This study compared the level of education and tests from multiple cognitive domains as proxies for cognitive reserve.

The participants were educationally, ethnically, and cognitively diverse older adults enrolled in a longitudinal aging study. We examined independent and interactive effects of education, baseline cognitive scores, and MRI measures of cortical gray matter change on longitudinal cognitive change.

Baseline episodic memory was related to cognitive decline independent of brain and demographic variables and moderated (weakened) the impact of gray matter change. Education moderated (strengthened) the gray matter change effect. Non-memory cognitive measures did not incrementally explain cognitive decline or moderate gray matter change effects.

Episodic memory showed strong construct validity as a measure of cognitive reserve. Education effects on cognitive decline were dependent upon the rate of atrophy, indicating education effectively measures cognitive reserve only when atrophy rate is low. Results indicate that episodic memory has clinical utility as a predictor of future cognitive decline and better represents the neural basis of cognitive reserve than other cognitive abilities or static proxies like education.

Studies in countries where assisted dying is legal show that bereaved people express concern over the potential for social disapproval and social stigma because of the manner of death. There are indications that voluntary assisted dying is judged as less acceptable if the deceased is younger. A vignette-based experiment was used to determine whether public stigma (i.e., negative emotional reactions and desired social distance) and expected grief symptoms are higher for conjugally bereaved people through voluntary assisted dying (vs. long-term illness), when the deceased is a young adult (vs. older adult).

A 2 × 2 randomized factorial design was conducted with 164 Australian adults (130 women, 34 men, Mage = 37.69 years). Each participant was randomized online to read one of four vignettes and completed measures of anger, fear, prosocial emotions, desire for social distance, and expectations of grief symptomatology.

A multivariate analysis of variance (MANOVA) was conducted. Death at a young age (28 years) was significantly associated with stronger negative emotional reactions of fear ($\eta _p^2 = 0.04$, P = 0.048) and anger ($\eta _p^2 = 0.06$, P = 0.010). There were no differences in outcomes associated with the mode of death, nor was there an interaction between mode of death and age group.

Concerns that voluntary assisted dying elicits public stigma appear unfounded. The fact that participants reported significantly higher anger and fear in response to bereaved people experiencing loss at a younger (vs. older) age, irrespective of cause of death, indicates that young people who lose their spouse might benefit from additional support.

To explore the perceptions of adolescents and their caregivers on drivers of diet and physical activity in rural India in the context of ongoing economic, social and nutrition transition.

A qualitative study comprising eight focus group discussions (FGD) on factors affecting eating and physical activity patterns, perceptions of health and decision-making on food preparation.

Villages approximately 40–60 km from the city of Pune in the state of Maharashtra, India.

Two FGD with adolescents aged 10–12 years (n 20), two with 15- to 17- year-olds (n 18) and four with their mothers (n 38).

Dietary behaviour and physical activity of adolescents were perceived to be influenced by individual and interpersonal factors including adolescent autonomy, parental influence and negotiations between adolescents and caregivers. The home food environment, street food availability, household food security and exposure to television and digital media were described as influencing behaviour. The lack of facilities and infrastructure was regarded as barriers to physical activity as were insufficient resources for public transport, safe routes for walking and need for cycles, particularly for girls. It was suggested that schools take a lead role in providing healthy foods and that governments invest in facilities for physical activity.

In this transitioning environment, that is representative of many parts of India and other Lower Middle Income Countries (LMIC), people perceive a need for interventions to improve adolescent diet and physical activity. Caregivers clearly felt that they had a stake in adolescent health, and so we would recommend the involvement of both adolescents and caregivers in intervention design.

To explore, from the perspectives of adolescents and caregivers, and using qualitative methods, influences on adolescent diet and physical activity in rural Gambia.

Six focus group discussions (FGD) with adolescents and caregivers were conducted. Thematic analysis was employed across the data set.

Rural region of The Gambia, West Africa.

Participants were selected using purposive sampling. Four FGD, conducted with forty adolescents, comprised: girls aged 10–12 years; boys aged 10–12 years; girls aged 15–17 years, boys aged 15–17 years. Twenty caregivers also participated in two FGD (mothers and fathers).

All participants expressed an understanding of the association between salt and hypertension, sugary foods and diabetes, and dental health. Adolescents and caregivers suggested that adolescent nutrition and health were shaped by economic, social and cultural factors and the local environment. Adolescent diet was thought to be influenced by: affordability, seasonality and the receipt of remittances; gender norms, including differences in opportunities afforded to girls, and mother-led decision-making; cultural ceremonies and school holidays. Adolescent physical activity included walking or cycling to school, playing football and farming. Participants felt adolescent engagement in physical activity was influenced by gender, seasonality, cultural ceremonies and, to some extent, the availability of digital media.

These novel insights into local understanding should be considered when formulating future interventions. Interventions need to address these interrelated factors, including misconceptions regarding diet and physical activity that may be harmful to health.

To describe the anthropometry, socioeconomic circumstances, diet and screen time usage of adolescents in India and Africa as context to a qualitative study of barriers to healthy eating and activity.

Cross-sectional survey, including measured height and weight and derived rates of stunting, low BMI, overweight and obesity. Parental schooling and employment status, household assets and amenities, and adolescents’ dietary diversity, intake of snack foods, mobile/smartphone ownership and TV/computer time were obtained via a questionnaire.

Four settings each in Africa (rural villages, West Kiang, The Gambia; low-income urban communities, Abidjan, Cote D’Ivoire; low/middle-class urban communities, Jimma, Ethiopia; low-income township, Johannesburg, South Africa) and India (rural villages, Dervan; semi-rural villages, Pune; city slums, Mumbai; low-middle/middle-class urban communities, Mysore).

Convenience samples (n 41–112 per site) of boys and girls, half aged 10–12 years and another half aged 15–17 years, were recruited for a qualitative study.

Both undernutrition (stunting and/or low BMI) and overweight/obesity were present in all settings. Rural settings had the most undernutrition, least overweight/obesity and greatest diet diversity. Urban Johannesburg (27 %) and Abidjan (16 %), and semi-rural Pune (16 %) had the most overweight/obesity. In all settings, adolescents reported low intakes of micronutrient-rich fruits and vegetables, and substantial intakes of salted snacks, cakes/biscuits, sweets and fizzy drinks. Smartphone ownership ranged from 5 % (West Kiang) to 69 % (Johannesburg), higher among older adolescents.

The ‘double burden of malnutrition’ is present in all TALENT settings. Greater urban transition is associated with less undernutrition, more overweight/obesity, less diet diversity and higher intakes of unhealthy/snack foods.

To explore influences on adolescent diet and physical activity, from the perspectives of adolescents and their caregivers, in Jimma, Ethiopia.

Qualitative design, using focus group discussions (FGD).

A low-income setting in Jimma, Ethiopia.

Five FGD with adolescents aged 10–12 years and 15–17 years (n 41) and three FGD with parents (n 22) were conducted.

Adolescents displayed a holistic understanding of health comprising physical, social and psychological well-being. Social and cultural factors were perceived to be the main drivers of adolescent diet and physical activity. All participants indicated that caregivers dictated adolescents’ diet, as families shared food from the same plate. Meals were primarily determined by caregivers, whose choices were driven by food affordability and accessibility. Older adolescents, particularly boys, had opportunities to make independent food choices outside of the home which were driven by taste and appearance, rather than nutritional value. Many felt that adolescent physical activity was heavily influenced by gender. Girls’ activities included domestic work and family responsibilities, whereas boys had more free time to participate in outdoor games. Girls’ safety was reported to be a concern to caregivers, who were fearful of permitting their daughters to share overcrowded outdoor spaces with strangers.

Adolescents and caregivers spoke a range of social, economic and cultural influences on adolescent diet and physical activity. Adolescents, parents and the wider community need to be involved in the development and delivery of effective interventions that will take into consideration these social, economic and cultural factors.

To explore, adolescents’ and caregivers’ perspectives, about shaping of diet and physical activity habits in rural Konkan, India.

Five focus group discussions (FGD) were conducted with adolescents and two with caregivers. Data were analysed using thematic analysis.

FGD were conducted in secondary schools located in remote rural villages in the Ratnagiri district, Konkan region, Maharashtra, India.

Forty-eight adolescents were recruited including twenty younger (10–12 years) and twenty-eight older (15–17 years) adolescents. Sixteen caregivers (all mothers) were also recruited.

Three themes emerged from discussion: (i) adolescents’ and caregivers’ perceptions of the barriers to healthy diet and physical activity, (ii) acceptance of the status quo and (iii) salience of social and economic transition. Adolescents’ basic dietary and physical activity needs were rarely met by the resources available and infrastructure of the villages. There were few opportunities for physical activity, other than performing household chores and walking long distances to school. Adolescents and their caregivers accepted these limitations and their inability to change them. Increased use of digital media and availability of junk foods marked the beginning of a social and economic transition.

FGD with adolescents and their caregivers provided insights into factors influencing adolescent diet and physical activity in rural India. Scarcity of basic resources limited adolescent diet and opportunities for physical activity. To achieve current nutritional and physical activity recommendations for adolescents requires improved infrastructure in these settings, changes which may accompany the current Indian social and economic transition.

To explore adolescents’ perceptions, knowledge and behaviours regarding nutrition and physical activity in low-income districts of Abidjan, Côte d’Ivoire, taking into consideration their caregivers’ perspectives.

Two investigators conducted six focus group discussions.

The study was carried out in two low-income suburbs, Yopougon and Port-Bouët, in Abidjan, Côte d’Ivoire.

Adolescents and their caregivers were recruited into the study via local head teachers and heads of settlement.

Overall, seventy-two participants, including forty-six adolescents and twenty-six caregivers, took part. Participants demonstrated good nutrition knowledge, relating nutritional health to a balanced diet and hygiene. Sustained physical activity was reported. However, adopting good practices was challenging due to participant’s economic circumstances. Their environment was a barrier to improving health due to dirtiness and violence, with a lack of space limiting the possibility to practice sport. Adolescents and their caregivers differed in their response to these constraints. Many caregivers felt powerless and suggested that a political response was the solution. Alternatively, adolescents were more likely to suggest new creative solutions such as youth-friendly centres within their community.

Participants were aware that their nutritional habits were not in line with what they had learnt to be good nutritional practices due to socio-economic constraints. Physical activity was part of adolescent life, but opportunities to exercise were restricted by their environment. Strategies for improving adolescent health in these settings need to be developed in collaboration with adolescents in a manner that accommodates their opinions and solutions.

To explore influences on the diet and physical activity of adolescents living in Mumbai slums, from the perspectives of adolescents and their caregivers.

Three investigators from Mumbai conducted six focus group discussions.

The study was conducted in suburban Mumbai slums.

Thirty-six adolescents (aged 10–12 and 15–17 years) and twenty-three caregivers were recruited through convenience sampling.

The findings highlighted the complex negotiations between adolescent and caregivers surrounding adolescent junk food consumption and physical activity opportunities. Caregivers learned recipes to prepare popular junk foods to encourage adolescents to eat more home-cooked, and less ‘outside’, food, yet adolescents still preferred to eat outside. To adolescents, the social aspect of eating junk food with friends was an important and enjoyable experience. Caregivers felt that they had no control over adolescents’ food choices, whereas adolescents felt their diets were dictated by their parents. Adolescents wanted to be physically active but were encouraged to focus on their academic studies instead. Gender was also a key driver of physical activity, with girls given less priority to use outside spaces due to cultural and religious factors, and parental fears for their safety.

These findings show that adolescents and caregivers have different agendas regarding adolescent diet. Adolescent girls have less opportunity for healthy exercise, and are more sedentary, than boys. Adolescents and caregivers need to be involved in designing effective interventions such as making space available for girls to be active, and smartphone games to encourage healthy eating or physical activity.

Crisis resolution teams (CRTs) offer brief, intensive home treatment for people experiencing mental health crisis. CRT implementation is highly variable; positive trial outcomes have not been reproduced in scaled-up CRT care.

To evaluate a 1-year programme to improve CRTs’ model fidelity in a non-masked, cluster-randomised trial (part of the Crisis team Optimisation and RElapse prevention (CORE) research programme, trial registration number: ISRCTN47185233).

Fifteen CRTs in England received an intervention, informed by the US Implementing Evidence-Based Practice project, involving support from a CRT facilitator, online implementation resources and regular team fidelity reviews. Ten control CRTs received no additional support. The primary outcome was patient satisfaction, measured by the Client Satisfaction Questionnaire (CSQ-8), completed by 15 patients per team at CRT discharge (n = 375). Secondary outcomes: CRT model fidelity, continuity of care, staff well-being, in-patient admissions and bed use and CRT readmissions were also evaluated.

All CRTs were retained in the trial. Median follow-up CSQ-8 score was 28 in each group: the adjusted average in the intervention group was higher than in the control group by 0.97 (95% CI −1.02 to 2.97) but this was not significant (P = 0.34). There were fewer in-patient admissions, lower in-patient bed use and better staff psychological health in intervention teams. Model fidelity rose in most intervention teams and was significantly higher than in control teams at follow-up. There were no significant effects for other outcomes.

The CRT service improvement programme did not achieve its primary aim of improving patient satisfaction. It showed some promise in improving CRT model fidelity and reducing acute in-patient admissions.
