Background: Unhealthy lifestyle practices and physical inactivity may lead to overweight, obesity, and other noncommunicable diseases. For an undergraduate medical student, the 1st year is a dynamic transitional period of development and growth. An educational intervention if planned at this crucial stage may help to improve the health status of the students. The present study was therefore designed to evaluate the impact of a multidisciplinary educational intervention in improving the body mass index (BMI) and waist–hip ratio among the undergraduate medical students. Materials and Methods: Hundred and seventy-seven 1st-year undergraduate medical students (74 males and 103 females) participated in the study. A multidisciplinary educational intervention was provided to promote a healthy lifestyle. The parameters such as BMI and waist–hip ratio were measured both in the baseline and 3 months after the educational intervention. The BMI calculated was used to categorize the student population into four groups: normal, overweight, obese, and underweight. Results: After the educational intervention, a significant difference was observed in the BMI, the hip circumference, and the waist/hip ratio (<0.001). The waist circumference although showed a decrease, the finding, however, was not significant statistically. Further, the obesity among the student population also observed a marked reduction. The comparison of the parameters among the male and the female students did not show any statistical difference. Conclusion: A multidisciplinary educational intervention on healthy lifestyle practices aids to enhance the health status of an individual by improving the BMI and waist/hip ratio. It would further contribute to a medical student's role in promoting a healthy lifestyle.

| Introduction|| |
Healthy lifestyle in adults depends on the early acceptance of healthy habits, whereas unhealthy lifestyles among youths are powerfully associated with unhealthy habits in adulthood., Unhealthy lifestyle behaviors such as unbalanced diet, lack of physical activity, stress, and smoking are significant risk factors that lead to conditions such as overweight, obesity and noncommunicable diseases. Obesity is one of the emerging driving forces behind the cardiometabolic risk in the younger population. It is a major predisposing factor for developing hypertension, ischemic heart disease, and noninsulin-dependent diabetes mellitus.,,,
For an undergraduate medical student, the 1st year is a critical time. It is a dynamic transitional period of development and growth that bridges childhood to adulthood. Studies have revealed that many students at this stage exhibit physical inactivity, unhealthy dietary practices, insufficient sleep, and rest, which might affect their present and subsequent health status.,,
Medical students are future health-care professionals who are invested with the responsibility of restoring health and well-being in the society. They should be role models to the public. Therefore, it is essential to improve their health-promoting lifestyle behaviors right from their initial days in a medical school.
Health education in the university is regarded as an ideal means for teaching healthy lifestyles. It is because the students at this stage are in a unique step of knowledge absorption and personality shaping.
Our previously published reports had focused on the observations of lifestyle practices among medical students. It revealed that health responsibility, physical activity, nutrition, spiritual growth, interpersonal relations, and stress management play a vital role in influencing the health status of an individual. It further encouraged us to plan an appropriate educational intervention to address these factors.
Therefore, the present study was designed to evaluate the health status, i.e., body mass index (BMI) and waist–hip ratio in the undergraduate medical students before and after providing a multidisciplinary educational intervention.
| Materials and Methods|| |
The present observational study was conducted on the 1st-year undergraduate medical students. The convenient sampling method was employed to recruit the participants. After obtaining the informed consent, 177 students (74 males and 103 females) were included in the study. The students who refused to give informed consent or were absent during the study were excluded from the study. The study was approved by the Institutional Ethics Committee (325/2015).
Before the educational intervention, the height, weight, and waist and hip circumferences were measured. The BMI and waist–hip ratio were calculated using the standard formula. The students were then categorized from underweight to obese based on the standard classifications of BMI.
The educational intervention was designed in the form of lectures, demonstrations, role play, and video presentations involving different disciplines such as medicine, yoga, physiotherapy, dietetics, and applied nutrition [Figure 1].

The interactive sessions covered topics such as general guidelines for a healthy life, balanced diet and nutrition, importance of regular exercises, health hazards, awareness about consulting a physician, and importance of yoga and meditation for a healthy life.
Demonstration of yoga was also conducted to encourage the students to implement the same. It was carried out in four interactive sessions of 2 h each for 2 months, i.e., November and December 2015.
Three months after the completion of the intervention, the same measurements, i.e., height, weight, and waist and hip circumferences were measured, and the BMI and waist–hip ratio were calculated.
The data were recorded and analyzed using SPSS version 16 (SPSS Inc., Chicago, IL). The BMI, waist and hip circumferences, and waist/hip ratio before and after the educational intervention were compared using a Paired t-test. The comparison between the male and female students was conducted using independent sample t-test. P ≤ 0.05 was considered statistically significant.
| Results|| |
Hundred and seventy-seven 1st-year undergraduate medical students (74 males and 103 females) participated in the study. The pre- and postintervention findings of BMI, waist circumference, hip circumference, and waist/hip ratio were tabulated [Table 1]. Among them, the BMI, hip circumference, and waist/hip ratio when compared showed the statistically significant difference (<0.001), while the waist circumference did not show any significant difference. The difference in the BMI and the waist/hip ratio among the male and the female students when compared did not show any statistical difference. The BMI calculated was also used to categorize the student population into four groups: normal, overweight, obese, and underweight. The individual with a healthy BMI found a rise after the educational intervention (44.6%). Further, the obesity among the student population also observed a marked reduction (29.8%) [Figure 2].

| Discussion|| |
Previous studies on healthy lifestyles reveal that majority of the students are less frequently involved in health-promoting behaviors,, and show unhealthy lifestyle practices.,
These unhealthy practices and their consequences extend into adulthood, jeopardizing individuals' health status in later life.
If these methods are identified and changed at an early stage, then the effects of health risk factors among adults are avoidable.
Previous studies have indicated that healthy lifestyle practices help to minimize the occurrence of disease and mortality rates.,,,
Therefore, it is essential to increase healthy lifestyle behaviors among young people.
The educational intervention planned in the present study was shown to improve the health status of the undergraduate medical students involved. The BMI, hip circumference, and waist/hip ratio measured before and after the intervention showed a statistically significant difference. Further, the categorized BMI indicated a gradual increase in the population of individuals with healthy BMI and decreased in the obesity after the educational intervention. However, the people with overweight and underweight found a rise postintervention. It may be due to the reduction in the weight and their shift into the category of lower BMI.
Studies conducted on medical students at a university in Northwestern Saudi Arabia indicated that 34.5% of the students were overweight and 10.3% were obese.
In addition, in a study estimating the occurrence of overweight and obesity among the Malaysian medical students, it was identified that 14.8%, 15.9%, and 5.2% were overweight, preobese, and obese, respectively.
These were cross-sectional studies, and the findings were recorded without involving any educational intervention.
In the present study, before the educational intervention, it was identified that 43.5%, 15.8%, 37.9%, and 1.1% were normal, overweight, obese, and underweight, respectively. After the intervention, the findings were 44.6%, 19.8%, 29.8%, and 4.5% for normal, overweight, obese, and underweight, respectively.
Lifestyle behaviors in younger age may have an impact on lifestyle-related disorders in the future.
The health hazards among adults can be prevented from identifying the practices and rectifying them at an early stage.
Increasing the awareness of healthy lifestyle habits among the youth is therefore essential. The present study agrees with the same.
Studies have also shown that implementation of interventions at worksites caused substantial mean weight loss and improved cardiometabolic risk factors.
Similar observations were made in the present study, wherein the BMI and waist–hip ratio showed a significant improvement followed by the implementation of the educational intervention in undergraduate medical students.
In a study carried out by Hsiao et al., a significant increase was observed in the total and subscale score averages of healthy lifestyle behaviors.
Furthermore, Yeh et al. reported positive changes in the lifestyle habits of students after providing an educational intervention.
A systematic review carried out to determine the causative factors for overweight and obesity identified physical inactivity, stress, inadequate sleep, and consumption of junk food as significant contributors.
The educational intervention planned in the present study targeted on these factors and created an awareness of them. It further helped to improve the health status of the individual.
Studies by Can et al. suggested that all aspects of healthy lifestyle showed better results among the medical students than the students of a nonmedical curriculum.
The better results may be attributed to the medical curriculum that instigates the students to adopt a healthy lifestyle. Difficulty in adjusting to a new teaching–learning environment and the type of food available in the campus may be some of the confounding factors for the study.
Medical students are the future health professionals, and with a sound, scientific base and are indebted to serve the community. Sensitizing the students early in their courses will not only facilitate the better adoption of healthy lifestyles among themselves but will also play a significant role in influencing masses to adopt healthy lifestyles in future years.
| Conclusion|| |
Education about lifestyle practice and its related health hazards is crucial for leading a healthy life. The present study endorses it and states that a multidisciplinary educational intervention helps to enhance the health status of an individual by improving the BMI and waist/hip ratio. It would further contribute to a medical student's role in promoting a healthy lifestyle.
