Review question: Which family characteristics mediate or moderate the association between the family’s socioeconomic position and health in school-aged children and adolescents in countries with developed economies?
Einleitung Die gesundheitlichen Folgen von Adipositas für junge Menschen können schwerwiegend sein. Bei der Entwicklung verschiedener Gesundheitsoutcomes wie Adipositas spielt für junge Menschen die Familie als auch ihre sozioökonomische Position (SEP) eine große Rolle. In dieser Analyse wird untersucht, welche familiäre Determinanten den Zusammenhang zwischen SEP der Familie und Adipositas bei Jugendlichen erklären.
Methoden Die vorliegende Analyse wurde mit Daten der "Studie zur Gesundheit von Kindern und Jugendlichen in Deutschland" (KiGGS) (Basiserhebung, Welle 1 und 2) durchgeführt (1301 weibliche und 1232 männliche 11- bis 17-Jährige). Mittels logistischer Regressionsmodelle (KHB-Methode) wurden für den Zusammenhang zwischen der SEP der Familie (Einkommen, berufliche Stellung, Bildung, SES-Index) und Adipositas (Ja/Nein) bei Jugendlichen die mediierenden Effekte von familiären Determinanten (elterliches Rauchen, elterliche sportliche Aktivitäten, elterliches Übergewicht, familiärer Stress und familiärer Zusammenhalt) analysiert.
Ergebnisse Die Prävalenz von Adipositas betrug 7,9 % bei den weiblichen und 8,4 % bei den männlichen Jugendlichen. Es zeigen sich signifikante Zusammenhänge zwischen Adipositas und SEP zu Ungunsten von jenen mit niedriger sozioökonomischer Position. Familiäre Determinanten erklären teilweise oder vollständig den Zusammenhang zwischen SEP und Adipositas bei Jugendlichen. Es wurden geschlechtsspezifische Unterschiede im Ausmaß der Mediation der Familie gefunden. Bei Jungen erklären familiäre Determinanten vollständig den Zusammenhang zwischen Adipositas und Einkommen sowie zwischen Adipositas und der beruflichen Stellung der Eltern. Bei männlichen Jugendlichen lässt sich der indirekte Effekt abhängig von der jeweiligen SEP-Variable zu 20,8 – 27,9 % auf das elterliche Rauchen, zu 14,8 – 26,3 % auf die elterliche sportliche Aktivität und zu 42,6 – 63,6 % auf das elterliche Übergewicht zurückführen. Bei Mädchen wurde der Zusammenhang zwischen der SEP und Adipositas teilweise durch familiäre Determinanten erklärt. Bei weiblichen Jugendlichen lässt sich der indirekte Effekt abhängig von der jeweiligen SEP-Variable zu 26,0 – 52,2 % auf das elterliche Rauchen und zu 41,6 – 67,6 % auf das elterliche Übergewicht zurückführen.
Schlussfolgerung Die Adipositas-Prävalenz von Jugendlichen variiert nach dem SEP. Familiäre Determinanten sind wichtige mediierende Faktoren für gesundheitliche Ungleichheiten bei Adipositas von Jugendlichen. Es zeigt sich, dass sich Unterschiede in der Adipositas nach SEP insbesondere durch das elterliche Gesundheitsverhalten (v.a. elterliches Rauchen, elterliches Übergewicht und elterliche sportliche Aktivität) erklären lassen. Die Berücksichtigung und Einbindung der Familie bei der Planung und Umsetzung von Gesundheitsförderungs- und Präventionsprogrammen für gesundheitliche Chancengleichheit bei Jugendlichen ist essentiell.
Children’s overweight is strongly associated with family socioeconomic position (SEP) and family characteristics (FC). There is limited research on the extent to which FC account for a socioeconomic gradient in childhood overweight. This study examined whether FC explain SEP differences in the prevalence of overweight. The study used baseline data of preschool-aged children from the German ‘PReschool INtervention Study’. The sample (n = 872, 48% girls) was recruited at kindergartens in Baden-Württemberg, Germany. Data included children’s measured weight status and parents’ reports on socioeconomic indicators (e.g., school education, vocational education, income) and FC. Variables represent main determinants of overweight (nutrition: sweets consumption in front of TV, soft drink consumption, regular breakfast, child sets table; physical activity: outdoor sports; parental role model). In single mediation analyses indirect effects of SEP on overweight were analysed (OR[95%CI]). Preschool girls and boys with low parental education had higher odds for overweight than children with high parental education. Among boys, low levels of parental education contributed to the odds of overweight via indirect effects by both factors ‘sweets consumption in front of TV’ (OR = 1.31[1.05–1.59]) and ‘no sports’ (OR = 1.14[1.01–1.38]). Among girls, FC measured did not explain SEP differences in overweight. Family nutrition and parental/family physical activity contribute to inequalities in overweight among preschool boys, but not girls. Research is needed to identify FC that explain inequalities in overweight for both.
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.
Background: Although early childhood is a life period of overall good health, research shows that families’ socioeconomic position (SEP) is affecting children’s health from pregnancy on, ultimately leading to health inequalities. Little is currently known about the pathways by which family SEP is influencing child health and health-related behaviour, and which role family characteristics play. The scoping review therefore aims to screen the international literature on the mediating and moderating effects of contextual and compositional family characteristics on socioeconomic health risks of pre-school children in developed countries.
Methods: Following the PRISMA guidelines for scoping reviews, three online databases (Pubmed, PsycINFO, and Scopus) will be searched for literature in English or German published after year 2000. The two-step data screening approach and the subsequent data extraction will be conducted independently by two researchers in consideration of specific criteria and a previously tested standardized data extraction form. Due to the broad research question at hand, various study designs (e.g. cross-sectional, intervention, cohort studies, and qualitative studies), SEP measures (e.g. education, income) and compositional (e.g. family size, migration) or contextual (e.g. parenting, housing) family characteristics influencing children ́s health will be included. Since diverse definitions and reporting formats of subjective health, health behaviour, well-being, and diseases will be considered, a substantial heterogeneity in outcome measures focusing on the age group of 0-6 years is expected. Thus, a narrative synthesis of the findings will be performed according to the Centre for
Reviews and Dissemination framework.
Ethics and dissemination: Because no primary data will be collected, ethical clearance will not be required. Dissemination will include peer-reviewed publications and conferences.
Socioeconomic position and self-rated health among adolescents: the mediating role of the family
(2022)
Background
Although health inequalities in adolescence are well documented, the underlying mechanisms remain unclear. Few studies have examined the role of the family in explaining adolescents’ health inequalities. The study aimed to explore whether the association between socioeconomic position and self-rated health (SRH) was mediated by familial determinants.
Methods
Using data from wave 2 of the KiGGS study (1,838 female and 1,718 male 11- to 17-year-olds), linear regression analyses were conducted to decompose the total effects of parents’ education, occupation, income, socioeconomic position index, and adolescents’ subjective social status on SRH into direct effects and indirect effects through familial determinants (family cohesion, parenting styles, parental well-being, stress, obesity, smoking and sporting activity).
Results
A significant total effect of all socioeconomic position indicators on SRH was found, except for income in male adolescents. In female adolescents, more than 70% of the total effects of each socioeconomic position indicator were explained by familial mediators, whereas no significant direct effects remained. The most important mediator was parental well-being, followed by family cohesion, parental smoking and sporting activity. In male adolescents, the associations of parental education, the socioeconomic position index and subjective social status with SRH were also mediated by familial determinants (family cohesion, parental smoking and obesity). However, a significant direct effect of subjective social status remained.
Conclusions
The family appears to play an important role in explaining health inequalities, particularly in female adolescents. Reducing health inequalities in adolescence requires policy interventions, community-based strategies, as well as programs to improve parenting and family functioning.
Objective
Although health inequalities in adolescence are well documented, the underlying mechanisms remain unclear. Few studies have examined the role of the family in explaining the association between the family’s socioeconomic position and adolescents’ self-rated health. The current study aimed to explore whether the association between socioeconomic position and self-rated health was mediated by familial determinants.
Methods
Using data from wave 2 of the”German Health Interview and Examination Survey for Children and Adolescents” (KiGGS) (1,838 female and 1,718 male 11- to 17-year-olds), linear regression analyses were conducted to decompose the total effects of income, education, occupational status, socioeconomic position index and adolescents’ subjective social status on self-rated health into direct effects and indirect effects through familial determinants (family cohesion, parental well-being, parental stress, parenting styles, parental obesity, smoking and sporting activity).
Results
A significant total effect of all socioeconomic position indicators on self-rated health was found, except for income in male adolescents. In female adolescents, more than 70% of the total effects of each socioeconomic position indicator were explained by familial mediators, whereas no significant direct effects remained. The most important mediator was parental well-being, followed by family cohesion, parental smoking and sporting activity. In male adolescents, the associations between income, parental education, the socioeconomic position index and subjective social status were also mediated by familial determinants (family cohesion, parental smoking, obesity and living in a single-mother family). However, a significant direct effect of subjective social status remained.
Conclusion
The analysis revealed how a family’s position of socioeconomic disadvantage can lead to poorer health in adolescents through different family practices. The family appears to play an important role in explaining health inequalities, particularly in female adolescents. Reducing health inequalities in adolescence requires policy interventions (macro-level), community-based strategies (meso-level) and programs to improve parenting and family functioning (micro-level).
Do families have moderating or mediating effects on early health inequalities? A scoping review
(2021)
Background
During early childhood, families have a crucial impact on children's health behaviour, health, and development (bhd). However, a family's socioeconomic position (SEP) determines both the parental behaviour, living conditions, and child health. To understand how family characteristics may influence the development of health inequalities, this scoping review synthesised research on their mediating and moderating effects.
Methods
The review followed the guidelines of the PRISMA Extension for Scoping Reviews. The search included German and English peer-reviewed articles published between January 1st, 2000 and December 19th, 2019. The search in PubMed, PsycINFO, and Scopus used both free text terms in the title/abstract and index terms within linked keyword blocks: (1) family characteristics, (2) inequalities, (3) income, education, occupation, (4) bhd, (5) newborn, infant, toddler, preschooler. Two researchers independently examined eligibility for inclusion in two rounds (title/abstract; full-text).
Results
Of 7,089 articles identified, ten sources were included that studied family characteristics and health inequalities among 0-6 years olds. Parental rules, stress, and screentime, and TV in bedroom showed mediating effects on inequalities in behaviour problems or children's screentime. Families' negativity, single parenthood, and the number of children in the household moderated differences in impairment, health, behaviour problems, development or breastfeeding initiation.
Conclusions
The effect of family characteristics on early health inequalities has been sparsely investigated. The evidence supported models of family stress and investment. Further research is needed to comprehensively understand this association.
Key messages
Family characteristics contribute to health inequalities.
Taking families’ stress and investment into account could improve targeted prevention efforts aimed at reducing health inequalities.
This scoping review systematically mapped evidence of the mediating and moderating effects of family characteristics on health inequalities in school-aged children and adolescents (6–18 years) in countries with developed economies in Europe and North America. We conducted a systematic scoping review following the PRISMA extension for Scoping Reviews recommendations. We searched the PubMed, PsycINFO and Scopus databases. Two reviewers independently screened titles, abstracts and full texts. Evidence was synthesized narratively. Of the 12,403 records initially identified, 50 articles were included in the synthesis. The included studies were conducted in the United States (n = 27), Europe (n = 18), Canada (n = 3), or in multiple countries combined (n = 2). We found that mental health was the most frequently assessed health outcome. The included studies reported that different family characteristics mediated or moderated health inequalities. Parental mental health, parenting practices, and parent-child-relationships were most frequently examined, and were found to be important mediating or moderating factors. In addition, family conflict and distress were relevant family characteristics. Future research should integrate additional health outcomes besides mental health, and attempt to integrate the complexity of families. The family characteristics identified in this review represent potential starting points for reducing health inequalities in childhood and adolescence.
