Association Of Childhood Blood Lead Levels With Firearm Violence Perpetration And Victimization, Lindsay Rae Emer
Association Of Childhood Blood Lead Levels With Firearm Violence Perpetration And Victimization, Lindsay Rae Emer
Theses and Dissertations
Over 10,000 Americans are killed in firearm homicides each year, and an additional 40,000 are injured in nonfatal shootings. There is a significant public health need to identify risk factors that can be modified to prevent firearm violence. Environmental lead exposure is a demonstrated neurotoxicant which causes behavior changes that are known to be criminogenic. More recent research has demonstrated that homicides and nonfatal shootings differ by the circumstances that lead to the shootings (i.e. gang, domestic violence, arguments) and aggregating them could lead to biased results. Although studies have found a relationship between childhood lead exposure and criminal behaviors, …
Influence Of Expectations Of Aging On Older Women’S Use Of Dietary Supplements Using The Health Promotion Theory, Barbara Emily Hekel
Influence Of Expectations Of Aging On Older Women’S Use Of Dietary Supplements Using The Health Promotion Theory, Barbara Emily Hekel
Theses and Dissertations
The use of vitamins, minerals and herbal supplements by older adults is increasing and changing. There are concerns about supplement quality, safety, and vitamin D overuse. Little is known about supplement use by nursing home residents and about factors that influence older women to use supplements. The current study describes the supplement use of 247 nursing home residents and 110 independent living women 65 years or older in the Midwestern United States. A secondary analysis of 247 medication administration records describes the prevalence of vitamin, mineral, and herbal supplement use of nursing home residents. Using the health promotion theory, the …
The Impact Of Stand-Biased Desks On After-School Physical Activity Behaviors In Children, Nathan Tokarek
The Impact Of Stand-Biased Desks On After-School Physical Activity Behaviors In Children, Nathan Tokarek
Theses and Dissertations
The purpose of this study was to assess changes in after-school time spent performing sedentary behavior (SB), light intensity physical activity (LPA), and moderate to vigorous-intensity physical activity (MVPA) among elementary school children in response to the introduction of stand-biased desks in the classroom. Thirty-one 6th grade participants randomly assigned by their teacher to a traditional (CON) or stand-biased (INT) desk provided complete accelerometer data. After-school PA and SB were measured on four consecutive weekdays at baseline and 10-weeks. Wilcoxon Rank Sum Tests were used to detect significant differences (p<0.10) in changes in the proportion of after-school wear time performing SB and PA between groups. Results suggested no significant differences in changes in after-school time performing SB (p=0.770), LPA (p=0.740), or MVPA (p=0.470). Significant differences in the change in moderate PA (INT: -1.4%; CON: -0.2%, p=0.093) were detected. Stand-biased desks were not detrimental to children’s after-school PA and SB.
