Abstract

INTRODUCTION:

The rising number of obese and/or physically inactive individuals might negatively impact human lifespan. This study assessed the association between height, body mass index (BMI) and non-occupational physical activity and the likelihood of reaching 90 years of age, in both sexes separately.

METHODS:

Analyses were conducted using data from the Netherlands Cohort Study. Participants born in 1916-1917 (n=7807) completed a questionnaire in 1986 (at age 68-70 years) and were followed up for vital status information until the age of 90 years (2006-2007). Cox regression analyses were based on 5479 participants with complete data to calculate risk ratios (RRs) of reaching longevity (age 90 years).

RESULTS:

In women, we observed significant associations between reaching longevity and height (RR: 1.05 per 5 cm increment; 95% CI 1.00 to 1.09), BMI at baseline (≥30vs18.5-<25 kg/m2; RR: 0.68; 95% CI 0.54 to 0.86) and BMI change since age 20 years (≥8vs0-<4 kg/m2; RR: 0.81; 95% CI 0.66 to 0.98). In men, height and BMI were not associated with reaching longevity. In women, non-occupational physical activity showed an inverse U-shaped association with reaching longevity, with the highest RR around 60 min of physical activity per day. In men, a positive linear association was observed between physical activity and reaching longevity.

CONCLUSION:

This study indicates that body size and physical activity are related to the likelihood of reaching 90 years of age and that these associations differ by sex.
