Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The ICOPE Brazil study aims to understand aging trajectories in Brazil, especially healthy aging trends based on intrinsic capacity, a collective of mental and physical capacities one may have to maintain their functional ability to execute daily life activities. Tests and questionnaires will be applied to collect data on mobility capacity, cognitive capacity, nutritional status, vision, and hearing (sensorial) capacities, and mental health. These assessments are in consonance with what the World Health Organization proposed in the Integrated Care for Older People Program (ICOPE). Participants will be followed up for three years, and the primary outcomes of interest are loss of intrinsic capacity, mobility impairment, cognitive impairment, incident depressive symptoms, loss of functional ability, incident frailty, incident sarcopenia, incident falls, hospitalization, multimorbidity, and mortality.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The ICOPE Brazil study is a prospective, longitudinal cohort study designed to investigate the trajectories of aging among older adults in Brazil, with a particular emphasis on healthy aging as defined by the World Health Organization (WHO). The central conceptual framework guiding this study is "intrinsic capacity," a multidimensional construct encompassing an individual's physical and mental capacities that contribute to the maintenance of functional ability in later life.

Data collection will involve the administration of standardized tests and structured questionnaires to assess five core domains of intrinsic capacity: mobility, cognitive function, nutritional status, sensory capacities (vision and hearing), and psychological well-being. These domains reflect the recommendations outlined in the WHO's Integrated Care for Older People (ICOPE) program, which aims to promote healthy aging and support the functional ability of older populations globally.

Participants will be followed for a total duration of three years, with periodic assessments to monitor changes over time. The primary outcomes of interest include: decline in intrinsic capacity, mobility impairment, cognitive impairment, onset of depressive symptoms, loss of functional ability, incident frailty, incident sarcopenia, incidence of falls, hospitalizations, multimorbidity, and all-cause mortality. Data generated from this study will inform public health strategies, clinical guidelines, and policy development for aging populations in Brazil and other similar settings.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Community-dwelling older adults

Population Community-dwelling people aged ≥ 60 years registered in the participating primary health care units, and domiciled in their respective coverage area. Participants do not have to be active patients to be invited.

We will create a random order from the lists of users registered in each health care unit involved in the project to invite participants. This approach ensures a systematic random sampling strategy to avoid participants' enrollment by convenience and its related selection bias.

Participants will be invited via telephone or home visits, following the order established by the randomization list, until we reach the minimum expected number of participants for each center. For centers that need to enroll participants from two or more health care units to achieve the minimum expected sample size of 202 participants, it is necessary to consolidate the user lists from these units into a single list before randomization.
