Abstract Background With the growing epidemic of Cardiovascular Disease (CVD) in sub-Saharan Africa, behavioural change interventions are critical in supporting populations to achieve better cardiovascular health. Population knowledge regarding CVD is an important first step for any such interventions. This study examined CVD prevention knowledge and associated factors among adults in Mukono and Buikwe districts in Uganda. Methods The study was cross-sectional in design conducted among adults aged 25 to 70 years as part of the baseline assessment by the Scaling-up Packages of Interventions for Cardiovascular disease prevention in selected sites in Europe and Sub-Saharan Africa (SPICES) – project. Data were collected using pretested semi-structured questionnaires, and respondents categorized as knowledgeable if they scored at least five out of six in the knowledge questions. Data were exported into STATA version 15.0 statistical software for analysis conducted using mixed-effects Poisson regression with fixed and random effects and robust standard errors. Results Among the 4372 study respondents, only 776 (17.7%) were knowledgeable on CVD prevention. Most respondents were knowledgeable about foods high in calories 2981 (68.2%), 2892 (66.1%) low fruit and vegetable intake and high salt consumption 2752 (62.9%) as CVD risk factors. However, majority 3325 (76.1%) thought the recommended weekly moderate physical activity was 30 min and half 2262 (51.7%) disagreed or did not know that it was possible to have hypertension without any symptoms. Factors associated with high CVD knowledge were: post-primary education [APR = 1.55 (95% CI: 1.18–2.02), p = 0.002], formal employment [APR = 1.69 (95% CI: 1.40–2.06), p < 0.001] and high socio-economic index [APR = 1.35 (95% CI: 1.09–1.67), p = 0.004]. Other factors were: household ownership of a mobile phone [APR = 1.35 (95% CI: 1.07–1.70), p = 0.012] and ever receiving advice on healthy lifestyles [APR = 1.38 (95% CI: 1.15–1.67), p = 0.001]. Conclusions This study found very low CVD knowledge with major gaps around recommended physical activity duration, diet and whether hypertension is asymptomatic. Observed knowledge gaps should inform suitable interventions and strategies to equip and empower communities with sufficient information for CVD prevention.
