Effectiveness of Health Communication on Depression Elderly in Ho Chi Minh City

The goal of this clinical trial is to learn if a community-based health education and communication program helps prevent and reduce depression in older adults living in Ho Chi Minh City. It will also evaluate how the program affects quality of life and caregiver stress. The main questions it aims to answer are: 1. Does the health education program improve knowledge, attitudes, and practice regarding depression among older adults and their primary caregivers? 2. Does the program reduce depression scores (measured by GDS-30) and improve quality of life in older adults compared to standard care? 3. Does the program help lower caregiving burden and stress among primary caregivers? Researchers will compare an intervention group (older adult and caregiver pairs who receive the education program) to a control group (pairs who receive standard community health care). Participants in the intervention group will: * Attend 5 group education sessions (45-60 minutes each) covering early depression detection, sleep hygiene, nutrition, physical activity, stress management, and caregiver support. * Complete questionnaires at the start and end of the program to measure depression symptoms, quality of life, caregiving burden, and health knowledge.
