A research study done at one time, not over the course of time. A cross-sectional study might be a study of a disease such as AIDS at one point in time, to learn its prevalence and distribution within the population. Also known as a synchronic study.

An investigation involving a sample of elements selected from the population of interest that are measured at a single point in time.

A 'snapshot' observation of a set of people at 1 time. This type of study (sometimes called a cross-sectional survey) contrasts with a longitudinal study, which follows a set of people over [..]

A cross-sectional study compares different individuals to each other at the same time—it looks at a cross-section of a population. The differences between those individuals can confound with the effec [..]

A type of epidemiological study that aims to describe the relationship between a disease or outcome and other factors of interest as they exist in a subset of a population at a particular point in time. Since both the outcome and the factors are measured at the same point in time these studies are not strong at showing causal relationships. (See al [..]

A study of a single sample at one point in time in an effort to understand the relationships among variables in the sample

A cross-sectional study is one type of study in which people of different ages are examined at the same time(s). This is usually done with cohorts, so that researchers can examine how people of differ [..]

A descriptive, observational study in which one or more subject groups are evaluated at one point in time to describe the population(s) of interest, assess the prevalence of a condition of interest, or evaluate the correlations between possible risk factors and a condition of interest.

In survey research, a study in which data from particular subjects are obtained only once. Contrast with longitudinal studies, in which a panel of individuals is interviewed repeatedly over a period o [..]

A study that measures the prevalence of health outcomes and/or determinants of health in a population at a point in time or over a short period of time.

A cross-sectional study is one type of observational study, in which the researcher does not perform any intervention (such as administering a medicine).Cross-sectional studies are primarily used to f [..]

The observation of a defined population at a single point in time or time interval. Exposure and outcome are determined simultaneously.

a study of a group of people at one point in time to determine whether an exposure is associated with the occurrence of a disease. Because the disease outcome and the exposure (e.g., nutrient intake) [..]

The observation of a defined population at a single point in time or time interval. Exposure and outcome are determined simultaneously.

A study of a population at a single point in time.

A cross-section is a random sample of a population, and a cross-sectional study examines this sample at one point in time. Successive cross-sectional studies can be used as a substitute for a longitud [..]
