Exploring overweight and obesity in pre-school children using routinely collected data: a case study of Halton,...

Area of Science:

• Pediatric Health
• Public Health
• Growth Monitoring

Background:

• Childhood overweight and obesity are significant public health concerns.
• Evidence suggests early life factors influence later weight status.
• Understanding infant weight patterns is crucial for early intervention.

Purpose of the Study:

• To investigate weight patterns in children from birth to 40 months in Halton, UK.
• To compare Halton infants' growth trajectories with UK-90 reference data.
• To identify trends and gender differences in infant overweight and obesity.

Main Methods:

• Analysis of 16,381 births between 1994 and 2006 in Halton.
• Comparison of infant anthropometric data (heights and weights) with UK-90 reference population.
• Calculation of age-sex adjusted SD scores and analysis of centile data using Poisson regression.

Main Results:

• Halton infants showed consistently higher proportions above the 85th and 95th centiles at birth, 8 months, and 40 months compared to reference data.
• While initial birth centiles remained stable, proportions above the 85th and 95th centiles increased significantly in later cohorts for other time points.
• Cohort trends indicated a rise in infant overweight and obesity over successive birth years.

Conclusions:

• The study provides evidence that the origins of overweight and obesity can be traced to early infancy.
• Identified specific patterns of infant overweight and obesity in the Halton cohort.
• Highlights the need for early life interventions to address childhood obesity.
