The relationship of alcohol use and physical activity from an ecologic perspective

Purpose To determine the predictors of alcohol use ( AU ) and their relationship to physical activity ( PA ) among adolescents and to examine differences among groups using an ecologic model. Design and Methods Cross sectional secondary analysis of 11,432 adolescents (51% 8th and 49% 10th graders). Results Attitude, perception of risk, and academic performance were the strongest predictors of AU . PA did not moderate, but it had a positive influence on AU in 10th graders. Differences were observed among groups. Practice Implications Nurses can address individual and school factors in an effort to decrease AU and guide nurses in creating an individualized plan.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/102245/1/jspn12044.pd

Predictors of use of hearing protection among a representative sample of farmers

Farmers experience higher rates of noise-induced hearing loss (NIHL) than workers in most other industries. We developed a model of farmers' use of hearing protection, and tested it with a random sample ( n  = 532) of farmers from the upper Midwest. Barriers to using hearing protection (e.g., difficulty communicating; OR  = .44, p  < .003) were negatively related to use. Greater access/availability of hearing protectors ( OR  = 1.75, p  < .010) and male gender ( OR  = .43, p  < .019) were positively related to use. The model correctly predicted use of hearing protection for 74% of the cases. Overall, farmers demonstrated low hearing protector use, and results were similar to those from previous studies of non-farm workers. Findings from this study will be useful in designing interventions to increase farmers' hearing protector use and decrease their rates of NIHL. © 2010 Wiley Periodicals, Inc.

Preventive Behaviors as Correlates of Periodontal Health Status

Objectives: This investigation examined current practices of brushing, flossing, and periodic dental visits and their association with periodontal health status. Methods : Data were collected using face-to-face interviews and 40-minute in-home dental examinations with a probability sample of adults 18 years of age or older, having at least one tooth, and living in housing units in the Detroit tricounty area. Complete examinations were performed on 319 individuals. Results : On average, subjects reported brushing their teeth about twice a day. About one-third of the population reported flossing at least once a day. Loss of periodontal attachment was related to frequency of brushing while subjects who exhibited acceptable flossing ability had less plaque and calculus, shallower pocket depths, and less attachment loss. Subjects reporting a periodic dental visit at least once a year had less plaque, gingivitis, and calculus than subjects reporting less frequent visits. In regression analyses, brushing thoroughness, flossing ability and frequency, and dental visit frequency were predictors of lower plaque, gingivitis, and calculus scores. In turn, these scores were predictors of shallower pocket depths and less attachment loss. Conclusions : Brushing, flossing, and periodic dental visits were correlated with better periodontal health. The behaviors appeared to be indirectly related to pocket depth and attachment loss through their associations with plaque, gingivitis, and calculus levels.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65572/1/j.1752-7325.1995.tb02324.x.pd

Components of probability judgment accuracy: Individual consistency and effects of subject matter and assessment method

An experiment is reported in which subjects assigned probabilities to the outcomes of basketball games and to the truth of general-knowledge items. Three different methods were used for eliciting subjects' probability judgments. Subjects were more successful in selecting answers to the general-knowledge questions than they were in picking basketball game winners. The overall accuracy of their probability judgments for general-knowledge items was superior, too. On the other hand, subjects' judgments about general-knowledge questions were more overconfident, more poorly calibrated, and included greater scatter. One method of probability assessment gave subjects an irrelevant cue. This was found to increase confidence and overconfidence and to hurt calibration. Correlations between measures of performance on general-knowledge questions and basketball predictions showed substantial individual consistency in confidence, but only weak consistency in other components of judgment quality. Theoretical and practical implications are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26553/1/0000092.pd

Value and uncertainty as weighting factors in impression formation

An experiment was conducted to compare mathematical models describing how people combine information to form an impression of another person. Subjects rated how much they would like stimulus persons described by one or two adjectives. Subjects also reported their level of uncertainty about each evaluation. Models using the uncertainty measures to predict integration weights were no more successful than the equal weight averaging model. There was no evidence that extreme adjectives were given high weight. Information integration was best described by a model in which the more negative adjective in a pair is given more weight than the other adjective.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25807/1/0000370.pd

Predictors of Adherence to Nutrition Recommendations in People With Non- Insulin-Dependent Diabetes Mellitus

The purpose of this study was to determine how the components of psychosocial adjustment to diabetes predict adherence to nutrition recommendations based on self-reported successful completion of contingency contracts. The relationships between the components of psychosocial adjustment and adherence to nutrition recommendations were examined in a convenience sample of patients with non-insulin- dependent diabetes mellitus participating in a contingency contracting intervention with nurses. Patients completed a standardized instrument, the Diabetes Care Profile, at the time they were enrolled into this randomized clinical trial. High and low levels of adherence to nutrition recommendations were identified by a median split of the number of contingency contracts completed for adherence to nutrition recommendations. Subjects who reported higher regimen adherence and a higher support ratio (received more diabetes-specific social support than desired) were significantly less likely to engage in contingency contracting for adherence to nutrition recommendations .Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68967/2/10.1177_014572179702300206.pd

Protocol of a randomized controlled trial of sun protection interventions for operating engineers

Abstract Background Skin cancer are increasing and some types of skin cancer are among the most lethal cancers yet are easily preventable. However, sun protection interventions are rarely implemented among outdoor workers. Our prior work shows that Michigan Operating Engineers (heavy equipment operators) spend an average of 4–5 hours in the sun, about one-third reported getting sun burned at least once a summer, and over half burned more than once a summer. About three-quarters of the sample never or only sometimes used sun block. Methods/design Using the Health Belief Model as a guide, this randomized controlled trial (RCT) will test the efficacy of four sun protection interventions targeting Operating Engineers: a) education only; b) education and mailed sunscreen; c) education and text message reminders; and, d) education, mailed sunscreen, and text message reminders. Participations in the study will be offered during regularly scheduled safety trainings at the Local 324 Training Center. Pre- and post-intervention surveys will be collected to determine changes in sunscreen use and sun burning, the primary dependent variables. The analyses will include: a) paired t-tests to determine changes over time (from pre-intervention to post–intervention) in outcome variables (sunscreen use and burning) separately in the 4 intervention groups, b) Repeated Measures Analysis of Variance (RM-ANOVA) to compare the changes in outcomes across the 4 groups, and c) t-tests on change scores as follow-ups to the RM-ANOVA to determine exactly which groups differ from each other. Discussion Based on the outcome of this study, we will develop a RO1 for wider scale testing and dissemination in conjunction with the International Training Center which services North America (including the US, Mexico, and Canada). Wide scale dissemination of an efficacious sun protection intervention has the potential to substantially impact skin cancer rates among this population. The ultimate goal is for high reach, high efficacy, and low cost. Trial registration NCT01804595http://deepblue.lib.umich.edu/bitstream/2027.42/112879/1/12889_2013_Article_5170.pd

A Molecular Hydrodynamic Theory of Supercooled Liquids and Colloidal Suspensions under Shear

We extend the conventional mode-coupling theory of supercooled liquids to systems under stationary shear flow. Starting from generalized fluctuating hydrodynamics, a nonlinear equation for the intermediate scattering function is constructed. We evaluate the solution numerically for a model of a two dimensional colloidal suspension and find that the structural relaxation time decreases as $\dot{\gamma}^{-\nu}$ with an exponent $\nu \leq 1$, where $\dot{\gamma}$ is the shear rate. The results are in qualitative agreement with recent molecular dynamics simulations. We discuss the physical implications of the results.Comment: 5 pages, 1 figur
