From 'trading zones' to 'buffer zones': Art and metaphor in the communication of psychiatric genetics to publics

Psychiatric genetics has a difficult relationship with the public given its unshakeable connection to eugenics. Drawing from a five-year public engagement programme that emerged from an internationally renowned psychiatric genetics centre, we propose the concept of the Buffer Zone to consider how an exchange of viewpoints between groups of people – including psychiatric geneticists and lay publics - who are often uneasy in one another’s company can be facilitated through the use of art and metaphor. The artwork at the exhibitions provided the necessary socio-cultural context for scientific endeavours, whilst also enabled public groups to be part of, and remain in, the conversation. Crucial to stress is that this mitigation was not to protect the science; it was to protect the discussion

Withstanding winter vulnerabilities: A way of life in a northern seaside community

This study responds to the dearth of qualitative research on long-term adaptation to winter climate-induced access and safety problems in rural areas in Western welfare societies. Based on qualitative interviews with 19 long-term residents in a thriving fishing village in northern Norway, the paper explores how they have adapted to and coped with roadside avalanches, blizzards, heavy snowfalls, and snowdrifts that have suddenly closed access highways and cut off other lifelines. The study shows that the inhabitants have internalised hazard adaptation and preparedness through safeguarding themselves, family members, their home and community during difficult times. Still, they admitted that local solidarity and coping capacity were changing with the arrival of newcomers who are less accustomed to and experienced with these hazards. Despite high personal and joint adaptation and coping capacities, the study also reveals denial of risk and the prevalence of worry, particularly among women. The inhabitants acknowledged mortality risk while driving on avalanche-exposed winter highways, yet assumed that they would not have a fatal accident.publishedVersio

The issue of trust and its influence on risk communication during a volcanic crisis

This paper investigates trust in the scientists, government authorities and wider risk management team during the ongoing volcanic crisis in Montserrat, WI. Identifying the most trusted communicator and how trust in information can be enhanced are considered important for improving the efficacy of volcanic risk communication. Qualitative interviews, participant observations and a quantitative survey were utilised to investigate the views and attitudes of the public, authorities and scientists. Trust was found to be dynamic, influenced by political factors made more complex by the colonial nature of Montserrat’s governance and the changing level of volcanic activity. The scientists were viewed by the authorities as a highly trusted expert source of volcanic information. Mistrust among some of the local authorities towards the scientists and British Governor was founded in the uncertainty of the volcanic situation and influenced by differences in levels of acceptable risk and suspicions about integrity (e.g. as a consequence of employment by the British Government). The public viewed friends and relatives as the most trusted source for volcanic information. High trust in this source allowed competing messages to reinforce beliefs of lower risk than were officially being described. The scientists were the second most trusted group by the public and considered significantly more competent, reliable, caring, fair and open than the authorities. The world press was the least trusted, preceded closely by the British Governor’s Office and Montserratian Government officials. These results tally well with other empirical findings suggesting that government ministers and departments are typically distrusted as sources of risk-related information. These findings have implications for risk communication on Montserrat and other volcanic crises. The importance and potential effectiveness of scientists as communicators, because of, and despite, the existence of political, cultural and institutional barriers, is exemplified by this study

Validation of anthropometry and foot-to-foot bioelectrical resistance against a three-component model to assess total body fat in children : the IDEFICS study

To compare different field methods for estimating body fat mass with a reference value derived by a three-component (3C) model in pre-school and school children across Europe. Seventy-eight preschool/school children aged 4–10 years from four different European countries. A standard measurement protocol was carried out in all children by trained field workers. A 3C model was used as the reference method. The field methods included height and weight measurement, circumferences measured at four sites, skinfold measured at two–six sites and foot-to-foot bioelectrical resistance (BIA) via TANITA scales. With the exception of height and neck circumference, all single measurements were able to explain at least 74% of the fat-mass variance in the sample. In combination, circumference models were superior to skinfold models and height–weight models. The best predictions were given by trunk models (combining skinfold and circumference measurements) that explained 91% of the observed fat-mass variance. The optimal data-driven model for our sample includes hip circumference, triceps skinfold and total body mass minus resistance index, and explains 94% of the fat-mass variance with 2.44 kg fat mass limits of agreement. In all investigated models, prediction errors were associated with fat mass, although to a lesser degree in the investigated skinfold models, arm models and the data-driven models. When studying total body fat in childhood populations, anthropometric measurements will give biased estimations as compared to gold standard measurements. Nevertheless, our study shows that when combining circumference and skinfold measurements, estimations of fat mass can be obtained with a limit of agreement of 1.91 kg in normal weight children and of 2.94 kg in overweight or obese children

Sleep duration and body-weight development during puberty in a Dutch children cohort

Background:Short sleep duration is associated with obesity during childhood and adulthood.Objective:The objective of our study was to investigate the relationship between sleep duration and body mass index (BMI) from Tanner stages 1 to 5 in a Dutch children cohort.Design:In 98 children, anthropometric measurements and leptin concentrations were measured from age 7 to 16 years; body composition, physical activity (Baecke questionnaire), hours television viewing and self-reported sleep duration were measured yearly from age 12 to 16 years. Moreover, the polymorphisms of the FTO gene (rs9939609) and parental BMI's were determined.Results:At Tanner stages 1-5 sex differences were observed in height, body weight, waist circumference, fat mass per squared meter height and leptin concentrations per kg fat mass. Inverse relationships were observed between the change in BMI (kg m(-2)) and the change in hours of sleep per night (h) from Tanner stages 1 to 4 (r=-0.68, P<0.001), from Tanner stages 2 to 5 (r=-0.35, P<0.05) and from Tanner stages 1 to 5 (r=-0.33, P<0.05). Univariate analysis of variance showed that with progressive Tanner stages, BMI increases and sleep duration decreases in an interrelated way independent of possible confounders (R (2)=0.38, P<0.02).Conclusion:Changes in BMI during puberty were inversely related to changes in sleep duration, independent of possible confounders.International Journal of Obesity advance online publication, 17 August 2010; doi:10.1038/ijo.2010.161
