Preventing Cognitive Decline: The CITA GO-ON Multi-domain Intervention Study (CITA GO-ON)
Effectiveness of a Lifestyle Multidomain Intervention to Prevent Cognitive Decline in the Basque Country. GOIZ ZAINDU Gipuzkoa - CITA GO-ON Study
The GOIZ ZAINDU Gipuzkoa - GO - ON Study is an intervention trial to evaluate the efficacy of dementia prevention strategies in cognitively frail people. It is a large-scale randomized controlled trial in over 1000 older adults between 60 and 85 years old with increased CAIDE risk score (≥6), non-demented but with low performance in at least one of three brief cognitive tests. Participants will be randomized to receive standard health advice (SHA-control) or a multidomain intervention (MM-Int) consisting of 1) Risk factor control (vascular factors, polypharmacy); 2) Cognitive training, 3) Physical activity, 4) Dietary changing program, and 5) emotional counseling and social engagement.
The primary aim is to demonstrate a 20% reduction in the proportion of subjects who decline in their NTB performance (z score) after 24 months in the intervention group compared to the controls.
Secondary aims include: 1) Analyze cost-effectiveness; 2) Show a beneficial effect of the intervention on functional abilities, quality of life, and depressive and anxiety symptoms; 3) Investigate the impact of a lifestyle intervention on aging. In this sense, biological samples and neuroimaging studies will be collected to allow exploratory investigations on aging mechanisms, amyloid imbalance, tau pathology, epigenetics, neuroinflammation, vascular dysfunction, lipid dysregulation, white matter disintegration, cognitive and brain reserve.
This protocol is participant-centered, empowering citizens since the recruitment process to gain access to knowledge about their dementia risk status via web or by phone and then decide to participate. Intervention activities have also taken into account participants' perspective with the design of easy-to-use and appealing activities (e.g., using a self-administered at-home physical activity program such as VIVIFRAIL© and EXERCITA© cognitive training materials that have been developed, taking into account the Basque Country population's cultural, linguistic and educational particularities; and diet and nutritional workshops with famous chefs to learn innovative and attractive healthy recipes).
The GO-ON trial may shed light on the tools that people need to fulfill the expectation of an active, healthy dementia-free aging. These include digital tools that in the COVID19 pandemic have shown to be effective in removing distance barriers. GO-ON uses them to give support and expand the possibilities to clinical assessment settings and intervention delivery. The digital part of the intervention may expand preventive actions to small rural areas, including digital socialization.
GO-ON Study, which starts in summer 2021, is the first large-scale lifestyle intervention trial in Southern Europe that takes part in the WORLDWIDE FINGERs network and will help answer whether the FINGER results can be replicated. The intervention design has been made on the basis that if proven to be efficacious, it may be easily applied at a Public System-level to guarantee a rapid and easy translation of research results to Primary Care settings and people homes.

- History within the last 2 years of treatment for primary or recurrent malignant disease, excluding non-melanoma skin cancers, resected cutaneous squamous cell carcinoma in situ, basal cell carcinoma, cervical carcinoma in situ, or situ prostate cancer with normal prostate-specific antigen posttreatment
- Recent (< 3 months) bone fracture.
- History of hip fracture, joint replacement, or spinal surgery in the last 6 months

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Standard health advice (SHA-control)
The participant will receive verbal information of risk factors and information, reassessment, and written materials regarding approved recommendations on active and healthy aging on topics such as diet, physical activity, cognitive training as well as risk factor control following the state of the art and published guidelines by the Department of Health of the Basque Government/ Basque Country Public Health System (Osakidetza) and the WHO (Guidelines for risk reduction of cognitive decline and Dementia and the "Guidance on person-centered assessment and pathways in primary care - ICOPE").
Participants in this group will receive the best standard health care from their primary care and specialist health teams according to already established routines as well as usual social services assessments and care as needed.
|
|
Experimental: Multidomain intervention (MM-Int)
Participants in this group will receive the same verbal and written recommendations as to the ones in the SHA-Control group but then they will perform a 2 year structured program with periodic individual and group visits regarding 1) Risk factor control (vascular factors, polypharmacy); 2) Cognitive training, 3) Physical activity, 4) Dietary changing program and 5) emotional counseling and social engagement.

Measure Description |
Time Frame |
---|---|---|
Global Cognitive performance
Time Frame: up to 2 years
|
Cognitive performance will be assessed with the Neuropsychological Test Battery modified (NTBm) (Harrison J. et aet al.ch Neurol 2007). The NTBm consists of 9 validated components:NTBm Cognitive global, executive function, memory, processing speed scores will be obtained. Composite cognitive z-scores based on the results from all single tests will be calculated. Single z-scores will be calculated using baseline mean and standard deviations of the study sample and, for each composite score, single z-scores will be averaged. Higher scores suggest better performance. |

Performance in each cognitive domain
Time Frame: up to 2 years

NTBm Cognitive global, executive function, memory, processing speed scores will be obtained. Composite cognitive z-scores based on the results from all single tests will be calculated. Single z-scores will be calculated using baseline mean and standard deviations of the study sample and, for each composite score, single z-scores will be averaged. Higher scores suggest better performance. b. Change in specific cognitive domains will be assessed by the difference in pre-and postintervention scores in episodic memory, executive function and processing speed and visuospatial function z-scores. |

Incremental Cost-Utility Ratio (ICUR)
Time Frame: up to 2 years
|
To estimate the cost-effectiveness of the intervention program the Incremental Cost-Utility Ratio (ICUR) between muntidomain intervention group and regular health advice group. The incremental cost-utility ratio (ICUR) will be estimated by dividing incremental cost (Ca-Cb) by incremental utility (Ua-Ub). The time horizon was the patient's lifetime. A 3% discount rate will be applied to costs and effectiveness. Since the main economic impact of dementia is related to the care required as patients become dependent, a societal perspective will be used. |

Amsterdam questionnaire for Instrumental Activities of Daily Living (A-IADL-Q)
Time Frame: up to 2 years
|
The Amsterdam IADL Questionnaire (A-IADL-Q) is an adaptive and computerized questionnaire designed to assess impairments in instrumental activities of daily living (IADL) in (early) dementia.
The questionnaire is completed by a caregiver, such as a relative or friend.
(Sikkes SA et al. 2012).

Change in perceived Quality of life - EQ-D-5L scale
Time Frame: up to 2 years
|
The EQ-5D-5L (Herdman M. et al. 2011) essentially consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. |

The HADS is a fourteen-item scale that generates: Seven of the items relate to anxiety and seven relate to depression.
