The international physical inactivity epidemic among children has contributed to child obesity. Schools can be an effective source of physical activity opportunity. A cross-sectional sample of 1306 American children was drawn from the Panel Study of Income Dynamics - Child Development Supplement, 2007. The aim of this study was to determine the role of in-school physical activity on body mass index (BMI) percentile among middle and high school-aged children. Multinomial logistic regression was used to assess the associations between the independent variable, physical activity, and the dependent variable, BMI percentile. After adjusting for covariates, children who had no physical activity during physical education (PE) were much more likely to be obese than normal weight in comparison with those who met the US national requirements (odds ratio = 1.58, confidence interval = 1.14, 2.20). This study suggests that meeting US national guidelines for PE-related physical activity may be effective in preventing obesity. © The Author(s) 2013.

Aim: To assess the efficacy in mortality prediction of a concordance of performance-based (timed 10-foot walk; performance-oriented mobility assessment [POMA]) and self-rated (reported ability to walk across a small room with no help from people or devices; activities of daily living [ADL]) assessments of mobility for Mexican Americans aged 75 years and older. Methods: A longitudinal study of 2069 participants aged 75 years and older from the Hispanic Established Population for the Epidemiological Study of the Elderly wave5 (June 2004 to January 2006) and wave 6 (February 2007 to February 2008) was carried out. Sociodemographic variables, performance-based (timed 10-foot walk) and self-rated assessments (reported ability to walk across a small room without the help of any people or devices) of mobility, and mortality data were obtained. Results: The ADL/POMA concordance assessment showed a prevalence of the "positively concordant" group (completed the walk and reported being able to walk, ADL and POMA both positive), followed by the "pessimist," "optimist," and "negatively concordant" groups at 80.09%, 10.50%, 3.78% and 5.63%, respectively. Logistic regression analyses showed that "negatively concordant" was a critical mortality predictor (OR 4.80; 95% CI 2.59-8.90) followed by "pessimist" (OR 1.94; 95% CI 1.12-3.36) as compared with the reference group, "positively concordant." Conclusion: The ADL/POMA concordance is an effective predictor of mortality for older Mexican Americans in the Hispanic Established Population for the Epidemiological Study of the Elderly.

Obesity continues to be an increasing health problem among African-American women. A 10-week weight-loss intervention program designed to address the problem in these women. Two different interventions (spiritually based and nonspiritually based) were tested, and both utilized a pre-test, posttest design On the basis of theories of social support, it was expected that participation in the intervention would produce a significant reduction in weight. In addition, the spiritual-based weight-loss program was hypothesized to produce greater weight reduction than the standard health (non-spiritual) program. The results demonstrated that the average weight and BMI of all participants in either a spiritually-based or a nonspiritually-based program were lower at the completion of the intervention program. In addition, the average weight and BMI loss for the spiritual group was significantly greater than the average weight and BMI loss for the non-spiritual group.

Objectives To examine the effect of nativity and sex on activities of daily living (ADLs) and mobility limitations in older Mexican Americans. Design Cross-sectional. Setting Hispanic Established Population for the Epidemiological Study of the Elderly (Hispanic EPESE) (2004-05). Participants Noninstitutionalized Mexican Americans aged 75 and older (N = 2,069; 56.3% U.S. born, 43.7% Mexican born). Measurements Sociodemographic characteristics, self-reported medical conditions (arthritis, cancer, diabetes mellitus, stroke, heart attack, hip fracture), ADLs, and gross mobility function. Results The prevalence of ADL limitation was 32.9% in U.S.-born participants and 33.9% in Mexican-born participants of mobility limitation was 56.6% in U.S.-born participants and 55.6% in Mexican-born participants. Mexican-born participants tended to report less ADL limitation (odds ratio (OR) = 0.79, 95% confidence interval (CI) = 0.59-1.05)) after controlling for sociodemographic variables and medical conditions. They were also less likely to report mobility limitation (OR = 0.64, 95% CI = 0.48-0.86) after controlling for all covariates. There was a significant effect of the interaction between nativity and sex (OR = 0.42, 95% CI = 0.24-0.74) on ADL limitation, suggesting that Mexican-born men were less disabled than U.S.-born men, whereas the opposite was true for women. No significant interaction between nativity and sex was found for mobility limitation. Conclusion Mexican-born men were less disabled than their U.S.-born counterparts, and Mexican-born women were more likely to report disability than Mexican-born men. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

Information technology is generally considered an enabler of a firm's agility. A typical premise is that greater IT investment enables a firm to be more agile. However, it is not uncommon that IT can also hinder and sometimes even impede organizational agility. We propose and theorize this frequently observed but understudied IT-agility contradiction by which IT may enable or impede agility. We develop the premise that organizations need to develop superior firm-wide IT capability to successfully manage their IT resources to realize agility. We refine the conceptualization and measurement of IT capability as a latent construct reflected in its three dimensions: IT infrastructure capability, IT business spanning capability, and IT proactive stance. We also conceptualize two types of organizational agility: market capitalizing agility and operational adjustment agility. We then conduct a matched-pair field survey of business and information systems executives in 128 organizations to empirically examine the link between a firm's IT capability and agility. Business executives responded to measurement scales of the two types of agility and organizational context variables, and IS executives responded to measurement scales of IT capabilities and IS context variables. The results show a significant positive relationship between IT capability and the two types of organizational agility. We also find a significant positive joint effect of IT capability and IT spending on operational adjustment agility but not on market capitalizing agility. The findings suggest a possible resolution to the contradictory effect of IT on agility: while more IT spending does not lead to greater agility, spending it in such a way as to enhance and foster IT capabilities does. Our study provides initial empirical evidence to better understand essential IT capabilities and their relationship with organizational agility. Our findings provide a number of useful implications for research and managerial practices.
