Orthodontic treatment need in Spanish schoolchildren: an epidemiological study using the Index of Orthodontic Treatment Need
2008
SUMMARY The aim of this study was to determine the prevalence of malocclusion and orthodontic treatment need in 12- to 16-year-old Spanish schoolchildren using the aesthetic component (AC) and Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and to analyse the relationship with gender and age. The study followed the World Health Organization recommendations for oral health surveys. The sample comprised 655 schoolchildren (306 males and 349 females) who had not undergone orthodontic treatment, divided into two groups: 363 12-year-olds and 292 15- to 16-yearolds, out of a representative sample of the school population of the Valencian Community. The IOTN results…
Comorbidity between depressive symptoms and migraine: preliminary data from the Zabút Aging Project
2008
We evaluated the association between depressive symptoms and migraine using cross-sectional data from the Zabút Aging Project, a population-based study including subjects agedor =50 years. A total of 1285 nonmigraineurs and 151 migraineurs were included. Diagnosis of migraine was carried out using the criteria of the International Headache Society. The Center for Epidemiologic Studies Depression scale (CES-D) was used to score depressive symptoms. Depressive symptoms were clustered in four groups: depressed and positive affects, somatic activity and intrapersonal feelings. Migraineurs showed higher total and specific depressive symptoms than controls (p from 0.005 to0.0001). Mild-to-moderat…
Prevalence of pressure ulcers in the paediatric population and in primary health care: An epidemiological study conducted in Spain.
2018
Abstract Aim The primary goal of this study was to estimate the prevalence of pressure ulcers in the paediatric population cared for in primary health care. Materials The data of this epidemiological study were extracted from the records of the 24 departments that attended to an approximate population of 1 million inhabitants between 0 and 18 years old from 2012 to 2015. The study included children requiring assistance to reduce pressure ulcer incidence. The paediatric population was categorised into neonates and infants (0–2 years), young child (3–6 years), child (7–12 years) and adolescents (13–18 years). The primary outcome was information on the prevalence of pressure ulcers. Secondary …
Evidence-based development of school-based and family-involved prevention of overweight across Europe: The ENERGY-project's design and conceptual fra…
2010
Background There is an urgent need for more carefully developed public health measures in order to curb the obesity epidemic among youth. The overall aim of the "EuropeaN Energy balance Research to prevent excessive weight Gain among Youth" (ENERGY)-project is the development and formative evaluation of a theory-informed and evidence-based multi-component school-based and family-involved intervention program ready to be implemented and evaluated for effectiveness across Europe. This program aims at promoting the adoption or continuation of health behaviors that contribute to a healthy energy balance among school-aged children. Earlier studies have indicated that school and family environmen…
Immunoglobulin M seropositivity for Toscana virus in a random population sample in Sicily.
2012
Summary Objectives High Toscana virus (TOSV) antibody seropositivity rates have been documented in the last decade, especially in the Mediterranean area. It is unclear if these rates are associated with a recent or past exposure to the virus. This is of importance, as primary infection can cause neurologic complications, especially in adults. The aim of the present study was to assess the current active TOSV circulation in western Sicily. Methods A cross-sectional seroprevalence study was conducted on 271 individuals aged 4–92 years, sampled from the general population of a small city. Each participant completed a self-administered questionnaire and provided serum, which was analyzed for th…
Seroprevalence of and risk factors for Toscana and Sicilian virus infection in a sample population of Sicily (Italy).
2011
Summary Objective The present study aimed to assess seroprevalence of and risk factors for Toscana (TOSV) and Sicilian (SFSV) virus infections in a sample of Sicilian subjects. Methods A cross-sectional seroepidemiological study was conducted on 271 individuals. Each participant completed a self-administrated questionnaire and provided a serum sample which was analyzed for the presence of IgG specific anti-TOSV and anti-SFSV viruses. Results Overall, 90 subjects (33.2%) were positive for TOSV IgG, 25 (9.2%) were positive for SFSV IgG and 11 (4%) were positive for both the viruses. A higher risk for TOSV seropositivity was found in participants who were older (adjOR = 1.02 per year; 95% CI =…
PREVALENCE OF PERTUSSIS IgG ANTIBODIES IN CHILDREN IN PALERMO, ITALY
1989
The prevalence of IgG antibodies to Bordetella pertussis in a sample of 615 1-12-year-old unvaccinated children in Palermo was estimated by ELISA. The overall prevalence was 56%; it increased from 24% in one to three-year-old children to 67% in 11-12-year-old children (p less than 0.01). IgG antibody prevalence was not associated with the father's years of schooling (OR 1), nor with the family size (OR 1.3; C.I. 95% = 0.8-2.2). For children aged one the three years, serological results showed that the history of pertussis reported by parents in questionnaires gave high specificity (93.2%) and negative predictive value (85.4%). Our seroepidemiological study evidences a great exposure of chil…
Towards understanding the epidemiology of Neisseria meningitidis in the African meningitis belt: a multi-disciplinary overview
2016
International audience; Objectives: Neisseria meningitidis is the major cause of seasonal meningitis epidemics in the African meningitis belt. In the changing context of a reduction in incidence of serogroup A and an increase in incidence of serogroups W and C and of Streptococcus pneumoniae, a better understanding of the determinants driving the disease transmission dynamics remains crucial to improving bacterial meningitis control.Methods: The literature was searched to provide a multi-disciplinary overview of the determinants of meningitis transmission dynamics in the African meningitis belt.Results: Seasonal hyperendemicity is likely predominantly caused by increased invasion rates, spo…
Serological prevalence of toxoplasmosis in pregnant women in Luanda (Angola): Geospatial distribution and its association with socio-demographic and …
2020
We report a study on toxoplasmosis in pregnant women in Luanda, Angola, determining the seroprevalence, geospatial distribution and its association with socio-economic features, dietary habits and hygiene and health conditions. Anti-Toxoplasma gondii IgG and IgM were quantified in serum samples of women attended at the Lucrecia Paim Maternity Hospital between May 2016 and August 2017. The IgG avidity test and qPCR assay were used for dating the primary infection. Data were collected by questionnaire after written consent, and spatial distribution was assessed through a Kernel Density Function. The potential risk factors associated with Toxoplasma infection were evaluated using bivariate and…
Exposure to trihalomethanes through different water uses and birth weight, small for gestational age, and preterm delivery in Spain
2011
Background: Evidence associating exposure to water disinfection by-products with reduced birth weight and altered duration of gestation remains inconclusive. Objective: We assessed exposure to trihalomethanes (THMs) during pregnancy through different water uses and evaluated the association with birth weight, small for gestational age (SGA), low birth weight (LBW), and preterm delivery. Methods: Mother–child cohorts set up in five Spanish areas during the years 2000–2008 contributed data on water ingestion, showering, bathing, and swimming in pools. We ascertained residential THM levels during pregnancy periods through ad hoc sampling campaigns (828 measurements) and regulatory data (264 me…
