Background:In 2002, the National Physical Activity and Weight Loss Survey asked two sets of questions on occupational physical activity—one question from the Behavioral Risk Factor Surveillance System (BRFSS) and eight detailed questions from the occupational physical activity questionnaire (OPAQ). This study compares the responses.Methods:On the basis of percentage of occupational physical activity reported on OPAQ, 5847 respondents were classified by three levels (sitting or standing, walking, and heavy labor). Kappa, MET-min per day, and median hours worked at the three levels were calculated to compare the two sets of questions.Results:Levels of occupational physical activity reported on the BRFSS question agreed with OPAQ (kappa = 0.56). Hours of heavy labor per day reported on OPAQ increased among the three activity levels on BRFSS.Conclusions:The BRFSS question and OPAQ classify respondents similarly by occupational physical activity. The BRFSS question is useful for overview and OPAQ, for more detailed analyses.

Background:In 2001, the Behavioral Risk Factor Surveillance System (BRFSS) included a new occupational physical activity (PA) question. This article evaluates the reliability of this survey question.Methods:Forty-six subjects were followed for 3 wk, answered 3 PA surveys by telephone, and completed daily PA logs for 1 wk. Kappa statistics determined the reliability of occupational activities (sitting/standing, walking, and heavy lifting). A descriptive analysis compared the time in specific occupational activities.Results:Eighty percent of the respondents reported “mostly sitting or standing” at work; and test–retest reliability was moderate (k = 0.40 to 0.45). The occupationally inactive sat/stood for 85% (mean hours = 5.6) of the workday, whereas the occupationally active sat/stood for 53% (mean hours = 3.9) of the workday.Conclusions:The BRFSS occupational activity question has moderate reliability, distinguishes between occupationally active and inactive persons, and can be used in surveillance systems to estimate adult occupational PA.

Less than 40% of the U.S. population achieves the recommended amount of leisure-time physical activity (LTPA) recommended by the American College of Sports Medicine [ACSM (>150 minutes/week of moderate-intensity or equivalent vigorous-intensity LTPA)]. The number of Hispanic/Latino men and women who report being physically inactive is disproportionately higher than non-Hispanic/Latinos. The purpose of this investigation is to evaluate factors which influence the achievement of meeting ACSM recommendations for LTPA among adults with Hispanic/Latino ethnicity and whites (non-Hispanic/Latino) in the southern United States. Self-reported data collected as part of the Behavioral Risk Factor Surveillance System (BRFSS) was analyzed in male and female Hispanic/Latinos and non-Hispanic/Latino whites using the Andersen Model and Chi Square Analysis to examine the association between variables. Hispanic/Latino men/women were significantly less likely to meet the ACSM recommendations (> 150 minutes/week) compared to non-Hispanic/Latinos. Lower amounts of income, education, and access to health care were all significant factors of whether Hispanic/Latinos in the Deep South achieved the ACSM recommendations for LTPA. Although the percentage of overweight Hispanic/Latinos was considerably higher than White (non-Hispanic/Latino), reported obesity was highest among Whites (non-Hispanic/Latino). LTPA between the two groups differed significantly, suggesting that not achieving the physical activity recommendations is associated with being overweight, but other factors may also contribute to being overweight and obesity.Key words. physical activity, Hispanics, leisure, obesity, overweight, disease.Resumen. Menos del 40% de la población de los Estados Unidos cumple con la cantidad de actividad física de tiempo libre (AFTL) recomendada por el Colegio Americano de Medicina Deportiva [ACSM (> 150 minutos/semana de AFTL de intensidad moderada o su equivalente de intensidad vigorosa)]. La cantidad de hombres y mujeres hispanos o latinos que reportan ser físicamente inactivos es desproporcionadamente mayor que quienes no lo son. El propósito de esta investigación es evaluar los factores que pueden influir en alcanzar las recomendaciones del ACSM para AFTL en adultos de origen étnico hispano o latino y en caucásicos (que no son hispanos o latinos) en la región Sur de los Estados Unidos. Se recolectaron datos de cuestionarios autoadministrados que son parte del Sistema de Vigilancia de Factores de Riesgo del Comportamiento (Behavioral Risk Factor Surveillance System, BRFSS), los cuales se analizaron en hombres y mujeres hispanos o latinos y en caucásicos que no lo eran, por medio del Modelo de Andersen y pruebas de Chi cuadrado para examinar la asociación entre variables. Se encontró que los hombres y las mujeres latinos tenían una menor probabilidad de cumplir con las recomendaciones del ACSM (> 150 minutos/semana) en comparación con quienes no eran hispanos o latinos. Menores ingresos económicos, educación y acceso a los servicios de salud fueron factores significativos que condicionaban si los hispanos o latinos en el extremo Sur lograban las recomendaciones del ACSM para AFTL. Aunque el porcentaje de hispanos o latinos con sobrepeso fue considerablemente mayor que los caucásicos (no hispanos o latinos), la obesidad reportada fue mayor entre los caucásicos (no hispanos o latinos). La AFTL entre los dos grupos fue estadísticamente diferente, lo cual sugiere que no alcanzar las recomendaciones de actividad física se asocia con tener sobrepeso; sin embargo, otros factores también pueden contribuir en tener sobrepeso y obesidad.Palabras claves. actividad física, hispanos, ocio, obesidad, sobrepeso, enfermedad.

Background: Few Americans accumulate enough physical activity (PA) to realize its benefits. Understanding how and why individuals use their discretionary time for different forms of PA could help identify and rectify issues that drive individuals away from certain physical activities, and leverage successful strategies to increase participation in others. Methods: The authors analyzed approximately 30 years of changes in PA behavior by intensity, type, and mode, using data from the Behavioral Risk Factor Surveillance System. Results: Since 1988, the proportions of adults most frequently engaging in exercise, sport, or lifestyle physical activity have changed noticeably. The most apparent changes from 1988 to 2017 were the proportions most frequently engaging in Exercise and Sport. In addition, the proportion of time reportedly spent in vigorous-intensity PA decreased over time, particularly among male respondents. Moreover, the proportion of Americans reporting an “Other” PA mode increased substantially, suggesting a growing need for a greater variety of easily accessible options for adult PA. Conclusions: Over time, a smaller proportion of American adults reported participating in sport and exercise modalities and reported engaging more frequently in low-intensity physical activities.
