I calculated the imply, simple deviation and you may frequency price out-of RP and you can RB annually each generation
RP frequency try determined from the separating the amount of adolescents having RP as well as the quantity of teenagers just who experienced one or more maternity (plus those individuals already expecting) multiplied of the 100. RB frequency on top of that is determined because of the separating the newest amount of teenagers which have RB while the amount of adolescents just who experienced a minumum of one livebirth increased from the 100. Deformalized questionnaire weights was used when you are figuring the new incidence.
I utilized the ptrendi package during the Stata13 to do Cochran–Armitage tests to search for the incidence development each age group using new chi-rectangular fact and fulfilling the fresh new assumptions away from an ingredient model. Cochran–Armitage take to is an altered Pearson’s chi-square decide to try and that assesses this new connection ranging from digital (we.e. RP and you will RB) and ordinal (we.age. year and you will decades) classes. Multivariate logistic regression data having telecommunications outcomes having many years (we.age. age groups playing with both about three and four kinds) and season are presented while using frequent pregnancy and you may birth while the binary lead details (i.elizabeth. sure or no). I measured the brand new trend ranging from two successive survey years to understand and that periods got significant changes in frequency. At exactly the same time, i analyzed manner using 12 months and you may socio-geographical (i.age. part, variety of household, and you may wide range directory) communication each generation. With regards to this studies, i made use of the three group generation because this is actually the latest merely categorization and therefore invited a sufficient number of instances.
Show
Certainly one of women aged fifteen–24 age with one or more maternity (letter = 7091), a large proportion (53.3%) had been receive among twenty two–24 seasons olds. Despite the quick proportion off kissbrides.com proceed the link right now adolescents captured of the surveys, the ratio out of 15–18 seasons olds stated throughout the questionnaire has grown over time out-of 7.64% (n = 107) from inside the 1993 so you’re able to % (n = 213) inside the 2013 (discover Table step one).
Trend studies for each and every age group
Prevalence styles from adolescents which have constant maternity throughout the Philippines of 1993 to 2013 by the age group. Caption: This shape merchandise the fresh adjusted prevalence off repeated maternity using decades groups having (a) around three and you will (b) four kinds. Groups using the about three kinds is 15–18 years old, 19–twenty one and you may 22–24 years old just like the five kinds as well as fifteen–16 yrs old, 17–18 years old, 19–twenty years old, 21–22 years old and you can 23–24 yrs old, as portrayed because of the for each line on graphs. The brand new x-axis is the survey 12 months establish when you look at the chronological buy while the y-axis brand new adjusted prevalence
Prevalence manner of teens having constant beginning regarding the Philippines of 1993 so you’re able to 2013 because of the age group. Caption: That it figure gifts brand new weighted incidence out-of repeated birth having fun with years communities that have (a) about three and you may (b) four kinds. Teams with the about three classes become 15–18 yrs . old, 19–21 years old and 22–24 yrs old given that four kinds as well as fifteen–16 yrs . old, 17–18 yrs old, 19–2 decades old, 21–twenty-two years of age and you can 23–24 yrs old, given that illustrated because of the for every single range with the graphs. The new x-axis is the survey seasons set-up in the chronological order because y-axis the new weighted frequency
Similar performance were found in the regression analysis. The latest RP trend certainly fifteen–18 12 months olds stayed around unchanged around the all the surveys out-of 1993 so you’re able to 2013 [Chances proportion (OR) =0.93; 95% Count on interval (CI) =0.8step 1–step one.07]. There’s a similar trend of RB development within this decades classification (Otherwise = 0.87; CI = 0.72–step one.06) following the an evident upsurge in frequency from 1993 to 1998 (Or = 3.29; CI = 1.25–8.62). Concurrently, the brand new elderly a long time presented a critical decline both for RP and you will RB which have unadjusted ORs ranging from 0.83 to help you 0.87 (come across Dining table 2). Analyses using four decades classes showed zero factor in the style in the past demonstrated. Styles certainly one of 15–sixteen and you will 17–18 yr old adolescents remained intact, whereas a lessening trend is actually apparent for those aged 19–20, 21–twenty two and you will 23–24.
