“…The German version of the DEBQ [ 12 ] measures three dimensions of eating style with 30 items: the degree of restrained, emotional, and external eating. Education was assessed according to the internationally comparable CASMIN-index [ 24 ] as previously reported for the NFS cohort [ 25 ]. The SF-8 measures the eight health profile dimensions of the SF-36 [ 26 ] in a comparatively short test using one item per dimension: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions.…”

Associations between Taste and Smell Sensitivity, Preference and Quality of Life in Healthy Aging—The NutriAct Family Study Examinations (NFSE) Cohort

Taste and smell function decline with age, with robust impairment in the very old. Much less is known about taste and smell function in young and middle aged. We investigated taste and smell sensitivity via thresholds in a sub-sample of the NutriAct Family Study (NFS), the NFS Examinations cohort (NFSE; N = 251, age M = 62.5 years). We examined different aspects relating to taste and smell function: the degree to which taste and smell sensitivity relate to another and to taste and smell preferences, the role of gender and age, as well as effects on Quality of Life (QoL). Taste thresholds were highly correlated, but no correlation was observed between taste and smell thresholds and between thresholds and preference. Women were more sensitive for both taste and smell than men. We found no effect of age on sensitivity and no effect of sensitivity on QoL. All null findings were complemented by Bayesian statistics. Together our results indicate the independence of taste and smell despite their overlap during sensorial experiences. We found no evidence for age-related sensory decline, which could be due to our sample’s characteristics of non-clinical volunteers with good dental health and 93% non-smokers.

“…Thus, participants will be relatively experienced in terms of participating in research studies and potentially biased towards a generally higher interest in nutrition-related topics. In addition, the NFS participant pool shows a comparably high level of education [ 45 ], which might further limit the representativeness of the sample. As the enrollment in the present study depends on the agreement and cooperation of both partners, there might also occur a selection bias towards functional relationships.…”

Background Eating in absence of hunger is quite common and often associated with an increased energy intake co-existent with a poorer food choice. Intuitive eating (IE), i.e., eating in accordance with internal hunger and satiety cues, may protect from overeating. IE, however, requires accurate perception and processing of one’s own bodily signals, also referred to as interoceptive sensitivity. Training interoceptive sensitivity might therefore be an effective method to promote IE and prevent overeating. As most studies on eating behavior are conducted in younger adults and close social relationships influence health-related behavior, this study focuses on middle-aged and older couples. Methods The present pilot randomized intervention study aims at investigating the feasibility and effectiveness of a 21-day mindfulness-based training program designed to increase interoceptive sensitivity. A total of N = 60 couples participating in the NutriAct Family Study, aged 50–80 years, will be recruited. This randomized-controlled intervention study comprises three measurement points (pre-intervention, post-intervention, 4-week follow-up) and a 21-day training that consists of daily mindfulness-based guided audio exercises (e.g., body scan). A three-arm intervention study design is applied to compare two intervention groups (training together as a couple vs. training alone) with a control group (no training). Each measurement point includes the assessment of self-reported and objective indicators of interoceptive sensitivity (primary outcome), self-reported indicators of intuitive and maladaptive eating (secondary outcomes), and additional variables. A training evaluation applying focus group discussions will be conducted to assess participants’ overall acceptance of the training and its feasibility. Discussion By investigating the feasibility and effectiveness of a mindfulness-based training program to increase interoceptive sensitivity, the present study will contribute to a deeper understanding of how to promote healthy eating in older age.

“…For instance, one family member may influence household participation in green practices such as waste management, which requires a certain degree of co-action between household members [56]. Only a few studies have analyzed the ethical behavior of the consumer by considering the topic at the couple level or the family level [19,20]. Grønhøj [18] studied decision making about ecological practices within the family.…”

“…They often involve both spouses and even sometimes the children, who are increasingly involved in this family decision making process because of their awareness of ethical issues in their daily lives. Only a few studies have considered the dynamics of influence within couples regarding ethical purchase decisions [18][19][20]. Compared to an individual decision, a joint decision often implies concessions from one partner when the points of view on the best product to choose or the purchase criteria differ.…”

Couple Ethical Purchase Behavior and Joint Decision Making: Understanding the Interaction Process and the Dynamics of Influence

We present in this paper a qualitative study of couple ethical purchasing behavior, based on interviews with French consumers. The analysis of joint decision making allows us to distinguish between ethical couples who favor the choice of ethical products when making purchase decisions together and unethical couples who do not. Our results show that ethical couples are characterized by a positive exchange of information, use of verbal and tactical persuasion strategies, and trust in the knowledge of the partner, while unethical couples are characterized by a negative exchange of information, difficulties with joint decision making, and conflict-minimizing strategy. Time, money, and pleasure appear as the most critical factors restricting couples’ purchase of ethical products. Our research provides the first empirical evidence about the dynamics of influence of one partner over the other within couples regarding ethical purchasing behavior.
