The impact of the COVID-19 pandemic on childhood obesity rates, by Health Board area, in Wales, UK.

BACKGROUND: The aim of this study was to examine the possible impact of the coronavirus pandemic on rates of children living with obesity and severe obesity, by Health Board area in Wales. METHODS: The pre-pandemic data consisted of all children included in the Wales Childhood Measurement Programme (2014/15-2018/19). The 2021/22 Child Measurement Programme data were used as the post-pandemic data set. Body mass index for obesity and severe obesity were calculated as 95th and 99.6th centiles, respectively. RESULTS: Of the 163 277 children measured pre-pandemic (2014/15 to 2018/19), the overall prevalence of children with obesity and severe obesity were 12.1 and 3.2%, respectively. In the post-pandemic year (2021/22), obesity increased to 15.5% and severe obesity increased to 4.8%, with clear deprivation differentials (noting one of the seven Health Boards was unable to submit data post-pandemic). Two Health Boards had significantly higher rates of obesity post-pandemic compared to pre-pandemic. Increased levels of severe obesity were observed in all Health Boards with available data. CONCLUSION: The post-pandemic rise in obesity and severe obesity in young children living in Wales demonstrates a need for more work on the prevention of obesity and severe obesity, targeting the early years and areas of socio-economic disadvantage.

Association between children living with obesity and Mental Health problems: a data analysis of the Welsh Health Survey, UK.

BACKGROUND: Obesity and mental health problems in children are both significant and growing public health issues. There is mixed evidence on the relationship between obesity and mental health in children. This study examines the association between obesity and mental health problems in a nationally representative sample of children using the Welsh Health Survey for Children (n = 11,279 aged 4-15 years). METHODS: The Chi-square test assessed the difference in the proportion of children reporting abnormal mental health scores (strengths and difficulties score ≥ 20) in children living with obesity (≥ 95 centile for age and sex). Then, a multivarible logistic regression was used to assess any association after accounting for confounding variables. RESULTS: There were 1,582 children living with obesity in the study (19.6%). The Chi-square test indicated a significant difference in the proportion of children with abnormal mental health scores in children living with obesity (p = 0.001). This study found a very small but significant positive association between mental health and childhood obesity after accounting for confounding variables, Odds Ratio 1.02 (95%CI: 1.01 to 1.02, p = 0.001). However, socio-economic status was more of a driver. CONCLUSION: The findings of this study show a very small but significant association between childhood obesity and mental health problems. The multivariable logistic regression indicates that the focus must remain on reducing health inequalities as this is a more important driver of child health and well-being. However, as a precautionary measure it may be worth considering if children living with obesity who present for weight-management services may benefit from a review of their mental health status to identify if further support is needed, if capacity allows, and this can be done in a supportive way.

Living with obesity is related to peer problems in children: A national cross-sectional study.

AIM: To assess the association between obesity and problems in peer relations in children (4-15 years) in a large (n = 11 279), nationally representative data set. METHODS: The chi-square test was used to compare differences in numbers of children with and without obesity and with and without abnormal peer problem scores. Then multivariable logistic regression was used to determine any association between obesity and peer problems after accounting for deprivation and life-style factors. RESULTS: The results of the chi-square test were statistically significant (P < 0.05) for all groups except older girls. The multivariable logistic regression identified a small but significant association between children living with obesity and abnormal peer problems, odds ratio (OR) 1.06 (95% confidence interval, CI: 1.04-1.08, P = 0.001). When explored by subsets of children using sex and age, this association was strongest for girls aged 4-10 years, OR 1.12 (95% CI: 1.07-1.16, P = 0.001). CONCLUSION: This is the first nationally representative study of children to identify this association in younger children. Whilst further research is needed to corroborate this finding, as a precautionary measure solutions to improve peer relationships and reduce stigma for school-aged children living with obesity are indicated.

A cross-sectional study using the Childhood Measurement Programme for Wales to examine population-level risk factors associated with childhood obesity.

OBJECTIVE: The aim of this cross-sectional study was to examine the association between childhood obesity and modifiable population-level risk factors, after accounting for deprivation. DESIGN: A review of the literature identified population-level risk factors including a healthy childcare setting, the local food environment, accessible open space, community safety and crime. Data for these risk factors were then identified and matched by each of the twenty-two local government areas in Wales to each child that had data on height and weight in the Wales Childhood Measurement Programme (CMP) (2012-2017). Multivariable logistic regression was used to identify associations with childhood obesity. SETTING: The current study was undertaken in Wales, UK, where approximately one in eight 4-5-year-olds are classified as obese. PARTICIPANTS: All participants were children aged 4 or 5 years who attend school, measured as part of the CMP, between 2012 and 2017 (n 129 893, mean age 5·0 (sd 0·4) years). RESULTS: After adjusting for deprivation, small but statistically significant associations were found between childhood obesity and percentage of land available as accessible open space OR 0·981 (95 % CI: 0·973, 0·989) P < 0·001) and density of fast food outlets OR 1·002 (95 % CI 1·001, 1·004, P = 0·001). No other population-level risk factors were associated with childhood obesity. CONCLUSIONS: The current study indicates that, even after accounting for deprivation, risk factors such as the density of fast food outlets and access to green space should be considered when tackling childhood obesity as a public health issue.

Prevalence of severe childhood obesity in Wales UK.

BACKGROUND: In Wales, approximately one in eight children is obese (aged 4-5 years). The aim of this prevalence study was to examine the trends in severe childhood obesity and investigate any relationship with socioeconomic deprivation. METHODS: Data for all children included as part of the Wales Childhood Measurement Programme (2013/14-2017/18) were utilized. Data on the number who had a body mass index above the 99.6th centile indicating severe obesity were calculated over time by sex and in relation to deprivation. RESULTS: Of the 162 208 children measured between 2013/14 and 2017/18 (mean age 5.06 years, standard deviation 0.35 years), the overall prevalence of severe obesity was 3.1% (95% confidence interval [CI] 3.0-3.2%). This varies from 1.9% (95% CI 1.7-2.1%) in the least deprived areas to 3.9% (95% CI 3.7-4.0%) in the most deprived areas. Boys have higher prevalence of severe obesity than girls: 3.6% (95% CI 3.4-3.9%) of boys (n = 598) and 3.0% (95% CI 2.7-3.2%) of girls (n = 467) were categorized as severely obese in reception year in Wales in 2017/18. Prevalence has increased over time but this is not statistically significant. CONCLUSION: This study found significantly higher levels of severe obesity in areas of socioeconomic deprivation. Levels of severe obesity were significantly higher in boys than in girls.

Learning across the UK: a review of public health systems and policy approaches to early child development since political devolution.

BACKGROUND: Giving children the best start in life is critical for their future health and wellbeing. Political devolution in the UK provides a natural experiment to explore how public health systems contribute to children's early developmental outcomes across four countries. METHOD: A systematic literature review and input from a stakeholder group was used to develop a public health systems framework. This framework then informed analysis of public health policy approaches to early child development. RESULTS: A total of 118 studies met the inclusion criteria. All national policies championed a 'prevention approach' to early child development. Political factors shaped divergence, with variation in national conceptualizations of child development ('preparing for life' versus 'preparing for school') and pre-school provision ('universal entitlement' or 'earned benefit'). Poverty and resourcing were identified as key system factors that influenced outcomes. Scotland and Wales have enacted distinctive legislation focusing on wider determinants. However, this is limited by the extent of devolved powers. CONCLUSION: The systems framework clarifies policy complexity relating to early child development. The divergence of child development policies in the four countries and, particularly, the explicit recognition in Scottish and Welsh policy of wider determinants, creates scope for this topic to be a tracer area to compare UK public health systems longer term.

Risk factors for childhood obesity: a data analysis of the Welsh Health Survey.

Background The prevalence of childhood obesity in Wales is 12%. It has been estimated that obesity will cost the NHS £10 billion a year by 2050 ( Government Office for Science 2007 ). Aim To determine important risk factors associated with childhood obesity from the data in the Welsh Health Survey 2008 to 2012. Method The analysis used survey data from 11,279 children aged 4-15 years. The lifestyle variables considered as potential risk factors for obesity included: intake of sugar-sweetened drinks; unhealthy food consumption; physical activity; and currently-treated illnesses. The sociodemographic and socioeconomic factors included: sex; age; Welsh Index of Multiple Deprivation quintile; National Statistics Socio-economic Classification; and housing tenure. Results A total of 1,582 (20%) children were obese. A significant association was found between obesity and having one illness - odds ratio (OR) 1.20 (95% confidence interval (CI): 1.05 to 1.38, P=0.008) and having two or more illnesses - OR 1.50 (95% CI: 1.22 to 1.85, P<0.001), and not meeting the physical activity recommendation - OR 1.33 (95% CI: 1.17 to 1.52, P<0.001). Conclusion Every child should meet the physical activity recommendation and those with an illness should receive a care plan to prevent or manage obesity, although this is difficult in the time available for children in clinics and consultations.

"I won't call it rationing...": an ethnographic study of healthcare disinvestment in theory and practice.

Healthcare decision-makers have always faced the challenge of allocating finite resources, but the global economic downturn places extra pressure on health systems to meet rising demands. The National Institute for Health and Care Excellence (NICE) and UK government have therefore called on commissioners to consider opportunities for 'disinvestment'- the cessation or restriction of health-care practices, and subsequent shift of resources to higher value care. However, there are no clear guidelines on how to approach disinvestment, and little is known about how this is tackled in practice. This paper presents results from a study that used ethnographic methods to investigate how disinvestment is understood and enacted. Eight routine local-level commissioning meetings where resource allocation decisions were discussed were observed over one year in two demographically contrasting regions of England. 28 interviews accompanied observations, conducted with purposefully-sampled professionals who were involved in, or potentially impacted by, disinvestments. Analysis of interviews/meeting recordings was undertaken using constant comparison methods, complemented by observational field notes. We found variation in informants' reported definitions of disinvestment, and an absence of disinvestment decision-making in observed meetings. Observations and interviews showed evidence of practical and ideological barriers to disinvestment, including an absence of tools and capacity, difficulties in collaboration and communication, a reluctance to engage in explicit rationing, and a perceived lack of central/political support. These findings support the need for the development of methods to encourage and guide disinvestment, including a clear definition of what 'disinvestment' entails. Crucially, disinvestment needs to be a collaborative effort, involving health-care providers and commissioners in decision-making processes.
