Outcomes
Primary Outcome Measures
Recurrence frequency of benign paroxysmal positional vertigo
The intervention group will receive tablets containing 400IU cholecalciferol and 500mg of elemental calcium as calcium carbonate twice daily (CAVID CHEWABLE TAB, Takeda Pharmaceuticals) for 12 months when the initial serum vitamin D is decreased. The compliance will be determined by the percentage of consumed tablets from the delivered tablets during the follow-up period. Discontinuation of the supplementation due to adverse effects or other reasons will be registered using the telephone interview together with the primary outcome date. Participants in the control group will not have any intervention or placebo. They will not be allowed to take vitamin D or calcium as supplements during the follow-up. The primary outcome measure is the recurrence of BPPV after one year. Data on recurrences will be collected using a monthly telephone interview, and the patients will be asked to visit the clinic whenever they have the symptoms of BPPV. All the recurrences of BPPV will be included.
Secondary Outcome Measures
Changes in serum 25-hydroxy vitamin D level
In intervention group, the baseline vitamin D status of participants will be checked. And the level of 25-hydroxyvitamin D level will be rechecked at 2 months from the recruitment and at the end of the follow-up.
Falling frequency
To determine the supplementation of the vitamin D and calcium carbonate is effective to decrease falling frequency.
Fracture frequency
To determine the supplementation of the vitamin D and calcium carbonate is effective to decrease fracture frequency.
Quality of life
To determine the supplementation of the vitamin D and calcium carbonate is related to quality of life using UCLA-dizziness questionnaire
Recurrence rate of benign paroxysmal positional vertigo
The intervention group will receive tablets containing 400IU cholecalciferol and 500mg of elemental calcium as calcium carbonate twice daily (CAVID CHEWABLE TAB, Takeda Pharmaceuticals) for 12 months when the initial serum vitamin D is decreased. The compliance will be determined by the percentage of consumed tablets from the delivered tablets during the follow-up period. Discontinuation of the supplementation due to adverse effects or other reasons will be registered using the telephone interview together with the primary outcome date. Participants in the control group will not have any intervention or placebo. They will not be allowed to take vitamin D or calcium as supplements during the follow-up. The primary outcome measure is the recurrence rate of BPPV after one year. Data on recurrences will be collected using a monthly telephone interview, and the patients will be asked to visit the clinic whenever they have the symptoms of BPPV. All the recurrences of BPPV will be included.
