[Preventive effect of social support on mortality among elderly population: a longitudinal study].

BACKGROUND: The main objective of this study is to analyze the relationship between social support and the mortality among a non-institutionalized population cohort age 60 or above residing in Barcelona studied throughout the 1996-1999 monitoring period for the purpose of analyzing the relationship between the social support and the mortality of this cohort. METHODS: In 1996, a telephone survey was conducted of 755 individuals (316 males and 439 females) who had been surveyed in the 1992 Barcelona health survey and who, were age 60 or above that year. The questionnaire included socio-demographic, morbility and health condition, social support and social network-related variables. The deaths during the 1996-1999 period were recorded. Logic regression was used for analyzing the social support-mortality relationship. RESULTS: The deaths for the period in question totaled 55 individuals (5.9% of the females and 9.2% of the males). Among the variables reflecting social support, for the males solely the situation of living with someone was found, in the bivariate analysis, to have a significant relationship to the mortality, which was higher for those males who lived with other family members, but not with their wives or female partner (OR = 3.7; IC 95% 1.4-9.6). Among the females, the existence of support from neighbors, the size of the family network, the number of contacts with the community network and the situation of living with someone else were related to the mortality in the bivariate analysis, although in the multivariate logic regression, solely the support of neighbors (OR = 3.6; IC: 1.1-11.1) was found to have a significant relationship. CONCLUSIONS: The results are consistent with prior studies revealing a relationship between the social support variables and the mortality. The relationship between the different social support variables and the possible prevention mechanisms should be taken up in future studies.

[Passive smoking in bars, restaurants, and discotheques in Florence, Italy].

BACKGROUND: "Environmental Tobacco Smoke (ETS) exposure in a sample of European cities" is the first European multicentre project intended to measure ETS exposure in public places in a number of European cities. OBJECTIVES: To present results of measurements of nicotine concentration in a number of bars, restaurants and discotheques in Florence, Italy. METHODS: The ETS marker was vapour-phase nicotine sampled by passive monitors. At least two monitors were placed in each of seven bars (five in hospitals; one at an airport; one at a railway station), and seven restaurants (three with smoking and non-smoking sections), and left in place for several days. In each of four discotheques two nicotine passive monitors were used as personal samplers. RESULTS: The average nicotine concentration in discotheques, restaurants and bars was respectively 26.78 micro/m3, 2.32 microg/m3 and 0.83 microg/m3. In the smoking section of restaurants with separated areas for smokers and non-smokers the average nicotine concentration was 2.54 microg/m3, which was similar to that measured in non-smoking sections (2.14 microg/m3).

[Environmental tobacco smoke exposure in public places in Florence, Italy].

OBJECTIVES: Measurements of the environmental tobacco smoke (ETS) exposure in public places in Florence. This study was part of the first European multicenter project, intended to measure ETS exposure in public places in a number of European Cities (Florence, Barcelona, Paris, Oporto, Athens, Wien and Orebro). DESIGN: Nicotine vapour phase was measured using passive samplers, composed of a sodium bisulphate treated filter held in a plastic cassette with a windscreen on one side. The filters were analysed at the Laboratory of the Public Health Agency of Barcelona, Spain, by gas-chromatography/mass spectrometry (GC/MS). MAIN OUTCOME MEASURES: Nicotine concentration (in microg/m3) by public place, by smoking policy, and, for restaurants with separated areas, by smoking and non-smoking section. SETTING: Nicotine measurements were conducted in 5 schools, 3 university departments, 5 hospitals, 1 railway station, 1 airport, 7 bars, 7 restaurants, and 4 discotheques in Florence. RESULTS: The average nicotine concentration in discotheques and restaurants were respectively 26.78 microg/m3 and 2.32 microg/m3. In the other public places the concentration was about 1 microg/m3. In smoke-free public places the average concentration was 0.85 microg/m3; in public places where smoking is allowed concentration was higher (11.53 microg/m3). In the smoking section and non-smoking section of restaurants with separated areas the average concentration was respectively 2.54 and 2.14 microg/m3. CONCLUSION: The highest nicotine concentrations were recorded in discos and restaurants. A smoke-free public place is effective in reducing ETS exposure. Smoking and non-smoking sections in restaurants without a separate ventilation system seem not to solve ETS exposure.
