This course will introduce the concept of vulnerability and the health workers roles in meeting the health needs of vulnerable population groups. Vulnerable populations usually experience disparities in access to health care and have poorer health status than the population as a whole. Factors that predispose people to vulnerability, outcomes of vulnerability and the cycle of vulnerability will be described. Public health interventions are designed to help break the cycle of vulnerability and eliminate health disparities at all community levels. Additionally the process of learning to work with vulnerable population will be highlighted. Vulnerable populations include the women and children, poverty and homelessness, minority and immigrants, racial and ethnic minorities, social exclusion/Isolation, and sexual minorities. It may also include rural residents, who often encounter barriers to accessing healthcare services. The vulnerability of these individuals is enhanced by race, ethnicity, age, sex, and factors such as income, insurance coverage (or lack thereof), and absence of a usual source of care. Their health and healthcare problems intersect with social factors, including housing, poverty, and inadequate education.
