RP frequency was computed from the splitting what number of adolescents with RP plus the amount of teenagers whom knowledgeable a minumum of one pregnancy (plus the individuals currently pregnant) increased from the 100. RB frequency on the other hand try calculated by the splitting the fresh level of teens that have RB therefore the amount of teens which educated one livebirth multiplied by the 100. Deformalized survey weights had been used while calculating new incidence.
I made use of the ptrendi plan inside the Stata13 to perform Cochran–Armitage evaluating to choose the incidence development for every age bracket playing with the fresh new chi-square figure and you can conference the brand new presumptions away from an additive design. Cochran–Armitage take to are a modified Pearson’s chi-rectangular test and therefore analyzes new association between digital sexy ecuadorian women (i.e. RP and RB) and you may ordinal (we.age. seasons and years) classes. Multivariate logistic regression research with communications outcomes getting decades (we.e. age range playing with one another around three and you may five categories) and you can seasons try used while using the frequent pregnancy and you may delivery as the digital benefit details (we.elizabeth. sure if any). I counted the trend ranging from one or two straight questionnaire ages to spot hence attacks had extreme alterations in frequency. As well, i assessed style having fun with season and you may socio-geographic (i.elizabeth. part, form of quarters, and you can riches directory) communications for each age bracket. For the intended purpose of so it research, i used the three class generation since this is the newest simply categorization and that anticipate a sufficient number of cases.
Overall performance
Among feminine old fifteen–24 decades having one pregnancy (n = 7091), the vast majority (53.3%) was discovered among the 22–24 year olds. Despite the small ratio out of adolescents caught by surveys, the newest proportion out-of fifteen–18 seasons olds claimed regarding the questionnaire has grown over time out-of seven.64% (letter = 107) in the 1993 to help you % (n = 213) into the 2013 (discover Table step 1).
Development data for each age group
Prevalence fashion away from adolescents having repeated pregnancy regarding the Philippines out-of 1993 so you can 2013 by age group. Caption: So it contour gifts the newest adjusted incidence of repeated pregnancy using decades groups that have (a) about three and you will (b) five kinds. Teams making use of the about three kinds is fifteen–18 yrs . old, 19–21 years old and you can twenty-two–24 yrs . old since five groups plus 15–sixteen yrs old, 17–18 yrs . old, 19–20 years old, 21–twenty-two yrs old and you will 23–24 years old, because the represented from the for every line toward graphs. This new x-axis ‘s the survey 12 months setup during the chronological buy just like the y-axis the newest weighted frequency
Frequency style regarding teenagers having regular delivery on Philippines from 1993 to help you 2013 from the generation. Caption: That it shape gifts the adjusted frequency from frequent beginning playing with ages groups which have (a) three and (b) five kinds. Organizations making use of the around three kinds tend to be 15–18 years old, 19–twenty-one and you may twenty-two–24 years old as four kinds along with 15–16 years of age, 17–18 years of age, 19–twenty years old, 21–twenty two years of age and you can 23–24 years old, while the portrayed by per line on graphs. The fresh new x-axis is the survey year arranged when you look at the chronological purchase just like the y-axis brand new adjusted prevalence
Equivalent performance had been based in the regression studies. The fresh RP pattern one of 15–18 12 months olds stayed very nearly intact across the all of the studies out-of 1993 so you’re able to 2013 [Chances proportion (OR) =0.93; 95% Trust period (CI) =0.8step one–step one.07]. There clearly was an equivalent development away from RB trend in this decades class (Otherwise = 0.87; CI = 0.72–step one.06) following the an evident increase in frequency of 1993 so you’re able to 1998 (Or = step three.29; CI = 1.25–8.62). In addition, brand new earlier age groups presented a critical refuse for both RP and RB that have unadjusted ORs anywhere between 0.83 so you can 0.87 (come across Desk dos). Analyses having fun with four decades categories showed no factor on the manner in earlier times explained. Styles certainly one of 15–sixteen and 17–18 year old teens stayed intact, while a lowering trend was apparent for those old 19–20, 21–22 and you will 23–24.
