Head start participation and school readiness: evidence from the Early Childhood Longitudinal Study-Birth Cohort.

Using data from the Early Childhood Longitudinal Study-Birth Cohort (n ≈ 6,950), a nationally representative sample of children born in 2001, we examined school readiness (academic skills and socioemotional well-being) at kindergarten entry for children who attended Head Start compared with those who experienced other types of child care (prekindergarten, other center-based care, other nonparental care, or parental care). Using propensity score matching methods and ordinary least squares regressions with rich controls, we found that Head Start participants had higher early reading and math scores than children in other nonparental care or parental care but also higher levels of conduct problems than those in parental care. Head Start participants had lower early reading scores compared with children in prekindergarten and had no differences in any outcomes compared with children in other center-based care. Head Start benefits were more pronounced for children who had low initial cognitive ability or parents with low levels of education or who attended Head Start for more than 20 hr per week.

Socioeconomic Gaps in Early Childhood Experiences

This study compares the early life experiences of kindergarteners in 1998 and 2010 using two nationally representative data sets. We find that (a) young children in the later period are exposed to more books and reading in the home, (b) they have more access to educational games on computers, and (c) they engage with their parents more, inside and outside the home. Although these increases occurred among low- and high-income children, in many cases the biggest changes were seen among the lowest-income children. Our results indicate narrowing but still large early childhood parental investment gaps. In addition, socioeconomic gaps in preschool participation grew over this period, despite substantial investments in public preschool. Implications for early socioeconomic achievement gaps are discussed.

Head Start and children's nutrition, weight, and health care receipt

Using a sample of low-income children from the Early Childhood Longitudinal Study-Birth Cohort (N ≈ 4,350) and propensity-score weighted regressions, we analyzed childrens nutrition, weight, and health care receipt at kindergarten entry, comparing 1) Head Start participants and all non-participants, and 2) Head Start participants and children in prekindergarten, other center-based care, other non-parental care, or only parental care. Overall, we found that compared to all non-participants, Head Start participants were more likely to receive dental checkups but showed no differences in getting medical checkups; they were also more likely to have healthy eating patterns but showed no differences in Body Mass Index (BMI), overweight, or obesity. However, these results varied depending on the comparison group-Head Start participants showed lower BMI scores and lower probability of overweight compared to those in other non-parental care, and the effects on healthy eating and dental checkups differed by comparison group.

Material Hardship and Alcohol Use among Low-income Households in South Korea

This study aimed to examine the association between material hardship and alcohol use among low-income households in Korea, with particular attention to whether the association was mediated by family conflict and self-esteem. Using a nationally representative sample of 960 low-income households, this study conducted a path analysis to test a structural model liking material hardship to alcohol use through family conflict and self-esteem. The significance of indirect paths was tested by a Sobel test. This study found that experiencing material hardship was directly associated with low levels of coping skills for family conflict and low levels of self-esteem, but not with alcohol use. However, material hardship was indirectly associated with alcohol use through low levels of coping skills for family conflict as well as low levels of self-esteem. The findings of this study suggest that experiencing material hardship among low-income households would be a socio-structural stressor for alcohol use, particularly in that it increases secondary role and intra-psychic strains. Implications to address material hardship and alcohol use among low-income households were discussed.

Hard Times and Harder Minds: Material Hardship and Marital Well-Being Among Low-Income Families in South Korea:

Experiencing material hardship may bring various negative consequences for married couples and family members. However, little is known about this topic in Korea. Using a nationally representative sample from the Korean Welfare Panel Study, we examined how material hardship was associated with marital well-being among low-income families in Korea, separately for husbands (i.e., male household heads) and wives. Overall, we found experiencing any material hardship was associated with lower levels of satisfaction of both family life and spousal relationship, consistently for husbands and wives. We also found depression and self-esteem partially mediated the associations in both groups. Furthermore, among individual items of material hardship, experiencing food hardship was associated with lower levels of satisfaction of family life for both husbands and wives, whereas experiencing problems with credit was associated with lower levels of satisfaction of both family life and spousal relationship for wives but not for husbands.

Preschool attendance and school readiness for children of immigrant mothers in the United States

We examined the associations between preschool attendance and academic school readiness at kindergarten entry among 5-year-old children of immigrant mothers in the United States using data from a US nationally representative sample (Early Childhood Longitudinal Study—Birth Cohort, N = 1650). Comparing children who were in preschool (Head Start, prekindergarten, or other center-based preschool) to children being cared for exclusively at home, analyses using both ordinary least squares regressions with rich controls and with propensity score weighting consistently showed that attending preschool was associated with higher reading and math skills. Analyses focused on specific type of preschool revealed that children attending prekindergarten (but not Head Start and other center-based preschool) had higher reading and math skills than those in parental care. Analyses focused on hours of preschool attendance indicated that children’s reading skills benefited from attending more than 20 hours per week of Head Start or prekindergarten. Attending preschool, especially for full days, increases the school readiness of children of immigrants.

Material hardship and self-rated health among low-income households in South Korea

ABSTRACT Concerns over poverty and health inequality are growing in South Korea. Using advanced statistical methods including lagged-dependent variable and fixed-effects approaches, we investigated whether experiencing material hardship (MH) was associated with self-rated health (SRH) among low-income households in South Korea. This study found that the experience of MH was positively associated with higher likelihood of reporting poor SRH (OR = 1.42, p < .05) and that experiencing two or more items of MH presented more harmful influence on SRH (OR = 2.02, p < .001). This study also found that the negative association between MH and SRH was stronger among the unemployed households.

Preschool and Academic School Readiness Among Young Children of Asian and Hispanic Immigrant Mothers

ABSTRACT Preschool is an important developmental context for children of immigrants that can help them succeed in later life. In this study, we examine the association between preschool and academic school readiness among young children of Asian or Hispanic immigrant mothers. A secondary data analysis was conducted using data (n ≈ 1,550) collected in the Early Childhood Longitudinal Study-Birth Cohort. Results show that attending preschool (mostly prekindergarten or other center-based care) was associated with better academic school readiness at the year of participation among children of both Asian and Hispanic immigrant mothers; such beneficial associations were found at kindergarten entry among Asian children, but not Hispanic children. Furthermore, more-pronounced beneficial influences of preschool on academic school readiness were found at the year of participation among children of home language mothers in both groups, but such more-pronounced benefits were gone at kindergarten entry in both groups. These findings suggest that the differences between the two groups in maintaining the benefits from preschool may be associated with different home environments. Future research is needed to look specifically at the mechanisms of how attending preschool is related to academic school readiness among children of immigrants.
