During the last two decades there has been an alarming increase in the prevalence of overweight and obesity across Europe and North America. Debate continues about the apparent causes of this increase, with much of the blame being apportioned to excessive intakes of dietary fats and/or simple carbohydrates and reduced levels of physical activity. However, the rise in availability of snack foods has also been cited as a potential contributor to the prevalence of obesity (1) . Within the

In the present study a prospective investigation of the effects of eating pattern on body-weight change in the UK Women's Cohort Study (UKWCS) was undertaken. The UKWCS is a 10-year prospective investigation of the relationship between diet and cancer in middle-aged women across the UK. Full details of the cohort participants have been published elsewhere (2) . Using eating frequency and body-weight status as recorded in 1999-2000 and a 6-year follow-up 1929 women, initially aged 55 years on average (range 37-77 years), were included in a logistic regression analysis that assessed the association between change in body weight and eating pattern. The number of eating events per d was captured from 4 d semi-weighed food diaries, and body weights were obtained by self report. Each eating event was defined as any energetic solid, semi-solid or liquid food or drink that was separated from the next event by ‡ 15 min.
