Is there a link between BMI and depressive symptomatology, risky consumption of alcohol and anxious symptomatology? Study in a sample of university students

BACKGROUND: One of the often-underestimated aspects of obesity is the psychological one. In particular, there is a growing attention to the correlation between obesity and depression among students from all over the world. And also towards the correlation between alcohol abuse and mood disorders. The objective of the study was to examine if the depressive symptomatology, risk of consumption of alcohol and anxiety symptomatology are correlated with obesity/overweight in a sample of students of the University of Palemo, Italy. METHODS: The study was a cross-sectional study. A questionnaire is structured in four sections. An anonymous online survey was sent to a random students sample enrolled in the mailing list of the Regional Authority for the Right to University Study (ERSU) of the University of Palenno, who signed an infomed consent. Results are expressed as adjusted Odds Ratio (aOR) with 95% Confidence Intervals (95% CI). P value <0.05 were statistically significant. RESULTS: Characteristics of the sample: 1102 subjects completed the questionnaire. The mean age of the sample is 22.09 years (SD +/- 3.28). 68.60% of the interviewees are female, 19.06% of the interviewees are overweight or obese. aOR is considered as a dependent variable: "Bodv Mass Index: Overweight-obesity;" the statistically significant independent variables associated are "males" (aOR 2.05). It increases by 8% at each year of age (aOR 1.08), mild (aOR 1.82) and moderate (aOR 2.86) and severe (aOR 2.95) depressive symptomatology. CONCLUSIONS: Male students have a higher probability of being overweight/obese. Overweight/obese people have a higher risk of having severe depressive symptoms. Active interventions of public health planning and implementation of structural and organizational measures would be highly effective for the promotion of correct lifestyles and adequate psychological support.
