Assessment study of the nutritional status, eating habits and physical activity of the schooled population of Centelles, Hostalets de Balenyà and Sant Martí de Centelles (ALIN 2014 Study).

Background And Objective: Malnourishment can be caused by either a lack of food or an excess of low-nutrient foods. Due to several factors, this predisposes children to academic failure. The objective of this study is to estimate the prevalence of school children with eating problems, study their nutrition level, food quality in the diet, and level of physical activity.

Primary vaccination of adults with reduced antigen-content diphtheria-tetanus-acellular pertussis or dTpa-inactivated poliovirus vaccines compared to diphtheria-tetanus-toxoid vaccines.

Objective: To evaluate immunogenicity and reactogenicity of primary vaccination with reduced-antigen-content diphtheria-tetanus-acellular pertussis (dTpa) or dTpa-inactivated poliovirus (dTpa-IPV) vaccine compared to diphtheria-tetanus-toxoid vaccines (Td) in adults > or = 40 years of age without diphtheria or tetanus vaccination for 20 years or with an unknown vaccination history.

Research Design And Methods: Double-blind, randomized, controlled clinical trial. Primary vaccination with either three doses of dTpa, one dose of dTpa-IPV followed by two doses of Td, or three doses of Td vaccine (control) administered in a 0-1-6-month schedule.
