Aims/hypothesis Ceramide lipids have a role in the development of insulin resistance, diabetes and risk of cardiovascular disease. Here we investigated four ceramides and their ratios to find the best predictors of incident diabetes. Methods A validated mass-spectrometric method was applied to measure Cer(d18:1/16:0), Cer(d18:1/18:0), Cer(d18:1/ 24:0) and Cer(d18:1/24:1) from serum or plasma samples. These ceramides were analysed in a population-based risk factor study (FINRISK 2002, n = 8045), in a cohort of participants undergoing elective coronary angiography for suspected stable angina pectoris (Western Norway Coronary Angiography Cohort [WECAC], n = 3344) and in an intervention trial investigating improved methods of lifestyle modification for individuals at high risk of the metabolic syndrome (Prevent Metabolic Syndrome [PrevMetSyn], n = 371). Diabetes risk score models were developed to estimate the 10 year risk of incident diabetes. Results Analysis in FINRISK 2002 showed that the Cer(d18:1/18:0)/Cer(d18:1/16:0) ceramide ratio was predictive of incident diabetes (HR per SD 2.23, 95% CI 2.05, 2.42), and remained significant after adjustment for several risk factors, including BMI, fasting glucose and HbA 1c (HR 1.34, 95% CI 1.14, 1.57). The finding was validated in the WECAC study (unadjusted HR 1.81, 95% CI 1.53, 2.14; adjusted HR 1.39, 95% CI 1.16, 1.66). In the intervention trial, the ceramide ratio and diabetes risk scores significantly decreased in individuals who had 5% or more weight loss.Markku J.

“…The underlying principle is to understand users and integrate this understanding into developing systems that help users to achieve specific objectives that could be health and well-being or lifestyle-related. This could be through design strategies that help people to change their everyday behaviours (Consolvo, McDonald, & Landay, 2009), investigating how systems' perceived persuasiveness, and the design of persuasive features influence users' adoption, continuance intention, and adherence to these systems (Kelders et al, 2012;Lehto & Oinas-Kukkonen, 2015;Lehto, Oinas-Kukkonen, Pätiälä, & Saarelma, 2012), or analysing the persuasive user experiences of a BCSS, for instance, for the prevention of metabolic syndrome (Karppinen et al, 2016). Other previous research includes, for example, analysing how the features implemented in a persuasive system are compatible with users' goals and affect system usage (Ebermann & Brauer, 2016), exploring the need for and role of reflection in persuasive systems design (Halttu & Oinas-Kukkonen, 2017), using persuasive principles to analyse carbon management systems (Corbett, 2013), and to study attitudes towards fire safety (Chittaro & Zangrando, 2010) among many others.…”

Persuasive systems in different domains have been used to support people in changing their behaviours. These systems motivate desirable behaviour in users by providing relevant information, tracking user progress, and giving them feedback. This study investigates the persuasive features of a web-based information system that supports the enforcement of user commitments. A structural equation modelling approach and analysis of open text responses are used to identify the factors that affect the intention to continue to use the system, to gather users' perspectives on how the system helps them to stick to their goals and the improvements that could be made. Data (N = 227) collected from the system's users is tested against the proposed research model. The results show that 30% of users' continuance intention is explained by the implemented persuasive software feature categories (computer-human dialogue support, primary task support, perceived credibility, and social support) and perceived competence. Of these categories, primary task support has the strongest effect on perceived competence and continuance intention. The results also reveal how the system helps users to be consistent in their goals and the lack of specialized social support features. The study concludes with a discussion and recommendations for future research.
