[Physical activity in the regional health plans in Spain: a review of proposals]. / La actividad física en los planes de salud autonómicos de España. Una revisión de propuestas.

OBJECTIVE: To identify if the regional government health plans in Spain include specific objectives and measures related to physical activity. METHOD: Institutional websites were scanned to identify the most recent health plan of each regional government. The information included in the health plans on objectives and measures and the population groups targeted by these measures was extracted. The search was completed on 24 January 2022. RESULTS: Sixteen health plans were identified of which six are in force in 2022; 15 of these have incorporated specific objectives and measures on physical activity. Most of the actions are focus on general population, children-adolescents and elderly population. The plans of Cantabria, the Comunitat Valenciana and País Vasco cover physical activity more widely, proposing measures for seven of the eight identified population groups. CONCLUSIONS: Most of the health plans include measures related to physical activity and target two or more population groups. The objectives, specific measures and population groups were highly heterogeneous. This study could serve to prompt regional governments to review their health plans, update them and improve them in terms of physical activity. It seems advisable that the different health plans should have a homogeneous framework of proposals related to the promotion of physical activity.

Serum cotinine cut-points for secondhand smoke exposure assessment in children under 5 years: A systemic review.

BACKGROUND: Serum cotinine has become the most widely used biomarker of secondhand smoke exposure (SHS) over time in all ages. The aim of this study was to review the serum cotinine cut-points used to classify children under 5 years as exposed to SHS. METHODS: A systematic review performed in the Pubmed (MEDLINE) and EMBASE databases up to April 2021 was conducted using as key words "serum cotinine", "tobacco smoke pollution" (MeSH), "secondhand smoke", "environmental tobacco smoke" and "tobacco smoke exposure". Papers which assessed SHS exposure among children younger than 5 years old were included. The PRISMA 2020 guidelines were followed. Analysis was pre-registered in PROSPERO (registration number: CRD42021251263). RESULTS: 247 articles were identified and 51 fulfilled inclusion criteria. The selected studies were published between 1985-2020. Most of them included adolescents and adults. Only three assessed postnatal exposure exclusively among children under 5 years. None of the selected studies proposed age-specific cut-points for children < 5 years old. Cut-point values to assess SHS exposure ranged from 0.015 to 100 ng/ml. The most commonly used cut-point was 0.05 ng/ml, derived from the assay limit of detection used by the National Health and Nutrition Examination Survey (NHANES). CONCLUSIONS: No studies have calculated serum cotinine age-specific cut-points to ascertained SHS exposure among children under 5 years old. Children's age-specific cut-points are warranted for health research and public health purposes aimed at accurately estimating the prevalence of SHS exposure and attributable burden of disease to such exposure, and at reinforcing 100% smoke-free policies worldwide, both in homes, private vehicles and public places.
