ObjectiveThe objective of this study was to report the construct validity and internal consistency reliability of the Food Behavior Checklist modified for children (FBC-MC), with low-income, Youth Expanded Food and Nutrition Education Program (EFNEP)-eligible children.MethodsUsing a cross-sectional research design, construct validity was assessed using confirmatory factor analysis (weighted least squares method), and internal consistency reliability for 3 subscales was assessed using Cronbach α.ResultsNinety-seven children from low-income families completed the FBC-MC. Indicator tests suggest adequate model fit (comparative fit index = 0.962; root mean square error of approximation = 0.064) and item factor loadings were significant for all subscales (P < .05). The instrument appeared to have adequate reliability for 1 subscale (fruit and vegetable consumption, α = 0.67), but not for the other 2 (milk consumption, α = 0.43; healthful eating behaviors, α = 0.56).Conclusions and ImplicationsThe FBC-MC may be a suitable instrument for evaluating dietary behaviors among Youth EFNEP-eligible children; however, more work is needed to establish internal reliability and criterion validity. 相似文献

One of the biggest obstacles identified in achieving Millennium Development Goals (MDGs) was the lack of available qualified health personal to meet the health needs of the global population. With nurses being the main workforce component in health systems, the human resource challenge for most countries is to address the reported shortage of nurses. Skill mix is one suggestion. In Australia, workforce projections indicated a shortage of 40,000 nurses by 2010. Toward the reform of the Australian health workforce, one project aimed to develop a nationally consistent framework for nursing and midwifery specialization based on knowledge and skills to generate the first national database iteration for designated specialties. A literature review looked at the way nursing specialty practices were defined in the United Kingdom, the United States of America and Canada. Three international and three national sources of criteria for specialty nursing practice were mapped against each other. The result was six criteria synthesized to define nursing practice groups as Australian nursing specialties. Each criterion was operationalized with criteria indicators to meet Australian expectations. The nurses in Australia commented on the criteria before they were finalized. An audit of national workforce databases identified nursing practice groups. The criteria were applied to identify nursing specialties and practice strands that would form a national nursing framework. This paper reports on the criteria developed to assess specialty practice at a national level in Australia. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Few, if any, published time series studies have evaluated the effects of particulate matter air exposures by combining hospital admissions with medical visit data for smaller populations. We investigated the relationship between daily particulate matter (<10 microm in aerometric diameter or PM10) exposures with admissions and medical visits (emergency room, urgent care, and family practice) for respiratory and cardiovascular disease in Pocatello and Chubbuck, Idaho (population about 60,000), from November 1994 through March 2000. Within generalized linear models, time, weather, influenza, and day-of-week effects were controlled. In single-pollutant models, respiratory disease admissions and visits increased (7.1-15.4% per 50 microg/m3 PM10) for each age group analyzed, with the highest increases in two groups, children and especially the elderly. Statistical analyses suggest that the results probably did not occur by chance. Sensitivity analyses did not provide strong evidence that the respiratory disease effect estimates were sensitive to reasonable changes in the final degrees of freedom choice for time and weather effects. No strong evidence of confounding by NO2 and SO2 was found from results of multi-pollutant models. Ozone and carbon monoxide data were not available to include multi-pollutant models, but evidence suggests that they were not a problem. Unexpectedly, evidence of an association between PM10 with cardiovascular disease was not found, possibly due to the lifestyles of the mostly Mormon study population. Successful time series analyses can be performed on smaller populations if diverse, centralized databases are available. Hospitals that offer urgent or other primary care services may be a rich source of data for researchers. Using data that potentially represented a wide-range of disease severity, the findings provide evidence that evaluating only hospital admissions or emergency room visit effects may underestimate the overall morbidity due to acute particulate matter exposures. Further work is planned to test this conclusion. 相似文献

The protective capabilities of three Leishmania recombinant proteins - histone 1 (H1) and hydrophilic acylated surface protein B1 (HASPB1) immunized singly, or together as a protein cocktail vaccine with Montanide, and the polyprotein MML immunized with MPL-SE adjuvant - were assessed in beagle dogs. Clinical examination of the dogs was carried out periodically under blinded conditions and the condition of the dogs defined as asymptomatic or symptomatic. At the end of the trial, we were able to confirm that following infection with L. infantum promastigotes, five out of eight dogs immunized with H1 Montanide, and four out of eight dogs immunized with either the combination of HASPB1 with Montanide or the combination of H1+HASPB1 with Montanidetrade mark, remained free of clinical signs, compared with two out of seven dogs immunized with the polyprotein MML and adjuvant MPL-SE, and two out of eight dogs in the control group. The results demonstrate that HASPB1 and H1 antigens in combination with Montanide were able to induce partial protection against canine leishmaniasis, even under extreme experimental challenge conditions. 相似文献

OBJECTIVES: Learning to perform physical examination of the abdomen is a challenge for medical students. Medical educators need to find engaging, effective tools to help students acquire competence and confidence in abdominal examination techniques. This study evaluates the added value of ultrasound training when Year 1 medical students learn abdominal examination. METHODS: The study used a randomised trial with a wait-list control condition. Year 1 medical students were randomised into 2 groups: those who were given immediate ultrasound training, and those for whom ultrasound training was delayed while they received standard instruction on abdominal examination. Standardised patients (SPs) used a clinical skills assessment (CSA) checklist to assess student abdominal examination competence on 2 occasions - CSA-1 and CSA-2 - separated by 8 weeks. Students also estimated SP liver size for comparison with gold-standard ultrasound measurements. Students completed skills confidence surveys. RESULTS: Proficiency in abdominal examination technique acquired from traditional instruction boosted with ultrasound training showed no advantage at CSA-1. However, at CSA-2 the delayed ultrasound training group showed significant improvement. Students uniformly underestimated SP liver sizes and the estimates were not affected by ultrasound training. Student confidence in both groups improved from baseline to CSA-1 and CSA-2. CONCLUSIONS: Ultrasound training as an adjunct to traditional means of teaching abdominal examination improves students' physical examination technique after students have acquired skills with basic examination manoeuvres. 相似文献

This study explored preschooler feeding practices and beliefs among Spanish- and English-speaking WIC participants in Texas. The Preschooler Feeding Questionnaire examined 9 dimensions of the parent-child feeding interaction among 235 caregivers. Results from ANOVA and post hoc analyses demonstrated significant differences in reported preschooler feeding practices and beliefs among Spanish-speaking Hispanics in comparison with English-speaking Hispanics and non-Hispanics. No significant differences were found between English-speaking Hispanics and non-Hispanics. Results indicated that acculturation may impact behaviors apart from ethnicity. Nutrition professionals should understand and acknowledge the cultural context of the parent-child feeding interaction when developing programs. 相似文献

The potential benefit of platelet inhibitor drugs in reducing early thrombosis of coronary arterial vein bypass grafts was assessed in dogs. There were 26 control dogs and 24 dogs treated with dipyridamole, 55 mg/day plus aspirin, 325 mg/day. The dogs in both groups were killed at 2 hours and 1, 2, 3, 7 and 14 days after operation. The grafts were perfused with flxative in vivo, harvested and examined with light microscopy. Severe alterations of the graft wall were observed in the dogs in both groups. The grafts in the control group had a high incidence rate of thrombosis, which occurred early after the operation; those in the treated group had a significantly reduced incidence of thrombosis (p = 0.025). Our study indicates that a combined regimen of dipyridamole and aspirin is effective in reducing early graft thrombosis in dogs. 相似文献
