Childhood obesity is a significant but largely modifiable health risk, disproportionately affecting socioeconomically disadvantaged, racial/ethnic minority, and rural children. Elementary school–aged children typically experience the greatest increases in excess weight gain and therefore are important targets for reducing adolescent and adult obesity while improving children’s health. Our study evaluated outcomes of a 3-year elementary school–based program for reducing obesity in American Indian and White students attending eight rural schools in the U.S. upper Midwest. Method. Researchers measured body mass indexes (BMI) and other health indicators and behaviors of 308 beginning third-grade students and then again at the end of students’ third, fourth, and fifth grades. The primary focus of this study is a mixed multilevel longitudinal model testing changes in age- and gender-adjusted BMI z scores ( zBMI). Results. There was a significant decrease in zBMI across the 3-y...

Forty-four spouses were assessed within two weeks of the patients' admission. Results showed that specific types of social support (namely, socialization, guidance, and cognitive information) and the coping strategy of wishful thinking were associated with self-reported level of anxiety. In addition, cognitive information and the coping strategies of wish ful thinking and express emotions were associated with self-reported level of anger. Directionality and possible explanations for these findings are discussed.

We assessed health status and behavioral risks in American Indians (AIs) from rural, northern plains reservation communities. Methods. AI interviewers from the communities administered the core and optional modules of the Behavioral Risk Factor Surveillance System (BRFSS) to 404 AI adults randomly selected from housing lists from four AI tribal communities located on the northern plains of the U.S. The BRFSS interview assessed several health functioning areas including medical conditions, preventive screenings, and behavioral risks. We measured health disparities by comparing the AI sample data with a northern plains statewide (North Dakota) sample and a U.S. national sample. We compared outcomes with BRFSS statewide (North Dakota) and U.S. national data from telephone-based interviews. Results. AI participants showed a significantly greater prevalence of diabetes, coronary heart disease, myocardial infarction, smoking, obesity, and heavy alcohol use than either the regio...

There is some evidence that smokers experience abstinence-induced deficits in cognitive function, which are attenuated by NRTs. Additionally it's been suggested that the degree of reversal of cognitive deficits may depend on the NRT dose and the smoker's gender. In the present placebo-controlled study we investigated effects of three doses of transdermal nicotine (7 mg, 14 mg and 21 mg) on cognitive performance of 48 male and 48 female smokers after overnight abstinence and 6h of patch application. Cognitive tasks used in the study included the Conners' CPT, emotional Stroop, mental arithmetic, and verbal recall of affective prose passages. The results showed greater probability of attentional problems in the male sample compared to females as identified by the Conners' CPT. Within gender women showed improved performance in the 7 mg and 14 mg conditions on several mea...

This study explored the use of media, specifically, anti-sugary drinks television ads, as a tool for addressing sugary drinks consumption. Ad-related discussion and social norm perceptions are important to media's effects, but to date, these two influences have not been examined separately. To better parse these effects, college students (N=109) viewed anti-sugary drinks ads either with or without the presence of a friend (a manipulation of social norm perceptions), and either discussed or did not discuss the ads after viewing them. Changes in baseline sugary drinks health knowledge, attitudes toward reducing sugary drinks consumption, and intentions to reduce sugary drinks consumption were examined at post-exposure and one-week follow-up. Consumption levels were also examined at baseline and follow-up. After viewing the ads, participants across conditions reported better sugary drinks health knowledge, more positive attitudes toward reducing sugary drinks consumption, greater intentions to reduce sugary drinks consumption, and lower sugary drinks consumption, although not all effects were maintained at follow-up. Friend presence and discussion did not have substantial effects on outcomes; however, participants that viewed the ads in the presence of a friend maintained positive attitudes toward reducing sugary drinks consumption at follow-up, while those without a friend did not. Results suggest antisugary drinks ads are a promising tool for addressing sugary drinks consumption, and that social norm perceptions likely play an important role in explaining media effects.

Eighty-six participants aged 55 years and older were randomly assigned to receive either four weekly sessions of telephone-based MI for increasing physical activity, or a healthy activity living guide (information only control). Changes from baseline weekly caloric expenditure from physical activity, self-efficacy for physical activity, and stage of change for physical activity were compared across groups at posttreatment and six months follow-up. Results indicated that MI participants had higher weekly caloric expenditures from physical activity at posttreatment, but not at six months follow-up; higher self-efficacy for physical activity at six months follow-up; and demonstrated greater stage of change progression across assessments. These findings support the use of telephone-based MI for increasing physical activity in older adults in the short-term. Future studies...

Evaluation of responses to these widely used advertisements is important to determine advertisements that are most effective and their mechanisms of action. Our study tested the hypothesis that advertisements rated highest in fear-and disgust-eliciting imagery would be rated as the most effective. Methods Our laboratory study included 144 women and men aged 18 to 33; 84% were current nonsmokers. All participants viewed 6 antismoking television advertisements that depicted the health harms of smoking; they rated their responses of fear and disgust and the effectiveness of the advertisements. We used multilevel modeling to test the effects of the following in predicting effectiveness: fear, disgust, the fear-disgust interaction, the advertisement, and the participant's sex and smoking status. Follow-up analyses examined differences in ratings of fear, disgust, and effectiveness. Results Advertisement, fear, disgust, and the fear-disgust interaction were each significant predictors of effectiveness. Smoking status and sex were not significant predictors. The 3 advertisements that elicited the highest ratings of fear and disgust were rated the most effective. Conclusion Our findings support the hypothesis that antismoking advertisements of health harms that elicit the greatest responses of fear or disgust are the most effective. When advertisements elicit high ratings of both fear and disgust, advertisements with graphic imagery are effective, whereas advertisements without graphic imagery are not.

However, a child-controlled behavioural strategy, like physical activity, to maintain target BGL may be warranted. To demonstrate, pre- and post-activity BGL were collected for 73 children aged 8- to 14-years attending a diabetes camp. Change in BGL across one session of a free-play swimming activity was analysed. Average BGL was significantly reduced from 197.18 mg/dl to 177.78 mg/dl across one 45 min session, and male gender predicted larger reductions. With safety precautions and within the context of appropriate medical management, free-play activity could be used as a strategy for maintaining target BGL.

A post-campaign survey of 391 girls and boys aged 12-17 years and including 58 American Indian youth provided information about their confirmed recall (CR) of the ads; and for recalled ads, their ratings of the ads' perceived effectiveness (PE). Results were that controlling for age and smoking risk, both American Indian and white girls and boys had the highest CR for the television ad Artery and for the radio ad ABC. Artery shows fatty deposits being squeezed from a deceased smoker's aorta, and ABC presents a former smoker speaking through his electro-larynx. Among the television ads, PE ratings were highest for the ad Artery in both boys and girls. Among the radio ads, boys rated ABC highest, whereas girls rated Joe DoBoer highest-an ad that discusses mouth lesions that developed from using smokeless tobacco. An analysis of race/ethnicity differences in PE for the ad Artery and ABC indicated American Indian and white youth considered these ads equally effective. These findings indicate certain TV and radio ads depicting graphic health harms from tobacco-especially the TV ad Artery and the radio ad ABC-are highly recalled and perceived as effective by both American Indian and white girls and boys from a rural region. Future research is needed to better understand which individual- and media-level factors increase the likelihood that anti-tobacco ads will be effective in reducing youth tobacco use.

The instruments were the McGill Pain Questionnaire, the Pain Perception Profile and Numerical Ratings. Three distinct factor models, each corresponding to a different hypothesis about how these pain measures are related, were tested using confirmatory factor analysis in a sample of 419 headache sufferers. A three-factor model, postulating three correlated factors defined by the three assessment instruments best explained the correlations between the pain measures. Measures of sensory, affective and intensity dimensions from the three instruments failed to exhibit convergent or discriminant validity. Rather, instrument variance obscured the pain qualities the three pain instruments were designed to assess. These findings suggest that greater attention needs to be paid to how formal characteristics of pain assessment instruments influence patients' descriptions of their pain.

In an effort to clarify the factor structure of the PRI, 3 different factor models were compared using confirmatory factor analysis in 2 samples of low-back pain patients (N = 1372) and in a third sample of patients suffering from other chronic pain problems (N = 423). A 4-factor model, similar to those obtained in previous studies where multiple criteria were used to determine the number of factors extracted, best explained covariation among PRI subclasses. However, relatively high inte~actor correlations (approximately two-thirds of the variance explained by the best fitting factor structure was common variance) cast doubt on the discriminant validity of PRI subscales; examination of relationships between the PRI and MMPI subscales also faiied to provide evidence of the discriminant validity or clinical utility of PRI subscales. Reducing the information from the 10 PRI sensory subclasses to a single subscale score may seriously limit the usefulness of the PRI. Alternate methods of using PRI data are suggested.

College males (N = 108) listened to these stories and completed questionnaires assessing self-reported sexual arousal and desire, their perceptions of the woman s enjoyment and sexual desire in the stories, their likelihood of acting like the man in the stories, and how likely they would be to read similar stories. Multiple regression analyses revealed that overall sexual interest variables were significant predictors of responses to both consensual and nonconsensual stories, while interest in sexual aggression predicted responses to only the nonconsensual story. The present study highlights the importance of considering overall sexual interest measures in sexual aggression research.

Prevention efforts can be improved by better understanding relationships between health behaviors and overweight and obesity. This study examined such relationships in young American Indian and white children living in the rural United States. Self-report measures of diet, screen time (passive and active), and physical activity were combined with cardiovascular fitness in cross-sectional analyses to predict weight categories based on body mass index percentiles in 306 American Indian and white children (aged 8-9 years) from a rural area in the upper Midwestern United States. Multinomial logistic regression models were statistically significant for girls (χ2 [20] = 42.73, P < .01), boys (χ2 [20] = 50.44, P < .001), American Indian (χ2 [20] = 36.67, P < .05), and white children (χ2 [20] = 55.99, P < .001). Obesity was associated with poorer cardiovascular fitness in girls (OR = 0.82), boys (OR = 0.83), American Indian (OR = 0.79), and white children (OR = 0.85), and with passive screen time in girls (OR = 1.69), boys (OR = 2.1), and white children (OR = 1.81). Overweight was associated with passive screen time (OR = 2.24) and inversely with active screen time (OR = 0.54), but only in boys. Logistic regression models were more successful at predicting obesity than overweight in all groups of participants. Poorer cardiovascular fitness showed the strongest and most consistent association with obesity, but passive screen time was also a significant and important contributor to the prediction of obesity in most prediction models. Prediction models were similar in girls, boys, American Indian, and white children.
