| Summary: | Both falls and obesity are major public health issues in older adults and have been
identified as the fifth leading cause of death among older adults. The relationship between
obesity and falls have been conflicting in the limited publications available. This doctoral
research comprised: 1) a cross-sectional study on obesity and falls, 2) a prospective study
on obesity and falls and 3) an intercontinental comparison of relationship between obesity
and falls. The study populations consisted of adults aged ≥55years from the Malaysian
Elders Longitudinal Study (MELoR), the European Prospective Investigation into Cancer
- Norfolk study (EPIC- NORFOLK) and Bavarian Research Foundation-Sarcopenia and
Osteoporosis study (FoRMOSA). Body mass index (BMI), waist circumference (WC),
waist hip ratio (WHR) and percentage body fat (%BF) were associated with falls. Body
composition contributed to 69% of the association between BMI and falls. Prospective
analyses revealed WHR was a stronger risk factor compared to BMI, WC and %BF.
International comparisons found significant associations between BMI and falls in both
Caucasians and Asians. BMI remained as an independent risk factor for falls among
Caucasians but not Asian upon adjusting for body composition. In conclusion, this study
has provided new knowledge on obesity and falls in challenging the value of BMI, with
WHR proposed as a suitable alternative. In the interim, our findings may assist health
professionals and policy makers with the formulation of culturally relevant and targeted
fall prevention interventions to prevent falls among older adults with obesity.
