PLOS ONE

Dear Mr Obasohan,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

ADDITIONAL ACADEMIC EDITOR COMMENTS: An expert in this field handled your manuscript and found it interesting, but they have listed several comments and concerns that need to be addressed. These comments include, but are not limited to, the need to provide a better rationale in the introduction about the study design and there seems to be some methodological details lacking in the methods section.

We would appreciate receiving your revised manuscript by Oct 20 2019 11:59PM. When you are ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter.

To enhance the reproducibility of your results, we recommend that if applicable you deposit your laboratory protocols in protocols.io, where a protocol can be assigned its own identifier (DOI) such that it can be cited independently in the future. For instructions see: http://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). This letter should be uploaded as separate file and labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. This file should be uploaded as separate file and labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. This file should be uploaded as separate file and labeled 'Manuscript'.

Please note while forming your response, if your article is accepted, you may have the opportunity to make the peer review history publicly available. The record will include editor decision letters (with reviews) and your responses to reviewer comments. If eligible, we will contact you to opt in or out.

We look forward to receiving your revised manuscript.

Kind regards,

Frank T. Spradley

Reviewer #1: Title section: probably would need to exclude "Factor and logistic regression analyses"

This study used a cross sectional study, but as the title indicates, the study tried to assess the impact of some variables. Is that right? Please modify your title.

Abstract section: It is recommended not to use abbreviations in this section. In addition, you said that this problem has not been explored in Nigeria, how can you be sure that?

Take home message should be added in conclusion

Introduction section:

1. Page 3 (Line 65, 72), please correct as SSA, provide their full text first for SBP and DBP

2. Page 3, 4. Please rewrite the sentence beginning with between blood pressure and end with BMI (Line, 82, 83)

3. Page 4, Line 91. Where is elsewhere?

4. Page 5, Line 102-107. Taking about factor analyses, I think this paragraph should be stated in methodology section

5. In general, when we state the introduction section, we have to state in the following way;

6. General description of the problem under study including its meaning, burden/magnitude of the problem from global to local and from past to current, whose is affected, where, when, the consequences of the problem, causes, what has been done before by the Government of Nigeria to reduce this problem, factors attributable of the problem identified by previous research works.

Methods section:

1. Page 5, Line 115. Description of the study setting and design were not included

2. Page 6, Line 122. Describing about DDF is better if you move it in to variables measurement and operational definition section

3. Page 7. You estimated a final sample size of 440, then, why you included 530 participants. Is your sampling technique being cluster sampling, if so, you need to account the design effect while calculating your sample size?

4. Many sections of the methodology were not appeared. Sampling procedure, study population, exclusion and inclusion criteria, variable measurements, operational definition, and others. Please follow the scientific paper writing format as others did.

5. Where were your data collectors, their profession and educational background, the language used to prepare the data collection tool….

Results section:

1. Page 10. You did not state the results of sociodemographic and other variables. No interest,..

2. Define others in respective tables (Table, 1, 2).
