Investigation And Analysis Of Androgenetic Alopecia And Related Factors Among College Students In Jiamusi University

Objective To understand the prevalence of androgenetic alopecia among undergraduates of Jiamusi University and further explore the related factors affecting androgenetic alopecia,in order to provide clues for the etiology of androgenetic alopecia and provide reference for the general treatment and prevention of the patients.Methods The undergraduate students in Jiamusi University were selected as the research object,and the sample size was estimated by statistics.The sample size was divided into five layers by class and grade,and stratified cluster sampling was carried out.It is calculated that 29,28,27,25 and 3 classes should be selected from each layer for investigation.Isometric sampling method is adopted to rank the codes of classes of each grade.Random number is selected for the first class of each grade,and then sampled in sequence according to the sampling interval.There are 49 to 53 students in each class,and all the students in the selected class are investigated.A total of 112 classes and 5,675 people were planned to be selected,covering basic information,questionnaire evaluation scale and disease status.Questionnaires were distributed to the sample population through online links.The data were exported and sorted out through the platform,analyzed by SPSS software.Results 1.A total of 5951 questionnaires were collected,5747 of which were valid,and there were 418 AGA patients with a total prevalence rate of 7.27%,including 254 male patients with a prevalence rate of 11.10%and 164 female patients with a prevalence rate of4.74%.The prevalence rate of males was significantly higher than that of females.2.The BASP classification of AGA patients in Jiamusi University was mainly M₁V₁ in males and M₀F₁ in females.3.There are significant differences in gender,age,BMI,family history,smoking,hair care,skin type,some skin diseases,hair pulling test and diet between the two groups in the Chi-square test.4.There are differences between the AGA patients and controls in the scores of DLQI,average scores of SAS and SDS and scores of PSQI（P<0.05）.5.Spearman correlation analysis showed that gender,age,family history,hair pulling test,spicy,fried,overheated,coffee,strong tea,seafood,sweets,milk,frequency of hair dyeing and perming,frequency of shampoo,shampoo type,haircare products,temperature of hair dryer,smoking history,Acne,Seborrheic dermatitis,number of smoking,passive smoking and total scores of DLQI,SAS,SDS,PSQI scales were correlated with the prevalence,but not with disease BMI and yogurt（P>0.05）.6.Pearson correlation analysis showed that age,sex,frying,overheating,skin type,hair dryer temperature and shampoo type,DLQI scale total score,SAS scale total score and SDS scale total score were correlated with PSQI scale total score.There was no correlation between yogurt,sweets,coffee,hair washing frequency,perm frequency,hair pulling test and PSQI score of patients（P>0.05）.Conclusions 1.The prevalence rate of androgenetic alopecia among undergraduates in Jiamusi University was 7.27%,11.10%among males and 4.74%among females.M₁V₁was the most common in male AGA patients and M₀F₁ was the most common in female AGA patients.2.The scores of DLQI,the mean scores of SAS and SDS and PSQI of AGA patients were significantly higher than those of the controls.3.One-way Anova analysis showed that gender,age,family history,smoking and passive smoking,some diet,hair care,quality of life,anxiety,depression and sleep quality may influence AGA disease.
