Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 6 months to 4 years and their parents/guardians living in or near Leeds, Doncaster, or East London who can participate in online surveys and in-person measurements.

Probably not a fit

Children whose families cannot complete follow-up or who move away may not contribute to the long-term growth or dental health findings.

What this trial studies

Researchers will collect information from parents in Leeds, Doncaster, and East London at two time points: baseline and one year later. Parents complete questionnaires about sociodemographics and what their child eats for three one-day periods using an online tool, and a clinic visit measures height, weight, and waist. The study aims to define age-appropriate portions and examine how commercial foods, plant-based patterns, and nutrient intakes relate to growth and dental health over 12 months. It will also consider how child and family characteristics, including deprivation and ethnicity, influence dietary patterns and outcomes.

Why it matters

Potential benefit: If successful, the study could provide clearer guidance on portion sizes and dietary patterns for young children to support healthy growth and dental health.

How similar studies have gone: Past work has highlighted gaps in age-appropriate portions and the impact of early diets on growth and dental health, with limited contemporary data in the UK.
