Background Text messages are useful for health promotion and can be modified during public health emergencies. Purpose Describe how we developed and implemented a physical activity (PA) text messaging component within a faith-based intervention, modified the text message content in response to the COVID-19 pandemic and evaluated participants’ perceptions of the modified text messages. Research Design and Study Sample PA promotion text messages were delivered to predominately Spanish-speaking, churchgoing Latino adults ( n = 284) in Los Angeles, California. In 2020, we modified the messages to disseminate COVID-19-related information and support and share virtual PA resources. Data Collection and Analysis We analyzed quantitative and qualitative survey data to gauge participants’ experiences with the text messages. Results COVID-19 related text messages were a feasible, acceptable addition to a PA intervention for a sample of Latinos. Conclusions Throughout the pandemic, the messages enabled continued communication and support for PA and protection from COVID-19 in a population at high-risk of health inequities.
