The role of weight perceptions and their impact on health and well‐being: A multiple mediation model
Get PDFThe present study analyses the role of weight distortion and weight self-criticism in explaining the relationship between actual weight and perceived health, well-being, body satisfaction and emotional eating. Eight hundred and six individuals were selected from a national study on nutrition. They were divided into two groups according to self-reported dieting. A questionnaire measuring the outcome variables was implemented. Weight distortion and self-criticism were calculated using actual, estimated and desired BMI. A multiple mediation model was estimated using structural equation modelling. A valid model was obtained in which weight self-criticism is a partial mediator of the relationship between weight and body satisfaction and a full mediator of the relationship between weight and emotional eating for the non-dieter group. For the dieter group, full mediation of weight self-criticism is observed in the relationships between weight and health, well-being and body satisfaction. For weight distortion, no mediation effect is found in either group. The results highlight the importance of weight perceptions in understanding the influence of body weight on several aspects of health and well-being. The type of weight perception is also relevant. A critical attitude towards weight is more determinant than the distortion in weight appraisal.Fundação para a Ciência e Tecnologia - FCTinfo:eu-repo/semantics/publishedVersio

Sexual expression in old age: How older adults from different cultures express sexually?
No full textObjective This study aims to analyze how older adults express themselves sexually. For this purpose, a qualitative research was
carried out, which analyzes their perspectives at a cross-cultural level.
Methods Four hundred ninety-five older participants, aged 65 to 98 years, were interviewed. Participants were of three different
nationalities and lived in the community. All the interviews went through the process of verbatim transcription and subsequent
content analysis.
Results A content analysis produced nine themes: tenderness and care (k = .91, p < .01); altruism and gratitude (k = .81, p < .01);
attractiveness (k = 94, p < .01); positive communication (k = .89, p < .01); sexual activity (k = .88, p < .01); good health and
physical condition (k = .96, p < .01); supportive relationship (k = .84, p < .01); eroticism (k = .94, p < .01); and feeling active
and alive (k = .92, p < .01).
Conclusions This study stressed different ways on expressing sexuality in old age and underlined the importance of tenderness
and care and eroticism for older adults who are sexually active.Fundação para a Ciência e Tecnologia - FCTinfo:eu-repo/semantics/publishedVersio
Forebrain transcriptional response to transient changes in circulating androgens in a cichlid fish
Get PDFIt has been hypothesized that androgens respond to the social interactions as a way to adjust the behavior of individuals to the challenges of the social environment in an adaptive manner. Therefore, it is expected that transient changes in circulating androgen levels within physiological scope should impact the state of the brain network that regulates social behavior, which should translate into adaptive behavioral changes. Here, we examined the effect that a transient peak in androgen circulating levels, which mimics socially driven changes in androgen levels, has on the forebrain state, which harbors most nuclei of the social decision-making network. For this purpose, we successfully induced transient changes in circulating androgen levels in an African cichlid fish (Mozambique tilapia, Oreochromis mossambicus) commonly used as a model in behavioral neuroendocrinology by injecting 11-ketotestosterone or testosterone, and compared the forebrain transcriptome of these individuals to control fish injected with vehicle. Forebrain samples were collected 30 min and 60 min after injection and analyzed using RNAseq. Our results showed that a transient peak in 11-ketotestosterone drives more accentuated changes in forebrain transcriptome than testosterone, and that transcriptomic impact was greater at the 30 min than at the 60 min post-androgen administration. Several genes involved in the regulation of translation, steroid metabolism, ion channel membrane receptors, and genes involved in epigenetic mechanisms were differentially expressed after 11-ketotestosterone or testosterone injection. In summary, this study identified specific candidate genes that may regulate socially driven changes in behavioral flexibility mediated by androgens.Fundação para a Ciência e Tecnologia - FCTinfo:eu-repo/semantics/publishedVersio
