[Public health structures in Spain: a changing panorama].

In the last years the health care system in Spain has undergone very important transformations. However, the public health services have not followed a comparable process. Until 1979 public health structures were based in central services and their provincial units, on one side, and in the resources of local governments on the other. From then on began the process of transferring responsibilities and resources to the regional governments of Autonomous Communities (AC), which today manage most public health services, while the central government keeps as its responsibility the development of basic norms, the administration of public health services at borders and customs, and the general health coordination. The situation in 1995 resembles that of a Federal Country, although the Kingdom of Spain is not formally defined as such. The role of central government services is visibly reoriented towards coordination and the building of consensual and shared structures for health information, for need evaluation, and for policy formulation and evaluation. Although the General Health Law of 1986 considered public health as a main axis for all health agencies, its actual development has been more patchy. Several AC with an Autonomous Health Service have kept public health services separated from it. Besides, many public health functions and activities are developed today from other structures. The processes of change reveal two contradictory aspects. On one side, structures have been upgraded after decentralization, and teams reinforced, with trained and full-time staff. However, there is some dilution of public health responsibility in the periphery, and a lower visibility of the health authority.

[Determinants of quitting smoking in Catalonia, Spain].

OBJECTIVE: While trends in the prevalence of smoking and ex-smoking in Catalonia, Spain have been monitored, the characteristics of those smokers who quit have not been investigated. The aim of this investigation was to analyze the prevalence of cessation, or quit ratio, in Catalonia and to study its sociodemographic, life-style, and smoking correlates. SUBJECTS AND METHODS: We analyzed data collected in the Catalan Health Interview Survey conducted in 1994. This is a cross-sectional study based on a representative sample of the non-institutionalized population of Catalonia. We included for analysis a total of 5,424 subjects (3,649 males and 1,775 females) who declared to be current smokers (2,335 males and 1,331 females) or past smokers (1,314 males and 444 females). We computed the crude and age-standardized quit ratios (QR) or prevalence of cessation, as well as the odds ratio (OR) of quitting smoking, according to gender and the variables studied. RESULTS: The age-standardized QR was 31. 8% for males and 30.9% for females and increased with age. The QR was, both in males and females, greater among married subjects, with higher socioeconomic status, and with healthy life-styles (moderate and heavy leisure physical activity and moderate alcohol consumption). The OR of quitting smoking was higher in heavy smokers (OR = 2.9; 95% CI: 2.2-3.8; smokers of > 30 cigarettes/day vs. 1-10 cigarettes/day) in males, while it was < 1 for females of medium intensity, conforming a shaped curve rather than a linear trend (OR = 1.7; 95% CI: 1.0-2.9, in heavy smokers). CONCLUSIONS: This study confirms a positive association in males and females between quitting smoking and increasing age, a higher socioeconomic level, heavy smoking, and healthy life-styles. The identification of these groups should facilitate the planning of successful interventions. Further effort is also necessary to target groups with low cessation rates, such as individuals in disadvantaged social classes and light smokers.

Cisapride treatment changes the evolution of infant asthma with gastroesophageal reflux.

Gastroesophageal reflux has been named as a possible etiologic factor in infant asthma. We studied 28 boys and six girls aged 19.4 +/- 4.8 months whose asthma began at the age of 7.5 months (1 to 28 months). A common protocol including allergy tests and 24-h intraesophageal pH monitoring (IEpHM) was used. Patients with pathologic 24-h IEpHM were treated with cisapride while the rest were considered the control group. Symptoms score and drug consumption were evaluated in both groups, and 24-h IEpHM was repeated at 4 months. IEPHM was pathologic in 65.6% of the infants. In the cisapride group, wheezing crisis frequency decreased from 4.9 +/- 2 to 0.75 +/- 1.2 (p < 0.0002), and only 10% of patients needed basic pharmacologic treatment. The second IEpHM was normal in eight cases, pathologic in six and was not performed in seven. In the controls, wheezing crisis frequency decreased from 4.6 +/- 2.4 to 0.75 +/- 1.8 (p < 0.01), but 44% needed basic pharmacologic treatment (p < 0.05). In conclusion, gastroesophageal reflux is a frequent but not universal finding in infants with asthma; and cisapride treatment spectacularly reduces wheezing crisis frequency and antiasthmatic drug consumption in these patients.
