RP frequency was calculated of the breaking up just how many teens that have RP and the level of teens just who experienced at least one pregnancy (together with the individuals currently pregnant) increased of the 100. RB frequency while doing so was computed from the isolating the brand new amount of teenagers with RB therefore the quantity of adolescents exactly who experienced one or more livebirth multiplied of the 100. Deformalized questionnaire loads was basically applied whenever you are figuring the fresh frequency.
We made use of the ptrendi plan from inside the Stata13 to execute Cochran–Armitage screening to find the frequency trend for each and every age bracket using the newest chi-rectangular fact and conference new assumptions off an ingredient model. Cochran–Armitage shot was a modified Pearson’s chi-square test hence analyzes the fresh organization between digital (we.elizabeth. RP and you may RB) and you will ordinal (we.age. year and you may ages) kinds. Multivariate logistic regression investigation which have interaction effects getting years (we.elizabeth. age range playing with both three and you will four categories) and you may season was used while using constant maternity and beginning since the digital result details (we.age. yes if any). I counted the fresh pattern ranging from two straight survey decades to understand and this attacks got significant changes in incidence. Concurrently, i analyzed manner playing with season and you can socio-geographic (we.e. part, form of house, and you can wide range index) telecommunications per age group. For the purpose of beautiful looking Guadalajaran girl so it analysis, we made use of the around three classification age group as this try the fresh new simply categorization and that allowed an adequate number of cases.
Results
Among women old fifteen–24 years that have one maternity (letter = 7091), the vast majority (53.3%) was basically receive among the many twenty two–24 12 months olds. Despite the small ratio from teens grabbed by studies, the latest proportion from fifteen–18 year olds stated from the survey has grown over time away from eight.64% (letter = 107) in 1993 in order to % (n = 213) for the 2013 (look for Dining table step one).
Trend data for each age bracket
Frequency trends away from adolescents which have frequent maternity in the Philippines regarding 1993 so you can 2013 because of the generation. Caption: This shape gift ideas the fresh adjusted frequency out of repeated pregnancy having fun with decades teams that have (a) three and you may (b) four groups. Organizations making use of the three kinds include 15–18 years of age, 19–twenty one and you can twenty two–24 years of age just like the five kinds also 15–16 years old, 17–18 years of age, 19–twenty years old, 21–22 yrs old and 23–24 years old, just like the illustrated from the for every single line towards graphs. This new x-axis is the survey 12 months setup in chronological buy once the y-axis the weighted prevalence
Frequency manner off adolescents which have regular beginning in the Philippines out-of 1993 so you’re able to 2013 because of the age group. Caption: Which profile gifts the adjusted prevalence of repeated birth using ages communities having (a) around three and you will (b) four classes. Organizations using the around three categories were 15–18 years old, 19–twenty one and twenty-two–24 yrs old given that four categories plus 15–16 years old, 17–18 years old, 19–20 years old, 21–22 yrs . old and you will 23–24 years of age, just like the represented from the each line on graphs. Brand new x-axis ‘s the questionnaire season developed into the chronological acquisition while the y-axis the new adjusted incidence
Comparable overall performance was indeed found in the regression analysis. New RP trend certainly one of fifteen–18 12 months olds remained nearly unchanged round the all of the surveys regarding 1993 to help you 2013 [Chances proportion (OR) =0.93; 95% Confidence period (CI) =0.81–step one.07]. There can be a similar pattern out-of RB pattern contained in this age category (Or = 0.87; CI = 0.72–step 1.06) pursuing the an evident boost in prevalence from 1993 so you’re able to 1998 (Or = step three.29; CI = step one.25–8.62). On the other hand, the latest more mature age groups displayed a significant decline both for RP and you may RB which have unadjusted ORs anywhere between 0.83 to help you 0.87 (come across Dining table dos). Analyses having fun with five years categories showed zero significant difference regarding the fashion in earlier times demonstrated. Styles among fifteen–16 and 17–18 yr old teens remained intact, while a turning down development try obvious for those aged 19–20, 21–twenty two and you may 23–24.
