1. Cross-sectional studies measure the exposure and the outcome at the same time. 2. Cross-sectional studies estimate the prevalence of a disease or condition. 3. Cross-sectional studies cannot establish a temporal relationship between the exposure and the outcome.

Across-sectional study is an observational study in which the exposure and the outcome are determined at the same time point for each study participant. Cross-sectional studies comprise the simplest individual-level observational study design and are usually relatively inexpensive and easy to conduct compared with case-control or cohort studies.

Cross-sectional studies and methodology
Osteoporosis International, 2012Dear Sir, As I read the study by Patil et al. [1], I noticed that they have not stated several important points; in the methods section, the authors did not state the number of participants they contacted or the method used (telephone or direct interview?). Did they contact all of the study universe?

Cross-sectional studies are related to sample surveys. In both types of studies a sample S is taken from the target population U, for example by one of the sampling plans presented in Sect. 12.2. The basic difference between the two studies resides in their purpose and, consequently, in the way they are being evaluated. As remarked in Sect.

Abstract In a cross-sectional study the occurrence (prevalence) of the disease under study for the ‘exposed’ is compared with the same occurrence in the non-exposed. The exposure and disease status is examined for the same time period. We do not have data to establish exposure status before the onset of the disease.

Researchers investigated public perception, anxiety, and behaviour with regard to the outbreak of swine flu.1 A cross sectional survey was used, with random dialling of telephone numbers in England, Scotland, and Wales. In total, 997 adults aged over 18 years—who had heard of swine flu and spoke English—were interviewed between 8 May and 12 May 2009 ...

In cohort studies, subjects are followed in a forward direction from exposure to outcome, and inferential reasoning is from cause to effect. In case-control studies, subjects are investigated in a backward direction from outcome to exposure; inference is from effect to cause.

In a cross-sectional study, all in a given population or a random sample from this population define the source population. The disease and its possible determinants are all recorded at a given point in time. This introduces a temporal ambiguity in the possible cause–effect association and for this reason most cross-sectional studies have survey ...
