Community social capital on the timing of sexual debut and teen birth in Nicaragua: a multilevel approach.

BACKGROUND: Community attributes have been gradually recognized as critical determinants shaping sexual behaviors in young population; nevertheless, most of the published studies were conducted in high income countries. The study aims to examine the association between community social capital with the time to sexual onset and to first birth in Central America. METHODS: Building upon the 2011/12 Demographic and Health Survey conducted in Nicaragua, we identified a sample of 2766 community-dwelling female adolescents aged 15 to 19 years. Multilevel survival analyses were performed to estimate the risks linked with three domains of community social capital (i.e., norms, resource and social network). RESULTS: Higher prevalence of female sexual debut (norms) and higher proportion of secondary school or higher education (resource) in the community are associated with an earlier age of sexual debut by 47 % (p < 0.05) and 16 %, respectively (p < 0.001). Living in a community with a high proportion of females having a child increases the hazard of teen birth (p < 0.001) and resource is negatively associated with teen childbearing (p < 0.05). Residential stability and community religious composition (social network) were not linked with teen-onset sex and birth. CONCLUSIONS: The norm and resource aspects of social capital appeared differentially associated with adolescent sexual and reproductive behaviors. Interventions aiming to tackle unfavorable sexual and reproductive outcomes in young people should be devised and implemented with integration of social process.

Comorbidity of Atopic Disorders with Autism Spectrum Disorder and Attention Deficit/Hyperactivity Disorder.

OBJECTIVE: To assess the relationship between allergic manifestations in early life and the occurrence of newly diagnosed autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD) throughout childhood. STUDY DESIGN: We collected a population-based longitudinal cohort comprising children enrolled in Taiwan's National Health Insurance Program during 2000-2010. We first identified 387,262 children who had a diagnosis of atopic dermatitis (AD) before age 2 years, with 1:1 individualized matching to children without AD. Cox regression analyses were performed to estimate the early-onset and cumulative effects of allergic manifestations on ASD and ADHD. RESULTS: An estimated 0.5% of AD-exposed children received a diagnosis of ASD, and 3.7% were diagnosed with ADHD, significantly higher than the respective rates of 0.4% and 2.9% found in their nonexposed peers. Having AD before age 2 years was associated with an increased hazard ratio (HR) for ASD by 10% and that for ADHD by 16%; such increases were particularly prominent among those with earlier-onset or more severe AD. HRs were especially higher for children with persistent AD and emerging atopic respiratory diseases in childhood (eg, for ASD, adjusted HR, 1.75 and 2.13, respectively; P < .001). CONCLUSION: The observed increased risks of ASD and ADHD associated with AD in infancy suggest that a disordered immunologic response may exert effects on neurodevelopment and have implications for research into etiology and treatment strategies.

Increased risks of congenital, neurologic, and endocrine disorders associated with autism in preschool children: cognitive ability differences.

OBJECTIVE: To investigate the increased risk of congenital, neurologic, and endocrine disorders in autistic preschool children and to probe possible cognitive impairment-associated variation in such risks. STUDY DESIGN: Using a population-based longitudinal study, a total of 3440 autistic children born in 1997-1999 and 33,391 age- and residential urbanicity-matched control subjects were identified from the National Health Insurance Research Database in Taiwan. Conditional logistic analyses were performed to estimate the strength of association stratified by the presence of cognitive impairment. RESULTS: Autistic children were found to have greatly elevated risks of congenital anomalies (eg, tuberous sclerosis: adjusted odds ratio [aOR] = 34 approximately 61) and neurologic disorders (eg, epilepsy: aOR = 5 approximately 13) compared with their matched nonautistic peers. The increased risk of medical diseases for mentally retarded autism were approximately 1.6 to 9 times greater than those for isolated autism. CONCLUSIONS: The observed cognitive impairment-related variation in the increased risk of congenital, neurological, and endocrine disorders with autism may provide some clinical and etiologic implications that warrant investigation in the future.

The PACARDO research project: youthful drug involvement in Central America and the Dominican Republic.

OBJECTIVE: To estimate the occurrence and school-level clustering of drug involvement among school-attending adolescent youths in each of seven countries in Latin America, drawing upon evidence from the PACARDO research project, a multinational collaborative epidemiological research study. METHODS: During 1999-2000, anonymous self-administered questionnaires on drug involvement and related behaviors were administered to a cross-sectional, nationally representative sample that included a total of 12,797 students in the following seven countries: Costa Rica (n = 1,702), the Dominican Republic (n = 2,023), El Salvador (n = 1,628), Guatemala (n = 2,530), Honduras (n = 1,752), Nicaragua (n = , 419), and Panama (n = 1,743). (The PACARDO name concatenates PA for Panamá, CA for Centroamérica, and RDO for República Dominicana). Estimates for exposure opportunity and actual use of alcohol, tobacco, inhalants, marijuana, cocaine (crack/coca paste), amphetamines and methamphetamines, tranquilizers, ecstasy, and heroin were assessed via responses about questions on age of first chance to try each drug, and first use. Logistic regression models accounting for the complex survey design were used to estimate the associations of interest. RESULTS: Cumulative occurrence estimates for alcohol, tobacco, inhalants, marijuana, and illegal drug use for the overall sample were, respectively: 52%, 29%, 5%, 4%, and 5%. In comparison to females, males were more likely to use alcohol, tobacco, inhalants, marijuana, and illegal drugs; the odds ratio estimates were 1.3, 2.1, 1.6, 4.1, and 3.2, respectively. School-level clustering was noted in all countries for alcohol and tobacco use; it was also noted in Costa Rica, El Salvador, Guatemala, and Panama for illegal drug use. CONCLUSIONS: This report sheds new light on adolescent drug experiences in Panama, the five Spanish-heritage countries of Central America, and the Dominican Republic, and presents the first estimates of school-level clustering of youthful drug involvement in these seven countries. Placed in relation to school survey findings from North America and Europe, these estimates indicate lower levels of drug involvement in these seven countries of the Americas. For example, in the United States of America 70% of surveyed youths had tried alcohol and 59% had smoked tobacco. By comparison, in these seven countries, only 51% have tried alcohol and only 29% have smoked tobacco. Future research will help to clarify explanations for the observed variations across different countries of the world. In the meantime, strengthening of school-based and other prevention efforts in the seven-country PACARDO area may help these countries slow the spread of youthful drug involvement, reduce school-level clustering, and avoid the periodic epidemics of illegal drug use that have been experienced in North America.

The PACARDO research project: youthful drug involvement in Central America and the Dominican Republic / Proyecto de investigación PACARDO: el consumo de drogas entre la juventud en Centroamérica y la República Dominicana

OBJETIVO: Estimar el grado en que el consumo de drogas se produce y muestra una concentración en el nivel escolar entre adolescentes que asisten a la escuela en siete países de América Latina. Los datos presentados provienen del proyecto de investigación PACARDO, estudio epidemiológico conjunto multinacional. MÉTODOS: En el período de 1999­2000, se aplicaron cuestionarios anónimos autoadministrados sobre el consumo de drogas y conductas afines a una muestra transversal, representativa de la población nacional, que se compuso de un total de 12 797 estudiantes en los siguientes siete países: Costa Rica (n> 1 702), El Salvador (n> 1 628), Guatemala (n> 2 530), Honduras (n> 1 752), Nicaragua (n> 1 419), República Dominicana (n> 2 023) y Panamá (n> 1 743). (El nombre de PACARDO combina la PA de Panamá, la CA de Centroamérica y la RDO de República Dominicana). Se calcularon las oportunidades de exposición y el consumo de alcohol, tabaco, sustancias inhaladas, marijuana, cocaína (crack/pasta de cocaína), anfetaminas y metaanfetaminas, tranquilizantes, éxtasis y heroína sobre la base de las respuestas dadas a preguntas acerca de la edad en que se tuvo la oportunidad de probar cada una de las drogas, y en que se probó cada una de ellas, por primera vez. Para estimar las asociaciones de interés se aplicaron modelos de regresión logística con arreglo a la complejidad de la encuesta. RESULTADOS: Las siguientes fueron las frecuencias estimadas acumulativas del consumo de alcohol, tabaco, sustancias inhaladas, marijuana y drogas, respectivamente, en toda la muestra: 52%, 29%, 5%, 4% y 5%. Comparados con las mujeres, los varones fueron más propensos a consumir alcohol, tabaco, sustancias inhaladas, marijuana y drogas; las razones de posibilidades estimadas fueron, respectivamente, 1,3; 2,1; 1,6; 4,1 y 3,2. En todos los países se observó una concentración del consumo de alcohol y tabaco en el nivel escolar; el consumo ilegal de drogas también mostró una concentración escolar en Costa Rica, El Salvador, Guatemala y Panamá. CONCLUSIONES: Este informe arroja nueva luz sobre las experiencias de los adolescentes con la droga en Panamá, en los cinco países centroamericanos de tradición española, y en la República Dominicana. En él se presentan las primeras estimaciones del grado en que se concentra en las escuelas el consumo de drogas entre la juventud de estos siete países. Cuando se examinan a la luz de los resultados de encuestas escolares...
