Obesity parameters may predict incident rosacea risk in women
Parameters of obesity, including BMI and waist circumference, were associated with significant increases in rosacea risk, according to recent findings.
The study included 89,886 women from the Nurses’ Health Study II, which ran from 1991 to 2005. The researchers collected data on rosacea diagnoses in 2005 and followed the cohort for 14 years.
Results showed 5,249 cases of incident rosacea overall.
Increased BMI was associated with an increased rosacea risk (P < .0001). More specifically, individuals with a BMI of 35 kg/m2 or higher had a significantly higher risk for rosacea than those with a BMI of 21 to 22.9 kg/m2 (HR = 1.48; 95% CI, 1.33-1.64).
Weight gain after age 18 years also increased the risk for rosacea (P < .0001), with each 10-pounds weight gain trending the risk upward (HR = 1.04; 95% CI, 1.03-1.05).
Higher waist and hip circumference were other parameters that significantly increased rosacea risk (P < .0001). The researchers suggested that these associations were likely independent of BMI.
“Measures of obesity were significantly associated with an increased risk for incident rosacea,” the researchers concluded. – by Rob Volansky
