Our study explored the impact of COVID-19 for African migrants in New South Wales, Australia, and their coping strategies. Methods We employed inductive, exploratory qualitative interpretive research de…
Experiences and challenges of African traditional medicine: Lessons from Covid-19 pandemic
Open AccessPolydor Ngoy Mutombo, Ossy Muganga Julius Kasilo et al.ARTICLEBMJ Global Health2023
Management of COVID-19 in Africa is challenging due to limited resources, including the high cost of vaccines, diagnostics, medical devices and routine pharmaceuticals. These challenges, in addition to wide acceptability, have resulted in increased use of herbal medicines based on African traditional medicines (ATMs) by patients in Africa. This is in spite of the often-significant gaps in evidence regarding these traditional medicines as to their…
Traditional, complementary and integrative healthcare: Global stakeholder perspective on WHO’s current and future strategy
Open AccessTido von Schoen-Angerer, Raj Kumar Manchanda et al.ARTICLEBMJ Global Health2023
As the ‘WHO Traditional Medicine Strategy: 2014–2023’ is entering its final phase, reflection is warranted on progress and the focus for a new strategy. We used WHO documentation to analyse progress across the objectives of the current strategy, adding the role of traditional, complementary and integrative healthcare (TCIH) to address specific diseases as a dimension absent in the current strategy. Our analysis concludes on five areas. First, TCI…

Providing healthcare to Ebola survivors: A qualitative exploratory investigation of healthcare providers’ views and experiences in Sierra Leone
Open AccessPeter Bai James, Jon Wardle et al.ARTICLEGlobal Public Health2020
Although the experiences of healthcare workers regarding caring for Ebola patients during the West African Ebola outbreak have been explored, little is known about healthcare workers' experiences in providing care to Ebola survivors. We employed a qualitative design to address this gap in the literature. Healthcare providers described the health complaints of Ebola survivors as similar to those of ordinary patients, but disproportionately frequen…
An assessment of Ebola-related stigma and its association with informal healthcare utilisation among Ebola survivors in Sierra Leone: A cross-sectional study
Open AccessPeter Bai James, Jon Wardle et al.ARTICLEBMC Public Health2020
Our findings suggest EVD-related stigma (internalised and enacted) is prevalent among EVD survivors since their return to their communities. Religiosity, perceived health status and region were identified as independent predictors of internalised stigma. Verbal abuse and healthcare neglect predict informal healthcare use. EVD survivor-centred and community-driven anti-stigma programs are needed to promote EVD survivors' recovery and community re-…

Attitudes towards lung cancer screening in socioeconomically deprived and heavy smoking communities: Informing screening communication
Open AccessSamantha L Quaife, Laura A V Marlow et al.ARTICLEHealth Expectations2017
BACKGROUND: While discussion continues over the future implementation of lung cancer screening, low participation from higher risk groups could limit the effectiveness of any national screening programme. OBJECTIVES: To compare smokers' beliefs about lung cancer screening with those of former and never smokers within a low socioeconomic status (SES) sample, to explore the views of lower SES smokers and ex-smokers in-depth, and to provide insights…
Ethnic minority women prefer strong recommendations to be screened for cancer
Open AccessLaura A V Marlow, Susanne F Meisel et al.ARTICLEBMC Public Health2017
A strong recommendation to participate in cancer screening appears to be important for ethnic minority women, particularly non-English speakers. Future research could explore how to best arrive at a consensus that respects patient autonomy while also accommodating those that would prefer to be guided by a trusted source
Cancer and heart attack survivors’ expectations of employment status: Results from the English Longitudinal Study of Ageing
Open AccessSaskia F A Duijts, Allard J van der Beek et al.ARTICLEBMC Public Health2017
When predicting future employment status in cancer survivors in the UK, general health is the most relevant factor to consider. While expectation of being at work did not show any significant influence in cancer survivors, in heart attack survivors, it should not be disregarded though, when developing interventions to affect their employment status. Future research should focus on more specific measures for expectation, and additional behavioural…
Impact of a decision aid about stratified ovarian cancer risk-management on women’s knowledge and intentions: A randomised online experimental survey study

The impact of body vigilance on help-seeking for cancer ‘alarm’ symptoms: A community-based survey
Open AccessKelly Winstanley, Cristina Renzi et al.ARTICLEBMC Public Health2016
Respondents who paid attention to their bodily changes were more likely to seek help for their symptoms. Although the use of a cross-sectional study design and the limited assessment of key variables preclude any firm conclusions, encouraging people to be body vigilant may contribute towards earlier cancer diagnosis. More needs to be understood about the impact this might have on cancer-related anxiety
A lack of information engagement among colorectal cancer screening non-attenders: Cross-sectional survey
Open AccessLindsay C Kobayashi, Jo Waller et al.ARTICLEBMC Public Health2016
Although 'The Facts' booklet is intended to support informed choices about CRC screening, the majority of unscreened individuals report that they have read none of it. The degree to which public engagement with the decision-making process about cancer screening is socially unequal must be better understood so that comprehensive and equitable public communication strategies can be developed
Quantitative evaluation of an information leaflet to increase prompt help-seeking for gynaecological cancer symptoms
Open AccessMelanie Morris, Claire Friedemann Smith et al.ARTICLEBMC Public Health2016
Increased symptom knowledge and lowered perceived barriers were related to increased prompt anticipated help-seeking. This occurred without an increase in anxiety. This intervention is effective in altering knowledge, beliefs and help-seeking intentions for gynaecological cancer symptoms, at least in the short-term, and should be trialled in primary care

Appetitive traits and relationships with BMI in adults: Development of the Adult Eating Behaviour Questionnaire
Open AccessClaudia Hunot-Alexander, Claudia Hunot et al.ARTICLEAppetite2016Cited by: 54References: 35
The Child Eating Behaviour Questionnaire (CEBQ) is a validated parent-report measure of appetitive traits associated with weight in childhood. There is currently no matched measure for use in adults. The aim of this study was to adapt the CEBQ into a self-report Adult Eating Behaviour Questionnaire (AEBQ) to explore whether the associations between appetitive traits and BMI observed in children are present in adults. Two adult samples were recrui…
The associations between objective numeracy and colorectal cancer screening knowledge, attitudes and defensive processing in a deprived community sample
Open AccessSamuel G Smith, Lindsay C Kobayashi et al.ARTICLEJournal of Health Psychology2016Cited by: 1References: 40
We examined associations between numeracy and sociocognitive factors associated with colorectal cancer screening uptake ( n = 964). Nearly half (45.7%) of the respondents incorrectly answered a numeracy question (low numeracy). Low numeracy respondents were less knowledgeable about colorectal cancer ( p < .001), less positive towards screening (emotional, p < .001 and practical, p = .001) and less likely to intend to participate in screening ( p …

The Influence of Partner’s Behavior on Health Behavior Change: The English Longitudinal Study of Ageing
Sarah E Jackson, Andrew Steptoe et al.ARTICLEJAMA Internal Medicine2015
IMPORTANCE: Couples are highly concordant for unhealthy behaviors, and a change in one partner's health behavior is often associated with a change in the other partner's behavior. However, no studies have explicitly compared the influence of having a partner who takes up healthy behavior (eg, quits smoking) with one whose behavior is consistently healthy (eg, never smokes). OBJECTIVE: To examine the influence of partner's behavior on making posit…
Attitudes and beliefs of non‐participants in a population‐based screening programme for colorectal cancer
Open AccessNicola J Hall, Nicola Hall et al.ARTICLEHealth Expectations2015
BACKGROUND: Uptake of colorectal cancer screening programmes needs to be improved or at least maintained in order to achieve projected reductions in mortality and morbidity. Understanding the origins of non-participation in screening is therefore important. OBJECTIVE: To explore the beliefs and experiences of individuals who had not responded either to their screening invitation or reminder. DESIGN: A qualitative study using in-depth interviews w…

Weekday and weekend patterns of objectively measured sitting, standing, and stepping in a sample of office-based workers: The active buildings study
Open AccessLee Smith, Mark Hamer et al.ARTICLEBMC Public Health2015
Office based-workers demonstrate high levels of sitting during both the working week and weekend. Interventions that target the working day and the evenings (weekday and weekend) to displace sitting with activity may offer most promise for reducing population levels of sedentary behaviour and increasing physical activity levels, in office-based workers residing in England
Hungry for an intervention? Adolescents’ ratings of acceptability of eating-related intervention strategies
Open AccessF Marijn Stok, Denise De Ridder et al.ARTICLEBMC Public Health2015
Adolescents preferred intervention strategies that promote healthy eating over strategies that discourage unhealthy eating. Level of intrusiveness affected acceptability ratings for the latter type of strategies only. Various individual and behavioral characteristics were associated with acceptability. These findings provide practical guidance for the selection of acceptable intervention strategies to improve adolescents' eating behavior

Fear of dentistry

Open AccessJon Wardle, Jane Wardle et al.ARTICLEJournal of Community & Applied…1993Cited by: 9References: 1
The comparatively lower prevalence of eating disorders among Asian and Afro‐Caribbean than Caucasian women in the UK has often been attributed to cultural differences in pressures for slimness. However, there have been no attempts to evaluate cultural differences in ideals for female physique directly among women in the at risk age groups. In the present study, cultural influences on body image were evaluated by comparing the body size ideals, bo…

Increased Salivary Cortisol Reliably Induced by a Protein-Rich Midday Meal
E Leigh Gibson, Stuart Checkley et al.ARTICLEPsychosomatic Medicine1999
OBJECTIVE: This study was conducted to determine whether an increase in salivary free cortisol would be reliably elicited by a midday meal, thus providing a convenient physiological challenge to the hypothalamic-pituitary-adrenal (HPA) axis, and whether this cortisol release depended on the protein content of the meal. METHOD: In healthy men, free cortisol was measured in saliva samples taken before and after two identical protein-rich midday mea…
Stress and Food Choice: A Laboratory Study
Georgina Oliver, Jon Wardle et al.ARTICLEPsychosomatic Medicine2000

Locus of control and health behaviour revisited: A multivariate analysis of young adults from 18 countries
Open AccessAndrew Steptoe, Jon Wardle et al.ARTICLEBritish Journal of Psychology2001Cited by: 20
The inconsistent and small associations between health locus of control and health behaviour found in previous studies may be due to the use of small samples, and an over‐reliance on correlations as measures of association. We assessed relationships between internal powerful others and chance health locus of control, health values, and ten health‐related behaviours (physical exercise, smoking, alcohol consumption, breakfast, tooth‐brushing, seat …
