Socio-economic gradients in diet quality are well established. However, the influence of
material socio-economic conditions particularly in childhood, and the use of multiple
disaggregated socio-economic measures on diet quality have been little studied in the
elderly. In the present study, we examined childhood and adult socio-economic measures,
and social relationships, as determinants of diet quality cross-sectionally in 4252 older
British men (aged 60–79 years). A FFQ provided data on daily fruit and vegetable
consumption and the Elderly Dietary Index (EDI), with higher scores indicating better diet
quality. Adult and childhood socio-economic measures included occupation/father's
occupation, education and household amenities, which combined to create composite scores.
Social relationships included social contact, living arrangements and marital status. Both
childhood and adult socio-economic factors were independently associated with diet
quality. Compared with non-manual social class, men of childhood manual social class were
less likely to consume fruit and vegetables daily (OR 0·80, 95 % CI 0·66, 0·97), as were
men of adult manual social class (OR 0·65, 95 % CI 0·54, 0·79), and less likely to be in
the top EDI quartile (OR 0·73, 95 % CI 0·61, 0·88), similar to men of adult manual social
class (OR 0·66, 95 % CI 0·55, 0·79). Diet quality decreased with increasing adverse adult
socio-economic scores; however, the association with adverse childhood socio-economic
scores diminished with adult social class adjustment. A combined adverse childhood and
adulthood socio-economic score was associated with poor diet quality. Diet quality was
most favourable in married men and those not living alone, but was not associated with
social contact. Diet quality in older men is influenced by childhood and adulthood
socio-economic factors, marital status and living arrangements.
