Vulnerabilities in child well-being among primary school children: a cross-sectional study in Bradford, UK.

Although most primary school children aged 7-10 in our study had good levels of well-being on most indicators across multiple domains, fewer than 10% had no vulnerabilities at all, a worrying 10% had at least one vulnerability in all the four domains we studied and two-thirds had vulnerabilities of particular concern during the COVID-19 lockdowns.
