The Associations of Body Mass Index, Body Image, Perceived Stress, and Mental Health among Female Nursing Students: A Cross-Sectional Study in Taiwan

Maintaining a healthy caloric intake and expenditure balance is challenging. The preliminary study examined (a) the associations of Body Mass Index (BMI), body image, perceived stress, mental health, dietary habits, and exercise participation among 310 female college nursing students and (b) the differences in these factors among BMI subgroups. The cutoffs for underweight, normal weight, overweight, and obesity were <18.5 kg/m(2), =18.5 but <23 kg/m(2), =23 but <25 kg/m(2), and =25 kg/m(2), respectively. The survey used Multidimensional Body-Self Relations Questionnaire-Appearance Scale, Perceived Stress Scale, and Chinese Health Questionnaire (CHQ). Because of a non-normal distribution, non-parametric statistics were used. The study found that BMI correlated with body image. The lower the BMI, the higher the satisfactory score the participants rated. BMI was irrelated to diet, exercise, stress, and mental health. The participants were unlikely to eat under stress and negative moods. The underweight group (17.1%) had the highest satisfactory score on their appearance evaluation. There was no difference between the overweight (14.2%) and obese (11.0%) groups. Meanwhile, the median of perceived stress was 18 and the prevalence of mental disturbance was 45.2% based on the CHQ. Underweight, overweight, obesity, high perceived stress, and poor mental health among nursing students warrant attention. Nurse educators should strengthen their coping strategies and provide support. A longitudinal study may consider incorporating coping strategies into the study design.

Automated summary

This preliminary study examined the associations between Body Mass Index (BMI), body image, perceived stress, mental health, dietary habits, and exercise participation among 310 female college nursing students. The study found that BMI correlated with body image, but not with diet, exercise, stress, and mental health. The underweight group had the highest satisfactory score on appearance evaluation, while there was no difference between the overweight and obese groups. Attention should be given to underweight, overweight, obesity, high perceived stress, and poor mental health among nursing students.
