maternal fish consumption and infant birth size and gestation: new york state angler cohort study.	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 ...	2003	12826023
profiles of ortho-polychlorinated biphenyl congeners, dichlorodiphenyldichloroethylene, hexachlorobenzene, and mirex among male lake ontario sportfish consumers: the new york state angler cohort study.	great lakes sportfish consumption is a recognized human exposure source to environmental organochlorine compounds. using data collected as part of the new york state angler cohort study, 203 males were considered with regard to history of lake ontario sportfish consumption and sera levels of 57 ortho-substituted polychlorinated biphenyl (pcb) congeners, dichlorodiphenyldichloroethylene, hexachlorobenzene, and mirex. consumption of six species of highly contaminated lake ontario sportfish during ...	2005	15533334
longitudinal study of babies born to mothers enrolled in a preconception prospective pregnancy study: study design and methodology, new york state angler cohort study.	persistent environmental chemicals such as organochlorine pesticides and polychlorinated biphenyls (pcbs) have been associated with alterations in fetal development and child health including subtle differences in developmental status. previous prospective studies have ascertained prenatal or postnatal exposures but none have been designed to assess exposures at critical windows including preconception. to address this gap, we followed infants born to mothers recruited prior to conception in the ...	2005	15533332
reliability of sport fish consumption in the new york state angler cohort study.	this paper examines the reliability of sport fish consumption data from the new york state angler cohort study (nysacs). nysacs is a prospective cohort study conducted among new york state registered sportsmen and fishermen. sport fish consumption information for new york state waters including the great lakes between june 1990 and june 1991 were collected through self-administered questionnaires, spouses of male anglers were asked to provide their husbands' fish consumption during the same time ...	2005	15533330
birth defects risk associated with maternal sport fish consumption: potential effect modification by sex of offspring.	contaminated sport fish consumption may result in exposure to various reproductive and developmental toxicants, including pesticides and other suspected endocrine disruptors. we investigated the relation between maternal sport fish meals and risk of major birth defects among infants born to members of the new york state (nys) angler cohort between 1986 and 1991 (n=2237 births). birth defects (n=125 cases) were ascertained from both newborn medical records and the nys congenital malformations reg ...	2005	15533329
body burdens of polybrominated diphenyl ethers among urban anglers.	polybrominated diphenyl ethers (pbdes) have been widely used in the united states and worldwide as flame retardants. recent pbde production figures show that worldwide use has increased. to determine whether fish consumption is a source of pbde exposure for humans, a cross-sectional epidemiologic study of new york and new jersey urban anglers was conducted during the summers of 2001-2003. frequency of local fish consumption was assessed by questionnaire, and blood samples for pbde analysis were ...	2005	16330348
body burdens of mercury in lower hudson river area anglers.	the hudson river has been a federally designated superfund site for over 20 years. discharges of industrial waste and of treated and untreated sewage and atmospheric deposition have introduced mercury and other persistent pollutants to the hudson river ecosystem. despite new york and new jersey health advisories, many local anglers and their family members continue to consume fish caught from the river. to evaluate associations between body burden of mercury and local fish consumption, we conduc ...	2006	16226244
reconstruction of walleye exploitation based on angler diary records and a model of predicted catches.	the walleye population in canadarago lake, new york, was 81-95% exploited in the 1988 fishing season, the year in which a previous restriction on the length and number of legally harvestable fish was liberalized. using diary records from a subset of fishermen, growth estimates, and an estimate of the walleye population in the following year, a method is developed to reconstruct the fish population back to the spring of 1988 and thus determine the exploitation rate. the method is based on a model ...	2007	17572449
assessment of polychlorinated biphenyl congeners, thyroid stimulating hormone, and free thyroxine among new york state anglers.	experimental literature suggests that polychlorinated biphenyls (pcbs) alter thyroid function however studies of non-occupational or acute exposures in human populations have presented equivocal results. this study considered associations between pcbs and thyroid function biomarkers in a specially selected subsample of participants from the new york state angler cohort study, with the goal of hypotheses generation. between 1995 and 1997, 38 subjects donated a blood specimen and completed a quest ...	2009	19493696
exploratory assessment of perfluorinated compounds and human thyroid function.	thyroid hormones play critical roles in human neurodevelopment and adult neurocognitive function. persistent organohalogen pollutants, such as perfluorinated compounds (pfcs), may interfere with thyroid homeostasis and thus exposures to these compounds might represent risk factors for neurologic and cognitive abnormalities. in this study, serum specimens collected from thirty-one licensed anglers in new york state were analyzed for levels of thyroid stimulating hormone (tsh), free thyroxine (ft( ...	2010	19419669
joint modeling of intercourse behavior and human fecundability using structural equation models.	human fecundability is defined as the probability of conception during a menstrual cycle among couples at risk for pregnancy. it is highly relevant for understanding human reproduction and represents a series of highly interrelated and timed processes. the statistical literature has recognized the need to incorporate both biological and behavioral factors (barrett and marshall, 1969; dunson and stanford, 2005) when modeling conception probabilities, given that intercourse during the fertile wind ...	2010	20173100
