Studies have shown that regular physical activity and healthy dietary patterns can help reduce blood pressure. This study aimed to determine the dietary patterns and physical activity levels of older women with hypertension.</p> Methods <p>This cross-sectional study involved 334 older women with hypertension who were attending hospitals and health care centers affiliated with Ardabil University of Medical Sciences. A convenience sampling method was utilized. Anthropometric measurements, the International Physical Activity Questionnaire-Short Form (IPAQ), and the Food Frequency Questionnaire (FFQ) were employed to gather data.
