Clustering of CVD biological risk factors was defined as presenting three or more of CVD biological risk factors (including dyslipidaemia, diabetes, hypertension, overweight/obesity and central obesity); physical activity: moderate to vigorous intensity physical activity at least once a week was classified as ‘Yes’ in physical activity status.
