Background: The global development and distribution of vaccinations against the COVID-19 pandemic has been accelerated. If we want our vaccines to work as well as possible, we need to know what makes the immune response to them tick. One such factor that determines immunological response is body mass index (BMI), which is a measure of how much fat a person has. Heartfulness meditation, a practice that promotes emotional well-being, has also shown promise in enhancing immune function. This study aims to explore the correlation between BMI and antibody titers post COVID-19 vaccination and investigate the potential impact of Heartfulness meditation on this relationship.
Methods: A cross-sectional study was conducted on a sample of individuals who received the COVID-19 vaccine. BMI was calculated based on height and weight measurements. Antibody titers were assessed using standardized laboratory tests. Participants were categorized into BMI groups (normal weight, overweight, and obese) for analysis. Heartfulness meditation practice was assessed through self-report measures.
Results: The study included 72 participants who had received the COVID-19 vaccine. Analysis revealed a no significant correlation between BMI and antibody titers post vaccination. The study participants fell into the category of “normal” and “underweight”. In the underweight group, neutralising antibodies were detected at 0 months (97.2098 ±4.65125), 3 months (97.8168 ±2.55290), and 6 months (98.5063 ±.80221), while in the normal body weight group, they were detected at 0 months (95.5272 ±11.40342, at 3 months (-95.4111 ±10.26813), and at 6 months (96.3005 ± 7.76224). This shows no difference in antibody titre between the different body weight.
Conclusion: This study demonstrates no association between BMI and antibody titers post COVID-19 vaccination, suggesting that obesity may adversely affect the immune response. Future research should explore the underlying mechanisms and conduct longitudinal studies to evaluate the sustainability of these effects. Implementing meditation interventions alongside vaccination efforts may help optimize immune response, particularly in individuals with higher BMIs
