Commentary on muscle dysmorphia as an addiction: A response to Grant (2015) and Nieuwoudt (2015)

Background: Following the publication of our paper ‘Muscle Dysmorphia: Could it be classified as an addiction to body image?’ in the Journal of Behavioral Addictions, two commentaries by Jon Grant and Johanna Nieuwoudt were published in response to our paper. Method: Using the ‘addiction components model’, our main contention is that muscle dysmorphia (MD) actually comprises a number of different actions and behaviors and that the actual addictive activity is the maintaining of body image via a number of different activities such as bodybuilding, exercise, eating certain foods, taking specific drugs (e.g., anabolic steroids), shopping for certain foods, food supplements, and purchase or use of physical exercise accessories. This paper briefly responds to these two commentaries. Results: While our hypothesized specifics relating to each addiction component sometimes lack empirical support (as noted explicitly by both Nieuwoudt and Grant), we still believe that our main thesis (that almost all the thoughts and behaviors of those with MD revolve around the maintenance of body image) is something that could be empirically tested in future research by those who already work in the area. Conclusions: We hope that the ‘Addiction to Body Image’ model we proposed provides a new framework for carrying out work in both empirical and clinical settings. The idea that MD could potentially be classed as an addiction cannot be negated on theoretical grounds as many people in the addiction field are turning their attention to research in new areas of behavioral addiction

Adverse childhood experiences and suicide attempts in morbidly obese adults

Introdução: As tentativas de suicídio surgem frequentemente associadas a problemas alimentares, tanto anorexia quanto bulimia. Do mesmo modo, tem-se verifi cado uma elevada ocorrência de suicídio entre obesos. Investigações têm mostrado que a adversidade na infância pode ser um fator de risco para as tentativas de suicídio. Objetivos: Caracterizar e compreender a relação entre experiências de adversidade na infância e tentativas de suicídio em 100 obesos mórbidos candidatos a cirurgia bariátrica. Métodos: Um total de 100 pacientes foram selecionados de setembro de 2007 a outubro de 2007 e de janeiro de 2008 a janeiro de 2009, sendo que 20 pacientes eram do sexo feminino. A média de idade era de 38,89±9,87 anos, e a média do peso máximo era de 136,43±14 kg. O Questionário da História de Adversidade na Infância foi utilizado para avaliar experiências adversas. Resultados: 88% dos pacientes relataram a existência de pelo menos uma experiência de adversidade na infância, e 25% relataram já ter realizado pelo menos uma tentativa de suicídio. A adversidade na infância esteve associada a um risco aumentado para realizar tentativas de suicídio (odds ratio = 2,026). Conclusão: Esses dados devem ser levados em consideração na avaliação e no acompanhamento desses pacientes.Introduction: Suicide attempts are often associated with eating disorders, both anorexia and bulimia. Likewise, a high incidence of suicide has been observed among obese patients. Previous studies have shown that adverse experiences in childhood may be a risk factor for suicide attempts. Objectives: To characterize and to understand the relationship between adverse experiences and suicide attempts in 100 morbidly obese patients referred for bariatric surgery. Methods: A total of 100 patients were selected from September 2007 to October 2007 and from January 2008 to January 2009. Of these, 20 patients were females. Mean age was 38.89±9.87 years, and mean maximum weight was 136.43±14 kg. The Portuguese version of the Family ACE (Adverse Childhood Experiences) Questionnaire was used to assess the occurrence of adverse events. Results: 88% of the patients reported the existence of at least one adverse experience in childhood, and 25% reported at least one previous suicide attempt. Adversity in childhood was associated with an increased risk for suicide attempts (odds ratio = 2.026). Conclusion: These data should be taken into account in the assessment and monitoring of these patients.Fundação para a Ciência e a Tecnologia (FCT); (SFRH/BD/37069/2007)

Childhood emotional trauma and cyberbullying perpetration among emerging adults: a multiple mediation model of the role of problematic social media use and psychopathology

Research suggests that a small minority of social media users experience problems as a result of their online use. The purpose of the present study was to examine the association of cyberbullying perpetration and problematic social media use with childhood emotional trauma, Cluster B (narcissistic, histrionic, antisocial, and borderline) personality traits, dissociative experiences (DEs), depression, and self-esteem in a nonclinical undergraduate sample. A total of 344 university students volunteered to complete a questionnaire that included measures on the aforementioned dimensions. Thirty-eight percent of the participants had emotional neglect and 27% had emotional abuse, while 44% of them demonstrated at least one cyberbullying perpetration behavior. Results indicated that cyberbullying perpetrators had higher scores on problematic social media use, dissociative experiences, Cluster B traits, depression and childhood emotional trauma, and lower on self-esteem. Path analysis demonstrated that, while adjusting for gender and age, childhood emotional trauma was directly and indirectly associated with cyberbullying perpetration via Cluster B traits. Moreover, depression and dissociation were directly associated with problematic social media use. The findings of this study emphasize the important direct role of childhood emotional trauma and pathological personality traits on cyberbullying perpetration

Child neglect in one-child families from Suzhou City of mainland China

Background The one-child policy introduced in China in 1979 has led to far-reaching changes in socio-demographic characteristics. Under this policy regime, each household has few children. This study aims to describe the prevalence of child neglect in one-child families in China and to examine the correlates of child neglect. Methods A cross-sectional study of 2044 children aged 6 to 9 years and recruited from four primary schools in Suzhou City, China was conducted. Neglect subtypes were determined using a validated indigenous measurement scale reported by parents. Child, parental and family characteristics were obtained by questionnaires and review of social security records. Linear regression analyses were performed to estimate the associations between these factors and the subtypes of child neglect. Results The prevalence of child any neglect was 32.0% in one child families in Suzhou City, China. Supervisory (20.3%) neglect was the most prevalent type of child neglect, followed by emotional (15.2%), physical (11.1%), and educational (6.0%) neglect After simultaneous adjustment to child and family characteristics and the school factor, boys, children with physical health issues and cognitive impairment, younger and unemployed mother, were positively associated with neglect subtypes. We also found that parents with higher education and three-generation families were negatively associated with neglect. Conclusion The rates of child neglect subtypes vary across different regions in China probably due to the different policy implementation and socio-economic levels, with a lower level of physical and educational neglect and a higher level of emotional neglect in this study. The three-generation family structure was correlates of neglect which may be unique in one child families. This indicates that future intervention programs in one-child families should target these factorsBioMed Central open acces

As Proficient as Adults : Distribution of Children's Knowledge of Wild Edible Plants in an Arid Environment in Madagascar

Altres ajuts: acords transformatius de la UABUnidad de excelencia María de Maeztu CEX2019-000940-MIn drylands, where resources are scarce, wild edible plant (WEP) knowledge is crucial to overcome food scarcity. Understanding the distribution pattern of local ecological knowledge (LEK) about WEP and identifying knowledge holders are key steps to assessing the resilience and vulnerability of knowledge systems. However, little is known about how WEP knowledge is distributed across life stages and gender of people living in arid regions. Here, we study the distribution of WEP knowledge within a small-scale society from southwestern Madagascar, a region known for its dry climate and related food crises. We worked with Tanalana male and female children and adults using semi-structured interviews and free listings. Tanalana people display a sophisticated LEK adapted to the extreme environment in which they live, with a distinct distribution pattern regarding theoretical and practical knowledge across life stages and gender. While women and men cited similar WEP, children and adults cited different sets of WEP, suggesting they hold differentiated bodies of theoretical knowledge, however our results suggest similarity in practical knowledge across life-stage and gender. We argue that resource limitation and food scarcity might be so pervasive in the area that extensive sharing of knowledge on WEP could be an adaptation to the extremely dry environment
