Intervention strategies in changing nutritional behavior: a systematic review
Intervention strategies in changing nutritional behavior: a systematic review

Summary/Abstract: One of the factors that enhance quality of life is nutritional behaviour. Food is an im-portant factor that influences physical, but also psychological human development. In this respect, researchers find necessary an interdisciplinary approach, which to emphasize the importance of people's dietary habits. The purpose of this systematic review is to provide a summary of the nutrition education interventions for participants aged between 15 and 65. Electronic databases such as CINAHL (EBSCOhost), ProQuest and Science Direct were used and explored for articles that were published between 2010 and 2016. There were included 23 studies, summing up a number of 10.318 participants. Interventions represent group and/or personalized approaches; a common one is that of nutrition education, de-livered through trainings; other studies have tailored approaches, such as motivational interview, individual cognitions, self-regulation processes, coaching sessions, or motiva-tional text messages. The interventions are based on theoretical models such as Health Belief Model, Social Cognitive Theory, Self-Determination Theory, Cognitive- Behavioural Theory, Self-Regulation Theory, Planned Behaviour Theory, Trans- theoretical Model, Pre-caution-Adoption Model. The outcome measures varied among the studies, being primarily based upon self-report (dietary consumption, health condition, nutrition knowledge, phys-ical activity and quality of life), and there were also objective measures, based on anthro-pometric measures or various health biomarkers. Generally speaking, the participants had significant changes as a result of the interventions.
