Abstract 4156: Differences in Healthy Lifestyle Characteristics among Persons with Normal Blood Pressure versus Prehypertension
Background: Identifying differences in healthy lifestyle (HL) characteristics among persons with prehypertension versus normal blood pressure (BP) levels may reinforce intervention programs aimed at preventing the development of hypertension.
Methods: Data for 7741 persons aged ≥ 20 with BP measured in the 1999–2002 National Health and Nutrition Examination Survey were analyzed. Differences in HL (i.e., normal body mass index [BMI, 18–24.9 kg/m2], not smoking, adequate physical activity [≥30 min/day], and moderate or no alcohol consumption [≤2 drinks/day for men and ≤1 for women]) were examined by BP status (normal, prehypertension, and hypertension). Gender, race/ethnic, and education level differences in HLs were also examined among those with prehypertension.
Results: Overall, 39.7% of persons had normal BP and 31.3% had prehypertension. Only 10% of the sample had all 4 HL characteristics. After adjustment for gender, race, education and age, persons with prehypertension were less likely than were persons with normal BP to have a normal BMI [adjusted odds ratio (AOR)=0.69; 95% confidence interval (CI)=0.60– 0.78], to drink moderately/ no at all (AOR=0.78; 95% CI=0.72– 0.85), and to have all 4 HL characteristics (AOR=0.70; 95% CI=0.55– 0.90). There were no differences in the odds of not smoking or being physically active. Among persons with prehypertension:
women were less likely to be active and more likely to moderately/ not drink and have all 4 HL characteristics than were men;
African Americans were less likely to be physically active but more likely to moderately/ not drink than were whites;
Mexican Americans were less likely to have a normal BMI level, to be physically active, and to have all 4 HL characteristics but more likely to not smoke than were whites;
persons with less education were less likely to not smoke, be active, or to have all 4 HL characteristics.
Conclusions: Several differences in modifiable lifestyle factors were observed between persons with prehypertension versus normal blood pressure levels. However, the prevalence of healthy lifestyle factors is sub-optimal for all groups regardless of hypertension status.
