Body mass index and healthy lifestyle practices among Peruvian university students: a comparative study among academic discipline

Background

Excess body weight and an unhealthy lifestyle are a risk factor for noncommunicable diseases. University students are susceptible to unhealthy habits and obesity. This study compared body mass index (BMI) and healthy lifestyle practices among university students from four academic disciplines: Health Sciences, Business Sciences, Human Sciences and Education, and Engineering/Architecture.

Methods

A cross-sectional study was carried out using a sample of 6,642 university students selected by non-probability convenience sampling. The Diet and Healthy Lifestyle Scale (DEVS), the Peruvian validation of the Vegetarian Lifestyle Index (VLI), was used to assess healthy lifestyle practices.

Results

Students in the areas of Business Sciences and Engineering/Architecture had a higher BMI than their peers in Health Sciences (B = 0.35, 95% CI: 0.15-0.56 and 0.32, 95% CI: 0.13-0.52; p = 0.001). Additionally, these students tended to adopt less healthy lifestyle (B = -0.11, 95% CI: -0.20 to -0.01 and -0.09, 95% CI: -0.18 to -0.00; p < 0.05) compared to those in Health Sciences.

Conclusion

Although students of Health Sciences and Human Sciences and Education exhibited healthy lifestyle patterns, there is a clear need to improve eating and living habits in general among the university population to mitigate the risk factors associated with non-communicable diseases.

Perceptions of Teachers in Training on Water Issues and Their Relationship to the SDGs

Water conservation is essential for any activity, as well as for the survival of both human and other living beings. It is commonly associated with access to clean water and sanitation, or even to unsustainable production and consumption, or sustainable cities and communities. However, there is increasing awareness of emerging issues related to water resources and their impact or relationship with other issues, such as climate change, access to food, health and well-being, or biodiversity (marine and terrestrial). Therefore, this study is aimed at understanding the perception of students of the Degrees in Early Childhood Education and Primary Education concerning water issues and their relationship Sustainable Development Goals (SDGs; number 2,3,6,11,12,13,14 and 15) in a coastal urban context. The study used a qualitative design, in which 59 student teachers were interviewed. The instrument was validated by 12 experts. The content analysis indicates that student teachers understand that there is an environmental problem in relation to water caused by human behaviour, and that its effects have an impact on other areas that are related to the SDGs included in the 2030 Agenda.
