Análisis sociológico de los factores de riesgo sexual en la población universitaria. Un estudio comparativo

Objetivo principal: El objetivo de la presente investigación es identificar los factores de riesgo sexual y su relación con la estructura familiar de la que forman parte los estudiantes universitarios según el grado que cursan. Metodología: Se aplicó un cuestionario a 220 alumnos de los dos títulos de grado de la Universidad de Alicante (España). Resultados principales: Los resultados muestran que el 70.1% de los estudiantes se inició en la sexualidad entre los 16-18 años. El 95.5% ha utilizado métodos anticonceptivos en su primera relación sexual. Los estudiantes de enfermería recibieron la información sexual a través de los centros educativos y los estudiantes de Administración y Dirección de Empresas (ADE) la obtuvieron de los amigos. Conclusión principal: Se concluye que en la población universitaria siguen presentes conductas que conllevan riesgos para la salud, no encontrándose influenciados por la estructura familiar de origen. Actualmente, existe cierta disociación entre la información que reciben los estudiantes y las conductas inseguras que llevan a cabo.

Psychometric behaviour of the strengths and difficulties questionnaire (SDQ) in the Spanish national health survey 2006

Background: The Strengths and Difficulties Questionnaire (SDQ) is a tool to measure the risk for mental disorders in children. The aim of this study is to describe the diagnostic efficiency and internal structure of the SDQ in the sample of children studied in the Spanish National Health Survey 2006. Methods: A representative sample of 6,773 children aged 4 to 15 years was studied. The data were obtained using the Minors Questionnaire in the Spanish National Health Survey 2006. The ROC curve was constructed and calculations made of the area under the curve, sensitivity, specificity and the Youden J indices. The factorial structure was studied using models of exploratory factorial analysis (EFA) and confirmatory factorial analysis (CFA). Results: The prevalence of behavioural disorders varied between 0.47% and 1.18% according to the requisites of the diagnostic definition. The area under the ROC curve varied from 0.84 to 0.91 according to the diagnosis. Factor models were cross-validated by means of two different random subsamples for EFA and CFA. An EFA suggested a three correlated factor model. CFA confirmed this model. A five-factor model according to EFA and the theoretical five-factor model described in the bibliography were also confirmed. The reliabilities of the factors of the different models were acceptable (>0.70, except for one factor with reliability 0.62). Conclusions: The diagnostic behaviour of the SDQ in the Spanish population is within the working limits described in other countries. According to the results obtained in this study, the diagnostic efficiency of the questionnaire is adequate to identify probable cases of psychiatric disorders in low prevalence populations. Regarding the factorial structure we found that both the five and the three factor models fit the data with acceptable goodness of fit indexes, the latter including an externalization and internalization dimension and perhaps a meaningful positive social dimension. Accordingly, we recommend studying whether these differences depend on sociocultural factors or are, in fact, due to methodological questions.

Prácticas de autocuidado sexual y reproductivo en mujeres “parejas de” migrantes internacionales de San Luis Potosí, México

Los migrantes y sus parejas han sido incorporados en los discursos institucionales de salud como “sujetos en riesgo” frente a las Infecciones de Trasmisión Sexual (ITS), sin embargo la incorporación de esta población específica en la comunicación y gestión del riesgo de ITS ha sido ambigua en el contexto mexicano. El objetivo del presente acercamiento fue conocer las prácticas de autocuidado sexual y reproductivo que adoptan en su cotidianeidad mujeres parejas de migrantes y la relación de dichas medidas con la comunicación y gestión del riesgo que los Servicios de Salud realizan. Se trató de una aproximación de tipo cualitativo con 20 mujeres “de migrantes” localizadas mediante los servicios de salud, la información se recabó a través de entrevistas a profundidad que focalizaron en las esferas de “percepción del riesgo” y “Autocuidado sexual y reproductivo”. Se encontró que la mayoría de las mujeres no se reconoce vulnerable frente a las ITS y que la percepción del riesgo no es determinante en la confrontación que respecto a la amenaza puedan desarrollar, dado que los imaginarios patriarcales que prevalecen en ellas, sus parejas y el personal de salud desestiman la utilización de medidas de prevención y detección oportuna.

Distortion of self-image: risk factor for obesity in children and teenagers

Introduction: Self-image is important in the behaviour and lifestyle of children and adolescents. Analysing the self-image they have and the factors that might influence their distortion, can be used to prevent problems of obesity and anorexia. The main objective of present publication was to analyse the risk factors that may contribute to self-image distortion. Material and Methods: A descriptive survey study was conducted among 659 children and adolescents in two social classes (low and medium-high), measuring height and weight, calculating BMI percentile for age and gender. Body image and self-perception were registered. Results: The percentage of overweight-obesity is higher in scholars (41.8% boys, 28.7% girls) than in adolescents (30.1% and 22.2% respectively), with no difference between socioeconomic classes. The multinomial logistic regression analysis gives a risk of believing thinner higher (p=0.000) among boys OR=2.9(95%CI:1.43-3.37), school (p=0.000) OR=2.42(95%CI:1.56-3.76) and much lower (p=0.000) between normally nourished OR=0.08(95%CI:0.05-0.13), with no differences according to socioeconomic status. The risk of believing fatter is lower (p=0.000) between boys OR=0.28(95%CI:0.14-0.57), school(p=0.072) OR=0.54(95%CI:0.27-1.6), and much higher among underweight (p=0.000) OR=9x108(95% CI:4x108-19x108). Conclusions: Are risk factors of believing thinner: males, being in a group of schoolchildren and overweight-obesity. Conversely, are risk factors of believing fatter: females, teen and above all, be thin.
