产妇孕期被动吸烟与低出生体重症例对照研究 总被引:5,自引:0,他引:5
为分析母亲孕期被动吸烟与低出生体重的关系,采用群体匹配病例对照研究方法,对1999年3月-2000年4月间在沈阳市妇婴医院等14家医院分娩的非主动吸烟的产妇孕期被动吸烟情况与低出生体重关系进行分析。结果表明:孕期被动吸烟可能是低出生体重危险因素,且孕期被动吸烟的时间与低出生体重发生存在剂量反应关系(x^2趋势=32.42;P<0.01)。在控制产女不良孕产史等因素后,被动吸烟孕妇分娩出低出生体重儿的危险性为非被动吸烟孕妇的3.176倍(OR95%CI,1.868-5.401),且被动吸烟与孕妇文化程度对出生体重可能存在协同作用(协同作用指数为3.16)。 相似文献

The acculturation effect of immigrant women on birth outcomes varies by race. We examined birth outcomes of three groups of births for the period 1995-2004, USA births to the USA-born Korean mothers, USA births to the non-USA-born Korean mothers, and births in Korea. In singleton USA births to both Korean parents, average birth weight was 3,294 g for the USA-born Korean mothers and 3,323 g for the non-USA-born Korean mothers. However, this difference was not significant, once controlled for other maternal sociodemographic, obstetric and medical factors. Low birth weight and prematurity prevalence were not different by maternal nativity between these two singleton groups. Average birth weight of all births including multiplets in Korea was 3,270 g, compared to 3,297 g for all USA-born infants including multiplets and births either to both or one Korean parents. This difference might have reflected a significantly lower educational attainment of mothers in Korea compared to Korean mothers in the USA. Low birth weight rate was consistently lower in infants born in Korea compared to the USA-born, but this difference became less, 4.2% and 4.6% respectively by 2004. These observations suggest that in the USA acculturation effect of Korean immigrants on birth outcomes is negligible. 相似文献

BACKGROUND. Although the risk of very low birth weight (less than 1500 g) is more than twice as high among blacks as among whites in the United States, the clinical conditions associated with this disparity remain poorly explored. METHODS AND RESULTS. We reviewed the medical records of over 98 percent of all infants weighing 500 to 1499 g who were born in Boston during the period 1980 through 1985 (687 infants), in St. Louis in 1985 and 1986 (397 infants), and in two health districts in Mississippi in 1984 and 1985 (215 infants). The medical records of the infants' mothers were also reviewed. These data were linked to birth-certificate files. During the study periods, there were 49,196 live births in Boston, 16,232 in St. Louis, and 16,332 in the Mississippi districts. The relative risk of very low birth weight among black infants as compared with white infants ranged from 2.3 to 3.2 in the three areas. The higher proportion of black infants with very low birth weights was related to an elevated risk in their mothers of major conditions associated with very low birth weight, primarily chorioamnionitis or premature rupture of the amniotic membrane (associated with 38.0 percent of the excess proportion of black infants with very low birth weights [95 percent confidence interval, 31.3 to 45.4 percent]); idiopathic preterm labor (20.9 percent of the excess [95 percent confidence interval, 16.0 to 26.4 percent]); hypertensive disorders (12.3 percent [95 percent confidence interval, 8.6 to 16.6]); and hemorrhage (9.8 percent [95 percent confidence interval, 5.5 to 13.5]). CONCLUSIONS. The higher proportion of black infants with very low birth weights is associated with a greater frequency of all major maternal conditions precipitating delivery among black women. Reductions in the disparity in birth weight between blacks and whites are not likely to result from any single clinical intervention but, rather, from comprehensive preventive strategies. 相似文献

Evidence from the Philippines suggests that, compared to Whites, infants born to Filipino women are more likely to be low birth weight. A paucity of information is available regarding birth outcomes of U.S.-born Filipinos. Using 1979–1987 Hawaii vital record data on single live births to resident mothers, this study compares the maternal characteristics and pregnancy outcomes of White and Filipino mothers, Filipino mothers were significantly more likely to be <18 years of age and single, and have lower educational attainment and less adequate utilization of prenatal care. Significantly higher percentages of very preterm, preterm, very low birth weight, low birth weight, and small for gestational age infants were found for Filipinos. The birth weight-specific neonatal mortality rates for Filipinos compared favorably to Whites except at the high end of the birth weight distribution. After taking into account maternal sociodemographic risk and prenatal care factors in a logistic regression, a significant ethnic difference in low birth weight persisted but was not found for neonatal mortality. These data may suggest that similar neonatal mortality rates among ethnic groups may be possible in the face of persistent birth weight distribution differences and add to the growing evidence that a single standard of low birth weight may be inappropriate as an universal indicator of health status risk in a multi-ethnic population. © 1993 Wiley-Liss, Inc. 相似文献

Racial differences in low birth weight. Trends and risk factors 总被引:19,自引:0,他引:19
To identify the risk factors responsible for differences in birth weight between blacks and whites, we investigated the effects of four maternal characteristics (age, parity, marital status, and education) on rates of very low birth weight (less than 1500 g) and moderately low birth weight (between 1500 and 2500 g). Using 1983 national data, we found that the black:white rate ratio was 3.0 for very low birth weight and 2.3 for moderately low birth weight. The four maternal factors had directionally similar but quantitatively different effects on very low and moderately low birth weight among blacks and whites. Furthermore, the racial differences in infants' birth weights were greater among low-risk than among high-risk mothers, especially for very low birth weight (black:white ratios of 3.4 and 1.7, respectively). We also examined secular trends in the rates of low birth weight among blacks and whites. Between 1973 and 1983, births of infants with moderately low birth weights decreased more among whites than among blacks, whereas births of infants with very low birth weights increased among blacks and decreased among whites. Fifteen percent of the decline in the rate of moderately low birth weight among whites could be attributed to favorable changes in maternal characteristics (primarily an increase in educational level). Among blacks, adverse changes in maternal characteristics (primarily an increase in births to unmarried women) accounted for 35 percent of the increase in the rate of very low birth weight. The adverse effects of childbearing by teenagers on the outcome of pregnancy among blacks appear to have been overemphasized. The persistence of large racial differences in birth weight, even among mothers at low risk, emphasizes the need for specific targeted interventions to achieve further improvements in infant health. 相似文献

AIM: To examine factors affecting birthweight of Aboriginal infants in the Kimberley region of north-west Australia. Research design: A retrospective study of maternal and infant health records obtained through routine data collection. Subjects and methods: Birthweight and length of 2959 infants born to 1822 women from 1986 to 1994 were analysed. Mothers and infants were matched using unique identification codes. Index births and subsequent births to the same mother were collated in order to examine relative birth order effects and to calculate birth intervals. RESULTS: Regression analysis showed significant associations between weight of the index birth and maternal age (p < 0.001), remoteness of locality (p < 0.01), sex of the infant (p < 0.001) and maternal height (p < 0.001). Length at birth was significantly associated with ethnicity of infant (Aboriginal vs Aboriginal/non-Aboriginal admixture, p < 0.05), sex (p < 0.001), remoteness (p < 0.01) and maternal height (p < 0.001). Similar associations were observed for second and subsequent births. Birth interval was not associated with birthweight or length. Low birthweight was also more common to Aboriginal mothers compared with mothers of Aboriginal/non-Aboriginal admixture (13.1% vs 9.2%; chi(2) = 5.1, p < 0.025) even though there were no differences in height between these two groups. Teenage mothers (< or =19 years) were no more likely to have low birthweight babies than older mothers. Of the variables examined, the only significant predictor of low birthweight was a previous low birthweight baby (relative risk = 4.45, p < 0.001). CONCLUSIONS: Short birth intervals and teenage births were not significant contributors to low birthweight in the present study. The high prevalence and duration of breastfeeding in the Kimberley may contribute to long average birth intervals. Pre-term birth, rather than intrauterine growth retardation, is likely to be the most common cause of low birthweight in this population. 相似文献

The epidemiology and genetics of microtia-anotia (M-A) were studied using data collected from the Italian Multicentre Birth Defects Registry (IPIMC) from 1983 to 1992. Among 1,173, 794 births, we identified 172 with M-A, a rate of 1.46/10,000; 38 infants (22.1%) had anotia. Of the 172 infants, 114 (66.2%) had an isolated defect, 48 (27.9%) were multiformed infants (MMI) with M-A, and 10 (5.8%) had a well defined syndrome. The frequency of bilateral defects among non-syndromic cases was 12% compared to 50% of syndromic cases (p = 0.007). Among the MMI only holoprosencephaly was preferentially associated with M-A (four cases observed upsilon 0.7 expected, p = 0.005). No significant variations were identified in the prevalence of non-syndromic cases by geographical area (range 0.62-2.37/10,000 births) or by five month time periods (range 0.21-2.58/10,000 births), nor was there evidence of time trends. When M-A cases were compared to controls, we found that mothers with parity 1 had a higher risk of giving birth to an MMI with M-A, and that mothers with chronic maternal insulin dependent diabetes were at significantly higher risk for having a child with M-A. MMI with M-A had higher rates of prematurity, low birth weight, reduced intrauterine growth, and neonatal mortality than infants with isolated M-A and controls. Babies with isolated M-A had, on average, a lower birth weight than controls; the difference was higher for females. The analysis of pedigrees and familial cases suggests an autosomal dominant trait with variable expression and incomplete penetrance in a proportion of cases, or a multifactorial aetiology. Three cases had consanguineous parents, but the absence of M-A among previous sibs does not support autosomal recessive inheritance. 相似文献

BACKGROUND: Inhaled corticosteroids are recommended as first-line therapy for pregnant women with moderate to severe asthma, although the effects on pregnancy outcome are uncertain. A low compliance with the recommendations might lead to inadequate control of asthma, which has been associated with adverse outcomes both for the mother and the infant. OBJECTIVE: To investigate whether the reported use of inhaled budesonide (Pulmicort) during pregnancy influences birth outcome. METHODS: Data were derived from the Swedish Medical Birth Register, which includes 99% of births in Sweden. During 1995 to 1998, 293,948 newborn infants were identified. Pregnancy outcomes were compared for mothers in Sweden reporting asthma medication usage with those reporting no asthma medication usage. RESULTS: The 2,968 mothers who reported use of inhaled budesonide during early pregnancy gave birth to infants of normal gestational age, birth weight, and length, with no increased rate of stillbirths or multiple births. The rate of caesarean births was higher among mothers who used asthma medication during their pregnancy than among the control group. CONCLUSIONS: The use of inhaled budesonide in Sweden is not linked with any clinically relevant effects associated with pregnancy outcome. 相似文献

The aim of this study was to survey multiple birth data and to analyze the recent trends of multiple births and its consequences on perinatal problems in Korea from 1991 to 2008. Data were obtained from the Korean Statistical Information Service. The total number of multiple births showed increasing trends. The multiple birth rate was maintained within less than 10.0 for the decade from 1981 to 1990. However, it increased gradually to reach 27.5 in 2008. The maternal age for multiple births was higher than for total live births. The mean birth weight of the total live births was 3.23 kg; for the multiple births it was 2.40 kg in 2008. The incidence of low birth weight infants (LBWI) among total live births was 3.8% in 2000 and 4.9% in 2008. For multiple births it was 49.2% and 53.0% during the same years. The incidence of preterm births among total live births was 3.8% in 2000 and 5.5% in 2008; for the multiple births it was 38.3% and 51.5% during the same years. The incidence of multiple births and its consequences on perinatal problems (preterm, LBWI, and advanced-maternal age) have been increased steadily over the last two decades in Korea. 相似文献
