BACKGROUND Cumulative prenatal lead exposure, as measured by maternal bone lead burden, has been associated with smaller weight of offspring at birth and 1 month of age, but no study has examined whether this effect persists into early childhood. OBJECTIVE We investigated the association of perinatal maternal bone lead, a biomarker of cumulative prenatal(More)
The principal objectives of this study are to (a) investigate the prevalence of elevated blood lead levels (EBLLs) in children of three major cities of Nigeria with different levels of industrial pollution; (b) identify the environmental, social and behavioral risk factors for the EBLLs in the children; and (c) explore the association between malaria(More)
BACKGROUND Semen quality appears to have declined over the past decades but reasons for this decline are unresolved. The concurrent increase in sedentary behaviour may be a contributing factor. The objective of this study was to evaluate the relationship of physical activity and television (TV) watching with sperm parameters in a population of young,(More)
OBJECTIVE To evaluate the association between men's body mass index (BMI), early embryo quality, and clinical outcomes in couples undergoing in vitro fertilization (IVF). DESIGN Prospective cohort study. SETTING Fertility clinic in an academic medical center. PATIENT(S) 114 couples who underwent 172 assisted reproduction cycles. INTERVENTION(S)(More)
Total hair mercury (Hg) was measured among 205 women undergoing in vitro fertilization (IVF) treatment and the association with prospectively collected IVF outcomes (229 IVF cycles) was evaluated. Hair Hg levels (median=0.62ppm, range: 0.03-5.66ppm) correlated with fish intake (r=0.59), and exceeded the recommended EPA reference of 1ppm in 33% of women.(More)
OBJECTIVE To assess the relationship between dietary antioxidant intake and semen quality in young healthy males. DESIGN Cross-sectional study. SETTING University and college campuses in the Rochester, New York, area. PATIENT(S) One hundred eighty-nine university-aged men. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Semen volume, total sperm(More)
BACKGROUND Little is known about the dietary behaviors of Mexican children with regard to frequency, amount, and quality of foods consumed at eating occasions and their impact on total daily energy intake. OBJECTIVES The objectives were to 1) describe foods consumed across eating occasions and 2) examine whether the number or type of total eating(More)
OBJECTIVE To prospectively evaluate the associations of folate with assisted reproductive technology outcomes within a population in the United States. METHODS This analysis included women (n=232) in a prospective cohort study at the Massachusetts General Hospital Fertility Center. Diet was assessed before assisted reproductive technology treatment using(More)
STUDY QUESTION Is increased consumption of dairy foods associated with lower semen quality? SUMMARY ANSWER We found that intake of full-fat dairy was inversely related to sperm motility and morphology. These associations were driven primarily by intake of cheese and were independent of overall dietary patterns. WHAT IS KNOWN ALREADY It has been(More)
OBJECTIVE To examine longitudinal associations of prenatal, infancy, and early childhood lead exposure during sensitive periods with height and body mass index (BMI). STUDY DESIGN A total of 773 participants were recruited between 1994 and 2005 in Mexico City. Lead exposure history categories were constructed for the prenatal period (maternal patellar(More)
