Objective: 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. Design: 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. Setting: 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). Participants: 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. Results: 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. Conclusions: 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. [ABSTRACT FROM AUTHOR]

Objective: 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. Design: Two investigators conducted six focus group discussions. Setting: The study was carried out in two low-income suburbs, Yopougon and Port-Bouët, in Abidjan, Côte d'Ivoire. Participants: Adolescents and their caregivers were recruited into the study via local head teachers and heads of settlement. Results: 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. Conclusions: 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. [ABSTRACT FROM AUTHOR]
