RESUMO
Introducción: La alteración del clima planetario, atribuida directa o indirectamente a la actividad humana, que modifica la composición de la atmósfera mundial y se suma a la variabilidad natural del clima, es conocida como cambio climático global. Sus efectos en la salud, directos e indirectos, ya presentes, perturbarán a la mayoría de las poblaciones en las próximas décadas y pondrán en riesgo la vida y el bienestar de miles de millones de personas. Objetivo: Describir, a partir de una revisión, los principales riesgos para la salud humana derivados de la mayor frecuencia e intensidad de episodios de estrés térmico derivados del cambio climático. Métodos: Se realizó una revisión bibliográfica relativa a los efectos de la temperatura sobre la salud humana, así como su influencia sobre la mortalidad general, en el periodo 2008 hasta 2021, en las bases de datos Scopus, PubMed/Medline, SciELO, Ebsco, LiLACS, así como, otras fuentes y recursos de información disponibles en Internet. Se utilizó el vocabulario controlado del Descriptor en Ciencias de la Salud. Resultados: Se recuperaron 32 publicaciones sobre de la influencia del clima y sus cambios en la salud humana que plantearon, por lo general, que las altas temperaturas guardaron relación con el incremento de la mortalidad principalmente por enfermedades cardiovasculares, cerebrovasculares y respiratorias, se han convertido en un contribuyente considerable a la carga de morbilidad. Conclusiones: Las temperaturas extremas incrementan la morbilidad y mortalidad agudas, principalmente en grupos de riesgo. La promoción de una adecuada hidratación y el uso de ropas adecuadas, ayudará a las personas en la prevención de afecciones por las temperaturas extremas, erigiéndose en acciones individuales de protección contra los efectos de la mayor frecuencia e intensidad de eventos de estrés térmico asociado al cambio climático, a incorporar a la cotidianidad.
Introduction: The alteration of the planetary climate, attributed directly or indirectly to human activity, which modifies the composition of the world atmosphere and adds to the natural variability of the climate, is known as global climate change. Its direct and indirect health effects, already present, will disturb most populations in the coming decades and put the lives and well-being of billions of people at risk. Objective: To describe, based on a review, the main risks to human health derived from the greater frequency and intensity of episodes of thermal stress derived from climate change. Methods: A bibliographic review was carried out regarding the effects of temperature on human health, as well as its influence on general mortality, in the period 2008 to 2021, in the Scopus, PubMed/Medline, SciELO, Ebsco, LiLACS, as well as other information sources and resources available on the Internet. The controlled vocabulary descriptors in Health Sciences were used. Results: 32 publications on the influence of climate and its changes on human health were recovered, which generally stated that high temperatures were related to the increase in mortality, mainly due to cardiovascular, cerebrovascular and respiratory diseases, and have become a significant contributor to the burden of disease. Conclusions: Extreme temperatures increase acute morbidity and mortality, mainly in risk groups. The promotion of adequate hydration and the use of adequate clothing will help people in the prevention of conditions caused by extreme temperatures, establishing individual actions to protect against the effects of the greater frequency and intensity of heat stress events associated with climate change, to incorporate into daily life.
RESUMO
The observed increase of sexually transmitted diseases (STD) in Cuba aroused the interest of carrying out a study aimed at exploring risky sexual behaviours and attitudes, and histories of STD. A crosswise descriptive study was undertaken using a randomized sample taken from the universe of adolescent students in the City of Havana during 1995-96 school year. The sample was made up by 2,793 teenagers aged 11-19 years (1,370 females and 1,423 males). Previously trained experts linked to this field collected data by means of a structured interview which had been drawn up for this end. It was confirmed that more than half of adolescent students did not use condom in their sexual intercourse 57 had more than one sexual partner along the year, 40 believed it was difficult to keep only one partner whereas 35 had more than one sexual partner at the same time. Risk and protected sexual habits were noticed, with 39 for oral-genital and 21.4 for genital-anal. 22 for the interviewed adolescent said they had histories of STD.
