Obesity is becoming an increasing problem in children. This is thought to be due to a range of causes which include diets that are high in sugars and other unhealthy foods and drinks, larger portion sizes and children taking less physical activity. Many children attend nurseries and pre-schools and these are an important influence on the children’s eating behaviours and physical activity levels. Birmingham City Council and Birmingham Community Health Care NHS Trust have developed a training programme for staff who work in nurseries. This teaches them about how they can make the nursery a healthier environment. The CLAHRC team is doing a study to see what effect this training has on the activities provided by the nurseries. We have asked all nursery staff attending the training to complete a questionnaire about the food and drinks offered, opportunities for active play, how the staff act as role models to the children for healthy behaviours. This questionnaire will be repeated one year after the training programme was delivered.
