Marginal structure models (MSM) are causal models proposed to estimate the causal effect of time-vary treatments by controlling time-dependent confounders in observational studies. The objective of this thesis is to illustrate the fitting of an MSM for the causal effect of cognitive decline on BMI changes among old Mexican Americans participating in the Hispanic EPESE Cohort study. Based on MSM analysis, we reported that those suffered cognitive decline in later life will receive significant reduction in BMI by 0.1809 kg/m 2 on average (P-value=0.0305). We also conducted several sensitivity studies to explore different impacts on our MSM.
