to examine the associations of physical activity and television (TV) viewing time with retinal vascular caliber in Australian adults.a total 2024 adults aged 25 yr or older without known diabetes Diabetes, Obesity, Lifestyle Study (AusDiab, 1999-2000), a population-based cross-sectional study, were evaluated. Retinal calibers (both arteriolar venular calibers) measured from digital photographs using computer-assisted method summarized into central artery vein equivalents. Self-reported TV obtained interviewer-administered questionnaires.for activity, no statistically significant multivariate relationships emerged for men women. After adjusting confounders (age, sex, education, cigarette smoking, diet quality, waist circumference, systolic blood pressure, plasma glucose levels, serum fibrinogen, triglyceride, time), who watched at least 2 h·d had that was 4.71 microm (95% confidence interval = 1.37-8.04 microm, P 0.006) wider compared those watching <2 TV. No association noted women.these findings provide first evidence an between (a common, leisure sedentary behavior) microcirculation. Further research is needed these different populations by more comprehensive behavior measures.
