Anxiety sensitivity as a mediator of the association between asthma and smoking

Objective: Despite its negative effects, smoking is more common among individuals with asthma compared to those without. Anxiety sensitivity (fear of arousal-related sensations) is associated with both smoking and asthma; however, no research, to date, has examined the interplay between these three factors. Thus, the purpose of the current study was to evaluate the mediating role of anxiety sensitivity in the association between asthma diagnosis and smoking status. Methods: The current study was a secondary analysis of data from three existing datasets of non-smokers and smokers with and without asthma (n?=?433; 56.3% female, M_age?=?34.01 years, SD?=?13.9). Participants provided information on their asthma diagnosis status and smoking status and completed self-report measures. Results: As hypothesized, after controlling for gender, race and age, there was a significant indirect effect of asthma diagnosis on smoking status through anxiety sensitivity (95% CI?=?0.07–0.48). Conclusions: These results indicate that the association between asthma diagnosis and smoking status appears to be driven, in part, by anxiety sensitivity and suggest that anxiety sensitivity may serve as an important target for prevention and intervention efforts for smokers with asthma.

Is a friend truly a treasure? Evolution of friendship competence from pre-school up to the last year of primary school

A Friend is truly a treasure, in accordance with age and competence’s qualitative changes. The aim of this study was to con?rm the increase in friendship competence and its multifactorial nature in 3- up to 10-year-old children, and to verify gender differences, and parenting in?uences on the concept of friendship. A semi-structured interview was administered in a natural context to 3- to 10-year-old children (N?=?167; Mean?=?7.6 years; SD?=?2.16). According to Selman’s Model, the coding provides ?ve sub-categories: (1) friendship; (2) social perspective taking; (3) emotions understanding; (4) social interaction strategies; and (5) aggressiveness. Three parental style questionnaires were administered to parents. Results point up an increase in social skills according to age. The Friendship Interview turned out to be a reliable tool able to investigate how the concept of friendship is also structured in preschool children.     

Debate: COVID-19 and psychological well-being of children and adolescents in Italy

Italy was the first country in Europe to deal with COVID-19. Measures taken by the government to contain the spread of the virus were based mainly on quarantine and social distancing, with dramatic economic, social and psychological consequences. Since March, Italian children and adolescents are facing school closures, which have caused a disruption in the daily lives of millions of young people and their families. To date, despite the slow reopening, the government has decided to maintain school closures for the entire academic year, leaving the future of young people in uncertainty. There is already some evidence that quarantine and social isolation are having negative impact on children's and adolescents' psychological well-being. Moreover, this situation will mainly affect those children and adolescents with pre-existing vulnerabilities and those suffering of mental disorders. It is imperative to keep young people’s needs at the core of reconstruction plans, allowing them to return to school safely, and providing them with some strategies to heal and dealing with this stressful and potentially traumatic situation.

Pathways in the association between sugar sweetened beverages and child asthma traits in the 2nd year of life: Findings from the BRISA cohort

Studies on the exposure of children to sugar-sweetened beverages (SSBs) at an early age may contribute to better understand the common causes and the temporal order of the relationships between obesity and asthma in early childhood. The objective of this study was to estimate the association between SSB and child asthma traits in the 2nd year of life, modeling direct and indirect pathways mediated by the highest BMI-z of the child and allergic inflammation. Data from the BRISA cohort, São Luís-MA, Brazil (n = 1140), were obtained from the baseline and from the follow-up performed at the 2nd year of life. The main explanatory variable was the calories from added sugars in SSBs as a percentage of the total daily energy intake. The outcome child asthma traits was a latent variable deduced from four indicators: medical diagnosis of asthma, wheezing, emergency visit due to intense wheezing, and medical diagnosis of rhinitis. A high percentage of daily calories from sugars added to SSBs was directly associated with higher values of child asthma traits (standardized coefficient (SC = 0.073; P = .030)). High levels of eosinophils were also directly associated with child asthma traits (SC = 0.118; P = .049). No mediation pathways were observed via greater BMI-z or eosinophil counts. Therefore, early exposure of children to SSB may contribute to increased risk of childhood asthma, preceding the link between sugar consumption and overweight/obesity, not yet evident in children in the first 2 years of life.     

Using structural equation modelling to understand the contributors to anaemia among young Burkinabe children

Anaemia is a persistent problem among young Burkinabe children, yet population‐specific information on its determinants is scant. We used baseline data from an evaluation of Helen Keller International's Enhanced Homestead Food Production Program (n=1210 children) to quantify household‐, mother‐, and child‐level factors associated with anaemia in Burkinabe children aged 6‐12 months. We used structural equation modelling to assess a theoretical model, which tested four categories of factors: (a) household food security and dietary diversity, (b) household sanitation and hygiene (latrine and poultry access and bednet ownership), (c) maternal factors (anaemia, stress, cleanliness, and health, hygiene and feeding knowledge and practices), and (d) child nutrition and health (iron deficiency (ID), retinol binding protein (RBP), malaria, and inflammation). The model also included household socio‐economic status, size, and polygamy; maternal age and education; and child age and sex. Results showed that ID, malaria, and inflammation were the primary direct determinants of anaemia, contributing 15%, 10%, and 10%, respectively. Maternal knowledge directly explained improved child feeding practices and household bednet ownership. Household dietary diversity directly explained 18% of child feeding practices. Additionally, RBP, child age and sex, and maternal anaemia directly predicted child haemoglobin. Our findings suggest that program effectiveness could be increased by addressing the multiple, context‐specific contributors of child anaemia. For young Burkinabe children, anaemia control programs that include interventions to reduce ID, malaria, and inflammation should be tested. Other potential intervention entry points suggested by our model include improving maternal knowledge of optimal health, hygiene, and nutrition practices and household dietary diversity.
