Research on Environmental Influencing Factors of Overweight and Obesity in Children and Adolescents in China

This study aimed to explore the impact of environmental factors such as latitude, altitude, family socioeconomic status (SES), and level of urbanization on overweight and obesity (ow/ob) in children and adolescents. The participants comprised 26,120 children and adolescents aged 10–18 from 16 provinces in China. Differences in the prevalence of ow/ob under different environmental conditions were evaluated by the chi-square test. The influence of various environmental factors on ow/ob was obtained by logistic regression analysis. We found that (1) the prevalence of ow/ob fell between from 19.2% to 11.9% at 10 years old and from 13.8% to 6% at 18 years old; (2) latitude, family SES, income, and urbanization level are positively correlated with the prevalence of ow/ob; and (3) altitude has a negative correlation with the prevalence of ow/ob. The prevalence of ow/ob decreased with age in children and adolescents aged 10–18, and the risk of ow/ob showed significant differences in latitude, altitude, family SES level, gross domestic product (GDP), and level of urbanization.

Environmental Correlates of Adolescent’ Materialism: Interpersonal Role Models, Media Exposure, and Family Socio-economic Status

The present study examined how adolescents’ materialism relates to interpersonal materialism role models (i.e., mothers’, fathers’, siblings’, and peers’), media exposure, and family socio-economic status (SES). We obtained our data from the adolescent, his/her mother and father, and one each of his/her siblings and peers. The results showed that mother’s, father’s, sibling’s and peer’s’, materialism are approximately equally strong predictors of adolescents’ materialism. Further analyses, using structural equation modeling, revealed that interpersonal materialism role models and media exposure both positively predicted adolescents’ materialism; in contrast to past literature, family SES was also significantly positively related to adolescents’ materialism. Limitations and implications of the current project are discussed.

Exploring the Intersectionality of Family SES and Gender with Psychosocial, Behavioural and Environmental Determinants of Physical Activity in Dutch Adolescents: A Cross-Sectional Study

BackgroundExamining the determinants of adolescent’s physical activity (PA) and how they may differ according to the intersection of gender and family socioeconomic status (SES) can support the development of tailored interventions to more effectively promote adolescents’ PA. This study explored how the influence of psychosocial, behavioural and environmental determinants on adolescent’s PA differed according to gender and family SES. MethodsThis study used data from the Dutch survey Health Monitor Youth 2015. Adolescents (n=9,068) aged 12-19 were included for the study. The associations between psychosocial, behavioural, and environmental determinants and PA (days per week engaging in at least one hour of PA) were examined with multilevel linear regression analysis. Potential interactions between these determinants, gender and family SES were explored.ResultsOn average, adolescents engaged in at least one hour of PA for 4,2 days per week. Poor self-perceived health, low peer social support, and a weak connection with the environment were all associated with lower PA in adolescents. Daily smoking, cannabis use, risk of problematic gaming and social media use, as well as lack of daily consumption of fruit, vegetables, water and breakfast were associated with lower PA, whereas binge drinking was not. Interactions revealed that poor self-perceived health was associated with lower PA in adolescents from moderate- and high-SES families, but not in low-SES adolescents, whereas cannabis use was only associated with lower PA amongst low-SES adolescents. Low peer social support was associated with lower PA across all groups, but it was most strongly associated with lower PA amongst male adolescents from low-SES families than in other subgroups. Amongst low-SES males, low peer social support was associated with a 1.47 reduction in days engaging in sufficient PA, compared with a 0.69 reduction for high-SES males.ConclusionsThis study identified several psychosocial, behavioural and environmental determinants that can be targeted to potentially increase adolescent’s PA. We also found that correlates of PA differed according to the intersection of gender and family SES. Our findings suggest that PA interventions should be tailored according to gender and SES to address the specific needs, barriers and facilitators of different subgroups.

Family SES Is Associated with the Gut Microbiome in Infants and Children

Background: While early life exposures such as mode of birth, breastfeeding, and antibiotic use are established regulators of microbiome composition in early childhood, recent research suggests that the social environment may also exert influence. Two recent studies in adults demonstrated associations between socioeconomic factors and microbiome composition. This study expands on this prior work by examining the association between family socioeconomic status (SES) and host genetics with microbiome composition in infants and children. Methods: Family SES was used to predict a latent variable representing six genera abundances generated from whole-genome shotgun sequencing. A polygenic score derived from a microbiome genome-wide association study was included to control for potential genetic associations. Associations between family SES and microbiome diversity were assessed. Results: Anaerostipes, Bacteroides, Eubacterium, Faecalibacterium, and Lachnospiraceae spp. significantly loaded onto a latent factor, which was significantly predicted by SES (p < 0.05) but not the polygenic score (p > 0.05). Our results indicate that SES did not predict alpha diversity but did predict beta diversity (p < 0.001). Conclusions: Our results demonstrate that modifiable environmental factors influence gut microbiome composition at an early age. These results are important as our understanding of gut microbiome influences on health continue to expand.

Family Socioeconomic Status, Parental Involvement, and Academic Achievement: The Moderating Role of Adolescents’ Subjective Social Mobility

The correlations between a low family socioeconomic status (SES) and adolescents’ poor academic outcomes have been widely documented. However, the mechanisms through which family SES is associated with adolescents’ academic achievement are not well understood. Therefore, this study examined the mediating roles of different types of parental involvement (i.e., parental school-based involvement, academic socialization, and home-based involvement) and the moderating role of adolescents’ subjective social mobility in the relationships between family SES and academic achievement by using multisource data. The valid sample consisted of 842 adolescents ([Formula: see text] = 12.28 years, 40.97% girls) who were recruited from five township public schools in China. The results indicated that all three types of parental involvement partially mediated the relationships between family SES and adolescents’ Chinese and math achievement; parental school-based involvement had the strongest mediating effects, followed by academic socialization, and home-based involvement had the lowest mediating effects. Moreover, the path from parental home-based involvement to Chinese achievement in the mediation model was moderated by the adolescents’ subjective social mobility. In conclusion, parental involvement is an important mediating mechanism through which a low family SES impedes adolescents’ academic achievement, and adolescents’ subjective social mobility can play a buffering role in the relationship between parental home-based involvement and Chinese achievement.

The relationship of socioeconomic status in childhood and adulthood with compassion: A study with a prospective 32-year follow-up

The objective of this study was to investigate (i) whether childhood family SES predicts offspring’s compassion between ages 20–50 years and (ii) whether adulthood SES predicts compassion or vice versa. We used the prospective population-based Young Finns data (N = 637–2300). Childhood family SES was evaluated in 1980; participants’ adulthood SES in 2001 and 2011; and compassion for others in 1997, 2001, and 2012. Compassion for others was evaluated with the Compassion scale of the Temperament and Character Inventory. The results showed that high childhood family SES (a composite score of educational level, occupational status, unemployment status, and level of income) predicted offspring’s higher compassion between ages 30–40 years but not in early adulthood or middle age. These results were obtained independently of a variety of potential confounders (disruptive behavior in childhood; parental mental disorder; frequency of parental alcohol use and alcohol intoxication). Moreover, high compassion for others in adulthood (a composite score of educational level, occupational status, and unemployment status) predicted higher adulthood SES later in their life (after a 10-year follow-up), but not vice versa. In conclusion, favorable socioeconomic environment in childhood appears to have a positive effect on offspring’s compassion in their middle adulthood. This effect may attenuate by middle age. High compassion for others seems to promote the achievement of higher SES in adulthood.

Family Socioeconomic Status, Educational Expectations, and Academic Achievement Among Chinese Rural-to-Urban Migrant Adolescents: The Protective Role of Subjective Socioeconomic Status

The adverse impact of a low family socioeconomic status (SES) on rural-to-urban migrant children’s academic achievement has been widely demonstrated. However, knowledge regarding the mechanisms underlying this relationship is limited. The current study aimed to examine the potential mediating effects of educational expectations and the moderating effects of subjective SES on the relationship between family SES and academic achievement among Chinese rural-to-urban migrant adolescents. A sample of 321 rural-to-urban migrant adolescents (48.2% girls; mean age = 11.73 years, SD = 1.16 years) was recruited in China. The results indicated that migrant adolescents’ educational expectations mediated the relationship between family SES and academic achievement. In addition, the link between family SES and educational expectations was weak among adolescents with higher levels of subjective SES. These findings suggest that subjective SES serves as a protective factor buffering the negative effects of a low family SES on migrant adolescents’ academic achievement through educational expectations.
