The first 1, ,000 days : a window of opportunity to reduce social inequalities in health. Example of the ECAIL study, a complex public health intervention

Abstract

There are major social inequalities in health in France, particularly for chronic diseases linked to diet, physical activity and sedentary behavior. These behaviors, involved in energy balance, are socially differentiated from an early age. One of the consequences of this is the higher prevalence of overweight in more disadvantaged environments, from the age of two onwards. Growing knowledge of the early origins of health reinforces the case for targeting the so-called 1 000 first days window to promote health-promoting behaviors. In a context of growing food insecurity and precariousness, it is essential to develop and evaluate innovative public health programs, combining nutritional support with easier access to good-quality food. The ECAIL intervention study aims to test the effectiveness of such a program on the diet, lifestyles and growth of young children in socially vulnerable situations.

Sandrine Lioret is a researcher in epidemiology / public health, and works in an Inserm team dedicated to research into the early origins of health. Her research activities focus on vulnerabilities and social inequalities in health, with an emphasis on early growth and childhood overweight. It seeks to understand how behaviors related to energy balance, i.e. diet, sedentary behavior and physical activity, are involved in the expression of such social inequalities in health, with a dual approach, observational and interventional.
