Reviewer's report:
Thank you for the opportunity to review this interesting manuscript. It explores factors influencing
use of modern contraceptive method. The topic is interesting and overall, the report is well written.
However, there are some aspects in the paper that must be addressed.1.Reviewing and commenting the manuscript was somehow difficult as new line numbering start
on every page and pages didn't have numbers. Authors are encouraged to use the authors guide.
2.Title contains abbreviation- (PMA). It is better to write it in full words to enhance clarity.3.Background section, Line 21 reads as "…among sexually unmarried…" I suppose it is "sexually
active unmarried"
4.Data analysis on method section-
*It was mentioned variables with significant association from the univariate analysis wereincluded in a 2-level multivariate logistic regression. What was the significance level used inunivariate binary logistic regression to include a variable for multivariate logistic regression? It isworth mentioning the significance level used for both univariate and multivariate logistic
regression.
5.Result section
*Line 41 shows the age range as 15-19. I assume it is 15-49 as shown in table 1*Contraceptive use among age range 30-39, crosscheck what is written in results section vs.shown in table 1. There seems to be an error.*It states the result of the two-level multivariate logistic regression is shown in Table 2. However,this data is not in table 2.
6.Discussion section compared modern contraceptive use with the national figure. However, it fell
short to give explanation for the difference in rate of modern contraceptive use among unmarriedwomen. Modern contraceptive use among unmarried women was 28% in DHS 2018 findingcompared to 13.3% in this study. what are possible explanations for this difference?
7.Comments about non-significant findings- this is one of the situations where non-significant
findings could be as important as significant findings. In this study, interventions expected toincrease use of contraceptive method did not have impact. For example, visitation by healthworker about FP did not show statistically significant impact on modern contraceptive use. What
does this tell about the effectiveness of this intervention? Would it indicate the need to evaluate the
quality of this intervention? The same is true for facility visit with or without FP talk, average
number of days FP supported facilities are opened, presence of facility that provide free FPservices in the community and number of FP supported facilities.
8.Conclusions are not entirely based on the findings from the study.
*The study did not specifically assess sexual activity, levels of unwanted pregnancies and illegalabortions among adolescents and young adults.*It also recommends to increase access, supply/demand of health commodities. However, this wasnot assessed in the study.
*The study should capitalize on community level factors affecting contraceptive uptake. As
mentioned in the background, other studies have already looked at influence of sociodemographic,fertility intentions and misconception on contraceptive use.
9.What are possible limitations of this study that readers should take into account?
*What would be the impact of merging married women with those living with partner as ifmarried? Is there existing evidence that show difference in utilization of contraceptive methodbetween these two groups?*The dependent variable, use of modern contraceptive methods, was documented based onindividual woman's response as 'Yes' without confirmation of actual method use. Could there beover estimation of contraceptive use due to social desirability bias?
