Objective To determine if a school based educational programme aimed at reducing consumption of carbonated drinks can prevent excessive weight gain in children. Design Cluster randomised controlled trial. Setting Six primary schools in southwest England. Participants 644 children aged 7-11 years. Intervention Focused educational programme on nutrition over one school year. Main outcome measures Drink consumption and number of overweight and obese children. Results Consumption of carbonated drinks over three days decreased by 0.6 glasses (average glass size 250 ml) in the intervention group but increased by 0.2 glasses in the control group (mean difference 0.7, 95% confidence interval 0.1 to 1.3). At 12 months the percentage of overweight and obese children increased in the control group by 7.5%, compared with a decrease in the intervention group of 0.2% (mean difference 7.7%, 2.2% to 13.1%). Conclusion A targeted, school based education programme produced a modest reduction in the number of carbonated drinks consumed, which was associated with a reduction in the number of overweight and obese children.

Objective To assess the long term effects of an obesity prevention programme in schools. Design Longitudinal results after a cluster randomised controlled trial. Setting Schools in southwest England. Participants Of the original sample of 644 children aged 7-11, 511 children were tracked and measurements were obtained from 434 children three years after baseline. Intervention The intervention was conducted over one school year, with four sessions of focused education promoting a healthy diet and discouraging the consumption of carbonated drinks. Main outcome measures Anthropometric measures of height, weight, and waist circumference. Body mass index (BMI) converted to z scores (SD scores) and to centile values with growth reference curves. Waist circumference was also converted to z scores (SD scores). Results At three years after baseline the age and sex specific BMI z scores (SD scores) had increased in the control group by 0.10 (SD 0.53) but decreased in the intervention group by −0.01 (SD 0.58), with a mean difference of 0.10 (95% confidence interval −0.00 to 0.21, P=0.06). The prevalence of overweight increased in both the intervention and control group at three years and the significant difference between the groups seen at 12 months was no longer evident. The BMI increased in the control group by 2.14 (SD 1.64) and the intervention group by 1.88 (SD 1.71), with mean difference of 0.26 (−0.07 to 0.58, P= 0.12). The waist circumference increased in both groups after three years with a mean difference of 0.09 (−0.06 to 0.26, P=0.25). Conclusions These longitudinal results show that after a simple year long intervention the difference in prevalence of overweight in children seen at 12 months was not sustained at three years.

Aims: The increasing prevalence of childhood obesity is a global problem. There are a variety of environmental factors that may be contributing to this increase. One such factor may be the increased consumption of soft drinks. Objective: This review will describe some of the latest research that has examined the association between obesity and the consumption of soft drinks. Results: The association between the consumption of sugar-sweetened drinks and childhood obesity has been established in three separate American studies. It has been found that children who consume these drinks have a higher energy intake and are more likely to become overweight. In adult women, the consumption of sugar-sweetened soft drinks has been associated with an increased risk of developing diabetes. In the United Kingdom, a school-based initiative focusing on reducing the consumption of these drinks has also been effective in preventing a further increase in obesity. Conclusions: There is an association between obesity and consumption of soft drinks. Initiatives focusing on reducing the consumption of these drinks may help to prevent a further increase in childhood obesity.

Aim: The aim was to explore personal experiences and to determine the impact of impaired sleep on well-being and diabetes-related activities/decision making among a cohort of people living with T1D. Method: Adults with T1D over the age of 18 and parents/carers of children with T1D were invited to complete an online questionnaire about their quality and quantity of sleep. Questions included impact of sleep on diabetes-related decision making, effective calculation of bolus doses, important aspects of psychosocial functioning, and frequency of waking. Diasend download data were used to objectively determine frequency of nocturnal blood glucose testing in children. Results: A total of 258 parent/carer participants (n = 221 female, 85.6%) and 192 adults with T1D (n = 145, 75.5% female, age range 19 to 89 years) took part. In all, 239 parents/carers and 160 adults believed waking in the night has an impact on their usual daily functioning. Of these, 236 parents/carers and 151 (64%) adults reported the impact as negative. Chronic sleep interruption was associated with detrimental impact on mood, work, family relationships, ability to exercise regularly, ability to eat healthily, and happiness. Conclusion: Chronic sleep interruption is highly prevalent in adults with T1D and parents/carers of children with T1D with negative effects on daily functioning and well-being. Appropriate interventions are required to alleviate this burden of T1D, address modifiable risk factors for nocturnal hypoglycemia, and reduce the (perceived) need for nocturnal waking.

Worldwide initiatives currently aim to reduce free sugar intakes, but success will depend on consumer attitudes towards sugar and the alternatives. This work aimed to explore attitudes towards sugar, sweeteners and sweet-tasting foods, towards consumption and related policies, in a sample of the general public of the UK. Focus groups and interviews were conducted with 34 adults (7 males, ages: 18–65 years). Thematic analysis identified six themes: ‘Value’ (e.g., pleasure, emotions), ‘Angle’ (e.g., disinterest), ‘Personal Relevance’ (to be concerned and/or change one’s own behavior), ‘Personal Responsibility’ (one has an active relationship with these food items), ‘Understanding’ (the acquisition, comprehension and application of information) and ‘It’s Not Up to Me’ (a passive approach, because intake is subjected to other factors). Both positive and negative attitudes towards sugar, sweeteners and sweet-tasting foods were expressed in all themes. Participants also reported varied engagement with and motivations towards all food items, with implications for intakes. Suggested challenges and potential strategies for reducing free sugar intakes highlighted the need for differing approaches. Future work should assess associations between attitudes and intakes. For greatest population benefit, evidence of the dominant attitudes in those in greatest need of reduced free sugar intakes would be of value.

Diabulimia has become a common term used to describe a condition when a person with type 1 diabetes has an eating disorder. The individual may omit or restrict their insulin dose to lose/control weight. Evidence suggests that as many as 20% of women with type 1 diabetes may have this condition. The serious acute and long-term complications of hyperglycaemia are well documented. Detection of this condition is challenging and health professionals need to be vigilant in assessing reasons for variable glycaemic control and weight changes. Management requires a collaborative response from the specialist diabetes team in conjunction with the mental health team. Nurses must ensure that they are aware that the condition may be possible in all patients with type 1 diabetes but especially younger female patients. These patients require timely intervention to prevent any severe acute or long-term complications.
