Effects of Insulin on Gestational Pima Indian Heritage Females

Diabetes and obesity reach epidemic proportions all over the world, while the effects of insulin resistance and its consequences are gaining prominence. The article derives the effects of insulin on gestational Pima Indian heritage females with minimum 21 years old. It is identified herein that mean insulin level for gestational women (GW) is positively linked with glucose level (P=0.0055), while it is negatively linked with age (P=0.0095). Mean insulin level for GW is independent of pregnancies (P=0.1866) and diabetes pedigree function (DPF) (P=0.5321), while it is partially positively linked with their joint interaction effect Pregnancies*DPF (P=0.0864). It is positively linked with blood pressure (BP) (P<0.0001) and triceps skin-fold thickness (TST) (P<0.0001), while it is negatively linked with the joint interaction effects BP*TST (P<0.0001) and DPF*TST (P<0.0001). In addition, mean insulin level is negatively linked with body mass index (BMI) (P=0.0001), while it is positively partially linked with the interaction effect BMI*DPF (P=0.1312). Variance of insulin level is positively linked with pregnancies (P=0.0184) and age (P=0.0027), while it is negatively linked with their joint interaction effect Pregnancies*Age (P=0.0418). Also variance of insulin level is partially negatively linked with BMI (P=0.0738) and glucose level (P=0.1439), while it is partially positively linked with their joint interaction effect BMI*Glucose (P=0.1472). Further, variance of insulin level is negatively linked with DPF (P=0.0309). It is concluded that for GW, insulin level increases with the increase of glucose level, BP, TST, and the interaction effects Pregnancies*DPF & BMI*DPF, and it decreases with the increase age, BMI, and the interaction effects BP*TST & DPF*TST. GW should be careful on her glucose level, BMI, BP & TST.

Correlation of body mass index with biceps and triceps skin fold thickness

Background: Body mass index (BMI) and skin fold thickness are independently established methods of nutritional assessment. Present study tries to find out correlation between them.Methods: A cross sectional study was conducted in private medical college among 2nd year MBBS students. Total 24 students were sampled by purposive sampling method. After obtaining permission from Institutional Ethics committee and written informed consent from participants, study information was gathered using semi structured proforma. Anthropometric measurements were taken using standard techniques and equipments. Data was analysed using Microsoft Excel and Prism version 5.0 and appropriate tests were used considering normality of data.Results: Out of 24 study participants 14 were males and 10 were females. Mean weight was 59.29±12.59 kg, mean height was 164.77±10.28 cm, mean BMI was 21.68±3.18 kg/m2. Mean biceps skin fold thickness was 7.20±2.68 mm and mean triceps skin fold thickness was 10.75±3.33mm. Of all the participants 4 (16.67%) were having underweight BMI, 15 (62.50%) were having normal BMI, 5 (20.83%) were pre-obese. BMI correlated significantly with triceps skin fold thickness Spearman’s r=0.53, p=0.006 as compared to biceps skin fold thickness Spearman’s r=0.36, p=0.07 in complete sample. Among males BMI correlated significantly with triceps skin fold thickness Spearman’s r=0.64, p=0.01 as compared to biceps skin fold thickness.Conclusions: BMI correlates significantly with triceps skin fold thickness as compared to biceps skin fold thickness in general. Significant correlation between BMI and triceps skin fold thickness was found with males as compared to females.

Body fat indices for identifying risk of hypertension in Indian children

Background: Studies in India shown high body fat indices were strongly associated with hypertension in Indian children, but such studies mostly not done in southern states of India. So, authors include children in Tamilnadu measure body fat indices and blood pressure to find which body fat index correlates closely with hypertension.Methods: Standing height was measured using stadiometer. Weight was measured using electronic scale. WC measured in standing position, by a stretch resistant. WC above 90th centile will be considered as Adipose. Waist to height ratio optimal cut-off value is 0.44 for children. TSFT recorded using Harpenden caliper, on the non-dominant upper arm. Wrist circumference measured using stretch resistant tape.Results: In this study 2000 children were participated. More hypertensives are seen in 10 to 12 years(62) and 16 to 18 years(31).Increased weight correlated with hypertension. Study indicates waist circumference is significantly correlated with systolic BP p<0.003, diastolic BP p<0.000. This study shows significant correlation p<0.003 for systolic and p<0.000 for diastolic BP with triceps skin fold thickness estimation. In multivariate analysis with systolic blood pressure and diastolic blood pressure shows very strong correlation with waist circumference, waist to height ratio and triceps skin fold thickness.Conclusions: In this study we investigate the correlation between body fat indices and blood pressure correlation was statistically analyzed which shows that waist circumference, waist to height ratio and triceps skin fold thickness were strongly correlated with systolic and diastolic BP.

Are Changes in Distance-Run Performance of Australian Children between 1985 and 1997 Explained by Changes in Fatness?

The aim of this study was to determine whether changes in fitness performance could be explained by changes in body fatness. Two hundred seventy-nine 10- to 12-year-old children were tested in 1985 as part of a national survey. They were matched for age, sex, body-mass index, and triceps skin-fold thickness with 279 children from a 1997 survey. Average speeds on the 1.6 km walk/run test were compared. Children from the 1997 survey performed significantly worse than their matched peers from the 1985 survey. The decline in performance was evident for boys, girls, and all children. Matching for fatness reduced performance differences by about 61% in boys, and 37% in girls. Declines in fitness performance in this population have not been entirely due to increases in fatness.
