DASH-Sodium Trial in Adolescents

The Camp DASH study is a controlled trial. the aim of which is to compare the effect of two
dietary patterns and two levels of sodium intake on blood pressure and blood lipids in
adolescents in the upper third of distribution for blood pressure. The study also assesses
whether influences on blood pressure and blood lipids of dietary interventions vary according
to sex, race/ethnic groups, baseline levels, and other personal characteristics. The proposed
dietary interventions of DASH dietary patterns and sodium reduction have been shown to be
effective in lowering blood pressure in adults. The two dietary patterns are based on the
Dietary Approaches to Stop Hypertension (DASH) trial in adults. They are a Usual diet typical
of what many American adolescents eat, and a DASH‐type diet. The DASH diet is rich in fruits,
vegetables, and low‐fat dairy foods and low in saturated fat and total fat compared to the
Usual diet. The two sodium levels are High reflecting current US consumption and Low
reflecting current recommended intake levels. Weight will be held constant by adjusting
energy intake. The study participants will live in a residence hall on the Purdue campus
where all food and beverages will be provided, and meals and snacks will be supervised.
