A Community Health Ambassador (CHA) is a trusted member of the community who helps individuals to better access and coordinate their health care. The CHA assists identified individuals with the tasks of getting medical care, working on health goals (such as arranging care, planning healthy meals, or finding time to exercise), and to help them deal with 'real-life' issues that keep them from staying healthy. The CHA collaborates with other team members to conduct needs assessments to identify and respond to barriers to health and wellness. The CHA will support this research study and initiatives under the NIH-funded Massachusetts Community Engagement Alliance (MA-CEAL) Program. This study focuses on chronic diseases (e.g. diabetes and hypertension) intervention among residents of Boston’s public housing developments and Trinity Management. The CHA will work closely with the team and will serve as the main liaison for one of the intervention groups of the study. The CHA will cultivate relationships with participants to understand and support them in managing their chronic disease through healthy eating and physical activity. The CHA will connect with the participants in person and by phone. Collects and completes research data in a standardized format.
