Abstract
High body mass index (BMI) has been established as a risk factor of cardiovascular disease (CVD), but there is still uncertainty about the degree of risk in relation to BMI categories, continuous BMI and pattern of change. These associations must be elucidated by a thorough synthesis of current prospective evidence. A meta-analysis and systematic review were performed in accordance with the PRISMA 2020 guidelines. Every major database was investigated to find possible cohort studies that may analyse the relationship between BMI and cardiovascular outcomes in adults. Similar BMI-CVD associations were carried out by random-effects meta-analyses when pooling of the studies was not possible, and descriptive synthesis was applied. The I2 statistic was used to test heterogeneity, and the funnel plot was used to test publication bias. Ten potential cohort studies with various populations were incorporated. Obesity was linked to a much higher risk of cardiovascular disease compared to normal BMI; overweight status was linked to a smaller and more heterogeneous association. The sustained BMI measurements showed that there was a positive linear correlation existing between rising BMI and the occurrence of myocardial infarction, stroke, coronary heart disease, and CVD mortality. Longitudinal studies showed that the significant BMI gain with time was linked to significantly high cardiovascular mortality, and significant unintentional BMI losses were correlated with increased risk. Subgroup and sensitivity analyses proved the validity of results in terms of sex, age, geographical area, and quality of the study. Funnel plot analysis indicated the potential small-study effects but could not be interpreted due to heterogeneity. High BMI is uniformly correlated with high risks of cardiovascular disease and obesity carries a significantly higher risk than overweight. Growth in BMI and negative BMI trends only worsen cardiovascular risk. These results highlight the significance of the prevention of obesity in early years of life, management of weight throughout life, and extensive evaluation of cardiovascular risks.
