    BACKGROUND: The scientific literature poses a perplexing dilemma for pregnant women with respect to the consumption of fish from natural bodies of water. On one hand, fish is a good source of protein, low in fat and a rich source of other nutrients all of which have presumably beneficial effects on developing embryos and fetuses. On the other hand, consumption of fish contaminated with environmental toxicants such as polychlorinated biphenyls (PCBs) has been associated with decrements in gestation and birth size. METHODS: 2,716 infants born between 1986–1991 to participants of the New York State Angler Cohort Study were studied with respect to duration of maternal consumption of contaminated fish from Lake Ontario and its tributaries and gestation and birth size. Hospital delivery records (maternal and newborn) were obtained for 92% of infants for the ascertainment of gestation (weeks), birth size (weight, length, chest, and head circumference) and other known determinants of fetal growth (i.e., maternal parity, history of placental infarction, uterine bleeding, pregnancy loss or cigarette smoking and infant's race, sex and presence of birth defect). Duration of maternal fish consumption prior to the index infant's birth was categorized as: none; 1–2, 3–7, 8+ years, while birth weight (in grams), birth length (in centimeters), and head and chest circumference (in centimeters) were left as continuous variables in multiple linear regression models. Birth size percentiles, ponderal indices and head to chest circumference ratios were computed to further assess proportionality and birth size in relation to gestational age. RESULTS: Analysis of variance failed to identify significant mean differences in gestation or any measure of birth size in relation to duration of maternal lifetime fish consumption. Multiple linear regressions identified gestational age, male sex, number of daily cigarettes, parity and placental infarction, as significant determinants of birth size. CONCLUSIONS: The results support the absence of an adverse relation between Lake Ontario fish consumption and reduced birth size as measured by weight, length and head circumference. Biological determinants and maternal cigarette smoking during pregnancy remain important determinants of birth size

    A critical analysis of the efficacy of law as a tool to achieve gender equality and to address the problem of domestic violence : The case of Trinidad and Tobago

    Law is often perceived as an instrument that can effect social change. National law in Trinidad and Tobago, prima facie providing for gender equality, does not fully contemplate issues of particular concern to women, such as domestic violence. Gender equality and domestic violence are unwitting partners as women cannot achieve the former without first addressing the latter. Additionally, problems such as male dominance in politico-legal structures and lack of political will create practical obstacles to the realisation of gender equality and/or the full potential of the law. A case study of Trinidad and Tobago shows that the achievement of legal advances for women is particularly difficult where practical measures are not implemented domestically. Honouring international commitments subsequently becomes problematic as they do not guarantee change nationally and they, too, are sidelined. Gender equality and domestic violence are not given priority domestically and laws aimed towards protecting women and women’s rights are ineffective, scant and/or not enforced. The only way to achieve gender equality is through a multilevel approach from above (the UN) and, perhaps, more importantly, from below, as women have the potential to effect real national and international legal and institutional change to ensure gender equality at both levels.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
