Additional factors analyzed was basically effect off a much better lives (coded once the “1” whether your fellow member envision the life had improved inside the preceding year and you will questioned the lives adjust into the after that seasons); the means to access machines (if or not users utilized a pc during the early in the day 12 months at the the very least regular); entry to sites (if or not players made use of the websites from inside the early in the day 12 months at the least regular); access to public wellness qualities; area (Northwest, Northeast, Central, Mexico City and County regarding Mexico, and you will Southern); and part of residence (rural or urban).

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.
