Abstract

Objective:

To analyze health service utilization and associated factors among university students.

Methods:

This was a cross-sectional study conducted with a sample of 2,708 students at the Federal University of Pelotas between November 2017 and July 2018.

Results:

Of the 1,865 individuals included in the study, 55.8% used health services in the last 12 months, 39.3% used specialized services, and 22.6% used health centers; 45.9% used services funded by the Brazilian National Health System (SUS); 49.1% used health services for the purposes of prevention. There was greater use among females (prevalence ratio, PR=1.34 - 95%CI 1.23;1.46) and students with health needs (PR=1.51 - 95%CI 1.40;1.63). Greater association was found with SUS-funded services: primary health care center (83.0% [95%CI 77.3;87.5]), accident and emergency (81.3% [95%CI 73.2;87.5]) and urgent care center (83.6% [95%CI 76.2;89.0]).

Conclusion:

The analysis indicated that women and people with health needs use health services more and that the SUS is the main service provider.

Introduction

With effect from the 1988 Constitution, Brazilians have been guaranteed the universal right to public health care through the Brazilian National Health System (SUS). It is estimated that the SUS is the only form of access to health services for over 150 million people and, according to the 2013 National Health Survey, 95% of those who sought a SUS health service received care there.¹1.

Service utilization measurement enables an understanding of access to health care in general. As a positive expression of such access, service utilization measurement can impact the health of populations, preventing diseases from occurring, reducing mortality and increasing survival rates.²2.

http://bvsms.saude.gov.br/bvs/publicacoe... Health service utilization is influenced by a complex combination of factors, ranging from health needs, how services are perceived by service users and health workers, service availability and organization, to type of service funding. In addition, it can also vary according to individual service user characteristics, type of coverage and the service used.³3. Silva ZP, Ribeiro MCSA, Barata RB, Almeida MF.

Studies specifically dedicated to the population of young adults between 20 and 40 years old are rare in Brazil, despite the fact that this population requires comprehensive health care with emphasis on preventive actions.⁵5.

The objective of this study was to analyze health service utilization and associated factors among students at the Federal University of Pelotas, Rio Grande do Sul, Brazil.

Methods

This was a cross-sectional census-type study, with fresher students at the Federal University of Pelotas (UFPel), located in the municipality of Pelotas, in the first semester of 2017. The study was part of a UFPel Postgraduate Program in Epidemiology research consortium.¹¹11. Barros AJD, Menezes AMB, Santos IS, Assunção MC, Gigante D, Fassa AG, et al.

The city of Pelotas has approximately 342 million inhabitants and is located in the south of the state of Rio Grande do Sul, 250 km from its capital, Porto Alegre.¹²12. Instituto Brasileiro de Geografia e Estatística. Panorama das cidades brasileiras [Internet].. [Rio de Janeiro]: IBGE; 2018 [acesso 11 set. 2018]. Disponível em: Disponível em: https://cidades.ibge.gov.br/brasil/rs/pelotas/panorama
https://cidades.ibge.gov.br/brasil/rs/pe... UFPel offers in-class and online courses, and currently has 16 million students spread over the institution’s six campi: Capão do Leão Campus, Porto Campus, Center Campus, North Campus, Fragata Campus, and Anglo Campus. Eighty of its 96 courses are in-class and enrollment takes place in the second semester of each year.¹³13. Universidade Federal de Pelotas. Institucional: histórico [Internet]. [Pelotas]: UFPEL; c2021 [acesso 23 jan. 2021]. Disponível em: Disponível em: https://portal.ufpel.edu.br/historico/
https://portal.ufpel.edu.br/historico/...

All students 18 years old or more who started any of the 80 in-class courses at UFPel in the first semester of 2017 and remained enrolled in the second semester were considered eligible. In order to identify them, we consulted the official lists provided by UFPel's Chancellor’s office to find the disciplines of each course with the highest number of eligible students.

With regard to the variables, the outcome was considered to be health service utilization verified by asking the following question: In the last 12 months, have you used any health service in Pelotas or in any other city?

Health services were taken to be primary health care centers, outpatient clinics, psychosocial care centers, accident and emergency and other urgent care services, consulting rooms, hospitals and diagnostic and therapeutic support services.

With regard to the variables, the number of contacts with health services in the last twelve months, the type of service stated in the definition of the study outcome - and the type of funding of the last health service used (SUS; outsourced to SUS; private) were obtained from those who used health services. In this subgroup, the reasons for using health services were investigated by asking the following question: Why did you use the last health service you attended?

The answer options were categorized as follows: prevention; follow-up; accidents or injuries; psychological problems; and dental problems. The ‘prevention’ category included investigation of problems, vaccination, preventive examination and nutritional guidance; ‘follow-up’ included rehabilitation; and ‘accidents or injuries’ included trauma treatment and having been submitted to surgery.

The independent variables selected were:

A digital questionnaire was prepared for this survey using the Research Electronic Data Capture (REDCap) application,¹⁵15. National Institutes of Health. Research Electronic Data Capture: REDCap. [software]. [local desconhecido: REDCap; 2004 [acesso 5 set. 2017]. Disponível em: Disponível em: https://projectredcap.org/software/
https://projectredcap.org/software/... answered anonymously on tablets. The instrument was structured in two blocks. The first block consisted of general information related to the undergraduate course and the student's view of the university, demographic and socioeconomic characteristics, religious practice, occupation and social benefits. The second block consisted of questions related to health service utilization. The answers to the questionnaires that were filled in using tablets were transferred to a single database, with automatic checking of the amplitude and consistency of the variables. Fifty-one students opted to fill in printed questionnaires and their answers were input twice to the REDCap application platform in order to include them in the final database.

Data collection took place between November 2017 and July 2018, except for the summer recess in January. Master's degree students were trained to provide a standardized explanation of the study and to conduct the interviews which were held in classrooms. After meeting with the course teaching groups, times were scheduled with the teachers to let students leave their classes for a period of 40 to 50 minutes in order to answer the questionnaire. Prior to this process, a pilot study was carried out with a sub-sample at the same institution to test their understanding of the instrument and its suitability for the target population.

In order to measure prevalence of health service utilization, the sample size was calculated based on 60% prevalence, a 95% confidence level and acceptable error of two percentage points. This required 1,304 individuals for the sample. With regard to analysis of association, we adopted a 5% significance level and 80% statistical power, 8.3% prevalence of the outcome in those who had no health needs, a minimum prevalence ratio of 1.8, and a 1:6 exposure ratio. We added 10% for losses and refusals, resulting in a sample size of 897 individuals to be interviewed.

“Losses” were considered to be students not found during the data collection period, while "refusals" were those who refused to participate in the study after it had been explained in the classroom. To minimize losses and refusals, we made at least three attempts to visit the classes, at different times, until we achieved 70% of respondents. The questionnaire was self-administered in order to ensure the participants' anonymity.

The complete database was exported to the statistical package Stata version 14.2 for the analyses to be performed. We used descriptive analysis to characterize the sample, and crude and multivariable analysis to investigate the associations. A 5% significance level was used in all hypothesis tests. In the descriptive analysis, calculations of proportions and 95% confidence intervals (95%CI) were performed for the categorical variables.

The tests applied in the crude analyses were (i) Pearson's chi-square and (ii) linear trend when suggested. In the multivariate analysis, the 'sex', 'age' and 'health need' variables were adjusted for each other, adopting a 20% significance level. Effect measurements were estimated using Poisson regression with robust variance, which provided adjusted prevalence ratios (PR) and respective 95%CI. In the adjusted analysis, the final model to take confounding variables into account was created from an association matrix, in which all exposure variables were tested with the outcome and also between each other, using a p-value of less than 0.20.

The study project had no conflict of interest and was approved by the Federal University of Pelotas Faculty of Medicine Research Ethics Committee, as per Opinion No. 2.352.451, issued on October 27, 2017 (Certificate of Submission for Ethical Appraisal No. 79250317.0.0000.5317). The questionnaire was only administered with students who agreed to participate in the study and who signed the Informed Consent form.

Results

Out of 2,708 eligible students, 1,865 students who started at UFPel in the first semester of 2017 (69%) were interviewed (Figure 1). Losses and refusals in the survey represented 31.1% of those eligible. Among the total number of respondents (n=1,865), 52.8% were male, aged 23 years and older (46.7%). Regarding the respondents: 45.9% were from Pelotas; 54.8% were female; 56.3% were between 18 and 20 years old; 72.0% reported being of white race/skin color; 44.2% were in economic category B and 36.5% in category C; 32.1% of the students had a mother with complete high school education; 50.4% lived with parents or relatives; and 35.1% reported having perceived some health need that prevented them from performing their usual activities at some point in the last three months (Table 1).

Prevalence of health service utilization in the last 12 months was 55.8% (95%CI 53.5;58.1). In the crude analysis, association was found between the outcome and the 'gender' and 'health need' variables. The probability of female students using health services was 1.34 (95%CI 1.23;1.46), compared to male students; while the probability of students with health needs using them was 1.51 (95%CI 1.40;1.63), compared to those who reported having no health needs (Table 1).

After adjusting for 'age' and 'health needs', health service utilization was higher among females (PR=1.27 - 95%CI 1.16;1.38) than among males. Service utilization by students with health needs was also higher (PR=1.47 - 95%CI 1.36;1.59) compared to those who did not report having health needs, after controlling for 'sex' and 'age' (Table 2).

Among those who did use health services, 40.7% had only one contact over 12 months, and 34.2% had three or more contacts. Using specialized care services (outpatient clinics, consulting rooms, or psychosocial care centers) was mentioned by 39.3% of the students. Regarding the type of funding of the services used by the students, the most recurrent was the SUS (45.9%), while private services were used the least (19.5%). Prevention accounted for almost half the use of the last health service attended (49.1%), followed by health problem follow-up (37.4%) (Table 3).

Analysis of the main reasons for using a service in the last 12 months, according to type of funding (Figure 2), revealed a statistically significant difference. Taking this sub-sample as a whole, the SUS was the most commonly reported type of funding, accounting for 45.9% (95%CI 42.8;49.0). Individuals having follow-up used SUS outsourced services more (41.7% - 95%CI 36.7;46.9), while the private sector had the highest share among those who reported using services for psychological problems (47.8% - 95%CI 33.4;62.6) and dental problems (44.0% - 95%CI 25.2;64.7).

A statistical difference was also found when analyzing the type of service used in the last visit and the type of funding (Figure 3). Again, SUS service coverage was the type of funding most used (45.9% - 95%CI 42.8;49.0). This source of funding accounted for a large share of primary health care center services (39.9% - 95%CI 35.4;44.6), urgent care (25.4% - 95%CI 21.5;29.7), and emergency care (21.8% - 95%CI 18.1;25.9). With regard to use of SUS outsourced services, the highest proportions corresponded to specialized care services (63.6% - 95%CI 58.2;68.7) and diagnostic and therapeutic support services (19.8% - 95%CI 15.8;24.5).

Discussion

This study found that slightly more than half of the UFPel undergraduate students interviewed had used health services in the last 12 months. Their demand for health services was therefore frequent. In comparison to males, females used these services more. With regard to greater demand among people with health needs, it is possible to assume that they mainly used prevention services. This conclusion is reinforced by the fact that approximately one in two students reported using health services for preventive reasons. The SUS was the most reported funding type among the university students who used health services.

The study had a high proportion of losses, and it is possible that these students could have greater health needs and therefore have greater demand for health services. Their health needs may be why the frequency of their class attendance was lower, resulting in their being lost to the study. In this sense, the frequency of university students surveyed during classes may not fully reflect the demand and profile of health service utilization by this target population of young adults (selection bias). Another limitation of the study lies in the self-administered questionnaire interview format, as the answers to the questions are anonymous and are therefore likely to induce analyses and conclusions influenced by response bias. We encountered difficulties in precisely composing the response categories depending on the 12-month recall period, in addition to the possibility of misunderstanding by interviewees - even after a pilot study - leading to possible measurement problems. Nevertheless, the format of some of the categories was maintained, with the aim of their being able to be compared with other studies.

Health service utilization was lower than that found by a study conducted in 2011, also in Pelotas, with young adults from the 1982 birth cohort, among whom there was 72% prevalence of health service appointments.⁸8. Dias-da-Costa JS, Gigante DP, Horta BL, Barros FC, Victora CG. Utilização de serviços de saúde por adultos da coorte de nascimentos de 1982 a 2004-5, Pelotas, RS.

http://dx.doi.org/10.15090/S0034-8910200... In turn, the 2013 National Health Survey found prevalence close to 11% for seeking and using health services in the two weeks prior to the interview.¹1.

https://biblioteca.ibge.gov.br/visualiza... One of the reasons for this difference in the prevalence rate we found and the prevalence rate found by the 2013 National Health Survey lies in the recall periods being of different length. In addition, according to data from the 2009 National Household Sample Survey, in the Brazil there are considerable differences in access to higher education depending on family income: only around 5% of the poorest go to university compared to 60% of the wealthiest.¹⁶16. Instituto Brasileiro de Geografia e Estatística. Pesquisa nacional por amostra de domicílios: síntese de indicadores [Internet]. Rio de Janeiro: IBGE; 2009 [acesso 23 abr. 2018]; Disponível em: Disponível em: https://biblioteca.ibge.gov.br/visualizacao/livros/liv45767.pdf
https://biblioteca.ibge.gov.br/visualiza... This reality may explain the health service utilization profile found in our sample.

Two out of five university students at UFPel used at least one health service in the last tewleve months, while a study conducted at the University of Pretoria, South Africa, in 2007, found average prevalence of 12.5% of health service use by the university population at that South African institution over five years.¹⁷17. van Papendorp HD, Coetzee M, Koorts AM. The student health services at the University of Pretoria from 2000 to 2005. Health SA. 2007;12(1):48-54. doi: http://doi.org/10.4102/hsag.v12i1.243.
https://doi.org/http://doi.org/10.4102/h... These results indicate that young adults, not only in Brazil, rarely seek and use health services, even though they represent a key opportunity for education and adoption - or maintenance - of healthy lifestyles, provided by qualified multiprofessional care. Even when it comes to the use of any type of health service and not only primary health care centers, this finding is in agreement with that found by the second edition of the 2012 National School Health Survey: in Brazilian state capitals, 52.9% of students used a primary health care center only once or twice in the last twelve months.¹⁸18.

Among the sociodemographic and health factors investigated, the person’s sex and health needs were associated with health service utilization. Regarding sex, a study conducted in 2011 in Brazil showed that women have been standing out as the main service users.³3. Silva ZP, Ribeiro MCSA, Barata RB, Almeida MF.

https://doi.org/http://dx.doi.org/10.512... In our survey in Pelotas, aside from exclusively female gynecological and reproductive reasons - investigation or screening for cervical cancer and human papillomavirus infection - and prenatal, labor and puerperium follow-up, women reported having more health needs. They also reported greater utilization of services related to mental health problems compared to men, possibly due to their greater ease in perceiving and expressing their emotional difficulties. Compared to women, men accounted for highest health service utilization due to accidents and injuries. A parallel can be drawn here with deaths from external causes in Brazil: according to Ministry of Health data for the period from 1996 to 2018, deaths from external causes are, on average, 4.9 times higher among males when compared to females.¹⁹19.

Approximately two out of five university students used specialized services, and for about a quarter of them the primary health care center was where they last received care in the 12 months prior to the survey. The relationship between this finding and another variable - the use of prevention services, the most prevalent reason - may explain this demand for specialized care. According to the study conducted by Dias-da-Costa et al., the main reason for the use of health services by young adults was the presence of diseases, although the authors did not collect data on the use of preventive services.⁸8.

http://dx.doi.org/10.15090/S0034-8910200... Another study conducted in Pelotas, this time in 2012 with an adolescent population, found prevalence of consulting room and primary health care center use similar to that found in our study.¹⁰10.

https://doi.org/http://dx.doi.org/10.512... These results suggest that university students use primary and secondary health care services more.

The findings of this study are in agreement with those of other studies, revealing the SUS as the main source of health service funding, followed by outsourced Supplementary Health services.³3.

After investigating association between type of funding and the 'services used' and 'reason' variables for most recent use of a health service, the SUS was found to have a greater share in the results of both analyses. Even with the precariousness and underfunding of public health services, these were still the main providers of primary health care, as the entry point to the SUS.²⁰20. Reis AAC, Sóter APM, Furtado LAC, Pereira SSS. Tudo a temer: financiamento, relação público e privado e o futuro do SUS. Saude Debate. 2016;40:122-35. doi: http://doi.org/10.1590/0103-11042016S11.
https://doi.org/http://doi.org/10.1590/0... The differences found in the type or nature of funding of the service used can be attributed to the profile of service supply. Private services are more focused on health problems, while outsourced services are more focused on general consultations in certain specialties.

The SUS provides health care that ranges from preventive measures to more complex services, based on comprehensive care, including between different levels of service complexity, despite it being recognized that there are problems in accessing the system at the regional and/or local level.

Use of Public Health services is higher not only among young adults. The 2012 study with adolescents in the city of Pelotas found a prevalence rate of 52.1% for SUS service utilization.¹⁰10.

Another study conducted in Brazil in 2014, with residents in the urban area of municipalities in the five major Brazilian regions, identified that 53.6% of individuals seen by physicians in the last three months used services funded by the SUS.²¹21.

We conclude that this research, carried out with a population of students from the UFPel identified health service utilization associated with females and people with health needs. The majority of those who used these services in the last twelve months mentioned having sought health care for preventive reasons, mostly specialized care services, funded by the Brazilian National Health System. It is therefore important to adopt specific strategies and actions for disease prevention among the population of university students.
