Beverage consumption patterns in elementary school aged children across a two-year period

Area of Science:

• Pediatric Nutrition
• Obesity Research
• Dietary Habits

Background:

• Childhood obesity is a growing public health concern.
• Understanding beverage consumption patterns is crucial for weight management in children.
• Previous studies have shown mixed results on beverage intake and Body Mass Index (BMI).

Purpose of the Study:

• To analyze changes in beverage consumption over two years in children.
• To investigate the association between specific beverages and BMI Z-score changes.
• To identify beverage consumption trends in normal weight versus overweight children.

Main Methods:

• Re-analysis of existing data from 164 children over two years.
• Beverage intake (milk, juice, diet/sugar-sweetened soda) assessed via 24-hour recall.
• Height and weight measured to calculate BMI Z-scores at baseline and year 2.

Main Results:

• Significant decrease in milk and increase in diet soda consumption observed over two years.
• Overweight children showed a significant increase in diet soda intake.
• Diet soda consumption at year 2, along with baseline BMI Z-score, predicted 83.1% of year 2 BMI Z-score variance.

Conclusions:

• Beverage consumption patterns shifted significantly in this cohort.
• Diet soda consumption emerged as the sole beverage type associated with increased BMI Z-score.
• Increased diet soda intake was more pronounced in overweight and weight-gaining children, highlighting a need for further longitudinal research.
