An analysis of food and beverage advertising on bus shelters in a deprived area of Northern England

Objective: To quantify the extent of food and beverage advertising on bus shelters in a deprived area of the UK, to identify the healthfulness of advertised products, and any differences by level of deprivation. The study also sought to assess the creative strategies used and extent of appeal to young people. Design: Images of bus shelter advertisements were collected via in person photography (in 2019) and Google Street View (photos recorded in 2018). Food and beverage advertisements were grouped into one of seventeen food categories and classified as healthy/less healthy using the UK Nutrient Profile Model. The deprivation level of the advertisement location was identified using the UK Index of Multiple Deprivation. Setting: Middlesbrough and Redcar and Cleveland in South Teesside. Participants: N/A Results: 832 advertisements were identified, almost half (48.9%) of which were for foods or beverages. Of food and non-alcoholic beverage adverts, 35.1% were less healthy. Most food advertisements (98.9%) used at least one of the persuasive creative strategies. Food advertisements were found to be of appeal to children under 18 years (71.9%). No differences in healthiness of advertised foods were found by level of deprivation. Conclusions: Food advertising is extensive on bus shelters in parts of the UK, and a substantial proportion of this advertising is classified as less healthy and would not be permitted to be advertised around television programming for children. Bus shelter advertising should be considered part of the UK policy deliberations around restricting less healthy food marketing exposure.

Developing a fast-track COVID-19 vaccination clinic for pregnant people

A pilot fast-track COVID-19 vaccination clinic was created in the east of England to provide expert advice, education and support for pregnant people. As the COVID-19 pandemic has progressed, it is clear that pregnant people are at high risk of becoming seriously unwell with the COVID-19 virus. Establishment of the clinic led to a 20% increase in COVID-19 vaccine uptake in this group, with 211 vaccinations between 28 June and 30 September 2021. Almost two-thirds (59%) of pregnant people reported they would not have taken up the vaccination if they had not discussed it as part of this service. Over half of those attending (50.2%) reside within the index of multiple deprivation levels 1–4, the most severely deprived areas. This article explores the development of the fast-track vaccination service and seeks to support others wishing to replicate its delivery in their areas.

Comparative effectiveness of ChAdOx1 versus BNT162b2 vaccines against SARS-CoV-2 infections in England and Wales: A cohort analysis using trial emulation in the Virus Watch community data

Introduction: Infections of SARS-CoV-2 in vaccinated individuals have been increasing globally. Understanding the associations between vaccine type and a post-vaccination infection could help prevent further COVID-19 waves. In this paper, we use trial emulation to understand the impact of a phased introduction of the vaccine in the UK driven by vulnerability and exposure status. We estimate the comparative effectiveness of COVID-19 vaccines (ChAdOx1 versus BNT162b2) against post-vaccination infections of SARS-CoV-2 in a community setting in England and Wales. Method: Trial emulation was conducted by pooling results from six cohorts whose recruitment was staggered between 1st January 2021 and 31st March 2021 and followed until 12th November 2021. Eligibility for each trial was based upon age (18+ at the time of vaccination), without prior signs of infection or an infection within the first 14 days of the first dose. Time from vaccination of ChAdOx1 or BNT162b2 until SARS-CoV-2 infection (positive polymerase chain reaction or lateral flow test after 14 of the vaccination) was modelled using Cox proportional hazards model for each cohort and adjusted for age at vaccination, gender, minority ethnic status, clinically vulnerable status and index of multiple deprivation quintile. For those without SARS-CoV-2 infection during the study period, follow-up was until loss-of-follow-up or end of study (12th November 2021). Pooled hazard ratios were generated using random-effects meta-analysis. Results: Across six cohorts, there were a total of 21,283 participants who were eligible and vaccinated with either ChAdOx1 (n = 13,813) or BNT162b2 (n = 7,470) with a median follow-up time of 266 days (IQR: 235 - 282). By November 12th 2021, 750 (5.4%) adults who had ChAdOx1 as their vaccine experienced a SARS-CoV-2 infection, compared to 296 (4.0%) who had BNT162b2. We found that people who received ChAdOx1 vaccinations had 10.54 per 1000 people higher cumulative incidence for SARS-CoV-2 infection compared to BNT162b2 for infections during a maximum of 315 days of follow-up. When adjusted for age at vaccination, sex, minority ethnic status, index of multiple deprivation, and clinical vulnerability status, we found a pooled adjusted hazard ratio of 1.35 [HR: 1.35, 95%CI: 1.15 - 1.58], demonstrating a 35% increase in SARS-CoV-2 infections in people who received ChAdOx1 compared to BNT162b2. Discussion: We found evidence of greater effectiveness of receiving BNT162b2 compared to ChAdOx1 vaccines against SARS-CoV-2 infection in England and Wales during a time period when Delta became the most prevalent variant of concern. Our findings demonstrate the importance of booster (third) doses to maintain protection and suggest that these should be prioritised to those who received ChAdOx1 as their primary course.

P-OGC77 Why curative treatment rates are so low for stage I/II Oesophago-gastric cancer in the West of Scotland? – A five year review

Background Over the last decade, quality performance indicators (QPIs) have been used to drive improvements in cancer care in Scotland. QPI-11 targets curative treatment rates for oesophago-gastric (OG) cancer and this target has been consistently missed. This study aimed to investigate why patients with potentially curable Stage I and II OG cancer did not receive curative treatment. Methods The West of Scotland MCN database was interrogated for patients with newly diagnosed stage I and II OG cancer between January 2015 and December 2019 to identify those patients who did not have curative treatment. Electronic records were then analyzed and the reason for the non curative treatment recorded. Results 260 patients (mean age 78.3 ± 9 years; 114 (43.8%) female) were identified. Median Scottish Index of Multiple Deprivation was 4 (IQR 2-7). There were 159 (61.2%) oesophageal cancers, 196 (75.4%) adenocarcinomas and 174 (66.9%) were Stage II cancers. Formal CPEX fitness was assessed in only 20 patients (7.7%). Reasons for curative treatment not being received were as follows: not clinically fit (n = 216 (83.1%)); patient declined curative treatment (n = 17 (6.5%)); disease progression (n = 16 (6.2%)) and identification of synchronous cancers (n = 9 (3.5%)). Conclusions Lack of fitness for radical treatment is the predominant reason for Stage I and II OG cancer patients in the West of Scotland not being treated with curative intent. This may be related to the previously described “West of Scotland” effect on health comorbidities.

P-O08 Effect of socioeconomic deprivation on clinical characteristics and outcomes of patients undergoing an emergency appendectomy

Background Appendicectomy is one of the commonest emergency general surgical operations performed. Previous studies have shown that socioeconomic status (SES) impact outcomes in a number of diseases. Currently, there is no study analysing the impact of SES on the outcome of appendectomy. Our aim was to compare the clinical characteristics and outcomes of adults having an emergency appendectomy between deprived and less deprived SES groups. Methods A multicentre retrospective observational study of all adult patients who had an emergency appendectomy across four hospitals (two district general and two tertiary care hospitals) between August 2018 and November 2020 was performed. Patients were identified through pathology records. Data was extracted from electronic records for demographics, pre-operative (peak) blood results, pre and post-operative imaging, operative details and the clinical outcomes. Patient’s residential address was used to calculate Scottish Index of Multiple Deprivation (SIMD). The patients were grouped by SIMD into a more deprived SES group (SIMD 1-5) and a less deprived SES group (SIMD 6-10) and results compared. Results A total of 1,105 patients (57.5% male) were included. Median age was lower in the more deprived group (35 vs 40 years, p < 0.001). The less deprived group were more likely to be fitter: ASA-1 grade 51.6% vs 43.5%, p = 0.008. There were fewer appendectomies in most deprived decile compared to the least deprived decile (5.2 vs 11.3 per 10,000 population per year, p < 0.001). There was no difference in inflammatory markers, pre-operative imaging, surgical approach, severity of appendicitis and the median length of stay (3 days). However, there were more surgical site infection in the more deprived group (3.4% vs 0.9%, p = 0.006). Conclusions This study demonstrates that SES does impact on the age of presentation and incidence of appendectomy. Surgical site infection were seen more frequently in the more deprived patients undergoing emergency appendectomy. This may be a reflection of the underlying comorbidities.

Scottish Index of Multiple Deprivation (SIMD) Indicators as Predictors of Mortality Among Patients Hospitalised with COVID-19 Disease in the Lothian Region, Scotland During the First Wave: A Cohort Study

Background: Sars-CoV-2, the causative agent of COVID-19, has led to more than 100,000 deaths in the UK and multiple risk factors for mortality including age, sex and deprivation have been identified. This study aimed to identify which indicators of Scottish Index of Multiple Deprivation (SIMD), an area-based deprivation index, were predictive of mortality. Methods: This was a prospective cohort study of anonymised electronic health records of 710 consecutive patients hospitalised with Covid-19 disease between March and June 2020 in the Lothian Region of Southeast Scotland. Data sources included automatically extracted data from national electronic platforms and manually extracted data from individual admission records. Exposure variables of interest were SIMD quintiles and more specifically 12 indicators of deprivation deemed clinically relevant selected from the SIMD. Our primary outcome was mortality. Univariable and multivariable logistic regression analyses adjusted for age and sex were used to determine measures of association between exposures of interest and the primary outcome. Results: After adjusting for age and sex, we found an increased risk of mortality in the more deprived SIMD quintiles 1 and 3 (OR 1.75, CI 0.99-3.08, p=0.053 and OR 2.17, CI 1.22-3.86, p=0.009, respectively), but this association was not significant in our multivariable model adjusted for co-morbidities and clinical parameters of severity at admission. Of the 12 pre-selected indicators of deprivation, two were associated with greater mortality in our multivariable analysis: income deprivation rate categorised by quartile (Q4 (most deprived): 2.11 (1.20-3.77) p=0.011)) and greater than expected hospitalisations due to alcohol per SIMD data zone (1.96 (1.28-3.00) p=0.002)). Conclusions: In contrast to other studies, deprivation quintile distribution was not predictive of mortality in our cohort. This possibly reflects the greater affluence and ethnic homogeneity of the Lothian Region compared to the rest of Scotland. We identified an increased risk of mortality in patients residing in areas with greater income-deprivation and/or number of hospitalisations due to alcohol. In areas where aggregate measures fail to capture pockets of deprivation, specific indicators may be helpful in targeting resources to residents at risk of poorer outcomes from Covid-19.

Associations between dietary patterns and metabolic syndrome in older adults in New Zealand: the REACH study

Metabolic syndrome is common in older adults and may be modified by the diet. The aim of this study was to examine associations between a posteriori dietary patterns and metabolic syndrome in an older New Zealand population. The REACH study (Researching Eating, Activity, and Cognitive Health) included 366 participants (65-74 years, 36% male) living independently in Auckland, New Zealand. Dietary data were collected using a 109-item food frequency questionnaire with demonstrated validity and reproducibility for assessing dietary patterns using principal component analysis. Metabolic syndrome was defined by the National Cholesterol Education Program Adult Treatment Panel III. Associations between dietary patterns and metabolic syndrome, adjusted for age, sex, index of multiple deprivation, physical activity, and energy intake were analysed using logistic regression analysis. Three dietary patterns explained 18% of dietary intake variation – ‘Mediterranean style’ (salad/leafy cruciferous/other vegetables, avocados/olives, alliums, nuts/seeds, shellfish and white/oily fish, berries), ‘prudent’ (dried/fresh/frozen legumes, soy-based foods, whole grains, carrots), and ‘Western’ (processed meat/fish, sauces/condiments, cakes/biscuits/puddings, meat pies/hot chips). No associations were seen between ‘Mediterranean style’ [OR=0.75 (95% CI 0.53, 1.06), P=0.11] or ‘prudent’ [OR=1.17 (95% CI 0.83, 1.59), P=0.35] patterns and metabolic syndrome after co-variate adjustment. The ‘Western’ pattern was positively associated with metabolic syndrome [OR=1.67 (95% CI 1.08, 2.63), P=0.02]. There was also a small association between an index of multiple deprivation [OR=1.04 (95% CI 1.02, 1.06), P<0.001] and metabolic syndrome. This cross-sectional study provides further support for a Western dietary pattern being a risk factor for metabolic syndrome in an older population.

Marked and widening socioeconomic inequalities in type 2 diabetes prevalence in Scotland

BackgroundThis study investigated the association between socioeconomic status and type 2 diabetes (T2D) prevalence in Scotland in 2021 and tested the null hypothesis that inequalities had not changed since they were last described for 2001–2007.MethodsData from a national population-based diabetes database for 35-to-84-year-olds in Scotland for 2021 and mid-year population estimates for 2019 stratified by sex and fifths of the Scottish Index of Multiple Deprivation were used to calculate age-specific prevalence of T2D. Age-standardised prevalence was estimated using the European Standard Population with relative risks (RRs) compared between the most (Q1) and least (Q5) deprived fifths for each sex, and compared against similar estimates from 2001 to 2007.ResultsComplete data were available for 255 764 people (98.9%) with T2D. Age-standardised prevalence was lowest for women in Q5 (3.4%) and highest for men in Q1 (11.6%). RRs have increased from 2.00 (95% CI 1.52 to 2.62) in 2001–2007 to 2.48 (95% CI 2.43 to 2.53) in 2021 for women and from 1.58 (95% CI 1.20 to 2.07) in 2007 to 1.89 (95% CI 1.86 to 1.92) in 2021 for men.ConclusionsSocioeconomic inequalities in T2D prevalence have widened between 2001–2007 and 2021. Further research is required to investigate potential medium-term effects of the COVID-19 pandemic.

TP6.2.16General practitioner compliance with Scottish cancer referral guideline for Oesophago-gastric cancer

Aims The outcome of oesophago-gastric cancer is often poor. Timely referral of suspected cancer is essential for early diagnosis and optimal outcome. This study aims to audit the General Practitioners (GPs) compliance with the Scottish referral guidelines for suspected oesophago-gastric cancer. Methods A retrospective cohort study of all newly diagnosed oesophago-gastric cancers who were referred from the primary care and discussed in a single regional MDT was performed between October 2019 and September 2020. Electronic records were interrogated and symptomatology audited against the Scottish cancer referral guidelines. Results Of the 349 patients, 227 (65.0%) were referred from the primary care. 150 (66.1%) were male and the mean age was 69.5 ± 10.9 years. Mean Scottish Index of Multiple Deprivation was 5 ± 3. 149 (65.6%) had dysphagia and/or odynophagia and 181 (79.7%) were oesophageal cancers. 67 (29.5%) were T4 disease and 87 (38.3%) were metastatic at presentation. Urgency of referral was: 25 (11.0%) routine, 54 (23.7%) urgent and 148 (65.2%) Urgent Suspicion of Cancer (USOC). 192 (84.6%) patients qualified to be referred as USOC, of these 138 (71.9%) were actually referred as USOC. Of the 35 (15.4%) patients who did not qualify for the USOC referral, 10 (28.6%) patients were referred as USOC. The sensitivity was 71.9% and specificity 71.4%. Conclusions GP compliance with the adherence with the National guidelines remains a barrier in the USOC in oesophago-gastric cancer. Further GP education and awareness is required to improve their compliance.

There were 46 (56.8%) oesophageal cancers, 49 (60.5%) adenocarcinomas and 63 (77.8%) were Stage II cancers. Formal CPEX fitness was assessed in only 6 patients (7.4%). Reasons for curative treatment not being received were as follows: not clinically fit (n = 69 (85.2%)); patient declined curative treatment (n = 7 (8.6%)); disease progression (n = 3 (3.7%)) and identification of synchronous cancers (n = 2 (2.5%)). 61 patients (75.3%) are deceased at the time of analysis, with a median time from MDT discussion to death of 6 (IQR 2-11.5) months. Conclusions Lack of fitness for radical treatment is the predominant reason for Stage I and II OG cancer patients in the West of Scotland not being treated with curative intent. This may be related to the previously described “West of Scotland” effect on health comorbidities.
