Predictors for Smoking Cessation with Acupuncture in a Hong Kong Population

Abstract EN

Background.

Observational studies of smoking cessation with acupuncture have been reported widely; however, few researchers have focused on its predictors.

Objective.

This paper attempts to explore the predictors for smoking cessation with acupuncture in a Hong Kong population, aiming to provide references for clinical treatment in the future.

Methods.

We performed a secondary analysis of data from our observational study “Acupuncture for Smoking Cessation (2011–2014)” in Hong Kong.

A total of 23 indexes were selected as possible predictors, and study participants with complete information of 23 indexes were included.

By taking 8-week and 52-week smoking cessation results as dependent variables, binary logistic regression method was used to identify the predictors.

Additionally, based on an M5P decision-tree algorithm, an equation of “successful rate of smoking cessation with acupuncture” was calculated.

Results.

(1) 2,051 study participants were included in total.

(2) According to the results of binary logistic regression, variables including treatment location, total number of acupuncture sessions received, and whether the study participants received at least 6 sessions of acupuncture were taken as the short-term predictors; gender, treatment location, Fagerstrom Test for Nicotine Dependence (FTND), and total number of acupuncture sessions received were taken as the long-term predictors.

(3) According to study participants’ FTND, treatment location, and number of cigarettes smoked/day, the equation of “successful rate of smoking cessation with acupuncture” was established.

Conclusion.

Receiving sufficient and qualified acupuncture is the leading factor for short-term smoking cessation with acupuncture, whereas individual factors and smoking background play a more important role in long-term smoking cessation with acupuncture.
