Tobacco control policy and smoking among older Americans: An analysis of a nationally-representative longitudinal sample (1992-2014).
Smoking has decreased less rapidly among older adults than among the working age population in the United States. This study examines whether tobacco control policy, specifically smoke-free laws and increased cigarette prices, are associated with smoking cessation and lower smoking intensity among older adults. In addition, it considers whether the effect of smoke-free laws varied by labor force participation. ⋯ Neither the implementation of smoke-free laws nor increases in cigarette prices were associated with greater smoking cessation or lower smoking intensity. There was no evidence that labor force participation was associated with greater responsiveness to smoke-free laws. The results suggest that two of the most popular tobacco control policy tools in the US, smoke-free laws and cigarette prices, may be less effective among older adults.

Aggregation of behavioral risk factors to noncommunicable chronic diseases: A national school-based study with Brazilian adolescents.
There is an increasing interest in the study of the aggregation of risk factors for noncommunicable chronic diseases. However, there are no studies among adolescents stratified by alcohol use. This study investigated the aggregation of cardiovascular risk factors in adolescents considering the use or not of alcohol. ⋯ Aggregation of three cardiovascular risk factors was more likely to be observed among male adolescent alcohol users. Inadequate sleep and smoking habit tended to aggregate among alcohol users. This finding highlights the importance of public policies aiming to reduce alcohol consumption at early ages and, consequently, to decrease the risk of future morbimortality of noncommunicable chronic diseases.

Routine HIV testing in acute care hospitals: Changing practice to curb a local HIV epidemic in Vancouver, BC.
Early treatment of HIV infection increases life expectancy and reduces infectivity; however, delayed HIV diagnosis remains common. Implementation and sustainability of hospital-based routine HIV testing in Vancouver, British Columbia, was evaluated to address a local HIV epidemic by facilitating earlier diagnosis and treatment. Public health issued a recommendation in 2011 to offer HIV testing to all patients presenting to three Vancouver hospitals as part of routine care, including all patients admitted to medical/surgical units with expansion to emergency departments (ED). ⋯ People diagnosed in hospital were significantly more likely to be diagnosed with acute stage (aOR 1·96, 95% CI 1·19, 3·23) infection, particularly those diagnosed in the ED. This study provides practice-based evidence of the feasibility, acceptability, and effectiveness of implementing a recommendation for routine HIV testing among inpatient and emergency department admissions, as well as the ability to normalize and sustain this change. Routine hospital-based HIV testing can increase diagnoses of acute HIV infection and facilitate earlier initiation of antiretroviral treatment.

A three-dimensional dietary index (nutritional quality, environment and price) and reduced mortality: The "Seguimiento Universidad de Navarra" cohort.
Several healthy diet indices have been associated with mortality risk. However, the ideal diet should not only be healthy but also environmentally friendly and affordable. The study aimed to determine if a new Sustainable Diet Index (SDI), which takes into account the nutritional quality, environmental impacts and market price of diets, was associated with all-cause and cause-specific mortality. ⋯ SDI was positively correlated with beans and potato consumption but negatively correlated with red meat intake. Red and processed meats, fatty dairy products and fish consumption accounted for most of the variability in the SDI. Altogether, dietary patterns accounting not only for nutritional quality of the food but also the impact on the environment and affordability could still provide health benefits.

Lifestyle clusters related to type 2 diabetes and diabetes risk in a multi-ethnic population: The HELIUS study.
Little is known about how health-related behaviours cluster across different populations and how lifestyle clusters are associated with type 2 diabetes (T2D) risk. We investigated lifestyle clusters and their association with T2D in a multi-ethnic population. 4396 Dutch, 2850 South-Asian Surinamese, 3814 African Surinamese, 2034 Ghanaian, 3328 Turkish, and 3661 Moroccan origin participants of the HELIUS study were included (2011-2015). K-medoids cluster analyses were used to identify lifestyle clusters. ⋯ The pooled 'unhealthy' cluster was positively associated with prediabetes (OR: 1.34, 95%CI 1.21-1.48) and incident T2D (OR: 1.23, 95%CI 0.89-1.69), and negatively associated with prevalent T2D (OR: 0.80, 95%CI 0.69-0.93). Results were similar for most, but not all, ethnic-specific clusters. This illustrates that targeting multiple behaviours is relevant in prevention of T2D but that ethnic differences in lifestyle clusters should be taken into account.
