Similar to previous studies, exclusive breastfeeding was found to have great importance, since this practice protects the child's health and allows for a better development, despite unfavorable social and economic conditions. In particular, it seems that the protection conferred by breastfeeding is stronger when home conditions are poor, but this same condition presents an intervention opportunity, particularly the assurance of potable water provision for the infant when breastfeeding is not an option.
Objective. To assess the impact of occupational exposure to noise, as well as its relationship with other factors that can induce hearing loss. Material and methods. In January and February 1997, we conducted sonometry and dosimetry tests in a cement factory, as well as audiometric test in 85 cement workers, to identify sources of noise and evaluate the effect to noise exposure and other factors, of the prevalence of occupational hearing loss. Statistical analysis was conducted using measures of central tendency, bivariate analysis and polynominal regression models. Results. High noise levels were found in the crushing, crude milling, and cement milling sites. The highest individual dose corresponded to the packer job post. Fifty-five per cent of the study population presented some degree of hearing loss due to noise exposure. The cement processing area with the highest percentage of damaged workers was calcination. Conclusions. Our results show that noise is a serious risk factor in particular sites of cement factories, and also that an elevated number of hearing loss cases are due to occupational noise exposure in this industry; Our findings underscore the need for designing and implementing hearing protection programs, to assure the health and safety of cement workers.
Debido al aumento de casos y muerte por la enfermedad por el coronavirus (COVID-19) se generaron diferentes problemas de índole emocional, ante esta situación fue necesario evaluar el nivel de estrés en estudiantes universitarios. Se realizó un estudio cuantitativo transversal analítico. Participaron 182 estudiantes de las Facultades de Enfermería y Nutrición de la Universidad Autónoma del Estado de Morelos. Se utilizó la Escala de estrés percibido (PSS-14), conformada por 14 ítems sobre los niveles de estrés experimentados en el último mes, con una consistencia interna de 0.83. Los resultados evidencian que, el 50.34% y 4.14% de las mujeres tienen un nivel moderado y alto de estrés, respectivamente. Entre los factores asociados al aumento fueron: tener familiar diagnosticado con COVID-19 (RM=3,35 IC95% 1,67-6,69) y ser mujer (RM=2.61 IC95% 1,17-5,83). La detección de factores psicosociales que se presentan durante el confinamiento por la COVID-19, enfatiza la necesidad de desarrollar investigaciones con mayor profundidad, para favorecer la generación de intervenciones efectivas por medio de políticas públicas de salud mental en situaciones de confinamiento, expresando que la salud física es tan importante como la salud mental.
