[Anxiety disorders. The variability and determinants of the therapeutic approach of primary care physicians]. / Trastornos de ansiedad. Variabilidad y condicionantes de la actitud terapéutica de los médicos de atención primaria.

OBJECTIVES: To analyse the influence of independent factors, relating to the characteristics of primary care doctors, patients and the illness, on therapeutic attitudes and their variability before anxiety disorders. DESIGN: Observational study of people attending primary care family medicine clinics who are identified as suffering anxiety disorders. SETTING: The autonomous Communities of Castilla and Leon, the Basque Country and the Valencian Community. PARTICIPANTS: 3247 patients over 18 classified by their doctors as suffering an anxiety disorder. MEASUREMENTS AND RESULTS: During 1995, 317 primary care doctors collected information from patients with anxiety disorders (CIE codes F40 and F41). The information was gathered with the same questionnaire in the three communities. The data were validated monthly before the final analysis. Women doctors gave less medical advice than male doctors (OR: 0.48, 95% CI: 0.36-0.65). Patients with anxiety in Castilla and Leon were at greater "risk" of receiving drugs treatment than those in the Basque Country (OR: 1.64, CI: 1.31-2.06). When the consultation was for any mental symptom or when the kind of anxiety was a panic disorder (OR: 2.39, CI: 1.53-3.65), phobic disorder (OR: 2.17, CI: 1.52-3.08) or mixed anxiety disorder (OR: 2.20, CI: 1.77-2.73), patients were more likely to be referred for specialist treatment. If it was decided to prescribe drugs treatment, women doctors used more often than their male colleagues a mixed treatment with anti-depressants, anxiolytic drugs and drugs for psychosis (OR: 1.60, CI: 160-4.28). Castilla and Leon, and the Valencian Community were less likely to use mixed treatment than the Basque Country reference group. CONCLUSIONS: This study shows the variability in the difficulties encountered in diagnosis and finding a common standard of conduct for primary care doctors faced with patients suffering anxiety disorders. Although the treatment used for anxiety can be considered adequate in most cases, there is high variability, which depends mainly on the type and other characteristics of the process, the patient and the professional.

[Factors determining infant mortality in Spain]. / Algunos factores determinantes de la mortalidad infantil en España.

We introduce an ecological research for Spain between the 1975 and 1979, trying to explain the variation of childhood mortality. The social-economical factor had an important weight, as the disposable familiar rent (R2 = 0.44) and the per capita rent, while the health factors had a least important influence. From this last group, the health resources utilization were the most important, as the consultation per habitant (partial regression coefficient -0.15 and -0.14 in 1977 and 1978 respectively) and the surgery activities. Every this reflect a country in change.

[Fluoride levels in water for public use in the province of Valencia]. / Niveles de fluor en las aguas de consumo público de la provincia de Valencia.

It has been realized a description study about the fluorine content in the drinking waters from the province of Valencia and it has been looked for the relation with distinct variables in order to prevent possible risks for health. The fluoride level is very low in all the public consumption waters of the province. It has been recommended the fluoridation in order to get prophylaxis of the caries teeth. The structural and geological characteristics of the aquifer don't influence about the fluoride levels in it's water supplies. Fluorine level is lightly industrialized zones and supplies near dumping places of solid and liquid residues situated over vulnerable terrenes to contamination on account of porosity, immediately afterwards fissured zones and finally the mixed terrenes.
