ABSTRACT
Background: The reference cut-offs for overweight and obesity have evolved from the use of International obesity task force (IOTF) to extended IOTF and revised Indian Academy of Pediatrics (IAP) growth charts. Methods: Secondary analysis of anthropometric data of school-going children from Delhi in the year 2008, 2013 and 2015 was performed. The proportions of children with overweight, obesity, and undernutrition were checked for agreement using different diagnostic cutoffs, and compared at three-time points. Results: Among 8417 adolescents, weighted Kappa statistics showed good agreement between extended IOTF and IAP cutoffs (k=0.933; 95% CI 0.93-0.94), between eIOTF and IOTF (k=0.624; 95% CI 0.619 - 0.629) and between IAP and IOTF (k=0.654; 95% CI 0.645-0.662). A higher proportion of adolescents were diagnosed with obesity with extended IOTF and IAP charts than IOTF charts (P<0.001 for both genders). The mean (SD) BMI showed a rising trend for adolescents overall from 19.61 (3.89) kg/m2 in 2008, 20.44 (4.37) kg/m2 in 2013 and 20.88 (4.60) kg/m2 in 2015 (P<0.001). 158 adolescent (97 girls) were undernourished using combined IAP and extended IOTF criteria. Conclusion: Both extended IOTF and IAP charts showed good agreement for diagnosing overweight and obesity in adolescents. A secular trend in malnutrition was observed in adolescent girls.
ABSTRACT
Objective: To compare the adequacy and efficacy of differentdoses of vitamin D3 in pre-pubertal girls.Design: Cluster Randomized controlled trial.Setting: Public school in Delhi, India, between August 2015 andFebruary 2016.Participants: 216 healthy pre-pubertal girls, aged 6.1-11.8 years.Intervention: Daily supplementation with 600 IU (n=74), 1000 IU(n=67) or 2000 IU (n=75) of vitamin D3 under supervision for 6months.Outcome measures: Primary: Rise in serum 25 hydroxy VitaminD (25(OH)D); Secondary: Change in bone formation andresorption markers.Results: Following 6 months of supplementation, the mean (SD)rise in serum 25(OH)D was maximum with 2000 IU (24.09 (8.28)ng/mL), followed by with 1000 IU (17.96 (6.55) ng/mL) and 600 IU(15.48 (7.00) ng/mL). Serum 25(OH)D levels of ?20 ng/mL wereseen in 91% in 600 IU group , 97% in 1000 IU group and 100% in2000 IU group. The overall mean (SD) rise in urinary calciumcreatinine ratio (0.05 (0.28) to 0.13 (0.12) mg/mg), and serumprocollagen type I N-terminal propeptide (538.9 (199.78) to 655.5(218.24) ng/mL), and reduction in serum carboxy-terminaltelopeptide (0.745 (0.23) to 0.382 (0.23) ng/mL) was significant(P<0.01). The change in the above parameters was comparableamong the three groups after adjustment for age.Conclusion: Daily vitamin D supplementation with 600 IU to 2000IU for 6 months results in Vitamin D sufficiency in >90% of pre-pubertal girls
ABSTRACT
Background. The assessment of growth is crucial for child care and reference data are central to growth monitoring. We aimed to assess the height, weight and body mass index (BMI) of Indian schoolchildren in order to develop genderappropriate growth charts for children 5–18 years of age. Methods. Cross-sectional evaluation of anthropometric parameters (height, weight and BMI) was done in Indian schoolchildren (3–18 years) randomly selected from both fee-paying (upper socioeconomic strata) and non-fee paying (lower socioeconomic strata) schools from 4 regions (north, south, east and west) of India. A total of 106 843 children were evaluated, of which 42 214 children (19 303 boys, 22 911 girls) were from the lower socioeconomic strata and 64 629 children (34 411 boys, 30 218 girls) were from the upper socioeconomic strata. Normative charts, using the lambda–mu–sigma (LMS) method to smoothen the curves, were drawn from children belonging to the upper socioeconomic strata, in view of the gross discrepancy between the two socioeconomic strata. Results. Height, weight and BMI percentile (3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th and 97th) data were calculated and charts generated. The height of boys and girls was consistently higher at all ages when compared with earlier India data, but the final height was 2–4 cm lower than that reported in the WHO multicentre study of 2007. Weight centiles showed a rising trend both in boys and girls compared not only to earlier Indian data published in 1992, but also to that reported by the WHO multicentre study. The median weight at all ages in both boys and girls was approximately 4 kg more than that reported in affluent Indian children two decades earlier. Conclusion. This large nationwide study indicates secular trends in height, weight and BMI in Indian children from the upper socioeconomic strata. We suggest that the height and weight percentiles reported by us may be used as reference standards for India.
