RESUMEN
BACKGROUND: High adiposity is major risk factor for hypertension. Various anthropometric indices are used to assess excess fatness. OBJECTIVES: (1) To examine relationship of body mass index (BMI), waist circumference (WC), waist to height ratio (WHtR), triceps skin fold thickness (TSFT) and wrist measurements with blood pressure in children and adolescents 2) to suggest age- and gender-specific cutoffs for these indices in Indian children. METHODS: Cross-sectional school-based study on a random sample of 6380 children (6-18 yr old, 3501 boys) from five major cities in India. Height, weight, waist and wrist circumference, TSFT, and blood pressure were recorded. Children with systolic blood pressure (BP) and/or Diastolic BP >95th percentile were classified as hypertensive. RESULTS: Prevalence of overweight and obesity was 23.5% and 9.7%, respectively. Hypertension was observed in 5.6%. Multiple logistic regression (adjustments: age, gender) indicated double risk of hypertension for overweight and 7 times higher odds for obese than normal-weight children. Children with TSFT >95th centile for US children showed three times risk and with TSFT from 85th to 95th double risk of hypertension. Higher WC and WHtR exhibited 1.5 times risk and larger Wrist 1.3 times higher risk of hypertension (P<0.001). Receiver operating curve (ROC) analysis provided age-gender specific cut offs for the five indices to detect the risk of high BP. Area under ROC curves (AUC) for five indices were similar and greater in older age groups indicating equal sensitivity and specificity. Conclusion: Using age- and gender-specific cutoffs for BMI, TSFT, WC or WHtR may offer putative markers for early detection of hypertension. CONCLUSION: Using age- and gender-specific cutoffs for BMI, TSFT, WC or WHtR may offer putative markers for early detection of hypertension.

BACKGROUND: Indian children and adolescents have higher body fat percentage at a given body mass index than their Western counterparts. OBJECTIVE: To create gender-specific percentile curves for total body fat percentage (TBFP), total body fat mass (TBFM), fat mass index (FMI) and android:gynoid (A:G) ratio for screening adiposity in healthy Indian children. METHODS: Data on body composition by dual-energy X-ray absorptiometry were obtained from a cross-sectional study conducted from May 2006-July 2010 on 888 (462 boys) apparently healthy children from affluent area schools and colleges in Pune city, India. Reference percentile curves were derived for boys and girls for TBFP, TBFM, FMI and A:G ratio. These percentile curves were validated using data on metabolic syndrome risk components in separate sample of 332 (148 boys) children. RESULTS: The median TBFP increased little (4%) from 5 to 18 years of age in boys compared with that in girls (19%). TBFP percentiles showed plateau after 13 years of age in boys, whereas a steady increase was seen till 18 years in girls. The median TBFM increased less (7 kg) from 5 to 18 years in boys compared with that in girls (13.4 kg). The curve for median FMI in boys was relatively flat with FMI remaining near 3 kg m(-2) after 13 years of age, whereas in girls median FMI increased with age till about 15 years of age. A:G ratio curves increased with age in both boys and girls up to 18 years of age. In a separate sample of 332 children, according to percentiles developed in the current study, children with TBFP/TBFM/FMI percentiles between 85th and 95th or >95th percentile had significantly higher metabolic risk parameters as compared with those with <85th percentile (P<0.05). CONCLUSIONS: Percentile curves developed in the current study would be useful in assessment of adiposity and thus cardiometabolic risk in Indian children.

BACKGROUND: Studies assessing the relationship of BMI and BF with cardiometabolic (CM) risks in Indian children are scarce. OBJECTIVE: To assess the occurrence of cardiometabolic risk factors in Indian children and adolescents in relation to BMI and body fat and to study their association with body fat distribution. METHODS: 286 children and adolescents (mean age 11.2 ± 2.6 years, 139 boys) were recruited from routine health checks and schools. Anthropometry and blood pressure were recorded, total body fat (BF) and fat distribution (android and gynoid) were measured by Dual Energy X-ray Absorptiometry. Fasting plasma glucose, lipid profile and insulin were also measured. RESULTS: When the study cohort was divided as per their BMI and biochemical cardiometabolic risk factors, 8% children had normal BMI with abnormal biochemical parameters while 40% children had abnormal BMI but normal biochemical parameters. CONCLUSION: There are normal weight children with cardiometabolic risks. There was an increase in the occurrence of cardiometabolic risk factors with increased android distribution of fat (p-value < 0.05).

OBJECTIVE: To develop age and sex specific cut offs for BMI to screen for overweight and obesity in Indian children linked to an adult BMI of 23 and 28 kg/m2 respectively, using contemporary Indian data. DESIGN: Cross-sectional. SETTING: Multicentric, School based. PARTICIPANTS: 19834 children were measured from 11 affluent schools from five major geographical regions of India. Data were analyzed using the LMS method, which constructs growth reference percentiles adjusted for skewness. RESULTS: Compared to the cut-offs suggested for European populations and those by the Indian Academy of Pediatrics 2007 Guidelines, the age and sex specific cut off points for body mass index for overweight and obesity for Indian children suggested by this study are lower. CONCLUSIONS: Contemporary cross-sectional age and sex specific BMI cut-offs for Indian children linked to Asian cut-offs of 23 and 28 kg/m2 for the assessment of risk of overweight and obesity, respectively are presented.

BACKGROUND/OBJECTIVES: Low habitual dietary calcium intake and vitamin D deficiency are common among Indian children. Using 'laddoo', an Indian snack, as a vehicle for administering calcium and vitamin D supplements, a randomized double-blind controlled trial was conducted for 12 months to assess its efficacy on total body less head (TBLH) bone mineral content (BMC) in underprivileged toddlers. SUBJECTS/METHODS: A total of 60 toddlers (mean age 2.7±0.52 years, boys=31) were randomized to two groups, (i) study group receiving one calcium fortified laddoo (cereal-legume snack) containing 405 mg calcium per day and (ii) control receiving a non-fortified laddoo, containing 156 mg of indigenous calcium. Both groups also received a laddoo fortified with 30,000 IU of vitamin D(3) per month. Outcome measures included TBLH bone area (BA) and TBLH BMC by GE-Lunar DPX Pro Pencil Beam Dual-Energy X-ray absorptiometry. RESULTS: At baseline, mean energy, protein and calcium intakes were 71, 72 and 47% of Indian Recommended Dietary allowances. In all, 87 and 83% toddlers were hypocalcaemia and vitamin D deficient, respectively. Mean TBLH BMC was 289.5±45.8 g. Post supplementation, mean TBLH BMC of study group showed a significantly greater (P<0.01) increase of 35% as against 28% in controls and the difference remained significant after adjusting for vitamin D status, calcium intake, height and TBLH BA. CONCLUSIONS: Daily supplementation with calcium fortified laddoo, and monthly vitamin D supplement resulted in a significant increase in TBLH BMC of underprivileged toddlers. We believe that such strategies have the potential of addressing nutritional problems in developing countries.

OBJECTIVES: To estimate prevalence of overweight and obesity in apparently healthy children from five zones of India in the age group of 2 to 17 years and to examine trends in body mass index (BMI) during the last two decades with respect to published growth data. METHODS: A multicentric study was conducted in eleven affluent urban schools from five geographical zones of India. A total of 20 243 children (1 823 - central zone, 2 092 - east zone, 5 526 - north zone, 3 357 - south zone, and 7 445 - west zone) in the age group of 2-17 years were studied. Height and weight were measured and BMI was calculated (kg/m(2)). WHO Anthro plus was used to calculate Z-scores for height, weight and BMI. A comparison between study population and previously available nationally representative (1989) data was performed for each age-sex group. International Obesity Task Force (IOTF) and WHO cut-offs were used to calculate the percentage prevalence of overweight and obesity. RESULTS: The overall prevalence of overweight and obesity was 18.2% by the IOTF classification and 23.9% by the WHO standards. The prevalence of overweight and obesity was higher in boys than girls. Mean BMI values were significantly higher than those reported in the 1989 data from 5-17 years at all ages and for both sexes. CONCLUSION: The rising trend of BMI in Indian children and adolescents observed in this multicentric study rings alarm bells in terms of associated adverse health consequences in adulthood.

OBJECTIVE: To identify the genetic cause of transient neonatal diabetes mellitus in three siblings from an Indian family. METHODS: Case reports with clinical and molecular evaluation of an activating mutation in the KCNJ11 gene are presented. We describe an Indian family with two asymptomatic parents with 3 children presenting with hyperglycemia at 6, 1.5 and 1 month of age respectively. Blood glucose levels at presentation were 22.2, 18.3 and 20 mmol/L and the diabetes remitted in all three children by 5 years of age. None of the affected siblings had dysmorphism or neurological abnormalities. Diabetes relapsed in the oldest sibling at 9.4 years of age and she is now euglycemic on 1mg/Kg of Glibenclamide twice a day. RESULTS: A novel heterozygous missense mutation (G53V) in the KCNJ11 gene was identified in all 3 affected children and the father. CONCLUSIONS: Our report suggests that screening for KCNJ11 mutations is appropriate in patients diagnosed with neonatal diabetes as it provides valuable information concerning possible course of the disease and choice of treatment.

OBJECTIVE: To study the role of sunlight exposure in determining the vitamin D status of underprivileged toddlers. METHODS: Height and weight were measured, clinical examination was performed, Food Frequency Questionnaire was administered and history of sunlight exposure was obtained in all (61) toddlers attending daytime crèche (Group B). Ionised calcium (iCa), inorganic Phosphorous (iP), alkaline phosphatase activity (ALP), serum parathyroid hormone (PTH) and 25 Hydroxy vitamin D (25OHD) were measured. Data were compared with results of a survey measuring similar parameters in 51 (of 251 eligible) toddlers from the same slum (Group A). RESULTS: 111 children (mean age 2.6 yr (0.7), boys 56) were studied. Prevalence of hypovitaminosis D was 77% in group B toddlers (46 of 60) and 16.4% (10 of 61) had rickets, while none of the group A toddlers had 25OHD levels below 30 nmol/L. Four children (7.8%) from Group A as against 24 (42.9%) from Group B, had sunshine exposure of < 30 minutes per day. CONCLUSION: Underprivileged toddlers who were deprived of sunlight had a much greater incidence of hypovitaminosis D and frank rickets. The study has important public health implications and underscores the necessity for sunlight exposure in young children.

BACKGROUND: The assessment of growth is crucial in child care and reference data are central to growth monitoring. As the pattern of growth of a population changes with time it is recommended that references be updated regularly. OBJECTIVE: To produce contemporary growth curves for Indian children from 5-18 years for height, weight and BMI. DESIGN: Cross-sectional. SETTING: Multicentric, School based. PARTICIPANTS: 19834 children were measured from 10 affluent schools from five major geographical regions of India. Data were analyzed on 18666 children (10496 boys and 8170 girls) using the LMS method and smoothed percentiles 2007 were produced. RESULTS: Compared to the 1989 data, median height at 18 years was 0.6 cm greater for boys but unchanged for girls, while the 97th height percentile had increased by 1.7 cm for boys and 2 cm for girls. Boys and girls were heavier and taller at almost all ages. The study also showed that boys and girls were taller at a younger age. CONCLUSIONS: Contemporary cross sectional reference percentile curves for height, weight and body mass index for the assessment of physical growth of present day Indian children are presented.

Low serum vitamin B(12) (V B(12)) and hyperhomocysteinemia have been reported in asymptomatic Asian Indian men. We studied the prevalence of V B(12) deficiency and hyperhomocysteinemia in 51 asymptomatic toddlers, from Pune, India. V B(12) levels were low and total serum homocysteine was high in 14% and homocysteine levels were significantly higher in boys. Programming for cardiovascular risk in adulthood possibly starts at a very young age through the homocysteine axis.

OBJECTIVE: Of this pilot study was to assess the iron status and dietary intake of 1-3 year-old apparently healthy toddlers of the lower socio-economic class, and the effect of eight weeks intervention with liquid oral iron in an urban slum in Pune, India. METHODS: 50 toddlers (M= 25, F= 25) with mean age of 2.4 years (SD 0.82) were evaluated. Anthropometry, Food Frequency Questionnaire, a hemogram and ferritin were measured. Twenty mg of elemental iron was given to all toddlers. After 8 weeks clinical examination, anthropometry, hemoglobin (HGB) and Ferritin were measured. RESULTS: Prevalence of anemia was 66% (HGB <11 gm %) and ferritin (iron stores) were low (< 12 microgm/L) in 45 (90%). After therapy prevalence of anemia was 30%. There was a significant difference in the HGB and ferritin levels of children after eight weeks of therapy (p<0.001). CONCLUSION: The prevalence of anemia decreased from 66 to 30% after treatment with liquid iron. We propose that all concerned in the care of toddlers should join the fight against anemia and prescribe iron to all toddlers when they are seen for minor ailments.

OBJECTIVE: This study was undertaken to analyze the outcome of children with DKA treated with a modified protocol at a tertiary level teaching hospital PICU in Pune, Maharashatra. METHODS: We retrospectively analyzed case records of 12 patients (8 males and 4 females) with DKA (11 new and 1 readmission) admitted in our PICU from January 2005 to June 2006. Patients were managed according to a modified protocol (that is with less intensive biochemical monitoring when compared with standard book protocols). Laboratory parameters measured were blood glucose, urinary ketones, electrolytes, urea creatinine, arterial blood gas (ABG) and infectious screen. Treatment included fluid therapy and insulin infusion- 0.1 u/Kg short acting intravenously followed by 0.1 u/Kg/hr. No bicarbonate was administered as a bolus. RESULTS: Total fluid deficit was corrected slowly over a period of 36 hr. The median time to normalize ABG was 19 hr (5.3-39) while the median time for the urinary ketones to disappear was 1day (1-3). The child to nurse ratio was 1:2, there were 2 pediatric residents in house all 24 hr with an intensivist and pediatric endocrinologist on call. CONCLUSION: We have shown that when DKA is managed in a PICU setting using modified protocol, the outcome is good and complications such as brain edema can be prevented.
