Household income supplements in early childhood to reduce inequities in children's development

BACKGROUND

Early childhood interventions have the potential to reduce children's developmental inequities. We aimed to estimate the extent to which household income supplements for lower-income families in early childhood could close the gap in children's developmental outcomes and parental mental health.

METHODS

Data were drawn from a nationally representative birth cohort, the Longitudinal Study of Australian Children (N = 5107), which commenced in 2004 and conducted follow-ups every two years. Exposure was annual household income (0-1 year). Outcomes were children's developmental outcomes, specifically social-emotional, physical functioning, and learning (bottom 15% versus top 85%) at 4-5 years, and an intermediate outcome, parental mental health (poor versus good) at 2-3 years. We modelled hypothetical interventions that provided a fixed-income supplement to lower-income families with a child aged 0-1 year. Considering varying eligibility scenarios and amounts motivated by actual policies in the Australian context, we estimated the risk of poor outcomes for eligible families under no intervention and the hypothetical intervention using marginal structural models. The reduction in risk under intervention relative to no intervention was estimated.

RESULTS

A single hypothetical supplement of AU$26,000 (equivalent to ∼USD$17,350) provided to lower-income families (below AU$56,137 (∼USD$37,915) per annum) in a child's first year of life demonstrated an absolute reduction of 2.7%, 1.9% and 2.6% in the risk of poor social-emotional, physical functioning and learning outcomes in children, respectively (equivalent to relative reductions of 12%, 10% and 11%, respectively). The absolute reduction in risk of poor mental health in eligible parents was 1.0%, equivalent to a relative reduction of 7%. Benefits were similar across other income thresholds used to assess eligibility (range, AU$73,329-$99,864).

CONCLUSIONS

Household income supplements provided to lower-income families may benefit children's development and parental mental health. This intervention should be considered within a social-ecological approach by stacking complementary interventions to eliminate developmental inequities.

Economic instability and child maltreatment risk: Evidence from state administrative data

BACKGROUND

The effects of economic instability and the role of economic conditions preceding child protective services (CPS) involvement have not been fully considered in the child welfare literature.

OBJECTIVE

This paper investigates the link between earnings instability and CPS involvement. Specifically, it examines whether adequate access to safety net programs mitigates the likelihood of child welfare involvement when families encounter negative earnings shocks.

METHODOLOGY

The study used quarterly administrative data from a sample of at-risk families for CPS involvement in Wisconsin. Event history analysis was employed to estimate the relationship between earnings instability and subsequent child maltreatment investigations.

RESULT

Experiencing a negative earnings shock of 30% or more increases the likelihood of CPS involvement by approximately 18%. The effect diminishes and becomes nonsignificant when an earnings decline is compensated by benefit receipt. Each additional earnings drop is associated with a 15% greater likelihood of CPS involvement. Each consecutive quarter with stable income is associated with 5% lower probability of a CPS report. The results are more pronounced for abuse than neglect and are marginally significant for neglect reports.

CONCLUSION

Unfavorable economic instability is linked to greater CPS-involvement risk, particularly for child abuse. Moreover, accessing sufficient social benefits as supplemental income when negative earnings shocks occur serves to effectively buffer against the risk of child maltreatment, particularly among families with young children (ages 0-4).

An unconditional prenatal income supplement is associated with improved birth and early childhood outcomes among First Nations children in Manitoba, Canada: a population-based cohort study

BACKGROUND

In Manitoba, Canada, low-income pregnant women are eligible for the Healthy Baby Prenatal Benefit, an unconditional income supplement of up to CAD $81/month, during their latter two trimesters. Our objective was to determine the impact of the Healthy Baby Prenatal Benefit on birth and early childhood outcomes among Manitoba First Nations women and their children.

METHODS

We used administrative data to identify low-income First Nations women who gave birth 2003-2011 (n = 8209), adjusting for differences between women who received (n = 6103) and did not receive the Healthy Baby Prenatal Benefit (n = 2106) with using propensity score weighting. Using multi-variable regressions, we compared rates of low birth weight, preterm, and small- and large-for-gestational-age births, 5-min Apgar scores, breastfeeding initiation, birth hospitalization length of stay, hospital readmissions, complete vaccination at age one and two, and developmental vulnerability in Kindergarten.

RESULTS

Women who received the benefit had lower risk of low birth weight (adjusted relative risk [aRR] 0.74; 95% CI 0.62-0.88) and preterm (aRR 0.77; 0.68-0.88) births, and were more likely to initiate breastfeeding (aRR 1.05; 1.01-1.09). Receipt of the Healthy Baby Prenatal Benefit was also associated with higher rates of child vaccination at age one (aRR 1.10; 1.06-1.14) and two (aRR 1.19; 1.13-1.25), and a lower risk that children would be vulnerable in the developmental domains of language and cognitive development (aRR 0.88; 0.79-0.98) and general knowledge/communication skills (aRR 0.87; 0.77-0.98) in Kindergarten.

CONCLUSIONS

A modest unconditional income supplement of CAD $81/month during pregnancy was associated with improved birth outcomes, increased vaccination rates, and better developmental health outcomes for First Nations children from low-income families.
