The Influential Associating Factors for Primary Dysmenorrhea: A Propensity Score-matched Analysis

Abstract

Background: Dysmenorrhea is a common painful nuisance for reproductive women. This study was to investigate the influential and modifiable factors, regarding health behaviors, lifestyles and dietary habits, for primary dysmenorrhea in a Taiwanese population.Methods:This cross-sectional study retrieved data from 5,000 individuals in the Taiwan Biobank. After excluding men, menopausal and cigarette smoke women and missing values, the 1,325 individuals aged 30 to 56 were analyzed. We used propensity score-matching (PSM) at 1:3 ratio, and the final sample size was 824. The data were analyzed in SPSS 22.0 using Chi-square test, Fisher’s test, Student’s t-test and conditional logistic regression method.Results:After PSM, univariable analysis showed that the higher incidence rates of dysmenorrhea were in exposure to tobacco smoke (P=0.007), less likely to cook at home (P=0.01) and more tendency of tea consumption (P=0.036). On multivariable analysis, compared with non-dysmenorrhea group, the risk of exposure to tobacco smoke was 1.42 times with AOR (CI) = 1.42(1.00, 2.02), P=0.048 and of having the habit of home-cooking was 0.74 times with AOR (CI) = 0.74(0.56, 0.98), P=0.034.Conclusion:The findings implied that exposure to tobacco smoke and no habit of home-cooking habit were the potential risk factors for developing primary dysmenorrhea.
