According to the findings of a new study published recently by Journal of the American Academy of Dermatology, increase in BMI (Body mass index), increased waist to hip circumference, and massive weight gain from the age of eighteen and above, increases the risk of Rosacea in women.
These findings were recorded from the results of an on-going medical research pioneered by Dr. Wen-Qing Li of Brown University, who is assistant professor of dermatology in the institution. This conclusion was made based on the data obtained from 89,886 nurses who are subjects in an on-going questionnaire raised every two years, which studies the lifestyle, medical history and health status of 116,000 American Nurses, started in 1989. This study is called Nurses’ Health Study II. Data collected and analyzed includes the changes in the weights of the nurses after 18 years of age, their body mass index (a comparison of their height to their weight), their waist to hip circumference, and other parameters that measure central obesity.
Considering the standard of the CDC (Centre for Disease Control), which states that body mass index of 30 is the peak point for obesity to occur, the study discovered that the nurses who have BMI of more than 35 stand a greater risk of developing Rosacea than those nurses with BMI of 21 to 24.9.
The study also recorded that after the age of 18, every 10 pounds increase in weight accounts for four percent increased risk of Rosacea. They also found that increase in waist to hip circumference also increases the risk of Rosacea.
The researchers tried to discover the mechanism through which obesity relates with Rosacea, and they found that there are several mechanisms through which this relationship can be established. Due to the status of chronic low-grade inflammatory, obesity has the tendency of hindering the expression of some immune cells that could inhibit the development of Rosacea. Another possible factor could be due to the vascular changes that occur in obesity, which could lead to vasodilation of Rosacea.
The research leader, Dr. Li, in a statement, recounted that since obesity causes lots of adverse health conditions including psoriasis, atopic dermatitis, acne and other skin conditions, it could also be associated with Rosacea.
Dr. Li and his group received a grant of $25,00 from the Society of National Rosacea, to fund this program, which is geared at increasing awareness on the causes and important factors about Rosacea, including the way to manage it, and possible preventive and curative measures. Currently, the group is conducting another research to establish a link between hormonal changes in pregnancy and menopause, and the development of Rosacea in women.
