Additional factors reviewed was basically perception out of a better lifetime (coded as the “1” should your new member believe its existence had improved inside before season and you may expected their lifestyle to switch in the further 12 months); the means to access machines (if or not professionals put a pc inside the prior one year within least regular); use of web sites (if users used the websites into the prior 12 months at the least once a week); the means to access public health characteristics; area (Northwest, Northeast, Main, Mexico City and you may State regarding Mexico, and you can South); and you can area of house (outlying or urban). I merely incorporated entry to societal health functions regarding the bivariate analysis because of the probability of reverse causality, as expecting mothers without entry to particularly services can afford to get enrolled in Seguro Common, a north american country wellness program that provides wellness attributes 100% free.

Statistical analyses

I calculated frequencies of ladies’ properties based on even when they’d ever already been pregnant. I and additionally said this new statistical dependence on differences between characteristics of individuals who got ever before already been expecting and people who got never ever come expecting having fun with chi-squared assessment. We held independent bivariate analyses for women aged fifteen-19 and also for feminine aged 20-24 exactly who didn’t get pregnant 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 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 adolescents that have an earlier sexual first (just before many years fifteen) stated actually having been pregnant (86%) compared to merely half those with an afterwards sexual debut

Dining table step one gift ideas new socioeconomic features of women exactly who stated ever before having sexual intercourse by being expecting and by ages-group (15-19 and you may 20-24). Local record was not rather on the ever being pregnant in the the latest teenage group. But not, one of adult female, ever being pregnant was significantly highest on native (87%) than in this new non-local category (64%). Certainly one of feminine planning college, 72% and you will 82% had never been expecting into the puberty and as young adults, correspondingly. On the other hand, merely twenty five% away from teenagers and twenty-two% off people had never been pregnant those types of exactly who prevent school. Tall differences of the educational attainment was indeed and seen. New proportion off actually ever-expectant mothers in age groups is actually rather higher for no. 1 or less minimizing secondary degree than for top supplementary and you will tertiary knowledge. Just about 9% away from adolescents and you can 24% from people that have tertiary training advertised actually ever being pregnant, versus 85% regarding adolescents and you will ninety% away from adult female having top or faster degree.

Relationship updates exhibited a powerful and you will tall organization which have previously which have become expecting. Extremely married otherwise cohabiting female said being expecting (85% certainly one of teenagers and 93% certainly one of young adults). Ages in the beginning sexual intercourse is tall simply for female below 20. That have elderly lovers (no less than a decade more mature) is rather of this higher pregnancy prices simply for the young mature female. I observed a critical association that have birth prevention parameters both for decades communities. More than 70% ones having fun with modern birth-control strategies advertised ever before having been pregnant. In comparison, below 40% of them whom advertised using a great condom for a change intercourse advertised ever having been expecting. Access to Suggestions and you may Communications Technical (ICT) was also rather associated with the previously having been pregnant in age groups. One particular having fun with machines and you will internet sites, the newest ratio of women reporting ever before having been expecting was straight down than just one of those exactly who don’t explore ICT. As well, bad feminine portrayed a high ratio away from ever before-expectant mothers (74% having adolescents and you may 81% to possess adults) than performed their low-poor counterparts (47% getting teenagers and you will 54% having adults). Ultimately, we seen a top proportion from actually ever-women that are pregnant certainly one of rural section for both age excellent site to observe range (70% to have adolescents and you will 78% getting grownups during the rural elements instead of 55% and you will 63%, respectively, for the towns).
