DO-HEALTH

• July 2012 to July 2017

• Europe randomized controlled clinical trial (2x2x2 factorial design = 2 levels of vitamin D, two levels of Omega 3, two types of exercise)

• 70+ year old seniors

• 1 page DO-HEALTH summary Feb 2012

• 8 treatment groups with the 3 interventions alone or combined:

• interventional Vitamin D dosage: 2,000 IU versus placebo.

  • They anticipate many participants will take 800 IU (standard of care), thus the amount might be as much as 2800 IU down to 800 IU

• Omega 3: 1 g (EPA+DHA) per day versus placebo.

• exercise: two interventional programs focused either on “muscle strength” or “joint mobility”. Both programs performed 3 times/ week for 30 minutes

• calcium supplements will be allowed up to a dose of 500 mg per day max (plus diet intake)

• no indication on Magnesium intake

• Compliance: individual follow-up with study personnel every 3 months by phone call or clinical visit to assess new health-related events, ARs, major lifestyle changes, assess compliance and motivate participants

  • Compliance might be enhanced by marking it on the calendar for taking weekly
  •       1 pill taken about once a week instead of having to remember to take a pill every day.
  • no indication of any increase of vitamin D for those who have medications which reduce the vitamin D response
  • no indication of giving more vitamin D for those seniors who are obese, have dark skin, or who have medical reasons for having a low response to vitamin D

• no loading dose. Other studies indicate that the benefit of the vitamin D might not even start in the first year. - see references below

• Sponsored by European Commission within the European 7th Framework Program for Research and Technological Development.

  • The Universities involved and three industrial sponsors (DSM Nutritional Products, Roche and Nestlé Health Science) are co-funding the study.
