Metabolic changes with intermittent fasting.

BACKGROUND: The prevalence of obesity is rising globally and effective strategies to treat obesity are needed. Intermittent fasting, a dietary intervention for weight management, has received growing interest from the general public, as well as healthcare professionals, as a form of lifestyle intervention. METHODS: We executed a rapid review using PUBMED database to identify systematic reviews that examined the impact of intermittent fasting on metabolic indices, published between 2011 and 2022. RESULTS: Intermittent fasting leads to weight loss of a similar magnitude to continuous energy restriction. Most of the evidence shows that intermittent fasting leads to greater fat loss as measured by fat mass (kg) or body fat percentage compared to an ad libitum diet, but fat loss attained during intermittent fasting is not significantly different to continuous energy restriction, although recent evidence shows intermittent fasting to be superior. There is mixed evidence for the impact of intermittent fasting on insulin resistance, fasting glucose and lipid profile. Some studies focused on populations of Muslim people, which showed that Ramadan fasting may lead to weight loss and improvement of metabolic parameters during fasting, although the effects are reversed when fasting is finished. CONCLUSIONS: Intermittent fasting is more effective than an ad libitum dietary intake, and equally or more effective as continuous energy restriction, for weight management. However, there is inconclusive evidence on whether intermittent fasting has a clinically beneficial effect on glucose and lipid metabolism.

Critical analysis of tobacco taxation policies in Pakistan after two decades of FCTC: Policy gaps and lessons for low- and middle-income countries.

INTRODUCTION: Tobacco taxation remains a poorly used intervention to control tobacco use in many low- and middle-income countries (LMICs) including Pakistan even after two decades of FCTC adoption. This study identifies gaps and implementation challenges in the current Tobacco Taxation and Pricing Policies (TTPP) in Pakistan, and highlights key policy implications and lessons for LMICs to strengthen tobacco control measures. METHODS: We used qualitative document analysis to examine the policy documents to assess the TTPP against the WHO Framework Convention on Tobacco Control (FCTC) guidelines for the implementation of Article 6 of the FCTC. In addition, we used secondary data on tobacco tax and prices to assess the impact of TTPP on tobacco affordability in the country. RESULTS: Although Pakistan taxes raw tobacco, cigarettes and other tobacco products (cigarillos, cigars, cheroots), the existing TTPP falls below the WHO FCTC requirements of: uniform tax level, simple tax structure and 70% share of excise tax in the price of a product's pack; among others. There are also multiple issues in tobacco tax administration such as lack of monitoring. This is leading to the availability of highly affordable tobacco products in the country. CONCLUSIONS: Pakistan does not have a clear strategy on using tobacco taxation and prices as a public health tool in the country. Existing TTPP face dual issues of flawed structure and poor administration translating into highly affordable tobacco products and low revenues in the country. There is a need to introduce multisectoral tobacco control policies in countries like Pakistan in the context of the tobacco sector political economy.

How and to what extent did the Coventry City of Culture 'City Host' volunteer programme effect the volunteers' mental wellbeing? A qualitative study.

BACKGROUND: A team of volunteers, known as City Hosts, were recruited to support UK City of Culture 2021 awarded to Coventry. City Hosts held various roles facilitating cultural event delivery and promoting a positive experience for visitors. This study aimed to (i) understand how and to what extent the volunteering programme impacted volunteer subjective wellbeing, and (ii) explore the mechanisms of change and intermediate outcomes between volunteering and subjective wellbeing. METHODS: This qualitative study comprised inductive and deductive analysis of data collected through semi-structured interviews, conducted between December 2021-May 2022 with City Hosts. This was complimented with secondary qualitative analysis of free text responses within Monitoring and Evaluation data collected from City Hosts in surveys conducted in August and November 2021, and April 2022. RESULTS: Approximately 180 City Hosts responded to the free text questions in each survey and 27 completed interviews. Analysis of data collected from City Hosts suggested positive wellbeing impacts from volunteering and supported theorised pathways to improved wellbeing. Strengths of the City Host programme included (i) facilitating the full range of mechanisms of change that mediate improved volunteer wellbeing, particularly promoting social connections and developing a strong role and group identity and (ii) flexibility around what volunteers do, how much, and how often. CONCLUSIONS: This study offers lessons for others designing volunteering programmes who wish to promote wellbeing among associated volunteers. We also offer evidence that exposure to culture may be one mechanism by which volunteering can improve wellbeing.

Meat versus meat alternatives: which is better for the environment and health? A nutritional and environmental analysis of animal-based products compared with their plant-based alternatives.

BACKGROUND: Poor diets lead to negative health outcomes, including increased risk of noncommunicable diseases. Food systems, most notably agriculture, contribute to greenhouse gas emissions (GHGE) that lead to climate change. Meat consumption plays a role in both health and environmental burden. Consumption of meat alternatives may reduce these harms. The aim was to compare meat products and their plant-based alternatives on nutritional parameters, GHGE and price to examine if it is feasible and beneficial for policymakers and health professionals to recommend meat alternatives. METHODS: Data on nutritional information and cost for 99 selected products were collected from five UK supermarkets. Estimates for GHGEs for 97 of these products were found through secondary articles. Median values for nutritional value, GHGE (kgCO2 e) and price per 100 g were calculated to allow comparisons between meat products and their alternatives. Mann-Whitney U tests were used to look for significant differences for each nutrient, emissions and price. RESULTS: Meat alternatives contained significantly more fibre and sugar and were significantly higher in price compared to the equivalent meat products. Meat alternatives had a significantly lower number of calories, saturated fat, protein and kgCO2 e than meat products. There was no significant difference in the amount of salt between meat and meat alternatives. CONCLUSIONS: Overall, this paper found that meat alternatives are likely to be better for health according to most parameters, while also being more environmentally friendly, with lower GHGEs. However, the higher price of these products may be a barrier to switching to meat alternatives for the poorest in society.

Trends in socioeconomic inequalities in behavioural non-communicable disease risk factors: analysis of repeated cross-sectional health surveys in England between 2003 and 2019.

BACKGROUND: Previous studies have shown that those in lower socioeconomic positions (SEPs) generally have higher levels of behavioural non-communicable disease (NCD) risk factors. However, there are limited studies examining recent trends in inequalities. This study examined trends in socioeconomic inequalities in NCD behavioural risk factors and their co-occurrence in England from 2003-19. METHODS: This time-trend analysis of repeated cross-sectional data from the Health Survey for England examined the relative index of inequalities (RII) and slope index of inequalities (SII) in four NCD behavioural risk factors: smoking; drinking above recommended limits; insufficient fruit and vegetables consumption; and physical inactivity. FINDINGS: Prevalence of risk factors has reduced over time, however, this has not been consistent across SEPs. Absolute and relative inequalities increased for physical inactivity; relative inequalities also increased for smoking; for insufficient fruit and vegetable consumption, the trends in inequalities depended on SEPs measure. Those in lower SEPs experienced persistent socioeconomic inequalities and clustering of behavioural risk factors. In contrast, those in higher SEPs had higher prevalence of excessive alcohol consumption; this inequality widened over the study period. INTERPRETATION: Inequalities in smoking and physical inactivity are persisting or widening. The pattern of higher drinking in higher SEPs obscure the fact that the greatest burden of alcohol-related harm falls on lower SEPs. Policy attention is required to tackle increasing inequalities in smoking prevalence, low fruit and vegetable consumption and physical inactivity, and to reduce alcohol harm.

National Health Examination Surveys: an essential piece of the health planning puzzle.

National health examination surveys (HESs) have been developed to provide important information that cannot be obtained from other sources. A HES combines information obtained by asking participants questions with biophysical measurements taken by trained field staff. They are observational studies with the highest external validity and make specific contributions to both population (public health) and individual health. Few countries have a track record of a regular wide-ranging HES, but these are the basis of many reports and scientific papers. Despite this, little evidence about HES usefulness and impact or the factors that influence HES effectiveness have been disseminated. This paper presents examples of HES contributions to society in both Europe and the Americas. We sought information by emailing a wide list of people involved in running or using national HESs across Europe and the Americas. We asked for examples of where examination data from their HES had been used in national or regional policymaking. We found multiple examples of HES data being used for agenda-setting, including by highlighting nutritional needs and identifying underdiagnosis and poor management of certain conditions. We also found many ways in which HES have been used to monitor the impact of policies and define population norms. HES data have also been used in policy formation and implementation. HES data are influential and powerful. There is need for global support, financing and networking to transfer capacities and innovation in both fieldwork and laboratory technology.

Swahili translation and validation of the Warwick Edinburgh Mental Wellbeing Scale (WEMWBS) in adolescents and adults taking part in the girls' education challenge fund project in Tanzania.

BACKGROUND: The Warwick Edinburgh Mental Wellbeing Scale (WEMWBS) is validated for measuring mental wellbeing in populations aged 11 + and has been translated into 30 + languages. The aims of this study were a) to translate and validate WEMWBS for use in Swahili-speaking populations to facilitate measurement and understanding of wellbeing, evaluation of policy and practice, and enable international comparisons; and b) to examine sociodemographic characteristics associated with higher and lower mental wellbeing in participants in the Girls' Education Challenge (GEC) project in Tanzania. METHODS: A short questionnaire including WEMWBS and similar scales for comparison, socio-demographic information, and self-reported health was translated into Swahili using gold standard methodology. This questionnaire was used to collect data from secondary school students, learner guides, teacher mentors and teachers taking part in the GEC project in Tanzania. Focus groups were used to assess acceptability and comprehensibility of WEMWBS and conceptual understanding of mental wellbeing. These were audio-taped, transcribed and analysed thematically. Internal consistency of WEMWBS, correlation with comparator scales and confirmatory factor analysis were completed as quantitative validation. Finally, multivariable logistic regression was used to explore associations between individual characteristics and 'high' and 'low' mental wellbeing, defined as the highest and lowest quartile of WEMWBS scores. RESULTS: 3052 students and 574 adults were recruited into the study. Participants reported that WEMWBS was understandable and relevant to their lives. Both WEMWBS and its short form met quantitative standards of reliability and validity, were correlated with comparator scales and met the criteria to determine a single factor structure. For students in the GEC supported government schools: mental wellbeing was higher in students in the final two 'forms' of school compared with the first two. In addition: being male, urban residence, the absence of markers of social marginality and better self-reported health were all significantly associated with better mental wellbeing. For adults, urban residence and better self-reported health were associated with better mental wellbeing. CONCLUSIONS: The Swahili translation of WEMWBS is available for use. Further work to explore how to intervene to increase mental wellbeing in vulnerable GEC participants is needed.

Gender differences in active travel in major cities across the world.

There is lack of literature on international comparison of gender differences in the use of active travel modes. We used population-representative travel surveys for 19 major cities across 13 countries and 6 continents, representing a mix of cites from low-and-middle income (n = 8) and high-income countries (n = 11). In all the cities, females are more likely than males to walk and, in most cities, more likely to use public transport. This relationship reverses in cycling, with females often less likely users than males. In high cycling cities, both genders are equally likely to cycle. Active travel to access public transport contributes 30-50% of total active travel time. The gender differences in active travel metrics are age dependent. Among children (< 16 years), these metrics are often equal for girls and boys, while gender disparity increases with age. On average, active travel enables one in every four people in the population to achieve at least 30 min of physical activity in a day, though there is large variation across the cities. In general, females are more likely to achieve this level than males. The results highlight the importance of a gendered approach towards active transport policies. Such an approach necessitates reducing road traffic danger and male violence, as well as overcoming social norms that restrict women from cycling.

A systematic review of the burden of, access to services for and perceptions of patients with overweight and obesity, in humanitarian crisis settings.

INTRODUCTION: Excess body weight causes 4 million deaths annually across the world. The number of people affected by humanitarian crises stands at a record high level with 1 in 95 people being forcibly displaced. These epidemics overlap. Addressing obesity is a post-acute phase activity in non-communicable disease management in humanitarian settings. Information is needed to inform guidelines and timing of interventions. The objective of this review was to explore the prevalence of overweight and obesity in populations directly affected by humanitarian crises; the cascade of care in these populations and perceptions of patients with overweight and obesity. METHODS: Literature searches were carried out in five databases. Grey literature was identified. The population of interest was non-pregnant, civilian adults who had experience of humanitarian crises (armed conflict, complex emergencies and natural disasters). All study types published from January 1st, 2011, were included. Screening, data extraction and quality appraisal were carried out in duplicate. A narrative synthesis is presented. RESULTS: Fifty-six reports from forty-five studies were included. Prevalence estimates varied widely across the studies and by subgroups. Estimates of overweight and obesity combined ranged from 6.4% to 82.8%. Studies were heterogenous. Global distribution was skewed. Increasing adiposity was seen over time, in older adults and in women. Only six studies were at low risk of bias. Body mass index was the predominant measure used. There were no studies reporting cascade of care. No qualitative studies were identified. CONCLUSION: Overweight and obesity varied in crisis affected populations but were rarely absent. Improved reporting of existing data could provide more accurate estimates. Worsening obesity may be prevented by acting earlier in long-term crises and targeting risk groups. The use of waist circumference would provide useful additional information. Gaps remain in understanding the existing cascade of care. Cultural norms around diet and ideal body size vary.

Health inequalities in infectious diseases: a systematic overview of reviews.

OBJECTIVES: The aim of this systematic overview of reviews was to synthesise available evidence on inequalities in infectious disease based on three dimensions of inequalities; inclusion health groups, protected characteristics and socioeconomic inequalities. METHODS: We searched MEDLINE, Embase, Web of Science and OpenGrey databases in November 2021. We included reviews published from the year 2000 which examined inequalities in the incidence, prevalence or consequences of infectious diseases based on the dimensions of interest. Our search focused on tuberculosis, HIV, sexually transmitted infections, hepatitis C, vaccination and antimicrobial resistance. However, we also included eligible reviews of any other infectious diseases. We appraised the quality of reviews using the Assessment of Multiple Systematic Reviews V.2 (AMSTAR2) checklist. We conducted a narrative data synthesis. RESULTS: We included 108 reviews in our synthesis covering all the dimensions of inequalities for most of the infectious disease topics of interest, however the quality and volume of review evidence and consistency of their findings varied. The existing literature reviews provide strong evidence that people in inclusion health groups and lower socioeconomic status are consistently at higher risk of infectious diseases, antimicrobial resistance and incomplete/delayed vaccination. In the protected characteristics dimension, ethnicity, and sexual orientation are important factors contributing to inequalities across the various infectious disease topics included in this overview of reviews. CONCLUSION: We identified many reviews that provide evidence of various types of health inequalities in different infectious diseases, vaccination, and antimicrobial resistance. We also highlight areas where reviews may be lacking. The commonalities in the associations and their directions suggest it might be worth targeting interventions for some high risk-groups that may have benefits across multiple infectious disease outcomes rather than operating purely in infectious disease siloes.

Obesity Stigma: Causes, Consequences, and Potential Solutions.

PURPOSE OF REVIEW: This review aims to examine (i) the aetiology of obesity; (ii) how and why a perception of personal responsibility for obesity so dominantly frames this condition and how this mindset leads to stigma; (iii) the consequences of obesity stigma for people living with obesity, and for the public support for interventions to prevent and manage this condition; and (iv) potential strategies to diminish our focus on personal responsibility for the development of obesity, to enable a reduction of obesity stigma, and to move towards effective interventions to prevent and manage obesity within the population. RECENT FINDINGS: We summarise literature which shows that obesity stems from a complex interplay of genetic and environment factors most of which are outside an individual's control. Despite this, evidence of obesity stigmatisation remains abundant throughout areas of media, entertainment, social media and the internet, advertising, news outlets, and the political and public health landscape. This has damaging consequences including psychological, physical, and socioeconomic harm. Obesity stigma does not prevent obesity. A combined, concerted, and sustained effort from multiple stakeholders and key decision-makers within society is required to dispel myths around personal responsibility for body weight, and to foster more empathy for people living in larger bodies. This also sets the scene for more effective policies and interventions, targeting the social and environmental drivers of health, to ultimately improve population health.

The prevalence and socio-demographic associations of household food insecurity in seven slum sites across Nigeria, Kenya, Pakistan, and Bangladesh. A cross-sectional study.

Although the proportion of people living in slums is increasing in low- and middle-income countries and food insecurity is considered a severe hazard for health, there is little research on this topic. This study investigated and compared the prevalence and socio-demographic associations of household food insecurity in seven slum settings across Nigeria, Kenya, Pakistan, and Bangladesh. Data were taken from a cross-sectional, household-based, spatially referenced survey conducted between December 2018 and June 2020. Household characteristics and the extent and distribution of food insecurity across sites was established using descriptive statistics. Multivariable logistic regression of data in a pooled model including all slums (adjusting for slum site) and site-specific analyses were conducted. In total, a sample of 6,111 households were included. Forty-one per cent (2,671) of all households reported food insecurity, with varying levels between the different slums (9-69%). Household head working status and national wealth quintiles were consistently found to be associated with household food security in the pooled analysis (OR: 0·82; CI: 0·69-0·98 & OR: 0·65; CI: 0·57-0·75) and in the individual sites. Households which owned agricultural land (OR: 0·80; CI: 0·69-0·94) were less likely to report food insecurity. The association of the household head's migration status with food insecurity varied considerably between sites. We found a high prevalence of household food insecurity which varied across slum sites and household characteristics. Food security in slum settings needs context-specific interventions and further causal clarification.

'Choice should be made through educated decisions not regressive dictates': discursive framings of a proposed 'sugar tax' in Bermuda: analysis of submissions to a government consultation.

BACKGROUND: Several governments have introduced taxes on products with high sugar content as part of their obesity prevention strategies. Bermuda is the first jurisdiction to apply such measures in the Caribbean - a region of small island developing states and territories with high obesity prevalence and substantial reliance on imported food products. This study examines how commercial and health actors framed the proposed introduction of a 75% import tariff on high-sugar products, based on written submissions to the Bermudan government. METHODS: Eleven submissions containing written comments were analysed with reference to their framing of the proposed import tariff, the 'problem' of obesity, and the relationship between the two (including alternative policy approaches for tackling obesity). RESULTS: Key emergent frames were complexity, partnership, products, personal responsibility, affordability and evidence. Respondents favoured different framings, depending on whether they supported or opposed the proposed import duty. Commercial actors were universally opposed, presenting obesity as a 'complex' problem that would be better addressed through government-industry partnerships (a framing particularly favoured by international and regional business associations). Increased product range and an emphasis on personal responsibility were also positioned as policy alternatives. Health actors expressed partial support for the proposed sugar tax, although this was tempered by a perceived lack of evidence where the proposal differed from sugar taxes introduced elsewhere. Like commercial respondents, health actors framed obesity as a 'complex' problem and emphasised the need for other measures, including efforts to address the affordability of fruits and vegetables. CONCLUSION: In responding to a proposed 'sugar tax' in Bermuda, commercial actors opposed the proposal and stated a clear preference for 'partnership' approaches to tackling obesity. Commercial responses were dominated by local businesses (with only two responses received from international or regional business associations), perhaps reflecting Bermuda's reliance on tourism and hospitality and the specificity of the proposed intervention (that is, an import tariff rather than an excise tax). The much smaller number of responses from health actors suggests limited civil society capacity. Nevertheless, the Bermudan government successfully introduced a 75% tariff on high-sugar imports, demonstrating the potential for policy innovation to address obesity in small-island jurisdictions.

Type, density, and healthiness of food-outlets in a university foodscape: a geographical mapping and characterisation of food resources in a Ghanaian university campus.

INTRODUCTION: Food environments are viewed as the interface where individuals interact with the wider food system to procure and/or consume food. Institutional food environment characteristics have been associated with health outcomes including obesity and nutrition-related non-communicable diseases (NR-NCDs) in studies from high-income countries. The objectives of this study were (1) to map and characterise the food-outlets within a Ghanaian university campus; and (2) to assess the healthiness of the food outlets. METHODS: Data collection was undertaken based on geospatial open-source technologies and the collaborative mapping platform OpenStreetMap using a systematic approach involving three phases: remote mapping, ground-truthing, and food-outlet survey. Spatial analyses were performed using Quantum Geographical Information System (QGIS) and comprised kernel density, buffer, and average nearest neighbour analyses to assess outlet distribution, density, and proximity. A classification system was developed to assess the healthiness of food-outlets within the University foodscape. RESULTS: Food-outlets were unevenly distributed over the University foodscape, with many outlets clustered closer to student residencies. Informal food-outlets were the most frequent food-outlet type. Compared to NCD-healthy food-outlets, NCD-unhealthy food-outlets dominated the foodscape (50.7% vs 39.9%) with 9.4% being NCD-intermediate, suggesting a less-healthy university foodscape. More NCD-unhealthy food outlets than NCD-healthy food outlets clustered around student residences. This difference was statistically significant for food outlets within a 100-m buffer (p < 0.001) of student residence and those within 100 and 500 m from departmental buildings/lecture halls (at 5% level of significance). CONCLUSION: Further action, including research to ascertain how the features of the University's food environment have or are influencing students' dietary behaviours are needed to inform interventions aimed at creating healthier foodscapes in the study University and other campuses and to lead the way towards the creation of healthy food environments at the home, work, and community levels.

Cardiovascular disease risk profile and management among people 40 years of age and above in Bo, Sierra Leone: A cross-sectional study.

INTRODUCTION: Access to care for cardiovascular disease risk factors (CVDRFs) in low- and middle-income countries is limited. We aimed to describe the need and access to care for people with CVDRF and the preparedness of the health system to treat these in Bo, Sierra Leone. METHODS: Data from a 2018 household survey conducted in Bo, Sierra Leone, was analysed. Demographic, anthropometric and clinical data on CVDRF (hypertension, diabetes mellitus or dyslipidaemia) from randomly sampled individuals 40 years of age and above were collected. Future risk of CVD was calculated using the World Health Organisation-International Society of Hypertension (WHO-ISH) calculator with high risk defined as >20% risk over 10 years. Requirement for treatment was based on WHO package of essential non-communicable (PEN) disease guidelines (which use a risk-based approach) or requiring treatment for individual CVDRF; whether participants were on treatment was used to determine whether care needs were met. Multivariable regression was used to test associations between individual characteristics and outcomes. Data from the most recent WHO Service Availability and Readiness Assessment (SARA) were used to create a score reflecting health system preparedness to treat CVDRF, and compared to that for HIV. RESULTS: 2071 individual participants were included. Most participants (n = 1715 [94.0%]) had low CVD risk; 423 (20.6%) and 431 (52.3%) required treatment based upon WHO PEN guidelines or individual CVDRF, respectively. Sixty-eight (15.8%) had met-need for treatment determined by WHO guidelines, whilst 84 (19.3%) for individual CVDRF. Living in urban areas, having education, being older, single/widowed/divorced, or wealthy were independently associated with met need. Overall facility readiness scores for CVD/CVDRF care for all facilities in Bo district was 16.8%, compared to 41% for HIV. CONCLUSION: The number of people who require treatment for CVDRF in Sierra Leone is substantially lower based on WHO guidelines compared to CVDRF. CVDRF care needs are not met equitably, and facility readiness to provide care is low.

'We're meat, so we need to eat meat to be who we are': Understanding motivations that increase or reduce meat consumption among emerging adults in the University of Ghana food environment.

The increasing presence of meat products in the diets of sub-Saharan African (SSA) populations have consequences for human and planetary health in the subregion. But there are questions about whether emerging adults in SSA setting who are both important targets and potentially key drivers of dietary change are willing to modify their diets for health and ecological benefits. This study used focus group discussions and best friend dyad interviews with 46 university students. Verbatim transcripts were analysed thematically using NVivo-12. Various motivations to increase or reduce meat consumption are highlighted by the results, some of which participants deemed more relevant than others. Health concerns; animal welfare; and environmental sustainability were not important to this age group, and they did not consider changing their behaviour based on these drivers. Body weight/shape, meat as identity, pleasure, and joy; and meat-eating as part of socialisation were frequent drivers of increased meat consumption; religion/cultural practices were frequent drivers of limited consumption.

"We think about the quantity more": factors influencing emerging adults' food outlet choice in a university food environment, a qualitative enquiry.

BACKGROUND: In recent decades, the food environment has seen rapid transformation globally, altering food availability and access along with how people interact with the food environment and make food-related choice. OBJECTIVES & METHOD: This explorative study aimed to identify the factors that shape the decision-making process for food outlet choices among emerging adults in a Ghanaian University food environment. The study uses focus group discussions in combination with novel dyadic interviews with best friend pairs. Verbatim transcripts were analysed thematically using NVivo 12. RESULTS: Drawing on socio-ecological model (SEM) of behaviour, the study used testimony from 46 participants aged 18-25, 47% female, including individuals from major ethnicities and religions in Ghana, and identified three interwoven levels of influence shaping emerging adults' choices of food outlet. The main factors influencing food outlet choice were identified as food prices, spatial accessibility, budget, and food quantity/satiety with additional factors including hygiene, variety of foods, food quality and taste preferences as well as societal factors such as ambience and peer influence. CONCLUSION: Multi-component approaches that combine structural level interventions in food retailing along with individual level components may be effective at changing emerging adult consumption behaviour in SSA, although this needs to be studied.

Factors associated with accessing and utilisation of healthcare and provision of health services for residents of slums in low and middle-income countries: a scoping review of recent literature.

OBJECTIVE: To identify factors associated with accessing and utilisation of healthcare and provision of health services in slums. DESIGN: A scoping review incorporating a conceptual framework for configuring reported factors. DATA SOURCES: MEDLINE, Embase, CINAHL, Web of Science and the Cochrane Library were searched from their inception to December 2021 using slum-related terms. ELIGIBILITY CRITERIA: Empirical studies of all designs reporting relevant factors in slums in low and middle-income countries. DATA EXTRACTION AND SYNTHESIS: Studies were categorised and data were charted according to a preliminary conceptual framework refined by emerging findings. Results were tabulated and narratively summarised. RESULTS: Of the 15 469 records retrieved from all years, 4368 records dated between 2016 and 2021 were screened by two independent reviewers and 111 studies were included. The majority (63 studies, 57%) were conducted in Asia, predominantly in India. In total, 104 studies examined healthcare access and utilisation from slum residents' perspective while only 10 studies explored provision of health services from providers/planners' perspective (three studies included both). A multitude of factors are associated with accessing, using and providing healthcare in slums, including recent migration to slums; knowledge, perception and past experience of illness, healthcare needs and health services; financial constraint and competing priorities between health and making a living; lacking social support; unfavourable physical environment and locality; sociocultural expectations and stigma; lack of official recognition; and existing problems in the health system. CONCLUSION: The scoping review identified a significant body of recent literature reporting factors associated with accessing, utilisation and provision of healthcare services in slums. We classified the diverse factors under seven broad categories. The findings can inform a holistic approach to improving health services in slums by tackling barriers at different levels, taking into account local context and geospatial features of individual slums.
