Prevalencia de parásitos intestinales en niños preescolares de barrios vulnerables de Bogotá

Introducción: Infecciones parasitarias intestinales (IPI) son enfermedades tropicales desatendidas, a pesar de que su prevalencia es alta en muchos países en desarrollo. El impacto en la salud pública de los IPI es importante, especialmente para los niños debido al efecto negativo sobre el crecimiento y el desarrollo. Objectivos: Este estudio examina la prevalencia y factores de riesgo de IPI en niños preescolares de barrios en riesgo, incluidos los de las familias desplazadas. Materiales y Métodos: estudio transversal entre 239 niños preescolares de dos barrios vulnerables de Bogotá. Se recogieron muestras fecales y se examinaron microscópicamente utilizando dos técnicas (directa y Ritchie). Se aplicó cuestionario para indagar factores relacionados con el parasitismo intestinal. Resultados: Se encontró una prevalencia de 26,4% de parásitos intestinales patógenos (Giardia duodenalis, Blastocystis spp, Trichuris trichiura, Ascaris lumbricoides y Hymenolepis nana). La regresión logística resultó en cuatro factores de riesgo: hermanos ?5 años (OR 2.33 [1.077-5.021]), los perros callejeros (OR 2.91 [0.867-9.767]), los ocupantes de la casa (OR 2.57 [1.155-5.706]) y el sexo del niño/a (OR 2.17 [1.022-4.615]). Discusión: La presencia del IPI en los niños preescolar es un problema de salud importante en Bogotá y que debe abordarse. Una alta prevalencia de protozoos se encontró comparado con helmintos. La implementación de políticas que aborden los factores de riesgo podría ser un primer paso en la disminución de la prevalencia del IPI. El antecedente de desplazamiento no cambio ni el tipo de parásito ni la prevalencia de parasitismo.Introduction: Intestinal parasitic infections (IPIs) are neglected tropical diseases, even though their prevalence is high in many developing countries. The public health impact of IPIs is substantial, in particular for children due to the negative effect on growth and development. Objectives: This study examines the prevalence and risk factors of IPIs in preschool-children from at-risk neighborhoods, including those from internally displaced families. Materials and Methods: A cross-sectional study among 239 preschool-children from two vulnerable neighborhoods in Bogotá. Fecal samples were collected and microscopically examined (direct and Ritchie technique) and data regarding related factors was obtained through a questionnaire. Results: A prevalence of 26.4% for pathogenic parasites (Giardia duodenalis, Blastocystis spp, Trichuris trichiura, Ascaris lumbricoides, and Hymenolepis nana) was found. Logistic regression resulted in four risk factors: siblings ?5 years (OR 2.33 [1.077-5.021]), stray dogs (OR 2.91 [0.867-9.767]), household members (OR 2.57 [1.155-5.706]) and child's sex (OR 2.17 [1.022-4.615]). Discussion: IPI presence in preschool children is an important health issue in Bogotá which should be addressed. A high protozoan prevalence was found compared to helminthes. Implementing policies addressing risk factors could be a first step in decreasing IPI prevalenc

Social cohesion, social trust, social participation and sexual behaviors of adolescents in rural Tanzania

Abstract Background Social cohesion, defined as a glue holding society together, has been found to influence several aspects of human behavior. Social cohesion, being composed of social trust and social participation, is a social factor that may influence sexual behaviors. Unfortunately, studies investigating the influence of social cohesion on sexual behaviors among young people are scarce. This study examined the influence of social cohesion on safe sexual behavior among adolescents in rural Tanzania. Methods A cross-sectional study was conducted among 403 school adolescents of the Newala district, between May and August 2010. Socio-demographic characteristics, social cohesion (social trust and social participation) and sexual behavior (age at sexual debut, intention to use and reported condom use, number of sexual partners) were obtained through self-administered questionnaires. Data analysis was performed using descriptive statistics and binary logistic regression. Results Sexual debut at under 13 years of age was reported by 12% of the respondent. A majority (71%) reported multiple sexual partnerships and half of the participants reported to have used a condom at their last sexual encounter. The intention to use a condom was reported by 77% of the respondents. Having multiple sexual partnerships was associated with social trust only (odds ratio: 3.5, 95% CI 1.01–12.3) whereas reported condom use was related with social cohesion (odds ratio 4.8 95% CI 1.66–14.06). Social cohesion, trust or participation was not associated with young age at sexual debut or intention to use a condom. Being a female (odds ratio 2.07 95% CI 1.04–4.12.) was associated with intention to use a condom. Conclusion This study indicates that social cohesion and socio-demographic factors influence actual behavior performance and behavioral intentions. The findings point to the importance of collecting more evidence on social cohesion and sexual behaviors in different settings and designing interventions that enhance social cohesion among adolescents in order to reinforce positive sexual behaviors

Item Response Theory Applied to Factors Affecting the Patient Journey Towards Hearing Rehabilitation

To develop a tool for use in hearing screening and to evaluate the patient journey towards hearing rehabilitation, responses to the hearing aid rehabilitation questionnaire scales aid stigma, pressure, and aid unwanted addressing respectively hearing aid stigma, experienced pressure from others; perceived hearing aid benefit were evaluated with item response theory. The sample was comprised of 212 persons aged 55 years or more; 63 were hearing aid users, 64 with and 85 persons without hearing impairment according to guidelines for hearing aid reimbursement in the Netherlands. Bias was investigated relative to hearing aid use and hearing impairment within the differential test functioning framework. Items compromising model fit or demonstrating differential item functioning were dropped. The aid stigma scale was reduced from 6 to 4, the pressure scale from 7 to 4, and the aid unwanted scale from 5 to 4 items. This procedure resulted in bias-free scales ready for screening purposes and application to further understand the help-seeking process of the hearing impaired
