This study was attempted to assess if elevated body weight or central obesity is correlated with a higher risk of developing dementia in a representative sample of older English adults. Researchers included a total of 6,582 individuals from the English Longitudinal Study of Ageing who were aged ≥50 years and were dementia-free at baseline, that being either wave 1 (2002–2003) for study members who started at wave 1 or at either wave 2 (2004–2005) or 4 (2008–2009) for those who began the study as refreshment samples. The association between baseline BMI levels or abdominal obesity in relation to dementia incidence was evaluated during the mean follow-up period of 11 years using Cox proportional hazards models. This study's findings reveal that having an elevated body weight or abdominal obesity are correlated with increased dementia incidence. Moreover, these data have significant implications for dementia prevention and overall public health.
