Methods The study was conducted from July to August 2024 and recruited participants via the Blued app.Univariate and multivariate logistic regression models were used to analyze factors associated with HPV testing and infection among MSM. Results Among the 1,080 participants,23.3% had undergone HPV testing,and 43.3% of those tested were positive for HPV. The main reason for HPV testing was the presence or suspicion of HPV-related symptoms(<i>n</i>=224,58.9%).Logistic regression analysis showed that MSM with higher levels of HPV knowledge,higher income,and those who self-identified as homosexuals were more likely to undergo HPV testing.Additionally,MSM with higher HPV knowledge,those who self-identified as homosexuals,those who had sex with women in the past six months,and HIV-positive MSM were identified as high-risk groups for HPV infection. Conclusions In China,the HPV testing rate among MSM using geosocial networking apps is low.However,the prevalence of HPV infection remains relatively high.Therefore,the government and community should enhance HPV knowledge dissemination,promote HPV testing,and improve the accessibility and quality of HPV testing services.By doing so,they can increase the testing coverage and effectively control the spread of HPV among MSM.</p>","PeriodicalId":6919,"journal":{"name":"中国医学科学院学报","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143960657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods Two hundred and ten college students(111 males and 99 females)aged 18-22 years old were recruited from Tianjin University of Science and Technology from April to June in 2023.Three-dimensional acceleration sensors were used to collect data of MVPA,LPA,SB,and sleep of college students.The body height,body weight,and waist circumference were measured,and four novel obesity indicators(ABSI,BRI,CI,and RFM)were calculated.The effects of substituting each activity behavior for 15 min on the obesity indicators were predicted,and the dose-effect relationship was explored at intervals of 5 min from -30 to 30 min.Results MVPA was negatively correlated with ABSI(<i>β</i>=-0.03,<i>P</i>=0.001),BRI(<i>β</i>=-0.27,<i>P</i>=0.049),CI(<i>β</i>=-0.10,<i>P</i>=0.001),and RFM(<i>β</i>=-9.95,<i>P</i>=0.004).LPA was negatively correlated with CI(<i>β</i>=-0.05,<i>P</i>=0.011)and RFM(<i>β</i>=-8.74,<i>P</i>=0.007).Neither SB nor sleep had correlations with ABSI,BRI,CI,and RFM.The results of 15 min isotemporal substitutions showed that increasing the MVPA time decreased the ABSI,BRI,CI,and RFM by 0.006-0.008,0.306-0.393,0.162-0.205,and 2.468-2.897,respectively.Decreasing the MVPA time increased the ABSI,BRI,CI,and RFM by 0.012-0.014,0.548-0.632,0.286-0.328,and 4.358-4.748,respectively.In the dose-effect relationship from -30 min to 30 min,MVPA was irreplaceable,and the negative benefits from substituting MVPA for other activity behaviors were much greater than the positive benefits from substituting MVPA for other activity behaviors.Conclusions Future research should take 24 hours activity behaviors as a whole.Increasing the time spent on MVPA and LPA and decreasing the time spent on SB is one of the effective ways to alleviate the obesity problem among college students.</p>","PeriodicalId":6919,"journal":{"name":"中国医学科学院学报","volume":"47 2","pages":"164-174"},"PeriodicalIF":0.0,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
