'Meet the blockers' : jongeren, jongvolwassenen en automatische reclamevermijding online

Ad blocking – the use of browser extensions such as Adblock (Plus) or Ublock – is becoming mainstream, particularly amongst young web users. This automated form of advertising avoidance has attracted significant attention due to the loss of advertising revenues. Insights in this type of ad avoidance behavior are indispensable. By applying the theory of planned behavior (TPB), the first aim of this study is to determine the predictive value of personal attitudes, subjective norm (SN) and perceived behavioral control (PBC) in explaining behavioral intention. The second aim is to reveal the relative importance of the beliefs underpinning these three TPB components. An online survey involving 400 person’s aged between 16 and 30 years was conducted. Analysis reveals that attitude is the most important predictor to explain differences in intention to use ad blockers, followed by a person’s perceived behavior control towards ad blocking. Within attitude, the most important beliefs affecting one’s intention to use an ad blocker are less privacy concerns, less disruption and less data usage and costs.Een steekproef bij 400 Vlaamse jongere personen van 16 tot 30 jaar toont aan dat de attitude tegenover ad blockers de meest belangrijke voorspeller vormt om verschillen te verklaren in de intentie om ad blockers te gebruiken. Minder bezorgdheden omtrent privacy, minder storing en minder data en kosten vormen de meest belangrijke gedragsopvattingen

Development and validation of a short nutrition literacy scale for young adults

BackgroundDue to their high media use, young adults are frequently exposed to contradictory or even erroneous nutrition information. To properly handle and critically assess nutrition information, young adults (both general population and patient populations) need adequate levels of nutrition literacy. Currently there is a lack of suitable instruments to measure nutrition literacy in young adults (18–25 years). Therefore the aim of this study was to develop and validate a Short Nutrition Literacy (S-NutLit) scale for use in this age group.MethodsDevelopment and validation of the S-NutLit consisted of six phases: (1) item generation based on literature, (2) expert assessments to evaluate content validity, (3) cognitive interviews with the target population to assess face validity and readability, (4) pre-test to reduce the number of items, (5) validation survey to assess dimensionality with exploratory factor analyses, internal reliability with Cronbach alpha, construct and criterion validity by examining associations with age, gender, education level, health literacy, general literacy, dietary behaviors and physical activity with correlations, ANOVAs, and t-tests, (6) two-week follow-up survey to assess test–retest reliability with intra-class correlations.ResultsStarting from an initial pool of 53 items, expert assessments and cognitive interviews led to the reformulation, removal, and construction of items. Young adults aged 18–25 years participated in cognitive interviews (n = 12), pre-test (n = 101), validation survey (n = 300), and reliability survey (n = 92). The final S-NutLit consisted of 11 items rated on a 5-point scale distributed across two subscales (i.e., information skills and expert skills). Cronbach alpha values ranged from 0.79 to 0.83 and intraclass correlations from 0.61–0.79 (p < 0.001). Significant associations were observed with health literacy (r = 0.27, p < 0.001), general literacy and numeracy (rs = 0.12, p = 0.046), and education level (rs = 0.13, p = 0.025).ConclusionFindings indicate that the S-NutLit is a valid and reliable tool to assess nutrition literacy among young adults. The S-NutLit fills a gap in the field by offering a short measure of nutrition literacy and may be incorporated in digital technology to support the nutrition care process

Ninety minutes to reduce one's intention to eat meat : a preliminary experimental investigation on the effect of watching the Cowspiracy documentary on intention to reduce meat consumption

Whereas, past research has shown that using environmental arguments to reduce meat intake are unsuccessful in awareness campaigns, popular documentaries might have the potential to successfully change the public awareness of the environmental implications of meat consumption today. This preliminary study aimed to provide first empirical evidence of the potential effects of watching a popular documentary on a less-known environmental topic among a population that are habitual performers of the behavior under discussion. More precisely, the effects of watching “Cowspiracy: The Sustainability Secret” on the awareness of the environmental implications of meat consumption, the attitude toward eating less meat, and the intention to eat less meat in young adults who consume meat on an (almost) daily basis was studied. The potential impact of Cowspiracy was investigated from the Integrated Change Model perspective. Paper-and-pencil questionnaires were administered to N = 47 participants aged between 19 and 32 before and after watching either Cowspiracy (experimental group, n = 26) or Planet Earth (control group, n = 21). Controlling for the influence of predisposing factors (sociodemographic characteristics gender, age, and socioeconomic status), the results show that watching a popular documentary about the environmental impact of meat production (Cowspiracy) can have a significant effect on the awareness of the environmental consequences of meat consumption, the attitude toward eating less meat, and the intention to reduce meat consumption of young (almost) daily meat eaters. However, results should be interpreted with caution, given the preliminary nature of our study

Coping with distress among adolescents: Effectiveness of personal narratives on support websites

Compartir, leer y responder a narraciones personales en webs de apoyo entre iguales puede tanto fortalecer como amenazar la confianza de los adolescentes para hacer frente a los acontecimientos estresantes (es decir, la autoeficacia como estrategia de afrontamiento). Los principios de la escritura expresiva, el intercambio social de emociones, la persuasión narrativa y los efectos en uno mismo pueden proporcionar información sobre la forma en que esas acciones pueden relacionarse con la autoeficacia como estrategia de afrontamiento. Mediante una encuesta transversal en línea con 311 adolescentes de habla holandesa de entre 14 y 18 años, este artículo explora cómo estas acciones y los motivos del apoyo social (es decir, la búsqueda de información y la búsqueda de apoyo emocional) se relacionan con la autoeficacia de los adolescentes como estrategia de afrontamiento tras usar la web de apoyo entre iguales. Los resultados muestran que la experiencia de los usuarios al leer y responder a narraciones personales no estaba relacionada con su autoeficacia de afrontamiento. Sin embargo, se encontró una relación negativa entre la experiencia de compartir una narración personal y la autoeficacia, por lo que los usuarios no percibieron que el sitio web fuera útil para su confianza general a la hora de hacer frente a acontecimientos estresantes. No obstante, esta relación negativa se invirtió cuando también tenían el objetivo de encontrar apoyo emocional con sus igualesSharing, reading and responding to personal narratives on peer-to-peer support websites may provide adolescents with informational and emotional support to feel more confident in coping with stressful events. However, their use may also pose a threat to adolescents’ coping self-efficacy. Principles of expressive writing, social sharing of emotions, narrative persuasion and self-effects may provide insight in how these actions may both positively and negatively relate to coping self-efficacy. By using a cross-sectional online survey with 311 Dutch-speaking adolescents between the ages of 14 and 18, this article explores how these actions and social support motives (i.e. information-seeking and emotional supportseeking) are related to adolescents’ perceptions about the usefulness of these websites to their coping self-efficacy. The results showed a positive relation between adolescents’ social support motives and their belief in the usefulness of these websites to their coping self-efficacy. Therefore, we conclude that it may be an effective coping strategy for many adolescents. There was a negative relation between experience with sharing a personal narrative and coping self-efficacy, meaning that these users did not perceive the website to be helpful to their overall confidence in coping with stressful events. However, this negative relation was reversed when they were motivated to find emotional support with similar other

Food purchasing and preparation patterns by gender during the COVID-19 lockdown in Chilean workers/Patrones de compra y preparación de alimentos según género durante la cuarentena por COVID-19 en trabajadores chilenos

The COVID-19 pandemic has increased the demands that workers face regarding household food-related tasks, such as grocery shopping and cooking. The literature shows that there are differences in these demands by gender, but also based on other sociodemographic characteristics, such as schooling level. The aim of this study was to compare food purchasing and preparation patterns by gender in Chilean workers, before the COVID-19 lockdown and during the first six weeks of lockdown. The study was cross-sectional, and data was collected for the first wave of a multi-country study in April 2020. The sample was composed of 317 participants who were employed during lockdown (67.8% women, mean age of 38.14). Participants answered sociodemographic questions and reported their food purchasing and preparing practices before and during lockdown. Analysis of comparison of proportions was used. On average, during lockdown, men increased their involvement in grocery shopping while women cooked more. Overall, female workers have turned to food-related tasks more often during the pandemic than male workers. This study shows the extent to which workers have changed their degree of involvement in food-related tasks, accounting for conditions such as gender roles, schooling level and working from home. These findings can inform interventions and policies that reinforce advantageous changes brought on by lockdown measures (e.g., home-cooking) to contribute to workers’ and their families’ food-related well-being during and in the aftermath of the pandemic

An evaluation of the COVID-19 pandemic and perceived social distancing policies in relation to planning, selecting, and preparing healthy meals: an observational study in 38 countries worldwide

Objectives: To examine changes in planning, selecting, and preparing healthy foods in relation to personal factors (time, money, stress) and social distancing policies during the COVID-19 crisis. Methods: Using cross-sectional online surveys collected in 38 countries worldwide in April-June 2020 (N = 37,207, Mage 36.7 SD 14.8, 77% women), we compared changes in food literacy behaviors to changes in personal factors and social distancing policies, using hierarchical multiple regression analyses controlling for sociodemographic variables. Results: Increases in planning (4.7 SD 1.3, 4.9 SD 1.3), selecting (3.6 SD 1.7, 3.7 SD 1.7), and preparing (4.6 SD 1.2, 4.7 SD 1.3) healthy foods were found for women and men, and positively related to perceived time availability and stay-at-home policies. Psychological distress was a barrier for women, and an enabler for men. Financial stress was a barrier and enabler depending on various sociodemographic variables (all p < 0.01). Conclusion: Stay-at-home policies and feelings of having more time during COVID-19 seem to have improved food literacy. Stress and other social distancing policies relate to food literacy in more complex ways, highlighting the necessity of a health equity lens

Call for emergency action to restore dietary diversity and protect global food systems in times of COVID-19 and beyond: Results from a cross-sectional study in 38 countries

Background: The COVID-19 pandemic has revealed the fragility of the global food system, sending shockwaves across countries' societies and economy. This has presented formidable challenges to sustaining a healthy and resilient lifestyle. The objective of this study is to examine the food consumption patterns and assess diet diversity indicators, primarily focusing on the food consumption score (FCS), among households in 38 countries both before and during the first wave of the COVID-19 pandemic. Methods: A cross-sectional study with 37 207 participants (mean age: 36.70 ± 14.79, with 77 % women) was conducted in 38 countries through an online survey administered between April and June 2020. The study utilized a pre-tested food frequency questionnaire to explore food consumption patterns both before and during the COVID-19 periods. Additionally, the study computed Food Consumption Score (FCS) as a proxy indicator for assessing the dietary diversity of households. Findings: This quantification of global, regional and national dietary diversity across 38 countries showed an increment in the consumption of all food groups but a drop in the intake of vegetables and in the dietary diversity. The household's food consumption scores indicating dietary diversity varied across regions. It decreased in the Middle East and North Africa (MENA) countries, including Lebanon (p < 0.001) and increased in the Gulf Cooperation Council countries including Bahrain (p = 0.003), Egypt (p < 0.001) and United Arab Emirates (p = 0.013). A decline in the household's dietary diversity was observed in Australia (p < 0.001), in South Africa including Uganda (p < 0.001), in Europe including Belgium (p < 0.001), Denmark (p = 0.002), Finland (p < 0.001) and Netherland (p = 0.027) and in South America including Ecuador (p < 0.001), Brazil (p < 0.001), Mexico (p < 0.0001) and Peru (p < 0.001). Middle and older ages [OR = 1.2; 95 % CI = [1.125–1.426] [OR = 2.5; 95 % CI = [1.951–3.064], being a woman [OR = 1.2; 95 % CI = [1.117–1.367], having a high education (p < 0.001), and showing amelioration in food-related behaviors [OR = 1.4; 95 % CI = [1.292–1.709] were all linked to having a higher dietary diversity. Conclusion: The minor to moderate changes in food consumption patterns observed across the 38 countries within relatively short time frames could become lasting, leading to a significant and prolonged reduction in dietary diversity, as demonstrated by our findings.Revisión por pare

Sex disparities in food consumption patterns, dietary diversity and determinants of self-reported body weight changes before and amid the COVID-19 pandemic in 10 Arab countries

Background: The COVID-19 pandemic along with its confinement period boosted lifestyle modifications and impacted women and men differently which exacerbated existing gender inequalities. The main objective of this paper is to assess the gender-based differentials in food consumption patterns, dietary diversity and the determinants favoring weight change before and amid the COVID-19 pandemic among Arab men and women from 10 Arab countries. Methods: A cross-sectional study was conducted based on a convenience sample of 12,447 households' family members (mean age: 33.2 ± 12.9; 50.1% females) and information from participants aged 18 years and above was collected about periods before and during the pandemic. Results: Findings showed that, during the COVID-19 period, the dietary diversity, declined by 1.9% among females compared to males (0.4%) (p < 0.001) and by 1.5% among overweight participants (p < 0.001) compared to their counterparts. Conclusions: To conclude, gender-sensitive strategies and policies to address weight gain and dietary diversity during emergent shocks and pandemics are urgently needed in the region.This research was funded by the Research Foundation Flanders (G047518N) and Flanders Innovation and Entrepreneurship (HBC.2018.0397).
