| Measure | Time frame |
|---|---|
| Main Objective: Broad Goals The DO-HEALTH trial is designed to establish evidence for the role of vitamin D, omega-3 fatty acids, and a simple exercise program, both individually and as a combined intervention, in chronic disease prevention at older age. Objectives Main Objectives: • To improve healthy ageing in European seniors • To reduce healthcare costs via the implementation of effective and broadly applicable disease prevention interventions;Secondary Objective: Scientific Objectives: • To test whether 2000 IU vitamin D reduces risk of chronic disease in seniors compared to placebo • To test whether 1 g of marine omega-3 fatty acids (EPA+DHA) reduces the risk of chronic disease in seniors compared to placebo • To test whether a simple home exercise program reduces the risk of chronic disease in seniors compared to control (sham exercise performed 30 minutes 3 times a week) • To test whether there is an additive value of the 3 interventions combined as a multi-modal intervention in the reduction of chronic disease in seniors • To assess the comparative effectiveness of the interventions and to test whether and to what degree adherence modulates the effect of the 3 interventions on risk reduction of chronic disease in seniors • To assess the cost-benefit of the 3 interventions individually and in combination as a multi-modal intervention based on an objective health economic mode ;Primary end point(s): Primary Endpoints: (1) Bone: Incident non-vertebral fractures over 36 months (confirmed by X-ray or medical reports) (2) Muscle: Functional decline (assessed by Short Physical Performance Test Battery) (3) Cardiovascular: Systolic and diastolic blood pressure change (4) Brain: Cognitive decline (assessed by Mini Mental State Examination) (5) Immunity: rate of any infection;Timepoint(s) of evaluation of this end point: The evaluation of the primary endpoints will perform at baseline and then at the annual visits including the final visit after three years.

Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary Endpoints: To support the primary endpoints and extend to other organ systems: (1) Bone: incidence of hip fractures, incidence of new vertebral fractures (vertebral morphometry obtained with DEXA measurements), incidence of total fractures – (DEXA measurements), risk of bone mineral density decrease in the spine and hip (assessed by DEXA measurements) (2) Muscle: rate of falling (rate of any low trauma fall, rate of injurious falls, number of persons who fell), reaction time and grip strength, incidence of muscle mass decrease at the upper and lower extremities (DEXA measurements), musculoskeletal pain, dual tasking 10 meter gait speed (3) Cardiovascular: risk of incident hypertension (4) Brain: mental health decline, incident depression, dual tasking gait variability (5) Immunity: rate of any upper respiratory infection, incident flu-like illness, incident severe infections that lead to hospital admission (6) Bone/Cartilage: Arthritis: primary outcome for osteoarthritis will be severity of knee pain (KOOS) in those with symptomatic knee osteoarthritis, secondary outcomes for osteoarthritis will be: rate of knee buckling, NSAID use because of knee pain; number of joints with pain (7) Dental: decline in oral health, tooth loss (8) Gastro-intestinal: gastro-intestinal symptoms based on Rome III questionnaire (9) Glucose-metabolic: fasting glucose and insulin levels, QUICKI and HOMA index, body composition and increase in body fat in the trunk and extremities by DEXA (10) Kidney: decline in kidney function – by blood creatinine levels and estimated GFR (11) Global Health: quality of life, incident frailty, incident disability regarding activities of daily living, incident nursing home admissions, rate of acute hospital admissions, mortality Exploratory Endpoints: To support the primary endpoints, but have limited statistical power: (1) Bone: Incident repeat fractures (any non-vertebral in all participants, vertebral fractures and tota | — |
