Background: Studies on the association between obesity and all-cause mortality\nhave found that the degree of obesity is directly proportional to\nall-cause mortality. In contrast, there have been studies indicating that obese\npeople with underlying diseases have a higher survival rate. We hypothesized\nthat age and underlying diseases lead to such contrasting results. Therefore,\nwe conducted a study to clarify the influence of post-middle age obesity and\nunderlying diseases on all-cause mortality. Methods: This study used data\nfrom longitudinal studies in the United States, which conducted follow-up for\n19 years on 33,708 participants in different age groups ........ and .... years. Hazard ratio (HR) was determined using the Cox proportional hazards\nmodel to analyze a group consisting of all participants, a group of those with\nunderlying diseases, and a group of those without underlying diseases, considering\nage, gender, education history, marital status, household income,\nsmoking history, and BMI category as covariates. Results: In the group aged .... without underlying diseases, HR was almost 1 in those with BMI ..... and ..... Further, HR was higher in the 45 - 64 age\ngroup without underlying diseases if BMI was .... However, HR was\napproximately 1 in the .... age group. Conclusions: The study revealed that\namong individuals aged ... years without underlying diseases, there was no\nassociation between obesity and all-cause mortality. Among individuals without\nunderlying diseases, HR was higher in the 45 - 64 age group with BMI .... but was approximately 1 among those aged... years. Therefore, an\ninteraction based on age was detected. These findings may lead to recommendations\nregarding the need to modify the advice and education provided\nto obese individuals in different age groups.
