Tobacco use during adolescence is a substantial problem and adolescents are at higher risk of addiction and prolonged use. To reduce the burden of tobacco-related morbidity and mortality, monitoring of adolescent tobacco use is imperative. We aimed to determine the prevalence of tobacco use among adolescents in urban and rural secondary schools in Enugu State, southeast Nigeria. ⋯ Nearly one in every five school-going adolescents currently uses at least one type of tobacco in Enugu State, southeast Nigeria. Prevalence of tobacco use is higher in rural schools and among boys in this setting. Most adolescent current smokers desire to quit and need smoking cessation support.

The Joint United Nations Programme on HIV/AIDS (UNAIDS) has developed an ambitious strategy to end the AIDS epidemic. After eight years of antiretroviral therapy (ART) program we assessed progress towards the UNAIDS 90-90-90 targets in Mbongolwane and Eshowe, KwaZulu-Natal, South Africa. ⋯ In this context of high HIV prevalence, significant progress has been achieved with regards to reaching the UNAIDS 90-90-90 targets. The third 90, viral suppression in people on ART, was achieved among women and men. However, gaps persist in HIV diagnosis and ART coverage particularly in men and individuals younger than 30 years. Achieving 90-90-90 is feasible but requires additional investment to reach youth and men.

Daily activity data are by nature compositional data. Accordingly, they occupy a specific geometry with unique properties that is different to standard Euclidean geometry. This study aimed to estimate the difference in adiposity associated with isotemporal reallocation between daily activity behaviours, and to compare the findings from compositional isotemporal subsitution to those obtained from traditional isotemporal substitution. ⋯ The compositional isotemporal model caters for the constrained and therefore relative nature of activity behaviour data and enables all daily behaviours to be included in a single statistical model. The traditional model treats data as real variables, thus the constrained nature of time is not accounted for, nor reflected in the findings. Findings from compositional isotemporal substitution support the importance of MVPA to children's health, and suggest that while interventions to increase MVPA may be of benefit, attention should be directed towards strategies to avoid decline in MVPA levels, particularly among already inactive children. Future applications of the compositional model can extend from pair-wise reallocations to other configurations of time-reallocation, for example, increasing MVPA at the expense of multiple other behaviours.

Access to direct-to-consumer genetic testing services has increased in recent years. However, disparities in knowledge and awareness of these services are not well documented. We examined awareness of genetic testing services by rural/urban and racial/ethnic status. ⋯ Rural-urban and racial-ethnic differences exist in awareness of direct-to-consumer genetic testing. These differences may translate into disparities in the uptake of genetic testing, health behavior change, and disease prevention through precision and personalized medicine.

In 2011-2012, an outbreak of measles occurred in Ecuador. This study sought to ascertain which population characteristics were associated. ⋯ In Ecuador, the parishes with the highest percentage of indigenous populations and those with the lowest vaccination coverage were the most vulnerable during the measles outbreak.
