I determined the newest mean, practical deviation and prevalence speed regarding RP and you may RB a-year for every single generation

RP prevalence is computed by isolating the amount of teenagers having RP and the quantity of teens whom educated at least one pregnancy (together with those individuals currently expecting) increased because of the 100. RB incidence additionally are determined because of the separating the brand new amount of teens with RB super italian pretty hot girls together with amount of adolescents exactly who knowledgeable a minumum of one livebirth multiplied from the 100. Deformalized survey weights have been applied while you are figuring this new frequency.

We utilized the ptrendi bundle during the Stata13 to execute Cochran–Armitage evaluation to select the incidence trend for every age bracket playing with the new chi-rectangular figure and you may conference the newest presumptions from an ingredient model. Cochran–Armitage try was a changed Pearson’s chi-rectangular attempt and this assesses the fresh new organization between digital (we.elizabeth. RP and you will RB) and ordinal (i.age. year and you can many years) kinds. Multivariate logistic regression data that have correspondence effects for ages (we.e. age range having fun with one another three and you will four groups) and you can season are used when using constant maternity and beginning while the digital result details (we.elizabeth. sure if any). I measured the new development between one or two successive survey age to recognize which periods got high changes in frequency. In addition, i analyzed manner using 12 months and you can socio-geographic (i.elizabeth. part, variety of household, and you can riches directory) correspondence for each age group. For the true purpose of which analysis, we utilized the three classification generation because this are the new only categorization and that desired an adequate number of cases.


Certainly one of feminine aged fifteen–24 years that have a minumum of one pregnancy (n = 7091), a large proportion (53.3%) were discovered one of the twenty-two–24 year olds. Regardless of the quick ratio regarding teens seized because of the studies, the brand new ratio out-of 15–18 12 months olds stated from the survey has increased over the years regarding 7.64% (n = 107) in 1993 to help you % (letter = 213) in 2013 (discover Desk step one).

Trend study for every age bracket

Prevalence styles off teenagers that have repeated pregnancy about Philippines out of 1993 so you can 2013 because of the age group. Caption: It figure presents new weighted incidence out of constant pregnancy playing with years teams that have (a) three and you can (b) four categories. Teams by using the three categories become 15–18 years of age, 19–twenty-one and twenty-two–24 years old given that four groups as well as 15–16 years of age, 17–18 yrs . old, 19–2 decades old, 21–twenty-two years of age and you will 23–24 yrs old, once the depicted by each line towards graphs. This new x-axis is the survey 12 months created into the chronological acquisition since y-axis the latest adjusted incidence

Prevalence manner out-of teens which have repeated birth regarding the Philippines out-of 1993 to 2013 by the generation. Caption: So it profile gifts the fresh weighted incidence out of repeated delivery using years teams that have (a) about three and (b) five classes. Communities utilising the around three categories include 15–18 yrs . old, 19–21 years old and twenty-two–24 years old due to the fact five groups along with fifteen–sixteen years of age, 17–18 years old, 19–twenty years dated, 21–22 yrs old and you will 23–24 years old, once the portrayed because of the for each and every range into the graphs. The new x-axis is the survey year create from inside the chronological buy due to the fact y-axis brand new weighted incidence

Equivalent overall performance was indeed found in the regression study. The fresh new RP development one of 15–18 seasons olds stayed almost intact around the all of the studies from 1993 so you’re able to 2013 [Potential proportion (OR) =0.93; 95% Trust interval (CI) =0.8step 1–step 1.07]. There is the same trend out-of RB pattern in this ages category (Or = 0.87; CI = 0.72–step one.06) following the an evident boost in incidence away from 1993 so you’re able to 1998 (Otherwise = step three.29; CI = step 1.25–8.62). In addition, the fresh elderly a long time showed a serious decline for RP and you may RB that have unadjusted ORs between 0.83 so you’re able to 0.87 (pick Table 2). Analyses playing with four many years kinds exhibited no significant difference regarding the styles prior to now demonstrated. Trends certainly one of 15–sixteen and 17–18 year old teens stayed undamaged, while a bringing down development is actually apparent for those old 19–20, 21–twenty two and you can 23–24.
