at ages of 18 years and older and registered during the period from December 2020 through June 2021 were recruited. Participants' basic characteristics, illegality and crime within 6 months prior to MMT and family and social relationships were collected through questionnaire surveys, and factors affecting the dropping-out from MMT were identified using a multivariable logistic regression model. @*Results@#A total of 315 outpatients were included from MMT clinics. The participants had a mean age of (45.33±7.63) years, and included 245 men (77.78%) and 70 women (22.22%), with a dropping-out rate of 65.71%. Multivariable logistic regression analysis showed a low likelihood of dropping-out from MMT among patients at ages of 60 years and older (OR=0.080, 95%CI: 0.018-0.350), employees (OR=0.415, 95%CI: 0.236-0.727), patients without drug-related infectious diseases (OR=0.411, 95%CI: 0.231-0.731), patients with per dossing of 60 mL and higher (OR=0.431, 95%CI: 0.236-0.787) and patients without contact with drug-using friends (OR=0.328, 95%CI: 0.185-0.582), and a high possibility of dropping-out from MMT among patients with poor relationship with family members (OR=2.905, 95%CI: 1.127-7.488). @*Conclusion@#Age, working status, drug-related infectious diseases, dosing, relationship with family members and contact with drug-using friends affected the dropping-out from MTT in Hangzhou City.

ABSTRACT

Objective@#To investigate the proportion of physical examinations among patients with severe mental disorders and its influencing factors in Shaoxing City, Zhejiang Province, so as to provide the evidence for improving the proportion of physical examinations among patients with severe mental disorders. @*Methods @#The epidemiological and clinical features of patients with severe mental disorders included in community management in Shaoxing City in 2022 were collected from Zhejiang Provincial Severe Mental Disorder Management Information System, including demographics, disease diagnosis and treatment, physical examination, and rescue and assistance. Factors affecting the physical examination were identified among patients with severe mental disorders using a multivariable logistic regression model. @*Results@#A total of 25 468 patients with severe mental disorders were enrolled in Shaoxing City in 2022, including 12 151 males and 13 317 females, with a male to female ratio of 0.91∶1, and the participants had a mean age of (54.34±14.71) years. Schizophrenia was the predominant type of severe mental disorders (15 419 cases, 60.54%), and 21 374 subjects participating in the physical examinations in 2022 (83.92%). Multivariable logistic regression analysis showed that female (OR=0.901, 95%CI: 0.832-0.975), urban areas (OR=0.506, 95%CI: 0.468-0.547), mental disorders due to epilepsy (OR=1.779, 95%CI: 1.104-2.866), hospitalized treatment (6 to 10 times, OR=0.523, 95%CI: 0.401-0.681; 11 times and more, OR=0.177, 95%CI: 0.108-0.288), special diseases in outpatient (OR=1.738, 95%CI: 1.597-1.891), receiving medical assistance (OR=2.851, 95%CI: 2.616-3.107), targets of the community care and assistance groups (OR=1.653, 95%CI: 1.471-1.857) and guardian (spouse, OR=1.777, 95%CI: 1.513-2.086; children, OR=1.277, 95%CI: 1.069-1.526; parents, OR=1.342, 95%CI: 1.143-1.576) were statistically associated with the proportion of physical examinations. @*Conclusions@#The proportion of health examinations was 83.92% among patients with severe mental disorders in Shaoxing City in 2022. Gender, residence, guardian, disease diagnosis, times of hospitalized treatment, medical assistance, special diseases in outpatients and target of community care and assistance groups were factors affecting health examinations among patients with severe mental disorders.

ABSTRACT

ObjectiveTo investigate the neurological outcome of children with dance-associated spinal cord injury without radiographic abnormality (SCIWORA) and explore its related factors and predictive model. MethodsFrom July, 2012 to January, 2022, 75 children with dance-associated SCIWORA hospitalized in Beijing Bo'ai Hospital were divided into improved group (n = 14) and non-improved group (n = 61) according to the American Spinal Injury Association Impairment Scale (AIS) grade a year later, and the related factors were analyzed. ResultsAll patients were girls aged four to ten years. Most of them were complete spinal cord injuries (52/75, 69%). The time of injury to rehabilitation (OR = 0.926, P = 0.046, 95%CI 0.858 to 0.999), the existing tendon reflex (OR = 46.915,P = 0.012, 95%CI 2.333 to 943.616) and muscle tension (OR = 8.932,P = 0.044,95%CI 1.063~75.067) were correlated with the AIS grade improvement. The combination of time of injury to rehabilitation, tendon reflex and muscle tone existing may predict the improvement of AIS (AUC = 0.953, P < 0.001,95%CI 0.878 to 0.989), the sensitivity and specificity were 100% and 83.61%, respectively. ConclusionThe neurological outcome of children with dance-associated SCIWORA is poor. Rehabilitation training as soon as possible is beneficial to the neurological recovery. Tendon reflexe and muscle tone existing at admission are closely related to improvement of neurological outcome, which could be used as potential indicators.

ABSTRACT

@#【Objective 】 To explore the influencing factors of Yang deficiency constitution in traditional Chinese medicine (TCM) from the perspective of mathematics with the use of calculation formulas, so as to protect patients from getting diseases caused by Yang deficiency constitution and provide suggestions for TCM disease prevention. 【Methods】  Based on the classification and determination criteria of TCM constitution implemented by China Association of Chinese Medicine, data for 24 solar terms from May 5, 2020(Start of Summer) to April 20, 2021 (Grain Rain) for the identification of Yang deficiency were collected by mobile constitution identification system. The grey correlation analysis method was used to determine the grey correlation degree of the factors influencing Yang deficiency constitution. In addition, a random forest model was constructed for the verification of the results from the grey correlation analysis, and for the evaluation of correlation degree between Yang deficiency constitution and its influencing factors. 【Results】  A total of 16 259 sets of data were collected from healthy or sub-healthy individuals aged from 18 to 60 years living in the central and northeastern parts of Sichuan Province(China) for the identification of TCM constitutions. After screening and preprocessing, a total of 544 sets of data for the identification of Yang deficiency constitution, involving 18 aspects of factors influencing Yang deficiency constitution. The results of the grey correlation analysis showed that there were 12 influencing factors whose grey correlation degree with Yang deficiency constitution was greater than 0.6. The accuracy of these 12 influencing factors with the training set and validation set of the Yang deficiency constitution random forest model were 98.39% and 93.12%, respectively. 【Conclusion】  In the sample data selected in this paper, grey correlation analysis is the appropriate technology to analyze the influencing factors of Yang deficiency constitution. It provides a new idea and a new methodological reference for the research and analysis of the influencing factors of TCM constitution.
