Associations between religious/spiritual beliefs and behaviours and dietary patterns: analysis of the parental generation in a prospective cohort study (ALSPAC) in Southwest England

Abstract

AbstractObjective:Religious/spiritual beliefs and behaviours (RSBB) have been associated with health outcomes, with diet a potential mediator of this relationship. We therefore explored whether RSBB were associated with differences in diet.Design:Dietary patterns and nutrient intakes were derived from food frequency questionnaire completed by pregnant women in 1991–1992 (mean age = 28·3 years, range = 15–46) and by the mothers and partners 4 years post-partum (mothers mean age = 32·3, range = 19–49; partners mean age = 34·5, range = 18–74). RSBB exposures measured in pregnancy included religious belief, affiliation and attendance. We first explored whether RSBBs were associated with dietary patterns in confounder-adjusted linear regression models. If associations were found, we examined whether RSBB were associated with nutrient intake (linear regression) and following nutrient intake guidelines (logistic regression).Setting:Prospective birth cohort study in Southwest England (Avon Longitudinal Study of Parents and Children; ALSPAC).Participants:13 689 enrolled mothers and their associated partners.Results:In pregnant women, RSBB were associated with higher ‘traditional’ (i.e. ‘meat and two veg’) and lower ‘vegetarian’ dietary pattern scores. Religious attendance and non-Christian religious affiliation were associated with higher ‘health-conscious’ dietary pattern scores. Religious attendance was associated with increased micronutrient intake and following recommended micronutrient intake guidelines, with weaker effects for religious belief and affiliation. Comparable patterns were observed for mothers and partners 4 years post-partum, although associations between RSBB and nutrient intakes were weaker for partners.Conclusions:RSBBs are associated with broad dietary patterns and nutrient intake in this cohort. If these reflect causal relationships, diet may potentially mediate the pathway between RSBB and health.
