This study has some limitations. Parenting or other aspects of the family environment may be unmeasured confounders. Although the analysis did not account for these factors due to data availability, parent-reported child eating behaviors were included as a covariate along with other drivers of family climate (e.g., socioeconomic factors, parent marital status), which may account for some residual confounding. Another limitation relates to measurement. Single-item questions assessing diet are subject to measurement error. Relatedly, parents’ reports of child prosociality may be incomplete because they may not be privy to children’s behaviors when outside of their care. The prosociality measure used in these analyses may also be limited conceptually. Multidimensional indices would facilitate more nuanced investigations across different behavior types than the unidimensional scale administered in the MCS. Finally, findings were from United Kingdom children born in 2000 and may not be generalizable to other geographies or cohorts. Nevertheless, this study also has numerous strengths, including a large sample size, longitudinal design, and extensive covariate adjustment.
