We calculated the fresh new indicate, basic departure and you can prevalence price of RP and you may RB a year for every single age group
RP frequency try calculated by dividing the amount of teens with RP additionally the quantity of adolescents exactly who knowledgeable one or more maternity (plus the individuals currently pregnant) increased of the 100. RB incidence https://kissbrides.com/tr/guam-kadinlar/ at the same time are calculated because of the isolating new quantity of teens that have RB together with level of teenagers which experienced at least one livebirth multiplied by the 100. Deformalized survey loads had been applied while calculating the new incidence.
We used the ptrendi package when you look at the Stata13 to perform Cochran–Armitage evaluating to select the frequency development per age group using this new chi-rectangular statistic and fulfilling the assumptions off an ingredient design. Cochran–Armitage try try a modified Pearson’s chi-rectangular shot and this assesses the fresh new connection anywhere between digital (i.age. RP and you will RB) and ordinal (we.e. year and you will years) kinds. Multivariate logistic regression investigation with correspondence effects to possess decades (i.elizabeth. age groups playing with one another around three and you may five classes) and season is used when using regular maternity and you will delivery since the binary lead details (we.age. yes if any). I mentioned the development between a couple consecutive survey ages to determine hence periods had extreme changes in prevalence. Concurrently, i examined trends playing with 12 months and you may socio-geographic (i.e. region, form of quarters, and you will money directory) communication for every generation. For the intended purpose of so it data, we made use of the about three class age bracket since this is this new merely categorization which invited a sufficient number of instances.

Certainly one of female aged 15–24 many years with a minumum of one pregnancy (letter = 7091), the great majority (53.3%) was indeed discover one of several twenty two–24 season olds. Despite the short ratio regarding adolescents seized by studies, this new ratio from 15–18 season olds advertised on questionnaire has grown over time regarding 7.64% (letter = 107) inside the 1993 so you’re able to % (n = 213) from inside the 2013 (pick Table 1).
Trend analysis per age bracket
Incidence trends out of adolescents with constant pregnancy from the Philippines regarding 1993 to 2013 from the age group. Caption: That it profile merchandise the latest weighted incidence from repeated maternity having fun with ages communities that have (a) three and (b) four groups. Communities making use of the about three kinds tend to be 15–18 yrs old, 19–21 years old and you will twenty-two–24 years old because the five classes together with fifteen–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, because portrayed by the for every line into graphs. This new x-axis is the survey seasons created inside the chronological order just like the y-axis brand new weighted incidence
Incidence style out of teens that have repeated birth about Philippines out of 1993 to help you 2013 because of the age bracket. Caption: Which profile gift ideas the adjusted incidence out-of constant beginning having fun with ages teams which have (a) around three and (b) four classes. Organizations utilizing the around three kinds become fifteen–18 yrs . old, 19–twenty one and you can twenty two–24 years of age once the five categories and 15–sixteen years old, 17–18 years of age, 19–20 years dated, 21–22 years old and you can 23–24 years of age, due to the fact portrayed of the per line with the graphs. The new x-axis ‘s the questionnaire season arranged in chronological purchase as the y-axis the adjusted incidence
Equivalent results have been based in the regression research. The fresh RP pattern one of fifteen–18 12 months olds stayed very nearly intact round the all studies from 1993 so you can 2013 [Opportunity proportion (OR) =0.93; 95% Rely on period (CI) =0.81–step 1.07]. There can be an equivalent pattern away from RB development within this years class (Otherwise = 0.87; CI = 0.72–1.06) following the an obvious boost in incidence of 1993 so you can 1998 (Or = step 3.29; CI = step one.25–8.62). Simultaneously, the fresh new elderly age range shown a serious refuse both for RP and RB with unadjusted ORs ranging from 0.83 so you can 0.87 (look for Dining table dos). Analyses using five age categories demonstrated no significant difference on the manner previously described. Fashion one of 15–sixteen and you can 17–18 yr old adolescents stayed undamaged, while a lowering pattern is actually visible of these aged 19–20, 21–twenty two and 23–24.
