Rudra CB, Williams MA, Schiff MA, Koenig JQ, Dills R, Yu J. A prospective study of maternal carboxyhaemoglobin and pre-eclampsia risk. Paediatric and Perinatal Epidemiology 2009. We aimed to measure the relationship between early-pregnancy maternal carboxyhaemoglobin and subsequent pre-eclampsia risk. A nested case[ndash]control analysis was conducted using data from a western Washington State cohort study (1996[ndash]2004). We measured maternal whole blood carboxyhaemoglobin in 128 women who developed pre-eclampsia and 419 normotensive controls (mean gestational age at blood draw, 14.8 weeks). After adjustment for confoun...

Survey of Neonates in Pomerania (SNiP): a population-based birth study – objectives, design and population coverageEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The objectives of SNiP are to establish (a) a population-based birth cohort providing detailed information about neonatal health, morbidity and mortality, (b) a biobank with newborn DNA and serum from cord blood, placenta tissue samples and DNA obtained from oral mucosal swabs of the mothers, (c) a prospective study design by re-examination of the SNiP population prior to attendance at primary school. From March 2003 until November 2008 all childbearing mothers in a well-defined region in North-Eastern Germany were asked to participate with their newborns. Detailed data on health status of the newborn, pregnancy, medical a...

Characteristics of prospectively measured vaginal bleeding among women trying to conceiveEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Previous research has described variability in menstrual cycle lengths within and across women, though less attention has focused on characterising patterns of bleeding. While clinical definitions for menstrual bleeding are often given in standard textbooks, the validity of conventional definitions has not been empirically evaluated in epidemiological studies. The definition of menstrual bleeding may affect the analysis of time to pregnancy and pregnancy dating that relies upon the last menstrual period. We used daily records of vaginal bleeding from a prospective cohort study that included 74 women trying to become pregna...

Lundberg F, Cnattingius S, D'Onofrio B, Altman D, Lambe M, Hultman C, Iliadou A. Maternal smoking during pregnancy and intellectual performance in young adult Swedish male offspring. Paediatric and Perinatal Epidemiology 2009. Smoking during pregnancy has been linked to an increased risk of several adverse birth outcomes. Associations with deficits in cognitive development have also been suggested. It is unclear whether these associations are due to genetic and/or environmental confounding. In a population-based Swedish cohort study on 205 777 singleton males born to Nordic mothers between 1983 and 1988, we examined the as...

Ullah A, Barman A, Haque J, Khanum M, Bari I. Birthweight and early neonatal health: Bangladesh perspective. Paediatric and Perinatal Epidemiology 2009. It has been suggested that a birthweight limit of 2.5 kg should not be regarded as valid for all populations as the cut-off point of low-weight births because of demographic, genetic and environmental differences. Countries often choose alternative cut-off values for low birthweight for clinical purposes. Bangladesh also needs to choose a convenient cut-off value for low birthweight.

We examined maternal OCP exposure in relation to asthma in the offspring (n = 6730) compared with offspring with no asthma (n = 6730) further stratifying by eczema, age group, treatment category and gender of the offspring. Maternal use of OCP was classified as: no OCP use in the 2 years prior to conception; past OCP use within 2 years but >6 months before conception; and recent OCP use within 6 months of conception. The adjusted odds ratio (OR) for asthma in the offspring was 1.16 [95% confidence interval 1.06, 1.27] among mothers who were recent users of the OCP when compared with mothers who had not used the OCP.

This study describes the timing of puberty in 8- to 13-year-old girls enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC) and identifies factors associated with earlier achievement of menarche. Women were enrolled during pregnancy and their offspring were followed prospectively. We analysed self-reported Tanner staging and menstrual status information collected annually from daughters up to age 13. We used survival models to estimate median age of attainment of stage >1 and stage >2 of breast and pubic hair development and of menarche.

In conclusion, 9[ndash]34% of pregnant women, depending on procedure, stated they would not participate in non-invasive research procedures such as medical record abstraction and infant examination, even with compensation. Resistance to these research procedures was especially noted among more highly educated women. Planning for the National Children's Study will have to address potential resistance to research among pregnant women. (Source: Paediatric and Perinatal Epidemiology)

Schisterman EF, Whitcomb BW, Mumford SL, Platt RW. Z-scores and the birthweight paradox. Paediatric and Perinatal Epidemiology 2009. Investigators have long puzzled over the observation that low-birthweight babies of smokers tend to fare better than low-birthweight babies of non-smokers. Similar observations have been made with regard to factors other than smoking status, including socio-economic status, race and parity. Use of standardised birthweights, or birthweight z-scores, has been proposed as an approach to resolve the crossing of the curves that is the hallmark of the so-called birthweight paradox.

McKinney CM, Cunningham ML, Holt VL, Leroux B, Starr JR. A case[ndash]control study of infant, maternal and perinatal characteristics associated with deformational plagiocephaly. Paediatric and Perinatal Epidemiology 2009. Deformational plagiocephaly, an abnormal asymmetric flattening of infants' heads, is diagnosed in approximately 10% of infants. The prevalence of plagiocephaly has increased dramatically since 1992 when it was first recommended that infants be placed to sleep in a non-prone position to reduce the risk of sudden infant death syndrome. The authors conducted a case[ndash]control study to evaluate associatio...

Prevalence and risk factors for anaemia in pregnant women: a population-based prospective cohort study in ChinaEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study was designed to explore the epidemiology and risk factors of anaemia during pregnancy. A prospective cohort study was conducted, using data from a population-based pregnancy-monitoring system in 13 counties in East China (1993[ndash]96). Women who delivered singleton infants at 20[ndash]44 weeks with at least one haemoglobin assessment during pregnancy were included (n = 164 667). The prevalence of anaemia (haemoglobin < 10 g/dL) during pregnancy as well as in each trimester was estimated. Multivariable log-binomial regression models were used to evaluate risk factors. The overall prevalence of anaemia in pregna...

Maternal obesity in pregnancy and respiratory health in early childhoodEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We examined the relationship between a high maternal body mass index (BMI) in pregnancy and lower respiratory tract infections and wheeze up to 18 months of age in the Norwegian Mother and Child Study (MoBa), a population-based cohort study that includes 100 000 pregnant women, conducted at the Norwegian Institute of Public Health. We analysed data from the first 33 192 children, born between 1999 and 2005. In unadjusted analyses maternal obesity in pregnancy was related to both respiratory infections and wheeze in the children. In multivariable analyses, only an effect on wheeze remained. The risk of wheeze increased line...

Guerrero-Romero F, Violante R, Rodríguez-Morán M. Distribution of fasting plasma glucose and prevalence of impaired fasting glucose, impaired glucose tolerance, and type 2 diabetes in the Mexican paediatric population. Paediatric and Perinatal Epidemiology 2009. Published data on the distribution of fasting plasma glucose (FPG) in children are scarce. We therefore set out to examine the distribution of FPG and determine the prevalence of impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and type 2 diabetes (T2-DM) in Mexican children aged 6[ndash]18 years in a community-based cross-sectional study. A total...

Do women change their health behaviours in pregnancy? Findings from the Southampton Women's SurveyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The objective of the analyses presented here is to describe the degree to which women comply with diet and life style recommendations before and during pregnancy, and changes between these time points. The analyses are based on 1490 women who delivered between 1998 and 2003 and who provided information before pregnancy and at 11 and 34 weeks' gestation. At each time point a trained research nurse ascertained smoking status and assessed food and drink consumption using a food frequency questionnaire. We derived the proportions of women who complied with recommendations not to smoke, to eat five portions of fruit and vegetab...

Paediatric and Perinatal Epidemiology 2009. Although low socio-economic status has consistently been associated with lower birthweight, little is known about the factors whereby socio-economic disadvantage influences birthweight. We therefore examined explanatory mechanisms that may underlie the association between the educational level of pregnant women, as an indicator of socio-economic status, and birthweight. The study was embedde...

Thompson ML, Williams MA, Miller RS. Modelling the association of blood pressure during pregnancy with gestational age and body mass index. Paediatric and Perinatal Epidemiology 2009. Improved understanding of the determinants of blood pressure (BP) changes during pregnancy is essential for decreasing the morbidity and mortality borne by women and their families worldwide. While most epidemiological studies consider associations based on categorical risk factor classifications, using measurements on a continuous scale has been advocated as a means of gaining richer insights into biological processes. We modelled the relati...

Gender-specific selection in utero among contemporary human birth cohortsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Catalano R, Ahern J, Bruckner T, Anderson E, Saxton K. Gender-specific selection in utero among contemporary human birth cohorts. Paediatric and Perinatal Epidemiology 2009. Much literature argues that natural selection has conserved mechanisms by which stressed females cull frail males in utero. This argument implies that males from low sex ratio birth cohorts should, on average, live longer than those from high sex ratio cohorts. Research reports such associations but these tests use completed lifespan as the outcome and, therefore, must end with cohorts born in 1913 because too many males survive from more contemporary ...
