Yes / This study aims to explore links between biraderi–a form of identity-based social grouping and stratification which cuts across religions among South Asians–and infant and child nutrition among British Pakistanis using data from the Born in Bradford cohort study. The study will entail a mixed-methods approach to (i) develop an operational framework of biraderi for epidemiologic analyses and apply it to longitudinal data from the Born in Bradford cohort study, (ii) quantify and describe child nutrition and dietary patterns for biraderi sub-groups, and (iii) investigate whether known mechanisms of identity-based segregation, graded inequality, and network effects operate through diet and nutrition in the UK. Using Krieger’s ecosocial theory as an integrative framework we will (iv) re-conceptualise and interpret the role of biraderi / caste in the social construction and embodied experience of how infants and children eat in the UK. Following a literature review on biraderi and health, we will convene and consult a lay consultation group in Bradford through focus groups and academic experts through a Delphi study to guide planning, implementation, interpretation and dissemination of our secondary data analysis. In addition to being the first study to look at biraderi-based nutritional inequalities in the UK, our study is innovative in that we will formally involve experts and users in the design and interpretation of our quantitative analyses. Findings will be applicable in any part of the world where children experience disadvantage linked to sociocultural hierarchy and identity. Our findings will be of particular use in (i) identifying women and children at particular risk of suboptimal breastfeeding practices, poor complementary feeding, and unhealthy diets in primary school in the UK, and (ii) elucidating the sociocultural pathways through which inequalities in population health nutrition outcomes are expressed. / This study is supported by an ESRC Secondary Data Analysis Initiative award to KB, HI and PA, jointly funded by the Economic and Social Research Council and Medical Research Council [Grant reference: ES/X012816/1].

Theory of mind (ToM) refers to a cognitive ability that enables one to attribute mental states (such as desires, emotions, beliefs) to self and others. In recent years researchers have identified cultural variations in the onset of ToM understanding in collectivist and individualist cultures. However, the findings of cross-cultural studies regarding these variations are inconsistent. The major aim of this innovative research was to investigate differences in the acquisition of ToM in children from a collectivist culture (Pakistan) and an individualist culture (UK). The second aim of the study was to assess the specific association between ToM and social competence in a culturally diverse sample. An additional aim of the study was to investigate the universality of various correlates of ToM such as executive functioning (EF), parenting styles, and maternal mental state talk. The findings of the studies demonstrated a significant delay in the acquisition of ToM in Pakistani children, when compared with Western children from individualist societies. These findings were corroborated by the results of novel cross-cultural study that compared the performance of White British, British Pakistani, and Pakistani children on a ToM scale. White British children outperformed both Pakistani and British Pakistani children on measures of ToM, EF, and social competence. The current findings also provide support for the association of mental state understanding with EF, social competence, parenting styles, and maternal mental state talk. These findings have important implications for the role of general (collectivist vs. individualist cultures) as well as specific cultural practices (such as parenting and education) in the acquisition of mental state understanding.
