The effects of psychological factors on complementary feeding behavior have been widely described, yet the mechanisms underlying the complex relationships among personality traits, self-efficacy, and complementary feeding behavior remain unclear. This cross-sectional study was conducted using a multi-stage cluster sampling process to select caregiver-child dyads in Western rural China. Personality traits, self-efficacy, and complementary feeding behavior were evaluated respectively. Both multiple logistic regression and Bayesian network structure (BNs) were used to explore these associations. A total of 787 caregiver-child dyads were enrolled. Results from multiple logistic regression indicated that caregivers with medium (OR = 2.05, p < 0.001) or high (OR = 1.58, p = 0.04) levels of extraversion, as well as those with high self-efficacy recording complementary feeding (OR = 2.08, p < 0.001), significantly increased the likelihood of meeting the criteria for the Infant and Child Feeding Index (ICFI) qualification. Further, BNs were employed to elucidate the pathways of influence, revealing a direct association between the caregiver's level of extraversion, level of self-efficacy and the ICFI. Additionally, the analysis indicated that a caregiver's openness indirectly influenced the ICFI through its influence on self-efficacy regarding complementary feeding. This is one of few studies exploring associations between personality traits, self-efficacy, and complementary feeding behavior. The study highlights the importance of understanding individual differences in caregiving and suggests that interventions should focus on enhancing caregivers' self-efficacy, rather than solely targeting personality traits.
This paper examines whether education can play a role in mitigating gender inequality in the process of sectoral reallocation of labour. We exploit the exogenous variations in educational attainment induced by the implementation of the 1986 Compulsory Education Law (CEL) in China. Using data from the 2018 wave of the China Family Panel Studies (CFPS) and a cohort difference-in-differences (DID) approach, we find that the CEL narrowed the gender gap in education for rural residents, but it did not reduce gender inequality in labour market outcomes, such as wage labour participation and wage rate. Our analysis reveals that this persistent inequality in labour market outcomes can be attributed to gender differences in migration and occupational choices. Specifically, rural males exposed to the CEL were more likely to migrate outside local provinces and work in low-skilled manufacturing sectors, while rural females tended to stay within local counties and work in low-skilled service sectors. Furthermore, we provide evidence that their differential migration responses are driven by household labour divisions and social gender norms, rather than disparities in cognitive skills.
Background: Micronutrient powder (MNP or Yingyangbao, a dietary supplement that contains multiple vitamins and minerals) programs can reduce the risk of anemia among children. One such program in China distributed free MNP to children aged 6–24 months in poor rural areas. However, there are indications that the generation of primary caregiver (i.e., parent or grandparent) may influence MNP feeding behavior. The purpose of this study was to investigate the prevalence and influencing factors of effective MNP feeding behavior among parents and grandparents in a rural developing setting.
Methods: We conducted a cross-sectional study of 884 caregivers and children in formerly impoverished rural areas of Sichuan Province using multi-stage random sampling. Data were collected on caregivers’ MNP feeding behavior, their core perceptions and health beliefs about MNP, children’s responses to MNP, MNP delivery patterns, and demographic characteristics. Influencing factors of parents’ and grandparents’ MNP feeding behavior were analyzed using two-level logistic regression.
Results: Total effective MNP feeding behavior rate among caregivers was 40.95%. Grandparents demonstrated higher MNP adoption than parents (χ2 = 4.445, P = 0.035). After controlling for sociodemographic characteristics, grandparents were more likely than parents to achieve effective MNP adoption (OR = 1.360, P = 0.035); child’s preference for MNPs (ORparental subgroup = 1.736, ORgrandparental subgroup = 1.496; P < 0.050) and caregiver’s self-efficacy (ORparental subgroup = 1.157, ORgrandparental subgroup = 1.393; P < 0.050) were influencing factors of feeding behavior for caregivers of both generations. Parents were also influenced by perceived barriers to feeding MNPs (OR = 0.904, P = 0.040), while grandparents were more strongly influenced by child’s discomfort to MNPs (OR = 0.240, P = 0.023) and caregiver’s knowledge about MNPs (OR = 1.557, P = 0.014).
Conclusion: Future efforts to improve the feeding behavior of caregivers in MNP programs both in China and abroad should improve children’s preference for MNP by changing its composition and taste, and increase caregivers’ feeding self-efficacy through health education. Moreover, parents should be taught to cope with time and ability barriers that may limit MNP adoption, while grandparents should be emphasized the importance and potential side effects of MNP.
The diffusion of high-yielding crop varieties has been a key driver for agricultural productivity. This study examines the relationship between the adoption of high-yielding crop varieties of two staple crops—wheat and maize—and infant mortality in rural China. Using data from 1954 to 1987, we find a significant reduction in infant mortality linked to high-yielding crop varieties diffusion, an association that remains robust even after excluding the Great Famine years. We investigate potential mechanisms driving this relationship, including increased grain production, improved infant nutrition, and changes in maternal characteristics. Additionally, our analysis unveils a spectrum of heterogeneous relationships between high-yielding crop varieties adoption and infant mortality across factors such as infant gender, maternal characteristics, and policy regulation. These findings reaffirm the positive and lasting benefits of dissemination of high-yielding crop varieties for human welfare and provide valuable policy insights for developing nations grappling with food and nutritional insecurity.
Despite investments in teacher education programs, teacher shortages persist in rural areas of many low- and middle-income countries. Using data from 1860 tuition-free students, we examine factors influencing enrollment in China's Tuition-Free Normal Education (TNE) program and their implications for teacher recruitment and retention in rural schools. Descriptive analysis and OLS regression reveal that TNE students mostly come from larger, poorer families, and enroll for job security and financial benefits. Many aspire to teach but resist rural placements, risking non-compliance. These findings can guide the design and reform of programs to attract qualified teachers to rural areas in China and abroad.
