Association Between Obesity and Self-Reported Depression Among Female University Students in the United States.

AIM: To determine the relationship between obesity and depression among female undergraduate students at Western Illinois University (WIU), Macomb, Illinois. METHODS: A cross-sectional study using self-reported questionnaires were conducted between August 15, 2019, and December 15, 2019. A cohort of 434 female undergraduate students was retrieved from the study. We determined the association between self-reported diagnosis of depression within the last year and body mass index (BMI) among female students. RESULTS: The prevalence of depression among female undergraduates at WIU was 33.2%. Obese and overweight female undergraduate students had a higher likelihood of being diagnosed with depression than students with normal BMI (reference), overweight (OR= 1.91; 95% CI 1.11-3.31), obese (OR= 2.20; 95% CI 1.30-3.80). Latino and black students were less likely to report depression than white students, Latino (OR=0.37 95% CI 0.15-0.92), and Black (OR= 0.40; 95% CI 0.18-0.86). There was also a positive association between chronic back pain and development of the diagnosis of depression, (OR=2.26; 95% CI 1.45-3.52). CONCLUSION: Depression among female undergraduate students is very common in the USA. Obese and overweight female students are more likely to be depressed than students with normal BMI. There is a need for urgent public health interventions to reduce the obesity rate among university students.
