[Study on the risk factors of 100 cases with vulvar dystrophy].
OBJECTIVE
To assess the risk factors for vulvar dystrophy.


METHODS
An epidemiological study was carried out. Data on 100 cases with vulvar dystrophy was reviewed and face to face interviewed with a uniform questionnaire including the manner of work, environmental temperature, habit of eating, mood, underwear wearing, autoimmune diseases, marriage, menstrual age, the quantity of menses, orders of pregnancy, and labor trauma of vulvar during delivery, vulvitis and urethritis ect. Univariable analysis and multivariate logistic regression analysis were carried out with 1:1 case-control methodology.


RESULTS
Multiple conditional logistic regression analysis showed that vulvar dystrophy was positively associated with hot food (OR = 2.55, 95% CI: 1.24 - 5.25), mood (OR = 4.27, 95% CI: 1.96 - 9.29), order of pregnancy (OR = 3.37, 95% CI: 2.11 - 5.40), vulvitis (OR = 6.74, 95% CI: 2.66 - 17.09) and urethritis (OR = 11.02, 95% CI: 1.01 - 120.19). Vulviitis or urethritis increased 6.74 or 11.02 times the incidence of vulva dystrophy. Anger or nervous state contributed to the incidence of vulva dystrophy (OR = 4.27). Addict to hot food and order of labor also increased risk ratio for 2.55 and 3.37 times, respectively.


CONCLUSIONS
The risk factors of vulvar dystrophy were: addict to hot food, often holding a angry or nervous state, increase of labors, having vulvitis and urethritis.
