Environmental Determinants of Pediatric Obesity: An Epidemiological Review

Area of Science:

• Public Health
• Environmental Health
• Pediatrics

Background:

• Pediatric obesity is a rapidly growing global public health concern.
• While genetics play a role, recent increases in prevalence are driven by environmental shifts.
• Understanding these environmental factors is crucial for effective intervention.

Purpose of the Study:

• To review the major environmental determinants of childhood obesity.
• To identify how various environmental factors influence weight-related behaviors.
• To highlight research gaps and intervention opportunities.

Main Methods:

• This is a narrative review summarizing existing evidence.
• Key environmental contributors were identified and analyzed.
• The review synthesizes data on factors like food, physical activity, and socioeconomic context.

Main Results:

• Environmental contributors include food, physical activity, built, socioeconomic, family, digital, and chemical obesogen environments, alongside policy drivers.
• These factors impact dietary habits, activity patterns, sleep, and stress levels.
• Disadvantaged communities often exhibit a clustering of these factors, increasing obesity risk for specific populations.

Conclusions:

• Environmental factors are the primary drivers of the recent surge in childhood obesity.
• Multisectoral interventions are needed to address the complex environmental influences.
• Targeting environmental determinants offers opportunities to curb the rising prevalence of pediatric obesity.
