Influence of maternal stature, pregnancy age, and infant birth weight on growth during childhood in Yucatan, Mexico: A test of the intergenerational effects hypothesis,

AMERICAN JOURNAL OF HUMAN BIOLOGY, Issue 5 2009
Maria Inês Varela-Silva
In developing nations, obesity has increased dramatically in the last decade, but a high prevalence of stunting still coexists. The intergenerational influences hypothesis (IIH) is one explanation for this. We test the IIH regarding variation in maternal stature, mother's age at pregnancy, and infant birth weight in relation to risk for overweight and stunting in 206 Maya children (4,6 years old) from Mérida, Yucatan, Mexico. The Maya children are compared with growth references (Frisancho 2008: Anthropometric Standards: An Interactive Nutritional Reference of Body Size and Body Composition for Children and Adults. Ann Arbor, MI: The University of Michigan Press. 335 pp) for height, weight, and body mass index (BMI). Almost 70% of the mothers are shorter than 150 cm. Mothers' height and child's birth weight predict overweight. Children with a mother shorter than 150 cm are less than half as likely (OR = 0.44) to be overweight compared to children whose mothers are equal to or taller than 150 cm. Children with birth weights below 3,000 g are only a third as likely to be overweight (OR = 0.28) than their peers within the range of normal birth weight (3,000,3,500 g). Sex of the child, mother's height, and birth weight predict stunting. Girls are only 40% as likely as boys to be stunted. Children with a mother below 150 cm are 3.6 times more likely of being stunted. Children with birth weights below 3000 g are over 3 times more likely to be stunted relative to children with birth weights within the normal range. Mother's age at pregnancy is not a predictor of overweight or stunting. Our findings conform the IIH and with similar studies of populations undergoing nutritional/epidemiological transitions from traditional to globalized lifestyles. Am. J. Hum.

The comparison of health status and health services utilisation between Indigenous and non-Indigenous infants in Australia

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 1 2010
Lixin Ou
Abstract Objective: To examine the differences in health services utilisation and the associated risk factors between Indigenous and non-Indigenous infants at a national level in Australia. Methods: We analysed data from a national representative longitudinal study, the Longitudinal Study for Australian Children (LSAC) starting in 2004. We used survey logistic regression and survey multiple linear regression to examine the factors associated with health services utilisation. Results: Health status of Indigenous infants was poorer than that of non-Indigenous. In comparison to non-Indigenous infants, in the previous 12-month period, the Indigenous infants were significantly less likely to use the following health services: maternal and child health centre or help lines (OR=0.35, 95%CI: 0.24-0.49); maternal and child health nurse visits (OR=0.45, 95%CI: 0.32-0.63); general practitioners (GPs) (OR=0.45, 95%CI: 0.31-0.64); and paediatrician (OR=0.52, 95%CI: 0.35-0.77). In contrast, they were more likely to visit a hospital outpatient clinic (OR=1.82, 95%CI: 1.16-2.85). Mothers' age, education and marital status were associated with certain health services use. Financial status and residential location were the important predictors of the use of health services. Conclusion: The rates of health services utilisation by Indigenous infants were lower and were associated with mothers' characteristics and socio-economic status. Implications: The gaps in health services utilisation between Indigenous and non-Indigenous infant requires immediate policy initiatives. Further research is needed to explore the causal pathways between health status, health services utilisation and multiple risk factors at different levels. [source]

The Course and Quality of Intimate Relationships Among Psychologically Distressed Mothers

AMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 1 2010
Lauren M. Papp
The longitudinal course and quality of intimate relationships were tested in relation to maternal depressive symptoms in a sample of 1,275 families from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Assessments of mothers' intimate relationship status, intimate relationship quality, and depressive symptoms were obtained on 11 occasions from the birth of a child through age 15. Consistent with predictions, results from hierarchical linear models indicated that maternal depressive symptoms over time were associated with a lower probability of being married and lower levels of relationship quality. The strength of the association between relationship quality and depression was stronger than the linkage between relationship course and depression. Sociodemographic characteristics (e.g., mother age, child gender, ethnicity) were more predictive of trajectories of relationship course than relationship quality. Findings are discussed in terms of efforts to prevent and treat the longitudinal interplay between poor intimate relationship functioning and partners' psychopathology and its implications for the overall health and well-being of parents, couples, and children.

Complementary and alternative medicine use in families of children with cerebral palsy

DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 6 2003
Edward A Hurvitz MD
In order to assess patterns of usage of complementary and alternative medicine (CAM) in families of children with cerebral palsy (CP), 213 families with a child (0 to 18 years) with CP were recruited at the university medical center in Ann Arbor, MI, USA as part of a descriptive survey. Two hundred and thirty-five surveys were distributed. Mean age of the child was 8 years 6 months (SD 4y: 9mo) and 56% of the sample was male with 35% full-time independent ambulators, while the rest used an assistive device or a wheelchair. Fifty-four percent were in special education classrooms. Families were given a survey on functional status of the child with CP, CAM usage of the child and the parent, factors influencing the decision to use CAM, demographics, and clinical information. Of the families, 56%, used one or more CAM techniques. Massage therapy (25%) and aquatherapy (25%) were the most common. Children of families that used CAM were significantly younger (7y: 9mo, SD 4y: 7mo) than non-users (9y: 6mo, SD 4y: 6mo: t -test p < 0.01 two-tailed). Children with quadriplegic CP, with spasticity, and those who could not walk independently were more commonly exposed to CAM (Pearson's X2 [PX2] p=0.01 two-tailed; for mobility, odds ratio [OR] of 2.5 with regression). Mothers with a college degree had a greater tendency to use CAM for their child than those without (PX2p=0.01 two-tailed). Fathers of children who used CAM were older than fathers of those who did not (37y: 9mo versus 33y: 2mo, p=0.04 two-tailed). There was no significant difference between groups for mother's age, father's education, income, or for population of home town. Parents who used CAM for themselves were more likely to try CAM for their child (70% versus 47%, OR 2.1), and were much more likely to be pleased with the outcome (71% versus 42%, OR 3.5). Child's age (younger), lack of independent mobility, and parental use of CAM were the most significant predictive factors identified via logistic regression. [source]

Genetic and perinatal factors as risk for childhood type 1 diabetes

DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 6 2004
Karin Larsson
Abstract The mechanisms by which gestational infections, blood incompatibility, birth weight, mother's age and other prenatal or neonatal events increase the risk for type 1 diabetes are not understood. Studies so far have been retrospective, and there is a lack of population-based prospective studies. The possibility of identifying children at type 1 diabetes risk among first-degree relatives has resulted in prospective studies aimed at identifying postnatal events associated with the appearance of autoantibody markers for type 1 diabetes and a possible later onset of diabetes. However, the majority (85%) of new onset type 1 diabetes children do not have a first-degree relative with the disease. Population-based studies are therefore designed to prospectively analyse pregnant mothers and their offspring. One such study is DiPiS (Diabetes Prediction in Skåne), which is examining a total of about 10 000 pregnancies expected every year in the Skåne (Scania) region of Sweden that has 1.1 million inhabitants. Blood samples from all mothers in this region are obtained during pregnancy and at the time of delivery. Cord blood is analysed for HLA high-risk alleles and for autoantibodies against the 65 kD isoform of glutamic acid decarboxylase (GADA), the protein tyrosine phosphatase,related IA-2 antigen (IA-2A) and insulin (IAA) as a measure of prenatal autoimmune exposure. Identifying high-risk children by genetic, autoimmune and gestational risk factors followed by prospective analyses will make it possible to test the hypothesis that gestational events may trigger beta cell autoimmunity as a prerequisite for childhood type 1 diabetes.

Mothers reduce egg provisioning with age

ECOLOGY LETTERS, Issue 4 2003
David Giron
Abstract Precise and comprehensive data on resource allocation into individual eggs are rare and this empirical void in the literature of life history strategies contrasts with the large number of theoretical studies. We show a marked decrease in reproductive investment in eggs with mother's age for egg size, sugar, protein, lipid and energy contents of eggs for a parasitic wasp. Egg size is a good predictor of offspring fitness, measured as survival of starving neonate larvae, but does not reveal possible biochemical changes. Lipids stabilize quickly at a minimal threshold while proteins and sugars decrease smoothly down to about 30% of the amount invested in the first egg. Because proteins have the highest correlation with egg size, we predict that they should be better predictors of larval fitness than lipids and sugars. Assessing the adaptive value of the observed patterns will require a multidimensional approach to egg provisioning. [source]

The possible role of endocrine disrupting chemicals in the aetiology of cryptorchidism and hypospadias: a population-based case,control study in rural Sicily

INTERNATIONAL JOURNAL OF ANDROLOGY, Issue 1 2007
P. Carbone
Abstract This was an open case,control study of the possible association between parental occupational and domestic exposures to potential endocrine disrupting chemicals (EDC) assessed by questionnaire and cryptorchidism and hypospadias in their offspring in the agricultural area of Ragusa. Cases of infants born between 1998 and 2002 with either of these two malformations (n = 90), and controls (n = 203), were recruited through the paediatric services (for cases) and a random sample of healthy infants attending the same services born in the same period of time (for controls). Data on occupational and environmental exposures of parents prior to and during the index case (or control), were collected through interviews with both parents. Concerning occupational exposures, we did not find a statistically significant increase in risk among parents directly involved in agricultural work. We did find a non-statistically significant increase in risk for cryptorchidism in mothers employed in agriculture [adjusted odds ratios (OR) 2.97; 95% confidence interval (CI) 0.77,11.47] and with probable exposure to pesticides (adjusted OR 2.74; 95% CI 0.72,10.42). Fathers who had indirect contact with agricultural products (transport and retail) had an increased risk (not statistically significant) for cryptorchidism (adjusted OR 2.45; 95% CI 0.63,9.59) and hypospadias and cryptorchidism combined (adjusted OR 2.24; 95% CI 0.67,7.48). Increases in risk of the two malformations pooled were also observed in relation to the mother's age below 25 (adjusted OR 1.99; 95% CI 0.97,4.09), to the presence of genital disease of the father (adjusted OR 2.41; 95%C I0.94,6.17), and the mother (adjusted OR 3.47;95% CI1.34,8.99), to low birth weight of the infant (adjusted OR 4.49; 95% CI 1.23,16.31). Increased risk was also observed for mothers consuming alcohol during pregnancy (adjusted OR 3.09; 95% CI 0.98,9.66), and for couples who conceived while using condoms (adjusted OR 2.12; 95% CI 1.02,4.41). The study therefore provides only limited support to the hypothesis of a possible association between the risk of cryptorchidism and hypospadias and the occupational exposure to EDC and agricultural work.

Periodontal disease as a risk factor for adverse pregnancy outcomes: a prospective cohort study

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2008
Anna Agueda
Abstract Aim: The aim of this study was to determine the association between periodontitis and the incidence of preterm birth (PB), low birth weight (LBW) and preterm low birth weight (PLBW) Material and Methods: One thousand and ninty-six women were enrolled. Periodontal data, pregnancy outcome variables and information on other factors that may influence adverse pregnancy outcomes were collected. Data were analysed using a logistic regression model. Results: The incidence of PB and LBW was 6.6% and 6.0%, respectively. The incidence of PLBW was 3.3%. PB was related to mother's age, systemic diseases, onset of prenatal care, previous PBs, complications of pregnancy, type of delivery, the presence of untreated caries and the presence of periodontitis (odds ratio 1.77, 95% confidence interval: 1.08,2.88). LBW was related to mother's smoking habits, ethnicity, systemic diseases, previous LBW babies, complications of pregnancy and type of delivery. PLBW was related to mother's age, onset of prenatal care, systemic diseases, previous LBW babies, complications of pregnancy and type of delivery. Conclusions: The factors involved in many cases of adverse pregnancy outcomes have still not being identified, although systemic infections may play a role. This study found a modest association between periodontitis and PB. Further research is required to establish whether periodontitis is a risk factor for PB and/or LBW. [source]

Factors associated with resilience of school age children with cancer

JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 7-8 2010
Dong H Kim
Aim: To identify factors associated with resilience of school age children with cancer. Methods: The participants were 74 children, 10,15 years old who were diagnosed with cancer at least 6 months prior to data collection. The instruments used were; a self-reported questionnaire on resilience, Family Adaptability and Cohesion Evaluation Scale III, measurements of relationship with friends and teachers. Descriptive, Pearson correlation and multiple regression analyses were used to analyse the data. Results: The average score for resilience was 98.49 (range: 32,128). There was no statistically significant relationship with resilience for age, gender, religion, existence of siblings, mother's age, academic performance, duration of illness or type of cancer. In bivariate analysis, family adaptability and cohesion (r= 0.535, P < 0.001), relationship with friends (r= 0.520, P < 0.001) and teachers (r= 0.318, P < 0.01) were significantly related to resilience. However, the results of multiple regression analysis showed that only family function (,= 0.257, P < 0.05) and relationship with friends (,= 0.581, P < 0.01) were significantly associated with resilience. Conclusions: School age children with cancer who reported higher family function and positive relationships with friends showed higher resiliency than their counterparts. Thus, it is important to help the families of children with cancer to enhance family function and help children to adjust to school re-entry by maintaining ties with school friends and teachers during treatment. Development of counselling programmes for parents to promote family adaptation and cohesion and educational programmes for classmates and teachers are recommended. [source]

Effect of multiple birth on infant mortality in Bangladesh

JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 10 2006
Rathavuth Hong
Aim: Levels of infant and child mortality in many developing countries remain unacceptably high, and they are disproportionably higher among high-risk groups such as newborn and infant of multiple births, particularly in countries where advanced medical cares are available only at regional referral levels with limited access by the poor rural women and children. This study examined the relationship between high-risk infant of multiple birth and infant mortality in Bangladesh. Methods: The analysis uses information on 7001 childbirths in 5 years preceding the 2004 Bangladesh Demographic and Health Survey to examine the relationship between multiple birth and infant mortality using multivariate analysis, controlling for child's sex, birth order, prenatal care, delivery assistance; mother's age at child birth, nutritional status, education level; household living conditions and several other risk factors. Results: Results indicate that children born multiple birth were more than six-times as likely to die during infancy as those born singletons (hazard ratio = 6.51; 95% confidence interval: 4.10, 10.36). Controlling for all other risk factors does not change the strength and direction of the relationship (hazard ratio = 6.18; 95% confidence interval: 3.65, 10.46). Receiving prenatal care and access to safe drinking water are associated with lower risk. Conclusion: Multiple births are strongly negatively associated with infant survival in Bangladesh independent of other risk factors. This evidence suggests that improving maternal and child health at the community level, screening for high-risk pregnancies and making referral services for these conditions more accessible to the rural women and children will be key to improving child survival in Bangladesh.

Prospective community-based cluster census and case-control study of stillbirths and neonatal deaths in the West Bank and Gaza Strip

PAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 4 2008
Henry D. Kalter
Summary Obstetric complications and newborn illnesses amenable to basic medical interventions underlie most perinatal deaths. Yet, despite good access to maternal and newborn care in many transitional countries, perinatal mortality is often not monitored in these settings. The present study identified risk factors for perinatal death and the level and causes of stillbirths and neonatal deaths in the West Bank and Gaza Strip. Baseline and follow-up censuses with prospective monitoring of pregnant women and newborns from September 2001 to August 2002 were conducted in 83 randomly selected clusters of 300 households each. A total of 113 of 116 married women 15,49 years old with a stillbirth or neonatal death and 813 randomly selected women with a surviving neonate were interviewed, and obstetric and newborn care records of women with a stillbirth or neonatal death were abstracted. The perinatal and neonatal mortality rates, respectively, were 21.2 [95% confidence interval (CI) 16.5, 25.9] and 14.7 [95% CI 10.2, 19.2] per 1000 livebirths. The most common cause (27%) of 96 perinatal deaths was asphyxia alone (21) or with neonatal sepsis (5), while 18/49 (37%) early and 9/19 (47%) late neonatal deaths were from respiratory distress syndrome (12) or sepsis (9) alone or together (6). Constraint in care seeking, mainly by an Israeli checkpoint, occurred in 8% and 10%, respectively, of 112 pregnancies and labours and 31% of 16 neonates prior to perinatal or late neonatal death. Poor quality care for a complication associated with the death was identified among 40% and 20%, respectively, of 112 pregnancies and labour/deliveries and 43% of 68 neonates. (Correction added after online publication 5 June 2008: The denominators 112 pregnancies, labours, and labour/deliveries, and 16 and 68 neonates were included; and 9% of labours was corrected to 10%.) Risk factors for perinatal death as assessed by multivariable logistic regression included preterm delivery (odds ratio [OR] = 11.9, [95% CI 6.7, 21.2]), antepartum haemorrhage (OR = 5.6, [95% CI 1.5, 20.9]), any severe pregnancy complication (OR = 3.4, [95% CI 1.8, 6.6]), term delivery in a government hospital and having a labour and delivery complication (OR = 3.8, [95% CI 1.2, 12.0]), more than one delivery complication (OR = 4.4, [95% CI 1.8, 10.5]), mother's age >35 years (OR = 2.9, [95% CI 1.3, 6.8]) and primiparity in a full-term pregnancy (OR = 2.6, [1.1, 6.3]). Stillbirths are not officially reportable in the West Bank and Gaza Strip and this is the first time that perinatal mortality has been examined. Interventions to lower stillbirths and neonatal deaths should focus on improving the quality of medical care for important obstetric complications and newborn illnesses. Other transitional countries can draw lessons for their health care systems from these findings. [source]

Associations between dietary intake and breast milk dioxin levels in Tokyo, Japan

PEDIATRICS INTERNATIONAL, Issue 5 2005
Peng Guan
AbstractBackground:,The presence of dioxins in breast milk has gained much attention recently. However, in Japan the relationship between the consumption of different foods and the human breast milk dioxin concentrations is still unclear. Methods:,Breast milk was taken from 240 mothers residing in Tokyo, Japan to measure and analyze the concentrations of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and coplanar polychlorinated biphenyls contained in the fat. Individual milk samples were obtained from the mothers 30 days after delivery in 1999 and 2000. The data of the mothers' diets before pregnancy were collected by means of food frequency and amount estimation. Spearman correlation analysis and stepwise multiple linear regression were used to analyze the data. Results:,The concentrations of dioxins in breast milk were influenced mainly by the mother's age and history of breast-feeding. All the Spearman correlation coefficients were less than 0.20. Pork, roast ham, sausage, salt codfish and tempura had negative correlations with breast milk dioxins. Conclusions:,History of breast-feeding and the mother's age should be considered and emphasized in this kind of analysis. The cause effect relationship between dietary intake and breast milk dioxin levels were still uncertain. [source]

Mothers' awareness of their weight status and concern about their children being overweight: findings from first-time mothers in south-west Sydney

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 3 2010
Li Ming Wen
Abstract Objective: To assess mothers' awareness of their weight status and to investigate whether this awareness influences mothers' concerns about their child being overweight or obese. Design and setting: An analysis of cross-sectional baseline survey data from the Healthy Beginnings Trial conducted in south-west Sydney, NSW. Participants: A total of 667 first-time mothers at 24-36 weeks of pregnancy or within one month after giving birth, who participated in the Healthy Beginnings Trial. Results: Forty per cent of first-time mothers were overweight (24%) or obese (16%). Of these women 49% considered their weight acceptable and 21% had little or no concern about their child being overweight and obese. Concern about her child's weight was not dependent on the mother's age, marital status, education, employment, ethnicity or weight status. The only factor associated with concern about children being overweight was the mother's awareness of her own weight status. Mothers who were unaware of being overweight were twice as likely to be unconcerned about their children being overweight as those who were aware of their weight status (RR 1.98, 95% CI 1.19 to 3.29, p=0.009). Conclusions: There was a low level of awareness of mothers' own weight status, in particular among mothers who were young and less educated. This could lead to a lack of concern about their child being overweight. Implications: Early interventions to prevent childhood overweight and obesity need to improve mothers' awareness of their own weight status and appropriate concerns about children being overweight or obese.

Mortality throughout early childhood for Michigan children born with congenital anomalies, 1992-1998,

BIRTH DEFECTS RESEARCH, Issue 9 2003
Katherine H. Berger
BACKGROUND Congenital anomalies are a leading cause of infant deaths, accounting for almost a fifth of all infant deaths. Few studies have researched the survival experience of infants born with congenital anomalies past the infant stage. METHODS Using birth and death files routinely linked to the Michigan Birth Defects Registry, we identified all singleton infants during calendar years 1992 through 1998 with reportable congenital anomalies for our study. A comparative file of children born without congenital anomalies during the same time period was developed using linked birth and death files. The mortality data were assessed by age at death (through age six) and race to determine mortality rates, relative risks, hazard ratios, and survival trends. RESULTS Throughout early childhood, children born with congenital anomalies had a high risk of mortality compared with all other children. The overall 7-year hazard ratio comparing children with congenital anomalies with all other children was 7.2. Overall mortality rates for black children were significantly higher than white children through the age of seven, irrespective of whether they had congenital anomalies. Among children with congenital anomalies, this disparity disappeared after adjusting for birth weight, sex, mother's age, mother's education, and number of organ systems affected. CONCLUSIONS Compared with children without congenital anomalies, children born with congenital anomalies had a higher risk of mortality well beyond the infant period. Racial disparities in mortality rates among children with congenital anomalies were due to confounding factors. Birth Defects Research (Part A) 67656,661, 2003. © 2003 Wiley-Liss, Inc. [source]

Feeding practices of infants through the first year of life in Italy

ACTA PAEDIATRICA, Issue 4 2004
M Giovannini
Aim: To investigate infant feeding practices through the first year of life in Italy, and to identify factors associated with the duration of breastfeeding and early introduction of solid foods. Methods: Structured phone interviews on feeding practices were conducted with 2450 Italian-speaking mothers randomly selected among women who delivered a healthy-term singleton infant in November 1999 in Italy. Interviews were performed 30 d after delivery and when the infants were aged 3, 6, 9 and 12 mo. Type of breastfeeding was classified according to the WHO criteria. Results: Breastfeeding started in 91.1% of infants. At the age of 6 and 12mo, respectively, 46.8% and 11.8% of the infants was still breastfed, 68.4% and 27.7% received formula, and 18.3% and 65.2% were given cow's milk. Solids were introduced at the mean age of 4.3 mo (range 1.6,6.5 mo). Introduction of solids occurred before age 3 and 4 mo in 5.6% and 34.2% of infants, respectively. The first solids introduced were fruit (73.1%) and cereals (63.9%). The main factors (negatively) associated with the duration of breastfeeding were pacifier use (p > 0.0001), early introduction of formula (p > 0.0001), lower mother's age (p > 0.01) and early introduction of solids (p= 0.05). Factors (negatively) associated with the introduction of solids foods before the age of 3 mo were mother not having breastfed (p > 0.01), early introduction of formula (p > 0.01), lower infant bodyweight at the age of 1 mo (p= 0.05) and mother smoking (p= 0.05). Conclusion: The duration of breastfeeding in Italy is still inadequate, as well as compliance with international recommendations for timing of introduction of complementary foods. National guidelines, public messages and educational campaigns should be promoted in Italy. [source]

Maternal predictors of subcutaneous fat in the term newborn

ACTA PAEDIATRICA, Issue 3 2004
A-M Guihard-Costa
Aim: To determine the relative influences of some maternal factors on skinfold thickness. The effects of age, parity, height, body mass index (BMI) and pregnancy weight gain (PWG) of the mother on the subscapular skinfold thickness (SST) of the newborn were estimated, and compared with their effects on birthweight (BW), crown-heel length (CHL) and head circumference (HC). Methods: A sample of 13, 972 healthy, term singletons was selected at the Clamart Maternity Hospital (France). Stepwise regressions were used to determine the most predictive maternal factors for each parameter in the newborn. The respective effects of the mother's age and parity on each newborn dimension were tested by analysis of variance. Results: The SST is a singular parameter, influenced by the mother's BMI and PWG, but not by her height. In contrast, the main predictor of BW, CHL and HC is the height of the mother, and to a lesser extent her PWG and BMI. Parity and maternal age have a smaller effect, except on SST, and essentially between the first and second pregnancies. Conclusion: These results clearly separate SST from other newborn dimensions. The skinfold thickness depends only on the nutritional status of the mother, while other dimensions are markedly influenced by the genetic background. This study is the first to demonstrate the singularity of skinfold thickness in newborn infants as a marker of the mother's nutritional status. [source]
