That it varying was used so you’re able to estimate condom non-fool around with one of feamales in concurrent and you can serially monogamous relationships
A literature review identified sociodemographic variables, sexual history variables, and childhood characteristics associated with age at first intercourse and/or sexual partnering to be considered as potential confounders. We examined self-reported race [26-28] (white, non-Hispanic, black, non-Hispanic, Hispanic, or other, non-Hispanic), age at interview (21–24 years, 25–29 years, 30–34 years, 35–39 years, or 40–44 years), respondent’s education attainment (less than high school, high school graduate, or at least some college), current household income as a percentage of the federal poverty level (FPL) (<100% FPL, 100-199% FPL, ?200% FPL), and marital status (never married, currently married or cohabitating, or formerly ily factors, including socioeconomic status during childhood [29,30], are associated with earlier sexual intercourse [25,31] and more risky sexual practices including increased number of lifetime sex partners,[25,30] we considered these variables as potential confounders. Socioeconomic status during childhood was captured by self-reported highest level of parental education for both mother and father (less than high school, high school graduate, or at least some college). For paternal education only, “no father figure” was retained as a valid category. Absence of a father in the home has meaning as a proxy for childhood socioeconomic status .
Condom include in for the past 12 months certainly participants towards the NSFG try counted with the question,“ Considering straight back over the past 12 months, can you say you may have utilized an effective condom with your spouse to possess intercourse every time, more often than not, approximately half of time, a number of the day or not one of the time”.
Investigation
To help you take into account the newest advanced sampling design and you can weighting of NSFG, SUDAAN (ver. 11, Research Triangle Institute, NC, USA) was utilized. I described the fresh sociodemographic parameters along the five-level sexual partnering outcome varying: concurrent partnerships, serial monogamy which have a 1–3 month gap, serial monogamy with ?4 few days pit, and monogamous (referent). Chi-square was utilized to check on to have an improvement in size. In order to imagine the newest relationship ranging from time of intimate first and intimate partnering when you look at the adulthood if you’re on the other hand adjusting to have confounders, we conducted polytomous logistic regression. Basic, a harsh model was made. Following i sensed sociodemographic parameters and childhood circumstances as the potential confounders using an iterative approach to discover hence variables confounded brand new connection ranging from time out-of intimate debut and you may sexual integrating. While we noticed parameters one changed chances ratio having sexual integrating because of the over 10% due to the fact thing confounders, we integrated all potential confounders regarding finally activities when no loss of precision is actually know to attenuate the possibility to possess residual confounding. We derived chance rates (OR) and you may modified Otherwise (aOR) and you will 95% trust periods (CI) from the designs.
Performance
Concurrent partnerships in prior to interview was indeed said by 5.2% (letter = 478) of women. Serial monogamy try claimed because of the a maximum of 4% of women (letter = 363), dos.5% having openings ranging from lovers 1–ninety days and you may step 1.5% having gaps ?4 weeks. Of women reporting serial monogamy, 25.9% stated 30 days pit between lovers, 20.2% reported a few months, sixteen.9% claimed 90 days, 19.9% said 4–5 months in addition to 17.1% claimed ? 6 months between couples.
The mean age at first intercourse for women was 17.6 years (SE = 0.09). Women reporting concurrent partnerships in the last year had the youngest mean age at first intercourse (16.0 year; SE = 0.19) compared to serially monogamous women with 1–3 month gap (mean: 16.9 http://datingranking.net/local-hookup/spokane/ years; SE = 0.34), serially monogamous women with ?4 months gap (mean: 17.1 years; SE 0.25) and monogamous women (mean: 17.7 years; SE = 0.09). Figure 2 shows the percentage of women with younger, average, and older age at first intercourse by sexual partnering status; 25% of women in concurrent partnerships were <15 years of age at first sex, compared to 21% of serially monogamous women with 1–3 month gaps, 9.1% of serially monogamous women with ?4 month gaps and 11% of monogamous women. The median number of lifetime partners was 4 (Interquartile Range (IQR): 1–7). Concurrent women had the highest median number of lifetime partners (Median = 10; IQR = 6–20) followed by serially monogamous with 1–3 month gaps (Median = 7; IQR = 5–14), serially monogamous women with ?4 month gaps (Median = 7; IQR = 4–11) and finally monogamous women (Median: 3; IQR: 1–6). Nearly a quarter of women in each sexual partnering group (23% concurrent; 25% gap of 1–3 months between partners, 25% gap ? 4 months between partners) reported never using a condom in the prior year.
