Patterns of Physical Activity Among Women Incarcerated in Jail.

The physical and mental health benefits of physical activity in all populations are well established. In 2019, incarcerated women at a Southwest county jail were observed during "recreation time," a time when physical activity is encouraged, to identify the proportion of women who participated in recreation time and their physical activity levels. During observed recreation times, 28% of women attended; 56% were sedentary, 4% engaged in vigorous physical activity, and approximately 40% walked or performed similarly moderate physical activity.

Adaptation of the System for Observing Play and Recreation in Communities (SOPARC) for the Measurement of Physical Activity in Jail Settings.

Over 9 million people are incarcerated in jail each year, but physical activity has not been assessed among incarcerated populations. Measuring physical activity in the jail setting is complicated as current physical activity measurement tools are not designed for use inside jail facilities. Therefore, we adapted an evidence-based physical activity measurement tool, the System for Observing Play and Recreation in Communities (SOPARC), to assess physical activity within a jail facility.
