How Has the COVID-19 Pandemic Changed BMI Status and Physical Activity - Its Associations with Mental Health Conditions, Suicidality: An Exploratory Study

Background: The COVID-19 pandemic has psycho-socially impacted people of all age groups. The consequences related to this crisis may increase the suicide mortality rate as reported in prior pandemics. Although many studies have been conducted identifying suicidal behavior attributing factors, there is a lack of knowledge on the associations of body mass index (BMI) and physical activities, their changes, and suicidal behavior, which were explored herein for the first time.

Methods: An online-based, cross-sectional study was carried out with a total of 324 Bangladeshi people (mean age = 26.99 ± 8.17 years). The measures included questions on socio-demographics, health-related variables, physical activities-related variables, and mental health problems (eg, depression, anxiety and suicidal behavior).

Results: About 41.0% and 29.3% of the participants reported being depressed and anxious, respectively, whereas suicidal behavior after the pandemic's inception was found to be 6.5%. Although the role of BMI status either prior to or during the pandemic in mental health conditions was not statistically significant, the changes of BMI status were (that is, those with decreasing BMI status compared to no change in BMI status were at greater risk of depression and anxiety, which was followed by increasing BMI status). Besides having no outside space for exercise and performing more physical activities prior to the pandemic were reported to increase anxiety levels, but no significant associations between changes in physical exercise frequency and other mental health problems were observed.

Conclusion: In summary, the present findings showed that people with either decreased or increased BMI status after the inception of the pandemic were at greater risk of mental instabilities, which is a concern which should be considered when adopting any preventive approaches.
