Diet structure and academic achievement of children from difficult families: a cross-sectional study of Chinese children

Abstract

ObjectivesWelfare policy focuses on vulnerable populations, such as children with difficult family backgrounds. Education is a crucial way to reduce poverty. This study explored the relationship between children’s diet structure and academic achievement and compared these across different family backgrounds.DesignA cross-sectional study was conducted to survey the health status of children from difficult families based on a random sampling method in 2018. Survey data were collected from children and their guardians with a questionnaire. A multi-sample latent class model and an ordinal logistic model were applied for data analysis.SettingThis study was conducted in 31 provinces nationwide. Two provinces in the Central (Shandong and Jiangxi), Eastern (Hebei and Henan) and Western (Chongqing and Shanxi) regions and one province in the Northeast (Liaoning) were selected considering different stratum of economic development.ParticipantsA total of 2099 children with difficult family backgrounds and 666 children from ordinary families were surveyed.ResultsThe dietary structure of children from ordinary families was significantly better than that of children with difficult or unstable family backgrounds (χ2 =9.178, p<0.01). Children from difficult families had an intake of dairy products and fruits below dietary standards. The difference in academic achievement between children in the balanced and deprived groups was statistically significant (OR=0.640, 95% CI 0.429 to 0.955). Other determinants of the academic achievement of children in difficult families were parents’ education level (OR=1.331, 95% CI 1.162 to 1.525), family economic status (OR=0.835, 95% CI 0.748 to 0.932) and parents’ academic concern (OR=0.373, 95% CI 0.252 to 0.553).ConclusionsTo address the differences between children from difficult families and ordinary families, policymakers should develop support policies for difficult children, guide the formation of a reasonable dietary structure. Besides, enhancing family closeness and fostering family nurturing behaviours are the keys to promote the good academic development of children from difficult families.

Peer factors and prosocial behavior among Chinese adolescents from difficult families

“…This study used data from a major 2018 Chinese Ministry of Education project, “Research on the Health Status of Children from Difficult Families.” We conducted a field survey in August 2018 that lasted one month. We recorded the preparatory work details in our previous work 21 . The inclusion criteria of ADF relied on the official definition from the Chinese Ministry of Civil Affairs.…”
