Development and Validation of a Nomogram-Based Prognostic Model to Predict High Blood Pressure in Children and Adolescents—Findings From 342,736 Individuals in China. Front Cardiovasc Med 2022; 9:884508. [PMID: 35811689 PMCID: PMC9260112 DOI: 10.3389/fcvm.2022.884508] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Accepted: 04/19/2022] [Indexed: 11/29/2022] Open
Abstract
Objectives Predicting the potential risk factors of high blood pressure (HBP) among children and adolescents is still a knowledge gap. Our study aimed to establish and validate a nomogram-based model for identifying youths at risk of developing HBP. Methods HBP was defined as systolic blood pressure or diastolic blood pressure above the 95th percentile, using age, gender, and height-specific cut-off points. Penalized regression with Lasso was used to identify the strongest predictors of HBP. Internal validation was conducted by a 5-fold cross-validation and bootstrapping approach. The predictive variables and the advanced nomogram plot were identified by conducting univariate and multivariate logistic regression analyses. A nomogram was constructed by a training group comprised of 239,546 (69.9%) participants and subsequently validated by an external group with 103,190 (30.1%) participants. Results Of 342,736 children and adolescents, 55,480 (16.2%) youths were identified with HBP with mean age 11.51 ± 1.45 years and 183,487 were boys (53.5%). Nine significant relevant predictors were identified including: age, gender, weight status, birth weight, breastfeeding, gestational hypertension, family history of obesity and hypertension, and physical activity. Acceptable discrimination [area under the receiver operating characteristic curve (AUC): 0.742 (development group), 0.740 (validation group)] and good calibration (Hosmer and Lemeshow statistics, P > 0.05) were observed in our models. An available web-based nomogram was built online on https://hbpnomogram.shinyapps.io/Dyn_Nomo_HBP/. Conclusions This model composed of age, gender, early life factors, family history of the disease, and lifestyle factors may predict the risk of HBP among youths, which has developed a promising nomogram that may aid in more accurately identifying HBP among youths in primary care.

Cord Blood Advanced Lipoprotein Testing Reveals an Interaction between Gestational Diabetes and Birth-Weight and Suggests a New Early Biomarker of Infant Obesity.

Abstract
Abnormal lipid metabolism is associated with gestational diabetes mellitus (GDM) and is observed in neonates with abnormal fetal growth. However, the underlying specific changes in the lipoprotein profile remain poorly understood. Thus, in the present study we used a novel nuclear magnetic resonance (NMR)-based approach to profile the umbilical cord serum lipoproteins. Two-dimensional diffusion-ordered 1H-NMR spectroscopy showed that size, lipid content, number and concentration of particles within their subclasses were similar between offspring born to control (n = 74) and GDM (n = 62) mothers. Subsequent data stratification according to newborn birth-weight categories, i.e., small (n = 39), appropriate (n = 50) or large (n = 49) for gestational age (SGA, AGA and LGA, respectively), showed an interaction between GDM and birth-weight categories for intermediate-density lipoproteins (IDL)-cholesterol content and IDL- and low-density lipoproteins (LDL)-triglyceride content, and the number of medium very low-density lipoproteins (VLDL) and LDL particles specifically in AGA neonates. Moreover, in a 2-year follow-up study, we observed that small LDL particles were independently associated with offspring obesity at 2 years (n = 103). Collectively, our data demonstrate that GDM disturbs triglyceride and cholesterol lipoprotein content across birth-weight categories, with AGA neonates born to GDM mothers displaying a profile more similar to that of adults with dyslipidemia. Furthermore, an altered fetal lipoprotein pattern was associated with the development of obesity at 2 years.

Post-weaning protein malnutrition induces myocardial dysfunction associated with oxidative stress and altered calcium handling proteins in adult rats. J Physiol Biochem 2021; 77:261-272.

Abstract
Hypercaloric low-protein diet may lead to a state of malnutrition found in the low-income population of Northeastern Brazil. Although malnutrition during critical periods in the early life is associated with cardiovascular diseases in adulthood, the mechanisms of cardiac dysfunction are still unclear. Here we studied the effects of post-weaning malnutrition due to low protein intake induced by a regional basic diet on the cardiac contractility of young adult rats. In vivo arterial hemodynamic and in vitro myocardial contractility were evaluated in 3-month-old rats. Additionally, protein content of the sarcoplasmic reticulum Ca(2+)-ATPase (SERCA), total phospholamban (PLB) and phosphorylated at serine 16 (p-Ser(16)-PLB), α2-subunit of the Na(+)/K(+)-ATPase (α2-NKA), and Na(+)/Ca(2+) exchanger (NXC) and in situ production of superoxide anion (O2(-)) were measured in the heart. Blood pressure and heart rate increased in the post-weaning malnourished (PWM) rats. Moreover, malnutrition decreased twitch force and inotropic responses of the isolated cardiac muscle. Protein expression of SERCA, PLB/SERCA, and p-Ser(16)-PLB/PLB ratios and α2-NKA were decreased without changing NCX. The contraction dependent on transsarcolemmal calcium influx was unchanged but responsiveness to Ca(2+) and tetanic peak contractions were impaired in the PWM group. Myocardial O2(-) production was significantly increased by PWM. Our data demonstrated that this hypercaloric low-protein diet in rats is associated with myocardial dysfunction, altered expression of major calcium handling proteins, and increased local oxidative stress. These findings reinforce the attention needed for pediatric care, since chronic malnutrition in early life is related to increased cardiovascular risk in adulthood. Graphical Abstract.

Abstract
Background: Little is known about the long-term effects of early childhood undernutrition on adolescent cardiovascular disease risk and educational performance in low-income countries. We examined this in a rural Ugandan population. Objective: To investigate if stunting or wasting among children aged 2–5 years is associated with cardiovascular disease risk or educational achievement during adolescence. Methods: We conducted analyses using data from a cohort of children followed from early childhood to adolescence. Weight and height were measured in 1999–2000 when the children were 2–5 years of age and repeated in 2004/2005 and 2011. We compared cardiovascular disease risk parameters (mean blood pressure, lipids, HbA1c) and schooling years achieved in 2011 among 1054 adolescents categorised into four groups: those who experienced stunting or wasting throughout follow-up; those who recovered from stunting or wasting; those who were normal but later became stunted or wasted; and those who never experienced stunting or wasting from childhood up to adolescence. We controlled for possible confounding using multiple generalised linear regression models along with Generalised Estimating Equations to account for clustering of children within households. Results: Wasting was negatively associated with systolic blood pressure (−7.90 95%CI [−14.52,-1.28], p = 0.02) and diastolic blood pressure (−3.92, 95%CI [−7.42, −0.38], p = 0.03). Stunting had borderline negative association with systolic blood pressure (−2.90, 95%CI [−6.41, 0.61] p = 0.10). Recovery from wasting was positively associated with diastolic blood pressure (1.93, 95%CI [0.11, 3.74] p = 0.04). Stunting or wasting was associated with fewer schooling years. Conclusion: Recovery from wasting rather than just an episode in early childhood is associated with a rise in blood pressure while educational achievement is compromised regardless of whether recovery from undernutrition happens. These findings are relevant to children exposed to undernutrition in low-income settings.

Abstract
Several studies have reported association of altered levels of lipids and some trace elements with risk factors for cardiovascular disease development in adulthood. Accordingly, the present study aimed to determine the relationship among the serum levels of copper (Cu), zinc (Zn), lipids, lipoproteins and apolipoproteins in preterm infants through an assessment of atherogenic indices shortly after birth. Blood samples were collected within 20 min of birth from 45 preterm infants with gestational ages ranging from 32 to 35 weeks. Serum Cu, Zn, total cholesterol (TC), low-density lipoprotein cholesterol (LDLc), high-density lipoprotein cholesterol (HDLc), apolipoprotein-A1 (apoA1) and apolipoprotein-B (apoB) levels were measured, and the TC/HDLc, LDLc/HDLc and apoB/apoA1 ratios were calculated. Upon determining the correlation between the levels of Cu, Zn and these indices of lipid metabolism, triglyceride (TG) and Cu were found to correlate negatively with birth weight (BW) and the standard deviation (s.d.) score for body weight. Furthermore, Cu levels correlated positively with the TG level and TC/HDLc, LDLc/HDLc and apoB/apoA1 ratios and negatively with the HDLc level and HDLc/apoA1 ratios. However, a stepwise multiple regression analysis indicated that the s.d. score for BW and TG level were significant independent determinants of the Cu level. In contrast, Zn did not correlate with any of these indices. In conclusion, intrauterine growth restriction and the TG level at birth influence Cu levels in preterm infants, whereas atherogenic indices do not affect this parameter.

Abstract
BACKGROUND This study was performed to determine the blood pressure (BP) percentile curves by height, as well as to assess the prevalence of high BP and its influencing factors among children in the first national survey in this field in Iran. DESIGN A multicentre national cross-sectional survey. METHODS This study was performed in 23 provinces among a representative sample of 21,111 students aged 6-18 years. RESULTS Age and sex-specific percentile curves of systolic and diastolic BP were obtained by height. A comparison of the values obtained corresponding to the 90th percentiles with the Second Task Force cut-offs showed that the BP values and trends were relatively similar in both studies. The overall prevalence of systolic, diastolic as well as systolic or diastolic hypertension according to the Second Task Force study 95th percentile cut-off points were 4.2, 5.4 and 7.7%, respectively, without a significant sex difference. A history of low birthweight, overweight, taller height, the consumption of solid hydrogenated fat, as well as the frequency of fast food consumption increased the risk of both systolic and diastolic hypertension. Male sex, large waist, and low education of the mother were the risks for systolic hypertension, whereas the risk of diastolic hypertension rose with living in an urban area, attending public school, low physical activity level, having a housewife mother, and a positive family history of obesity, especially in the parents. CONCLUSION Considering the effect of modifiable environmental factors on the childrens' BP, encouraging breast feeding and a healthy lifestyle may have an important effect on public health.

Abstract
BACKGROUND Pre-school age is important for developing healthy attitudes towards physical activity (PA). However, research on pre-schoolers' pedometer-determined PA is limited. AIM To describe pre-schoolers' ambulatory activity; investigate step count differences in respect to Body Mass Index (BMI) categories and examine the prevalence of obesity. SUBJECTS AND METHODS Pre-school aged children (n = 250; 5.5 ± 0.4 years) from Komotini (Greece) wore Omron HJ-720IT-E2 pedometers for 10 consecutive days. Height and weight were measured and BMI was calculated. RESULTS Three-way repeated measures ANOVAs revealed that children performed more steps on weekdays than during weekends (p < 0.001) and during leisure time than school (p < 0.001). Significant differences appeared between normal and obese children's counts on weekdays (p < 0.001), weekend days (p < 0.05), during school (p < 0.001), after school (p < 0.005) and in weekly steps (p < 0.005). No gender differences were detected. Moreover, according to a sample t-test analysis, children's daily steps were significantly different from the 10,000 steps/day guideline, while obesity prevalence was 15.6%. CONCLUSION School-based ambulatory activity is lower than after school ambulatory activity, independent of BMI-category and gender, although obese children demonstrated fewer steps. Taking into account the high rate of both the obesity prevalence and children not meeting the 10,000 steps/day guideline, the need for preventive policies becomes obvious.

Abstract
AIM The intra-uterine environment affects the risk of development of cardiovascular disease in adulthood. The aim of this study was to determine the influence of prematurity and foetal growth restriction on lipid metabolism, by assessing atherogenic indices soon after birth in preterm infants. METHODS Blood samples were collected within 20 min of birth from 80 preterm infants with a gestational age of ≤35 weeks. Serum total cholesterol (TC), low-density lipoprotein cholesterol (LDLc), high-density lipoprotein cholesterol (HDLc), apolipoprotein-A1 (apoA1) and apolipoprotein-B (apoB) levels were measured. The ratio of TC/HDLc, LDLc/HDLc and apoB/apoA1 were also calculated. Correlations between these indices and gestational age, birth weight and the standard deviation (SD) score for birth weight were also determined. RESULTS Gestational age, birth weight and SD score for birth weight were negatively correlated with the TC/HDLc, LDLc/HDLc and apoB/apoA1 ratios. CONCLUSION In preterm infants, prematurity and poor foetal growth may influence lipid and apolipoprotein metabolism and affect atherogenic indices at birth.

Abstract
BACKGROUND Cardiovascular disease (CVD) affects 71 million American adults and remains the leading cause of death in the United States and Europe. Despite studies that suggest that the development of CVD may be linked to intrauterine growth or early events in childhood, little direct experimental evidence supports the notion. OBJECTIVE We investigated whether exposure to cigarette smoke in utero alters the risk of developing CVD later in life. METHODS We exposed B(6)C(3)F(1) mice (via whole-body inhalation) to either filtered air or mainstream cigarette smoke (MCS, at a particle concentration of 15 mg/m(3)) from gestational day 4 to parturition. Adult offspring were fed a normal chow diet or switched to a high-fat diet 2 weeks before sacrifice. We measured dam and offspring body weight, plasma lipid parameters, lipoprotein subclass particle numbers and sizes, and total antioxidant capacities. RESULTS Adult female mice prenatally exposed to MCS demonstrated significantly higher body weight and levels of plasma high-density lipoprotein (HDL) and low-density lipoprotein than did their air-exposed counterparts. When fed a high-fat diet for 2 weeks, males, but not females, exposed prenatally to MCS gained substantially more weight and exhibited dramatic alterations in total cholesterol and HDL levels compared with their air-exposed counterparts. CONCLUSIONS These data provide, for the first time, direct experimental evidence supporting the notion that prenatal exposure to cigarette smoke affects offspring weight gain and induces a lipid profile that could alter the offspring's risk of developing CVD later in life.

Abstract
The objective of this study was to determine the predictive factor of a combination of traditional and new risk factors for coronary heart diseases (CHDs) as well as the echocardiographic findings in children of parents suffering premature myocardial infarction in comparison with controls. Overall, 239 adolescents aged 12 to 18 years including 112 children of parents with premature CHD (<55 years) and 127 age- and sex-matched controls without such a family history. In addition to measuring anthropometric indexes and blood pressure, serum fasting blood sugar, lipid profile, C-reactive protein, Lpa, and oxidized LDL as well as carotid-intima media thickness and left ventricular mass were determined. Factor analysis showed that clusters of inflammatory factors and markers of oxidation as well as carotid-intima media thickness and left ventricular mass were correlated with each other and were associated with a positive parental history of premature CHD in youths. These findings complement the functional and structural changes in arteries of adults with a familial predisposition to CHD and underscore the importance of using a high-risk approach for primordial/primary prevention of CHD from early life and of considering the screening of children and siblings in the management of patients with premature CHD.

[PMID: 17935959 DOI: 10.1016/j.numecd.2007.02.014] [Citation(s) in RCA: 63] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2006] [Revised: 12/31/2006] [Accepted: 02/22/2007] [Indexed: 01/19/2023]
Abstract
BACKGROUND AND AIM To date, research on the influence of environmental factors on metabolic syndrome (MS) among youths is limited. This study was conducted to investigate for the first time the association of these factors with MS in a large national, representative sample of children from a non-Western population. METHODS AND RESULTS The study population comprised of 4811 students (2248 boys and 2563 girls) aged 6-18 years, living in six different provinces in Iran. MS, defined based on criteria analogous to those of the Adult Treatment Panel III, was detected in 14.1% of participants. A birth weight of >4000 g in boys and <2500 g in girls increased the risk of having the MS [OR, 95% CI: 1.4 (1.007, 2.05) and 1.2 (1.1, 1.4), respectively]. Poorly educated parents and a positive parental history of chronic disease were other risks factors associated with MS. Low levels of physical activity significantly increased the risk of having MS [boys: 1.3 (1.1, 1.7); girls: 1.4 (1.2, 1.6)]. The risk of MS increased in-line with the consumption of solid hydrogenated fat [boys: 1.2 (1.07, 1.3); girls, 1.3 (1.1, 1.5)] and bread made with white flour [boys: 1.6 (1.3, 2.1); girls, 1.4 (1.1, 1.7)]. In contrast, an increased frequency of consumption of fruits and vegetable, as well as dairy products decreased the risk of having MS. CONCLUSION Considering the effect of modifiable lifestyle habits and birth weight on MS in youths, urgent public health approaches should be directed towards primordial and primary prevention of this rapidly growing problem.

Abstract
The cord blood lipid profile may be associated with lifelong changes in the metabolic functions of the individual. The aim of the present study was for the first time in Iran to assess the cord blood lipid profile of neonates, as well as some of its environmental influencing factors. The subjects were 442 (218 boys and 224 girls) normal vaginal delivery newborns. Overall, 14.4% of neonates were preterm and the rest were full-term. In total, 9.2% (n = 35) of the full-term newborns were small-for-gestational-age (SGA), of which 16 had a ponderal index (PI) below the 10th percentile (SGA I) and 19 had a PI above the 10th percentile (SGA II), 5.5% (n = 21) were large-for-gestational-age (LGA), and the remainder were appropriate-for-gestational-age (AGA).Before becoming pregnant, 6.9% of mothers were underweight, 49.3% had normal body mass index (BMI), 39.4% were overweight and 4.4% were obese. Total and high-density lipoprotein cholesterol (HDL-C) in girls were significantly higher than in boys (80.3 +/- 33.3 and 31.1 +/- 9.9 vs. 73.3 +/- 23.1 and 28.8 +/- 8.7 mg/dL, respectively, P < 0.05). The mean apolipoprotein A (apoA) of neonates with underweight mothers was significantly lower, and the mean apoB level of those with overweight mothers was significantly higher than other neonates. The mean low-density lipoprotein cholesterol (LDL-C), HDL-C and apoA of the LGA newborns were significantly lower, and their apoB was significantly higher compared with AGA and SGA neonates. The SGA I neonates had significantly lower total cholesterol, LDL-C, HDL-C and apoA, as well as higher triglycerides, lipoprotein a and apoB than the SGA II group. The mean cord blood triglycerides of full-term neonates was significantly higher than preterm neonates (69.4 +/- 11.9 vs. 61.4 +/- 12.7 mg/dL, respectively, P = 0.04). A preconception maternal BMI of > or =25 kg/m(2) correlated significantly with the cord triglycerides (OR = 1.3, [95% CI 1.07, 1.5]) and with apoB (OR = 1.4, [95% CI 1.1, 1.5]). The BMI <18 of mothers before pregnancy correlated with low HDL-C (OR = 1.3, [95% CI 1.04, 1.7]). Birthweight correlated with high cord triglyceride level (SGA: OR = 1.4, [95% CI 1.1, 1.7]; LGA: OR = 1.6, [95% CI 1.3, 1.7] compared with AGA). These associations remained significant even after adjusting for the preconception BMI of mothers. Our findings reflect the possible interaction of environmental factors and fetal growth and the in utero lipid metabolism. Long-term longitudinal studies in different ethnicities would help to elucidate the relationship.

Abstract
The current study is a 4-year follow-up after the 6-year-long health and nutrition intervention programme applied in the primary schools of Crete. The aim of the current work was to identify whether the benefits obtained in certain health indices at the end of the intervention period were also present 4 years later. From a representative population of 441 pupils (250 from the intervention schools and 191 from the control schools), biochemical, dietary and physical activity data were obtained at baseline, at the end of the intervention period and after intervention (academic years 1992–1993, 1997–1998 and 2001–2002, respectively). The findings of the current study revealed that the favourable changes in serum lipids observed at the end of the intervention period were maintained from baseline to after intervention for total cholesterol (−24·3 (SE 1·65)V. −9·70 (SE 2·03) mg/dl;P=0·001), LDL-cholesterol (−18·6 (SE 1·41)V. −2·49 (SE 1·75) mg/dl;P<0·001), HDL-cholesterol (−8·34 (SE 0·75)V. −9·60 (SE 1·10) mg/dl;P=0·014) and total cholesterol:HDL-cholestrol ratio (0·31 (SE 0·06)V. 0·04 (SE 0·05);P=0·001). Similar favourable changes for the intervention group were observed in leisure-time physical activities (38·3 (SE 11·7)V. −13·2 (SE 10·9) min/week;P=0·038) and BMI (6·05 (SE 0·18)V. 6·67 (SE 0·21) kg/m2;P=0·014), whereas no changes were observed in the fitness and dietary indices examined. The findings of the current study are encouraging, indicating maintenance of the favourable changes observed in serum lipids, BMI and physical activity 4 years after the programme had ended

Is family history of premature cardiovascular diseases appropriate for detection of dyslipidemic children in population-based preventive medicine programs? CASPIAN study. Pediatr Cardiol 2006; 27:729-36. [PMID: 17111289 DOI: 10.1007/s00246-006-1391-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2006] [Accepted: 07/19/2006] [Indexed: 12/19/2022]
Abstract
The objectives of this study were to determine the prevalence of dyslipidemia and the usefulness of self-report family history (FH) of premature cardiovascular disease (CVD) for identifying children with lipid disorders. This study was conducted on a representative, population-based sample of 4811 Iranian children and adolescents (2248 boys and 2563 girls) aged 6-18 years. We compared the obtained serum lipid profile with that of the Lipid Research Clinic (LRC) and calculated the predictive value of FH for detecting those children with dyslipidemia.Overall, for both genders and for age groups, the mean serum triglycerides (TG) and its percentiles were significantly higher, and the mean and percentiles of total, low-density, and high-density cholesterol (TC, LDL-C, and HDL-C respectively) were significantly lower than the LRC values. In total, 45.7% of participants had dyslipidemia; the most frequent ones were low HDL-C (24.8%) and hypertriglyceridemia (24.5%), followed by hypercholesterolemia (6.4%) and high LDL-C (6.3%), respectively. The mean serum lipid levels and the anthropometric measures were not significantly different among those with or without positive FH. The sensitivity, and specificity, positive and negative predictive values for FH in detecting those children with dyslipidemia were 28.4, 70.3. 44.7, and 53.8%, respectively. The usefulness of FH in identifying dyslipidemic children was relatively low. The common lipid disorders in our community were the components of the metabolic syndrome. We suggest that the current guidelines for screening lipid disorders in youths, which are based on cholesterol, should consider such ethnic differences.

Abstract
BACKGROUND For the first time in Iran, and to the best of our knowledge in Asia, we assessed the anthropometric indices most closely correlated to cardiovascular disease (CVD) risk factors in a large nationally representative sample of children and adolescents to be used as a simple tool for identifying those at risk. METHODS This multi-center study was performed among a representative sample of 4811 school students (2248 boys and 2563 girls) aged 6-18 years, as part of the baseline survey of a national surveillance system. Anthropometric indices and CVD risk factors were measured using standard protocols, and their correlation was analyzed by using Receiver Operator Characteristic (ROC) curves and partial correlation. RESULTS The most prevalent CVD risk factors were low HDL-C (28%), followed by hypertriglyceridemia (20.1%), and overweight (17%). The ROC analyses showed that among boys, all anthropometric indices had the same association with CVD risk factors in 6-9.9-year-age group, while in the 10-13.9 and 14-18-year-age groups, respectively waist circumference (WC) and body mass index (BMI) were the best in distinguishing CVD risk factors. Among girls, these indices were respectively BMI and waist to stature ratio (WSR); WC and WSR; and WC. In the partial correlation analysis, in boys, the highest coefficient was found for BMI; BMI and WC; and for WC and WSR; in girls, these indices were BMI; WC and WSR; and BMI respectively. CONCLUSIONS In the present study, BMI, WC and WSR were the most appropriate in predicting CVD risk factors. It may be clinically useful in the pediatric population to routinely measure WC and WSR in addition to BMI as a screening tool to identify high-risk youth.

Abstract
OBJECTIVES To examine possible effects on blood pressure, neurological function, and neurobehavioral tests in school-aged children with and without prenatal pesticide exposure in an area where stunting is common. METHODS In a community of Northern Ecuador with intensive floriculture and a high female employment rate, we invited 79 children attending the 2 lowest grades of a public school for clinical examinations. In addition to a thorough physical examination, we administered simple reaction time, Santa Ana dexterity test, Stanford-Binet copying, and Wechsler Intelligence Scale for Children-Revised Digit Spans forward. Maternal interview included detailed assessment of occupational history to determine pesticide exposure during pregnancy. Recent and current pesticide exposure was assessed by erythrocyte acetylcholine esterase activity and urinary excretion of organophosphate metabolites. RESULTS All eligible children participated in the study, but 7 children were excluded from data analysis due to other disease or age >9 years. A total of 31 of the remaining 72 children were classified as stunted based on their height for age. Maternal occupational history revealed that 37 children had been exposed to pesticides during development. After confounder adjustment, prenatal pesticide exposure was associated with a higher systolic blood pressure than in the controls. On neurological examination, 14 exposed children and 9 controls showed > or =1 abnormalities. Of 5 neurobehavioral tests, the Stanford-Binet copying test showed a lower drawing score for copying designs in exposed children than in controls. Stunting was associated with a lower score on this test only, and both risk factors remained statistically significant in a multiple regression analysis with adjustment for demographic and social confounders. Increased excretion of dimethyl and diethyl metabolites of organophosphates was associated with increased reaction time and no other outcomes. CONCLUSION Prenatal pesticide exposure may cause lasting neurotoxic damage and add to the adverse effects of malnutrition in developing countries. The effects differ from those due to acute pesticide exposure.
