Regular, high, and moderate intake of vegetables rich in antioxidants may reduce cataract risk in Central African type 2 diabetics

International Journal of General Medicine, 06/08/2012

Mvitu M et al. – Red beans intake and adequate quantity of intake of vegetables rich in antioxidants were found to be associated with reduced risk of cataract in these Congolese with type 2 diabetes mellitus. Education on nutrition and health promotion programs are needed to encourage people to eat vegetables and fruit.

Methods

  • This was a cross–sectional study, run in Congo among 244 people with type 2 diabetes mellitus.
  • An intake of≥three servings of vegetables rich in antioxidants/day, intake of red beans, consumption of fruit, and cataract extraction were considered as dependent variables.

Results

  • No patient reported a fruit intake.
  • Intake of red beans was reported by 64 patients (26.2%), while 77 patients (31.6%) reported ≥three servings of vegetables rich in antioxidants. High socioeconomic status (OR = 2.3; 95% CI: 1.1–12.5; P = 0.030) and moderate alcohol intake (OR = 4; 95% CI: 1.1–17.4; P = 0.049) were the independent determinants of eating ≥three servings of vegetables rich in antioxidants.
  • Red beans intake (OR = 0.282; 95% CI: 0.115–0.687; P > 0.01) and eating ≥three servings of vegetables rich in antioxidants (OR = 0.256; 95% CI: 0.097–0.671; P = 0.006) were identified as independent and protective factors against the presence of cataracts (9.8% n = 24), whereas type 2 diabetes mellitus duration ≥3 years was the independent risk factor for cataract extraction (OR = 6.3; 95% CI: 2.1–19.2; P > 0.001 in the model with red beans intake and OR = 7.1; 95% CI: 2.3–22.2; P > 0.001 in the model with ≥three servings of vegetables rich in antioxidants).
