Diferencias demográficas y socioeconómicas asociadas al consumo de bebidas azucaradas en niños y adolescentes Colombianos

Introduction: sugar-sweetened beverages (SSB) are becoming a common component in the diets among children and adolescents, and its consumption is associated with an increased risk factors for cardiovascular disease. The aim of the present study was to describe the consumption of sugar-sweetened beverages among Colombian children and adolescents and to examine whether differences by demographic and socioeconomic according to gender. Methods: we used data from the 2010 National Nutrition Survey of Colombia (ENSIN 2010) for 10 373 children and adolescents between 5 and 17 years old. SSB intake was based on intake from regular soda and/ or concentrated drinks. Demographic factors (sex, age, ethnicity, urbanicity, area and geographic region) and socioeconomic level (social class) were collected by structured questionnaire. Associations were established through a multivariate logistic regression. All analyzes were calculated by complex samples. Results: nationwide, 23% of girls and 22.4% of boys drank SSB at least once a week. Differences by demographic factors were observed for SSB consumption. In girls, factors associated with a greater odds for SSB intake (? 1 time/week) were aged 14 to 17 years old [OR = 1.65 (95%CI = 1.32, 2.06)], living in the central region [OR = 2.42 (95%CI = 1.81, 3.25)] and urban area [OR = 1.77 (95%CI = 1.42, 2.20)]. In boys, the multivariate logistic regression shows that adolescents aged 14 to 17 years old [OR = 1.96 (95%CI = 1.58, 2.24)], living in the national territories (South) [OR = 2.42 (95%CI = 1.77, 3.32)] and urban area [OR = 1.79 (95%CI = 1.45, 2.20)] were associated with a higher probability of SSB consumption. Social class was not associated with SSB intake. Conclusions: SSB intake varies by certain demographic factors. Government can use findings from this study to tailor efforts to decrease SSB intake and to encourage consumption of more healthful beverages (e.g, water) among Colombian children and adolescents Conclusions: SSB intake varies by certain demographic factors. Government can use findings from this study to tailor efforts to decrease SSB intake and to encourage consumption of more healthful beverages (e.g, water) among Colombian children and adolescents © 2015, Grupo Aula Medica S.A.

Niveles de ferritina en mujeres gestantes de Colombia

Objective: Ferritin deficiency is associated with many adverse health outcomes and is highly prevalent worldwide. The present study assesses the prevalence and socio-demographic factors associated with ferritin deficiency in a representative sample of pregnant women in Colombia. Methods: We used data from the cross-sectional, nationally representative survey National Nutritional Survey (ENSIN, 2010). A total of 1,386, (13-49 years old) pregnant women were enrolled. Serum ferritin a concentration was determined by chemiluminescence and sociodemographic date (age, urbanicity geographic region, ethnicity and socioeconomic level-SISBEN), was assessed by computer-assisted personal interview technology. Multivariate analyses using unordered binomial logistic regression models were conducted in the main analysis. Results: The overall prevalence of ferritin deficiency (serum less than 12µg/L) was 37.2% (95% CI 35.0% to 39.2%). The multivariate logistic regression no shows associated with a probability of serum ferritin deficiencies. Conclusion: A significant prevalence of ferritin deficiency was found in our study population without an association with the studied sociodemographic factors. © 2015, Grupo Aula Medica S.A.

Using LMS tables to determine waist circumference and waist-to-height ratios in Colombian children and adolescents : The FUPRECOL study

Background: Waist circumference (WC) and waist-to-height ratio (WHtR) are often used as indices predictive of central obesity. The aims of this study were: 1) to obtain smoothed centile charts and LMS tables for WC and WHtR among Colombian children and adolescents; 2) to evaluate the utility of these parameters as predictors of overweight and obesity. Method: A cross-sectional study was conducted of a sample population of 7954 healthy Colombian schoolchildren [3460 boys and 4494 girls, mean age 12.8 (±2.3) years]. Weight, height, body mass index (BMI), WC and WHtR were measured, and percentiles were calculated using the LMS method (Box-Cox, median and coefficient of variation). Appropriate cut-off points of WC and WHtR for overweight and obesity, according to International Obesity Task Force definitions, were selected using receiver operating characteristic (ROC) analysis. The discriminating power of WC and WHtR is expressed as area under the curve (AUC). Results: Reference values for WC and WHtR are presented. Mean WC increased and WHtR decreased with age for both genders. A moderate positive correlation was observed between WC and BMI (r = 0.756, P < 0.01) and between WHtR and BMI (r = 0.604, P < 0.01). ROC analysis revealed strong discrimination power in the identification of overweight and obesity for both measures in our sample population. Overall, WHtR was a slightly better predictor of overweight/obesity (AUC 95% CI 0.868-0.916) than WC (AUC 95% CI 0.862-0.904). Conclusion: This paper presents the first sex and age-specific WC and WHtR percentiles for Colombian children and adolescents aged 9.0-17.9 years. The LMS tables obtained, based on Colombian reference data, can be used as quantitative tools for the study of obesity and its comorbidities. © 2017 The Author(s)

Conocimientos sobre métodos anticonceptivos de emergencia en estudiantes universitarios: revisión sistemática

El artículo se basó en una revisión sistemática de la literatura sobre el conocimiento y la percepción de los métodos anticonceptivos de emergencia (AE) entre los estudiantes universitarios. Se examinaron 66 artículos y se seleccionaron 17 para su revisión. Se encontró que existe una falta de conocimiento adecuado sobre los AE, con diferentes estudios informando niveles deficientes de conocimiento en los participantes. Además, se observaron barreras significativas para el acceso y el uso de los AE, como el miedo a los efectos secundarios, factores religiosos y culturales, y dificultades de acceso. Las principales fuentes de información sobre los AE fueron Internet, amigos y medios de comunicación. Se destacó la importancia de mejorar la difusión de información sobre los AE utilizando plataformas digitales como Instagram y TikTok. Se identificaron mitos y malentendidos sobre los AE, como la creencia de que son abortivos. También, se señaló la necesidad de brindar información clara sobre los efectos secundarios y adversos de los AE, para que las personas estén mejor informadas al usarlos. En general, se concluyó que es necesario mejorar el conocimiento, la percepción y el acceso a los métodos AE en la población estudiantil universitaria. Sin embargo, se señaló la falta de uniformidad en los formularios utilizados en los estudios revisados, lo que dificulta la comparación y el análisis de los resultados. Se sugiere el desarrollo de normas para el diseño y la validación de formularios en futuras investigaciones. Palabras clave: Anticonceptivos, anticonceptivo de emergencia, conocimientos, estudiantes universitarios.   ABSTRACT The study was based on a systematic review of the literature on knowledge and perception of emergency contraception (EC) among college students. 66 articles were examined and 17 were selected for review. It was found that there is a lack of adequate knowledge about AEs, with different studies reporting poor levels of knowledge in the participants. In addition, significant barriers to accessing and using ECs were observed, such as fear of side effects, religious and cultural factors, and access difficulties. The main sources of information about EA were the Internet, friends, and the media. The importance of improving the dissemination of information on AEs using digital platforms, such as Instagram and TikTok, was highlighted. Myths and misunderstandings about ECs were identified, such as the belief that they are abortifacient. The need to provide clear information on the side and adverse effects of ECs was also noted, so that people are better informed when using them. In general, it was concluded that it is necessary to improve the knowledge, perception and access to emergency contraceptive methods in the university student population. It is recommended to promote sexual and reproductive education programs, address cultural and religious myths and barriers, and use digital platforms to effectively disseminate information about EC. However, the lack of uniformity in the forms used in the reviewed studies was noted, making it difficult to compare and analyze the results. The development of standards for the design and validation of forms is suggested in future research. Keywords: Contraceptives, emergency contraception, knowledge, university students

Body Adiposity Index Performance in Estimating Body Fat Percentage in Colombian College Students : Findings from the FUPRECOL-Adults Study

Abstract: Recently, a body adiposity index (BAI = (hip circumference)/((height)(1.5))−18) was developed and validated in adult populations. The aim of this study was to evaluate the performance of BAI in estimating percentage body fat (BF%) in a sample of Colombian collegiate young adults. The participants were comprised of 903 volunteers (52% females, mean age = 21.4 years ± 3.3). We used the Lin’s concordance correlation coefficient, linear regression, Bland–Altman’s agreement analysis, concordance correlation coefficient (ρc) and the coefficient of determination (R 2 ) between BAI, and BF%; by bioelectrical impedance analysis (BIA)). The correlation between the two methods of estimating BF% was R 2 = 0.384, p < 0.001. A paired-sample t-test showed a difference between the methods (BIA BF% = 16.2 ± 3.1, BAI BF% = 30.0 ± 5.4%; p < 0.001). For BIA, bias value was 6.0 ± 6.2 BF% (95% confidence interval (CI) = −6.0 to 18.2), indicating that the BAI method overestimated BF% relative to the reference method. Lin’s concordance correlation coefficient was poor (ρc = 0.014, 95% CI = −0.124 to 0.135; p = 0.414). In Colombian college students, there was poor agreement between BAI- and BIA-based estimates of BF%, and so BAI is not accurate in people with low or high body fat percentage levels
