The safety of home births has been widely debated. Observational studies examining maternal and neonatal outcomes of home births have become more frequent, and the quality of these studies has improved. The aim of the present study was to describe neonatal outcomes of home births compared with hospital births and to discuss which data are needed to evaluate the safety of home births. This was a register-based cohort study. Data on all births in Denmark (2003-2013) were collected from the Danish Medical Birth Registry (DMBR). The cohort included healthy women with uncomplicated pregnancies and no medical interventions during delivery. A total of 6,395 home births and 266,604 hospital births were eligible for analysis. Comparative analyses were performed separately in nulliparous and multiparous women. The outcome measures were neonatal mortality and morbidity. Frequencies of admission to a neonatal intensive care unit and treatment with continuous positive airway pressure were significantly lower in infants born at home than in infants born at a hospital. A slightly, but significantly increased rate of early neonatal death was found among infants delivered by nulliparous at home. This study indicates that home births in Denmark are characterized by a high level of safety owing to low rates of perinatal mortality and morbidity. Missing registration on intrapartum transfers and planned versus unplanned home births in the DMBR are, however, major limitations to the validity and utility of the reported results. Registration of these items of information is necessary to make reasonable assessments of home births in the future. none. not relevant. Articles published in the DMJ are “open access”.

Objectives To quality assure a Trusted Third Party linked data set to prepare it for analysis. Setting Birth registration and notification records from the Office for National Statistics for all births in England 2005–2014 linked to Maternity Hospital Episode Statistics (HES) delivery records by NHS Digital using mothers’ identifiers. Participants All 6 676 912 births that occurred in England from 1 January 2005 to 31 December 2014. Primary and secondary outcome measures Every link between a registered birth and an HES delivery record for the study period was categorised as either the same baby or a different baby to the same mother, or as a wrong link, by comparing common baby data items and valid values in key fields with stepwise deterministic rules. Rates of preserved and discarded links were calculated and which features were more common in each group were assessed. Results Ninety-eight per cent of births originally linked to HES were left with one preserved link. The majority of discarded links were due to duplicate HES delivery records. Of the 4854 discarded links categorised as wrong links, clerical checks found 85% were false-positives links, 13% were quality assurance false negatives and 2% were undeterminable. Births linked using a less reliable stage of the linkage algorithm, births at home and in the London region, and with birth weight or gestational age values missing in HES were more likely to have all links discarded. Conclusions Linkage error, data quality issues, and false negatives in the quality assurance procedure were uncovered. The procedure could be improved by allowing for transposition in date fields, and more discrimination between missing and differing values. The availability of identifiers in the datasets supported clerical checking. Other research using Trusted Third Party linkage should not assume the linked dataset is error-free or optimised for their analysis, and allow sufficient resources for this. PMID:29500200

We evaluated the birth outcomes of planned home births. We conducted a retrospective cohort study using Missouri vital records from 1989 to 2005 to compare the risk of newborn seizure and intrapartum fetal death in planned home births attended by physicians/certified nurse midwives (CNMs) or non-CNMs with hospitals/birthing center births. The study sample included singleton pregnancies between 36 and 44 weeks of gestation without major congenital anomalies or breech presentation ( N = 859,873). The adjusted odds ratio (aOR) of newborn seizures in planned home births attended by non-CNMs was 5.11 (95% confidence interval [CI]: 2.52, 10.37) compared with deliveries by physicians/CNMs in hospitals/birthing centers. For intrapartum fetal death, aORs were 11.24 (95% CI: 1.43, 88.29), and 20.33 (95% CI: 4.98, 83.07) in planned home births attended by non-CNMs and by physicians/CNMs, respectively, compared with births in hospitals/birthing centers. Planned home births are associated with increased likelihood of adverse birth outcomes. © Thieme Medical Publishers.

Full Text Available Background: Expectant parents of very preterm infants, physicians and policy makers require estimates for chances of survival and survival without morbidity. Such estimates should derive from a large, reliable and contemporary data base of easily available items known at birth.Objective: To determine short-term outcome and risk factors in very low birth weight preterm infants based on administrative dataMethods: Anonymized routine data sets transmitted from hospital administrations to statutory health insurance companies were used to assess survival and survival free of major morbidities in a large cohort of preterm infants in Germany.Results: After exclusion of infants with lethal malformations, there were 13,147 infants with a birth weight below 1,500 g admitted to neonatal care 2008-2012, of whom 1,432 infants (10.9% died within 180 d. Estimated 180 d survival probabilities were 0.632 [95% confidence interval 0.583-0.677] for infants with 250-499 g birth weight, 0.817 [0.799-0.834] for 500-749 g, 0.931 [0.920-0.940] for 750-999 g, 0.973 [0.967-0.979] for 1,000-1,249 g and 0.985 [0.981-0.988] for 1,250-1,499 g. Estimated probabilities for survival without major morbidity (surgically treated intraventricular hemorrhage, necrotizing enterocolitis, intestinal perforation, or retinopathy were 0.433 [0.384-0.481] (250-499 g, 0.622 [0.600-0.643] (500-749 g, 0.836 [0.821-0.849] (750-999 g, 0.938 [0.928-0.946] (1,000-1,249 g, and 0.969 [0.964-0.974] (1,250-1,499 g, respectively. Prediction of survival and survival without major morbidities was moderately improved by adding sex, small-for-gestational-age, and severe or moderate congenital malformation, increasing ROC areas under the curve from 0.839 [0.827-0.850] to 0.862 [0.852-0.874] (survival and from 0.827 [0.822-0.842] to 0.852 [0.846-0.863] (survival without major morbidities, respectively.

Peranakan Ongole (PO) is a major Indonesian Bos indicus breed that derives from animals imported from India in the late 19(th) century. Early imports were followed by hybridization with the Bos javanicus subspecies of cattle. Here, we used genomic data to partition the ancestry components of PO cattle and map loci implicated in birth weight. We found that B. javanicus contributes about 6-7% to the average breed composition of PO cattle. Only two nearly fixed B. javanicus haplotypes were identified, suggesting that most of the B. javanicus variants are segregating under drift or by the action of balancing selection. The zebu component of the PO genome was estimated to derive from at least two distinct ancestral pools. Additionally, well-known loci underlying body size in other beef cattle breeds, such as the PLAG1 region on chromosome 14, were found to also affect birth weight in PO cattle. This study is the first attempt to characterize PO at the genome level, and contributes evidence of successful, stabilized B. indicus x B. javanicus hybridization. Additionally, previously described loci implicated in body size in worldwide beef cattle breeds also affect birth weight in PO cattle.

Objective: To identify factors affecting birth weight and pre-term birth, and to find associations with electromagnetic devices such as television, computer and mobile phones. Methods: The study was conducted in Turkey at Gazintep University, Faculty of Medicine Outpatient Clinic at the Paediatric Ward. It comprised 500 patients who presented at the clinic from May to December 2009. All participants were administered a questionnaire regarding their pregnancy history. SPSS 13 was used for statistical analysis. Results: In the study, 90 (19%) patients had pre-term birth , and 64 (12.9%) had low birth weight rate Birth weight was positively correlated with maternal age and baseline maternal weight (r= 0.115, p= 0.010; r= 0.168, p=0.000, respectively). Pre-term birth and birth weight less than 2500g were more common in mothers with a history of disease during pregnancy (p=0.046 and p=0.008, respectively). The habit of watching television and using mobile phones and computer by mothers did not demonstrate any relationship with birth weight. Mothers who used mobile phones or computers during pregnancy had more deliveries before 37 weeks (p=0.018, p=0.034; respectively). Similarly, pregnancy duration was shorter in mothers who used either mobile phone or computers during pregnancy (p=0.005, p=0.048, respectively). Conclusion: Mobile phones and computers may have an effect on pre-term birth. (author)

Maternal residential proximity to roads has been associated with adverse pregnancy outcomes. However, there is no study investigating mediators or buffering effects of road-adjacent trees on this association. We investigated the association between mothers' residential proximity to major roads and term low birth weight (LBW), while exploring possible mediating roles of air pollution (PM(2.5), PM(2.5-10), PM(10), PM(2.5) absorbance, nitrogen dioxide, and nitrogen oxides), heat, and noise and buffering effect of road-adjacent trees on this association. This cohort study was based on 6438 singleton term births in Barcelona, Spain (2001-2005). Road proximity was measured as both continuous distance to and living within 200 m from a major road. We assessed individual exposures to air pollution, noise, and heat using, respectively, temporally adjusted land-use regression models, annual averages of 24-hour noise levels across 50 m and 250 m, and average of satellite-derived land-surface temperature in a 50-m buffer around each residential address. We used vegetation continuous fields to abstract tree coverage in a 200-m buffer around major roads. Living within 200 m of major roads was associated with a 46% increase in term LBW risk; an interquartile range increase in heat exposure with an 18% increase; and third-trimester exposure to PM(2.5), PM(2.5-10), and PM10 with 24%, 25%, and 26% increases, respectively. Air pollution and heat exposures together explained about one-third of the association between residential proximity to major roads and term LBW. Our observations on the buffering of this association by road-adjacent trees were not consistent between our 2 measures of proximity to major roads. An increased risk of term LBW associated with proximity to major roads was partly mediated by air pollution and heat exposures.

Home births are common in resource poor countries and postnatal practices vary from one community to the other. To determine the proportion of home births, reasons for home delivery, and evaluate postnatal practices in Madagali, north-eastern Nigeria. This was a cross-sectional descriptive study of 400 women of reproductive age, who had put to birth in the past 1 year. The study was carried out over a period of 8 weeks from April to June 2010. The multistage method of sampling was used to select respondents. In the first stage, four of the five health districts were chosen randomly, namely, Gulak, Madagali, Sukur, and Duhu. The questionnaires were evenly distributed among the four health districts. In the second stage, from each district, two villages were chosen by simple random sample. In the third stage, two wards were selected in each village by simple random sampling. Of the 400 respondents interviewed, 289 (72.2%) were aged between 20 and 39 years, and most, 374 (93.5%) were married. Only 14 (3.5%) had tertiary education. Most respondents, 224 (56.0%) were farmers and grandmultiparae, 187 (46.7%). A total of 196 (49.0%) women delivered at home, whereas 204 (51.0%) delivered at the hospital. Of the 196 respondents who delivered at home, the bedroom 142 (72.4%), was the preferred place of birth. The most common reason for home birth was short duration of labor in 71 (36.3%) cases. Delivery was conducted by untrained persons in 50, (25.4%), whereas 99 (50.8%) and 31 (15.5%) deliveries were supervised by Traditional Birth Attendants (TBAs) and Midwives/Nurses, respectively. Postpartum, the majority, 235 (58.7%) respondents used sanitary pads to stanch lochia, whereas 140 (35%) used rags. A significant number of births take place in the home and supervised by unskilled persons. Against the backdrop of poor education and low socio-economic status of respondents, perineal hygiene can be adjudged satisfactory. There is the need to increase on the number of hospital

Birth order and risk taking in athletics: a meta-analysis and study of major league baseball.

According to expectations derived from evolutionary theory, younger siblings are more likely than older siblings to participate in high-risk activities. The authors test this hypothesis by conducting a meta-analysis of 24 previous studies involving birth order and participation in dangerous sports. The odds of laterborns engaging in such activities were 1.48 times greater than for firstborns (N = 8,340). The authors also analyze performance data on 700 brothers who played major league baseball. Consistent with their greater expected propensity for risk taking, younger brothers were 10.6 times more likely to attempt the high-risk activity of base stealing and 3.2 times more likely to steal bases successfully (odds ratios). In addition, younger brothers were significantly superior to older brothers in overall batting success, including two measures associated with risk taking. As expected, significant heterogeneity among various performance measures for major league baseball players indicated that older and younger brothers excelled in different aspects of the game.

Weerasinghe, D P; Parr, N J; Yusuf, F

2009-05-01

This study used life table methods to evaluate the potential effects of reduction in major disease mortality on life expectancy in New South Wales (NSW), and the differences in cause-specific mortality between country of birth groups. The total and partial elimination of major causes of death were examined to identify the high-risk groups for community-level health planning. Life tables were used to combine the mortality rates of the NSW population at different ages into a single statistical model. Using abridged, multiple decrement and cause-elimination life tables with the mortality data for NSW in 2000-2002, broader disease groups were examined. Multiple decrement tables were generated by country of birth. The effect of the partial elimination of ischaemic heart disease (IHD) was also studied. This study found that Pacific-born men and women who reach their 30th birthday and eventually die from IHD are expected to live, on average, 10.8 and 5.8 years less, respectively, than average men and women in NSW. If IHD is eliminated as a cause of death, 7.5 years for males and 6.7 years for females would be added to life expectancy at birth. Life expectancy at birth is likely to be further increased by reducing deaths caused by diseases of the cardiovascular system, particularly among people aged over 65 years, by reducing malignant neoplasm deaths among those aged below 65 years, and by reducing deaths due to accidents, injury and poisoning, mainly among men aged 15-29 years. Further gains in life expectancy could be achieved with community-level educational programmes on lifestyle management and disease prevention.

midwifery homes (similar to birth centres) are rich in midwifery wisdom and skills that differ from those in hospital obstetrical departments, and a certain percentage of pregnant women prefer birth in these settings. This study aimed to understand the organisation of the perinatal environment considered important by independent midwives in non-hospital settings and to clarify the processes involved. semi-structured qualitative interview study and constant comparative analysis. 14 independent midwives assisting at births in midwifery homes in Japan, and six independent midwives assisting at home births. Osaka, Kyoto, Nara, and Shiga, Japan. midwives assisting at non-hospital births organised the birth environment based on the following four categories: 'an environment where the mother and family are autonomous'; 'a physical environment that facilitates birth'; 'an environment that facilitates the movement of the mother for birth'; and 'scrupulous safety preparation'. These, along with their sub-categories, are presented in this paper. independent midwives considered it important to create a candid relationship between the midwife and the woman/family from the period of pregnancy to facilitate birth in which the woman and her family were autonomous. They also organised a distinctive environment for non-hospital birth, with preparations to guarantee safety. Experiential knowledge and skills played a major part in creating an environment to facilitate birth, and the effectiveness of this needs to be investigated objectively in future research.

The Effect of Activity Restriction on Infant's Birth Weight and Gestational Age at Birth: PRAMS Data Analysis.

Science.gov (United States)

Omar, Abeer

2018-01-01

Activity restriction is extensively prescribed for pregnant women with major comorbidities despite the lack of evidence to support its effectiveness in preventing preterm birth or low birth weight. To determine the moderation effect of home activity restriction for more than a week on infant's birth weight and gestational age at birth for high-risk women with obstetrical and medical comorbidities. A secondary analysis of 2004-2008 New York Pregnancy Risk Assessment Monitoring System was conducted with 1426 high-risk women. High-risk group included 41% of women treated with activity restriction and 59% of those not treated with activity restriction. Women with preterm premature rupture of membrane (PPROM) who were treated with activity restriction had a lower infant birth weight ( b = -202.85, p = ≤.001) and gestational age at birth ( b = -.91, p = ≤.001) than those without activity restriction. However, women with preterm labor and hypertensive disorders of pregnancy who were not treated with activity restriction had lower infant gestational age at birth ( b = -96, p = ≤.01) and ( b = -92, p = ≤.001), respectively, compared to those who were treated with activity restriction. Findings suggest a contrary effect of activity restriction on infants born to women with PPROM, which is a major reason for prescribing activity restriction. The current study results may trigger the need to conduct randomized control trials to determine the effect of severity of activity restriction on maternal and infant outcomes.

We explore to what extent stars within Galactic disk open clusters resemble each other in the high-dimensional space of their photospheric element abundances and contrast this with pairs of field stars. Our analysis is based on abundances for 20 elements, homogeneously derived from APOGEE spectra (with carefully quantified uncertainties of typically 0.03 dex). We consider 90 red giant stars in seven open clusters and find that most stars within a cluster have abundances in most elements that are indistinguishable (in a {χ }2-sense) from those of the other members, as expected for stellar birth siblings. An analogous analysis among pairs of > 1000 field stars shows that highly significant abundance differences in the 20 dimensional space can be established for the vast majority of these pairs, and that the APOGEE-based abundance measurements have high discriminating power. However, pairs of field stars whose abundances are indistinguishable even at 0.03 dex precision exist: ∼0.3% of all field star pairs and ∼1.0% of field star pairs at the same (solar) metallicity [Fe/H] = 0 ± 0.02. Most of these pairs are presumably not birth siblings from the same cluster, but rather doppelgängers. Our analysis implies that “chemical tagging” in the strict sense, identifying birth siblings for typical disk stars through their abundance similarity alone, will not work with such data. However, our approach shows that abundances have extremely valuable information for probabilistic chemo-orbital modeling, and combined with velocities, we have identified new cluster members from the field.

CHANGES IN SEX RATIO AT BIRTH IN CHINA: A DECOMPOSITION BY BIRTH ORDER.

2017-11-01

The long-term high sex ratio at birth (SRB) is a serious issue in China. In this study, changes in SRB were decomposed into variations in SRB by birth order and compositional changes in female births by birth order. With SRB data from China's surveys and censuses, and SRB data from South Korea's vital registration and censuses from 1980-2015, the trend and decomposition results in SRB were compared between China and South Korea, and the decomposition results for urban and rural SRBs, and for provinces, are presented. In both China and South Korea the rise in the SRB was driven by a rise in the SRB at all birth orders, which was only partly counteracted by the change in the distribution of births by order. The overall rise in the SRB ended when there was a decline in the SRB at second birth or above in South Korea. In China the total effect of variations in SRB of all birth orders increased more for the rural population than for the urban population before 2000, resulting in a higher total SRB for rural than urban population. After 2000, the total effect of variations in SRB of all birth orders lowered the total SRB for the rural population, whereas the effect of compositional change increased the total SRB, leading to a very slight rise in the total SRB for the rural population. At the province level, there was no spatial autocorrelation for the changes in total SRB by province, the total effect of variations in SRB of all birth orders or the effect of compositional change. The effect of variations in SRB by birth order accounted for the majority of changes in total SRB in most provinces.

The novice birthing: theorising first-time mothers' experiences of birth at home and in hospital in Australia.

to explore first-time mothers' experiences of birth at home and in hospital in Australia. a grounded theory methodology was used. Data were generated from in-depth interviews with women in their own homes. Sydney, Australia. 19 women were interviewed. Seven women who gave in a public hospital and seven women who gave birth for the first time at home were interviewed and their experiences were contrasted with two mothers who gave birth for the first time in a birth centre, one mother who gave birth for the first time in a private hospital and two women who had given birth more than once. three categories emerged from the analysis: preparing for birth, the novice birthing and processing the birth. These women shared a common core experience of seeing that they gave birth as 'novices'. The basic social process running through their experience of birth, regardless of birth setting, was that, as novices, they were all 'reacting to the unknown'. The mediating factors that influenced the birth experiences of these first-time mothers were preparation, choice and control, information and communication, and support. The quality of midwifery care both facilitated and hindered these needs, contributing to the women's perceptions of being 'honoured'. The women who gave birth at home seemed to have more positive birth experiences. identifying the novice status of first-time mothers and understanding the way in which they experience birth better explains previous research that reports unrealistic expectations and fear that may be associated with first-time birthing. It demonstrates how midwives can contribute to positive birth experiences by being aware that first-time mothers, irrespective of birth setting, are essentially reacting to the unknown as they negotiate the experience of birth.

Full Text Available Background: Low birth weight remains a major reason behind childhood malnutrition. The NFHS findings show no dent in this problem. Objective: This study was undertaken to explore change in birth weights in a period from 1989 to 2007 and any associations thereof. Materials and Methods: All birth records of a private rural hospital spanning two decades (1989-2007 were analyzed for birth weight, age of mother, gender, birth order of the baby, proportion of pre-term babies and low birth weight babies. Results: No change was observed in the average birth weights (average 2.71 kg over the period. Although the birth weight shows some expected variance with the age of mother, it was found to have no relation with the baby′s birth order and gender. The low birth weight proportion is about 24% and shows little difference before and after the series midpoint of year 1998. Conclusion: The birth weights have hardly changed in this population in the two decades.

Objective. To establish the percentile charts of birth weights for gestational age and sex within the Cameroonian population. Methods. A review of medical records of infants born between January 2007 and December 2011 at the maternities of two hospitals in Cameroon, Central Africa. Multiple pregnancies, births of HIV infected women, stillbirths, and births with major fetal malformations were excluded. The smooth curves of birth weight for gestational age and sex were created using the Gamlss package under R.3.0.1 software. Results. The birth weights of 12837 live birth singleton infants born to HIV negative women between 28 and 42 weeks of gestation were analyzed to construct the birth weight curves for gestational age and sex. The smoothed percentile curves of birth weights for gestational age and sex of Cameroonian infants have demonstrated an increasing slope until 40 weeks and then a plateau. There was a varied difference of distribution in birth weights for gestational age between Cameroonian, Botswanan, American, and French infants. Conclusion. We established the reference curves of birth weights for gestational age and sex for Cameroonians. The difference in birth weight curves noted between Cameroonian, Botswanan, American, and French infants suggests the importance of establishing the regional birth weight norms.

Midwife-attended births in the United States, 1990-2012: results from revised birth certificate data.

Declercq, Eugene

2015-01-01

Data on attendance at birth by midwives in the United States have been available on the national level since 1989, allowing for the documentation of long-term trends. New items on payer source and prepregnancy body mass index (BMI) from a 2003 revision of the birth certificate provide an opportunity to examine additional aspects of US midwifery practice. The data in this report are based on records on birth attendant gathered as part of the US National Standard Certificate of Live Birth from a public use Web site, Vital Stats (http://www.cdc.gov/nchs/VitalStats.htm), which allows users to create and download specialized tables. Analysis of new items on prepregnancy BMI and birth payer source are limited to the 38 states (86% of US births) that adopted the revised birth certificate by 2012. Between 1989 and 2012, the proportion of all births attended by certified nurse-midwives (CNMs) increased from 3.3% to 7.9%. The proportion of vaginal births attended by CNMs reached an all-time high of 11.9%. Births attended by "other midwives" (typically certified professional midwives) rose to a peak of 28,343, or 0.7% of all US births. The distribution of payer source for CNM-attended births (44% Medicaid; 44% private insurance; 6% self-pay) is very similar to the national distribution, whereas the majority (53%) of births attended by other midwives are self-pay. Women whose births are attended by other midwives are less likely (13%) to have a prepregnancy BMI in the obese range than women attended by CNMs (19%) or overall (24%). The total number of births attended by CNMs and other midwives has remained steady or grown at a time when total US births have declined, resulting in the largest proportions of midwife-attended births in the quarter century that such data have been collected. © 2015 by the American College of Nurse-Midwives.

Labor market segmentation and relative black/white teenage birth rates.

Science.gov (United States)

Mccrate, E

1990-01-01

"Teenage mothers typically have lower educational attainment than other women. Most observers have argued that this is a major reason for their greater risk of poverty. This article takes the opposite view: that circumstances associated with poverty contribute to a greater likelihood of teenage childbearing. In particular, poor educational quality and the chances of secondary sector employment are more common for black women, regardless of their age at first birth. Hence the payoffs to education may be quite low for these women, which may be the reason for early motherhood. This argument is presented in terms of segmented labor market theory. Data to support it is presented from the [U.S.] National Longitudinal Survey of Youth. Other common explanations of teenage motherhood are critiqued." excerpt

Inequality in access to health care in Cambodia: socioeconomically disadvantaged women giving birth at home assisted by unskilled birth attendants.

Cambodia faces major challenges in its effort to provide access to health care for all. Although there is a sharp improvement in health and health care in Cambodia, 6 in 10 women still deliver at home assisted by unskilled birth attendants. This practice is associated with higher maternal and infant deaths. This article analyzes the 2005 Cambodia Demographic and Health Survey data to examine the relationship between socioeconomic inequality and deliveries at home assisted by unskilled birth attendants. It is evident that babies in poorer households are significantly more likely to be delivered at home by an unskilled birth attendant than those in wealthier households. Moreover, delivery at home by an unskilled attendant is associated with mothers who have no education, live in a rural residence, and are farmers, and with higher birth order children. Results from this analysis demonstrate that socioeconomic inequality is still a major factor contributing to ill health in Cambodia. © 2011 APJPH.

During the last decade, a rapid increase of birth locations for low-risk births, other than conventional obstetric units, has been seen in the Netherlands. Internationally some of such locations are called birth centres. The varying international definitions for birth centres are not directly applicable for use within the Dutch obstetric system. A standard definition for a birth centre in the Netherlands is lacking. This study aimed to develop a definition of birth centres for use in the Netherlands, to identify these centres and to describe their characteristics. International definitions of birth centres were analysed to find common descriptions. In July 2013 the Dutch Birth Centre Questionnaire was sent to 46 selected Dutch birth locations that might qualify as birth centre. Questions included: location, reason for establishment, women served, philosophies, facilities that support physiological birth, hotel-facilities, management, environment and transfer procedures in case of referral. Birth centres were visited to confirm the findings from the Dutch Birth Centre Questionnaire and to measure distance and time in case of referral to obstetric care. From all 46 birth locations the questionnaires were received. Based on this information a Dutch definition of a birth centre was constructed. This definition reads: "Birth centres are midwifery-managed locations that offer care to low risk women during labour and birth. They have a homelike environment and provide facilities to support physiological birth. Community midwives take primary professional responsibility for care. In case of referral the obstetric caregiver takes over the professional responsibility of care." Of the 46 selected birth locations 23 fulfilled this definition. Three types of birth centres were distinguished based on their location in relation to the nearest obstetric unit: freestanding (n = 3), alongside (n = 14) and on-site (n = 6). Transfer in case of referral was necessary for all

Progesterone for preterm birth prevention

Full Text Available Background: Progesterone is important in maintaining pregnancy. Progesterone supplementation may reduce risk of preterm birth in certain populations of pregnant women. The objective of this review was to develop evidence-based clinical recommendation for progesterone treatment in the prevention of preterm birth.Methods: A search in the Medline database was performed using keywords: progesterone, pregnancy, preterm birth, preterm labour, preterm delivery, randomized trial, and randomized controlled trial. We only included studies of vaginal progesterone treatments for the prevention of preterm birth and excluded studies on 17-α-hydroksiprogesterone caproate.Results: We report findings from twelve randomized trials conducted since 2003. These trials differ regarding inclusion criteria, progesterone dose, vehicle used, and duration of treatment. Inclusion criteria were: short uterine cervix (two trials, history of previous preterm birth (two trials, signs and symptoms of preterm labour (three trials, twin pregnancies (three trials, and multiple risk factors (among these history of previous preterm birth was the most common (two trials. Six of these twelve trials showed a significant reduction in preterm birth in the progesterone groups.Conclusions: Based on current evidence we recommend treatment with 200 mg of micronized progesterone daily, administered vaginally, in pregnant women found to have a short cervix (≤ 25 mm at 19-24 weeks. The treatment should be continued until 37 weeks.

Abu-Saad, Kathleen; Fraser, Drora

2010-01-01

In this review, the authors summarize current knowledge on maternal nutritional requirements during pregnancy, with a focus on the nutrients that have been most commonly investigated in association with birth outcomes. Data sourcing and extraction included searches of the primary resources establishing maternal nutrient requirements during pregnancy (e.g., Dietary Reference Intakes), and searches of Medline for "maternal nutrition"/[specific nutrient of interest] and "birth/pregnancy outcomes," focusing mainly on the less extensively reviewed evidence from observational studies of maternal dietary intake and birth outcomes. The authors used a conceptual framework which took both primary and secondary factors (e.g., baseline maternal nutritional status, socioeconomic status of the study populations, timing and methods of assessing maternal nutritional variables) into account when interpreting study findings. The authors conclude that maternal nutrition is a modifiable risk factor of public health importance that can be integrated into efforts to prevent adverse birth outcomes, particularly among economically developing/low-income populations.

Prevention of preterm birth.

LENUS (Irish Health Repository)

Flood, Karen

2012-02-01

Preterm birth (delivery before 37 completed weeks of gestation) is common and rates are increasing. In the past, medical efforts focused on ameliorating the consequences of prematurity rather than preventing its occurrence. This approach resulted in improved neonatal outcomes, but it remains costly in terms of both the suffering of infants and their families and the economic burden on society. Increased understanding of the pathophysiology of preterm labor has altered the approach to this problem, with increased focus on preventive strategies. Primary prevention is a limited strategy which involves public education, smoking cessation, improved nutritional status and avoidance of late preterm births. Secondary prevention focuses on recurrent preterm birth which is the most recognisable risk factor. Widely accepted strategies include cervical cerclage, progesterone and dedicated clinics. However, more research is needed to explore the role of antibiotics and anti-inflammatory treatments in the prevention of this complex problem.

We sought to use an innovative tool that is based on common biologic pathways to identify specific phenotypes among women with spontaneous preterm birth (SPTB) to enhance investigators' ability to identify and to highlight common mechanisms and underlying genetic factors that are responsible for SPTB. We performed a secondary analysis of a prospective case-control multicenter study of SPTB. All cases delivered a preterm singleton at SPTB ≤34.0 weeks' gestation. Each woman was assessed for the presence of underlying SPTB causes. A hierarchic cluster analysis was used to identify groups of women with homogeneous phenotypic profiles. One of the phenotypic clusters was selected for candidate gene association analysis with the use of VEGAS software. One thousand twenty-eight women with SPTB were assigned phenotypes. Hierarchic clustering of the phenotypes revealed 5 major clusters. Cluster 1 (n = 445) was characterized by maternal stress; cluster 2 (n = 294) was characterized by premature membrane rupture; cluster 3 (n = 120) was characterized by familial factors, and cluster 4 (n = 63) was characterized by maternal comorbidities. Cluster 5 (n = 106) was multifactorial and characterized by infection (INF), decidual hemorrhage (DH), and placental dysfunction (PD). These 3 phenotypes were correlated highly by χ(2) analysis (PD and DH, P cluster 3 of SPTB. We identified 5 major clusters of SPTB based on a phenotype tool and hierarch clustering. There was significant correlation between several of the phenotypes. The INS gene was associated with familial factors that were underlying SPTB. Copyright © 2015 Elsevier Inc. All rights reserved.

Objective: The search for quality, cost-effective health care programs in the United States is now a major focus in the era of health care reform. New programs need to be evaluated as alternatives are developed in the health care system. The BirthPlace program provides comprehensive perinatal services with certified nurse-midwives and obstetricians working together in an integrated collaborative practice serving a primarily low-income population. Low-risk women are delivered by nurse-midwives in a freestanding birth center (The BirthPlace), which is one component of a larger integrated health network. All others are delivered by team obstetricians at the affiliated tertiary hospital. Wellness, preventive measures, early intervention, and family involvement are emphasized. The San Diego Birth Center Study is a 4-year research project funded by the U.S. Federal Agency for Health Care Policy and Research (#R01-HS07161) to evaluate this program. The National Birth Center Study (NEJM, 1989; 321(26): 1801-11) described the advantages and safety of freestanding birth centers. However, a prospective cohort study with a concurrent comparison group of comparable risk had not been conducted on a collaborative practice-freestanding birth center model to address questions of safety, cost, and patient satisfaction.Methods: The specific aims of this study are to compare this collaborative practice model to the traditional model of perinatal health care (physician providers and hospital delivery). A prospective cohort study comparing these two health care models was conducted with a final expected sample size of approximately 2,000 birth center and 1,350 traditional care subjects. Women were recruited from both the birth center and traditional care programs (private physicians offices and hospital based clinics) at the beginning of prenatal care and followed through the end of the perinatal period. Prenatal, intrapartum, postpartum and infant morbidity and mortality are being

Trends in characteristics of women choosing contraindicated home births.

To characterize the American College of Obstetricians and Gynecologists (ACOG) contraindicated home births and the women who are receiving these births in hopes of identifying venues for intervention. The National Center for Health Statistics (NCHS) birth certificate records from 1990 to 2015 were used. "Planned home births" were defined as those births in which birthplace was coded as "residence" and birth attendant was coded as "certified nurse midwife (CNM)" or "other midwife". Contraindicated home births were defined as "planned home births" from 1990 to 2015 that had one or more of the ACOG risk factors for home births, which include vaginal birth after prior cesarean delivery (VBAC), breech presentation and multiple gestations. A review of trends in contraindicated home births from 1990 to 2015 suggests that they are increasing in number (481-1396) and as a percentage of total births (0.01%-0.04%, P95%), which is most frequently initiated in the first trimester. The majority of home births were paid out-of-pocket (65%-69%). The increasing number of contraindicated home births in the United States requires public health action. Home births are likely a matter of choice rather than a lack of resources. It is unclear if women choose home births while knowing the risk or due to a lack of information. Prenatal education about contraindicated home births is possible, as almost all women receive prenatal care.

Low birth weight in the United States.

Science.gov (United States)

Goldenberg, Robert L; Culhane, Jennifer F

2007-02-01

Pregnancy outcomes in the United States and other developed countries are considerably better than those in many developing countries. However, adverse pregnancy outcomes are generally more common in the United States than in other developed countries. Low-birth-weight infants, born after a preterm birth or secondary to intrauterine growth restriction, account for much of the increased morbidity, mortality, and cost. Wide disparities exist in both preterm birth and growth restriction among different population groups. Poor and black women, for example, have twice the preterm birth rate and higher rates of growth restriction than do most other women. Low birth weight in general is thought to place the infant at greater risk of later adult chronic medical conditions, such as diabetes, hypertension, and heart disease. Of interest, maternal thinness is a strong predictor of both preterm birth and fetal growth restriction. However, in the United States, several nutritional interventions, including high-protein diets, caloric supplementation, calcium and iron supplementation, and various other vitamin and mineral supplementations, have not generally reduced preterm birth or growth restriction. Bacterial intrauterine infections play an important role in the etiology of the earliest preterm births, but, at least to date, antibiotic treatment either before labor for risk factors such as bacterial vaginosis or during preterm labor have not consistently reduced the preterm birth rate. Most interventions have failed to reduce preterm birth or growth restriction. The substantial improvement in newborn survival in the United States over the past several decades is mostly due to better access to improved neonatal care for low-birth-weight infants.

Neonatal Bacteraemia Among 112,360 Live Births

LENUS (Irish Health Repository)

Huggard, D

2016-10-01

Our aims were to determine the incidence of bacteraemia in a cohort of neonatal patients over a 14 year period, to describe the organisms involved, and to establish the rates of sepsis with regard to both early onset sepsis (EOS) and late onset sepsis (LOS). Lastly, we investigated the trends of neonatal sepsis, to determine whether changes in clinical practice influenced the rate of blood culture positivity. With regards to EOS, GBS was the predominant pathogen, followed by E.coli, CoNS, and S. aureus . The overall mean EO rate per 1000 live births (LBs) was 1.19. Looking at LOS, S. aureus , CoNS , Enterococcus spp. were the most common bacteria cultured. The mean LOS rate was 1.88 per 1000 live births. The overall rate of EOS remained fairly steady. GBS remains the major pathogen in EOS; however its incidence has remained largely unchanged over time in relation to both EOS and LOS. Conversely the rate of LOS peaked from ’05-’09, mainly due to an increase in Staphylococcus aureus , CoNS and Enterococcus spp. cases, and then improved dramatically in the following years. This was likely due to a change in hospital policies in relation to hand hygiene and intravenous line placement and maintenance.

Variations in birth frequencies have an impact on activity planning in maternity wards. Previous studies of this phenomenon have commonly included elective births. A Danish study of spontaneous births found that birth frequencies were well modelled by a Poisson process. Somewhat unexpectedly, there were also weekly variations in the frequency of spontaneous births. Another study claimed that birth frequencies follow the Benford distribution. Our objective was to test these results. We analysed 50,017 spontaneous births at Akershus University Hospital in the period 1999-2014. To investigate the Poisson distribution of these births, we plotted their variance over a sliding average. We specified various Poisson regression models, with the number of births on a given day as the outcome variable. The explanatory variables included various combinations of years, months, days of the week and the digit sum of the date. The relationship between the variance and the average fits well with an underlying Poisson process. A Benford distribution was disproved by a goodness-of-fit test (p Poisson process when monthly and day-of-the-week variation is included. The frequency is highest in summer towards June and July, Friday and Tuesday stand out as particularly busy days, and the activity level is at its lowest during weekends.

A Role for the Liver in Parturition and Preterm Birth.

Science.gov (United States)

Mawson, Anthony R

Neither the mechanisms of parturition nor the pathogenesis of preterm birth are well understood. Poor nutritional status has been suspected as a major causal factor, since vitamin A concentrations are low in preterm infants. However, even large enteral doses of vitamin A from birth fail to increase plasma concentrations of vitamin A or improve outcomes in preterm and/or extremely low birthweight infants. These findings suggest an underlying impairment in the secretion of vitamin A from the liver, where about 80% of the vitamin is stored. Vitamin A accumulates in the liver and breast during pregnancy in preparation for lactation. While essential in low concentration for multiple biological functions, vitamin A in higher concentration can be pro-oxidant, mutagenic, teratogenic and cytotoxic, acting as a highly surface-active, membrane-seeking and destabilizing compound. Regarding the mechanism of parturition, it is conjectured that by nine months of gestation the hepatic accumulation of vitamin A (retinol) from the liver is such that mobilization and secretion are impaired to the point where stored vitamin A compounds in the form of retinyl esters and retinoic acid begin to spill or leak into the circulation, resulting in amniotic membrane destabilization and the initiation of parturition. If, however, the accumulation and spillage of stored retinoids reaches a critical threshold prior to nine months, e.g., due to cholestatic liver disease, which is common in mothers of preterm infants, the increased retinyl esters and/or retinoic acid rupture the fetal membranes, inducing preterm birth and its complications, including retinopathy, necrotizing enterocolitis and bronchopulmonary dysplasia. Subject to testing, the model suggests that measures taken prior to and during pregnancy to improve liver function could reduce the risk of adverse birth outcomes, including preterm birth.

The number of US women choosing home birth is increasing. Little is known about women who choose home birth after having experienced hospital birth; therefore, the purpose of this research was to explore reasons why these women choose home birth and their perceptions regarding their birth experiences. Qualitative description was the research design, whereby focus groups were conducted with women who had hospital births and subsequently chose home birth. Five focus groups were conducted (N = 20), recorded, and transcribed verbatim. Qualitative content analysis was undertaken allowing themes to emerge. Five themes emerged from the women's narratives: 1) choices and empowerment: with home birth, women felt they were given real choices rather than perceived choices, giving them feelings of empowerment; 2) interventions and interruptions: women believed things were done that were not helpful to the birth process, and there were interruptions associated with their hospital births; 3) disrespect and dismissal: participants believed that during hospital birth, providers were more focused on the laboring woman's uterus, with some experiencing dismissal from their hospital provider when choosing to birth at home; 4) birth space: giving birth in their own home, surrounded by people they chose, created a peaceful and calm environment; and 5) connection: women felt connected to their providers, families, newborns, and bodies during their home birth. For most participants, dissatisfaction with hospital birth influenced their subsequent decision to choose home birth. Despite experiencing challenges associated with this decision, women expressed satisfaction with their home birth. © 2014 by the American College of Nurse-Midwives.

to explore the prevalence of birth satisfaction for childbearing women planning to birth in their home or birth centers in the United States. Examining differences in birth satisfaction of the home and birth centers; and those who birthed in a hospital using the 30-item Birth Satisfaction Scale (BSS) and the 10-item Birth Satisfaction Scale-Revised (BSS-R). a quantitative survey using the BSS and BSS-R were employed. Additional demographic data were collected using electronic linkages (Qualtrics ™ ). a convenience sample of childbearing women (n=2229) who had planned to birth in their home or birth center from the US (United States) participated. Participants were recruited via professional and personal contacts, primarily their midwives. the total 30-item BSS score mean was 128.98 (SD 16.92) and the 10-item BSS-R mean score was 31.94 (SD 6.75). Sub-scale mean scores quantified the quality of care provision, women's personal attributes, and stress experienced during labour. Satisfaction was higher for women with vaginal births compared with caesareans deliveries. In addition, satisfaction was higher for women who had both planned to deliver in a home or a birth centre, and who had actually delivered in a home or a birth center. total and subscale birth satisfaction scores were positive and high for the overall sample IMPLICATIONS FOR PRACTICE: the BSS and the BSS-R provide a robust tool to quantify women's experiences of childbirth between variables such as birth types, birth settings and providers.

Thyroid disorders are common among reproductive-aged women, with hypothyroidism affecting 2 to 3% of pregnancies, and hyperthyroidism affecting an additional 0.1 to 1%. We examined associations between thyroid medications and individual birth defects using data from the National Birth Defects Prevention Study (NBDPS). The NBDPS is a multisite, population-based, case-control study that included pregnancies with estimated delivery dates from 1997 to 2011. We analyzed self-reported thyroid medication use from mothers of 31,409 birth defect cases and 11,536 unaffected controls. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression for birth defects with five or more exposed cases, controlling for maternal age, race/ethnicity, and study center. Crude ORs and exact 95% CIs were estimated for defects with 3 to 4 exposed cases. Thyroid hormone was used by 738 (2.3%) case and 237 (2.1%) control mothers, and was associated with anencephaly (OR = 1.68; 95% CI, 1.03-2.73), holoprosencephaly (OR = 2.48; 95% CI, 1.13-5.44), hydrocephaly (1.77; 95% CI, 1.07-2.95) and small intestinal atresia (OR = 1.81; 95% CI, 1.04-3.15). Anti-thyroid medication was used by 34 (0.1%) case and 10 (<0.1%) control mothers, and was associated with aortic valve stenosis (OR = 6.91; 95% CI, 1.21-27.0). While new associations were identified, our findings are relatively consistent with previous NBDPS analyses. Our findings suggest thyroid medication use is not associated with most birth defects studied in the NBDPS, but may be associated with some specific birth defects. These results should not be interpreted to suggest that medications used to treat thyroid disease are teratogens, as the observed associations may reflect effects of the underlying thyroid disease.

to study home, natural hospital, and medical hospital births, and the association of these birth models to resilience and birth experience. cross-section retrospective design. participants were recruited via an online survey system. Invitations to participate were posted in five different Internet forums for women on maternity leave, from September 2014 to August 2015. the sample comprised 381 post partum healthy women above the age of 20, during their maternity leave. Of the participants: 22% gave birth at home, 32% gave birth naturally in a hospital, and 46% of the participants had a medical birth at the hospital. life Orientation Test Revised (LOT-R), General Self-Efficacy Scale, Sense of Mastery Scale, Childbirth Experience Questionnaire (CEQ). women having had natural births, whether at home or at the hospital, significantly differed from women having had medical births in all aspects of the birth experience, even when controlling for age and optimism. Birth types contributed to between 14% and 24% of the explained variance of the various birth experience aspects. home and natural hospital births were associated with a better childbirth experience. Optimism was identified as a resilience factor, associated both with preference as well as with childbirth experience. physically healthy and resilient women could be encouraged to explore the prospect of home or natural hospital births as a means to have a more positive birth experience.

2016-01-01

Optimal birth spacing has health advantages for both mother and child. In developing countries, shorter birth intervals are common and associated with social, cultural, and economic factors, as well as a lack of family planning. This study investigated the first birth interval after marriage and preceding interbirth interval in Nepal. A community-based prospective cohort study was conducted in the Kaski district of Nepal. Information on birth spacing, demographic, and obstetric characteristics was obtained from 701 pregnant women using a structured questionnaire. Logistic regression analyses were performed to ascertain factors associated with short birth spacing. About 39% of primiparous women gave their first child birth within 1 year of marriage and 23% of multiparous women had short preceding interbirth intervals (gender equality in society.

Full Text Available Low birth weight (LBW and preterm birth are one the most important causes of death in the world and therefore are considered as one of the major health problems. Global statistics demonstrates an increase in the prevalence of low birth weight in the developing countries. Low birth weight infants are exposed to complications such as major neurosensory impairements, cerebral palsy, cognitive and language delays, neuromotor developmental delay, blindness and hearing loss, behavioral and psychosocial disorders, learning difficulties and dysfunction in scholastic performances. The majority of infant's death and developmental disorders were due to disorders relating to prematurity and unspecified low birth weight. Infants weighing less than 2500 g, is a major determinant of both neonatal and infant mortality rates and, together with congenital anomalies (e.g., cardiac, central nervous system, and respiratory, contributes significantly to childhood morbidity. Various studies indicate that low birth weight infants are suffering from physiological and psychosocial disabilities, two to three times more than the other children. At school age, preterm and low birth weight infants have poorer physical growth, cognitive function, and school performance. These disadvantages appear to persist into adulthood and therefore have broad implications for society. Although the survival rates have increased dramatically and the incidence of morbidities has decreased, the complications are still considered to be associated with economical and social burdens. Most children with Low birth weight suffer from multiple disabilities. Therefore, they need special and consistent care. On demand of reducing the infant mortality rate, the need to decrease the complications in low birth weight and preterm infants should be considered by the policy makers in health care system. In this review article, we assessed current evidences on developmental outcomes of low birth weight and

To explore the nature of birthing in United States (U.S.) hospitals from 1973-2007 and to explicate and interpret common, often overlooked, birthing experiences and nursing care. A Heideggerian phenomenological approach utilizing in-depth interviews. Participants' homes in Washington, Idaho, and Oregon. A purposive sample of grand multiparaes (N = 14). Data were collected via open conversational interviews of 60-90 minutes recorded on digital media and completion of a demographic and birth attribute form. Field notes and interpretive commentary were used as additional data sources and were analyzed using an established Heideggerian approach. The participants came from diverse religious and ethical backgrounds and experienced 116 births (8.29 births per woman, 79% unmedicated), a Cesarean rate of 6%, and a breastfeeding rate of 99% with a mean duration of 12 months. Two overarching patterns emerged: pursuing the "'good birth": a safe passage for baby and being in-and-out of control: body, technology, others. Each pattern subsumed several overlapping themes. The first pattern revealed that women often desire a good birth in the safety of a hospital by navigating their options prior to and during the birth. The second pattern revealed a common, yet often unachievable, desire by all of those involved in the process to control birth. Harmonizing an exchange of ideas in a technologically advanced environment prevalent in hospitals today can increase the quality of intrapartum care. Encouraging anchored companions and promoting normal physiological birth will make hospitals places where women can experience a good birth and feel safe. © 2011 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

2011-09-01

The aim was to identify the proportion of fathers having a positive experience of a normal birth and to explore factors related to midwifery care that were associated with a positive experience. Research has mainly focused on the father's supportive role during childbirth rather than his personal experiences of birth. 595 new fathers living in a northern part of Sweden, whose partner had a normal birth, were included in the study. Data was collected by questionnaires. Odds Ratios with 95% confidence interval and logistic regression analysis were used. The majority of fathers (82%) reported a positive birth experience. The strongest factors associated with a positive birth experience were midwife support (OR 4.0; 95 CI 2.0-8.1), the midwife's ongoing presence in the delivery room (OR 2.0; 1.1-3.9), and information about the progress of labour (OR 3.1; 1.6-5.8). Most fathers had a positive birth experience. Midwifery support, the midwife's presence and sufficient information about the progress of labour are important aspects in a father's positive birth experience. The role of the midwife during birth is important to the father, and his individual needs should be considered in order to enhance a positive birth experience.

Abstract Background: As reflected in the United Nations Millennium Development Goals (UN MDG 5), reducing maternal mortality represents an important area of concern. The common causes of maternal deaths may be preventable and treatable by having access to emergency obstetric care (EmOC), including skilled birth attendance (SBA), when needed. Measuring the presence of a birth attendant has been the main focus until now, not their skills and qualifications, and by this we cannot presuppose ...

Agricultural Compounds in Water and Birth Defects.

Science.gov (United States)

Brender, Jean D; Weyer, Peter J

2016-06-01

Agricultural compounds have been detected in drinking water, some of which are teratogens in animal models. The most commonly detected agricultural compounds in drinking water include nitrate, atrazine, and desethylatrazine. Arsenic can also be an agricultural contaminant, although arsenic often originates from geologic sources. Nitrate has been the most studied agricultural compound in relation to prenatal exposure and birth defects. In several case-control studies published since 2000, women giving birth to babies with neural tube defects, oral clefts, and limb deficiencies were more likely than control mothers to be exposed to higher concentrations of drinking water nitrate during pregnancy. Higher concentrations of atrazine in drinking water have been associated with abdominal defects, gastroschisis, and other defects. Elevated arsenic in drinking water has also been associated with birth defects. Since these compounds often occur as mixtures, it is suggested that future research focus on the impact of mixtures, such as nitrate and atrazine, on birth defects.

Lang, Cathleen A; Cox, Matthew J; Flores, Glenn

2013-12-01

The rate of multiple births has increased over the last two decades. In 1982, an increased frequency of injuries among this patient population was noted, but few studies have evaluated the increased incidence of maltreatment in twins. The study aim was to evaluate the features of all multiple-birth children with substantiated physical abuse and/or neglect over a four-year period at a major children's hospital. A Retrospective chart review was conducted of multiple-gestation children in which at least one child in the multiple set experienced child maltreatment from January 2006 to December 2009. Data regarding the child, injuries, family, and perpetrators were abstracted. We evaluated whether family and child characteristics were associated with maltreatment, and whether types of injuries were similar within multiple sets. For comparison, data from the same time period for single-birth maltreated children also were abstracted, including child age, gestational age at birth, and injury type. There were 19 sets of multiple births in which at least one child had abusive injuries and/or neglect. In 10 of 19 sets (53%), all multiples were found to have a form of maltreatment, and all children in these multiple sets shared at least one injury type. Parents lived together in 63% of cases. Fathers and mothers were the alleged perpetrator in 42% of the cases. Multiple-gestation-birth maltreated children were significantly more likely than single-birth maltreated children to have abdominal trauma (13% vs. 1%, respectively; pchildren often, but not always, were abused. In sets with two maltreated children, children usually shared the same modes of maltreatment. Multiples are significantly more likely than singletons to be younger and experience fractures and abdominal trauma. The findings support the current standard practice of evaluating all children in a multiple set when one is found to be abused or neglected. Copyright © 2013 Elsevier Ltd. All rights reserved.

Near miss and minor occupational injury: Does it share a common causal pathway with major injury?

2009-01-01

An essential assumption of injury prevention programs is the common cause hypothesis that the causal pathways of near misses and minor injuries are similar to those of major injuries. The rates of near miss, minor injury and major injury of all reported incidents and musculoskeletal incidents (MSIs) were calculated for three health regions using information from a surveillance database and productive hours from payroll data. The relative distribution of individual causes and activities involved in near miss, minor injury and major injury were then compared. For all reported incidents, there were significant differences in the relative distribution of causes for near miss, minor, and major injury. However, the relative distribution of causes and activities involved in minor and major MSIs were similar. The top causes and activities involved were the same across near miss, minor, and major injury. Finding from this study support the use of near miss and minor injury data as potential outcome measures for injury prevention programs. (c) 2008 Wiley-Liss, Inc.

Yanni, Emad A; Copeland, Glenn; Olney, Richard S

2010-06-01

Birth defects and genetic disorders are leading causes of infant morbidity and mortality in many countries. Population-based data on birth defects among Arab-American children have not been documented previously. Michigan has the second largest Arab-American community in the United States after California. Using data from the Michigan Birth Defects Registry (MBDR), which includes information on parents' country of birth and ancestry, birth prevalences were estimated in offspring of Michigan women of Arab ancestry for 21 major categories of birth defects and 12 congenital endocrine, metabolic, and hereditary disorders. Compared with other non-Hispanic white children in Michigan, Arab-American children had similar or lower birth prevalences of the selected types of structural birth defects, with higher rates of certain hereditary blood disorders and three categories of metabolic disorders. These estimates are important for planning preconception and antenatal health care, genetic counseling, and clinical care for Arab Americans.

Experiences of South African multiparous labouring women using the birthing ball to encourage vaginal births

Sindiwe James

2017-10-01

Full Text Available The article explores the experiences of South African multiparous labouring women on their use of the birthing ball during the first stage of labour. The authors used a qualitative research approach using unstructured audiotaped interviews as the data collection method and data were collected over a period of one calendar month. The sample for the study were women who were six hours to six weeks post-delivery, had at least one child already, used the birthing ball, were on no medication, and had delivered a live infant. The sample consisted of twelve purposively selected participants, two of whom were used for the pilot study. The data analysis method was Data Analysis Spiral. The authors made use of an independent coder to assist with coding the data and three major themes were identified. The results revealed that the labouring women experienced the birthing ball as a useful labour tool, as shortening the labour process and as empowering them during labour.

Full Text Available This study investigates the relation between birth order (BO, birth weight (BW0, colostrum intake (CI, level of passive immunity and pre-weaning mortality of piglets. The animals used were 551 cross-bred piglets [Piétrain × (Large-White × Landrace] born from 40 sows. Colostrum immunoglobulins G (IgG determinations were made from 17 sows. Colostrum samples were obtained at birth of the first piglet then at 3, 6, 12, 24, and 36 h later, and on the first-two and the last-two piglets born. Serum IgG determinations from 68 piglets were made at 2d of age and at weaning. Individual CI was estimated from body weight gain. Relative birth order (RBO and BW0 within-litter were weakly (R20.10 but increased by 26 ± 1.6 g per 100 g increase in BW0 (p0.10. It was concluded that despite last-born piglets obtained less passive immunity than first-born, they were not at higher risk of dying before weaning. Major causes of mortality were low birth weight and insufficient colostrum (energy intake.

The joy at birth: an interpretive hermeneutic literature review.

Science.gov (United States)

Crowther, Susan; Smythe, Elizabeth; Spence, Deb

2014-04-01

this literature review examines the experience of joy at birth and what that joy means. The premise is that the whole of the birthing experience has not been fully explicated in the literature and that something of significance remains unexplored and unspoken. It is argued that a hermeneutic phenomenological approach to reviewing literature provides unique insights and leads to deeper understandings about birth and the experience of joy that attunes at that moment. the philosophical underpinnings informed by Heidegger and Gadamer are central to this review and therefore the process of reviewing literature hermeneutically is described. Heideggerian phenomenology is used as the method to ask the questions of the literature in order that concealed and hidden experiences of joy at birth are made visible where they are gleaned from the literature. A hermeneutic lens is used to uncover relationships within the phenomenon of joy at birth and meaning. although a vast birth literature was reviewed joy at birth was often ignored, hidden or covered over. Reviewing the literature on relationships, professional presence, place of birth, birth satisfaction studies and birth as peak and spiritual experience provides glimpses of the phenomenon 'joy at birth'. it is argued that joy at birth remains largely neglected as a phenomenon worthy of consideration. Plausible interpretations are presented that suggest that joy at birth points to something significant and meaningful. Spiritual and sacred meaning is alluded to in the papers reviewed yet the majority of papers that investigate birth leave this meaning unspoken. The review highlights a need for further thinking and questioning about birth that would direct on-going investigation. Copyright © 2014 Elsevier Ltd. All rights reserved.

To examine the associations of: (a) neonatal sex with mild-to-moderate and severe birth asphyxia, (b) fetal sex with mortality due to birth asphyxia and (c) neonatal race with severe birth asphyxia. We used the Nationwide Inpatient Sample (NIS) Database including the years 1993 to 2008 or its pediatric sub portion Kid's Inpatient Database (KID) for the years 1997, 2000, 2003 and 2006. NIS database is collected annually from more than 1000 hospitals across the United States for millions of inpatient discharge summaries. We included newborns older than 36 weeks gestational age or more than 2500 g at birth. We excluded newborns with congenital heart disease, major congenital anomalies and chromosomal disorders. We compared birth asphyxia in males to females, and in each race compared with whites, and examined effect of sex in association with birth asphyxia within each race/ethnicity. There were 9 708 251 term infants (51.8% males) included in the study. There were 15 569 newborns diagnosed with severe birth asphyxia (1.6 in 1000); of them 56.1% were males. Odds ratio (OR)to have severe birth asphyxia in male newborns was 1.16 (confidence interval (CI): 1.12 to 1.20, Psex was associated with increased birth asphyxia in all races but Native American. Male sex and African-American race were associated with increased prevalence of birth asphyxia.

Finding Autonomy in Birth*

2009-01-01

Over the last several years, as cesarean deliveries have grown increasingly common, there has been a great deal of public and professional interest in the phenomenon of women ‘choosing’ to deliver by cesarean section in the absence of any specific medical indication. The issue has sparked intense conversation, as it raises questions about the nature of autonomy in birth. Whereas mainstream bioethical discourse is used to associating autonomy with having a large array of choices, this conception of autonomy does not seem adequate to capture concerns and intuitions that have a strong grip outside of this discourse. An empirical and conceptual exploration of how delivery decisions ought to be negotiated must be guided by a rich understanding of women’s agency and its placement within a complicated set of cultural meanings and pressures surrounding birth. It is too early to be ‘for’ or ‘against’ women’s access to cesarean delivery in the absence of traditional medical indications - and indeed, a simple pro- or con- position is never going to do justice to the subtlety of the issue. The right question is not whether women ought to be allowed to choose their delivery approach, but rather, taking the value of women’s autonomy in decision-making around birth as a given, what sorts of guidelines, practices, and social conditions will best promote and protect women’s full inclusion in a safe and positive birth process.

Full Text Available Traditional Birth Attendants (TBAs and traditional healers form an important link in the chain of health personnel providing primary health care in Malawi. In spite of the establishment of hospitals and health centres, it is to these traditional healers and TBAs that the majority of people turn in times of sickness and child-birth. Approximately 60 percent of all deliveries in Malawi occur in the villages. It is therefore important that due regard be paid to the activities of these traditional practitioners in order to ensure the achievement of the goal - "Health for all by the year 2000". The training of TBAs is seen as part of the Maternal and Child Health Services in the country.

Exposure to air pollution is linked with an increased risk of preterm births. To provide further evidence on this relationship, we evaluated the association between proximity to major roads--as an index for air pollution exposure--and various obstetrical complications. Data were extracted from a database maintained by the perinatal hospital in Shizuoka, Japan. We restricted the analysis to mothers with singleton pregnancies of more than 22 weeks of gestation from 1997 to 2012 (n=19,077). Using the geocoded residential information, each mother was assigned proximity to major roads. We then estimated multivariate adjusted odds ratios and their 95% confidence intervals (CIs) for the effects of proximity to major roads on various obstetrical complications (preeclampsia, gestational diabetes mellitus, placenta abruption, placenta previa, preterm premature rupture of membrane (pPROM), preterm labor, and preterm births). We found positive associations of proximity to major roads with preeclampsia and pPROM. Living within 200 m increased the odds of preeclampsia by 1.3 times (95% CI, 1.0-1.8) and pPROM by 1.6 times (95% CI, 1.1-2.2). Furthermore, living within 200 m increased the odds of preterm births by 1.4 fold (95% CI, 1.2-1.7). Exposure to traffic-related air pollution increased the risk of preeclampsia and pPROM in this study. We propose a mechanism responsible for the association between air pollution and preterm births.

A survey was carried out in Ribeirão Preto, S. Paulo State, Brazil, between June 1978 and May 1979 with a view to studying the prevalence of low birth weight and its occurrence among different social classes. Data were collected from 8,878 singleton live births in eight maternity hospitals, accounting for 98% of all births in the area. Social classes were determinated by the use of a model proposed by Singer and modified for epidemiological purposes by Barros. Out of the 8,878 births, 660 (7.5%) were of low birth weight. The prevalence of deficient weight at birth (between 2,500 and 2,999 grams) was of 21.1%. Analysis indicated that 50.6% of children with low birth weight were at term and the majority of them suffered form intrauterine growth retardation. The prevalence of low birth weight according to social class was seen to be lower in the bourgeoisie classes (ranging from 2.8% to 3.9%) and higher in working classes (from 7% up to 9.5%). Low birth weight (defined as less than or equal to 2,500 grams) was used for purposes of comparison with other previous surveys. The percentage was lower in this study (8.3%) than that found in the Interamerican Investigation of Mortality in Childhood (8.7%), carried out in 1968-70. No statistically significant differences in the percentage of low birth weight were found in the case of Ribeirão Preto when these two surveys were compared.

To evaluate recent trends of out-of-hospital births in the US from 2009 to 2014. We accessed data for all live births occurring in the US from the National Vital Statistics System, Natality Data Files for 2009-2014 through the interactive data tool, VitalStats. Out-of-hospital (OOH) births in the US increased from 2009 to 2014 by 80.2% from 32,596 to 58,743 (0.79%-1.47% of all live births). Home births (HB) increased by 77.3% and births in freestanding birthing centers (FBC) increased by 79.6%. In 2014, 63.8% of OOH births were HB, 30.7% were in FBC, and 5.5% were in other places, physicians offices, or clinics. The majority of women who had an OOH birth in 2014 were non-Hispanic White (82.3%). About in one in 47 non-Hispanic White women had an OOH in 2014, up from 1 in 87 in 2009. Women with a HB were older compared to hospital births (age ≥35: 21.5% vs. 15.4%), had a higher live birth order(≥5: 18.9% vs. 4.9%), 3.48% had infants home and in freestanding birthing centers has significantly increased in the US making it the country with the most out of hospital births among all developed countries. The root cause of the increase in planned OOH births should be identified and addressed by the medical community.

Primate pelvic anatomy and implications for birth

Science.gov (United States)

Trevathan, Wenda

2015-01-01

The pelvis performs two major functions for terrestrial mammals. It provides somewhat rigid support for muscles engaged in locomotion and, for females, it serves as the birth canal. The result for many species, and especially for encephalized primates, is an ‘obstetric dilemma’ whereby the neonate often has to negotiate a tight squeeze in order to be born. On top of what was probably a baseline of challenging birth, locomotor changes in the evolution of bipedalism in the human lineage resulted in an even more complex birth process. Negotiation of the bipedal pelvis requires a series of rotations, the end of which has the infant emerging from the birth canal facing the opposite direction from the mother. This pattern, strikingly different from what is typically seen in monkeys and apes, places a premium on having assistance at delivery. Recently reported observations of births in monkeys and apes are used to compare the process in human and non-human primates, highlighting similarities and differences. These include presentation (face, occiput anterior or posterior), internal and external rotation, use of the hands by mothers and infants, reliance on assistance, and the developmental state of the neonate.

To explore common biological pathways for attention deficit hyperactivity disorder (ADHD) and low birth weight (LBW). Thei-Gsea4GwasV2 software was used to analyze the result of genome-wide association analysis (GWAS) for LBW (pathways were derived from Reactome), and nominally significant (Ppathways were tested for replication in ADHD.Significant pathways were analyzed with DAPPLE and Reatome FI software to identify genes involved in such pathways, with each cluster enriched with the gene ontology (GO). The Centiscape2.0 software was used to calculate the degree of genetic networks and the betweenness value to explore the core node (gene). Weighed gene co-expression network analysis (WGCNA) was then used to explore the co-expression of genes in these pathways.With gene expression data derived from BrainSpan, GO enrichment was carried out for each gene module. Eleven significant biological pathways was identified in association with LBW, among which two (Selenoamino acid metabolism and Diseases associated with glycosaminoglycan metabolism) were replicated during subsequent ADHD analysis. Network analysis of 130 genes in these pathways revealed that some of the sub-networksare related with morphology of cerebellum, development of hippocampus, and plasticity of synaptic structure. Upon co-expression network analysis, 120 genes passed the quality control and were found to express in 3 gene modules. These modules are mainly related to the regulation of synaptic structure and activity regulation. ADHD and LBW share some biological regulation processes. Anomalies of such proces sesmay predispose to ADHD.

Association between antibiotic use among pregnant women with urinary tract infections in the first trimester and birth defects, National Birth Defects Prevention Study 1997 to 2011.

Previous studies noted associations between birth defects and some antibiotics (e.g., nitrofurantoin, sulfonamides) but not others (e.g., penicillins). It is unclear if previous findings were due to antibiotic use, infections, or chance. To control for potential confounding by indication, we examined associations between antibiotic use and birth defects, among women reporting urinary tract infections (UTIs). The National Birth Defects Prevention Study is a multi-site, population-based case-control study. Case infants/fetuses have any of over 30 major birth defects and controls are live-born infants without major birth defects. We analyzed pregnancies from 1997 to 2011 to estimate the association between maternally reported periconceptional (month before conception through the third month of pregnancy) use of nitrofurantoin, trimethoprim-sulfamethoxazole, or cephalosporins and specific birth defects, among women with periconceptional UTIs. Women with periconceptional UTIs who reported penicillin use served as the comparator. Periconceptional UTIs were reported by 7.8% (2029/26,068) of case and 6.7% (686/10,198) of control mothers. Most (68.2% of case, 66.6% of control mothers) also reported antibiotic use. Among 608 case and 231 control mothers reporting at least one periconceptional UTI and certain antibiotic use, compared with penicillin, nitrofurantoin use was associated with oral clefts in the offspring (adjusted odds ratio, 1.97 [95% confidence interval, 1.10-3.53]), trimethoprim-sulfamethoxazole use with esophageal atresia (5.31 [1.39-20.24]) and diaphragmatic hernia (5.09 [1.20-21.69]), and cephalosporin use with anorectal atresia/stenosis (5.01 [1.34-18.76]). Periconceptional exposure to some antibiotics might increase the risk for certain birth defects. However, because individual birth defects are rare, absolute risks should drive treatment decisions.Birth Defects Research (Part A) 106:940-949, 2016.© 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals

Full Text Available Racial disparity in preterm is a major problem in the US. Although significant strides have been made in identifying some of the risk factors, the complexities between community and individual factors are not understood. This study examines the influence of individual and community level factors affecting preterm birth among Black and White women in an urban setting. A 10-year live birth registry dataset from a mid-sized, racially diverse city was analyzed (N = 30,591. Data were geocoded and merged with block group level Census data. Five hierarchical models were examined using PROC GLIMMIX. Education, illicit drug use, pregnancy complications, previous preterm birth, paternal presence, inadequate and adequate plus prenatal care, and poverty were associated with preterm births in both Blacks and Whites. In Black women, increasing maternal age, maternal smoking, and a previous infant death were significant predictors of preterm births, which was not the case for White women. Residing in medium or high poverty neighborhoods resulted in 19% and 28% higher odds, respectively, of preterm birth for Black women. In addition to individual level factors, neighborhood poverty is an important risk factor influencing preterm birth. It is essential to engage multisectoral agencies in addressing factors influencing preterm birth.

Overview of results and perspectives from the Shoreham major common-cause initiating events study

1986-01-01

This study represents the continuation of a large effort by LILCO to fully understand the potential hazards posed by future operation of the Shoreham Nuclear Power Stations (SNPS). The Shoreham Probabilistic Risk Assessment, a level 3 PRA without external events, provided a characterization of the accident sequences that could leave the core in a condition in which it would be vulnerable to severe damage if further mitigating actions were not taken. It estimated the frequency and magnitude of the potential radioactivity releases associated with such sequences. The study was limited to accident sequences initiated by so called internal events to the plant including a loss of offsite power. It also characterized the public risk associated with those accident sequences. The ''Major Common-Cause Initiating Events Study'' (MCCI) for the Shoreham plant was performed to obtain insights into the plant's susceptibility to, and inherent defenses against, certain MCCIs. Major common-cause initiating events are occurrences which have the potential to initiate a plant transient or LOCA and, also, damage one or more plant systems needed to mitigate the effects of a transient or LOCA. The scope of the MCCI study included detailed analyses of seismic events and fires through the severe core damage and bounding analyses of aircraft crashes, windstorms, turbine missiles and release of hazardous materials near the plant

Extubation failure is one of the most serious complications in extremely low birth weight infants (ELBWI) on mechanical ventilation therapy. We performed a 5-year retrospective analysis to realize the status of extubation failure in ELBWI. Extubation failure was defined as requirements of re-intubation within 72 hours after extubation. The extubation failure rate was 21% (29/138). The mean birth body weight was 808.3 +/- 140.4 gm. The mean gestational age was 25.8 +/- 1.2 wks. The incidence of chronic lung disease (CLD) in infants with extubation failure was 100% (29/29). Apnea of prematurity 49% (14/29) and post-extubation atelectasis 39% (11/29) were the most common reasons for reintubation. The major microbiology findings which correlated with nosocomial pneumonia in infants with extubation failure were Acinetobacter baumanni (21%), Klebsiella pneumonia (21%), Pseudomonas aeroginosa (14%), and Methicillin resistant staphylococcus aureus (14%). In conclusion, post-extubation atelectasis and apnea were the most common reasons for reintubation. ELBWI with extubation failure had higher incidences of post-extubation atelectasis, CLD, and nosocomial pneumonia. Further prospective studies are needed in order to clarify the appropriate extubation program for ELBWI and to prevent post-extubation atelectasis and nosocomial pneumonia.

Birth order and mortality: a population-based cohort study.

Science.gov (United States)

Barclay, Kieron; Kolk, Martin

2015-04-01

This study uses Swedish population register data to investigate the relationship between birth order and mortality at ages 30 to 69 for Swedish cohorts born between 1938 and 1960, using a within-family comparison. The main analyses are conducted with discrete-time survival analysis using a within-family comparison, and the estimates are adjusted for age, mother's age at the time of birth, and cohort. Focusing on sibships ranging in size from two to six, we find that mortality risk in adulthood increases with later birth order. The results show that the relative effect of birth order is greater among women than among men. This pattern is consistent for all the major causes of death but is particularly pronounced for mortality attributable to cancers of the respiratory system and to external causes. Further analyses in which we adjust for adult socioeconomic status and adult educational attainment suggest that social pathways only mediate the relationship between birth order and mortality risk in adulthood to a limited degree.

Schooling, marriage, and age at first birth in Madagascar.

Glick, Peter; Handy, Christopher; Sahn, David E

2015-01-01

The low school attainment, early marriage, and low age at first birth of females are major policy concerns in less developed countries. This study jointly estimated the determinants of educational attainment, marriage age, and age at first birth among females aged 12-25 in Madagascar, explicitly accounting for the endogeneities that arose from modelling these related outcomes simultaneously. An additional year of schooling results in a delay to marriage of 1.5 years and marrying 1 year later delays age at first birth by 0.5 years. Parents' education and wealth also have important effects on schooling, marriage, and age at first birth, with a woman's first birth being delayed by 0.75 years if her mother had 4 additional years of schooling. Overall, our results provide rigorous evidence for the critical role of education-both individual women's own and that of their parents-in delaying the marriage and fertility of young women.

Associations of meteorology with adverse pregnancy outcomes: a systematic review of preeclampsia, preterm birth and birth weight.

Science.gov (United States)

Beltran, Alyssa J; Wu, Jun; Laurent, Olivier

2013-12-20

The relationships between meteorology and pregnancy outcomes are not well known. This article reviews available evidence on the relationships between seasonality or meteorology and three major pregnancy outcomes: the hypertensive disorders of pregnancy (including preeclampsia, eclampsia and gestational hypertension), gestational length and birth weight. In total 35, 28 and 27 studies were identified for each of these outcomes. The risks of preeclampsia appear higher for women with conception during the warmest months, and delivery in the coldest months of the year. Delivery in the coldest months is also associated with a higher eclampsia risk. Patterns of decreased gestational lengths have been observed for births in winter, as well as summer months. Most analytical studies also report decreases in gestational lengths associated with heat. Birth weights are lower for deliveries occurring in winter and in summer months. Only a limited number of studies have investigated the effects of barometric pressure on gestational length or the effects of temperature and sunshine exposure on birth weight, but these questions appear worth investigating further. Available results should encourage further etiological research aiming at enhancing our understanding of the relationships between meteorology and adverse pregnancy outcomes, ideally via harmonized multicentric studies.

Birth weight and stuttering: Evidence from three birth cohorts.

Previous studies have produced conflicting results with regard to the association between birth weight and developmental stuttering. This study sought to determine whether birth weight was associated with childhood and/or adolescent stuttering in three British birth cohort samples. Logistic regression analyses were carried out on data from the Millenium Cohort Study (MCS), British Cohort Study (BCS70) and National Child Development Study (NCDS), whose initial cohorts comprised over 56,000 individuals. The outcome variables were parent-reported stuttering in childhood or in adolescence; the predictors, based on prior research, were birth weight, sex, multiple birth status, vocabulary score and mother's level of education. Birth weight was analysed both as a categorical variable (low birth weight, stuttering during childhood (age 3, 5 and 7 and MCS, BCS70 and NCDS, respectively) or at age 16, when developmental stuttering is likely to be persistent. None of the multivariate analyses revealed an association between birth weight and parent-reported stuttering. Sex was a significant predictor of stuttering in all the analyses, with males 1.6-3.6 times more likely than females to stutter. Our results suggest that birth weight is not a clinically useful predictor of childhood or persistent stuttering. Copyright © 2013 Elsevier Inc. All rights reserved.

Assessing neural commonalities and differences among depression, anxiety and their comorbidity is critical in developing a more integrative clinical neuroscience and in evaluating currently debated categorical vs dimensional approaches to psychiatric classification. Therefore, in this study, we sought to identify patterns of anomalous neural responding to criticism and praise that are specific to and common among major depressive disorder (MDD), social anxiety disorder (SAD) and comorbid MDD-SAD. Adult females who met formal diagnostic criteria for MDD, SAD or MDD-SAD and psychiatrically healthy participants underwent functional magnetic resonance imaging as they listened to statements directing praise or criticism at them or at another person. MDD groups showed reduced responding to praise across a distributed cortical network, an effect potentially mediated by thalamic nuclei undergirding arousal-mediated attention. SAD groups showed heightened anterior insula and decreased default-mode network response to criticism. The MDD-SAD group uniquely showed reduced responding to praise in the dorsal anterior cingulate cortex. Finally, all groups with psychopathology showed heightened response to criticism in a region of the superior frontal gyrus implicated in attentional gating. The present results suggest novel neural models of anhedonia in MDD, vigilance-withdrawal behaviors in SAD, and poorer outcome in MDD-SAD. Importantly, in identifying unique and common neural substrates of MDD and SAD, these results support a formulation in which common neural components represent general risk factors for psychopathology that, due to factors that are present at illness onset, lead to distinct forms of psychopathology with unique neural signatures. © The Author (2014).

To obtain the low birth weight (LBW) rate, the very low birth weight (VLBW) rate, and gestational age (GA)-specific birth weight distribution based on a large population in Korea, we collected and analyzed the birth data of 108,486 live births with GA greater than 23 weeks for 1 yr from 1 January to 31 December 2001, from 75 hospitals and clinics located in Korea. These data included birth weight, GA, gender of the infants, delivery type, maternal age, and the presence of multiple pregnancy. The mean birth weight and GA of a crude population are 3,188 +/-518 g and 38.7+/-2.1 weeks, respectively. The LBW and the VLBW rates are 7.2% and 1.4%, respectively. The preterm birth rate (less than 37 completed weeks of gestation) is 8.4% and the very preterm birth rate (less than 32 completed weeks of gestation) is 0.7%. The mean birth weights for female infants, multiple births, and births delivered by cesarean section were lower than those for male, singletons, and births delivered vaginally. The risk of delivering LBW or VLBW infant was higher for the teenagers and the older women (aged 35 yr and more). We have also obtained the percentile distribution of GA-specific birth weight in infants over 23 weeks of gestation.

Poor birth weight recovery among low birth weight/preterm infants following hospital discharge in Kampala, Uganda

Namiiro Flavia B

2012-01-01

Full Text Available Abstract Background Healthy infants typically regain their birth weight by 21 days of age; however, failure to do so may be due to medical, nutritional or environmental factors. Globally, the incidence of low birth weight deliveries is high, but few studies have assessed the postnatal weight changes in this category of infants, especially in Africa. The aim was to determine what proportion of LBW infants had not regained their birth weight by 21 days of age after discharge from the Special Care Unit of Mulago hospital, Kampala. Methods A cross sectional study was conducted assessing weight recovery of 235 LBW infants attending the Kangaroo Clinic in the Special Care Unit of Mulago Hospital between January and April 2010. Infants aged 21 days with a documented birth weight and whose mothers gave consent to participate were included in the study. Baseline information was collected on demographic characteristics, history on pregnancy, delivery and postnatal outcome through interviews. Pertinent infant information like gestation age, diagnosis and management was obtained from the medical records and summarized in the case report forms. Results Of the 235 LBW infants, 113 (48.1% had not regained their birth weight by 21 days. Duration of hospitalization for more than 7 days (AOR: 4.2; 95% CI: 2.3 - 7.6; p value Conclusion Failure to regain birth weight among LBW infants by 21 days of age is a common problem in Mulago Hospital occurring in almost half of the neonates attending the Kangaroo clinic. Currently, the burden of morbidity in this group of high-risk infants is undetected and unaddressed in many developing countries. Measures for consideration to improve care of these infants would include; discharge after regaining birth weight and use of total parenteral nutrition. However, due to the pressure of space, keeping the baby and mother is not feasible at the moment hence the need for a strong community system to boost care of the infant. Close

The relationship between preterm birth and underweight in Asian women.

Science.gov (United States)

Neggers, Yasmin H

2015-08-15

Although vast improvements have been made in the survival of preterm infants, the toll of preterm birth (PTB) is particularly severe in Asia, with the Indian subcontinent leading the preterm birth rate. Despite the obesity epidemic, maternal underweight remains a common occurrence in developing countries. An association between maternal underweight and preterm birth has been reported in developed countries. A review of epidemiological studies in Asian women in whom association between maternal body mass index (BMI) and risk of PTB was measured, indicated no significant association between low maternal BMI and preterm birth. A hindrance in comparison of these studies is the use of different cut-off point for BMI in defining maternal underweight. As a commentary on published studies it is proposed that that country-specific BMI cut points should be applied for defining underweight for Asian women for the purpose of evaluating the association between maternal underweight and preterm birth.

It employed a descriptive research design. The respondents were 50 Maranao TBAs selected through the snowball sampling technique. A questionnaire was developed by the researchers to identify the respondents’ modern birthing practices utilizing the Essential Intrapartum and Newborn Care (EINC Protocol. To determine their profile and traditional birthing practices, items from a previous study and the respondents’ personal claims were adapted. This study shows that Maranao TBAs have less compliance to the EINC Protocol and they often practice the traditional birthing interventions, thus increasing the risk of complications to both mother and newborn.

Dietary Patterns and Birth Weight—a Review

Directory of Open Access Journals (Sweden)

Marte K.R. Kjøllesdal

2014-11-01

Full Text Available Being born with low birth weight (LBW is recognized as a disadvantage due to risk of early growth retardation, fast catch up growth, infectious disease, developmental delay, and death during infancy and childhood, as well as development of obesity and non-communicable diseases (NCDs later in life. LBW is an indicator of fetal response to a limiting intrauterine environment, which may imply developmental changes in organs and tissue. Numerous studies have explored the effect of maternal intake of various nutrients and specific food items on birth weight (BW. Taking into account that people have diets consisting of many different food items, extraction of dietary patterns has emerged as a common way to describe diets and explore the effects on health outcomes. The present article aims to review studies investigating the associations between dietary patterns derived from a posteriori analysis and BW, or being small for gestational age (SGA. A PubMed search was conducted with the Mesh terms “pregnancy” OR “fetal growth retardation” OR “fetal development” OR “infant, small for gestational age” OR “birth weight” OR “infant, birth weight, low” AND “diet” OR “food habits”. Final number of articles included was seven, all which assessed diet by use of food frequency questionnaire (FFQ. Five studies explored dietary patterns using principal component analyses (PCA, while one study used cluster analyses and one study logistic regression. The studies reported between one and seven dietary patterns. Those patterns positively associated with BW were labeled “nutrient dense”, “protein rich”, “health conscious”, and “Mediterranean”. Those negatively associated with BW were labeled “Western”, “processed”, “vegetarian”, “transitional”, and “wheat products”. The dietary patterns “Western” and “wheat products” were also associated with higher risk of SGA babies, whereas a �

[Home births].

Welffens, K; Kirkpatrick, C; Daelemans, C; Derisbourg, S

In Belgium, very few women give birth outside the delivery room. In the United Kingdom and in the Netherlands, they are more numerous. Several studies evaluated obstetric and neonatal outcomes of home births compared with hospital births. We selected seven recent and large studies (with cohorts of more than 5.000 women) using PubMed, Science Direct and Cochrane Database of Systematic Reviews. Several questions were examined. Is there any difference in maternal and neonatal outcomes depending on the intended place of birth? Does parity affect outcomes ? What are the characteristics of women who choose to deliver at home ? We conclude that giving birth at home improves obstetric outcomes but is riskier for the baby, especially for the first one. The women delivering at home are mainly white Europeans, between 25 and 35 years old, in a relationship, multiparous and wealthier. In order to avoid this increased risk for the baby while preserving the obstetric advantages, alongside birth centers offer an intermediate solution. They combine the reassuring home-like atmosphere with the safety of the hospital. In Belgium, the first alongside birth center " Le Cocon " (a low technicity unit distinct from the delivery room) offers now this type of alternative place of birth for women in Hôpital Erasme in Brussels.

Full Text Available BackgroundOptimal birth spacing has health advantages for both mother and child. In developing countries, shorter birth intervals are common and associated with social, cultural and economic factors, as well as a lack of family planning. This study investigated the first birth interval after marriage and preceding interbirth interval in Nepal.MethodsA community-based prospective cohort study was conducted in the Kaski district of Nepal. Information on birth spacing, demographic and obstetric characteristics was obtained from 701 pregnant women using a structured questionnaire. Logistic regression analyses were performed to ascertain factors associated with short birth spacing.ResultsAbout 39% of primiparous women gave their first child birth within one year of marriage and 23% of multiparous women had short preceding interbirth intervals (<24 months. The average birth spacing among the multiparous group was 44.9 (SD 21.8 months. Overall, short birth spacing appeared to be inversely associated with advancing maternal age.For the multiparous group, Janajati and lower caste women, and those whose newborn was female, were more likely to have short birth spacing.ConclusionsThe preceding interbirth interval was relatively long in the Kaski district of Nepal and tended to be associated with maternal age, caste, and sex of newborn infant. Optimal birth spacing programs should target Janajati and lower caste women, along with promotion of gender equality in society.

Abnormalities in reward processing are crucial symptoms of major depressive disorder (MDD) and schizophrenia (SCH). Recent neuroscientific findings regarding MDD have led to conclusions about two different symptoms related to reward processing: motivational and consummatory anhedonia, corresponding, respectively, to impaired motivation to obtain rewards ('wanting'), and diminished satisfaction from consuming them ('liking'). One can ask: which of these is common for MDD and SCH. In our review of the latest neuroscientific studies, we show that MDD and SCH do not share consummatory anhedonia, as SCH patients usually have unaltered liking. Therefore, we investigated whether motivational anhedonia is the common symptom across MDD and SCH. With regard to the similarities and differences between the neural mechanisms of MDD and SCH, here we expand the current knowledge of motivation deficits and present the common underlying mechanism of motivational anhedonia - the dopamine dysregulation hypothesis - stating that any prolonged dysregulation in tonic dopamine signaling that exceeds the given equilibrium can lead to striatal dysfunction and motivational anhedonia. The implications for further research and treatment of MDD and SCH are also discussed.

Full Text Available Objective. Preterm birth (PTB remains a major cause of neonatal morbidity and mortality. The association between PTB and infection is clear. The purpose of this report is to present a focused review of information on the use of antibiotics to prevent PTB. Methods. We performed a search of the PubMed database restricted to clinical trials or meta-analyses published in English from 1990 through May 2011 using keywords “antibiotics or antimicrobials” and “preterm.” Results. The search yielded 67 abstracts for review. We selected 31 clinical trials (n=26 or meta-analysis (n=5 for further full-text review. Discussion of each eligible clinical trial, its specific inclusion criteria, antibiotic regimen used, and study results are presented. Overall, trials evaluating antibiotic treatment to prevent preterm birth have yielded mixed results regarding any benefit. Conclusion. Routine antibiotic prophylaxis is not recommended for prevention of preterm birth.

Maternal obesity is a major source of preventable perinatal morbidity, but studies of the relationship between obesity and preterm birth have been inconsistent. This review looks at two major studies covering just under 3.5 million births, from California, USA, and Sweden. Inconsistent findings in previous studies appear to stem from the complex relationship between obesity and preterm birth. Initiatives to decrease maternal obesity represent an important strategy in reducing preterm birth. ©2014 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

This study determined the profile and birthing practices in both modern and traditional ways among Maranao traditional birth attendants (TBAs) in Lanao del Norte, Philippines. It employed a descriptive research design. The respondents were 50 Maranao TBAs selected through the snowball sampling technique. A questionnaire was developed by the researchers to identify the respondents' modern birthing practices utilizing the Essential Intrapartum and Newborn Care (EINC) Protocol. To determine their profile and traditional birthing practices, items from a previous study and the respondents' personal claims were adapted. This study shows that Maranao TBAs have less compliance to the EINC Protocol and they often practice the traditional birthing interventions, thus increasing the risk of complications to both mother and newborn.

Full Text Available Vitamin D, besides its classical role in bone metabolism, plays a distinct role in multiple pathways of the feto-maternal unit. Calcitriol is the major active ligand of the nuclear vitamin D receptor (VDR. The vitamin D receptor (VDR is expressed in different uteroplacental parts and exerts a variety of functions in physiologic pregnancy. It regulates decidualisation and implantation, influences hormone secretion and placental immune modulations. This review highlights the role of the vitamin D receptor in physiologic and disturbed pregnancy, as preeclampsia, fetal growth restriction, gestational diabetes and preterm birth. We discuss the existing literature regarding common VDR polymorphisms in these pregnancy disorders.

The birth of a baby is a family experience. However, in the United Kingdom birth often occurs outside the family environment, in hospital. Both home and hospital births have risks and benefits, but research shows that, for most women, it is as safe to give birth at home as it is in hospital. Women report home-birth to be satisfying with lowered risks of intervention and less likelihood of being separated from their family. It is also more cost effective for the National Health Service. Yet, whilst midwives are working hard to promote home birth as an option, it remains controversial. The aim of this paper is to raise awareness of the safety of home birth and the needs of women and midwives when a home birth is chosen. It provides an overview of care required and the role of the midwife in the ensuring care is woman-centred and personalised.

Preterm birth is the most important direct cause of neonatal mortality and remains a major challenge for obstetrics and global health. Intrauterine infection causes approximately 50% of early preterm births. Animal models using pregnant mice, rabbits, or sheep, demonstrate the key link between infection and premature birth, but differ in mechanisms of parturition and placental structure from humans. The nonhuman primate (NHP) is a powerful model which emulates many features of human placentation and parturition. The contributions of the NHP model to preterm birth research are reviewed emphasizing the role of infections, and potential development of preventative and therapeutic strategies. PMID:21040390

Association of maternal CNVs in GSTT1/GSTT2 with smoking, preterm delivery, and low birth weight

Full Text Available Preterm delivery (PTD is an adverse birth outcome associated with increased infant mortality and negative lifelong health consequences. PTD may be the result of interactions between genetics and maternal/fetal environmental factors including smoking exposure (SMK. A common deletion in the GSTT1 gene was previously reported to affect birth outcomes in smokers. In this study, we dissect the associations among SMK, birth outcomes, and copy number variations (CNVs in the GSTT1/GSTT2 region.A preterm birth case-control dataset of 1937 mothers was part of the GENEVA preterm birth study, which included genome-wide genotyping used to identify CNVs. We examined the association of SMK with birth outcomes, detected CNVs within the GSTT1/GSTT2 region using PennCNV, and examined associations of the identified CNVs with preterm birth and with birth weight (BW in full term birth controls, including interactions with SMK. Finally, we tested the association of CNVs in GSTT1/GSTT2 with SMK.We confirmed the association of smoking with low BW and PTD. We identified 2 CNVs in GSTT2 (GSTT2a and GSTT2b, 1 CNV in GSTTP1 and 2 CNVs in GSTT1 (GSTT1a and GSTT1b. The GSTT2a deletion was associated with reduced BW (-284g, p=2.5E-7 in smokers, and was more common in smokers (odds ratio[OR]=1.3, p=0.036. We found that the size of the reported common deletion CNV in GSTT1 was larger than previously shown. The GSTTP1 and GSTT1b null genotypes were in high linkage disequilibrium (LD (D’=0.89 and less common in smokers (OR=0.68, p=0.019 and OR=0.73, p=0.055 respectively. These two deletions were in partial LD with GSTT2a and GSTT2b duplications. All 5 CNVs seem to be associated with increased risk of preterm birth before 35 completed weeks.CNVs in the GSTTT1/GSTT2 region appear associated with low BW and PTD outcomes, but LD complicated these CNVs in GSTT1/GSTT2. In genetic association studies of BW, multiple CNVs in this region need to be investigated instead of a single

The interaction of quantum system and its environment brings out abundant quantum phenomenons. The sudden death of quantum resources, including entanglement, quantum discord and coherence, have been studied from the perspective of quantum breaking channels (QBC). QBC of quantum resources reveal the common features of quantum resources. The definition of QBC implies the relationship between quantum resources. However, sudden death of quantum resources can also appear under some other quantum channels. We consider the dynamics of Bell-diagonal states under a stochastic dephasing noise along the z-direction, and the sudden death and sudden birth of quantum discord are investigated. Next we explain this phenomenon from the geometric structure of quantum discord. According to the above results, the states with sudden death and sudden birth can be filtered in three-parameter space. Then we provide two necessary conditions to judge which kind of noise channels can make Bell-diagonal states sudden death and sudden birth. Moreover, the relation between quantum discord and coherence indicates that the sudden death and sudden birth of quantum discord implies the sudden death and sudden birth of coherence in an optimal basis.

Previous studies have shown that over 40% of babies with Down syndrome have a major cardiac anomaly and are more likely to have other major congenital anomalies. Since 2000, many countries in Europe have introduced national antenatal screening programs for Down syndrome. This study aimed...... to determine if the introduction of these screening programs and the subsequent termination of prenatally detected pregnancies were associated with any decline in the prevalence of additional anomalies in babies born with Down syndrome. The study sample consisted of 7,044 live births and fetal deaths with Down...... syndrome registered in 28 European population-based congenital anomaly registries covering seven million births during 2000-2010. Overall, 43.6% (95% CI: 42.4-44.7%) of births with Down syndrome had a cardiac anomaly and 15.0% (14.2-15.8%) had a non-cardiac anomaly. Female babies with Down syndrome were...

The Burden of Provider-Initiated Preterm Birth and Associated Factors: Evidence from the Brazilian Multicenter Study on Preterm Birth (EMIP.

Renato T Souza

Full Text Available About 15 million children are born under 37 weeks of gestation worldwide. Prematurity is the leading cause of neonatal deaths and short/long term morbidities, entailing consequences not only for the individual, but also their family, health agencies, facilities and all community. The provider-initiated preterm birth is currently one of the most important obstetric conditions related to preterm births, particularly in middle and high income countries, thus decreasing the need for therapeutic preterm birth is essential to reduce global prematurity. Therefore detailed knowledge on the factors associated with provider-initiated preterm birth is essential for the efforts to reduce preterm birth rates and its consequences. In this current analysis we aimed to assess the proportion of provider-initiated (pi-PTB among preterm births in Brazil and identify associated factors.This is an analysis of a multicenter cross-sectional study with a nested case-control component called Brazilian Multicenter Study on Preterm Birth (EMIP. EMIP was conducted in 20 referral obstetric hospitals located in the three most populated of the five Brazilian regions. We analysed data of women with pi-PTB, defined as childbirth occurring at less than 37 weeks, medically indicated for maternal/fetal compromise or both; and women with term birth, childbirth at or after 37 weeks. Maternal, sociodemographic, obstetric, prenatal care, delivery, and postnatal characteristics were assessed as possible factors associated with pi-PTB, compared to term births. The overall prevalence of preterm births was 12.3%. Of these, approximately one-third of cases were initiated by the provider. Hypertensive disorders, placental abruption, and diabetes were the main maternal conditions leading to pi-PTB. Caesarean section was the most common mode of delivery.

The experience of being a traditional midwife: relationships with skilled birth attendants.

Science.gov (United States)

Dietsch, Elaine

2010-01-01

This article focuses on an unexpected finding of a research project which explored the experience of being a traditional midwife. The unexpected finding was that traditional midwives often perceive skilled (professional) birth attendants to be abusive of both them and the women who are transferred to hospital for emergency obstetric care. Eighty-four traditional midwives in the Western Province of Kenya were interviewed individually or in groups with a Bukusu/Kiswahili/English-speaking interpreter. Interviews were audiotaped and the English components were transcribed verbatim. Interview transcripts and observations were thematically analysed. A minority of relationships between traditional midwives and skilled birth attendants were based on mutual respect and collaborative practice. However, the majority of encounters with skilled birth attendants were perceived by the traditional midwives to be abusive for them and the women requiring emergency obstetric care. In the interests of improving health outcomes for women and their newborns, interpersonal skills, including maintaining respectful communication and relationships must be a core competency for all caregivers. Providing opportunities for reciprocal learning and strategies to enhance relationships between traditional midwives and skilled birth attendants are recommended. Current global strategies to reduce maternal and newborn mortality by increasing the number of women birthing with a skilled (professional) birth attendant in an enabling environment may be limited while the reasons for traditional midwives being the caregiver of choice for the majority of women living in areas such as Western Kenya remain unaddressed.

Giant panda genomic data provide insight into the birth-and-death process of mammalian major histocompatibility complex class II genes.

Full Text Available To gain an understanding of the genomic structure and evolutionary history of the giant panda major histocompatibility complex (MHC genes, we determined a 636,503-bp nucleotide sequence spanning the MHC class II region. Analysis revealed that the MHC class II region from this rare species contained 26 loci (17 predicted to be expressed, of which 10 are classical class II genes (1 DRA, 2 DRB, 2 DQA, 3 DQB, 1 DYB, 1 DPA, and 2 DPB and 4 are non-classical class II genes (1 DOA, 1 DOB, 1 DMA, and 1 DMB. The presence of DYB, a gene specific to ruminants, prompted a comparison of the giant panda class II sequence with those of humans, cats, dogs, cattle, pigs, and mice. The results indicated that birth and death events within the DQ and DRB-DY regions led to major lineage differences, with absence of these regions in the cat and in humans and mice respectively. The phylogenetic trees constructed using all expressed alpha and beta genes from marsupials and placental mammals showed that: (1 because marsupials carry loci corresponding to DR, DP, DO and DM genes, those subregions most likely developed before the divergence of marsupials and placental mammals, approximately 150 million years ago (MYA; (2 conversely, the DQ and DY regions must have evolved later, but before the radiation of placental mammals (100 MYA. As a result, the typical genomic structure of MHC class II genes for the giant panda is similar to that of the other placental mammals and corresponds to BTNL2 approximately DR1 approximately DQ approximately DR2 approximately DY approximately DO_box approximately DP approximately COL11A2. Over the past 100 million years, there has been birth and death of mammalian DR, DQ, DY, and DP genes, an evolutionary process that has brought about the current species-specific genomic structure of the MHC class II region. Furthermore, facing certain similar pathogens, mammals have adopted intra-subregion (DR and DQ and inter-subregion (between DQ and DP

Dimorphism in the Size and Shape of the Birth Canal Across Anthropoid Primates.

Moffett, Elizabeth A

2017-05-01

It has long been noted that the human female birth canal is well adapted to giving birth to large-brained neonates. However, several species of nonhuman primates give birth to large-headed neonates compared to the maternal birth canal. The presence of such large cephalopelvic proportions in nonhuman primates presents the question of whether dimorphism in the birth canals of these other species is related to obstetric demand, as such dimorphism is presumed to be in humans. In this study, the hypothesis that either the presence or magnitude of dimorphism in the birth canal is related to large cephalopelvic proportions among anthropoid primates is directly tested. This study shows that birth canal dimorphism is common among anthropoids regardless of cephalopelvic proportions, but taxa with large cephalopelvic proportions have a higher magnitude of dimorphism than those that give birth to relatively small-headed neonates. Furthermore, humans have exceptionally high levels of dimorphism that cannot be explained based on our large cephalopelvic proportions alone.

Birth weight centile curves are commonly used as a screening tool and to assess the position of a newborn on a given reference distribution. Birth weight of twins are known to be less than those of comparable singletons and twin-specific birth weight centile curves are recommended for use. In this study, we aim to construct gestational age specific birth weight centile curves for twins born in south India. The study was conducted at the Christian Medical College, Vellore, south India. The birth records of all consecutive pregnancies resulting in twin births between 1991 and 2005 were reviewed. Only live twin births between 24 and 42 weeks of gestation were included. Birth weight centiles for gestational age were obtained using the methodology of generalized additive models for location, scale and shape (GAMLSS). Centiles curves were obtained separately for monochorionic and dichorionic twins. Of 1530 twin pregnancies delivered during the study period (1991-2005), 1304 were included in the analysis. The median gestational age at birth was 36 weeks (1st quartile 34, 3rd quartile 38 weeks). Smoothed percentile curves for birth weight by gestational age increased progressively till 38 weeks and levels off thereafter. Compared with dichorionic twins, monochorionic twins had lower birth weight for gestational age from after 27 weeks. We provide centile values of birth weight at 24 to 42 completed weeks of gestation for twins born in south India. These charts could be used both in routine clinical assessments and epidemiological studies.

Full Text Available INTRODUCTION. The incidence of multiple births has increased in the last decade. Perinatal mortality in triplets is significantly greater than in twin and singleton births. OBJECTIVE. The objective of this study was to describe the extent of birth weight discordance among triplets and to identify its association with an increased risk of perinatal mortality. METHOD A retrospective analysis of triplet births, for the period 1993-2003, was conducted at the Gynaecological-Obstetric Clinic "Narodni Front" in Belgrade. Birth weight discordance was defined as the difference in birth weight between the largest and the smallest triplet's weight of more than 20%. RESULTS. The rate of triplets has increased by almost 75% between the first (7.7% and the last (29.6% 5-year period of the last decade. Triplets are becoming more common because of the frequent use of assisted reproductive technology as a treatment for infertility. In the period 1993-2003, there were a total of 40 triplet live births (24 weeks and greater with incidence of 0.06%. There was no clear association between maternal age, parity, method of conception, birth gestational age, and disorders complicating pregnancy with birth discordance more than 20%. Regarding birth weight groups, statistical significance occurred only in the <999 grams group for discordant and in the 2000-2499 grams group for concordant triplets. Overall, the perinatal mortality rate in the group was 10.8%, the foetal mortality rate was 1.7% (2/120, and the neonatal (0-28 days mortality rate was 9.1% (11/120. An odds ratio of 95% confidence interval shows 3 times greater risk for adverse perinatal outcome in the discordant group. However, the difference was not significant. CONCLUSION. Increasing birth weight discordance may increase the risk of adverse perinatal outcome. Triplet pregnancies, being high risk, require intensive antenatal care in order to prevent preterm delivery and ultrasound in order to diagnose foetal

Magnitude of Birth Defects in Central and Northwest Ethiopia from 2010-2014: A Descriptive Retrospective Study.

Full Text Available Birth defects are defined as structural and functional defects that develop during the organogenesis period and present at birth or detected later in life. They are one of the leading causes of infant and child mortality, morbidity, and long term disability. The magnitude of birth defects varies from country to country and from race/ethnicity to race/ethnicity, and about 40-60% of their causes are unknown. The known causes of birth defects are genetic and environmental factors which may be prevented. For various reasons, there is lack of data and research on birth defects in Ethiopia.The major objective of this study is to estimate the magnitude of birth defects in Ethiopia.A hospital based, retrospective, cross sectional, descriptive study was conducted. The subjects were babies/children aged 0-17years who visited selected hospitals between 2010 and 2014. Fourteen hospitals (8 in Addis Ababa, 6 in Amhara Region were selected purposively based on case load. A data retrieving form was developed to extract relevant information from record books.In the hospitals mentioned, 319,776 various medical records of children aged 0-17years were found. Of these, 6,076 (1.9% with 95% CI: 1.85%-1.95% children were diagnosed as having birth defects. The majority (58.5% of the children were male and 41.5% female. A slightly more than half (51.1% of the children were urban dwellers, while 48.9% were from rural areas.

Christophe Z Guilmoto

Full Text Available INTRODUCTION: Since the 1980s, sex ratio at birth (male births per 100 female births has increased in many Asian countries as a result of selective abortions, but to date there has been no such evidence for Viet Nam. Our aim in this paper is to ascertain the situation with respect to sex ratio at birth in Viet Nam over the past five years. MATERIALS AND METHODS: Original data were obtained from sample population surveys in Viet Nam recording annual birth rates since 2000 of about 450,000 women, as well as from two successive birth surveys conducted for the first time in 2007 (1.1 million births. The annual population surveys include specific information on birth history and mothers' characteristics to be used for the analysis of trends and differentials in sex ratio at birth. RESULTS AND DISCUSSION: Birth history statistics indicate that the SRB in Viet Nam has recorded a steady growth since 2001. Starting from a level probably close to the biological standard of 105, the SRB reached 108 in 2005 and 112 in 2006, a value significantly above the normal level. An independent confirmation of these results comes from the surveys of births in health facilities which yielded a SRB of 110 in 2006-07. High SRB is linked to various factors such as access to modern health care, number of prenatal visits, level of higher education and employment status, young age, province of residence and prenatal sex determination. These results suggest that prenatal sex determination followed by selective abortion has recently become more common in Viet Nam. This recent trend is a consequence of various factors such as preference for sons, declining fertility, easy access to abortion, economic development as well as the increased availability of ultrasonography facilities.

Introduction The vast majority of planned out-of-hospital births in the United States occur among white women; no study has addressed whether black women prefer out-of-hospital birth less or whether this racial disparity is due to other causes such as constrained access. This study sought to answer the question of whether white and black women feel safest giving birth in out-of-hospital settings at different rates, and whether this answer is associated with other socioeconomic indicators. Methods An interview of 634 nulliparous women during the third trimester of their pregnancy in Michigan provided data regarding where women felt safest giving birth. Feeling safest giving birth out-of-hospital was examined in relation to socioeconomic factors including race, age, household income, education, residence in a high-crime neighborhood, partnered status, and type of insurance. Results This study found that black and white women say they feel safest giving birth in out-of-hospital settings at similar rates (11.5% and 13.1% respectively). Logistic regression results showed that poverty and having education beyond high school were the only sociodemographic indicators significantly associated with feeling safest giving birth out-of-hospital. Discussion Disparities evident in planned homebirth and birth center rates cannot be explained by racial differences in feelings toward out-of-hospital birth and should be addressed more specifically in public policy and future studies.

Full Text Available Background: Proper time intervals among pregnancies has a major role in family provision. Investigating the dynamism of the birth spacing, identify factors and their effects on the time interval among pregnancies and determination of optimal spacing is the utmost importance for health planners and families. The purpose was to study the abortion and stillbirth due to short inter-birth spacing, factors affecting inter-births and optimal birth spacing. Material and Methods: In 2005, a cross-sectional study was conducted in a population of 1064 women of childbearing age in Fars province by multistage random sampling. Information on reproductive history was collected by resident health workers. Variables affecting inter-births were checked by the frailty recurrent events model using S-plus 2000 and SPSS 13 software. Results: The rate of abortion or stillbirth was 1.7%, which fell with increasing interval between births and reached their lowest (1.9% at 36-48 months. Mother's level of education, duration of breastfeeding of previous infant, maternal age at birth and father's job showed positive correlation with inter-birth. Mother's age at marriage, having a job other than household, socioeconomic status was negatively correlated with the the time interval to the next delivery. With increasing birth order, inter-birth of each delivery with regard to previous delivery increased on average by one to two months. Conclusion: The risk of abortion and stillbirth were observed more in subsequent delivery with very low or very long gap interval.

Limited systematic research on maternal placentophagy is available to maternity care providers whose clients/patients may be considering this increasingly popular practice. Our purpose was to characterize the practice of placentophagy and its attendant neonatal outcomes among a large sample of women in the United States. We used a medical records-based data set (n = 23 242) containing pregnancy, birth, and postpartum information for women who planned community births. We used logistic regression to determine demographic and clinical predictors of placentophagy. Finally, we compared neonatal outcomes (hospitalization, neonatal intensive unit admission, or neonatal death in the first 6 weeks) between placenta consumers and nonconsumers, and participants who consumed placenta raw vs cooked. Nearly one-third (31.2%) of women consumed their placenta. Consumers were more likely to have reported pregravid anxiety or depression compared with nonconsumers. Most (85.7%) placentophagic mothers consumed their placentas in encapsulated form, and nearly half (49.1%) consumed capsules containing dehydrated, uncooked placenta. Placentophagy was not associated with any adverse neonatal outcomes. Women with home births were more likely to engage in placentophagy than women with birth center births. The most common reason given (58.6%) for engaging in placentophagy was to prevent postpartum depression. The majority of women consumed their placentas in uncooked/encapsulated form and hoping to avoid postpartum depression, although no evidence currently exists to support this strategy. Preparation technique (cooked vs uncooked) did not influence adverse neonatal outcomes. Maternity care providers should discuss the range of options available to prevent/treat postpartum depression, in addition to current evidence with respect to the safety of placentophagy. © 2018 Wiley Periodicals, Inc.

Background Observational epidemiological studies indicate that maternal height is associated with gestational age at birth and fetal growth measures (i.e., shorter mothers deliver infants at earlier gestational ages with lower birth weight and birth length). Different mechanisms have been postulated to explain these associations. This study aimed to investigate the casual relationships behind the strong association of maternal height with fetal growth measures (i.e., birth length and birth weight) and gestational age by a Mendelian randomization approach. Methods and Findings We conducted a Mendelian randomization analysis using phenotype and genome-wide single nucleotide polymorphism (SNP) data of 3,485 mother/infant pairs from birth cohorts collected from three Nordic countries (Finland, Denmark, and Norway). We constructed a genetic score based on 697 SNPs known to be associated with adult height to index maternal height. To avoid confounding due to genetic sharing between mother and infant, we inferred parental transmission of the height-associated SNPs and utilized the haplotype genetic score derived from nontransmitted alleles as a valid genetic instrument for maternal height. In observational analysis, maternal height was significantly associated with birth length (p = 6.31 × 10−9), birth weight (p = 2.19 × 10−15), and gestational age (p = 1.51 × 10−7). Our parental-specific haplotype score association analysis revealed that birth length and birth weight were significantly associated with the maternal transmitted haplotype score as well as the paternal transmitted haplotype score. Their association with the maternal nontransmitted haplotype score was far less significant, indicating a major fetal genetic influence on these fetal growth measures. In contrast, gestational age was significantly associated with the nontransmitted haplotype score (p = 0.0424) and demonstrated a significant (p = 0.0234) causal effect of every 1 cm increase in maternal

To determine whether training traditional birth attendants to manage several common perinatal conditions could reduce neonatal mortality in the setting of a resource poor country with limited access to healthcare. Prospective, cluster randomised and controlled effectiveness study. Lufwanyama, an agrarian, poorly developed district located in the Copperbelt province, Zambia. All births carried out by study birth attendants occurred at mothers' homes, in rural village settings. 127 traditional birth attendants and mothers and their newborns (3559 infants delivered regardless of vital status) from Lufwanyama district. Using an unblinded design, birth attendants were cluster randomised to intervention or control groups. The intervention had two components: training in a modified version of the neonatal resuscitation protocol, and single dose amoxicillin coupled with facilitated referral of infants to a health centre. Control birth attendants continued their existing standard of care (basic obstetric skills and use of clean delivery kits). The primary outcome was the proportion of liveborn infants who died by day 28 after birth, with rate ratios statistically adjusted for clustering. Secondary outcomes were mortality at different time points; and comparison of causes of death based on verbal autopsy data. Among 3497 deliveries with reliable information, mortality at day 28 after birth was 45% lower among liveborn infants delivered by intervention birth attendants than control birth attendants (rate ratio 0.55, 95% confidence interval 0.33 to 0.90). The greatest reductions in mortality were in the first 24 hours after birth: 7.8 deaths per 1000 live births for infants delivered by intervention birth attendants compared with 19.9 per 1000 for infants delivered by control birth attendants (0.40, 0.19 to 0.83). Deaths due to birth asphyxia were reduced by 63% among infants delivered by intervention birth attendants (0.37, 0.17 to 0.81) and by 81% within the first two days

Delivery with skilled birth attendants is important for reducing maternal mortality in developing countries. However, traditional birth attendants (TBAs) are abundant in such settings, managing deliveries without the skills and resources necessary to prevent mortality in this situations. Interventions that have been proposed to mitigate the situation include redefining the role of TBAs to nutrition advocates and birth companions for pregnant women to health facilities. We thus explored community perceptions on these new roles of TBAs, as birth companions and nutrition advocates, and their influence on health facility deliveries in Kakamega County, Kenya. Qualitative data was collected through key informant interviews with health workers and focus group discussions with lactating mothers, pregnant women, husbands, community leaders, community health volunteers, and TBA. Content analysis was conducted; data was organized into subthemes and conclusions made from each subtheme using Atlas.ti software. TBAs adopted their birth companion role as the majority offered companionship to mothers delivering at health facilities. Mothers were happy with this role as TBAs continued providing companionship even after delivery. The community members were happy with the new role of TBAs and reported increased deliveries at the health facilities. In contrast, TBAs did not adopt the nutrition advocacy role sufficiently. We found that redefining the role of the TBAs into birth companions to support facility-based delivery is thus feasible and acceptable. Nutrition advocacy by the TBAs should be strengthened to maximize on the opportunity provided by the close association between TBAs and mothers and the community. © 2018 John Wiley & Sons Ltd.

Hospital births, when compared to out-of-hospital births, have generally led to not only a significantly reduced maternal and perinatal mortality and morbidity but also an increase in certain interventions. A trend seems to be emerging, especially in the US where some women are requesting home births, which creates ethical challenges for obstetricians and the health care organizations and policy makers. In the developing world, a completely different reality exists. Home births constitute the majority of deliveries in the developing world. There are severe limitations in terms of facilities, health personnel and deeply entrenched cultural and socio-economic conditions militating against hospital births. As a consequence, maternal and perinatal mortality and morbidity remain the highest, especially in Sub-Saharan Africa (SSA). Midwife-assisted planned home birth therefore has a major role to play in increasing the safety of childbirth in SSA. The objective of this paper is to propose a model that can be used to improve the safety of childbirth in low resource countries and to outline why midwife assisted planned home birth with coordination of hospitals is the preferred alternative to unassisted or inadequately assisted planned home birth in SSA.

Economic implications of home births and birth centers: a structured review.

It is widely perceived that home births and birth centers may help decrease the costs of maternity care for women with uncomplicated pregnancies and deliveries. This structured review examines the literature relating to the economic implications of home births and birth center care compared with hospital maternity care. The bibliographic databases MEDLINE (from 1950), CINAHL (from 1982), EMBASE (from 1980), and an "in-house" database, Econ2, were searched for relevant English language publications using MeSH and free text terms. Data were extracted with respect to the study design, inclusion criteria, clinical and cost results, and details of what was included in the cost calculations. Eleven studies were included from the United Kingdom, United States, Australia, and Canada. Two studies focused on home births versus other forms and locations of care, whereas nine focused on birth centers versus other forms and locations of care. Resource use was generally lower for women cared for at home and in birth centers due to lower rates of intervention, shorter lengths of stay, or both. However, this fact did not always translate into lower costs because, in the U.K. where many studies were conducted, more midwives of a higher grade were employed to manage the birth centers than are usually employed in maternity units, and because of costs of converting existing facilities into delivery rooms. The quality of much of the literature was poor, although no studies were excluded for this reason. Selection bias was likely to be a problem in those studies not based on randomized controlled trials because, even where birth center eligibility was applied throughout, women who choose to deliver at home or in a birth center are likely to be different in terms of expectations and approach from women choosing to deliver in hospital. This review highlights the paucity of economic literature relating to home births and birth centers. Differences in results between studies may be

INTRODUCTION: The aim of this study was to describe and compare contraceptive use, fertility, birth, and abortion rates in the Nordic countries. MATERIAL AND METHODS: National data on births, abortions, fertility rate (1975-2013), redeemed prescriptions of hormonal contraceptives and sales figures...... contraception followed by the levonorgestrel-releasing intrauterine system were the most common methods. During 1975-2013 abortion rates decreased in Denmark (from 27/1000 women to 15/1000 women aged 15-44/1000 women) and Finland (from 20 to 10/1000 women), remained stable in Norway (≈16) and Sweden (≈20......) and increased in Iceland (from 6 to 15/1000 women). Birth rates remained stable around 60/1000 women aged 15-44 in all countries except for Iceland where the birth rate decreased from 95 to 65/1000 women. Abortion rates were highest in the age group 20-24 years. In the same age group, Sweden had a lower...

Although most children and adults who are born very preterm live healthy lives, they have, on average, lower cognitive scores, more internalizing behaviors, and deficits in social skills. This could well affect their transition to adulthood. We studied the tempo of first leaving the parental home and starting cohabitation with an intimate partner and sexual experience of young adults with very low birth weight (Adults, 162 very low birth weight individuals and 188 individuals who were born at term (mean age: 22.3 years [range: 18.5-27.1]) and did not have any major disability filled out a questionnaire. For analysis of their ages at events which had not occurred in all subjects, we used survival analysis (Cox regression), adjusted for gender, current height, parents' ages at the birth, maternal smoking during pregnancy, parental educational attainment, number of siblings, and parental divorce/death. During their late teens and early adulthood, these very low birth weight adults were less likely to leave the parental home and to start cohabiting with an intimate partner. In gender-stratified analyses, these hazard ratios were similar between genders, but the latter was statistically significant for women only. These very low birth weight adults were also less likely to experience sexual intercourse. This relationship was statistically significant for women but not for men; however, very low birth weight women and men both reported a smaller lifetime number of sex partners than did control subjects. Healthy young adults with very low birth weight show a delay in leaving the parental home and starting sexual activity and partnerships.

Bedouin Arab women delivering newborns at Soroka Medical Center, Israel, during 1 year were interviewed in hospital to determine the factors influencing infant feeding practices at birth. Eighty-six per cent breastfed, 11% breast and bottlefed, and 3% bottlefed at birth. Based on a multiple logistic regression analysis, the factors that significantly reduced the odds ratio (OR) of exclusive breastfeeding vs. breast and bottle feeding or bottle feeding at birth include: delivering during the high birth season (OR = 0.49); maternal recall of feeling unwell during pregnancy (OR = 0.59); delivering a low birthweight newborn (OR = 0.10); a newborn diagnosed with major malformations (OR = 0.30) or with major illnesses (OR = 0.32); and delivering by Caesarean section (OR = 0.09). In contrast, multiparae experienced an increased odds (OR = 1.67) of breastfeeding. Among primiparae, the factors that significantly reduced the odds of exclusive breastfeeding include: delivering during the high birth season (OR = 0.47); delivering a low birthweight newborn (OR = 0.12); and delivering by Caesarean section (OR = 0.18). Mothers of high-risk neonates and those who deliver by Caesarean section need to be educated about the benefits of exclusive breastfeeding. Young primiparae are a challenge and require qualitative and quantitative research into the reasons precluding exclusive breastfeeding.

Pesticides exposures are aspects of the human exposome that have not been sufficiently studied for their contribution to risk for preterm birth. We investigated risks of spontaneous preterm birth from potential residential exposures to 543 individual chemicals and 69 physicochemical groupings that were applied in the San Joaquin Valley of California during the study period, 1998-2011. The study population was derived from birth certificate data linked with Office of Statewide Health Planning and Development maternal and infant hospital discharge data. After exclusions, the analytic study base included 197,461 term control births and 27,913 preterm case births. Preterm cases were more narrowly defined as 20-23 weeks (n = 515), 24-27 weeks (n = 1,792), 28-31 weeks (n = 3,098), or 32-36 weeks (n = 22,508). The frequency of any (versus none) pesticide exposure was uniformly lower in each preterm case group relative to the frequency in term controls, irrespective of gestational month of exposure. All odds ratios were below 1.0 for these any versus no exposure comparisons. The majority of odds ratios were below 1.0, many of them statistically precise, for preterm birth and exposures to specific chemical groups or chemicals. This study showed a general lack of increased risk of preterm birth associated with a range of agriculture pesticide exposures near women's residences.

Women who seek vaginal birth after cesarean delivery may find limited in-hospital options. Increasing numbers of women in the United States are delivering by vaginal birth after cesarean delivery out-of-hospital. Little is known about neonatal outcomes among those who deliver by vaginal birth after cesarean delivery in- vs out-of-hospital. The purpose of this study was to compare neonatal outcomes between women who deliver via vaginal birth after cesarean delivery in-hospital vs out-of-hospital (home and freestanding birth center). We conducted a retrospective cohort study using 2007-2010 linked United States birth and death records to compare singleton, term, vertex, nonanomolous, and liveborn neonates who delivered by vaginal birth after cesarean delivery in- or out-of-hospital. Descriptive statistics and multivariate regression analyses were conducted to estimate unadjusted, absolute, and relative birth-setting risk differences. Analyses were stratified by parity and history of vaginal birth. Sensitivity analyses that involved 3 transfer status scenarios were conducted. Of women in the United States with a history of cesarean delivery (n=1,138,813), only a small proportion delivered by vaginal birth after cesarean delivery with the subsequent pregnancy (n=109,970; 9.65%). The proportion of home vaginal birth after cesarean delivery births increased from 1.78-2.45%. A pattern of increased neonatal morbidity was noted in unadjusted analysis (neonatal seizures, Apgar score birthing their second child by vaginal birth after cesarean delivery in out-of-hospital settings had higher odds of neonatal morbidity and death compared with women of higher parity. Women who had not birthed vaginally prior to out-of-hospital vaginal birth after cesarean delivery had higher odds of neonatal morbidity and mortality compared with women who had birthed vaginally prior to out-of-hospital vaginal birth after cesarean delivery. Sensitivity analyses generated distributions of plausible

Giving birth with rape in one's past: a qualitative study.

Rape is one of the most traumatizing violations a woman can be subjected to, and leads to extensive health problems, predominantly psychological ones. A large proportion of women develop a form of posttraumatic stress termed Rape Trauma Syndrome. A previous study by our research group has shown that women with a history of rape far more often had an operative delivery in their first birth and those who gave birth vaginally had second stages twice as long as women with no history of sexual assault. The aim of this study is to examine and illuminate how women previously subjected to rape experience giving birth for the first time and their advice on the kind of birth care they regard as good for women with a history of rape. A semi-structured interview with 10 women, who had been exposed to rape before their first childbirth. Data on the birth experience were analyzed by qualitative content analysis. The main theme was "being back in the rape" with two categories: "reactivation of the rape during labor," with subcategories "struggle," "surrender," and "escape" and "re-traumatization after birth," with the subcategories "objectified," "dirtied," and "alienated body." A rape trauma can be reactivated during the first childbirth regardless of mode of delivery. After birth, the women found themselves re-traumatized with the feeling of being dirtied, alienated, and reduced to just a body that another body is to come out of. Birth attendants should acknowledge that the common measures and procedures used during normal birth or cesarean section can contribute to a reactivation of the rape trauma. © 2013, Copyright the Authors Journal compilation © 2013, Wiley Periodicals, Inc.

Planned and unplanned home births and hospital births in Calgary, Alberta, 1984-87.

Science.gov (United States)

Abernathy, T J; Lentjes, D M

1989-01-01

Information collected on all home births in Calgary (Canada) between the years 1984 and 1987, was examined and analyzed according to whether the home birth environment had been planned or unplanned. The two groups were compared to each other and to all hospital births according to demographic characteristics of mothers, indicators of prenatal care, and birth outcome. Mothers who had planned their home birth were more likely to be primiparous, attend prenatal classes, obtain regular prenatal care from a physician, and have babies with a higher birth weight than either the unplanned or hospital group. Of particular concern, however, were the subset of unplanned home births who were primiparous. These mothers attended prenatal classes less frequently than any other group, reported the lowest number of physician visits, were youngest, and least likely to be married. In addition their babies averaged the shortest gestational age and the lowest birth weight. Findings in general show that planned and unplanned home births must be considered as heterogeneous groups in any comparison of risk factors and of birth outcome between home and hospital births. Further, within the unplanned group, multiparous women differ from primiparous women. Given the limitations inherent in this and similar studies, the apparent better outcome in the planned home birth group, as measured by birth weight, must be viewed with caution.

While most often transient, brachial plexus birth injury can cause permanent neurologic injury. The major risk factors for brachial plexus birth injury are fetal macrosomia and shoulder dystocia. The degree of injury to the brachial plexus should be determined in the neonatal nursery, as those infants with the most severe injury--root avulsion--should be referred early for surgical evaluation so that microsurgical repair of the plexus can occur by 3 months of life. Microsurgical repair options include nerve grafts and nerve transfers. All children with brachial plexus birth injury require ongoing physical and occupational therapy and close follow-up to monitor progress.

Amirian, E; Scheurer, Michael E; Bondy, Melissa L

2010-06-01

The etiology of brain tumors is still largely unknown. Previous research indicates that infectious agents and immunological characteristics may influence adult glioma risk. The purpose of our study was to evaluate the effects of birth order and sibship size (total number of siblings), as indicators of the timing and frequency of early life infections, on adult glioma risk using a population of 489 cases and 540 cancer-free controls from the Harris County Brain Tumor Study. Odds ratios for birth order and sibship size were calculated separately from multivariable logistic regression models, adjusting for sex, family history of cancer, education, and age. Each one-unit increase in birth order confers a 13% decreased risk of glioma development in adulthood (OR = 0.87, 95% CI = 0.79-0.97). However, sibship size was not significantly associated with adult glioma status (OR = 0.97, 95% CI = 0.91-1.04). Our study indicates that individuals who were more likely to develop common childhood infections at an earlier age (those with a higher birth order) may be more protected against developing glioma in adulthood. More biological and epidemiological research is warranted to clarify the exact mechanisms through which the timing of common childhood infections and the course of early life immune development affect gliomagenesis.

Preterm birth is the most significant problem in current obstetric practice and according to WHO is the direct cause accounting for 24% of neonatal deaths. Objective: To assess frequency and neonatal outcome in patients with preterm birth. Methodology: A prospective descriptive study was conducted at Gynae Unit III Jinnah Hospital Lahore over a period of one year (from 1st July 2011 to 30th June included in the study. For data collection two groups were made depending upon duration of pregnancy. Group l was allotted to women who were pregnant 2012) in collaboration with Paediatrics department. All labouring women who presented after 28 weeks and before 37 completed weeks of gestation were less ( ) than 32 weeks of gestation. Data was collected and analyzed by SPSS version 16. Results: During the study period total 5171 deliveries took place. Out of 5171 neonates born, 460 were preterm making the frequency of 8.86%. Majority 62.82% were > 32 weeks of gestation, 67.39% were male, 57.60% were > 1.5 kg by weight, 57.17% delivered vaginally and 80.86% were born alive. Neonatal morbidity was more common in neonates less than 32 weeks of gestation. Perinatal mortality was 10.48% in this study. Conclusion: Neonatal morbidity and mortality is more common in neonates less than 32 weeks of gestation, this can be improved by improving prenatal health services and advanced neonatal care.

Weinberg, Clarice R; Shi, Min; DeRoo, Lisa A; Basso, Olga; Skjærven, Rolv

2015-06-01

Preterm birth is a common, costly and dangerous pregnancy complication. Seasonality of risk would suggest modifiable causes. We examine seasonal effects on preterm birth, using data from the Medical Birth Registry of Norway (2,321,652 births), and show that results based on births are misleading and a fetuses-at-risk approach is essential. In our harmonic-regression Cox proportional hazards model we consider fetal risk of birth between 22 and 37 completed weeks of gestation. We examine effects of both day of year of conception (for early effects) and day of ongoing gestation (for seasonal effects on labour onset) as modifiers of gestational-age-based risk. Naïve analysis of preterm rates across days of birth shows compelling evidence for seasonality (P distribution of the fetal population at risk. When we instead properly treat fetuses as the individuals at risk, restrict analysis to pregnancies with relatively accurate ultrasound-based assessment of gestational age (available since 1998) and adjust for socio-demographic factors and maternal smoking, we find modest effects of both time of year of conception and time of year at risk, with peaks for early preterm near early January and early July. Analyses of seasonal effects on preterm birth are demonstrably vulnerable to confounding by seasonality of conception, measurement error in conception dating, and socio-demographic factors. The seasonal variation based on fetuses reveals two peaks for early preterm, coinciding with New Year's Day and the early July beginning of Norway's summer break, and may simply reflect a holiday-related pattern of unintended conception.

Catling, C; Petrovska, K; Watts, N; Bisits, A; Homer, C S E

2016-04-01

Since the Term Breech Trial in 2000, few Australian clinicians have been able to maintain their skills to facilitate vaginal breech births. The overwhelming majority of women with a breech presentation have been given one birth option, that is, caesarean section. The aim of this study was to explore clinician's experiences of caring for women when facilitating a vaginal breech birth. A descriptive exploratory design was undertaken. Nine clinicians (obstetricians and midwives) from two tertiary hospitals in Australia who regularly facilitate vaginal breech birth were interviewed. The interviews were analysed thematically. Participants were five obstetricians and four midwives. There were two overarching themes that arose from the data: Facilitation of and Barriers to vaginal breech birth. A number of sub-themes are described in the paper. In order to facilitate vaginal breech birth and ensure it is given as an option to women, it is necessary to educate, upskill and support colleagues to increase their confidence and abilities, carefully counsel and select suitable women, and approach the option in a calm, collaborative way.

To determine the effects of infants' birth order, maternal age, and socioeconomic status (SES) on birth weight. This cross-sectional study included a sample of 858 mothers recruited over a 6-month period in 2010, in a defined population of 9 urban health centers, and who were admitted for their infants' first vaccination. Maternal clinical data, demographic data, and infants' birth weight were obtained from the interview and maternal hospital files. Multiple regression and analysis of variance were used for data analysis. First and fourth births had lower birth weights compared with second and third births in all maternal ages in controlling parity, birth weight increases with maternal age up to the early 24, and then tends to level off. Male gender, maternal age 20-24 years, second and third births had a significant positive effect on birth weight. Lower family economic status and higher educational attainment were significantly associated with lower birth weight. For women in the 15-19 and 40-44 years age groups, the second birth order was associated with the most undesirable effect on birth weight. Accessibility of health care services, parity, maternal age, and socioeconomic factors are strongly associated with infants' birth weight.

Midwives frequently witness traumatic birth events. Little is known about responses to birth trauma and prevalence of posttraumatic stress among Australian midwives. To assess exposure to different types of birth trauma, peritraumatic reactions and prevalence of posttraumatic stress. Members of the Australian College of Midwives completed an online survey. A standardised measure assessed posttraumatic stress symptoms. More than two-thirds of midwives (67.2%) reported having witnessed a traumatic birth event that included interpersonal care-related trauma features. Midwives recalled strong emotions during or shortly after witnessing the traumatic birth event, such as feelings of horror (74.8%) and guilt (65.3%) about what happened to the woman. Midwives who witnessed birth trauma that included care-related features were significantly more likely to recall peritraumatic distress including feelings of horror (OR=3.89, 95% CI [2.71, 5.59]) and guilt (OR=1.90, 95% CI [1.36, 2.65]) than midwives who witnessed non-interpersonal birth trauma. 17% of midwives met criteria for probable posttraumatic stress disorder (95% CI [14.2, 20.0]). Witnessing abusive care was associated with more severe posttraumatic stress than other types of trauma. Witnessing care-related birth trauma was common. Midwives experience strong emotional reactions in response to witnessing birth trauma, in particular, care-related birth trauma. Almost one-fifth of midwives met criteria for probable posttraumatic stress disorder. Midwives carry a high psychological burden related to witnessing birth trauma. Posttraumatic stress should be acknowledged as an occupational stress for midwives. The incidence of traumatic birth events experienced by women and witnessed by midwives needs to be reduced.

2016-06-01

Planned home birth is a paradigmatic case study of the importance of ethics and professionalism in contemporary perinatology. In this article we provide a summary of recent analyses of the Centers for Disease Control database on attendants and birth outcomes in the United States. This summary documents the increased risks of neonatal mortality and morbidity of planned home birth as well as bias in Apgar scoring. We then describe the professional responsibility model of obstetric ethics, which is based on the professional medical ethics of two major figures in the history of medical ethics, Drs. John Gregory of Scotland and Thomas Percival of England. This model emphasizes the identification and careful balancing of the perinatologist's ethical obligations to pregnant, fetal, and neonatal patients. This model stands in sharp contrast to one-dimensional maternal-rights-based reductionist model of obstetric ethics, which is based solely on the pregnant woman's rights. We then identify the implications of the professional responsibility model for the perinatologist's role in directive counseling of women who express an interest in or ask about planned home birth. Perinatologists should explain the evidence of the increased, preventable perinatal risks of planned home birth, recommend against it, and recommend planned hospital birth. Perinatologists have the professional responsibility to create and sustain a strong culture of safety committed to a home-birth-like experience in the hospital. By routinely fulfilling these professional responsibilities perinatologists can help to prevent the documented, increased risks planned home birth. Copyright © 2016 Elsevier Inc.

Full Text Available The study aimed to describe the experiences of a group of nurse-midwives from the city of Campinas, SP, Brasil, regarding the transition process from attending institutionalized births to attending home births, in the period 2011 – 2013. The study is of the experience report type; the reflections, perceptions and challenges experienced in this process were collected using the technique of brainstorming. Content analysis, as proposed by Bardin, was used, which yielded four thematic categories: a the hospital experience; b living with obstetric violence; c returning home and d the challenges of home care. It is concluded that attending home births offers greater satisfaction to the nurses, even in the face of various obstacles, as it is possible to offer a care to the woman and new-born which covers both the concept of comprehensiveness and the current scientific recommendations.

A multilevel approach to the relationship between birth order and intelligence.

Wichman, Aaron L; Rodgers, Joseph Lee; MacCallum, Robert C

2006-01-01

Many studies show relationships between birth order and intelligence but use cross-sectional designs or manifest other threats to internal validity. Multilevel analyses with a control variable show that when these threats are removed, two major results emerge: (a) birth order has no significant influence on children's intelligence and (b) earlier reported birth order effects on intelligence are attributable to factors that vary between, not within, families. Analyses on 7- to 8 - and 13- to 14-year-old children from the National Longitudinal Survey of Youth support these conclusions. When hierarchical data structures, age variance of children, and within-family versus between-family variance sources are taken into account, previous research is seen in a new light.

Histological type and grade of breast cancer tumors by parity, age at birth, and time since birth: a register-based study in Norway

2010-01-01

Some studies have indicated that reproductive factors affect the risk of histological types of breast cancer differently. The long-term protective effect of a childbirth is preceded by a short-term adverse effect. Few studies have examined whether tumors diagnosed shortly after birth have specific histological characteristics. In the present register-based study, comprising information for 22,867 Norwegian breast cancer cases (20-74 years), we examined whether histological type (9 categories) and grade of tumor (2 combined categories) differed by parity or age at first birth. Associations with time since birth were evaluated among 9709 women diagnosed before age 50 years. Chi-square tests were applied for comparing proportions, whereas odds ratios (each histological type vs. ductal, or grade 3-4 vs. grade 1-2) were estimated in polytomous and binary logistic regression analyses. Ductal tumors, the most common histological type, accounted for 81.4% of all cases, followed by lobular tumors (6.3%) and unspecified carcinomas (5.5%). Other subtypes accounted for 0.4%-1.5% of the cases each. For all histological types, the proportions differed significantly by age at diagnoses. The proportion of mucinous and tubular tumors decreased with increasing parity, whereas Paget disease and medullary tumors were most common in women of high parity. An increasing trend with increasing age at first birth was most pronounced for lobular tumors and unspecified carcinomas; an association in the opposite direction was seen in relation to medullary and tubular tumors. In age-adjusted analyses, only the proportions of unspecified carcinomas and lobular tumors decreased significantly with increasing time since first and last birth. However, ductal tumors, and malignant sarcomas, mainly phyllodes tumors, seemed to occur at higher frequency in women diagnosed <2 years after first childbirth. The proportions of medullary tumors and Paget disease were particularly high among women diagnosed 2

Objective To determine whether training traditional birth attendants to manage several common perinatal conditions could reduce neonatal mortality in the setting of a resource poor country with limited access to healthcare. Design Prospective, cluster randomised and controlled effectiveness study. Setting Lufwanyama, an agrarian, poorly developed district located in the Copperbelt province, Zambia. All births carried out by study birth attendants occurred at mothers’ homes, in rural village settings. Participants 127 traditional birth attendants and mothers and their newborns (3559 infants delivered regardless of vital status) from Lufwanyama district. Interventions Using an unblinded design, birth attendants were cluster randomised to intervention or control groups. The intervention had two components: training in a modified version of the neonatal resuscitation protocol, and single dose amoxicillin coupled with facilitated referral of infants to a health centre. Control birth attendants continued their existing standard of care (basic obstetric skills and use of clean delivery kits). Main outcome measures The primary outcome was the proportion of liveborn infants who died by day 28 after birth, with rate ratios statistically adjusted for clustering. Secondary outcomes were mortality at different time points; and comparison of causes of death based on verbal autopsy data. Results Among 3497 deliveries with reliable information, mortality at day 28 after birth was 45% lower among liveborn infants delivered by intervention birth attendants than control birth attendants (rate ratio 0.55, 95% confidence interval 0.33 to 0.90). The greatest reductions in mortality were in the first 24 hours after birth: 7.8 deaths per 1000 live births for infants delivered by intervention birth attendants compared with 19.9 per 1000 for infants delivered by control birth attendants (0.40, 0.19 to 0.83). Deaths due to birth asphyxia were reduced by 63% among infants delivered by

Between 1972 and 1993 the number of hospitals and maternity homes providing obstetric help in Norway fell from 158 to 67. Most of the decline is explained by the closing down of maternity homes and obstetrical units in small hospitals, partly due to a reduction in number of births and partly to a deliberate drive towards giving birth in larger units. 16 of the 19 counties of Norway contained four or fewer obstetric institutions in 1993. Nevertheless, most of the 60,000 births took place in institutions with between 500 and 2,999 births annually. Births at home accounted for 0.3%, and births during transport for 0.2% of the total in 1990 and 1993.

Labor Dystocia: A Common Approach to Diagnosis.

Neal, Jeremy L; Lowe, Nancy K; Schorn, Mavis N; Holley, Sharon L; Ryan, Sharon L; Buxton, Margaret; Wilson-Liverman, Angela M

2015-01-01

Contemporary labor and birth population norms should be the basis for evaluating labor progression and determining slow progress that may benefit from intervention. The aim of this article is to present guidelines for a common, evidence-based approach for determination of active labor onset and diagnosis of labor dystocia based on a synthesis of existing professional guidelines and relevant contemporary publications. A 3-point approach for diagnosing active labor onset and classifying labor dystocia-related labor aberrations into well-defined, mutually exclusive categories that can be used clinically and validated by researchers is proposed. The approach comprises identification of 1) an objective point that strictly defines active labor onset (point of active labor determination); 2) an objective point that identifies when labor progress becomes atypical, beyond which interventions aimed at correcting labor dystocia may be justified (point of protraction diagnosis); and 3) an objective point that identifies when interventions aimed at correcting labor dystocia, if used, can first be determined to be unsuccessful, beyond which assisted vaginal or cesarean birth may be justified (earliest point of arrest diagnosis). Widespread adoption of a common approach for diagnosing labor dystocia will facilitate consistent evaluation of labor progress, improve communications between clinicians and laboring women, indicate when intervention aimed at speeding labor progress or facilitating birth may be appropriate, and allow for more efficient translation of safe and effective management strategies into clinical practice. Correct application of the diagnosis of labor dystocia may lead to a decrease in the rate of cesarean birth, decreased health care costs, and improved health of childbearing women and neonates. © 2015 by the American College of Nurse-Midwives.

The aims of this study were to determine the prevalence of congenital lower-limb reduction defects and associated mortality, to evaluate lower-limb deficiencies by type of reduction, and to identify patterns of associated anomalies. We conducted a population-based study with use of data from the Finnish Register of Congenital Malformations and Care Register for Health Care. All cases of lower-limb deficiency among live births, stillbirths, spontaneous abortions, and terminations of pregnancy due to fetal anomalies from 1993 to 2008 were included. We analyzed medical records and classified lower-limb reduction defects. Associated major anomalies were recorded, and perinatal mortality and infant mortality were calculated. Two hundred and sixty-six cases with lower-limb deficiency were identified, with a total prevalence of 2.8 per 10,000 births, a birth prevalence of 2.2 per 10,000 births, and a live-birth prevalence of 2.1 per 10,000 live births. Terminal transverse limb reductions accounted for 44.7% of the cases; longitudinal reductions, 22.9%; intercalary reductions, 7.9%; multiple reductions, 8.3%; and split-foot malformations, 4.5%. In addition to lower-limb deficiency, 47.7% of the cases had other major anomalies; anomalies of internal organs were noted in 26.3% of the cases, anomalies of the axial skeleton in 13.5% of cases, and central nervous system anomalies in 12.8%. Upper-limb reductions were observed in 32.0% of the cases. The relative risk (RR) for associated major anomalies was 12.54 (95% confidence interval [CI], 11.06 to 14.23) compared with the general figures for major congenital anomalies in Finland. The RR for associated anomalies was higher (1.75; 95% CI, 1.20 to 2.53) for longitudinal preaxial lower-limb deficiencies than for the other types of lower-limb reductions. Perinatal mortality was seventy-eight per 1000 births. All infant deaths were associated with chromosomal abnormalities, other known syndromes, or additional congenital

Reducing radiation exposure in newborns with birth head trauma

Full Text Available Background. Birth head trauma causing intracranial injury is one of the most common causes of neonatal mortality and morbidity. In case of suspected cranial fractures and intracranial hematomas, diagnostic methods involving radiation, such as x-ray radiography and computed tomography, are recommended. Recently, an increasing number of studies have highlighted the risk of cancer complications associated with computed tomography in infants. Therefore, diagnostic methods that reduce radiation exposure in neonates are important. One such method is ultrasonography (US. Aim. We evaluated US as a non-ionizing radiation method for diagnosis of cranial bone fractures and epidural hematomas in newborns with cephalohematomas or other birth head traumas. Material and methods. The study group included 449 newborns with the most common variant of birth head trauma: cephalohematomas. All newborns underwent transcranial-transfontanelle US for detection of intracranial changes and cranial US for visualization of bone structure in the cephalohematoma region. Children with ultrasonic signs of cranial fractures and epidural hematomas were further examined at a children’s hospital by x-ray radiography and/or computed tomography. Results and discussion. We found that cranial US for diagnosis of cranial fractures and transcranial-transfontanelle US for diagnosis of epidural hematomas in newborns were highly effective. In newborns with parietal cephalohematomas (444 children, 17 (3.8% had US signs of linear fracture of the parietal bone, and 5 (1.1% had signs of ipsilateral epidural hematoma. Epidural hematomas were visualized only when US was performed through the temporal bone and not by using the transfontanelle approach. Sixteen cases of linear fractures and all epidural hematomas were confirmed by computed tomography. Conclusion. The use of US diagnostic methods reduced radiation exposure in newborns with birth head trauma. US methods (transcranial

Urinary tract infection during pregnancy: current concepts on a common multifaceted problem.

Urinary tract infections (UTIs) are the most common bacterial infection in pregnancy, increasing the risk of maternal and neonatal morbidity and mortality. Urinary tract infections may present as asymptomatic bacteriuria, acute cystitis or pyelonephritis. Escherichia coli is the most common pathogen associated with both symptomatic and asymptomatic bacteriuria. If asymptomatic bacteriuria is untreated, up to 30% of mothers develop acute pyelonephritis, with an increased risk of multiple maternal and neonatal complications, such as preeclampsia, preterm birth, intrauterine growth restriction and low birth weight. Urinary tract infection is a common, but preventable cause of pregnancy complications, thus urinary tests, such as urine culture or new technologies such as high-throughput DNA sequence-based analyses, should be used in order to improve antenatal screening of pregnant women.

This study aims to describe the impact of twin birth, chorionicity, intertwin birth weight (BW) discordance and birth order on neonatal outcomes. We performed a hospital-based retrospective study on 2,170 twins (6.4% of all live births) and 2,217 singletons inborn 2007 to 2011. Data on neonatal characteristics, morbidities, and mortality were collected and compared. Univariate and multiple (adjusted for gestational age [GA] and gender) linear random intercept regression models were used. Overall, 62.3% of twins were born premature. At multiple regression, twins were similar to singletons for neonatal morbidities, but they were more likely to have lower BW and to be born by cesarean delivery. Monochorionic twins had lower GA and BW compared with dichorionic ones and were more likely to develop respiratory distress syndrome (odds ratio [OR], 1.7), hypoglycemia (OR, 3.3), need for transfusion, (OR, 3.4) but not brain abnormalities. Moderate and severe BW discordance were associated with longer length of stay and increased risk for morbidities but not for death. Birth order had no effects. Prematurity was the most common outcome in twins and accounted for the apparently increased risk in morbidities. Monochorionicity was confirmed as risk factor for lower GA and neonatal morbidities. BW discordance may play a role in developing neonatal complications and needs to be further investigated. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

In age-adjusted analyses, only the proportions of unspecified carcinomas and lobular tumors decreased significantly with increasing time since first and last birth. However, ductal tumors, and malignant sarcomas, mainly phyllodes tumors, seemed to occur at higher frequency in women diagnosed Conclusion Our results support previous observations that reproductive factors

This report presents preliminary data for 2005 on births in the United States. U.S. data on births are shown by age, live-birth order, race, and Hispanic origin of mother. Data on marital status, cesarean delivery, preterm births, and low birthweight (LBW) are also presented. Data in this report are based on 99.2 percent of births for 2005. The records are weighted to independent control counts of all births received in state vital statistics offices in 2005. Comparisons are made with 2004 data. The crude birth rate in 2005 was 14.0 births per 1,000 total population, unchanged from 2004. The general fertility rate, however, rose to 66.7 births per 1,000 women aged 15-44 years in 2005, the highest level since 1993. The birth rate for teenagers declined by 2 percent in 2005, falling to 40.4 births per 1,000 women aged 15-19 years, the lowest ever recorded in the 65 years for which a consistent series of rates are available. The rate declined for teenagers 15-17 years to 21.4 births per 1,000, but was essentially stable for older teenagers 18-19 years. The birth rate for women aged 20-24 years rose in 2005, whereas the rate for women aged 25-29 years was essentially unchanged. The birth rates for women aged 30 years and over rose to levels not seen in almost 40 years. Childbearing by unmarried women increased to record levels for the Nation in 2005. The birth rate rose 3 percent to 47.6 births per 1,000 unmarried women aged 15-44 years; the proportion of all births to unmarried women increased to 36.8 percent. The cesarean delivery rate rose by 4 percent in 2005 to 30.2 percent of all births, another record high for the Nation. The preterm birth rate continued to rise (to 12.7 percent in 2005) as did the rate for LBW births (8.2 percent).

Increasing incidence of testicular cancer--birth cohort effects.

The incidence of testicular cancer is rising in most Western populations. A collaborative study between nine population-based cancer registries in countries around the Baltic Sea was utilized in order to analyze in detail geographic variations and temporal trends in the occurrence of testicular cancer. There were 34,309 cases registered up until 1989 starting in Denmark in 1942 and most recently in Latvia in 1977. From the descriptive epidemiology it was obvious that there was a substantial variation in the age-standardized incidence amounting to about a 10-fold difference between the different countries ranging from 0.8 per 100,000 person-years in Lithuania to 7.6 per 100,000 person-years in Denmark. Previous studies have indicated that this increase is due to birth cohort effects. A more detailed analysis was therefore performed in those six countries with a sufficiently long period of cancer registration; Poland, former East Germany, Norway, Finland, Denmark and Sweden. This analysis showed that birth cohort is a more important determinant of testicular cancer risk than year of diagnosis. In Poland, former East Germany and Finland, there was an increasing risk for all birth cohorts. Among men born in Denmark, Norway or Sweden between 1930 and 1945, this increasing trend in risk was interrupted in these birth cohorts but followed thereafter by an uninterrupted increase by birth cohort. In conclusion, life time exposure to environmental factors which are associated with the incidence of testicular cancer appear to be more related to birth cohort than to year of diagnosis. Because testicular cancer typically occurs at an early age, major etiological factors therefore need to operate early in life, perhaps even in utero.

We conducted a field study to test whether the common ingroup identity model (Gaertner & Dovidio, 2000, reducing intergroup bias: The common ingroup identity model. Philadelphia, PA: Psychology Press) could be a useful tool to improve intergroup relations in the aftermath of a natural disaster. Participants were majority (Italian) and minority (immigrant) elementary school children (N = 517) living in the area struck by powerful earthquakes in May 2012. Results revealed that, among majority children, the perceived external threat represented by the earthquake was associated with greater perceptions of belonging to a common ingroup including both ingroup and outgroup. In turn, heightened one-group perceptions were associated with greater willingness to meet and help outgroup victims, both directly and indirectly via more positive outgroup attitudes. Among immigrant children, perceived disaster threat was not associated with any of the dependent variables; one-group perceptions were positively associated with outgroup attitudes, helping and contact intentions towards outgroup victims. Thus, one-group perceptions after a natural disaster may promote more positive and supporting relations between the majority and the minority group. We discuss the theoretical and practical implications of the findings. © 2014 The British Psychological Society.

To test the hypothesis that sleep disorder diagnosis would be associated with increased risk of preterm birth and to examine risk by gestational age, preterm birth type, and specific sleep disorder (insomnia, sleep apnea, movement disorder, and other). In this observational study, participants were from a cohort of nearly 3 million women in California between 2007 and 2012. Inclusion criteria were women with singleton neonates liveborn between 20 and 44 weeks of gestation without chromosomal abnormalities or major structural birth defects linked to a hospital discharge database maintained by the California Office of Statewide Health Planning and Development and without mental illness during pregnancy. Sleep disorder was defined based on International Classification of Diseases, 9th Revision, Clinical Modification diagnostic code (n=2,265). Propensity score matching was used to select a referent population at a one-to-one ratio. Odds of preterm birth were examined by gestational age (less than 34 weeks, 34-36 weeks, and less than 37 weeks of gestation) and type (spontaneous, indicated). Prevalence of preterm birth (before 37 weeks of gestation) was 10.9% in the referent group compared with 14.6% among women with a recorded sleep disorder diagnosis. Compared with the referent group, odds (95% CI, P value, percentage) of preterm birth were 1.3 (1.0-1.7, P=.023, 14.1%) for insomnia and 1.5 (1.2-1.8, P<.001, 15.5%) for sleep apnea. Risk varied by gestational age and preterm birth type. Odds of preterm birth were not significantly increased for sleep-related movement disorders or other sleep disorders. Insomnia and sleep apnea were associated with significantly increased risk of preterm birth. Considering the high prevalence of sleep disorders during pregnancy and availability of evidence-based nonpharmacologic interventions, current findings suggest that screening for severe presentations would be prudent.

Previous research suggested that separation anxiety disorder (SAD) is overrepresented among birth-assigned male children clinic-referred for gender dysphoria (GD). The present study examined maternally reported separation anxiety of birth-assigned male children assessed in a specialty gender identity service (N = 360). SAD was determined in relation to DSM-III and DSM-IV criteria, respectively. A dimensional metric of separation anxiety was examined in relation to several additional factors: age, ethnicity, parental marital status and social class, IQ, gender nonconformity, behavioral and emotional problems, and poor peer relations. When defined in a liberal fashion, 55.8% were classified as having SAD. When using a more conservative criterion, 5.3% were classified as having SAD, which was significantly greater than the estimated general population prevalence for boys, but not for girls. Dimensionally, separation anxiety was associated with having parents who were not married or cohabitating as well as with elevations in gender nonconformity; however, the association with gender nonconformity was no longer significant when statistically controlling for internalizing problems. Thus, SAD appears to be common among birth-assigned males clinic-referred for GD when defined in a liberal fashion, and more common than in boys, but not girls, from the general population even when more stringent criteria were applied. Also, the degree of separation anxiety appears to be linked to generic risk factors (i.e., parental marital status, internalizing problems). As such, although separation anxiety is common among birth-assigned male children clinic-referred for GD, it seems unlikely to hold unique significance for this population based on the current data.

Preterm birth is one of the leading causes of infant morbidity and mortality. Although major strides have been made in identifying risk factors for preterm birth, the complexities between social and individual risk factors are not well understood. This study examines the association between neighborhood youth violence and preterm birth. A 10-year live birth registry data set (2004 through 2013) from Richmond, VA, a mid-sized, racially diverse city, was analyzed (N = 27,519). Data were geocoded and merged with census tract and police report data. Gestational age at birth was classified as rates were calculated for each census tract area and categorized into quartiles. Hierarchical models were examined fitting multilevel logistic regression models incorporating randomly distributed census tract-specific intercepts assuming a binary distribution and a logit link function. Nearly a fifth of all births occurred in areas with the highest quartiles of violence. After adjusting for maternal age, race/ethnicity, education, paternal presence, parity, adequacy of prenatal care, pregnancy complications, history of preterm birth, insurance, and tobacco, alcohol, and drug use, census tracts with the highest level of violence had 38% higher odds of very preterm births (adjusted odds ratio, 1.38; 95% confidence interval, 1.06-1.80), than census tracts with the lowest level of violence. There is an association between high rate of youth violence and very preterm birth. Findings from this study may help inform future research to develop targeted interventions aimed at reducing community violence and very preterm birth in vulnerable populations.

To examine the change in breastfeeding behaviors over time, among low birth weight (LBW), very low birth weight (VLBW), and normal birth weight (NBW) infants using nationally representative US data. Univariate statistics and bivariate logistic models were examined using the Early Child Longitudinal Study-Birth Cohort (2001) and National Study of Children's Health (2007 and 2011/2012). Breastfeeding behaviors improved for infants of all birth weights from 2007 to 2011/2012. In 2011/2012, a higher percentage of VLBW infants were ever breastfed compared with LBW and NBW infants. In 2011/2012, LBW infants had a 28% lower odds (95% CI, 0.57-0.92) of ever breastfeeding and a 52% lower odds (95% CI, 0.38-0.61) of breastfeeding for ≥6 months compared with NBW infants. Among black infants, a larger percentage of VLBW infants were breastfed for ≥6 months (26.2%) compared with LBW infants (14.9%). Breastfeeding rates for VLBW and NBW infants have improved over time. Both VLBW and NBW infants are close to meeting the Healthy People 2020 ever breastfeeding goal of 81.9%. LBW infants are farther from this goal than VLBW infants. The results suggest a need for policies that encourage breastfeeding specifically among LBW infants. Copyright © 2018 Elsevier Inc. All rights reserved.

Full Text Available The incidence of birth injuries has decreased considerably because of the identification of risk factors at an earlier stage and taking the decision for caesarian section (LSCS at proper time. Fractures, nerve palsies and central nervous system injuries comprise the majority of "birth injuries." In this study, we report a newborn that had a birth injury during LSCS. The baby sustained a penetrating abdominal injury by the knife of the surgeon, while performing LSCS. The bowel was injured at two sites, proximal jejunum and descending colon. The baby developed meconeum spillage and peritonitis. Exploratory laprotomy was done and the injuries were identified. The injured portions were resected and bowel continuity was reestablished. The baby had an uneventful recovery.

The birth beliefs scale - a new measure to assess basic beliefs about birth.

Preis, Heidi; Benyamini, Yael

Basic beliefs about birth as a natural and safe or a medical and risky process are central in the decisions on where and how to birth. Despite their importance, they have not been studied separately from other childbirth-related constructs. Our aim was to develop a measure to assess these beliefs. Pregnant Israeli women (N = 850, gestational week ≥14) were recruited in women's health centers, in online natural birth forums, and through home midwives. Participants filled in questionnaires including sociodemographic and obstetric background, the Birth Beliefs Scale (BBS), dispositional desire for control (DC) and planned mode of delivery. Factor analyses revealed that the BBS is composed of two factors: beliefs about birth as a natural process and beliefs about birth as a medical process. Both subscales showed good internal and test-retest reliability. They had good construct validity, predicted birth choices, and were weakly correlated with DC. Women's medical obstetric history was associated with the BBS, further supporting the validity of the scale. Beliefs about birth may be the building blocks that make up perceptions of birth and drive women's preferences. The new scale provides an easy way to distinctly assess them so they can be used to further understand planned birth behaviors. Additional studies are needed to comprehend how these beliefs form in different cultural contexts and how they evolve over time.

PLANNED HOME BIRTH: A REVIEW

Full Text Available Background: Home birth is as old as humanity, but still most middle- and high-income countries consider hospitals as the safest birth settings, as complications regarding birth are highly unpredictable. Despite this there are a few countries in which home birth in integrated into official healthcare system (the Netherlands, United Kingdom, Canada etc.. Home births can be divided into unplanned and planned, and the latter can be further categorized by the presence of the birth attendants. This review focuses on planned home births, which are differently represented throughout the world. In the United States 0.6-1.0% of all children are born at home, in the United Kingdom 2-3%, in Canada 1.6% and in the Netherlands 20-30%. For Slovenia, the number of planned home births is unknown; however, in 2010 0.1% of children were born outside medical facilities.Conclusions: The safety of home birth in still under the debate. While research confirms smaller number of obstetric interventions and some complications in mothers who give birth at home, the data regarding the neonatal and perinatal mortality and morbidity is still conflicting. This confirms the need for large multicentric trials in this field. Current home birth guidelines emphasize that women should be well informed regarding the possible advantages and disadvantages of home births. In addition, the emphasis is on definition of selection criteria for home birth, indications for intrapartal transfer to the hospital and appropriate education of birth attendants.

STUDY CONCERNING THE COSTS OF BIRTH BY CAESAREAN SECTION COMPARED TO NATURAL BIRTH

Full Text Available The birth by caesarean section has become an expanding phenomenon in the recent years, natural births being more and more rare in Romania. The increasing incidence of these operations has been observed in the recent years, in the conditions of more effective fetal monitoring, modification of the malpractice law and increasing degree of information of the women. In Romania, depending on the hospital, the percentage of births by caesarean section ranges between 20-80%, even 90% (these latter percentage being valid especially in private clinics. The percentage of the operations is higher in big cities, and in Bucharest about 70% of the births are done by C-section. The World Health Organization recommends a maximum percentage surgical intervention of 10-15%. Fearing the labor pain, more and more women are choosing to bring their children into the world by Caesarean section. Also the number of doctors who claim that cesarean section is a better option is increasing. Both persons involved in the birth process have the responsibility of that decision - meaning both mother and doctor. The option of the mother is very important, but the recommendation of the doctor can make the difference. The decision is not only of the doctor, he just presents the information that the mother does not know, mother's wish being the most important. In this paper we conducted a study to determine the comparative costs of the vaginal births with those by Caesarean section. The retrospective study was conducted between 01.01.2015 - 31.12.2015, on 3607 births registered in the Obstetrics and Gynecology Clinics of Clinical Emergency County Hospital Oradea. Gemellary births were excluded from the study. We analyzed the comparative costs of a vaginal birth and of a birth by caesarean section in order to highlight the share of cesarean births compared to vaginal births.

Effect of periodontal treatment on preterm birth rate: a systematic review of meta-analyses.

López, Néstor J; Uribe, Sergio; Martinez, Benjamín

2015-02-01

Preterm birth is a major cause of neonatal morbidity and mortality in both developed and developing countries. Preterm birth is a highly complex syndrome that includes distinct clinical subtypes in which many different causes may be involved. The results of epidemiological, molecular, microbiological and animal-model studies support a positive association between maternal periodontal disease and preterm birth. However, the results of intervention studies carried out to determine the effect of periodontal treatment on reducing the risk of preterm birth are controversial. This systematic review critically analyzes the methodological issues of meta-analyses of the studies to determine the effect of periodontal treatment to reduce preterm birth. The quality of the individual randomized clinical trials selected is of highest relevance for a systematic review. This article describes the methodological features that should be identified a priori and assessed individually to determine the quality of a randomized controlled trial performed to evaluate the effect of periodontal treatment on pregnancy outcomes. The AMSTAR and the PRISMA checklist tools were used to assess the quality of the six meta-analyses selected, and the bias domain of the Cochrane Collaboration's Tool was applied to evaluate each of the trials included in the meta-analyses. In addition, the methodological characteristics of each clinical trial were assessed. The majority of the trials included in the meta-analyses have significant methodological flaws that threaten their internal validity. The lack of effect of periodontal treatment on preterm birth rate concluded by four meta-analyses, and the positive effect of treatment for reducing preterm birth risk concluded by the remaining two meta-analyses are not based on consistent scientific evidence. Well-conducted randomized controlled trials using rigorous methodology, including appropriate definition of the exposure, adequate control of confounders for

2012-01-01

Full Text Available Background and Objectives: Low birth weight (LBW is a major public health problem. LBW is associated with increased neonatal morbidity and mortality. There is no consensus in the literature as to whether maternal copper nutrition is associated with pregnancy outcome or fetal growth. Methods: This case-control study was carried out at Alavi Hospital in Ardabil between August 2008 and August 2009. 56 women who had delivered low-birth- weight infants (<2500gr were taken as the case group, and from the mothers who had delivered normal birth weight infants (≥2500gr, 56 were selected at random as the control group. Venous blood samples were obtained from the mothers. Serum zinc level was determined by the Atomic Absorption Spectrophotometer method.Results: Mean of birth weight in infants, maternal age, body mass index in mothers and socioeconomic or demographic factors did not differ between cases and control groups. Maternal copper concentration (μg/dl differed between Cases and Controls; 231.75±38.12μg/dl vs. 204.42±31.30μg/dl respectively. There is a significant difference (p<0.001 in the serum copper concentration between the two groups.Conclusion: There is a negative relation between low infant birth weight and maternal copper concentration.

Full Text Available Abstract Background Caesarean section rates in Brazil have been steadily increasing. In 2009, for the first time, the number of children born by this type of procedure was greater than the number of vaginal births. Caesarean section is associated with a series of adverse effects on the women and newborn, and recent evidence suggests that the increasing rates of prematurity and low birth weight in Brazil are associated to the increasing rates of Caesarean section and labour induction. Methods Nationwide hospital-based cohort study of postnatal women and their offspring with follow-up at 45 to 60 days after birth. The sample was stratified by geographic macro-region, type of the municipality and by type of hospital governance. The number of postnatal women sampled was 23,940, distributed in 191 municipalities throughout Brazil. Two electronic questionnaires were applied to the postnatal women, one baseline face-to-face and one follow-up telephone interview. Two other questionnaires were filled with information on patients’ medical records and to assess hospital facilities. The primary outcome was the percentage of Caesarean sections (total, elective and according to Robson’s groups. Secondary outcomes were: post-partum pain; breastfeeding initiation; severe/near miss maternal morbidity; reasons for maternal mortality; prematurity; low birth weight; use of oxygen use after birth and mechanical ventilation; admission to neonatal ICU; stillbirths; neonatal mortality; readmission in hospital; use of surfactant; asphyxia; severe/near miss neonatal morbidity. The association between variables were investigated using bivariate, stratified and multivariate model analyses. Statistical tests were applied according to data distribution and homogeneity of variances of groups to be compared. All analyses were taken into consideration for the complex sample design. Discussion This study, for the first time, depicts a national panorama of labour and birth

High resolution white-light pictures of sunspot penumbrae are presented. These include pictures showing details of their filamentary structure and some instances of birth of a penumbra. The observations are discussed in the framework of current penumbra theories. A series of pictures have been presented, which give additional evidence of the existence of dark penumbral filaments as individual structures. With respect to the birth of the penumbra some new observational aspects can be seen. The existence of the filamentary penumbra even in the first moments, its non uniformity and its short length are the major aspects derived from the pictures

2012-12-01

We conducted a large registry-based study in California to investigate the association of perinatal factors and childhood leukemia with analysis of two major subtypes, acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML). We linked California cancer and birth registries to obtain information on 5788 cases and 5788 controls matched on age and sex (1:1). We examined the association of birth weight, gestational age, birth and pregnancy order, parental ages, and specific conditions during pregnancy and risk of total leukemia, ALL and AML using conditional logistic regression, with adjustment for potential confounders. The odds ratio (OR) per 1000 g increase in birth weight was 1.11 for both total leukemia and ALL. The OR were highest for babies weighing ≥ 4500 g with reference birth weight and LGA were associated with increased risk and SGA with decreased risk of total childhood leukemia and ALL, being first-born was associated with decreased risk of AML, and advanced paternal age was associated with increased risk of ALL. These findings suggest that associations of childhood leukemia and perinatal factors depend highly on subtype of leukemia. Copyright © 2012 Elsevier Ltd. All rights reserved.

2015-01-01

Objective We examine disparities in birth weight and gestational age by ethnic ancestry in 2000–2011 in eight South American countries. Methods The sample included 60480 singleton live-births. Regression models were estimated to evaluate differences in birth outcomes by ethnic ancestry controlling for time trends. Results Significant disparities were found in seven countries. In four countries – Brazil, Ecuador, Uruguay, and Venezuela – we found significant disparities in both low birth weight and preterm birth. Disparities in preterm birth alone were observed in Argentina, Bolivia, and Colombia. Several differences in continuous birth weight, gestational age, and fetal growth rate were also observed. There were no systematic patterns of disparities between the evaluated ethnic ancestry groups across the study countries, in that no racial/ethnic group consistently had the best or worst outcomes in all countries. Conclusions Racial/ethnic disparities in infant health are common in several South American countries. Differences across countries suggest that racial/ethnic disparities are driven by social and economic mechanisms. Researchers and policymakers should acknowledge these disparities and develop research and policy programs to effectively target them. PMID:25542227

French Guiana has the highest birth rate in South America. This French territory also has the highest premature birth rate and perinatal mortality rate of all French territories. The objective was to determine the premature birth rate and to identify the prevalence of risk factors of premature birth in French Guiana. A retrospective study of all births in French Guiana was conducted between January 2013 and December 2014 using the computerized registry compiling all live births over 22 weeks of gestation on the territory. During this period 12 983 live births were reported on the territory. 13.5% of newborns were born before 37 (1755/12 983). The study of the registry revealed that common sociodemographic risk factors of prematurity were present. In addition, past obstetrical history was also important: a scarred uterus increased the risk of prematurity adjusted odds ratio =1.4, 95%CI (1.2-1.6). Similarly, obstetrical surveillance, the absence of preparation for birth or of prenatal interview increased the risk of prematurity by 2.4 and 2.3, the excess fraction in the population was 69% and 72.2%, respectively. Known classical risk factors are important. In the present study excess fractions were calculated in order to prioritize interventions to reduce the prematurity rate.

Evolution of the Birth Plan

OpenAIRE

Kaufman, Tamara

2007-01-01

Many birth professionals are discarding the birth plan as an outdated and ineffectual document. This column discusses the past limitations and present uses of the birth plan in an effort to enhance current teaching on how expectant parents can write and use this important document. Encouraging expectant parents to prepare two separate, but corresponding, birth plans—the “Discussion Birth Plan” and the “Hospital Birth Plan”—is proposed. Teaching suggestions and possible implications are explor...

Background: Home birth is as old as humanity, but still most middle- and high-income countries consider hospitals as the safest birth settings, as complications regarding birth are highly unpredictable. Despite this there are a few countries in which home birth in integrated into official healthcare system (the Netherlands, United Kingdom, Canada etc.). Home births can be divided into unplanned and planned, and the latter can be further categorized by the presence of the birth attendants. Thi...

Few studies have investigated international variations in the gestational age (GA) distribution of births. While preterm births (22-36 weeks GA) and early term births (37-38 weeks) are at greater risk of adverse health outcomes compared to full term births (39-40 weeks), it is not known if countries with high preterm birth rates also have high early term birth rates. We examined rate associations between preterm and early term births and mean term GA by mode of delivery onset. We used routine aggregate data on the GA distribution of singleton live births from up to 34 high-income countries/regions in 1996, 2000, 2004, 2008 and 2010 to study preterm and early term births overall and by spontaneous or indicated onset. Pearson correlation coefficients were adjusted for clustering in time trend analyses. Preterm and early term births ranged from 4.1% to 8.2% (median 5.5%) and 15.6% to 30.8% (median 22.2%) of live births in 2010, respectively. Countries with higher preterm birth rates in 2004-2010 had higher early term birth rates (r > 0.50, P birth rates suggest that common risk factors could underpin shifts in the GA distribution. Targeting modifiable population risk factors for delivery before 39 weeks GA may provide a useful preterm birth prevention paradigm.

Our primary objective was to compare neonatal and maternal outcomes in women with twin pregnancies, beyond 32 weeks, having a planned vaginal birth or a planned caesarean section (CS). This was a retrospective cohort study from a single tertiary centre over nine years. 534 sets of twins ≥32 + 0 weeks of gestation were included. 401 sets were planned vaginally and 133 sets were planned by CS. We compared a composite adverse perinatal outcome (perinatal mortality or serious neonatal morbidity; five minute APGAR score ≤4, neurological abnormality and need for intubation) and a composite maternal adverse outcome (major haemorrhage, trauma or infection) between the groups. There were no significant differences. Given the similarity of these results with several other larger studies of twin birth, we sought to look at reasons why there is still a rising rate of CS for twin births. We further make suggestions for keeping this rate to a sensible minimum. Impact statement What is already known on this subject? The largest randomised controlled study comparing planned vaginal birth with planned CSs for lower risk twins between 32 and 39 weeks of gestation, showed no added safety from planned CS. However, in most of the Western countries this conclusion has failed to increase the number of planned vaginal births for lower risk twins. What do the results of this study add? This observational study from a single tertiary centre provides external validation of the twin trial results in a practical day-to-day setting. It also provides insights as to how planned vaginal birth can be developed and maintained, with a key focus on safety and maternal participation in decision making. It does focus on consent and providing accurate data. What are the implications of these findings for clinical practice and/or further research? There are good grounds to encourage vaginal birth for low-risk twin pregnancies. The trend of rising caesarean rates in low-risk twin

Anaemia in pregnancy is a major public health and economic problem worldwide, that contributes to both maternal and fetal morbidity and mortality. The aim of the study was to calculate the prevalence of anaemia in early pregnancy in a cohort of 'low risk' women participating in a large international multicentre prospective study (n = 5 609), to identify the modifiable risk factors for anaemia in pregnancy in this cohort, and to compare the birth outcomes between pregnancies with and without anaemia in early gestation. The study is an analysis of data that were collected prospectively during the Screening for Pregnancy Endpoints study. Anaemia was defined according to the World Health Organization's definition of anaemia in pregnancy (haemoglobin prevalence of anaemia (2.2%), that having no marital partner was an independent risk factor for having anaemia (OR 1.34, 95% CI 1.01-1.78), and that there was no statistically significant effect of anaemia on adverse pregnancy outcomes (small for gestational age, pre-tem birth, mode of delivery, low birth weight, APGAR score pregnancy outcomes were however more common in those with anaemia than in those without. In this low risk healthy pregnant population we found a low anaemia rate. The absence of a marital partner was a non-modifiable factor, albeit one which may reflect a variety of confounding factors, that should be considered for addition to anaemia's conceptual framework of determinants. Although not statistically significant, clinically, a trend towards a higher risk of adverse pregnancy outcomes was observed in women that were anaemic in early pregnancy.

Rowlands Ingrid J

2012-11-01

Full Text Available Abstract Background Physical and psychological problems after childbirth are common, and may have a significant negative and long-term impact on women’s wellbeing and daily functioning. The method of birth may be a particularly important factor influencing women’s health and wellbeing following birth, however, population-wide evidence is limited. This study uses data from 5,332 women who responded to a national survey of women’s experiences of maternity care in England. We examined women’s postnatal wellbeing in the first three months after birth, and whether these varied by mode of birth. Methods This is a secondary analysis of survey data using a random sample of women selected from birth registration. We used multinomial logistic regression models to examine the association between women’s self-reported psychological symptoms, health problems and mode of birth. Results Women who had forceps-assisted vaginal births and unplanned caesarean section births reported the poorest health and wellbeing, while those of women who had unassisted vaginal births and planned caesarean section births were less affected by the birth process. Most women’s physical and emotional health appeared to improve with time, however, those who had a forceps-assisted vaginal birth were more likely to report ongoing posttraumatic-type symptoms several months after the birth. Conclusions Mode of birth was associated with differences in outcomes at three months. By comparison to women who had unassisted vaginal births, the risk of reduced postnatal health and wellbeing was higher amongst the women who had forceps-assisted vaginal births but not amongst women who had ventouse-assisted vaginal births. This would suggest that it is important to differentiate the different types of instrumental birth in outcome studies. Of concern was the higher rate of posttraumatic-type symptoms among women who had forceps-assisted vaginal births relative to the other modes of

The Matrix Metalloproteases and Endothelin-1 in Infection-Associated Preterm Birth

Directory of Open Access Journals (Sweden)

Nicole S. Olgun

2010-01-01

Full Text Available Preterm birth (PTB is clinically defined as any delivery which occurs before the completion of 37 weeks of gestation, and is currently the most important problem in obstetrics. In the United States, PTB accounts for 12-13% of all live births, and, with the exception of fetuses suffering from anomalies, is the primary cause of perinatal mortality. While the risk factors for PTB are numerous, the single most common cause is intrauterine infection. As there is currently no FDA-approved therapy for infection-associated PTB, understanding the pathogenesis of preterm labor (PTL and delivery should be given high priority. The matrix metalloproteinases (MMPs are a family of enzymes that have been implicated in normal parturition as well as infection-triggered rupture of membranes and preterm birth. Several lines of evidence also suggest a role for endothelin-1 (ET-1 in infection-associated preterm delivery. This paper focuses on the evidence that the MMPs and ET-1 act in the same molecular pathway in preterm birth.

Socioeconomic inequality in preterm birth in four Brazilian birth cohort studies

Directory of Open Access Journals (Sweden)

Ana Daniela Izoton de Sadovsky

Full Text Available Abstract Objective: To analyze economic inequality (absolute and relative due to family income in relation to the occurrence of preterm births in Southern Brazil. Methods: Four birth cohort studies were conducted in the years 1982, 1993, 2004, and 2011. The main exposure was monthly family income and the primary outcome was preterm birth. The inequalities were calculated using the slope index of inequality and the relative index of inequality, adjusted for maternal skin color, education, age, and marital status. Results: The prevalence of preterm births increased from 5.8% to approximately 14% (p-trend < 0.001. Late preterm births comprised the highest proportion among the preterm births in all studies, although their rates decreased over the years. The analysis on the slope index of inequality demonstrated that income inequality arose in the 1993, 2004, and 2011 studies. After adjustment, only the 2004 study maintained the difference between the poorest and the richest subjects, which was 6.3 percentage points. The relative index of inequality showed that, in all studies, the poorest mothers were more likely to have preterm newborns than the richest. After adjustment for confounding factors, it was observed that the poorest mothers only had a greater chance of this outcome in 2004. Conclusion: In a final model, economic inequalities resulting from income were found in relation to preterm births only in 2004, although a higher prevalence of prematurity continued to be observed in the poorest population, in all the studies.

Labor pain and its management is a major concern for childbearing women, their families and health care providers. This study aimed to investigate the effects of two non-pharmacological methods such as birth ball and heat therapy on labor pain relief. This randomized control trial was undertaken on 90 primiparous women aged 18-35 years old who were randomly assigned to two intervention (birth ball and heat) and control groups. The pain score was recorded by using Visual Analogue Scale (VAS) before the intervention and every 30 min in three groups until cervical dilatation reached 8 cm. The mean pain severity score in the heat therapy group was less than that of in control group at 60 and 90 min after intervention (p pain scores in the birth ball group after all three investigated times in comparison to control group. Both heat therapy and birth ball can use as inexpensive complementary and low risk treatment for labor pain. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Survival of extremely low birth weight (ELBW and extremely premature (EP infants has shown consistent improvement thanks to advances and innovations in perinatal and neonatal care. Regionalization, with high-risk deliveries in a tertiary perinatal center, offers the coordinated, collaborative, expert and specialized care needed by these mothers and their infants. Despite decreasing rates of the major neonatal morbidities observed in recent years, these continue still to be significant for ELBW/EP infants, impacting their overall prognosis. After NICU discharge and in the first years of life, issues with health, growth and development are common. In school age and adolescence, problems with behavior, socialization and cognition are prevalent. Adult outcomes of ELBW/EP need further clarity, emphasizing the importance for consistent long-term follow-up for this special cohort. Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in Neonatology Guest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa, Apostolos Papageorgiou

Intake of colostrum after birth is essential to stimulate intestinal growth and function, and to provide systemic immunological protection via absorption of Immunoglobulin G (IgG). The birth order and weight of 745 piglets (from 75 litters) were recorded during a one-week period of farrowing. Only pigs weighing greater than 0.68 kg birth weight were chosen for the trial. Sow colostrum was collected during parturition, and piglets were bled between 48 and 72 hours post-birth. Piglet serum IgG and colostral IgG concentrations were determined by radial immunodiffusion. Sow parity had a significant (P birth order accounted for another 4% of the variation observed in piglet serum IgG concentration (P birth weight had no detectable effect. Piglet serum IgG concentration had both a linear (P Birth order had no detectable effect on survival, but birth weight had a positive linear effect (P birth had a 68% survival rate, and those weighing 1.6 kg (n = 158) had an 89% survival. We found that the combination of sow colostrum IgG concentration and birth order can account for 10% of the variation of piglet serum IgG concentration and that piglets with less than 1,000 mg/dl IgG serum concentration and weight of 0.9 kg at birth had low survival rate when compared to their larger siblings. The effective management of colostrum uptake in neonatal piglets in the first 24 hrs post-birth may potentially improve survival from birth to weaning.

Association between Birth Characteristics and Cardiovascular Autonomic Function at Mid-Life.

Full Text Available Low birth weight is associated with an increased risk of cardiovascular diseases in adulthood. As abnormal cardiac autonomic function is a common feature in cardiovascular diseases, we tested the hypothesis that low birth weight may also be associated with poorer cardiac autonomic function in middle-aged subjects.At the age of 46, the subjects of the Northern Finland Birth Cohort 1966 were invited to examinations including questionnaires about health status and life style and measurement of vagally-mediated heart rate variability (rMSSD from R-R intervals (RRi and spontaneous baroreflex sensitivity (BRS in both seated and standing positions. Maternal parameters had been collected in 1965-1966 since the 16th gestational week and birth variables immediately after delivery. For rMSSD, 1,799 men and 2,279 women without cardiorespiratory diseases and diabetes were included and 902 men and 1,020 women for BRS. The analyses were adjusted for maternal (age, anthropometry, socioeconomics, parity, gestational smoking and adult variables (life style, anthropometry, blood pressure, glycemic and lipid status potentially confounding the relationship between birth weight and autonomic function.In men, birth weight correlated negatively with seated (r = -0.058, p = 0.014 and standing rMSSD (r = -0.090, p<0.001, as well as with standing BRS (r = -0.092, p = 0.006. These observations were verified using relevant birth weight categories (<2,500 g; 2,500-3,999 g; ≥4,000 g. In women, birth weight was positively correlated with seated BRS (r = 0.081, p = 0.010, but none of the other measures of cardiovascular autonomic function. These correlations remained significant after adjustment for potential confounders (p<0.05 for all.In men, higher birth weight was independently associated with poorer cardiac autonomic function at mid-life. Same association was not observed in women. Our findings suggest that higher, not lower, birth weight in males may contribute to less

Contaminated sport fish consumption may result in exposure to various reproductive and developmental toxicants, including pesticides and other suspected endocrine disruptors. We investigated the relation between maternal sport fish meals and risk of major birth defects among infants born to members of the New York State (NYS) Angler Cohort between 1986 and 1991 (n=2237 births). Birth defects (n=125 cases) were ascertained from both newborn medical records and the NYS Congenital Malformations Registry. For sport fish meals eaten during pregnancy, the odds ratio (OR) for all major malformations combined was slightly elevated for or =2 meals/month (OR=1.51, CI=0.74, 3.09), with no meals during pregnancy as the reference category. Higher ORs were consistently observed among male offspring compared with females. For > or =2 meals/month, the risk for males was significantly elevated (males: OR=3.01, CI: 1.2, 7.5; females: OR=0.73, CI: 0.2, 2.4). Exposure during pregnancy and effect modification by infants sex could be important considerations for future studies of birth outcomes associated with endocrine disruptors.

Although assisted reproductive techniques are commonly applied in humans and animals, they are frequently associated with major developmental deficits and reduced viability. To explore abnormalities associated with cloning or nuclear transfer (NT) as the most invasive of these methods, we used a bovine model to characterize abnormalities. Detailed necropsy examinations were done on 13 calves that died soon after birth; in addition, we included data from embryos and fetuses (produced by NT) that terminated prematurely. Bovine clones that survived until the neonatal period differed quantitatively and qualitatively from in-vivo-derived cattle. Although alterations affected a variety of organs (e.g. heart, lung and liver), there was a clear association with abberant vascular developmental during the early intrauterine phase. Therefore, we concluded that vascular problems were key alterations induced by cloning (presumably via epigenetic modifications). PMID:25584533

to examine the relationship between attitudes towards home birth and birth outcomes, and whether women's attitudes towards birth and intervention affected this relationship. a prospective cohort study. the study was set in Iceland, a sparsely populated island with harsh terrain, 325,000 inhabitants, high fertility and home birth rates, and less than 5000 births a year. a convenience sample of women who attended antenatal care in Icelandic health care centres, participated in the Childbirth and Health Study in 2009-2011, and expressed consistent attitudes towards home birth (n=809). of the participants, 164 (20.3%) expressed positive attitudes towards choosing home birth and 645 (79.7%) expressed negative attitudes. Women who had a positive attitude towards home birth had significantly more positive attitudes towards birth and more negative attitudes towards intervention than did women who had a negative attitude towards home birth. Of the 340 self-reported low-risk women that answered questionnaires on birth outcomes, 78 (22.9%) had a positive attitude towards home birth and 262 (77.1%) had a negative attitude. Oxytocin augmentation (19.2% (n=15) versus 39.1% (n=100)), epidural analgesia (19.2% (n=15) versus 33.6% (n=88)), and neonatal intensive care unit admission rates (0.0% (n=0) versus 5.0% (n=13)) were significantly lower among women who had a positive attitude towards home birth. Women's attitudes towards birth and intervention affected the relationship between attitudes towards home birth and oxytocin augmentation or epidural analgesia. the beneficial effect of planned home birth on maternal outcome in Iceland may depend to some extent on women's attitudes towards birth and intervention. Efforts to de-stigmatise out-of-hospital birth and de-medicalize women's attitudes towards birth might increase women׳s use of health-appropriate birth services. Copyright © 2016 Elsevier Ltd.

to explore the experiences of a small group of first-time mothers giving birth at home or in hospital. a grounded theory methodology was used. Data were generated from in-depth interviews with women in their own homes. Sydney, Australia. 19 women were interviewed. Seven women who gave birth for the first time in a public hospital and seven women who gave birth for the first time at home were interviewed, and their experiences were contrasted with two mothers who gave birth for the first time in a birth centre, one mother who gave birth for the first time in a private hospital and two women who had given birth more than once. these women shared common experiences of giving birth as 'novices'. Regardless of birth setting, they were all 'reacting to the unknown'. As they entered labour, the women chose different levels of responsibility for their birth. They also readjusted their expectations when the reality of labour occurred, reacted to the 'force' of labour, and connected or disconnected from the labour and eventually the baby. knowing that first-time mothers, irrespective of birth setting, are essentially 'reacting to the unknown' as they negotiate the experience of birth, could alter the way in which care is provided and increase the sensitivity of midwives to women's needs. Most importantly, midwives need to be aware of the need to help women adjust their expectations during labour and birth. Identifying the 'novice' status of first-time mothers also better explains previous research that reports unrealistic expectations and fear that may be associated with first-time birthing.

Li, Qing; Jenkins, Dorothea D; Kinsman, Stephen L

2017-05-01

Objective Neonatal seizures in the first 28 days of life often reflect underlying brain injury or abnormalities, and measure the quality of perinatal care in out-of-hospital births. Using the 2003 revision of birth certificates only, three studies reported more neonatal seizures recorded among home births ​or planned out-of-hospital births compared to hospital births. However, the validity of recording neonatal seizures or serious neurologic dysfunction across birth settings in birth certificates has not been evaluated. We aimed to validate seizure recording in birth certificates across birth settings using multiple datasets. Methods We examined checkbox items "seizures" and "seizure or serious neurologic dysfunction" in the 1989 and 2003 revisions of birth certificates in South Carolina from 1996 to 2013. Gold standards were ICD-9-CM codes 779.0, 345.X, and 780.3 in either hospital discharge abstracts or Medicaid encounters jointly. Results Sensitivity, positive predictive value, false positive rate, and the kappa statistic of neonatal seizures recording were 7%, 66%, 34%, and 0.12 for the 2003 revision of birth certificates in 547,177 hospital births from 2004 to 2013 and 5%, 33%, 67%, and 0.09 for the 1998 revision in 396,776 hospital births from 1996 to 2003, and 0, 0, 100%, -0.002 among 660 intended home births from 2004 to 2013 and 920 home births from 1996 to 2003, respectively. Conclusions for Practice Despite slight improvement across revisions, South Carolina birth certificates under-reported or falsely reported seizures among hospital births and especially home births. Birth certificates alone should not be used to measure neonatal seizures or serious neurologic dysfunction.

OBJECTIVE No randomized controlled trial has directly compared vaginal progesterone and cervical cerclage for the prevention of preterm birth in women with a sonographic short cervix in the midtrimester, singleton gestation, and previous spontaneous preterm birth. We performed an indirect comparison of vaginal progesterone versus cerclage, using placebo/no cerclage as the common comparator. STUDY DESIGN Adjusted indirect meta-analysis of randomized controlled trials. RESULTS Four studies evaluating vaginal progesterone versus placebo (158 patients) and five evaluating cerclage versus no cerclage (504 patients) were included. Both interventions were associated with a statistically significant reduction in the risk of preterm birth <32 weeks of gestation and composite perinatal morbidity and mortality compared with placebo/no cerclage. Adjusted indirect meta-analyses did not show statistically significant differences between vaginal progesterone and cerclage in reducing preterm birth or adverse perinatal outcomes. CONCLUSION Based on state-of-the-art methodology for indirect comparisons, either vaginal progesterone or cerclage are equally efficacious in the prevention of preterm birth in women with a sonographic short cervix in the midtrimester, singleton gestation, and previous preterm birth. The selection of the optimal treatment may depend upon adverse events, cost and patient/clinician preferences. PMID:23157855

To examine the prospective association between symptoms commonly experienced during pregnancy and the mental and general health status of women 14 years post partum. Data used were from the Mater-University of Queensland Study of Pregnancy, a community-based prospective birth cohort study begun in Brisbane, Australia, in 1981. Logistic regression analyses were conducted. Data were available for 5118 women. Women who experienced a higher burden of symptoms during pregnancy were at greater risk of becoming depressed and reporting poorer health status 14 years post partum. Women who experienced major problems during pregnancy were 4 times more likely to be depressed and nearly 8 times more likely to report poorer health status 14 years after the index pregnancy compared with women who experienced few problems. Findings suggest that pregnant women who experience common symptoms during pregnancy are likely to experience poorer mental and self-reported general health 14 years after the pregnancy.

Tea, a common beverage, has been suggested to exhibit a number of health benefits. However, one of its active ingredients, caffeine, has been associated with preterm birth and low birthweight. We investigated whether tea consumption during early pregnancy is associated with an increased risk of preterm birth and abnormal fetal growth. A total of 8775 pregnant women were included from the Born in Guangzhou Cohort Study. Tea consumption (type, frequency, and strength) during their first trimester and social and demographic factors were obtained by way of questionnaires administered during pregnancy. Information on birth outcomes and complications during pregnancy was obtained from hospital medical records. Overall habitual tea drinking (≥1 serving/week) prevalence among pregnant women was low, at 16%. After adjustment for potential confounding factors (eg, maternal age, educational level, monthly income) tea drinking during early pregnancy was not associated with an increased risk of preterm birth or abnormal fetal growth (small or large for gestational age) (P>.05). We did not identify a consistent association between frequency of tea consumption or tea strength and adverse birth outcomes among Chinese pregnant women with low tea consumption. Our findings suggest that occasional tea drinking during pregnancy is not associated with increased risk of preterm birth or abnormal fetal growth. Given the high overall number of annual births in China, our findings have important public health significance. © 2017 Wiley Periodicals, Inc.

To study the association between atopy and variables such as weight, length, and socioeconomic level at birth and in young adulthood. A total of 2,063 subjects were investigated in a prospective birth cohort study of individuals born in Ribeirão Preto, Brazil, in 1978/1979, and examined at the age of 23-25 years. Skin prick tests (SPT) for eight common allergens in Brazil were performed. Subjects with a wheal reaction ≥ 3 mm to one or more of the eight allergens tested were considered to be atopic. We used the log-binomial model (generalized linear model) in order to assess the association between atopy and birth or adult variables. The prevalence of positive SPT was 47.6%. Male gender was associated with an increased risk of atopy (relative risk [RR] = 1.18; 95% confidence interval [95%CI] 1.07-1.30). Low level of schooling was a protective factor against atopy, with a RR = 0.74; 95%CI 0.62-0.89. Living with a smoker in childhood was also associated with lower risk of atopy (RR = 0.87; 95%CI 0.79-0.96). Birth weight, length and order, maternal age, and intrauterine growth restriction were not associated with positive SPT. This study showed that male gender was associated with an increased risk of atopy. Low socioeconomic status, assessed by low level of schooling, was a protective factor against atopy. These data agree with the hygiene hypothesis.

The transition to newborn life at birth involves major cardiovascular changes that are triggered by lung aeration. These include a large increase in pulmonary blood flow (PBF), which is required for pulmonary gas exchange and to replace umbilical venous return as the source of preload for the left heart. Clamping the umbilical cord before PBF increases reduces venous return and preload for the left heart and thereby reduces cardiac output. Thus, if ventilation onset is delayed following cord clamping, the infant is at risk of superimposing an ischemic insult, due to low cardiac output, on top of an asphyxic insult. Much debate has centered on the timing of cord clamping at birth, focusing mainly on the potential for a time-dependent placental to infant blood transfusion. This has prompted recommendations for delayed cord clamping for a set time after birth in infants not requiring resuscitation. However, recent evidence indicates that ventilation onset before cord clamping mitigates the adverse cardiovascular consequences caused by immediate cord clamping. This indicates that the timing of cord clamping should be based on the infant's physiology rather than an arbitrary period of time and that delayed cord clamping may be of greatest benefit to apneic infants.

Lundberg, Evelina; Svaleryd, Helena

2017-01-01

Previous research has established that birth order affects outcomes such as educational achievements, IQ and earnings. The mechanisms behind these effects are, however, still largely unknown. In this paper, we examine birth-order effects on health, and whether health at young age could be a transmission channel for birth-order effects observed later in life. We find no support for the birth-order effect having a biological origin; rather firstborns have worse health at birth. This disadvantag...

Full Text Available The birth interval is a major determinant of levels of fertility in high fertility populations. A house-to-house survey of 1225 women in Manipur, a tiny state in North Eastern India was carried out to investigate birth interval patterns and its determinants. Using survival analysis, among the nine explanatory variables of interest, only three factors – infant mortality, Lactation and use of contraceptive devices have highly significant effect (P<0.01 on the duration of birth interval and only three factors – age at marriage of wife, parity and sex of child are found to be significant (P<0.05 on the duration variable.

Studies of planned home births attended by registered midwives have been limited by incomplete data, nonrepresentative sampling, inadequate statistical power and the inability to exclude unplanned home births. We compared the outcomes of planned home births attended by midwives with those of planned hospital births attended by midwives or physicians. We included all planned home births attended by registered midwives from Jan. 1, 2000, to Dec. 31, 2004, in British Columbia, Canada (n = 2889), and all planned hospital births meeting the eligibility requirements for home birth that were attended by the same cohort of midwives (n = 4752). We also included a matched sample of physician-attended planned hospital births (n = 5331). The primary outcome measure was perinatal mortality; secondary outcomes were obstetric interventions and adverse maternal and neonatal outcomes. The rate of perinatal death per 1000 births was 0.35 (95% confidence interval [CI] 0.00-1.03) in the group of planned home births; the rate in the group of planned hospital births was 0.57 (95% CI 0.00-1.43) among women attended by a midwife and 0.64 (95% CI 0.00-1.56) among those attended by a physician. Women in the planned home-birth group were significantly less likely than those who planned a midwife-attended hospital birth to have obstetric interventions (e.g., electronic fetal monitoring, relative risk [RR] 0.32, 95% CI 0.29-0.36; assisted vaginal delivery, RR 0.41, 95% 0.33-0.52) or adverse maternal outcomes (e.g., third- or fourth-degree perineal tear, RR 0.41, 95% CI 0.28-0.59; postpartum hemorrhage, RR 0.62, 95% CI 0.49-0.77). The findings were similar in the comparison with physician-assisted hospital births. Newborns in the home-birth group were less likely than those in the midwife-attended hospital-birth group to require resuscitation at birth (RR 0.23, 95% CI 0.14-0.37) or oxygen therapy beyond 24 hours (RR 0.37, 95% CI 0.24-0.59). The findings were similar in the comparison with

Cognitive impairment has been identified as an important aspect of major depressive disorder (MDD). We tested two theories regarding the association between MDD and cognitive functioning using data from longitudinal cohort studies. One theory, the cognitive reserve hypothesis, suggests that higher cognitive ability in childhood decreases risk of later MDD. The second, the scarring hypothesis, instead suggests that MDD leads to persistent cognitive deficits following disorder onset. We tested both theories in the Dunedin Study, a population-representative cohort followed from birth to midlife and assessed repeatedly for both cognitive functioning and psychopathology. We also used data from the Environmental Risk Longitudinal Twin Study to test whether childhood cognitive functioning predicts future MDD risk independent of family-wide and genetic risk using a discordant twin design. Contrary to both hypotheses, we found that childhood cognitive functioning did not predict future risk of MDD, nor did study members with a past history of MDD show evidence of greater cognitive decline unless MDD was accompanied by other comorbid psychiatric conditions. Our results thus suggest that low cognitive functioning is related to comorbidity, but is neither an antecedent nor an enduring consequence of MDD. Future research may benefit from considering cognitive deficits that occur during depressive episodes from a transdiagnostic perspective.

Common variation in ISL1 confers genetic susceptibility for human congenital heart disease.

Directory of Open Access Journals (Sweden)

Kristen N Stevens

Full Text Available Congenital heart disease (CHD is the most common birth abnormality and the etiology is unknown in the overwhelming majority of cases. ISLET1 (ISL1 is a transcription factor that marks cardiac progenitor cells and generates diverse multipotent cardiovascular cell lineages. The fundamental role of ISL1 in cardiac morphogenesis makes this an exceptional candidate gene to consider as a cause of complex congenital heart disease. We evaluated whether genetic variation in ISL1 fits the common variant-common disease hypothesis. A 2-stage case-control study examined 27 polymorphisms mapping to the ISL1 locus in 300 patients with complex congenital heart disease and 2,201 healthy pediatric controls. Eight genic and flanking ISL1 SNPs were significantly associated with complex congenital heart disease. A replication study analyzed these candidate SNPs in 1,044 new cases and 3,934 independent controls and confirmed that genetic variation in ISL1 is associated with risk of non-syndromic congenital heart disease. Our results demonstrate that two different ISL1 haplotypes contribute to risk of CHD in white and black/African American populations.

We sought to evaluate perinatal morbidity by delivery location (hospital, freestanding birth center, and home). Selected 2006 US birth certificate data were accessed online from the Centers for Disease Control and Prevention. Low-risk maternal and newborn outcomes were tabulated and compared by birth facility. A total of 745,690 deliveries were included, of which 733,143 (97.0%) occurred in hospital, 4661 (0.6%) at birth centers, and 7427 (0.9%) at home. Compared with hospital deliveries, home and birthing center deliveries were associated with more frequent prolonged and precipitous labors. Home births experienced more frequent 5-minute Apgar scores home and birthing center deliveries were associated with less frequent chorioamnionitis, fetal intolerance of labor, meconium staining, assisted ventilation, neonatal intensive care unit admission, and birthweight Home births are associated with a number of less frequent adverse perinatal outcomes at the expense of more frequent abnormal labors and low 5-minute Apgar scores.

2016-08-01

Full Text Available Background: Jaundice is a common clinical condition in newborn occurring in approximately 60% of term and 80% of preterm infants. Unconjugated hyperbilirubinemia is universally common in all preterm infants especially in newborns with very low biLth weight. Low birth weight and premature infants are at major risk for exaggerated hyperbilirubinemia that can lead to bilirubin encephalopathy. Significant heterogeneity in the approach to the treatment of jaundiced neonates exists throughout the world. Phototherapy is the most common treatment for neonatal hyperbilirubinemia and could be most effective in preventing the sequelae of hyperbilirubinemia if initiated prophylactically. This randomized clinical trial has been proposed with the objective of assessing the efficacy of prophylactic photo therapy in preventing significant rise of unconjugated hyperbilirubinemia in premature neonates weighing less than 1500 gram and therefore to decrease the need for exchange transfusion and finally to reduce hospital stay due to hyperbilirubinemia. Methods: This randomized controlled clinical trial enrolled sixty newborns with birth weight less than 1500 gram. They were divided into two groups: 1 Prophylactic group, in whom phototherapy was started within 24 hours of birth and continued for 7 days and 2 Control group in whom therapeutic phototherapy was started considering serum bilirubin level and other clinical condi­tions as per institutional guidelines. Mean value of total serum bilirubin (TSB, duration of phototherapy, the need for exchange transfusion and duration of hospital stay in both groups were analyzed.Results: The maximum mean TSB level in prophylactic group was observed on 7th day and in control group it was observed on 3rd day of life. The total serum bilirubin levels were significantly lower in the 3rd and 5th days of life in the prophylactic group in comparison to control group (P value 0.001. Total serum bilirubin level exceeded therapeutic

To determine the predictive ability of acculturation as an antecedent of stress, biobehavioral risk, corticotropin-releasing hormone levels, and poor birth outcomes in pregnant Hispanic women. A prospective, observational design with data collected at 22-25 weeks of gestation and at birth through medical record review. Public prenatal health clinics in south Texas serving low-income women. Self-identified Hispanic women who had singleton pregnancies, no major medical risk complications, and consented to answer questionnaires as well as a venipuncture and review of their prenatal and birth medical records. Gestational age, Apgar scores, length, weight, percentile size, and head circumference of the infant at birth. Significant differences were seen in infant birth weight, head circumference, and percentile size by acculturation. English acculturation predicted stress, corticotropin-releasing hormone, biobehavioral risk, and decreased gestational age at birth. Investigation must continue to understand the circumstances that give rise to the decline in birth outcomes observed in Hispanics with acculturation to the dominant English culture in the United States.

1999-05-01

To assess the association between physical violence during the 12 months before delivery and maternal complications and birth outcomes. We used population-based data from 6143 women who delivered live-born infants between 1993 and 1995 in South Carolina. Data on women's physical violence during pregnancy were based on self-reports of "partner-inflicted physical hurt and being involved in a physical fight." Outcome data included maternal antenatal hospitalizations, labor and delivery complications, low birth weights, and preterm births. Odds ratios and 95% confidence intervals were calculated to measure the associations between physical violence, maternal morbidity, and birth outcomes. The prevalence of physical violence was 11.1%. Among women who experienced physical violence, 54% reported having been involved in physical fights only and 46% had been hurt by husbands or partners. In the latter group, 70% also reported having been involved in fighting. Compared with those not reporting physical violence, women who did were more likely to deliver by cesarean and be hospitalized before delivery for maternal complications such as kidney infection, premature labor, and trauma due to falls or blows to the abdomen. Physical violence during the 12 months before delivery is common and is associated with adverse maternal conditions. The findings support the need for research on how to screen for physical violence early in pregnancy and to prevent its consequences.

Narcissism and birth order.

Eyring, W E; Sobelman, S

1996-04-01

The purpose of this investigation was to clarify the relationship between birth-order position and the development of narcissism, while refining research and theory. The relationship between birth-order status and narcissism was examined with a sample of 79 undergraduate students (55 women and 24 men). These subjects were placed in one of the four following birth-order categories of firstborn, second-born, last-born, and only children. These categories were chosen given their significance in Adlerian theory. Each subject completed the Narcissistic Personality Inventory and a demographic inventory. Based on psychodynamic theory, it was hypothesized that firstborn children were expected to score highest, but statistical significance was not found for an association between narcissism and birth order. Further research is urged to investigate personality theory as it relates to parenting style and birth order.

This report presents 2004 data on U.S. births according to a wide variety of characteristics. Data are presented for maternal demographic characteristics including age, live-birth order, race, Hispanic origin, marital status, and educational attainment; maternal lifestyle and health characteristics (medical risk factors, weight gain, and tobacco use); medical care utilization by pregnant women (prenatal care, obstetric procedures, characteristics of labor and/or delivery, attendant at birth, and method of delivery); and infant characteristics (period of gestation, birthweight, Apgar score, congenital anomalies, and multiple births). Also presented are birth and fertility rates by age, live-birth order, race, Hispanic origin, and marital status. Selected data by mother's state of residence are shown, as well as data on month and day of birth, sex ratio, and age of father. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. Descriptive tabulations of data reported on the birth certificates of the 4.1 million births that occurred in 2004 are presented. Denominators for population-based rates are post-censal estimates derived from the U.S. 2000 census. In 2004, 4,112,052 births were registered in the United States, less than 1 percent more than the number in 2003. The crude birth rate declined slightly; the general fertility rate increased by less than 1 percent. Childbearing among teenagers and women aged 20-24 years declined to record lows. Rates for women aged 25-34 and 45-49 years were unchanged, whereas rates for women aged 35-44 years increased. All measures of unmarried childbearing rose in 2004. Smoking during pregnancy continued to decline. No improvement was seen in the timely initiation of prenatal care. The cesarean delivery rate jumped 6 percent to another all-time high, whereas the rate of vaginal birth after previous cesarean fell by 13 percent. Preterm and low birthweight rates continued their steady rise

Secondary recurrent miscarriage is associated with previous male birth.

Secondary recurrent miscarriage (RM) is defined as three or more consecutive pregnancy losses after delivery of a viable infant. Previous reports suggest that a firstborn male child is associated with less favourable subsequent reproductive potential, possibly due to maternal immunisation against male-specific minor histocompatibility antigens. In a retrospective cohort study of 85 cases of secondary RM we aimed to determine if secondary RM was associated with (i) gender of previous child, maternal age, or duration of miscarriage history, and (ii) increased risk of pregnancy complications. Fifty-three women (62.0%; 53\\/85) gave birth to a male child prior to RM compared to 32 (38.0%; 32\\/85) who gave birth to a female child (p=0.002). The majority (91.7%; 78\\/85) had uncomplicated, term deliveries and normal birth weight neonates, with one quarter of the women previously delivered by Caesarean section. All had routine RM investigations and 19.0% (16\\/85) had an abnormal result. Fifty-seven women conceived again and 33.3% (19\\/57) miscarried, but there was no significant difference in failure rates between those with a previous male or female child (13\\/32 vs. 6\\/25, p=0.2). When patients with abnormal results were excluded, or when women with only one previous child were considered, there was still no difference in these rates. A previous male birth may be associated with an increased risk of secondary RM but numbers preclude concluding whether this increases recurrence risk. The suggested association with previous male birth provides a basis for further investigations at a molecular level.

, the SGA outcome remained significant only in women with mean body mass index (BMI ≥ 22 kg/m2. There was an increased risk of neonatal mortality in studies with majority of births at home [RR = 1.47, 95% CI: 1.13-1.92]; such an effect was not evident where ≥ 60% of births occurred in facility settings [RR = 0.94, 95% CI: 0.81-1.09]. Overall there was no increase in the risk of neonatal mortality [RR = 1.05, 95% CI: 0.92 – 1.19 (fixed model]. Conclusion This review provides evidence of a significant benefit of MMN supplementation during pregnancy on reducing SGA births as compared to iron-folate, with no significant increase in the risk of neonatal mortality in populations where skilled birth care is available and majority of births take place in facilities. Given comparability of impacts on maternal anemia, the decision to replace iron-folate with multiple micronutrients during pregnancy may be taken in the context of available services in health systems and birth outcomes monitored.

Transfer in planned home births in Sweden--effects on the experience of birth: a nationwide population-based study.

Lindgren, Helena E; Rådestad, Ingela J; Hildingsson, Ingegerd M

2011-08-01

More than 10% of all planned home births in high-income countries are completed in the hospital. The aim of this study was to compare the birth experiences among women who planned to give birth at home and completed the birth at home and women who were transferred to hospital during or immediately after the birth. All women in Sweden who had a planned home birth between 1998 and 2005 (n=671) were invited to participate in the study. The women who agreed to participate received one questionnaire for each planned home birth. Mixed methods were used for the analysis. Women who had been transferred during or immediately after the planned home birth had a more negative birth experience in general. In comparison with women who completed the birth at home, the odds ratio for being less satisfied was 13.5, CI 8.1-22.3. Reasons for being dissatisfied related to organizational factors, the way the women were treated or personal ability. Being transferred during a planned home birth negatively affects the birth experience. Treatments as well as organizational factors are considered to be obstacles for a positive birth experience when transfer is needed. Established links between the home birth setting and the hospital might enhance the opportunity for a positive birth experience irrespective of where the birth is completed.

Full Text Available Delivery before 37th week of gestation is defined as preterm, independently of body mass of babies, according to the World Health Organization. Premature birth is the current problem in the world due to the high risk of neonatal morbidity and mortality and incompletely clear etiology. In our country the frequency of preterm delivery is 6%. We have retrospectively analyzed early deliveries in Health Center Kosovska Mitrovica in the period from 2009 to 2013. In this five-year period, there were totaly 3398 deliveries, of which 148 or 4.35 % were preterm delivery. The aim of this study was to investigate the incidence of premature birth in the five-year period in relation to: the total number of births in a given period, the age of the patients, the manner of completion of delivery, gestational week of pregnancy, parity and the most common causes that led to the PTP. In the analysis we have included the body weight and Apgar score of premature infants. We have used protocols of births, maternal history of disease, neonatal protocols and lists of newborns. Most of them were multiparas (41.2 %,56.7 % of pregnant women were aged of 21-30 years and pregnancy in 79.9 % of cases ended with 33 to 37 ng. Vaginal deliveries were completed in 84.4% of premature births, and caesarean in 15.6%. Twin pregnancies with preterm deliveries were represented in 10.2%. The most common weight of premature infants ranged from 2000 to 2500 grams (48.6 %. The most common causes that led to the PTP were PPROM (22.9 %, unknown causes (27. 1 %, multiple pregnancy (18.2 %, genital infection (8.7 %, cervical incompetence (6.7 %, IUGR (5.4%, PIH (4.2%, placental abruption and placenta previa (2.1 % and other (4.7% .

Around 86% of births in Mumbai, India, occur in healthcare institutions, but this aggregate figure hides substantial variation and little is known about urban home births. We aimed to explore factors influencing the choice of home delivery, care practices and costs, and to identify characteristics of women, households and the environment which might increase the likelihood of home birth. As part of the City Initiative for Newborn Health, we used a key informant surveillance system to identify births prospectively in 48 slum communities in six wards of Mumbai, covering a population of 280,000. Births and outcomes were documented prospectively by local women and mothers were interviewed in detail at six weeks after delivery. We examined the prevalence of home births and their associations with potential determinants using regression models. We described 1708 (16%) home deliveries among 10,754 births over two years, 2005-2007. The proportion varied from 6% to 24%, depending on area. The most commonly cited reasons for home birth were custom and lack of time to reach a healthcare facility during labour. Seventy percent of home deliveries were assisted by a traditional birth attendant (dai), and 6% by skilled health personnel. The median cost of a home delivery was US$ 21, of institutional delivery in the public sector US$ 32, and in the private sector US$ 118. In an adjusted multivariable regression model, the odds of home delivery increased with illiteracy, parity, socioeconomic poverty, poorer housing, lack of water supply, population transience, and hazardous location. We estimate 32,000 annual home births to residents of Mumbai's slums. These are unevenly distributed and cluster with other markers of vulnerability. Since cost does not appear to be a dominant disincentive to institutional delivery, efforts are needed to improve the client experience at public sector institutions. It might also be productive to concentrate on intensive outreach in vulnerable areas by

The authors examined the prevalence of congenital malformations among births in Benton and Franklin counties, in southeastern Washington State, from 1968 through 1980. The Hanford Site is in this area and serves as a major employer. In addition, various agriculturally and chemically related activities are in the area. Hospital and vital records were used to identify 454 malformation cases among 23,319 births; this yielded a malformation rate of 19.6 per 1000 births, a rate similar to those reported in other studies. The rates of specific malformations ascertained during the first year of life were compared with combined rates from the states of Washington, Oregon, and Idaho from the Birth Defects Monitoring Program. Among defects that would be expected to be comparably ascertained, a statistically significant elevated rate of neural tube defects was observed (1.72 per 1000 births vs. 0.99 per 1000). Rates of cleft lip were significantly lower in Benton and Franklin counties than in the Birth Defects Monitoring Program (0.59 per 1,000 vs. 1.17 per 1000). For congenital heart defects, pyloric stenosis, and Down syndrome, which are often not diagnosed in the newborn period, Birth Defects Monitoring Program data did not offer appropriate comparisons. The rates of these defects did not appear to be elevated in relation to rates found in other relevant populations. When rates of neural tube defects were compared with those in populations other than the Birth Defects Monitoring Program, the Benton and Franklin county rates were still considered to be elevated. The increased bicounty rate cannot be explained by employment of the parents at Hanford or by the impact of plant emissions on the local population

The male-to-female sex ratio at birth is constant across world populations with an average of 1.06 (106 male to 100 female live births) for populations of European descent. The sex ratio is considered to be affected by numerous biological and environmental factors and to have a heritable component. The aim of this study was to investigate the presence of common allele modest effects at autosomal and chromosome X variants that could explain the observed sex ratio at birth. We conducted a large-scale genome-wide association scan (GWAS) meta-analysis across 51 studies, comprising overall 114 863 individuals (61 094 women and 53 769 men) of European ancestry and 2 623 828 common (minor allele frequency >0.05) single-nucleotide polymorphisms (SNPs). Allele frequencies were compared between men and women for directly-typed and imputed variants within each study. Forward-time simulations for unlinked, neutral, autosomal, common loci were performed under the demographic model for European populations with a fixed sex ratio and a random mating scheme to assess the probability of detecting significant allele frequency differences. We do not detect any genome-wide significant (P < 5 × 10−8) common SNP differences between men and women in this well-powered meta-analysis. The simulated data provided results entirely consistent with these findings. This large-scale investigation across ∼115 000 individuals shows no detectable contribution from common genetic variants to the observed skew in the sex ratio. The absence of sex-specific differences is useful in guiding genetic association study design, for example when using mixed controls for sex-biased traits. PMID:22843499

The high rate of home deliveries conducted by unskilled birth attendants in resource-limited settings is an important global health issue because it is believed to be a significant contributing factor to maternal and newborn mortality. Given the large number of deliveries that are managed by unskilled or traditional birth attendants outside of health facilities, and the fact that there is on-going discussion regarding the role of traditional birth attendants in the maternal newborn health (MNH) service continuum, we sought to ascertain the practices of traditional birth attendants in our catchment area. The findings of this descriptive study might help inform conversations regarding the roles that traditional birth attendants can play in maternal-newborn health care. A structured questionnaire was used in a survey that included one hundred unskilled birth attendants in western Kenya. Descriptive statistics were employed. Inappropriate or outdated practices were reported in relation to some obstetric complications and newborn care. Encouraging results were reported with regard to positive relationships that traditional birth attendants have with their local health facilities. Furthermore, high rates of referral to health facilities was reported for many common obstetric emergencies and similar rates for reporting of pregnancy outcomes to village elders and chiefs. Potentially harmful or outdated practices with regard to maternal and newborn care among traditional birth attendants in western Kenya were revealed by this study. There were high rates of traditional birth attendant referrals of pregnant mothers with obstetric complications to health facilities. Policy makers may consider re-educating and re-defining the roles and responsibilities of traditional birth attendants in maternal and neonatal health care based on the findings of this survey.

Contaminated sport fish consumption may result in exposure to various reproductive and developmental toxicants, including pesticides and other suspected endocrine disruptors. We investigated the relation between maternal sport fish meals and risk of major birth defects among infants born to members of the New York State (NYS) Angler Cohort between 1986 and 1991 (n=2237 births). Birth defects (n=125 cases) were ascertained from both newborn medical records and the NYS Congenital Malformations Registry. For sport fish meals eaten during pregnancy, the odds ratio (OR) for all major malformations combined was slightly elevated for ≤1 meal/month (OR=1.26, 95% confidence interval (CI): 0.84, 1.89) and ≥2 meals/month (OR=1.51, CI=0.74, 3.09), with no meals during pregnancy as the reference category. Higher ORs were consistently observed among male offspring compared with females. For ≥2 meals/month, the risk for males was significantly elevated (males: OR=3.01, CI: 1.2, 7.5; females: OR=0.73, CI: 0.2, 2.4). Exposure during pregnancy and effect modification by infants sex could be important considerations for future studies of birth outcomes associated with endocrine disruptors

We sought to systematically review the medical literature on the maternal and newborn safety of planned home vs planned hospital birth. We included English-language peer-reviewed publications from developed Western nations reporting maternal and newborn outcomes by planned delivery location. Outcomes' summary odds ratios with 95% confidence intervals were calculated. Planned home births were associated with fewer maternal interventions including epidural analgesia, electronic fetal heart rate monitoring, episiotomy, and operative delivery. These women were less likely to experience lacerations, hemorrhage, and infections. Neonatal outcomes of planned home births revealed less frequent prematurity, low birthweight, and assisted newborn ventilation. Although planned home and hospital births exhibited similar perinatal mortality rates, planned home births were associated with significantly elevated neonatal mortality rates. Less medical intervention during planned home birth is associated with a tripling of the neonatal mortality rate. Copyright 2010 Mosby, Inc. All rights reserved.

The rate of twin pregnancies in the United States has stabilized at 32 per 1000 births in 2006. Aside from determining chorionicity, first-trimester screening and second-trimester ultrasound scanning should ascertain whether there are structural or chromosomal abnormalities. Compared with singleton births, genetic amniocentesis-related loss at births is higher (0.9% vs 2.9%, respectively). Selective termination for an anomalous fetus is an option, although the pregnancy loss rate is 7% at experienced centers. For singleton and twin births for African American and white women, approximately 50% of preterm births are indicated; approximately one-third of these births are spontaneous, and 10% of the births occur after preterm premature rupture of membranes. From 1989-2000, the rate of preterm twin births increased, for African American and white women alike, although the perinatal mortality rate has actually decreased. As with singleton births, tocolytics should be used judiciously and only for a limited time (births. Administration of antenatal corticosteroids is an evidence-based recommendation.

The unprecedented increase in multiple births during the past 3 decades is a major public health concern and parallels the uptake of medically assisted conception. The economic implications of such births are not well understood. To conduct a comprehensive economic and health services assessment of the frequency, duration, and cost of hospital admissions during the first 5 years of life for singleton, twin, and higher-order multiple (HOM) children and to examine the contribution of assisted reproductive technology (ART) to the incidence and cost of multiple births. A retrospective population cohort study using individually linked birth, hospital, and death records among 233,850 infants born in Western Australia between October 1993 and September 2003, and followed up to September 2008. Multiple-gestation delivery and ART conception. Odds of stillbirth, prematurity and low birth weight, frequency and length of hospital admissions, the mean costs by plurality, and the independent effect of prematurity on childhood costs. Of 226,624 singleton, 6941 twin, and 285 HOM infants, 1.0% of singletons, 15.4% of twins, and 34.7% of HOM children were conceived following ART. Compared with singletons, twins and HOMs were 3.4 and 9.6 times, respectively, more likely to be stillborn and were 6.4 and 36.7 times, respectively, more likely to die during the neonatal period. Twins and HOMs were 18.7 and 525.1 times, respectively, more likely to be preterm, and 3.6 and 2.8 times, respectively, more likely to be small for gestational age. The mean hospital costs of a singleton, twin, and HOM child to age 5 years were $2730, $8993, and $24,411 (in 2009-2010 US dollars), respectively, with cost differences concentrated in the neonatal period and during the first year of life. Almost 15% of inpatient costs for multiple births could have been avoided if ART twins and HOMs had been born as singletons. Compared with singletons, multiple-birth infants consume significantly more hospital

It has been shown that childhood mortality is affected by parental socioeconomic positions; in this article, we investigate the extent and distribution of inequalities across major causes of childhood death. We built a retrospective birth cohort using individually linked national birth and death records in South Korea. 1,329,540 children were followed up to exact age eight from 1995 to 1996 and total observed person-years were 10,594,168.18. Causes of death were identified from death records while parental education, occupation and birth characteristics were identified from birth records. Survival analysis was performed according to parental socioeconomic positions. Cox proportional hazard analysis was done according to parental education and occupation with adjustment of birth characteristics such as sex, parental age, gestational age, birth weight, multiple birth, the number of total births, and previous death of children. Cumulative incidence of mortality by age was obtained through a competing-risk method in each cause according to maternal education. From these results, distribution of inequalities across major causes of death was calculated. In total, 7018 deaths occurred during the eight years and mortality rate was 66.24 per 100,000 person-years. External cause was the most common cause of death followed by congenital malformations, nervous system diseases, perinatal diseases, cancer, respiratory, cardiovascular, infectious and gastrointestinal diseases. For all-cause mortality, hazard ratios (HR) were 1.98 (95% CI: 1.83-2.13) for paternal education, 1.90 (1.75-2.07) for maternal education, 1.40 (1.33-1.47) for paternal occupation and 2.33(1.98-2.73) for maternal occupation (between middle school graduation or lower and university or more for education, between manual and non-manual for occupation). Mortality differentials were found in every cause of death. External cause, respiratory, cardiovascular and infectious diseases showed larger HR than all

Stoll, Kathrin; Hall, Wendy

2013-01-01

In our secondary analysis of a cross-sectional survey, we explored predictors of childbirth fear for young women (n = 2,676). Young women whose attitudes toward pregnancy and birth were shaped by the media were 1.5 times more likely to report childbirth fear. Three factors that were associated with reduced fear of birth were women's confidence in reproductive knowledge, witnessing a birth, and learning about pregnancy and birth through friends. Offering age-appropriate birth education during primary and secondary education, as an alternative to mass-mediated information about birth, can be evaluated as an approach to reduce young women's childbirth fear.

This report presents preliminary data for 2000 on births in the United States. U.S. data on births are shown by age, race, and Hispanic origin of mother. Data on marital status, prenatal care, cesarean delivery, and low birthweight are also presented. Data in this report are based on more than 96 percent of births for 2000. The records are weighted to independent control counts of births received in State vital statistics offices in 2000. Comparisons are made with 1999 final data. The number of births rose 3 percent between 1999 and 2000. The crude birth rate increased to 14.8 per 1,000 population in 2000, 2 percent higher than the 1999 rate. The fertility rate rose 3 percent to 67.6 per 1,000 women aged 15-44 years between 1999 and 2000. The birth rate for teenagers, which has been falling since 1991, declined 2 percent in 2000 to 48.7 births per 1,000 females aged 15-19 years, another historic low. The rate for teenagers 15-17 years fell 4 percent, and the rate for 18-19 year olds was down 1 percent. Since 1991, rates have fallen 29 percent for teenagers 15-17 years and 16 percent for teenagers 18-19 years. Birth rates for all of the older age groups increased for 1999-2000: 1 percent among women aged 20-24 years, 3 percent for women aged 25-29 years, and 5 percent for women in their thirties. Rates for women aged 40-54 years were also up for 2000. The birth rate for unmarried women increased 2 percent to 45.2 births per 1,000 unmarried women aged 15-44 years in 2000, but was still lower than the peak reached in 1994. The number of births to unmarried women was up 3 percent, the highest number ever reported in the United States. However, the number of births to unmarried teenagers declined. The proportion of women who began prenatal care in the first trimester of pregnancy (83.2 percent) did not improve for 2000, nor did the rate of low birthweight (7.6 percent). The total cesarean rate rose for the fourth consecutive year to 22.9 percent, the result of both a

The birth order puzzle.

Science.gov (United States)

Zajonc, R B; Markus, H; Markus, G B

1979-08-01

Studies relating intellectual performance to birth order report conflicting results, some finding intellectual scores to increase, others to decrease with birth order. In contrast, the relationship between intellectual performance and family size is stable and consistently replicable. Why do these two highly related variables generate such divergent results? This birth order puzzle is resolved by means of the confluence model that quantifies the influences upon intellectual growth arising within the family context. At the time of a new birth, two opposing influences act upon intellectual growth of the elder sibling: (a) his or her intellectual environment is "diluted" and (b) he or she loses the "last-born's handicap" and begins serving as an intellectual resource to the younger sibling. Since these opposite effects are not equal in magnitude, the differences in intellectual performance among birth ranks are shown to be age dependent. While elder children may surpass their younger siblings in intellectual performance at some ages, they may be overtaken by them at others. Thus when age is taken into consideration, the birth order literature loses its chaotic character and an orderly pattern of results emerges.

The Chernobyl accident, the male to female ratio at birth and birth rates.

Grech, Victor

2014-01-01

The male:female ratio at birth (male births divided by total live births - M/T) has been shown to increase in response to ionizing radiation due to gender-biased fetal loss, with excess female loss. M/T rose sharply in 1987 in central-eastern European countries following the Chernobyl accident in 1986. This study analyses M/T and births for the former Soviet Republics and for the countries most contaminated by the event. Annual birth data was obtained from the World Health Organisation. The countries with the highest exposure levels (by ¹³⁷Cs) were identified from an official publication of the International Atomic Energy Agency. All of the former Soviet states were also analysed and the periods before and after 1986 were compared. Except for the Baltic States, all regions in the former USSR showed a significant rise in M/T from 1986. There were significant rises in M/T in the three most exposed (Belarus, Ukraine and the Russian Federation). The birth deficit in the post-Soviet states for the ten years following Chernobyl was estimated at 2,072,666, of which 1,087,924 are accounted by Belarus and Ukraine alone. Chernobyl has resulted in the loss of millions of births, a process that has involved female even more than male fetuses. This is another and oft neglected consequence of widespread population radiation contamination.

Full Text Available Abstract Background Intake of colostrum after birth is essential to stimulate intestinal growth and function, and to provide systemic immunological protection via absorption of Immunoglobulin G (IgG. The birth order and weight of 745 piglets (from 75 litters were recorded during a one-week period of farrowing. Only pigs weighing greater than 0.68 kg birth weight were chosen for the trial. Sow colostrum was collected during parturition, and piglets were bled between 48 and 72 hours post-birth. Piglet serum IgG and colostral IgG concentrations were determined by radial immunodiffusion. Results Sow parity had a significant (P Conclusion We found that the combination of sow colostrum IgG concentration and birth order can account for 10% of the variation of piglet serum IgG concentration and that piglets with less than 1,000 mg/dl IgG serum concentration and weight of 0.9 kg at birth had low survival rate when compared to their larger siblings. The effective management of colostrum uptake in neonatal piglets in the first 24 hrs post-birth may potentially improve survival from birth to weaning.

Full Text Available Audience: This scenario was developed to educate emergency medicine residents on the management of a precipitous birth in the emergency department (ED. The case is also appropriate for teaching of medical students and advanced practice providers, as well as reviewing the principles of crisis resource management, teamwork, and communication. Introduction: Patients with precipitous birth require providers to manage two patients simultaneously with limited time and resources. Crisis resource management skills will be tested once baby is delivered, and the neonate will require assessment for potential neonatal resuscitation. Objectives: At the conclusion of the simulation session, learners will be able to manage women who have precipitous deliveries, as well as perform neonatal assessment and management. Method: This session was conducted using high-fidelity simulation, followed by a debriefing session and lecture on precipitous birth management and neonatal evaluation.

Although there is evidence to tracking progress towards facility births within the UN Millennium Development Goals framework, we do not know whether women are deciding against home birth over their reproductive lives. Using Demographic and Health Surveys (DHS) data from 44 countries, this study aims to investigate the patterns and shifts in childbirth locations and to determine whether these shifts are in favour of home or health settings. The analyses considered 108,777 women who had at least two births in the five years preceding the most recent DHS over the period 2000-2010. The vast majority of women opted for the same place of childbirth for their successive births. However, about 14% did switch their place and not all these decisions favoured health facility over home setting. In 24 of the 44 countries analysed, a higher proportion of women switched from a health facility to home. Multilevel regression analyses show significantly higher odds of switching from home to a facility for high parity women, those with frequent antenatal visits and more wealth. However, in countries with high infant mortality rates, low parity women had an increased probability of switching from home to a health facility. There is clear evidence that women do change their childbirth locations over successive births in low and middle income countries. After two decades of efforts to improve maternal health, it might be expected that a higher proportion of women will be deciding against home births in favour of facility births. The results from this analysis show that is not the case.

There is little research on HIV awareness and practices of traditional birth attendants (TBA) in India. This study investigated knowledge and attitudes among rural TBA in Karnataka as part of a project examining how traditional birth attendants could be integrated into prevention-of-mother-to-child transmission of HIV (PMTCT) programs in India. A cross-sectional survey was conducted between March 2008 and January 2009 among TBA in 144 villages in Mysore Taluk, Karnataka. Following informed consent, TBA underwent an interviewer-administered questionnaire in the local language of Kannada on practices and knowledge around birthing and HIV/PMTCT. Of the 417 TBA surveyed, the median age was 52 years and 96% were Hindus. A majority (324, 77.7%) had no formal schooling, 88 (21.1%) had up to 7 years and 5 (1%) had more than 7 yrs of education. Only 51 of the 417 TBA (12%) reported hearing about HIV/AIDS. Of those who had heard about HIV/AIDS, only 36 (72%) correctly reported that the virus could be spread from mother to child; 37 (74%) identified unprotected sex as a mode of transmission; and 26 (51%) correctly said healthy looking people could spread HIV. Just 22 (44%) knew that infected mothers could lower the risk of transmitting the virus to their infants. An overwhelming majority of TBA (401, 96.2%) did not provide antenatal care to their clients. Over half (254, 61%) said they would refer the woman to a hospital if she bled before delivery, and only 53 (13%) felt referral was necessary if excessive bleeding occurred after birth. Traditional birth attendants will continue to play an important role in maternal child health in India for the foreseeable future. This study demonstrates that a majority of TBA lack basic information about HIV/AIDS and safe delivery practices. Given the ongoing shortage of skilled birth attendance in rural areas, more studies are needed to examine whether TBA should be trained and integrated into PMTCT and maternal child health programs in

About 150 planned home births take place in Norway annually. Professionals have different opinions on whether such births are safe or not. The aim of the present study was to perform a systematic literature review on maternal and neonatal outcomes after planned home births. A review was performed of literature retrieved from searches in MEDLINE, PubMed, Embase, Cinahl and The Cochrane Library and relevant references found in the articles. The searches were limited to studies published in 1985 and later. 10 studies with data from 30 204 women who had planned and were selected to home birth at the onset of labour were included. Three of the studies had control groups including women with planned hospital births. All included studies were assessed to be of medium quality. Between 9.9 and 23.1 % of women and infants were transferred to hospital during labour or after birth. There were few caesarean sections, other interventions or complications in the studies assessed; the total perinatal mortality rate was 2.9/1000 and the intrapartum mortality rate 0.8/1000. There is no sound basis for discouraging low-risk women from planning a home birth. Results from the included studies do not directly apply to Norwegian conditions. Outcomes and transfers after planned home births should be systematically registered.

Childbirth fear is the most common underlying reason for requesting a caesarean section without medical reason. The aim of this randomised controlled study was to investigate birth preferences in women undergoing treatment for childbirth fear, and to investigate birth experience and satisfaction with the allocated treatment. Pregnant women classified with childbirth fear (≥60 on the Fear Of Birth Scale) (n=258) were recruited at one university hospital and two regional hospitals over one year. The participants were randomised (1:1) to intervention (Internet-based Cognitive Behaviour Therapy (ICBT)) (n=127) or standard care (face-to-face counselling) (n=131). Data were collected by questionnaires in pregnancy week 20-25 (baseline), week 36 and two months after birth. Caesarean section preference decreased from 34% to 12% in the ICBT group and from 24% to 20% in the counselling group. Two months after birth, the preference for caesarean increased to 20% in the ICBT group and to 29% in the counselling group, and there was no statistically significant change over time. Women in the ICBT group were less satisfied with the treatment (OR 4.5). The treatment had no impact on or worsened their childbirth fear (OR 5.5). There were no differences between the groups regarding birth experience. Women's birth preferences fluctuated over the course of pregnancy and after birth regardless of treatment method. Women felt their fear was reduced and were more satisfied with face-to-face counselling compared to ICBT. A higher percentage were lost to follow-up in ICBT group suggesting a need for further research. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

Maternal short stature: A risk factor for low birth weight in neonates

Directory of Open Access Journals (Sweden)

Vipin Chandra Kamathi

2012-08-01

Full Text Available Low birth weight (LBW is the most common cause of perinatal mortality, causing almost 30 percent of neonatal deaths. On the other hand, maternal short stature is known to cause a lot of obstetric complications like cephalopelvic disproportion and arrest of labor, intrauterine asphyxia, intrauterine growth retardation. The objective of our study was to find out whether there was any significant statistical association between maternal height and the birth weight of the neonate. We identified a group of low birth weight neonates (n=54 and a control group (n=51 of normal weight neonates at term in Mediciti Hospital over a period of 1 year and retrospectively looked the maternal heights for both groups. Inclusion criteria being mothers who delivered at term, mothers who had a hemoglobin level more than 10 gm/dl, mothers with relatively uneventful antenatal without any significant obstetric or medical complications during the pregnancy, and neonates with relatively uneventful post-natal periods without any significant pediatric or medical complications. The odds of having been born of a mother of short stature are more than three times greater for a low birth weight baby than a normal weight baby. The mean of birth weights of babies born to mothers of normal height is more than the mean of birth weights of babies born to mothers of short stature by 277.01 gm. This study reaffirms the observation that maternal height has a direct effect on the weight of the newborn and we propose that maternal short stature be identified as an independent risk factor for low birth weight.

Victor Grech

2014-01-01

Full Text Available Introduction: The male:female ratio at birth (male births divided by total live births – M/T has been shown to increase in response to ionizing radiation due to gender-biased fetal loss, with excess female loss. M/T rose sharply in 1987 in central-eastern European countries following the Chernobyl accident in 1986. This study analyses M/T and births for the former Soviet Republics and for the countries most contaminated by the event. Methods: Annual birth data was obtained from the World Health Organisation. The countries with the highest exposure levels (by 137Cs were identified from an official publication of the International Atomic Energy Agency. All of the former Soviet states were also analysed and the periods before and after 1986 were compared. Results: Except for the Baltic States, all regions in the former USSR showed a significant rise in M/T from 1986. There were significant rises in M/T in the three most exposed (Belarus, Ukraine and the Russian Federation. The birth deficit in the post-Soviet states for the ten years following Chernobyl was estimated at 2,072,666, of which 1,087,924 are accounted by Belarus and Ukraine alone. Discussion: Chernobyl has resulted in the loss of millions of births, a process that has involved female even more than male fetuses. This is another and oft neglected consequence of widespread population radiation contamination.

Preterm birth is the leading cause of perinatal morbidity and mortality worldwide, and is the most important challenge to modern obstetrics. A major obstacle has been that preterm birth is treated (implicitly or explicitly) as a single condition. Two-thirds of preterm births occur after the spontaneous onset of labor, and the remaining one-third after “indicated” preterm birth; however, the causes of spontaneous preterm labor and “indicated” preterm birth are different. Spontaneous preterm birth is a syndrome caused by multiple etiologies, one of which is a decline in progesterone action, which induces cervical ripening. A sonographic short cervix (identified in the midtrimester) is a powerful predictor of spontaneous preterm delivery. Randomized clinical trials and individual patient meta-analyses have shown that vaginal progesterone reduces the rate of preterm delivery at cervix, and therefore, the compound of choice is natural progesterone (not the synthetic progestin). Routine assessment of the risk of preterm birth with cervical ultrasound coupled with vaginal progesterone for women with a short cervix is cost-effective, and implementation of such a policy is urgently needed. Vaginal progesterone is as effective as cervical cerclage in reducing the rate of preterm delivery in women with a singleton gestation, history of preterm birth, and a short cervix (<25mm).

Magnitude and Correlates of Low Birth Weight at Term in Rural Wardha, Central India

Directory of Open Access Journals (Sweden)

Kumar V

2016-05-01

Full Text Available Introduction: Birth weight is one of the most important determinant of the neonatal and infant survival. The goal of reducing low birth weight incidence by at least one third between 2000 and 2010 was one of the major goals in ‘A World Fit for Children’. The prevention of low birth weight is a public health priority, particularly in developing countries with high magnitude. Knowledge regarding magnitude and correlates help prevent the condition. Hence, the present study was carried out to study the magnitude and the correlates of low birth weight. Methodology: Two hundred and six newborn babies were recruited on a birth cohort from two Primary Health Centres (PHC of Wardha district to study growth in first year of life. Here, we present the baseline analysis of 172 children who were born full term to study the correlates of low birth weight babies born full term. The children were recruited within first week of their birth. Data was collected on socio-demographic profile, birth history, and maternal characteristics. Proportion of low birth weight was expressed in percentage along with 95% confidence interval. Univariate and multivariate logistic regression was used to study the correlates. Findings are expressed in odds ratios with their 95% confidence intervals. Results: The magnitude of low birth weight at term was found to be 33.1% (95% CI: 26.4%-40.4%. On univariate analysis, significant correlates of low birth weight were consumption of less than 50 iron-folic acid tables and being born to than mother. On multivariate analysis, the significant correlates were female sex of child (OR=2.856, being born to thin mother (OR=5.320, consumption of less than 50 tablets (OR=4.648, and complications of pregnancy (OR=2.917. Conclusions: The magnitude of low birth weight is very high and modifiable correlates of low birth weight are nutritional status of mother, lower consumption of IFA tablets and complications of pregnancy.

Astrological birth signs in suicide: hypothesis or speculation?

2003-04-01

Astrology is no longer regarded as a science by many, because its claims are almost impossible to test empirically in controlled laboratory conditions and it can not meet the scientific need to be reproducible. However, the majority of those who read their 'star signs' can identify aspects of their personality in what they read and it is possible that this may influence their attitudes and actions. The literature has neglected astrological signs as a possible predictor of suicide ideation. To see whether astrological birth signs are associated with suicide and the method used, data was collected from the Public Health Department in North Cheshire representing all the Cheshire Coroner's verdicts of suicide, and open verdicts, in all deceased aged 60 and above between 1989 and 2000. The observed occurrence of deaths due to natural causes, and suicide, in relation to birth signs did not differ significantly from what would be expected from chance. However, the distribution of suicide by hanging appeared significantly higher in those with a birth sign of Virgo and lowest in Sagittarius and Scorpio. The distribution of violent and non-violent suicides in relation to star signs showed higher occurences of violent death in persons born in the summer months.

Metformin is generally considered a non-teratogenic drug; however, only a few studies specifically designed to assess the rate of congenital anomalies after metformin use have been published in the literature. The objects of the present study were to review all of the prospective and retrospective studies reporting on women treated with metformin at least during the first trimester of their pregnancy and to estimate the overall rate of major birth defects. Databases were searched for English language articles until December 2013. Inclusion criteria for the meta-analysis were: a case group of women with PCOS or pre-pregnancy type 2 diabetes and first-trimester exposure to metformin; a disease-matched control group which was not exposed to metformin or other oral anti-diabetic agents; and a list of the major anomalies in both the study and the control groups. A random effects model was used for the meta-analysis of data, using odds ratios. Studies not fulfilling the inclusion criteria for the meta-analysis but reporting relevant data on major malformations in women diagnosed with PCOS were then used to estimate the overall birth defects rate. Meta-analysis of nine controlled studies with women affected by PCOS detected that the rate of major birth defects in the metformin-exposed group was not statistically increased compared with the disease-matched control group and that there was no significant heterogeneity among the studies. The metformin-exposed sample was composed of 351 pregnancies and the OR of major birth defects was 0.86 (95% confidence interval: 0.18-4.08; Pheterogeneity = 0.71). By evaluating all of the non-overlapping PCOS studies reported in the literature, even those without an appropriate control group, the overall rate of major anomalies was 0.6% in the sample of 517 women who discontinued the therapy upon conception or confirmation of pregnancy and 0.5% in the sample of 634 women who were treated with metformin throughout the first trimester of

this study aimed to (1) assess the prevalence, and demographic features of women with a history of mental illness during pregnancy and childbirth, (2) investigate maternal and perinatal outcomes in relation to mental illness and substance use, and (3) determine the effects of maternal characteristics, history of mental illness and substance use on birth outcomes. the records of 22,193 pregnant women who gave birth at one tertiary level health service comprising three maternity settings in Victoria, Australia from 2009 to 2011 were reviewed.Univariate comparisons for socio-demographic and birthing outcome variables by substance use and mental illness category were performed. A multivariable logistic regression model was developed to examine the effects of maternal characteristics on birth outcomes. mental illness was recorded for 1.08/1,000 delivery hospitalisations.Mothers with a history of mental illness had a significantly higher proportion of babies born with low birth weight (OR = 1.85, 95% CI 1.64 -2.09) and low Apgar 1 scoresmental illness and substance use on birth weight. This interaction effect was not significant for gestational age. Logistic regression showed the strongest predictor of reporting a premature birth and low birth weight was using substances, recording an odds ratio of 1.95 (95% CI 1.50-2.53) and 2.73 (95% CI 2.15-3.47) respectively. mental health history should be highlighted as being a common morbidity and the increased risk of poorer birth outcomes especially when the women were also using substances, alcohol or tobacco should be acknowledged by the health practitioners.

Full Text Available Background and Objective: Adequate antenatal care and skilled obstetric assistance during delivery are important strategies that significantly reduce maternal mortality and morbidity. This study aimed to assess the awareness, attitudes and perception of orthodox health care centres among pregnant women patronizing traditional birth attendants in Mushin and Lagos Island local government areas of Lagos state. Methods: The survey was a community-based descriptive cross-sectional survey that employed interviews to collect data from 300 antenatal care attendees of seven traditional birth attendants′ clinics in Lagos Island and Mushin local government areas between December 2010 and January 2011 using a structured questionnaire. Results: The women ranged in age from 17-43 years with a mean age of 27.6 ± 4.6 SD and most of them were primigravidas (41.5%, married (88% and traders (44.1%. Most of the women (61% and their husbands (56.7% had completed their secondary education. The majority (81.7% of respondents were aware of a modern health facility around where they lived, the most commonly known being private hospitals (43.7%. Most of them (67.3% were aware of antenatal care services provided at these facilities but only 31.3% had ever made use of the antenatal services. Most of the women were not willing to deliver in hospitals because they didn′t like the attitude of the health workers (37.3% and because it was far from their houses (12.7%; the majority (75% preferring to deliver with traditional birth attendants because they give good service. However, almost all (98.5% of the women that had children took them to the orthodox health facilities for immunization, primarily the primary health care centers (55.7%. Conclusion: Traditional birth attendants are patronized by a wide array of women who are aware of orthodox health facilities but have a negative attitude towards their services.

The present study tested whether various sociodemographic, anthropometric, behavioral, and medical/physiological factors act in a direct or indirect manner on the risk of prematurity using path analysis on a sample of Israeli births. The path model shows that medical complications, primarily toxemia, chorioammionitis, and a previous low birth weight delivery directly and significantly act on the risk of prematurity as do low maternal pregnancy weight gain and ethnicity. Other medical complications, including chronic hypertension, preclampsia, and placental abruption, although significantly correlated with prematurity, act indirectly on prematurity through toxemia. The model further shows that the commonly accepted sociodemographic, anthropometric, and behavioral risk factors act by modifying the development of medical complications that lead to prematurity as opposed to having a direct effect on premature delivery. © 1996 Wiley-Liss, Inc.

Reasons Why Women Choose Home Birth

Directory of Open Access Journals (Sweden)

Mary Angelie P. Andrino

2016-11-01

Full Text Available Maternal deaths in the Philippines remain high. These deaths are mostly due to the large proportion of home births, complications of pregnancy and delivery, and lack of access to facilities and competently trained staff. Utilizing a descriptive, one-shot survey design, the study aimed to determine the reasons why women in a municipality in Iloilo prefer home birth. The respondents were interviewed using a validated questionnaire. Descriptive statistics were used to analyze and interpret the findings. The study revealed that the proportion of home births progressively declined from 2012 to 2014. Birth being imminent or inevitable is the number one reason that supports home birth. Autonomy, safety, affordability, readily available birthing equipment and supplies, accessibility of birth attendant, remote access by going to the birthing center, lack of transportation, and bad weather conditions also led women to give birth at home. Women from the rural areas of the municipality utilized available resources in the community which prompted the predominance of home deliveries assisted by traditional birth attendants (TBAs and even midwives, who were readily available nearby. This study recommends continuous improvement in existing maternal health interventions and strategies through engagement of women in policy planning, improvement of health service delivery, infrastructural enhancement, better care practices and continuous health education.

Full Text Available Background Preterm birth is a leading cause of perinatal morbidity and mortality and represents a major public health problem. It is associated with a 15–20 per cent mortality rate and remains responsible for 75 per cent of perinatal deaths in foetuses without anomalies. Aims The aim of this study was to evaluate the importance of cervical length measured in the first trimester (11–14 Weeks of amenorrhea “WA” and the second trimester (20–24 Weeks of amenorrhea” WA” in an asymptomatic population of singleton pregnancies to assess the risk of spontaneous preterm birth compared to the digital assessment. Methods We conducted a prospective, longitudinal study involving 117 asymptomatic women with singleton pregnancies between January and December 2015. Results In our study, the clinical examination had a low positive predictive value and a low sensibility for screening women at risk of preterm delivery. Cervical length less than 35mm between 12–14WA and 30mm between 22–24WA predicts the occurrence of preterm birth with a high sensitivity (Se, and specificity (Sp. Conclusion We conclude that ultrasound screening of preterm delivery is now highly recommended.

Prematurity is a public health problem that calls to focus on its causes and consequences through a trans disciplinary approach. There are no studies analyzing premature birth from the perspective of individuals born preterm. To identify social representations associated with premature birth of individuals born preterm in the 1990s in Argentina. Twelve focus groups were conducted with individuals born preterm with a birth weightparents' memories and experiences, overprotection body, education, relationship with the medical practice and knowledge. The methodology used allowed to create a space for mutual recognition and reflection for participants. Prematurity is a significant element, especially in those who suffered major sequelae. Adolescents and youth give a warning on the negative effects caused by overprotective parents and reveal the possibility of redefining the challenges associated with their history of premature birth.

Sphingosine Kinase: A Novel Putative Target for the Prevention of Infection-Triggered Preterm Birth

2013-01-01

Full Text Available Preterm birth is defined as any delivery before 37 complete weeks of gestation. It is a universal challenge in the field of obstetrics owing to its high rate of mortality, long-term morbidity, associated human suffering and economic burden. In the United States, about 12.18% deliveries in 2009 were preterm, producing an exorbitant cost of $5.8 billion. Infection-associated premature rupture of membranes (PROM accounts for 40% of extremely preterm births (<28 weeks of gestation. Major research efforts are directed towards improving the understanding of the pathophysiology of preterm birth and ways to prevent or at least postpone delivery. Endothelin-1 (ET-1 is a potent vasoconstrictor that plays a significant role in infection-triggered preterm birth. Its involvement in a number of pathological mechanisms and its elevation in preterm delivered amniotic fluid samples implicate it in preterm birth. Sphingosine kinase (SphK is a ubiquitous enzyme responsible for the production of sphingosine-1-phosphate (S1P. S1P acts as second messenger in a number of cell proliferation and survival pathways. SphK is found to play a key role in ET-1 mediated myometrial contraction. This review highlights SphK as a prospective target with great potential to prevent preterm birth.

Current intra-partum monitoring techniques are often criticized for their poor specificity, with their performance frequently evaluated using measures of the neonatal condition at birth as a surrogate marker for intra-partum fetal compromise. However, these measures may potentially be influenced by a multitude of other factors, including the mode of delivery itself. This study aimed to investigate the impact of mode of delivery on neonatal condition at birth. This prospective observational study, undertaken at a tertiary referral maternity unit in London, UK, included 604 'low risk' women recruited prior to delivery. Commonly assessed neonatal outcome variables (Apgar score at 1 and 5min, umbilical artery pH and base excess, neonatal unit admission, and a composite neonatal outcome score) were used to compare the condition at birth between babies born by different modes of delivery, using one-way ANOVA and chi-squared testing. Infants born by instrumental delivery for presumed fetal compromise had the poorest condition at birth (mean composite score=1.20), whereas those born by Cesarean section for presumed fetal compromise had a better condition at birth (mean composite score=0.64) (p=surrogate marker of intra-partum fetal compromise. When evaluating the efficacy of intra-partum monitoring techniques, the isolated use of Apgar scores, umbilical artery acidosis and neonatal unit admission should be discouraged.

Prenatal complications are associated with poor outcomes in the offspring. Access to medical records is limited in the United States and investigators often rely on maternal report of prenatal complications. We tested concordance between maternal recall and birth records in a community-based sample of mothers participating in a longitudinal study in order to determine the accuracy of maternal recall of perinatal complications. Participants were 151 biological mothers, who were interviewed about gestational age at birth, birthweight, and the most commonly occurring birth complications: nuchal cord and meconium aspiration when the female child was on average 6years old, and for whom birth records were obtained. Concordance between reports was assessed using one-way random intra-class coefficients for continuous measures and kappa coefficients for dichotomous outcomes. Associations between maternal demographic and psychological factors and discrepancies also were tested. Concordance was excellent for continuously measured birthweight (ICC=0.85, pbirth record and absence according to maternal recall. Receipt of public assistance was associated with a decrease in discrepancy in report of nuchal cord. Concordance between maternal retrospective report and medical birth records varies across different types of perinatal events. There was little evidence that demographic or psychological factors increased the risk of discrepancies. Maternal recall based on continuous measures of perinatal factors may yield more valid data than dichotomous outcomes. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Birth year distribution in reported hepatitis C cases in Switzerland.

Bruggmann, Philip; Richard, Jean-Luc

2015-02-01

Data of the national hepatitis C virus (HCV) notification system and the Swiss hepatitis C cohort study have been analysed for birth year distribution. Persons born between 1955 and 1974 are disproportionally affected by HCV, accounting for 61% of all reported infections. Over the course of the reporting period from 1988 to 2012, the majority of affected persons were born in the mid-60s and a sharply increasing proportion between 1975 and 1984 (from 0.6 to 19.5%). To enhance the so far insufficient HCV detection rates in Switzerland, additional testing strategies such as birth cohort screening must be further evaluated and discussed. © The Author 2014.

Preterm birth, an unresolved issue.

Science.gov (United States)

Belizán, Jose M; Hofmeyr, Justus; Buekens, Pierre; Salaria, Natasha

2013-11-15

Premature birth is the world's leading cause of neonatal mortality with worldwide estimates indicating 11.1% of all live births were preterm in 2010. Preterm birth rates are increasing in most countries with continual differences in survival rates amongst rich and poor countries. Preterm birth is currently an important unresolved global issue with research efforts focusing on uterine quiescence and activation, the 'omics' approaches and implementation science in order to reduce the incidence and increase survival rates of preterm babies. The journal Reproductive Health has published a supplement entitled Born Too Soon which addresses factors in the preconception and pregnancy period which may increase the risk of preterm birth and also outlines potential interventions which may reduce preterm birth rates and improve survival of preterm babies by as much as 84% annually. This is critical in order to achieve the Millennium Development Goal (MDG 4) for child survival by 2015 and beyond.

Maternal asthma, diabetes, and high blood pressure are associated with low birth weight and increased hospital birth and delivery charges; Hawai'i hospital discharge data 2003-2008.

Asthma, diabetes, and high blood pressure are common maternal conditions that can impact birth outcomes. Data from hospital discharges in Hawai'i were analyzed for 107,034 singleton births from 2003-2008. Categories were determined using the International Statistical Classification of Diseases, ninth revision (ICD-9) from linked delivery records of mother and infant. Prevalence estimates of asthma (ICD-9: 493), diabetes (ICD-9: 250,648.0, 648.8), high blood pressure (ICD-9: 401-405,642) as coded on the delivery record, low birth weight (4500 grams), Cesarean delivery, and median hospital charges were calculated. Median regression analysis assessed total hospital charges adjusting for maternal age, maternal race, insurance, and Cesarean delivery. Maternal asthma was present in 4.3% (95% confidence interval=4.1-4.4%), maternal diabetes was present in 7.7% (95% CI=7.6-7.9%), and maternal high blood pressure was present in 9.2% (95% CI=9.0-9.3%) of births. In the adjusted median regression analysis, mothers with asthma had $999 (95% CI: $886 to $1,112) higher hospital charges compared to those without; mothers with diabetes had $743 (95% CI: $636 to $850) higher charges compared to those without; and mothers with high blood pressure had $2,314 (95% CI: $2,194 to $2,434) higher charges compared to those without. Asthma, diabetes, and high blood pressure are associated with higher hospital delivery charges and low birth weight. Diabetes and high blood pressure were also associated with Cesarean delivery. An increased awareness of the impact of these conditions on both adverse birth outcomes and the development of chronic disease is needed.

The birth and survival of wildebeest calves.

Science.gov (United States)

Estes, R D; Estes, R K

1979-05-01

This paper describes social organization, parturition, post partum behavior of wildebeest mothers and offspring, and calf predation during the annual birth peak in Ngorongoro Crater, Tanzania. The wildebeest's "follower-calf" system, unique among the Bovidae, is remarkably effective in protecting neonates. Even during hte one-month peak, the major predator on calves, the spotted hyena, is unable to feed to satiation. Calf survival is consistently high, despite large fluctuations in the numbers of wildebeest, with consequent effects on the size of the yearly calf crop.

Many studies have investigated the possible association between birth order and risk of childhood cancer, although the evidence to date has been inconsistent. Birth order has been used as a marker for various in utero or childhood exposures and is relatively straightforward to assess. Data were obtained on all children born in Denmark between 1973 and 2010, involving almost 2.5 million births and about 5,700 newly diagnosed childhood cancers before the age of 20 years. Data were analyzed using Poisson regression models. We failed to observe associations between birth order and risk of any childhood cancer subtype, including acute lymphoblastic leukemia; all rate ratios were close to one. Further analyses stratified by birth cohort (those born between 1973 and 1990, and those born between 1991 and 2010) also failed to show any associations. Considering stillbirths and/or controlling for birth weight and parental age in the analyses had no effect on the results. Analyses by years of birth (those born between 1973 and 1990, and those born between 1991 and 2010) did not show any changes in the overall pattern of no association. In this large cohort of all children born in Denmark over an almost 40-year period, we did not observe an association between birth order and the risk of childhood cancer.

To analyze economic inequality (absolute and relative) due to family income in relation to the occurrence of preterm births in Southern Brazil. Four birth cohort studies were conducted in the years 1982, 1993, 2004, and 2011. The main exposure was monthly family income and the primary outcome was preterm birth. The inequalities were calculated using the slope index of inequality and the relative index of inequality, adjusted for maternal skin color, education, age, and marital status. The prevalence of preterm births increased from 5.8% to approximately 14% (p-trendinequality demonstrated that income inequality arose in the 1993, 2004, and 2011 studies. After adjustment, only the 2004 study maintained the difference between the poorest and the richest subjects, which was 6.3 percentage points. The relative index of inequality showed that, in all studies, the poorest mothers were more likely to have preterm newborns than the richest. After adjustment for confounding factors, it was observed that the poorest mothers only had a greater chance of this outcome in 2004. In a final model, economic inequalities resulting from income were found in relation to preterm births only in 2004, although a higher prevalence of prematurity continued to be observed in the poorest population, in all the studies.

Ethics and "normal birth".

Science.gov (United States)

Lyerly, Anne Drapkin

2012-12-01

The concept of "normal birth" has been promoted as ideal by several international organizations, although debate about its meaning is ongoing. In this article, I examine the concept of normalcy to explore its ethical implications and raise a trio of concerns. First, in its emphasis on nonuse of technology as a goal, the concept of normalcy may marginalize women for whom medical intervention is necessary or beneficial. Second, in its emphasis on birth as a socially meaningful event, the mantra of normalcy may unintentionally avert attention to meaning in medically complicated births. Third, the emphasis on birth as a normal and healthy event may be a contributor to the long-standing tolerance for the dearth of evidence guiding the treatment of illness during pregnancy and the failure to responsibly and productively engage pregnant women in health research. Given these concerns, it is worth debating not just what "normal birth" means, but whether the term as an ideal earns its keep. © 2012, Copyright the Authors Journal compilation © 2012, Wiley Periodicals, Inc.

Live-Birth Rate Associated With Repeat In Vitro Fertilization Treatment Cycles.

Smith, Andrew D A C; Tilling, Kate; Nelson, Scott M; Lawlor, Debbie A

The likelihood of achieving a live birth with repeat in vitro fertilization (IVF) is unclear, yet treatment is commonly limited to 3 or 4 embryo transfers. To determine the live-birth rate per initiated ovarian stimulation IVF cycle and with repeated cycles. Prospective study of 156,947 UK women who received 257,398 IVF ovarian stimulation cycles between 2003 and 2010 and were followed up until June 2012. In vitro fertilization, with a cycle defined as an episode of ovarian stimulation and all subsequent separate fresh and frozen embryo transfers. Live-birth rate per IVF cycle and the cumulative live-birth rates across all cycles in all women and by age and treatment type. Optimal, prognosis-adjusted, and conservative cumulative live-birth rates were estimated, reflecting 0%, 30%, and 100%, respectively, of women who discontinued due to poor prognosis and having a live-birth rate of 0 had they continued. Among the 156,947 women, the median age at start of treatment was 35 years (interquartile range, 32-38; range, 18-55), and the median duration of infertility for all 257,398 cycles was 4 years (interquartile range, 2-6; range, cycle was 29.5% (95% CI, 29.3%-29.7%). This remained above 20% up to and including the fourth cycle. The cumulative prognosis-adjusted live-birth rate across all cycles continued to increase up to the ninth cycle, with 65.3% (95% CI, 64.8%-65.8%) of women achieving a live birth by the sixth cycle. In women younger than 40 years using their own oocytes, the live-birth rate for the first cycle was 32.3% (95% CI, 32.0%-32.5%) and remained above 20% up to and including the fourth cycle. Six cycles achieved a cumulative prognosis-adjusted live-birth rate of 68.4% (95% CI, 67.8%-68.9%). For women aged 40 to 42 years, the live-birth rate for the first cycle was 12.3% (95% CI, 11.8%-12.8%), with 6 cycles achieving a cumulative prognosis-adjusted live-birth rate of 31.5% (95% CI, 29.7%-33.3%). For women older than 42 years, all rates within each cycle

Prospective study of determinants and costs of home births in Mumbai slums

Full Text Available Abstract Background Around 86% of births in Mumbai, India, occur in healthcare institutions, but this aggregate figure hides substantial variation and little is known about urban home births. We aimed to explore factors influencing the choice of home delivery, care practices and costs, and to identify characteristics of women, households and the environment which might increase the likelihood of home birth. Methods As part of the City Initiative for Newborn Health, we used a key informant surveillance system to identify births prospectively in 48 slum communities in six wards of Mumbai, covering a population of 280 000. Births and outcomes were documented prospectively by local women and mothers were interviewed in detail at six weeks after delivery. We examined the prevalence of home births and their associations with potential determinants using regression models. Results We described 1708 (16% home deliveries among 10 754 births over two years, 2005-2007. The proportion varied from 6% to 24%, depending on area. The most commonly cited reasons for home birth were custom and lack of time to reach a healthcare facility during labour. Seventy percent of home deliveries were assisted by a traditional birth attendant (dai, and 6% by skilled health personnel. The median cost of a home delivery was US$ 21, of institutional delivery in the public sector US$ 32, and in the private sector US$ 118. In an adjusted multivariable regression model, the odds of home delivery increased with illiteracy, parity, socioeconomic poverty, poorer housing, lack of water supply, population transience, and hazardous location. Conclusions We estimate 32 000 annual home births to residents of Mumbai's slums. These are unevenly distributed and cluster with other markers of vulnerability. Since cost does not appear to be a dominant disincentive to institutional delivery, efforts are needed to improve the client experience at public sector institutions. It might also be

Risk factors and birth outcomes of anaemia in early pregnancy in a nulliparous cohort.

Directory of Open Access Journals (Sweden)

Gwinyai Masukume

Full Text Available Anaemia in pregnancy is a major public health and economic problem worldwide, that contributes to both maternal and fetal morbidity and mortality.The aim of the study was to calculate the prevalence of anaemia in early pregnancy in a cohort of 'low risk' women participating in a large international multicentre prospective study (n = 5 609, to identify the modifiable risk factors for anaemia in pregnancy in this cohort, and to compare the birth outcomes between pregnancies with and without anaemia in early gestation.The study is an analysis of data that were collected prospectively during the Screening for Pregnancy Endpoints study. Anaemia was defined according to the World Health Organization's definition of anaemia in pregnancy (haemoglobin < 11g/dL. Binary logistic regression with adjustment for potential confounders (country, maternal age, having a marital partner, ethnic origin, years of schooling, and having paid work was the main method of analysis.The hallmark findings were the low prevalence of anaemia (2.2%, that having no marital partner was an independent risk factor for having anaemia (OR 1.34, 95% CI 1.01-1.78, and that there was no statistically significant effect of anaemia on adverse pregnancy outcomes (small for gestational age, pre-tem birth, mode of delivery, low birth weight, APGAR score < 7 at one and five minutes. Adverse pregnancy outcomes were however more common in those with anaemia than in those without.In this low risk healthy pregnant population we found a low anaemia rate. The absence of a marital partner was a non-modifiable factor, albeit one which may reflect a variety of confounding factors, that should be considered for addition to anaemia's conceptual framework of determinants. Although not statistically significant, clinically, a trend towards a higher risk of adverse pregnancy outcomes was observed in women that were anaemic in early pregnancy.

Bias from conditioning on live birth in pregnancy cohorts: an illustration based on neurodevelopment in children after prenatal exposure to organic pollutants

Only 60–70% of fertilized eggs may result in a live birth, and very early fetal loss mainly goes unnoticed. Outcomes that can only be ascertained in live-born children will be missing for those who do not survive till birth. In this article, we illustrate a common bias structure (leading to ‘live-birth bias’) that arises from studying the effects of prenatal exposure to environmental factors on long-term health outcomes among live births only in pregnancy cohorts. To illustrate this we used prenatal exposure to perfluoroalkyl substances (PFAS) and attention-deficit/hyperactivity disorder (ADHD) in school-aged children as an example. PFAS are persistent organic pollutants that may impact human fecundity and be toxic for neurodevelopment. We simulated several hypothetical scenarios based on characteristics from the Danish National Birth Cohort and found that a weak inverse association may appear even if PFAS do not cause ADHD but have a considerable effect on fetal survival. The magnitude of the negative bias was generally small, and adjusting for common causes of the outcome and fetal loss can reduce the bias. Our example highlights the need to identify the determinants of pregnancy loss and the importance of quantifying bias arising from conditioning on live birth in observational studies. PMID:25604449

Birth size is an important gauge of fetal and neonatal health. Birth size measurements were collected within 72 h of life for 16 290 live born, singleton infants in rural Bangladesh from 2004 to 2007. Gestational age was calculated based on the date of last menstrual period. Newborns were classified as small-for-gestational age (SGA) based on a birthweight below the 10th percentile for gestational age, using three sets of US reference data. Birth size distributions were explored based on raw values as well as after z-score standardisation in reference to World Health Organization (WHO) 2006 growth standards. Mean (SD) birthweight (g), length (cm) and head circumference (cm) measurements, completed within [median (25th, 75th percentile)] 15 (8, 23) h of life, were 2433 (425), 46.4 (2.4) and 32.4 (1.6), respectively. Twenty-two per cent were born preterm. Over one-half (55.3%) of infants were born low birthweight; 46.6%, 37.0% and 33.6% had a weight, length and head circumference below -2 z-scores of the WHO growth standard at birth; and 70.9%, 72.2% and 59.8% were SGA for weight based on Alexander et al., Oken et al. and Olsen et al. references, respectively. Infants in this typical rural Bangladesh setting were commonly born small, reflecting a high burden of fetal growth restriction and preterm birth. Our findings, produced by active birth surveillance, suggest that low birthweight is far more common than suggested by cross-sectional survey estimates. Interventions that improve fetal growth during pregnancy may have the largest impact on reducing SGA rates. © 2013 John Wiley & Sons Ltd.

Official data on sex ratios at birth suggest a rise in sex-selective abortions in some post-Soviet states following the introduction of ultrasonography. However, questions remain about the validity of official data in these nations as well as whether the high sex ratios at birth are a statistical artifact. Trends in sex ratios at birth from 1985 to 2009 for 12 post-Soviet states were examined using vital registration data. For the three countries that had had a Demographic and Health Survey (DHS) in 2005-2010 (Armenia, Azerbaijan and Moldova), survey data were used to calculate sex ratios at birth according to birth order, and vital registration data for 2010 were used to estimate the number of "missing" female births (if any). Official data revealed elevated sex ratios at birth in Armenia (117), Azerbaijan (116) and Georgia (121), but not in other post-Soviet states. According to DHS data, sex ratios were high in Armenia and Azerbaijan for first births (138 and 113, respectively); if the first child was a girl, the sex ratio in Armenia was even higher for the second birth (154). Overall, the number of girls born in these countries in 2010 was 10% lower than expected, consistent with 1,972 sex-selective abortions in Armenia and 8,381 in Azerbaijan. Sex ratios did not vary by birth order in Moldova. Sex-selective abortion appears to be common in Azerbaijan and Armenia. Family planning and legal interventions are needed to address this issue.

Effects on metabolic parameters in young rats born with low birth weight after exposure to a mixture of pesticides

DEFF Research Database (Denmark)

Svingen, Terje; Ramhøj, Louise; Egebjerg, Karen Mandrup

2018-01-01

Pesticide exposure during fetal life can lead to low birth weight and is commonly observed in reproductive toxicology studies. Associations have also been found in low birth weight babies born from pesticide-exposed gardeners. Since low birth weight is also linked to metabolic disorders, it can...... be speculated that early life exposure to pesticides could increase the risk of becoming obese or developing diabetes later in life. We have analyzed potential long-term effects of gestational and lactational exposure to a low dose mixture of six pesticides that individually can cause low birth weight....... Our results suggest that early-life exposure to pesticides may contribute to the development of metabolic disorders later in life....

Effects of Maternal Age and Age-Specific Preterm Birth Rates on Overall Preterm Birth Rates - United States, 2007 and 2014.

Reductions in births to teens and preterm birth rates are two recent public health successes in the United States (1,2). From 2007 to 2014, the birth rate for females aged 15-19 years declined 42%, from 41.5 to 24.2 per 1,000 females. The preterm birth rate decreased 8.4%, from 10.41% to 9.54% of live births (1). Rates of preterm births vary by maternal age, being higher among the youngest and oldest mothers. It is unknown how changes in the maternal age distribution in the United States have affected preterm birth rates. CDC used birth data to assess the relative contributions of changes in the maternal age distribution and in age-specific preterm birth rates to the overall decrease in preterm birth rates. The preterm birth rate declined in all age groups. The effects of age distribution changes on the preterm birth rate decrease were different in younger and older mothers. The decrease in the proportion of births to mothers aged ≤19 and 20-24 years and reductions in age-specific preterm rates in all age groups contributed to the overall decline in the preterm birth rate. The increase in births to mothers aged ≥30 years had no effect on the overall preterm birth rate decrease. The decline in preterm births from 2007 to 2014 is related, in part, to teen pregnancy prevention and the changing maternal age distribution. Effective public health strategies for further reducing preterm birth rates need to be tailored to different age groups.

Complete text of publication follows. Objective: In a report published in JAMA in 2004, Hujoel and colleagues indicated that maternal dental radiography during pregnancy may be associated with term low birth weight. Interestingly, they concluded that dental radiographies cause measurable radiation doses to the hypothalamus-pituitary-thyroid axis and the radiation effects on this axis is the reason for term low birth weight. On the other hand, low birth weight is the second leading cause of infant death. In this paper the results obtained in a 2 year study conducted at a midwifery hospital in Rafsanjan, IR Iran are reported. Methods: Four hundred seventy-five singleton infants with gestational periods of 37-44 wk born between 2006 and 2007 at the Niknafs Teaching Hospital affiliated with Rafsanjan University of Medical Sciences and met the inclusion criteria were enrolled in the study. Demographic data and clinical findings at birth including gestation age, sex of infant, birth order, season of birth, maternal age, and maternal education were collected from maternal and newborn hospital records and by interviews with parents. Maternal history of exposure to common sources of man-made ionizing and non-ionizing (exposure to radiations emitted by mobile phones, CRTs, cordless phones) radiation before and during pregnancy were carefully recorded. Results: Among the 475 infants who were studied, there were only 15 cases with a history of maternal dental radiography during pregnancy. The average newborn infants' birth weight in non-exposed and exposed (maternal dental radiography during pregnancy) groups were 3166.69±481.31 g and 3118.67±341.42 g respectively. This difference was not statistically significant. Conclusions: In this study, low birth weight was not associated with maternal dental radiography during pregnancy. These results are generally inconsistent with those reported by Hujoel and colleagues.

Socioeconomic inequalities in very preterm birth rates.

To investigate the extent of socioeconomic inequalities in the incidence of very preterm birth over the past decade. Ecological study of all 549 618 births in the former Trent health region, UK, from 1 January 1994 to 31 December 2003. All singleton births of 22(+0) to 32(+6) weeks gestation (7 185 births) were identified from population surveys of neonatal services and stillbirths. Poisson regression was used to calculate incidence of very preterm birth (22-32 weeks) and extremely preterm birth (22-28 weeks) by year of birth and decile of deprivation (child poverty section of the Index of Multiple Deprivation). Incidence of very preterm singleton birth rose from 11.9 per 1000 births in 1994 to 13.7 per 1000 births in 2003. Those from the most deprived decile were at nearly twice the risk of very preterm birth compared with those from the least deprived decile, with 16.4 per 1000 births in the most deprived decile compared with 8.5 per 1000 births in the least deprived decile (incidence rate ratio 1.94; 95% CI (1.73 to 2.17)). This deprivation gap remained unchanged throughout the 10-year period. The magnitude of socio-economic inequalities was the same for extremely preterm births (22-28 weeks incidence rate ratio 1.94; 95% CI (1.62 to 2.32)). This large, unique dataset of very preterm births shows wide socio-economic inequalities that persist over time. These findings are likely to have consequences on the burden of long-term morbidity. Our research can assist future healthcare planning, the monitoring of socio-economic inequalities and the targeting of interventions in order to reduce this persistent deprivation gap.

Full Text Available Abstract Background Malaria is more common in pregnant than in non-pregnant Nigerian women, and is associated with small birth size and the attendant short- and long-term health risks. The influence of malaria on maternal metabolic status in pregnancy and in cord blood and how this relates to birth size has not been studied. The study objective was to define relationships between maternal and cord serum metabolic markers, maternal malaria status and birth size. Methods During pregnancy, anthropometric measurements, blood film for malaria parasites and assays for lipids, glucose, insulin and TNF were obtained from 467 mothers and these analytes and insulin-like growth factor-I (IGF-I were obtained from cord blood of 187 babies. Results Overall prevalence of maternal malaria was 52%, associated with younger age, anaemia and smaller infant birth size. Mothers with malaria had significantly lower cholesterol (total, HDL and LDL and higher TNF, but no difference in triglyceride. In contrast, there was no effect of maternal malaria on cord blood lipids, but the median (range cord IGF-I was significantly lower in babies whose mothers had malaria: 60.4 (24,145μg/L, versus no malaria: 76.5 (24, 150μg/L, p = 0.03. On regression analysis, the key determinants of birth weight included maternal total cholesterol, malarial status and cord insulin and IGF-I. Conclusions Malaria in pregnancy was common and associated with reduced birth size, lower maternal lipids and higher TNF. In the setting of endemic malaria, maternal total cholesterol during pregnancy and cord blood insulin and IGF-I levels are potential biomarkers of foetal growth and birth size.

INTRODUCTION: The safety of home births has been widely debated. Observational studies examining maternal and neonatal outcomes of home births have become more frequent, and the quality of these studies has improved. The aim of the present study was to describe neonatal outcomes of home births...... compared with hospital births and to discuss which data are needed to evaluate the safety of home births. METHODS: This was a register-based cohort study. Data on all births in Denmark (2003-2013) were collected from the Danish Medical Birth Registry (DMBR). The cohort included healthy women...... with uncomplicated pregnancies and no medical interventions during delivery. A total of 6,395 home births and 266,604 hospital births were eligible for analysis. Comparative analyses were performed separately in nulliparous and multiparous women. The outcome measures were neonatal mortality and morbidity. RESULTS...

Extra-uterine growth retardation (EUGR) is associated with an increased risk for cardiometabolic diseases later in life. The aim of the present study was to examine the relationship between early weight change after birth in preterm infants and adiponectin (adn) multimeric complexes. Subjects included 28 preterm infants born between weeks 24 and 33 of gestation. Serum adn multimeric complexes and the anthropometric parameters were measured in preterm infants at birth and at corrected term. Bodyweight (BW) decreased during the first week of life, with birthweight restored at approximately 19 days after birth. Nineteen of the subjects had EUGR at corrected term. Total (T)-adn, high-molecular-weight (H)-adn, and the ratio of H-adn to T-adn (H/T-adn) were significantly elevated at corrected term than at birth. Postmenstrual age, birthweight, birth length and lowest BW after birth were positively correlated with H-adn and H/T-adn. Weight reduction after birth was negatively correlated with H-adn. Age to restore birthweight was negatively correlated with T-adn, H-adn and H/T-adn. Stepwise multiple regression analysis indicated age to restore birthweight as the major predictor of T-adn and H-adn. Early weight changes after birth may alter serum adn level in preterm infants at corrected term. The appropriate nutritional support in the early postnatal period could reduce the prevalence of EUGR and the future risk for cardiometabolic diseases. © 2011 The Authors.

Relationships between prenatal exposure to fine particles (PM 2.5 ) and birth weight have been observed previously. Few studies have investigated specific constituents of PM 2.5 , which may identify sources and major contributors of risk. We examined the effects of trimester and full gestational prenatal exposures to PM 2.5 mass and 23 PM 2.5 constituents on birth weight among 646,296 term births in California between 2000 and 2006. We used linear and logistic regression models to assess associations between exposures and birth weight and risk of low birth weight (LBW; 2.5 mass and several PM 2.5 constituents were significantly associated with reductions in term birth weight. The largest reductions in birth weight were associated with exposure to vanadium, sulfur, sulfate, iron, elemental carbon, titanium, manganese, bromine, ammonium, zinc, and copper. Several of these PM 2.5 constituents were associated with increased risk of term LBW. Reductions in birth weight were generally larger among younger mothers and varied by race/ethnicity. Exposure to specific constituents of PM 2.5 , especially traffic-related particles, sulfur constituents, and metals, were associated with decreased birth weight in California. -- Highlights: • Examine full gestational and trimester fine particle and its constituents on term birth weight. • Fine particles and several of its constituents associated with birth weight reductions. • Largest reductions for traffic-related particles, sulfur constituents, and metals. • Greater birth weight reductions for younger mothers, and varied by race/ethnicity

Coping and help in birth: An investigation into 'normal' childbirth as described by new mothers and their attending midwives.

to investigate how 'normal' childbirth is described by new mothers and their attending midwives. a qualitative, reflexive, narrative study was used to explore birth stories using in-depth, un-structured interviews. 21 new mothers and their 16 attending midwives were recruited from the locality surrounding a district general hospital in South Wales, United Kingdom (UK). the findings identified that the mothers wanted to cope with labour and birth, by breathing through it and using some birth interventions with the help of knowledgeable midwives. Midwives aimed to achieve 'normality' in birth but also commonly utilised birth interventions. Consequently the notion of 'normal' birth as not involving interventions in birth was not found to be a useful defining concept in this study. Furthermore, current dichotomous models and theories of birth and midwifery in particular those relating to pain management did not fully explain the perspectives of these women and their midwives. dichotomous models and theories for birth and midwifery practice and those which incorporate the term 'normal' birth are shown to be not entirely useful to fully explain the contemporary complexity of childbirth in the UK. Therefore it is now necessary to consider avoiding using dichotomous models of birth and midwifery in the UK and to instead concentrate on developing integrated models that reflect the real life current experiences of women and their midwives.

The present article describes an experience with traditional birth attendants carried out in the state of Tocantins, Brazil, between 2010 and 2014. The experience was part of a diagnostic project to survey home deliveries in the state of Tocantins and set up a registry of traditional birth attendants for the Health Ministry's Working with Traditional Birth Attendants Program (PTPT). The project aimed to articulate the home deliveries performed by traditional birth attendants to the local health care systems (SUS). Sixty-seven active traditional birth attendants were identified in the state of Tocantins, and 41 (39 indigenous) participated in workshops. During these workshops, they discussed their realities, difficulties, and solutions in the context of daily adversities. Birth attendants were also trained in the use of biomedical tools and neonatal resuscitation. Based on these experiences, the question came up regarding the true effectiveness of the strategy to include traditional birth attendants in the SUS. The present article discusses this theme with support from the relevant literature. The dearth of systematic studies focusing on the impact of PTPT actions on the routine of traditional birth attendants, including perinatal outcomes and remodeling of health practices in rural, riverfront, former slave, forest, and indigenous communities, translates into a major gap in terms of the knowledge regarding the effectiveness of such initiatives.

How Would Children Register Their Own Births? Insights from a Survey of Students Regarding Birth Registration Knowledge and Policy Suggestions in Kenya.

Directory of Open Access Journals (Sweden)

Matthew Pelowski

Full Text Available Birth registration and obtaining physical birth certificates impose major challenges in developing countries, with impact on child and community health, education, planning, and all levels of development. However despite initiatives, universal registration is elusive, leading to calls for new approaches to understanding the decisions of parents. In this paper, we report results of a survey of students in grades six to eight (age ~12-16 in an under-registered area of Kenya regarding their own understanding of registration issues and their suggestions for improvement. These students were selected because they themselves were also nearing the age for high school enrollment/entrance examinations, which specifically requires possession of a birth certificate. This assessment was also a companion to our previous representative survey of adults in the same Kenyan region, allowing for parent-child comparison. Results supported previous research, showing that only 43% had birth certificates. At the same time, despite these low totals, students were themselves quite aware of registration factors and purposes. The students also made quite prescient sources for understanding their households' motivations, with many of their suggestions-for focus on communication of pragmatic benefits, or automatic measures shifting responsibility from parents-mirroring our own previous suggestions, and showing a level of pragmatism not witnessed when surveying their parents. This paper therefore adds evidence to the discussion of registration policy planning. More generally, it also builds on an important trend regarding the treatment of children as stakeholders and important sources of information, and raising an intriguing new avenue for future research.

Nasal birth trauma: a review of appropriate treatment.

LENUS (Irish Health Repository)

Cashman, E C

2012-02-01

The aetiology of nasal deformity has frequently included birth trauma. There is no consensus in the literature as to whether nasal surgery, in the form of closed reduction, is indicated in neonates. The majority of studies in the literature that advocate intervention have inadequate followup periods and there is a paucity of evidence for the adverse effects of conservative management. This case highlights the therapeutic dilemma posed by such nasal injuries in the neonate and, to the best of the authors\\' knowledge, at the time of writing, represents the earliest reported case in the literature of nasal deformity in the neonate. The term nasal deformity is used to denote deformity of the nasal pyramid, soft tissue, and septum. Three main aspects of neonatal nasal deformity are addressed including, firstly, if nasal deformity at birth needs to be addressed, secondly, if left unaltered, what the long-term effects are and, finally, if intervention alters the normal course of midfacial development.

Maternal Asthma, Diabetes, and High Blood Pressure are Associated with Low Birth Weight and Increased Hospital Birth and Delivery Charges; Hawai‘i Hospital Discharge Data 2003–2008

Feigal, David W; Smith, Ruben A; Fuddy, Loretta J

2014-01-01

Asthma, diabetes, and high blood pressure are common maternal conditions that can impact birth outcomes. Data from hospital discharges in Hawai‘i were analyzed for 107,034 singleton births from 2003–2008. Categories were determined using the International Statistical Classification of Diseases, ninth revision (ICD-9) from linked delivery records of mother and infant. Prevalence estimates of asthma (ICD-9: 493), diabetes (ICD-9: 250,648.0, 648.8), high blood pressure (ICD-9: 401–405,642) as coded on the delivery record, low birth weight (4500 grams), Cesarean delivery, and median hospital charges were calculated. Median regression analysis assessed total hospital charges adjusting for maternal age, maternal race, insurance, and Cesarean delivery. Maternal asthma was present in 4.3% (95% confidence interval=4.1–4.4%), maternal diabetes was present in 7.7% (95% CI=7.6–7.9%), and maternal high blood pressure was present in 9.2% (95% CI=9.0–9.3%) of births. In the adjusted median regression analysis, mothers with asthma had $999 (95% CI: $886 to $1,112) higher hospital charges compared to those without; mothers with diabetes had $743 (95% CI: $636 to $850) higher charges compared to those without; and mothers with high blood pressure had $2,314 (95% CI: $2,194 to $2,434) higher charges compared to those without. Asthma, diabetes, and high blood pressure are associated with higher hospital delivery charges and low birth weight. Diabetes and high blood pressure were also associated with Cesarean delivery. An increased awareness of the impact of these conditions on both adverse birth outcomes and the development of chronic disease is needed. PMID:24567868

Environmental exposure assessment in European birth cohorts: results from the ENRIECO project

2013-01-01

Full Text Available Abstract Environmental exposures during pregnancy and early life may have adverse health effects. Single birth cohort studies often lack statistical power to tease out such effects reliably. To improve the use of existing data and to facilitate collaboration among these studies, an inventory of the environmental exposure and health data in these studies was made as part of the ENRIECO (Environmental Health Risks in European Birth Cohorts project. The focus with regard to exposure was on outdoor air pollution, water contamination, allergens and biological organisms, metals, pesticides, smoking and second hand tobacco smoke (SHS, persistent organic pollutants (POPs, noise, radiation, and occupational exposures. The review lists methods and data on environmental exposures in 37 European birth cohort studies. Most data is currently available for smoking and SHS (N=37 cohorts, occupational exposures (N=33, outdoor air pollution, and allergens and microbial agents (N=27. Exposure modeling is increasingly used for long-term air pollution exposure assessment; biomonitoring is used for assessment of exposure to metals, POPs and other chemicals; and environmental monitoring for house dust mite exposure assessment. Collaborative analyses with data from several birth cohorts have already been performed successfully for outdoor air pollution, water contamination, allergens, biological contaminants, molds, POPs and SHS. Key success factors for collaborative analyses are common definitions of main exposure and health variables. Our review emphasizes that such common definitions need ideally be arrived at in the study design phase. However, careful comparison of methods used in existing studies also offers excellent opportunities for collaborative analyses. Investigators can use this review to evaluate the potential for future collaborative analyses with respect to data availability and methods used in the different cohorts and to identify potential partners

CALF CIRCUMFERENCE AT BIRTH: A SCREENING METHOD FOR DETECTION OF LOW BIRTH WEIGHT

Directory of Open Access Journals (Sweden)

Sandip Kumar

2012-12-01

Full Text Available Background: Low Birth Weight (LBW babies run a higher risk of morbidity and mortality in the perinatal period. However, in our country where almost 70-80% births take place at home and peripheral hospitals, taking accurate weight is a problem due to unavailability of weighing scale and trained personnel. Hence there is a constant search for newer methods to detect LBW babies so that early interventions can be instituted. Various authors have used different surrogate anthropometric measurements from different parts of our country. In the present study, an attempt was made to validate the feasibility of using calf circumference as a predictor of LBW babies that can be used by a trained or untrained person. Objectives: To study various anthropometric measurements including calf circumference in newborns and to correlate various measurements with birth weight. Methods: The present study was conducted in the department of Social & Preventive Medicine, MLB Medical College, Jhansi (UP for a period of one year. The study included 1100 consecutively delivered neonates in the maternity ward of MLB Medical College Hospital, Jhansi (UP. The birth weight (Wt, crown heel length (CHL, crown rump length (CRL, head circumference (HC, chest circumference (CC, mid arm circumference (MAC, thigh circumference (TC and calf circumference (CC by standard techniques. All the measurements were taken by a single person throughout the study period with in 24 hours of delivery. Standard statistical methods were adopted for determination of critical limit, sensitivity, specificity and correlation coefficient of different anthropometric measurements in relation to birth weight. Results: Analysis of data indicates that out of 1100 newborns, 55.64% were low birth weight. The percentage of newborns > 2500gm was 44.36. Overall average birth weight was 2348 ± 505gm. Out of 1100 newborns, 608 (55.27% were males and 492 (44.73% were females. Average birth weight for males was 2412

Social causes of low birth weight.

1995-01-01

The manifest importance of reducing the incidence of low birth weight is most obvious for the first year of life: low birth weight is the single most important factor affecting infant morbidity and mortality. However, there is growing evidence that the adverse consequences of low birth weight continue throughout the life cycle. This review deals primarily with social causes of low birth weight.

Neonatal Mortality of Planned Home Birth in the United States in Relation to Professional Certification of Birth Attendants.

Full Text Available Over the last decade, planned home births in the United States (US have increased, and have been associated with increased neonatal mortality and other morbidities. In a previous study we reported that neonatal mortality is increased in planned home births but we did not perform an analysis for the presence of professional certification status.The objective of this study therefore was to undertake an analysis to determine whether the professional certification status of midwives or the home birth setting are more closely associated with the increased neonatal mortality of planned midwife-attended home births in the United States.This study is a secondary analysis of our prior study. The 2006-2009 period linked birth/infant deaths data set was analyzed to examine total neonatal deaths (deaths less than 28 days of life in term singleton births (37+ weeks and newborn weight ≥ 2,500 grams without documented congenital malformations by certification status of the midwife: certified nurse midwives (CNM, nurse midwives certified by the American Midwifery Certification Board, and "other" or uncertified midwives who are not certified by the American Midwifery Certification Board.Neonatal mortality rates in hospital births attended by certified midwives were significantly lower (3.2/10,000, RR 0.33 95% CI 0.21-0.53 than home births attended by certified midwives (NNM: 10.0/10,000; RR 1 and uncertified midwives (13.7/10,000; RR 1.41 [95% CI, 0.83-2.38]. The difference in neonatal mortality between certified and uncertified midwives at home births did not reach statistical levels (10.0/10,000 births versus 13.7/10,000 births p = 0.2.This study confirms that when compared to midwife-attended hospital births, neonatal mortality rates at home births are significantly increased. While NNM was increased in planned homebirths attended by uncertified midwives when compared to certified midwives, this difference was not statistically significant. Neonatal

women who birth in private facilities in Australia are more likely to have a caesarean birth than women who birth in public facilities and these differences remain after accounting for sector differences in the demographic and health risk profiles of women. However, the extent to which women's preferences and/or freedom to choose their mode of birth further account for differences in the likelihood of caesarean birth between the sectors remains untested. women who birthed in Queensland, Australia during a two-week period in 2009 were mailed a self-report survey approximately 3 months after birth. Seven hundred and fifty-seven women provided cross-sectional retrospective data on where they birthed (public or private facility), mode of birth (vaginal or caesarean) and risk factors, along with their preferences and freedom to choose their mode of birth. A hierarchical logistic regression was conducted to determine the extent to which maternal risk and freedom to choose one's mode of birth explain sector differences in the likelihood of having a caesarean birth. while there was no sector difference in women's preference for mode of birth, women who birthed in private facilities had higher odds of feeling able to choose either a vaginal or caesarean birth, and feeling able to choose only a caesarean birth. Women had higher odds of having caesarean birth if they birthed in private facilities, even after accounting for significant risk factors such as age, body mass index, previous caesarean and use of assisted reproductive technology. However, there was no association between place of birth and odds of having a caesarean birth after also accounting for freedom to choose one's mode of birth. these findings call into question suggestions that the higher caesarean birth rate in the private sector in Australia is attributable to increased levels of obstetric risk among women birthing in the private sector or maternal preferences alone. Instead, the determinants of sector

Background There is increasing evidence of the role of arsenic in the etiology of adverse human reproductive outcomes. Since drinking water can be a major source of arsenic to pregnant women, the effect of arsenic exposure through drinking water on human birth may be revealed by a geospatial association between arsenic concentration in groundwater and birth problems, particularly in a region where private wells substantially account for water supply, like New Hampshire, US. Methods We calculated town-level rates of preterm birth and term low birth weight (term LBW) for New Hampshire, using data for 1997-2009 and stratified by maternal age. We smoothed the rates using a locally-weighted averaging method to increase the statistical stability. The town-level groundwater arsenic values are from three GIS data layers generated by the US Geological Survey: probability of local groundwater arsenic concentration > 1 μg/L, probability > 5 μg/L, and probability > 10 μg/L. We calculated Pearson's correlation coefficients (r) between the reproductive outcomes (preterm birth and term LBW) and the arsenic values, at both state and county levels. Results For preterm birth, younger mothers (maternal age arsenic level based on the data of probability > 10 μg/L; For older mothers, r = 0.19 when the smoothing threshold = 3,500; A majority of county level r values are positive based on the arsenic data of probability > 10 μg/L. For term LBW, younger mothers (maternal age arsenic level based on the data of probability > 1 μg/L; For older mothers, r = 0.14 when the rates are smoothed with a threshold = 1,000 births and also adjusted by town median household income in 1999, and the arsenic values are the town minimum based on probability > 10 μg/L. At the county level, for younger mothers positive r values prevail, but for older mothers it is a mix.

Full Text Available Background. Low birth weight is the single most important factor that determines the chances of child survival. A recent annual estimation indicated that nearly 8 million infants are born with low birth weight in India. The infant mortality rate is about 20 times greater for all low birth weight babies. Methods. A matched case–control study was conducted on 130 low birth weight babies and 130 controls for 12 months (from August 1, 2007, to July 31, 2008 at the Central Referral Hospital, Tadong, East District of Sikkim, India. Data were analyzed using the Statistical Package for Social Sciences, version 10.0 for Windows. Chi-square test and multiple logistic regression were applied. A P value less than .05 was considered as significant. Results. In the first phase of this study, 711 newborn babies, borne by 680 mothers, were screened at the Central Referral Hospital of Sikkim during the 1-year study period, and the proportion of low birth weight babies was determined to be 130 (18.3%. Conclusion. Multiple logistic regression analysis, conducted in the second phase, revealed that low or middle socioeconomic status, maternal underweight, twin pregnancy, previous history of delivery of low birth weight babies, smoking and consumption of alcohol during pregnancy, and congenital anomalies had independent significant association with low birth weight in this study population.

Reported birth prevalences of congenital limb defects (CLD) vary between countries: from 13/10,000 in Finland for the period 1964-1977 to 30.4/10,000 births in Scotland from 1964-1968. Epidemiological studies permit the timely detection of trends in CLD and of associations with other birth defects. The aim of this study is to describe the birth prevalence of CLD in the northern Netherlands. In a population-based, epidemiological study we investigated the birth prevalences of CLD for 1981-2010. Data were collected by the European Surveillance of Congenital Anomalies in the northern Netherlands (EUROCAT-NNL). We excluded malpositions, club foot, and dislocation/dysplasia of hips or knees. Trends were analysed for the 19-year period 1992-2010 using χ² tests, as well as CLD association with anomalies affecting other organs. The birth prevalence of CLD was 21.1/10,000 births for 1981-2010. There was an overall decrease in non-syndromic limb defects (P = 0.023) caused by a decrease in the prevalence of non-syndromic syndactyly (P CLD, 55% were males, 57% had isolated defects, 13% had multiple congenital anomalies (MCA), and 30% had a recognised syndrome. The upper:lower limb ratio was 2:1, and the left:right side ratio was 1.2:1. Cardiovascular and urinary tract anomalies were common in combination with CLD (37% and 25% of cases with MCA). Digestive-tract anomalies were significantly associated with CLD (P = 0.016). The birth prevalence of CLD in the northern Netherlands was 21.1/10,000 births. The birth prevalence of non-syndromic syndactyly dropped from 5.2/10,000 to 1.1/10,000 in 1992-2010.

This study investigates maternal and perinatal outcomes for women with low-risk pregnancies laboring in free-standing birth centers compared with laboring in a hospital maternity unit in a large New Zealand health district. The study used observational data from 47 381 births to women with low-risk pregnancies in South Auckland maternity facilities 2003-2010. Adjusted odds ratios with 95% confidence intervals were calculated for instrumental delivery, cesarean section, blood transfusion, neonatal unit admission, and perinatal mortality. Labor in birth centers was associated with significantly lower rates of instrumental delivery, cesarean section and blood transfusion compared with labor in hospital. Neonatal unit admission rates were lower for infants of nulliparous women laboring in birth centers. Intrapartum and neonatal mortality rates for birth centers were low and were not significantly different from the hospital population. Transfers to hospital for labor and postnatal complications occurred in 39% of nulliparous and 9% of multiparous labors. Risk factors identified for transfer were nulliparity, advanced maternal age, and prolonged pregnancy ≥41 weeks' gestation. Labor in South Auckland free-standing birth centers was associated with significantly lower maternal intervention and complication rates than labor in the hospital maternity unit and was not associated with increased perinatal morbidity. © 2017 Wiley Periodicals, Inc.

After 14 years of decline, the percentage of home births rose by 29% from 2004 to 2009, to the point where it is at the highest level since data on this item began to be collected in 1989. The overall increase in home births was driven mostly by a 36% increase for non-Hispanic white women. About 1 out of every 90 births to non-Hispanic white women are now home births. The percentage of home births for non-Hispanic white women was three to five times higher than for any other racial or ethnic group. Home births have a lower risk profile than hospital births, with fewer births to teenagers or unmarried women, and with fewer preterm, low birthweight, and multiple births. The lower risk profile of home compared with hospital births suggests that home birth attendants are selecting low-risk women as candidates for home birth. The increase in the percentage of home births from 2004 to 2009 was widespread and involved selected states from every region of the country. The large variations in the percentage of home births by state may be influenced by differences among states in laws pertaining to births are more prevalent among non-Hispanic white women (7). midwifery practice or out-of-hospital birth (8,9), as well as by differences in the racial and ethnic composition of state populations, as home Studies have suggested that most home births are intentional or planned home births, whereas others are unintentional or unplanned, because of an emergency situation (i.e., precipitous labor, labor complications, or unable to get to the hospital in time) (3,6). Although not representative of all U.S. births (see "Data source and methods"), 87% of home births in a 26-state reporting area (comprising 50% of U.S. births) were planned in 2009. For non-Hispanic white women, 93% of home births were planned (10). Women may prefer a home birth over a hospital birth for a variety of reasons, including a desire for a low-intervention birth in a familiar environment surrounded by family

Objective Very low birth weight (VLBW) infants are at high risk for morbidity and mortality. This article determines the frequency of disease, rate od survival, complications and risk factors for morbidity and mortality in VLBW neonates admitted to a level III neonatal intensive care unit (NICU) at Mahdieh Hospital in Tehran. Methods This cross-sectional retrospective study was performed from April 2007 to March 2010 on all hospitalized VLBW neonates. Relevant pre- and peri-natal data up to the time of discharge from the hospital or death, including complications during the course of hospitalization, were collected from the case notes, documented on a pre-designed questionnaire and analyzed. Findings Out of 13197 neonates, 564 (4.3%) were VLBW with 51.4% males. Mean gestational age was 29.6±2.5 weeks; mean birth weight 1179±257 grams. Mean birth weight, gestational age and Apgar scores were significantly higher in babies who survived than in those who died, (1275±189 vs. 944±253 grams; 30.5±2.2 vs. 27.5±2 weeks and 6.9±1.7 vs. 5±2.1 respectively, P<0.001 in all instances). Overall survival was 70.9%; in extremely low birth weight (ELBW) newborns this figure was 33.3% rising to 84.1% in infants weighing between 1001-1500 grams. Respiratory failure resulting from RDS in ELBW babies was the major factor leading to death. Need for mechanical ventilation, pulmonary hemorrhage and gastro-intestinal bleeding were also significant predictive factors for mortality. Conclusion Birth weight and mechanical ventilation are the major factors predicting VLBW survival. PMID:24800021

Previous studies have reported strong associations between birth order, maternal age, and suicide, but these results might have been confounded by socioeconomic and other factors. To control for such factors, we compared suicide risk between siblings and studied how maternal age at child birth and birth order influenced risk in a cohort study of 1,690,306 Norwegians born in 1967-1996 who were followed up until 2008. Using stratified Cox regression, we compared suicide risk within families with 2 or more children in which one died from suicide. Altogether, 3,005 suicides occurred over a mean follow-up period of 15 years; 2,458 of these suicides occurred among 6,741 siblings within families of 2 or more siblings. Among siblings, a higher position in the birth order was positively associated with risk; each increase in birth order was associated with a 46% (adjusted hazard ratio = 1.46, 95% confidence interval: 1.29, 1.66) higher risk of suicide. For each 10-year increase in maternal age at child birth, the offspring's suicide risk was reduced by 57% (adjusted hazard ratio = 0.43, 95% confidence interval: 0.30, 0.62). Our study suggests that confounding due to familial factors is not likely to explain the associations of birth order and maternal age at child birth with suicide risk.

To evaluate the safety of home births in North America involving direct entry midwives, in jurisdictions where the practice is not well integrated into the healthcare system. Prospective cohort study. All home births involving certified professional midwives across the United States (98% of cohort) and Canada, 2000. All 5418 women expecting to deliver in 2000 supported by midwives with a common certification and who planned to deliver at home when labour began. Intrapartum and neonatal mortality, perinatal transfer to hospital care, medical intervention during labour, breast feeding, and maternal satisfaction. 655 (12.1%) women who intended to deliver at home when labour began were transferred to hospital. Medical intervention rates included epidural (4.7%), episiotomy (2.1%), forceps (1.0%), vacuum extraction (0.6%), and caesarean section (3.7%); these rates were substantially lower than for low risk US women having hospital births. The intrapartum and neonatal mortality among women considered at low risk at start of labour, excluding deaths concerning life threatening congenital anomalies, was 1.7 deaths per 1000 planned home births, similar to risks in other studies of low risk home and hospital births in North America. No mothers died. No discrepancies were found for perinatal outcomes independently validated. Planned home birth for low risk women in North America using certified professional midwives was associated with lower rates of medical intervention but similar intrapartum and neonatal mortality to that of low risk hospital births in the United States.

Studies in developed countries have shown that reduced fetal growth is related to raised blood pressure in childhood and adult life. Little is known about this association in developing countries, where fetal growth retardation is common. In 1994-1995, we measured blood pressure in 1570 3-6-year-old children living in China, Guatemala, Chile, Nigeria and Sweden. We related their blood pressure to patterns of fetal growth, as measured by body proportions at birth. The children were all born after 37 weeks gestation and weighed more than 2.5 kg at birth. In each country, blood pressure was positively related to the child's current weight. After adjusting for this and gender, systolic pressure was inversely related to size at birth in all countries except Nigeria. In Chile, China and Guatemala, children who were proportionately small at birth had raised systolic pressure. For example, in Chile, systolic pressure adjusted for current weight increased by 4.9 mmHg (95% CI : 2.1, 7.7) for every kilogram decrease in birthweight, by 1 mmHg (95% CI : 0.4, 1.6) for every centimetre decrease in birth length, and by 1.3 mmHg (95% CI : 0.4, 2.2) for every centimetre decrease in head circumference at birth. In Sweden, systolic pressure was higher in children who were disproportionately small, that is thin, at birth. Systolic pressure increased by 0.3 mmHg (95% CI : 0.0, 0.6) for every unit (kg/m3) decrease in ponderal index at birth. These associations were independent of the duration of gestation. Raised blood pressure among children in three samples from China, Central and South America is related to proportionate reduction in body size at birth, which results from reduced growth throughout gestation. The relation between fetal growth and blood pressure may be different in African populations. Proportionately reduced fetal growth is the prevalent pattern of fetal growth retardation in developing countries, and is associated with chronic undernutrition among women. Improvement

Implementing national home birth guidelines for certified nurse-midwives (CNMs) and certified midwives (CMs) in the United States may facilitate a common approach to safe home birth practices. Guidelines are evidence-based care recommendations for specified clinical situations that can be modified by individual providers to meet specific client needs. Following a review of home birth guidelines from multiple countries, a set of home birth practices guidelines for US CNMs/CMs was drafted. Fifteen American Midwifery Certification Board, Inc. (AMCB)-certified home birth midwives who participate in the American College of Nurse-Midwives (ACNM) home birth electronic mailing list considered the use of such a document in their practices and reviewed and commented on the guidelines. The proposed guidelines addressed client screening, informed consent, antepartum care, routine intrapartum care, obstetric complications and hospital transports, postpartum care, neonatal care, gynecologic care, primary care, peer reviews, recordkeeping, and physician collaboration. The reviewers had varying assessments as to whether the guidelines reflected international standards and current best evidence. The primary concern expressed was that an adoption of national guidelines could compromise provider autonomy. Incorporation of evidence-based guidelines is an ACNM standard and was recommended by the Home Birth Consensus Summit. Clinical practice guidelines are informed by current evidence and supported by experts in a given discipline. Implementation of guidelines ensures optimal patient care and is becoming increasingly central to reimbursement and to medicolegal support. A set of practice guidelines based on current best evidence and internationally accepted standards was developed and reviewed by an interested group of US CNMs/CMs. Further discussion with home birth midwives and other stakeholders about the development and implementation of home birth guidelines is needed, especially in

Data from the National Vital Statistics System •Birth rates for teenagers aged 15-19 declined in urban and rural counties from 2007 through 2015, with the largest declines in large urban counties and the smallest declines in rural counties. •From 2007 through 2015, the teen birth rate was lowest in large urban counties and highest in rural counties. •Declines in teen birth rates in all urban counties between 2007 and 2015 were largest in Arizona, Massachusetts, Connecticut, Minnesota, and Colorado, with 17 states experiencing a decline of 50% or more. •Declines in teen birth rates in all rural counties between 2007 and 2015 were largest (50% or more) in Colorado and Connecticut. •In 2015, teen birth rates were highest in rural counties and lowest in large urban counties for non-Hispanic white, non-Hispanic black, and Hispanic females. Teen birth rates have demonstrated an unprecedented decline in the United States since 2007 (1). Declines occurred in all states and among all major racial and Hispanic-origin groups, yet disparities by both geography and demographic characteristics persist (2,3). Although teen birth rates and related declines have been described by state, patterns by urban-rural location have not yet been examined. This report describes trends in teen birth rates in urban (metropolitan) and rural (nonmetropolitan) areas in the United States overall and by state from 2007 through 2015 and by race and Hispanic origin for 2015.

Why do women choose an unregulated birth worker to birth at home in Australia: a qualitative study.

Rigg, Elizabeth Christine; Schmied, Virginia; Peters, Kath; Dahlen, Hannah Grace

2017-03-28

In Australia the choice to birth at home is not well supported and only 0.4% of women give birth at home with a registered midwife. Recent changes to regulatory requirements for midwives have become more restrictive and there is no insurance product that covers private midwives for intrapartum care at home. Freebirth (planned birth at home with no registered health professional) with an unregulated birth worker who is not a registered midwife or doctor (e.g. Doula, ex-midwife, lay midwife etc.) appears to have increased in Australia. The aim of this study is to explore the reasons why women choose to give birth at home with an unregulated birth worker (UBW) from the perspective of women and UBWs. Nine participants (five women who had UBWs at their birth and four UBWs who had themselves used UBWs in the past for their births) were interviewed in-depth and the data analysed using thematic analysis. Four themes were found: 'A traumatising system', 'An inflexible system'; 'Getting the best of both worlds' and 'Treated with love and respect versus the mechanical arm on the car assembly line'. Women interviewed for this study either experienced or were exposed to mainstream care, which they found traumatising. They were not able to access their preferred birth choices, which caused them to perceive the system as inflexible. They interpreted this as having no choice when choice was important to them. The motivation then became to seek alternative options of care that would more appropriately meet their needs, and help avoid repeated trauma through mainstream care. Women who engaged UBWs viewed them as providing the best of both worlds - this was birthing at home with a knowledgeable person who was unconstrained by rules or regulations and who respected and supported the woman's philosophical view of birth. Women perceived UBWs as not only the best opportunity to achieve a natural birth but also as providing 'a safety net' in case access to emergency care was required.

The study conducted on a total of 1344 preterm births, of which 403 hypotrophic fetuses births (between 2010-2012 within the Maternal Clinics of Craiova, Romania), studied the involvement of dental inflammatory infections in the chorioamnionitis onset. The possibility of transferring germs, toxins and degraded materials into the blood flow, and them entering the chorioamniotic structures is quite a common issue. Subclinically often evolving chorioamniotic membrane and its existence is clearly established after birth by histopathological and bacteriological examinations, being partially responsible for the growth delay of the conception product. Our study revealed this fact, by using clinical examinations, ultrasound exams, bacteriological determinations of the amniotic fluid and the placenta, alongside the histopathological examinations. The chorioamnionitis inflammatory process is responsible for premature birth, through a high synthesis of interleukins (IL) and prostaglandins, causing uterine contractions. Our IL-6 dosage determinations show its growth that can be considered a prediction marker for preterm birth.

This article addresses the recrudescence of and new support for midwife-supervised planned home birth in the United States and the other developed countries in the context of professional responsibility. Advocates of planned home birth have emphasized patient safety, patient satisfaction, cost effectiveness, and respect for women's rights. We provide a critical evaluation of each of these claims and identify professionally appropriate responses of obstetricians and other concerned physicians to planned home birth. We start with patient safety and show that planned home birth has unnecessary, preventable, irremediable increased risk of harm for pregnant, fetal, and neonatal patients. We document that the persistently high rates of emergency transport undermines patient safety and satisfaction, the raison d'etre of planned home birth, and that a comprehensive analysis undermines claims about the cost-effectiveness of planned home birth. We then argue that obstetricians and other concerned physicians should understand, identify, and correct the root causes of the recrudescence of planned home birth; respond to expressions of interest in planned home birth by women with evidence-based recommendations against it; refuse to participate in planned home birth; but still provide excellent and compassionate emergency obstetric care to women transported from planned home birth. We explain why obstetricians should not participate in or refer to randomized clinical trials of planned home vs planned hospital birth. We call on obstetricians, other concerned physicians, midwives and other obstetric providers, and their professional associations not to support planned home birth when there are safe and compassionate hospital-based alternatives and to advocate for a safe home-birth-like experience in the hospital.

Background: The moment of birth is seen as a miracle, a journey and even a religious act. Research stress how giving birth might facilitate interference with previous conceptions of how to make meaning of life existentially. However, birth as an existential life transformative event, has been...... explored only briefly in empirical research. The aim of this study was two-fold: Firstly, to explore how first-time mothers experienced their first birth in relation to existential meaning-making. Secondly, to describe the relationship between considerations related to existential meaning-making and time...... of birth. Method: The study was based on a nationwide questionnaire, conducted among Danish first time mothers, who had given birth either preterm or full-term (n=517). The questionnaire consisted of 46 overall items. Eight core items were analysed in this study. Findings Preliminary findings show that new...

Ordinal position the child holds within the sibling ranking of a family is related to intellectual functioning, personality, behavior, and development of psychopathology. To study the association between birth order and development of psychopathology in patients attending psychiatry services in a teaching hospital. Hospital-based cross-sectional study. Retrospective file review of three groups of patients was carried out. Patient-related variables like age of onset, birth order, family type, and family history of mental illness were compared with psychiatry diagnosis (ICD-10) generated. SPSS 13; descriptive statistics and one-way analysis of variance (ANOVA) were used. Mean age of onset of mental illness among the adult general psychiatry patients (group I, n = 527) was found to be 33.01 ± 15.073, while it was 11.68 ± 4.764 among the child cases (group II, n = 47) and 26.74 ± 7.529 among substance abuse cases (group III, n = 110). Among group I patients, commonest diagnosis was depression followed by anxiety and somatoform disorders irrespective of birth order. Dissociative disorders were most prevalent in the first born child (36.7%) among group II patients. Among group III patients, alcohol dependence was maximum diagnosis in all birth orders. Depression and alcohol dependence was the commonest diagnosis in adult group irrespective of birth order.

Prevalence and predictors of antibiotic administration during pregnancy and birth.

Jakob Stokholm

Full Text Available BACKGROUND: Antibiotic treatment during pregnancy and birth is very common. In this study, we describe the estimated prevalence of antibiotic administration during pregnancy and birth in the COPSAC2010 pregnancy cohort, and analyze dependence on social and lifestyle-related factors. METHODS: 706 pregnant women from the novel unselected Copenhagen Prospective Study on Asthma in Childhood (COPSAC2010 pregnancy cohort participated in this analysis. Detailed information on oral antibiotic prescriptions during pregnancy filled at the pharmacy was obtained and verified longitudinally. Information on intrapartum antibiotics, social, and lifestyle-factors was obtained by personal interviews. RESULTS: The prevalence of antibiotic use was 37% during pregnancy and 33% intrapartum. Lower maternal age at birth; adjusted odds ratio (aOR 0.94, 95% CI, [0.90-0.98], p = 0.003 and maternal smoking; aOR 1.97, 95% CI, [1.07-3.63], p = 0.030 were associated with use of antibiotics for urinary tract infection during pregnancy. Maternal educational level (low vs. high, aOR 2.32, 95% CI, [1.24-4.35], p = 0.011, maternal asthma; aOR 1.99, 95% CI, [1.33-2.98], p < 0.001 and previous childbirth; aOR 1.80, 95% CI, [1.21-2.66], p = 0.004 were associated with use of antibiotics for respiratory tract infection during pregnancy. Lower gestational age; aOR 0.72, 95% CI, [0.61-0.85], p < 0.001, maternal smoking; aOR 2.84, 95% CI, [1.33-6.06], p = 0.007, and nulliparity; aOR 1.79, 95% CI, [1.06-3.02], p = 0.030 were associated with administration of intrapartum antibiotics in women giving birth vaginally. CONCLUSION: Antibiotic administration during pregnancy and birth may be influenced by social and lifestyle-factors. Understanding such risk factors may guide preventive strategies in order to avoid unnecessary use of antibiotics.

There is concern about the safety of homebirths, especially in women transferred to hospital during or after labour. The scope of transfer in planned home births has not been assessed in a systematic review. This review aimed to describe the proportions and indications for transfer from home to hospital during or after labour in planned home births. The databases Pubmed, Embase, Cinahl, Svemed+, and the Cochrane Library were searched using the MeSH term "home childbirth". Inclusion criteria were as follows: the study population was women who chose planned home birth at the onset of labour; the studies were from Western countries; the birth attendant was an authorised midwife or medical doctor; the studies were published in 1985 or later, with data not older than from 1980; and data on transfer from home to hospital were described. Of the 3366 titles identified, 83 full text articles were screened, and 15 met the inclusion criteria. Two of the authors independently extracted the data. Because of the heterogeneity and lack of robustness across the studies, there were considerable risks for bias if performing meta-analyses. A descriptive presentation of the findings was chosen. Fifteen studies were eligible for inclusion, containing data from 215,257 women. The total proportion of transfer from home to hospital varied from 9.9% to 31.9% across the studies. The most common indication for transfer was labour dystocia, occurring in 5.1% to 9.8% of all women planning for home births. Transfer for indication for foetal distress varied from 1.0% to 3.6%, postpartum haemorrhage from 0% to 0.2% and respiratory problems in the infant from 0.3% to 1.4%. The proportion of emergency transfers varied from 0% to 5.4%. Future studies should report indications for transfer from home to hospital and provide clear definitions of emergency transfers.

Both gestation and birth weight have significant impact on mortality and morbidity in newborn infants. Nomograms at birth allow classification of infants into small for gestational age (SGA) and large for gestational age (LGA) categories, for risk stratification and more intensive monitoring. To date, the growth charts for preterm newborn infants in Singapore are based on the Fenton growth charts, which are constructed based on combining data from various Western growth cohorts. Hence, we aim to create Singapore nomograms for birth weight, length and head circumference at birth, which would reflect the norms and challenges faced by local infants. Growth parameters of all babies born or admitted to our unit from 2001 to 2012 were retrieved. Following exclusion of outliers, nomograms for 3 percentiles of 10th, 50th, and 90th were generated for the gestational age (GA) ranges of 25 to 42 weeks using quantile regression (QR) combined with the use of restricted cubic splines. Various polynomial models (second to third degrees) were investigated for suitability of fit. The optimum QR model was found to be a third degree polynomial with a single knotted cubic spline in the mid-point of the GA range, at 33.5 weeks. Check for goodness of fit was done by visual inspection first. Next, check was performed to ensure the correct proportion: 10% of all cases fall above the upper 90th percentile and 10% fall below the lower 10th percentile. Furthermore, an alternative formula-based method of nomogram construction, using mean, standard deviation (SD) and assumption of normality at each gestational age, was used for counterchecking. A total of 13,403 newborns were included in the analysis. The new infant-foetal growth charts with respect to birth weight, heel-crown length and occipitofrontal circumference from 25 to 42 weeks gestations with the 10th, 50th and 90th were presented. Nomograms for birth weight, length and head circumference at birth had significant impact on neonatal

Background There is a lack of data on the safety of midwife-led maternity care in remote or indigenous communities. In a de facto natural “experiment”, birth outcomes were assessed by primary birthing attendant in two sets of remote Inuit communities. Methods A geocoding-based retrospective birth cohort study in 14 Inuit communities of Nunavik, Canada, 1989–2000: primary birth attendants were Inuit midwives in the Hudson Bay (1529 Inuit births) vs western physicians in Ungava Bay communities (1197 Inuit births). The primary outcome was perinatal death. Secondary outcomes included stillbirth, neonatal death, post-neonatal death, preterm, small-for-gestational-age and low birthweight birth. Multilevel logistic regression was used to obtain the adjusted odds ratios (aOR) controlling for maternal age, marital status, parity, education, infant sex and plurality, community size and community-level random effects. Results The aORs (95% confidence interval) for perinatal death comparing the Hudson Bay vs Ungava Bay communities were 1.29 (0.63 to 2.64) for all Inuit births and 1.13 (0.48 to 2.47) for Inuit births at ≥28 weeks of gestation. There were no statistically significant differences in the crude or adjusted risks of any of the outcomes examined. Conclusion Risks of perinatal death were somewhat but not significantly higher in the Hudson Bay communities with midwife-led maternity care compared with the Ungava Bay communities with physician-led maternity care. These findings are inconclusive, although the results excluding extremely preterm births are more reassuring concerning the safety of midwife-led maternity care in remote indigenous communities.
