RESUMEN

Human astrovirus is an important cause of viral gastroenteritis worldwide. Young children, the elderly, and the immunocompromised are especially at risk for contracting severe disease. However, no vaccines exist to combat human astrovirus infection. Evidence points to the importance of antibodies in protecting healthy adults from reinfection. To develop an effective subunit vaccine that broadly protects against diverse astrovirus serotypes, we must understand how neutralizing antibodies target the capsid surface at the molecular level. Here, we report the structures of the human astrovirus capsid spike domain bound to two neutralizing monoclonal antibodies. These antibodies bind two distinct conformational epitopes on the spike surface. We add to existing evidence that the human astrovirus capsid spike contains a receptor-binding domain and demonstrate that both antibodies neutralize human astrovirus by blocking virus attachment to host cells. We identify patches of conserved amino acids which overlap or border the antibody epitopes and may constitute a receptor-binding site. Our findings provide a basis for developing therapies to prevent and treat human astrovirus gastroenteritis. IMPORTANCE Human astroviruses infect nearly every person in the world during childhood and cause diarrhea, vomiting, and fever. Despite the prevalence of this virus, little is known about how antibodies block astrovirus infection. Here, we determined the crystal structures of the astrovirus capsid protein in complex with two virus-neutralizing antibodies. We show that the antibodies bind to two distinct sites on the capsid spike domain, however, both antibodies block virus attachment to human cells. Importantly, our findings support the use of the human astrovirus capsid spike as an antigen in a subunit-based vaccine to prevent astrovirus disease.

RESUMEN

OBJECTIVE: This study sought to evaluate the effect of eugenol on the cell morphology and expression of genes involved in the apoptotic process in human dental pulp fibroblasts (hDPFs) from deciduous teeth. MATERIALS AND METHODS: hDPFs were cultured with 4 concentrations of eugenol (0.06 nM, 0.6 nM, 6 nM, 12 nM) and compared with a control group. After a 72 h incubation period, the cytotoxic effect on cell morphology by optical microscopy and gene expression by RT-PCR were evaluated. RESULTS: At 0.06 nM and 0.6 nM eugenol concentrations, vacuolisation of the cytoplasm was observed with atypical granulation of the hDPFs, and, at 6 nM and 12 nM cytoplasmic extensions disappeared almost completely. Casp-3, Casp-9, and telomerase genes were not expressed at the concentrations evaluated nor in the control group. The relative expression responses of Bcl-2 and TGF-ß genes were overexpressed at the 4 concentrations. MAKP's 0.06 nM (p < .001), 0.6 nM (p < .05) and 12 nM (p < .05) and Cyclin 1 at 12 nM showed significant difference versus the control group (p < .05). CONCLUSION: Eugenol is capable of causing morphological changes in hDPFs in a dose-dependent manner, higher concentrations may promote overexpression of apoptotic genes.

RESUMEN

BACKGROUND: Low back pain (LBP) is a condition with a high global prevalence, which is getting health professionals' attention, including physiotherapists as they must have the skills to provide treatment that increases the patient's quality of life. Clinical simulations could be a pedagogic strategy that facilitates adequate training for students to acquire skills to improve their professional reasoning in this clinical situation. OBJECTIVE: This study sought to determine the effects of clinical simulations with simulated patients (SP) on the physiotherapy students' clinical decision-making within a role-playing (RP) scenario while caring of LBP patients. METHODS: This experimental study included 42 participants from two Colombian universities, randomized into two groups (SP, n = 21; RP, n = 21). The clinical skill of performing the Objective Structured Clinical Examination (OSCE-LBP) was evaluated while students cared for patients with LBP; after that, a pedagogical method was conducted that included clinical simulation and, finally, the OSCE-LBP was applied again to compare both groups. RESULTS: Changes occurred in the OSCE-LBP among both groups of students: the scores increased (0.66 and 0.59 in RP and SP, respectively), and neither of the two was superior (p value 0.01; 95%CI - 0.21 to 0.23). CONCLUSION: Both types of simulation favor decision-making in professional reasoning in physiotherapy students during interactions with individuals with LBP. Trial registration https://clinicaltrials.gov/ct2/show/NCT04428892 Identifying number: NCT04428892. It was retrospectively registered.

RESUMEN

Garcia-Hermoso, A, Correa-Bautista, JE, Izquierdo, M, Tordecilla-Sanders, A, Prieto-Benavides, D, Sandoval-Cuellar, C, González-Ruíz, K, and Ramírez-Vélez, R. Ideal cardiovascular health, handgrip strength, and muscle mass among college students: the FUPRECOL Adults study. J Strength Cond Res 33(3): 747-754, 2019-The American Heart Association established the 2020 Strategic Impact Goals to define the concept of ideal cardiovascular health (CVH) and the metrics needed to monitor it across populations. The purpose of this study was to investigate the relationship between handgrip strength, muscle mass, and ideal CVH among Colombian college students. Data from 1,835 college students were analyzed (1,128 female). Muscular strength was estimated using a hand-held dynamometer and normalized to body mass (normalized grip strength [NGS]). The percentage of body fat was determined for bioelectrical impedance analysis using tetrapolar whole-body impedance. Ideal CVH was defined as meeting the ideal levels of 4 behaviors (smoking, body mass index, physical activity, and diet adherence) and 3 factors (total cholesterol, fasting glucose, and blood pressure). Higher levels of NGS and muscle mass (relative to body mass) were associated with a higher number of ideal CVH metrics in both sexes (p for trend <0.001). For the total ideal CVH metrics scored on a continuous scale from 0 (all 7 poor) to 7 (all 7 ideal), a 1-metric increase was associated with reduced odds of weak NGS (33 and 36%) and low-medium muscle mass (28 and 34%) mass in men and women, respectively (all p < 0.001). This study indicates that in Colombian college students, both handgrip strength and muscle mass are positively associated with the ideal CVH metrics. To reduce the possible future public health burden of muscular weakness, health professionals need to encourage the public to optimize lifestyle-related risk factors during the young adult stage.

RESUMEN

BACKGROUND: There is limited evidence concerning how active commuting (AC) is associated with health benefits in young. The aim of the study was to analyze the relationship between AC to and from campus (walking) and obesity and metabolic syndrome (MetS) in a sample of Colombian university students. METHODS: A total of 784 university students (78.6% women, mean age = 20.1 ± 2.6 years old) participated in the study. The exposure variable was categorized into AC (active walker to campus) and non-AC (non/infrequent active walker to campus: car, motorcycle, or bus) to and from the university on a typical day. MetS was defined in accordance with the updated harmonized criteria of the International Diabetes Federation criteria. RESULTS: The overall prevalence of MetS was 8.7%, and it was higher in non-AC than AC to campus. The percentage of AC was 65.3%. The commuting distances in this AC from/to university were 83.1%, 13.4% and 3.5% for < 2 km, 2-5 km and > 5 km, respectively. Multiple logistic regressions for predicting unhealthy profile showed that male walking commuters had a lower probability of having obesity [OR = 0.45 (CI 95% 0.25-0.93)], high blood pressure [OR = 0.26 (CI 95% 0.13-0.55)] and low HDL cholesterol [OR = 0.29 (CI 95% 0.14-0.59)] than did passive commuters. CONCLUSIONS: Our results suggest that in young adulthood, a key life-stage for the development of obesity and MetS, AC could be associated with and increasing of daily physical activity levels, thereby promoting better cardiometabolic health.

RESUMEN

An assortment of clinical and laboratory abnormalities may occur as paraneoplastic syndromes in lymphomas. Rheumatological and dermatological manifestations such as paraneoplastic arthritis and pyoderma gangrenosum must be underscored. We report a 28 years old woman who developed pyoderma gangrenosum and two years later presented with arthritis of knees and ankles associated with panniculitis interpreted as erythema induratum that was pathologically confirmed. She developed a reactivation of pyoderma gangrenosum, that was refractory to treatment. Complementary studies showed a pulmonary nodule and a right paravertebral mass with involvement of the psoas muscle. Biopsies of both masses and a new pathological skin study demonstrated a large B-cell non-Hodgkin's lymphoma.

RESUMEN

IgG4 disease is a multi-systemic condition involving pancreas, salivary glands and lymph nodes. Less frequently, it causes interstitial nephritis and involves the lungs. We report a 58 years old male with a four years history of hemoptysis and renal dysfunction characterized by hematuria and proteinuria, responsive to steroidal therapy. The renal biopsy established the diagnosis of IgG4 associated interstitial nephritis. Lung involvement was considered secondary to the same systemic disease.

RESUMEN

To ensure safe, optimal, and personalized physical activity, exercise, or sport during pregnancy, the Canadian Society for Exercise Physiology (CSEP), the Society of Obstetricians and Gynaecologists of Canada (SOGC), the College of Family Physicians of Canada, the Women's Health Division of the Canadian Physiotherapy Association, developed the Get Active Questionnaire for Pregnancy (GAQ_P) as a pre-assessment to identify women who may have a relative or absolute contraindication to prenatal exercise that requires further consultation with a health professional to determine if exercise can or should be continued or initiated during pregnancy. This study aims to translate and cross-culturally adapt the GAQ_P for use in Colombian Spanish. The original instrument was developed in English and French for the evaluation of the health of pregnant women before the beginning of physical activity and the guidelines for the same. Ten steps were followed according to the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Translation and Cultural Adaptation guidelines, with the participation of 4 experts. The comprehensibility of the instrument was 99% which shows a high percentage of intelligibility of the document. This article describes the translation and cross-cultural adaptation of the GAQ_P for use in Colombian Spanish, contributing positively to pre-exercise screening during pregnancy in Colombia.

RESUMEN

The accurate monitoring of metabolic syndrome in older adults is relevant in terms of its early detection, and its management. This study aimed at proposing a novel semiparametric modeling for a cardiometabolic risk index (CMRI) and individual risk factors in older adults. METHODS: Multivariate semiparametric regression models were used to study the association between the CMRI with the individual risk factors, which was achieved using secondary analysis the data from the SABE study (Survey on Health, Well-Being, and Aging in Colombia, 2015). RESULTS: The risk factors were selected through a stepwise procedure. The covariates included showed evidence of non-linear relationships with the CMRI, revealing non-linear interactions between: BMI and age (p< 0.00); arm and calf circumferences (p<0.00); age and females (p<0.00); walking speed and joint pain (p<0.02); and arm circumference and joint pain (p<0.00). CONCLUSIONS: Semiparametric modeling explained 24.5% of the observed deviance, which was higher than the 18.2% explained by the linear model.

RESUMEN

BACKGROUND: Deviations occur in the neuropsychomotor development of premature infants; early interventions minimize delay motor. This study aimed to determine the effect of an interdisciplinary hospital-home intervention addressing motor development adaptation in premature infants in Colombia in comparison with traditional interventions. METHODS: This study was based on a parallel design, with two groups, namely, experimental and control. The experimental group, hospital-home intervention (HHI) performed in two settings (i.e., hospital neonatal care units and homes), and the control group, traditional intervention, (TI) performed in institutions for premature infants. The sample will be composed of 130 randomly-allocated infants, 65 in the experimental group (HHI) and 65 in the control group (TI) of moderate to late preterm infants (gestational age between 34 and 37 weeks), weighing more than or equal to 1.800 g, who are hemodynamically stable and reside in the cities of Tunja and Bogotá-Colombia recruited between 2021 and 2022. For the pre- and post-intervention assessments, the TIMPSI and the CapDMP are the instruments used to assess motor development and the degree of parents' or caregivers' knowledge about motor development. The HHI is composed of 10 intervention strategies based on stimulation of motor development, performed twice a day for 10 min for two months, in combination with calls to a mobile device, using software (Baby Motor Skills) and an instant messaging system (WhatsApp). RESULTS: This hospital-home intervention program proposes an approach focused on the motor development of premature infants, based on sensory and motor stimulation strategies, in addition to follow-up performed at home with the use of a mobile application that improves the motor development of premature infants. Register Clinical Trial: NCT04563364. CONCLUSION: The HHI provides the opportunity to determine whether the individualized four-week from admission to follow up at home with parent training will improve the motor skills of premature infants.

RESUMEN

OBJECTIVE: To determine the diagnostic validity of the enzyme-linked immunosorbent assay (ELISA) and Rapid Diagnostic Tests (RDT) among individuals with suspected chronic Chagas Disease (CD). METHODOLOGY: A search was made for studies with ELISA and RDT assays validity estimates as eligibility criteria, published between 2010 and 2020 on PubMed, Web of Science, Scopus, and LILACS. This way, we extracted the data and assessed the risk of bias and applicability of the studies using the QUADAS-2 tool. The bivariate random effects model was also used to estimate the overall sensitivity and specificity through forest-plots, ROC space, and we visually assessed the heterogeneity between studies. Meta-regressions were made using subgroup analysis. We used Deeks' test to assess the risk of publication bias. RESULTS: 43 studies were included; 27 assessed ELISA tests; 14 assessed RDTs; and 2 assessed ELISA and RDTs, against different reference standards. 51.2 % of them used a non-comparative observational design, and 46.5 % a comparative clinical design ("case-control" type). High risk of bias was detected for patient screening and reference standard. The ELISA tests had a sensitivity of 99% (95% CI: 98-99) and a specificity of 98% (95% CI: 97-99); whereas the Rapid Diagnostic Tests (RDT) had values of 95% (95% CI: 94-97) and 97% (95% CI: 96-98), respectively. Deeks' test showed asymmetry on the ELISA assays. CONCLUSIONS: ELISA and RDT tests have high validity for diagnosing chronic Chagas disease. The analysis of these two types of evidence in this systematic review and meta-analysis constitutes an input for their use. The limitations included the difficulty in extracting data due to the lack of information in the articles, and the comparative clinical-type design of some studies.

RESUMEN

Excess central adiposity accelerates the decline of muscle strength in older people. Additionally, hyperglycemia, independent of associated comorbidities, is related to the loss of muscle mass and strength, and contributes to functional impairment in older adults. We studied the mediation effect of glucose levels, in the relationship between abdominal obesity and relative handgrip strength (HGS). A total of 1571 participants (60.0% women, mean age 69.1 ± 7.0 years) from 86 municipalities were selected following a multistage area probability sampling design. Measurements included demographic and anthropometric/adiposity markers (weight, height, body mass index, and waist circumference). HGS was measured using a digital dynamometer for three sets and the mean value was recorded. The values were normalized to body weight (relative HGS). Fasting glucose was analyzed by enzymatic colorimetric methods. Mediation analyses were performed to identify associations between the independent variable (abdominal obesity) and outcomes (relative HGS), as well as to determine whether fasting glucose levels mediated the relationship between excess adiposity and relative HGS. A total of 1239 (78.8%) had abdominal obesity. Abdominal obesity had a negative effect on fasting glucose (ß = 9.04, 95%CI = 5.87 to 12.21); while fasting glucose to relative HGS was inversely related (ß = -0.003, 95%CI = -0.005 to -0.001), p < 0.001. The direct effect of abdominal obesity on relative HGS was statistically significant (ß = -0.069, 95%CI = -0.082 to -0.057), p < 0.001. Lastly, fasting glucose levels mediates the detrimental effect of abdominal obesity on relative HGS (indirect effect ß = -0.002, 95%CI = -0.004 to -0.001), p < 0.001. Our results suggest that the glucose level could worsen the association between abdominal obesity status and lower HGS. Thus, it is plausible to consider fasting glucose levels when assessing older adults with excess adiposity and/or suspected loss of muscle mass.

RESUMEN

BACKGROUND: Evidence shows an association between grip strength and health; however, grip strength cut-offs for the detection of metabolic syndrome (MetS) in Latin American populations are scarce. The purpose of this study was to determine cut-offs of normalized grip strength (NGS) for the detection of MetS in a large nonrepresentative sample of a collegiate student population from Colombia. METHODS: A total of 1795 volunteers (61.4% female; age = 20.68 ± 3.10 years, mean ± SD), ranging between 18 and 30 years of age participated in the study. Strength was estimated using a handheld dynamometer and normalized to body mass (handgrip strength (kg)/body mass (kg)). Anthropometrics, serum lipids indices, blood pressure, and fasting plasma glucose were measured. Body composition was measured by bioelectrical impedance analysis. MetS was defined as including ≥3 of the 5 metabolic abnormalities according to the International Diabetes Federation definition. A metabolic risk score was computed from the following components: waist circumference, triglycerides, high-density lipoprotein cholesterol, glucose, and systolic and diastolic blood pressure. RESULTS: Receiver operating curve analysis showed significant discriminatory accuracy of NGS in identifying the thresholds and risk categories. Lower strength was associated with increased prevalence of MetS. In males, weak, intermediate, and strong NGS values at these points were <0.466, 0.466-0.615, >0.615, respectively. In females, these cut-off points were <0.332, 0.332-0.437, >0.437, respectively. CONCLUSION: Our sex-specific cut-offs of NGS could be incorporated into a clinical setting for identifying college students at cardiometabolic disease risk.

RESUMEN

BACKGROUND: The diagnosis of CLL is supported by a typical morphology and immunophenotype and usually does not present difficulties. Nevertheless, some patients with CLL can show an atypical phenotype, this raising the possibility of a lymphoproliferative disorder other than CLL. It has been recently shown that the expression of CD200 could be a rather consistent marker for CLL. METHODS: The expression of CD200 was investigated in 120 consecutive patients with B-cell chronic lymphoproliferative disorders (B-CLPD) (65 cases diagnosed as typical CLL, 16 atypical CLL, and 39 non-CLL before entering the study) by using multiparametric flow cytometry with four color combinations. CD200 was analyzed as percentage of positive cells (≥30%) and MFIR expression. ROC curves were used to determine the cut-off for the CD200 MFIR. Matutes score (MS) was used as comparator. RESULTS: All 81 (100%) patients classified as CLL and 25 of 39 (64.1%) classified as non-CLL expressed high CD200 expression (≥30%). CD200 expression showed a high sensitivity (100%) and a low specificity (35.9%), and the accuracy was similar to that of Matutes score markers (range: 79.2%-86.7%); except SmIg that was 59.1%. The addition of CD200 to the Matutes score correctly identified 74 of 81 (91.4%) CLL cases including 9 of 16 atypical CLL cases. As per non CLL cases, 37 of 39 (94.9%) were correctly diagnosed by the modified system. Altogether, CD200 improved the diagnostic accuracy of Matutes score from 86.7% to 92.5% (P < .01). CONCLUSION: These results show that CD200 is a valuable, albeit not specific, CLL diagnostic marker. © 2018 International Clinical Cytometry Society.

RESUMEN

The aims of this study are to (i) examine a clustered metabolic syndrome composite score (MetScore) and fatness among college students across body mass index (BMI) categories, and (ii) determine whether fit individuals have lower MetScores, fewer individual metabolic syndrome components, and lower fatness than unfit individuals across BMI categories. A total of 1,795 participants aged  >18 years who participated in The FUPRECOL Study were selected for the present analyses. Handgrip strength was tested by a grip dynamometer and used to classify adults as fit or unfit. Among all participants, MetScore, percentage of body fat, and visceral adiposity increased linearly across the BMI categories among college students (all P < 0.001). Individuals who were overweight and fit had a lower MetScore (-0.6 SD; P = 0.02), body fat percentage (-2.6%; P < 0.001) and visceral adiposity (-0.2; P = 0.01) than unfit peers. Moderately fit obese individuals had significantly lower visceral fat levels than unfit obese peers (-3.0; P = 0.03). These results suggest that having adequate handgrip strength-a proxy of overall strength capacity-may attenuate obesity-related cardiometabolic risk. Moreover, weight loss should be recommended to all individuals with obesity, even among those who are currently considered fit.

RESUMEN

The aim of the study was to investigate the combined association of adherence to a Mediterranean diet (MedDiet) and muscular fitness (MF) with cardiometabolic health in collegiate students. The present cross-sectional analysis consisted of 1248 (714 females) healthy collegiate students (20.1 ± 2.7 years old). Adherence to a MedDiet was assessed by a KIDMED (Mediterranean Diet Quality Index) questionnaire. Standing broad jump, standing vertical jump, and isometric handgrip dynamometry were used as indicators of MF. The cardiometabolic profile was assessed using the following components: triglycerides, blood pressure, triglycerides, high-density lipoprotein (HDL)-cholesterol, glucose, and waist circumference. Analysis of covariance shows a significant difference in the cardiometabolic profile of both genders between the high MF/low MedDiet and high MF/optimal MedDiet groups, and the low MF/low MedDiet and low MF/optimal MedDiet groups (p < 0.001). No difference was found on cardiometabolic profile between high MF/optimal MedDiet and high MF/low MedDiet, both in males and females. Additionally, logistic regression shows that both female (odds ratio (OR) = 2.01; 95% confidence interval (CI): (1.8⁻3.7); p = 0.02) and male (OR = 3.38; 95% CI: (1.9⁻5.8); p < 0.001) participants in the optimal MedDiet/high MF group had the highest odds of expressing a healthier cardiometabolic profile as compared to those in the low MF/low MedDiet group. In conclusion, a combination of high MF levels and optimal adherence to a MedDiet is associated with a healthier cardiometabolic profile; however, high MF levels seem to circumvent the deleterious effects of having a low adherence to a MedDiet.

RESUMEN

The objective of this study was to determine the association of aerobic capacity with health-related quality of life in 121 subjects using the modified Bruce protocol as a predictor of maximum oxygen consumption (VO2 maximum) and the SF-36 quality of life questionnaire. The average maximum VO2 was 26.56 ± 12.67 mL/kg/min for men and 25.36 ± 10.72 mL/kg/min for women. There was a significant association between sex and maximum VO2 (p = 0.018). Physical function and social function were the variables with the highest average values in the total sample, and aerobic capacity explained 15.3% of the physical function. In conclusion, low maximum VO2 was found in both sexes, and there was a significant association of maximum VO2 with physical function, physical performance, general health, vitality, and social function.


Con el objetivo de determinar la asociación entre la capacidad aeróbica y la calidad de vida relacionada con la salud en adultos mayores, se encuestaron 121 personas en quienes se realizó el protocolo de Bruce modificado, como predictor del consumo máximo de oxígeno (VO2 máximo) y el cuestionario de calidad de vida SF-36. El promedio de VO2 máximo para hombres fue de 26,56±12,67 mL/kg/min, y para mujeres de 25,36±10,72 mL/kg/min, obteniéndose asociación significativa entre el sexo y el nivel de VO2 máximo (p=0,018), las dimensiones de función física y función social fueron las de mayor promedio en el total de la muestra y la capacidad aeróbica explica en un 15,3% la función física. Se concluye que el nivel pobre de VO2 máximo predomino en ambos sexos y existe asociación entre el nivel de VO2 máximo con las dimensiones de función física, desempeño físico, salud general, vitalidad y función social.

RESUMEN

Introducción: la optimización de la condición física en el adulto mayor disminuye los efectos del proceso de envejecimiento y las malas condiciones de vida en general. El objetivo es comparar la condición física funcional de adultos mayores en dos ciudades colombianas según variables sociodemográficas. Materiales y métodos: estudio de corte transversal en 428 adultos mayores asistentes a centros de atención al adulto mayor. Se indagaron características sociodemográficas. La condición física funcional se evaluó mediante la batería Senior Fitness. Se realizó una regresión logística bivariada estimando los odds ratio y su respectivo intervalo de confianza del 95 %. Resultados: los adultos mayores que viven en Tunja tuvieron mejores resultados, según la batería Senior Fitness, comparados con los de Barranquilla, tanto para hombres como para mujeres. En Tunja, las personas con edades entre 75 y 90 años tienen mayor riesgo de deficiencias en la resistencia aeróbica (or: 2.2; ic 95 %: 1.1-4.3). Se observa mayor probabilidad de disminución de la fuerza en miembros inferiores (or: 4.3; ic 95 %: 1.9-9.6), miembros superiores (or: 2.6; ic 95 %: 1.2-5.3) y de alteraciones del equilibrio (or: 2.1; ic 95 %: 1.1-4) en las personas que pertenecen al régimen subsidiado. En Barranquilla, la probabilidad de un imc alto es mayor en las mujeres que en los hombres (or: 2.2; ic 95 %: 1.1-4.4) y en los que no tienen una pareja (or: 2.6; ic 95 %: 1.2-5.6). Conclusión: las similitudes y diferencias encontradas en los sujetos de las dos ciudades plantean interrogantes que se deben resolver mediante estudios experimentales


Introduction: Optimization of physical condition in the elderly reduces, in general, the effects of aging and poor living conditions. The objective was to compare, using sociodemographic variables, the func-tional physical condition of older adults in two Colombian cities. Materials and Methods: A cross-sec-tional study was carried out, in both cities, of 428 older adults who attended elderly care centers. Their sociodemographic characteristics were investigated. Functional physical condition was evaluated by way of the Senior Fitness battery. A bivariate logistic regression was performed to estimate odds ratios and 95% confidence intervals. Results: For both men and women, according to the Senior Fitness battery, elderly living in Tunja had better results than those in Barranquilla. In Tunja, people belonging to the subsidized regime, and between 75 and 90 years old, had a greater risk of deficiencies in aerobic resis-tance (or: 2.2; ci 95%: 1.1­4.3), and a higher probability of decreasing strength in the lower limbs (or: 4.3; ci 95%: 1.9­9.6), upper limbs (or: 2.6; ci 95%: 1.2­5.3), and balance disturbances (or: 2.1; ci 95%: 1.1­4). In Barranquilla, the probability of a high body mass index was higher in women than in men (or: 2.2; ci95%: 1.1­4.4) and those who were not married (or: 2.6; ci 95%: 1.2­5.6). Conclusion: The similarities and differences found among the subjects of the two cities raise questions that must be addressed through experimental studies


Introdução: a otimização da condição física em idosos permite reduzir os efeitos do processo de envelhe-cimento e as precárias condições de vida em geral. O objetivo é comparar a condição física funcional de idosos em duas cidades colombianas segundo variáveis sociodemográficas. Materiais e métodos: estudo transversal com 428 idosos atendidos em Centros de Atenção ao Idoso das duas cidades. As caracterís-ticas sociodemográficas foram investigadas. A condição física funcional foi avaliada por meio da bate-ria Senior Fitness. Foi realizada regressão logística bivariada estimando o Odds Ratio e seu respectivo intervalo de confiança de 95%. Resultados: os idosos residentes em Tunja tiveram melhores resultados de acordo com a bateria Senior Fitness em comparação com os residentes de Barranquilla tanto para homens quanto para mulheres; em Tunja, pessoas com idades entre 75 e 90 anos têm um risco maior de deficiências na resistência aeróbia (or: 2,2; ic 95%: 1,1-4,3), se observa uma maior probabilidade de diminuição da força nos membros inferiores (or: 4,3; ic 95%: 1,9-9,6), membros superiores (or: 2,6; ic 95%: 1,2-5,3) e alterações de equilíbrio (or: 2,1; ic 95%: 1,1-4) em pessoas que pertencem ao regime subsidiado. Em Barranquilla, a probabilidade de um imc elevado é maior nas mulheres do que nos homens (or: 2,2; ic 95%: 1,1-4,4) e naqueles que não têm companheiro (or: 2,6; ic 95%: 1,2-5,6). Conclusão: as semelhanças e diferenças encontradas nos sujeitos das duas cidades levantam questões que devem ser resolvidas por meio de estudos experimentais
