(2019)A health effect is a credence quality feature which is difficult for consumers to detect, and they need to be convinced of its trustworthiness. This study explores the role of trust-related arguments in Finnish, German, and British consumers' willingness to try a novel health-enhancing, non-edible product. Scientific evidence in particular would convince consumers, particularly Finnish ones, to try a product. Receiving recommendations from other users was more important for younger than for older respondents when it came to trying this type of product. Different marketing strategies may be needed to convince potential users of the benefits of a novel product.

(2020)Dupilumab, a fully human monoclonal antibody against interleukin-4 receptor alpha, is approved as add-on maintenance treatment for inadequately controlled type 2 severe asthma. This systematic review evaluated the efficacy, safety and economic impact of dupilumab compared to standard of care for uncontrolled severe asthma. PubMed, EMBASE and Cochrane Library were searched for RCTs and health economic evaluations. Critical and important asthma-related outcomes were evaluated. The risk of bias and the certainty of the evidence were assessed using GRADE. Three RCTs including 2735 subjects >12 years old and 24-52 weeks of follow-up were included. Dupilumab reduced with high certainty severe asthma exacerbations (Incidence rate ratio 0.51; 95% CI 0.45-0.59) and the percentage use of oral corticosteroid use (mean difference (MD) -28.2 mg/d; 95% CI -40.7 to -15.7). Asthma control (ACQ-5), quality of life (AQLQ) and rescue medication use [puffs/d] improved, without reaching the minimal important clinical difference: ACQ-5 MD -0.28 (95% CI -0.39 to -0.17); AQLQ MD +0.28 (95% CI 0.20-0.37); and rescue medication MD -0.35 (95% CI -0.73 to +0.02). FEV1 increased (MD +0.15; 95% CI +0.11 to +0.18) (moderate certainty). There was an increased rate of dupilumab-related adverse events (AEs) (moderate certainty) and of drug-related serious AEs (low certainty). The incremental cost-effectiveness ratio of dupilumab versus standard therapy was 464 000$/QALY (moderate certainty). More data on long-term safety are needed both for children and for adults, together with more efficacy data in the paediatric population.

(2019)Although the demand for organic food is growing globally, the mainstream consumption of organic food is far less. The present study attempts to understand underlying reasons for consumer resistance toward consuming organic food using the theoretical framework of innovation resistance theory (IRT). The study further examines the association between different consumer barriers and purchase decisions (purchase intentions, ethical consumption intentions, and choice behaviour) at different levels of buying involvement and environmental concerns. The collected data, consisting of 452 consumers, were analyzed by structural equation modeling approach. The results showed that value is the major barrier influencing purchase intentions and ethical consumption intentions. Ethical consumption and purchase intention were found to have direct influence on choice behaviour. Additionally, the relationship between ethical consumption intention and choice behaviour is mediated by purchase intention. However, no significant differences have emerged based on level of buying involvement and environment concerns. The findings of the study provide insight into public policymakers, marketers, suppliers, and consumer associations by enhancing their current understanding of buying behaviour of the growing organic food community.

(2020)Although consumer interest in organic food has risen over time, resulting in a generally positive attitude toward these organic food products, scholarly research suggests a comparatively low volume of its consumption in the market. This has resulted in an urgent need to study the motivations which enhance consumers' proclivity to purchase food items produced organically. The current research attempts to understand potential associations between motivations (intrinsic and extrinsic), attitude, and buying behaviour towards organic food. Self-determination theory (SDT) was applied to develop a theoretically grounded framework which was evaluated with 378 organic food consumers. The hypotheses were tested by analyzing the data through structural equation modelling (SEM), wherein environmental concerns and trust were the moderating variables. The study results demonstrate the significant influence of intrinsic motivation, integrated and external regulation on consumer attitude, and buying behaviour. But, attitude had no significant association with buying behaviour. The findings indicate consumers' motivation may be stimulated to encourage higher frequencies of purchasing organic food by emphasizing values that reflect motivations arising from ethical or green consumerism, health, and social benefits. Furthermore, policymakers should focus on avenues to integrate organic food as permanent parts of individual lives and a socially exalting behavioral action.
