Desk 1 Sociodemographic, sexual and other features of women old 15-24 who reported that have got sexual intercourse

Other variables examined was basically impact away from a much better lifestyle (coded as the “1” in case the fellow member envision the lifetime got increased inside the before seasons and you can expected their lifestyle to change within the after that year); the means to access servers (if or not members utilized a computer when you look at the earlier 12 months at the minimum once a week); usage of web sites (if or not participants made use of the sites when you look at the earlier in the day 12 months during the minimum once a week); accessibility societal fitness functions; region (Northwest, Northeast, Central, Mexico Town and you may County from Mexico, and you may Southern); and you can part of residence (outlying or urban). I simply integrated accessibility societal wellness features in the bivariate investigation because of the likelihood of contrary causality, given that pregnant women no usage of eg functions can afford are enrolled in Seguro Popular, a north american country fitness program that offers health functions free of charge.

Mathematical analyses

We calculated wavelengths from ladies qualities centered on no matter if that they had ever been pregnant. We along with said the brand new mathematical requirement for differences when considering qualities out of those who got ever before already been expecting and people who got never been expecting using chi-squared evaluating. We used independent bivariate analyses for females old fifteen-19 and also for women old 20-24 whom don’t conceive ahead 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>

Really teenagers which have a young sexual introduction (before ages 15) claimed ever before being expecting (86%) weighed against only 1 / 2 of people with an afterwards sexual introduction

Table step one gifts the socioeconomic functions of women exactly who advertised actually ever that have sexual intercourse by being pregnant and also by ages-classification (15-19 and you may 20-24). Local background was not rather in the ever-being pregnant during the the newest teenage class. However, certainly one of mature women, ever being expecting is actually notably higher in the local (87%) than in the fresh low-native class (64%). Among feminine going to college or university, 72% and 82% had not ever been pregnant for the puberty and as teenagers, respectively. However, simply 25% away from teens and you can twenty-two% regarding adults got never been expecting one of those whom quit university. High variations by instructional attainment were plus noticed. The brand new proportion of actually-women that are pregnant in age range try rather large to have first otherwise shorter minimizing second knowledge compared to top supplementary and you may tertiary degree. Just about nine% regarding adolescents and you will 24% of grownups with tertiary degree said actually being pregnant, as compared to 85% from teens and ninety% out-of mature female that have no. 1 or shorter studies.

Marital updates displayed a powerful and you may high organization which have previously with started pregnant. Extremely partnered or cohabiting women advertised being expecting (85% certainly teenagers and you can 93% certainly one of teenagers). Ages in the beginning sexual intercourse try significant only for women around 20. With old partners (no less than 10 years elderly) try notably associated with the high maternity prices simply when you look at the more youthful mature female. I noticed a serious association with birth control parameters both for ages organizations. More than 70% of those using progressive birth-control steps reported ever being pregnant. By comparison, less than 40% of them whom said using an effective condom for once intercourse reported actually ever having been pregnant. Usage of Advice and you may Interaction Technology (ICT) was also somewhat of the actually being pregnant in both a long time. Among those using servers and internet sites, the proportion of women revealing previously being expecting was lower than just among those exactly who don’t have fun with ICT. While doing so, worst feminine depicted a higher proportion out of actually ever-expectant mothers (74% to have teens and 81% to possess adults) than simply performed the low-bad counterparts (47% to have adolescents and you can 54% having grownups). Fundamentally, we observed increased proportion of previously-pregnant women certainly outlying portion for both a long time (70% having teenagers and you may 78% getting people within the outlying areas rather than 55% and 63%, respectively, for the urban areas).
