How do we improve adolescent diet and physical activity in India and sub-Saharan Africa? Findings from the Transforming Adolescent Lives through Nutrition (TALENT) consortium

Objective: Adolescent diet, physical activity and nutritional status are generally known to be sub-optimal. This is an introduction to a special issue of papers devoted to exploring factors affecting diet and physical activity in adolescents, including food insecure and vulnerable groups. Setting Eight settings including urban, peri-urban and rural across sites from five different low- and middle-income countries. Design: Focus groups with adolescents and caregivers carried out by trained researchers. Results: Our results show that adolescents, even in poor settings, know about healthy diet and lifestyles. They want to have energy, feel happy, look good and live longer, but their desire for autonomy, a need to ‘belong’ in their peer group, plus vulnerability to marketing exploiting their aspirations, leads them to make unhealthy choices. They describe significant gender, culture and context-specific barriers. For example, urban adolescents had easy access to energy dense, unhealthy foods bought outside the home, whereas junk foods were only beginning to permeate rural sites. Among adolescents in Indian sites, pressure to excel in exams meant that academic studies were squeezing out physical activity time. Conclusions: Interventions to improve adolescents’ diets and physical activity levels must therefore address structural and environmental issues and influences in their homes and schools, since it is clear that their food and activity choices are the product of an interacting complex of factors. In the next phase of work, the Transforming Adolescent Lives through Nutrition consortium will employ groups of adolescents, caregivers and local stakeholders in each site to develop interventions to improve adolescent nutritional status.

‘I should be disease free, healthy and be happy in whatever I do’: a cross-country analysis of drivers of adolescent diet and physical activity in different low- and middle-income contexts

Objective: To explore perceptions of how context shapes adolescent diet and physical activity in eight low- and middle-income (LMIC) sites at different stages of societal and economic transition. Design: Novel qualitative secondary analysis of eight data sets generated as part of the international Transforming Adolescent Lives through Nutrition (TALENT) collaboration. Setting: Diverse sites in India and Sub-Saharan Africa. Participants: Fifty-two focus group discussions with 491 participants (303 adolescents aged 10–17 years; 188 caregivers). Results: Analysis of pooled qualitative data identified three themes: (1) transitions in generational nutrition education and knowledge; (2) transition in caregiver–adolescent power balance and (3) the implications of societal and economic transition for diet and physical activity. Adolescents in urban and peri-urban areas could readily access ‘junk’ food. Diets in rural settings were determined by tradition, seasonality and affordability. Physical activity was inhibited by site-specific factors including lack of space and crime in urban settings, and the prioritisation of academic performance. Gender influenced physical activity across all sites, with girls afforded fewer opportunities. Conclusions: Interventions to improve adolescent diet and physical activity in LMIC need to be complex, context-specific and responsive to transitions at the individual, economic and societal levels. Moreover, solutions need to acknowledge gender inequalities in different contexts, as well as structural and cultural influences on diet and physical activity in resource-limited settings. Programmes need to be effective in engaging and reconciling adolescents’ and caregivers’ perspectives. Consequently, there is a need for action at both the community-household level and also through policy.

Adolescent diet and physical activity in the context of economic, social and nutrition transition in rural Maharashtra, India: a qualitative study

Objective: 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. Design: 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. Setting: Villages approximately 40–60 km from the city of Pune in the state of Maharashtra, India. Participants: 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). Results: 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. Conclusions: 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.

Exploring influences on adolescent diet and physical activity in rural Gambia, West Africa: food insecurity, culture and the natural environment

Objective: To explore, from the perspectives of adolescents and caregivers, and using qualitative methods, influences on adolescent diet and physical activity in rural Gambia. Design: Six focus group discussions (FGD) with adolescents and caregivers were conducted. Thematic analysis was employed across the data set. Setting: Rural region of The Gambia, West Africa. Participants: 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). Results: 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. Conclusions: 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.

Social, economic and cultural influences on adolescent nutrition and physical activity in Jimma, Ethiopia: perspectives from adolescents and their caregivers

Objective: To explore influences on adolescent diet and physical activity, from the perspectives of adolescents and their caregivers, in Jimma, Ethiopia. Design: Qualitative design, using focus group discussions (FGD). Setting: A low-income setting in Jimma, Ethiopia. Participants: Five FGD with adolescents aged 10–12 years and 15–17 years (n 41) and three FGD with parents (n 22) were conducted. Results: 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. Conclusions: 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.

What shapes adolescents’ diet and physical activity habits in rural Konkan, India? Adolescents’ and caregivers’ perspectives

Objective: To explore, adolescents’ and caregivers’ perspectives, about shaping of diet and physical activity habits in rural Konkan, India. Design: Five focus group discussions (FGD) were conducted with adolescents and two with caregivers. Data were analysed using thematic analysis. Setting: FGD were conducted in secondary schools located in remote rural villages in the Ratnagiri district, Konkan region, Maharashtra, India. Participants: 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. Results: 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. Conclusion: 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.

Diet quality and depressive symptoms in adolescence: no cross-sectional or prospective associations following adjustment for covariates

ObjectiveAdolescence is a critical period for development of depression and understanding of behavioural risk factors is needed to support appropriate preventive strategies. We examined associations between adolescent diet quality and depressive symptoms, cross-sectionally and prospectively, in a large community cohort, adjusting for behavioural and psychosocial covariates.DesignProspective community-based cohort study (ROOTS).SettingSecondary schools in Cambridgeshire and Suffolk, UK.SubjectsStudy participants (n 603) who completed 4 d diet diaries at age 14 years and reported depressive symptoms (Moods and Feelings Questionnaire (MFQ)) at 14 and 17 years of age.ResultsDiet data were processed to derive a Mediterranean diet score (MDS) and daily servings of fruit and vegetables, and fish. At age 14 years, a negative association between fruit and vegetable intake and MFQ score was seen in the unadjusted cross-sectional regression model (β=−0·40; 95 % CI −0·71,−0·10), but adjustment for behavioural covariates, including smoking and alcohol consumption, attenuated this association. Fish intake and MDS were not cross-sectionally associated with MFQ score. No prospective associations were found between MDS, fruit and vegetable intake or fish intake and later MFQ score.ConclusionsDiet quality was not associated with depressive symptoms in mid-adolescence. Previously reported associations in this age range may be due to confounding. Further longitudinal studies are needed that investigate associations between adolescent diet and depression across different time frames and populations, ensuring appropriate adjustment for covariates.
