Introducción
One of the greatest challenges facing global public health is the prevention of non-communicable diseases (NCDs), also known as chronic diseases, such as diabetes, cardiovascular diseases, cancer, or chronic respiratory diseases, which can become complicated and lead to disability in daily functioning and, in the long term, death. These NCDs develop due to the presence of various metabolic, behavioral, and environmental risk factors

.
NCDs account for 70% of mortality worldwide among the 30-69 age group. However, it has been observed that 80% of these deaths occur prematurely, especially in low- and middle-income countries. In Latin America, the prevalence of NCDs increased from 77.4% in the year 2000 to 80.7% in 2016, with a higher prevalence in women. Among the countries with an increase in this prevalence is Peru

.
Four main factors have been evidenced in the development of NCDs: tobacco use, unhealthy diet, physical inactivity, and excessive alcohol consumption. These are part of a person's lifestyle and are modifiable behaviors, as they are influenced by economic, social, cultural, and psychological situations. The influence of an inadequate lifestyle (IAL) is present in 99% of obesity cases, followed by 91% for diabetes mellitus cases, and thirdly, 82% of heart disease cases

.
The transition between adolescence and adulthood is a period of lifestyle change and personal development that can influence dietary behavior due to changes in the academic environment or economic situation. These factors show a strong association with diet in this age range
7

.
Undergraduate university students are a population susceptible to presenting these risk factors and are in a period of their lives where they are still constantly changing their habits, which can affect their health benefits. The stress that accompanies this phase of life leads them to adopt an IAL, mainly characterized by poor nutrition, physical inactivity, and the use of legal and illegal drugs. Therefore, each behavior is voluntary and influenced by various sociodemographic factors
9
10
.
Thus, concern for health promotion takes on greater interest among health science students, not only for themselves but also for the role they play and will continue to play throughout their professional careers. They provide the necessary means to modify behaviors that endanger their health and that of their patients by managing external and internal factors to achieve an adequate or healthy lifestyle (AL)
10
12
.
For this reason, this study investigated whether there are factors associated with the development of an IAL among medical students. Additionally, the most frequently altered dimensions among students with IAL were identified.
METHODS
Study Design and Area
A cross-sectional and analytical study was conducted through a survey of students enrolled in the 1st to 12th cycles of the School of Human Medicine at the Universidad Privada Antenor Orrego in the city of Trujillo, Peru, during the academic semester of the first half of 2023
Population and Sample
The surveys of students who met the following criteria were included: aged 18 years or older, who agreed to participate by providing informed consent. Those with incomplete data or an incomplete FANTASTIC questionnaire were excluded. A non-probabilistic sampling method was used.
Variables and Instruments
It was determined whether the variables such as age, sex, marital status, employment activity, family responsibilities, study cycle, and place of residence were factors associated with an inadequate lifestyle (IAL) among medical students.
Lifestyle was determined using the FANTASTIC questionnaire, which consists of 30 items distributed across 10 dimensions: family and friends' core, physical activity and associations, nutritional habits, tobacco use, alcohol or other drug consumption, sleep condition and stress levels, type of work and personality traits, presence of introspection, health control situation, and sexual and other behaviors. Each dimension was composed of 3 items, and each item could score between 0 and 2 points.
Most items were answered according to a Likert scale. The total score from the 30 items was multiplied by 2 to obtain the final score, with a range between 0 and 120 points. This score was classified into five categories summarizing the lifestyle of the student being evaluated: 0 to 46: At risk, 47 to 72: Low, could improve, 73 to 84: Doing well, 85 to 102: Doing right, 103 to 120: Fantastic lifestyle.
IAL was considered in the categories "At risk" and "Low, could improve," whereas an adequate lifestyle was considered in the categories "Doing well," "Doing right," and "Fantastic lifestyle."
This questionnaire has been adapted to our Spanish language and validated in various Latin American countries, including ours, with very good reliability results in university students
13
.
In our country, the FANTASTIC questionnaire has been applied to healthcare workers. Villar et al. analyzed the reliability of this instrument and obtained a reliability score using Cronbach's alpha analysis of 0.778
14
.
Secondarily, the dimensions of the FANTASTIC questionnaire that were most frequently associated with IAL were identified.
Procedures
The research was approved by the Research and Ethics Unit of the School of Human Medicine at the Universidad Privada Antenor Orrego. A survey was then sent via a Google Forms URL to students through their institutional email, which included informed consent. The survey consisted of two parts: the first part involved collecting sociodemographic variables and the factors to be investigated, and the second part was the FANTASTIC questionnaire
14
, which was the instrument used to identify and assess lifestyle.
Statistical Analysis
For data analysis, SPSS V.26 software was used. Descriptive statistics were applied, with frequencies and proportions used for qualitative variables, and means and standard deviations (SD) calculated for quantitative variables. Prevalence Ratio (PR) was calculated to determine the association of the proposed factors with IAL, considering significance at p < 0,05.
Ethical Aspects
The research was approved by the Research and Ethics Unit of the School of Human Medicine at the Universidad Privada Antenor Orrego (Resolution No. 0130-2022-FMEHU-UPAO). All participants provided informed consent and responded anonymously from a computer or electronic device with internet access.
RESULTS
A total of 258 students participated; their average age was 20.7 ± 3.5 years, 66.3% were female, 97.3% were single, 87.6% did not work while studying, 86.8% did not have any family members dependent on them, 78.7% lived in an urban area, and 18.6% were in their first study cycle (Table 1).
A total of 112 students (43.4%) exhibited an inadequate lifestyle (IAL), while the remaining 146 (56.6%) had an adequate lifestyle (AL) (Table 2). In Table 2, it is observed that those with IAL had an average age of 20.7 ± 3.1 years, 72.3% were female, 98.2% were single, 89.3% did not work while studying, 86.6% did not have any family members dependent on them, 82.1% lived in an urban area, and 16.1% were in their first study cycle. On the other hand, students with AL had an average age of 20.7 ± 3.8 years, 61.6% were female, 96.6% were single, 86.3% did not work while studying, 87.0% did not have any family members dependent on them, 76% lived in an urban area, and 20.5% were in their first study cycle.
The most prevalent characteristics in participants with IAL were being female, single, not working while studying, not having a dependent family member, residing in urban areas, and being students in the 3rd to 10th study cycles. When the bivariate analysis of the studied factors and lifestyle type was performed, no significant difference was found in the factors investigated (Table 2).
Additionally, multivariate analysis was performed, where the crude prevalence ratio (PRc) and adjusted prevalence ratio (PRa) were determined for all variables considered as factors associated with an inadequate lifestyle in medical students. In the results of the analysis, no significant association was found (Table 3).
In Table 4, the mean score with its standard deviation of the 10 dimensions that make up the FANTASTIC questionnaire is presented; the scores ranged between 2.84 and 5.04. It was found that the four dimensions with the lowest scores were physical activity (3.02 ± 1.53 points), sleep and stress (3.00 ± 1.48 points), introspection (3.01 ± 1.50 points), and health control (2.84 ± 1.55 points).
In Table 5, the frequency of students' responses to each of the items that make up the four dimensions with the lowest scores in the FANTASTIC questionnaire is shown.
DISCUSSION
Female students were the majority of participants in this survey to evaluate lifestyle. Although the proportion of female and male students was 66.3% and 33.7%, respectively, these findings were similar to those reported by Ramírez-Vélez et al.
15
, Jiménez and Hernández
16
, Canova-Barrios
17
, Cáceres and Morales
18
and Silva et al.
19
, where female participants predominated. However, this differs from the findings of Pacheco et al.
20
, Alzahrani et al.
21
and Montenegro and Ruiz
22
, where the majority of participants were male.
Female students were more prevalent in having IAL, something also described by Alzahrani et al.
21
, where women showed inadequate lifestyle scores. However, this contrasts with what was reported by Cáceres and Morales
18
, Montenegro and Ruiz
22
and Fang et al.
23
, where females exhibited better lifestyle habits compared to males.
On the other hand, gender has been cited by other authors as a determinant of lifestyle behaviors that promote health
23
,
24
. In fact, many social practices are gender-typed in society, and sports are often considered a male-dominated domain where male students tend to spend their free time on sports activities, while female students prefer to spend this time with family
21
. However, some unhealthy behaviors are also associated with males, such as distancing from family, tobacco, and alcohol consumption
23
.
Some studies have established that socioeconomic status is associated with healthy practices
25
,
26
. However, within university life, this factor could present both situations; higher income may encourage students to adopt the active social life of this particular environment, but it may also provide easy access to the negative aspects of university life, such as physical inactivity
23
,
27
.
Students aged 25 or younger had the highest prevalence of IAL, a finding similar to what was reported by Montenegro and Ruíz
22
, whose study indicated that those under 26 years of age showed very poor or average lifestyles. This differs from what was reported by Fang et al.
23
, who noted that, as participants' age increased, the dimensions of family/friends, tobacco, and alcohol were associated with IAL.
The marital status with the highest prevalence of IAL was found among single students (98.2% versus 96.6% of those with AL), a finding opposite to that found by Montenegro and Ruiz
22
and Shekhar et al.
27
, where those who were married had a higher prevalence of AL.
Students who dedicated themselves solely to studying mostly had IAL, a finding similar to what was reported by Montenegro and Ruíz
22
. Residing in an urban area had a higher frequency of IAL compared to semi-urban and rural areas, a result similar to what was reported by Shekhar et al.
27
.
The academic cycles where IAL was most prevalent were those between the third and tenth cycles, similar to what was reported by Alzahrani et al.
21
, where IAL was found among students in the fifth and sixth cycles, particularly concerning stress management, and by Fang et al.
23
, who determined that students in the sixth, seventh, and eighth cycles had IAL due to increased tobacco use. Our findings could be related to the fact that, during intermediate academic semesters, most students' physical activity decreases, adequate sleep hours decrease, and stress increases. However, stress management improves with age, and introspection and health control are less managed at younger ages and with less medical education.
The academic cycle represents another factor that can influence lifestyle. In fact, it has been shown that stress management improves with age and experience
23
Additionally, education and training have proven effective in raising awareness about improving lifestyle among students. Studies conducted among medical students have also shown that the more they practice healthy behaviors, the more committed they are to educating patients about health-promoting behaviors
24
.
In the present study, the average scores of the dimensions in the FANTASTIC questionnaire ranged between 2.84 and 5.04, similar to what was reported by Montenegro and Ruíz
22
, and different from what was found by Canova-Barrios
17
where the dimension scores did not exceed two points.
Our study found no association between the proposed sociodemographic and family factors and IAL among students from the School of Human Medicine. These findings are similar to those reported by Alzahrani et al.
21
and Montenegro y Ruíz
22
, who also did not find sociodemographic factors associated with the lifestyles of medical students.
Similarly, in this study, the average scores of the 10 dimensions of the FANTASTIC questionnaire were determined to identify which had the lowest scores among participants with an inadequate lifestyle (IAL) (Table 4). Additionally, the responses to the items in the 4 dimensions with the lowest scores were broken down, providing an opportunity to specifically strengthen these areas (Table 5). The identified dimensions were health control, sleep and stress, introspection, and physical activity, the latter being frequently reported in previous studies of similar populations
16
17
22
26
28
29
.
Meanwhile, the dimensions least associated with IAL, because they obtained the highest scores, were those related to alcohol consumption, tobacco use, other behaviors, and family and friends. This differs from what has been reported by other researchers, where alcohol and tobacco consumption were frequently associated with IAL among students
15
16
22
.
However, it is similar to what was described by Cáceres and Morales
18
and Martins et al.
19
.
The COVID-19 pandemic caused university classes to be held virtually from 2020 to 2022 due to the restriction on free movement until the population was vaccinated against SARS-CoV-2. In our country, classes were made mandatory in person starting in 2023, which meant that the participating population was exposed to additional factors related to suboptimal physical activity, inadequate nutrition, and stress. Martins et al.
19
conducted a study during the COVID-19 pandemic at a public university in Brazil, finding that 42.6% of the 61 medical students had an IAL, and the predominantly compromised domains were sleep, nutrition, stress, and physical activity. This contrasts with what was reported by Cáceres and Morales
18
, who found that in 72 medical students from Adventist public and private universities in Chile, Argentina, and Bolivia, 4.2% of participants had IAL, and in these students, the predominantly compromised domains were nutrition, health control, and physical activity; it is important to mention that 61.1% of the students identified as non-omnivorous diet consumers.
The identification of factors associated with IAL and the predominantly compromised domains in university students has led to interventions focused on physical activity, establishing dietary intake guidelines for better results, and reducing the risk of developing non-communicable diseases (NCDs) in the long term. Higher education institutions are an appropriate setting to begin promoting healthy and adequate lifestyle practices among their students
30
32
Among the limitations of this study are those inherent in a cross-sectional design, where a cause-effect relationship cannot be established, as well as the reliance on participants' memory to answer the questionnaire. The research was conducted at a single private university, which limits the generalization of our results. The sample size, the studied association factors, as well as the use of a non-probabilistic convenience sampling method may have introduced biases that could be controlled in future studies.

IAL: Inadequate lifestyle. AL: Adequate lifestyle. n: number of participants.
Conclusion
Age, gender, marital status, employment activity, having family responsibilities, study cycle, and place of residence were not factors associated with an inadequate lifestyle (IAL) among students of the School of Medicine at the Universidad Privada Antenor Orrego. The most prevalent dimensions in students with IAL were health control, sleep and stress, introspection, and physical activity.
