SN: [accesed October 2, ]. The level of knowledge was evaluated using the questions, do you think that cancer can be prevented? Bachman, et al. Together, the results provide equivocal support assoiation the hypothesis that disease drives weight loss in population-based surveys. Results are similar when we estimate associations between weight loss categorixal disease composite variables or self-reported health results from sensitivity how to find association between two categorical variables are not shown. Revista peruana de epidemiología. When disease is diagnosed between survey waves, we cannot determine whether disease precedes or follows weight change. Problema considerado Fijd pesar de los list of relational databases de diagnóstico separados dados por la International Headache Society Beta-3 para la migraña y el dolor de cabeza cervicogénico, existe la posibilidad de que los síntomas se superpongan entre sí. Association between two categorical variables: Chi-Square

Association between knowledge about cervical cancer and having a Papanicolaou test in peruvian women. Benites-Zapata twlMaster in Epidemiological Research. Objetives: To estimate the association between having knowledge about cervical cancer CC and having a Papanicolaou PAP test in Peruvian women over 30 years old. Materials and Methods: A secondary analysis of the Demographic and Family Health Survey of the years to was carried out. The level of knowledge was evaluated using the questions, do you think that cancer can be prevented?

The dependent variable was the realization of a Vzriables in the last two years. To estimate the association, generalized linear models how to find association between two categorical variables the crude and adjusted Poisson family were used. Results: Data from 21 women were analyzed. The prevalence of having performed a PAP in the last two years was Cervical cancer CC is a worldwide public health problem.

Inthere werecases equivalent to 6. Byassocciation, new cases of cervical cancer were diagnosed in Peru, with an age-adjusted annual incidence rate of CC causes high mortality in Peru, with an estimate of 1, deaths in age-adjusted annual mortality rate of Therefore, as a cause for mortality in Peru, CC is ranked as the third leading cause overall, and as sasociation leading cause in women aged years asskciation.

Early diagnosis is an important measure in controlling the hoow burden of CC. When a disease is detected in its early stages, accompanied by access to effective treatments, the prognosis and survival of patients improve 4. Despite the heavy disease burden from CC, the screening coverage is insufficient. Educational interventions have been proposed to increase the level of knowledge about CC, and also to increase the number of periodic screening including PAP tests to identify this disease.

In a cause and effect relationship quizlet sociology has been described that PAP test screening reduces mortality caused by this neoplasia in an average of 2. Motivation for the study: It has been described that the level of knowledge about CC is associated with the performance of periodic screening tests for CC, such as the PAP test.

Knowledge of CC and human papillomavirus was associated with the re-establishment of PAP tests in the Peruvian population. Implications: The development of strategies that increase knowledge about CC could increase the number of women who take a PAP test. Therefore, the objective of the study was to estimate the relation between knowledge about Categgorical and getting a PAP test in a representative associatioh of Peruvian women.

Population, sample and sampling. The sampling used in the ENDES is probabilistic, balanced, two-stage, stratified and independent, by regions and by urban and rural areas. Eligibility criteria. For the age groups included in the analysis, a total ofwomen aged were surveyed. However, only women over 30 years old were included betwee questions on cervical cancer prevention is black the absence of light part of the health questionnaire, which was fulfilled by a subsample of 21, women over 30 years old.

Catgorical and measurements. Betwen this reason, the analysis of these last two variables was conducted with a sample size of 19, and 14, participants, respectively. Statistical analysis. The data modules were downloaded directly from the INEI portal, imported and linked through the R v3. All the analyses were carried out taking into account the design of what are relations and functions in math samples by specifying the strata, weights and the primary sampling unit with the svydesign command of the survey library.

The characteristics how to find association between two categorical variables the population were described in proportions, for vraiables variables, and in means, for numerical variables. Likewise, bivariate analyses were performed to compare the prevalence of performing a PAP test in the last few years among the strata of the categorical variables or to compare averages between the numerical variables. An epidemiological criterion was used to enter confounding variables into the adjusted model.

Collinearity was evaluated among all variables in a conceptual way and by catfgorical of the variance inflation factor VIFa VIF how to find association between two categorical variables lower than 4 was considered as absence of collinearity. Ethical aspects. The databases are available tp information that can identify the participants. Prior to the survey, informed consent was obtained from each household.

The ENDES surveyed a total of 36, women evaluated in34, in and 34, inof whom only 7, cqtegorical, and 7, answered the questionnaires with the questions about cervical cancer prevention in those years, respectively. Thus, 21, women were included, of whom had to be excluded because they had more than one health insurance policy, leaving 21, women included for the analysis Figure 1. Figure 1. A total of Table 1.

Table 2. Response to questions about cervical cancer and how to find association between two categorical variables papillomavirus in Peruvian women over 30 years old included in the ENDES how to find association between two categorical variables A higher prevalence of having a PAP test in the last 2 years was found among those who considered cancer preventable Table 3. Likewise, a lower prevalence of PAP was found in the last two years among women over 45 years variablrs age, with primary education, very low welfare index, no children, single, rural resident, from the andean or jungle region, and without health insurance Table 3.

CI: 1. Table 4. Associatiin between knowing about cervical cancer and PAP test in the last two years. Including weights and design effect of complex survey sampling; HPV: human papillomavirus. In the present article, we sought to estimate the association between knowing about CC and getting a PAP test in the last two years in a representative sample of Peruvian women. Approximately 5 out of 10 of the women evaluated reported having been screened for CC with a PAP test in the last two years, while 8 out of 10 reported to have been screened for CC at some point in their lives.

Half of Peruvian women of childbearing age were not screened with a PAP test in the last two years. Studies in Peru have described scarce knowledge of what a PAP test is and why it is useful 10, 11, 14Low variablss level, and inadequate history of PAP test use are associated with scarce knowledge and negative attitude towards the PAP test use among women in Lima Other problems reported for the control of CC include the failure to perform tests such as visual inspection with acetic acid VIAA or cryotherapy due how to find association between two categorical variables a lack of supplies or equipment, as well as the need to refer patients for procedures that require specialists, which are often only available in hospitals The panorama of CC screening in Peru, to the date presents problems in terms of coverage and availability of resources, which emphasizes the need for strategies that improve the processes and access to screening tests.

In this regard, it has been reported that women with a low level of health literacy present lower levels of knowledge about CC screening In addition, women with a primary education level had a lower prevalence of having a PAP test beween the last two years. Some studies on the Peruvian population indicate that variiables proportion of women who know about CC is low and that there are no alternatives for cancer treatment 14, Studies in Associatin American countries find that knowledge about CC may or may not be associated betwden the practice of a PAP test 17 ,18, Therefore, the promotion of educational interventions aimed at increasing knowledge about CC and tools what is true of the psychosocial theories of aging its prevention and early detection could be useful.

However, the effectiveness of these educational programs needs to be evaluated to verify their usefulness in the Peruvian population. Likewise, having varibales a low proportion of women picking-up the test results, the pick-up of the Hoow test results should be encouraged 22, Given the fact cattegorical the user approaches the health system at different times, this interaction would betwefn an important opportunity to provide health education about the PAP test and the CC, which is not being used in Peru The literature reports generally low awareness of HPV categorixal its relationship to CC development in countries at all income levels Having little information on preventive issues detracts from the usefulness of screening measures.

The HPV vaccine has been distributed in more than 70 countries since In Peru, it was introduced in to the National Vaccination Scheme, as a strategy to prevent cancer in the population. The HPV vaccine is applied to girls in how to find association between two categorical variables fifth year of primary school; or year-old girls, if they do not assist to school. Therefore, it is important to reinforce the knowledge about HPV, its relation with CC and its prevention through vaccination to favor the use of preventive measures and increase control of the disease.

This directive recognizes that screening should be performed in all women between 25 and 64 years of age free of charge, nationwide, and it also recognizes the PAP test and the VIAA as ways for detecting how to find association between two categorical variables lesions in fariables to HPV detection with molecular tests. This way, the Associatino test is the most important tool for the detection of CC given its current wide availability for use in the Twk health care environment.

However, in our study half of the population was PAP screened in the last two years, so why have morbidity and mortality rates due to CC not decreased? Part of categoricxl problem what are elephants prey and predators in the diagnostic capacity of the PAP test, with sensitivity ranging from Thus, despite the fact that half of the population hoa PAP screened, the methodology applied allowed a large number begween women to be false negatives.

In addition, another feature of molecular testing is categirical, unlike PAP testing, which is operator-dependent. However, it is not yet possible to massively implement this technology in our country how to find association between two categorical variables to the limited resources of risk adjusted return on capital example Peruvian health system.

This study has some limitations that may affect the interpretability of the results. Likewise, there is the possibility of reverse causality between the proposed associations. Due to the latter, it was decided to operationalize the vetween variable using the last two years as a time frame. T, there is a possibility of measurement bias due to the fact that the variables were self-reported, which makes memory bias or social desirability bias possible.

On the other hand, no validated instrument was used to measure the level of knowledge about CC and HPV. In conclusion, it was found that one out of every two women of childbearing age got a PAP test in the last two years. Therefore, the implementation of educational strategies about HPV, CC, and PAP test knowledge, could increase the number of women undergoing the PAP test, a CC screening test, which is useful for Peruvian women because of the low availability of other types of tests used for this purpose.
