Association between yoga and related contextual factors with moderate-to-vigorous physical activity among children and youth aged 5 to 17 years across five Indian states.

Physical inactivity is one of the four key preventable risk factors, along with unhealthy diet, tobacco use, and alcohol consumption, underlying most noncommunicable diseases. Promoting physical activity is particularly important among children and youth, whose active living behaviours often track into adulthood. Incorporating yoga, an ancient practice that originated in India, can be a culturally-appropriate strategy to promote physical activity in India. However, there is little evidence on whether yoga practice is associated with moderate-to-vigorous physical activity (MVPA) accumulation. Thus, this study aims to understand how yoga practice is associated with MVPA among children and youth in India. Data for this study were obtained during the coronavirus disease lockdown in 2021. Online surveys capturing MVPA, yoga practice, contextual factors, and sociodemographic characteristics, were completed by 5 to 17-year-old children and youth in partnership with 41 schools across 28 urban and rural locations in five states. Linear regression analyses were conducted to assess the association between yoga practice and MVPA. After controlling for age, gender, and location, yoga practice was significantly associated with MVPA among children and youth (ß = 0.634, p < 0.000). These findings highlight the value of culturally-appropriate activities such as yoga, to promote physical activity among children and youth. Yoga practice might have a particularly positive impact on physical activity among children and youth across the world, owing to its growing global prevalence.

Natural history of Wolcott-Rallison syndrome: A systematic review and follow-up study.

BACKGROUND AND AIMS: To systematically review the literature for reports on Wolcott-Rallison syndrome, focusing on the spectrum and natural history, genotype-phenotype correlations, patient and native liver survival, and long-term outcomes. METHODS: PubMed, Livio, Google Scholar, Scopus and Web of Science databases were searched. Data on genotype, phenotype, therapy, cause of death and follow-up were extracted. Survival and correlation analyses were performed. RESULTS: Sixty-two studies with 159 patients met the inclusion criteria and additional 30 WRS individuals were collected by personal contact. The median age of presentation was 2.5 months (IQR 2) and of death was 36 months (IQR 50.75). The most frequent clinical feature was neonatal diabetes in all patients, followed by liver impairment in 73%, impaired growth in 72%, skeletal abnormalities in 59.8%, the nervous system in 37.6%, the kidney in 35.4%, insufficient haematopoiesis in 34.4%, hypothyroidism in 14.8% and exocrine pancreas insufficiency in 10.6%. Episodes of acute liver failure were frequently reported. Liver transplantation was performed in six, combined liver-pancreas in one and combined liver-pancreas-kidney transplantation in two individuals. Patient survival was significantly better in the transplant cohort (p = .0057). One-, five- and ten-year patient survival rates were 89.4%, 65.5% and 53.1%, respectively. Liver failure was reported as the leading cause of death in 17.9% of cases. Overall survival was better in individuals with missense mutations (p = .013). CONCLUSION: Wolcott-Rallison syndrome has variable clinical courses. Overall survival is better in individuals with missense mutations. Liver- or multi-organ transplantation is a feasible treatment option to improve survival.

Longitudinal assessment of auxological parameters, adult height outcome and its determinants in leuprolide-treated Indian girls with idiopathic central precocious puberty.

OBJECTIVES: To assess auxological parameters, adult height outcome and its determinants in Indian girls with idiopathic central precocious puberty (iCPP) treated with gonadotropin-releasing hormone analogues (GnRHa). METHODS: Retrospective study. Inclusion: data on girls with iCPP from initiation to stopping GnRHa (n=179). Exclusion: boys, peripheral, organic central precocity. RESULTS: Mean age of starting GnRHa: 8.2± 1.1 years, duration: 2.8± 1.2 years. 11.7 % had attained menarche at first presentation. The difference between bone (BA) and chronological (CA) ages reduced significantly from 2.6± 0.9 years (onset) to 1.6± 0.8 years (cessation). Weight, BMI Z-scores increased (p<0.01), height Z-scores decreased (0.8 vs. 0.6; p<0.01), predicted adult height (PAH) and Z-scores improved by 3.5 cm, 0.5 SDS following treatment (p<0.01). Overweight/obese girls (vs. normal BMI) were taller, with more advanced BA at starting (height Z-score: 0.7 vs. 1.0, BA-CA: 2.2 vs. 2.9 years), stopping (height Z-score: 0.5 vs. 0.9, BA-CA: 1.4 vs. 1.9 years) treatment, but showed no difference in PAH at starting, stopping treatment. Adult height data (n=58) revealed 1.9 cm gain above target height. Adult height Z-scores significantly exceeded target height Z-scores (p<0.01). Mean adult height (157.1± 5.8 cm) crossed PAH at starting treatment (155.9± 6.4 cm) but remained 1.6 cm lesser than PAH at cessation. Adult weight, BMI Z-scores (-0.2± 1.3, -0.1± 1.2) were significantly lower (p<0.01) than those at stopping GnRHa. Height gain adjusted for age at starting GnRHa correlated negatively with height, weight, BMI, Tanner-staging, BA, FSH, Estradiol at treatment onset, BA at cessation, and correlated positively with treatment duration. CONCLUSIONS: GnRHa treatment in Indian girls with iCPP resulted in improved PAH, decelerated bone age advancement and growth velocity. Most girls achieved adult height within target range, surpassing PAH at treatment initiation. Lesser anthropometric, sexual, skeletal maturity, lower baseline FSH, estradiol, longer treatment duration, less advanced BA at stopping GnRHa may translate into better adult height outcomes.

Assessment of pubertal onset and disorders of puberty in Indian children and youth with type-1 diabetes.

OBJECTIVES: Disorders of pubertal development are enlisted as associated conditions in children and adolescents with type-1 diabetes (T1D). We conducted this study with objective (1) To estimate the median age at onset of puberty and luteinizing hormone (LH) and sex-steroid concentrations in Indian adolescents with T1D and (2) To assess the impact of puberty on glycemic control and insulin resistance (IR). METHODS: This cross-sectional study included 399 children and youth aged 6-23 years with T1D. Demographic, anthropometric, biochemical and pelvic ultrasound data were collected using standard protocols. IR was calculated using estimated glucose disposal rate and puberty was assessed using Tanner staging. RESULTS: Median age at onset of thelarche, pubarche and menarche were 11.3, 11.4 and 12.8 years in girls and that of gonadarche and pubarche were 10.6 and 12.7 years for boys. The mean LH and sex-steroid concentrations of subjects with T1D were similar to healthy subjects at each stage of puberty. The cut-offs of LH and sex-steroids derived from healthy Indian children yielded high sensitivity and specificity in determining pubertal onset. The prevalence of precocity, delayed puberty, ovarian cysts and polycystic ovaries was 0.9 , 5.1, 5.1 and 8.6 %, respectively. Glycaemic control and insulin sensitivity was poor in pubertal subjects. CONCLUSIONS: The age at onset of puberty, LH, and sex-steroid concentrations in subjects with T1D were like otherwise healthy Indian children with poor glycemic control and IR in pubertal subjects. Although most complications of T1D are associated with poor glycemic control, pubertal disorders were significantly low despite the less-than-optimal glycemic control.

Response to sirolimus in a case of diffuse congenital hyperinsulinaemic hypoglycaemia due to homozygous KCNJ11 mutation.

We present a case of a male neonate with refractory and persistent neonatal hypoglycaemia not responding to octreotide. On evaluation for hypoglycaemia, his cortisol was within the reference range while the serum insulin concentrations were high. Gallium-68 dotatate scan (GA-68 DOTA) showed diffuse pancreatic involvement. Genetic diagnosis of congenital hyperinsulinaemic hypoglycaemia due to KCNJ11 mutation was made. He was started on tablet sirolimus, after which the child was off all other medication and was euglycaemic. However, he developed bilateral pneumonia leading to acute respiratory distress syndrome with refractory shock. Our case highlights the response to sirolimus in a case of congenital hyperinsulinaemia (CHI) due to KCNJ11 mutation and severe adverse event thereafter.

Calcium deficiency worldwide: prevalence of inadequate intakes and associated health outcomes.

Dietary calcium deficiency is considered to be widespread globally, with published estimates suggesting that approximately half of the world's population has inadequate access to dietary calcium. Calcium is essential for bone health, but inadequate intakes have also been linked to other health outcomes, including pregnancy complications, cancers, and cardiovascular disease. Populations in low- and middle-income countries (LMICs) are at greatest risk of low calcium intakes, although many individuals in high-income countries (HICs) also do not meet recommendations. Paradoxically, many LMICs with lower calcium intakes show lower rates of osteoporotic fracture as compared with HICs, though data are sparse. Calcium intake recommendations vary across agencies and may need to be customized based on other dietary factors, health-related behaviors, or the risk of calcium-related health outcomes. The lack of standard methods to assess the calcium status of an individual or population has challenged efforts to estimate the prevalence of calcium deficiency and the global burden of related adverse health consequences. This paper aims to consolidate available evidence related to the global prevalence of inadequate calcium intakes and associated health outcomes, with the goal of providing a foundation for developing policies and population-level interventions to safely improve calcium intake and status where necessary.

Rare case of renal Ewing sarcoma presenting as ectopic Cushing syndrome in a 12-year-old girl.

We present a 12-year-old girl with recent onset weight gain and purple striae over the abdomen. Examination revealed her to be hypertensive. On evaluation for Cushing syndrome (CS), her cortisol and adrenocorticotropic hormone (ACTH) were found to be high. MRI brain showed a suspicious lesion (thought to be pituitary microadenoma). Inferior petrosal sinus sampling was not conclusive of pituitary source of ACTH. High dose dexamethasone suppression test confirmed an ectopic source of ACTH secretion and CT scan revealed a mass in the right kidney which was laparoscopically excised. Histopathology and immunohistochemistry confirmed Ewing sarcoma. Our case highlights the rare presentation of renal Ewing sarcoma (RES) as CS. To the best of our knowledge, this is only the second case report of RES/primitive neuroectodermal tumour of the kidney presenting as CS in paediatric age group and first with a concomitant pituitary incidentaloma.

Reference centile curves for mid-upper arm circumference for assessment of under- and overnutrition in school-aged Indian children and adolescents.

OBJECTIVES: Malnutrition is common in developing countries and is not restricted to young children. It has been suggested that measuring mid-upper arm circumference (MUAC) is an easy, accurate, and low-cost method of identifying malnutrition in the early stages. The aims of this study were to construct age- and sex-specific MUAC reference centiles, and to define and validate cutoffs for assessment of under- and overnutrition in Indian children 5 to 17 y of age. METHODS: This was a cross-sectional, multicentric, observational study conducted in seven schools in seven states from June 2018 to November 2019. The study included 6680 healthy 5- to17-y-old children. MUAC was measured using non-stretch tapes (UNICEF). Sex-specific MUAC percentiles were computed for age and height. Cutoffs for MUAC z-scores for thinness and overnutrition were defined and validated for healthy school children (n = 726) and children with cancer (n = 500). RESULTS: Reference centiles for MUAC for age (and height) for boys and girls are presented. Cutoffs defined for thinness and for obesity were -0.7 and +1.5 z-score, respectively (corresponding to 25th and 95th percentiles of the MUAC for age/height). For ease of use, rounded cutoffs for thinness were 16 and 18.5 cm from 5 to 9 and 10 to 14 y of age, respectively, in both sexes, and a cutoff of 22 cm in boys and 20 cm in girl from 15 to 17 y of age. For obesity, 20 and 25.5 cm from 5 to 9 and 10 to 14 y of age, respectively, in both girls and boys and a rounded cutoff of 29 cm in boys and 27 cm in girls from 15 to17 y are proposed. CONCLUSIONS: We presented MUAC percentiles and cutoffs for screening for thinness and overnutrition in Indian children from 5 to 17 y of age. These data may also be used in children with cancer and other chronic disorders with growth failure.

Long-term follow-up of a child with Wolcott-Rallison syndrome.

Wolcott-Rallison syndrome (WRS), the most common cause of permanent neonatal diabetes mellitus (DM) in consanguineous families, has a poor prognosis, with a mean survival of 5.8 years. Majority of children with WRS succumb to the disease in the first decade of life. We present the long-term follow-up of an 8-year-2-month-old girl with genetically proven WRS who was born to a non-consanguineous parentage. She is on basal bolus regimen of insulin therapy for DM. In addition, she was noted to have features of skeletal dysplasia at 3 years and 3 months of age, which has led to her short stature. Surprisingly, she has had no episodes of hepatitis or liver dysfunction so far, which is frequently seen in children with WRS. To the best of our knowledge, she is the oldest surviving patient with WRS reported in India and South Asia.

Assessment of Bone Density by DXA in Poorly Controlled Children With ß-Thalassemia: Correction for Hepatic Iron Overload by Manual Analysis.

INTRODUCTION: Beta thalassemia major (BTM) is characterized by anemia and iron overload, especially with inadequate chelation therapy. Dual energy x-ray absorptiometry software (DXA) may misanalyse bone measurements due to iron deposition in organs such as the liver. Our objective was to study difference between the posterior-anterior spine measurements of bone mineral content (BMC), area (BA) and density (BMD) in poorly chelated beta thalassemia patients with and without inclusion of the liver in the DXA analysis. METHODS: We studied hemoglobin and serum ferritin concentrations in 208 patients with BTM (children n = 177, young adults n = 31). Posteroanterior spine measurements BMC, BA and areal BMD were performed using a GE iDXA. Using the tissue point typing feature (EnCore software, version 16), analysis was carried out including and excluding (manually) the iron overloaded liver. Machine generated Z-scores of L1-L4 BMD were used for analysis. RESULTS: The mean age of the study group was 12.9 ± 5.4 yr. Mean hemoglobin and serum ferritin concentrations were 8.0 ± 1.7 g/dl and 2256.9 ± 1978.0 ng/ml, respectively. The mean BMC, BA, and aBMD at the lumbar spine were 23.2 ± 11.4 g, 29.9 ± 8.5 cm2 and 0.736 ± 0.173 g/cm2 respectively with inclusion of liver that is standard machine analysis. After the liver was excluded from the analysis, the mean BMC, BA, and aBMD were 23.9 ± 11.6 g, 30.0 ± 8.6 cm2 and 0.757 ±0.173 g/cm2, respectively and the BMC and aBMD were significantly greater (p < 0.05). Mean BMD Z-score was -1.5 ± 1.2, which significantly (p < 0.05) improved to -1.3 ± 1.2 after exclusion of the liver from the analysis. CONCLUSION: In poorly chelated patients with thalassemia, inclusion of the iron-overloaded liver in the tissue analysis may exaggerate the deficit in bone parameters. Iron overloaded tissues need to be manually excluded during analysis of the PA spine.

Intussusception as a rare clinical presentation of a child with type 1 diabetes and diabetic ketoacidosis.

Intussusception in children is mainly idiopathic or due to a viral aetiology. Occasionally, pathological lead points like Meckel diverticulum or rarely metabolic causes like hyperglycaemia can result in formation of an intussusception. We describe the case of a boy with diabetic ketoacidosis presenting with abdominal pain. Despite correction of acidosis, the gastrointestinal symptoms persisted for which an ultrasonography of the abdomen was performed. It revealed an ileo-ileal intussusception, which was confirmed by a CT scan. He underwent an exploratory laparotomy. After reduction of the intussusception, a Meckel diverticulum was found as the lead point that was then resected. We present a case of a child with type 1 diabetes having an intussusception due to Meckel diverticulum, which was probably made worse by the decreased intestinal motility due to hyperglycaemia. Intussusception should thus be suspected in patients with diabetic ketoacidosis if the pain is persistent despite correction of acidosis.

Rare association of Beckwith-Wiedemann syndrome with Hirschsprung's disease in an infant with hypoglycemia.

Hypoglycaemic due to congenital hyperinsulinism in Beckwith-Wiedemann syndrome is commonly seen. It is usually transient and is managed by enteral feeds, high glucose-containing intravenous fluids and medications like diazoxide. We describe a case of an infant with genetically proven Beckwith-Wiedemann syndrome with prolonged hyperinsulinemic hypoglycaemia. Despite treatment with high glucose-containing intravenous fluids, diazoxide and octreotide, her hypoglycaemia persisted. In addition to this, she also developed features of intestinal obstruction, which further complicated the management of hypoglycaemia. She underwent a rectal biopsy for this, which was highly suggestive of Hirschprung's disease. Following surgery, her abdominal distension and feed intolerance were settled and sugar control was improved. We present a rare association of Hirschsprung's disease with Beckwith-Wiedemann syndrome. To the best of our knowledge, this association has not been previously reported and this added to the difficulty in managing hyperinsulinemic hypoglycaemia in our patient.

Parental Education, Children's Nutritional Status and Non-verbal Intelligence in Rural School-children.

OBJECTIVE: To assess non-verbal intelligence and its relationship with nutritional status, nutrient intakes and parents' education in school-children. METHODS: A cross-sectional, observational study was conducted in children between 6-11 years, without any known chronic disorder or intellectual disability. Data were collected regarding parents' education, anthropometry and dietary intakes. Non-verbal intelligence was assessed by Raven's Coloured Progressive Matrices (RCPM). RESULTS: In 323 enrolled children (52.9% boys), a significant positive association was observed between RCPM scores and parents' education (father's rs=0.14, mother's rs=0.22), height Z-scores (rs=0.14) and dietary intakes of zinc (rs=0.14), iron (rs=0.12) and folate (rs=0.14). CONCLUSIONS: Height in normal range, higher zinc, iron and folate intakes, and parental higher educational levels were associated with higher non-verbal intelligence scores.

Long-term Growth in Congenital Adrenal Hyperplasia.

OBJECTIVES: To retrospectively assess growth of children with congenital adrenal hyperplasia (CAH) with special reference to puberty and to assess longitudinal growth and final height of subset of children with CAH. METHODS: A retrospective analysis of 30 children (14 boys) with classic CAH (11 salt wasters, 19 simple virilisers) followed up for a mean duration of 9.9 ± 2.4 y (Study period December 2002 through December 2016) was performed. Height Z scores, target height Z scores, height velocities and laboratory parameters were analysed. RESULTS: Children were treated with hydrocortisone in a mean dose of 15.7 ± 3.3 mg/m2/d. Mean 17-hydroxy progesterone in boys and girls were 10.8 ± 6.7 ng/ml and 11.3 ± 9.3 ng/ml respectively. Fifteen children (7 boys) developed central precocious puberty at mean age of 7.6 ± 1.8 y and 13 were treated with GnRH analogues for 3.5 y. Of all patients, 18 (10 girls, 8 boys) reached final height at a mean age of 14.2 ± 1.6 y. Mean final height achieved was 158.0 ± 8.5 cm in boys [target height (TH) -165.5 ± 3.8 cm] and in girls it was 149.9 ± 6.7 cm [target height (TH) 154.7 ± 6.4 cm]. Final height standard deviation scores (SDS) for boys and girls were - 2.06 ± 1.1 (TH-SDS -1.06 ± 0.5) and - 1.47 ± 1.1 (TH-SDS -0.56 ± 1.2) respectively and were not significantly different from target height Z scores (p > 0.05). Growth velocity was attenuated during pubertal years. CONCLUSIONS: Monitoring growth and puberty in children with CAH is critical for optimizing final height.

Effect of Antioxidant Supplementation on Total Antioxidant Status in Indian Children with Type 1 Diabetes.

Hyperglycemia results in the overproduction of free oxygen radicals that impair the endogenous antioxidant defenses. A randomized controlled trial was conducted to compare the effect of 3 months of antioxidant supplementation in the form of foods rich in micronutrients with pharmacological supplement on total antioxidant status of Indian children with type 1 diabetes. Ninety children with diabetes (mean age 11.5 ± 3.6 yrs, 37 boys) were randomly allocated to three groups: Group 1 (n = 31) = DM controls; Group 2 (n = 30) = multimicronutrient syrup; and Group 3 (n = 29) = dietary supplements (nine snack recipes rich in micronutrients). They received intervention for 3 months. Healthy controls were enrolled from local schools. Fasting blood was tested for total antioxidant status (TAS) and glycosylated hemoglobin (HbA1C). Children with diabetes had lower TAS (0.70 ± 0.2 vs. 1 ± 0.24 mmol/l, p = .0001) compared to healthy controls. Anthropometric and biochemical parameters were similar at baseline for all groups of diabetic children. Group 1 showed significant deterioration in TAS at endline (0.72 ± 0.16 vs. 0.60 ± 0.17 mmol/l, p = .008). Increase in TAS recorded in Group 2 was from 0.66 ± 0.21 to 0.70 ± 0.16 mmol/l and in Group 3 was from 0.68 to 0.73 mmol/l. There was a significant difference between Group 1 and Group 3 for percentage change in TAS (-13% vs. 16%, p = .035). Postsupplementation there was an increase in TAS values in children with diabetes, but they were still lower than in healthy controls. Indian diabetic children have compromised antioxidant status, which may be improved by incorporation of multimicronutrient-rich recipes in their diets.

Height-specific blood pressure cutoffs for screening elevated and high blood pressure in children and adolescents: an International Study.

Pediatric blood pressure (BP) reference tables are generally based on sex, age, and height and tend to be cumbersome to use in routine clinical practice. In this study, we aimed to develop a new, height-specific simple BP table according to the international child BP reference table based on sex, age and height and to evaluate its performance using international data. We validated the simple table in a derivation cohort that included 58,899 children and adolescents aged 6-17 years from surveys in 7 countries (China, India, Iran, Korea, Poland, Tunisia, and the United States) and in a validation cohort that included 70,072 participants from three other surveys (China, Poland and Seychelles). The BP cutoff values for the simple table were calculated for eight height categories for both the 90th ("elevated BP") and 95th ("high BP") percentiles of BP. The simple table had a high performance to predict high BP compared to the reference table, with high values (boys/girls) of area under the curve (0.94/0.91), sensitivity (88.5%/82.9%), specificity (99.3%/99.7%), positive predictive values (93.9%/97.3%), and negative predictive values (98.5%/97.8%) in the pooled data from 10 studies. The simple table performed similarly well for predicting elevated BP. A simple table based on height only predicts elevated BP and high BP in children and adolescents nearly as well as the international table based on sex, age, and height. This has important implications for simplifying the detection of pediatric high BP in clinical practice.

Knowledge of nutrition and physical activity in apparently healthy Indian adults.

OBJECTIVE: To assess knowledge of nutrition and physical activity; examine associations of knowledge with sociodemographic and anthropometric parameters; and evaluate the relationship between knowledge and practice in adults. DESIGN: In a cross-sectional design, 720 adults were selected using random sampling. Data on anthropometry, body fat, diet, physical activity, and nutrition and physical activity knowledge were collected using standardized questionnaires. Tertiles were used to categorize nutrition knowledge (NK) and physical activity knowledge (PK).SettingsSubjects selected through routine health checks from hospitals, housing societies and residential areas. SUBJECTS: A total of 720 adults (361 men) aged 35-50 years participated. RESULTS: Mean age was 42·7 (sd 9·4) years and mean BMI was 25·8 (sd 5·0) kg/m2. Mean energy intake was 64 %, protein was 68 % and fat was 144 % of the RDA. Mean NK and PK scores were 10·2 (sd 2·9) and 6·5 (sd 1·7), respectively, and were similar across genders (P>0·05). Individuals with higher education exhibited significantly higher NK and PK. Individuals with high fat had significantly higher NK and PK (P<0·05) than participants with normal fat percentage. Overweight and obese individuals had significantly higher PK (P<0·05). Multivariate regression modelling indicated that NK was positively associated with dietary intakes of leafy vegetables, salads and sprouts but negatively associated with fruit intake. BMI, television and reading time were positively associated with PK, even after adjusting for sociodemographic status. CONCLUSIONS: There is a need for increased efforts towards developing health education programmes focusing on transforming nutrition and physical activity knowledge into practice and adherence to guidelines.

Impact of dietary nutrient intake and physical activity on body composition and growth in Indian children.

BackgroundTo investigate interrelationships of dietary composition and physical activity (PA) with growth and body composition (BC) in urban Indian school children.MethodsA cross-sectional study was performed in 4,747 Indian school children (2,623 boys) aged 3-18 years. Weight, height, BC by body impedance analyzer, PA and dietary food intakes by questionnaire method were recorded.ResultsMean daily energy and protein intakes as recommended dietary allowance were significantly lower in both boys and girls (P<0.01) above 6 years, with 55% reduction in micronutrient intakes in older children. When compared with World Health Organization references, lower heights in pubertal boys and girls were related to dietary energy and protein intake. Multiple regression analysis showed positive association of height for age z-scores (HAZ) with midparental height z-scores (ß=0.45, P=0.0001) and protein density (ß=0.103, P=0.014). HAZ was negatively associated with inactivity (ß=-0.0001, P=0.049) in boys and girls (R2=0.104, P<0.01). Further, body fat percentage was negatively correlated with moderate or light activity and antioxidant intakes (P<0.01) but not with dietary fat intake. Percentage muscle mass was positively correlated with moderate activity and negatively with inactivity (P<0.05).ConclusionAdequacy of protein and antioxidant intakes, reducing inactivity and increasing moderate activity are essential for optimal growth and body composition in Indian children.

Screening score for early detection of cardio-metabolic risk in Indian adults.

OBJECTIVES: To develop and to evaluate efficacy of screening score for early detection of cardio-metabolic risk (CMR) in adults. METHODS: Cross-sectional data on anthropometry, lipids, sugar levels, diet, and physical activity were collected on 720 adults (361 men, 35-50 year) using standardized techniques. Screening score was developed using regression analysis-cluster of risk conditions (blood pressure, lipids, and sugar levels) was dependent variable against age, sex, waist, diet, and physical activity as independent variables. Odd ratios were added to obtain final score and receiver-operating characteristic (ROC) curves were constructed to identify cut-off value of CMR score. RESULTS: Mean age and BMI were 42.7 ± 9.4 years and 25.7 ± 5.0 kg/m2. Analysis showed age, male sex, waist, lack of fruits, green leafy vegetables, and lack of physical activity were independent predictors for increased CMR (p < 0.05). Total score ranged from 0 to 20. Area under the curve for ROC was 0.728 [95% (CI) 0.67-0.78]. Criterion value >8 had sensitivity (76%) and specificity (56%) for screening cases with CMR. CONCLUSIONS: Screening score is a pragmatic way of identifying individuals with CMR without performing biochemical tests. Cost-effective community screening programs may be planned.

Performance of Eleven Simplified Methods for the Identification of Elevated Blood Pressure in Children and Adolescents.

The identification of elevated blood pressure (BP) in children and adolescents relies on complex percentile tables. The present study compares the performance of 11 simplified methods for assessing elevated or high BP in children and adolescents using individual-level data from 7 countries. Data on BP were available for a total of 58 899 children and adolescents aged 6 to 17 years from 7 national surveys in China, India, Iran, Korea, Poland, Tunisia, and the United States. Performance of the simplified methods for screening elevated or high BP was assessed with receiver operating characteristic curve (area under the curve), sensitivity, specificity, positive predictive value, and negative predictive value. When pooling individual data from the 7 countries, all 11 simplified methods performed well in screening high BP, with high area under the curve values (0.84-0.98), high sensitivity (0.69-1.00), high specificity (0.87-1.00), and high negative predictive values (≥0.98). However, positive predictive value was low for most simplified methods, but reached ≈0.90 for each of the 3 methods, including sex- and age-specific BP references (at the 95th percentile of height), the formula for BP references (at the 95th percentile of height), and the simplified method relying on a child's absolute height. These findings were found independently of sex, age, and geographical location. Similar results were found for simplified methods for screening elevated BP. In conclusion, all 11 simplified methods performed well for identifying high or elevated BP in children and adolescents, but 3 methods performed best and may be most useful for screening purposes.
