Note: Based on 10,528 adults alive at the end of 2009, reported having at least one chronic condition (cardio-metabolic, musculoskeletal, or respiratory condition). All analyses accounted for complex survey design of the Medical Expenditure Panel Survey. Asterisks represent statistically significant group differences based on chi-square tests. CM: Cardio-metabolic; Musc.: musculoskeletal; Resp.: respiratory; Wt: weighted; OR: odds Ratio; CI: confidence Interval.
