Bangladesh is one of the first signatory countries of the WHO Framework Convention on Tobacco Control (FCTC), which was ratified on 10 May 2004. The country passed the ‘Smoking and Tobacco Products Usage (Control) Act 2005’ on 15 March 2005 following the spirit of the WHO FCTC22 and amended it in 2013. Although the Act has imposed smoking restrictions in many public places and on public transportation, it has no provision to outlaw smoking in and around residential settings. The country also has the ‘National Housing Policy 2016’ to ensure accessible, sustainable, and quality housing for all of its citizens.23 Unfortunately, smoking in housing facilities has not been restricted by the policy as well. 1) The general characteristics of the participants, simulation design, flow, and simulation educational satisfaction were calculated as frequencies and percentages and means and standard deviations. A sample size of 136 was required after calculating the number of participants in the study using the G-power 3.1 program with an effect size of 0.15, a power of 0.90, and a significance level of 0.05 for regression analysis with eight expected independent variables.
Is Epidemiology a branch of public health?
Cross-sectional studies do not provide information from before or after the report was recorded and only offer a single snapshot of a point in time. Data on a number of aspects of the Australian population is gathered through completion of a survey within every Australian household on the same night. Cross-sectional studies equip scholars and policymakers with actionable data that can be acquired quickly, facilitating informed decision-making and the development of products or services. They are valuable for understanding the current status of a condition or behavior within a population, making them great for initial assessments. Whether you’re building a marketing strategy or performing a cutting-edge medical study, you can get started by creating an intuitive survey from QuestionPro.
What is a cross-sectional study?
The INACSL guidelines, revised in 2023, added professional development, suggesting that instructors should strive to provide high-quality simulation education that reflects the needs of learners with new knowledge related to simulation [4]. Therefore, in addition to theoretical preparation for professional development before starting simulation education, it seems necessary to participate in practical training to experience the role of learner and educator. In practice, cross-sectional studies will include an element of both types of design. Limitations of cross-sectional studies include the inability to make causal inferences, study rare illnesses, and access incidence. Are you considering whether a cross-sectional study is an ideal approach for your next research? Check out some of the key advantages and disadvantages of cross-sectional studies.
Prevalence Ratio/Risk Ratio and Excess Prevalence/Risk Difference
A reporting guideline’s primary goal is to ensure that published clinical research studies provide transparency in reporting a study’s conduct (what was done) and results. The guideline is a tool investigators can use to develop their manuscripts and offers a checklist of inclusion items for a published paper (Equator.network). The recommended items will help ensure that a reader can understand the manuscript, follow the study’s planning and how the research was conducted, the findings, and the conclusions (von Elm et al., 2014). Whereas epidemiology is the study of disease occurrence and transmission in a human population, epidemiological studies focus on the distribution and determinants of disease. Epidemiology may also be considered the method of public health—a scientific approach to studying disease and health problems.
In epidemiology and public health research, cross-sectional studies are used to assess exposure (cause) and disease (effect) and compare the rates of diseases and symptoms of an exposed group with an unexposed group. As demonstrated in table 2, 94.8% of the respondents (97.8% non-smokers vs 82.6% smokers) wanted smoke-free housing, whereas 5.2% (2.2% non-smokers vs 17.4% smokers) did not want smoke-free housing. Work-related variables including employment, field of expertise, weekly working hours, and night shifts. Exposure to the COVID-19 pandemic pertains to nurses who may come into touch with patients suspected or confirmed to have COVID-19, or find themselves in a situation that necessitates COVID-19 quarantine.

Data availability
Therefore, we allocated about one-third of the sample to Dhaka City and distributed the remaining two-thirds among the six cities equally. In the first stage, we randomly selected 10 municipality wards from each of the seven cities. Importantly, there are two city corporations under Dhaka City, and therefore we selected five municipality wards from each of the two city corporations. For each city, we prepared a separate list of only those MUH complexes that had a housing management committee.
What is epidemiology and its relationship to public health?
Both systems place randomized controlled trials (RCT) at the highest level and case series or expert opinions at the lowest level. RCTs are given the highest level because they are designed to be unbiased and have less risk of systematic errors. I. A well-designed randomized controlled trial, where feasible, is generally the strongest study design for evaluating an intervention’s effectiveness. A cross-sectional study is generally considered neither prospective nor retrospective because it provides a “snapshot” of a population at a single point in time. The information obtained from cross-sectional studies enables researchers to conduct further data analyses to explore any causal relationships in more depth.
What are some suitable cross-sectional study examples?
Key terms in this definition reflect some of the important principles of epidemiology. Cross-sectional studies can be either qualitative or quantitative, depending on the type of data they collect and how they analyze it. Often, the two approaches are combined in mixed-methods research to get a more comprehensive understanding of the research problem.

The authors presented a cross-sectional analysis to assess the prevalence of HIV and risk behaviors in male sex workers. The data were collected by interviewer-administered questionnaires (for sociodemographic and behavior data), clinical evaluation for sexually transmitted infections (STIs), and serological evaluation for STIs (including HIV). A cross-sectional study is a type of research design in which you collect data from many different individuals at a single point in time. In continuing with the obesity and sedentary activity level among HIV participants, the example below (see Table 1) describes the methods for calculating and discussing the results for an analytic cross-sectional study.
Depression and anxiety are the most common mental health illnesses worldwide [1]. Depression is a mood disorder that affects an individual’s thoughts and feelings and leads to persistent feelings of sadness and disinterest [2]. Anxiety is a group of mental disorders characterized by nervousness, apprehension, and fear [3]. Depression and anxiety disorders are major contributors to the mental health burden of adults [4].
They are useful for establishing preliminary evidence in planning a future advanced study. This article reviews the essential characteristics, describes strengths and weaknesses, discusses methodological issues, and gives our recommendations on design and statistical analysis for cross-sectional studies in pulmonary and critical care medicine. Analytic cross-sectional studies can provide the groundwork to infer preliminary evidence for a causal relationship (Mann, 2012). This design allows investigators to identify a population or sample and collect prevalence data to evaluate outcome differences between exposed and unexposed participants on a disease, phenomena, or opinion (Wang & Cheng, 2020). This design compares the proportion of participants exposed to the disease or phenomena of interest with the proportion of participants non-exposed with the disease or phenomena of interest (Alexander, 2015a).
In cross-sectional studies, researchers select a sample population and gather data to determine the prevalence of a problem. Cross-sectional studies can be done much quicker than longitudinal studies and are a good starting point to establish any associations between variables, while longitudinal studies are more timely but are necessary for studying cause and effect. However, cross-sectional studies differ from longitudinal studies in that cross-sectional studies look at a characteristic of a population at a specific point in time, while longitudinal studies involve studying a population over an extended period. Cross-sectional studies are designed to look at a variable at a particular moment, while longitudinal studies are more beneficial for analyzing relationships over extended periods.
On the other hand, the χ2 test or Fisher's exact test were utilized for categorical variables. The survey was conducted by contacting professors at one university in each of the Seoul, Daegu, and Jeonbuk regions by phone to ensure that the students had experience with simulation, explaining the purpose and methodology of the study, and asking for their cooperation. The recruitment document and study description were delivered through the fourth-year class representative.
A cross-sectional study (cross-sectional analysis or transverse study) offers an overview of a specific population in terms of an outcome at a given point in time. Cross-sectional studies are used in the fields of healthcare, social sciences, and economics. In this article, we cover cross-sectional study definition, its purpose, characteristics, and types of cross-sectional studies with examples.
They are also more likely to be influenced by what is known as selective attrition, which means that some individuals are more likely to drop out of a study than others. Because a longitudinal study occurs over a span of time, researchers can lose track of subjects. Individuals might lose interest, move to another city, change their minds about participating, etc.
Cross-sectional studies are usually cheaper to conduct than longitudinal studies, so they are ideal if you have a limited budget. An analytical cross-sectional study investigates the relationship between two related or unrelated parameters. Outside variables may affect the study while the investigation is ongoing, however. A descriptive cross-sectional survey or study assesses how commonly or frequently the primary variable occurs within a select demographic. Once the researcher has selected the ideal study period and participant group, the study usually takes place as a survey or physical experiment. We’ll explore examples, types, advantages, and limitations of cross-sectional studies, plus when you might use them.
