Sodium intake in a cross-sectional, representative sample of New York City adults
American journal of public health, 2014•ajph.aphapublications.org
Objectives. We estimated sodium intake, which is associated with elevated blood pressure,
a major risk factor for cardiovascular disease, and assessed its association with related
variables among New York City adults. Methods. In 2010 we conducted a cross-sectional,
population-based survey of 1656 adults, the Heart Follow-Up Study, that collected self-
reported health information, measured blood pressure, and obtained sodium, potassium,
and creatinine values from 24-hour urine collections. Results. Mean daily sodium intake was …

Objectives. We estimated sodium intake, which is associated with elevated blood pressure, a major risk factor for cardiovascular disease, and assessed its association with related variables among New York City adults.
Methods. In 2010 we conducted a cross-sectional, population-based survey of 1656 adults, the Heart Follow-Up Study, that collected self-reported health information, measured blood pressure, and obtained sodium, potassium, and creatinine values from 24-hour urine collections.
Results. Mean daily sodium intake was 3239 milligrams per day; 81% of participants exceeded their recommended limit. Sodium intake was higher in non-Hispanic Blacks (3477 mg/d) and Hispanics (3395 mg/d) than in non-Hispanic Whites (3066 mg/d; both P < .05). Higher sodium intake was associated with higher blood pressure in adjusted models, and this association varied by race/ethnicity.
Conclusions. Higher sodium intake among non-Hispanic Blacks and Hispanics than among Whites was not previously documented in population surveys relying on self-report. These results demonstrate the feasibility of 24-hour urine collection for the purposes of research, surveillance, and program evaluation.
