I determined new indicate, practical departure and you will frequency price from RP and you will RB per year for each age group

RP prevalence try determined by the splitting the amount of teens which have RP additionally the number of teens who knowledgeable a minumum of one maternity (also those already expecting) multiplied because of the 100. RB incidence additionally is computed from the separating brand new amount of teenagers with RB plus the number of teenagers just who knowledgeable a minumum of one livebirth multiplied by 100. Deformalized questionnaire loads was indeed used when you are calculating the incidence.

I made use of the ptrendi plan when you look at the Stata13 to perform Cochran–Armitage assessment to select the prevalence pattern for every single age group having fun with brand new chi-rectangular fact and you can conference brand new assumptions of an additive design. Cochran–Armitage sample try a modified Pearson’s chi-rectangular take to which analyzes brand new connection anywhere between digital (we.e. RP and you will RB) and you will ordinal (we.elizabeth. seasons and you may many years) categories. Multivariate logistic regression study having correspondence outcomes having age (we.elizabeth. age range having fun with each other around three and you will five categories) and you may seasons are presented while using regular pregnancy and you will beginning since the binary lead details (we.elizabeth. sure or no). I measured the brand new pattern between a couple of consecutive questionnaire decades to spot and this symptoms got high alterations in prevalence. As well, we reviewed manner playing with 12 months and you may socio-geographic (we.e. part, types of home, and you can money list) telecommunications for each and every age bracket. For the intended purpose of this analysis, i used the around three category age group that try new simply categorization and that greeting an adequate number of cases.


Certainly feminine old fifteen–24 age having at least one pregnancy (n = 7091), a large proportion (53.3%) had been receive among the many 22–24 season olds. Despite the small ratio away from teens seized because of the studies, the proportion regarding fifteen–18 seasons olds stated from the questionnaire has grown over time regarding eight.64% (letter = 107) into the 1993 to help you % (letter = 213) within the 2013 (see Table step 1).

Development research each age bracket

Frequency fashion of adolescents that have frequent maternity regarding the Philippines of 1993 in order to 2013 of the generation. Caption: It shape presents the latest adjusted prevalence from repeated maternity playing with years organizations which have (a) around three and you can (b) five groups. Groups utilising the three categories is 15–18 yrs old, 19–twenty one and you can twenty two–24 yrs . old once the five categories including fifteen–sixteen years of age, 17–18 years old, 19–20 years old, 21–twenty-two yrs old and 23–24 yrs . old, while the portrayed by the for each range with the graphs.

Incidence manner from teens with repeated beginning on Philippines off 1993 so you can 2013 by the age bracket. Caption: This figure presents the weighted prevalence regarding constant delivery playing with decades groups with (a) about three and you may (b) four kinds. Communities utilizing the about three groups are fifteen–18 years of age, 19–21 years old and twenty-two–24 years of age as five groups in addition to fifteen–16 years old, 17–18 yrs . old, 19–two decades dated, 21–22 years of age and you can 23–24 years old, since represented by for each line to your graphs. The newest x-axis ‘s the survey seasons created from inside the chronological buy just like the y-axis new adjusted prevalence

Comparable abilities were based in the regression analysis. New RP hva er en postordrebrud hottestwomen.net trend certainly one of fifteen–18 year olds stayed about undamaged all over all the surveys away from 1993 to help you 2013 [Opportunity proportion (OR) =0.93; 95% Rely on period (CI) =0.8step 1–step 1.07]. There’s the same pattern out-of RB development within many years category (Otherwise = 0.87; CI = 0.72–1.06) pursuing the a noticeable upsurge in prevalence out-of 1993 in order to 1998 (Otherwise = 3.29; CI = 1.25–8.62). As well, the fresh new older age range showed a significant decline for both RP and you will RB which have unadjusted ORs anywhere between 0.83 in order to 0.87 (pick Desk dos). Analyses using five decades categories demonstrated no factor regarding trend in past times described. Style certainly one of 15–sixteen and you will 17–18 year old teens stayed unchanged, while a lowering trend try obvious for these aged 19–20, 21–22 and you may 23–24.
