Objective
To ascertain prospectively gender-specific associations between types and amounts of FH and weight gain, and investigate potential behavioural mechanisms.
Design and Methods
Prospective study of 3,701 adults British civil servants with repeated measures of difficulty paying bills or insufficient money to afford adequate for food/clothing (1985-88; 1989-90; 1991-93; 1997-99), and weight (1985-88; 1997-99).
Results
Persistent hardships were associated with adjusted mean weight change in women over 10.9 years, but no consistent pattern was seen in men. During follow-up, 46% of women gained ≥5 Kg. Women reporting persistent insufficient money for food/clothing had a significantly greater odds of gaining ≥5 Kg (1.42 [1.05, 1.92]) compared to no hardship history, which remained after SES adjustment (1.45 [1.05, 2.01]). The association between persistent difficulty paying bills and odds of excess weight gain was also significant (1.42 [1.03, 1.97]) but attenuated after considering SES (1.39 [0.98, 1.97]). Four health behaviours as single measures or change variables did not attenuate associations.
Conclusions
Results suggested strategies to tackle obesity must address employed women's everyday financial troubles which may influence weight through more biological pathways than classical correlates of economic disadvantage and weight.
