    “Be like Sweden” (?): Swedish COVID-19 strategy in mainstream and far-right US media

    by Mathilda Åkerlund, Jennifer Hollowell, Ralph Schroeder

    By means of a longitudinal systematic content analysis across six mainstream US news and six US far-right media outlets, we illustrate in this paper how the Swedish COVID-19 approach was refracted through ideologically diverse media outlets in the US. In doing so, we show how the same events can be interpreted through quite different ideological lenses and misconstrued for political purposes. We show how Sweden was championed as a beacon of limited state interference to criticise the US left and government’s pandemic approach; an interesting reversal of how Sweden is usually seen by the US (far) right. We discuss the implications of these findings.

    ‘Children awaken by playing’: a qualitative exploration of caregivers’ norms, beliefs and practices related to young children’s learning and early childhood development in rural Burkina Faso

    by Mari Dumbaugh, Mireille Belem, Sylvain Kousse, Patricia Ouoba, Adama Sankoudouma, Achille Mignondo Tchibozo, Pasco Fearon, Jennifer Hollowell, Z Hill

    Introduction Evidence suggests that responsive caregiving and early learning activities positively impact developmental outcomes, with positive effects throughout the life course. Early childhood development interventions should align with local values, beliefs and resources but there has been little research of caregiver beliefs and perspectives on development and learning, especially in sub-Saharan Africa. This qualitative study explored norms, beliefs, practices and aspirations around child development of caregivers of young children in rural Burkina Faso. Methods We conducted 32 in-depth interviews with mothers and fathers of young children and 24 focus group discussions with mothers, fathers and grandmothers, which included trying behaviours and reporting on experiences. The research informed the development of Scaling Up Nurturing Care, a Radio Intervention to Stimulate Early Childhood Development (SUNRISE), an early child development radio intervention. Results Caregivers described a process of ‘awakening’, through which children become aware of themselves and the world around them.Perceptions of the timing of awakening varied, but the ability to learn was thought to increase as children became older and more awake. Consequently, talking and playing with babies and younger children were perceived to have little developmental impact. Caregivers said children’s interactions with them, alongside God-given intelligence, was believed to impact later behaviour and development. Caregivers felt their role in helping their children achieve later in life was to pay for education, save money, provide advice and be good role models. Interaction and learning activities were not specifically mentioned. Caregivers who trialled interaction and learning activities reported positive experiences for themselves and their child, but interactions were often caregiver led and directive and play was often physical. Key barriers to carrying out the behaviours were poverty and a lack of time. Conclusions Exploring early childhood beliefs and practices can reveal important sociocultural beliefs which, if incorporated into programme planning and implementation, could help achieve more impactful, acceptable and equitable programmes.

    Estimating the effect of moving meat-free products to the meat aisle on sales of meat and meat-free products: A non-randomised controlled intervention study in a large UK supermarket chain

    by Carmen Piernas, Brian Cook, Richard Stevens, Cristina Stewart, Jennifer Hollowell, Peter Scarborough, Susan A. Jebb

    Background: Reducing meat consumption could bring health and environmental benefits, but there is little research to date on effective interventions to achieve this. A non-randomised controlled intervention study was used to evaluate whether prominent positioning of meat-free products in the meat aisle was associated with a change in weekly mean sales of meat and meat-free products. Methods and findings: Weekly sales data were obtained from 108 stores: 20 intervention stores that moved a selection of 26 meat-free products into a newly created meat-free bay within the meat aisle and 88 matched control stores. The primary outcome analysis used a hierarchical negative binomial model to compare changes in weekly sales (units) of meat products sold in intervention versus control stores during the main intervention period (Phase I: February 2019 to April 2019). Interrupted time series analysis was also used to evaluate the effects of the Phase I intervention. Moreover, 8 of the 20 stores enhanced the intervention from August 2019 onwards (Phase II intervention) by adding a second bay of meat-free products into the meat aisle, which was evaluated following the same analytical methods. During the Phase I intervention, sales of meat products (units/store/week) decreased in intervention (approximately −6%) and control stores (−5%) without significant differences (incidence rate ratio [IRR] 1.01 [95% CI 0.95–1.07]. Sales of meat-free products increased significantly more in the intervention (+31%) compared to the control stores (+6%; IRR 1.43 [95% CI 1.30–1.57]), mostly due to increased sales of meat-free burgers, mince, and sausages. Consistent results were observed in interrupted time series analyses where the effect of the Phase II intervention was significant in intervention versus control stores. Conclusions: Prominent positioning of meat-free products into the meat aisle in a supermarket was not effective in reducing sales of meat products, but successfully increased sales of meat-free alternatives in the longer term. A preregistered protocol (https://osf.io/qmz3a/) was completed and fully available before data analysis.

    Ethnic differences in singleton preterm birth in England and Wales, 2006‐12: Analysis of national routinely collected data

    by Yangmei Li, Maria A. Quigley, Alison Macfarlane, Hiranthi Jayaweera, Jennifer J. Kurinczuk, Jennifer Hollowell

    Background: Data recorded at birth and death registration in England and Wales have been routinely linked with data recorded at birth notification since 2006. These provide scope for detailed analyses on ethnic differences in preterm birth (PTB).Objectives: We aimed to investigate ethnic differences in PTB and degree of prematurity in England and Wales, taking into account maternal sociodemographic characteristics and to further explore the contribution of mother's country of birth to these ethnic differences in PTB.Methods: We analysed PTB and degree of prematurity by ethnic group, using routinely collected and linked data for all singleton live births in England and Wales, 2006‐2012. Logistic regression was used to adjust for mother's age, marital status/registration type, area deprivation and mother's country of birth.Results: In the 4 634 932 births analysed, all minority ethnic groups except ‘Other White’ had significantly higher odds of PTB compared with White British babies (ORs between 1.04‐1.25); highest odds were in Black Caribbean, Indian, Bangladeshi and Pakistani groups. Ethnic differences in PTB tended to be greater at earlier gestational ages. In all ethnic groups, odds of PTB were lower for babies whose mothers were born outside the UK.Conclusions: In England and Wales, Black Caribbean, Indian, Bangladeshi, Pakistani and Black African babies all have significantly increased odds of being born preterm compared with White British babies. Bangladeshis apart, these groups are particularly at risk of extremely PTB. In all ethnic groups, the odds of PTB are lower for babies whose mothers were born outside the UK. These ethnic differences do not appear to be wholly explained by area deprivation or other sociodemographic characteristics.

    Joint contribution of socioeconomic circumstances and ethnic group to variations in preterm birth, neonatal mortality and infant mortality in England and Wales: a population-based retrospective cohort study using routine data from 2006 to 2012

    by Charles Opondo, Ron Gray, Jennifer Hollowell, Yangmei Li, Jennifer J Kurinczuk, Maria A Quigley

    Objectives This study aimed to describe the variation in risks of adverse birth outcomes across ethnic groups and socioeconomic circumstances, and to explore the evidence of mediation by socioeconomic circumstances of the effect of ethnicity on birth outcomes. Setting England and Wales. Participants The data came from the 4.6 million singleton live births between 2006 and 2012. Exposure The main exposure was ethnic group. Socioeconomic circumstances, the hypothesised mediator, were measured using the Index of Multiple Deprivation (IMD), an area-level measure of deprivation, based on the mother’s place of residence. Primary and secondary outcome measures The primary outcomes were birth outcomes, namely: neonatal death, infant death and preterm birth. We estimated the slope and relative indices of inequality to describe differences in birth outcomes across IMD, and the proportion of the variance in birth outcomes across ethnic groups attributable to IMD. We investigated mediation by IMD on birth outcomes across ethnic groups using structural equation modelling. Results Neonatal mortality, infant mortality and preterm birth risks were 2.1 per 1000, 3.2 per 1000 and 5.6%, respectively. Babies in the most deprived areas had 47%–129% greater risk of adverse birth outcomes than those in the least deprived areas. Minority ethnic babies had 48%–138% greater risk of adverse birth outcomes compared with white British babies. Up to a third of the variance in birth outcomes across ethnic groups was attributable to differences in IMD, and there was strong statistical evidence of an indirect effect through IMD in the effect of ethnicity on birth outcomes. Conclusion There is evidence that socioeconomic circumstances could be contributing to the differences in birth outcomes across ethnic groups.

    Ethnic and socioeconomic variation in cause-specific preterm infant mortality by gestational age at birth: national cohort study

    by Mary E Kroll, Jennifer J Kurinczuk, Jennifer Hollowell, Alison Macfarlane, Yangmei Li, Maria A Quigley

    Objective To describe ethnic and socioeconomic variation in cause-specific infant mortality of preterm babies by gestational age at birth. Design National birth cohort study. Setting England and Wales 2006–2012. Subjects Singleton live births at 24–36 completed weeks’ gestation (n=256 142). Outcome measures Adjusted rate ratios for death in infancy by cause (three groups), within categories of gestational age at birth (24–27, 28–31, 32–36 weeks), by baby’s ethnicity (nine groups) or area deprivation score (Index of Multiple Deprivation quintiles). Results Among 24–27 week births (5% of subjects; 47% of those who died in infancy), all minority ethnic groups had lower risk of immaturity-related death than White British, the lowest rate ratios being 0.63 (95% CI 0.49 to 0.80) for Black Caribbean, 0.74 (0.64 to 0.85) for Black African and 0.75 (0.60 to 0.94) for Indian. Among 32–36 week births, all minority groups had higher risk of death from congenital anomalies than White British, the highest rate ratios being 4.50 (3.78 to 5.37) for Pakistani, 2.89 (2.10 to 3.97) for Bangladeshi and 2.06 (1.59 to 2.68) for Black African; risks of death from congenital anomalies and combined rarer causes (infection, intrapartum conditions, SIDS and unclassified) increased with deprivation, the rate ratios comparing the most with the least deprived quintile being, respectively, 1.54 (1.22 to 1.93) and 2.05 (1.55 to 2.72). There was no evidence of socioeconomic variation in deaths from immaturity-related conditions. Conclusions Gestation-specific preterm infant mortality shows contrasting ethnic patterns of death from immaturity-related conditions in extremely-preterm babies, and congenital anomalies in moderate/late-preterm babies. Socioeconomic variation derives from congenital anomalies and rarer causes in moderate/late-preterm babies. Future research should examine biological origins of extremely preterm birth.

    Exploring women’s preferences for birth settings in England: A discrete choice experiment

    by Benjamin Rupert Fletcher, Rachel Rowe, Jennifer Hollowell, Miranda Scanlon, Lisa Hinton, Oliver Rivero-Arias

    To explore pregnant women’s preferences for birth setting in England. Labelled discrete choice experiment (DCE). Online survey. Pregnant women recruited through social media and an online panel. We developed a DCE to assess women’s preferences for four hypothetical birth settings based on seven attributes: reputation, continuity of care, distance from home, time to see a doctor, partner able to stay overnight, chance of straightforward birth and safety for baby. We used a mixed logit model, with setting modelled as an alternative-specific constant, and conducted a scenario analysis to evaluate the impact of changes in attribute levels on uptake of birth settings. Women’s preferences for birth setting. 257 pregnant women completed the DCE. All birth setting attributes, except ‘time to see doctor’, were significant in women’s choice (p<0.05). There was significant heterogeneity in preferences for some attributes. Changes to levels for ‘safety for the baby’ and ‘partner able to stay overnight’ were associated with larger changes from baseline uptake of birth setting. If the preferences identified were translated into the real-world context up to a third of those who reported planning birth in an obstetric unit might choose a midwifery unit assuming universal access to all settings, and knowledge of the differences between settings. We found that ‘safety for the baby’, ‘chance of a straightforward birth’ and ‘can the woman’s partner stay overnight following birth’ were particularly important in women’s preferences for hypothetical birth setting. If all birth settings were available to women and they were aware of the differences between them, it is likely that more low risk women who currently plan birth in OUs might choose a midwifery unit.

    ‘Grandmother, aren’t you going to sing for us?’ Current childcare practices and caregivers’ perceptions of and receptivity to early childhood development activities in rural Burkina Faso

    by Jennifer Hollowell, Mari Dumbaugh, Mireille Belem, Sylvain Kousse, Tessa Swigart, Chantal Korsaga, Pokiandi Solange Lankoande, Kokovi Hogban Lawson, Zelee Hill

    Introduction Effective stimulation and responsive caregiving during the first 2 years is crucial for children’s development. By age 3–4 years, over 40% of children in sub-Saharan Africa fail to meet basic cognitive or socioemotional milestones, but there are limited data on parenting and childcare practices. This study, conducted to inform the design of a mass media intervention, explored practices, perceptions, motivators and obstacles to childhood development-related practices among parents and caregivers of children aged 0–2 years in rural Burkina Faso. Methods We performed two rounds of six focus groups with 41 informants in two villages, using an adapted version of the Trials of Improved Practices methodology. These first explored beliefs and practices, then introduced participants to the principles and benefits of early childhood development (ECD) and provided illustrative examples of three practices (interactive ways of talking, playing and praising) to try with their children. One week later, further discussions explored participants’ experiences and reactions. Data were analysed inductively using thematic content analysis. Results Existing activities with young children were predominantly instructive with limited responsive interaction and stimulation. Participants were receptive to the practices introduced, noted positive changes in their children when they adopted these practices and found engagement with children personally rewarding. Conclusion Interactive, stimulating activities with young children did not appear to be widespread in the study area, but caregivers were receptive to information about the importance of early stimulation for children’s development. ECD messages should be tailored to the local sociocultural context and consider time limitations.

    Can health promotion videos ‘go viral’? A non-randomised, controlled, before-and-after pilot study to measure the spread and impact of local language mobile videos in Burkina Faso

    by Tessa Swigart, Jennifer Hollowell, Pieter Remes, Matthew Lavoie, Joanna Murray, Mireille Belem, Rita Lamoukri, Souleymane Salouka, Kethakie Lamahewa, Roy Head

    Background: Mobile phones present a new health communications opportunity but use of mobile videos warrants more exploration. Our study tested a new idea: to produce health promotion videos in languages for which films have never previously been produced to see if they were widely shared. Objective: To investigate whether the novelty of films in local languages focusing on health messages would be shared ‘virally’ among the target population. Methods: A non-randomised, controlled, before-and-after study was used to evaluate the reach and impact of the intervention. We gave short health promotion videos on memory cards to distributors in eight intervention villages. Ten control villages, where no video distribution took place were randomly selected. We conducted cluster-level difference-in-difference logistic regression to assess self-reported knowledge indicators. We calculated odds ratios for intervention relative to control at baseline and endline and p-values for the change in odds ratios. Results: Seven hundred and eight mothers were interviewed across all villages at baseline and 728 different mothers and 726 men were interviewed in the same villages a year later in October 2015. At endline, 32% of women and 44% of men in the intervention arm had ever seen a film on a mobile phone in Lobiri, compared to 1% of women and 2% of men in the control arm. There was a significant increase in the odds of knowing about giving Orasel to a child with diarrhoea in the intervention area relative to the control area. Awareness of the need to take a child with fever or symptoms of pneumonia to a health centre increased in the intervention area, but not significantly. Conclusions: Viral sharing of films on mobile phones has the potential to be an effective health promotion tool for communities whose languages are not served by existing mass media channels.
