[Deaths from noncommunicable diseases attributable to behavioral risk factors in Italy and Italian regions, 2016]. / Decessi per patologie non trasmissibili attribuibili a stili di vita in Italia e nelle regioni italiane nel 2016.

ABSTRACT

OBJECTIVES: to estimate the number of deaths from noncommunicable chronic diseases (NCD) attributable to behavioural risk factors (tobacco smoking, unhealthy nutrition, physical inactivity, overweight, and excessive alcohol use) in 2016 for Italy and for the Italian regions. DESIGN: descriptive study. SETTING AND PARTICIPANTS: mortality data were obtained by the Italian National Institute of Statistics. Causes of deaths from NCD associated with the five RFs were selected. Italian attributable fractions were obtained by the 2016 estimates of the Global Burden of Disease Study and applied to the mortality data. Regional prevalence of risk factors was obtained by the national surveillance system PASSI for the years 2013-2016. MAIN OUTCOME MEASURES: absolute number of attributable deaths, joint attributable fraction, proportion of total deaths attributable to RFs (MAprop). RESULTS: about 191,000 out of 614,307 deaths occurred in Italy in 2016 were attributable to combined RFs (about 37% in males; 26% in women). Joint MAprop was between 33% in men (24% in women) from Val d'Aosta and 40% in men (31% in women) from Campania. In Italy, 17% and 6% of the total amount of deaths were attributable to smoking in men and women, respectively; 6% and 3% to alcohol abuse; 7% and 8% to overweight; 13% and 12% to dietary RFs, and 2% and 3% to low physical activity. The higher proportion of attributable deaths by age-group was recorded in people aged 40-59 years (43% in men; 28% in women). Regional differences in attributable deaths are confirmed by regional RF prevalence recorded by the PASSI surveillance system for the years 2013-2016. CONCLUSIONS: these are the first estimates of the number of deaths due to NCDs attributable to behavioural RFs estimated for each region and for Italy as a whole. Effective primary prevention policies should be reinforced, since these RFs are potentially modifiable.
