Abstract

ARAUJO, Tânia Aparecida de et al. Health conditions and weight change among the older adults over ten years of the SABE Survey. Epidemiol. Serv. Saúde [online]. 2020, vol.29, n.4, e2020102.  Epub Sep 25, 2020. ISSN 2237-9622.  https://doi.org/10.1590/s1679-49742020000400012.

Objective

To analyze the relationship between health conditions and weight changes among elderly people monitored by the SABE Survey over a ten-year period in São Paulo/SP.

Methods

This was a longitudinal study that followed (2000-baseline, 2006 and 2010) change in body weight (outcome variable) and associated health conditions (exposure variables) in the elderly (n=571); multinomial logistic regression analyses were employed.

Results

Average weight increase in the evaluated period was 29.0%. 34.0% (2006) and 12.5% (2010) lost weight and 18.2% (2006) and 39.9% (2010) gained weight. Prevalence of chronic diseases increased from 34.1% (2000) to 51.9% (2006) and 60.1% (2010). Older people with weight gain also rated their overall health as poorer in 2006 (RR:3.15; 95%CI 1.21;8.17) and 2010 (RR:2.46; 95%CI 1.02;5.94). The higher numbers of diseases (RR:2.12; 95%CI 1.00;4.46) and hospitalizations (RR:3.50; 95%CI 1.40;8.72) were associated with a decrease in weight in 2010.

Conclusion

Weight changes are related to poorer health status among the elderly.
