Background: Sitting height (SH) and leg length (LL) help in assessing disproportionate growth. Anthropometric dissimilarity has been observed in different ethnicities. Aim: To (1) study sitting height and body proportions in children from different regions of India; and (2) compare sitting height and body proportions with data from other countries. Subjects and methods: This was a cross-sectional multicentric observational study, where 7961 (4328 boys) 3–18 year old children from five regions (north, south, east, west and central) were measured (height, weight and SH). Results: Boys from north India and girls from central India were taller and heavier (mean height 153.2 ± 18, 146.4 ± 11), while western boys and girls were the shortest (131.1 ± 20.7, 129.8 ± 19.5) (p

Background: Sitting height (StH) percentiles are not described for the Indian paediatric population. Aim: To generate multicentre StH percentile values for Indian children. Subjects and methods: A total of 7961 apparently healthy children (3–17 years old, Boys: 4328) randomly selected from 10 schools from six states of India were measured for height (ht), StH and weight during July 2016–October 2017. Results: The StH:Ht ratio was 0.52 (0.02) and was similar between boys and girls (p > 0.1). The ratio decreased in boys until the age of 14 years and then slightly increased; the lowest ratio was observed during 13–15 years. In girls, however, the StH:Ht ratio decreased until the age of 9 years and then plateaued until 15 years of age with a slight increase at 16 years; the lowest ratio was observed at the age of 12–13 years. Sitting height percentiles (3rd, 10th, 25th, 50th, 75th, 90th and 97th) were computed using LMS chartmaker. Conclusions: The results indicate that, during the pubertal years, the lower limb growth is more predominant than trunk growth. Further, this study provides smoothened percentile curves for sitting height in Indian children for the first time.

Objective and Aims: Overweight/obese children are at risk of developing type 2 diabetes mellitus. Random glucose elevations provide early warning signs of glycemic dysregulation. To assess random blood glucose (RBG) concentrations and risk factors associated with prediabetes in children aged 3-18 years from six Indian regions. Method: Multicenter, cross sectional, observational school-based study; multi-stage stratified random sampling was carried out. Height and weight measured; body mass index (BMI) was computed. RBG measured using a glucometer. National sample survey was used for dietary patterns. Data were analyzed using SPSS 25.0 for Windows. Setting: Study centers were from Maharashtra, Gujarat, Chhattisgarh, Assam, Tamil Nadu and Punjab from 40 selected schools. Participant: Children aged 3-18 years were measured. Results: Data on 14339 subjects (7413 boys) were analyzed. Prevalence of obesity was 5.8% and overweight-10.6%. Overall, 1% had low (7.2 mmol/L). With increasing mean BMI, there was increase in RBG concentrations. Children from Tamil Nadu were more likely to have RBG outside reference range compared to other regions (P < 0.05). Assam and Punjab had highest prevalence of RBG and BMI within reference range. Energy intake partly explained regional variations. Multivariate analysis showed male gender, urban residency, age >10 yrs (girls) and 13 yrs (boys), and overweight or obesity were predictive of prediabetes. Conclusion: Increased prevalence of overweight, obesity and prediabetes in Indian children are a matter of concern. Regional differences suggest that strategies to prevent obesity and combat perturbations in blood sugar may have to be customized.
