'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.

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.

aDolescent and prEconception health peRspectiVe of Adult Non-communicable diseases (DERVAN): protocol for rural prospective adolescent girls cohort study in Ratnagiri district of Konkan region of India (DERVAN-1).

INTRODUCTION: Precise impact of nutritional insufficiencies in adolescence as a risk factor for non-communicable diseases (NCD) in later life as adults remains largely unknown.We are conducting research into the effects of nutrition on adolescent girls of Ratnagiri district by a prospective cohort study (aDolescent and prEconception health peRspectiVe of Adult Non-communicable diseases cohort). Our study focuses on the physical health, nutritional parameters and cognitive profiles of adolescent girls, during the prenatal and postnatal period and we aim to follow this cohort and their offspring for 20 years. METHODS AND ANALYSIS: Cohort recruitment began in June 2019. Our aim is to recruit more than 1500 adolescent girls, age 16-18 years, over a period of 3 years. The recruit's cognition, diet and physical activity will be recorded. The following investigations will be performed: body composition by anthropometry and bioimpedence, and blood pressure, fasting blood sample to measure glucose, insulin, lipids, micronutrients and hormones, abdominal ultrasonography to measure liver, pancreas and kidneys.A biorepository has been created for long-term storage of blood, urine and saliva samples for future analysis. By this longitudinal study, we aim to identify the effects of malnutrition on the behavioural and biological measures in adolescent subjects and evaluate if these are associated with the onset of NCDs in adulthood. ETHICS AND DISSEMINATION: Institutional Ethic Committee (IEC) of BKL Walawalkar Rural Medical College and Hospital has granted the permission to carry out the study. IEC is registered with Government of India. Its registration code is EC/755/INST/MH/2015/RR-18. It is not a clinical trial but as required we have also registered the study on Clinical Trial Registry of India (CTRI). The registration code is CTRI/2019/04/018453.Appropriate written informed consent and assent are obtained from the parents and the adolescent girls, respectively. We plan to publish our results in peer-reviewed journals.
