Use of prenatal testing, emotional attachment to the fetus and fetal health locus of control

This study examines the relationship between maternal emotional attachment to the fetus, beliefs about fetal health locus of control, and use of prenatal testing (i.e., amniocentesis and maternal serum screening). To date, no research has directly addressed the link between these psychosocial variables and prenatal testing uptake. Ninety-one pregnant women at risk for fetal abnormalities (i.e., 35 years of age or older) participated in the study, of whom 35 had no testing, 27 had serum screening, and 29 had amniocentesis in their current pregnancy. Results of a hierarchical multiple regression partially supported the hypothesis that internal and powerful others Fetal Health Locus of Control (Labs & Wurtele, 1986) and prenatal testing status would be predictive of attachment (Prenatal Attachment Inventory; Muller, 1993) over and above the effects of gestational age, maternal age and attitude toward abortion. Fetal Health Locus of Control beliefs regarding one’s own role (FHLC-I) in determining the health of one’s fetus were found to be predictive of prenatal attachment. Results failed to support the hypothesis that the role of health professionals (FHLC-P) would be predictive of prenatal attachment. As predicted, women who had not used prenatal testing or who underwent amniocentesis tended to have stronger prenatal attachment than those who underwent serum screening only. Results supported the hypotheses that stronger attachment to the fetus would be positively correlated with both FHLC-I and FHLC-P scores. Women who had no testing were found to hold less favourable attitudes toward abortion and rate their religious as stronger than those who had amniocentesis. Emotional attachment to the fetus was stronger among women who had previous miscarriages than those who had not, but did not differ between women who had a previous abortion and those who had not

Impact of urban development on aquatic macroinvertebrates in south eastern Australia : degradation of in-stream habitats and comparison with non-urban streams

Internationally, waterways within urban areas are subject to broad-scale environmental impairment from urban land uses. In this study, we used in-stream macroinvertebrates as surrogates to measure the aquatic health of urban streams in the established suburbs of northern Sydney, in temperate south eastern Australia. We compared these with samples collected from streams flowing in adjacent naturally vegetated catchments. Macroinvertebrates were collected over a 30-month period from riffle, edge and pool rock habitats and were identified to the family level. Macroinvertebrate assemblages were assessed against the influence of imperviousness and other catchment and water quality variables. The study revealed that urban streams were significantly impaired compared with those that flowed through naturally vegetated non-urban catchments. Urban streams had consistently lower family richness, and sensitive guilds were rare or missing. We found that variation in community assemblages among the in-stream habitats (pool edges, riffles and pool rocks) were more pronounced within streams in naturally vegetated catchments than in urban waterways
