Effect of Acupoint Catgut Embedding for Abdominally Obese Female with Strong Appetite: Mixed Analysis of a Randomized Clinical Trial

BACKGROUND: Abdominal obesity (AO) is not only a health issue, but also a serious impact on women’s work and life. The article of acupoint catgut embedding (ACE) on AO has already been accepted to be published and showed significant effect. However, whether ACE is effective for abdominally obese female with strong appetite is still unclear. METHODS: This is a mixed analysis of a multicenter, double-blind, randomized controlled trial.Which was conducted in China between July 2018 and March 2020 (n = 101), while with the supplementary samples (n = 22) between April 2020 and June 2022. According to the appetite and intervention methods, 123 abdominally obese female were divided into ACE group with strong appetite (n = 27) and moderate appetite (n = 31), control (non-acupoint catgut embedding) group with strong appetite (n = 37) and moderate appetite (n = 28). Four subgroups were given a 12-week actual intervention period and a 4-week follow-up. Waist circumference (WC), appetite, body weight and BMI were applied and assessed at baseline and after 6, 12 and 16 weeks. RESULTS: In this study, the mean onset age of abdominal obesity in females was 25.27 (8.19) years old. The longer duration of AO, the lower the appetite in females (p<0.05). At 12 and 16 weeks, ACE group with strong appetite showed significant decrease in WC and appetite than control group with strong appetite (p<0.01). However, ACE group with moderate appetite showed no significant decrease than control group with moderate appetite in WC, appetite, body weight and BMI (p>0.05). At 12 and 16 weeks, there was no significant difference in appetite between the ACE groups (strong and moderate appetite)(p>0.05), while there was still a difference between the control groups (p<0.05). CONCLUSION: Younger abdominally obese female had a stronger appetite. ACE own the remarkable therapeutic effects for younger abdominally obese female and showed the perfect effect on appetite-reduction.
