This study presents an ecological analysis of the relationship between infant mortality and economic status by race in metropolitan Ohio, using census data on mother's residence and economic status determined by the percentage of low-income families living in each area. The analysis updates previous studies as white-non-white comparisons for total infant mortality are examined for the US censuses of 1960, 1970, 1980, 1990 and 2000; and more detailed period- and broad cause-specific rates are presented for 2000. A pronounced inverse association is consistently found between income status and infant mortality for whites, while for non-whites this pattern first emerges in 1979-81, disappears during the 1980s and then returns more strongly during the 1990s. Similarly, the 2000 data reveal a consistent inverse pattern between income status and infant mortality for white and non-white neonatal and postneonatal death rates, as well as exogenous cause-specific death rates. It is concluded that low-income whites and non-whites have infant mortality rates substantially higher than the overall rate for the population. Policy implications are discussed. 相似文献

Abstract This study utilizes an ecological approach based on census tracts of residence to examine the relationship between infant mortality and socioeconomic status in metropolitan Ohio at two points in time (1959–61 and 1969–71). The data presented clearly indicate that the infant mortality rate continues to exhibit a pronounced inverse association with a wide variety of socio‐economic variables. Although there were some notable exceptions and/or variations from the general patterns, a basic inverse relationship was generally found to be characteristic of both neonatal and postnatal components of infant mortality, for both males and females, and for both major exogenous and endogenous causes of death. Of all the variables examined, the one factor that emerged as the strongest and most consistent determinant of census tract variations in infant mortality was the proportion of low income families. Thus, the overriding conclusion suggested by this study is that in spite of such things as continued advances in medicine and public health, the expansion of a variety of social programs during the 1960's, and the recent resumption of a downward trend in the overall infant mortality rate, there has been little if any progress in achieving more equitable life chances for the economically deprived segments of our population. 相似文献

Empirical evidence has consistently documented the direct relationship between infant mortality and socioeconomic inequality in the United States and numerous other countries. While the majority of these studies reveal an inverse relationship between socioeconomic level and infant mortality, not even this finding is free from disagreement. Furthermore, the specific nature and magnitude of this relationship has varied over time. This study will examine the relationship between socioeconomic status and infant mortality in metropolitan Ohio by using birth and infant death data centered on the 2000 Census. The analyses presented herein will describe and analyze the relationship between infant mortality and socioeconomic status in metropolitan Ohio in the year 2000. The key finding is that in spite of remarkable declines in infant mortality during the past several decades, most notably in neonatal mortality, there continues to be a pronounced inverse association between the infant death rate and the economic status of a population. 相似文献

This paper examines whether the effects of farm background on socioeconomic differentials in fertility are diminished among nonfarm couples. The data are for a sample of white ever-married women belonging to the 1901-1910 birth cohorts. The research provides another test of the 2 generation-urbanite hypothesis 1st advanced by the Goldberg studies of Detroit and Indianapolis. Unlike a number of other studies, the findings do not support the hypothesis. Thus, a number of questions arise concerning the results obtained by previous investigators in support of this hypothesis. Different types of samples measuring farm background and socioeconomic status may be plausible explanations for the differing results. It is also important to note that both the Detroit and Indianapolis samples can hardly be considered representative of US urban populations in the 1940s and 1950s. A further difficulty with the Detroit study was that Goldberg aggregated the data of a relatively large number of cohorts. The Indianapolis sample was constrained by the eligibility requirements of the original study. The difficulties of adequately testing Goldberg's hypothesis may have been compounded by the extension of the hypothesis to nationally representative samples. Moreover, The hypothesis was not supported when education was used as a measure of socioeconomic status in the Detroit study. Until other studies can be carefully replicated, definitive answers to such questions as to whether fertility differentials by socioeconomic status will disappear or have become attenuated must remain an unanswered question. 相似文献

The incidence of child mortality in relation to the social status and fertility of Indian women was investigated on the assumptions that: 1) the higher the social status, the lower the child mortality rate; and 2) the lower the child mortality rate, the lower the family size. 311 married women in Chandigarh were grouped into 4 status categories: (1) higher educated working women (95); (2) higher educated nonworking women (75); (3) less educated nonworking women (75); and (4) less educated working women (66). The 311 women gave birth to a total of 1075 children (960 living and 115 who had died, mostly between the ages 0-5 years). Percentage of children living (89%) was different for each status category: 93% for category 1; 92% for category 2; 91% for category 3; and 81% for category 4. When analyzed by proportion of women who had lost children in each status category, the relationship between child mortality and social status confirmed the assumption that the higher the social status, the lower the mortality. In category 1, 87% had not experienced any child mortality in their family; in category 2, the figure was 77%; category 3, 72%; and category 4, 48%. The findings also confirmed the other assumption that the lower the mortality rate, the lower the fertility (Table 2). 相似文献

A number of previous studies have concluded from social area analyses of medium-size cities that there is no longer a significant correlation between socioeconomic status (SES) and infant mortality in the U.S. To determine if these findings were an artifact of too small samples, the total, neonatal, and postneonatal infant mortality rates were analyzed for 115 census tracts of San Antonio, Texas. The SES of each tract was measured by a score reflecting equally the variables of income, education, and occupation, and allowed assignment of the tracts to 1 of 4 socioeconomic rankings. All 3 infant mortality rates rose as SES decreased, with the most marked relationship being between SES and postneonatal rates. It was also found that of the 3 variables used to measure SES, income bore the strongest relationship to infant mortality. In general it should be noted that social area analysis of infant mortality is limited by the extreme reductions of sample size when additional variables are induced. 相似文献

Abstract This study examines factors impinging on the survival of children in Cameroon using longitudinal data collected by the United Nations Demographic Training and Research Institute of Yaounde, Cameroon. It deals especially with the role of socioeconomic factors (mother's education, employment, marital status, ethnicity, and household income), housing characteristics (construction materials, power source, source of water supply, extent of crowding), and immunization status on infant and child mortality. Two‐state parametric and nonparametric hazards models for the risk of death at any time within the course of the study are used, with and without accounting for unmeasured heterogeneity. Overall, overcrowding has robust deleterious effects on infant and child survival. As regards the effects of socioeconomic variables, the robustness of the effects of household income and ethnic differentials are unchanged, even after controlling for unmeasured heterogeneity; the deleterious effects of marital status are also apparent, but these effects are largely explained by unmeasured covariates. The data also suggest that the protective effects of full immunization status are robust and not contaminated by confounding factors, at least in the first 16 months of life. These findings provide solid ground to support immunization programs and efforts as a means to reduce significantly infant and child mortality. 相似文献

Abstract This paper investigates the effects of maternal demographic characteristics and social and economic statuses on infant mortality in rural Colombia. Demographic characteristics include the age of the mother, parity and length of preceding interbirth interval, and sex of infant. Measures of women's status at the time of birth include education, wage labor and occupation, economic stratum, place of residence, and whether the mother is living with a husband. The life history data for the study (involving 4,928 births) were collected in 1986 from a representative sample of two cohorts of women resident in rural central Colombia. Overall diflFerentials in infant mortality by measures of women's status are small and are in good part associated with the differing reproductive behaviors of the women and variations in breastfeeding practices. The sharp declines in infant mortality recorded in rural Colombia in recent years appear less related to improved status of women than to reductions in fertility that enhance infant survivorship and to public health interventions shared by all segments of the population. 相似文献

Nuptiality norms in rural Bangladesh favour birth during the teenage years. An appreciable proportion of teenage births are, in fact, second births. This study examines the relationship between teenage fertility and high infant mortality. It is hypothesized that if physiological immaturity is responsible, then the younger the mother, the higher would be the mortality risk, and the effect of mother's 'teenage' on mortality in infancy, particularly in the neonatal period, would be higher for the second than the first births. Vital events recorded by the longitudinal demographic surveillance system in Matlab, Bangladesh, in 1990-92 were used. Logistic regression was used to estimate the effects on early and late neonatal (0-3 days and 4-28 days respectively) and post-neonatal mortality of the following variables: mother's age at birth, parity, education and religion, sex of the child, household economic status and exposure to a health intervention programme. The younger the mother, the higher were the odds of her child dying as a neonate, and the odds were higher for second children than first children of teenage mothers. First-born children were at higher odds of dying in infancy than second births if mothers were in their twenties. Unfavourable mother's socioeconomic conditions were weakly, but significantly, associated with higher odds of dying during late neonatal and post-neonatal periods. The results suggest that physical immaturity may be of major importance in determining the relationship between teenage fertility and high neonatal mortality. 相似文献

This study used data from the 1975 World Fertility Surveys in Pakistan and Sri Lanka to examine the association between fertility and infant mortality. A positive association between the mean number of children ever born and the number of child deaths was found in both rural and urban areas of each country. In Pakistan, women with no child loss had 3.3 children ever born while those who lost 1 child had 4.7 children; in Sri Lanka the figures were 3.5 and 5.4 children, respectively. However, child replacement was much less marked when controls were introduced for demographic and socioeconomic factors. When deaths at specific parities were examined, and age and time since previous birth were controlled, child replacement at the 1st parity was reduced to .3 in Pakistan and .2 in Sri Lanka. Further control for a series of socioeconomic factors (e.g. husband's level of education, husband's occupation, household structure, religion, standard of living) reduced the child replacement ratio to .2 children in Pakistan and zero in Sri Lanka. Replacement was slightly more pronounced when there were fewer surviving male children. This analysis suggests that the relationship between infant mortality and fertility is complex. A possibility that could not be explored in this study is that variation in fertilitty may itself be responsible for some of the variation in infant mortality. 相似文献

Anthropometric indicators of nutritional status, socioeconomic factors and mortality in hospitalized children in Addis Ababa 总被引:1,自引:0,他引:1
The influence of some household and maternal variables on three anthropometric nutritional status indices of hospitalized children in Addis Ababa, Ethiopia, are examined. On admission, only 30% of these children can be classified as being of a normal overall nutritional status. There are no significant differences in weight-for-age of hospitalized children between those residing in Addis Ababa and those residing in the rural areas. Income and father's occupation appear to be the major household factors influencing the level of two of the three indices (weight-for-age and weight-for-height). Length of last closed birth interval and, to a lesser degree, maternal age appear to have significant effects on all three nutritional status indices. Upon admission to hospital, children who will in the end survive their hospital stay are on average nutritionally normal or in a mild state of malnutrition, whereas children who will die during their stay arrive in a moderate or severe state of malnutrition. The degree of malnutrition is positively related to the risk of mortality in respiratory disease patients. 相似文献

Recent investigations of infant mortality in the Southwest part of the US have shown that Spanish surname infant death rates are lower than might be expected from the relatively low socioeconomic standing of the Spanish surname population, a phenomenon that appears to be confined to the neonatal componont of the infant mortality rate. The relationship between socioeconomic status (ses) and infant mortality is examined overall and separately within the Anglo and Spanish surname populations of Corpus Christ, Texas. The investigation utilizes data from the 36 Nueces County census tracts. Most recent data on infant, neonatal, and postneonatal mortality was provided by the local health department. Subjects were limited to Anglos and those whites with at least 1 Spanish surname parent. The 1979-1983 cohort is analyzed. Information from the 1980 US census was utilized to divide the 36 census tracts into 3 SES groups: high, medium and low. The most immediately striking aspect of the findings is the significant inverse gradient in Anglos between SES and both the total infant mortality rate (IMR) and the neonatal mortality (NMR), a gradient which is nonexistent in the Spanish surname population as well as overall. In addition, Anglos and Spanish persons differ significantly with respect to all IMRs and NMRs. In the high and medium SES groups and overall, all Anglo rates are lower, while in the low SES group, Spanish surname rates are lower. These findings suggest that, among Anglos, SES is a crucial factor in infant deaths, whereas, among the Spanish surname population, having a medium or high SES does not offer any additional protection against mortality. Alternatively, lower SES does not translate into significantly lower infant mortality among Spanish persons. These findings provide support for the study's hypotheses that the SES-infant mortality association is weaker among Spanish persons than among Anglos. The analysis also shows the importance of analyzing the SES-infant mortality association separately by ethnicity. Studies in larger cities and also studies utilizing matched birth and death records are needed to further elaborate these findings. 相似文献

Abstract From data on census tract groupings from Corpus Christi, Texas, for 1979–83, this study shows that, unlike the inverse infant‐mortality‐socioeconomic‐status association observed for Anglos, no such association exists for the Spanish surname population. This finding is discussed in terms of recent research suggesting that the Spanish surname population of the Southwest has lower infant death rates than expected from its generally lower socioeconomic status. 相似文献
