Cue Reactivity to Variously Processed Foods

The NOVA classification system categorizes foods according to their level of processing to differentiate between industrially prepared, or Ultra-Processed (UP), and home-prepared, or Processed (P) and Minimally Processed (MP), foods. Whereas P and MP are recommended as part of a healthy diet, UP foods are considered unhealthy and a contributing factor to global, rising obesity rates. However, food addiction investigators include examples of both UP and P foods within their nomenclature of Highly Processed, addictive foods. Our study is the first to compare the potential addictiveness of a priori classified foods into UP vs P vs MP categories. We presented 169 women with a collection of 45 UP, P, and MP food pictures and recorded their subjective motivational reactivity to each picture. Analyses of covariance (ANCOVA) revealed that Yale Food Addiction Scale 2.0 (YFAS 2.0; Gearhardt et al., 2016) scores potentiated reactivity to both UP and P pictures, but not MP pictures. In addition, although both UP and P foods produced greater motivational reactivity than MP foods, UP foods elicited significantly greater reactivity than P foods. Our findings concur with previous suggestions that foods can be classified along a continuum of addictiveness potential, but our findings are the first to demonstrate that such classification might be accomplished by following the NOVA classification system. The findings also imply that nutrition experts may need to refine their NOVA classification system and, perhaps, even their healthy diet recommendations

Validation of the Spanish version of the body image acceptance and action questionnaire (BI-AAQ-Spanish): Measurement invariance across cultures.

The purpose of this study was to assess the psychometric properties of a Spanish version of the Body Image Acceptance and Action Questionnaire (BI-AAQ) and its recently developed 5-item version, the BI-AAQ-5. The BI-AAQ measures psychological flexibility/inflexibility regarding body image. A sample of Spanish adults (n = 938) completed the BI-AAQ and a battery of measures (including body mass index, psychological flexibility, exposure to and internalization of sociocultural body image expectations, body dissatisfaction, and eating disorder symptoms). Measurement invariance was tested against a U.S. American adult sample (n = 866) that completed the English version of the BI-AAQ. The unidimensional factor structure of the BI-AAQ and BI-AAQ-5 was replicated in both samples using confirmatory factor analysis, with model fit indexes ranging from adequate (e.g., CFI = 0.95) to excellent (e.g., CFI = 0.99). Internal consistency was good for both instruments across samples (α = 0.90 to 0.97). Measurement invariance analyses confirmed full configural and metric invariance and scalar partial invariance. The Spanish BI-AAQ and BI-AAQ-5 showed clear evidence of convergent and incremental construct validity. Both instruments’ scores correlated substantively with theoretically related variables. In addition, the results of a conditional process analysis showed that body-image psychological flexibility measured with either instrument moderated the mediated effect of pressure to conform to cultural ideals of body image on disordered eating through internalization of body image ideals and body dissatisfaction. We concluded both instruments are likely suitable for conducting cross-cultural research with Spanish and English-speaking samples.Funding for open access charge: Universidad de Jaén

Body Mass Index and Nationality (Argentine vs. Spanish) Moderate the Relationship Between Internalization of the Thin Ideal and Body Dissatisfaction: A Conditional Mediation Model

It is believed that Women’s exposure to Western sociocultural pressures to attain a “thin-ideal” results in the internalization of a desire to be thin that consequently leads to body dissatisfaction (BD). It is also well documented that body mass index (BMI; kg/m2) correlates with BD. We tested for the first time a conditional mediation model where thin-ideal Awareness predicted BD through Internalization of the thin ideal and the path from Internalization to BD was hypothesized to be moderated by BMI and Nationality (Argentine vs. Spanish). The model was tested with a sample of 499 young women (age = 18 to 29) from Argentina (n = 290) and Spain (n = 209). Awareness and internalization were measured with the SATAQ-4 (Schaefer et al., 2015) and BD was measured with the BSQ (Cooper et al., 1987). The model was analyzed using PROCESSv3.1 (Hayes, 2018). As hypothesized, thin-ideal awareness predicted BD through internalization and the path from internalization to BD was moderated by BMI and nationality. Specifically, internalization predicted BD at all level of BMI and in both samples, but the relationship between internalization and BD increased with BMI and was also stronger among Spaniards than Argentines. We argue that the findings are congruent with theories that predict that economic development and modernization contribute to normative female BD through internalization of the thin ideal and that upward social comparisons or cognitive discrepancy between self-perceived body image and the sociocultural thin ideal interacts synergistically with thin-ideal internalization to increase BD

Productivity trends and collaboration patterns: A diachronic study in the eating disorders field

[EN] Objective The present study seeks to extend previous bibliometric studies on eating disorders (EDs) by including a time-dependent analysis of the growth and evolution of multi-author collaborations and their correlation with ED publication trends from 1980 to 2014 (35 years). Methods Using standardized practices, we searched Web of Science (WoS) Core Collection (WoSCC) (indexes: Science Citation Index-Expanded [SCIE], & Social Science Citation Index [SSCI]) and Scopus (areas: Health Sciences, Life Sciences, & Social Sciences and Humanities) to identify a large sample of articles related to EDs. We then submitted our sample of articles to bibliometric and graph theory analyses to identify co-authorship and social network patterns. Results We present a large number of detailed findings, including a clear pattern of scientific growth measured as number of publications per five-year period or quinquennium (Q), a tremendous increase in the number of authors attracted by the ED subject, and a very high and steady growth in collaborative work. Conclusions We inferred that the noted publication growth was likely driven by the noted increase in the number of new authors per Q. Social network analyses suggested that collaborations within ED follow patters of interaction that are similar to well established and recognized disciplines, as indicated by the presence of a ¿giant cluster¿, high cluster density, and the replication of the ¿small world¿ phenomenon¿the principle that we are all linked by short chains of acquaintances.This work was performed with a subsidy from Universidad Catolica de Valencia "San Vicente Martir" to resarch group INDOTEI: Evaluacion de la Ciencia, for the years 2016-2017.

Choice of the initial antiretroviral treatment for HIV-positive individuals in the era of integrase inhibitors

BACKGROUND: We aimed to describe the most frequently prescribed initial antiretroviral therapy (ART) regimens in recent years in HIV-positive persons in the Cohort of the Spanish HIV/AIDS Research Network (CoRIS) and to investigate factors associated with the choice of each regimen. METHODS: We analyzed initial ART regimens prescribed in adults participating in CoRIS from 2014 to 2017. Only regimens prescribed in >5% of patients were considered. We used multivariable multinomial regression to estimate Relative Risk Ratios (RRRs) for the association between sociodemographic and clinical characteristics and the choice of the initial regimen. RESULTS: Among 2874 participants, abacavir(ABC)/lamivudine(3TC)/dolutegavir(DTG) was the most frequently prescribed regimen (32.1%), followed by tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC)/elvitegravir(EVG)/cobicistat(COBI) (14.9%), TDF/FTC/rilpivirine (RPV) (14.0%), tenofovir alafenamide (TAF)/FTC/EVG/COBI (13.7%), TDF/FTC+DTG (10.0%), TDF/FTC+darunavir/ritonavir or darunavir/cobicistat (bDRV) (9.8%) and TDF/FTC+raltegravir (RAL) (5.6%). Compared with ABC/3TC/DTG, starting TDF/FTC/RPV was less likely in patients with CD4100.000 copies/mL. TDF/FTC+DTG was more frequent in those with CD4100.000 copies/mL. TDF/FTC+RAL and TDF/FTC+bDRV were also more frequent among patients with CD4<200 cells//muL and with transmission categories other than men who have sex with men. Compared with ABC/3TC/DTG, the prescription of other initial ART regimens decreased from 2014-2015 to 2016-2017 with the exception of TDF/FTC+DTG. Differences in the choice of the initial ART regimen were observed by hospitals' location. CONCLUSIONS: The choice of initial ART regimens is consistent with Spanish guidelines' recommendations, but is also clearly influenced by physician's perception based on patient's clinical and sociodemographic variables and by the prescribing hospital location

Spatiotemporal Characteristics of the Largest HIV-1 CRF02_AG Outbreak in Spain: Evidence for Onward Transmissions

Background and Aim: The circulating recombinant form 02_AG (CRF02_AG) is the predominant clade among the human immunodeficiency virus type-1 (HIV-1) non-Bs with a prevalence of 5.97% (95% Confidence Interval-CI: 5.41–6.57%) across Spain. Our aim was to estimate the levels of regional clustering for CRF02_AG and the spatiotemporal characteristics of the largest CRF02_AG subepidemic in Spain.Methods: We studied 396 CRF02_AG sequences obtained from HIV-1 diagnosed patients during 2000–2014 from 10 autonomous communities of Spain. Phylogenetic analysis was performed on the 391 CRF02_AG sequences along with all globally sampled CRF02_AG sequences (N = 3,302) as references. Phylodynamic and phylogeographic analysis was performed to the largest CRF02_AG monophyletic cluster by a Bayesian method in BEAST v1.8.0 and by reconstructing ancestral states using the criterion of parsimony in Mesquite v3.4, respectively.Results: The HIV-1 CRF02_AG prevalence differed across Spanish autonomous communities we sampled from (p &lt; 0.001). Phylogenetic analysis revealed that 52.7% of the CRF02_AG sequences formed 56 monophyletic clusters, with a range of 2–79 sequences. The CRF02_AG regional dispersal differed across Spain (p = 0.003), as suggested by monophyletic clustering. For the largest monophyletic cluster (subepidemic) (N = 79), 49.4% of the clustered sequences originated from Madrid, while most sequences (51.9%) had been obtained from men having sex with men (MSM). Molecular clock analysis suggested that the origin (tMRCA) of the CRF02_AG subepidemic was in 2002 (median estimate; 95% Highest Posterior Density-HPD interval: 1999–2004). Additionally, we found significant clustering within the CRF02_AG subepidemic according to the ethnic origin.Conclusion: CRF02_AG has been introduced as a result of multiple introductions in Spain, following regional dispersal in several cases. We showed that CRF02_AG transmissions were mostly due to regional dispersal in Spain. The hot-spot for the largest CRF02_AG regional subepidemic in Spain was in Madrid associated with MSM transmission risk group. The existence of subepidemics suggest that several spillovers occurred from Madrid to other areas. CRF02_AG sequences from Hispanics were clustered in a separate subclade suggesting no linkage between the local and Hispanic subepidemics

The use of a dual-task procedure for the assessment of cognitive effort associated with smoking urges

A dual-task procedure was used in two studies investigating Tiffany\u27s (1990) proposal that drug urges should operate at the cost of disrupting activities that demand nonautomatic processing. This theory assumes that urges represent the operation of capacity-limited, cognitive processes. Cigarette smokers imagined sentences containing urge or no-urge descriptors. During imagery, the subjects responded to a reaction time (RT) task while their heart rate (HR) and skin conductance levels (SCL) were monitored. The subjects also rated their smoking urge intensity and mood state associated with each of the urge and no-urge sentences. Relative to no-urge sentences, imagery of urge sentences increased urge and negative mood report, enhanced HR and SCL, and produced slower probe RTs. The overall pattern of results were inconsistent with classical conditioning theories of drug addiction, but supported Tiffany\u27s (1990) cognitive processing theory of urges. Moreover, it is suggested that dual-task, RT measures provide an innovative approach to the investigation of drug urges

Smoking expectancies in smokers and never smokers: an examination of the smoking Consequences Questionnaire Spanish

The factor structure of smoking expectancies was examined in daily smokers and never smokers. Participants completed the Smoking Consequences Questionnaire—Spanish (SCQ—Spanish; [Cepeda-Benito, A., & Reig-Ferrer, A. (2000). Smoking consequences questionnaire—Spanish. Psychology of Addictive Behaviors, 14, 219-230.]). Using confirmatory factor analysis (CFA), the eight-factor structure of the SCQ—Spanish was replicated in smokers only. Except for beliefs about negative-health outcome expectancies, daily smoking rate was strongly associated with all types of smoking outcome expectancies. In comparison to men, women smokers reported greater weight control and negative-affect reduction consequences from smoking. An exploratory factor analysis (EFA) suggested a four-factor structure for the scores of never smokers. The findings represent not only the first cross-validation of the SCQ—Spanish but they were also congruent with the notion that first-hand smoking experience is not necessary for the development of multifaceted smoking expectancies. Nonetheless, the finding of a more complex factors structure in smokers than in never smokers is in line with the hypothesis that drug-use expectancies become more complex with drug-use experience.This research was supported by two grants awarded to the authors, one from l'Oficina de Ciència i Tecnologia del Govern Valencià, (Ajuda per a estades d'investigadors convidats en Universitats i altres Centres d'investigació situats a la Comunitat Valenciana [ref: INV 01–35]) and one from the Ministerio de Educación, Cultura y Deporte de España (Ayudas para Estancias de Profesores, Investigadores, Doctores y Tecnólogos Extranjeros en España [ref: SB2000–0020])

Comparative efficacy of remotely delivered mindfulness-based eating awareness training versus behavioral-weight loss counseling during COVID-19

IntroductionDysregulated eating (emotional eating, cue-elicited eating, and dietary restraint and restriction) has been linked to being overweight or obese. The present investigation used a random controlled trial (RCT) to test the differential efficacy of remotely delivered Mindfulness-Based Eating Awareness Training (MB-EAT) and Behavioral Weight Loss (BWL) counseling.MethodsThe sample was recruited through advertisements that offered help to people “with problems controlling their eating” or “interested in improving their relationship with food” (n = 135).ResultsRetention was low in both groups (42%), but not dissimilar to retention rates reported in related clinical trials delivered “in person.” Among the participants who completed treatment, we found no between-group differences in any of the treatment outcomes, but participants in both groups experienced significant increases in eating-related mindfulness [Mindful Eating Questionnaire (MEQ) and awareness [Multidimensional Assessment of Interoceptive Awareness (MAIA), and significant decreases in unhealthy eating patterns [Dutch Eating Behavior Questionnaire (DEBQ); Binge Eating Scale (BES), and weight over the course of treatment. Participants in both groups also experienced increases in self-reported depression and anxiety symptoms [Hospital Anxiety and Depression Scale (HADS)], although these increases likely reflected normative changes observed in the population at large during COVID-19.DiscussionOverall, the results suggest that dysregulated eating and weight loss intervention delivered remotely via teleconference can be effective

Negative Affect Heightens Opiate Withdrawal-Induced Hyperalgesia in Heroin Dependent Individuals

This study examined the effect of emotion on opiate withdrawal induced hyperalgesia to determine whether emotional states modulate the magnitude of hyperalgesia. One hundred Hispanic men were recruited into one of three groups: heroin withdrawal, long-term heroin abstinence, and control. Participants were presented with pictures to induce neutral, positive, and negative emotional states. Affective valence, arousal, pain threshold, and tolerance to ischemic pain were measured. When pain threshold and tolerance were compared, the withdrawal group displayed significant heightened pain sensitivity when negative affect was induced. The authors also found that former heroin addicts showed heightened pain sensitivity following months of abstinence
