Regional Disparities in Sedentary Behaviors and Meal Frequency in Iranian Adolescents: The CASPIAN-III Study

Background: The prevalence of obesity is increasing among Iranian youngsters like other developing countries. Objectives: This study was conducted to assess regional disparities in sedentary behaviors and meal frequency in Iranian adolescents. Patients and Methods: In this national survey, 5682 students aged 10 - 18 years from urban and rural districts of 27 provinces of Iran were selected via stratified multi-stage sampling method. The country was classified into four sub-national regions, based on criteria of the combination of geography and socioeconomic status (SES). Mean of meal frequency and physical activity levels as well as prevalence of omitting meals and sedentary behavior were compared across regions with different SES after stratifying with sex and age group. Results: Meal frequency in lower socio-economic regions was significantly higher than two other regions in 10 - 13 and 10 - 18 years old groups (P trend < 0.001). However, the mean of working hours with computer was linearly increased with increasing the SES in studied regions (P trend < 0.001), whereas the corresponding figure was not significant for the mean of watching TV (P trend > 0.05). Frequency of adolescents omitting their meals was higher in higher SES regions especially in West Iran (P < 0.001) in 10 - 13 years old age group. Having personal computer and working with it more than two hours per day mainly was observed in central Iran which ranked as the highest SES group. Conclusions: Efforts to ensure Iranian youth meet healthy food habits and screen time guidelines include limiting access to screen technologies and encouraging parents to monitor their own screen time is required.

Association of body composition indices with insulin resistance in European adolescents: the HELENA study

Background: The different body components may contribute to the development of insulin resistance and type 2 diabetes mellitus. The aim of the present study was to examine the association of fat mass and fat free mass indices with markers of insulin resistance, independently of each other and giving, at the same time, gender-specific information in a wide cohort of European adolescents. Methods: A cross-sectional study in a school setting was conducted in 925 (430 males) adolescents (14.9 ± 1.2 years). Weight, height, anthropometric, bioimpedance and blood parameters were measured. Indices for fat mass and fat free mass, and homeostatic model assessment (HOMA) were calculated. Multiple regression analyses were performed adjusting for several confounders including fat free mass and fat mass when possible. Results: Indices of fat mass were positively associated with HOMA (all p < 0.01) after adjusting for all the confounders including fat free mass indices, in both sexes. Fat free mass indices were associated with HOMA, in both males and females, after adjusting for center, pubertal status, socioeconomic status and cardiorespiratory fitness, but the associations disappear when including fat mass indices in the adjustment's model. Conclusion: Fat mass indices derived from different methods are positively associated with insulin resistance independently of several confounders including fat free mass indices. In addition, the relationship of fat free mass with insulin resistance is influenced by the amount of fat mass in European adolescents. Nevertheless, future studies should focus not only on the role of fat mass, but also on other body components such as fat free mass because its role could vary depending of the level and distribution of fat mass.

Body image dissatisfaction and low self-esteem due to physical appeareance in students of the faculty of medicine at the university of los andes (mérida, venezuela)

The purpose of this investigation was to evaluate body image dissatisfaction in relation to low self-esteem due to physical appearance in students of the Faculty of Medicine at the University of Los Andes in Mérida, Venezuela.  It was a non-experimental and correlational study.  The sample included 189 students (27% male and 73% female) with an average age of 19.58 ± 1.57 (men: 19.81 years of age ± 1.74 and women: 20.24 years of age ± 1.76).  Participants were intentionally selected from first-year courses of the Medicine, Nursing and Nutrition programs.  The Body Shape Questionnaire (BSQ) (Cooper and Taylor, 1987) was the instrument used to measure body image dissatisfaction and Graffar’s modified method (Méndez and De Méndez, 1994) was applied to determine the participants’ socioeconomic status.  A descriptive analysis (frequency, percentages, mean) and an inferential analysis (one-way ANOVA) were applied to the data using SPSS (Statistical Package for Social Sciences) version 9.0.  One of the most important findings in this study was the determination of a statistically significant relationship between dissatisfaction and body image and between low self-esteem and gender χ2 (2, N= 189) = 9.686, p=0.008.  Using ANOVA also helped determine that differences in the mean for dissatisfaction and low self-esteem levels with body image and gender are statistically significant, F= 11.236; p=0.008, F=10.23; p=0.002, respectively.  Conclusions: results obtained suggest a relationship between dissatisfaction and low self-esteem due to physical appearance. Consequently, subjects reject their body image because of a distorted or undistorted perception of their physical appearance, which can possibly affect self-esteem.  Moreover, it is observed that the students’ psychological health is more related to their satisfaction with their body-image than to the way their body image is perceived. Consequently, this group of participants must be analyzed regarding their self-esteem due to body image, as an expression in the institutional environment.  It is also important to emphasize that gender may be a risk factor concerning eating disorders.  We believe the foregoing because women showed higher dissatisfaction levels because of their physical appearance being conditioned by a higher dissatisfaction with their perceived body image, which is characterized by an overestimation of the physical dimension of their body image.

Correlación del estado socioeconómico con los conocimientos de lactancia materna en embarazadas que acuden a los subcentros de salud de Totoracocha, el Paraíso y Pumapungo, Cuenca 2015

Introducción: la lactancia materna ayuda al desarrollo del niño, además brinda beneficios a la madre, familia, sociedad; siendo su desconocimiento un problema de salud pública. Objetivo: determinar la correlación entre el conocimiento de la lactancia materna y el estado socioeconómico de las gestantes que acuden a los subcentros de salud Totoracocha, El Paraíso y Pumapungo, Cuenca 2015. Metodología: se realizó una encuesta a 170 gestantes, recogiendo datos referentes al estado económico y una evaluación del conocimiento en el tema; para el análisis de los datos se trabajó con el programa estadístico SPSS 15, utilizando los estadísticos de prueba respectivos. Resultados: la edad media fue de 25.3 años, de las cuales el 41,8% son casadas, la mayor parte de madres tienen embarazos previos, el 54,7% de las madres son amas de casa, la gran parte poseen un nivel socioeconómico medio bajo (44,7%); el 90% tuvo conocimientos insuficientes, y no existió correlación entre el conocimiento en lactancia materna y el nivel socioeconómico. El nivel de conocimiento de lactancia materna en las primigestas y adolecentes es menor que las multigestas y grupos de edad mayor respectivamente. Conclusiones: de entre las madres que acuden a los centros de salud de Totoracocha, El Paraiso y Pumapungo el estatus social de la madre gestante no mide su nivel de conocimiento en lactancia materna, así las líneas de acción deberían regirse a proporcionar información suficiente y de calidad a toda la población sin distinción de condiciones

Self-reported vaccination in the elderly : SABE Bogotá study, Colombia

Objectives: To determine the frequency of vaccination in older adults within the city of Bogotá and to estimate the association with sociodemographic and health factors. Methods: This is a secondary data analysis from the SABE-Bogotá Study, a cross-sectional population-based study that included a total of 2,000 persons aged 60 years. Weighted percentages for self-reported vaccination [influenza, pneumococcal, tetanus] were determined. The association between vaccination and covariates was evaluate by logistic regression models. Results: A total of 73.0% of respondents received influenza, 57.8% pneumococcal and 47.6% tetanus vaccine. Factors independently associated with vaccination included: 1- age (65-74 years had higher odds of receiving vaccinations, compared to 60-64 years; 2- socioeconomic status (SES) (higher SES had lower odds of having influenza and pneumococcal vaccines, compared to those with lower SES); 3- health insurance (those with contributive or subsidized health insurance had higher odds (between 3 and 5 times higher) of having vaccinations, compared to those with no insurance); 4- older adults with better functional status (greater Lawton scores) had increased odds for all vaccinations; 5- older adults with higher comorbidity had increased odds for influenza and pneumococcal vaccinations. Conclusion: Vaccination campaigns should be strengthened to increase vaccination coverage, especially in the group more reticent to vaccination or vulnerable to reach it such as the disable elder.

A Longitudinal Exploration of the Relationship Between Oral Reading Fluency and Reading Comprehension Achievement Among a Sample of Diverse Young Learners

Exploring the relationship between early oral reading fluency ability and reading comprehension achievement among an ethnically and racially diverse sample of young learners from low-income families, attending elementary school within a large public school district in southeast Florida is the purpose of this longitudinal study. Although many studies have been conducted to address the relationship between oral reading fluency ability and reading comprehension achievement, most of the existing research failed either to disaggregate the data by demographic subgroups or secure a large enough sample of students to adequately represent the diverse subgroups. The research questions that guided this study were: (a) To what extent does early oral reading fluency ability measured in first, second, or third grade correlate with reading comprehension achievement in third grade? (b) To what extent does the relationship of early oral reading fluency ability and reading comprehension achievement vary by demographic subgroup membership (i.e., gender, race/ethnicity, socioeconomic status) among a diverse sample of students? A predictive research design using archived secondary data was employed in this nonexperimental quantitative methods study of 1,663 third grade students who attended a cohort of 25 Reading First funded schools. The data analyzed derived from the Dynamic Indicators of Basic Early Literacy Skills Oral Reading Fluency (DIBELS ORF) measure administered in first, second, and third grades and the Florida Comprehensive Assessment Test of the Sunshine State Standards (FCAT-SSS) Reading administered in third grade. Linear regression analyses between each of the oral reading fluency and reading comprehension measures produced significant positive correlations. Hierarchical regression analyses supported the predictive potential of all three oral reading fluency ability measures toward reading comprehension achievement, with the first grade oral reading fluency ability measure explaining the most significant variance in third grade reading comprehension achievement. Male students produced significant overall differences in variance when compared to female students as did the Other student subgroup (i.e., Asian, Multiracial, and Native American) when compared to Black, White, and Hispanic students. No significant differences in variance were produced between students from low and moderate socioeconomic families. These findings are vital toward adding to the literature of diverse young learners.

The Influence of HOPE VI Public Housing on Public Schools

In the United States, public school enrollment is typically organized by neighborhood boundaries. This dissertation examines whether the federally funded HOPE VI program influenced performance in neighborhood public schools. In effect since 1992, HOPE VI has sought to revitalize distressed public housing using the New Urbanism model of mixed income communities. There are 165 such HOPE VI projects nationwide. Despite nearly two decades of the program’s implementation, the literature on its connection to public school performance is thin. My dissertation aims to narrow this research gap. There are three principal research questions: (1) Following HOPE VI, was there a change in socioeconomic status (SES) in the neighborhood public school? The hypothesis is that low SES (measured as the proportion of students qualifying for the Free and Reduced Lunch Program) would reduce. (2) Following HOPE VI, did the performance of neighborhood public schools change? The hypothesis is that the school performance, measured by the proportion of 5th grade students proficient in state wide math and reading tests, would increase. (3) What factors relate to the performance of public schools in HOPE VI communities? The focus is on non-school, neighborhood factors that influence the public school performance. For answering the first two questions, I used t-tests and regression models to test the hypotheses. The analysis shows that there is no statistically significant change in SES following HOPE VI. However, there are statistically significant increases in performance for reading and math proficiency. The results are interesting in indicating that HOPE VI neighborhood improvement may have some relationship with improving school performance. To answer the third question, I conducted a case study analysis of two HOPE VI neighborhood public schools, one which improved significantly (in Philadelphia) and one which declined the most (in Washington DC). The analysis revealed three insights into neighborhood factors for improved school performance: (i) a strong local community organization; (ii) local community’s commitment (including the middle income families) to send children to the public school; and (iii) ties between housing and education officials to implement the federal housing program. In essence, the study reveals how housing policy is de facto education policy.

The Influence of Gender on Perceived Treatment Need among a Community Sample of Substance Users

Purpose: Most individuals do not perceive a need for substance use treatment despite meeting diagnostic criteria for substance use disorders and they are least likely to pursue treatment voluntarily. There are also those who perceive a need for treatment and yet do not pursue it. This study aimed to understand which factors increase the likelihood of perceiving a need for treatment for individuals who meet diagnostic criteria for substance use disorders in the hopes to better assist with more targeted efforts for gender-specific treatment recruitment and retention. Using Andersen and Newman’s (1973/2005) model of individual determinants of healthcare utilization, the central hypothesis of the study was that gender moderates the relationship between substance use problem severity and perceived treatment need, so that women with increasing problems due to their use of substances are more likely than men to perceive a need for treatment. Additional predisposing and enabling factors from Andersen and Newman’s (1973/2005) model were included in the study to understand their impact on perceived need. Method: The study was a secondary data analysis of the 2010 National Survey on Drug Use and Health (NSDUH) using logistic regression. The weighted sample consisted of a total 20,077,235 American household residents (The unweighted sample was 5,484 participants). Results of the logistic regression were verified using Relogit software for rare events logistic regression due to the rare event of perceived treatment need (King & Zeng, 2001a; 2001b). Results: The moderating effect of female gender was not found. Conversely, men were significantly more likely than women to perceive a need for treatment as substance use problem severity increased. The study also found that a number of factors such as race, ethnicity, socioeconomic status, age, marital status, education, co-occurring mental health disorders, and prior treatment history differently impacted the likelihood of perceiving a need for treatment among men and women. Conclusion: Perceived treatment need among individuals who meet criteria for substance use disorders is rare, but identifying factors associated with an increased likelihood of perceiving need for treatment can help the development of gender-appropriate outreach and recruitment for social work treatment, and public health messages.

A multidimensionalidade da adaptação escolar na pré-adolescência

A presente investigação procura fomentar a reflexão e a compreensão do fenómeno da adaptação escolar. Partindo da exploração da literatura e de um conjunto de pressupostos teóricos de ordem desenvolvimental e ecológica, foi concetualmente delineado e testado um modelo multidimensional de adaptação escolar na pré-adolescência. O modelo examina principalmente dimensões sociais, mas também a dimensão académica e o nível socioeconómico familiar, propondo uma visão integrada da adaptação escolar. O estudo empírico desenvolveu-se junto de 706 estudantes pré-adolescentes e avaliou as perceções do próprio estudante e as perceções dos professores e pares acerca da competência social dos estudantes. O teste empírico ao Modelo de Adaptação Escolar evidencia um ajustamento global razoável, suportando as associações preconizadas entre as componentes da competência social e entre estas componentes sociais e a realização académica e o nível socioeconómico e cultural da família. Estes resultados sublinham a necessidade de considerar múltiplas facetas na avaliação e promoção da adaptação escolar, reconhecendo-se que esta engloba especialmente conexões entre a competência social e realização académica do estudante. Estes resultados serão ainda alvo de reflexão e discussão, sendo extraídas implicações para a investigação, teoria e intervenção.

Change, stability and prediction of gross motor co-ordination in portuguese children

The knowledge about intra- and inter-individual variation can stimulate attempts at description, interpretation and prediction of motor co-ordination (MC). Aim: To analyse change, stability and prediction of motor co-ordination (MC) in children. Subjects and methods: A total of 158 children, 83 boys and 75 girls, aged 6, 7 and 8 years, were evaluated in 2006 and re-evaluated in 2012 at 12, 13 and 14 years of age. MC was assessed through the Kiphard-Schilling’s body co-ordination test and growth, skeletal maturity, physical fitness, fundamental motor skills (FMS), physical activity and socioeconomic status (SES) were measured and/or estimated. Results: Repeated-measures MANOVA indicated that there was a significant effect of group, sex and time on a linear combination of the MC tests. Univariate tests revealed that group 3 (8–14 years) scored significantly better than group 1 (6–12 years) in all MC tests and boys performed better than girls in hopping for height and moving sideways. Scores in MC were also higher at follow-up than at baseline. Inter-age correlations for MC were between 0.15–0.74. Childhood predictors of MC were growth, physical fitness, FMS, physical activity and SES. Biological maturation did not contribute to prediction of MC. Conclusion: MC seemed moderately stable from childhood through adolescence and, additionally, inter-individual predictors at adolescence were growth, FMS, physical fitness, physical activity and SES.

The potential of symbolic approximation. Disentangling the effects of approximation vs. calculation demands in nonsymbolic and symbolic representations.

Mathematical skills that we acquire during formal education mostly entail exact numerical processing. Besides this specifically human faculty, an additional system exists to represent and manipulate quantities in an approximate manner. We share this innate approximate number system (ANS) with other nonhuman animals and are able to use it to process large numerosities long before we can master the formal algorithms taught in school. Dehaene´s (1992) Triple Code Model (TCM) states that also after the onset of formal education, approximate processing is carried out in this analogue magnitude code no matter if the original problem was presented nonsymbolically or symbolically. Despite the wide acceptance of the model, most research only uses nonsymbolic tasks to assess ANS acuity. Due to this silent assumption that genuine approximation can only be tested with nonsymbolic presentations, up to now important implications in research domains of high practical relevance remain unclear, and existing potential is not fully exploited. For instance, it has been found that nonsymbolic approximation can predict math achievement one year later (Gilmore, McCarthy, & Spelke, 2010), that it is robust against the detrimental influence of learners´ socioeconomic status (SES), and that it is suited to foster performance in exact arithmetic in the short-term (Hyde, Khanum, & Spelke, 2014). We provided evidence that symbolic approximation might be equally and in some cases even better suited to generate predictions and foster more formal math skills independently of SES. In two longitudinal studies, we realized exact and approximate arithmetic tasks in both a nonsymbolic and a symbolic format. With first graders, we demonstrated that performance in symbolic approximation at the beginning of term was the only measure consistently not varying according to children´s SES, and among both approximate tasks it was the better predictor for math achievement at the end of first grade. In part, the strong connection seems to come about from mediation through ordinal skills. In two further experiments, we tested the suitability of both approximation formats to induce an arithmetic principle in elementary school children. We found that symbolic approximation was equally effective in making children exploit the additive law of commutativity in a subsequent formal task as a direct instruction. Nonsymbolic approximation on the other hand had no beneficial effect. The positive influence of the symbolic approximate induction was strongest in children just starting school and decreased with age. However, even third graders still profited from the induction. The results show that also symbolic problems can be processed as genuine approximation, but that beyond that they have their own specific value with regard to didactic-educational concerns. Our findings furthermore demonstrate that the two often con-founded factors ꞌformatꞌ and ꞌdemanded accuracyꞌ cannot be disentangled easily in first graders numerical understanding, but that children´s SES also influences existing interrelations between the different abilities tested here.

The influence of nursing student characteristics on performance in the Quebec licensing exam.

This study examines whether certain academic, demographic or psychosocial characteristics of students can be indicators of future success on the Provincial Nursing Licensing exam. A cohort of 42 third year Nursing students was the study sample. Data were collected using a self-reporting questionnaire, academic marks, and graduate interviews. Academic variables that were studied included: first year nursing marks, college biology marks, final year nursing marks, and literacy level. Demographic variables that were studied included : age, gender, socioeconomic status and level of life responsabilities, academic motivation (hours spent studying) and hours worked at unrelated employment. Lastly, psychosocial variables that were studied included: test taking anxiety, stress and overall confidence level in terms of success on the upcoming exam. A comparison was then undertaken between the two groups-students that passed and students that failed the Licensing exam on their first sitting-with respect to specific student characteristics. The conceptual framework for this study is based on Leinbach and Jenkin's model of the correlation of milestones to momentum points in the educational experience. Results of this study suggest that exam anxiety and content review in the months that follow graduation seem to affect exam performance. Also, certain demographic characteristics such as age and financial strain seemed to be good indicators of future success.||Résumé : Cette étude tente d'établir si certaines caractéristiques liées aux études ainsi que des caractéristiques démographiques ou psychosociales des étudiantes et des étudiants peuvent être indicatives du succès futur à l'examen professionnel provincial d'admission à la profession infirmière. Une cohorte de 42 étudiantes et étudiants de troisième année en sciences infirmières formait l'échantillon de l'étude. Les données ont été recueillies au moyen d'un questionnaire d'autoévaluation, des résultats scolaires et d'entrevues avec les infirmières et infirmiers gradués. Les variables liées aux études examinées ont été les résultats de la première année d'études en sciences infirmières, les résultats en biologie au collégial, les résultats de la dernière année d'études en sciences infirmières et le niveau de littératie. Les variables démographiques étudiées ont été l'âge, le sexe, le statut socioéconomique, le niveau de responsabilités sociales, la motivation dans les études (les heures passées à étudier) et les heures consacrées à un travail non lié aux études. Enfin, les variables psychosociales examinées ont été l'anxiété devant l'examen, le stress et le niveau général de confiance quant à la réussite de l'examen à venir. Une comparaison des deux groupes d'étudiantes et d'étudiants, soit ceux qui ont réussi l'examen et ceux qui l'ont échoué à leur première tentative, a ensuite été faite en tenant compte des caractéristiques particulières à chacun. Le cadre conceptuel de cette étude repose sur le modèle de la corrélation entre les jalons (milestones) et les accomplissements (momentum points) dans l'expérience des études de Leinbach and Jenkin. Les résultats de cette étude laissent entendre que l'anxiété devant l'examen et la révision de la matière dans les mois suivant l'obtention du diplôme semblent avoir un effet sur le rendement à l'examen. Aussi, certaines caractéristiques démographiques comme l'âge et les difficultés financières semblaient être indicatifs du succès futur.

La posición socio económica en el campo de la actividad física y su relación con la imagen corporal: Aproximación desde el enfoque determinantes/ determinación social de la salud

El presente trabajo analiza la definición de la categoría posición socioeconómica (PSE) y las variables con las cuales se representa en los productos académicos del campo de la actividad física, además de su relación con la categoría de imagen corporal. Para lograr el objetivo, se rastrean elementos que permiten dar cuenta si los documentos de investigación se abordan desde alguno de los dos contextos: determinantes (DDSS) o determinación social de la salud (DSS). Se inicia con un rastreo global por medio de los motores de búsqueda, las bases de datos y los repositorios institucionales. Posteriormente se parametriza la ruta, desde las categorías imagen corporal (IC) y PSE. Las investigaciones pretenden dar cuenta de la evaluación a 15 años del programa "Salud para Todos" de la ONU de 2001, en el marco de los Objetivos Del Milenio. Se revisaron resúmenes de los productos, descartando aquellos donde la categoría PSE o sus descriptores asociados tuvieran un papel secundario. Se limitó a Latinoamérica y España por su tradición histórica colonizadora; con el ánimo de conocer la postura de esta comunidad frente al proceso globalizado de la salud en el mundo. Al grupo final se le aplican criterios parametrizados a partir de la revisión teórica, para responder los interrogantes basados en las implicaciones que tiene la PSE en el pensamiento actual de la producción científica en el campo de la actividad física; y cómo las otras categorías de análisis se ven o no manifiestas. El índice de calidad científica CASPe, determina la pertinencia de los textos. En el aspecto teórico, se encuentra que la categoría PSE, a pesar de ser muy utilizada, tiene una conceptualización difusa. Por tal motivo, se propone una definición de PSE sustentada en el pensamiento sociológico. En el aspecto empírico, al rastrear las variables con que se reemplaza la PSE en las investigaciones, se encuentran grandes diferencias y el uso de múltiples y disímiles subcategorías.
