..The delay was produced by increased physical activity, reduced television viewing and changes in BMI and fat distribution. These findings may have implications for the primary prevention of breast cancer...

..Age at menarche is an important developmental milestone known to be modified by social and environmental factors. The determinants and potential change over time of age at menarche in Colombia are not well documented...

..Thus, we examined the association of second trimester intake of trans fats with risk of preeclampsia and severe preeclampsia...

..High isoflavone intake has been related to decreased fertility in animal studies, but data in humans are scarce. Thus, we examined the association of soy foods and isoflavones intake with semen quality parameters...

..Fish and seafood n-3 fatty acids may prevent or delay the progression of prostate cancer, but epidemiologic studies do not uniformly support this hypothesis...

..To examine the association between body weight and measures of male reproductive potential...

..However, most of these studies have retrospectively collected information on alcohol and caffeine intake, making the results susceptible to biases...

..27; range, -0.14 to 0.85). Correlations for nutrient intakes were consistently low (median, 0.06; range, -0.35 to 0.27). Overall, the FFQ did not validly reflect overall preschool diet when completed by mothers 4 decades later...

..However, this food frequency questionnaire did not validly measure overall adolescent diet when completed by middle-aged and older adults on average 48 years after adolescence...

..Trans-fatty acids were present in human sperm and were related inversely to sperm concentration (r = -0.44)...

..The objective of the study was to evaluate whether intake of protein from animal and vegetable origin is associated with ovulatory infertility...

..Previous studies suggest a positive association between markers of trans-fatty acid intake and prostate cancer. We therefore prospectively evaluated the association between blood trans-fatty acid levels and risk of prostate cancer...

..To evaluate whether iron supplement use or greater intake of total, heme and nonheme iron is associated with lower risk of ovulatory infertility...

..Pharmacologic activation of the peroxisome proliferator-activated receptor gamma (PPAR-gamma) improves ovulatory function in women with polycystic ovary syndrome, and specific dietary fatty acids can affect PPAR-gamma activity...

..Yet, few studies have been conducted in humans and their results are inconsistent. We evaluated whether intake of dairy foods was associated with anovulatory infertility and whether this association differed according to fat content...

..Animal models suggest that n-3 fatty acids inhibit prostate cancer proliferation, whereas n-6 fatty acids promote it, but epidemiologic studies do not uniformly support these findings...

..To examine whether use of multivitamins and intake of specific nutrients in multivitamins is associated with ovulatory infertility...

..To evaluate whether the amount or quality of carbohydrate in diet is associated with ovulatory infertility...

..To evaluate the relation of a dietary pattern and other lifestyle practices to risk of ovulatory disorder infertility...

..These results could suggest a potential impact on maturation of psychosocial stress in childhood due to exposure to a generalized atmosphere of violence and fear...

..Fish oil consumption has been associated with symptom improvement in studies of women with primary dysmenorrhea and with decreased endometriosis risk in autotransplantation animal studies...

..We examined whether common germline single nucleotide polymorphisms (SNPs) in the FASN gene affect prostate cancer (PCa) risk or PCa-specific mortality and whether these effects vary by body mass index (BMI)...

..Human studies have not shown consistent results. We examined the association between intakes of fish and n-3 fatty acids from fish and colorectal cancer risk in men enrolled in the Physicians' Health Study...
