Introduction:

The aging process is characterized by several changes in individuals’ life, including his or her nutritional status and food intake. To understand the trends of these changes, studies with elderly people who were born at different times are necessary.

Objective:

To compare the nutritional status and food intake of elderly people who participated in the Health, Well-being, and Aging study (SABE study), conducted in São Paulo, in 2000 and 2010.

Methods:

The nutritional status was identified by means of the body mass index (BMI) and was classified as underweight (BMI < 23 kg/m²), adequate weight (23 ≤ BMI < 28 kg/m²), or overweight (BMI ≥ 28 kg/m). Food intake was self-reported and was classified as the number of meals (≥ 3/day), frequency of intake of dairy products (≥ 1 serving/day), eggs and beans (≥ 1 serving/week), fruits and vegetables (≥ 2 servings/day), meat (≥ 3 servings/week), and liquids (≥ 5 glasses/day). The prevalence ratio was calculated to compare the variables of the cohorts, using Poisson regression.

Results:

A total of 755 individuals of both the genders aged 60 to 64 years and who were born between 1936 and 1940 and between 1946 and 1950 participated in this study. Elderly people who were born between 1946 and 1950 presented higher prevalence ratio of overweight (PR = 1.19), number of meals (PR = 1.34), and liquids intake (PR = 1.18), but presented lower prevalence of intake of dairy products (PR = 0.87), meats (PR = 0.93), and fruits and vegetables (PR = 0.83).

Conclusion:

These results showed concerning scenarios of nutritional status and food intake for the most recent cohort (1946 - 1950).
