“…This study showed that the risk of intrauterine growth restriction increased with increasing socioeconomic disadvantage. A similar conclusion was drawn by Beard JR et al [4] in their study which stated that socioeconomic disadvantage remains one of the dominant determinants of SGA.…”

Objectives The present study was conducted to compare the gravidogram and ultrasound in the detection of intrauterine growth restriction. Methods This study was conducted in the Department of Obstetrics and Gynecology, Voluntary Health Services, Chennai (TN) from August 2007-May 2009. The study included 321 women with singleton pregnancy in a longitudinal lie. These women underwent serial symphysiofundal height measurements and ultrasound. Birth weights of the newborns were noted at the time of delivery. Gravidogram and ultrasound findings were correlated with the birth weights. Results The sensitivity of the ultrasound in the detection of IUGR was higher (85.2 vs 74.1 %) than the gravidogram, but the specificity was almost the same (96.6 and 95.9 %). Conclusions The gravidogram is a simple and inexpensive screening tool and as useful as an ultrasound in detection of intrauterine growth restriction. Both gravidogram and ultrasound, when used together, have higher detection rates.

“…Several rodent studies have demonstrated significant changes in fetal body and brain composition, often in the absence of major reduction of birth weight following poor maternal nutrition during pregnancy (11,12). In relation to the changes in brain development that we report here in a nonhuman primate species, evidence is accumulating that birth weight at the lower end of the normal range is associated with impaired higher mental function in later life (5,13,14).We addressed effects of 30% global moderate MNR on early fetal cerebral development in a well-established nonhuman primate model, the fetal baboon. This degree of dietary reduction has beneficial effects on aging and life span in nonhuman primates (15) but may have adverse effects on brain development.…”

“…Recently, one study has shown that most women do not improve their dietary and lifestyle patterns in pregnancy (3). Decreased nutrient delivery to the fetus also occurs in teenage pregnancy (4) and during pregnancy in women over 35 y of age (5). Severe global reduction in nutrition during pregnancy has long been known to result in fetal growth restriction and to cause permanent brain dysfunction, especially cognitive and behavior deficits (6)(7)(8)(9)(10).…”

Moderate maternal nutrient restriction during pregnancy occurs in both developing and developed countries. In addition to poverty, maternal dieting, teenage pregnancy, and uterine vascular problems in older mothers are causes of decreased fetal nutrition. We evaluated the impact of global 30% maternal nutrient reduction (MNR) on early fetal baboon brain maturation. MNR induced major cerebral developmental disturbances without fetal growth restriction or marked maternal weight reduction. Mechanisms evaluated included neurotrophic factor suppression, cell proliferation and cell death imbalance, impaired glial maturation and neuronal process formation, down-regulation of gene ontological pathways and related gene products, and up-regulated transcription of cerebral catabolism. Contrary to the known benefits from this degree of dietary reduction on life span, MNR in pregnancy compromises structural fetal cerebral development, potentially having an impact on brain function throughout life.oderate malnutrition during pregnancy is widespread in both developing and industrialized countries. Worldwide, 852 million people experienced food insecurity in 2004 (1) and 35-40% of children experience moderate malnutrition (2). In industrialized countries, maternal lifestyle, in which dieting (including global food reduction) is used for cosmetic reasons, is a common cause of moderate malnutrition. Recently, one study has shown that most women do not improve their dietary and lifestyle patterns in pregnancy (3). Decreased nutrient delivery to the fetus also occurs in teenage pregnancy (4) and during pregnancy in women over 35 y of age (5). Severe global reduction in nutrition during pregnancy has long been known to result in fetal growth restriction and to cause permanent brain dysfunction, especially cognitive and behavior deficits (6-10). In rodents, these deficits are accompanied by alterations of neuronal excitability as well as structural changes in the developing and adult brain (11,12). In contrast, effects of moderate maternal global reduction in nutrition on the fetus have been poorly examined. It is often assumed that moderate degrees of maternal nutrient reduction (MNR) are without unwanted consequences because it has generally been considered that the mother prioritizes fetal nutrient supply at the expense of her own needs, and brain growth is assumed to be spared from the other fetal effects of moderate decreases in fetal nutrient availability. This concept no longer appears to be tenable. Several rodent studies have demonstrated significant changes in fetal body and brain composition, often in the absence of major reduction of birth weight following poor maternal nutrition during pregnancy (11,12). In relation to the changes in brain development that we report here in a nonhuman primate species, evidence is accumulating that birth weight at the lower end of the normal range is associated with impaired higher mental function in later life (5,13,14).We addressed effects of 30% global moderate MNR on early fetal cereb...

“…The variables found on the birth certificate data set, particularly tobacco use, were sufficient to explain all of the differences in SGA prevalence for mining counties with and without MTM mining activity and three-quarters of the difference among mining counties and non-mining counties. It may be that further inclusion of known risk factors for SGA, such as maternal height and weight [22] or socioeconomic disadvantage [23], might explain much of the remaining differences.…”

Objectives: To identify risk factors for small-for-gestational age (SGA) for counties in central Appalachian states (Kentucky (KY), Tennessee (TN), Virginia (VA), and West Virginia (WV)) with varied coal mining activities. Material and Methods: Live birth certificate files (1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002) were used for obtaining SGA prevalence rates for mothers based on the coal mining activities of their counties of residence, mountain-top mining (MTM) activities, underground mining activities but no mountain-top mining activity (non-MTM), or having no mining activities (non-mining). Co-variable information, including maternal tobacco use, was also obtained from the live birth certificate. Adjusted odds ratios were obtained using multivariable logistic regression comparing SGA prevalence rates for counties with coal mining activities to those
