    Moore, Kristin A., Comp.; Snyder, Nancy O., Comp.

    Between 1986 and 1991 the teen birth rate rose by nearly one-fourth, although very small declines were evident in 1992 and 1993. This decline was concentrated among older teens; the number of births to adolescents aged 17 and younger continued to rise. The percentage of teen births that occurred outside of marriage rose to 72%. In 1991, the most…

    CHINA has achieved remarkable results in birth control since adopting a basic state policy of family planning to control the birth rate and increase the population quality. According to the "1997 Statistic Bulletin for National Economy and Social Development," a document recently issued by the State Statistics Bureau, China maintained a low birth rate of 16.57 per thousand in 1997—a natural population growth of one percent. Women of child-bearing age now average about two births each, a decrease from six in 1970.

    We further study the kinetic behavior of the exchange-driven growth with birth and death for the case of birth rate kernel being less than that of death based on the mean-field theory. The symmetric exchange rate kernel is K(k,j) = K'(k,j) = Ikjv, and the birth and death rates are proportional to the aggregate's size. The long time asymptotic behavior of the aggregate size distribution ak(t) is found to obey a much unusual scaling law with an exponentially growing scaling function φ(x) = exp(x).

    Full Text Available The changes occurred over time in the population have effects on the economy, especially the reductions in thebirth rate which may lead to disturbances in the population structure. The relationship between the economic growthand the birth rate in Romania is analysed over an 11-year period, in order to see its intensity. The presentation of theevolution of the gross domestic product and of the birth rate is completed by the calculation of the Spearmancoefficient for determining the intensity of the relationship between the two indicators. The decrease of the birth rate isdetermined, to a modest extent, by the economic growth, with a wide range of factors that influence it. In this situation,the establishment and implementation of a birth rate recovery strategy is highly necessary to reduce the imbalancecreated in the population structure.

  11. Dynamics of Two Populations with Different Birth Rates

    Science.gov (United States)

    Hoffmann, Julia; Pekalski, Andrzej

    We propose a simple model describing the dynamics of a system of two populations — more numerous natives and less numerous immigrants. The immigrants' birth rate is higher than that of the natives. Several modifications of this model taking into account changes of the birth rates due to external factors and/or possibility of contacts between the populations, are also introduced. The model is studied within two approaches — by solving a set of differential equations and through a Monte Carlo simulations. We show that the question of which population will eventually dominate depends on such factors as the probability of producing offsprings of mixed origin, assimilation of the immigrants, the ratio of the birth rates, initial numbers of the populations and the average age of an individual. In all, but two extreme cases, both populations will survive.

    Full Text Available A high educational attainment is shown to have a positive effect on second birth rates for Danish one-child mothers during the period 1981-94. We examine whether a time-squeeze is a possible explanation: due to the longer enrolment in the educational system, highly educated women have less time at their disposal in order to get the desired number of children. Also, we examine to what extent the partner's education can explain some of the positive effect. We find no evidence that the positive effect of education is due to either a time-squeeze nor to a partner effect.

    Full Text Available Abstract Background It is unclear whether the high rates of low birth weight in South Asia are due to poor fetal growth or short pregnancy duration. Also, it is not known whether the traditional focus on preventing low birth weight has been successful. We addressed these and related issues by studying births in Kaniyambadi, South India, with births from Nova Scotia, Canada serving as a reference. Methods Population-based data for 1986 to 2005 were obtained from the birth database of the Community Health and Development program in Kaniyambadi and from the Nova Scotia Atlee Perinatal Database. Menstrual dates were used to obtain comparable information on gestational age. Small-for-gestational age (SGA live births were identified using both a recent Canadian and an older Indian fetal growth standard. Results The low birth weight and preterm birth rates were 17.0% versus 5.5% and 12.3% versus 6.9% in Kaniyambadi and Nova Scotia, respectively. SGA rates were 46.9% in Kaniyambadi and 7.5% in Nova Scotia when the Canadian fetal growth standard was used to define SGA and 6.7% in Kaniyambadi and Conclusion High rates of fetal growth restriction and relatively high rates of preterm birth are responsible for the high rates of low birth weight in South Asia. Increased emphasis is required on health services that address the morbidity and mortality in all birth weight categories.

  3. Links between environmental geochemistry and rate of birth defects: Shanxi Province, China

    International Nuclear Information System (INIS)

    The rate of birth defects in Shanxi Province is among the highest worldwide. In order to identify the impacts of geochemical and environmental factors on birth defect risk, samples of soil, water and food were collected from an area with an unusually high rate of birth defects (study area) and an area with a low rate of birth defects (control area) in Shanxi Province, China. Element contents were determined by ICP-OES, and the results were analyzed using a non-parametric test and stepwise regression. Differences in the level and distribution of 14 geochemical elements, namely arsenic (As), selenium (Se), molybdenum (Mo), zinc (Zn), strontium (Sr), iron (Fe), tin (Sn), magnesium (Mg), vanadium (V), calcium (Ca), copper (Cu), aluminum (Al), potassium (K) and sulfur (S) were thus compared between the study and control areas. The results reveal that the geochemical element contents in soil, water and food show a significant difference between the study area and control area, and suggest that the study area was characterized by higher S and lower Sr and Al contents. These findings, based on statistical analysis, may be useful in directing further epidemiological investigations identifying the leading causes of birth defects. - Research Highlights: → Environmental geochemistry has an significant impact on birth defects in the regions with an unusually high rate of birth defects. → An excess of S and deficiency of Sr and Al are the distinctive environmental features associated with the high rate of birth defects in the Shanxi Province of China. → Geochemical anomalies is a non-medical basis for effective prevention and cure of birth defects.

  4. Child mortality estimation: consistency of under-five mortality rate estimates using full birth histories and summary birth histories.

    Directory of Open Access Journals (Sweden)

    Romesh Silva

    Full Text Available BACKGROUND: Given the lack of complete vital registration data in most developing countries, for many countries it is not possible to accurately estimate under-five mortality rates from vital registration systems. Heavy reliance is often placed on direct and indirect methods for analyzing data collected from birth histories to estimate under-five mortality rates. Yet few systematic comparisons of these methods have been undertaken. This paper investigates whether analysts should use both direct and indirect estimates from full birth histories, and under what circumstances indirect estimates derived from summary birth histories should be used. METHODS AND FINDINGS: Usings Demographic and Health Surveys data from West Africa, East Africa, Latin America, and South/Southeast Asia, I quantify the differences between direct and indirect estimates of under-five mortality rates, analyze data quality issues, note the relative effects of these issues, and test whether these issues explain the observed differences. I find that indirect estimates are generally consistent with direct estimates, after adjustment for fertility change and birth transference, but don't add substantial additional insight beyond direct estimates. However, choice of direct or indirect method was found to be important in terms of both the adjustment for data errors and the assumptions made about fertility. CONCLUSIONS: Although adjusted indirect estimates are generally consistent with adjusted direct estimates, some notable inconsistencies were observed for countries that had experienced either a political or economic crisis or stalled health transition in their recent past. This result suggests that when a population has experienced a smooth mortality decline or only short periods of excess mortality, both adjusted methods perform equally well. However, the observed inconsistencies identified suggest that the indirect method is particularly prone to bias resulting from violations

    Reports based on national registers of congenital malformations have suggested that the birth rate of hypospadias has increased during the last few decades. Register-based information may, however, have pitfalls because of changes in diagnostics, reporting accuracy and registration system. The aim...... of this study was to determine the current birth rate of hypospadias in Turku University Central Hospital (TUCH) in Finland. This was a prospective study on live-born boys born in TUCH from 1997 to 1999. In the total birth cohort (n=5,798) as well as in a special subcohort group (n=1,505) 0.3% of...... boys had hypospadias. Only one scrotal hypospadias was found in a boy who had a chromosomal anomaly. Other hypospadias were glandular or coronal.

  8. The influence of the post-Chernobyl fallout on birth defects and abortion rates in Austria.

    1992-10-01

    Researchers analyzed data on 66,743 births which occurred between 1985-1989 in the Styria region in southern Austria to determine whether radioactive fallout from the meltdown of the nuclear reaction at Chernobyl in the Ukraine, USSR in may 1986 affected the birth defect and abortion rates in this area of Austria. There were 1695 birth defect cases. Of the birth defects which occurred during embryogenesis, most occurred 14-49 days postconception (group 2; n=630). The researchers did not note a short-term effect of the fallout in group 2 or the other groups (relative risk= 0.75, 0.73 for group 1, and 0.93 for group 2). Baseline birth defect rates (per 1000 births) for groups 1, 2, and 3 were 2.5, 8.5, and 1,8 respectively. The only sizable increase occurred in group 2 at years 2 and 3 (10.6 and 10.3, respectively). More reported minor congenital defect cases accounted for this increase due to the newly established data base in the Department of Pediatric Cardiology at the University of Graz. Thus the increase was an artifact and not a true increase. Abortion rates varied from 10% to 14% and did not increase significantly after Chernobyl. Counseling frequency at abortion clinics fluctuated greatly (117-205) both before and after Chernobyl and the changes were not significant. These results indicated that the low dosage of radiation did not have a detectable biologic effect in terms of birth defects and abortions. The researchers addressed the difficulties with measuring teratologic potential of low dose radiation. They also highlighted the need for accurate categorizing of birth defects, adequate baseline data, and very reliable registries. Future research on possible environmental disasters which affect Austria can use these data as baseline data. PMID:1415387

    2010-12-15

    We performed a simulation of the two-species plant-herbivore system by using the agent-based NetLogo program and constructed a dynamic model of populations consistent with the simulation results. The dynamic model is a three-dimensional system including the mean energy of the herbivore in addition to two variables denoting the populations of plants and herbivores. A steady-state analysis of the dynamic model shows that the dependence of the herbivore population on the birth and the death rates observed from the agent model is consistent with the prediction of the dynamic model. Especially, the anomalous dependence of the herbivore population on the birth rate, where the population decreases with the birth rate for small death rate, is consistently explained by a phase plane analysis of the dynamic model.

    OBJECTIVES: We sought evidence to support the hypothesis that advancing maternal age is potentially causing a rise in preterm birth (PTB) rates in high-income countries. METHODS: We assessed maternal age-specific trends in PTB using all singleton live births in Denmark (n = 1 674 308) and Quebec (n...... = 2 291 253) from 1981 to 2008. We decomposed the country-specific contributions of age-specific PTB rates and maternal age distribution to overall PTB rates over time. RESULTS: PTB rates increased from 4.4% to 5.0% in Denmark and from 5.1% to 6.0% in Quebec. Rates increased the most in women aged 20...... increased among women aged 20 to 29 years, but their contribution to the overall PTB rates was offset by older maternal age over time. Women aged 20 to 29 years should be targeted to reduce PTB rates, as potential for prevention may be greater in this age group....

    International Nuclear Information System (INIS)

    The Fock-space approach to the solution of master equations for the one-step Markov processes is reconsidered. It is shown that in birth-death processes with an absorbing state at the bottom of the occupation-number spectrum and occupation-number independent annihilation probability occupation-number fluctuations give rise to rate equations drastically different from the polynomial form typical of birth-death processes. The fluctuation-induced rate equations with the characteristic exponential terms are derived for Mikhailov's ecological model and Lanchester's model of modern warfare

  12. The impact of sex ratio and economic status on local birth rates.

    Science.gov (United States)

    Chipman, A; Morrison, E

    2013-04-23

    Human mating and reproductive behaviour can vary depending on various mechanisms, including the local sex ratio. Previous research shows that as sex ratios become female-biased, women from economically deprived areas are less likely to delay reproductive opportunities to wait for a high-investing mate but instead begin their reproductive careers sooner. Here, we show that the local sex ratio also has an impact on female fertility schedules. At young ages, a female-biased ratio is associated with higher birth rates in the poorest areas, whereas the opposite is true for the richest areas. At older ages, a female-biased ratio is associated with higher birth rates in the richest, but not the poorest areas. These patterns suggest that female-female competition encourages poorer women to adopt a fast life-history strategy and give birth early, and richer women to adopt a slow life-history strategy and delay reproduction.

  14. An energy-saving development initiative increases birth rate and childhood malnutrition in rural Ethiopia.

    2006-04-01

    Full Text Available BACKGROUND: Evolutionary life history theory predicts that, in the absence of contraception, any enhancement of maternal condition can increase human fertility. Energetic trade-offs are likely to be resolved in favour of maximizing reproductive success rather than health or longevity. Here we find support for the hypothesis that development initiatives designed to improve maternal and child welfare may also incur costs associated with increased family sizes if they do not include a family planning component. METHODS AND FINDINGS: Demographic and anthropometric data were collected in a rural Ethiopian community benefiting from a recent labour-saving development technology that reduces women's energetic expenditure (n = 1,976 households. Using logistic hazards models and general linear modelling techniques, we found that whilst infant mortality has declined, the birth rate has increased, causing greater scarcity of resources within households. CONCLUSIONS: This study is, to our knowledge, the first to demonstrate a link between a technological development intervention and an increase in both birth rate and childhood malnutrition. Women's nutritional status was not improved by the energy-saving technology, because energy was diverted into higher birth rates. We argue that the contribution of biological processes to increased birth rates in areas of the developing world without access to modern contraception has been overlooked. This highlights the continued need for development programmes to be multisectoral, including access to and promotion of contraception.

Methods We examined data reported to the CDC in 2013 for the impact of embryo banking exclusion on national ART outcomes by recalculating autologous oocyte ART live birth rates. Inflation of reported fresh ART cycle live birth rates was assessed for all age groups of infertile women as the difference between fresh cycle live births with reference to number of initiated fresh cycles (excluding embryo banking cycles), as typically reported by the CDC, and fresh cycle live births with reference to total initiated fresh ART cycles (including embryo banking cycles). Results During 2013, out of 121,351 fresh non-donor ART cycles 27,564 (22.7%) involved embryo banking. The proportion of banking cycles increased with female age from 15.5% in women 44 years. Concomitantly, the proportion of thawed cycles decreased with advancing female age (P 44. The inflation of live birth rates in thawed cycles could not be calculated from the publically available CDC data but appears to be even greater. Conclusions Utilization of embryo banking increased during 2013 with advancing female age, suggesting a potential age selection bias. Exclusion of embryo banking cycles from national ART outcome reports significantly inflated national ART success rates, especially among older women. Précis Exclusion of embryo banking cycles from US National Assisted Reproductive Technology outcome reports significantly inflates reported success rates especially in older women. PMID:27159215

    Full Text Available Recent advances in informatics technology has made it possible to integrate, manipulate, and analyze variables from a wide range of scientific disciplines allowing for the examination of complex social problems such as health disparities. This study used 589 county-level variables to identify and compare geographical variation of high and low preterm birth rates. Data were collected from a number of publically available sources, bringing together natality outcomes with attributes of the natural, built, social, and policy environments. Singleton early premature county birth rate, in counties with population size over 100,000 persons provided the dependent variable. Graph theoretical techniques were used to identify a wide range of predictor variables from various domains, including black proportion, obesity and diabetes, sexually transmitted infection rates, mother’s age, income, marriage rates, pollution and temperature among others. Dense subgraphs (paracliques representing groups of highly correlated variables were resolved into latent factors, which were then used to build a regression model explaining prematurity (R-squared = 76.7%. Two lists of counties with large positive and large negative residuals, indicating unusual prematurity rates given their circumstances, may serve as a starting point for ways to intervene and reduce health disparities for preterm births.

  17. Coital rates, sex-selective infanticide, and sex ratios at birth.

    James, W H

    The author of this short article comments on the suggestion by Brewis and Underwood, in their report on Micronesia, that the high sex ratios at birth were due to the high coital rates (greater than 108-110). First, in Australia, the reported sex ratio of births conceived in the first month of marriage from 1908 to 1967 was 109. Mean reported marital coital rates during the first month of marriage for the United States and England are estimated to be 20 per month. The average coital rate is higher among women who conceive. If the variation of sex ratios across societies were explained by coital rates alone, Micronesian coital rates would have to be much greater than 20 per month throughout couples' reproductive lives, and 3 times the averages in postindustrial countries. Such coital rates have not been substantiated; other reasons may account for the high sex ratios in Micronesia. Brewis and Underwood stated that they did not believe sex-selective infanticide was an explanation of the high sex ratios; this may have been based on current practices. Yet past practices of sex-selective infanticide could influence current sex ratios, given that there is mathematical evidence that genetics may influence the probability of producing a child of a particular sex. Therefore, the average current sex ratio at conception and birth of a population depends on: the magnitude of the genetic component of the Lexis variance (the reproductive-lifetime probability of a couple's producing a boy at each birth); and 2) the extent of the sex-selective infanticide in the past. The total extent of the Lexis variance, including its genetic component, is unknown. PMID:8909113

    Full Text Available Context : Most in vitro fertilization (IVF programs employ embryo cryopreservation to enhance pregnancies from a single ovarian stimulation. More embryos are created, some of which are not transferred to the uterus immediately, generating a need for improved cryopreservation protocols. One protocol may involve growing embryos to a further stage of development, allowing only embryos with proven developmental capabilities to be cryopreserved. Here we examined thaw survival, implantation and live birth rates of embryos cryopreserved at different stages. Aims : We examined thaw survival, implantation and live birth rates of embryos cryopreserved at the zygote, day 3 (D3 embryos or blastocyst stage. Settings and Design : This is a retrospective study from a single academic IVF program. Patients and Methods :0 A retrospective study of all patients who had frozen embryos transferred to their uteri from year 2002 to 2008 at a single academic IVF program was conducted. Statistical Analysis Used : Analysis of variance followed by Fisher′s Exact Test was performed to compare the survival after thaw, implantation and live birth rates between the three groups. Results : One thousand nine hundred and ninety-one zygotes, 2880 D3 embryos and 503 blastocysts were frozen using a slow freeze technique, thawed and transferred. Significantly more D3 embryos and blastocysts survived the thawing process compared to zygotes and significantly higher implantation rate per number of thawed blastocysts was achieved than that for zygotes. Live birth rates were similar between the three groups. Conclusions : Growing embryos to blastocyst stage prior to cryopreservation is associated with fewer frozen embryos but does not appear compromise patients′ chance of achieving pregnancy

    Full Text Available Background and Aim: Preterm birth is one of the risk factors need comprehensive audiological assessment. In this study, the effect of sex and rate of stimulation on response of children with history of preterm birth was investigated by auditory brainstem response (ABR. Methods: This cross-sectional study was conducted using convinience sampling. Click-evoked a uditory brainstem response test with both low (21.1 c/s and high (51.1 c/s stimulus rates was recorded in 30 children with a history of preterm birth and 30 ones with history of term labor, as controls. Results: Significant differences were observed in inter-peak latencies of I-III in both rates, III-V in the low rate, I-V in the high rate, and absolute latency of III wave between high and low stimulus rates (p<0.05 for all. Rate of stimulus affect on auditory brainstem response of preterm birth group was more than controls. Sex also affected on some parameters of auditory brainstem response test. Conclusion: Preterm birth group showed longer latencies than normal group in both rates. Rate of stimulus had significant effect on results of children with history of preterm birth compared normal group. These findings may reflect the negative effect of preterm birth on neural synchronization function in response to transient stimuli.

    Fertility differences in Europe are largely due to disparities in parity progression after the first child. Postponement is recuperated to a larger extent in countries with relatively high fertility, less in countries with very low fertility. Explanations have referred to social policy and socio-economic context. We argue that cultural factors also need to be taken into account and investigate the relationship between age norms and second birth rates in 23 European countries. Usin...

  1. Hungarian Population Discourses in the Twentieth Century: The Problem of Declining Birth Rates

    2016-01-01

    Full Text Available Falling birth rates had already been recorded as early as the late-eighteenth century in south-western Hungary in the Ormánság. Population loss from low birth rate remained one of the main topics writers and sociologists focused on in the twentieth century. The issue of Hungarian population decline was highlighted among the social ills in the interwar period, which was one of several subjects that divided intellectuals into ‘populists’ and ‘urbanites’. Following the impact of the low birth rate figures in the 1960s, the populists’ views of the 1930s resurfaced in public discourse in the 1960s and 1970s and up to the present day. The concern about the increasing trend of single-child families in rural settlements as well as in urban areas appeared in the various works of Hungarian writers and journalists throughout the previous century. The present paper intends to focus on the intellectual background to the public debates on the population issue, outlining the accounts of the interwar ‘village explorers’ briefly, and the way they are related to the pre-Second World War populist movement. Finally the reappearance of the debates between populists and non-populists of the 1970s is discussed, a debate that is still continuing.

    The analysis of mark-recapture data is undergoing a period of development and expansion. Here we contribute to that by presenting a model which includes both births and immigration, as well as the usual deaths. Data come from a long-term study of the willow tit (Parus montanus), where we can assume that all births are recorded, and hence immigrants can also be identified as birds captured as adults for the first time. We model the rates of immigration, birth rate per parent, and death rates of juveniles and adults. Using a hierarchical model allows us to incorporate annual variation in these parameters. The model is fitted to the data using Markov chain Monte Carlo, as a Bayesian analysis. In addition to the model fitting, we also check several aspects of the model fit, in particular whether survival varies with age or immigrant status, and whether capture probability is affected by previous capture history. The latter check is important, as independence of capture histories is a key assumption that simplifies the model considerably. Here we find that the capture probability depends strongly on whether the individual was captured in the previous year. PMID:18479483

    Full Text Available Abstract Background Cell-cell communication and adhesion are essential for the compaction process of early stage embryos. The aim of this study was to develop a non-invasive objective calculation system of embryo compaction in order to test the hypothesis that embryos with a larger mean contact surface result in a higher live birth rate compared to embryos with a lower mean contact surface. Methods Multilevel images of 474 embryos transferred on day 3 were evaluated by the Cellify software. This software calculates the contact surfaces between the blastomeres. The primary outcome of this study was live birth. An ideal range of contact surface was determined and the positive and negative predictive value, the sensitivity, the specificity and the area under the curve for this new characteristic were calculated. Results In total, 115 (24% transferred embryos resulted in a live birth. Selection of an embryo for transfer on its mean contact surface could predict live birth with a high sensitivity (80% and high negative predicting value (83% but with a low positive predictive value (27%, a low specificity (31% and low area under the ROC curve (0.56. The mean contact surface of embryos cultured in a single medium was significantly higher compared to the mean contact surface of embryos cultured in a sequential medium (p = 0.0003. Conclusions Neither the mean contact surface nor the number of contact surfaces of a day 3 embryo had an additional value in the prediction of live birth. The type of culture medium, however, had an impact on the contact surface of an embryo. Embryos cultured in a single medium had a significant larger contact surface compared to embryos cultured in the sequential medium.

    Fetal monitoring during labour currently fails to accurately detect acidemia. We developed a method to assess the multidimensional properties of fetal heart rate variability (fHRV) from trans-abdominal fetal electrocardiogram (fECG) during labour. We aimed to assess this novel bioinformatics approach for correlation between fHRV and neonatal pH or base excess (BE) at birth.We enrolled a prospective pilot cohort of uncomplicated singleton pregnancies at 38-42 weeks' gestation in Milan, Italy, and Liverpool, UK. Fetal monitoring was performed by standard cardiotocography. Simultaneously, with fECG (high sampling frequency) was recorded. To ensure clinician blinding, fECG information was not displayed. Data from the last 60 min preceding onset of second-stage labour were analyzed using clinically validated continuous individualized multiorgan variability analysis (CIMVA) software in 5 min overlapping windows. CIMVA allows simultaneous calculation of 101 fHRV measures across five fHRV signal analysis domains. We validated our mathematical prediction model internally with 80:20 cross-validation split, comparing results to cord pH and BE at birth.The cohort consisted of 60 women with neonatal pH values at birth ranging from 7.44 to 6.99 and BE from -0.3 to -18.7 mmol L(-1). Our model predicted pH from 30 fHRV measures (R(2) = 0.90, P base balance at birth. Further refinement and validation in larger cohorts are needed. These new measurements of fHRV might offer a new opportunity to predict fetal acid-base balance at birth. PMID:25407948

    Purpose To examine pregnancy rates and outcomes (births and abortions) among 15- to 19-year olds and 10- to 14-year olds in all countries for which recent information could be obtained and to examine trends since the mid-1990s. Methods Information was obtained from countries’ vital statistics reports and the United Nations Statistics Division for most countries in this study. Alternate sources of information were used if needed and available. We present estimates primarily for 2011 and compare them to estimates published for the mid-1990s. Results Among the 21 countries with complete statistics, the pregnancy rate among 15- to 19-year olds was the highest in the United States (57 pregnancies per 1,000 females) and the lowest rate was in Switzerland (8). Rates were higher in some former Soviet countries with incomplete statistics; they were the highest in Mexico and Sub-Saharan African countries with available information. Among countries with reliable evidence, the highest rate among 10- to 14-year olds was in Hungary. The proportion of teen pregnancies that ended in abortion ranged from 17% in Slovakia to 69% in Sweden. The proportion of pregnancies that ended in live births tended to be higher in countries with high teen pregnancy rates (p =.02). The pregnancy rate has declined since the mid-1990s in the majority of the 16 countries where trends could be assessed. Conclusions Despite recent declines, teen pregnancy rates remain high in many countries. Research on the planning status of these pregnancies and on factors that determine how teens resolve their pregnancies could further inform programs and policies. PMID:25620306

    Full Text Available Abstract Background Preterm birth (PTB is a substantial health problem that accounts for significant infant morbidity and mortality and poses an economic burden to both individuals and the state of residence. The goal of this study was to identify maternal risk factors for PTB in New Mexico, a poor state with a unique ethnic background, in order to identify populations at increased risk that would benefit from intervention. Methods This was a cross-sectional retrospective exploratory analysis of 377,770 singleton live births in the state of New Mexico from 1991-2005. Gestational age of less than 37 weeks was defined as PTB. The Kotelchuck Index was used as a measure for level of prenatal care described as inadequate, intermediate, adequate, and intensive. Results Of the live births analyzed, 28,036 of these were preterm (7.4%. Overall the PTB rate rose at a rate of 0.18% per year from 1991-2005. Among patients with medical risk factors, the absence of prenatal care was associated with higher odds for PTB as compared to adequate prenatal care. Other risk factors were unmarried status, education less than high school, tobacco/alcohol use, black, Asian, and white Hispanic ethnicity, and the presence of one or more medical risk factors. Statistically significant protective factors for PTB were age 25-29, education surpassing high school, and Native American race. Conclusions This study identified several factors that correlate with increased PTB in New Mexico, in particular ethnicity and level of prenatal care. The finding that Native American patients have a lower PTB rate compared to other groups, even though this group is traditionally one of low socioeconomic status in New Mexico, signifies that other factors yet to be identified affect PTB.

    We previously demonstrated that tauroursodeoxycholic acid (TUDCA) improved the developmental competence of mouse embryos by attenuating endoplasmic reticulum (ER) stress-induced apoptosis during preimplantation development. Here, we present a follow-up study examining whether TUDCA enhances the implantation and live-birth rate of mouse embryos. Mouse 2-cell embryos were collected by oviduct flushing and cultured in the presence or absence of 50 μM TUDCA. After culture (52 h), blastocysts were transferred to 2.5-day pseudopregnant foster mothers. It was found that the rates of pregnancy and implantation as well as the number of live pups per surrogate mouse were significantly higher in the TUDCA-treated group compared to the control group, but there was no significant difference in the mean weights of the pups or placentae. Thus, we report for the first time that TUDCA supplementation of the embryo culture medium increased the implantation and livebirth rates of transferred mouse embryos. PMID:26051458

    We estimate the spatial densities of different types of neutron star near the Sun. It is shown that the distances of dim isolated thermal neutron stars must be on average about 300-400 pc. The combined birth rate of these sources together with radio pulsars and dim radio quiet neutron stars can be a little more than the supernova rate as some of the dim isolated thermal neutron stars can be formed from dim radio quiet neutron stars and radio pulsars. Some of these sources must have relations with anomalous X-ray pulsars and soft gamma repeaters. In order to understand the locations of different types of neutron star on the P-\\.{P} diagram it is also necessary to take into account the differences in the masses and the structures of neutron stars.

  14. Sex ratio at birth and mortality rates are negatively related in humans.

    Madhukar Shivajirao Dama

    Full Text Available Evolutionary theory posits that resource availability and parental investment ability could signal offspring sex selection, in order to maximize reproductive returns. Non-human studies have provided evidence for this phenomenon, and maternal condition around the time of conception has been identified as most important factor that influence offspring sex selection. However, studies on humans have reported inconsistent results, mostly due to use of disparate measures as indicators of maternal condition. In the present study, the cross-cultural differences in human natal sex ratio were analyzed with respect to indirect measures of condition namely, life expectancy and mortality rate. Multiple regression modeling suggested that mortality rates have distinct predictive power independent of cross-cultural differences in fertility, wealth and latitude that were earlier shown to predict sex ratio at birth. These findings suggest that sex ratio variation in humans may relate to differences in parental and environmental conditions.

  20. Birth rate in the population exposed to radiation in the villages along the Techa river

    International Nuclear Information System (INIS)

    Disposal of radioactive waste of a radiochemical plant engaged in the manufacture of plutonium (Mayak Industrial Amalgamation) into the river Techa in the Southern (Urals in 1949-1956 led to chronic exposure of 28,000 subjects living in villages on the banks of this river. The doses absorbed in the gonads varied from 34 mSv to 1270 mSv at the expense of external exposure and incorporation of radioactive cesium. The register of the progeny of the first generation irradiated includes 20278 subjects. Based on this register, the author analyzes the birth rates among the irradiated population and the sex ratio in the new generation and comes to a conclusion that exposure in the beforesaid doses did not impair the reproductive function of irradiated subjects. 9 refs., 4 figs., 2 tabs,

  1. Impact of agricultural modernization on crude birth rate in Indian Punjab.

    Science.gov (United States)

    Ali, K

    1981-01-01

    This paper explores the effects of agricultural change on several socioeconomic and demographic characteristics that influence fertility decisions in 11 districts of the Indian Punjab from 1961-71. The basis of the study relates to a household production model which embodies birth rate and infant mortality rate as endogenous variables. Linkage between agricultural modernization and the above variables are discussed. The model is estimated for pooled cross-sectional and time-series observations of the 11 districts. The most important finding is that the infant mortality rate has a positive effect on fertility and, conversely, fertility rates have a positive impact on infant mortality. Agricultural improvements, if equally distributed, lead to a decline in infant mortality and fertility. Implications of the study are that the supply and demand for contraception through socioeconomic development should go hand in hand. Policy makers should attach importance to an even distribution of land and income as well as to an improvement of health and educational facilities, nutritional intake, and sanitation. PMID:12338154

    Full Text Available Preterm birth is associated with painful procedures during the neonatal intensive care unit (NICU stay. Full-term newborns can also experience pain, following surgery. These procedures can have long-lasting consequences. It has been shown that children born preterm show pain responses and cardiac alterations. This study aimed to explore the heart rate reactivity to pain in 107 subjects born either preterm or full-term who were between 7 and 25 years old at testing. We also evaluated the effect of pain experienced at birth, as represented by a longer NICU stay, time under ventilation, and surgery at birth. Participants were asked to immerse their right forearm in 10°C water for 2 minutes. Electrocardiograms were recorded at baseline and during the immersion procedure. Full-term subjects showed a stable increase in heart rate throughout the procedure, whereas preterm ones showed a strong increase at the beginning, which decreased over time. Also, preterm and full-term subjects who experienced pain at birth showed higher resting heart rate, stronger sympathetic activity, and lower cardiac vagal activity. Our study demonstrated a long-term impact of a long NICU stay and surgery at birth on cardiac autonomic activity. This could lead to impaired reactions to pain or stress in later life.

  4. THE BIRTH RATE OF SNe Ia FROM HYBRID CONe WHITE DWARFS

    International Nuclear Information System (INIS)

    Considering the uncertainties of the C-burning rate (CBR) and the treatment of convective boundaries, Chen et al. found that there is a regime where it is possible to form hybrid CONe white dwarfs (WDs), i.e., ONe WDs with carbon-rich cores. As these hybrid WDs can be as massive as 1.30 M ☉, not much mass needs to be accreted for these objects to reach the Chandrasekhar limit and to explode as Type Ia supernovae (SNe Ia). We have investigated their contribution to the overall SN Ia birth rate and found that such SNe Ia tend to be relatively young with typical time delays between 0.1 and 1 Gyr, where some may be as young as 30 Myr. SNe Ia from hybrid CONe WDs may contribute several percent to all SNe Ia, depending on the common-envelope ejection efficiency and the CBR. We suggest that these SNe Ia may produce part of the 2002cx-like SN Ia class

    Full Text Available BACKGROUND Limited information is available about teenage pregnancy and childbearing in rural areas, even though approximately 20 percent of the nation's youth live in rural areas. Identifying whether there are differences in the teenage birth rate (TBR across metropolitan and nonmetropolitan areas is important because these differences may reflect modifiable ecological-level influences such as education, employment, laws, healthcare infrastructure, and policies that could potentially reduce the TBR. OBJECTIVE The goals of this study are to investigate whether there are spatially varying relationships between the TBR and the independent variables, and if so, whether these associations differ between metropolitan and nonmetropolitan counties. METHODS We explore the heterogeneity within metropolitan/nonmetropolitan county groups separately using geographically weighted regression (GWR, and investigate the difference between metropolitan/nonmetropolitan counties using spatial regime models with spatial errors. These analyses were applied to county-level data from the National Center for Health Statistics and the US Census Bureau. RESULTS GWR results suggested that non-stationarity exists in the associations between TBR and determinants within metropolitan/nonmetropolitan groups. The spatial regime analysis indicated that the effect of socioeconomic disadvantage on TBR significantly varied by the metropolitan status of counties. CONCLUSIONS While the spatially varying relationships between the TBR and independent variables were found within each metropolitan status of counties, only the magnitude of the impact of the socioeconomic disadvantage index is significantly stronger among metropolitan counties than nonmetropolitan counties. Our findings suggested that place-specific policies for the disadvantaged groups in a county could be implemented to reduce TBR in the US.

  8. Increasing live birth rate by preimplantation genetic screening of pooled polar bodies using array comparative genomic hybridization.

    Michael Feichtinger

    Full Text Available Meiotic errors during oocyte maturation are considered the major contributors to embryonic aneuploidy and failures in human IVF treatment. Various technologies have been developed to screen polar bodies, blastomeres and trophectoderm cells for chromosomal aberrations. Array-CGH analysis using bacterial artificial chromosome (BAC arrays is widely applied for preimplantation genetic diagnosis (PGD using single cells. Recently, an increase in the pregnancy rate has been demonstrated using array-CGH to evaluate trophectoderm cells. However, in some countries, the analysis of embryonic cells is restricted by law. Therefore, we used BAC array-CGH to assess the impact of polar body analysis on the live birth rate. A disadvantage of polar body aneuploidy screening is the necessity of the analysis of both the first and second polar bodies, resulting in increases in costs for the patient and complex data interpretation. Aneuploidy screening results may sometimes be ambiguous if the first and second polar bodies show reciprocal chromosomal aberrations. To overcome this disadvantage, we tested a strategy involving the pooling of DNA from both polar bodies before DNA amplification. We retrospectively studied 351 patients, of whom 111 underwent polar body array-CGH before embryo transfer. In the group receiving pooled polar body array-CGH (aCGH analysis, 110 embryos were transferred, and 29 babies were born, corresponding to live birth rates of 26.4% per embryo and 35.7% per patient. In contrast, in the control group, the IVF treatment was performed without preimplantation genetic screening (PGS. For this group, 403 embryos were transferred, and 60 babies were born, resulting in live birth rates of 14.9% per embryo and 22.7% per patient. In conclusion, our data show that in the aCGH group, the use of aneuploidy screening resulted in a significantly higher live birth rate compared with the control group, supporting the benefit of PGS for IVF couples in

    Teen childbearing can have negative health, economic, and social consequences for mothers and their children (1) and costs the United States approximately $9.4 billion annually (2). During 1991-2014, the birth rate among teens aged 15-19 years in the United States declined 61%, from 61.8 to 24.2 births per 1,000, the lowest rate ever recorded (3). Nonetheless, in 2014, the teen birth rate remained approximately twice as high for Hispanic and non-Hispanic black (black) teens compared with non-Hispanic white (white) teens (3), and geographic and socioeconomic disparities remain (3,4), irrespective of race/ethnicity. Social determinants associated with teen childbearing (e.g., low parental educational attainment and limited opportunities for education and employment) are more common in communities with higher proportions of racial and ethnic minorities (4), contributing to the challenge of further reducing disparities in teen births. To examine trends in births for teens aged 15-19 years by race/ethnicity and geography, CDC analyzed National Vital Statistics System (NVSS) data at the national (2006-2014), state (2006-2007 and 2013-2014), and county (2013-2014) levels. To describe socioeconomic indicators previously associated with teen births, CDC analyzed data from the American Community Survey (ACS) (2010-2014). Nationally, from 2006 to 2014, the teen birth rate declined 41% overall with the largest decline occurring among Hispanics (51%), followed by blacks (44%), and whites (35%). The birth rate ratio for Hispanic teens and black teens compared with white teens declined from 2.9 to 2.2 and from 2.3 to 2.0, respectively. From 2006-2007 to 2013-2014, significant declines in teen birth rates and birth rate ratios were noted nationally and in many states. At the county level, teen birth rates for 2013-2014 ranged from 3.1 to 119.0 per 1,000 females aged 15-19 years; ACS data indicated unemployment was higher, and education attainment and family income were lower in

    Full Text Available Abstract Background In 1999, the American Academy of Pediatrics and U.S. Public Health Service recommended suspending the birth dose of hepatitis B vaccine due to concerns about potential mercury exposure. A previous report found that overall national hepatitis B vaccination coverage rates decreased in association with the suspension. It is unknown whether this underimmunization occurred uniformly or was associated with how providers changed their practices for the timing of hepatitis B vaccine doses. We evaluate the impact of the birth dose suspension on underimmunization for the hepatitis B vaccine series among 24-month-olds in five large provider groups and describe provider practices potentially associated with underimmunization following the suspension. Methods Retrospective cohort study of children enrolled in five large provider groups in the United States (A-E. Logistic regression was used to evaluate the association between the birth dose suspension and a child's probability of being underimmunized at 24 months for the hepatitis B vaccine series. Results Prior to July 1999, the percent of children who received a hepatitis B vaccination at birth varied widely (3% to 90% across the five provider groups. After the national recommendation to suspend the hepatitis B birth dose, the percent of children who received a hepatitis B vaccination at birth decreased in all provider groups, and this trend persisted after the policy was reversed. The most substantial decreases were observed in the two provider groups that shifted the first hepatitis B dose from birth to 5–6 months of age. Accounting for temporal trend, children in these two provider groups were significantly more likely to be underimmunized for the hepatitis B series at 24 months of age if they were in the birth dose suspension cohort compared with baseline (Group D OR 2.7, 95% CI 1.7 – 4.4; Group E OR 3.1, 95% CI 2.3 – 4.2. This represented 6% more children in Group D and 9

    Calving and weaning rates, birth weight, calving ease, and 24-h calf survival were evaluated in a four-breed diallel of Simmental (S), Limousin (L), Polled Hereford (H) and Brahman (B) beef cattle in five calf crops. Limousin dams tended to have the highest calving and weaning rates because they were able to have heavier calves with less calving difficulty and higher survival rates. Brahman-sired calves were the heaviest at birth (P less than .05) and B dams produced the lightest calves (P less than .001). Lower birth weights tended to be the limiting factor on survival of these calves. A linear comparison among means to evaluate purebred, additive, maternal and specific combining ability effects showed most of the reduction in birth weight from B dams was due to maternal effects. Breed of dam accounted for a higher proportion of variation in calving ease than did sire breed. Simmental sires had significantly heavier calves at birth and S and H dams tended to have more calving difficulty and lower survival rates. Heterosis for these traits was generally not significant. Correlations were generally positive and significant for birth weight and calving ease, but were more variable for birth weight and survival. Linear regressions of calving ease on birth weight both within years and within dam-breed-year subclasses were very similar in that the association of these two traits was reduced as dam age increased.

    Braham-Hereford F1 dams have been used to evaluate the influence of grazing pressure on forage attributes and animal performance at the Texas A&M University Agricultural Research Center at Overton. Data for this study were compiled from 1,909 records of Simmental-sired calves born to Braham-Hereford F1 cows from 1975 to 1990. Birth weight and weaning weight were analyzed independently to estimate the influence of year, season of birth, dam age, weaning age, and sex of calf. The effect of stocking rate as represented by levels of forage availability on weaning weights and subsequent birth weights was measured. Within the fall and winter calving seasons, lactating dams grazing at a high stocking rate produced calves with the lowest subsequent birth weights. Lactating dams assigned to creep-fed treatments had calves with the heaviest subsequent birth weights. Although dams that were less than 3.5 yr of age had calves with the lightest birth weights, there was no apparent decline in birth weight of calves from dams 12 to 17 yr old. Year, sex of calf, age of dam, stocking rate, season of birth, age at weaning, and birth weight were significant factors affecting weaning weight (P less than .01). Fall-born calves grazing cool-season annual pastures were heavier at weaning (267.6 kg) than either winter- (252.0 kg) or spring-born calves (240.9 kg). A stocking rate x season-of-birth interaction was observed for birth weight and weaning weight (P less than .05). Differences in weaning weight from low- vs high-stocked pastures were greater for fall-born calves (61.6 kg) than for winter-born calves (48.7).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1506293

These differences offset each other, thus 57% of both populations remain in their first marriage until censoring. The interpretation may be that since twins have a partner from birth, they do not have the same need for marriage as singletons...

    Full Text Available Objective: Ninety percent of neonates pass the transition from fetal life to outside uterus successfully, and only 1% needs intensive support for survival. The quantity of oxygen saturation immediately after birth shows the need for resuscitation immediately after birth. The present research was carried out with the objective of comparing saturation rate of arterial blood hypoxia in neonates born with normal vaginal delivery and cesarean method. Materials and Methods: 220 neonates born with elective cesarean section and normal delivery were studied in an analytical-descriptive study. Demographic questionnaire was completed. Then a pulse oxymeter with its sensor fixed on the right wrist of the neonates was used. Heart rate was recorded and the level of oxygen saturation (SaO2 under 90% was considered as hypoxia. To compare the quantitative and qualitative variable between the two groups, paired t test and chi-square test was used, respectively. Pearson correlation test was used to study the correlation between the variables. Results: The age range of mothers was 16-38 years. The mothers’ average age, gestational age and neonates’ weight were not significantly different between groups. The average SaO2 in minutes 1, 3 and 5 was 72%, 81% and 89%, respectively in vaginal delivery, which showed a significant difference compared to cesarean neonates with average of 65%, 75% and 83%, respectively. No significant difference was observed after10 minutes. Also there were not significant statistical correlation between mothers age, number of pregnancies, sex and weight of neonate with SaO2 of arterial blood after 1, 3, 5 and 10 minutes after birth. Conclusion: With respect to the results of the present research SaO2 was higher in neonates of vaginal delivery in comparison to cesarean neonates. Encouraging mothers to delivery vaginally and also using aid-oxygen is proposed for the cesarean neonates at birth.

Six out of 11 DS-low rats during pregnancy produced pups while the rats fed a high-salt diet all delivered pups (P<0.025. The pup survival rate was 67% for high-salt mothers during mating and 54% for mothers on a low-salt diet. The pup survival rate was 95% for mothers on a high-salt diet during pregnancy and 64% for mothers on a low-salt diet (P<0.0001. Seven out of 8 DS-regular rats during mating delivered 59 neonates. However, 66% of the neonates survived. A low-salt diet during mating or pregnancy lowers birth rate and the neonates from low-salt mothers during pregnancy were more likely to die than those from high-salt mothers.

    Full Text Available The aim of this study was to assess the validity of the last menstrual period (LMP estimate in determining pre and post-term birth rates, in a prenatal cohort from two Brazilian cities, São Luís and Ribeirão Preto. Pregnant women with a single fetus and less than 20 weeks' gestation by obstetric ultrasonography who received prenatal care in 2010 and 2011 were included. The LMP was obtained on two occasions (at 22-25 weeks gestation and after birth. The sensitivity of LMP obtained prenatally to estimate the preterm birth rate was 65.6% in São Luís and 78.7% in Ribeirão Preto and the positive predictive value was 57.3% in São Luís and 73.3% in Ribeirão Preto. LMP errors in identifying preterm birth were lower in the more developed city, Ribeirão Preto. The sensitivity and positive predictive value of LMP for the estimate of the post-term birth rate was very low and tended to overestimate it. LMP can be used with some errors to identify the preterm birth rate when obstetric ultrasonography is not available, but is not suitable for predicting post-term birth.

    Studies report variable factors associated with dog and cat surpluses in the United States. Estimates of cat and dog birth and death rates help understand the problem. This study collected data through a commercial survey company, distributing questionnaires to 7,399 cat- and dog-owning households (HHs) in 1996. The study used an unequal probability sampling plan and reported estimates of means and variances as weighted averages. The study used estimates of HHs and companion animals for national projections. More than 9 million owned cats and dogs died during 1996-yielding crude death rates of 8.3 cat deaths/100 cats in HHs and 7.9 dog deaths/100 dogs in HHs. The study reported twice as many kitten as puppy litters, with an average litter size of 5.73 and 7.57, respectively. The study reported data on planned versus unplanned litters, reasons caregivers did not spay females, disposition of litters, and sources of animals added to HHs. These first national estimates indicate the magnitude of, and reasons for, animals leaving HHs. The crude birth rate was estimated to be 11.2 kittens/100 cats in HHs and 11.4 puppies/100 dogs in HHs.

    "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." PMID:12285449

    Full Text Available Although little is known about the role of the cystic fibrosis transmembrane regulator (CFTR gene in reproductive physiology, numerous variants in this gene have been implicated in etiology of male infertility due to congenital bilateral absence of the vas deferens (CBAVD. Here, we studied the fertility effects of three CBAVD-associated CFTR polymorphisms, the (TGm and polyT repeat polymorphisms in intron 8 and Met470Val in exon 10, in healthy men of European descent. Homozygosity for the Met470 allele was associated with lower birth rates, defined as the number of births per year of marriage (P = 0.0029. The Met470Val locus explained 4.36% of the phenotypic variance in birth rate, and men homozygous for the Met470 allele had 0.56 fewer children on average compared to Val470 carrier men. The derived Val470 allele occurs at high frequencies in non-African populations (allele frequency = 0.51 in HapMap CEU, whereas it is very rare in African population (Fst = 0.43 between HapMap CEU and YRI. In addition, haplotypes bearing Val470 show a lack of genetic diversity and are thus longer than haplotypes bearing Met470 (measured by an integrated haplotype score [iHS] of -1.93 in HapMap CEU. The fraction of SNPs in the HapMap Phase2 data set with more extreme Fst and iHS measures is 0.003, consistent with a selective sweep outside of Africa. The fertility advantage conferred by Val470 relative to Met470 may provide a selective mechanism for these population genetic observations.

    2015-01-01

    Background Prenatal exposure to perfluoroalkyl substances (PFAS) has been associated with lower birth weight in epidemiologic studies. This association could be attributable to glomerular filtration rate (GFR), which is related to PFAS concentration and birth weight. Objectives We used a physiologically based pharmacokinetic (PBPK) model of pregnancy to assess how much of the PFAS–birth weight association observed in epidemiologic studies might be attributable to GFR. Methods We modified a PBPK model to reflect the association of GFR with birth weight (estimated from three studies of GFR and birth weight) and used it to simulate PFAS concentrations in maternal and cord plasma. The model was run 250,000 times, with variation in parameters, to simulate a population. Simulated data were analyzed to evaluate the association between PFAS levels and birth weight due to GFR. We compared simulated estimates with those from a meta-analysis of epidemiologic data. Results The reduction in birth weight for each 1-ng/mL increase in simulated cord plasma for perfluorooctane sulfonate (PFOS) was 2.72 g (95% CI: –3.40, –2.04), and for perfluorooctanoic acid (PFOA) was 7.13 g (95% CI: –8.46, –5.80); results based on maternal plasma at term were similar. Results were sensitive to variations in PFAS level distributions and the strength of the GFR–birth weight association. In comparison, our meta-analysis of epidemiologic studies suggested that each 1-ng/mL increase in prenatal PFOS and PFOA levels was associated with 5.00 g (95% CI: –21.66, –7.78) and 14.72 g (95% CI: –8.92, –1.09) reductions in birth weight, respectively. Conclusion Results of our simulations suggest that a substantial proportion of the association between prenatal PFAS and birth weight may be attributable to confounding by GFR and that confounding by GFR may be more important in studies with sample collection later in pregnancy.

    We propose a conceptual model to explain the variation in species richness in local communities and in build-up of regional species pools over time. The idea is that the opportunity for new species to enter a community (its invasibility) determines the present richness of that community as well as the long-term build-up of a species pool by speciation and migration. We propose that a community's invasibility is determined by the turnover rate of reproductive genets in the community, which...

  15. Midwife-led Care Model for Reducing Caesarean Rate: A Novel Concept for Worldwide Birth units where Standard Obstetric Care Still Dominates

    Directory of Open Access Journals (Sweden)

    Hong Zhou

    2012-01-01

    Full Text Available Caesarean rate has been increasing year by year in China and other countries in the world. In fact, caesarean section is associated with increased risk of maternal mortality and serious foetal pulmonary morbidity. To reduce caesarean rate, obstetricians in physician-based birth units get used to take early intervention for any delay in labour progress that could cause dystocia. However, standard obstetric care enhanced by obstetric power has not consistently been shown to reduce rate of caesarean delivery. Other than physician-based model, midwife-led model of care is aiming to promote normal birth by use of midwives’ skills as well as continuous support rather than augmentation of labour through excessive medical treatment. Midwife-led care model is novel to worldwide birth units where standard obstetric care still dominates. It has made some headway in efforts to reduce caesarean rate. The fact that standard obstetric care of childbirth have not consistently reduced rate of caesarean delivery encourages us for creating the hypotheses that midwife-led care model satisfying puerpera with care and support could minimise unnecessary obstetric intervention and facilitate vaginal birth, and finally reduces caesarean rate. This hypothesis, if confirmed, might have the potential to be disseminated elsewhere in the world, where most women still take standard obstetric care. Moreover, it has political implications for the national health-care policymaking.

    Full Text Available Health and development are intricately related. Although India has made significant progress in the last few decades in the health sector and overall growth in GDP, there are still large regional differences in both health and development. The main objective of this paper is to develop techniques for the prediction of health indicators for all the districts of India and examine the correlations between health and development. The level of electrification and district domestic product (DDP are considered as two fundamental indicators of development in this research. These data, along with health metrics and the information from two nighttime satellite images, were used to propose the models. These successfully predicted the health indicators with less than a 7%–10% error. The chosen health metrics, such as crude birth rate (CBR and maternal mortality rate (MMR, were mapped for the whole country at the district level. These metrics showed very strong correlation with development indicators (correlation coefficients ranging from 0.92 to 0.99 at the 99% confidence interval. This is the first attempt to use Visible Infrared Imaging Radiometer Suite (VIIRS (satellite imagery in a socio-economic study. This paper endorses the observation that areas with a higher DDP and level of electrification have overall better health conditions.

  18. Preimplantation Genetic Diagnosis and Natural Conception: A Comparison of Live Birth Rates in Patients with Recurrent Pregnancy Loss Associated with Translocation.

    Directory of Open Access Journals (Sweden)

    Shinichiro Ikuma

    Full Text Available Established causes of recurrent pregnancy loss (RPL include antiphospholipid syndrome, uterine anomalies, parental chromosomal abnormalities, particularly translocations, and abnormal embryonic karyotypes. The number of centers performing preimplantation genetic diagnosis (PGD for patients with translocations has steadily increased worldwide. The live birth rate with PGD was reported to be 27-54%. The live birth rate with natural conception was reported to be 37-63% on the first trial and 65-83% cumulatively. To date, however, there has been no cohort study comparing age and the number of previous miscarriages in matched patients undergoing or not undergoing PGD. Thus, we compared the live birth rate of patients with RPL associated with a translocation undergoing PGD with that of patients who chose natural conception.After genetic counseling, 52 patients who desired natural conception and 37 patients who chose PGD were matched for age and number of previous miscarriages and these comprised the subjects of our study. PGD was performed by means of fluorescence in situ hybridization analysis. The live birth rates on the first PGD trial and the first natural pregnancy after ascertainment of the carrier status were 37.8% and 53.8%, respectively (odds ratio 0.52, 95% confidence interval 0.22-1.23. Cumulative live birth rates were 67.6% and 65.4%, respectively, in the groups undergoing and not undergoing PGD. The time required to become pregnancy was similar in both groups. PGD was found to reduce the miscarriage rate significantly. The prevalence of twin pregnancies was significantly higher in the PGD group. The cost of PGD was $7,956 U.S. per patient.While PGD significantly prevented further miscarriages, there was no difference in the live birth rate. Couples should be fully informed of the similarity in the live birth rate, the similarity in time to become pregnancy, the advantages of PGD, such as the reduction in the miscarriage rate, as well as

  3. A new approach of nonparametric estimation of incidence and lifetime risk based on birth rates and incident events

    Directory of Open Access Journals (Sweden)

    2007-12-01

    Full Text Available Abstract Background Incidence and lifetime risk of diabetes are important public health measures. Traditionally, nonparametric estimates are obtained from survey data by means of a Nelson-Aalen estimator which requires data information on both incident events and risk sets from the entire cohort. Such data information is rarely available in real studies. Methods We compare two different approaches for obtaining nonparametric estimates of age-specific incidence and lifetime risk with emphasis on required assumptions. The first and novel approach only considers incident cases occurring within a fixed time window–we have termed this cohort-of-cases data–which is linked explicitly to the birth process in the past. The second approach is the usual Nelson-Aalen estimate which requires knowledge on observed time at risk for the entire cohort and their incident events. Both approaches are used on data on anti-diabetic medications obtained from Odense Pharmacoepidemiological Database, which covers a population of approximately 470,000 over the period 1993–2003. For both methods we investigate if and how incidence rates can be projected. Results Both the new and standard method yield similar sigmoidal shaped estimates of the cumulative distribution function of age-specific incidence. The Nelson-Aalen estimator gives somewhat higher estimates of lifetime risk (15.65% (15.14%; 16.16% for females, and 17.91% (17.38%; 18.44% for males than the estimate based on cohort-of-cases data (13.77% (13.74%; 13.81% for females, 15.61% (15.58%; 15.65% for males. Accordingly the projected incidence rates are higher based on the Nelson-Aalen estimate–also too high when compared to observed rates. In contrast, the cohort-of-cases approach gives projections that fit observed rates better. Conclusion The developed methodology for analysis of cohort-of-cases data has potential to become a cost-effective alternative to a traditional survey based study of incidence. To

    2016-01-01

    INTRODUCTION This study aimed to determine whether patient loads, infant status on admission and treatment interventions were significantly associated with inter-institutional variations in sepsis rates in very-low-birth-weight (VLBW) infants in the Malaysian National Neonatal Registry (MNNR). METHODS This was a retrospective study of 3,880 VLBW (≤ 1,500 g) infants admitted to 34 neonatal intensive care units (NICUs) in the MNNR. Sepsis was diagnosed in symptomatic infants with positive blood culture. RESULTS Sepsis developed in 623 (16.1%) infants; 61 (9.8%) had early-onset sepsis (EOS) and 562 (90.2%) had late-onset sepsis (LOS). The median EOS rate of all NICUs was 1.0% (interquartile range [IQR] 0%, 2.0%). Compared with NICUs reporting no EOS (n = 14), NICUs reporting EOS (n = 20) had significantly higher patient loads (total live births, admissions, VLBW infants, outborns); more mothers with a history of abortions, and antenatal steroids and intrapartum antibiotic use; more infants requiring resuscitation procedures at birth; higher rates of surfactant therapy, pneumonia and insertion of central venous catheters. The median LOS rate of all NICUs was 14.5% (IQR 7.8%, 19.2%). Compared with NICUs with LOS rates below the first quartile (n = 8), those above the third quartile (n = 8) used less intrapartum antibiotics, and had significantly bigger and more mature infants, more outborns, as well as a higher number of sick infants requiring ventilator support and total parenteral nutrition. CONCLUSION Patient loads, resuscitation at birth, status of infants on admission and treatment interventions were significantly associated with inter-institutional variations in sepsis.

    Objective: To compare the obstetric outcome in terms of risk of low birth weight, preterm delivery, cesarean section rate and anemia in primigravid adolescents and older primigravida. Study Design: Cohort study. Place and Duration of Study: Department of Obstetrics and Gynaecology, Sir Ganga Ram Hospital, Lahore, from July to December 2012. Methodology: Three hundred primigravid women presenting to department of obstetrics and gynecology of Sir Ganga Ram Hospital, Lahore, having live singleton pregnancy, including 150 adolescents (A/sup 2/ 19 years) and 150 adults (A/sup 3/ 20 years) were studied. Obstetric outcome in terms of gestational age at delivery, infant's birth weight, presence of anemia and cesarean section rate was compared between two groups. Results were analyzed using Statistical Package for Social Sciences (SPSS) version 16. Chi-square test was applied with 0.05 as level of significance. Results: The mean age of adolescent subjects was 17.3 + 1.5 years and of adults 25.6 + 3.4 years. Mean gestational age at delivery was similar in two groups (39.2 weeks and 39.4 weeks, p = 0.37). Adolescents were more likely to have a preterm delivery (11.2% vs. 4.9%, p = 0.04) and low birth weight infants (19.3% vs. 8.2%, p = 0.005) than adults. Adolescents were more likely to be anemic (46% vs. 32%, p = 0.01) than adults. However, cesarean section rate was not statistically different between two groups. Conclusion: This study showed that primiparous adolescents have significantly higher risk of adverse pregnancy outcomes such as preterm delivery, low birth weight infants and anemia as compared to adult primiparas.

    Providing hepatitis B vaccine to all neonates within 24 hours of birth (Timely Birth Dose, TBD) is the key preventative measure to control perinatal hepatitis B virus infection. Previous Chinese studies of TBD only differentiated between migrant and non-migrant (local-born generation-LG) children. Our study is the first to stratify migrants in Beijing into first generation migrants (FGM) and second generation migrants (SGM). Based on a questionnaire survey of 2682 people in 3 Beijing villages, we identified 283 children aged 0-15 years, from 246 households, who were eligible for a TBD. Multinomial logistic regression and statistical analyses were used to examine factors explaining TBD rates for LG, FGM and SGM children. Surprisingly, the TBD for LG Beijing children was not significantly different from migrant children. But after stratifying migrant children into FGM and SGM, revealed significant TBD differences were revealed across LG, FGM and SGM according to domicile (p-value FGM children, SGM had a significantly poorer TBD rate (Fisher exact test of chi-square = 0.013). We identified SGM as a special risk group; proposed Hukou reform to improve SGM TBD; and called for Beijing health authorities to match TBD rates in other provinces, especially by improving practices by health authorities and knowledge of parents.

    Many of us are in the business of improving birth. Some of us are decades into our journeys of midwifery, whilst others are fresh students aspiring to give our best in this new profession. This article looks at ways to redeem birth from two aspects: for the mother; and for the midwife. I work in an international community in a developing country, in a privatised system. Although different from the UK, birth is birth. Women, their families and midwives will be able to relate to similar experiences. Ultimately my goals are likely to be the same as those in other parts of the world. I address issues of the workplaces in which we operate, the role of midwives in redeeming birth outcomes, and how we may better serve women and each other. PMID:27295755

    Fetal heart rate (FHR) sampling rate used on the bedside is equal or less than 4 Hz. Current FHR analysis methods fail to detect incipient fetal acidemia. In a fetal sheep model of human labour we showed that FHR sampling rates near 1000 Hz are needed to detect fetal acidemia. Trans-abdominal fetal ECG (t-a fECG) sampling FHR at 900 Hz combined with a complex signals bioinformatics approach showed promise in a human cohort. Here we validate this finding in a retrospective human cohort study by comparing the performance of the same bioinformatics approach to predict pH and BE at birth in the cohorts with FHR sampled either at 4 Hz or at 900 Hz.The 4 Hz FHR recording data sets consisted of the open access intrapartum CTG data base with n = 552 subjects used to develop the predictive model and another cohort of prospectively recruited n = 11 labouring women to then validate it. 900 Hz FHR data set comprised two prospectively recruited t-a fECG cohorts of n = 60 and n = 23 subjects. Recruitment criteria were similar across the cohorts. We have determined the goodness of fit (R(2)) and root mean square error (RMSE) as the performance indicators of the model on each cohort.The clinical characteristics of all cohorts were similar (gestational age 280   ±   8 d; gender 50% male; birth body weight 3.5   ±   0.5 kg; pH and BE at birth 7.25   ±   0.1 and  -5.7   ±   3.4 mmol L(  -  1), respectively; 1' and 5' Apgar scores at birth 8.5   ±   1.4 and 9.4   ±   0.6, respectively). The 4 Hz FHR cohort rendered-for pH and BE-R(2) = 0.26 and 0.2 and RMSE = 0.087 and 3.44, respectively. This could not be confirmed in the validation cohort for neither pH nor BE prediction. The 900 Hz FHR cohort rendered-for pH and BE-R(2) = 0.9 and 0.77 and RMSE = 0.03 and 1.70, respectively, and the pH prediction was validated.In our model, lower FHR sampling rate increased the

    Iraq is suffering from depleted uranium (DU) pollution in many regions and the effects of this may harm public health through poisoning and increased incidence of various cancers and birth defects. DU is a known carcinogenic agent. About 1200 tonnes of ammunition were dropped on Iraq during the Gulf Wars of 1991 and 2003. As a result, contamination occurred in more than 350 sites in Iraq. Currently, Iraqis are facing about 140,000 cases of cancer, with 7000 to 8000 new ones registered each year. In Baghdad cancer incidences per 100,000 population have increased, just as they have also increased in Basra. The overall incidence of breast and lung cancer, Leukaemia and Lymphoma, has doubled even tripled. The situation in Mosul city is similar to other regions. Before the Gulf Wars Mosul had a higher rate of cancer, but the rate of cancer has further increased since the Gulf Wars. PMID:23729095

    Full Text Available Background: The aim of this study was to investigate the maternal, foetal and obstetric parameters surrounding twin pregnancies. An attempt was made to find out the perinatal mortality and morbidity rates of twin births and to determine the underlying factors responsible for the increase in these rates. Methods: A one year observational study was done at Daga hospital Nagpur, which is a referral maternity hospital receiving a large number of antenatal patients daily. Perinatal mortality and morbidity rates, gestational age at delivery, birth weight, route of delivery, and caesarean section rates were analysed. Results: The commonest presentation in our study vertex/vertex presentation (62%. A large percentage of twins in our study had a normal delivery. 37% women had caesarean section. In our study nearly 17% of the neonates had birth weights <1.5 kg. In 51 % women the first baby had more birth weight than the second twin. Among the 95 twin births (190 twins studied, we had one discordant twins and one conjoined twins. Conclusions: Twin pregnancies are high risk pregnancies with more obstetrical complications compared to singleton pregnancies. Twin pregnancies have higher perinatal mortality and morbidity rates especially before 34 weeks of gestation. Hence deliveries should be performed in referral centres with competent NICUs.

    The effects of pituitary suppression with one-third depot of long-acting gonadotropin-releasing hormone (GnRH) agonist in GnRH agonist long protocol for in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) were investigated. A retrospective cohort study was performed on 3186 cycles undergoing IVF/ICSI with GnRH agonist long protocol in a university-affiliated infertility center. The pituitary was suppressed with depot triptorelin of 1.25 mg or 1.875 mg. There was no significant difference in live birth rate between 1.25 mg triptorelin group and 1.875 mg triptorelin group (41.2% vs. 43.7%). The mean luteinizing hormone (LH) level on follicle-stimulating hormone (FSH) starting day was significantly higher in 1.25 mg triptorelin group. The mean LH level on the day of human chorionic gonadotrophin (hCG) administration was slightly but statistically higher in 1.25 mg triptorelin group. There was no significant difference in the total FSH dose between the two groups. The number of retrieved oocytes was slightly but statistically less in 1.25 mg triptorelin group than in 1.875 mg triptorelin group (12.90±5.82 vs. 13.52±6.97). There was no significant difference in clinical pregnancy rate between the two groups (50.5% vs. 54.5%). It was suggested that one-third depot triptorelin can achieve satisfactory pituitary suppression and produce good live birth rates in a long protocol for IVF/ICSI. PMID:27072965

    The experiment was conducted to investigate the effect of the different insemination duration on conception rate and birth rate after artificial insemination in Landrace White gilts. According to the differences of estrus time,75 Landrace White gilts were divided into five groups with group A,group B,group C,group D and group E,15 gilts of each group. Each gilt insemination duration in each group was 2~3 min,3~4 min,4~5 min,5~6 min and 6~7 min,each gilt was inseminated three times. The conception rates and birth rates of each group were calculated. The results indicated that insemination duration of 4~5 min or more(including 4~5 min),the conception rates and birth rates had no differences among the Landrace gilts group C,group D and group E. The conception rates and birth rates of group C,group D and group E were significantly higher than those of group A and group B whose insemination duration less than 4~5 min. The tests showed that the gilts could obtain higher conception rate and birth rate when the insemination duration was controlled 4~5 min,which was the best insemination duration.%为探讨不同输精持续时间对长白后备母猪受胎率和产仔数的影响,选择大白后备母猪75头,根据发情时间的不同分为A组、B组、C组、D组和E组,每组15头。每组母猪的输精持续时间分别为2~3、3~4、4~5、5~6、6~7 min,每头母猪输精3次。配种后统一管理,统计每组母猪的受胎率和产仔数。结果显示,输精持续时间在4~5 min以上(含4~5 min),长白后备母猪C组、D组和E组3组之间的受胎率和产仔数均差异不明显,并且C组、D组、E组之间的受胎率和产仔数明显高于输精持续时间低于4~5 min的A组和B组。试验表明,输精持续时间控制在4~5 min时,后备母猪能够获得较高的受胎率和产仔率,为最佳的输精持续时间。

    Objective: To assess the effect of melatonin (MT) at different seasons of the year on sperm motility, viability, total sperm abnormality, acrosomal membrane, plasma membrane and nuclear integrity, antioxidant profiles such as superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and total antioxidant capacity (TAC), enzymatic profiles such as aspartate amino transaminase (AST), alanine amino transaminase (ALT) and biochemical profiles such as malondialdehyde (MDA) production. Methods: Total numbers of 80 ejaculates (20 ejaculates in each season) were collected twice a week from mithun bulls and semen was split into five equal aliquots, diluted with the tris egg yolk citrate (TEYC) extender. Group 1:semen without additives (control), group 2 to group 5:semen was diluted with 1 mM, 2 mM, 3 mM, and 4 mM of melatonin, respectively. These seminal parameters, antioxidant, enzymatic and biochemical profiles were assessed at liquid storage of mithun semen (5 ℃). Simultaneously, retrospective study was conducted on birth rate of calf at different seasons from 2002 to 2012 from farm birth register of mithun farm. Results: Inclusion of melatonin into diluent resulted in significant (P<0.05) decrease in percentages of dead spermatozoa, abnormal spermatozoa and acrosomal abnormalities at different seasons of the year as compared with control group. Additionally, spring season has highest seminal and antioxidant profiles followed by autumn and winter season, whereas lower values were observed in ejaculates collected from summer season. Similarly retrospective study revealed that highest birth rate was in winter followed by autumn, spring and summer season and breeding was occurred in spring, winter, summer and autumn season, respectively with gestation period of 270- 290 days. Conclusions:The result of present study indicates that the melatonin protects seminal and antioxidant profiles varied in different seasons, semen quality also varied from different seasons and

    Full Text Available Pregnancy causes large physiologic changes in most body systems and these changes may lead to ease or harden examining some events. The purpose of this study is to define the rate of risk in pregnant women and the results in mother and fetus and also to define the risk rate of pregnancy in pregnant women and its effect on parameters after birth in patients of Educational and Medical center of Gorgan, Dezyani. This case - control study was performed in Educational and Medical Center Dezyany, of Golestan University of Medical Sciences in 1390. In this study, 1266 pregnant women were enrolled of which 804 cases (63.5% according to the criteria for scoring in the questionnaire with a score greater than or equal to 7 were considered as high risk pregnancies (case group, 462 patients (36.5% were considered as low-risk pregnancies (control group. Parameters after the birth and pregnancy results such as delivery type, infant difficulties, mother health after labor were compared and analyzed by T-test and ANOVA in both groups. About the history of infertility almost 80% of the people who had a 2-year history of infertility were in high-risk group and the difference was significant. (P = 0.02 About the history of abortion also almost 90% of the people who had a 2-year history of abortion were in high-risk group and the difference was significant. (P<0.05 Post-term infant was found in 77 cases that were entirely in high-risk group. This difference was statistically significant (P<0.05. According to results and comparing them to other studies we can conclude that pregnant mothers who have pregnancy difficulties history such as history of abortion or infertility, visits during pregnancy should be paid attention and warn them about the risk of not being visited and timely pursuits.

Methods: A retrospective study done by collecting the data from parturition register from Jan 2008 to Dec 2011 (4yrs from Cheluvamba Hospital attached to Mysore Medical College and Research Institute. Total number of the live births, still births, and abortions> 20 wks were collected. Details of multiple births such as maternal age, gestational age, sex & birth weight of the babies, U/S reports and congenital anomalies (CA were noted. Results: The total number of singleton births were 48700 and number of babies who had congenital malformations were 235 (48.25/10,000 births.Total number of multiple births were 579 including 10 triplets and number of babies who had CA were 11 (189.98/10,000 births, P<0.0001. In the present study sex of the babies were noted in all multiple births and zygosity could not be recorded. Among 579 multiple births 404 were of the Same Sex (SS and 165 were of Opposite Sex (OS in twins and 6 were of the same sex and 4 were of opposite sex in triplets. According to Weinberg formula 50% of same sex (SS twins are monozygotic and 50% are dizygotic twins. Among the 11 babies with CA, 4 monozygotic twins had anomalies related to twinning such as Acardia with TRAP sequence (3 twins, and Thoracophagus (1 twin.5 babies had CNS anomalies, 1 with cystic hygroma, 1 baby with multiple system affected. Conclusion: The incidence of birth defects is more in multiple births and especially in monozygotic twins. In the present days increase in twinning rate due to advanced maternal age, hereditary factors and use of ovulation inducing drugs, which results in premature and low birth wt babies associated with poor lung maturity.

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.

    Full Text Available BACKGROUND: Poor self-rated health (SRH has been connected to immunological changes, and pregnancy complications have been suggested in the etiology of autoimmune diseases including inflammatory bowel disease (IBD. We evaluated the impact of self-rated pre-pregnancy health and pregnancy course, hyperemesis, gestational hypertension, and preeclampsia on risk of IBD. METHODS: Information was collected by questionnaires from The Danish National Birth Cohort (enrolment 1996-2002 at 16(th and 30(th week of pregnancy and 6 months postpartum. A total of 55,699 women were followed from childbirth until development of IBD (using validated National Hospital Discharge Register diagnoses, emigration, death, or end of follow-up, 31(st of October, 2011. Hazard ratios (HR with 95% confidence intervals (CI were calculated using Cox proportional hazards models adjusting for age and evaluating pre-pregnancy BMI, parity, alcohol and tobacco consumption, and socio-occupational status as potential confounders. RESULTS: Risk of IBD increased with decreasing level of self-rated pre-pregnancy health (p = 0.002 and was elevated in women with poor self-rated pregnancy course (HR, 1.61, 95% CI 1.22-2.12. Associations persisted for more than 5 years postpartum. Hyperemesis and preeclampsia were not significantly associated with risk of IBD. CONCLUSIONS: This is the first prospective observational study to suggest that poor self-rated health--in general and in relation to pregnancy--is associated with increased risk of IBD even in the long term though results needs further confirmation. Symptoms of specific pregnancy complications were, on the other hand, not significantly associated with risk of IBD.

    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.

    Full Text Available OBJECTIVE: To evaluate ovarian response and cumulative live birth rate of women undergoing in-vitro fertilization (IVF treatment who had discordant baseline serum anti-Mullerian hormone (AMH level and antral follicle count (AFC. METHODS: This is a retrospective cohort study on 1,046 women undergoing the first IVF cycle in Queen Mary Hospital, Hong Kong. Subjects receiving standard IVF treatment with the GnRH agonist long protocol were classified according to their quartiles of baseline AMH and AFC measurements after GnRH agonist down-regulation and before commencing ovarian stimulation. The number of retrieved oocytes, ovarian sensitivity index (OSI and cumulative live-birth rate for each classification category were compared. RESULTS: Among our studied subjects, 32.2% were discordant in their AMH and AFC quartiles. Among them, those having higher AMH within the same AFC quartile had higher number of retrieved oocytes and cumulative live-birth rate. Subjects discordant in AMH and AFC had intermediate OSI which differed significantly compared to those concordant in AMH and AFC on either end. OSI of those discordant in AMH and AFC did not differ significantly whether either AMH or AFC quartile was higher than the other. CONCLUSIONS: When AMH and AFC are discordant, the ovarian responsiveness is intermediate between that when both are concordant on either end. Women having higher AMH within the same AFC quartile had higher number of retrieved oocytes and cumulative live-birth rate.

    1999-01-01

    Advocacy for homebirth is based on the strong assumption that birthing is a physiological process and does not require medical interventions unless things turn "wrong." Let us assume that something might always go wrong, for instance during Clara's birth when the placenta was still retained after three hours. What needs to be done? The moment the midwife entered the house she was endowed with a responsibility for any problem caused by her failure to give proper guidance. With this weight on her shoulder, and according to her training and experience, there was no other way for her than to suggest an intervention regarding the placenta. The two midwives, B, and C., might not agree on risk estimations, the nature of the intervention, whether it should be performed at home or in a hospital. The estimation of abnormalities, evaluation of risks and the procedures with which to handle them are the main practical difference between classic obstetrics and non-interventionist midwifery--by analogy, between allopathy and naturopathy. The rest (positive thinking) is basically literature. A delivery will not remain normal just because we decide it "must" be physiological. Dr. Barua, a professor of obstetrics in Pondicherry, pointed out that normal deliveries are rare--fewer than 10 percent in South India. What we have instead is either pathological or "natural" deliveries in which regenerative processes take care of abnormal situations. Unless she has developed sensitive hands, a birth assistant or midwife must rely on monitoring procedures to evaluate deviations from the normal process. Even with the greatest care, these procedures are intrusive in that they disconnect the parturient from her own sensations. While successful unattended homebirth stories emphasise the extraordinary power and sensitivity of a birthing woman, the whole dream seems to collapse in abnormal or pathological cases. It would have collapsed for Sonia as well, had she not discarded negative suggestions

    2015-01-01

    While the number of women in developed countries who plan a home birth is low, the number has increased over the past decade in the US, and there is evidence that more women would choose this option if it were readily available. Rates of planned home birth range from 0.1% in Sweden to 20% in the Netherlands, where home birth has always been an integrated part of the maternity system. Benefits of planned home birth include lower rates of maternal morbidity, such as postpartum hemorrhage, and perineal lacerations, and lower rates of interventions such as episiotomy, instrumental vaginal birth, and cesarean birth. Women who have a planned home birth have high rates of satisfaction related to home being a more comfortable environment and feeling more in control of the experience. While maternal outcomes related to planned birth at home have been consistently positive within the literature, reported neonatal outcomes during planned home birth are more variable. While the majority of investigations of planned home birth compared with hospital birth have found no difference in intrapartum fetal deaths, neonatal deaths, low Apgar scores, or admission to the neonatal intensive care unit, there have been reports in the US, as well as a meta-analysis, that indicated more adverse neonatal outcomes associated with home birth. There are multiple challenges associated with research designs focused on planned home birth, in part because conducting randomized controlled trials is not feasible. This report will review current research studies published between 2004 and 2014 related to maternal and neonatal outcomes of planned home birth, and discuss strengths, limitations, and opportunities regarding planned home birth.

    Birth-death processes (BDPs) are continuous-time Markov chains that track the number of “particles” in a system over time. While widely used in population biology, genetics and ecology, statistical inference of the instantaneous particle birth and death rates remains largely limited to restrictive linear BDPs in which per-particle birth and death rates are constant. Researchers often observe the number of particles at discrete times, necessitating data augmentation procedures such as expectat...

    The standards of health and health care for a sample of 1265 Christchurch children during the period birth to three years were examined. There was a systematic tendency for levels of health care and morbidity to vary with the child's birth placement: in general adopted children had the best standard of health care and the lowest rates of morbidity; children who entered single parent families at birth had the poorest standards of health care and the highest rates of morbidity. Statistical control for family social background including maternal age, education, ethnic status, family size and changes of residence tended to reduce the size of the observed differences. However, even when the results were controlled for these factors children in single parent families still has depressed levels of preventive health care and higher rates of hospital admission. Possible explanations of the differences are discussed. PMID:6944632

    2016-01-01

    Thirty years ago seems like yesterday: a time of immense socioeconomic changes, explosion of an "Internet" computer concept, and identification of human immunodeficiency virus. Like all events of the past, transformations in obstetrics developed over time. Cesarean birth can be better understood in a broader context when one considers how the art of obstetric practice has evolved. Cesarean birth progressed from delivering a fetus perimortem or postmortem to a time of operative births that simultaneously juggle a woman's safety, satisfaction, and freedom of choice concerning birth options. Thirty years of increasing cesarean birth rates have prompted government agencies, national organizations, state-level perinatal collaborative groups, and experts to address these rates and the impact on maternal-child health and healthcare systems. The purpose of this article is to explain cesarean birth's remarkable impact on obstetrics by reviewing key historical periods, current advances, and upcoming trends. PMID:27465462

Rates of planned home birth range from 0.1% in Sweden to 20% in the Netherlands, where home birth has always been an integrated part of the maternity system. Benefits of planned home birth include lower rates of maternal morbidity, such as postpartum hemorrhage, and perineal lacerations, and lower rates of interventions such as episiotomy, instrumental vaginal birth, and cesarean birth. Women who have a planned home birth have high rates of satisfaction related to home being a more comfortable environment and feeling more in control of the experience. While maternal outcomes related to planned birth at home have been consistently positive within the literature, reported neonatal outcomes during planned home birth are more variable.

    Birth defects are one of the leading causes of paediatric disability and mortality in developed and developing countries. Data on birth defects from population-based studies originating from developing countries are lacking. One of the objectives of this study was to determine the epidemiology of major birth defects in births during the perinatal period in Kinta district, Perak, Malaysia over a 14-month period, using a population-based birth defect register. There were 253 babies with major birth defects in 17,720 births, giving an incidence of 14.3/1000 births, a birth prevalence of 1 in 70. There were 80 babies with multiple birth defects and 173 with isolated birth defects. The exact syndromic diagnosis of the babies with multiple birth defects could not be identified in 18 (22.5%) babies. The main organ systems involved in the isolated birth defects were cardiovascular (13.8%), cleft lip and palate (11.9%), clubfeet (9.1%), central nervous system (CNS) (including neural tube defects) (7.9%), musculoskeletal (5.5%) and gastrointestinal systems (4.7%), and hydrops fetalis (4.3%). The babies with major birth defects were associated with lower birth weights, premature deliveries, higher Caesarean section rates, prolonged hospitalization and increased specialist care. Among the cohort of babies with major birth defects, the mortality rate was 25.2% during the perinatal period. Mothers with affected babies were associated with advanced maternal age, birth defects themselves or their relatives but not in their other offspring, and significantly higher rates of previous abortions. The consanguinity rate of 2.4% was twice that of the control population. It is concluded that a birth defects register is needed to monitor these developments and future interventional trials are needed to reduce birth defects in Malaysia. PMID:16096215

  1. Birth in Brazil: national survey into labour and birth

    2012-08-01

    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

  2. Specific-locus experiments show that female mice exposed near the time of birth to low-LET ionizing radiation exhibit both a low mutational response and a dose-rate effect

    International Nuclear Information System (INIS)

    Female mice were exposed to 300 R of 73-93 R/min X-radiation either as fetuses at 18.5d post conception (p.c.) or within 9h after birth. Combining the similar results from these 2 groups yielded a specific-locus mutation frequency of 9.4x10-8 mutation/locus/R, which is statistically significantly higher than the historical-control mutation frequency, but much lower than the rate obtained by irradiating mature and maturing oocytes in adults. Other females, exposed at 18.5 days p.c. to 300 R of 0.79 R/min γ-radiation, yielded a mutation frequency that was statistically significantly lower than the frequency at high dose rates. The low-dose-rate group also had markedly higher fertility. It appears that the doe-rate effect for mutations induced near the time of birth may be more pronounced than that reported for mature and maturing oocytes of adults. A hypothesis sometimes advanced to explain low mutation frequencies recovered from cell populations that experience considerable radiation-induced cell killing is that there is selection against mutant cells. The reason for the relatively low mutational response following acute irradiation in the experiments is unknown; however, the finding of a dose-rate effect in these oocytes in the presence of only minor radiation-induced cell killing (as judged from fertility) makes it seem unlikely that selection was responsible for the low mutational response following acute exposure. Had selection been an important factor, the mutation frequency should have increased when oocyte killing was markedly reduced. (author). 32 refs.; 5 figs.; 5 tabs

    Renato Passini

    Full Text Available BACKGROUND: Preterm birth rate is increasing and is currently a worldwide concern. The purpose of this study was to estimate the prevalence of preterm birth in a sample of health facilities in Brazil and to identify the main risk factors associated with spontaneous preterm births. METHODS AND FINDINGS: This was a multicentre cross sectional study on preterm births in 20 referral obstetric hospitals with a case-control component to identify factors associated with spontaneous preterm birth. Surveillance was implemented at all centres to identify preterm births. For eligible consenting women, data were collected through a post-delivery questionnaire completed with information from all mother-newborn medical records until death or discharge or at a maximum of 60 days post-delivery, whichever came first. The risk of spontaneous preterm birth was estimated with OR and 95%CI for several predictors. A non-conditional logistic regression analysis was then performed to identify independently associated factors. The overall prevalence of preterm birth was 12.3%. Among them, 64.6% were spontaneous and 35.4% therapeutic. In the case-control component, 2,682 spontaneous preterm births were compared to a sample of 1,146 term births. Multivariate analyses identified the following as risk factors for spontaneous preterm birth among women with at least one previous birth: a previous preterm birth (ORadj = 3.19, 2.30-4.43, multiple pregnancy (ORadj = 29.06, 8.43-100.2, cervical insufficiency (ORadj = 2.93, 1.07-8.05, foetal malformation (ORadj = 2.63, 1.43-4.85, polyhydramnios (ORadj = 2.30, 1.17-4.54, vaginal bleeding (ORadj = 2.16, 1.50-3.11, and previous abortion (ORadj = 1.39, 1.08-1.78. High BMI (ORadj = 0.94, 0.91-0.97 and weight gain during gestation (ORadj = 0.92, 0.89-0.95 were found to be protective factors. CONCLUSIONS: The preterm birth rate in these health facilities in Brazil is high and spontaneous preterm births

    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.

    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)

  6. The German Birth Order Register - order-specific data generated from perinatal statistics and statistics on out-of-hospital births 2001-2008

    OpenAIRE

    Michaela Kreyenfeld; Scholz, Rembrandt D.; Frederik Peters; Ines Wlosnewski

    2010-01-01

    Until 2008, Germany’s vital statistics did not include information on the biological order of each birth. This resulted in a dearth of important demographic indicators, such as the mean age at first birth and the level of childlessness. Researchers have tried to fill this gap by generating order-specific birth rates from survey data, and by combining survey data with vital statistics. This paper takes a different approach by using hospital statistics on births to generate birth order-specific...

  7. Are Hispanic Women Happier About Unintended Births?

    OpenAIRE

    2012-01-01

    Reducing unintended pregnancies – particularly among Hispanic and Black women, who have relatively high rates – is a key public health goal in the United States. However, descriptive literature has suggested that Hispanic women are happier about these pregnancies compared with White and Black women, which could mean that there is variation across groups in the consequences of the resulting births. The purpose of this study was to examine variations in happiness about unintended births by race...

  8. Recent increase in sex ratio at birth in Viet Nam

    OpenAIRE

    2009-01-01

    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 wom...

    In order to investigate the effect of ginseng on semen quality and birth rate of sika deer, 32 healthy male sika deer in breeding season were selected and randomly divided into 4 groups(T1 -T4 ), and each group included 8 sika deer. The sika deer were fed with the basal diet or the basal diet containing 0.4, 0.8, 1.6 g/kg ginseng, which were denoted as Group T1, T2, T3 and T4 respectively. Results showed that supplementation with ginseng could greatly improve (p<0.05) the semen volume and the sperm motility, resistance, density, survival time and survival index of the sika deer, and decrease the sperm abnormality significantly; while the semen pH in the sika deer had no significant change. Moreover, suppiementation with ginseng could also increase the success rate for semen collection and the birth rate of the sika deer. Group T3 showed the most visible changes in cloudy and oyster white sperm. Therefore, adding 0. 8 g/kg ginseng to the diet exhibited the most significant effects on improving the semen quality and birth rate, which was favorable to the breeding of sika deer.%为了考察人参对梅花鹿精液品质及产仔率的影响,将繁殖准备期的健康雄性梅花鹿32头随机分为4个处理(T1~T4),每个处理8头,T1~T4为基础精料中分别添加人参0、0.4、0.8、1.6g/kg.结果表明:日粮中添加人参,显著提高了梅花鹿的采精液量、精子活力、精子抗力、精子密度、精子存活时间、精子存活指数(P<0.05);显著降低了精子畸形率(P<0.05);对精液pH值的影响没有显著差异(P<0.05);提高了采精成功率和产仔率;精液云雾状T3处理组最明显,精液色泽均为乳白色.梅花鹿精料中添加人参0.8g/kg时,对提高梅花鹿精液品质和产仔率效果最好,有利于鹿的繁育.

  10. Employment opportunities and pre-marital births in Britain

    OpenAIRE

    Ermisch, John

    2000-01-01

    In 1999, nearly two-fifths of births in Britain were outside marriage. This study estimates the impact of employment opportunities in the local labour market on the probability that a childless never married woman has a birth outside marriage. It uses the unemployment rate in the travel-to-work area in which the woman lives as the indicator of employment opportunities. The estimates indicate poorer employment opportunities increase the pre-marital first birth rate and discourage union formation.

  13. The changing trends in live birth statistics in Korea, 1970 to 2010

    Directory of Open Access Journals (Sweden)

    Jae Woo Lim

    2011-11-01

    Full Text Available Although Korean population has been growing steadily during the past four decades, the nation is rapidly becoming an aging society because of its declining birth rate combined with an increasing life expectancy. In addition, Korea has one of the lowest fertility rates in the world due to fewer married couples, advanced maternal age, and falling birth rate. The prevalence of low birth weight infants and multiple births has been increased compared with the decrease in the birth rate. Moreover, the number of congenital anomalies is expected to increase due to the advanced maternal age. In addition, the number of interracial children is expected to increase due to the rise in the number of international marriages. However, the maternal education level is high, single-mother birth rate is low, and the gender imbalance has lessened. The number of overweight babies has been decreased, as more pregnant women are receiving adequate prenatal care. Compared to the Asian average birth weight, the average birth weight is the highest in Asia. Moreover, the rate of low birth weight infants is low, and infant mortality is similarly low across Asia. Using birth data from Statistics Korea and studies of birth outcomes in Korea and abroad, this study aimed to assess the changes in maternal and infant characteristics associated with birth outcomes during the past four decades and identify necessary information infrastructures to study countermeasures the decrease in birth rate and increase in low birth weight infants in Korea.

    2013-01-01

    Full Text Available Background: The rate of primary cesarean section (CS is on the rise. More and more women report with a history of a previous CS. A trial of vaginal delivery can save these women from the risk of repeat CS. Aims: The study was conducted to assess the safety and success rate of vaginal birth after CS (VBAC in selected cases of one previous lower segment CS (LSCS. Materials and Methods: The prospective observational study was carried out in a tertiary care teaching hospital over a period of two years. One hundred pregnant women with a history of one previous LSCS were enrolled in the study. Results: In the present study, 85% cases had a successful VBAC and 15% underwent a repeat emergency LSCS for failed trial of vaginal delivery. Cervical dilatation of more than 3 cm at the time of admission was a significant factor in favor of a successful VBAC. Birth weight of more than 3,000 g was associated with a lower success rate of VBAC. The incidence of scar dehiscence was 2% in the present study. There was no maternal or neonatal mortality. Conclusion: Trial of VBAC in selected cases has great importance in the present era of the rising rate of primary CS especially in rural areas.

    2013-01-01

    Full Text Available Secular trends in rates of low birth weight in Brazilian state capital cities were evaluated for the period 1996 to 2010 using joinpoint regression models. The rates were calculated using data from the Live Births Information System. Newborns weighing less than 500g were excluded. Only data for capital cities was included since under-registration of births in these cities is lower and new trends can be detected earlier. There was a significant increase in the rate of low birth weight in the Brazilian capitals of the North Region, Northeast Region, South Region and Southeast Region up to 2003/2004, stabilizing thereafter. In the capitals of the Center-west Region the rate increased throughout the whole study period. The rate of low birth weight was higher in the capitals of the more developed regions. The rate of multiple births increased significantly in all Brazilian capitals, while the stillbirth rate decreased and showed a negative correlation with the rate of low birth weight. The increase in the rate of low birth weight may be partially explained by the increase in multiple births, an increase in the birth of infants weighing 500 to 999g and by the reduction in the stillbirth rate.La tendencia secular de la tasa de bajo peso al nacer de 1996 a 2010 en las capitales brasileñas se evaluó utilizando modelos de regresión joinpoint.

    Birth month is broadly predictive of both under-five mortality rates and stunting throughout most of sub-Saharan Africa (SSA). Observed factors, such as mother's age at birth and educational status, are correlated with birth month but are not the main factors underlying the relationship between birth month and child health. Accounting for maternal selection via a fixed-effects model attenuates the relationship between birth month and health in many SSA countries. In the remaining countries, t...

    Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth. These include, but are not limited to, nonmodifiable factors (eg, fetal sex, weight, plurality), potentially modifiable antepartum and intrapartum factors (eg, location of delivery, intent to intervene by cesarean delivery or induction for delivery, administration of antenatal corticosteroids and magnesium sulfate), and postnatal management (eg, starting or withholding and continuing or withdrawing intensive care after birth). Antepartum and intrapartum management options vary depending upon the specific circumstances but may include short-term tocolytic therapy for preterm labor to allow time for administration of antenatal steroids, antibiotics to prolong latency after preterm premature rupture of membranes or for intrapartum group B streptococci prophylaxis, and delivery, including cesarean delivery, for concern regarding fetal well-being or fetal malpresentation. Whenever possible, periviable births for which maternal or neonatal intervention is planned should occur in centers that offer expertise in maternal and neonatal care and the needed infrastructure, including intensive care units, to support such services. This document describes newborn outcomes after periviable birth, provides current evidence and recommendations regarding interventions in this setting, and provides an outline for family counseling with the goal of

  15. Preterm birth: Transition to adulthood.

    Science.gov (United States)

    Allen, Marilee C; Cristofalo, Elizabeth; Kim, Christina

    2010-01-01

    Preterm birth is associated with greater difficulty with transitions from childhood to adolescence to adulthood. Adolescents and young adults born preterm have higher rates of cerebral palsy, intellectual disability, cognitive impairment, learning disability, executive dysfunction, attention deficit disorder, and social-emotional difficulties than their peers born fullterm. Compared to individuals born fullterm, more preterm survivors have major neurodevelopmental or psychiatric disability and need financial supports and societal resources. Neuroimaging studies of adolescents and adults born preterm report higher rates of brain injury, differences in regional brain structure, and different brain circuits than in those born fullterm. Making the transition to adulthood is more difficult for young adults who were born preterm than their peers born fullterm, in that fewer complete high school and higher education, find and keep meaningful employment, and live independently from their parents. As a group, they do not tend to be risk-takers, and they have lower rates of alcohol abuse, use of illicit drugs, and criminal offenses than do their peers. Despite their many challenges, the majority of adults born preterm function well, form personal relationships, integrate well into their community, and are as satisfied with their quality of life as are their peers. Concerns regarding current preterm infants, with more extremely preterm survivors, overwhelming our medical, educational, and societal resources should serve as an impetus for research on prevention of preterm births and brain injury, as well as how to support and promote their ongoing neuromaturation and recovery from injury.

    Kazemier, Brenda M.; Schuit, Ewoud; Mol, Ben Willem J.; Pajkrt, Eva; Ganzevoort, Wessel

    2014-01-01

    Objective. To compare birth weight ratio and birth weight percentile to express infant weight when assessing pregnancy outcome. Study Design. We performed a national cohort study. Birth weight ratio was calculated as the observed birth weight divided by the median birth weight for gestational age. The discriminative ability of birth weight ratio and birth weight percentile to identify infants at risk of perinatal death (fetal death and neonatal death) or adverse pregnancy outcome (perinatal death + severe neonatal morbidity) was compared using the area under the curve. Outcomes were expressed stratified by gestational age at delivery separate for birth weight ratio and birth weight percentile. Results. We studied 1,299,244 pregnant women, with an overall perinatal death rate of 0.62%. Birth weight ratio and birth weight percentile have equivalent overall discriminative performance for perinatal death and adverse perinatal outcome. In late preterm infants (33+0–36+6 weeks), birth weight ratio has better discriminative ability than birth weight percentile for perinatal death (0.68 versus 0.63, P  0.01) or adverse pregnancy outcome (0.67 versus 0.60, P < 0.001). Conclusion. Birth weight ratio is a potentially valuable instrument to identify infants at risk of perinatal death and adverse pregnancy outcome and provides several advantages for use in research and clinical practice. Moreover, it allows comparison of groups with different average birth weights. PMID:25197283

  17. Tritium releases, birth defects and infant deaths

    International Nuclear Information System (INIS)

    The AECB has published a report 'Tritium releases from the Pickering Nuclear Generating Station and Birth Defects and Infant Mortality in Nearby Communities 1971-1988' (report number INFO-0401). This presents the results of a detailed analysis of deaths and birth defects occurring in infants born to mothers living in the area (25 Km radius) of the Pickering nuclear power plant, over an 18-year period. The analysis looked at the frequency of these defects and deaths in comparison to the general rate for Ontario, and also in relation to airborne and waterborne releases of tritium from the power plant. The overall conclusion was that the rates of infant death and birth defects were generally not higher in the study population than in all of Ontario. There was no prevalent relationship between these deaths and defects and tritium releases measured either at the power plant or by ground monitoring stations t some distance from the facility

  18. Unsanctioned births in China.

    Science.gov (United States)

    Li, L; Ballweg, J A

    1995-05-01

    This study hypothesizes that "unsanctioned" births (beyond the limit authorized by the government) in China are more likely among couples who have strong traditional fertility norms and less likely among couples who adopt new family planning norms. The theoretical framework is based on cultural conflict theory as developed by Sellin. Data are obtained from 6654 ever married women aged under 49 years from the 1987 In-Depth Fertility Survey for Guangdong province. Over 30% of the sample were married before 20 years of age. 20% had 1 child, 26.7% had 2 children, about 23% had 3 children, 13.9% had 4 children, and under 10% had 5 or more children. The average number of living children was 2.5. Findings reveal that socioeconomic status was significantly related to unsanctioned births; they were more common in less developed areas and among women of lower socioeconomic status (SES). Persons living in areas with a high monetary contribution per person in family planning efforts at the county level were less likely to have unsanctioned births. Women who lived in urban areas, worked in state enterprises, and had parents with high educational status were less likely to have unsanctioned births. They were more likely among women who married at an early age, lived with parents after the marriage, had female living children, and had failed pregnancies. They were also more likely among women who had arranged marriages, a traditional desire for large family sizes, an early marriage ideal, and a preference for sons. Knowledge of family planning and greater use of abortion were related to a lower incidence of unsanctioned births. Women who talked with their husbands about their family size desires were less likely to have unsanctioned births. Parental educational attainment only had an influence among rural women. Variables impacted on fertility differently in urban and rural areas. PMID:12291551

    Introduction 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. Purpose 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. Materials and Methods 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. Results 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). Conclusions 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

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.

  14. Seasonality of births: stability and change in a developing country.

    1989-08-01

    A marked seasonality of births for the two main ethnic groups of peninsular Malaysia, far exceeding the cyclic fluctuations in births in the United States and Canada, was reported for the 1960s. A 36% excess of births over the average monthly number was observed among Malays each January. Among the ethnic Chinese in Malaysia a regular periodicity in the numbers of births was also found, but it was far less marked and the peak occurred in October or November. The peaks in both groups were due in large measure to conceptions that correlate with religious observances or holidays. Here I report on cyclic birth patterns in peninsular Malaysia for the period 1970-1985. Rapid economic development has occurred during this time and has brought with it demographic changes, such as a massive rise in contraceptive use and a decline in birth rates. These demographic changes have been accompanied by the loss of the pronounced seasonal pattern of births among the Malays. The seasonality of Malay births is now of roughly the same magnitude as the seasonality in the United States and Canada, whereas seasonality of births among the Chinese in Malaysia remains essentially unchanged.

    In the U.S. teen mothers are more likely to give birth to low birth weight babies than non-teen mothers. There is also substantial evidence that smoking is a risk factor correlated with low birth weight. Low birth weight is a costly outcome in both the short and long term for parents, children, and society at large. This paper examines the causal link between teen age smoking behavior and low birth weight. We use a variety of empirical techniques including fixed effects and a matching estimat...

MÉTODOS: Estudo prospectivo, observacional, de recém-nascidos com idade gestacional OBJECTIVE: To verify if respiratory rate (RR, tidal volume (TV and respiratory rate and tidal volume ratio (RR/TV could predict extubation failure in very low birth weight infants submitted to mechanical ventilation. METHODS: This prospective observational study enrolled newborn infants with gestational age <37 weeks and birth weight <1,500g, mechanically ventilated from birth during 48 hours to 30 days and thought to be ready for extubation. As soon as the physicians decided for extubation, the neonates received endotracheal continuous positive airway pressure (CPAP for 10 minutes while spontaneous RR, TV and RR/TV were measured using a fixed-orifice pneumotachograph positioned between the endotracheal tube and the ventilator circuit. Thereafter, the neonates were extubated to nasal CPAP. Extubation failure was defined as the need for reintubation within 48 hours. RESULTS: Of the 35 studied infants, 20 (57% were successfully extubated and 15 (43% required reintubation. RR and RR/TV before extubation had a trend to be higher in unsuccessfully extubated infants. TV was similar in both groups. Sensitivity and specificity of these parameters as predictors of extubation failure were 50 and 67% respectively for RR, 40 and 67% for TV and 40 and 73% for RR/TV. CONCLUSIONS: RR, TV and RR/TV showed low sensitivity and specificity to predict extubation failure in mechanically ventilated very low birth weight infants.

  2. Recent increase in sex ratio at birth in Viet Nam.

    Directory of Open Access Journals (Sweden)

    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.

  3. Aircraft noise and birth weight

    Knipschild, P.; Meijer, H.; Salle, H.

    1981-05-01

    Data from six infant welfare centres in the vicinity of Amsterdam airport were analysed. Birth weights of 902 infants were related to aircraft noise levels to which the mother was exposed in pregnancy. The analysis was restricted to deliveries in hospital, single births and mothers aged 20-34 years. In high noise areas the mean birth weight was 69 g lower than in low noise areas. Of the infants in high noise areas 24% had a birth weight less than 3000 g, compared with 18% in low noise areas. In the analysis the effect of sex of the infant, birth order and to some extent socio-economic status were taken into account. An effect of smoking seemed unlikely. The results, together with existing knowledge, give some suggestion that aircraft noise can decrease birth weight.

    Adolescent childbearing adversely affects both mothers and infants. The birth rate for US adolescent women of Hispanic origin is higher than that for US adolescents overall. Birth rates among US Hispanic adolescents in the border region are higher than rates among other US Hispanic adolescents, and rates among Mexican border adolescents are higher than rates among other Mexican adolescents. We used binational birth certificate data for US Hispanic and Mexican adolescent women living inside the border region, elsewhere within the border states, and in the US and Mexico overall to compare birth rates and other health indicators among these groups. From 2000 to 2009, birth rates for 15-19 year-olds declined 19-28 % among US Hispanic geographic subgroups and 8-13 % among Mexican geographic subgroups; rates in the border region in 2009 were 73.8/1,000 women ages 15-19 for US Hispanics and 87.2/1,000 for Mexicans and were higher than rates in other US and Mexican subgroups, respectively. Less than one in five US Hispanic and Mexican adolescent mothers in the border region was married. About one in three delivered by cesarean. Late or no prenatal care was more prevalent among US Hispanic (17.6 %) than Mexican (14.3 %) border adolescents. Birth weight and gestational age outcomes were generally poorest in Texas border counties compared with border counties in other US states and in municipios of Mexican states bordering Texas. High birth rates and low prenatal care utilization among adolescents are problems along the US-Mexico border. PMID:24820518

    2015-06-01

    What role does birth play in the debate about elective abortion? Does the wrongness of infanticide imply the wrongness of late-term abortion? In this paper, I argue that the same or similar factors that make birth morally significant with regard to abortion make meaningful viability morally significant due to the relatively arbitrary time of birth. I do this by considering the positions of Mary Anne Warren and José Luis Bermúdez who argue that birth is significant enough that the wrongness of infanticide does not imply the wrongness of late-term abortion. On the basis of the relatively arbitrary timing of birth, I argue that meaningful viability is the point at which elective abortion is prima facie morally wrong. PMID:25012846

    compared along with cost-effectiveness and acceptance of the model by patients. Data collection occurred primarily through medical record abstraction with the addition of two patient questionnaires. Comparability of the cohorts was established by using a validated methodology to determine medical/perinatal risk and birth center eligibility, which included assessment by two CNMs and an independent blind review by a perinatologist. The cost analysis uses a resource-utilization approach and new methodologies such as activity-based-costing to compare costs from both the perspective of the payor and the health care provider. Patient satisfaction was measured using a self-administered patient questionnaire.Results: Current preliminary results from approximately 38% of the final expected study sample are available. Crude and adjusted analysis have been conducted. Overall, the preliminary results suggest similar morbidity and mortality in the two groups. Fetal deaths are 0.75% in the index and 0.64% in the comparison group, with early neonatal deaths at 0.26% and 0.23%, respectively. The traditional care group showed adjusted rate differences of 5.83% more major maternal intrapartum complications and 9% more NICU admissions. While the birth center group showed adjusted rate differences of 5.5% more low birth weight and 0.95% more preterm birth. For other outcomes, the birth center group showed an adjusted rate difference of 22.34% more exclusive breastfeeding at discharge. Also, there was less utilization of cesarean section and assisted delivery in the birth center group as compared to the traditional care group. The adjusted rate difference for normal spontaneous vaginal deliveries in nulliparas was 10.23% more in the birth center group, with similar results in multiparas with and without history of cesarean (28.88% and 7.84%, respectively). Preliminary results also show that the average total cost for pregnancy-related services paid by California Medicaid was $4,550 for the

The material for such analysis was nomad women's fertility history that was in their reproductive period (15-44. The material itself was gathered through a health survey. The main sample was composed of 2,165 qualified women, of whom 49 due to previous or presently using contraceptive methods and 10 for the lack of enough data were excluded from 'this study. Purpose of analysis was to find a relation between No. of live births and pregnancies with total duration of married life (in other word, total months which the women were at risk of pregnancy. 2,106 women which their fertility history was analyzed had a totally of272, 502 months married life. During this time 8,520 live births did occurred which gave a birth interval of 32 months. As pregnancy termination could be through either live birth, still birth or abortion (induced or spontaneous, bringing all together will give No. of pregnancies which have occurred during this period (8,520 + 124 + 328 = 8,972 with an average of interpregnancy interval of 30.3 months. Considering the length of components of birth interval: Post partum amenorrhea which depends upon lactation. - Anovulatory cycles (2 month - Ooulatory exposure, in the absence of contraceptive methods (5 months - Pregnancy (9 months.Difference between the length, of birth interval from the sum of the mentioned period (except the first component, (2 + 5+ 9 = 16 will be duration of post partum amenorrhea (32 - 16 = 16, or in other word duration of breast feeding among nomad women.

    Background Institution-based childbirth, with the ultimate goal of universal access to skilled birth attendance (SBA), has been selected as a key strategy to reduce the maternal mortality rate in many developing countries. However, the question of how to engage traditional birth attendants (TBAs) in the advocacy campaign for SBA poses a number of challenges.

    2016-03-01

    Objective To investigate the association between prepregnancy obesity and birth outcomes using fixed effect models comparing siblings from the same mother. Methods A total of 7496 births to 3990 mothers from the National Longitudinal Survey of Youth 1979 survey are examined. Outcomes include macrosomia, gestational length, incidence of low birthweight, preterm birth, large and small for gestational age (LGA, SGA), c-section, infant doctor visits, mother's and infant's days in hospital post-partum, whether the mother breastfed, and duration of breastfeeding. Association of outcomes with maternal pre-pregnancy obesity was examined using Ordinary Least Squares (OLS) regression to compare across mothers and fixed effects to compare within families. Results In fixed effect models we find no statistically significant association between most outcomes and prepregnancy obesity with the exception of LGA, SGA, low birth weight, and preterm birth. We find that prepregnancy obesity is associated with a with lower risk of low birthweight, SGA, and preterm birth but controlling for prepregnancy obesity, increases in GWG lead to increased risk of LGA. Conclusions Contrary to previous studies, which have found that maternal obesity increases the risk of c-section, macrosomia, and LGA, while decreasing the probability of breastfeeding, our sibling comparison models reveal no such association. In fact, our results suggest a protective effect of obesity in that women who are obese prepregnancy have longer gestation lengths, and are less likely to give birth to a preterm or low birthweight infant.

    Birth defects (structural, functional and metabolic disorder present from birth, may be diagnosed later) rising up as an important cause of infant mortality even in developing countries where infant mortality has been reduced to much extent. Seventy percent of birth defects are preventable through the application of various cost effective community genetic services. Indian people are living in the midst of risk factors for birth defects, e.g., universality of marriage, high fertility, large number of unplanned pregnancies, poor coverage of antenatal care, poor maternal nutritional status, high consanguineous marriages rate, and high carrier rate for hemoglobinopathies. India being the second most populous country with a large number infant born annually with birth defects should focus its attention on strategies for control of birth defects. Many population based strategies such as iodization, double fortification of salt, flour fortification with multivitamins, folic acid supplementation, periconceptional care, carrier screening and prenatal screening are some of proven strategies for control of birth defects. Strategies such as iodization of salt in spite of being initiated for a long time in the past do have a very little impact on its consumption (only 50% were using iodized salt). Community genetic services for control of birth defects can be easily flourished and integrated with primary health care in India because of its well established infrastructure and personnel in the field of maternal and child health care. As there is wide variation for infant mortality rate (IMR) in different states in India, so there is a need of deferential approach to implement community genetic services in states those had already achieved national goal of IMR. On the other hand, states those have not achieved the national goal on IMR priority should be given to management of other causes of infant mortality. PMID:24019610

    A comparison of cohorts of ever-married Chanaian women suggests evidence of a fertility transition beginning among younger women and select subgroups. Ghana's crude birth rate declined from a high of 50/1000 population in 1970 to 38.8/1000 in 1985. To ascertain whether marital fertility is now being controlled through conscious attempts to lengthen birth intervals, World Fertility Survey data from 1979-80 on the timing of births among different birth cohorts were analyzed. It was hypothesized that, as a result of the influence of Western values that stress independence from parents and the introduction of compulsory education, cohorts of the mid-1950s and 1960s would be more likely to postpone childbearing, more active in the modern sector of the economy, and more accepting of modern contraceptive usage for birth spacing than women in the 1930-39, 1940-49, and 1950-59 cohorts. For the 1940-49 cohort, it took 10.8 months for 25% to have a birth following 1st marriage, 18.7 months for 50% to have a 1st birth, and 27.4 months for 75% to complete this step. By comparison, these figures for the 1955-64 birth cohort were 9.9, 16.7, and 20.5 months, respectively. The significantly shorter (p 0.01) interval between marriage and 1st birth found among younger women in part reflects rising age at marriage; mean age at 1st marriage was 17.9 years for the 1940 cohort and 21.6 years for the most recent cohort. After the birth of the 1st child, recent cohorts were more likely to wait longer for the 2nd birth. For women born in 1950-64, it took 21.8, 36.7, and 44.6 months for 25%, 50%, and 75%, respectively, to reach parity 2. This pattern of lengthened birth interval beyond the 1st birth was apparent at all parities in the youngest cohort and indicates increasing acceptance of contraception among those who have come of age during a period of rapid social change.

    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 risk of certain birth defects can be modified by maternal diet. A high-fat maternal mouse diet has recently been reported to substantially increase the penetrance of birth defects known to be associated with a deficiency of transcription factor Cited2 as well as induce cleft palate. These effects were associated with a more than twofold reduction in embryonic expression of Pitx2c. This investigation suggests the need to further explore this provocative gene-diet interaction in human studies.

    Our daily lives are a series of ordinary moments and unnoticed thresholds—times that define us in ways we often do not give much attention. While we consider childbirth to be one of life's extra-ordinary events, the hours of labor and birth need not be dramatic (or traumatic) ones. I describe a quiet, well-supported birth in the Netherlands that is cause for celebration of the beauty of an ordinary instant that can define and enrich the human experience.

    Full Text Available BACKGROUND: The extent to which baseline couple characteristics affect the probability of live birth and adverse perinatal outcomes after assisted conception is unknown. METHODS AND FINDINGS: We utilised the Human Fertilisation and Embryology Authority database to examine the predictors of live birth in all in vitro fertilisation (IVF cycles undertaken in the UK between 2003 and 2007 (n = 144,018. We examined the potential clinical utility of a validated model that pre-dated the introduction of intracytoplasmic sperm injection (ICSI as compared to a novel model. For those treatment cycles that resulted in a live singleton birth (n = 24,226, we determined the associates of potential risk factors with preterm birth, low birth weight, and macrosomia. The overall rate of at least one live birth was 23.4 per 100 cycles (95% confidence interval [CI] 23.2-23.7. In multivariable models the odds of at least one live birth decreased with increasing maternal age, increasing duration of infertility, a greater number of previously unsuccessful IVF treatments, use of own oocytes, necessity for a second or third treatment cycle, or if it was not unexplained infertility. The association of own versus donor oocyte with reduced odds of live birth strengthened with increasing age of the mother. A previous IVF live birth increased the odds of future success (OR 1.58, 95% CI 1.46-1.71 more than that of a previous spontaneous live birth (OR 1.19, 95% CI 0.99-1.24; p-value for difference in estimate <0.001. Use of ICSI increased the odds of live birth, and male causes of infertility were associated with reduced odds of live birth only in couples who had not received ICSI. Prediction of live birth was feasible with moderate discrimination and excellent calibration; calibration was markedly improved in the novel compared to the established model. Preterm birth and low birth weight were increased if oocyte donation was required and ICSI was not used. Risk of

    2014-12-01

    Childbearing is on the decline in the United States overall and among women under age 30 and women in each of the largest race and Hispanic origin groups. Childbearing continues to rise among older women, however, with rates for women aged 35 and over at the highest levels seen in approximately 50 years. After more than a decade of steady rises, cesarean delivery rates are trending slightly downward; a recent report revealed larger declines for 2009-2013 among women at low risk for cesarean delivery than for all women with cesareans. Following several years of relative stability, twinning rates were up for 2013; a recent report based on 2012 data revealed that triplet and higher-order multiple births have been trending sharply downward. Declines in the incidence of preterm deliveries, especially in conjunction with reductions in low birthweight (albeit modest) and in perinatal mortality, suggest some recent progress in improving pregnancy outcome in the United States. The forthcoming report "Births: Final Data for 2013" will present more information on the topics addressed in this report and selected others. PMID:25483923

    Bryant, Joanne; Porter, Maree; Tracy, Sally K; Sullivan, Elizabeth A

    2007-09-01

    This article draws on qualitative data to explore the beliefs through which decisions about caesarean birth are made and to consider how these might contribute to the increasing rate of caesarean birth. A total of 36 interviews were conducted in Australia, including 12 hospital-based midwives, 6 obstetricians, and 18 women who had experienced caesarean birth within the 2 years prior to the research interview. Data reveal a belief derived from the pervasive discourse of neo-liberalism that women are self-governing autonomous subjects in their birth experience, with entitlement to the consumption of birthing information and services, as guided by obstetricians. Feeding into this belief are coexisting discourses that serve to organise 'free choice' in terms of safe/unsafe, order/disorder, life/death; and with ontological meanings, by structuring women's mothering identities as good/bad. The neo-liberal obligation to manage risk and pursue success for both mothers and babies means that women (and others) are obliged to choose what is set up as the most obvious and sensible option: safe, ordered caesareans. The structuring of discourses in this way shows how caesareans can be positioned as a preferential means of birth. PMID:17590252

    Full Text Available Background: Congenital anomalies of urinary system are common and are found in 3-4% of population, and lethal urinary anomalies account for 10% of termination of pregnancy. Methods: A study was done to know the incidence of congenital anomalies at birth for the period of 4 months from May 99 - Sept 99 at Cheluvamba hospital attached to Mysore medical college. Congenital anomalies in the still births, live births and aborted fetuses >20 weeks were studied along with the case history and ultrasound reports. Aborted fetuses and still born babies were collected for autopsy after the consent of parents. These babies were fixed in 10% formalin and autopsy was done after fixing, and anomalies were noted. Results: Total births during study period were 3000. There were 61 babies with congenital anomalies and 6 babies had anomalies of urinary system. Among the urinary system anomalies 1 baby had bilateral renal agenesis, 1 baby had unilateral renal agenesis with anophthalmia (Fraser syndrome, 2 babies had Multicystic dysplastic kidney disease (MCDK and 1 live baby had hydronephrosis due to obstruction at pelvi ureteric junction, and 1 live female baby had polycystic kidneys. Conclusion: Incidence of urinary system anomalies in the present study was 2 per 1000 births. U/S detection of urinary anomalies varies with period of gestation, amniotic fluid volume and visualisation of urinary bladder. Autopsy helps to detect renal agenesis.

    Full Text Available BACKGROUND Dynamic population models, or models with changing vital rates, are only beginning to receive serious attention from mathematical demographers. Despite considerable progress, there is still no general analytical solution for the size or composition of a population generated by an arbitrary sequence of vital rates. OBJECTIVE The paper introduces a new approach, Intrinsic Linkage, that in many cases can analytically determine the birth trajectory of a dynamic birth-death population. METHODS Intrinsic Linkage assumes a weighted linear relationship between (i the time trajectory of proportional increases in births in a population and (ii the trajectory of the intrinsic rates of growth of the projection matrices that move the population forward in time. Flexibility is provided through choice of the weighting parameter, w, that links these two trajectories. RESULTS New relationships are found linking implied intrinsic and observed population patterns of growth. Past experience is "forgotten" through a process of simple exponential decay. When the intrinsic growth rate trajectory follows a polynomial, exponential, or cyclical pattern, the population birth trajectory can be expressed analytically in closed form. Numerical illustrations provide population values and relationships in metastable and cyclically stable models. Plausible projection matrices are typically found for a broad range of values of w, although w appears to vary greatly over time in actual populations. CONCLUSIONS The Intrinsic Linkage approach extends current techniques for dynamic modeling, revealing new relationships between population structures and the changing vital rates that generate them.

    Effective and coordinated teamworking is key to achieving safe birth for mothers and babies. Confidential enquiries have repeatedly identified deficiencies in teamwork as factors contributing to poor maternal and neonatal outcomes. The ingredients of a successful multi-professional team are varied, but research has identified some fundamental teamwork behaviours, with good communication, proficient leadership and situational awareness at the heart. Simple, evidence-based methods in teamwork training can be seamlessly integrated into a core, mandatory obstetric emergency training. Training should be an enjoyable, inclusive and beneficial experience for members of staff. Training in teamwork can lead to improved clinical outcomes and better birth experience for women.

    Full Text Available &lt;B&gt;Purpose:&lt;/B&gt; The authors analyzed the trend from the birth-related statistics of high birth weight infants (HBWIs over 50 years in Korea from 1960 to 2010. &lt;B&gt;Methods:&lt;/B&gt; We used 2 data sources, namely, the hospital units (1960’s to 1990’s and Statistics Korea (1993 to 2010. The analyses include the incidence of HBWIs, birth weight distribution, sex ratio, and the relationship of HBWI to maternal age. &lt;B&gt;Results:&lt;/B&gt; The hospital unit data indicated the incidence of HBWI as 3 to 7% in the 1960’s and 1970’s and 4 to 7% in the 1980’s and 1990’s. Data from Statistics Korea indicated the percentages of HBWIs among total live births decreased over the years: 6.7% (1993, 6.3% (1995, 5.1 % (2000, 4.5% (2000, and 3.5% (2010. In HBWIs, the birth weight rages and percentage of incidence in infants’ were 4.0 to 4.4 kg (90.3%, 4.5 to 4.9 kg (8.8%, 5.0 to 5.4 kg (0.8%, 5.5 to 5.9 kg (0.1%, and &gt;6.0 kg (0.0% in 2000 but were 92.2%, 7.2%, 0.6%, 0.0%, and 0.0% in 2009. The male to female ratio of HBWIs was 1.89 in 1993 and 1.84 in 2010. In 2010, the mother's age distribution correlated with low (4.9%, normal (91.0%, and high birth weights (3.6%: an increase in mother's age resulted in an increase in the frequency of low birth weight infants (LBWIs and HBWIs. &lt;B&gt;Conclusion:&lt;/B&gt; The incidence of HBWIs for the past 50 years has been dropping in Korea. The older the mother, the higher was the risk of a HBWI and LBWI. We hope that these findings would be utilized as basic data that will aid those managing HBWIs.

    2004-01-01

    We have built a model to predict optimal age at first birth for women in a natural fertility population. The only existing fully evolutionary model, based on Ache hunter-gatherers, argues that as women gain weight, their fertility (rate of giving birth) increases-thus age at first birth represents a trade-off between time allocated to weight gain and greater fertility when mature. We identify the life-history implications of female age at first birth in a Gambian population, using uniquely de...

  16. A spatial bivariate probit model for correlated binary data with application to adverse birth outcomes.

    Neelon, Brian; Anthopolos, Rebecca; Miranda, Marie Lynn

    2014-04-01

    Motivated by a study examining geographic variation in birth outcomes, we develop a spatial bivariate probit model for the joint analysis of preterm birth and low birth weight. The model uses a hierarchical structure to incorporate individual and areal-level information, as well as spatially dependent random effects for each spatial unit. Because rates of preterm birth and low birth weight are likely to be correlated within geographic regions, we model the spatial random effects via a bivariate conditionally autoregressive prior, which induces regional dependence between the outcomes and provides spatial smoothing and sharing of information across neighboring areas. Under this general framework, one can obtain region-specific joint, conditional, and marginal inferences of interest. We adopt a Bayesian modeling approach and develop a practical Markov chain Monte Carlo computational algorithm that relies primarily on easily sampled Gibbs steps. We illustrate the model using data from the 2007-2008 North Carolina Detailed Birth Record. PMID:22599322

    Alterations of pulmonary microbiome have been recognized in multiple respiratory disorders. It is critically important to ascertain if an airway microbiome exists at birth and if so, whether it is associated with subsequent lung disease. We found an established diverse and similar airway microbiome at birth in both preterm and term infants, which was more diverse and different from that of older preterm infants with established chronic lung disease (bronchopulmonary dysplasia). Consistent temporal dysbiotic changes in the airway microbiome were seen from birth to the development of bronchopulmonary dysplasia in extremely preterm infants. Genus Lactobacillus was decreased at birth in infants with chorioamnionitis and in preterm infants who subsequently went on to develop lung disease. Our results, taken together with previous literature indicating a placental and amniotic fluid microbiome, suggest fetal acquisition of an airway microbiome. We speculate that the early airway microbiome may prime the developing pulmonary immune system, and dysbiosis in its development may set the stage for subsequent lung disease. PMID:27488092

    As of April 2010, all maternity care at government healthcare facilities in Sierra Leone is provided at no cost to patients. In late 2010, we conducted a community health census of 18 sections of the city of Bo (selected via randomized cluster sampling from 68 total sections). Among the 3421 women with a history of pregnancy who participated in the study, older women most often reported having a history of both home and hospital deliveries, while younger women showed a preference for hospital births. The proportion of lastborn children delivered at a healthcare facility increased from 71.8% of offspring 10-14 years old to 81.1% of those one to nine years old and 87.3% of infants born after April 2010. These findings suggest that the new maternal healthcare initiative has accelerated an existing trend toward a preference for healthcare facility births, at least in some urban parts of Sierra Leone.

  17. Prevalence at birth of congenital malformations in communities near the Hanford site

    International Nuclear Information System (INIS)

    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

  18. The Australian baby bonus maternity payment and birth characteristics in Western Australia.

    Directory of Open Access Journals (Sweden)

    Kristjana Einarsdóttir

    Full Text Available BACKGROUND: The Australian baby bonus maternity payment introduced in 2004 has been reported to have successfully increased fertility rates in Australia. We aimed to investigate the influence of the baby bonus on maternal demographics and birth characteristics in Western Australia (WA. METHODS AND FINDINGS: This study included 200,659 birth admissions from WA during 2001-2008, identified from administrative birth and hospital data-systems held by the WA Department of Health. We estimated average quarterly birth rates after the baby bonus introduction and compared them with expected rates had the policy not occurred. Rate and percentage differences (including 95% confidence intervals were estimated separately by maternal demographics and birth characteristics. WA birth rates increased by 12.8% following the baby bonus implementation with the greatest increase being in mothers aged 20-24 years (26.3%, 95%CI = 22.0,30.6, mothers having their third (1.6%, 95%CI = 0.9,2.4 or fourth child (2.2%, 95%CI = 2.1,2.4, mothers living in outer regional and remote areas (32.4%, 95%CI = 30.2,34.6, mothers giving birth as public patients (1.5%, 95%CI = 1.3,1.8, and mothers giving birth in public hospitals (3.5%, 95%CI = 2.6,4.5. Interestingly, births to private patients (-4.3%, 95%CI = -4.8,-3.7 and births in private hospitals (-6.3%, 95%CI = -6.8,-5.8 decreased following the policy implementation. CONCLUSIONS: The introduction of the baby bonus maternity payment may have served as an incentive for women in their early twenties and mothers having their third or fourth child and may have contributed to the ongoing pressure and staff shortages in Australian public hospitals, particularly those in outer regional and remote areas.

  19. First birth trends in developed countries: Persisting parenthood postponement

    Directory of Open Access Journals (Sweden)

    2006-09-01

    Full Text Available Levels and trends of various facets concerning first births are continuously changing. The evidence confirms that the postponement of first births is an ongoing and persisting process which started in western countries among cohorts of the 1940s, but only in the 1960s cohorts in Central and Eastern Europe. The mean age of women having first births is universally rising. Fertility of older women was increasing. The decline in childbearing of young women is robust among the cohorts of the late 1960s and the 1970s; in Southern Europe as well as in central and Eastern Europe the rates of decline have accelerated. Childbearing behavior in the formerly socialist countries is in transition to a different regime.

    The problems of maternal malnutrition, low birthweight, and infant mortality and morbidity were investigated in a prospective study (1981-85) involving 7586 pregnant women (3197 from urban areas and 4389 from rural areas) in India. The mothers were followed until their infants were 1 year of age. There were 6879 live births among these women and 208 still births (a rate of 29.3/1000 deliveries). The perinatal, neonatal, and infant mortality rates were 65.3/1000, 57.7/1000, and 94.5/1000, respectively. 90% of these deaths involved infants with a birthweight below 2000 grams. Overall, 39% of infants studied were classified as low birthweight (under 2500 grams). Factors associated with low birthweight included maternal age below 19 years or over 35 years, maternal weight below 40 kg, maternal height below 145 cm, weight gain during pregnancy of under 5 kg, an interpregnancy interval less than 24 months, hemoglobin less than 8 grams%, and maternal illiteracy. Moderate to severe morbidity (neonatalas phyxia) was found in 10% of the births in this series. Breastfeeding was delayed beyond 24 hours in 77% of rural births and 13% of urban births; 30% of infants in both settings were given a bottle within the 1st week of life. 98% of rural mothers and 85% of urban mothers did not utilize available maternal-child health services in the postpartum period. Reducing the incidence of low birthweight births through primary health care interventions such as screening, food supplementation, adequate prenatal care, and correction of maternal nutritional deficiencies is the best strategy for improving infant survival in India. In the interim period, adequate health care must be made available to low birthweight infants and proper feeding practices should be promoted. PMID:3440594

  5. The partial-birth stratagem.

    Science.gov (United States)

    1998-06-01

    In Wisconsin, physicians stopped performing abortions when a Federal District Court Judge refused to issue a temporary restraining order against the state's newly enacted "partial birth" abortion ban that was couched in such vague language it actually covered all abortions. While ostensibly attempting to ban late-term "intact dilation and extraction," the language of the law did not refer to that procedure or to late terms. Instead, it prohibited all abortions in which a physician "partially vaginally delivers a living child, causes the death of the partially delivered child with the intent to kill the child and then completes the delivery of the child." The law also defined "child" as "a human being from the time of fertilization" until birth. It is clear that this abortion ban is unconstitutional under Row v. Wade, and this unconstitutionality is compounded by the fact that the law allowed no exception to protect a woman's health, which is required by Roe for abortion bans after fetal viability. Wisconsin is only one of about 28 states that have enacted similar laws, and only two have restricted the ban to postviability abortions. Many of these laws have been struck down in court, and President Clinton has continued to veto the Federal partial-birth bill. The Wisconsin Judge acknowledged that opponents of the ban will likely prevail when the case is heard, but his action in denying the temporary injunction means that many women in Wisconsin will not receive timely medical care. The partial birth strategy is really only another anti-abortion strategy. PMID:12348556

  9. Allostatic Load and Preterm Birth

    Directory of Open Access Journals (Sweden)

    David M. Olson

    2015-12-01

    Full Text Available Preterm birth is a universal health problem that is one of the largest unmet medical needs contributing to the global burden of disease. Adding to its complexity is that there are no means to predict who is at risk when pregnancy begins or when women will actually deliver. Until these problems are addressed, there will be no interventions to reduce the risk because those who should be treated will not be known. Considerable evidence now exists that chronic life, generational or accumulated stress is a risk factor for preterm delivery in animal models and in women. This wear and tear on the body and mind is called allostatic load. This review explores the evidence that chronic stress contributes to preterm birth and other adverse pregnancy outcomes in animal and human studies. It explores how allostatic load can be used to, firstly, model stress and preterm birth in animal models and, secondly, how it can be used to develop a predictive model to assess relative risk among women in early pregnancy. Once care providers know who is in the highest risk group, interventions can be developed and applied to mitigate their risk.

This article discusses the birth environment from the perspective of understanding the aromas and aromatherapy for the benefit of women and midwives The dynamic between the olfactory system and stimulation of normal birth processes proves to be fascinating. By examining other health models of care we can incorporate simple but powerful methods that can shape clinical outcomes. There is still more that midwives can do by using aromatherapy in the context of a multisensory approach to make birth environments synchronise with women's potential to birth in a positive way.

    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 ...

    Full Text Available Abstract Background Birth Defects are a series of diseases that seriously affect children's health. Birth defects are generally caused by several interrelated factors. The aims of the article is to estimate the prevalence rate and types of birth defects in Inner Mongolia, China, to compare socio-demographic characteristics among the children with birth defects and to analyze the association between risk factors and birth defects. Methods Data used in this study were obtained through baseline survey of Inner Mongolia Birth Defects Program, a population-based survey conducted from 2005 to 2008. The survey used cluster sampling method in all 12 administrative districts of Inner Mongolia. Sampling size is calculated according to local population size at a certain percentage. All live births, stillbirths and abortions born from October 2005 to September 2008, whose families lived in Inner Mongolia at least one year, were included. The cases of birth defects were diagnosed by the clinical doctors according to their experiences with further laboratory tests if needed. The inclusion criteria of the cases that had already dead were decided according to death records available at local cites. We calculated prevalence rate and 95% confidence intervals of different groups. Outcome variable was the occurrence of birth defects and associations between risk factors and birth defects were analyzed by using Poisson regression analysis. Results 976 children with birth defects were diagnosed. The prevalence rate of birth defects was 156.1 per 10000 births (95%CI: 146.3-165.8. The prevalence rate of neural tube defect (20.1 per 10000 births including anencephaly(6.9 per 10000, spina bifida (10.6 per 10000, and encephalocele (2.7 per 10000 was the highest, followed by congenital heart disease (17.1 per 10000. The relative risk (RR for maternal age less than 25 was 2.22 (95%CI: 2.05, 2.41. The RR of the ethnic Mongols was lower than Han Chinese (RR: 0.84; 95%CI: 0

    Full Text Available The objective of this study was to evaluate the effect of the size class of the litter at birth on the variation in birth and weaning weights and on the survival rate of piglets from birth to weaning. For this purpose, records of individual weight at birth and weaning of piglets obtained from a database of 295 Landrace litters born between 2000 and 2010 on a pig farm in the western region of the State of Paraná were used. The litters were classified as small (up to 7 piglets, medium (8 to 13 piglets, and large (> 14 piglets according to the total number of piglets born. The data were analyzed considering the effects of the year of sow mating and size class of the litter at birth. The correlations between mean weight and variance in litter weight and size were higher for medium and large litters. The size class of the litter significantly influenced the mean weight of piglets at birth and weaning and the variance in birth weight. Piglets born in medium and large litters weighed less and exhibited greater birth weight variation and a lower survival rate until weaning than piglets born in small litters.

    Full Text Available Objective: Cardiotocography is a tool for assessing the fetus during labor and identification the risk of asphyxia. Abnormal cardiotocography can induce stress on the physician and mother and can result in their deciding to terminate the pregnancy and the complications of an emergency cesarean section. The purpose of this study was the evaluation of the correlation between non-reassuring patterns in fetal cardiotocography and birth asphyxia. Materials and methods: In a cross-sectional analytic study, 324 term pregnant women were included, and the association between non-reassuring patterns in cardiotocography (fetal tachycardia, fetal bradycardia, absent or minimal baseline variability, and absence of acceleration and periodic or episodic deceleration and birth asphyxia were assessed. Results: Birth asphyxia existed in 10 newborns; in all cases mild hypoxic ischemic encephalopathy was observed. Within the non-reassuring cardiotocography patterns, baseline fetal heart variability and periodic or episodic deceleration had a significant relationship with birth asphyxia. Most asphyxia cases had occurred in absent and minimal baseline fetal heart rate (FHR variability (R = 0.49, P < 0.001. In periodic or episodic decelerations, most asphyxia cases occurred in recurrent late decelerations with normal baseline variability and variable decelerations with shoulders or overshoots (R = 0.42, P = 0.014. Conclusion: With regard to the findings of the present study, we can use non-reassuring cardiotocographic patterns, especially absent and minimal baseline FHR variability and periodic or episodic decelerations, in prediction of birth asphyxia. But it seems that most birth asphyxias occur in normal cardiotocographs.

    Scientists using the Hubble telescope have been amazed by the number of stars being created in galaxy NGC 3310. But while some scientists are observing the birth of new stars, others are predicting the end of the universe. According to supersymmetry it is possible that the universe could spontaneously change to a state where the electric force is switched off, resulting in the disintegration of all matter. Called 'vacuum fluctuation', this event is even less likely than winning the lottery jackpot twice in the same day however (1/2 page).

    2016-02-01

    While the preterm neonate continues to benefit from improved perinatal care, the rate of preterm birth in the United States remains significant. An increasing body of scientific literature has demonstrated the benefits of maternal progesterone administration in reducing primary and recurrent preterm birth. Intramuscular hydroxyprogesterone caproate is indicated in singleton pregnancies in women with a prior spontaneous preterm birth, while vaginal progesterone demonstrates similar efficacy in prolonging pregnancy in women with asymptomatic cervical shortening in the midtrimester. Given these favorable benefits, the use of progesterone has been expanded to other clinical situations at risk for preterm birth with less rigorous scientific evidence. This review highlights the current evidence-based clinical applications of progesterone for prevention of preterm birth. PMID:26788788

    2011-01-01

    Full Text Available For ten years, the incidence of preterm birth does not decrease in developed countries despite the promotion of public health programs. Many risk factors have been identified including ethnicity, age, tobacco, and infection. However, almost 50% of preterm birth causes remain unknown. The periodontal diseases are highly prevalent inflammatory and infectious diseases of tooth supporting tissues leading to an oral disability. They influence negatively general health worsening cardiovascular diseases and diabetes. Periodontal diseases have been also suspected to increase the rate of preterm birth, but data remain contradictory. The objective of this review is to present the principal results of epidemiological, biological, and interventional studies on the link between periodontal diseases and preterm birth. The conclusions of this work underline the importance for the physician/obstetrician to identify women at risk for preterm birth and to address these patients to dentist for periodontal examination and treatment in order to limit adverse pregnancy outcomes.

    Full Text Available Abstract Background Publicly insured women usually have a different demographic background to privately insured women, which is related to poor neonatal outcomes after birth. Given the difference in nature and risk of preterm versus term births, it would be important to compare adverse neonatal outcomes after preterm birth between these groups of women after eliminating the demographic differences between the groups. Methods The study population included 3085 publicly insured and 3380 privately insured, singleton, preterm deliveries (32–36 weeks gestation from Western Australia during 1998–2008. From the study population, 1016 publicly insured women were matched with 1016 privately insured women according to the propensity score of maternal demographic characteristics and pre-existing medical conditions. Neonatal outcomes were compared in the propensity score matched cohorts using conditional log-binomial regression, adjusted for antenatal risk factors. Outcomes included Apgar scores less than 7 at five minutes after birth, time until establishment of unassisted breathing (>1 minute, neonatal resuscitation (endotracheal intubation or external cardiac massage and admission to a neonatal special care unit. Results Compared with infants of privately insured women, infants of publicly insured women were more likely to receive a low Apgar score (ARR = 2.63, 95% CI = 1.06-6.52 and take longer to establish unassisted breathing (ARR = 1.61, 95% CI = 1.25-2.07, yet, they were less likely to be admitted to a special care unit (ARR = 0.84, 95% CI = 0.80-0.87. No significant differences were evident in neonatal resuscitation between the groups (ARR = 1.20, 95% CI = 0.54-2.67. Conclusions The underlying reasons for the lower rate of special care admissions in infants of publicly insured women compared with privately insured women despite the higher rate of low Apgar scores is yet to be determined.

    Full Text Available Background Low birth weight (LBW has long been used as an indicator of public health. Low birth weight is not a proxy for any dimension of other maternal or perinatal health outcomes. Low birth weight infants require special care, and have more chronic conditions, learning delays, and attention deficit hyperactivity disorders compared to infants of normal birth weight (NBW. Social competence is viewed as a primary component of healthy function and development and is an important predictor of academic and financial success. Objective To examine social competence of children aged 3-5 years born with low birth weight. Methods This cross-sectional study was undertaken in Palembang in 2012. Subjects consisted of children aged 3-5 years attended a preschool in the Seberang Ulu I District, Palembang, and were divided into two groups: low birth weight (LBW and normal birth weight (NBW. Social competence was assessed by observation and Interaction Rating Scale (IRS and Parenting Style questionnaire (PSQ. Chi-square analysis was used to compare social competence between the two groups. Multivariate regression logistic analysis was used to assess for the dominant factors that may affect a child’s social competence. Results Low birth weight children aged 3 to 5 years had a 1.435 times higher risk of low social competence compared to normal birth weight children of similar age. (RP 1.435; 95%CI 1.372 to 13.507; P=0.019. Multivariate regression logistic analysis revealed that parenting style was a dominant factor affecting social competence. Conclusion Social competence in 3 to 5-year-old children born with low birth weight is lower compared to those with normal birth weight. [Paediatr Indones. 2015;55:158-63.].

    The study determined the incidence of low birth weight (LBW), small for gestational age (SGA), preterm birth, and perinatal morbidity among Asian Indians (AI) in New Jersey (NJ), as well as identified predictors of SGA. We analyzed birth records for singletons born to mothers identified as AI and non-Hispanic white from 2008 to 2011, obtained from the NJ Department of Health. For AI, rates of LBW and SGA were elevated, rates of preterm birth were similar, and neonatal intensive care unit admission was lower, compared to whites. Factors associated with SGA in AI included nulliparity, anemia, hypertension, placental abruption, and lack of prenatal care. Maternal education, marital status, substance abuse, and timing of prenatal care were associated with SGA in whites, but not in AI. SGA incidence was higher among AI despite preterm rates similar to whites. Anemia was associated with SGA uniquely among AI. PMID:25047404

    The subject of this thesis is the non-homogeneous birth-death process with some of its special cases and its use in modeling epidemic data. This model describes changes in the size of a population. New population members can appear with a rate, called the birth rate or the reproductive power, and members can leave the population with a rate called the death rate. These rates are taken to be non-homogeneous in time. The Lagrange transform is used to derive the probability distribution function...

    Birth defects are an urgent global health priority. They affect millions of births worldwide. But their prevalence and impact are largely under-ascertained, particularly in middle- and low-income countries. Fortunately, a large proportion of birth defects can be prevented. This review examines the global prevalence and primary prevention methods for major preventable birth defects: congenital rubella syndrome, folic acid-preventable spina bifida and anencephaly, fetal alcohol syndrome, Down syndrome, rhesus hemolytic disease of the fetus and the newborn; and those associated with maternal diabetes, and maternal exposure to valproic acid or iodine deficiency during pregnancy. Challenges to prevention efforts are reviewed. The aim of this review is to bring to the forefront the urgency of birth defects prevention, surveillance, and prenatal screening and counseling; and to help public health practitioners develop population-based birth defects surveillance and prevention programs, and policy-makers to develop and implement science-based public health policies.

    Background: A previous randomized trial demonstrated an association between coffee intake and birth weight in smokers only. This could be a chance finding or because smoking interferes with caffeine metabolism. This study assessed the association between coffee intake during pregnancy and birth...... weight and whether it was modified by the mothers' smoking habits. Methods: In the Danish National Birth Cohort, coffee intake and smoking during pregnancy were recorded prospectively in 89,539 pregnancies that ended with live born singletons. Information on birth weight was obtained from the Danish...... Medical Birth Register. For a total of 71,000 pregnancies, complete information was available on coffee intake and all covariates for the second trimester. Results: Second-trimester coffee intake was associated with reduced birth weight in a dose–response pattern for non-smokers and smokers (9 g...

  13. Secondary recurrent miscarriage is associated with previous male birth.

    Ooi, Poh Veh

    2011-01-01

    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.

    Full Text Available To find any favored zodiac sign for celebrity births, a sample of 100 celebrities were randomly selected from people of different walks of life. The sample contained politicians, natural scientists, social scientists, Authors of literary works, social workers, humanitarian workers, business personnel, sports icons, singers, actors, actresses, etc. etc. from history and from the current time. The zodiac signs for the celebrities were found from their known dates of births. In the analysis of data, zodiac signs and the number of celebrities were represented as the independent x and the dependent y variables, respectively. For academic interests for the 9th grade high school juniors (at the time of the project performance, the co-authors of this article, as well as for the potentially illustrative uses in high school mathematics textbooks, bar and scatter plots were made, the line of best-fit and the equation of the line were found, probabilities of occurrences of celebrities for each of the zodiac signs were calculated and the correlation coefficients between the variables were determined for the sample. It was found that the zodiac Aquarius has the largest number of celebrities in the sample and that the two variables are moderately correlated. The sample sizes which were increased to 200 and then 300. By including another 100 more celebrities to find if the trend remains unchanged. In all the three cases, Aquarius turned out to be the zodiac when most of the celebrities are born.

    Full Text Available People born preterm at very low birth weight (VLBW, ≤1500g have higher rates of risk factors for adult-onset diseases, including cardiovascular diseases and type 2 diabetes. These risks may be mediated through epigenetic modification of genes that are critical to normal growth and development.We measured the methylation level of an imprinted insulin-like-growth-factor 2 (IGF2 locus (IGF2/H19 in young adults born preterm at VLBW and in their peers born at term. We studied 158 VLBW and 161 control subjects aged 18 to 27 years from the Helsinki Study of Very Low Birth Weight Adults. Methylation fraction at two IGF2 differentially methylated regions (DMRs - IGF2 antisense transcript (IGF2AS, also known as IGF2 DMR0 and last exon of IGF2 (IGF2_05, also known as IGF2 DMR2 - were measured with Sequenom Epityper. We used linear regression and adjustment for covariates to compare methylation fractions at these DMRs between VLBW and control subjects.At one IGF2AS CpG site, methylation was significantly lower in VLBW than in control subjects, mean difference -0.017 (95% CI; -0.028, -0.005, P = 0.004. Methylation at IGF2_05 was not different between the groups.Methylation of IGF2AS is altered 20 years after preterm birth at VLBW. Altered methylation may be a mechanism of later increased disease risk but more data are needed to indicate causality.

    Full Text Available Low birth weight and preterm babies have been increasing in Spain since 1980, coinciding with important changes in the social and demographic structure of childbearing populations—including the contribution of a 25% of foreign mothers—and with increasing medical intervention in births. This study, based on 5,990,613 births, compares the temporary trends in reproductive patterns and birth outcomes in Spanish and foreign mothers during the period 1996–2009 and evaluates for the years 2007 to 2009 the relative contribution of mother's origin and Caesarean section to birth weight variability. Foreign mothers maintain their own reproductive pattern, whereas negative birth outcomes increase in all groups. Results from logistic regression analysis show that besides late maternity and primiparity also Caesarean section increases the risk for low birth weight. The reduction in Caesarean section rates between 2007 and 2009 might explain the reduction of low birth weight detected. A change of tendency simultaneously appears in most maternal and newborn characteristics, and in the mode of delivery in all ethnic groups since 2008. Coincidence in the timing of the change of trends points to a common factor. We suggest that the current world financial crisis could be this common cause, a hypothesis to be contrasted in future research.

    In comparison to other European countries, West Germany displays relatively low rates of non-marital childbearing. Since the 1960, there has been a postponement of first birth, an increase in the age at first marriage and an increase in childlessness. Nevertheless, childbearing and marriage remained strongly coupled. In the former East Germany, on the other hand, non-marital childbearing was relatively high compared to other European countries and particularly compared to West Germany. In 198...

    The training of traditional birth attendants (TBAs) as a national public health strategy was implemented in the late 1970's in Zimbabwe. Since 1982, the Manicaland rural health programs have trained 6000 women in 12-week courses to change their practices of using unsterilized razor blades, shards of glass, or knives to sever the umbilical cord. These practices and others had led to high rates of neonatal tetanus mortality and maternal mortality. TBAs learned from state certified nurses the basics of personal and domestic hygiene, identification of pregnancy and associated risk factors, the importance of good nutrition, rest, and immunization for pregnant women, and safe practices in labor and delivery. Refresher courses and additional training in prenatal care and family planning have been added recently to the program. Completion of the program leads to a public recognition of their graduation in the base village. Maternity care services are provided as back up. This includes village based maternity waiting homes for women in labor, community health workers, and auxiliary midwives with higher level training. A district health center has been set up for more complicated cases. This access to better health care has led to a 50 and 66% reduction in maternal and infant mortality rates, respectively. A 1988 government survey shows increases in the use of contraceptives and the number of women receiving prenatal care. The components of the program which have contributed to program success and provided similarities to other country's TBA programs are as follows: developing a sense of self esteem and pride among TBAs for their work, utilizing creative ways to teach the largely illiterate TBA population through role plays and songs, and providing involvement in the health care system which reaffirms the TBA's importance. In spite of the advancements made however, there are still problems to solve. Unsafe practices are resorted to when TBAs forget their training

    The generation of cells in the human body has been difficult to study and our understanding of cell turnover is limited. Extensive testing of nuclear weapons resulted in a dramatic global increase in the levels of the isotope {sup 14}C in the atmosphere, followed by an exponential decrease after the test ban treaty in 1963. We show that the level of {sup 14}C in genomic DNA closely parallels atmospheric levels, and can be used to establish the time point when the DNA was synthesized and cells were born. We use this strategy to determine the age of cells in the cortex of the adult human brain, and show that whereas non-neuronal cells are exchanged, occipital neurons are as old as the individual, supporting the view that postnatal neurogenesis does not take place in this region. Retrospective birth dating is a generally applicable strategy that can be used to measure cell turnover in man under physiological and pathological conditions.

  11. Alcohol Taxes and Birth Outcomes

    Full Text Available This study examines the relationships between alcohol taxation, drinking during pregnancy, and infant health. Merged data from the US Natality Detailed Files, as well as the Behavioral Risk Factor Surveillance System (1985–2002, data regarding state taxes on beer, wine, and liquor, a state- and year-fixed-effect reduced-form regression were used. Results indicate that a one-cent ($0.01 increase in beer taxes decreased the incidence of low-birth-weight by about 1–2 percentage points. The binge drinking participation tax elasticity is −2.5 for beer and wine taxes and −9 for liquor taxes. These results demonstrate the potential intergenerational impact of increasing alcohol taxes.

  12. Association between order of birth and chronic malnutrition of children: a study of nationally representative Bangladeshi sample.

    2016-02-01

    This paper examines the net effect of birth order on child nutritional status in Bangladesh using data from the Bangladesh Demographic Health Survey, 2011 (BDHS). Analyses were restricted to 4,120 surviving, lastborn singleton children who were younger than 36 months at the time of the survey. Logistic regression was used to assess the association between birth order and child nutritional status. Results indicate 38.1% children are stunted and 8.2% children are fifth or higher order birth. Order of birth is one of the significant predictors of child being stunted. Third order, fourth order, and fifth or higher order children are 24%, 30%, and 72%, respectively, more likely to be stunted after adjusting for all other variables. Besides birth order, results also indicate that child age, size at birth, birth intention, maternal education, maternal body mass index, wealth index, place of residence and mass media access exert strong influences over child malnutrition. Reducing birth rates which limit number of births and birth order as well may reduce child malnutrition in Bangladesh. PMID:26958818

  13. Frequency of marriage and live birth among survivors prenatally exposed to the atomic bomb

    International Nuclear Information System (INIS)

    Frequency of marriage and birth as of January 1973 was determined for persons exposed in utero to the atomic bombs in 1945 and for controls. The marriage rate was lower in persons heavily exposed in utero than in the non-exposed or lightly exposed. This difference is attributed partly to the lesser marriageability of persons with mental retardation who are significantly more numerous among the heavily exposed, and partly to unmeasured variables, possibly including social discrimination against survivors of the atomic bomb. No consistent relation was observed between radiation exposure and three reproductive indices: childless marriages, number of births, and interval between marriage and first birth

    At birth, the transition to newborn life is triggered by lung aeration, which stimulates a large increase in pulmonary blood flow (PBF). Current theories predict that the increase in PBF is spatially related to ventilated lung regions as they aerate after birth. Using simultaneous phase-contrast X-ray imaging and angiography we investigated the spatial relationships between lung aeration and the increase in PBF after birth. Six near-term (30-day gestation) rabbits were delivered by caesarean section, intubated and an intravenous catheter inserted, before they were positioned for X-ray imaging. During imaging, iodine was injected before ventilation onset, after ventilation of the right lung only, and after ventilation of both lungs. Unilateral ventilation increased iodine levels entering both left and right pulmonary arteries (PAs) and significantly increased heart rate, iodine ejection per beat, diameters of both left and right PAs, and number of visible vessels in both lungs. Within the 6th intercostal space, the mean gray level (relative measure of iodine level) increased from 68.3 ± 11.6 and 70.3 ± 7.5%·s to 136.3 ± 22.6 and 136.3 ± 23.7%·s in the left and right PAs, respectively. No differences were observed between vessels in the left and right lungs, despite the left lung not initially being ventilated. The increase in PBF at birth is not spatially related to lung aeration allowing a large ventilation/perfusion mismatch, or pulmonary shunting, to occur in the partially aerated lung at birth.

  2. Birth defects in perinatal infants in areas contiguous to Hongyanhe Nuclear Power Plant before its normal operation

    International Nuclear Information System (INIS)

    Objective: To understand the status of birth defects among the perinatal infants in the areas contiguous to Hongyanhe nuclear power plant before its normal operation, so as to provide background information for the evaluation of the impact of nuclear power plant on birth defects. Methods: From 1 October 1995 to 30 September 2009 the midwifery units at second class and above of Wafangdian City were asked to be in charge of recording the birth defects among the perinatal infants born during this period within the range of 50 km around the Hongyanhe nuclear power plant. Results: The total number of birth defects was 697, and the maternal number Was 83779. The average defect rate Was 83.20/104. There were significant differences in the birth defect rate among different years (χ2=39.54, P<0.05), however, without linear trend therein,and among the survey areas (χ2=15.36, P<0.05) as well. The top five birth defects were congenital heart disease (148 cases), cleft lip with cleft palate (67 cases), congenital hydrocephalus (63 cases), and spina bifida (37 cases) and cleft lip (36 cases). Conclusions: The birth defect rate within the range of 50 km around the Hongyanhe nuclear power plant is lower than that of the region of Liaoning Province and the national rate of birth defects.

    Full Text Available Abstract Background Use of highly active antiretroviral therapy (HAART, a triple-drug combination, in HIV-infected pregnant women markedly reduces mother to child transmission of HIV and decreases maternal morbidity. However, there remains uncertainty about the effects of in utero exposure to HAART on foetal development. Methods Our objectives were to investigate whether in utero exposure to HAART is associated with low birth weight and/or preterm birth in a population of South African women with advanced HIV disease. A retrospective observational study was performed on women with CD4 counts ≤250 cells/mm3 attending antenatal antiretroviral clinics in Johannesburg between October 2004 and March 2007. Low birth weight ( Results Among HAART-unexposed infants, 27% (60/224 were low birth weight compared with 23% (90/388 of early HAART-exposed (exposed 3 increase, 95% CI 0.45-0.71, p 3 increase, 95% CI 0.55-0.85, p = 0.001. HAART exposure was associated with an increased preterm birth rate (15%, or 138 of 946, versus 5%, or seven of 147, in unexposed infants, p = 0.001, with early nevirapine and efavirenz-based regimens having the strongest associations with preterm birth (AOR 5.4, 95% CI 2.1-13.7, p Conclusions In this immunocompromised cohort, in utero HAART exposure was not associated with low birth weight. An association between NNRTI-based HAART and preterm birth was detected, but residual confounding is plausible. More advanced immunosuppression was a risk factor for low birth weight and preterm birth, highlighting the importance of earlier HAART initiation in women to optimize maternal health and improve infant outcomes.

    2012-09-01

    The analysis of the National Child Development Study in the United Kingdom (n = 17,419) replicates some earlier findings and shows that genuine within-family data are not necessary to make the apparent birth-order effect on intelligence disappear. Birth order is not associated with intelligence in between-family data once the number of siblings is statistically controlled. The analyses support the admixture hypothesis, which avers that the apparent birth-order effect on intelligence is an artifact of family size, and cast doubt on the confluence and resource dilution models, both of which claim that birth order has a causal influence on children's cognitive development. The analyses suggest that birth order has no genuine causal effect on general intelligence. PMID:22581677

    Pike, Katharine C; Lucas, Jane S A

    2015-06-01

    In developed countries most preterm births occur between 34 and 37 weeks' gestation. Deliveries during this 'late preterm' period are increasing and, since even mild prematurity is now recognised to be associated with adverse health outcomes, this presents healthcare challenges. Respiratory problems associated with late preterm birth include neonatal respiratory distress, severe RSV infection and childhood wheezing. Late preterm birth prematurely interrupts in utero lung development and is associated with maternal and early life factors which adversely affect the developing respiratory system. This review considers 1) mechanisms underlying the association between late preterm birth and impaired respiratory development, 2) respiratory morbidity associated with late preterm birth, particularly long-term outcomes, and 3) interventions which might protect respiratory development by addressing risk factors affecting the late preterm population, including maternal smoking, early life growth restriction and vulnerability to viral infection.

    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.

Results: Approximately all studies have reported a significant relationship between exposure variable and intended outcomes including eclampsia, preeclampsia, cataract, LBW, PTB, hypertension, sex ratio and length of pregnancy. According to conducted studies, decrease in birth weight is more possible in cold months. Increase in temperature was followed by increase in PTB rate. According to most of the studies, eclampsia and preeclampsia were more prevalent in cold and humid seasons. Two spectrums of heat extent, different seasons of the year, sunlight intensity and season of fertilization were associated with higher rates of PTB, hypertension, eclampsia, preeclampsia, and cataract. Conclusion: Climate change has unfavorable effects on eclampsia, preeclampsia, PTB, and cataract. The findings of this review confirm the crucial importance of the adverse health effects of climate change especially in the perinatal period.

    Effective prevention of preterm birth is one of the unsolved problems in modern medicine. In the Thuringia campaign 2000 based on a simple screening with intravaginal pH self-measurements, adequate medical diagnosis and immediate antimicrobial therapy of genital infection, the rate of newborns methods, do we really have to wait even more decades to come for a prospectively randomized double-blinded almost impracticable study to convince the latest skeptical scientist that we have plenty of evidence-based means to reduce the incidence of premature birth, now, by decreasing infectious morbidity in pregnancy and by the same action childbed fever as well? Insisting scholastically on nothing but the 100 % pure evidence sometimes can hamper innovations and potential benefit. Would a similar caution ever had allowed us for instance to introduce handwashing according to Semmelweis? Good news, the Government of the State of Thuringia has decided this year to reestablish a pH selfcare screening programme. PMID:27146862

    Cesarean birth (CB) is more prevalent in the US-Mexico border region than among all US Hispanics. Comparable data from US and Mexican birth certificates can be used to compare prevalence and identify risk factors on either side of the border. Using 2009 US and Mexican birth certificates, we compared the characteristics of US Hispanic and Mexican CBs in six geographic subgroups: US and Mexican border counties/municipios, US and Mexican non-border counties/municipios and the US and Mexico overall. We also explored cesarean prevalence over time. During 2000-2009, CB rates increased from 22.1 to 31.6 % among US Hispanics and from 25.9 to 37.9 % among Hispanics in the US border region. 2009 rates were 44.5 % in Mexico and 43.1 % in the Mexican border region. In both countries, CB rates were similar for primiparas and multiparas. Higher education, being married and parity >4 were associated with CB in Mexico; being married was associated in the US. Hispanic rates were higher in the US border than non-border region for all age groups. Along the border, cesarean rates for Hispanics were highest in Texas (43.5 %) and neighboring Tamaulipas (49.8 %). Higher cesarean prevalence in Mexico than in US Hispanics, while unexplained, is consistent with high prevalence in some Latin American countries. Higher cesarean prevalence among Hispanics in the US border region than among Hispanics nationwide cannot be explained by maternal age or parity. Medical indications are also unlikely to explain such high rates, which are undesirable for mothers and infants. PMID:24791973

    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

    Full Text Available Abstract Background Birth weight plays an important role in infant mortality and morbidity, childhood development, and adult health. To date there are contradictory results regarding the role of physical activity on birth weight. In addition, it is questioned whether exercise during second and third trimesters of pregnancy might affect gestational age and increase the risk of preterm delivery. Hence, the purpose of this study was to examine the effect of a supervised exercise-program on birth weight, gestational age at delivery and Apgar-score. Methods Sedentary, nulliparous pregnant women (N = 105, mean age 30.7 ± 4.0 years, pre-pregnancy BMI 23.8 ± 4.3 were randomized to either an exercise group (EG, n = 52 or a control group (CG, n = 53. The exercise program consisted of supervised aerobic dance and strength training for 60 minutes, twice per week for a minimum of 12 weeks, with an additional 30 minutes of self-imposed physical activity on the non-supervised week-days. Results There was no statistically significant difference between groups in mean birth weight, low birth weight ( Conclusion Aerobic-dance exercise was not associated with reduction in birth weight, preterm birth rate or neonatal well-being.

    Full Text Available In real life, we can encounter the cluster birth and death process with migration, such as the birth of new individuals and disease in certain place and time. These phenomena can be represented by stochastic model that are considered to be more representatives in capturing natural indications involving the concepts of space and time. In this study, we construct a stochastic model to estimate the population growth in Bogor, West Java, using spatial cluster birth and death methods. It is considered cluster birth and death process, including the effect of migration, with birth and death are Poisson process. In clustering process we use Spatial ‘K’luster Analysis by Tree Edge Removal (SKATER, which is view to considering the influence of the location or the relationship between locations. It has been formulated the stochastic growth model for spatial cluster birth and death process with migration and has been applied in predicting population growth in Bogor, West Java. The estimator that we construct can estimate the population growth with the value of birth rate is not too small.

  6. How Neighborhood Disadvantage Reduces Birth Weight

    Directory of Open Access Journals (Sweden)

    Emily Moiduddin

    2008-06-01

    Full Text Available In this analysis we connect structural neighborhood conditions to birth outcomes through their intermediate effects on mothers’ perceptions of neighborhood danger and their tendency to abuse substances during pregnancy. We hypothesize that neighborhood poverty and racial/ethnic concentration combine to produce environments that mothers perceive as unsafe, thereby increasing the likelihood of negative coping behaviors (substance abuse. We expect these behaviors, in turn, to produce lower birth weights. Using data from the Fragile Families and Child Wellbeing Study, a survey of a cohort of children born between 1998 and 2000 and their mothers in large cities in the United States, we find little evidence to suggest that neighborhood circumstances have strong, direct effects on birth weight. Living in a neighborhood with more foreigners had a positive effect on birth weight. To the extent that neighborhood conditions influence birth weight, the effect mainly occurs through an association with perceived neighborhood danger and subsequent negative coping behaviors. Poverty and racial/ethnic concentration increase a mother’s sense that her neighborhood is unsafe. The perception of an unsafe neighborhood, in turn, associates with a greater likelihood of smoking cigarettes and using illegal drugs, and these behaviors have strong and significant effects in reducing birth weight. However, demographic characteristics, rather than perceived danger or substance abuse, mediate the influence of neighborhood characteristics on birth weight.

    The categories of low birth weigth infants, social vs. racial factors, factors increasing the risk of low birth weight, prevention of low birth weight, social factors in the development of low birth weight children, the influence of social factors vs. other variables, and implications for management are reviewed. In 1948 the World Health Assembly designated children who were born weighing 2500 g or less as "immature" and further stated that a liveborn infant with a period of gestation of less than 37 weeks or specified as "premature" may be considered as the equivalent of an immature event. In 1961 it was recommended that babies weighing 2500 g or less should no longer be referred to as being "premature" and that the concept of "prematurity" in the definition should give way to that of "low birth weight." Intrauterine growth curves for liveborn males and females were devised from data on birth weight and gestational age. Infants born prior to 37 completed weeks of gestation whose weight lies between the 10th and 90th percentiles on such curves may be called preterm with a weight appropriate for gestational age (AGA), whereas infants born after any length of gestation whose birth weight is at or below the 10th percentile may be named hypotrophic or small for gestational age (SGA). On a worldwide scale it has been estimated that about 22 million low birth weight babies, representing roughly 1/6 of all births, are born alive each day. Only about 1 million of them (mostly preterm) are born in developed countries; of the 21 million born in developing areas, roughly 16 million are SGA full-term and not preterm babies. Socioeconomic status appears as 1 of the most important dterminants of the ultimate level of brain function in children of low birth weight, and this is true with respect to neurologic, psychologic, and educational outcome. Social class also has an indirect effect through birth weight, frequency of perinatal brain injury, and other biological variables as

    Full Text Available Birth month in humans is associated with certain biological variables such as reproductive success, health and mortality rate. At the same time, physical attractiveness is regarded as one of the reliable markers of human health and genetic quality, which suggests that female attractiveness may vary according to their season of birth. To test this hypothesis, ratings of females’ photographs from a popular Polish social networking website were analyzed. The sample included 5294 females aged 21-23 years. Results demonstrated that females born in spring (May were rated as being significantly more attractive than those born in autumn (September and November.

  18. Kinetics of aggregation growth with competition between catalyzed birth and catalyzed death

    International Nuclear Information System (INIS)

    An aggregation growth model of three species A, B and C with the competition between catalyzed birth and catalyzed death is proposed. Irreversible aggregation occurs between any two aggregates of the like species with the constant rate kernels In(n = 1,2,3). Meanwhile, a monomer birth of an A species aggregate of size k occurs under the catalysis of a B species aggregate of size j with the catalyzed birth rate kernel K(k,j) = Kkjv and a monomer death of an A species aggregate of size k occurs under the catalysis of a C species aggregate of size j with the catalyzed death rate kernel L(k,j)=Lkjv, where v is a parameter reflecting the dependence of the catalysis reaction rates of birth and death on the size of catalyst aggregate. The kinetic evolution behaviours of the three species are investigated by the rate equation approach based on the mean-field theory. The form of the aggregate size distribution of A species ak(t) is found to be dependent crucially on the competition between the catalyzed birth and death of A species, as well as the irreversible aggregation processes of the three species: (1) In the v k(t) satisfies the conventional scaling form; (2) In the v ≥ 0 case, the competition between the catalyzed birth and death dominates the process. When the catalyzed birth controls the process, ak(t) takes the conventional or generalized scaling form. While the catalyzed death controls the process, the scaling description of the aggregate size distribution breaks down completely

    Historically low breast cancer incidence rates among Asian women have risen worldwide; purportedly due to the adoption of a "Western" life style among younger generations (i.e., the more recent birth cohorts). However, no study has simultaneously compared birth cohort effects between both younger and older women in different Asian and Western populations. Using cancer registry data from rural and urban China, Singapore and the United States (1990-2008), we estimated age-standardized incidence rates (ASR), annual percentage change (EAPC) in the ASR, net drifts, birth cohort specific incidence rates and cohort rate ratios (CRR). Younger (30-49 years, 1943-1977 birth cohorts) and older women (50-79 years; 1913-1957 birth cohorts) were assessed separately. CRRs among Chinese populations were estimated using birth cohort specific rates with US non-Hispanic white women (NHW) serving as the reference population with an assigned CRR of 1.0. We observed higher EAPCs and net drifts among those Chinese populations with lower ASRs. Similarly, we observed the most rapidly increasing cohort-specific incidence rates among those Chinese populations with the lowest baseline CRRs. Both trends were more significant among older than younger women. Average CRRs were 0.06-0.44 among older and 0.18-0.81 among younger women. Rapidly rising cohort specific rates have narrowed the historic disparity between Chinese and US NHW breast cancer populations particularly in regions with the lowest baseline rates and among older women. Future analytic studies are needed to investigate risk factors accounting for the rapid increase of breast cancer among older and younger women separately in Asian populations. PMID:26992019

    The goal of this study was to evaluate the relation between kittens' birth weights and biometrical factors from the kittens and the mother during pregnancy. Knowing fetal birth weight could help in detecting abnormalities before parturition. A Caesarean-section or a postnatal management plan could be scheduled. Consequently, the neonatal mortality rate should be decreased. We used ultrasonographic measurements of femur length (FL) or fetal biparietal diameter (BPD), pregnancies, and maternal factors to obtain a model of prediction. For this purpose, linear mixed-effects models were used because of random effects (several fetuses for one queen and a few paired measurements) and fixed effects (litter size, pregnancy rank, weight, wither height, and age of the queen). This study was performed in 24 purebred queens with normal pregnancies and normal body conditions. Queens were scanned in the second half of pregnancy, using a micro-convex probe. They gave birth to 140 healthy kittens whose mean birth weight was 104 g (ranged 65 to 165 g). No correlation between the birth weight and the age of the queen, as a maternal factor alone, was observed. But the birth weight was found to be inversely proportional to the pregnancy rank and the litter size. Moreover, birth weight increased when the weight and wither height of queen increased. BPD and FL increased linearly during pregnancy so a model was used to estimate mean birth weight. Using this model, we found a correlation between mean birth weights and an association of parameters: maternal factors (wither height and age), and litter size. PMID:21820718

  3. Birth Weight, Gestational Age, and Infantile Colic

    Milidou, Ioanna; Søndregaard, Charlotte; Jensen, Morten Søndergaard;

    Background Infantile colic is a condition of unknown origin characterized by paroxysms of crying during the first months of life. A few studies have identified low birth weight (BW) as a risk factor among infants born at term, while the association between gestational age (GA) and infantile colic...... GA, low BW was associated with infantile colic only in infants born at term (gestational weeks 37-41), but not in pre- or post-term infants. Conclusion The results indicate that low birth weight and preterm birth are independently associated with infantile colic. After adjusting for gestational age......, low birth weight increased the risk of infantile colic in children born at term (gestational weeks 37-41)....

    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. PMID:27007730

    Full Text Available Objective: Preterm neonates were approximately 70% of total low birth weight infants in developed countries. The aim of this study is to evaluate the low birth weight neonates who were hospitalized in the neonatal unit of our hospital between the years 2010-2011, retrospectively. Methods: 626 infants that born with under 2500 gram were enrolled to the study. Family history, natal, prenatal, postnatal, maternal and demographic features and risk factors were recorded retrospectively. Results: Mother giving birth age was 21-35 years, gestational age was at 33 weeks and birth weight was found 2001-2500 gram mostly and the mortality rate was found 29.7% in our study. Maternal age, multipl pregnancy ratio, place of birth, birth presentation, duration of hospitalization, causes of premature birth and mortality rate is found statistically significant difference between low birth weight infants when comparing with birth weight (p<0.05. The most common cause of premature birth was preeclampsia-eclampsia in all infants while oligohydramnios was mostly found in ≤1000 gram infants. Respiratory distress and convulsion in the 2001-2500 g infants, hyperbilirubinemia in the 1501-2000 gram infants and required mechanical ventilation in the ≤1000 gram infants were found significantly higher (p<0.05. Conclusion: Improving the educational level of the society, ensuring adequate prenatal monitoring, establishment of appropriate and adequate neonatal intensive care unit, following out delivery of premature at neonatal intensive care unit centers, appropriate transporting should be done, identifying the common risks such as sepsis and respiratory distress syndrome for mortality causes and taken measures againts them are serious importance for the prevention of premature birth.

    In this paper, we consider birth-death processes on a tree T and we are interested when it is regular, recurrent and ergodic (strongly, exponentially). By constructing two corresponding birth death processes on Z+, we obtain computable conditions sufficient or necessary for that (in many cases, these two conditions coincide). With the help of these constructions, we give explicit upper and lower bounds for the Dirichlet eigenvalue λ0. At last, some examples are investigated to justify our results.

  7. Effect of Hurricane Katrina on Low Birth Weight and Preterm Deliveries in African American Women in Louisiana, Mississippi, and Alabama

    Directory of Open Access Journals (Sweden)

    Chau-Kuang Chen

    2012-04-01

    Full Text Available Using three modeling techniques (GLR, GEP, and GM, the effect of Hurricane Katrina on low birth weight and preterm delivery babies for African American women is examined in Louisiana, Mississippi and Alabama. The study results indicate that risk factors associated with low birth weight and preterm delivery for American African women include unemployment and percent of mothers between the ages of 15-19. Among White women, ages 15-19, risk factors included poverty rate, median household income, and total birth rate. The GMs performed accurate predictions with increasing low birth weight and preterm delivery trends for African American women in the Gulf Coast states and other U.S. states, and decreasing low birth weight and preterm delivery trends for their White counterparts in the same state locations. Data presented between 2007-2010 show low birth weight and preterm delivery for White women as a decreasing tendency while adverse birth outcomes for African American women exhibited a monotonically increasing trend. The empirical findings suggest that health disparities will continue to exist in the foreseeable future, if no effective intervention is taken. The models identify risk factors that contribute to adverse birth outcomes and offer some insight into strategies and programs to address and ameliorate these effects.

  8. Evolutionary ecology of human birth sex ratio under the compound influence of climate change, famine, economic crises and wars.

    1. Human sex ratio at birth at the population level has been suggested to vary according to exogenous stressors such as wars, ambient temperature, ecological disasters and economic crises, but their relative effects on birth sex ratio have not been investigated. It also remains unclear whether such associations represent environmental forcing or adaptive parental response, as parents may produce the sex that has better survival prospects and fitness in a given environmental challenge. 2. We examined the simultaneous role of wars, famine, ambient temperature, economic development and total mortality rate on the annual variation of offspring birth sex ratio and whether this variation, in turn, was related to sex-specific infant mortality rate in Finland during 1865-2003. 3. Our findings show an increased excess of male births during the World War II and during warm years. Instead, economic development, famine, short-lasting Finnish civil war and total mortality rate were not related to birth sex ratio. Moreover, we found no association between annual birth sex ratio and sex-biased infant mortality rate among the concurrent cohort. 4. Our results propose that some exogenous challenges like ambient temperature and war can skew human birth sex ratio and that these deviations likely represent environmental forcing rather than adaptive parental response to such challenges.

  9. Biannual birth pulses allow filoviruses to persist in bat populations.

    2015-03-22

    Filoviruses Ebolavirus (EBOV) and Marburgvirus (MARV) cause haemorrhagic fevers with high mortality rates, posing significant threats to public health. To understand transmission into human populations, filovirus dynamics within reservoir host populations must be understood. Studies have directly linked filoviruses to bats, but the mechanisms allowing viral persistence within bat populations are poorly understood. Theory suggests seasonal birthing may decrease the probability of pathogen persistence within populations, but data suggest MARV may persist within colonies of seasonally breeding Egyptian fruit bats, Rousettus aegyptiacus. I synthesize available filovirus and bat data in a stochastic compartmental model to explore fundamental questions relating to filovirus ecology: can filoviruses persist within isolated bat colonies; do critical community sizes exist; and how do host-pathogen relationships affect spillover transmission potential? Synchronous annual breeding and shorter incubation periods did not allow filovirus persistence, whereas bi-annual breeding and longer incubation periods, such as reported for Egyptian fruit bats and EBOV in experimental studies, allowed persistence in colony sizes often found in nature. Serological data support the findings, with bats from species with two annual birth pulses more likely to be seropositive (odds ratio (OR) 4.4, 95% confidence interval (CI) 2.5-8.7) than those with one, suggesting that biannual birthing is necessary for filovirus persistence.

    Approximately 1% of American women give birth at home and face substantial obstacles when they make this choice. This study describes the reasons that women in the United States choose home birth. A qualitative descriptive secondary analysis was conducted in a previously collected dataset obtained via an online survey. The sample consisted of 160 women who were US residents and planned a home birth at least once. Content analysis was used to study the responses from women to one essay question: "Why did you choose home birth?" Women who participated in the study were mostly married (91%) and white (87%). The majority (62%) had a college education. Our analysis revealed 508 separate statements about why these women chose home birth. Responses were coded and categorized into 26 common themes. The most common reasons given for wanting to birth at home were: 1) safety (n = 38); 2) avoidance of unnecessary medical interventions common in hospital births (n = 38); 3) previous negative hospital experience (n = 37); 4) more control (n = 35); and 5) comfortable, familiar environment (n = 30). Another dominant theme was women's trust in the birth process (n = 25). Women equated medical intervention with reduced safety and trusted their bodies' inherent ability to give birth without interference. PMID:19249657

    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

    The effects of chemical activation on birth efficiency of cloned pigs were studied by investigating the developmental process from porcine oocyte activation to birth of cloned pigs. Three different activation methods were used: (i) Electroporation (Ele); (ii) Ele followed by incubation with 6-dimethylaminopurine (6-DMAP); and (iii) Ele followed by a treatment with cycloheximide (CHX). In experiment 1, the rates of cleavage, developmental rates and cell number of porcine parthenogenetic (PA) embryos were investigated in the three treatment groups. In experiment 2, NT embryos produced by the three different activation treatments were compared for the rates of cleavage, development and cell number. Finally, the effects of Eie and Ele+CHX activation methods on birth efficiency of cloned pigs were compared. The activated oocytes treated by combination activation generally showed a higher (P<0.05) blastocyst rate and produced more expanded blastocysts than oocytes activated with Ele. The rates of cleavage and total cell number of parthenotes were not significantly different. Parthenogenetic embryos activated with 6-DMAP developed into blastocyst and expanded blsstocyst stages at a significantly (P<0.05) higher rate than those treated with Ele, but the developmental capability was dramatically decreased In NT embryos. With the CHX activation method, the NT embryo blastocyst rate was substantially (P<0.05) increased although the production of expanded blastocysts was not significantly different from that by the other two methods. The birth rate of cloned pigs increased in the CHX group, though the rate was not significantly different from Ele. The effects of season on developmental rate of the porcine PA embryos and birth rate of cloned pigs were also examined in our study. Porcine oocytes collected in the spring had higher developmental capabilities than those collected in the winter. However, no difference in birth rate of the cloned pigs was found between the oocytes

  18. Obstetric Care Consensus No. 4: Periviable Birth.

    Science.gov (United States)

    2016-06-01

    Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth. These include, but are not limited to, nonmodifiable factors (eg, fetal sex, weight, plurality), potentially modifiable antepartum and intrapartum factors (eg, location of delivery, intent to intervene by cesarean delivery or induction for delivery, administration of antenatal corticosteroids and magnesium sulfate), and postnatal management (eg, starting or withholding and continuing or withdrawing intensive care after birth). Antepartum and intrapartum management options vary depending upon the specific circumstances but may include short-term tocolytic therapy for preterm labor to allow time for administration of antenatal steroids, antibiotics to prolong latency after preterm premature rupture of membranes or for intrapartum group B streptococci prophylaxis, and delivery, including cesarean delivery, for concern regarding fetal well-being or fetal malpresentation. Whenever possible, periviable births for which maternal or neonatal intervention is planned should occur in centers that offer expertise in maternal and neonatal care and the needed infrastructure, including intensive care units, to support such services. This document describes newborn outcomes after periviable birth, provides current evidence and recommendations regarding interventions in this setting, and provides an outline for family counseling with the goal of

    Full Text Available INTRODUCTION: Cerebral palsy ( CP is a group of permanent movement disorders that appear in early childhood. Preterm birth is the birth of baby before 37 completed weeks, a full term birth is birth at 37 to 42 weeks of gestation . AIM: To show the extent of association of preterm deliveries as a risk factor in development of cerebral palsy. MATERIALS AND METHODS: This r etrospective cohort study was conducted by eliciting history from the mothers of 99 cerebral palsy children who w ere treated in Rani Chandra Mani Devi Hospital, Visakhapatnam, Andhra Pradesh, India. De tailed history was taken from the mothers of 99 cerebral palsy children who were treated in this hospital. History regarding the period of gestation at which the child was born (preterm or full term, any previous history of pre - term delivery or abortions, was obtained from the mothers and the data analyzed . RESULTS: From this study it was observed the proportional association of pre - term births to cerebral palsy is 33 out 99 i.e., about 33.33%, Of these 33 cerebral palsy children highest association being with birth at 28 wks gestation (51 %. This study also shows th at the mothers with a previous history of preterm delivery have 14.4 times higher risk of subsequent pre term delivery; those with previous history of abortions have 5.7 times risk of pre - term delivery than mothers without such history. CONCLUSION: From th is study it was concluded that the pre - term birth plays a major role as a risk factor in the development of cerebral palsy with mothers having previous pre term delivery and previous abortions adding further to this risk.

  20. Universality in random-walk models with birth and death

    International Nuclear Information System (INIS)

    Models of random walks are considered in which walkers are born at one site and die at all other sites. Steady-state distributions of walkers exhibit dimensionally dependent critical behavior as a function of the birth rate. Exact analytical results for a hyperspherical lattice yield a second-order phase transition with a nontrivial critical exponent for all positive dimensions D≠2, 4. Numerical studies of hypercubic and fractal lattices indicate that these exact results are universal. This work elucidates the adsorption transition of polymers at curved interfaces. copyright 1995 The American Physical Society

    Historically, recommendations for neonatal resuscitation were largely based on dogma, but there is renewed interest in performing resuscitation studies at birth. The emphasis for resuscitation following birth asphyxia is administering effective ventilation, as adequate lung aeration leads not only to an increase in oxygenation but also increased pulmonary blood flow and heart rate. To aerate the lung, an initial sustained inflation can increase heart rate, oxygenation, and blood pressure recovery much faster when compared with standard ventilation. Hyperoxia should be avoided, and extra oxygen given to restore cardiac function and spontaneous breathing should be titrated based on oxygen saturations. PMID:27524447

    The aims of this study are to assess the impact of Austria's anonymous birth law from the time relevant statistical records are available and to evaluate the use of hatches versus anonymous hospital delivery. This study is a complete census of police-reported neonaticides (1975-2012) as well as anonymous births including baby hatches in Austria during 2002-2012. The time trends of neonaticide rates, anonymous births and baby hatches were analysed by means of Poisson and logistic regression model. Predicted and observed rates were derived and compared using a Bayesian Poisson regression model. Predicted numbers of neonaticides for the period of the active awareness campaign, 2002-2004, were more than three times larger than the observed number (p = 0.0067). Of the 365 women who benefitted from this legislation, only 11.5 % chose to put their babies in a baby hatch. Since the law was introduced, a significant decreasing tendency of numbers of anonymous births (p = 047) was observed, while there was significant increase of neonaticide rates (p = 0.0001). The implementation of the anonymous delivery law is associated with a decrease in the number of police-reported neonaticides. The subsequent significantly decreasing numbers of anonymous births with an accompanying increase of neonaticides represents additional evidence for the effectiveness of the measure. PMID:26267063

  3. Explaining racial disparities in adverse birth outcomes: unique sources of stress for Black American women.

    The infant mortality rate for Black Americans in the US is more than twice the rate for White Americans, with similar racial disparities existing in rates of low birthweight and preterm delivery. Survivors of these adverse birth outcomes have poorer development and health in infancy, childhood, and adulthood. Increasingly, evidence suggests that maternal stress is an important risk factor for adverse birth outcomes. We offer a novel perspective on racial disparities in birth outcomes suggesting that Black American women are subject to unique sources of stress throughout their lives and particularly during pregnancy based on their multiple identities as women, Black, and pregnant. We draw on interdisciplinary work to examine three unique sources of stress for Black American women that elevate their risk for adverse birth outcomes: 1) abuses of Black American women by the medical system and issues of power in obstetrics that disadvantage Black American women; 2) contradictory societal pressures exerted on Black American women about whether they should have children; and 3) historical and contemporary stereotypes about Black American women related to sexuality and motherhood. We discuss implications of this analysis, including applications to research and intervention. Developing a better understanding of the experience of Black American women during pregnancy and throughout their lives offers insight into ways to reduce racial disparities in adverse birth outcomes and their lifelong consequences.

    This study assessed the reliability of birth certificate data related to birth defects in Brazil's Live Birth Information System (SINASC). We selected 24 maternity hospitals in the Unified National Health System (SUS) and compared the reports of birth defects from birth certificates with medical records of mothers and live born infants in the city of Rio de Janeiro for the year 2004. After transposing the data to a specific form, the birth defects were coded by types and organ systems and compared to the SINASC data. The most commonly affected organs involved the central nervous and musculoskeletal systems. Agreement was more than 50% for the digestive, genitourinary, and musculoskeletal systems and chromosomal anomalies. Prevalence-adjusted kappa varied according to 2 or 3-digit ICD-10 analysis, with better results for the musculoskeletal, digestive, and genitourinary systems and congenital anomalies, and worse for the central nervous and cardio-circulatory systems, eye, neck, and ear malformations, and cleft lip and palate. The results were unsatisfactory, suggesting the need for more investments to train the persons responsible for completing birth certificates in maternity hospitals and develop a model for coding birth defects on these documents.

Antenatal examinations are important in selection for trial of labor, while birth management can be difficult when the patients present at emergency condition. But there is an increased chance of vaginal birth with advanced cervical dilation. This study attempts to evaluate factors associated with success of vaginal birth after cesarean section and to compare the maternal and perinatal outcomes between vaginal birth after cesarean section and intrapartum cesarean section in patients who were admitted to hospital during the active or second stage of labor. A retrospective evaluation was made from the results of 127 patients. Cesarean section was performed in 57 patients; 70 attempted trial of labor. The factors associated with success of vaginal birth after cesarean section were investigated. Maternal and neonatal outcomes were compared between the groups. Vaginal birth after cesarean section was successful in 55% of cases. Advanced cervical opening, effacement, gravidity, parity, and prior vaginal delivery were factors associated with successful vaginal birth. The vaginal birth group had more complications (P<0.01, but these were minor. The rate of blood transfusion and prevalence of changes in hemoglobin level were similar in both groups (P>0.05. In this study, cervical opening, effacement, gravidity, parity, and prior vaginal delivery were important factors for successful vaginal birth after cesarean section.

    Birth defects are one of the most common adverse birth outcomes, which create a heavy economic burden to the country, society and family. And they are also one of the biggest problems facing public health today. Polycyclic aromatic hydrocarbons (PAHs) are a group of toxic pollutants existing in the environment widely, resulting from incomplete organic matter combustion, and can be taken into the body through various ways including the digestive tract, respiratory tract and so on. Recent researches suggest that the exposure of PAHs may be associated with various birth defects, while the special mechanism isn't very clear. This paper is a review of the relationship between PAHs and birth defects from the aspects of epidemiological data, experimental evidence on animals, which indicates that exposure of PAHs during pregnancy may be associated with birth defects including congenital heart defects, neural tube defects and cleft lip/plate. Furthermore, we explored the possible mechanism, including oxidative stress, oxidative damage and the changes of signal transduction pathway in order to provide some recommendations and suggestions on the future work.

    Full Text Available Ethiopia childhood mortality has continued to decline although at a swift pace. The drop in urban childhood mortality decline, duration of breastfeeding is the principle reason for the overall decline in mortality trends in Ethiopia. Data from the Ethiopian Demographic and Health Surveys 2000 and 2005 were used. Indirect estimation of Brass and Trussells methods were adopted. Selected demographic and socio-economic variables were included in the analysis with statistically significant effects. Findings clearly show neonatal and post neonatal mortality decline gradually. Even though, Ethiopia childhood mortality rates are still high. The result shows less than 2 years birth interval have higher infant mortality rates than higher birth interval (113 deaths per 1000. The proper spacing of births allows more time for childcare to make more maternal resources available for the care of the child and mother. Therefore, further research is urgent for regional level and national level investigation.

    2002-08-01

    An association between deficit schizophrenia and summer birth has previously been reported. The authors attempted to replicate this association in a population-based study of incident cases of psychosis in the autonomous region of Cantabria, in northern Spain. Schizophrenia patients were categorized into deficit (N = 22) and nondeficit (N = 55) groups, and the pattern in the two groups was compared. After accounting for the variance due to disorganization, hallucinations and delusions, and demographic variables, deficit schizophrenia had a significant association with summer birth; this association did not depend on a single definition of summer. For instance, among the deficit patients, 59% were born from May to August, in contrast to 18% of nondeficit patients and 34% of the general population. These results confirm the association between summer birth in the Northern Hemisphere and deficit as opposed to nondeficit schizophrenia. The existence of a different risk factor for the two groups suggests a difference in etiology and pathophysiology. PMID:12193837

  16. Myelination in very low birth weight infants

    International Nuclear Information System (INIS)

    The prognostic significance of cerebral myelination was evaluated with magnetic resonance imaging (MRI) in very low birth weight infants. Myelination was graded in two specified sites, optic radiation and corpus callosum, based on the stages of normal term babies and healthy premature infants. The subjects were 30 preterm infants weighing less than 1,500 gm at birth. MRI was performed at 4 to 7 months (corrected age). The normal myelination stage was seen in 18 cases, while a delayed stage was noticed in 12 cases. In the normal myelination group, only 1 case (6%) had handicaps. In the delayed myelination group, 8 cases (67%) had handicaps. Our results showed that delayed myelination was closely related to a poor prognosis. We believe that MRI would be a very good imaging modality for predicting the outcome of very low birth weight infants, particularly in terms of evaluation of myelination. (author)

    The problem of preterm birth continues to pose one of the most significant research challenges that we face due to its immense scope and complexity. With evidence that 95% of cases of spontaneous preterm birth are intractable to current interventions, our best hope in resolving this problem may lie in new, innovative ideas. Novel approaches to researching preterm birth are currently underway, building upon our prior discoveries and probing into the unknown on multiple fronts. Here we discuss some of the major focuses of future investigation that provide a promising outlook for discovery, including advanced techniques to evaluate the cervix, new strategies to identify the role of the microbiome, and advances in molecular and epigenetic-based research.

    Currently, 60 million women of reproductive age (18-44 years old) worldwide, and approximately 3 million American women have diabetes mellitus, and it has been estimated that this number will double by 2030. Pregestational diabetes mellitus (PGD) is a significant public health problem that increases the risk for structural birth defects affecting both maternal and neonatal pregnancy outcome. The most common types of human structural birth defects associated with PGD are congenital heart defects and central nervous system defects. However, diabetes can induce birth defects in any other fetal organ. In general, the rate of birth defects increases linearly with the degree of maternal hyperglycemia, which is the major factor that mediates teratogenicity of PGD. Stringent prenatal care and glycemic control are effective means to reduce birth defects in PGD pregnancies, but cannot reduce the incidence of birth defects to the rate of that is seen in the nondiabetic population. Studies in animal models have revealed that PGD induces oxidative stress, which activates cellular stress signalling leading to dysregulation of gene expression and excess apoptosis in the target organs, including the neural tube and embryonic heart. Activation of the apoptosis signal-regulating kinase 1 (ASK1)-forkhead transcription factor 3a (FoxO3a)-caspase 8 pathway causes apoptosis in the developing neural tube leading to neural tube defects (NTDs). ASK1 activates the c-Jun-N-Terminal kinase 1/2 (JNK1/2), which leads to activation of the unfolded protein response and endoplasmic reticulum (ER) stress. Deletion of the ASK1 gene, the JNK1 gene, or the JNK2 gene, or inhibition of ER stress by 4-Phenylbutyric acid abrogates diabetes-induced apoptosis and reduces the formation of NTDs. Antioxidants, such as thioredoxin, which inhibits the ASK1-FoxO3a-caspase 8 pathway or ER stress inhibitors, may prevent PGD-induced birth defects. PMID:25897357

The medical files of all neonates weighing ≤1500 g, born in Vali-e-Asr hospital (2001-2004 were studied. Two groups of neonates (living and dead were compared up to the time of hospital discharge or death. A total of 317 neonates were enrolled. A meaningful relationship existed between occurrence of death and low gestational age (P=0.02, low birth weight, lower than 1000 g (P=0.001, Apgar score <6 at 5th minutes (P=0.001, resuscitation at birth (P=0.001, respiratory distress syndrome (P=0.001 need for mechanical ventilation (P=0.001, neurological complications (P=0.001 and intraventricular hemorrhage (P=0.001. Regression analysis indicated that each 250 g weight increase up to 1250 g had protective effect, and reduced mortality rate. The causes of death of those neonates weighting over 1250 g should be sought in factors other than weight. Survival rate was calculated to be 80.4% for neonates weighing more than 1000 g. The most important high risk factors affecting mortality of neonates are: low birth weight, need for resuscitation at birth, need for ventilator use and intraventricular hemorrhage.

    The concepts of bi-immigration birth and death density matrix in random environment and bi-immigration birth and death process in random environment are introduced. For any bi-immigration birth and death matrix in random environment Q(θ)with birth rate λ< death rate μ, the following results are proved, (1) there is an unique q-process in random environment, -P(θ*(0);t) = (-p(θ*(0);t,i,j),i,j ≥ 0), which is ergodic, that is, limt→∞ -p(θ*(0);t,i,j) = -π(θ*(0);j) ≥ 0 does not depend on i ≥ 0 and Σj≥0 -π(θ*(0);j) = 1, (2) there is a bi-immigration birth and death process in random environment (X* = {Xt, t ≥ 0}, ξ* = {ξt, t ∈ (-∞, ∞)}) with random transition matrix -P(θ* (0); t) such that X* is a strictly stationary process.

    Full Text Available Background Candida colonization is a major risk factor for invasive candidiasis in premature infants in the neonatal intensive care unit (NICU. Objectives The purpose of this study was to determine the rate, risk factors, and sources of colonization in low birth weight (LBW and very low birth weight (VLBW infants in an NICU. Patients and Methods All cases were classified in to 1 of 2 groups: LBW and VLBW. A questionnaire that collected demographic data was completed for each case. Swabs were obtained from the ear, umbilicus, and rectum, as well as catheters, tracheal tubes, and nasogastric tubes. Samples were cultured on Sabouraud dextrose agar. The data were analyzed using SPSS software. A P value < 0.05 was considered significant. Results A total of 102 cases were examined in this study. The mean weight of the infants was 1720 ± 474 gr (range 850 - 2500 gr. Positive Candida cultures were isolated in 19 (31.7% cases in the LBW group and 20 (47.6% cases in the VLBW group. In addition, 36 (35.3% cases showed signs of sepsis. The mortality rate was 1.7% (n = 1. The umbilicus and rectum were the most common sites for Candida colonization in both groups. The analysis also indicated that the duration of hospitalization, prolonged use of corticosteroids, central venous catheters, total parenteral nutrition, and mechanical ventilation were associated with candidiasis infection in VLBW infants while prolonged use of corticosteroids and central venous catheters were major risk factors associated with candidiasis infection in LBW infants. Conclusions These results show that maturity and birth weight are related to a decrease in the risk of developing a candidiasis infection.

    In the Netherlands women with low risk pregnancies can choose whether they want to give birth at home or in hospital, under the care of their own primary caregiver. The majority of these women prefer to give birth at home, but over the last few decades an increasing number of low risk women have chosen a hospital birth, leaving hospital with their baby shortly after delivery. As both this trend and its effects have not been extensively investigated, a study was designed to examine the determi...

    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-birt...

    Full Text Available OBJECTIVE: Infants born small for gestational age (SGA or preterm have increased rates of perinatal morbidity and mortality. Stressful events have been suggested as potential contributors to preterm birth (PB and low birth weight (LBW. We studied the effect of the 2008 economic collapse in Iceland on the risks of adverse birth outcomes. STUDY DESIGN: The study population constituted all Icelandic women giving birth to live-born singletons from January 1(st 2006 to December 31(st 2009. LBW infants were defined as those weighing <2500 grams at birth, PB infants as those born before 37 weeks of gestation and SGA as those with a birth weight for gestational age more than 2 standard deviations (SD's below the mean according to the Swedish fetal growth curve. We used logistic regression analysis to estimate odds ratios [OR] and corresponding 95 percent confidence intervals [95% CI] of adverse birth outcomes by exposure to calendar time of the economic collapse, i.e. after October 6(th 2008. RESULTS: Compared to the preceding period, we observed an increased adjusted odds in LBW-deliveries following the collapse (aOR = 1.24, 95% CI [1.02, 1.52], particularly among infants born to mothers younger than 25 years (aOR = 1.85, 95% CI [1.25, 2.72] and not working mothers (aOR = 1.61, 95% CI [1.10, 2.35]. Similarly, we found a tendency towards higher incidence of SGA-births (aOR = 1.14, 95% CI [0.86, 1.51] particularly among children born to mothers younger than 25 years (aOR = 1.87, 95% CI [1.09, 3.23] and not working mothers (aOR = 1.86, 95% CI [1.09, 3.17]. No change in risk of PB was observed. The increase of LBW was most distinct 6-9 months after the collapse. CONCLUSION: The results suggest an increase in risk of LBW shortly after the collapse of the Icelandic national economy. The increase in LBW seems to be driven by reduced fetal growth rate rather than shorter gestation.

    OBJECTIVE: We examined the association between occupational lifting during pregnancy and risk of fetal death and preterm birth using a job exposure matrix (JEM). METHODS: For 68,086 occupationally active women in the Danish National Birth Cohort, interview information on occupational lifting was...... the JEM. We used Cox regression models with gestational age as underlying time variable and adjustment for covariates. RESULTS: We observed 2,717 fetal deaths and 3,128 preterm births within the study cohort. No exposure-response relation was observed for fetal death, but for women with a prior fetal...... death, we found a hazard ratio (HR) of 2.87 (95% CI 1.37, 6.01) for stillbirth (fetal death ≥22 completed gestational weeks) among those who lifted >200 kg/day. For preterm birth, we found an exposure-response relation for primigravid women, reaching a HR of 1.43 (95% CI 1.13, 1.80) for total loads >200...
