And Function

Early-life conditions influence organ growth patterns and their functions, as well as subsequent risk for non-communicable chronic diseases in later life. A limited number of studies have determined that in Bangladesh, kidney size relates to its function among children as a consequence of the maternal and postnatal conditions. The present study objectives were to determine early-life conditions in relation to childhood kidney size and to compare their influences on kidney function. The study was embedded in a population-based prospective cohort of 1067 full-term singleton live births followed from fetal life onward. Kidney volume was measured by ultrasound in children at the age of 4.5 years (range 45–64 months), and the estimated glomerular filtration rate (eGFR) was assessed at the age of 9 years (range 96–116 months). The mean (s.d.) kidney volume of children at 4.5 years was 64.2 (11.3) cm3, with a significant mean difference observed between low birth weight and normal birth weight children (P<0.001). The multivariable model showed, changes in status from low birth weight to normal birth weight children, with kidney volume increases of 2.92 cm3/m2, after adjusting for the child’s age, sex, maternal age and early pregnancy body mass index, and socio-economic index variables. One-unit change in kidney volume (cm3/m2) improved the eGFR to 0.18 ml/min/1.73 m2. The eGFR in low birth weight children was 5.44 ml/min/1.73 m2 less than that in normal birth weight children after adjustments. Low birth weight leads to adverse effects on kidney size and function in children.

Abstract Background and Aims Low birth weight is associated with increased risk of kidney disease due to lower nephron endowment leading to hyperfiltration and subsequent nephron loss. Nephron number is thought to associate with kidney size. We compared kidney size measured by magnetic resonance imaging (MRI) with ultrasonography and measured glomerular filtration rate (mGFR) in adults with normal versus low birth weight. Method Healthy individuals aged 42-52 years with Low birth weight (LBW – 1100-2300g) and normal birth weight (NBW - 3500-4000g) were invited. GFR was measured using plasma clearance of iohexol. Kidney volume was measured on MRI images using axial T2 images and coronal T1 images with fat saturation without contrast enhancement, calculations were performed according to the ellipsoid formula - π/6 x Length x Width x Depth. Ultrasonographic imaging was done using a dorsal approach. In the maximal longitudinal view the parenchymal area was calculated subtracting the area of a manual tracing around the renal pelvis from the area of a manual tracing of the whole kidney. Volume and area from the two kidneys were added and total value was used for analyses. Kidney size measurements were compared between the two groups of LBW vs NBW, and analysis using Pearson’s correlation coefficient R between kidney volume and measured GFR and parenchymal area was performed. Results We included 102 individuals (54 LBW, 48 NBW). Total kidney volume was 302 ± 51 ml for female NBW vs 258 ± 48 ml for female LBW (p=0.002). For men, total kidney volume was 347 ± 51 ml vs 340 ± 65 ml (p=0.7). Measured GFR was significantly associated with kidney volume with R=0.52 (p&lt;0.001) for women and R=0.39 (p=0.007) for men. Kidney parenchymal area measurements using ultrasonography showed similar results with an R=0.77 between the MRI and the ultrasonography measurement and similar differences for sex and birth weight were seen. Conclusion Healthy middle-aged females born with LBW have smaller kidneys than healthy middle-aged females born with NBW, no difference were seen for males. Kidney volume associate with measured GFR.

Objective: The objective of this study was to evaluate the serum levels of various antioxidants, namely, vitamin A and E, superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPx) in the cord blood of term low birth weight (LBW) neonates who required delivery room resuscitation (DRR). Materials and Methods: This case control study included 37 term LBW neonates who needed DRR as cases and 44 term neonates as controls (15 term LBW and 29 term normal birth weight) who did not require resuscitation at birth. Neonates suffering from major congenital malformations, infection, or hemolytic disease were excluded. Standard methods were used to measure the levels of vitamin A, vitamin E, SOD, catalase, and GPx levels in the cord blood. Results: Vitamin A and E levels were significantly low in cases compared to term LBW controls as well as term normal birth weight controls. Levels of SOD, GPx, and catalase were comparable in different study groups. Conclusion: Our study shows that term LBW neonates requiring DRR had significantly low levels of vitamin A and E in their cord blood. This might compromise their ability to tolerate oxidative stress during DRR.

Over one half of the deaths from all congenital malformations were due to congenital cardiovascular disease. There were 496 individuals who died of congenital cardiovascular disease in Oregon during 1957 thru 1961, and three fourths of the deaths occurred in infants under 1 year of age. More males were affected by congenital cardiovascular disease than females, but, when congenital cardiovascular disease was present, the length of survival, as measured by life span, did not differ by sex. One out of every four infants dying of congenital cardiovascular disease was of low birth weight; of these, 60% were over 37 weeks' gestation. However, there was no difference in the life span of low birth weight and normal birth weight infants who died with congenital cardiovascular disease. This would imply that the significant factor of death in these infants was the cardiac malformation rather than the low birth weight. One out of every three infants who died with congenital cardiovascular disease had malformations of other systems. Fewer deaths than expected were identified among first born. Fetal deaths were noted more frequently in the population of mothers of children with congenital heart disease than in the overall population. The parental age in this group was significantly higher than in the general population and death rates of infants with congenital cardiovascular disease increased with advancing parental age. Thirty-two percent of the infants who died with congenital cardiovascular disease had single lesions. Early diagnosis and treatment is to be stressed if mortality is to be reduced.

Background Low birth weight (LBW) has long been used as an indicator of public health. Low birth weight is not a proxy for any dimension of other maternal or perinatal health outcomes. Low birth weight infants require special care, and have more chronic conditions, learning delays, and attention deficit hyperactivity disorders compared to infants of normal birth weight (NBW). Social competence is viewed as a primary component of healthy function and development and is an important predictor of academic and financial success.Objective To examine social competence of children aged 3-5 years born with low birth weight.Methods This cross-sectional study was undertaken in Palembang in 2012. Subjects consisted of children aged 3-5 years attended a preschool in the Seberang Ulu I District, Palembang, and were divided into two groups: low birth weight (LBW) and normal birth weight (NBW). Social competence was assessed by observation and Interaction Rating Scale (IRS) and Parenting Style questionnaire (PSQ). Chi-square analysis was used to compare social competence between the two groups. Multivariate regression logistic analysis was used to assess for the dominant factors that may affect a child’s social competence.Results Low birth weight children aged 3 to 5 years had a 1.435 times higher risk of low social competence compared to normal birth weight children of similar age. (RP 1.435; 95%CI 1.372 to 13.507; P=0.019). Multivariate regression logistic analysis revealed that parenting style was a dominant factor affecting social competence.Conclusion Social competence in 3 to 5-year-old children born with low birth weight is lower compared to those with normal birth weight.
