A systematic evaluation of physical activity and diet policies in Scotland: results from the 2021 Active Healthy Kids Report Card.

BACKGROUND: Policymaking regarding physical activity (PA) and diet plays an important role in childhood health promotion. This study provides a detailed examination of Scottish government and policy for child and adolescent PA and diet and discusses strengths and areas for improvement. METHODS: Scottish policy documents (n = 18 [PA]; n = 10 [diet])-published in 2011-20-were reviewed for grading using an adapted version of the Health-Enhancing Physical Activity Policy Audit Tool Version 2. RESULTS: There is clear evidence of leadership and commitment to improving PA and diet and tackling obesity in children and adolescents. The allocation of funds and resources for policy implementation has increased substantially over the past decade. Progress through early key stages of public policymaking-policy agenda and formation-has improved. However, there is limited information on later key stages, including policy monitoring and evaluation. CONCLUSIONS: Childhood PA and diet are a clear priority in Scotland, and PA and diet policies clearly support the desire to achieve other goals, including reducing inequalities and increasing active travel in Scotland. Nonetheless, future policies should be further strengthened through clear(er) plans of implementation, and monitoring and evaluation to support their societal impact.

Results from Scotland's 2021 report card on physical activity and health for children and youth: Grades, secular trends, and socio-economic inequalities.

Background: The 2021 Active Healthy Kids Scotland Report Card aimed to identify secular trends and socio-economic inequalities, and to assess the physical activity and health of children and youth prior to COVID-19. Methods: An expert panel searched for data published in 2018-2020. Grades were assigned to nationally representative data using the Active Healthy Kids Global Alliance methodology. Results: The expert panel, following national consultation, awarded the following grades: Community/Environment B-, Organized Sport and Physical Activity B-, Government/Policy C-/C+, Active Transportation C-, Family/Peers D-, Recreational Screen Time F. Five indicators were graded inconclusive (INC): Overall Physical Activity; Active Play; Physical Fitness; Diet; Obesity. Grades have remained stable or declined, and surveillance has reduced, increasing the number of INC grades. There were marked socio-economic inequalities for eight indicators (Recreational Screen Time; Overall Physical Activity; Organized Sport & Physical Activity; Active Transportation; Diet; Obesity; Family/Peers; Community/Environment). Conclusions: Despite a decade of favorable policy, physical activity and health of children and youth has not improved, and marked socio-economic inequalities continue to persist in Scotland. There is a clear need for greater monitoring of physical activity and health, and improved policy implementation and evaluation, particularly as many indicators and related inequalities may have worsened following the COVID-19 pandemic.

Food-Level Analysis to Identify Dietary Choices With the Highest Nutritional Quality and Lowest Greenhouse Gas Emissions and Price.

Introduction: Food systems are challenged to provide healthy, sustainable and affordable foods. From a consumer perspective, identifying healthy, sustainable and affordable choices based on individual food products rather than diets could promote better shopping choices. Objective: To identify foods and drinks with the highest nutritional quality and lowest greenhouse gas emissions (GHGE) and price. We also assessed how a combination of these indicators (e.g., nutritional quality, GHGE and price) for food categories aligned with current United Kingdom dietary recommendations. Materials and Methods: We performed a secondary analysis of the National Diet and Nutrition Survey (NDNS) nutrient databank year 11 (2018/2019). Spearman correlation coefficients were used to assess the strength of relationships between nutritional quality, environmental impact and/or prices per 100 kcal. In addition, we developed an optimized nutritional quality, GHGE and price score for each food or drink item based on the overall medians for each of these indicators. Results: Median nutritional value was highest for fruit and vegetables, whilst median GHGE and price was lower for starchy carbohydrates, fats and items of which consumption should be limited. The relative proportions of foods considered the most nutritious and with a low GHGE and price in each of the food categories, on a per 100 kcal basis, were comparable to the proportions in the Eatwell Guide, except for the proportion of fruits and vegetables being smaller and the proportion of potatoes, bread, rice, pasta, and other starchy carbohydrates being larger in our analysis. Conclusion: Public health efforts should consider the impact of dietary choices not only in terms of nutritional quality but also in terms of environmental and economic impact. Our food-based analysis shows a large variation in nutritional quality, GHGE and price within and across food categories, which provides consumers with opportunities for "food swaps" that are more nutritious and have lower GHGE and price.

Nutritional Quality, Environmental Impact and Cost of Ultra-Processed Foods: A UK Food-Based Analysis.

Food-based analyses of the healthiness, environmental sustainability and affordability of processed and ultra-processed foods are lacking. This paper aimed to determine how ultra-processed and processed foods compare to fresh and minimally processed foods in relation to nutritional quality, greenhouse gas emissions and cost on the food and food group level. Data from the National Diet and Nutrition Survey nutrient databank year 11 (2018/2019) were used for this analysis. Median and bootstrapped medians of nutritional quality (NRF8.3 index), greenhouse gas emissions (gCO2-equivalents) and cost (in GBP) were compared across processing categories. An optimal score based on the medians was created to identify the most nutritional, sustainable, and affordable options across processing categories. On a per 100 kcal basis, ultra-processed and processed foods had a lower nutritional quality, lower greenhouse gas emissions, and were cheaper than minimally processed foods, regardless of their total fat, salt and/or sugar content. The most nutritious, environmentally friendly, and affordable foods were generally lower in total fat, salt, and sugar, irrespective of processing level. The high variability in greenhouse gas emissions and cost across food groups and processing levels offer opportunities for food swaps representing the healthiest, greenest, and most affordable options.

Pilot randomised controlled trial of Weight Watchers® referral with or without dietitian-led group support for weight loss in women treated for breast cancer: the BRIGHT (BReast cancer weIGHT loss) trial.

BACKGROUND: Being overweight or obese following breast cancer diagnosis can increase cancer recurrence and mortality, so effective interventions for weight loss in this group could enhance survival. A pilot randomised controlled trial was conducted to assess whether a weight loss programme comprising generic Weight Watchers® referral offered to women treated for breast cancer with or without additional breast cancer-tailored dietetic support is feasible and shows promise for improving weight and quality of life (QoL). METHODS: Participants were randomly allocated to 3 groups: Weight Watchers® referral (for 12 sessions of meetings and digital tools) plus 5 breast cancer-tailored dietitian-led group support sessions (WW Plus: n = 14), Weight Watchers® referral only (WW: n = 16) or control (Weight Watchers® referral after 3 months, n = 15). Feasibility was assessed based on retention rate, recruitment and randomisation process, meeting attendance, suitability of the setting and outcome measurement tools, unintended consequences, cost and observations of the dietetic sessions. Outcomes were measured at 0, 3 ('trial exit') and 12 months post intervention. RESULTS: The response rate to the invitation was 43% (140/327) of whom 58 were eligible and 45 (median age 61.0 years; body mass index 30.2 kg/m2) were randomised. Data from 38 (84%) and 30 (67%) participants were available at trial exit and 12 months respectively. Feasibility issues included slow recruitment process, lack of blinding throughout, weighing scales not measuring > 150 kg, lack of clear instructions for completing QoL questionnaire and workload and time pressures in delivering dietetic sessions. Participants had good attendance rate at group meetings and no serious unintended consequences were reported. WW Plus was most expensive to run. Mean (95% CI) weight change at trial exit was - 3.67 kg (- 5.67, - 2.07) in WW Plus, - 6.03 kg (- 7.61, - 4.44) in WW group and + 0.19 kg (- 1.45, + 1.83) in control group. About 40% of the WW Plus, 64% of the WW group and 56% of the control group lost ≥ 5% of their baseline weight by 12 months. All groups showed promise for improving QoL at trial exit but only the WW group maintained significant improvements from baseline at 12 months. CONCLUSIONS: The trial procedures were feasible, with some modifications. This pilot trial indicates the benefits of providing free WW vouchers for weight loss maintenance and improving QoL but provided no evidence that including additional dietetic support would add any extra value. Further research with WW with long-term follow-up should be undertaken to assess weight loss sustainability and benefit on health outcomes in this patient group. TRIAL REGISTRATION: ISRCTN-29623418.

Estimating plate-based model food proportions in adults living in Scotland using short dietary assessment questionnaires.

AIM: To determine whether a food frequency questionnaire (FFQ) and a short dietary assessment tool can be used to accurately estimate the Eatwell Guide proportions (a plate-based food model) of diets of adults living in Scotland. METHODS: The cross-sectional study was conducted as a follow up of the 2010 Scottish Health Survey (participants aged 18-65 years old). Proportions of the Eatwell Guide food groups (starchy carbohydrates, fruits and vegetables (F&V), dairy and alternatives, protein foods and oils and spreads) were calculated from the Scottish Health Survey Eating Habits Module (SHeS EHM), Scottish Collaborative Group FFQ (SCG FFQ) and a seven-day estimated food diary (reference method), and compared using the Aitchison method and Wilcoxon Signed-Rank Test. Bland-Altman analyses assessed mean difference and 95% limits of agreement between the methods for each food group. RESULTS: Ninety-six adults were included (mean (SD) age = 51.4 (11.1) years; body mass index = 27.1 (4.9) kg/m2 ; 58% female). The SCG FFQ scored a lower median Aitchison distance (1.47) than the SHeS EHM (1.99) (P < 0.001), showing greater agreement with the reference method (P < 0.001). Bland-Altman plots also showed better agreement for the SCG FFQ than the SHeS EHM. Poorest agreement was for starchy carbohydrates (both methods), protein foods (SHeS EHM) and dairy (SCG FFQ). CONCLUSIONS: The SCG FFQ could be used to estimate Eatwell Guide proportions and monitor compliance to the Eatwell Guide recommendations and could be improved with small changes. The SHeS EHM is less suitable, but additional questions on dairy foods, and oils and spreads would improve its ability to estimate the Eatwell Guide proportions.

How important are the influencing factors to the decision on whether to provide seafood in infant and young child feeding?

Seafood is recommended as part of a healthy, balanced introductory diet however, consumption rates are low in young children. Research has previously investigated the influences to seafood consumption in consumers and non-consumers however the importance of these factors in mothers' decisions on whether to provide seafood for their child during the early years is unknown. This study aimed to measure the importance of factors that influence mothers' decisions on providing seafood for their child during infant and young child feeding (six months to four years). A mixed method Q methodology and cognitive interview approach was used with 32 mothers in Scotland. Despite a large consensus of opinion between mothers (n = 20) on the importance of factors on their decision-making, two viewpoints emerged highlighting an importance placed on food attributes and the infant, and convenience and family-centred. This study is the first to quantify the influences on the decision to provide seafood during early years' feeding and could be used to inform and tailor seafood-based dietary promotions and interventions for parents.

Mediterranean-type diet and brain structural change from 73 to 76 years in a Scottish cohort.

OBJECTIVE: To assess the association between Mediterranean-type diet (MeDi) and change in brain MRI volumetric measures and mean cortical thickness across a 3-year period in older age (73-76 years). METHODS: We focused on 2 longitudinal brain volumes (total and gray matter; n = 401 and 398, respectively) plus a longitudinal measurement of cortical thickness (n = 323), for which the previous cross-sectional evidence of an association with the MeDi was strongest. Adherence to the MeDi was calculated from data gathered from a food frequency questionnaire at age 70, 3 years prior to the baseline imaging data collection. RESULTS: In regression models adjusting for relevant demographic and physical health indicators, we found that lower adherence to the MeDi was associated with greater 3-year reduction in total brain volume (explaining 0.5% of variance, p < 0.05). This effect was half the size of the largest covariate effect (i.e., age). Cross-sectional associations between MeDi and baseline MRI measures in 562 participants were not significant. Targeted analyses of meat and fish consumption did not replicate previous associations with total brain volume or total gray matter volume. CONCLUSIONS: Lower adherence to the MeDi in an older Scottish cohort is predictive of total brain atrophy over a 3-year interval. Fish and meat consumption does not drive this change, suggesting that other components of the MeDi or, possibly, all of its components in combination are responsible for the association.

Factors influencing mothers' decisions on whether to provide seafood during early years' feeding: A qualitative study.

The first year of a child's life is a key period of transition from an exclusive milk diet to solid foods to meet growing nutritional demands. An increased requirement for nutrients includes the introduction of protein-rich solid foods, such as seafood, which additionally provides valuable omega-3 fatty acids. However, consumption of seafood is low in the British child population. The aim of this study was to identify maternal perceptions of the factors that can influence the decision on whether to provide seafood during early years' feeding using a multi-method qualitative study design. A total of 26 discussions posted by mothers on parenting websites; Mumknowsbest, Mumsnet and Netmums, accessed July 2013, together with discussions from six focus groups (February-July 2014) in the North East of Scotland were included for thematic qualitative analysis. Discussions on the inclusion of seafood during the early years were centred across four interrelating themes; - food-related attributes, mother-centred aspects, family-centred aspects, and external information sources. Concerns regarding safety and mothers' limited knowledge and skills on seafood were apparent from discussions; however, the practicalities of providing a cost effective family meal were also issues raised by mothers. An understanding of the numerous and sometimes contradictory influences on mothers' decisions to include seafood during early years' period could be used to develop strategies to help increase regular seafood consumption. In particular, ensuring formal information and guidance clearly addresses the safety concerns of mothers and the development of practical education schemes to encourage and teach cooking skills should be considered.

Something fishy about home-cooked infant feeding recipes.

There is no evidence available indicating whether popular infant and young child feeding (IYCF) cookbooks provide nutritious options for home-cooking, what the most common food types are within the recipes, and what accompanying dietary advice is provided to parents. This study surveyed available IYCF cookbooks from local libraries and Amazon UK's top 20 bestsellers (May to July 2013 to examine the prevalence and nutritional content of cookbook recipes comparing these to recommendations whilst investigating the messages portrayed towards parents on giving different foods to their child during IYCF. Vegetable-based recipes (median=29) predominated main-meal options while a proportional number of red meat, poultry and seafood-based recipes were included providing parents with options of protein-rich recipes for their young child. These home-cooked recipes adequately met or exceeded age-specific dietary recommendations. Mixed messages were apparent on the inclusion of foods during IYCF within and across these cookbooks, in particular for seafood, highlighting a lack of consistent advice portrayed to parents during the early years. Community-based health professionals should advise parents of the inconsistent and incorrect messages on food inclusion portrayed in some IYCF cookbooks and guide them towards formal recommendations.
