Other variables examined was impression out of a far greater lifetime (coded just like the “1” if your fellow member thought the life got enhanced during the before year and you will asked their lives to evolve within the then year); access to servers (if players made use of a pc in past 1 year on minimum once a week); entry to web sites (whether or not participants used the websites in prior 1 year during the the very least once a week); access to public fitness properties; part (Northwest, Northeast, Central, Mexico Urban area and you can County out of Mexico, and you will South); and you will area of house (outlying or metropolitan). We only included accessibility societal fitness qualities about bivariate studies due to the odds of contrary causality, just like the expecting mothers with no use of such as for example features are able to afford are signed up for Seguro Prominent, a mexican health program that gives health functions free of charge.
Statistical analyses
I calculated frequencies off ladies features according to even though they had actually ever been expecting. I in addition to advertised new statistical significance of differences when considering features out of people who got ever before become expecting and people who got never come expecting having fun with chi-squared evaluating. We held separate bivariate analyses for ladies aged fifteen-19 as well as for women old 20-24 who failed to get pregnant just before ages 20.
We used general linear models (GLM) to assess associations with the outcome variables “ever pregnant” and “being a mother”. We used GLM with log-link functions, Poisson distributions positive singles Hack, and robust standard errors 18 18. Cummings P. Methods for estimating adjusted risk ratios.

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 teenagers having an earlier sexual debut (just before years fifteen) said ever having been pregnant (86%) compared to merely half individuals with a later sexual debut
Desk 1 merchandise the fresh socioeconomic features of women who claimed ever before that have sexual intercourse when you are expecting and by ages-group (15-19 and you can 20-24). Indigenous background wasn’t notably regarding the ever being expecting into the the adolescent class. not, one of adult feminine, ever-being expecting is actually somewhat highest about local (87%) than in the non-native category (64%). One of feminine attending university, 72% and you will 82% had not ever been expecting within the puberty so that as teenagers, respectively. However, only 25% regarding teens and you can 22% of grownups got not ever been expecting among those who end college or university. Extreme variations from the academic attainment had been together with noticed. The latest proportion out of previously-expecting mothers both in age groups was notably large getting primary otherwise less minimizing secondary training than for top supplementary and you may tertiary training. Only about nine% from adolescents and you will 24% from grownups having tertiary education claimed previously being expecting, compared to 85% off teenagers and you will 90% from adult feminine that have primary or reduced training.
Marital position shown a strong and you will high connection which have actually that have become pregnant. Very married or cohabiting feminine stated being expecting (85% one of adolescents and you may 93% among teenagers). Ages in the beginning sexual intercourse is extreme only for women under 20. Having earlier people (at least ten years more mature) are notably associated with higher maternity rates merely when you look at the younger adult female. I observed a life threatening connection which have birth control parameters for ages organizations. More 70% of those using modern contraception methods reported previously having been pregnant. In comparison, less than forty% ones who stated using a condom for a change intercourse claimed actually ever being expecting. Access to Guidance and you can Telecommunications Technical (ICT) was also notably from the actually having been pregnant in a long time. One particular having fun with servers and web sites, the newest proportion of females reporting ever being pregnant are down than just one particular exactly who failed to fool around with ICT. Concurrently, poor women portrayed a higher proportion from ever before-expectant mothers (74% to own teenagers and 81% to own people) than just performed their non-terrible competitors (47% having teens and you may 54% having adults). Ultimately, we observed a higher ratio out-of previously-expecting mothers certainly outlying section both for age range (70% having adolescents and you will 78% getting people inside the outlying parts as opposed to 55% and you can 63%, respectively, within the towns).
