Identifying well-connected opinion leaders for informal health promotion: the example of the ASSIST smoking prevention program

Methods used to select opinion leaders for informal behavior change interventions vary, affecting the role they adopt and the outcomes of interventions. The development of successful identification methods requires evidence that these methods achieve their aims. This study explored whether the “whole community” nomination process used in the ASSIST smoking prevention program successfully identified “peer supporters” who were well placed within their school social networks to diffuse an antismoking message to their peers. Data were collected in the United Kingdom during A Stop Smoking in Schools Trial. Behavioral data were provided at baseline and post intervention by all students. Social network data were provided post intervention by students in four control and six intervention schools. Centrality measures calculated using UCINET demonstrate that the ASSIST nomination process successfully identified peer supporters who were more socially connected than others in their year and who had social connections across the entire year group including the program’s target group. The results indicate that three simple questions can identify individuals who are held in high esteem by their year group and who also have the interpersonal networks required of opinion leaders to successfully disseminate smoke-free messages through their social networks. This approach could be used in other informal health promotion initiatives

A Novel Exercise Device for Users in Wheelchairs: A Study of Abdominal Muscle Activation

This study evaluates the use of a wheelchair balance board. The balance board was created as a sensory stimulation tool for users with various disabilities. It was originally designed to create vestibular stimulation for the person after they were loaded on. This study was used as a way to test if the balance board could be used for other things such as physical therapy and exercise. Ten able-bodied individuals were used to show the functionality of the device. They were asked to perform six different abdominal exercises while the muscle activity of their rectus abdominis and external obliques was measured using EMG electrodes. The exercises performed included: abdominal crunch, reverse crunch, full vertical crunch, torso twist, seated crunch, and sitting abdominal bend down. The last three exercises were performed on both stable ground and on the wheelchair balance board. This study found that the balance board did not cause any negative effects in terms of the abdominal muscle activation. In some cases it actually increased the muscle activation compared to the stable and floor exercises. There were no cases where the balance board caused a decrease in the amount of muscle activation in comparison to the floor exercises. The highest values for any muscle group activated in the entire study was found to be on the balance board during the sitting abdominal bend down. This demonstrates that the balance board shows promise as a tool for stimulating muscles not traditionally activated for people in a wheelchair

A comparative fMRI meta-analysis of altruistic and strategic decisions to give

The decision to share resources is fundamental for cohesive societies. Humans can be motivated to give for many reasons. Some generosity incurs a definite cost, with no extrinsic reward to the act, but instead provides intrinsic satisfaction (labelled here as 'altruistic' giving). Other giving behaviours are done with the prospect of improving one's own situation via reciprocity, reputation, or public good (labelled here as 'strategic' giving). These contexts differ in the source, certainty, and timing of rewards as well as the inferences made about others' mental states. We executed a combined statistical map and coordinate-based fMRI meta-analysis of decisions to give (36 studies, 1150 participants). Methods included a novel approach for accommodating variable signal dropout between studies in meta-analysis. Results reveal consistent, cross-paradigm neural correlates of each decision type, commonalities, and informative differences. Relative to being selfish, altruistic and strategic giving activate overlapping reward networks. However, strategic decisions showed greater activity in striatal regions than altruistic choices. Altruistic giving, more than strategic, activated subgenual anterior cingulate cortex (sgACC). Ventromedial prefrontal cortex (vmPFC) is consistently involved during generous decisions and processing across a posterior to anterior axis differentiates the altruistic/strategic context. Posterior vmPFC was preferentially recruited during altruistic decisions. Regions of the 'social brain' showed distinct patterns of activity between choice types, reflecting the different use of theory of mind in the two contexts. We provide the consistent neural correlates of decisions to give, and show that many will depend on the source of incentives

Mediators of the relationship between maternal education and children\u27s TV viewing

Background: Maternal education is consistently found to be inversely related to children&rsquo;s television viewing and is associated with aspects of the family television environment. This study investigates whether family television environment mediates the relationship between maternal education and children&rsquo;s television viewing.Methods: Parents of 1484 children reported maternal education, time their child spends watching television, and 21 aspects of the family television environment (potential mediators) during 2002 and 2003. Separate regression analyses were conducted in 2006 for each potential mediator that met two initial conditions for mediation (associated with both maternal education and children&rsquo;s television viewing (p&lt;0.10)), to assess whether inclusion reduced the association between maternal education and children&rsquo;s television viewing. Multivariable regression assessed the combined impact of all mediators.Results: Twelve of 21 potential mediators met the initial conditions for mediation. Inclusion of each resulted in decreased &beta; values (3.2% to 15.2%) for the association between maternal education and television viewing. Number and placement of televisions in the home appeared to have the greatest mediating effect, followed by frequency of eating dinner in front of the television with the child and rules about television viewing during mealtimes. Together, the 12 mediators accounted for more than one-third of the association between maternal education and children&rsquo;s television viewing time.Conclusions: This study suggests the strong inverse relationship between maternal education and children&rsquo;s television viewing is partly mediated by aspects of the family television environment.<br /

Are parental concerns for child TV viewing associated with child TV viewing and the home sedentary environment?

BackgroundTime spent watching television affects multiple aspects of child and adolescent health. Although a diverse range of factors have been found to be associated with young people\u27s television viewing, parents and the home environment are particularly influential. However, little is known about whether parents, particularly those who are concerned about their child\u27s television viewing habits, translate their concern into action by providing supportive home environments (e.g. rules restricting screen-time behaviours, limited access to screen-based media). The aim of this study was to examine associations between parental concerns for child television viewing and child television viewing and the home sedentary environment.MethodsParents of children aged 5-6 years (\u27younger\u27 children, n = 430) and 10-12 years (\u27older children\u27, n = 640) reported usual duration of their child\u27s television (TV) viewing, their concerns regarding the amount of time their child spends watching TV, and on aspects of the home environment. Regression analyses examined associations between parental concern and child TV viewing, and between parental concern and aspects of the home environment. Analyses were stratified by age group.ResultsChildren of concerned parents watched more TV than those whose parents were not concerned (B = 9.63, 95% CI = 1.58-17.68, p = 0.02 and B = 15.82, 95% CI = 8.85-22.80, p &lt; 0.01, for younger and older children respectively). Parental concern was positively associated with younger children eating dinner in front of the television, and with parental restriction of sedentary behaviours and offering sedentary activities (i.e. TV viewing or computer use) as a reward for good behaviour among older and young children. Furthermore, parents of older children who were concerned had fewer televisions in the home and a lower count of sedentary equipment in the home.ConclusionsChildren of concerned parents watched more TV than those whose parents who were not concerned. Parents appear to recognise excessive television viewing in their children and these parents appear to engage in conflicting parental approaches despite these concerns. Interventions targeting concerned parents may be an innovative way of reaching children most in need of strategies to reduce their television viewing and harnessing this parental concern may offer considerable opportunity to change the family and home environment.<br /

The relationship between water, health and global environmental change, as interpreted through five key Multilateral Environmental Agreements (MEAs)

For five Multilateral Environmental Agreements (MEAs), we have examined the way the relationship between water, health and global environmental change is expressed and how it has evolved recently. We recognize a distinction between an emphasis on water and reservoirs of water for health (for drinking water supplies, sanitation and hygiene), and a focus on places of water, where wetland ecosystems provide a service for human well-being which encompasses health. We also recognize a trend over time for the MEAs to increasingly address water, health and global change issues as a reaction to emerging infectious diseases and global pandemics. For both observations we note an increasing reliance on collaborative efforts across the MEAs, and beyond to involve international food, agriculture, trade and health sectors, and the emergent theme on ecosystem approaches to human health
