Observation on Obesity Undergoing XOWI

Obesity is a worldwide problem to public health, with a prevalence rate of 12.4% according to recent studies. It is associated with a series of chronic non-communicable diseases, including type 2 diabetes, cardiovascular diseases, non-alcoholic fatty liver, polycystic ovary syndrome, cancer, and so on. Many publications reported Chinese herbal therapy as an effective anti- obesity management. However, there are still few observational studies on its effect in patients undergoing Chinese herbal therapy more than 6 months, or on its safety.

This is a mono-centric, prospective study conducted at Shanghai Municipal Hospital of Traditional Chinese Medicine. Patients with body mass index ≥ 28 Kg/m2 will be consecutively recruited in out-patient clinic of the department of endocrinology or nutrition. Another important including criteria is that each subject is supposed to be chartered by heat-dampness pattern in TCM. Patients will undergo an integrated SRXPY-based obesity wellness intervention(SOWI). They will report weekly diet, daytime physical activities and sleeping time, by means of WeChat and Electrical bracelet. Meanwhile, TCM practitioner and nutritionist will be involved in helping them.

The integrated obesity wellness intervention is based on lifestyle invention and XRXP granule. XRXP granule is composed of several herbs, such as Huang Qin (Baical Skullcap Root), Zi Cao (Root of Sinkiang Arnebia), Hu Zhang (Rhizoma Polygoni cuspidata), Cang Shu (Atractylodis Rhizoma), He Ye (Lotus Leaf), etc. Some components have been found, which can ameliorate serum concentrations of glucagon-like peptide-1 by stimulating gut taste receptors in db/db mice. Also, XRXP granule showed anti-obesity effects (reduction of body weight, body mass index and waist circumstance) in a 12-week pilot study on obese patients.

In this observational study, patients will be investigated every 3 months, until 2 years after enrollment. We will not only test the effect and safety, but test changes of appetite, health- related quality of life, bio markers as well.
