In 2012, 25.5% of US adults had multiple (≥2) diagnosed chronic conditions among 10 different conditions: arthritis, cancer, chronic obstructive pulmonary disease (COPD), coronary heart disease, current asthma, diabetes, hepatitis, hypertension, stroke, and weak or failing kidneys.[1,2] Compared with adults without chronic conditions, adults with multiple chronic conditions have worse health-related quality of life, higher health care costs, and increased risk of death.[3–5] Using 2018 National Health Interview Survey (NHIS) data, we provide estimates of the prevalence of single and multiple chronic conditions among US adults.
