Early determinants of obesity

Area of Science:

• Pediatrics
• Public Health
• Developmental Biology

Background:

• High rates of childhood overweight and obesity necessitate early prevention strategies.
• Rapid infant weight gain, starting from birth, is a critical predictor of later obesity.
• Early puberty and menarche are linked to infant weight gain and predict adult chronic diseases.

Purpose of the Study:

• To highlight the importance of early life interventions for preventing childhood overweight.
• To underscore the long-term health consequences of rapid infant weight gain.
• To inform the development of effective obesity prevention strategies from infancy.

Main Methods:

• Review of historical studies, prospective birth cohorts, and genetic studies.
• Analysis of factors influencing rapid infant weight gain.
• Examination of the relationship between infant adiposity and adolescent/adult health outcomes.

Main Results:

• The trajectory to adult obesity is established in the first months of life.
• Early puberty and menarche are consequences of rapid infant weight gain and predict future chronic disease.
• Understanding determinants of infant weight gain is crucial for developing prevention strategies.

Conclusions:

• Obesity prevention strategies must commence in early life, targeting rapid infant weight gain.
• Further research into infant adiposity regulation and modifiability during adolescence is needed.
• Early life interventions can mitigate risks for obesity, diabetes, hypertension, and cardiovascular disease later in life.
