The purpose of this study is to explore strategies to effectively implement senior-center-based multilevel lifestyle interventions adapted from evidence-based lifestyle interventions to promote physical function and quality of life in diverse older adults with Type 2 Diabetes (T2D).
Aim 1: Work with community stakeholders including individuals with T2D, family members, and senior center staff to adapt evidence-based lifestyle interventions, and develop implementation strategies.
Aim 2: Conduct a senior-center-based 6-month pre- and post-pilot study and collect recruitment, enrollment, retention rate, fidelity, program satisfaction and experience, and stakeholder acceptance using quantitative and qualitative data.
Aim 3: Assess the preliminary health-related responses to the intervention in older adults with T2D in the 6-month trial.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Lifestyle intervention group | Experimental | The study team will assess improvements in physical function assessed by the short physical performance battery and other health-related measures (diabetes knowledge, self-efficacy, social support, physical activity, diet consumption, HbA1c, and quality of life). |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Adapted Look Ahead Lifestyle Intervention | Other | Participants will be educated about improving healthy lifestyles involving physical activity and healthy eating to improve physical function and improve glycemic control. |
| Measure | Description | Time Frame |
|---|---|---|
| Feasibility of conducting study | Feasibility refers to how feasible to conduct the study. In this study, feasibility will be assessed by data such as participant recruitment, enrollment, education session attendance, and retention rate. | Baseline, 3, 6, and 12 months |
| Acceptability | Acceptability refers to how well an intervention will be received by the target population and the extent to which an intervention might meet the needs of the target population. Acceptability will be assessed through qualitative interview with participants to explore their experience, and perceptions with the intervention. | Baseline, 3, 6, and 12 months |
| Measure | Description | Time Frame |
|---|---|---|
| Body Weight | Measured in pounds with participant in light clothes and without shoes | Baseline, 3, 6, and 12 months |
| Systolic Blood Pressure | Sitting blood pressure will be measured after at least five minutes of rest. |

The deidentified quantitative data from the 15 participants such as demographics and clinical data could be shared upon request from the applicant after the study findings have been published in peer-reviewed journals.
The biospecimen collected at the senior center will be transported to the School of Nursing Biobehavioral Laboratory by the laboratory staff or the PI in a dry ice container on the same day of data collection.
Data may be shared after peer-reviewed journal publication after study completion or as summary results on ClinicalTrials.gov

| Baseline, 3, 6, and 12 months |
| Diastolic Blood Pressure | Sitting blood pressure will be measured after at least five minutes of rest. | Baseline, 3, 6, and 12 months |
| Short Physical Performance Battery (SPPB) | The SPPB is a series of physical tests used to assess a person's lower extremity function. SPPB scores range from zero to 12 possible points. A higher score indicated better physical performance. | Baseline, 3, 6, and 12 months |
| Grip Strength | Grip strength will be measured in both hands, and the dominant hand will be recorded. | Baseline, 3, 6, and 12 months |
| Glycated Hemoglobin (HbA1c) | HbA1c is a blood test that is used to assess and monitor the average level of glucose over the past two to three months. | Baseline, 3, 6, and 12 months |
| Lipid profile | It is a blood test that measures the levels of fats and fatty substances in the blood. The following measurements in the profile will be assessed: cholesterol, LDL (low-density lipoprotein) cholesterol, HDL (high-density lipoprotein) cholesterol, and triglycerides. | Baseline, 3, 6, and 12 months |
| IPAQ-12 | This scale contains 12 items that are a self-reported measure of physical activity. Scores are typically expressed in minutes per week. Higher scores indicate higher levels of physical activity, whereas lower scores suggest sedentary or low activity levels. | Baseline, 3, 6, and 12 months |
| MoCA | MoCA is a 30-point questionnaire that tests various cognitive domains, including memory, attention, language, abstraction, executive functions, visual skills, calculation, and orientation. The score ranges from 0-30, and higher score indicates better cognitive function. | Baseline, 3, 6, and 12 months |
