I computed this new mean, important deviation and you may prevalence rates from RP and RB a year for each age group

RP frequency was computed by breaking up what amount of teens having RP therefore the level of teens just who knowledgeable one maternity (together with those individuals already pregnant) increased by the 100. RB incidence on top of that is computed by the isolating the brand new level of adolescents having RB plus the quantity of adolescents just who experienced one livebirth multiplied because of the 100. Deformalized questionnaire weights have been applied when you’re figuring the fresh frequency.

We made use of the ptrendi plan from inside the Stata13 to do Cochran–Armitage assessment to choose the prevalence development for each and every generation playing with the latest chi-rectangular figure and you will appointment the latest presumptions of an ingredient model. Cochran–Armitage decide to try are a changed Pearson’s chi-rectangular try hence assesses the fresh organization ranging from binary (we.elizabeth. RP and ABD’de Hintliler iГ§in en iyi arkadaЕџlД±k uygulamasД± you may RB) and you may ordinal (i.elizabeth. seasons and years) classes. Multivariate logistic regression analysis having communication effects getting decades (i.age. a long time having fun with both around three and you may four categories) and you may year try held when using constant pregnancy and you can delivery just like the binary consequences details (i.e. sure or no). We mentioned the newest development anywhere between a couple of consecutive questionnaire many years to understand and this attacks got high alterations in incidence. In addition, we analyzed manner having fun with 12 months and socio-geographical (we.elizabeth. area, sorts of residence, and you will wealth list) telecommunications for each age group. For the true purpose of so it investigation, i made use of the about three classification age bracket that try new just categorization and therefore invited a sufficient number of cases.


Certainly feminine aged fifteen–24 age with one maternity (letter = 7091), the vast majority (53.3%) was indeed located one of several 22–24 12 months olds. Regardless of the quick ratio from adolescents captured from the surveys, brand new ratio out-of 15–18 year olds claimed in the survey has increased over the years away from eight.64% (n = 107) in the 1993 so you can % (letter = 213) from inside the 2013 (see Desk 1).

Trend studies for every age group

Frequency style regarding teens that have repeated pregnancy throughout the Philippines away from 1993 to help you 2013 by the age group. Caption: This figure gift suggestions new adjusted frequency off repeated pregnancy playing with years organizations with (a) about three and you will (b) four classes. Teams utilising the about three kinds were fifteen–18 yrs . old, 19–21 years old and you can 22–24 years of age as the five groups also fifteen–sixteen yrs . old, 17–18 years of age, 19–two decades old, 21–twenty two years of age and you can 23–24 years of age, since the portrayed because of the per line on graphs. The fresh new x-axis ‘s the questionnaire season set-up when you look at the chronological buy because y-axis the new weighted frequency

Frequency trends from teens with repeated birth regarding the Philippines out-of 1993 so you can 2013 by the age bracket. Caption: Which profile gift ideas the brand new weighted prevalence from regular delivery using ages communities with (a) about three and you may (b) five categories.

The fresh new x-axis is the questionnaire seasons created when you look at the chronological order since the y-axis new adjusted prevalence

Similar overall performance was in fact found in the regression studies. The fresh RP trend among fifteen–18 season olds remained virtually intact round the all of the surveys regarding 1993 so you’re able to 2013 [Chance proportion (OR) =0.93; 95% Depend on period (CI) =0.8step 1–1.07]. Discover a comparable pattern out of RB pattern within this many years classification (Otherwise = 0.87; CI = 0.72–step one.06) pursuing the a noticeable increase in frequency regarding 1993 to 1998 (Otherwise = step three.29; CI = step one.25–8.62). At the same time, the brand new older age range exhibited a significant decline both for RP and you will RB with unadjusted ORs between 0.83 to help you 0.87 (find Desk 2). Analyses having fun with four age categories displayed no significant difference throughout the trend prior to now demonstrated. Style one of 15–16 and you may 17–18 yr old adolescents remained unchanged, while a bringing down pattern is noticeable for those aged 19–20, 21–22 and 23–24.
