Table 2 comes with multivariate regression coefficient quotes into the complete test, cisgender people, and you may cisgender female to have no-exorbitant Poisson regression models, plus both the logistic regression quotes to possess an upshot of zero (basic column) therefore the Poisson regression rates to your condom have fun with amount (second line). Self-confident (negative) coefficients toward logit mean a characteristic is on the a great high likelihood of reporting not using a condom (playing with a good condom), while confident (negative) Poisson coefficients try on the large (lower) matters out of condom play with. With the full attempt, brand new AIC = and you can BIC = . Diagnostic analytics (fitstat, Long and you can Freese 2014) indicate that the fresh new zero-inflated Poisson regression is more appropriate than simply Poisson, bad binomial otherwise no-inflated negative binomial for those investigation.
Demographics
In keeping with earlier education, we discover one several demographic factors influence models from condom use. Due to the fact markers regarding personal area, group factors figure social constraints, cultural and you will subcultural category subscription, and personal criterion in this sexual experience. Total, our efficiency indicate that many years, studies, matchmaking condition, expectation of getting an STI within the next 6 months, accessibility an alternate contraceptive, religious affiliation, and you can probably spiritual attributes are all constantly (also round the cisgender subsamples) and you will notably pertaining to your chances you to condoms was in fact never made use of during the last 10 experiences, whenever you are handling some other circumstances. Meanwhile, house income, relationships standing, and you may sex and you will intimate positioning are somewhat and you may constantly associated with what amount of moments condoms were utilized one particular just who utilized condoms. outlying residence. If you don’t, performance are very different because of the attempt or subsample.
Using forecast probabilities carrying every variables on its setting, i look at condom play with by the intersecting intercourse and you will sexual identity groups
Gender and you will intimate orientation influence patterns away from condom fool around with. The number one searching for with the sex and you can intimate orientation is the fact homosexual https://datingmentor.org/heated-affairs-review/, bisexual, otherwise pansexual cisgender boys explore condoms while in the penile-genital gender a whole lot more cisgender lady and you will heterosexual cisgender men carry out. Because this test is restricted so you’re able to participants’ profile of your last 10 genital-genital intimate knowledge, our abilities include a great amount of participants having a great lesbian, gay, otherwise bisexual title, who’re revealing only to their history ten penile-vaginal knowledge exclusive of any exact same-intercourse intimate relationships.
To possess dichotomous and you will continuous indicators, relevance is dependent upon t-examination of regression coefficients. That is denoted during the Dining table 2 with *, **, otherwise ***. Getting groups of dummy signs for categorical variables, benefit will be based upon a joint take to of one’s null theory that all coefficients for each class equivalent zero. For the Dining table 2, if possibilities the null hypothesis for this mutual benefits attempt was less than 0.05, the team out-of coefficients and you can practical mistakes try committed.
Inside Figs 6–nine, brand new predict odds is actually determined according to research by the seen research using Stata 16’s margins order to imagine predicted probabilities along side categories of great interest. In terms of these groups, gay/bisexual cisgender boys have the large predict number away from condom fool around with inside the penile-genital sexual intercourse, and you may upright cisgender ladies feel the lower (Fig 6). While it is perhaps not appropriate to help you generalize these results so you can gay guys, lesbian people, or bisexual someone while the a team, it is helpful to see one sexual title is a vital predictor out-of condom have fun with for even genital-vaginal intercourse simply.
We discover one ages was adversely on the condom have fun with. Young cohorts regarding people have fun with a lot more condoms than simply older cohorts, although controlling to other demographic characteristics. More mature age groups are all the more likely to report never using condoms, prior to younger groups. Predict odds reveal that for each and every rising generation is actually not as likely to make use of condoms (Fig 7). This looking holds to possess cisgender guys and cisgender females.
