Approximately 1 in 5 children in the UK are overweight or obese by the time they start school. Childhood obesity has harmful effects on physical and mental health. These harmful effects continue into adulthood. Preventing this happening is very important. Establishing healthy eating in pregnancy and early childhood is important for healthy growth and development as well as preventing obesity. Poor eating patterns developed early can continue, and have been shown to relate to increased risk of obesity, heart disease, cancer and diabetes in adulthood.
What we are doing about it
Using questionnaires we have looked at the diet and eating habits of pregnant women, and parent feeding styles, for example breast or bottle feeding and weaning and learnt more about what infants eat at different ages. We have found that:
- Infants are more likely to be overweight/obese at 3 years if their mums are obese and also if their mums smoke during pregnancy
- White British mums in Bradford were more likely to smoke during pregnancy compared to mums of South Asian origin
- White British mums breast fed their infants for less time and weaned earlier compared to mums of South Asian origin
- South Asian mums were less physically active and had higher rates of gestational diabetes (the sort of diabetes that develops in pregnancy)
- Pakistani families had more fresh fruit and vegetables in their homes than homes of White families – but also more sugary drinks
- Obese mums were most likely to use positive comments during feeding, but were also less likely to set limits or boundaries on what their children ate.
- Diet during infancy is related to ethnicity – Pakistani infants had more sugary drinks, commercial sweet baby meals, fruits and vegetables. White British infants ate more processed meats
We have used this information to:
- Develop a programme called ‘HAPPY’ to help prevent the children of obese mums from developing childhood obesity. This programme has been developed in a way that will work with Pakistani and White British mums. We have added what we have learnt in BiB to other evidence gathered in studies across the world to improve diet and eating behaviours and reduce obesity.
Our future plans
We would like to spread the HAPPY programme across the country to benefit everyone. We will continue to assess what the children are eating as they grow and how this impacts on their health and well-being.
