Background:Studies suggest that lutein and zeaxanthin may be important for cognitive development in children, but a comprehensive evidence synthesis is lacking. The purpose of this evidence synthesis was to analyse the available data regarding the role of lutein and zeaxanthin for cognition in children and propose a theoretical basis for future studies.Methods:The PubMed, Scopus, the ISRCTN registry and Cochrane Library databases were searched for studies that evaluated the relationship between lutein and zeaxanthin and cognitive function in children. Reference list and ancestry searches were performed on relevant articles. A total of 543 articles were identified, of which six cross-sectional studies were included.Results:The literature search revealed that the evidence concerning the effect of lutein and zeaxanthin on cognition in children is sparse. However, there is some preliminary evidence indicating a positive association between lutein and zeaxanthin and cognition in childhood.Conclusions:The cross-sectional nature of the few studies available and the lack of RCT data indicates a need for further investigation before any firm conclusions can be drawn.

Status anxiety, the constant concern about individuals’ position on the social ladder, negatively affects social cohesion, health, and wellbeing (e.g., chronic stress). Given previous findings showing that status anxiety is associated with economic inequality, we aimed in this research to test this association experimentally. A cross-sectional study (Study 1) was run in order to discard confounding effects of the relationship between perceived economic inequality (PEI) and status anxiety, and to explore the mediating role of a competitive climate (N = 297). Then we predicted that people assigned to a condition of high inequality would perceive more status anxiety in their social context, and they would themselves report higher status anxiety. Thus, in an experimental study (Study 2) PEI was manipulated (N = 200). In Study 1, PEI uniquely predicted status anxiety, and perceived competitiveness mediated the relationship. In Study 2 PEI increased perceived contextual status anxiety, a specific form of perceived competitiveness based on socioeconomic status (SES). Moreover, preliminary evidence of an indirect effect was found from PEI to personal status anxiety, through (higher) perceived contextual status anxiety. These preliminary findings provide experimental evidence for the effects of economic inequality on status anxiety and the mechanism involved. Economic inequality makes people feel that they live in a society where they are constantly concerned and competing with each other for their SES. These results could have important implications as health and wellbeing could be promoted by reducing economic inequalities and the competitive and materialistic environments of our societies.

Abstract Background Cardiorespiratory fitness (CRF) and pubertal stages have been related to many health outcomes, including obesity and adipocytokines. Thus, the present study aimed to analyze the moderator role of CRF and pubertal stage in the relationship between adiposity and adipocytokines in girls. Method This cross-sectional study was performed with 42 pre-pubertal girls aged from 7 to 11 years and 54 post-pubertal girls aged from 13 to 17 years. Blood samples were collected to determine the serum levels of leptin and adiponectin, and then the leptin/adiponectin ratio (L/A ratio) was calculated. CRF, anthropometric and body composition indicators were assessed. For statistical analysis, descriptive statistics and several linear regression models were used. The moderation analysis was tested using the PROCESS macro. Results An interaction between body mass index (BMI) and CRF (β: –0.70; confidence interval [CI]: –1.29, –0.12), as well as between BMI and pubertal stage (β: 0.79; CI: 0.28, 1.30) with leptin, was found. Regarding the L/A ratio, an interaction was found only in BMI × CRF (β: –0.56; CI: –1.06, –0.06). Using a combined interaction (CRF and pubertal stage), the results showed a positive association between BMI with leptin and L/A ratio only in low CRF, pre-pubertal and post-pubertal stages. Conclusion This study suggests a protective role of high levels of CRF in the relationship between BMI and adipocytokines. Despite the effect of pubertal stage, the results suggest that youth should be engaged in physical activity in order to improve CRF levels and consequently improve cardiometabolic health.

AbstractExisting reviews suggest that milk and other dairy products do not play a role in the development of obesity in childhood, but they do make an important contribution to children’s nutrient intake. It is thus curious that public health advice on the consumption of dairy products for children is often perceived as unclear. The present review aimed to provide an overview of the totality of the evidence on the association between milk and other dairy products, and obesity and indicators of adiposity, in children. Our search identified forty-three cross-sectional studies, thirty-one longitudinal cohort studies and twenty randomised controlled trials. We found that milk and other dairy products are consistently found to be not associated, or inversely associated, with obesity and indicators of adiposity in children. Adjustment for energy intake tended to change inverse associations to neutral. Also, we found little evidence to suggest that the relationship varied by type of milk or dairy product, or age of the children, although there was a dearth of evidence for young children. Only nine of the ninety-four studies found a positive association between milk and other dairy products and body fatness. There may be some plausible mechanisms underlying the effect of milk and other dairy products on adiposity that influence energy and fat balance, possibly through fat absorption, appetite or metabolic activity of gut microbiota. In conclusion, there is little evidence to support a concern to limit the consumption of milk and other dairy products for children on the grounds that they may promote obesity.

The aim of the present study was to determine whether normal sleepers with vulnerability to insomnia, via high sleep reactivity, demonstrate more sleep-related dysfunctional cognitions and behaviours and poorer psychological health compared to those who are not vulnerable. Further, the influence of stress on the relationship between sleep reactivity and psychological health was also examined. A cross-sectional survey of 737 young adult ‘normal’ sleepers from the general population was undertaken. Results indicated normal sleepers vulnerable to insomnia demonstrated more sleep-related dysfunctional cognitions and behaviours as well as poorer psychological health compared to those not vulnerable. Furthermore, the relationship between sleep reactivity and psychological health was moderated by perceived stress over the previous month and life events over the previous year. Therefore, identifying and supporting those who are vulnerable to insomnia may be a fruitful avenue for preventative public health campaign to mitigate both insomnia and poor psychological health.

Most previous research has examined the relationship between FB addiction and burnout level by conducting cross-sectional studies. Little is known about the impact of changes in burnout on FB addiction in an educational context. Through a two-way longitudinal survey of a student population sample (N = 115), this study examined the influence of changes in academic burnout over time and FB motives and importance (measured at the beginning and the end of the semester) on FB intrusion measured at the end of the academic semester. The findings show that: (1) increases in cynicism and in FB motives and importance significantly predicted time2 FB intrusion; (2) FB importance enhanced the prediction power of changes in the academic burnout total score, exhaustion and personal inefficacy, and reduced the regression coefficient of changes in cynicism; (3) the interaction effects between FB social motive use and changes in academic burnout, as well as between FB importance and personal inefficacy and exhaustion, accounted for a significant change in the explained variance of time2 FB intrusion. About 20–30% of the variance in time2 FB intrusion was explained by all the examined variables and by the interactions between them. The results suggest that changes in academic burnout and FB motives and importance are suppressive variables, as including these variables in the regression model all together changed the significance of the relationship between independent variables and FB intrusion.

The worldwide prevalence of obesity has dramatically increased, mostly in children and adolescents. The Emotional Eating theoretical model has proposed that the failure in emotional regulation could represent a risk factor for establishing maladaptive overeating behavior that represents an inadequate response to negative emotions and allows increasing body-weight. This systematic review investigates the relationship between overeating and both emotional regulation and emotional intelligence in childhood and adolescence, considering both cross-sectional and longitudinal studies. Moreover, another goal of the review is evaluating whether emotional regulation and emotional intelligence can cause overeating behaviors. The systematic search was conducted according to the PRISMA-statement in the databases Medline, PsychArtcles, PsychInfo, PubMed, Scopus, and Web of Sciences, and allows 484 records to be extracted. Twenty-six studies were selected according to inclusion (e.g., studies focused on children and adolescents without clinical conditions; groups of participants overweight or with obesity) and exclusion (e.g., studies that adopted qualitative assessment or cognitive-affective tasks to measure emotional variables; reviews, commentary, or brief reports) criteria detailed in the methods. Cross-sectional studies showed a negative association between emotional regulation and overeating behavior that was confirmed by longitudinal studies. These findings highlighted the role of maladaptive emotion regulation on overeating and being overweight. The relationship between these constructs in children and adolescents was consistent. The results indicated the complexity of this association, which would be influenced by many physiological, psychological, and social factors. These findings underline the need for further studies focused on emotion regulation in the development of overeating. They should analyze the mediation role of other variables (e.g., attachment style, peer pressure) and identify interventions to prevent and reduce worldwide overweight prevalence.

Previous studies have found some risk factors of cyberbullying. However, little is known about how mother phubbing may influence adolescent cyberbullying, and the mediating and moderating mechanisms underlying this relationship. “Phubbing,” which is a portmanteau of “phone” and “subbing,” refers to snubbing other people and focus on smartphones in social interactions. This study examined whether mother phubbing, which refers to being phubbed by one’s mother, would be positively related to adolescent cyberbullying, whether perceived mother acceptance would mediate the relationship between mother phubbing and adolescent cyberbullying, and whether emotional stability would moderate the pathways between mother phubbing and adolescent cyberbullying. The sample consisted of 4,213 Chinese senior high school students (mean age 16.41 years, SD = 0.77, 53% were female). Participants completed measurements regarding mother phubbing, cyberbullying, perceived mother acceptance, and emotional stability. The results indicated that mother phubbing was positively related to cyberbullying, which was mediated by perceived mother acceptance. Further, moderated mediation analyses showed that emotional stability moderated the direct path between mother phubbing and cyberbullying and the indirect path between mother phubbing and perceived mother acceptance. This study highlighted the harmful impact of mother phubbing on adolescents by showing a positive association between mother phubbing and adolescent cyberbullying, as well as the underlying mechanisms between mother phubbing and adolescent cyberbullying.

The relationship between serum dehydroepiandrosterone sulphate (DHEA-S) and anti-Mullerian hormone (AMH) levels has not been fully established. Therefore, we performed a large-scale cross-sectional study to investigate the association between serum DHEA-S and AMH levels. The study included a total of 2155 infertile women aged 20 to 46 years who were divided into four quartile groups (Q1 to Q4) based on serum DHEA-S levels. We found that there was a weak positive association between serum DHEA-S and AMH levels in infertile women (r = 0.190, p < 0.001). After adjusting for potential confounders, serum DHEA-S levels positively correlated with serum AMH levels in infertile women (β = 0.103, p < 0.001). Infertile women in the highest DHEA-S quartile category (Q4) showed significantly higher serum AMH levels (p < 0.001) compared with women in the lowest DHEA-S quartile category (Q1). The serum AMH levels significantly increased across increasing DHEA-S quartile categories in infertile women (p = 0.014) using generalized linear models after adjustment for potential confounders. Our data show that serum DHEA-S levels are positively associated with serum AMH levels.
