Results of an Intervention Model in Intestinal Parasitosis in Parents Havana 2019-2020

An educational intervention study on intestinal parasitism was carried out in parents of parasitized children of Capitan San Luis de Marianao Elementary School, Havana in the period May 2018-2019, with the purpose of modifying the knowledge in these parents against some hygienic-sanitary aspects in order to reduce the incidence of disease through the application of a program of educational activities. Knowledge was determined through the use of a structured questionnaire. And social activities From a total of 125 parents, a random sample was selected and the questionnaire was administered to 40 parents at the beginning of the study and 6 months after the intervention. Variables such as age, level of education, level of knowledge about the concept, risk factors, routes of transmission, hygienic-sanitary measures and complications of this disease were analyzed. The intervention was effective, allowing satisfactory changes in the level of knowledge of the group studied, with group work constituting an element that allowed enriching and strengthening new methods in order to reduce the incidence of this disease.

immune system becomes more susceptible to the presence of this infection and therefore tends to control or modulate the infection. This is why the infection may trigger more obvious and serious symptoms in the course of the first years of life. Also, in younger patients, the infection may be more severe due to the immaturity of the system in this pediatric stage. Epidemiological and etiological studies have detected different environmental and individual factors that can influence favoring or hindering of parasitic infection through actions on the parasite or on the host [2][3][4][5].
Motivated by the incidence of intestinal parasitic disease associated with unfavorable environmental conditions and the ignorance present in the population and also influenced by not having similar studies carried out in this area beforehand, we determined that this research was vital, with the purpose of modifying the knowledge in these parents in order to reduce the incidence of the disease.

Introduction
Children are likely to acquire parasitic diseases, mainly caused by those parasites whose infectious form penetrates orally. In the transition from breast feeding to preschool age, when they begin their locomotion, their range of action, contact with the environment increases; this increases the risk of contracting parasitic diseases [1].
The patient's age over time has been an important factor when presenting a parasitic infection since the

Method
For the realization of the Educational Intervention, 3 stages were designed: 1. Diagnostic Stage 2. Intervention stage itself

Diagnostic stage
The parents of children who make up the universe were cited and their consent was requested to participate in the intervention, selecting those that were the object of study, who were filled out with the informed consent form (Annex I), and subsequently they were conducted a survey individually (Annex II), qualifying the knowledge before the intervention where the variables of interest for the investigation were taken.

Operationalization of variables:
Age: Quantitative discretized variable. It was taken in completed years and grouped in a five-year manner. This allowed, together with the classification of the level of schooling, to have an adequate vision of the cognitive sphere of the population under study.
Schooling: Ordinal discrete quantitative variable. Distributed as established by the Ministry of Education.

Level of Knowledge:
Qualitative dichotomous variable. Characterized by the items evaluated.
According to evaluation criteria that will be described below: Information on the knowledge about intestinal parasites was obtained through 8 questions, which had the following evaluation criteria: • Knowledge about Intestinal Parasites.
• Knowledge about the main risk factors that can influence acquisition of the infection.
• Knowledge of the transmission pathways of Intestinal Parasites. 8 items • Knowledge on treatment of drinking water.
• Knowledge on the frequency of treating drinking water.
• Knowledge about the correct disposal of solid and liquid residuals.
• Knowledge of sanitary hygienic measures to prevent Intestinal Parasite infection.
• Knowledge about the main complications that a child with this infection could have.
After assessing the knowledge by questions, a general evaluation was carried out, where the total sum of

Material and Methods
General aspects of the study An educational intervention study was conducted with the parents of parasitized children belonging to the Capitan San Luis Elementary School of the Marianao Municipality, Havana in the period from May 2018-2019, with the purpose of modifying knowledge about some hygienic-epidemiological aspects referring to this disease through the application of a program of educational activities.

Study universe
The universe consisted of 195 parents of children and those who gave their consent to participate in the research were included.
The following criteria were taken into account:

Inclusion criteria
1. Willingness to participate in the intervention.
2. Reside in the health area.
3. Be fit physically and mentally. 4. Be dispensed in the study area.

Exclusion criteria
1. Not completing the inclusion criteria mentioned above.

Exit Criteria
1. Leave the investigation.
2. Death or disabling illness during the intervention.

Sample
A random sample was taken, by simple random method, this being constituted by 40 parents of the group of dispensed children, which represents 56.4% selected by statistical probability formula.
The following equation was applied to calculate the sample size and its selection so that it is representative: whom a survey (Annex II) was applied before and after the educational intervention.

Information processing techniques:
The information obtained before and after the educational intervention was analyzed using the statistical package SPSS, version 11.5.
The information was summarized in double entry tables, using the number and percentage as a summary measure.
The results obtained were presented in containment tables and where there are conditions for their application, the McNemar test was used for a significance of 0.05 and with 95% reliability (p less than 0.05). From the afore mentioned it follows that the boxes a and d are the ones that really measure the effectiveness or not of the intervention.

Analysis technique:
We proceeded to analyze all the information obtained through the description and all the questions was considered up to a value of 100 points, being evaluated with knowledge of:

•
Adequate: If they scored 70 or more points.
• Inadequate: If they scored less than 70 points.

Intervention stage
The community educational intervention consisted of a program of activities in the form of a 3 month workshop, consisting of 24 hours. This was divide in 8 hours per month, 2 hours per week.
Classes were taught by the author, in a classroom of the same Primary School, Monday and Wednesday from 3 to 5 pm.
Participants were divided into two groups methodologically (A and B) for the development of the training. The topics were previously updated and reviewed by the author and the tutor. Participatory techniques and educational games were applied.

Evaluation stage
Information gathering technique: An extensive and thorough literature review of the subject was carried out in the various national and foreign publications available at the National Medical Library of Havana, in addition to the author's experience in other works on the same subject, as well as computerized systems installed, using the information received by Informed and the Internet. The libraries of the Finlay-Albarran Faculty of Medicine were also visited by the Vice Department of Communicable Diseases of the Provincial Center of Hygiene and Epidemiology.
The primary data was collected by the author himself through a face-to-face interview with the parents of the primary school children immersed in the study, to Source: Sociodemographic survey In Table 1, knowledge on the definition of intestinal parasitism is observed, most parents were predominately did not know the definition (n = 37; 92.5%). Although after the intervention, there was a 97.5% modification, that is, only one of the parents still ignored the definition after the intervention.
In Table 2, the risk factors that may influence the onset of the disease were specified, where ignorance prevailed in the parents before the educational intervention, such that 87.5% considered not treating drinking water, with hand and vegetable washing identified as the most important risk factors.
Through implementation of the program of activities, 95% of parents were able to acquire better knowledge, allowing the disease to be seen in pediatric ages.
In Table 3, the main routes of transmission were taken into account in order to assess the knowledge that parents had before the intervention, concluding that 34 participants represented by 85% had a high degree of discussion of each statistical table and the use of information provided by national and international studies, which allowed us to comply with the proposed objective and reach conclusions. The information was summarized in double entry tables, using the number and percentage as a summary measure.

Ethical aspects
This study was approved by the Finlay Albarran Medical Sciences Ethical Board.

Results
In Figure 1, the age distribution of the participating parents is observed, with 32.5% of the parents belonging to the age group of 20-24 years (n = 13). Figure 2 shows the distribution of parents by education level, the 70% of participants had basic secondary level (n = 28), followed by 16.6% with a bachelors (n = 6).
Source: Sociodemographic survey   quency of treating drinking water increased to Always in 92.5% of the participants.
In Table 6, the improper collection of liquid and solid waste by parents is observed, with 85% of them not disposing them properly, 62% of parents mainly use street garbage disposal, 70% performed their physiological needs in latrines, which do not meet sanitary hygienic requirements. This favors the appearance of vectors, negative factors for the child population which suffers more strongly from intestinal parasitism. After the intervention it was achieved that 100% of the participants knew the correct form of waste collection and its disposal.
In Table 7, the sanitary hygienic conditions related to intestinal parasite infection as observed; unfavorable ignorance in the ways in which that intestinal parasites are transmitted. Achieving a satisfactory result after the intervention reaching 100% knowledge, In Table 4, the level of knowledge shown of measures to treat drinking water, noting that before the educational intervention 70% of parents under study were unaware of their importance. This situation was reversed as 100% of the participants knew what the measures were to treat the water and its purpose from several points of view six months after the intervention, with the aim of improving its quality.
In Table 5, we observe the frequency of drinking water treatment, in which 77.5% of parents never tried, reversible situation immediately after the educational intervention, which we see in the result that the fre-

Conclusions
The intervention carried out through the application of a program of educational and participatory activities was effective, allowing satisfactory changes in the level of knowledge of the group studied, constituting group work an element that allowed enriching and strengthening new methods in order to reduce the incidence of this disease.

Discussion
At present, the modality of educational intervention has gained great importance, since positive results have been obtained in vulnerable groups in the community [6].
The Educational Intervention has been effective in different health matters in which it has been used, such is the example of the School for hypertensive, diabetic, asthmatic, among others, obtaining satisfactory results, since morbidity and mortality due to other causes have decreased, ensuring that trained patients are able to know their disease better and develop rules of their own behaviors for each of them and that they become facilitators and disseminators of the knowledge acquired, encouraging the masses to incorporate [6][7][8].
In order to carry out community intervention stud-sanitary hygienic conditions was performed by a total of 33 participants (82.5%), values present before applied the educational intervention, being able to assess after using it the level of knowledge achieved by parents rose to 100%.
In Table 8, the ignorance of the complications of parasitic infection present in the parents is observed, which represents 92.5%, some erroneous aspects were identified as abdominal pain with 60%, after the educational intervention we managed to raise the knowledge of parents to 100% explaining also that there are symptoms that are aggravated and at the same time constitute complications. Table 9, the evaluation of the knowledge of parents before and after the educational intervention, the aspects evaluated, which were predominantly represented by 32 participants inadequate for 80%.
However, after carrying out the program of activities, it was possible to modify favorably the knowledge of the participants, as can be seen in Figure 1, and raise them to 95%.
The results obtained guarantee the applied intervention as satisfactory, being able to modify the knowledge with statistically significant results for p < 0.05.   any disease is the elimination of all risk factors and predisposing factors to it. Control over all environmental factors must be maintained. All possible disinfection techniques should be used, especially food, objects or animals with which we interact [23].
Water is an important transmission pathway for intestinal parasites and therefore it is important for the population to be aware of treatment options for water that will be used for human consumption, which will constitute a risk factor for the disease as well as a hygienic measure to prevent infection by intestinal parasites.
From the sanitary hygienic point of view, bacteria, excessive mineralization, high levels of protozoan compounds and other organisms are eliminated. From the aesthetic point of view, the correction of smell, taste and turbidity is pursued. From an economic point of view, we are interested in eliminating corrosives [24].
Water is the natural habitat of many pathogenic species, whose abundance and diversity is determined by the availability of dissolved nutrients, water and food such as vegetables that are related here has great epidemiological importance as a vehicle for biological transmission of some parasitic agents, a high incidence of intestinal parasitism was reported in a study carried out last year in patients where the administration of unwashed food and improperly treated or improperly purified water is appreciated [24].
This study coinciding with others that showed that houses with little or no drinking water service and that are not treated, the inhabitants have greater infection by parasites, together with the lack of health education, total ignorance shown by the representatives of children from the most elementary hygienic measures that must be taken into account [25].
As much as the hygiene of food as boiling water for daily consumption is very important and that every person must know and be aware that with these measures a large part of the battle in the eradication of diseases such as parasitism is won intestinal. ies it is very important to determine the variables: Age and Level of education.
The age for the contribution of the experiences offered to the group and the school level greatly influences the state of health of the population, because in one way or another the cultural hygienic level of each community decreases or increases, the degree of awareness, reaching or not to know the main problems and factors that affect health and actively participate with health workers in activities with a view to modifying or eliminating these factors [9][10][11].
Low levels of schooling negatively influence the individual and collective health of the population since health actions are not fully assumed by the low health culture [12].
The evidence of a high intellectual level leads to a low incidence of diseases, this means that as the intellectual level improves, there is a lower risk of suffering from intestinal parasites, given the total sanitary hygienic measures necessary to avoid it, so it is proposed a low incidence in developed countries and its high in underdeveloped countries [13][14][15].
The results obtained by the author do not coincide with the research published in Mexico in 2007 where the authors conducted a study on 429 children between 6 and 36 months of age and obtained information about the family and their family environment, to relate it to the incidence of intestinal parasitism, when analyzing the schooling of mothers found that the average schooling was 10 years, which corresponds to the first grade of upper secondary education; and that 52.5% of the mothers had less than average schooling [16].
It can be added that schooling acts in a proportional way since by presenting a better schooling and level of instruction, a greater number of measures appear to avoid the presence of intestinal parasitism. Some research developed by Ares Maza [17][18][19][20][21], has shown that parents have significant direct or indirect influences on their children from very early ages. All this suggests that the role of the father in family education should be better reviewed due to the different position that he could occupy in certain socio-economic and cultural contexts.
Considering that this constitutes the first step to be able to raise the level of knowledge regarding the disease, making it possible for parents to define it and thus be able to talk about it with a solid foundation based on knowledge.
Similar results were in a study conducted with mothers of children from 0 to 4 years of age at the Corralillo office in the province of Guantanamo in 2007 [22].
The most effective measure in the prevention of Have you ever had intestinal parasites or do you know any of your friends who have ever been sick because of this?
Then and with all the desire to help you to increase your knowledge about it, we show you a series of questions that you must answer with all sincerity, so that later, the area doctor can help you clarify all your questions.
Thank you very much for your cooperation.
