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.

Many studies have focused on risky sexual behaviour among adolescents and young adults; however, literature on protective sexual practices among this age cohort is still evolving. Since young adults are disproportionately burdened by sexually transmissible infections, including HIV, understanding factors that influence protective sexual behaviour among the age group is crucial in developing age-appropriate interventions. Drawing from a cross-sectional survey conducted among adolescents and young adults in two Nigerian universities, we examined gender differences in protective sexual behaviours and the influence of family support and living with both parents on these behaviours. A total of 800 male and female university students in two Nigerian universities were recruited using stratified random sampling between February and April 2018. Analysis was, however, based on 599 participants aged between 15 and 24 . Adjusted and unadjusted multinomial logistic regression models were used to examine the influence of family support, and living with both parents on protective sexual behaviours at a 95% confidence interval. Findings show that the largest proportion of our participants engaged in protective sexual behaviours. We found no gender differences in protective sexual behaviours, including sexual abstinence, consistent condom use, and sexual fidelity. Family support and living with both parents were positively associated with protective sexual behaviours among adolescents and young adults. This study found that a majority of adolescents and young adults in Nigerian Universities engage in protective sexual behaviours. Adequate family support and living with both parents are positively associated with protective sexual behaviours. The study however revealed that about one-fifth of our participants engaged in high-risk sexual behaviour. This suggests a need for behavioural change interventions, provision of sexual health services and empowerment of students who receive inadequate family support.

The COVID-19 pandemic has aggravated pre-existing challenges associated with adolescents’ sexual and reproductive health and rights (SRHR). Evolving evidence suggest that it could adversely impact the progress made towards improving sexual and reproductive health outcomes among young people. The pandemic has stalled achievements in reducing adolescent pregnancy and child marriage by reinforcing contextual and structural determinants of these reproductive health outcomes, especially among girls. The pandemic has increased disruptions to schooling, decreased access to sexual and reproductive health services and compounded pre-existing socio-economic vulnerabilities. The consequences of neglecting adolescent sexual and reproductive health services over the past 2 years, to focus on COVID-19, continue to emerge. This commentary argues for targeted and responsive approaches to adolescent SRHR that tackle preventable consequences resulting from inequities faced by adolescents globally, particularly girls.

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.

Introduction: Sexual norms, real or perceived, shape young people’s sexual behaviour and may constitute one of the greatest challenges in HIV/STIs prevention among this population. This study used sexual script theory to explore how international students in Sydney, Australia – from traditional cultures of East Asian and sub-Saharan African countries – construct home backgrounds and Australian sexual norms and how this may shape their sexual practices during their studies in Australia. Methods: The study involved face-to-face and telephone semi-structured in-depth interviews. Data were provided by 20 international students who are enrolled in various universities in Sydney. Interviews were audio-recorded, transcribed, coded into NVivo and analysed using reflexive thematic analysis. Results: Identified patterns in the data showed three themes through which participants perceive sexual norms in Australia as distinctly different from their home country norms. First, participants stated that unlike their home country norms, sexual norms in Australia are permissive. Second, participants hold the view that compared to their home country norms, sex in Australia is largely casual as it is not always attached to love. Some participants revealed that this could shape their own sexual practices during their studies in Australia. Finally, participants noted that compared to their home countries’ norm of sex talk taboo, Australia has an open sexual communication norm; which they believe, enables young people in western societies to easily acquire sexual health information. Conclusions: Findings provide evidence to support a need for contextualized and effective sexual health services for international students that take account of perceptions around sexual norms and how they can be modified to ensure that sexual practices which these students may engage in, will be managed in a safe and responsible manner.

Background: Though women in sub-Saharan Africa have increased risk of intimate sexual violence, research on the association between sexual autonomy and intimate partner violence among this population has not received the requisite attention. Consequently, we investigated if sexual autonomy is a protective factor against intimate partner violence among women in sub-Saharan Africa. Methods: Secondary data analysis was conducted based on the Demographic and Health Surveys (DHSs) of 27 sub-Saharan African countries from 2008 to 2021. A total of 104,523 married or cohabitating women were included in the study. We applied a multilevel Poisson regression model with robust variance to identify associated factors. Variables with a p-value<0.2 in the bi-variable multilevel Poisson regression analysis were considered for the multivariable analysis. The Adjusted Prevalence Ratio (APR) with its 95% confidence interval (CI) was reported, and variables with a p-value <0.05 were included in the multivariable analysis. Results: The prevalence of intimate partner violence and sexual autonomy among women in SSA were 32.96% [95% CI: 32.68%, 33.25%] and 88.79% [95% CI: 88.59%, 88.97%], respectively. Women in Sierra Leone had the highest prevalence of IPV (52.71%) while Comoros had the lowest prevalence of IPV (8.09%). The prevalence of sexual autonomy was highest in Namibia (99.22%) and lowest in Mali (61.83%). The MOR value in the null model was 1.26. We found that women who had sexual autonomy are 1.28 times [APR = 1.28, 95% CI: 1.17, 1.40] more likely to experience IPV than women who had no sexual autonomy. Conclusion: This study has demonstrated that sexual autonomy is significantly associated with intimate partner violence, however, it does not necessarily act as a protective factor. The study suggests the need for more education on intimate partner violence targeting women’s partners. This can help secure the commitment of the perpetrators to rather become proponents of anti-intimate partner violence and further offer women the necessary support for them to attain their full fundamental rights in all spheres of life.
