Household transitions between ages 5 and 15 and educational outcomes: Fathers and grandparents in Peru.

BACKGROUND: Latin America has high rates of single motherhood and intergenerational coresidence, resulting in children experiencing changes in household composition - particularly with respect to fathers and grandparents. In other contexts, such changes have been shown to influence educational outcomes. OBJECTIVE: To test if the presence of grandparents and fathers in the household are differentially associated with educational outcomes during schooling years in Peru. METHODS: Young Lives longitudinal data consist of around 2,000 children who were followed from age 1 to age 15 between 2002 and 2017. Using value-added and child fixed effects models, I examine if the number of changes in household structure involving fathers and grandparents, the type of change (exit or entrance), and the identity of the household members are associated with cognitive outcomes. Persistence was tested as well as heterogeneous associations by child's age at transition and disadvantage. RESULTS: More than half the children experienced a change in household composition between ages 5 and 15. Father separation was associated with worse cognitive scores and lower likelihood of being on-grade. This was strongest if separation occurred when children were older. Grandparent presence in the household was not as strongly correlated with child outcomes, but results suggest that children have better cognitive performance after grandparent separation from the household. Associations between household composition and child outcomes were stronger if children were disadvantaged. CONTRIBUTION: This research provides evidence that fathers and grandparents are both important contributors to child educational outcomes in a context where three-generational households are common.

Family structure and child development in Chile: A longitudinal analysis of household transitions involving fathers and grandparents.

BACKGROUND: Adults support child development economically, socially, and emotionally. Household transitions may disrupt these support structures, impacting child development. OBJECTIVE: We document the large portion of children in Chile that experience biological-father and grandparent household transitions, and test if these transitions are associated with child vocabulary and behavior and if income could be a mechanism behind our findings. METHODS: We apply first-differences and lagged-dependent-variable analyses to a large, nationally representative, longitudinal survey of over 5,000 Chilean children. RESULTS: We find that children whose mothers separated from their parents' homes within the two years between two survey rounds have worse age-normalized Peabody Picture Vocabulary Test scores than children in households without such transitions. Changes in income per capita do not explain these associations. When fathers enter households between the two survey rounds there is a gain in income per capita but no association between father entrance and child's vocabulary score. Similarly, there is no significant association between fathers separating from the household and child vocabulary, though father departure is associated with lower income per capita. We find no association between household transitions and Child Behavioral Checklist (CBCL) scores. CONCLUSIONS: These findings provide evidence that Chilean grandparents promote language development when coresiding with their grandchildren and that Chilean fathers are an important source of household income. CONTRIBUTION: Our study examines fathers and grandparents simultaneously. We are able to take the directionality (i.e., movement in or out of the home) of biological father transitions into account.

Stunting in Infancy Is Associated with Decreased Risk of High Body Mass Index for Age at 8 and 12 Years of Age.

BACKGROUND: Effects of early-life stunting on adiposity development later in childhood are not well understood, specifically with respect to age in the onset of overweight and obesity. OBJECTIVES: We analyzed associations of infant stunting with prevalence of, incidence of, and reversion from high body mass index-for-age z score (BMIZ) later in life. We then estimated whether associations of infant stunting with BMIZ varied by sex, indigenous status, and rural or urban residence. METHODS: Data were collected from 1942 Peruvian children in the Young Lives cohort study at ages 1, 5, 8, and 12 y. Multivariable generalized linear models estimated associations of stunting (height-for-age z score <-2) at age 1 y with risk of BMIZ > 1 and BMIZ > 2 prevalence, incidence (moving above a BMIZ threshold between ages), and reversion (moving below a BMIZ threshold between ages) at later ages. RESULTS: After adjustment for covariates, stunting at age 1 y was associated with a lower prevalence of BMIZ > 1 at age 8 y (RR: 0.81; 95% CI: 0.66, 1.00; P = 0.049) and 12 y (RR: 0.75; 95% CI: 0.61, 0.91; P = 0.004), as well as a lower prevalence of BMIZ > 2 at age 8 y. Stunting was not associated with incident risk of BMIZ > 1 or BMIZ > 2. Stunting was positively associated at age 5 y with risk of reversion from BMIZ > 1 (RR: 1.22; 95% CI: 1.05, 1.42; P = 0.008) and BMIZ > 2. We found evidence that the association of stunting with prevalent and incident BMIZ > 1 was stronger for urban children at ages 5 and 8 y, and for nonindigenous children at age 8 y. CONCLUSIONS: Stunting predicted a lower risk of prevalent BMIZ > 1 and BMIZ > 2, even after controlling for potential confounders. This finding may be driven in part by a higher risk of reversion from BMIZ > 1 by age 5 y. Our results contribute to an understanding of how nutritional stunting in infancy is associated with BMIZ later in life.

Participation in the Juntos Conditional Cash Transfer Program in Peru Is Associated with Changes in Child Anthropometric Status but Not Language Development or School Achievement.

BACKGROUND: It is unclear what effects a conditional cash transfer (CCT) program would have on child anthropometry, language development, or school achievement in the context of the nutrition transition experienced by many low- and middle-income countries. OBJECTIVE: We estimated the association of participation in Peru's Juntos CCT with anthropometry, language development, and school achievement among children aged 7-8 y. METHODS: We used data from the Young Lives Study of a cohort born between 2001 and 2002. We estimated associations of the Juntos program with height-for-age z score (HAZ), body mass index-for-age z score (BAZ), stunting, and overweight at age 7-8 y separately for children participating in the program for ≥2 y (n = 169) and children participating for <2 y (n = 188). We then estimated associations with receptive vocabulary and grade achievement among children who had been assessed at age 4-6 y before enrollment in Juntos (n = 243). We identified control subjects using propensity score matching and conducted difference-in-differences comparisons. RESULTS: Juntos participation was associated with increases in HAZ among boys participating for ≥2 y [average effect of treatment among the treated (ATT): 0.43; 95% CI: 0.09, 0.77; P = 0.01] and for boys participating for <2 y (ATT: 0.52; 95% CI: 0.23, 0.80; P < 0.01). Among girls participating in the program for ≥2 y, BAZ declined (ATT: -0.60; 95% CI: -1.00, -0.21; P < 0.01) as did the prevalence of overweight (ATT: -22.0 percentage points; 95% CI: -42.5, -2.7 percentage points; P = 0.03). We observed no significant associations of Juntos participation with receptive vocabulary or grade attainment. CONCLUSIONS: CCT program participation in Peru was associated with better linear growth among boys and decreased BAZ among girls, highlighting that a large-scale poverty-alleviation intervention may influence anthropometric outcomes in the context of the nutrition transition.

The Cost of Insomnia and the Benefit of Increased Access to Evidence-Based Treatment: Cognitive Behavioral Therapy for Insomnia.

Insomnia is a highly prevalent, often chronic condition, which is left untreated or not treated according to recommended guidelines in most cases. This results in high health and financial burdens to society. The cost of untreated insomnia and the prevailing reliance on sedative-hypnotic use as a first-line treatment are evaluated in this article. The cost-benefit potential of cognitive behavioral therapy for insomnia is also assessed.

Mothers' labor market choices and child development outcomes in Chile.

This paper examines associations between labor market participation of Chilean mothers and the cognitive, language, and socio-economic development of their children. Using a nationally-representative sample of 3-year-old children, we test if mothers' work intensity in the two previous years is associated with child development outcomes; data were collected in 2010 when children were one year old, and again in 2012, when they were three years old. We find that children who were three years old with mothers who worked for higher fractions of their children's lives in the previous two years perform significantly better on all tests (cognitive, language, socio-emotional) than children whose mothers had worked less, while controlling for baseline test performance. These main effects did not remain significant with the inclusion of a wide range of socio-economic, demographic control variables, however. Our results were similarly null when using an IV analysis or a propensity score matching approach. We provide descriptive information on theoretical pathways by which maternal work may influence child development. Though several of these pathways (e.g. preschool, toys, maternal stress) seem to be associated with both maternal work and child development outcomes, the pathways are not sufficiently strong to generate an association between maternal work and child development. We conclude that Chilean mothers' employment in early childhood generally does not have an effect on child development.

Disparities in children's vocabulary and height in relation to household wealth and parental schooling: A longitudinal study in four low- and middle-income countries.

Children from low socio-economic status (SES) households often demonstrate worse growth and developmental outcomes than wealthier children, in part because poor children face a broader range of risk factors. It is difficult to characterize the trajectories of SES disparities in low- and middle-income countries because longitudinal data are infrequently available. We analyze measures of children's linear growth (height) at ages 1, 5, 8 and 12y and receptive language (Peabody Picture Vocabulary Test) at ages 5, 8 and 12y in Ethiopia, India, Peru and Vietnam in relation to household SES, measured by parental schooling or household assets. We calculate children's percentile ranks within the distributions of height-for-age z-scores and of age- and language-standardized receptive vocabulary scores. We find that children in the top quartile of household SES are taller and have better language performance than children in the bottom quartile; differences in vocabulary scores between children with high and low SES are larger than differences in the height measure. For height, disparities in SES are present by age 1y and persist as children age. For vocabulary, SES disparities also emerge early in life, but patterns are not consistent across age; for example, SES disparities are constant over time in India, widen between 5 and 12y in Ethiopia, and narrow in this age range in Vietnam and Peru. Household characteristics (such as mother's height, age, and ethnicity), and community fixed effects explain most of the disparities in height and around half of the disparities in vocabulary. We also find evidence that SES disparities in height and language development may not be fixed over time, suggesting opportunities for policy and programs to address these gaps early in life.
