Diet quality in childhood: the Generation R Study

Area of Science:

• Pediatric Nutrition
• Public Health Nutrition
• Childhood Diet Quality Assessment

Background:

• Diet quality in childhood is crucial for long-term health outcomes.
• Understanding sociodemographic and lifestyle correlates can inform targeted interventions.
• Tracking of diet quality from early to mid-childhood is not well-established.

Purpose of the Study:

• To evaluate the diet quality of 8-year-old children in the Netherlands.
• To identify sociodemographic and lifestyle factors associated with children's diet quality.
• To examine the tracking of diet quality from early childhood (age 1) to mid-childhood (age 8).

Main Methods:

• A population-based cohort of 4733 children aged 8 years was studied.
• Dietary intake was assessed using a validated food-frequency questionnaire.
• A 10-component food-based diet quality score was developed and validated against dietary guidelines.

Main Results:

• The mean diet quality score was 4.5 out of 10, indicating suboptimal intake of legumes, nuts, and healthy oils, and excessive intake of sugar-sweetened beverages and processed meats.
• Higher maternal education, higher household income, non-smoking mothers, and less screen time were significantly associated with better child diet quality.
• Diet quality showed weak tracking from age 1 to age 8 (Pearson's r = 0.19).

Conclusions:

• The overall diet quality of 8-year-old children in the Netherlands does not meet recommended dietary guidelines.
• Children with higher screen time, from lower socioeconomic backgrounds, or with mothers who smoke have poorer diet quality.
• Interventions should consider these sociodemographic and lifestyle factors to improve children's nutritional status.
