In 1986 the Cardiology Department, including an outpatient clinic, was established in the community hospital of Savigliano (Italy). In 1987, as a part of a cardiovascular community prevention program, an epidemiological survey on cardiovascular risk factors was carried out. Similar indicators have been object of the study held in 1998 by ANMCO-Istituto Superiore di Sanità: the Italian Cardiovascular Epidemiological Observatory. So, 11 years later, we have had the chance to compare the changes, in the same community, of three important risk factors: tobacco smoking, arterial blood pressure, and obesity.
The 1987 survey included 280 subjects, aged 20 to 59 years. The 1998 survey has examined 200 subjects, aged 35 to 74 years. In both cases the subjects have been randomly selected from the Electoral Registers; subjects were asked to answer a questionnaire on tobacco smoking; arterial blood pressure measured using a cuff manometer was registered and weight and height have been recorded. In order to have comparable data we have only considered subjects 35 to 59 years old.
One hundred and fifty-seven subjects (84 males and 73 females) were included in the 1987 survey and 123 (60 males and 63 females) in the 1998 survey. In 1987, the percentage of smokers was 40.7% (61.4% of males and 17.8% of females), with an average of 23.4 cigarettes/day among males and 14.7 among females. In 1998, the percentage of smokers has dropped to 18.6%, without any differences between sexes, with an average of 11.9 cigarettes/day among males and 12.7 among females. The mean values of blood pressure were lower in 1998 than in 1987 both in males (129.4/85.7 vs 138.0/88.2 mmHg) and females (119.3/80.2 vs 138.4/86.5 mmHg). Although not statistically significant, the percentage of individuals with systolic blood pressure > or = 160 mmHg or diastolic blood pressure > or = 95 mmHg was lower in 1998 (15.9% among males and 14.2% among females) than in 1987 (25.6% among males and 22.8% among females). The mean values of body mass index were unchanged (from 25.4 to 25.2 kg/m2 in males and from 23.4 to 23.1 kg/m2 in females).
The incidence of tobacco smoking and of hypertension has shown a significant reduction in the population of Savigliano between 1987 and 1998. No significant variation was found in body mass index or in the prevalence of obesity. The distribution of these three risk factors seems to be lesser than that reported in northern Italy.
1986年，意大利萨维利亚诺的社区医院设立了心脏病科，包括一个门诊诊所。1987年，作为心血管社区预防项目的一部分，开展了一项关于心血管危险因素的流行病学调查。类似指标是1998年由意大利国家心脏病防治协会 - 国家高等卫生研究院进行的研究（意大利心血管流行病学观察站）的对象。所以，11年后，我们有机会比较同一社区中三个重要危险因素的变化：吸烟、动脉血压和肥胖。
1987年的调查包括280名年龄在20至59岁之间的受试者。1998年的调查检查了200名年龄在35至74岁之间的受试者。在这两种情况下，受试者均从选民登记册中随机选取；受试者被要求回答一份关于吸烟的问卷；使用袖带式血压计测量的动脉血压进行了记录，体重和身高也被记录下来。为了获得可比数据，我们仅考虑35至59岁的受试者。
1987年的调查纳入了157名受试者（84名男性和73名女性），1998年的调查纳入了123名受试者（60名男性和63名女性）。1987年，吸烟者的比例为40.7%（男性为61.4%，女性为17.8%），男性平均每天吸烟23.4支，女性平均每天吸烟14.7支。1998年，吸烟者的比例降至18.6%，男女之间无差异，男性平均每天吸烟11.9支且女性平均每天吸烟12.7支。1998年男性和女性的血压平均值均低于1987年（男性为129.4/85.7 mmHg对138.0/88.2 mmHg，女性为119.3/80.2 mmHg对138.4/86.5 mmHg）。尽管无统计学意义，但收缩压≥160 mmHg或舒张压≥95 mmHg的个体比例在1998年（男性为15.9%，女性为14.2%）低于1987年（男性为25.6%，女性为22.8%）。体重指数的平均值没有变化（男性从25.4降至25.2 kg/m²，女性从23.4降至23.1 kg/m²）。
1987年至1998年间，萨维利亚诺人群中吸烟和高血压的发病率显著降低。体重指数或肥胖患病率未发现显著变化。这三个危险因素的分布似乎低于意大利北部报道的水平。
