The risk factors for CVD include behavioural factors, such as tobacco use, an unhealthy diet, harmful use of alcohol and inadequate physical activity, and physiological (metabolic) factors, including high blood pressure (hypertension), high blood cholesterol and high blood sugar or glucose. Both kinds of factor are linked to underlying social determinants and drivers. This module focuses on the behavioural risk factors and provides information on: • tobacco use, unhealthy diet, insufficient physical activity and harmful use of alcohol as important contributors to CVDs • behavioural change, brief interventions for counselling and key points for motivational interviewing • the theory of the 5As for brief interventions, as well as sample brief interventions for each risk factor, using the 5As. Target users of this module This module is intended for trainers of primary health care workers, including physicians, nurses, and other health workers. Primary care workers should be trained on the risk factors and counselling approaches, adapting to local customs, culture and context. NCD programme managers may also use it for planning purposes.
