Maternal experiences of racism and violence as predictors of preterm birth: rationale and study design

PAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 2001
Janet Rich-Edwards
Chronic psychological stress may raise the risk of preterm delivery by raising levels of placental corticotropin-releasing hormone (CRH). Women who have been the targets of racism or personal violence may be at particularly high risk of preterm delivery. The aims of this study are to examine the extent to which: (1) maternal experiences of racism or violence in childhood, adulthood, or pregnancy are associated with the risk of preterm birth; (2) CRH levels are prospectively associated with risk of preterm birth; and (3) CRH levels are associated with past and current maternal experiences of racism or violence. We have begun to examine these questions among women enrolled in Project Viva, a Boston-based longitudinal study of 6000 pregnant women and their children. [source]

Maternal experiences of peanut avoidance during pregnancy/lactation: An in-depth qualitative study

PEDIATRIC ALLERGY AND IMMUNOLOGY, Issue 6 2005
Joanna Turke
In 1998 the Department of Health Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment issued a report to British general practitioners, which advised that pregnant mothers with a family history of atopy may wish to avoid peanuts during pregnancy/lactation. To explore the lived-in experience of mothers who avoided/did not avoid peanuts during pregnancy/lactation in the light of the information issued. A qualitative approach, using unstructured in-depth interviews to explore what it was like for mothers to have a particular experience. A purposive sample frame was designed to ensure a maximum variation of participants. Forty-two interviews were conducted: 25 participants avoided peanuts; 15 with a family history of atopy and 10 with no such history. Seventeen participants did not avoid peanuts; 10 with a family history of atopy and seven with no such history. Emergent themes included: variations in information provision, a lack of clarity in relation to information and advice about peanut avoidance, the risks entailed and the introduction of peanuts to the developing child's diet; the importance of atopy in influencing participants' decisions to avoid peanuts and the importance of individual's choice in the decision making process. There was a significant difference in family size with respect to avoidance behaviour with ,avoider' families being smaller (p = 0.007). Avoidance was more likely in single child families (71% vs. 53%) although this difference was not significant. Improvements to the experience of avoidance and/or non-avoidance were primarily focused around provision of information and advice. In particular, a need for clear, consistent factual information and advice about the real risks associated with peanut consumption during pregnancy/lactation, and to whom these risks apply. [source]

Patterns of reproduction in Malayan silvered leaf monkeys at the Bronx Zoo

AMERICAN JOURNAL OF PRIMATOLOGY, Issue 10 2009
Nichole Shelmidine
Abstract Within phylogenetic limits reproductive characteristics of a given species may vary between populations in response to ecological and social factors. For instance, in environments where high quality nutrition is readily available, the onset and speed of reproduction are often accelerated. Other influencing factors might be maternal experience or the sex of the infant. Here we present data on reproductive characteristics for the silvered leaf monkey (Trachypithecus cristatus), a medium-sized Asian colobine housed at the Wildlife Conservation Society's Bronx Zoo as a one-male group. To place the species into an appropriate phylogenetic context, we limited our comparison to other colobine species. Demographic data span 21.4 years (October 1985 to March 2007) and derive from 30 adult females (128.0 female years). Detailed behavioral data stem from a 2.2 years study (November 2002 to January 2005; 734 days, 4,225,hr). As in other Asian colobines, receptive periods were short (mean=4.3 days, n=68). This is expected for one-male groups where receptivity likely indicates, rather than conceals, ovulation. Gestation length was estimated based on a change in the pattern of sexual behavior (mean=194.6 days, n=7). It fell within the range reported for the taxon. Births occurred year round, at an early age (mean=2.9 years, n=8), at short intervals (mean=14.9 months, n=59) in combination with a short lactation (mean 12.1 months, n=9) likely due to the nearly unlimited availability of nutrition in this zoo setting. Primiparous females tended to have a longer first interbirth interval but infant survival rates were similar to multipara possibly due to the absence of predators. Maternal investment was independent of the infant's sex and birth sex ratio was even. Our results emphasize that when interpreted with caution, zoo populations yield realistic reproductive characteristics that can help fill the gap in our knowledge about colobine life history. Am. J.

Pre- and postnatal influences on preschool mental health: a large-scale cohort study

THE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 10 2008

Background:, Methodological challenges such as confounding have made the study of the early determinants of mental health morbidity problematic. This study aims to address these challenges in investigating antenatal, perinatal and postnatal risk factors for the development of mental health problems in pre-school children in a cohort of Western Australian children. Methods:, The Raine Study is a prospective cohort study of 2,868 live born children involving 2,979 pregnant women recruited at 18 weeks gestation. Children were followed up at age two and five years. The Child Behaviour Checklist (CBCL) was used to measure child mental health with clinical cut-points, including internalising (withdrawn/depressed) and externalising (aggressive/destructive) behaviours (n = 1707). Results:, Multinomial logistic regression analysis showed that the significant risk factors for behaviour problems at age two were the maternal experience of multiple stress events in pregnancy (OR = 1.20, 95% CI = 1.06, 1.37), smoking during pregnancy (OR = 1.30, 95% CI = 1.06, 1.59) and maternal ethnicity (OR = 3.34, 95% CI = 1.61, 6.96). At age five the experience of multiple stress events (OR = 1.17, 95% CI = 1.08, 1.27), cigarette smoking (OR = 1.19, 95% CI = 1.03, 1.37), male gender (OR = 1.43, 95% CI = 1.02, 2.00), breastfeeding for a shorter time (OR = .97, 95% CI = .94, .99) and multiple baby blues symptoms (OR = 1.08, 95% CI = 1.02, 1.14) were significant predictors of mental health problems. Conclusions:, Early childhood mental health is significantly affected by prenatal events in addition to the child's later environment. Interventions targeting adverse prenatal, perinatal and postnatal influences can be expected to improve mental health outcomes for children in the early years. [source]
