The Growing Well Study

What are the study aims? To understand more about eating habits and age-appropriate food/drink portion sizes of children aged 6 months-5 years old, and how this affects their growth and dental health. Why is this research important? Healthy diets in early years are important for growth and development. However, clear guidance for parents on what and how much children should eat is missing due to lack of up-to-date information. What will the investigators do? Information will be collected at two time points. At baseline, parents/guardians of children aged 6 months-4 years from Leeds, Doncaster and East London will complete questionnaires about their child's sociodemographic information and food intake. They will be asked to record what their child eats for three separate one-day periods using an online system called 'myfood24'. Parents will also attend one in-person session for measuring their child's length/height, weight, and waist circumference. At follow-up one year later, parents/guardians will complete surveys again, with another in-person session to look at growth and assess dental health. What do the investigators expect to achieve and what happens next? They want to understand how growth and dental health are influenced by nutrient intakes, dietary patterns, and portion sizes for key food groups. They will also identify how much of different foods children should be eating, and whether commercial foods and sweet drinks are relevant. They will explore which dietary factors can support healthier children; and how low intakes of key foods or vitamins/minerals in vulnerable groups could be redressed. The study will provide unique information, allowing for development of recommendations for parents and policy-makers on age-appropriate portions, on achieving good nutrition in UK children and within special dietary groups, and on dietary considerations in caring for children's teeth.

n-3 PUFAs, Irisin and Maternal Glucose Metabolism From Pregnancy to Postpartum

This study aims to investigate the associations of maternal nutritional status during pregnancy and postpartum periods with postpartum abnormal glucose metabolism in Guangzhou pregnant women. Additionally, it seeks to explore the relationships between maternal nutritional status (pre- and postnatal) and offspring health outcomes, including physical growth, neurodevelopment, and common childhood diseases.
