Smoking status and body mass index: A longitudinal study (2009)
Munafò, Marcus R., Tilling, Kate, Ben-Shlomo, Yoav
Introduction The general consensus is that smoking cessation leads to some degree of weight gain, although considerable disagreement remains regarding the magnitude and duration of this gain. ...

Advances in technology have improved our ability to measure physical activity in free-living humans. In the last few years, several large epidemiological studies in Europe and the United States have...

Aims To estimate the prevalence of alcohol and tobacco use among children at age 10 years and to investigate possible influences on this. Design Birth cohort study. Setting England. Participants A...
Objectively Measured Physical Activity and Fat Mass in a Large Cohort of Children (2007)
Andy R. Ness, Sam D. Leary, Calum Mattocks, Steven N. Blair, John J. Reilly, Jonathan Wells, ...
BackgroundPrevious studies have been unable to characterise the association between physical activity and obesity, possibly because most relied on inaccurate measures of physical activity and...
Tilling, Kate, Lawlor, Debbie A., Davey Smith, George, Chambless, Lloyd, Szklo, Moyses
The authors aimed to investigate the relation between components of adult height (leg and trunk length) and atherosclerosis in middle age, using data from 12,254 participants (aged 44–65 years) in...

Aims To investigate the association of breastfeeding with all-cause, cardiovascular, and ischaemic heart disease mortality. Methods and results A long-term follow-up of 4999 children originally...
Tilling, Kate, Sterne, Jonathan A. C., Szklo, Moyses
Standard methods for analysis of cohort studies may give biased estimates of exposure effects in the presence of time-varying confounding. Such effects may instead be estimated by using G-estimation....
Estimation of the incidence of stroke using a capture-recapture model including covariates (2001)
Tilling, Kate, Sterne, Jonathan AC, Wolfe, Charles DA
Background Capture-recapture is often used to assess completeness of a register. However, the usual two-source model relies on assumptions of independence of sources and equality of capture...
Capture-Recapture Models Including Covariate Effects (1999)
Tilling, Kate, Sterne, Jonathan A. C.
Capture-recapture methods are used to estimate the incidence of a disease, using a multiple-source registry. Usually, log-linear methods are used to estimate population size, assuming that not all...
Admissions for myocardial infarction and World Cup football: database survey
Carroll, Douglas, Ebrahim, Shah, Tilling, Kate, Macleod, John, Smith, George Davey
Wolfe, Charles D A, Smeeton, Nigel C, Coshall, Catherine, Tilling, Kate, Rudd, Anthony G
Objectives To identify ethnic differences in survival after stroke and examine the factors that influence survival.

Objectively Measured Physical Activity and Fat Mass in a Large Cohort of Children
Ness, Andy R, Leary, Sam D, Mattocks, Calum, Blair, Steven N, Reilly, John J, Wells, Jonathan, ...
A study with 5,500 12-year-olds shows an inverse association between physical activity and obesity, which is stronger in boys, and suggests that high-intensity activity is more important than total...
Early life determinants of physical activity in 11 to 12 year olds: cohort study
Mattocks, Calum, Ness, Andy, Deere, Kevin, Tilling, Kate, Leary, Sam, Blair, Steven N, ...
Objective To examine factors in early life (up to age 5 years) that are associated with objectively measured physical activity in 11-12 year olds.
G-estimation of the effect of exposures in longitudinal studies
Stata's st suite of commands for the analysis of survival time data allow flexible modeling of the effect of exposures which vary over time. A potential problem in such analyses is that other risk...
Controlling for time-dependent confounding using marginal structural models
Zoe Fewell, Frederick Wolfe, Hyon Choi, Miguel A. Hernán, Kate Tilling
Longitudinal studies in which exposures, confounders, and outcomes are measured repeatedly over time have the potential to allow causal inferences about the effects of exposure on outcome. There is...
G-estimation of causal effects, allowing for time-varying confounding
This article describes the stgest command, which implements G-estimation (as proposed by Robins) to estimate the effect of a time-varying exposure on survival time, allowing for time-varying...
