Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 2-year change from baseline in global cognitive composite score derived from subtest scores from the Neuropsychological Test Battery (NTB) that includes 15-Word Verbal Learning Test delayed recall, DDST 90 seconds, WAIS digit span backwards, and semantic fluency. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints 2-year change from baseline in: a) individual cognitive test performances, representing memory (15-Word Verbal Learning Test delayed recall), processing speed (Digit Symbol Substitution Test 90 seconds) and attention and executive functioning (WAIS digit span backwards, semantic fluency); b) Instrumental activities of daily living using the Amsterdam Instrumental Activity of Daily Living Questionnaire (A-IADL-Q); c) Quality of life using the 5-level EuroQol-5D (EQ-5D-5L); d) Modifiable dementia risk using LIfestyle for BRAin health (LIBRA); e) Intervention specific outcomes: • Physical activity: grip strength, physical activity (SQUASH questionnaire), sedentary behavior (LASA Sedentary Behavior Questionnaire) and sarcopenia (SARC-F Sarcopenia Questionnaire. For participants at UMCG only: a physical activity diary (Physical Activity Record) • Cognitive training: cognitive function (semantic fluency test), metamemory (Metamemory in Adulthood Questionnaire); • Cardiovascular: blood pressure, cholesterol (total, HDL, LDL + triglycerides), blood glucose (HbA1C), medication adherence (Hill-Bone Medication Adherence Scale); • Dietary counselling: nutritional intake (Traqq app), adherence to Dutch dietary guidelines (Dutch healthy diet index); • Sleep counselling: sleep behavior (7 day sleep diary), insomnia (Insomnia severity index); • Stress management: mindfulness (Five Facet Mindfulness Questionnaire), perception of stress (Perceived Stress Scale); • Social activities: perceived social support (Lubben Social Network Scale), emotional and social loneliness (De Jong Gierveld Loneliness Scale). f) Blood-based biomarkers for Alzheimer*s disease (Aβ42/40, p-tau), axonal damage (NfL), astrocytes activity/injury or stress (GFAP) and brain plasticity (BDNF). | — |
