Health related quality of life and physical activity in prison: a multicenter observational study in Italy

Inmates have a poorer health status than the general population. The physical activity is well know that improve the wellness of the people. This multicentric cross-sectional study aimed to assess the relationship between Quality of Life (QoL) and physical activity levels among Italian prisoners. Methods: Inmates from eight prisons compiled a questionnaire. The Metabolic Equivalent of Task (MET) was used to measure inmates’ weekly physical activity levels (MATwk). Their QoL was measured using two components of Short Form with 12 items (SF12): MCS (mental score) and PCS (physical score). Results: A total of 636 questionnaires were compiled. High level of MET was significantly (P<0.05) associated with both PCS (OR=1.02) and MCS (OR=1.03). The correlations between PCS, MCS vs. METwk scores were respectively significant: r=0.17 and r=0.10, P<0.05. The number of years of detention was associated to higher MET (OR=1.04 P<0.05). The presence of Physical Exercise Areas (PEAs) within Jails did not improve the QoL level.
