This study’s aim was to test associations between nutrition knowledge and obesity-related attitudes and physical activity (PA) among 3000 18–35-year-old men and women from Kenya, South Africa (SA), and the United Kingdom (UK).Methods: A cross-sectional online survey was conducted in April 2022. To estimate nutrition knowledge, dietary recommendation knowledge score was computed using the standard General Nutrition Knowledge questionnaire. Obesity-related attitudes were from the British Social Attitudes Survey. Self-reported days of vigorous and moderate PAs and walking were used. Ordinal logistic regression was employed to test all associations, while adjusting for age group, gender and a household asset score. Using simple mediation, testing was also done to ascertain whether obesity-related attitudes mediated associations between nutrition knowledge and PA. Results: Consistently, better nutrition knowledge was associated with disagreeing that ‘There is no reason to worry about obesity’ (ORs ≥ 1.09), but lower odds of being against ‘Providing free weight management courses’ and ‘Creating/improving cycle paths and pavements to encourage PA’ (ORs ≤ 0.90). Better nutrition knowledge was also associated with higher vigorous PA in SA (OR = 1.09), and moderate PA (OR = 1.04) and walking (OR = 1.12) in the UK. In the combined sample, associations of nutrition knowledge with vigorous PA were fully mediated by believing that ‘Obesity results from not exercising enough’ (11.1% mediated). Likewise, associations of nutrition knowledge with moderate PA were fully mediated by attitude towards ‘Creating or improving cycle paths and pavements to encourage PA’ in the UK (38.9% mediated).Conclusions: Nutrition knowledge is associated with obesity-related attitudes and PA among young adults, but some relationships are country-specific. Interventions based on findings from high-income countries should be evaluated before being implemented in low-resource settings.

Purpose– This study aims to ascertain the personal characteristics of a group of successful academic entrepreneurs in a South African university enterprise and the prevalent barriers and enablers to their entrepreneurial endeavour. Design/methodology/approach– The authors used a Delphi process to identify and rank the characteristics, enablers, barriers and behaviours of entrepreneurial academics, with a Nominal Group Technique applied to establish challenges they encounter managing their enterprise and to propose solutions. Findings– Perseverance, resilience and innovation are critical personal characteristics, while collaborative networks, efficient research infrastructure and established research competence are essential for success. The university’s support for entrepreneurship is a significant enabler, with unnecessary bureaucracy and poor Purpose– This study aims to ascertain the personal characteristics of a group of successful academic entrepreneurs in a South African university enterprise and the prevalent barriers and enablers to their entrepreneurial endeavour.

The university’s support for entrepreneurship is a significant enabler, with unnecessary bureaucracy and poor access to project and general enterprise funding an impediment. Successful academic entrepreneurs have strong leadership, and effective management and communication skills. Research limitations/implications– The main limitation is the small study participant group drawn from a single university enterprise, which complicates general disability. The study supported the use of Krueger’s (2009) entrepreneurial intentions model for low- and middle-income country (LMIC) academic entrepreneur investigation but proposed the inclusion of mitigators to entrepreneurial activation to recognise contextual deficiencies and challenges. Practical implications– Skills-deficient LMIC universities should extensively and directly support their entrepreneurial academics to overcome their contextual deficiencies and challenging environment. Originality/value– This study contributes to addressing the paucity of academic entrepreneur research in LMIC contexts by identifying LMIC-specific factors that inhibit the entrepreneur’s movement from entrepreneurial intention to entrepreneurial action.
Food insecurity and coping strategies associate with higher risk of anxiety and depression among South African households with children

Objective: To investigate food insecurity and related coping strategies, and their associations with the risk of anxiety and depression, among South African households with children. Design: Nationally representative cross-sectional study. Tools for assessing food insecurity, coping strategies, risk of anxiety and depression were assessed from the Community Childhood Hunger Identification Project, Coping Strategies Index, Generalised Anxiety Disorder-7 and Patient Health Questionnaire-9, respectively. We used ordered logistic regression to test associations of food insecurity and coping strategies with the risk of anxiety and depression. Moderating effects of each coping strategy were tested in the associations of food insecurity with anxiety and depression. Setting: South Africa, post COVID-19 restrictions, May–June 2022. Participants: 1,774 adults, weighted to 20,955,234 households. Results: Food insecurity prevalence was 23·7 % among households with children. All coping strategies were used to some extent, but relying on less preferred and less expensive foods was the most used strategy (85·5 % of food-insecure households). Moving to a higher level of food insecurity was associated with >1·6 greater odds of being in a higher risk of anxiety and depression. Sending a household member to beg for food was the strongest associated factor (OR = 1·7, P < 0·001). All coping strategies partly moderated (lessened) the associations of food insecurity with a higher risk of anxiety and depression. Conclusions: Food insecurity among households with children was high following the COVID-19 pandemic. Collaborative efforts between government, private sector and civil society to eradicate food insecurity should prioritise poorer households with children, as these populations are the most vulnerable.
