Round 1

Reviewer 1 Report

According to Table 1, >60% of the patients had taken Vit D - supplements:

Please indicate in addition  the Vit D dose range.

Line 258 pp: Please discuss the dosing of Vit D-supplements: enough - or in (de)crease dosings?

How long did patients take the supplements - did they really take them??

Should dosing generally  be in(de)creased: yes or no? Precautions?

Author Response

Many thanks for your comments and suggestions.

The supplementation of Vitamin D was not instituted as part of this study. Participants self-reported their vitamin D supplements with doses ranging from 100IU to 800IU per day.

Compliance was not recorded as we did not initiate supplementation therefore I can not accurately comment on this or the duration of therapy prior to recruitment, unfortunately.

So this leaves it difficult to say if their doses should be adjusted. I can recommend that those deficient need depletion and avoidance of supra- supplementation?

Many thanks,

Avril

Reviewer 2 Report

The manuscript determines the relationship of vitamin D status in older adults with hospital admission and emergency department attendance.

Authors found inverse associations of vitamin D with hospital admission. According to the author, vitamin D supplementation will improve the disease states of cognition, bone health, and hypertension.

The author presents a nice piece of work that will recommend vitamin D supplementation in older adults. In my opinion, this work is acceptable.

  • The title and abstract reflect the content of the work.
  • The introduction section requires some improvement. Please add the role of vitamin D in cognition, bone health, and hypertension.
  • The authors have performed good statistical analysis to find an association between vitamin D and cognition, bone health, and hypertension in older adults.
  • Discussion and explanations of the obtained results were made correctly.
  • The selected topic is interesting. The work is properly documented.

Author Response
