A new study by the Leibniz Institute for Prevention Research and Epidemiology - BIPS has investigated how emotional states influence the eating habits of children and adolescents and which interventions help to change unhealthy eating habits. The research focuses on the role of stress and impulsivity in food choices, particularly in relation to sweet and fatty foods. It has now been published in the International Journal of Behavioral Nutrition and Physical Activity.

"Our study shows that emotional states, especially negative stress, have a significant influence on dietary choices in adolescents," explains Stefanie Do, scientist at BIPS and first author of the publication. "This finding can help to develop effective interventions aimed at changing unhealthy eating patterns."

To investigate the relationship between emotions, impulsivity and the preference for sweet and fatty foods, Do's team analyzed data from the European IDEFICS/I.Family cohort. A large-scale multicenter study in eight European countries (Belgium, Cyprus, Estonia, Germany, Hungary, Italy, Spain, Sweden), which investigated the effects of health-related behaviors on obesity and metabolic disorders in children and adolescents. The survey began in 2007 with 16,230 children aged two to nine years and was continued in further waves until 2021. In the current study, Do's team hypothetically placed all adolescents on a high well-being or low impulsivity score and compared them with the low and high scores to estimate the effects on the propensity to eat sweet and fatty foods.

"The consumption of unhealthy foods, such as sweet or fatty foods, in response to negative emotions is an often unregulated strategy of our body to deal with negative emotions, such as fear, anger, frustration, stress or sadness," explains PD Dr. Antje Hebestreit, head of the Lifestyle-Related Diseases Group at BIPS. "Comparing the effects of well-being and impulsivity on the tendency to eat unhealthy foods, our analyses suggest that impulsivity may have a stronger effect. This underlines the importance of measures that reduce emotion-driven impulsivity. Specifically, exercise, for example, could help."

Adolescents suffering from chronic stress are prone to impulsive behavior and are therefore very susceptible to the increasing availability and advertising of unhealthy foods such as sweets or potato chips. The results of the study are particularly relevant given the strong presence and marketing of unhealthy foods in Europe. Adolescence is a time when young people are learning strategies to cope better with stress. This age group is therefore particularly suitable for appropriate preventative measures. If a person learns unhealthy behaviors during this phase, they usually remain for life. Further research into effective interventions is therefore very important, the team says in its paper.

BIPS - Health research in the service of people

The population is at the heart of our research. As an epidemiological research institute, we see it as our task to identify the causes of health disorders and to develop new concepts for the prevention of diseases. Our research provides the basis for social decisions. It informs the population about health risks and contributes to a healthy living environment.

BIPS is a member of the Leibniz Association, which comprises 97 independent research institutes. The focus of the Leibniz Institutes ranges from the natural, engineering and environmental sciences to economics, spatial and social sciences and the humanities. Leibniz Institutes are dedicated to socially, economically and ecologically relevant issues. Due to their national importance, the federal and state governments jointly fund the institutes of the Leibniz Association. The Leibniz Institutes employ around 20,000 people, including 10,000 scientists. The total budget of the institutes is more than 1.9 billion euros.
