PLOS ONE

Dear Farrukh Ishaque Saah,

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.

The statistical analysis needs specific attention where you are reporting on logistic regression analysis.

Please submit your revised manuscript by Oct 23 2020 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're 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.

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). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results.

5. Review Comments to the Author

Reviewer #1: The aim of this study was to assess the impact of waiting job in upscale restaurant on the health and well-being of waiters. Additionally, the authors assessed sleep quality and its associated factors among waiters in upscale restaurants. This is a very interesting study and I have just a minor comment related to sleep quality predictors. The authors should add in the Limitations section that also the level of physical activity, which was not assesesd in this study, could also be a predictor of sleep quality.

Reviewer #2: PONE-D-20-07362

The manuscript entitled ‘Sleep quality and its predictors among waiters in upscale restaurants: A descriptive study in Accra Metropolis’ aimed to assess sleep quality and its associated factors among waiters in upscale restaurants in the Accra Metropolis of Ghana’. It seems that the methodology and the result are adequate, but some revisions are required. There are some comments as follow.

- First page of introduction is just about growing fast food restaurants and the importance of competition between restaurant and so on (which is not your main goal). The introduction needs a revision in order to highlight the sleep quality more and the factors affecting that. The reasons why this happens might to summarize in a single paragraph. Please summarize the introduction.

- How this study would help and be of importance? Please mention in the introduction more clearly and in brief.

- The last two sentences of introduction are saying two different things. Mention the overall and primary goal of your study.

- There is a main point regarding sampling method. How did you choose the restaurants (what kind of sampling methods)? The result can generalize to the whole population of waiters if we use probability sampling methods. But it is not clear how you chose restaurants.

- Please mention the full phrases of abbreviations in the last raw of tables. What are COR and AOR in the table 4, for example.

- What statistical analysis is used (the results in Table 4)? Mention in the statistical analysis part (just mentioned in the abstract). As you used logistic regression, so mention odds ratio (OR) in the statistical analysis and also use the abbreviation of OR in the manuscript. Why most of the cells are empty in the Table 4?
