3-year Global Cognitive Change Restricted to ARIC Participants |
Mean change in global cognitive function in standard deviations from baseline to year 3 estimated from a linear mixed-effects model. Global cognitive function was defined as a factor score derived from the completion of a neurocognitive testing battery. The ACHIEVE study administers a neurocognitive testing battery annually, which includes the following cognitive tests: Delayed Word Recall, Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Word List, Incidental Learning, Logical Memory I and II, Word Fluency, Animal Naming, Boston Naming, Trail Making Test A and B, Digit Span Backwards, and Digit Symbol Substitution. Factor analytic methods use all items from all tests in the battery to generate a single score of global cognitive function. The global cognitive function factor score has a minimum of -5 and a maximum of 4. Lower scores denote worse cognitive function. Stratified by recruitment type ARIC vs De Novo. |

Social Engagement |
Change from baseline to year 3 in social engagement, as assessed by the Cohen's Social Network Index (SNI) questionnaire, which asks about the number of people the participant has regular contact with (at least once every 2 weeks) within each of 12 different possible settings/types of contacts (e.g., relatives, church members, neighbors, etc.). Social engagement is quantified by evaluating the total number of people in the social network across all 12 settings/roles. |

Loneliness |
Change from baseline to year 3 in loneliness, as assessed using the University of California Los Angeles (UCLA) Loneliness Scale questionnaire. The UCLA Loneliness Scale is interviewer administered and consists of 20 items that participants rate using a 4-point Likert scale; 9 positively worded items are reverse-coded, and the average scores range from 1 to 4, with higher score indicating greater expression of loneliness. |

Physical Function: Lower Extremity Function |
Change from baseline to year 3 in lower extremity function, as assessed using the Short Physical Performance Battery (SPPB), which includes timed tests for usual gait speed, balance, and the ability to rise from a chair. Each of the 3 tests is scored from 0 to 4, with higher scores reflecting better lower extremity physical performance, and the total SPPB score is calculated as the sum of the 3 tests, with a range of 0 to 12, with higher scores reflecting better physical performance. |

Physical Function: Grip Strength |
Change from baseline to year 3 in grip strength (kilograms of force) measured by a hand-held dynamometer, based on the best of two trials with the participant's preferred or best hand. |

Physical Function: Physical Activity |
Change from baseline to year 3 in physical activity measured by accelerometry. Participants will use a wrist-worn device that is worn continuously for 7 days after baseline, and 7 days after each annual follow up. This measures the intensity, duration, and frequency of physical activity. |

Self-reported Physical Ability |
Change from baseline to year 3 measured using the falls and mobility questionnaire which records living circumstances, self-reported physical ability, fatigue, and falls. |

Self-reported Physical Activity |
Change from baseline to year 3 in self-reported physical activity measured using the Baecke Physical Activity Questionnaire, which includes questions about frequency of exercise/sports and leisure activities to generate composite scores of sports during leisure time (continuous measure between 1 and 5) and leisure time excluding sports (continuous measure between 1 and 5). |

Depressive Symptoms |
Change from baseline to year 3 in depressive symptoms, as assessed by the Center for Epidemiological Studies Depression Scale (CES-D). The CES-D is an interviewer-administered scale that consists of 12 items which participants rate using a 3-point Likert scale; 2 positively worded items are reverse-coded. The first 11 items are summed to create a total score ranging from 0 to 22, with higher scores indicating greater expression of depression. The 12th item is a rating of hopelessness that is not included in the total score. |

Hearing Handicap |
Change from baseline to year 3 measured on the Hearing Handicap for the Elderly Screening Version (HHIE-S) questionnaire, which is a 10-item questionnaire developed to assess how an individual perceives the social and emotional effects of hearing loss; scores range from 0 to 40, with higher scores suggestive of greater hearing handicap |

Intervention Feedback |
A questionnaire that gathers feedback about the study intervention that participants are receiving. Participants rate how strongly they agree or disagree with a series of statements about the ACHIEVE study intervention they received. |

Physical Health |
Change from baseline to year 3 as assessed using the RAND-36, which is an interviewer-administered scale measuring a person's perceptions of their health and health-related quality of life; the physical component score is an algorithmically derived score with a normative mean of 50 and standard deviation of 10 (range 0 to 100), where higher scores indicate better physical health. |

The cognition memory domain was defined as a factor score derived from the completion of a neurocognitive testing battery. The cognitive tests for the memory domain include Delayed Word Recall, CERAD Word List, Incidental Learning, and Logical Memory I and II. These tests have an underlying commonality or factor, that is unable to be directly measured, and factor analytic methods use items from the tests noted to generate a single overall memory score. The cognition memory domain factor score has a minimum of -5 and a maximum of 4. Lower scores denote worse cognitive function. |
