Sex, disease count, years of full-time education, past occupation (NS-SEC), living alone, energy and alcohol intake, smoking, physical activity, self-rated health, diet change, Geriatric Depression Scale, standardized mini-mental state examination, disease count, number of medications, renal impairment, tooth count, swallowing problems, meal provision, luncheon club attendance, ability to go shopping and cook a hot meal were entered into the backward stepwise multivariate linear regression. Swallowing problems included dry mouth and difficulty swallowing for other reasons
