ABSTRACT
PURPOSE:
The objective of the present study was to investigate whether dietary patterns are associated with excess weight and abdominal obesity among young adults (23-25 years).METHODS:
A cross-sectional study was conducted on 2061 participants of a birth cohort from Ribeirão Preto, Brazil, started in 1978-1979. Twenty-seven subjects with caloric intake outside ±3 standard deviation range were excluded, leaving 2034 individuals. Excess weight was defined as body mass index (BMI ≥ 25 kg/m(2)), abdominal obesity as waist circumference (WC > 80 cm for women; >90 cm for men) and waist/hip ratio (WHR > 0.85 for women; >0.90 for men). Poisson regression with robust variance adjustment was used to estimate the prevalence ratio (PR) adjusted for socio-demographic and lifestyle variables. Four dietary patterns were identified by principal componentanalysis:
healthy, traditional Brazilian, bar and energy dense.RESULTS:
In the adjusted analysis, the bar pattern was associated with a higher prevalence of excess weight (PR 1.46; 95 % CI 1.23-1.73) and abdominal obesity based on WHR (PR 2.19; 95 % CI 1.59-3.01). The energy-dense pattern was associated with a lower prevalence of excess weight (PR 0.73; 95 % CI 0.61-0.88). Men with greater adherence to the traditional Brazilian pattern showed a lower prevalence of excess weight (PR 0.65; 95 % CI 0.51-0.82), but no association was found for women. There was no association between the healthy pattern and excess weight/abdominal obesity.CONCLUSIONS:
In this sample, the bar pattern was associated with higher prevalences of excess weight and abdominal obesity, while the energy-dense (for both genders) and traditional Brazilian (only for men) patterns were associated with lower prevalences of excess weight.Key words
