Description
Summary:This study aimed to explore the impact of health literacy on psychosocial and behavioural outcomes for people who were not at high risk of cardiovascular disease receiving a hypothetical blood pressure reading of 135/85 mmHg. We performed a secondary analysis of data from a national sample of Australians aged 40 to 50 years (n = 1318) recruited online. Health literacy was measured using the validated Newest Vital Sign (inadequate: 0–3; adequate: 4–6). Analysed outcomes included: willingness to increase exercise and accept medication; perceived severity; positive and negative affect; illness perceptions and impacts on life and motivation. Participants with inadequate levels of health literacy perceived a blood pressure reading of 135/85 mmHg to be less serious compared to individuals with adequate health literacy (Mean Difference [MD]:0.21; 95%CI 0.03–0.39; p = .024; d = 0.13), and reported less motivation to eat well (MD:0.44; 95%CI 0.31–0.58; p
