Participants then completed 24\u2010hour ambulatory BP monitoring and separate awake and asleep urine collections. The change in urinary sodium excretion rate with stress was defined as the difference in urinary sodium excretion rate before and after stress. The awake\u2010to\u2010asleep ratio of the urinary sodium excretion rate and systolic BP dipping were calculated from the 24\u2010hour urine and BP measurements.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">In an adjusted model including age, sex, race, ethnicity, body mass index, mean systolic BP, mean diastolic BP, parental history of hypertension, fasting glucose, and 24\u2010hour creatinine clearance, a smaller stress\u2010induced urinary sodium excretion rate was associated with a lower awake\u2010to\u2010asleep ratio of urinary sodium excretion rate (n=180, B=0.2253 [95% CI, 0.0490\u20130.4016]).
