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 use in for the past season one of respondents for the NSFG was mentioned making use of the matter,“ Thought back for the past 1 year, is it possible you state you’ve got utilized a good condom along with your spouse for sexual activity each and every time, quite often, about 50 % of the time, a few of the big date or nothing of time”.


In order to account fully for this new state-of-the-art sampling design and weighting of your own NSFG, SUDAAN (observar. 11, Research Triangle Institute, NC, USA) was used. We discussed the new sociodemographic details along the five-peak intimate partnering benefit variable: concurrent partnerships, serial monogamy that have a 1–step three week pit, serial monogamy Vancouver local singles hookup app with ?4 month gap, and monogamous (referent). Chi-rectangular was applied to check on for a distinction in size. To help you guess the newest organization anywhere between timing from intimate first and you may sexual integrating in the adulthood when you are likewise adjusting to have confounders, we presented polytomous logistic regression. Basic, a crude design was made. After that we sensed sociodemographic parameters and you can youngsters situations given that possible confounders having fun with a keen iterative method to understand which parameters confounded brand new relationship anywhere between time out of intimate introduction and you can intimate integrating. While we felt variables one altered the chances ratio getting intimate partnering from the more 10% as the thing confounders, i integrated all-potential confounders in the last patterns whenever zero loss of precision try know to attenuate the likelihood getting recurring confounding. We derived potential rates (OR) and you can adjusted Or (aOR) and you can 95% trust times (CI) from the patterns.

Overall performance

Concurrent partnerships in the year just before interviews were claimed from the 5.2% (letter = 478) of females. Serial monogamy are reported from the a maximum of cuatro% of women (letter = 363), dos.5% that have gaps between partners 1–3 months and 1.5% that have gaps ?4 weeks. Of females revealing serial monogamy, 25.9% stated one month pit ranging from partners, 20.2% stated a few months, sixteen.9% stated 3 months, 19.9% said 4–5 days and 17.1% said ? 6 months between partners.

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 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.
