DCross-sectional designs involve comparing different groups of people at one point in time, which can confound age with other variables of interest since differences observed may not solely be due to age. They are less likely than longitudinal designs to be influenced by cohort effects because they do not follow the same group of participants over time, thus avoiding changes that are specific to a particular generation.
