Longitudinal associations between perceived father and grandparent support of mothers in early childhood, and maternal mental health
This study shows a link between infant care assistance patterns and maternal mental health. Mothers transitioning from assisted to sole care in the first postpartum year may face declining or stagnant psychological health, suggesting that family members offer support in infant care to share the caregiving responsibilities
Maternal empowerment, feeding knowledge, and infant nutrition
Background: Maternal empowerment - the capacity to make decisions within households - is linked to better child feeding and nutritional outcomes, but few studies have considered the mediating role of caregiver knowledge. Further, existing literature centres primarily on the husband-wife dyad while overlooking grandmothers as important childcare decision-makers. Methods: We collected primary data through household surveys in 2019 and 2021 from 119…
Rural China and the gender gap in early social-emotional development
"Las lanzas se convertirán irrevocablemente en arados"
El artículo se propone analizar la fundación del primer Instituto agrario del Ecuador mediante una reconstitución del itinerario de su director, el médico siciliano José Indelicato, que permitirá esclarecer el doble contexto en que se creó el establecimiento: la difusión del socialismo utópico, que marcó el recorrido de Indelicato, y el auge de la agronomía como ciencia específica, que llevó a la creación de las primeras escuelas de agricultura e…
The home language environment in rural China
In this paper, we present the first ever findings using the LENA system to measure the home language environment of young children from poor rural communities in China. We found that the home language environment of lower-SES household was significantly worse than high-SES households, and demonstrated the importance of the home language environment to language skills, pointing to a need for more high-quality studies of the home language environme…
Prevalence of anaemia and associated factors among infants under 6 months in rural China
Objective: To examine Hb level and anaemia status among infants under 6 months of age in rural China. Design: A cross-sectional survey collected data among infants under 6 months and their primary caregivers in Sichuan, China. Anaemia was defined using both the WHO and China Pediatrics Association thresholds. Multivariable linear regression was used to identify relevant factors among two age groups ( Setting: Eighty townships were selected in Sic…
The Salience of Information
Besides increasing knowledge, there is another potential mechanism at work when information is delivered to a treatment group: increasing the salience of existing knowledge. We use data from a randomized controlled trial of a health information campaign to explore the relative importance of this additional mechanism in a real-world environment. The health information campaign addressed the benefits of wearing eyeglasses and provided information m…

La contrarrevolución en el exilio
El artículo busca analizar las prácticas políticas de los conservadores y clérigos ecuatorianos exiliados en Pasto en los primeros años de la Revolución liberal, las cuales iban desde las expediciones armadas hasta una intensa actividad editorial. La experiencia del exilio contribuyó a redefinir el conservadurismo ecuatoriano, pero también reveló la porosidad de la frontera entre Ecuador y Colombia y el carácter transnacional del enfrentamiento e…
Perinatal Mental Health Problems in Rural China
Background: Perinatal mental health is important for the well-being of the mother and child, so the relatively high prevalence of perinatal mental health problems in developing settings poses a pressing concern. However, most studies in these settings focus on the demographic factors associated with mental health problems, with very few examing social factors. Hence, this study examines the prevalence of the depressive, anxiety and stress symptom…
Early Childhood Reading in Rural China and Obstacles to Caregiver Investment in Young Children
Studies have shown that nearly half of rural toddlers in China have cognitive delays due to an absence of stimulating parenting practices, such as early childhood reading, during the critical first three years of life. However, few studies have examined the reasons behind these low levels of stimulating parenting, and no studies have sought to identify the factors that limit caregivers from providing effective early childhood reading practices (E…
Passive versus active service delivery
We present the results of a cluster-randomized controlled trial that evaluates the effects of a free, center-based parenting intervention on early cognitive development and parenting practices in 100 rural villages in China. We then compare these effects to a previous trial of a home-based intervention conducted in the same region, using the same parenting curriculum and public service system, accounting for potential differences between the stud…
La rivalité entre Guayaquil et Quito à l'aube de la Révolution libérale, 1894-1895
La rivalité entre Quito et Guayaquil s’inscrit sur le temps long et a souvent été analysée par l’historiographie équatorienne. Cet article cherche à aborder la question d’un point de vue conjoncturel, en se focalisant sur deux évènements survenus à l’aube de la Révolution libérale, l’expulsion du sénateur libéral Felicísimo López du Sénat en 1894 et la proclamation du chef libéral Eloy Alfaro comme Chef Suprême de la République à Guayaquil en 189…
Conditional cash transfers, uptake of maternal and child health services, and health outcomes in western rural China
The CCT program generated modest improvements in the uptake of MCH services and mothers' knowledge of MCH services in poor rural areas of Western China. These improvements, however, did not translate into substantial improvements in child health outcomes for two potential reasons: poor CCT implementation and the low quality of rural health facilities
Parental Migration and Early Childhood Development in Rural China
Nearly one-quarter of all children under age 2 in China are left behind in the countryside as parents migrate to urban areas for work. We use a four-wave longitudinal survey following young children from 6 to 30 months of age to provide first evidence on the effects of parental migration on development, health, and nutritional outcomes in the critical first stages of life. We find that maternal migration has a negative effect on cognitive develop…
From Quantity to Quality
A key challenge in developing countries interested in providing early childhood development (ECD) programmes at scale is whether these programmes can be effectively delivered through existing public service infrastructures. We present the results of a randomised experiment evaluating the effects of a home-based parenting programme delivered by cadres in China’s Family Planning Commission (FPC)—the former enforcers of the one-child policy. We find…
Breastfeeding and the Risk of Illness among Young Children in Rural China
Poor rural areas in China exhibit the country's highest rates of child mortality, often stemming from preventable health conditions such as diarrhea and respiratory infection. In this study, we investigate the association between breastfeeding and disease among children aged 6−24 months in poor rural counties in China. To do this, we conducted a longitudinal, quantitative analysis of socioeconomic demographics, health outcomes, and breastfeeding …
Structural Equation Modeling (SEM) of Cysticercosis in School-Aged Children in Tibetan Rural Farming Areas of Western China
Neurocysticercosis (NCC) significantly contributes to morbidity in developing countries. We recently published a study of prevalence and risk factors in school-aged children in three mountainous areas in Sichuan province of western China. Using structural equation modeling (SEM) on data from that study to guide intervention planning, here we examine risk factors grouped into three broad interventional categories: sociodemographics, human behavior…
Do Infant Feeding Practices Differ Between Grandmothers and Mothers in Rural China? Evidence From Rural Shaanxi Province
The overall goal of this study is to examine whether infant feeding practices differ between mothers and grandmothers in rural China. We randomly sampled 1383 caregivers of infants aged 18 to 30 months living in 351 villages across 174 townships in nationally designated poverty counties in rural areas. Results show that a high fraction of caregivers of 18- to 30-month-old children living in low-income areas of rural China do not regularly engage …
Quién es y dónde está la Argolla? La familia Caamaño-Flores-Stagg durante el período progresista en Ecuador, 1883-1895
The article aims to elucidate the meaning of the word “Argolla”, used by conservative as well as liberal opponents to criticize the nepotism of the progressive governments directed by the Caamaño-Flores-Stagg clan between 1883 and 1895. First of all, the term “Argolla” is exactly defined, before establishing its genealogy and spreading history through the analysis of the enlightened satirical press of that period. The detailed study of the “Argol…

China’s Invisible Crisis
This article explores the problem of cognitive delays among toddlers in rural China and the role of their caregivers in producing low levels of cognition (i.e., low IQ). According to the results of a well-tested international scale of child development, the Bayley Scales of Infant Development (BSID), cognitive delays are alarmingly common, and nearly half the toddlers in our sample score an IQ of less than 84 on the BSID test (more than one stand…
Survey using incognito standardized patients shows poor quality care in China’s rural clinics
Over the past decade, China has implemented reforms designed to expand access to health care in rural areas. Little objective evidence exists, however, on the quality of that care. This study reports results from a standardized patient study designed to assess the quality of care delivered by village clinicians in rural China. To measure quality, we recruited individuals from the local community to serve as undercover patients and trained them to…

Text Messaging and its Impacts on the Health and Education of the Poor
China’s Left-Behind Children
China's rapid development and urbanization have induced large numbers of rural residents to migrate from their homes to urban areas in search of better job opportunities. Parents typically leave their children behind with a caregiver, creating a new, potentially vulnerable subpopulation of left-behind children in rural areas. A growing number of policies and nongovernmental organization efforts target these children. The primary objective of this…

Parental migration and smoking behavior of left-behind children
Parental migration is associated with a significant increase in smoking behavior among children. Intervention studies that target LBC would help to develop strategies to reduce smoking among rural children. Gender-specific strategies and anti-smoking education also appears to be needed to reduce tobacco use among rural LBC
The gender gap among school children in poor rural areas of western China
Our findings suggest that with the exception of non-cognitive outcomes, anemia and standardized math test scores, the gender gap in our study areas in China appears to be diminishing
Impact of Text Message Reminders on Caregivers’ Adherence to a Home Fortification Program Against Child Anemia in Rural Western China
Objectives. To test whether text message reminders sent to caregivers improve the effectiveness of a home micronutrient fortification program in western China. Methods. We carried out a cluster-randomized controlled trial in 351 villages (clusters) in Shaanxi Province in 2013 and 2014, enrolling children aged 6 to 12 months. We randomly assigned each village to 1 of 3 groups: free delivery group, text messaging group, or control group. We collect…
