The teen birth rate is used in comparing regional variation in teen pregnancies, but local teen brith rates are not always available in this study the percentage of all births that are to teens was evaluated for its utility as a surrogate for the teen birth rate.
Rank correlation and sensitivity and specificity analyses Results.
The Spearman rank correlations between percentage of teen births (PTB) and teen birth rate (TBR) were. 995. 906, and. 841 for the 3 age groups suggesting that it may be reasoonable to employ PTB to prioritize zip codes.
Zip codes with upper quartile levels percentages of teen births identified zip codes with upper quartile levels of TBR with a sensitivity of 83.8%, 68.8%, and 65% ; a false-positive rate of 2.1%, 8.6%, and 10% ; and a positive predictive value of 89.3%, 67.6%, and 67.5% for the age groups 10 tough 14,15 through 17, and 18 19 years.
The percentage of births to teens is a useful surrogate for teen birth rate in California, especially among younger teenagers.
