The results Venezuela were weighted by gender, age, and regions. Risk factors Results: Data from 3414 participants (77% of recruited), 52.2% female, mean age of 41.2 ± 15.8 years, Cardiovascular disease Tobacco were analyzed. CMRF adjusted-prevalence were: diabetes (12.3%), prediabetes (34.9%), hypertension Dyslipidemia (34.1%), obesity (24.6%), overweight (34.4%), abdominal obesity (47.6%), underweight (4.4%), hyperc- Diabetes holesterolemia (19.8%), hypertriglyceridemia (22.7%), low HDL-cholesterol (63.2%), high LDL-c (20.5%), Obesity daily consumption of fruits (20.9%) and vegetables (30.0%), insufficient physical activity (35.2%), anx- iety (14.6%) and depression (3.2%) symptoms, current smoker (11.7%), and high (≥ 20%) 10-year fatal cardiovascular risk (14.0%). CMRF prevalence varied according to gender, age and region of residence. Conclusions: Cardiometabolic risk factors are highly prevalent in Venezuelan adults. This situation can be affected by the severe socio-economic crisis in the country. The joint action of different stakeholders to implement public health strategies for the prevention and treatment of these risk factors in Venezuela is urgently needed. © 2020 Primary Care Diabetes Europe.
