Intergenerational Influences on Childhood Obesity and Nutrition
Summary
The tendency for excess weight and dietary patterns to span generations reflects a complex interplay of genetic predisposition, prenatal environmental exposures and shared family behaviours. Parental body mass and metabolic status prior to and during pregnancy can programme offspring adiposity through intrauterine influences on appetite regulation and energy metabolism. Post-delivery, the household food environment, feeding practices and cultural norms further reinforce trajectories of weight gain or healthy growth. Grandparents, as secondary caregivers, often shape snack and meal provision in ways that can either support or undermine parental efforts to promote balanced diets. Socioeconomic factors, education and intergenerational beliefs about nutrition converge to influence children’s eating habits and physical activity levels. Recognising these pathways underpins multi-generational strategies for preventing childhood obesity and improving lifelong health outcomes.

Intergenerational Influences on Childhood Obesity and Nutrition publication trend
The graph below shows the total number of articles in intergenerational influences on childhood obesity and nutrition across all publications each year (not limited to Nature Index journals).
Technical terms
Body mass index (BMI): A numerical measure of weight relative to height squared, used to classify underweight, healthy weight, overweight and obesity.
Adiposity: The accumulation of fat tissue in the body, contributing to overall body composition and metabolic health.
Intrauterine programming: Developmental processes in the womb by which maternal nutrition and metabolism influence the long-term physiological and metabolic outcomes of the offspring.
Trace elements: Minerals present in minute quantities in the body, such as copper and zinc, which can affect metabolic and inflammatory pathways in obesity.
Grandparental caregiving: The role of grandparents in providing dietary and supervisory care, which can shape grandchildren’s eating behaviours and nutritional outcomes.
