Eating Behavior of Older Adults with and Without Diabetes: The Vigitel Survey, Brazil, 2016

Abstract

Background

A healthy diet is a protection factor against type 2 diabetes and plays an important role in the treatment of the disease, as well as associated comorbidities.

Objective

Characterize the eating habits of older adults (≥ 65 years) with and without diabetes residing in capital cities and the Federal District of Brazil.

Methods

A cross-sectional study was conducted using data from the Surveillance of Risk and Protection Factors for Chronic Diseases Through a Telephone Survey (Vigitel, 2016). The prevalence of diabetes mellitus was estimated according to sociodemographic variables, physical inactivity level, self-rated health status and body mass index. Dietary habits were assessed based on the frequency (weekly and daily) of consumption of healthy and unhealthy foods and the replacement of food by snacks. Differences were determined using Pearson’s chi-square test (Rao-Scott), with the significance level set at 5%.

Results

A total of 13,649 older adults were interviewed. The prevalence of self-reported diabetes was 27.2% (95% CI: 25.5; 29.0). Compared to non-diabetics, diabetic individuals had a higher consumption of raw vegetables (32.1% vs. 26.5%/3-4 days/week) and lower consumption of chicken (3.8% vs. 6.4%/hardly ever/never), fruit juice (24.0% vs. 29.6%) and sweets (6.8% vs. 16.2%) ≥ 5 days/week. Compared to non-diabetics, diabetic individuals consumed more skim milk (51.5% vs. 44.6%) and diet soda (60.0% vs. 17.3%) ≥ 5 days/week, raw vegetables (9.1% vs. 2.5%/at dinner) and sweets (37.7% vs. 20.5%/twice/day) 3-4 days/week.

Conclusion

The observed differences emphasize the need for healthy eating interventions for all older adults, as well as specific counseling for those with diabetes.
