Rural Childhood Obesity - An Emerging Health Concern

How do adolescents classify foods as healthy and unhealthy?: A qualitative inquiry from rural India

Indian adolescents exhibit obesogenic dietary habits including low intake of fruits and vegetables and increasing consumption of fast food and carbonated beverages. Adolescents' classification of healthy and unhealthy foods is likely to have significant implications for their dietary behaviour, and consequently, their health. However, there is limited evidence about the ways Indian adolescents classify foods as healthy or unhealthy. Hence, this qualitative study was designed to explore how Indian adolescents classify nutritious or non-nutritious food choices. Convenience sampling was used to recruit the study participants from Tikari village in Uttar Pradesh, India. Underpinned by the social constructivist lens, the adolescents were interviewed face-to-face in Hindi. All the interactions were digitally recorded, transcribed verbatim, and translated into English prior to data analysis. Transcribed data were analysed thematically using inductive as well as deductive coding, and subsequently, conceptual themes were extracted. A total of thirty-nine adolescents (twenty boys; nineteen girls) aged 10-19 years participated in this qualitative inquiry. The adolescents classified healthy and unhealthy foods based on the following six themes: (i) Food groups and nutrients; (ii) Health and immunity; (iii) Type of ingredient; (iv) Place and time of food preparation; (v) Packaging; and (vi) Parental influence. These findings can inform school-based food literacy interventions to foster healthy dietary habits and cooking skills among Indian adolescents.

Indian adolescents' perceptions of packaged food and food labels - A qualitative inquiry

In the last two decades, India has witnessed a dramatic rise in the consumption of packaged foods, especially among adolescents. Food labelling is often recognised as an instrumental population-based approach which can enable consumers to make informed food choices by providing all the necessary details about the food product on the packaging. In the Indian context, where adolescent obesity and the ensuing non-communicable diseases are escalating, it is crucial to understand adolescents' views on the use of non-nutritious packaged foods and food labels. Therefore, the aim of this qualitative inquiry was to explore Indian adolescents' perceptions regarding the consumption of packaged food and use of food labels. Convenience sampling was employed to recruit 29 boys and 15 girls (aged 10-19 years) from rural Varanasi, India. Semi-structured, face-to-face interviews were conducted in the local language. Interview recordings were transcribed verbatim and translated to English. Narrative data were subjected to thematic analysis using NVivo software program. The adolescents reported frequent consumption of packaged food like potato chips, biscuits, chocolates, deep-fried Indian snacks both at school and home. Packaged foods were regarded as tasty, safe, and fresh. Brand name, date of expiry and cost were often read by the study respondents. Nevertheless, they reported difficulty in understanding other components of the label (e.g., nutrition information) and they were not aware of the negative impact of consuming unhealthy packaged foods. Nearly all the respondents insisted that food labels should be written in the local language for easy understanding. These emerging findings underscore the need to design school-based food literacy programs for vulnerable Indian adolescents to address obesity and diet-related complications in early adulthood.

Influence of ecoregional and lifestyle factors on growth and body composition of I ndian children and adolescents aged 9–18 years—A multicenter study

OBJECTIVES

Ecoregion comprises all the environmental factors such as climate, vegetation, geomorphology, and soil taken together. The objectives of this study were to (1) assess differences in growth and body composition (BC) in 9-18-year-old children and adolescents (CA), across six ecoregions of India, (2) evaluate and compare the magnitude of the effect of ecoregional and lifestyle factors (LSF) on growth and BC in urban (U) and rural (R) children and adolescents, and (3) reassess the applicability of Bergmann's Rule and Allen's Rule to humans.

SUBJECTS AND METHODS

Data on 1845 CA (925 boys; 920 girls) were collected (2016-2017) from urban and rural areas of six ecoregions of India. Anthropometric and BC parameters were measured; Z-scores were computed. Lifestyle Index score (LIS) based on LSF-(socioeconomic status [SES], diet, physical activity) was computed (categorized as low, medium, high-indicates better LSF). Univariate analysis was performed to estimate effect size.

RESULTS

Significant differences were observed in growth and BC across urban and rural ecoregions. CA with high LIS were taller and heavier than those with low LIS (p < .05). Ecoregion had greater effect on growth (Partial eta square (η² ) for R = 0.136 vs. U = 0.057) and BC (η² for R = 0.094 vs. U = 0.058) of rural CA than urban (p < .01). LSF had more effect on the BC of urban CA (η²  = 0.017) than rural (η²  = 0.002, p < .01).

CONCLUSION

Disparities among the six ecoregions were not large enough to fully support Bergmann's Rule and Allen's Rule. Ecoregion had greater effect on growth and BC of rural CA than urban, while lifestyle factors had more effect on the BC of urban CA.

A Study on New IAP 2015 Growth References in Rural South Indian Children

OBJECTIVES

To ascertain the utility of the new pan Indian 2015 IAP references in rural South Indian children and the ability of new IAP charts to recognise children with abnormal cardiometabolic risk factors in 10 to 16 y age group.

METHODS

Among school health camps conducted at two centres of Tamil Nadu- rural Vellore and rural Erode- height, weight, waist circumference, blood pressure, triceps skin-fold thickness and body fat percentage were measured by trained pediatricians and Z-scores calculated. The anthropometric measures were studied as per IAP 2015 references and compared to other national and international references. Their utility in identification of malnutrition and cardiometabolic risk ascertained.

RESULTS

A total of 420 children (210 from Erode and 210 from Vellore) in the age group of 10 to 16 y were included in the study. New IAP references recognized more short stature (4.2 vs. 3%), wasting (11 vs. 1.5%) and overweight (14.2 vs. 13.2%) children compared to old IAP charts. The Z-scores of anthropometric measures as per New IAP 2015 references had significant correlation with old IAP and other international data (p < 0.05). It was noted that new IAP charts could detect 83.3%, old IAP chart 50% and WHO 83.3% of subjects with malnutrition. New IAP charts could detect 70.3% cardiometabolic risk associated with over nutrition compared to old IAP (57.4%) and WHO (51.8%).

CONCLUSIONS

There is a significant prevalence of both under nutrition and overweight in rural setting. IAP 2015 reference is useful to diagnose children with under nutrition and overweight including abnormal cardiometabolic risk.
