title: Dietary responses to a hypertension diagnosis: evidence from the National Health and Nutrition Examination Survey (NHANES) 2007-2010.
abstract: Dietary modification has been shown to substantially reduce blood pressure among people with hypertension. This article uses data from the 2007-2008 and 2009-2010 cross-sections of the National Health and Nutrition Examination Survey (NHANES) to examine the extent to which a hypertension diagnosis can influence individuals' dietary choices. Several models were estimated to clarify the association of a hypertension diagnosis with dietary factors related to hypertension management. A comparison group of individuals at risk for developing hypertension was used. Results suggest that individuals who received a recent diagnosis of hypertension are more likely to have lower intakes of some dietary factors important in blood pressure management, including sodium. The results also highlight a discrepancy between added salt use and dietary sodium intake. While more recent hypertensive patients tended to consume lower levels of dietary sodium, patients diagnosed longer ago tended to use less added salt. Given that those diagnosed were more likely to have lower blood pressure profiles and improved diets, especially close to the time of diagnosis, the results of this study underscore the need for a prompt and accurate diagnosis of hypertension.
