“…For each gender, height, weight, BMI, MPH, IGF-1 and IGFBP-3 were transformed to SDSs by using Turkish reference data according to age in 1 year interval (Neyzi et al, 1973; Growth, IGF-I, IGFBP-3 levels and economic status S Turan et al Bereket et al, 2006;Bundak et al, 2006). The effect of economic status (ES) on height SDS, weight SDS, BMI SDS, MPH SDS, IGF-1 SDS and IGFBP-3 SDS was analyzed by oneway ANOVA.…”

Objectives: The effect of economic status (ES) on growth, insulin-like growth factor (IGF)-I and IGF-binding protein (IGFBP)-3 in healthy children is not well characterized. We aimed to study the interrelationship between height, weight, IGF-I, IGFBP-3, mid-parental height (MPH) and ES. Design/subjects: Eight hundred and fourteen healthy children (428 boys, 386 girls; age 3-18 years) were classified according to income of the families as low, middle and high. Standard deviation scores (SDSs) of height, weight, MPH, IGF-I and IGFBP-3 were compared between the groups. The combined effect of these parameters and ES on height SDS was investigated with complex statistical models. Results: There was a significant trend for height and weight SDSs to increase with higher income levels in boys, but not in girls. Body mass index (BMI) SDSs were similar in three groups. There was a general trend for MPH SDS to increase with income levels in both sexes. In boys, IGF-I SDS was significantly higher in high ES group than low ES. In girls, IGFBP-3 SDSs were significantly higher in high ES group than in middle ES group. For both genders, height SDS was highly correlated with weight SDS and moderately correlated with BMI SDS, MPH SDS and IGF-1 SDS. All correlations were significant and positive. Complex models showed that MPH (19%), IGF-I (13%) and ES (3%) in boys, and MPH (16%) and IGF-I (7%) in girls have significant contribution to height SDSs. Conclusions: ES per se, independent of overt malnutrition, affects height, weight, IGF-I and IGFBP-3 with some gender differences in healthy children. Influence of income on height and weight show sexual dimorphism, a slight but significant effect is observed only in boys. MPH is the most prominent variable effecting height in healthy children. Higher height and MPH SDSs observed in higher income groups suggest that secular trend in growth still exists, at least in boys, in a country of favorable economic development.

Background: Deficiency of vitamin D leads to mal skeletal growth in children; moreover it is becoming an epidemic throughout the world. Decrease level of vitamin D can cause diverse of skeletal disorders in children like rickets, osteopenia etc. The relationship of vitamin D, obesity and insulin resistance is still not clear in the literature. Vitamin D deficiency may induce the altered glucose tolerance in obese children. Therefore the present study was designed to investigate the relationship of vitamin D and insulin resistance in obese children. Methods: The present study was a cross sectional type of study which was conducted in paediatric department of TMMC & RC, Moradabad. This study included 120 obese children (60 males and 60 females) of mean age 12 ± 2.6 years in group I. Control group II contained 100 healthy none obese children (50 males and 50 females) of 12.2 ± 1.8 years. Insulin resistance was calculated from fasting plasma measurements using HOMA-IR (insulin (mU/L) × glucose (mmol/l)/22.5). Insulin resistance criteria were HOMA-IR >2.5 for children. Vitamin D was measured by ELISA method (kit manufactured by Cayman chemical company, Ann Arbor, USA). Results: There was an insignificant difference in the FBG (>0.05) of group I obese children and group II control. Insulin (<0.05) and HOMA-IR (<0.01) were significantly low in obese children in comparison of none-obese children. Vitamin D (<0.01) was significantly lower in obese children compare to healthy children. vitamin D was negatively correlated with BMI (r = -0.42, r2 =0.1764, p<0.05) in obese children. There was a negative correlation between vitamin D and insulin resistance (r = -0.52, r2 =0.2704, p<0.05) in obese children. Conclusion: Present study suggests that there was strong relation between insulin resistance and obesity. Vitamin D was negatively correlated with BMI and insulin resistance. These findings strongly suggest vitamin D level may found insufficient or deficient in obese children. Therefore, obese children should be screened for vitamin D deficiency for their normal skeletal growth.

“…The body mass index (BMI) was evaluated based on percentile curves of Turkish children and obesity was defined as BMI higher than 95th percentile. 15 The mean BMI of the patients was 19.61 ± 3.52. Hypertension was defined as systolic and/or diastolic blood pressure to be higher than the 95th percentile for age and gender.…”

Insidious progressive renal damage caused by type 1 diabetes mellitus (T1DM) begins in childhood before it becomes manifest in adult ages. Heat shock proteins (HSPs) regulate the cell response to any hazardous factors to prevent cell structure. The aim of the study is to determine whether urine levels of HSPs increase in diabetic children with time and indicate a progressive renal injury in T1DM. Thirty-three patients with T1DM and 24 healthy children were enrolled in the study. Renal function was normal in all patients. Urine levels of HSP27, HSP40, HSP60, HSP70, and HSP90 were measured by enzyme-linked immunosorbent assay at two consecutive years (2012 and 2013). The results were evaluated as urine HSP/creatinine ratios (uHSP/Cr). Mean urine HSP27/Cr, HSP40/Cr, HSP60/Cr, HSP70/Cr, HSP90/Cr in patient group were significantly higher than in controls in 2012 (uHSP27/Cr 460.12 ± 217.64 versus 270.02 ± 136.83 pg/mgCr; uHSP40/Cr 180.89 ± 118.59 versus 99.44 ± 62.49 pg/mgCr; uHSP60/Cr 114.40 ± 64.91 versus 70.50 ± 43.70 pg/mgCr; uHSP70/Cr 41.17 ± 28.42 versus 16.47 ± 7.32 pg/mgCr; uHSP90/Cr 175.64 ± 102.22 versus 107.61 ± 75.85 pg/ mgCr) (p50.05). In 2013, uHSP70/Cr level increased significantly (51.08 ± 27.72 pg/mgCr; p ¼ 0.001), whereas uHSP60/Cr level decreased and uHSP27/Cr, uHSP40/Cr, uHSP90/Cr levels remained stable (p40.05). Area under the curve (AUC) for uHSP70/Cr (0.957) was significantly higher than the others. Using a cutoff 22.59 pg/mgCr for uHSP70/Cr to predict of diabetic damage, sensitivity and specificity were 85% and 96%, respectively. Our results suggest that uHSP70/Cr increases over time and may indicate early phases of progressive kidney damage in diabetic children. ARTICLE HISTORY
