The association between snacking frequency (per unit increase) and measures of adiposity by sex and BMI status: The Fenland Study, UK (n 10 092). Data are β-coefficients and 95 % confidence intervals from multiple linear regression analysis. Comparison uses model 2, which is adjusted for age (years), alcohol (units/d), smoking status (current smoker/non-smoker), age at completing full-time education (years), test site (Cambridge, Ely, Wisbech), main meal (frequency/d), light meal (frequency/d), drink-only snack (frequency/d), plasma vitamin C (µmol/l), energy intake (MJ/d), physical activity energy expenditure (kJ/kg per d) and screen time (h). No interaction with BMI was noted between snacking and visceral fat thickness in men. Snacking frequency was estimated using an eating pattern questionnaire reflecting usual eating habit over a 24-h period. Energy intake was estimated using a FFQ (see the ‘Methods’ section).
