A complex interplay of life-course risk factors makes it challenging to disentangle the effect of loneliness from other factors and to assess underlying mechanisms when using traditional approaches.</p><p><strong>Methods: </strong>We applied the parametric g-formula with the Health and Retirement Study (1996-2018; n = 34 774; aged 50-80 years) to simulate an intervention estimating the effect of preventing loneliness on cognitive function.
