Review of " Prevalence and Associated factors of Teenage Childbearing among Ethiopian
Women’s using Semi-parametric and Parametric PH and AFT Models"
The topic of this study is very relevant and could give substantial information regarding
adolescent pregnancies and its implication.  It is important sector to find out the factors
associated with adolescent pregnancies. This paper will therefore be of general public health
interest in women's health issues.
The paper could be better if Author could clarify on the following points.
Broad comments
1. In the abstract in method section already explained the statistic tools used, however there is a
repletion in the result. I think the main finding is lost in statistical explanation, it would be more
informative if the result focused on prevalence and associated factors of adolescent pregnancy
more clearly.
2. In line 47 sentence in introduction section " The first child's birth is the main outcome of the
reproductive process” is not clear, what does a it means? I think the sentence structure could be
rearranged for more information.
3. In line 50-51 and 56 please correct grammatical error
4. The introduction section I think its inadequate and does not explain enough about the back
ground and the rationale behind the study and the literature should be more extensive.
5. In line 55- 69 in this paragraph objective should be clearly mentioned
6. In line 57-59-63 “Adolescent pregnancy and childbearing have distinct and significant
negative effects on society, the world, and individuals ……”. Please give the reference
7.  In line 70-71 this belongs to method “To demonstrate the factors that affect how long it takes
adolescents in various countries to start having children, we conducted a survival analysis..”
8. The line 81-85 this belongs to result section.
9. The line 86- 89 belongs to discussion
10. In the method section I think it needs to explain why the mentioned statistical tools are
appropriate for the study
11. In line106 and 107 method section it would be nice which are the “demographic characters”
considered for further analysis and why
12. In line191 and 192 I think the selection of model, if further explained would be better
13. In line 224-227 please rearrange the sentence to make it more clear
14. Discussion should explanation on why the finding in your research, why it is different or
similar compared to the existing literature. What you find new in your research or you did not
find anything new? What is the contribution to knowledge from your research? Is your objective
met? Did this research have to deviate from the methodology or need to change your process
while collecting data - discuss why either to yes or no to the previous question?
15. The Discussion needs to be clearer and stronger. Discussion should summarize only the
major findings interpreting what the findings mean and why. Why it is different or similar
compared to the existing literature What is the contribution to knowledge from this research? Is
the objective met? Does it deviate from the methodology or need to change the process while
collecting data - discuss why either to yes or no to the previous question?
16. Discussion should also explain the implications for policies and programs from these
findings which help to draw the conclusions. For e.g. the research's main finding indicates that
women delivering in private institution have higher risk of caesarean delivery, researchers can
discuss on this: why do they think that make the case.
17. In conclusion section information is inadequate, please state specific findings and indicating
its implications in a more specific way.
