THAO-CHILD HEALTH PROGRAMME: COMMUNITY BASED INTERVENTION FOR HEALTHY LIFESTYLES PROMOTION TO CHILDREN AND FAMILIES: RESULTS OF A COHORT STUDY.

INTRODUCTION: childhood obesity is one of the main public health concerns. The multifactorial and multilevel causes require complex interventions such the community based interventions (CBI). Thao-Child Health Programme is a CBI implemented in Spain since 2007. GOAL: show the Thao methodology and the latest cross-sectional and longitudinal results. METHODS: longitudinal cohort study (4 years of follow- up) and cross sectional study. RESULTS: the longitudinal study found an increase of 1% in the overweight prevalence after a follow-up of 4 years of Thao-Programme implementation in 10 municipalities with 6 697 children involved. The cross-sectional study carried out with 20 636 children from 22 municipalities found a childhood overweight prevalence of 26.6%. DISCUSSION: currently a brake in the increase of childhood overweight prevalence is considered a success due to the high prevalence worldwide. More studies well methodologically performed are needed to know the efficacy of the CBI's in this field.

Introducción: la obesidad infantil es una de las principales preocupaciones de salud pública. La etiología multifactorial y multinivel requiere de intervenciones complejas como las intervenciones de base comunitaria (CBI). El Programa Thao-Salud Infantil es una CBI implementada en España desde 2007. Objetivo: mostrar la metodología Thao y los últimos resultados transversales y longitudinales. Métodos: estudio de cohortes longitudinal (4 años de seguimiento) y estudio transversal. Resultados: el estudio longitudinal encontró un incremento del 1% en la prevalencia de exceso de peso tras 4 años de implementación del Programa Thao en 10 municipios con 6.697 niños y niñas involucrados. El estudio transversal llevado a cabo con 20.636 niños y niñas de 22 municipios encontró una prevalencia de exceso de peso infantil del 26,6%. Discusión: actualmente un freno en el incremento de la prevalencia de exceso de peso infantil es considerado como un éxito debido a la alta prevalencia a nivel mundial. Son necesarios más estudios metodológicamente bien realizados para conocer la eficacia de las CBI en este campo.

Relationship between lactate dehydrogenase activity in saliva and oral health status.

OBJECTIVE: Lactate dehydrogenase (LDH) activity in serum increases as a marker of cellular necrosis. LDH activity in saliva could constitute a specific indicator of oral mucosal lesions with tissue breakdown including periodontal disease. The aim of this study was to determine LDH activity in saliva, assessing inter-individual variations with regard to the oral health status. MATERIALS AND METHODS: An oral and perioral examination was performed on a study group of 175 volunteers, to assess the number of missing teeth, caries, fillings, dental prosthesis, periodontal status and temporomandibular joint condition. LDH activity was determined from stimulated whole saliva. RESULTS: After adjustment by age, gender, smoking habits, missing teeth and use of removable prosthesis, the multivariate analysis showed that increased LDH activity was associated with periodontal disease, specifically with the presence of calculus and pockets greater than 5mm. CONCLUSION: LDH activity in whole saliva could be useful as a biochemical marker of periodontal status.
