“…Overall, our findings support the hypothesis that psychosocial adversity negatively impacts this basic form of social cognition. Consistent with previous studies on the same cohorts, we did not find associations with measures of adversity at 6 months, lending further support to the idea that effects of adversity emerge with age, ( Xie et al, 2019a , Xie et al, 2019b , Jensen et al, 2021 ). At 24 and 36 months higher levels of verbal abuse and family conflict predict poorer social auditory discrimination.…”

“…Exposure to biological and psychosocial adversity has been reliably linked to consequences on overall brain and cognitive development in LMICs ( Jensen et al, 2019 ; Jensen et al, 2021 ; Tarullo et al, 2017 ; Wijeakumar et al, 2019 ). To develop concrete strategies of prevention and intervention, the mechanisms underlying associations between adversity and development must be understood.…”

There is strong support for the view that children growing up in low‐income homes typically evince poorer performance on tests of inhibitory control compared to those growing up in higher income homes. Unfortunately, the vast majority of the work documenting this association has been conducted in high‐income countries. It is not yet known whether the mechanisms found to mediate this association would generalize to children in low‐ and middle‐income countries, where the risks of exposure to extreme poverty and a wide range of both biological and psychosocial hazards may be greater. We examined relations among early adversity, neural correlates of inhibitory control, and cognitive outcomes in 154 5‐year‐old children living in Dhaka, Bangladesh, an area with a high prevalence of poverty. Participants completed a go/no‐go task assessing inhibitory control and their behavioral and event‐related potential responses were assessed. Cortical source analysis was performed. We collected measures of poverty, malnutrition, maternal mental health, psychosocial adversity, and cognitive skills. Supporting studies in high‐income countries, children in this sample exhibited a longer N2 latency and higher P3 amplitude to the no‐go versus go condition. Unexpectedly, children had a more pronounced N2 amplitude during go trials than no‐go trials. The N2 latency was related to their behavioral accuracy on the go/no‐go task. The P3 mean amplitude, behavioral accuracy, and reaction time during the task were all associated with intelligence‐quotient (IQ) scores. Children who experienced higher levels of psychosocial adversity had lower accuracy on the task and lower IQ scores.

“…Among adults, Zhang and colleagues reported that healthy lifestyle only mediated a small proportion (3.0% to 12.3%) of the association between low SES and higher risk of mortality and cardiovascular diseases ( 27 ). These results suggest that poor household wealth at early life may have a direct or causal link to suboptimal life-course health outcomes, which may result from persistent structural changes due to deprivations during pregnancy ( 28 ). Our results that household wealth at pregnancy was associated with adolescent HAZ, cognitive development and emotional and behavioral health agree well with this hypothesis.…”

BackgroundParental household wealth has been shown to be associated with offspring health conditions, while inconsistent associations were reported among generally healthy population especially in low- and middle- income countries (LMICs). Whether the household wealth upward mobility in LMICs would confer benefits to child health remains unknown.MethodsWe conducted a prospective birth cohort of children born to mothers who participated in a randomized trial of antenatal micronutrient supplementation in rural western China. Household wealth were repeatedly assessed at pregnancy, mid-childhood and early adolescence using principal component analysis for household assets and dwelling characteristics. We used conditional gains and group-based trajectory modeling to assess the quantitative changes between two single-time points and relative mobility of household wealth over life-course, respectively. We performed generalized linear regressions to examine the associations of household wealth mobility indicators with adolescent height- (HAZ) and body mass index-for-age and sex z score (BAZ), scores of full-scale intelligent quotient (FSIQ) and emotional and behavioral problems.ResultsA total of 1,188 adolescents were followed, among them 59.9% were male with a mean (SD) age of 11.7 (0.9) years old. Per SD conditional increase of household wealth z score from pregnancy to mid-childhood was associated with 0.11 (95% CI 0.04, 0.17) SD higher HAZ and 1.41 (95% CI 0.68, 2.13) points higher FSIQ at early adolescence. Adolescents from the household wealth Upward trajectory had a 0.25 (95% CI 0.03, 0.47) SD higher HAZ and 4.98 (95% CI 2.59, 7.38) points higher FSIQ than those in the Consistently low subgroup.ConclusionHousehold wealth upward mobility particularly during early life has benefits on adolescent HAZ and cognitive development, which argues for government policies to implement social welfare programs to mitigate or reduce the consequences of early-life deprivations. Given the importance of household wealth in child health, it is recommended that socioeconomic circumstances should be routinely documented in the healthcare record in LMICs.
