Breasts as a perceived barrier to physical activity in Mexican women: A cross-sectional study.

BACKGROUND: Scarce evidence exists on barriers to physical activity in Mexican women. Despite evidence from other countries, no research has investigated the influence of the breast on PA in this population. OBJECTIVE: To determine the association between the breast and physical activity in Mexican women. DESIGN: Cross-sectional observational study. METHODS: Volunteers were 279 Mexican women from Veracruz, Durango, and Baja California states, who completed a paper survey of their demographics, brassiere characteristics, breast pain, and frequency and amounts of weekly physical activity. RESULTS: The first barrier to physical activity was time constraints, followed by breast-related issues. Breast pain was reported by 47.1% of women, and the breast as a barrier to physical activity participation was reported by 30.6%. Responses, such as "I am embarrassed by excessive breast movement" and "My breasts are too big" were the most frequently reported breast-related barriers to physical activity. Breast pain was associated with the menstrual cycle and exercise. Breast health knowledge and pain intensity were unrelated to moderate- and vigorous-intensity physical activity. The 36.4% and 6.7% of women did not meet weekly moderate- and vigorous-intensity physical activity guidelines, respectively. Weekly moderate- and vigorous-intensity physical activity was similar between women reporting breast pain and those who did not. CONCLUSIONS: Because the breast was the second most significant barrier to physical activity, it is imperative to increase breast health knowledge in Mexican women to reduce impediments to physical activity.

Perception of Mexican women regarding their breasts as a barrier to physical activityPhysical activity provides numerous health benefits, sometimes associated with reversing or delaying several diseases. However, barriers to increasing physical activity in women remain, as the breast is an anatomical aspect that is unique to women. Breast pain has been reported in more than 50% of women who perform physical exercise. Therefore, the study aimed to determine the associations between breast characteristics and barriers to physical activity in Mexican women. Two hundred and seventy-nine women from three Mexican states voluntarily participated in the study. They answered survey questions on the history of bra use, barriers to physical activity, and essential demographic characteristics. The main findings of this study were that issues related to the breasts were reported as the second barrier to physical activity participation. In addition, time constraints were reported as the main reason impeding physical activity participation. Public health initiatives should support attempts to increase breast satisfaction among women of all breast sizes to stimulate engagement in physical activity throughout their lives.

Identification of a triatomine infected with Trypanosoma cruzi in an urban area of the state of Veracruz, Mexico: A comprehensive study.

Chagas disease, considered a neglected disease, was initially confined to rural localities in endemic areas; however, in recent years through the process of urbanization and migration of infected people, the disease is gaining importance in urban environments. The presence of the vector in urban areas in most cases is due to the passive transport of vectors, but recently, its presence seems to be linked to vector adaptation processes associated with climate change. This paper reports the occurrence of an infected triatomine in the peridomicile of a house in an urban area of Córdoba, Veracruz, Mexico, where the species found is described, the molecular characteristics and resistance to BZN and NFX of the Trypanosoma cruzi isolate obtained, as well as serological data of the dwelling inhabitants. These urban disease scenarios make it possible to generate new scientific knowledge and enable the creation of new control strategies for Chagas disease vectors.

Introducción: La disminución de la función del sistema inmune con la edad es asociada a la incidencia de enfermedades infecciosas del tracto respiratorio superior; por otro lado, el ejercicio físico ha sido ampliamente recomendado para la salud. Sin embargo se requiere aún fundamentar con mayor exactitud los efectos del ejercicio físico en el sistema inmunológico en adultos mayores. Objetivo: Evaluar el efecto de un programa de hidrogimnasia sobre la concentración sérica de Inmunoglobulina A (IgA) en adultas mayores. Métodos: 26 participantes fueron asignadas aleatoriamente a un grupo experimental (n: 16) y un grupo control (n: 10). Se determinó la concentración sérica de IgA por nefelometría (BN2 Analyser, DADE Behring). Las sesiones de hidrogimnasia se realizaron cinco veces por semana durante 12 semanas; el ejercicio fue aeróbico a una intensidad de 50-60% de la frecuencia cardíaca máxima controlada por telemetría (Polar-FT7). Resultados: Se utilizó la prueba de ANOVA, indicando no interacción significativa (p: 0,797). El porcentaje de cambio resultó de Δ% = -6,7 mg/dL del grupo experimental en comparación con el grupo control Δ% = -7,4 mg/dL. Conclusiones: Un programa de tres meses de hidrogimnasia en mujeres no mejora significativamente los niveles de IgA. Sin embargo, los datos refieren una mejora positiva el porcentaje de cambio A%.

Reliability of the maximal oxygen uptake following two consecutive trials by indirect calorimetry / Confiabilidad del consumo máximo de oxigeno evaluado en pruebas de esfuerzo consecutivas mediante calorimetría indirecta

Background: The maximal oxygen uptake (VO2máx) assessment by indirect calorimetry is the most reliable method to determine VO2máx, but when repeated tests are conducted, the results have been controversial. Aim: To determine the reliability of the maximal oxygen uptake (VO2máx) in healthy adults following two consecutive trials with 10 min rest between trials using the Bruce protocol. Methods: Participants were 6 males apparently healthy physically active (Mean age=23,4±1,3 years), who performed twice the Bruce protocol and after reaching their VO2máx in the first trial they stepped down the treadmill and rested seated on a chair during 10 min. Results: The data analysis showed high reproducibility values between tests, indicated by the correlation coefficient Pearson product moment and R squared with confidence intervals at 95% (CI95%), the correlation of the maximum oxygen consumption was VO2máx =0.907 with a R2 =0.823, the maximum heart rate was HRmáx=0.786, with R2 =0.618 and the rate of ventilation and carbon dioxide elimination was VE/VCO2 =0.868, with an R2 =754. No adverse effects were reported during the 10 min rest between trials. Conclusion: Resting 10 min between consecutive maximal exercise tests using Bruce protocol treadmill tests does not affect VO2máx in healthy young adults. It is feasible and reliable to perform maximal treadmill tests in a single session without adverse effects for the participant (AU)

Introducción: La evaluación del con consumo máximo de oxígeno (VO2máx) por calorimetría indirecta es el método más confiable aun sin embargo los resultados al determinar el VO2máx cuando se realizan pruebas repetidas han resultado controversiales. Objetivo: Determinar la confiabilidad del consumo máximo de oxígeno (VO2máx) obtenido mediante dos pruebas de esfuerzo consecutivas utilizando el protocolo de Bruce en sujetos sanos que descansaron 10 min entre cada prueba.

Reliability of the maximal oxygen uptake following two consecutive trials by indirect calorimetry.

BACKGROUND: The maximal oxygen uptake (VO2máx) assessment by indirect calorimetry is the most reliable method to determine VO2máx, but when repeated tests are conducted, the results have been controversial. AIM: To determine the reliability of the maximal oxygen uptake (VO2máx) in healthy adults following two consecutive trials with 10 min rest between trials using the Bruce protocol. METHODS: Participants were 6 males apparently healthy physically active (Mean age=23,4±1,3 years), who performed twice the Bruce protocol and after reaching their VO2máx in the first trial they stepped down the treadmill and rested seated on a chair during 10 min. RESULTS: The data analysis showed high reproducibility values between tests, indicated by the correlation coefficient Pearson product moment and R squared with confidence intervals at 95% (CI95%), the correlation of the maximum oxygen consumption was VO2máx =0.907 with a R2=0.823, the maximum heart rate was HRmáx=0.786, with R2=0.618 and the rate of ventilation and carbon dioxide elimination was VE/VCO2=0.868, with an R2=754. No adverse effects were reported during the 10 min rest between trials. CONCLUSION: Resting 10 min between consecutive maximal exercise tests using Bruce protocol treadmill tests does not affect VO2máx in healthy young adults. It is feasible and reliable to perform maximal treadmill tests in a single session without adverse effects for the participant.
