Two models were conducted; the first solely incorporated the three sexual variables and the second included the background variables.
Frequency of intercourse prior to surgery was not associated with postoperative change in any of the sexual variables analyzed (P < 0.05).
In its final form, the survey included 16 questions evaluating demographic data and measuring the following sexual variables: libido (desire), frequency of intercourse, dyspareunia, orgasm frequency, multiple orgasm frequency and overall sexual satisfaction.
Before testing the mediation model between the three sexual self-schemas and the sexual variables, we computed zero-order correlations to test for the presence of a significant relationship between negative affect and the four target variables (Arousal-function, Satisfaction, VPA, and SSA).
From the comparison of models 1 to 4, it was shown that all injection variables had equivalent predictive power (AOR = 2.5) irrespective of time frame or the presence/absence of sharing practice, and that sexual variables had predictive powers that were equivalent to or more potent than the injection variables among the participants.
Salivary hormones (dehydroepiandrosterone sulfate-DHEAS, progesterone, cortisol, testosterone, estradiol and estriol) and socio-sexual variables were measured in 20 women taking oral contraceptives (OC group) and 20 not using OCs (control group).
With DHEAS as the exception, negative associations between hormones and socio-sexual variables were observed both at T1 and at T3, whereas positive associations were observed at mid-cycle.
Univariate associations between the sexual activity variables (outcome variables) and other variables were assessed using cross-tabulations.
Table 2 shows the effect of additionally adjusting the association of age at menarche with HSV-2 or HIV for socio-economic variables and sexual behaviour variables.
