Summary
This paper introduces the Mater Misericordiae Mothers' Hospital‐University of Queensland Study of Pregnancy, a prospective study of 8556 pregnant women interviewed at their first clinic visit, and subsequently interviewed some days after the birth of the baby and again 6 months later. Additional data were derived from the medical record of the pregnancy and delivery. The study was designed to assess the impact of social, psychological and obstetric factors on pregnancy outcome. We present here details of the study design, sampling, response rates and demographic characteristics of the sample.
This study reports a longitudinal prospective study of the impact of an unwanted pregnancy on the mental health of the mother. Data are derived from a Brisbane, Australian sample of 8556 mothers who were enrolled at their first clinic visit (mean gestation 18 weeks) and then interviewed again some 3-5 days after the birth and when the baby was 6 months of age. Standard scales of mental health were administered on each of these occasions and mothers whose babies were unwanted were compared with the rest of the sample.The results indicate that mothers of unwanted children have somewhat higher rates of anxiety and depression than the comparison group, but that the magnitude of the mental health differences between the two groups: (a) diminishes over the period of the follow-up, (b) may be partly attributable to the prior poor mental health of women giving birth to an unplanned and unwanted baby, (c) is such that relatively few women who give birth to an unwanted baby experience mental health problems.The paper considers the implications of these results for health planners, notes the absence of contrary data and the need to acknowledge that these results may reflect situational factors which are characteristic of but not necessarily limited to Brisbane.
A prospective cohort of 8556 pregnant women attending the Mater Misericordiae Mothers' Hospital in Brisbane was examined to consider the impact of socioeconomic status on pregnancy outcome. The indicators of socio-economic status selected were family income, maternal education and paternal occupational status. Pregnancy out-comes considered were preterm delivery, low birthweight, low birthweight for gestational age, and perinatal death. Subsidiary analyses were also undertaken for Apgar scores, time to establish respiration, need for mechanical respiration and admission to intensive care. Before adjustment, the main consistent association was between the occupational status of the father and three measures of perinatal morbidity. Initial adjustment for the mother's socio-demographic background and weight/height ratio reduced the strength and statistical significance of the above associations, while further adjustment for lifestyle variations between the three status groups further reduced the above associations to marginal statistical significance. The findings suggest that observed class differences in pregnancy outcome are attributable to the mother's personal characteristics (height/weight 2 , parity) and her lifestyle.
Interactions between doctor and patient involve participants with unequal power and possibly different interests. While a number of studies have focused upon the doctor/patient relationship, few have examined the utility of the concept of power and its capacity to help us understand the outcome of these interactions. The information sought by pregnant women from their obstetricians is used to provide a case study of one conceptualization and test of the utility of the concept of power. Pregnant women and their obstetricians are found to have different perceptions of the information that should be exchanged during their interactions. Women generally fail to obtain the information they want. Lower social class patients desire more and obtain less information than their higher status counterparts.
The normal distribution of birth weight in a Queensland population has been surveyed. A method of analysis is presented which allows for the influence of a number of factors that affect birth weight.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
