  1. 1. The DASH Diet: A measure of compliance to a structured remedy for lowering Blood Pressure DHBCI DIY Assignment By: Jason Paulson
  2. 2. D.I.Y. Problem:  I have uncontrolled hypertension.  Tried prescriptions in the past, though discontinued use to try and treat with nutrition and exercise.  Unsuccessful, so it‟s time to try a structured, proven approach for managing hypertension.  Purpose of the study: measure compliance to DASH Diet, to help indicate likelihood of using model as a remedy in future.  Hypothesis: complying with the DASH Diet will result in significant reductions of blood pressure
  3. 3. Theoretical Framework  Cognitive Dissonance Theory- (Festinger „57)  Two dissonant cognitions: 1) I eat too many salt-laden foods, excess salt increases blood pressure. 2) I have HTN, I don‟t want to take BP meds. If Unaddressed, dissonant cognitions lead to “psychological discomfort” e.g. ”I need to start eating higher proportion of whole foods, and less processed „relatively-healthy foods‟”.
  4. 4. How Do I Measure DASH Compliance?  I ascribed each of the eight DASH categories with a 5-point scale designating specific values of servings for each group (based of a 3,100kcal/day diet). For instance, „Grains‟ Grading criteria: Grains- (minus two points if majority are refined) 5 pts. = 10-13 more servings 4 pts. = 8-9 servings or 14-15 servings 3 pts. = 6-7 servings or >15 servings 2 pts. = 4-5 servings 1 pt. = 2-3 serving 0 pts. = 0-1 servings
  5. 5. BP/HR Readings & Percentage Adherence Day Blood Pressure (BP) Heart Rate (HR) Percent Adherenc e Regular Diet, Day 1 139/71 62 67.5% Regular Diet, Day 2 135/78 60 32.5% Regular Diet, Day 3 141/82 74 55% DASH Diet, Day 1 125/73 80 77.5% DASH Diet, Day 2 130/69 69 75% DASH Diet, Day 3 133/70 68 69%
  6. 6. Systolic Blood Pressure 160 155 150 145 140 135 130 125 R² = 0.067 Morning SBP Mid-day SBP Evening SBP Linear (Mid-day SBP) 120 115 110 Reg. Diet, Day Reg Diet,SBPDASH Diet,SBP 2 SBP 3 SBP Reg. Diet,SBPDASH Diet, Day 1 Day 1 Day 2 Day 3 SBP DASH Diet, Day
  7. 7. Did it Work? Regular Diet: (Pre-Intervention measures)  Compliance- 52%  Avg. BP- 138/77 Avg. HR- 65 DASH Diet:  Compliance- 74%  Avg. BP- 129/71 Avg. HR- 72
  8. 8. What I learned/ Insights Gained  It‟s cheaper to follow DASH than my usual patterns  Just like the base of evidence suggests, DASH is effective; I can manage my BP if I really apply!  Weak study design  I didn‟t factor caffeine into my scoring criteria  i.e. Ignored major confounder
  9. 9. Disappointments with DASH  There is no distinguishing between meat, fish, poultry, nuts, and beans.  Only one serving recommended of nuts, seeds, and legumes. -This discourages eating a variety of foods from this important food group.
