The influence of socio-economic status on child temperament and psychological symptom profiles.

The influence of socio-economic status (SES) on child temperament and psychological symptoms was examined using a nationally representative sample in Singapore. Data were available for 2169 children from 1987 families. Caregivers' reports were obtained on children aged 4-6. SES was operationalized as an aggregation of household income per capita, parental education level and housing type. Compared to their counterparts from higher SES families, children from low-SES families tended to exhibit (a) higher negative affectivity but lower effortful control, and (b) higher internalizing and externalizing symptoms. In addition, children with a 'resilient' temperamental profile (i.e. low negative affectivity and high effortful control) were more likely to come from families with much higher SES, relative to children with other profiles. Children with high internalizing symptoms tended to come from low-SES backgrounds, regardless of their externalizing symptoms. Among children with low internalizing symptoms, those with high externalizing symptoms came from lower SES backgrounds compared to those with low externalizing symptoms. Parental warmth and distress mediated the association between SES and child temperament and symptom profiles, with the exception of distress in the SES-temperament link. These findings supported the family stress model and highlighted the novel perspective of SES's influence on configurations of child temperament and symptom characteristics.

Pre-pandemic family resources and child self-regulation in children's internalizing problems during COVID-19: a multi-level social-ecological framework for emotional resilience.

Introduction: Children's psychological adjustment to adverse events can be determined by multiple risk and resilience factors. This study explored multi-level protective factors against children's internalizing problems and investigated the mechanism regarding how diverse environmental and child-level resources influence children's mental health in the context of COVID-19. Methods: Our participants included a nationally representative sample of 2,619 young children (48.3% girls) and their primary caregivers (95.1% mothers) in Singapore. They were a subset of the participants in the Singapore Longitudinal Early Development Study (SG LEADS). Data were collected over two waves-before the outbreak of the COVID-19 pandemic (Wave 1) when these children aged 3 to 6, and during the second year of the pandemic (Wave 2). Primary caregivers completed measures of verbal cognitive ability, self-control, economic stress, and positive and negative parental control in Wave 1. Children's self-regulation was assessed by the Delay of Gratification task in Wave 1, and their internalizing problems were rated by their primary caregivers in both waves. Other pre-pandemic family and community characteristics were collected as covariates. Structural equation modeling was performed. Results: Pre-pandemic parental resources (i.e., verbal cognitive ability, self-control, and low economic stress) predicted children's fewer internalizing problems during the pandemic and less aggravation of internalizing problems from before to during the pandemic, through more positive parental control (i.e., limit setting) and less negative parental control (i.e., harsh discipline). Moreover, children's self-regulation during early childhood was predicted by their primary caregivers' verbal cognitive ability and self-control, as well as positive parental control. Early childhood self-regulation further alleviated the aggravation of internalizing problems over time. Among the covariates, parental education, family income, parental psychological well-being, living with both parents, having a live-in domestic helper, and neighborhood quality also longitudinally predicted fewer child internalizing problems. Discussion: Our findings underscore the importance of nurturing children's emotional resilience under adverse and uncertain circumstances by boosting protective factors in their social-ecological system, including community-, family-, parent-, and child-level resources.

The influence of socioeconomic status and appearance-reality understanding on pre-schoolers' sharing and generosity.

Prosocial behaviour can be defined as any voluntary action that is performed to benefit another individual. Despite accumulating evidence of the importance of environmental variables (e.g., socioeconomic status; SES), and individual characteristics (e.g., theory of mind - ToM - skills), in influencing prosocial behaviours in young children, it is unknown how these factors relate to the underlying motivations for prosocial behaviours. Accordingly, both extrinsically (sharing) and intrinsically (generosity)-guided prosocial behaviours are measured in this study. We explore the influences of SES and ToM skills on young children's sharing behaviour and generosity, while controlling their age, working memory and language skills. Sixty-six 4- to 6 year olds (Mage = 5.24 years, SD = 0.73) from diverse SES (measured by parental education level) and ethnic backgrounds in Singapore completed tasks assessing the ToM measures of false belief and appearance-reality understanding, working memory, language skills, generosity, and sharing behaviour. The results of hierarchical regression analyses demonstrate that the father's education level and children's appearance-reality understanding were significant predictors of sharing, after controlling for age, working memory, language skills, and the mother's education level. Children's appearance-reality understanding was the sole predictor of children's generosity. Our findings highlight the impact of children's ability to hold different views of reality and their family's education levels on the development of sharing and generosity in early childhood.

Effects of socio-economic status on infant native and non-native phoneme discrimination.

Infants undergo fundamental shifts in perception that are reported to be critical for language acquisition. In particular, infants' perception of native and non-native sounds begins to align with the properties of their native sound system. Thus far, empirical evidence for this transition - perceptual narrowing - has drawn from socio-economically and linguistically narrow populations from limited world regions. In this study, infants were sampled across diverse socio-economic strata and linguistic development in Singapore. One hundred and 16 infants were tested on their ability to discriminate both a native phonetic contrast (/ba/ versus /da/) and a non-native Hindi contrast (/ta/ versus /ʈa). Infants ranged in age from 6 to 12 months. Associations between age and discrimination varied by contrast type. Results demonstrated that infants' native sensitivities were positively predicted by family SES, whereas non-native sensitivities were not. Maternal socio-economic factors uniquely predicted native language sensitivity. Findings suggest that infants' sensitivity to native sound contrasts is influenced by their family socio-economic status. RESEARCH HIGHLIGHTS: We investigated effects of socio-economic status on infant speech perception. Infants were tested on native and non-native speech discrimination. Socio-economic status predicted native speech discrimination. Maternal occupation was a key predictor of native speech discrimination.

Are centenarians successful agers? Evidence from China.

BACKGROUND: It is unclear to what degree centenarians are successful agers. We assess successful aging (SA) and its subtypes in a large Chinese sample. METHODS: Based on a large national sample of 18,311 Chinese centenarians, we first estimated the prevalence of SA among centenarians, and then used the Latent Class Analysis to classify centenarians into different types based on the five dimensions of SA. Multinomial regression analysis was used to examine how demographic, socioeconomic, and lifestyle covariates are associated with these identified types. RESULTS: 5.7% of centenarians fulfilled all five criteria of SA, and 1.3% failed all five criteria. The remainder could be classified into six types of SA. The regression analysis further revealed that these SA types were related to various social factors. For example, with timely access to medical care, centenarians were three times more likely to be successful agers. CONCLUSIONS: Centenarians demonstrate substantial heterogeneity in terms of achieving five SA criteria. Social factors are found to be significantly associated with centenarians' aging performances. Specific subtypes of SA among centenarians may be associated with and help explore different underlying biological-environmental mechanisms of exceptional longevity.

The home literacy environment mediates effects of socio-economic status on infant vocabulary development.

It is well attested that high socio-economic status (SES) is associated with larger vocabulary size estimates in young children. This has led to growing interest in identifying associations and mechanisms that may contribute to this relationship. In this study, parent-child reading behaviors were investigated in relation to vocabulary size in a large-scale study of linguistically and socio-economically diverse families. This study sampled 902 infants in Singapore, a multilingual society. Both single-language (dominant and non-dominant) and dual-language vocabulary size estimates were obtained and related to family SES, demographic details, and home literacy activities. Results demonstrated that both single-language (dominant and non-dominant) and dual-language infant vocabulary size estimates were predicted by parental education levels. Further analyses revealed that parent-child book reading activities mediated the relationship between parental education and infant vocabulary size. Findings suggest that shared book reading may narrow effects of socio-economic disparities on early language development. RESEARCH HIGHLIGHTS: Socio-economic status (SES) was examined in relation to infant vocabulary size in a linguistically and socio-economically diverse setting. Mediating effects of the home literacy environment on infant vocabulary size were measured. Socio-economic factors, notably parental education, had both direct and indirect effects on vocabulary size. The home literacy environment mediated effects of SES on infant vocabulary size.

The Country That Never Retires: The Gendered Pathways to Retirement in South Korea.

OBJECTIVES: Among all Organization for Economic Cooperation and Development countries, South Korean older adults work until the latest age. We investigate the extent to which work experiences over the life course and family circumstances can be associated with older workers' incentives to remain in the labor force beyond the statutory pension age. We explore gender-specific patterns of labor force exit and labor force re-entry in later life. METHODS: Using panel data of South Korean older workers and retirees from 2006 to 2016, we estimate multilevel discrete-time models with random effects to predict their labor force transition process that unfolds over time. RESULTS: Results show that skilled manual workers are less likely to exit employment and more likely to re-enter the labor force. A longer history of self-employment is related to later retirement. The relationship between career characteristics and the risk of retirement is only significant for men. Late-aged employment transition among women appears to be more related to family conditions. Women who receive financial support from adult offspring are more likely to remain out of the labor force but this relationship is not pronounced among men. DISCUSSION: Policies aimed at extending working lives need to provide various types of social support to older job seekers, especially those who had low-class jobs and those without family networks.

Childhood conditions and productive aging in China.

We investigate the impacts of childhood conditions on productive aging in China. Productive aging is defined as engagement in working, caring, and socially productive activities (volunteering, informal helping, etc.). Two theoretical frameworks are examined: (1) the pathway model that emphasizes later life health and socioeconomic conditions are related to dis(advantages) starting from childhood, and (2) the latency model that illustrates childhood experiences directly affect productive engagement due to biomedical influences or values and preferences formed during childhood. The 2011, 2013 and 2014 China Health and Retirement Longitudinal Studies (CHARLS) were used as these data sets provide both contemporaneous and retrospective information. The analytic sample consists of 5818 respondents aged 55 and above. We conduct multilevel analyses and path models to estimate the effects of childhood conditions, including family background (hukou - household registration - status and parents' education), neighborhood cohesion, subjective health and nutrition. Individual and family contemporaneous characteristics and clustered data structure were controlled for. The results largely support a pathway model in that childhood health and nutrition affect the likelihood of productive activities in later life through their influence on cognition and disabilities in old age. Moreover, family background and neighborhood cohesion are associated with productive activities via the effects through mid-life work, later life cognition, and disabilities. Results also provide some support for the latency model through the direct effect of neighborhood cohesion on socially productive activities, highlighting the importance of values formed in early life in shaping the motivations of productive engagement in later life. To conclude, we demonstrate that better childhood health, an advantaged family background, and values of helping others instilled in childhood affect older adults' productive engagement. Policies should be put in place to reduce socioeconomic disadvantages in childhood and also to cultivate cohesive community environments.

Long-Term Care for Older Adults in ASEAN Plus Three: The Roles of Family, Community, and the State in Addressing Unmet Eldercare Needs.

OBJECTIVE: To introduce this Special Issue that focuses on understanding the issues surrounding the long-term care (LTC) in selected societies in Southeast and East Asian countries. METHOD: We first provide demographic and socioeconomic context for these countries and then summarize the seven articles in this issue. RESULTS: The articles highlight the rapidly rising demand for LTC in this region in the next few decades given the declining fertility, lengthening life expectancy, and increasing migration. They also discuss challenges and strategies in meeting these demands. Most countries are ill prepared to cope with the demand for LTC with older adults heavily rely upon female family members for care. Elderly women in low-income households have the greatest unmet need. DISCUSSION: Home-based and community-based services are set to become an integral part of the LTC system. It is important to incorporate older adults' cultural norms and wishes in their care plan and provision.

An Ecological Framework for Active Aging in China.

OBJECTIVES: Against the background of emerging research interest in integrating Active Aging in long-term care policies, the study investigates the relationships between community environment and engagement in social activities (paid work, domestic care, participation in community and leisure activities) by older Chinese adults. Six indicators are derived from the economic, institutional, and sociodemographic environments of the communities under analysis. METHOD: The first wave of the China Health and Retirement Longitudinal Study (CHARLS) is used for empirical examinations. The sample includes respondents aged 50 years and above ( n = 6,290) from 307 communities. Random-intercept multilevel logistic models are employed. RESULTS: Economic environment is positively linked to engagement in paid work and grandparental childcare, community activities, and leisure activities. However, the effects decreased after including the indicators for the institutional and sociodemographic environments. We found that older adults are more likely to engage in community activities and leisure activities in communities and with a higher percentage of migrant population. DISCUSSION: To integrate Active Aging in the current long-term care policies in China, the study points out that residential community environment is crucial for older Chinese to enhance and sustain their involvement in family and communities before older adults rely on long-term care facilities. In particular, the relevance of institutional and sociodemographic environment provides policy makers to rethink about how to provide community-based long-term care.

Parental Spending on School-Age Children: Structural Stratification and Parental Expectation.

As consumption expenditures are increasingly recognized as direct measures of children's material well-being, they provide new insights into the process of intergenerational transfers from parents to children. Little is known, however, about how parents allocate financial resources to individual children. To fill this gap, we develop a conceptual framework based on stratification theory, human capital theory, and the child-development perspective; exploit unique child-level expenditure data from Child Supplements of the PSID; and employ quantile regression to model the distribution of parental spending on children. Overall, we find strong evidence supporting our hypotheses regarding the effects of socioeconomic status (SES), race, and parental expectation. Our nuanced estimates suggest that (1) parental education, occupation, and family income have differential effects on parental spending, with education being the most influential determinant; (2) net of SES, race continues to be a significant predictor of parental spending on children; and (3) parental expectation plays a crucial role in determining whether parents place a premium on child development in spending and how parents prioritize different categories of spending.

The black-white test score gap and early home environment.

Based on panel data for three age cohorts of children from the Panel Study of Income Dynamics, we examine how early home environment contributes to black-white achievement gaps at different developmental stages and the extent to which early gaps contribute to later racial achievement gaps. We find large black-white test score differences among children of all ages even before children start formal schooling. Except for the oldest cohort, the gaps for all tests widened when children's cognitive skills were assessed six years later. Racial achievement gaps in applied problem scores by grade three and letter-word scores by grade six, can be accounted for by child's characteristics, family socioeconomic background, and mother's cognitive skills. However, these covariates explain an increasingly smaller proportion of the black-white achievement gap as children advance to higher grades. Gaps in early cognitive skills are highly predictive of gaps at later ages, setting off a trajectory of cumulative disadvantage for black children over time. Our results underscore the key role of early home environment and the intergenerational roots of the persistent black-white achievement gap.

Measuring respiratory health in longitudinal social science surveys.

Objectively assessing respiratory health in longitudinal social science surveys would involve collecting pulmonary function measures on research participants, either in clinic settings or at home. These measures include indicators of volume (e.g., maximal amount of air blown in the first second of a forced exhalation) and airflow (maximal speed air is exhaled during a forced exhalation). Equipment options include office spirometry, portable spirometry, or home peak flow monitoring. Each option has different equipment and personnel costs. The types of research questions that could be answered using pulmonary function measures in longitudinal household surveys are quite broad, ranging from effects of socioeconomic status and race/ethnicity on respiratory health to social/environmental factors that contribute to respiratory health to the long-term social and economic consequences of respiratory health problems. Currently, such data are lacking. Given the potential payoffs in scientific knowledge, adding these measures to population-based surveys merits serious consideration.
