PARTICIPANTS: Participants were recruited from schools in the northern provinces of the Netherlands.

Assessing whether an association is causal requires an understanding of the strengths and weaknesses of the studys design as well as judgment about how the study findings fitThe most important advantage of cross sectional studies is that they are quick and relatively cheap to perform. Design, Application, Strengths Weaknesses of Cross-Sectional Studies. In a cross-sectional study, data are collected on the whole study population at a single point in time to examine the relationship between disease (or other health related state) and other variables of interest.

In medical research and social science, a cross-sectional study (also known as a cross-sectional analysis, transverse study, prevalence study) is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time—that is, cross-sectional data.

Strengths of cross-sectional study designs.disadvantages of cross-sectional studys. -Do not know temporal sequence -Selective survival -No risk calculation -Cannot determine etiology -Not good for studying rare diseases/exposures -Difficult to study diseases with short duration. Cross-sectional studies offer several advantages over other types of research design. Compared to longitudinal cohort studies, which are studiesAnother strength of cross-sectional studies is that when they are based on a representative sample of the population, their results can be generalized to Example of Cross Sectional Study Design.Therefore, cross sectional design consists of sampled groups which are selected and observed from a continuum to find out if there is any distinction between the various parts of the continuum. Design, Application, Strengths Weaknesses of Cross-Sectional Studies In a cross-sectional study, data are collected on the whole study population at a single point in time to examine the relationship between disease (or other health related state) and other variables of interest.

Someone may be able to sketch a vision perfectly but not be able to actually make it happen for example. Also, the strength of an animal study will be dependent on how closely the physiology of the test animal matches human physiology (e.g in most cases a trial with chimpanzees will be moreImportantly, like cross sectional studies, this design also struggles to disentangle cause and effect.

Strengths and Weaknesses of Cross-Sectional Studies.Occasionally, investigators perform a series of cross-sectional studies in the same population, say every 5 years. This design can be used to draw inferences about changing patterns over time. Strengths: Cross-sectional studies can be very useful. Since they can calculate the prevalence of disease, results can be compared to other studies and determine if there is aThis slides provides a quick review of the two descriptive study designs we discussed: cross-sectional and ecologic. 3 cross-sectional study. кросс-секционное, межгрупповое исследование тип исследования, предполагающий сравнение различных когорт в одно и то же время.

This mini-tutorial identifies the key features of a cross sectional study. It also identifies the type of data measure calculated and discusses the strengths and weaknesses of this study design. Cross-sectional studies make comparisons at a single point in time, whereas longitudinal studies make comparisons over time. The research question will determine which approach is best. Study design depends greatly on the nature of the research question. Conducting a Cross-Sectional Study Steps in building a cross-sectional study Practical Issues. Discussion of clinical example The data set The questions Confounding and interaction. Data analysis issues. Box 9.2 : Types of developmental research.
