ABSTRACT
Objective. To examine the effect of obesity on incidence of
disability and mortality among non-disabled older Mexicans at
baseline.
Materials and methods. The sample included
8 415 Mexicans aged ≥ 50 years from the Mexican Health
and Aging Study (2001-2012), who reported no limitations in
activities of daily living (ADLs) at baseline and have complete
data on all covariates. Sociodemographics, smoking status,
comorbidities, ADL activities, and body mass index (BMI)
were collected.
Results. The lowest hazard ratio (HR) for
disability was at BMI of 25 to ‹ 30 (HR = 0.97; 95% confidence
interval [CI], 0.85-1.12). The lowest HR for mortality were
seen among participants with BMIs 25 to ‹ 30 (HR = 0.85;
95%CI, 075-0.97), 30 to ‹ 35 (HR = 0.86; 95 %CI, 0.72-1.02),
and ≥ 35 (HR = 0.92; 95 %CI, 0.70-1.22).
Conclusion.
Mexican older adults with a BMI of 25 to ‹ 30 were at less
risk for both disability and mortality.
