Technical Abstract: The objective of this study is to examine differences between self-reported intakes of sodium, trans-fat, and total fat among hypertension (HTN) subgroups of participants in Mississippi Communities for Healthy Living nutrition education intervention. Dietary intake was measured using a food frequency questionnaire adapted for the Lower Mississippi Delta. Systolic blood pressure (BP) was converted to a categorical variable based on the ATPIII guidelines (normal less than 120mmHg, pre-HTN 120-139mmHg, stage I 140-159mmHg, and stage II greater than 160mmHg). ANOVA was used to test nutrient intake differences between HTN subgroups. LSD post hoc tests were evaluated for within group differences. Sodium, trans-fat, and total fat intake were significantly different between HTN subgroups (F (3,260)=2.95, p=.033; F (3,260)=3.84, p=.01; F (3,260)=3.01, p=.031, respectively). Participants with Stage 1 and 2 HTN consumed significantly less sodium than participants with normal BP. Individuals with pre-, stage 1 and 2 HTN consumed significantly less trans-fat then those with normal BP (M=3.71, SD=2.34, p=.001; M=3.79g, SD=2.224, p=.046; M=2.91g, SD= 2.109, p=.004, respectively). Total fat intake was significantly less in pre-HTN (M=70.34, SD=40.85, p=.015) and stage 2 HTN (M=61.57 g, SD=41.73, p=.016) compared to those with normal BP (M=86.32, SD=48.55). Prior research indicates lifestyle changes may likely occur after HTN diagnosis. Regardless, mean daily intake of sodium and fats were higher than recommended dietary allowances for all groups, and mean intakes for stage 2 HTN came closest to recommended amounts. Previous quality/quantity of nutrition education is unknown in this sample, but attempting to quantify this may be of benefit for future studies.
