Moderating or mediating effects of family characteristics on socioeconomic inequalities in child health in high-income countries - a scoping review.

BACKGROUND: By explaining the development of health inequalities, eco-social theories highlight the importance of social environments that children are embedded in. The most important environment during early childhood is the family, as it profoundly influences children's health through various characteristics. These include family processes, family structure/size, and living conditions, and are closely linked to the socioeconomic position (SEP) of the family. Although it is known that the SEP contributes to health inequalities in early childhood, the effects of family characteristics on health inequalities remain unclear. The objective of this scoping review is to synthesise existing research on the mediating and moderating effects of family characteristics on socioeconomic health inequalities (HI) during early childhood in high-income countries. METHODS: This review followed the methodology of "Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews". To identify German and English scientific peer-reviewed literature published from January 1st, 2000, to December 19th, 2019, the following search term blocks were linked with the logical operator "AND": (1) family structure/size, processes, living conditions, (2) inequalities, disparities, diversities, (3) income, education, occupation, (4) health and (5) young children. The search covered the electronic databases PubMed, PsycINFO, and Scopus. RESULTS: The search yielded 7,089 records. After title/abstract and full-text screening, only ten peer-reviewed articles were included in the synthesis, which analysed the effects of family characteristics on HI in early childhood. Family processes (i.e., rules /descriptive norms, stress, parental screen time, parent-child conflicts) are identified to have mediating or moderating effects. While families' living conditions (i.e., TVs in children's bedrooms) are suggested as mediating factors, family structure/size (i.e., single parenthood, number of children in the household) appear to moderate health inequalities. CONCLUSION: Family characteristics contribute to health inequalities in early childhood. The results provide overall support of models of family stress and family investment. However, knowledge gaps remain regarding the role of family health literacy, regarding a wide range of children's health outcomes (e.g., oral health, inflammation parameters, weight, and height), and the development of health inequalities over the life course starting at birth.

Engagement in Health Risk Behaviours before and during the COVID-19 Pandemic in German University Students: Results of a Cross-Sectional Study.

Tobacco and cannabis use, alcohol consumption and inactivity are health risk behaviors (HRB) of crucial importance for health and wellbeing. The impact of the COVID-19 pandemic on university students' engagement in HRB has yet received limited attention. We investigated whether HRB changed during the COVID-19 pandemic, assessed factors associated with change and profiles of HRB changes in university students. A web-based survey was conducted in May 2020, including 5021 students of four German universities (69% female, the mean age of 24.4 years (SD = 5.1)). Sixty-one percent of students reported consuming alcohol, 45.8% binge drinking, 44% inactivity, 19.4% smoking and 10.8% cannabis use. While smoking and cannabis use remained unchanged during the COVID-19 pandemic, 24.4% reported a decrease in binge drinking while 5.4% reported an increase. Changes to physical activity were most frequently reported, with 30.6% reporting an increase and 19.3% reporting a decrease in vigorous physical activity. Being female, younger age, being bored, not having a trusted person and depressive symptoms were factors associated with a change in HRB. Five substance use behavior profiles were identified, which also remained fairly unchanged. Efforts to promote student health and wellbeing continue to be required, also in times of the COVID-19 pandemic.

Seroprevalence Brazil.

This chapter presents an overview of the seroprevalence of toxocariasis in Brazil and discusses how this zoonosis is studied, diagnosed, and treated in the Brazilian population. Toxocariasis in humans has a high prevalence in several regions of Brazil; however, this disease is neglected because of lack of knowledge, non-specific clinical signs, and difficult diagnosis. Most studies conducted in Brazil have estimated the prevalence of toxocariasis, i.e., the number of people who presented the disease at any given time. However, a few studies have determined disease incidence (number of new cases in a population at risk) and identified risk factors for Toxocara canis infection. Despite the high seroprevalence, the Brazilian population is not well aware of toxocariasis. Thus, the need of the hour is to raise awareness about this parasitic infection because of its worldwide distribution and potential health risk.

Asthma and Seroconversion from Toxocara spp. Infection: Which Comes First?

The aim of this study was to estimate the incidence of seroconversion of Toxocara spp. infection and related variables. We conducted a cohort study of 77 children aged 2-12 years who had negative serology in a previous cross-sectional study. Univariate and bivariate analyses were performed to describe the cohort, using socioeconomic, behavioral, and health conditions as variables. Logistic regression analysis was performed using seroconversion as the dependent variable, and the remaining variables are treated as independent variables. Asthma was the only independent variable that showed an association with seroconversion, with an odds ratio = 3.57 (1.01-12.6). The incidence of seroconversion from Toxocara spp. infection in the children followed was 10.4 per 100 per year. Previous studies reporting an association of asthma with toxocariasis have only been carried out using cross-sectional studies. Therefore, this study is one of only a few describing the incidence of seroconversion from Toxocara spp. infection, which is relevant for understanding the burden of this parasite.

A Systematic Review of Toxocariasis: A Neglected But High-Prevalence Disease in Brazil.

Toxocariasis is an anthropozoonosis that occurs in all parts of the world. In particular, this disease can often be found in developing countries and in regions, where basic sanitation conditions are poor. However, industrialized countries have reported seroprevalence rates as high as 14.2% in humans. The definitive hosts of the disease are dogs and cats, whereas humans are a paratenic host. To determine the burden of toxocariasis in Brazil, we followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to conduct a systematic review of the literature. Using keywords and applying the established criteria, we identified 160 publications and selected 22 articles for further analysis. The seroprevalence of toxocariasis in various regions of the country ranged from 4.2% to 65.4%. The highest prevalence was found in the northeast region, although the majority of the studies identified were from the southeast region. The findings suggest the importance of raising awareness among health professionals and public authorities about the fact that toxocariasis is a health problem.

Toxocaríase, asma e índice de massa corporal em crianças e adolescentes em Campinas-SP, 1996 a 1998 / Toxocariasis, asthma and body mass index in children and adolescent in Campinas, São Paulo State, Brazil, 1996-1998

OBJETIVO: analisar a associação entre diagnóstico de asma e índice de massa corporal (IMC) em crianças e adolescentes com e sem marcador sorológico para toxocaríase. MÉTODOS: estudo transversal, com dados dos prontuários de indivíduos de 2 a 14 anos de idade avaliados quanto à infecção por toxocaríase na unidade básica de saúde do Jardim Santa Mônica, Município de Campinas-SP, Brasil, tendo por referência o período de 1996 a 1998; para o estudo das associações entre presença de toxocaríase, asma e IMC, utilizou-se o teste de Wilcoxon. RESULTADOS: entre 116 participantes, 37,9 por cento tinham asma e 54,3 por cento tinham toxocaríase; aqueles com asma e toxocaríase apresentaram maiores escores z para a distribuição do IMC (p=0,04); nos indivíduos com asma e sem toxocaríase, não se encontrou essa associação (p=0,17). CONCLUSÃO: houve associação entre asma e aumento do IMC em crianças e adolescentes com toxocaríase, o que não foi observado nos indivíduos sem a parasitose.

OBJECTIVE: to analyze the association between asthma diagnosis and body mass index (BMI) in children and adolescents with and without sorological markers of toxocariasis. METHODS: this is a cross-sectional study based on the review of medical records of individuals aged 2-14 years of age, covering the period 1996-1998 and assessed for toxocariasis infection at the Jardim Santa Monica Primary Health Unit in Campinas-SP. Wilcoxon's test was used to study associations between the presence of toxocariasis, asthma and BMI. RESULTS: out of 116 eligible records, 37.9 per cent had asthma and 54.3 per cent had toxocariasis. Those having both asthma and toxocariasis had higher z scores for EMI distribution (p = 0.04). Association was not found in those having asthma but not toxocariasis (p = 0.17). CONCLUSION: association was found between asthma and increased BMI in children and adolescents with toxocariasis, but not in those who did not have toxocariasis.
