Background: The incidence of distal forearm fracture due to minimal/moderate trauma shows a bimodal distribution for age at event, with one peak occurring during early adolescence, in both boys and girls and the other one in postmenopausal females. The aim of this study was, therefore, to document whether the relationship between bone mineral density and fracture is different in young children compared with adolescents.
Methods: A matched-pair, case-control study has been conducted to evaluate bone mineral density in 469 young children and 387 adolescents of both sexes, with/without fracture due to minimal/moderate trauma with assurance that the compared groups were equally susceptible to the outcome event.
Objective: To estimate current consumption of whole grains in college students and determine whether there would be an increase in whole-grain consumption after the students completed an interactive introductory nutrition course focusing on disease prevention.
Methods: Eighty college students, 18-24 years old, participated in the study. Grain and whole-grain consumption, whole-grain food sources, and energy intake were measured before and after the nutrition course.
Background: During last few decades, soft drink consumption has steadily increased while milk intake has decreased. Excess consumption of soft drinks and low milk intake may pose risks of several diseases such as dental caries, obesity, and osteoporosis. Although beverage consumption habits form during young adulthood, which has a strong impact on beverage choices in later life, nutrition education programs on beverages are scarce in this population.

Design: 3-day food records were collected, verified, and analyzed before and after the intervention.
Setting: A midwestern university.
Selenium-dependent glutathione peroxidase activity is increased in healthy post-menopausal women.
Biol Trace Elem Res
October 2009
Selenium helps protect against peroxidation during aging as part of the glutathione peroxidase (GPx) antioxidant system. Selenium status, however, is often low in elderly persons who have low selenium intake, live in institutions, and have certain chronic diseases. In addition, a relationship has been observed between the female reproductive hormone, estrogen, and selenium status, with blood selenium and GPx activity coinciding with fluctuations in estrogen during the menstrual cycle.

Objective: This study evaluated the long-term effects of calcium supplementation on bone accretion among females from childhood to young adulthood.
Objective: This study was designed to determine the timing and magnitude of changes in selenium status in relation to the fluctuation of 17-beta-estradiol during the menstrual cycle and the effect of different phases of the menstrual cycle on dietary selenium intake.
Methods: Plasma 17-beta-estradiol and plasma and erythrocyte selenium and glutathione peroxidase (GPx) activity were measured in fasting blood samples collected in the morning at four times over three phases of the menstrual cycle: early follicular (EF: days 1-3 menstruation), periovulatory (PO; E-1: 1 day before estrogen peak and E: during estrogen peak) and mid-luteal (ML: 7-9 days after ovulation) in healthy women (n = 14) aged 21 to 39 years and with regular menstrual cycles (26 to 30 days). The estrogen peak was confirmed by measurement of the luteinizing hormone surge.
