Other factors reviewed was in fact perception out-of a far greater lifetime (coded given that “1” should your new member consider their lifetime had increased inside the preceding 12 months and asked its life adjust from inside the then season); entry to hosts (if or not professionals utilized a computer when you look at the earlier 1 year within minimum once a week); entry to internet sites (if or not users utilized the internet sites inside earlier 1 year at the minimum weekly); use of personal fitness attributes; area (Northwest, Northeast, Central, Mexico Area and you can Condition from Mexico, and you can Southern); and area of residence (outlying otherwise urban). I simply provided access to public health characteristics from the bivariate research because of the odds of reverse causality, since women that are pregnant with no entry to such as attributes are able becoming subscribed to Seguro Common, a mexican wellness system that provides wellness characteristics free-of-charge.
Analytical analyses
I computed frequencies out-of ladies’ qualities centered on even though they had previously been pregnant. We in addition to stated brand new analytical dependence on differences when considering characteristics out-of people who got ever before come expecting and those who had never ever already been expecting playing with chi-squared screening. I held separate bivariate analyses for females old 15-19 as well as women old 20-24 whom didn’t become pregnant in advance of 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 teens which have a young sexual first (just before decades fifteen) claimed ever having been pregnant (86%) compared with merely half those with an after sexual debut
Table step 1 merchandise the newest socioeconomic properties of women whom claimed ever with sexual intercourse by being expecting by years-category (15-19 and you may 20-24). Local history was not notably from the ever being expecting inside the brand new adolescent group. Yet not, certainly one of mature feminine, ever-being pregnant is somewhat highest regarding the local (87%) than in the newest non-indigenous class (64%). Certainly women likely to university, 72% and you can 82% had never been expecting inside puberty so that as young adults, correspondingly. On the other hand, merely 25% away from adolescents and 22% regarding adults got never been pregnant one of those who stop college. High variations by the instructional attainment had been also seen. The fresh new proportion regarding ever before-expectant mothers both in age range are somewhat highest to possess top otherwise smaller minimizing additional degree than for top additional and you can tertiary training. No more than nine% out-of adolescents and you may 24% from grownups that have tertiary knowledge advertised ever having been expecting, versus 85% of teenagers and 90% out of adult female which have top otherwise smaller studies.
Relationship condition demonstrated a robust and you will high organization that have ever having become expecting. Very partnered or cohabiting women said being expecting (85% certainly teenagers and 93% certainly one of young people). Years in the beginning sexual intercourse are significant just for female less than 20. Which have earlier lovers (at the very least a decade more mature) are somewhat with the large maternity rates simply in the younger mature female. I noticed a serious association having birth prevention variables for age organizations. More than 70% of those having fun with modern birth control measures advertised ever being pregnant. By contrast, less than 40% of these just who advertised playing with an effective condom for once intercourse advertised actually ever having been pregnant. Entry to Pointers and Communication Tech (ICT) was also significantly for the ever being pregnant in both age range. Some of those using computers and you may sites, the new ratio of females revealing actually ever being expecting try lower than those types of whom didn’t fool around with ICT. In addition, worst female depicted a high proportion off previously-expectant mothers (74% to have adolescents and you may 81% for adults) than simply did their non-worst competitors (47% getting teens and you may 54% to own adults). Ultimately, i seen a high proportion away from previously-expectant mothers among outlying elements for a long time (70% for teens and you will 78% to possess grownups in outlying section versus 55% and you will 63%, respectively, in the cities).
