BackgroundThe influencing factors of primary dysmenorrhea in female college students were analyzed through meta-analysis to provide the corresponding basis for its prevention and treatment.MethodsThe databases, including China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP database, China Biology Medicine Disc, Pubmed, Embase, Cochrane library, and Web of science were searched for the literature on the influencing factors of primary dysmenorrhea in female college students was retrieved from the science database from the establishment of the database to July 17, 2023. The Newcastle-Ottawa Quality Scale was used to score the quality of cohort and case-control studies included in the study. The cross-sectional studies were scored by the Agency for Healthcare Research and Quality. Two researchers independently screened the literature, and if there was no consensus, the third party would make a judgment on whether to include the literature. The extracted content included the first author, publication year, country, study type, sample size, and influencing factors. Stata17.0 software was used for meta-analysis.ResultsA total of 23 studies were included, with a total sample size of 18,080 cases. Current evidence shows that the prevalence of primary dysmenorrhea in female college students is 70.3% (95%CI: 62.7-77.9%), and the combined odd ratio values (95%CI) of the main influencing factors are: family history of dysmenorrhea 2.116 (1.613-2.776), early age at menarche 2.200 (1.392-3.477), irregular menstrual cycle 1.662 (1.166-2.367), drinking cold drinks 1.717 (1.220-2.417), high caffeine intake 2.082 (1.379-3.144), stress 1.895 (1.515-2.282), medical specialty 1.827 (1.365-2.445), and adequate sleep 0.328 (0.232-0.463).ConclusionThe prevalence of primary dysmenorrhea is high in female college students, and adequate sleep is a protective factor for primary dysmenorrhea. Family history of dysmenorrhea, early age at menarche, irregular menstrual cycle, drinking cold drinks, high caffeine intake, stress, and medical specialty were all risk factors.Copyright © 2024 the Author(s).
