Background: Cervical cancer is the most prevalent gynaecologic cancer in Nigeria. Despite being largely preventable through screening, cervical cancer is the second leading cause of cancer morbidity and mortality in Nigeria. To reduce the burden of cervical cancer in Nigeria, female health workers (FHWs) are expected to play an influential role in leading screening uptake and promoting access to cervical cancer education and screening.Aim: The aim of this systematic review is to assess the factors influencing cervical cancer screening (CCS) practice among FHWs in Nigeria.Methods: We conducted a systematic literature search across six (6) electronic databases namely MEDLINE, Embase, Scopus, African Index Medicus, CINAHL, and Web of Science between May 2020 and October 2020. Reference list and grey literature search were conducted to complement database search. Four reviewers screened 3171 citations against the inclusion criteria and critically appraised the quality of eligible studies. Narrative synthesis was used in summarising data from included studies.Results: Overall, 15 studies met the inclusion criteria and were all quantitative cross‐sectional studies. Included studies sampled a total of 3392 FHWs in Nigeria. FHWs had a high level of knowledge and positive attitude towards CCS. However, CCS uptake was poor. Predominant barriers to CCS uptake were the cost of screening, fear of positive results, lack of test awareness, reluctance to screen, low‐risk perception, and lack of time. In contrast, being married, increasing age, awareness of screening methods, and physician recommendation were the most documented facilitators.Conclusion: This study revealed that a complex interplay of socioeconomic, structural, and individual factors influences CCS among FHWs in Nigeria. Therefore, implementing holistic interventions targeting both health system factors such as cost of screening and infrastructure and individual factors such as low‐risk perception and fear of positive result affecting FHWs in Nigeria is critical to reducing the burden of cervical cancer.

Background: Minority ethnic groups are a fast-growing population in many high-income countries, partly due to the increasing population of immigrants and second-generation migrants. The dietary practices of some of these minority ethnic groups might make them to be disproportionately affected by obesity and increase their risks of developing non-communicable diseases. Population-specific interventions and strategies are vital to addressing poor nutritional practices among this population. Thus, this study systematically reviewed the perceptions of dietary intake amongst Black, Asian and other minority ethnic groups in high-income countries. Methods: This systematic review was conducted in line with the guidelines of the Joanna Briggs Institute (JBI) methodology for systematic reviews, using a meta-aggregative design. This systematic review identified and synthesised qualitative literature on the perceptions of dietary intake amongst BlackAsian and other minority ethnic groups in high-income countries. An extensive and comprehensive database search was conducted between January 2000 – May 2022 and included twenty (20) studies that met the eligibility criteria from six countries. The included studies were assessed for quality using the JBI qualitative assessment and review instrument. The JBI data extraction tools were used to retrieve relevant data from included articles, and the data were thematically analysed. Results: We identified eight major themes across this database: (1) “Social and Cultural Factors,” (2) “Availability and Accessibility,” (3) “Family and Community Influences,” (4) “Food Preferences”, (5) “Home Country Food Versus Host Country Food” (6) “Dietary Acculturation” (7) “Health and Healthy Eating” (8) “Perception of Nutritional Information.” Conclusion: Overall, Black, Asian, and other minority ethnic groups individuals were found to be aware of the effects of unhealthy eating on their health, and some of them have nutritional knowledge, but social and cultural factors, including structural factors, were deterrents to their healthy eating behaviours. An important finding from this review is that some participants believed that nutritional information, based on bio-medical science, was intended for only White population groups and that it was antagonistic to their cultural and community well-being.

Rising rates of childhood obesity have become a pressing issue in public health, threatening both the mental and physical well-being of children. Attempts to address this problem are multifaceted, and in England include the National Child Measurement Programme (NCMP) which assesses weight status in English primary school children in reception class (aged 4–5) and in year 6 (aged 10–11), with results being sent out to parents. However the effectiveness and impact of this routine parental feedback has yet to be fully understood. This paper reports one component of a mixed methods study undertaken in North East England, examining the impact of the feedback letters on parents’ understanding and feelings about their child’s weight status and whether or not this seemed likely to lead to behaviour change. One-to-one semi-structured interviews (n = 16) were conducted with a sample of parents/guardians after they had received their child’s weight results letter. Eight parents/guardians were sub-sampled from the group whose child had been indicated to be overweight or obese and eight were from the group whose child had been indicated to be of ideal weight status. Interviews were conducted until data saturation was reached for both groups. The reactions of parents/guardians whose children were identified as being overweight followed a sequence of behaviours ranging from shock, disgust with the programme, through denial and self-blame to acceptance, worry and intention to seek help. On the other hand, the reaction of parents/guardians whose children were identified as being ideal weight ranged from relief, pleasure and happiness through affirmation and self-congratulation to ‘othering’. Whilst overweight and obesity is often portrayed as a medical condition, parents/guardians see it as deeply rooted in their social lives and not in health terms. Parents believe that the causes of overeating and lack of exercise relate closely to the obesogenic environment, particularly the complex social and cultural milieu and time pressures within which this sample of people live. Associating this problem in feedback letters with dangerous diseases like cancer, and advising parents to visit GPs to resolve child weight issues was perceived as inappropriate by the parents, and caused controversy and anger. Given the likelihood that the NCMP will continue as a monitoring device, it is evident that the management of the process needs to be reviewed, with particular attention being paid to the feedback process. Local health authorities will need to manage parental expectations and ensure linkage with appropriately commissioned remedial weight management interventions.

Objectives: Low and Middle-Income Countries are experiencing a fast-paced epidemiological rise in clusters of non-communicable diseases such as diabetes and cardiovascular disease, forming an imminent rise in multimorbidity. However, preventing multimorbidity has received little attention in LMICs, especially in Sub-Saharan African Countries. Methods: Narrative review which scoped the most recent evidence in LMICs about multimorbidity determinants and appropriated them for potential multimorbidity prevention strategies. Results: MMD in LMICs is affected by several determinants including increased age, female sex, environment, lower socio-economic status, obesity, and lifestyle behaviours, especially poor nutrition, and physical inactivity. Multimorbidity public health interventions in LMICs, especially in Sub-Saharan Africa are currently impeded by local and regional economic disparity, underdeveloped healthcare systems, and concurrent prevalence of communicable and non-communicable diseases. However, lifestyle interventions that are targeted towards preventing highly prevalent multimorbidity clusters, especially hypertension, diabetes, and cardiovascular disease, can provide early prevention of multimorbidity, especially within Sub-Saharan African countries with emerging economies and socio-economic disparity. Conclusion: Future public health initiatives should consider targeted lifestyle interventions and appropriate policies and guidelines in preventing multimorbidity in LMICs.

Background: Communities with diverse ethnicity in high-income countries are disproportionately affected by poor diet-related health outcomes. In England, the United Kingdom’s government’s healthy eating dietary resources are not well accepted and are underutilised among this population. Thus, this study explored perceptions, beliefs, knowledge, and practices around dietary intake among communities with African and South Asian ethnicity residing in Medway, England.Methods: This qualitative study generated data from 18 adults aged 18 and above using a semi-structured interview guide. These participants were sampled using purposive and convenience sampling strategies. All the interviews were conducted in English over the telephone, and responses were thematically analysed.Results: Six overarching themes were generated from the interview transcripts: eating patterns, social and cultural factors, food preferences and routines, accessibility and availability, health and healthy eating, and perceptions about the United Kingdom government’s healthy eating resources.Conclusion: The results of this study indicate that strategies to improve access to healthy foods are required to improve healthy dietary practices among the study population. Such strategies could help address this group’s structural and individual barriers to healthy dietary practices. In addition, developing a culturally responsive eating guide could also enhance the acceptability and utilisation of such resources among communities with ethnic diversity in England.
