The relationship between socioeconomic status and infant mortality in a metropolitan aggregate, 1989–1991

This paper presents the results of an ecological analysis of the relationship between infant mortality and economic status in a metropolitan aggregate comprised of seven of the larger cities in Ohio during the three years centering on the 1990 census. Using a summary income score derived for the census tract of mother's usual residence, the census tracts in the seven metropolitan centers were divided into broad income groupings and three-year average infant mortality rates were computed for each area, by age, sex, race, and selected causes of death. The most important conclusion to be drawn from the data is that in spite of some remarkable declines in overall levels of infant mortality during the past few decades, there continues to be a very clear and pronounced inverse association between income status and infant mortality. The general inverse association is observed for both sexes, for whites and nonwhites, and for all major causes of infant death. At the same time, the data reveal notable differences in the magnitude of the relationship by sex, and especially by age at death, race, and cause of death. Explanations of these differences are suggested, and a conclusion notes some of the difficulties encountered in developing programs aimed at closing the infant mortality gap between the richest and poorest segments of the society.This is an expanded version of a paper presented at the annual meetings of the Eastern Sociological Society in Baltimore, Maryland (March 17–20, 1994).

Abstract

Preparation for blizzard conditions by respondents in Wood County, Ohio, in 1977–1978 was higher than expected; a majority of those who received warnings responded with further preparation, but planned little more preparation for the winter of 1978–1979. The best predictors of preparation were: place of residence, age, marital status, sex, and occupation. Variables best predicting plans to prepare for the approaching winter were: maintenance expense incurred as a result of the winter of 1977–1978, marital status, the number of family members at home during the blizzard, and place of residence.

The respondents had a reasonably clear understanding of their actual situation; there was little evidence to suggest they were poorly prepared and unrealistic at the same time. Further examination of the theory of “bounded rationality” to determine conditions under which it is most useful is suggested.     

Trends in the relationship between socioeconomic status and infant mortality in metropolitan Ohio, 1960–1990

This paper presents the results of an ecological analysis of the relationship between infant mortality and economic status in metropolitan Ohio at four points in time centering on the censuses of 1960, 1970, 1980 and 1990. The basic unit of analysis is the census tract of mother's usual residence, with economic status being determined by the percentage of low income families living in each tract. For each period, the census tracts were aggregated into broad income groups and three-year average infant mortality rates were computed for each area, by age, sex, race and exogenous-endogenous causes of death. The most important conclusion to be drawn from the data is that in spite of some very remarkable declines in infant mortality for all socioeconomic groups since 1960, there continues to be a very clear and pronounced inverse association between income status and infant mortality. Indeed, there is some evidence to suggest that it is stronger in 1990 than it was three decades earlier. The general inverse association is observed for both sexes, for whites and nonwhites, and for all major causes of death. At the same time, the data reveal notable variations in the pattern of the relationship over time, as well as several differences between whites and nonwhites in the nature and magnitude of the relationship. Some macro-economic hypotheses are offered to explain these temporal and racial differences in the pattern of the relationship between economic status and infant mortality.This article is an expanded version of a paper presented at the annual meetings of the Southern Demographic Association in New Orleans, 21–23 October 1993.     

Perceived violence climate: A new construct and its relationship to workplace physical violence and verbal aggression,and their potential consequences

Abstract

Workplace accidents and violence are both potential sources of employee injuries that have been dealt with in entirely separate literatures. In this study we adapted the concept of safety climate from the accident/injury literature to violence in developing the concept of perceived violence climate. A scale was developed to assess perceived violence climate, including items about management attention, concern, and policies designed to keep employees safe from violence. Data were collected from a sample of 198 nurses from a US Hospital. Perceived violence climate was found to correlate significantly with both physical violence and verbal aggression experienced by the nurses, injury from violence, and perceptions of workplace danger. Furthermore, regression analyses showed that climate explained additional variance in psychological strain and perceptions of danger over experienced violence. These results have implications for interventions aimed at producing a good perceived violence climate in order to reduce the incidence of violence and aggression within an organization.     

The Effects of Contingent Caregiver Imitation of Infant Vocalizations: a Comparison of Multiple Caregivers

The present study replicated and extended the Pelaez et al. (Journal of Applied Behavior Analysis 44:33–40, 2011) study, which examined the reinforcing effects of mothers’ contingent imitation of their infants’ vocalizations. Three infants aged 7–12 months who could vocalize sounds but not words participated with two caregivers for each infant (i.e., triads). During the intervention phase, the caregivers were asked to immediately imitate all vocalizations emitted by the child for a 3-min period. During the yoked control phase, the caregivers listened to an audio recording from the preceding condition and provided vocalizations non-contingently on the infants’ responses. The procedures yielded different results across participants; one infant emitted a higher frequency of vocalizations during the contingent imitation phases over the control phases, and the other two infants showed higher rates of responding during the control phases. However, all infants emitted more imitative return vocalizations during contingent reinforcement conditions compared with the yoked control condition.     

Temporal variations in the relationship between infant mortality and economic status

Data from a metropolitan aggregate comprising three Ohio cities for the years 1959–61, 1969–71 and 1979–81 reveal some noteworthy variations over time in the nature and magnitude of the traditional inverse association between economic status and infant mortality. This brief paper describes these variations and offers an explanation for the observed temporal changes that relates the influence of medical and infant health care advances to the prevailing overall economic situation.
