COVID-19 Outcomes in Minority Ethnic Groups: Do Obesity and Metabolic Risk Play a Role?

PURPOSE OF REVIEW: Globally, minority ethnic groups have been at higher risk of COVID-19 mortality and morbidity than majority populations. This review outlines factors that may interact to create these inequalities and explores the hypothesis that differing levels of cardio-metabolic risk, according to ethnic group, play a role. RECENT FINDINGS: Two UK Biobank studies have reported that the body mass index is more strongly associated with an increased risk of COVID-19 infection and mortality in minority ethnic populations than in White populations. A study of UK patients found that the strongest association between obesity and adverse COVID-19 outcomes was in people of Black ethnicity. Differences in the prevalence of obesity and its metabolic sequelae have been shown to partly mediate ethnic inequalities in COVID-19 outcomes, although not always consistently. It is possible that ethnic differences in the consequences of obesity may explain some of the remaining disparity in COVID-19 risk.

Impact of national COVID-19 restrictions on incidence of notifiable communicable diseases in England: an interrupted time series analysis.

BACKGROUND: Non-pharmaceutical interventions (NPIs), such as travel restrictions, social distancing and isolation policies, aimed at controlling the spread of COVID-19 may have reduced transmission of other endemic communicable diseases, such as measles, mumps and meningitis in England. METHODS: An interrupted time series analysis was conducted to examine whether NPIs was associated with trends in endemic communicable diseases, using weekly reported cases of seven notifiable communicable diseases (food poisoning, measles, meningitis, mumps, scarlet fever and pertussis) between 02/01/2017 to 02/01/2021 for England. RESULTS: Following the introduction of COVID-19 restrictions, there was an 81.1% (95% CI; 77.2-84.4) adjusted percentage reduction in the total number of notifiable diseases recorded per week in England. The greatest decrease was observed for measles, with a 90.5% percentage reduction (95% CI; 86.8-93.1) from 42 to 5 cases per week. The smallest decrease was observed for food poisoning, with a 56.4% (95%CI; 42.5-54.2) decrease from 191 to 83 cases per week. CONCLUSIONS: A total reduction in the incidence of endemic notifiable diseases was observed in England following the implementation of public health measures aimed at reducing transmission of SARS-COV-2 on March 23, 2020. The greatest reductions were observed in diseases most frequently observed during childhood that are transmitted via close human-to-human contact, such as measles and pertussis. A less substantive reduction was observed in reported cases of food poisoning, likely due to dining services (i.e., home deliveries and takeaways) remaining open and providing a potential route of transmission. This study provides further evidence of the effectiveness of non-pharmaceutical public health interventions in reducing the transmission of both respiratory and food-borne communicable diseases.

How can childhood obesity prevention policy be more effective and equitable following the COVID-19 pandemic?

BackgroundDespite being a public health priority in the UK for decades, rates of childhood obesity are continuing to rise along highly unequal lines. Investigating how families have engaged with food and food environments throughout the COVID-19 pandemic provides an opportunity to understand the conditions which shape peoples’ ability to consume nutritious diets.MethodsWe conducted a remote longitudinal qualitative study, engaging 62 parents of school or nursery age children across three case study sites in England;Bradford, Folkestone and London Borough of Brent. Participants were recruited purposively to represent the demographics of each study site and comprise a range of family structures. Methods informed by ethnographic and participatory approaches were adapted for a remote setting. These comprised: semi-structured interviews, photo-elicitation, participatory mapping, and oral diaries. Participants engaged with these methods three times at six-month intervals between October 2020 and December 2021. Data from each time point was analysed cross-sectionally and the whole data set longitudinally using trajectory analysis.ResultsCOVID-19 and its early impacts necessitated a reorganisation of daily routines and food practices, an adjustment of existing food practices, and/or an establishment of new ones. Some of these changes persisted beyond the context of lockdowns, such as households who had pivoted to alternative means of sourcing food (e.g. vegetable boxes) initially to avoid COVID-19 transmission maintaining this long-term due to perceived cost-saving and health benefits. Other changes were largely confined to the context of lockdown, such as the use of baking and cooking from scratch to provide entertainment in the absence of other opportunities for leisure. Households’ ability to enact and maintain practices beneficial for both nutrition and wellbeing was dictated by the availability of finances, time and social support systems. Changes to diet perceived as negative came about through financial insecurity, the gendered division of care work and mental health impacts associated with this burden.ConclusionCOVID-19 has revealed the multiple resources and systems of support that underpin families’ ability to eat well and, when disrupted, can limit capacity to procure and prepare nutritious foods. These contexts have the capacity to occur again both on a large scale in society (e.g. financial recessions and periods of food system disruption) and in the context of an individual’s lifetime (e.g. ill health, job loss or loss of social support networks). Policy now has a window of opportunity to implement learnings from this period and shape obesity prevention policy to be more effective and equitable.

Implementation of novel and conventional outbreak control measures in managing COVID-19 outbreaks in a large UK prison.

BACKGROUND: Outbreak control measures during COVID-19 outbreaks in a large UK prison consisted of standard (e.g., self-isolation) and novel measures, including establishment of: (i) reverse cohorting units for accommodating new prison admissions; (ii) protective isolation unit for isolating symptomatic prisoners, and (iii) a shielding unit to protect medically vulnerable prisoners. METHODS: Single-centre prospective longitudinal study (outbreak control study), implementing novel and traditional outbreak control measures to prevent a SARS-COV-2 outbreak. The prison held 977 prisoners and employed 910 staff at that start of the outbreak. RESULTS: 120 probable and 25 confirmed cases among prisoners and staff were recorded between March and June 2020 during the first outbreak. Over 50% of initial cases among prisoners were on the two wings associated with the index case. During the second outbreak, 182 confirmed cases were recorded after probable reintroduction from a staff member. Widespread testing identified 145 asymptomatic prisoners, 16.9% of the total prisoner cases. The cohorting units prevented re-infection from new prison admissions and the shielding unit had no COVID-19 infections linked to either outbreak. CONCLUSIONS: Identifying and isolating infected prisoners, cohorting new admissions and shielding vulnerable individuals helped prevent uncontrollable spread of SARS-COV-2. These novel and cost-effective approaches can be implemented in correctional facilities globally.

Food shortages, stockpiling and panic buying ahead of Brexit as reported by the British media: a mixed methods content analysis.

BACKGROUND: On 23 June 2016, the United Kingdom voted to leave the European Union. From that date until the UK left the EU in January 2021, there were frequent warnings from industry and government sources of potential disruption to the food supply chain and possible food shortages. Over this period, the media had an important role in communicating on the potential impacts of Brexit. This study examines how food supply and demand, in the context of Brexit, was portrayed by the British media. METHODS: The study consisted of two components: (1) a quantitative analysis measuring frequency of reporting and information sources for articles on food supply and demand in the context of Brexit, in three daily newspapers, between January 2015 and January 2020; and (2) a content analysis exploring key themes and media framing of relevant issues in a subset of articles. RESULTS: Reports by the media about the impact of Brexit on the UK food system were largely absent in the six months before the UK voted to leave the EU in June 2016, increasing in frequency from mid-2018 onward, peaking in mid-2019 following the appointment of Boris Johnson as prime minister. Five themes were developed from included articles: food shortages/panic buying (appearing in 96% of articles); food chain disruption (86%); economic impacts (80%); preparation and stockpiling by the government/food sector (63%) and preparation and stockpiling by individuals (22%). CONCLUSION: Government messaging sought to reassure the public that even under a worst-case scenario there would be no food shortages. These messages, however, contradicted warnings in the media of disruption to the food supply chain and food shortages. The media further reinforced this narrative of potential food shortages by reporting on the experiences of those preparing for Brexit by stockpiling food. The media must consider the impact of their messaging on public behaviour, as even imagined food shortages can instigate stockpiling and panic buying behaviour, as observed during the COVID-19 pandemic.
