The effect of MPOWER scores on cigarette smoking prevalence and consumption.

BACKGROUND: The World Health Organization (WHO) introduced the MPOWER package to support policy implementation under the Framework Convention on Tobacco Control (FCTC). This study examined the effect of MPOWER policies on smoking prevalence and cigarette consumption in a global context. METHODS: The MPOWER composite score was constructed by adding up the six MPOWER scores for each country and survey year 2007-2008, 2010, 2012, and 2014, with a possible range between 6 (1 in each of the six score) and 29 (4 in M score and 5 in POWER scores). MPOWER composite scores that measured policy implementation were then linked to cigarette smoking prevalence and consumption data from Euromonitor International. Fractional logit and OLS regressions were employed to examine the effect of the composite MPOWER score on adult smoking prevalence and cigarette consumption, respectively. RESULTS: Results indicate that a 1-unit increase in the composite score reduces smoking prevalence by 0.2 percentage points (p<0.05) among adults and 0.3 percentage points (p<0.01) among adult males; and a reduction of 23 sticks of cigarette (1 pack of cigarettes) in cigarette consumption per capita per year. At this rate, if countries had implemented the MPOWER package to the highest levels during 2007-2014, they would have experienced a reduction in smoking prevalence of 7.26% among adults and 7.87% among adult males and a reduction of 13.80% in cigarette consumption. CONCLUSIONS: MPOWER policies were effective in reducing cigarette smoking among adults. Parties should continue to implement MPOWER policies that have been recommended by the WHO FCTC to curb tobacco epidemic.
