Difficult to have true cause and effect in humans. Measurement/observation of individuals: at given age, only once in a sample . Picture/snapshot: age group, gender group, specific population. Provides indo about g, m, performance and pa status. Have to be careful the sample size population is true to cross section of population. Repeated measurement/observation of the same group of individuals over a specific period of time. Provides info on status and change over time. Rate of change in g/m most useful: birth to age 3, take measurements more frequently, adolescence. Hard to keep participants in study over long period of time (morbidity and mortality) Need long term research team (often staff changes) Multiple cohorts: same start time/duration of study, different start and end ages, recruit subjects at different starting ages.
