“…Potentially relevant variables from Medical Conditions (MCQ), Cardiovascular Disease and Health (CDQ), Diabetes (DIQ), Osteoporosis (OSQ), Disability (DLQ), and Physical Functioning (PFQ) were identified for further analysis. The MCQ section provided self-and proxy-reported personal interview data on a broad range of health conditions and medical history for NHANES participants, with the section, generally modeled on the medical condition questionnaire section of the U.S. National Health Interview Survey (Miller et al, 2013). The CDQ section provided participant-level interview data on evaluating cardiovascular health and included questions to assess the presence of angina pectoris as defined by the Rose Angina Questionnaire (Rose, 1962).…”
