Validation Of Physical Activity Recording By Adolescent Girls, Alison Camesano
Validation Of Physical Activity Recording By Adolescent Girls, Alison Camesano
Electronic Theses and Dissertations
Physical activity is recorded in bone mineralization studies because physical activity increases bone mass and decreases the risk of osteoporosis. The purpose of this research was to validate a method of physical activity recording used in a longitudinal bone study of adolescent girls. The physical activity recording method was a combination of a diary and an interview-administered recall. The method was validated against an objective measure of physical activity. Twenty-four adolescent girls between the ages of 9.8 and 14.1 wore Stayhealthy RT3 Research Trackers (tri-axial accelerometers) arid recorded their activity for 24 hours on a diary form. The activity records …
Determination Of Residual Hexazinone In Maine's Soil And Water, L. Brian Perkins
Determination Of Residual Hexazinone In Maine's Soil And Water, L. Brian Perkins
Electronic Theses and Dissertations
Hexazinone, a systemic herbicide registered for use on wild blueberries in 1983 is credited with increasing Maine's wild blueberry crop by three-fold over a 10 year period, while also increasing overall fruit quality. Unfortunately, the high water solubility of hexazinone gives it a high leaching potential. This solubility factor is exacerbated by the sandy soils where wild blueberries are commonly propagated. In 1991 a routine screen for pesticides used in blueberry agriculture revealed traces of hexazinone in water samples from property formerly used for blueberry production. This discovery has led to the development of solid phase extraction (SPE) and direct-injection …
Complementary And Alternative Medicines: The Knowledge, Attitudes And Practices Of Dietitians In Maine, Jennifer Kristy Lawrance
Complementary And Alternative Medicines: The Knowledge, Attitudes And Practices Of Dietitians In Maine, Jennifer Kristy Lawrance
Electronic Theses and Dissertations
Consumer interest in complementary/alternative medicines (CAM) has increased substantially in the past thirty years. This is due to the growing knowledge of the link between diet and disease, as well as the cost and accessibility of health care. Despite substantial advances in the medical treatment of disease, many people seek patient-directed, nonprescription approaches to prevent and treat disease. In fact, it has been estimated that consumers spend over $ 13 billion each year on CAM. More people are taking ownership of their own health, and have thus turned to nonprescription measures for the prevention and treatment of disease. For the …
Can Cranberry Supplementation Reduce Risks For Diabetes?, Belinda K. Chambers
Can Cranberry Supplementation Reduce Risks For Diabetes?, Belinda K. Chambers
Electronic Theses and Dissertations
Diabetes affects approximately 250 million people worldwide and health care costs related to diabetes equal approximately $98 billion each year. Aldose reductase has been shown to contribute to the side effects of diabetes including kidney disease, nerve disease, and retinopathy. Cranberries contain anthocyanins and other flavonoids that have been shown in vitro to inhibit the enzyme aldose reductase and to inhibit protein glycosylation. It is believed that daily cranberry supplementation could reduce side effects of diabetes. Twenty-seven adults with type 2 diabetes were recruited for this 12 week double-blind, placebo-controlled study. Fasting blood analysis was done at weeks 0, 6, …
Adolescent Girls:Calcium Intake And Sources, Laura Agard
Adolescent Girls:Calcium Intake And Sources, Laura Agard
Electronic Theses and Dissertations
Calcium is an essential nutrient required for normal growth and development of the skeleton and teeth. Adequate calcium intake is critical during early adolescence to optimize peak bone mass and decrease the risk of osteoporosis later in life. Previous researchers, however, have concluded that adolescent girls consume insufficient calcium to meet the demands of rapid skeletal growth. National surveys conducted prior to 1997 showed that t.he major sources of calcium for adolescent girls were milk and milk products. Shortly after the new Dietary Reference Intakes (DRI's) for calcium were released in 1997, calcium fortified foods became more readily available on …
