Importance of cooking skills for balanced food choices.

A cooking skill scale was developed to measure cooking skills in a European adult population, and the relationship between cooking skills and the frequency of consumption of various food groups were examined. Moreover, it was determined which sociodemographic and psychological variables predict cooking skills. The data used in the present study are based on the first (2010) and second (2011) surveys of a yearly paper-and-pencil questionnaire (Swiss Food Panel). Data from 4436 participants (47.2% males) with a mean age of 55.5 years (SD=14.6, range 21-99) were available for analysis. The cooking skills scale was validated using a test-retest analysis, confirming that this new scale is a reliable and consistent instrument. Cooking enjoyment was the most important predictor for cooking skills, especially for men. Women had higher cooking skills in all age groups. Cooking skills correlated positively with weekly vegetable consumption, but negatively with weekly convenience food consumption frequency, even while holding the effect of health consciousness related to eating constant. In summary, cooking skills may help people to meet nutrition guidelines in their daily nutrition supply. They allow people to make healthier food choices. It is, therefore, important to teach children and teenagers how to cook and to encourage them to develop their cooking skills.

Conjoint Measurement of Base Station Siting Preferences

ABSTRACT Mobile communication has become a ubiquitous part of todays life. The ongoing growth of this technology, however, involves the construction of new mobile phone base stations in order to assure network coverage. The selection of a new base station site often results in conflicts between providers and public authorities, on the one hand, and residents on the other. The aim of the present study was to examine public preferences regarding base station sites. A random sample of 503 persons from the German speaking part of Switzerland was interviewed face-to-face in their homes. Conjoint analysis was used to evaluate participants’ preferences for various attributes of base stations (appearance, location, building, decision process). The results show that location plays the most important role in participants’ acceptance of base stations. The findings also indicate that most people would prefer a covered or camouflaged base station to a freely visible one. By means of a cluster analysis, several segments were distinguished, showing that base station siting preferences were not homogeneous. Implications for risk communication are discussed.

Fluency of Pharmaceutical Drug Names Predicts Perceived Hazardousness, Assumed Side Effects, and Willingness to Buy

The impact of pharmaceutical drug names on people’s evaluations and behavioural intentions is still uncertain. According to the representativeness heuristic, evaluations should be more positive for complex drug names; in contrast, fluency theory suggests that evaluations should be more positive for simple drug names. Results of three experimental studies showed that complex drug names were perceived as more hazardous than simple drug names and negatively influenced willingness to buy. The results are of particular importance given the fact that there is a worldwide trend to make more drugs available for self-medication.

Fear and anger: antecedents and consequences of emotional responses to mobile communication

Many people fear that exposure to mobile phone base stations leads to severe health effects. In addition to those fears, many citizens are unsatisfied or even angry about prevailing base station site-selection procedures. In the present study, it was investigated how these emotions, i.e. fear and anger, determine risk and benefit perceptions and the acceptance of mobile communication. Using structural equation modeling, we found that benefit perception and the acceptance of mobile phone base stations were primarily determined by anger. Risk perception, in contrast was influenced by both emotions. In addition, controllability and fairness emerged as important cognitive appraisals, or antecedents, of fear and anger, while certainty was not related to these emotions. In sum, our findings highlight that fear and anger have specific influences on risk, benefit, and acceptance of mobile communication. Furthermore, the study provides an in-depth understanding of the antecedents that lead to emotional responses within the context of mobile communication. Implications for risk communication will be derived.

Executive functions and the self-regulation of eating behavior: A review

In order to pursue the long-term goal of losing weight, a dieter needs to resist the urge to eat appealing, tasty foods. Beside sufficient motivation to resist these foods, dieters also need the capacity for successful self-regulation, and this capacity is strongly related to executive functions. Executive function is an umbrella term encompassing a number of interrelated higher-order cognitive processes that allow people to take goal-directed action. In this review, we outline how basic facets of executive functioning (updating, inhibiting, and shifting) contribute to the successful self-regulation of eating behavior. Moreover, we identify aspects of the self-regulation of eating behavior that are still under-researched. We conclude by outlining the implications of the extant research for intervention strategies and the design of future research studies on the role of executive functions for the self-regulation of eating behavior.

A self-determination theory approach to adults' healthy body weight motivation: A longitudinal study focussing on food choices and recreational physical activity.

This study focuses on body weight motivation based on self-determination theory. The impact of body weight motivation on longitudinal changes in food choices, recreational physical activity and body mass index was explored. A sample of adults (N = 2917, 47% men), randomly selected from the telephone book, completed a questionnaire in two consecutive years (2012, 2013), self-reporting food choices, recreational physical activity and body weight motivation. Types of body weight motivation at T1 (autonomous regulation, introjected regulation, and external regulation) were tested with regard to their predictive potential for changes in food choices, recreational physical activity and body mass index (BMI). Autonomous motivation predicted improvements in food choices and long-term adherence to vigorous recreational physical activity in both genders. Introjected motivation predicted long-term adherence to vigorous recreational physical activity only in women. External motivation predicted negative changes in food choices; however, the type of body weight motivation had no impact on BMI in overweight adults in the long term. Autonomous goal-setting regarding body weight seems to be substantial for healthy food choices and adherence to recreational physical activity.

Time for change? Food choices in the transition to cohabitation and parenthood.

OBJECTIVE We compared the dietary behaviour of three different household types and explored developmental trends in food choices following a life event. DESIGN The study is based on data from three Swiss Food Panel survey periods. A cross-sectional comparison between household types was conducted by using a one-way independent ANOVA. Repeated measures were analysed with a mixed ANCOVA to examine changes in dietary behaviour following a life event. SETTING Participants in the survey filled in a questionnaire in the years 2010, 2011 and 2012. SUBJECTS The final sample consisted of 3559 persons with a mean age of 56 years (range 22-94 years; 46 % men). Seventy-two people moved in with their partner and sixty-five people reported the birth of their first child. RESULTS Cross-sectional evidence confirmed that women living in households with a partner reported higher consumption frequencies for meat and processed meats compared with those living alone. Men living in cohabitation had a higher vegetable intake. The transitional effect of moving in with a partner, however, resulted in a higher intake of processed meats for both genders and a higher intake of pork and savoury items for men. Transition to motherhood was linked to an increase in vegetable consumption, while the transition to fatherhood did not change consumption patterns significantly. CONCLUSIONS Individuals in life-stage transitions are more likely to change their nutritional strategies and life events can be a window of opportunity for changes towards better food choices.

Crowdsourcing novel childhood predictors of adult obesity.

Effective and simple screening tools are needed to detect behaviors that are established early in life and have a significant influence on weight gain later in life. Crowdsourcing could be a novel and potentially useful tool to assess childhood predictors of adult obesity. This exploratory study examined whether crowdsourcing could generate well-documented predictors in obesity research and, moreover, whether new directions for future research could be uncovered. Participants were recruited through social media to a question-generation website, on which they answered questions and were able to pose new questions that they thought could predict obesity. During the two weeks of data collection, 532 participants (62% female; age  =  26.5±6.7; BMI  =  29.0±7.0) registered on the website and suggested a total of 56 unique questions. Nineteen of these questions correlated with body mass index (BMI) and covered several themes identified by prior research, such as parenting styles and healthy lifestyle. More importantly, participants were able to identify potential determinants that were related to a lower BMI, but have not been the subject of extensive research, such as parents packing their children’s lunch to school or talking to them about nutrition. The findings indicate that crowdsourcing can reproduce already existing hypotheses and also generate ideas that are less well documented. The crowdsourced predictors discovered in this study emphasize the importance of family interventions to fight obesity. The questions generated by participants also suggest new ways to express known predictors.

The Role of Convictions and Trust for Public Protest Potential in the Case of Carbon Dioxide Capture and Storage (CCS)

ABSTRACT For the public to accept new technologies, trust and convictions play an important role. In the present research, we used structural equation modeling to examine an extensive causal model of the role of convictions and trust for the publics protest potential against carbon dioxide capture and storage (CCS) among a large sample of the general population (N = 769). Trust, convictions, perceived benefits, and risks were included in the model. Our model fitted the data well. Convictions regarding emission reduction, decentralization of energy production, and tampering with natural structures in the deep subsurface influenced the perception of benefits and risks. Trust, in contrast, was barely influential. Perceived benefits were more prominent for public protest potential than perceived risks. However, perceived benefits did not dominate perceived risks as much as earlier studies found for acceptance. We argue that trust can become fully effective as a determinant of perceived risks and benefits only when the public perceives the distinct positioning of the stakeholders involved. Until then, laypeople are likely to draw on their own convictions and intuitive mental concepts for making decisions about accepting a new technology or protesting it.

Physical activity as a moderator of the association between emotional eating and BMI: Evidence from the Swiss Food Panel

Objective: Research has demonstrated that emotional eating (eating induced by negative affect or distress) is associated with overconsumption and weight gain. This study tests whether recreational physical activity attenuates the relationship between emotional eating and body weight. Design: Analyses are based on the second (2011) and third (2012) wave of the Swiss Food Panel, an ongoing longitudinal survey of the eating and activity behaviour of the Swiss population. Data from 3425 participants (47% males) with a mean age of 56 years (SD = 14) were analysed. Main outcome measures: Body mass index, health consciousness and food consumption (vegetables/fruits and sweet, high-fat foods). Results: Analyses revealed an independent interaction effect of emotional eating and recreational physical activity, over and above other predictors of Body Mass Index (BMI). Compared to their low-active counterparts, highly active emotional eaters had a lower BMI and consumed more vegetables and fruits. No difference was found for sweet, high-fat foods. Conclusion: The results suggest that emotional eaters who are also highly active may still feel the urge to eat when under emotional distress; however, they also choose more healthy foods to cope with this distress. Increasing physical activity could be a promising intervention strategy in preventing weight gain in emotional eaters.
