ABSTRACT
Native American populations have higher obesity and diabetes rates overall in the U.S. Percentages of obesity among Native American children were 11-25% higher than the national average. Among Navajo, cultural lifestyles changes have led to less physical activity and obesity problems with youth more disassociated from traditional Navajo living, culture, beliefs, language and religion. They were at highest risk for Type II diabetes among ethnic groups due to less physically activity, increased weight gain and obesity.
This study had dual purposes: Part one of this study was to examined the perceptions of physical activity, physical education and living healthy lifestyles of Navajo adolescents, physical educators, a Navajo culture teacher, a Diné studies teacher and a community member. Part two of this study examined the physical activity patterns of Navajo adolescent students. To gain their perspectives, eight Navajo students (9-12 grades), two physical educators, two classroom teachers and one community member were recruited and interviewed individually for 60-minutes. Secondly, pedometers were used to assess the students’ physical activity levels during the school day and 24-hour increments.
Results of the part one study indicated important aspects of physical activity by Navajo adolescents, physical education teachers, classroom teachers and a community member were cultural identity, family involvement, and structure of family/extended family. Navajo respondents participated in traditional form of running in the morning, a practice performed by parents and/or extended family. Physical activity was described as active involvement of the body, movement, physical fitness, and sport related interests. Stakeholders described physical activity and healthy living as culturally driven beliefs and learning based on Navajo way of life.
Findings of part two study indicated that boys were significantly more physically active on weekday than girls t(32)=2.04, p=<.05. Weekday step counts for boys indicated (M=11,078, SD= 4,399) and for girls (M=7,567, SD=5,613). Girls were significantly more active on weekend t(27)=2.30,p=.03. Weekend step counts indicated boys and girls accumulated (M=6493, SD=5650) and (M=7589, SD=5614) steps. Physical education step counts showed minimal differences between boys (M=2203, SD=918) and girls (M=1939, SD=889) step counts. Overall results indicate that Navajo adolescents did not meet daily physical activity recommendations.

Description
It is broadly accepted that physical activity provides substantial health benefits. Despite strong evidence, approximately 60% to 95% of US adults are insufficiently active to obtain these health benefits. This dissertation explored five projects that examined the measurement properties and methodology for a variety of physical activity assessment methods. Project one identified validity evidence for the new MyWellness Key accelerometer in sixteen adults. The MyWellness Key demonstrated acceptable validity evidence when compared to a criterion accelerometer during graded treadmill walking and in free-living settings. This supports the use of the MyWellness Key accelerometer to measure physical activity. Project two evaluated validity (study 1) and test-retest reliability evidence (study 2) of the Global Physical Activity Questionnaire (GPAQ) in a two part study. The GPAQ was compared to direct and indirect criterion measures including object and subjective physical activity instruments. These data provided preliminary validity and reliability evidence for the GPAQ that support its use to assess physical activity. Project three investigated the optimal h.d-1 of accelerometer wear time needed to assess daily physical activity. Using a semi-simulation approach, data from 124 participants were used to compare 10-13 h.d-1 to the criterion 14 h.d-1. This study suggested that a minimum accelerometer wear time of 13 h.d-1 is needed to provide a valid measure of daily physical activity. Project four evaluated validity and reliability evidence of a novel method (Movement and Activity in Physical Space [MAPS] score) that combines accelerometer and GPS data to assess person-environment interactions. Seventy-five healthy adults wore an accelerometer and GPS receiver for three days to provide MAPS scores. This study provided evidence for use of a MAPS score for future research and clinical use. Project five used accelerometer data from 1,000 participants from the 2005-2006 National Health and Nutrition Examination Study. A semi-simulation approach was used to assess the effect of accelerometer wear time (10-14 h.d-1) on physical activity data. These data showed wearing for 12 h.d-1 or less may underestimate time spent in various intensities of physical activity.
