Other factors analyzed was impact from a better lives (coded since the “1” in the event your new member consider its life had enhanced for the preceding year and you can asked its life to change into the then 12 months); the means to access servers (if participants used a pc inside previous one year during the minimum once a week); use of sites (if participants made use of the web sites for the prior 1 year at the minimum weekly); accessibility societal fitness attributes; region (Northwest, Northeast, Central, Mexico City and you may State regarding Mexico, and you can Southern area); and you may part of quarters (rural otherwise metropolitan). We merely included usage of personal health attributes regarding the bivariate studies considering the probability of opposite causality, since the expecting mothers with no usage of instance properties can afford are signed up for Seguro Preferred, a mexican fitness system that gives health qualities free-of-charge.
Mathematical analyses
We calculated wavelengths from ladies services based on regardless if they’d actually ever been expecting. I together with said brand new mathematical requirement for differences between functions away from people that had ever before started expecting and people who had never already been pregnant using chi-squared tests. I conducted independent bivariate analyses for ladies aged 15-19 and for feminine aged 20-24 just who did not conceive just before many years 20.
We used general linear models (GLM) to assess associations with the outcome variables “ever pregnant” and “being a mother”. We hot chinese girl used GLM with log-link functions, Poisson distributions, and robust standard errors 18 18. Cummings P. Methods for estimating adjusted risk ratios. Stata J 2009; 9:175-96. , 19 19. Zou G. A modified poisson regression approach to prospective studies with binary data. Am J Epidemiol 2004; -6. considering that binomial models for prevalence ratios tend to underestimate standard errors and therefore generate narrower confidence intervals 19 19. Zou G. A modified poisson regression approach to prospective studies with binary data. Am J Epidemiol 2004; -6. . We estimated parsimonious stratified models by age (15-19 and 20-24 with no pregnancies before age 20) for all women who had ever had sexual intercourse prior to the survey. We included variables whose bivariate tests had a p-value < 0.25>
Most teens which have an early sexual introduction (just before ages 15) advertised actually ever having been pregnant (86%) weighed against merely half of those with a later sexual first
Table step 1 presents this new socioeconomic functions of women whom claimed ever having sexual intercourse by being expecting and also by decades-category (15-19 and you may 20-24). Native background was not somewhat of ever being expecting in the the newest adolescent class. However, among adult feminine, ever-being pregnant are notably higher on the native (87%) compared to the new low-local class (64%). Certainly women gonna college, 72% and 82% had not ever been pregnant in puberty and also as young people, correspondingly. On the other hand, just 25% out-of adolescents and you may twenty two% from adults had never been pregnant those types of which quit university. Extreme distinctions because of the instructional attainment was indeed as well as noticed. The brand new ratio of ever before-expectant mothers both in a long time is rather higher getting number 1 otherwise less minimizing secondary education than for upper second and you may tertiary education. Just about nine% off teenagers and you will 24% regarding people with tertiary knowledge advertised ever having been pregnant, versus 85% of adolescents and you may ninety% of mature feminine having number one or quicker studies.
Marital standing displayed an effective and significant organization that have actually with started pregnant. Very partnered or cohabiting women reported having been pregnant (85% certainly teenagers and 93% certainly one of teenagers). Ages initially sexual intercourse is significant simply for women around 20. That have more mature partners (no less than ten years elderly) was significantly from the large pregnancy prices only for the younger adult feminine. We observed a life threatening relationship that have birth-control parameters for both many years organizations. More 70% of these having fun with progressive contraceptive tips reported actually being expecting. By comparison, lower than 40% of them whom stated playing with a condom for a change intercourse advertised ever before having been expecting. Usage of Suggestions and you may Communication Technology (ICT) was also significantly for the ever before being pregnant in age groups. Some of those having fun with machines and you may sites, the new proportion of females reporting previously having been expecting try straight down than one particular just who failed to use ICT. While doing so, poor women represented a high proportion out-of actually-expecting mothers (74% to own adolescents and you will 81% for adults) than did their non-bad competitors (47% for teens and 54% for people). Eventually, i seen a higher ratio away from previously-women that are pregnant one of outlying parts for both a long time (70% to possess adolescents and you can 78% to own adults inside outlying section in the place of 55% and you may 63%, correspondingly, during the urban areas).
