Molecular, biochemical, and sensorial characterization of cocoa (Theobroma cacao L.) beans: A methodological pathway for the identification of new regional materials with outstanding profiles.

Cocoa is an economically important product in Colombia. On-farm germplasm evaluations enable the selection of superior genotypes for propagation and distribution across the country. This study examined 12 cocoa samples from Antioquia along with five reference materials, employing 96 single nucleotide polymorphism (SNP) markers. Furthermore, these genetic findings were correlated with physical, chemical, and sensory attributes. Primary coordinate analysis revealed that the majority of samples were hybrids derived from five original germplasm pools, including Criollo, Amelonado, and three Upper Amazon Forastero cocoas. The integral profile of the 12 selected materials was classified into Modern Criollo (Rodriguez-Medina et al., 2019) [3], Forasteros (Rodriguez-Medina et al., 2019) [3], and Trinitarios (Borja Fajardo et al., 2022) [6]. Three key factors were identified to best account for the sample classification: type of variety, functional properties, and quality.

Feasibility Study: Colombian Caribbean Folk Dances to Increase Physical Fitness and Health-Related Quality of Life in Older Women.

The objectives of the study were to describe the feasibility of an intervention in older women based on folk dances of the Colombian Caribbean region, and to analyze the effects of the intervention on physical fitness and health-related quality of life (HRQoL). A pilot study was conducted in a sample of 27 participants, 15 in the intervention group (IG) and 12 in the comparison group (CG). Caribbean Colombian dance rhythms were introduced as an intervention that lasted 12 weeks. Recruitment and retention was not optimal. Treatment fidelity components indicated that intervention was administered as intended. IG participants showed positive and statistically significant changes in some components of physical fitness. No significant changes were observed in HRQoL indicators for either group. In conclusion, the intervention was feasible, but recruitment and retention was challenging. Folk dances of the Colombian Caribbean region provoked significant results in physical fitness but not in HRQoL.

Associations between time spent traveling in motor vehicles and physical activity in Colombian adults from urban areas.

Sedentary behaviors are associated with less physical activity. Little evidence exists about this association and its relation with commuting time in Latin America. This study examined the association between time spent traveling in motor vehicles and physical activity levels in the domains of leisure time physical activity and transportation, among Colombian adults in urban areas. A secondary data analysis of the 2010 National Nutrition Survey was conducted. Time spent traveling in motor vehicles and physical activity were assessed using the International Physical Activity Questionnaire. Binary logistic regressions were conducted. Time spent traveling in motor vehicles for 120 minutes or more was reported among 27.6% of the sample. The prevalence of walking and bicycling as a means of transportation for at least 150 minutes per week was 34% and 4.4%, respectively. Achieving at least 150 minutes of leisure time physical activity a week was reported by 18.4% of the sample. This study suggests negative associations between time spent traveling in motor vehicles and active transport, with significant trend associations in stratified analyses. No significant associations were found between time spent traveling in motor vehicles and leisure time physical activity.

Conglomeración de precursores de tensión arterial elevada en adolescentes / Conglomeration of high blood pressure precursors in adolescents

Introducción: La tensión arterial elevada y los precursores de enfermedad cardiovascular, pueden iniciarse en la infancia y mantenerse hasta la adultez. Estos precursores ocurren frecuentemente en conglomerado. Objetivos: Analizar la conglomeración de precursores de tensión arterial alta en adolescentes y determinar la asociación de la frecuencia acumulada de estos con la tensión arterial elevada. Métodos: Estudio transversal en una muestra de 546 escolares de 11 a 18 años de la ciudad de Montería. Se tomaron medidas de tensión arterial, índice de masa corporal, perímetro abdominal, capacidad cardiorrespiratoria, niveles de actividad física y comportamientos sedentarios. Las asociaciones entre tensión arterial elevada y frecuencia acumulada de precursores fueron exploradas con modelos de regresión logística. Resultados: La combinación de precursores más frecuente fue la presencia de dos precursores, inactividad física y tiempo excesivo de televisión (30,3%). Le siguen la aparición simultánea de tres precursores, baja capacidad cardiorrespiratoria, inactividad física y tiempo excesivo de televisión (18,3%). Aquellos adolescentes con dos o más precursores presentaron cifras de tensión arterial significativamente más altas en comparación con aquellos en quienes se encontró una acumulación menor de precursores. La tensión arterial elevada se asocia de manera significativa con la acumulación de precursores. Conclusión: La conglomeración de dos o más precursores se asoció de manera significativa con la tensión arterial elevada, hallazgos que indican que se requieren intervenciones para reducir la presencia y acumulación de los precursores estudiados y así prevenir la adquisición de cifras de tensión arterial elevada en los adolescentes de Montería.

Introduction: High blood pressure and cardiovascular disease precursors may start in childhood and continue until adulthood. Usually these precursors occur in cluster. Objectives: The objectives of the study were to analyze the cluster of high blood pressure precursors and to analyze the association of the cumulative frequency of these precursors with high blood pressure. Methods: Cross-sectional study in a sample of 546 students aged 11 to 18 years in the city of Montería. Blood pressure, body mass index, waist circumference, cardiorespiratory fitness, physical activity and sedentary lifestyle were measured. The associations between high blood pressure and the cumulative frequency of precursors were explored with logistic regression models. Results: The most frequently found combination of precursors was the presence of two precursors, physical inactivity and excessive TV time (30.3%). It follows the simultaneous occurrence of three precursors: low cardiorespiratory fitness, physical inactivity, and excessive TV time (18.3%). Those adolescents with two or more precursors showed a significantly higher occurrence of high blood pressure compared to those in whom a lower accumulation of precursors was found. The occurrence of high blood pressure is significantly associated with the accumulation of precursors. Conclusion: The conglomeration of two or more precursors was significantly associated with the occurrence of high blood pressure. These findings indicate that interventions are needed to reduce the occurrence and accumulation of precursors studied, as well as to prevent the acquisition of high blood pressure in adolescents of Montería.

Screen time, cardiorespiratory fitness and adiposity among school-age children from Monteria, Colombia.

OBJECTIVES: To explore the association between electronic media exposure (television viewing time, personal computer/video game use, total screen time), and waist circumference and body mass index, and study whether this association is independent of cardiorespiratory fitness, in a representative sample of adolescents from Montería, Colombia. DESIGN: Cross-sectional study analyzing data from 546 students aged 11-18 years, from fourteen randomly selected schools. Z-scores for WC and BMI were calculated. METHODS: The physical activity module of the Global School Health Survey 2007 was used to determine EME, and the shuttle run test was used to assess CRF. Linear regression models adjusted by age, school location, physical activity level, type of institution (public or private), consumption of sweetened beverages, fast food, and fried food were used. RESULTS: Among boys, independently of cardiorespiratory fitness, high television viewing time (≥ 2 h/day) (ß=+0.22; p<0.02), was positively associated with waist circumference. High total screen time (>3h/day) was positively associated with waist circumference (ß=+0.34; p<0.01), and body mass index (ß=+0.39; p<0.01). Among girls, sedentary behavior was not associated with adiposity, but cardiorespiratory fitness (ß=-0.04; p<0.02) was negatively associated with body mass index. CONCLUSIONS: These findings support the evidence on the negative impact of excessive electronic media exposure and low cardiorespiratory fitness, and highlight the need for interventions and prevention strategies.

Association between the perceived environment and physical activity among adults in Latin America: a systematic review.

BACKGROUND: Activity friendly environments have been identified as promising strategies to increase physical activity levels in the population. Associations between perceived environmental attributes and physical activity in Latin America may vary from those observed in high income countries. The objective of this systematic review is to identify which perceived environmental attributes are associated with physical activity in Latin America. METHODS: Systematic literature search of articles published in English, Portuguese, and Spanish in four databases was conducted (PubMed, Virtual Health Library, EBSCO, and Web of Science). Associations with environmental attributes were analyzed separately for physical activity domains. Fifteen articles were included in the analysis. RESULTS: All studies had cross-sectional designs. The majority of associations were statistically non-significant, and only four associations were found in the unexpected direction. Leisure-time and transport-related physical activity were the domains most frequently included in the studies and had higher number of associations in the expected direction. Leisure-time physical activity showed a convincing association in the expected direction with safety during the day. Transport-related physical activity had a convincing association with presence of street lighting. CONCLUSIONS: This study shows that perceived environmental attributes and their relationship with physical activity appears to be domain, and context specific. In addition, findings from this study show inconsistencies with the information gathered from high-income countries.

Should they play outside? Cardiorespiratory fitness and air pollution among schoolchildren in Bogotá / ¿Deberían los niños jugar al aire libre? Acondicionamiento cardiorespiratorio y contaminación del aire en Bogotá

Objective: This study was aimed at comparing cardiorespiratory fitness (CF), measured as VO2 max, amongst school children exposed to varying levels of particulate matter (PM10), and air pollution in Bogotá, Colombia. Methods: This was a cross-sectional study; it involved 1,045 children aged 7-12 attending four public schools served by different public transit routes and systems. Three schools were classified as being highly polluted (HP) and one slightly polluted (SP). The children and their parents were surveyed to collect data regarding their socio-demographic characteristics, physical activity habits and respiratory disease background. Objective measurements of weight and height were used to calculate the body mass index. VO2max was estimated using the 20-meter shuttle-run test, previously validated for Bogotá. Spirometry was performed on 435 children. Results: After adjustment for covariates, no difference was found in VO2max between children attending SP or HP schools (girls SP 45.8 ml/kg/min vs HP 44.6 ml/kg/min, p=0.11; boys SP 47.2 ml/kg/min cf HP 48.2 ml/kg/min, p=0.41). Conclusions: VO2max levels did not differ amongst children attending schools exposed to high compared to low levels of air pollution and PM. A longitudinal study assessing children’s VO2max levels in relation to exposure to highly-polluted areas is warranted.

Objetivo: Comparar el acondicionamiento cardiorespiratorio medido como VO2 máximo en niños escolarizados expuestos a diferentes niveles de PM10 en Bogotá. Métodos: Estudio de corte transversal. Se incluyeron 1045 niños de 7-12 años de 4 colegios públicos con diferentes corredores viales y sistemas de transporte público. Tres colegios tenían alta contaminación (AC) y uno baja contaminación (BC). Se aplicó una encuesta a niños y padres sobre características sociodemográficas, actividad física, antecedentes de enfermedades respiratorias y salud. Se midió objetivamente peso y talla para calcular el índice masa corporal. El VO2 máximo se estimó con la prueba de Leger validada para Bogotá. Se realizaron espirometrias en 435 niños. Resultados: Después de ajustar por covariables, no se encontraron diferencias significativas en el VO2 máximo de los niños en colegios con BC ò AC. (Niñas BC: 45,8ml/kg/min vs. AC: 44,6ml/kg/min; p=0,11, niños BC: 47,2ml/kg/min vs. AC: 48,2ml/kg/min; p=0,41). Conclusión: No se encontraron diferencias en el VO2 máximo de los niños que asistían a los colegios de AC ó BC. Se recomienda un estudio longitudinal que evalúe los niveles de VO2 máximo en los niños expuestos a áreas altamente contaminadas.
