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.
