This paper examines the impact of induced abortion on birth outcomes by treating abortion as an endogenous input into the production of infant health. To gauge the direct and indirect effects of abortion, three measures of infant health are considered simultaneously: the neonatal mortality rate, the percentage of low-weight births, and the percentage of preterm births. All three are race specific and all pertain to large counties in the United States in 1977. The results suggest that by preventing unwanted births, abortion enhances the survivability of newborns of a given birth weight and improves the distribution of births among high-risk groups.  相似文献

The registration of vital events in the United States has always been under the authority of State and local areas. The preparation of national birth statistics has been made possible through a co-operative working arrangement between the Federal Government and the States. This paper traces the development of registration systems in the United States from colonial days to the present period. The absence of adequate registration systems throughout the country, during the nineteenth century, led to the use of data collected in the decennial population censuses of 1850–1900 for estimating birth rates. This procedure was abandoned because of the unreliability of the results. Steps leading to the formation of the national birth-registration area in 1915, when it included ten States and the District of Columbia, and. activities resulting in its completion in 1933 are discussed.

A major portion of the paper outlines the nation-wide test of birth-registration completeness conducted in 1940 in conjunction with the decennial census of population. Important results of the test are presented, and the methodology is explained. A similar test is being carried out in 1950. Data derived will be used to focus attention on local areas requiring registration promotion. Correction factors for statistical series based on registered events will also be obtained. The final section of the paper indicates the steps States are taking to improve quality of reporting on the birth record. Changes in the content of the standard certificate of live birth since 1915 are summarized and the statistics tabulated from birth certificates detailed.  相似文献

This paper examines the impact of unemployment on social problems in the post-war United States. Working within a conceptual framework derived from sociological and economic theory, dynamic macro social indicator models are constructed for four social problems-rates of suicide, homicide, divorce and alcoholism. In general, the results do not indicate a strong and consistent relationship between the unemployment rate and these social problems. High or increasing unemployment rates tend to raise the suicide rate, but lower the alcoholism rate and have no appreciable effect on the divorce rate. High levels of unemployment lower the homicide rate, but increases in unemployment tend to raise it. For all social problems except the divorce rate, the level of economic inequality has a consistently positive influence.  相似文献

Background

The proportion of babies born by caesarean section in Australia has almost doubled over the last 25 years. Factors known to contribute to caesarean such as higher maternal age, mothers being overweight or obese, or having had a previous caesarean do not completely account for the increased rate and it is clear that other influences exist.

Aim

To identify previously unsuspected risk factors associated with caesarean using nationally-representative data from the Longitudinal Study of Australian Children.

Methods

Data were from the birth cohort, a long-term prospective study of approximately 5000 children that includes richly-detailed data regarding maternal health and exposures during pregnancy. Logistic regression was used to examine the contribution of a wide range of pregnancy, birth and social factors to caesarean.

Findings

28% of 4862 mothers were delivered by caesarean. The final adjusted analyses revealed that use of diabetes medication (OR = 3.1, 95% CI = 1.7–5.5, p < 0.001) and maternal mental health problems during pregnancy (OR = 1.3, CI = 1.1–1.6, p = 0.003) were associated with increased odds of caesarean. Young maternal age (OR = 0.6, CI = 0.5–0.7, p < 0.001), having two or more children (OR = 0.7, CI = 0.6–0.9, p < 0.001), and fathers having an unskilled occupation (OR = 0.7, CI = 0.6–1.0, p = 0.036) were associated with reduced odds of caesarean.

Conclusion

Our findings raise the prospect that the effect of additional screening and support for maternal mental health on caesarean rate should be subject of prospective study.  相似文献

Using data from the General Social Surveys,this study compares the effects of differentincome variables on financial satisfactionamong people age 65 and above in the UnitedStates. Results suggest that simply usinghousehold income as a variable without anyadjustment does not capture the real effect ofincome on financial satisfaction. Incomeequivalence scales and per-capita income arebetter income predictors of financialsatisfaction than family income. Given thefact that it is not uncommon in financialsatisfaction as well as subjective well-beingresearch to use the family income variablewithout adjustment, findings regarding theeffect of income from those studies should beinterpreted with caution.  相似文献

Training and job mobility among young workers in the United States   总被引:3,自引:0,他引:3  
Using data from the National Longitudinal Survey of Youth from 1987 to 1992, the determinants of training and the impact of training on job turnover are examined for young private sector workers in the United States. It is found that the receipt of company training is positively correlated with education, ability, and prior tenure at the job. The results provide only limited evidence that company training reduces turnover. There is substantial evidence, however, that training which is not financed by employers increases job mobility. The results imply that training plays an important role in the job search and job matching process among young workers.

This study uses nationally representative longitudinal data from the Panel Study of Income Dynamics, to examine the prevalence and predictors of extended family households among children in the United States and to explore variation by race/ethnicity and socio-economic status (SES). Findings suggest that extended family households are a common living arrangement for children, with 35?per cent of youth experiencing this family structure before age 18. Racial/ethnic and SES differences are substantial: 57?per cent of Black and 35?per cent of Hispanic children ever live in an extended family, compared with 20?per cent of White children. Further, 47?per cent of children whose parents did not finish high school spend time in an extended family, relative to 17?per cent of children whose parents earned a bachelor's degree or higher. Models of predictors show that transitions into extended families are largely a response to social and economic needs.  相似文献

A goal of publicly subsidized family planning programs in the United States is to prevent unwanted births, and the primary means being used to achieve this goal is to increase coverage with physician-administered contraception, with priority being given to persons from low-income families. We analyzed data from families living in low-income neighborhoods to determine whether that means would contribute to that goal, and if so, how much unwanted fertility might be decreased through increased coverage with physician-administered methods.The results indicate that increased coverage with those methods would decrease unwanted fertility by 80 percent (79 percent among blacks, 83 percent among whites). Increasing the ratio of sterilization to pill and IUD makes the effect of the increased coverage even more dramatic.  相似文献

A share of the recent decline in birth expectations of young American wives may be due to the historically unique stimulus of intense public attention to population growth and family size. Data on whites from numerous national surveys provide at least four types of evidence favoring this thesis: a sudden massing of responses in the two-child category (the ZPG formula); a tolerance for the large family; an aversion to childlessness and the one-child family; and an inconsistency between respondents’ evaluations of the family cycle and childspacing, on the one hand, and their personal acceptance of the two-child norm, on the other. The lack of congruence in American reproductive attitudes at present suggests that some conservatism might be wise in accepting current birth expectations as valid indicators of the long-run intentions of youthful cohorts.  相似文献

Increasing levels of obesity could compromise future gains in life expectancy in low-and high-income countries. Although excess mortality associated with obesity and, more generally, higher levels of body mass index (BMI) have been investigated in the United States, there is little research about the impact of obesity on mortality in Latin American countries, where very the rapid rate of growth of prevalence of obesity and overweight occur jointly with poor socioeconomic conditions. The aim of this article is to assess the magnitude of excess mortality due to obesity and overweight in Mexico and the United States. For this purpose, we take advantage of two comparable data sets: the Health and Retirement Study 2000 and 2004 for the United States, and the Mexican Health and Aging Study 2001 and 2003 for Mexico. We find higher excess mortality risks among obese and overweight individuals aged 60 and older in Mexico than in the United States. Yet, when analyzing excess mortality among different socioeconomic strata, we observe greater gaps by education in the United States than in Mexico. We also find that although the probability of experiencing obesity-related chronic diseases among individuals with high BMI is larger for the U. S. elderly, the relative risk of dying conditional on experiencing these diseases is higher in Mexico.  相似文献

Using data from a nationally-representative cohort of young children in the United States, we ask the following: (1) Are there race/ethnic and birth weight differentials in the likelihood of developing respiratory problems by age three in a nationally representative birth cohort? (2) To what extent does birth weight, vis-á-vis other key sociodemographic risk factors, mediate race/ethnic differentials in reported respiratory problems? (3) Does the effect of birth weight on respiratory problems risk differ by race? We find that non-Hispanic black children are 1.7 times as likely as non-Hispanic white children to be reported to have respiratory problems by age three, while the risk for Hispanic children is similar to that of non-Hispanic white children. Birth weight is also very strongly related to respiratory problem risk. Specifically, children born at very low weights (500–1499 g) have four times the odds of having respiratory problems of heavier children. Statistical controls for birth weight decrease the black-white differential by about 20%, while additional controls for sociodemographic factors reduce the race differential by an additional 35%. Finally, the net effect of birth weight is different for black and white children: whereas birth weight affects the risk of respiratory problems for black children only at low weights (<1500 g), it remains an important predictor of excess risk for white children up to 3500 g.

This article presents new estimates of age-specific overall and marital fertility rates for the entire United States for the period 1900-1910. The estimation techniques are the two-census parity increment method and the own-children method. The data sources are the 1900 census public use sample and tabulations of 1910 census fertility data published with the 1940 census. Estimates are made for the total population, whites, native-born whites, foreign-born whites, and blacks. Low age-specific marital fertility at younger ages is consistent with a view of a distinctive American fertility pattern at this time.  相似文献

Intercohort shifts between 1962 and 1972 in the occupation distributions of white and nonwhite men are analyzed and compared at ages 35-44, 45-54, and 55-64. Both white and nonwhite occupation distributions were upgraded over the decade, but among nonwhites the shifts away from the lowest-status occupations were expressed partly in increasing rates of absence from the labor force. There are indications of especially rapid shifts in the occupation distributions of nonwhite men at ages 35-44. Among whites and nonwhites intercohort shifts in the occupation distribution can be attributed primarily to changing patterns of movement from first full-time civilian jobs to current occupations, rather than to changing occupational origin distributions or patterns of movement to first jobs. The white and nonwhite occupation distributions did not show a clear pattern of convergence over the decade. They became less similar at ages 35-44 and more similar at older ages. White and nonwhite distributions were most likely to converge in those occupation groups where the share of whites was stable or declining, rather than in groups whose share of the occupation distribution was increasing. Later cohorts of nonwhites would have a much more favorable occupational distribution if they had enjoyed the mobility patterns of whites in earlier cohorts. In 1972, as in 1962, the inferior occupational chances of nonwhites are due primarily to their disadvantageous patterns of occupational mobility, rather than to impoverished social origins.  相似文献

Background

Midwifery care has been linked to positive birth outcomes. Despite the broad racial disparities in maternal and infant outcomes in the United States (US), little is known about the role of minority women in either providing or receiving this type of care. A vibrant community of minority women, who self-identify as providing these services, exists online. In this exploratory study we ask how they describe their role; view their practice; and position themselves in the broader discussions of racial health disparities in the US.

Methods

Using an internet mediated qualitative design we analyse online narratives from self-described African-American nurse-midwives, lay midwives and birth assistants; we found 28 unique websites. We collected and analysed narrative material from each site. We used a thematic analysis approach to identify recurrent and emergent themes in relation to the study question.

Results

Narratives identified a strong link to the past, as providers viewed their practice in a historical perspective linking African roots, to the diaspora, and to current African-American struggles. Providers engaged both in direct clinical work, and in activist roles. Advocacy efforts sought to expand numbers of minority birth care workers and to extend the benefits of woman-centred birth care to underserved communities.

Conclusion

Results demonstrate the continued existence and important role of diverse types of African-American birth care providers in minority communities in the US. Recognition, support, and increasing the number of midwives of colour is important in tackling racial inequalities in health. Further research should explore minority access to woman-centred care.  相似文献

Despite the rapidly growing ranks of the elderly in America, the increasing racial and ethnic diversity of this population, and the large number of seniors who are poor, there are relatively few systematic investigations that examine the causes of racial differences in health care use specifically among elders living in poverty. This article addresses this issue by examining differences in patterns of having and using a physician among the elderly poor, the role that race plays and what might explain it. We demonstrate that even within this disadvantaged and medically engaged population there are persistent and significant racial differences in having and using a doctor. Specifically, we show: (1) Whites and women are more likely to have a regular doctor than men and African Americans; (2) Among those who have a doctor, whites and women also visit the doctor with greater frequency than other groups even at the same levels of health or illness; (3) After accounting for the varying levels and effects of social connectedness, racial differences in having a doctor essentially disappear; and (4) While differences in having a regular doctor can be accounted for using measures of social connectedness, substantial and robust racial and gender differences in doctor use remain. In the end, we provide an analysis that examines typical factors known to influence health care use, and find that while need, structural factors, perceptions of care, and social connectedness have a powerful effect on doctor visits, the racial variation in using a doctor cannot be explained away with the available measures.  相似文献
