Parent-child discussions about sexual health are complicated, particularly with a male teen who identifies as gay, bisexual, or queer. Research from Dalmacio Dennis Flores of the University of Pennsylvania found that even when such conversations avoid heteronormative stereotypes, outside factors like mass media and religion -- those beyond the parents' control -- can reinforce them.
How do sex hormones and body weight affect emotional and cognitive well-being? To answer this question, a team of scientists led by Rachel Zsido and Julia Sacher analysed the data of 974 participants from a large population-based study by the Leipzig Research Centre for Civilization Diseases (LIFE). The researchers found that sex hormone oestradiol plays a crucial role in keeping the structure of networks in the female brain structurally intact and the memory healthy, especially in mid-life.
In 2017, the majority (58%) of the almost 27 000 newly reported hepatitis B cases in the European Union and European Economic Area were classified as chronic infections. This follows a consistent upward trend in reported chronic hepatitis B cases since 2008.
A randomised trial of more than 7,800 African women found that a type of contraceptive injection (intramuscular depot medroxyprogesterone acetate -- DMPA-IM) posed no substantially increased risk of HIV acquisition when compared with a copper intrauterine device (IUD) and a levonorgestrel (LNG) implant. The results of this first ever randomised trial in the area, published in The Lancet, counter 30 years of epidemiology research suggesting a potential association between some types of contraceptives and risk of acquiring HIV.
A new study has shown that the relationship between pornography and intimate partner experiences among heterosexual women is indirect and complex, in contrast to the more direct link among heterosexual men.
The US Preventive Services Task Force (USPSTF) recommends screening for HIV infection in adolescents and adults ages 15 to 65; in those younger or older at increased risk of infection; and in all pregnant people. The USPSTF routinely makes recommendations about the effectiveness of preventive care services and this statement is an update of its 2013 recommendation.
In a new recommendation, the US Preventive Services Task Force (USPSTF) recommends clinicians offer preexposure prophylaxis (PrEP) with effective antiretroviral therapy to people at high risk of acquiring HIV to decrease their risk of infection with the virus that causes AIDS.
Sexually active Australian secondary students tend to engage in responsible sexual behaviour but there is still room to improve knowledge and education for this group, according to a nationwide survey conducted by La Trobe University.
A new study by CUNY SPH researchers found that the adoption of the WHO's 2015 'Treat All' recommendation was followed by large increases in rapid initiation of antiretroviral therapy (ART) in six sub-Saharan African countries.
Inequality between men and women was not generally consolidated in Iberia during the Neolithic. However, situations progressively appeared that indicate dominance of men over women. Four important lines in which inequality between men and women can be investigated through successive historical periods are their access to funeral rites, the material conditions of their existence, the appearance of specific social roles for each of the genders and the growing association of men with violence.
