Why the study?
While obesity indices such as BMI have been linked to diabetic retinopathy, the association with weight-adjusted-waist index (WWI) remains unclear and not fully elucidated.
Are higher weight-adjusted-waist index and body mass index associated with an increased prevalence of diabetic retinopathy in American adults aged 40 and above?
Are higher weight-adjusted-waist index and body mass index associated with an increased prevalence of diabetic retinopathy in American adults aged 40 and above?
Answers are grounded in this paper and cite their sources.
Both weight-adjusted-waist index and body mass index are independently associated with diabetic retinopathy risk among older US adults, highlighting the importance of central obesity measures in assessing diabetic complications.
Diabetic retinopathy (DR) is a common complication of diabetes, with its prevalence increasing globally. While previous research has linked obesity indices such as body mass index (BMI) to DR, the association with weight-adjusted-waist index (WWI) remains unclear. Additionally, the relationship between WWI and DR has not been fully elucidated. This cross-sectional study analyzed data from the National Health and Nutrition Examination Survey (2005-2008) to investigate these associations in Americans aged 40 and above. The study included 5436 participants (2705 men and 2731 women). Weighted logistic regression analysis revealed a significant increase in DR prevalence with higher WWI and BMI values. Smooth curve analysis demonstrated a linear correlation between WWI and DR. The findings suggest that both WWI and BMI are independently associated with DR risk among older US adults, highlighting the importance of considering central obesity measures in assessing diabetic complications.
