An Investigation On The Prevalence Of Androgenetic Alopecia And Its Related Factors In Students Of Ningxia Medical University

Objective: To understand the prevalence of androgenetic alopecia in Ningxia Medical University undergraduate and graduate students,analyze the factors that may affect androgenetic alopecia,and evaluate the effect of androgenetic alopecia on patients.Methods: Taking the undergraduates and graduate students of clinical specialties of Ningxia Medical University in grades 2017-2019 as the research objects,stratified sampling was conducted according to the ratio of undergraduates and graduate students.A total of 1527 students were collected,including 555 boys and 972 girls.Withdraw the basic information of the research subjects,the risk factors of androgenetic alopecia and the anxiety and depression evaluation form,and enter the collected data into the database,and use SPSS 22.0 software for statistical analysis to determine the risk factors of androgenetic alopecia.Result:1.Collected 1527 samples,109 patients with AGA,the total prevalence of androgenic alopecia is 7.1%;the prevalence of male androgenetic alopecia(≥ II)is 11.5%;the prevalence of female is 4.6%,male The prevalence is higher than that of women.2.Male androgenetic alopecia patients use the Norwood-Hamilton classification method with the largest number of grades II and III,and the BASP classification is mainly M1V1;female androgenic alopecia patients have the largest number of Ludwig classification is I,BASP classification.M0F1 mainly.The androgenic alopecia of Ningxia Medical University students is mainly mild to moderate.3.Univariate analysis AGA related factors: AGA and non-AGA have significantdifferences in gender,age,education,body mass index(BMI),skin type,marital status,smoking,sleep quality,family history and other factors(P <0.05).Age,high education,BMI≥23,oily skin,married,smoking,family members with AGA,sleep quality may be a risk factor for AGA.4.Logistic analysis of the risk factors of AGA further proves that: gender,age,marital status,family history are all risk factors for AGA,and sleep quality is a protective factor for AGA.5.The anxiety index of the AGA group was 46.81 ± 11.93,and the non-AGA group was43.84 ± 9.17.The anxiety index of the AGA group was significantly higher than that of the non-AGA group(P <0.05).6.The depression index of the AGA group was 52.08 ± 10.40,and the depression index of the non-AGA group was 52.28 ± 8.97.There was no statistical difference between the depression index of the AGA and non-AGA groups(P> 0.05).7.The detection rates of anxiety in AGA group and non-AGA group were 32.1% and23.3%,respectively,the difference was statistically significant(P <0.05).The detection rates of depression in AGA group and non-AGA group were 42.2% and 36.5%,respectively,and the difference was not statistically significant(P> 0.05).13.8% of patients in the AGA group had both anxiety and depression,and 10.6% in the non-AGA group had both anxiety and depression,the difference was statistically significant(P <0.05).Conclusion:1.The total prevalence of androgenic alopecia of students aged 18-30 in Ningxia Medical University is 7.1%;the prevalence of male androgenetic alopecia(≥ II grade)is11.5%;the prevalence of female is 4.6%,androgen Patients with sexual hair loss are mainly mild to moderate hair loss.2.The results of single factor analysis showed that gender,age,education level,body mass index(BMI),skin type,marital status,sleep quality,smoking,family history may berelated to androgenetic alopecia.3.Logistic analysis showed that gender,age,marital status,and family history are all risk factors for androgenetic alopecia;sleep quality is a protective factor.4.Patients in the androgenic alopecia group have anxiety.5.The detection rate of anxiety,coexistence of anxiety and depression in the androgen alopecia group is higher than that in the non-androgenic alopecia group.
