Background: Although walkability is known to be associated with obesity and hypertension through increased physical activity; data on cardiovascular risk factors (especially in the Europe) are scarce. We assessed the relationship between neighbourhood walkability and cardiometabolic factors (including obesity, hypertension, the blood lipid profile, and serum glycated haemoglobin (HbA1c) levels) among adults living in northern France., Methods: Data were extracted from the ELISABET study database (2011-2013). The participants (aged between 40 and 65) resided in or around the cities of Lille and Dunkirk. For each residential address, we determined a neighbourhood walkability index (using a geographic information system) and the Walk Score®. Multilevel linear and logistic models were used to assess the relationships between neighbourhood walkability on one hand and body mass index (BMI), obesity, blood pressure, hypertension, serum HDLC, LDL-C, triglyceride and HbA1c levels, and physical activity level on the other., Results: 3218 participants were included. After adjusting for individual and neighbourhood variables, we found that a higher neighbourhood walkability index was associated with a lower BMI (-0.23 kg.m -2 ; 95% confidence interval (CI) [-0.44;-0.01] for a one interquartile range (IQR) increment), a lower systolic blood pressure (-1.66 mmHg; 95% CI [-2.46;-0.85] per IQR), a lower prevalence of hypertension (% of increase: -7.12, 95% CI [-13.56;-0.52] per IQR), and a higher prevalence of moderate or high physical activity (% of increase = 6.9; 95% CI [1.2;12.72] per IQR). The walkability index was not significantly associated with other cardiovascular risk factors. Similar results were observed for the Walk Score®., Conclusion: Our results showed that residence in a more walkable neighbourhood was associated with a lower prevalence of vascular risk factors. Promoting neighbourhood walkability might help to improve the population's cardiovascular health., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Luc Dauchet contributed to an expert report commissioned by Lille European metropole “Rapport d’expertise à propos de la localisation de la piscine du projet d’aménagement de la gare Saint Sauveur à Lille” [Expert report on the location of the swimming pool in the Saint Sauveur station development project in Lille] but did not receive any personal fees.
