Until recently, health statistics data for Native Hawaiians and Pacific Islanders (NHPI) in the United States were almost nonexistent, due to their being historically aggregated into one homogenous group with Asian Americans. However, recent studies on U.S. NHPI highlight a multitude of obesity-related health disparities indicating the necessity of disaggregated data for NHPI and their subgroups. Among the contiguous states, Utah has the highest per capita population of Pacific Islanders (U.S. Census Bureau (2009) and Tongans are one of the primary NHPI subgroups in the state, composing 27.9% of the total NHPI population. Importantly, the majority of physical activity (PA) data, including national surveillance data have been collected using indirect methods, which have been associated with considerable sources of error. Given these limitations, objective methods have recently been used to capture PA behavior. Unfortunately, there are no currently published studies reporting objectively measured PA levels for U.S. NHPI. Thus, the purpose of this study was to objectively examine the PA patterns of Tongan adults residing in Utah. (Contains 2 tables.)
