[Acupuncture for treatment of tobacco withdrawal syndrome: systematic review and Meta-analysis].

OBJECTIVE

To systematically review the efficacy of acupuncture for the treatment of tobacco withdrawal syndrome.

METHODS

The randomized controlled trials (RCTs) regarding acupuncture for treatment of tobacco withdrawal syndrome were searched in CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane, Medline and EMbase databases. The search period was from January 1st of 2011 to December 31st of 2021. After data extraction and bias risk assessment of the included literature, the Meta-analysis was performed using RevMan5.4.1 software.

RESULTS

Totally 23 RCTs were included, including 2 120 patients. The Meta-analysis results showed that compared with medication, acupuncture showed no significant difference at improving Fagerström test for nicotine dependence (FTND) score (=0.16, 95%: -0.08, 0.41), heaviness of smoking index (HSI) score (=0.11, 95%: -0.13, 0.36), Minnesota nicotine withdrawal scale (MNWS) score (=0.12, 95%: -0.11, 1.35), questionnaire of smoking urges (QSU) score (=-0.30, 95%: -2.78, 2.18), Hamilton depression scale (HAMD) score (=0.76, 95%: -1.54, 3.06), abstinence rate (=0.95, 95% : 0.82, 1.10) and effective rate (=1.01, 95%: 0.95, 1.07). Acupuncture was superior to sham acupuncture in reducing MNWS score (=-4.88, 95%: -5.21, -4.55, <0.000 01). Acupuncture was superior to cognitive behavioral therapy in reducing FTND score (=-1.41, 95%: -1.74, -1.08), MNWS score (=-4.28, 95%: -5.31, -3.25) and increasing abstinence rate (=2.19, 95%: 1.39, 3.45, <0.000 01, <0.001).

CONCLUSION

Acupuncture could effectively improve tobacco withdrawal syndrome, increase abstinence rate and effective rate. Limited by the quantity and quality of the included studies, this conclusion needs to be verified by more studies.
