INTRODUCTION/BACKGROUND:The use of alternative tobacco products (ATPs) is becoming increasingly popular among the youth. This study aimed to assess cigarette-only smoking, exclusive ATP use, and concurrent use (cigarettes and ATPs) among adolescents in Hong Kong. METHODS:We analyzed data of the Hong Kong School-based Survey on Smoking among Students 2012/13 from a representative sample of 45 857 secondary school students. Weighted prevalence of cigarette-only smoking, exclusive ATP use, and concurrent tobacco use were calculated. Multinomial logistic regression examined correlates of exclusive ATP use and concurrent use relative to cigarette-only smoking. Among current (past-30-days) cigarette smokers, multivariable logistic regression assessed whether ATP use was associated with nicotine dependence, quit intention and quit attempt. RESULTS:Overall, 5.8% of adolescents reported current tobacco use (2.1% cigarette-only smoking, 2.5% exclusive ATP use and 1.2% concurrent use). Compared with cigarette-only smoking, exclusive ATP use and concurrent tobacco use were associated with younger age, higher perceived family financial status, absence of cigarette smoking peers, poor knowledge about smoking and more frequent alcohol use. Among current cigarette smokers, ATP use was negatively associated with cigarette quit intention and quit attempt. CONCLUSIONS:ATP use was as prevalent as cigarette smoking among adolescents, and ATP users were different from cigarette smokers in many demographic and psychosocial factors. Tobacco control programs among youth should target different types of tobacco users and address all forms of tobacco products.

Aim and objective Injunctive norms about smoking, the perceived approval or acceptability of smoking from friends or wider peer group, have rarely been studied outside the Western world. We investigated injunctive norms and the associations with smoking susceptibility in adolescents in Hong Kong, where most adolescents are negative towards smoking. Methods In 2017/18, 7031 Secondary 1-5 (US grade 7-11) students (48.9% boys; mean age 14.3, SD 1.7) were surveyed.Students reported the perceived approval of smoking from good friends (disapprove/neutral/approve) and the perception of whether most secondary school students accepted smoking (no/yes). Smoking susceptibility referred to the lack of a firm intention not to smoke in the next 12 months, when good friends smoked in front, or when a good friend offered a cigarette. Logistic regression yielded adjusted odds ratios (AORs) of smoking susceptibility for injunctive norms in never smokers, adjusting for sociodemographic characteristics and school clustering effect. Results Overall, 1.3%, 21.1% and 77.5% of students perceived approval, neutral response and disapproval of smoking from good friends, respectively. Some (5.8%) perceived that most students accepted smoking. In never smokers (n=6472, 92.5%), compared with perceived disapproval from good friends, perceived neutral response (AOR 3.58, 95% CI 2.86-4.50) and approval (5.41, 2.93-9.97) were associated with smoking susceptibility. The perception that most students accepted smoking was also associated with smoking susceptibility (2.73, 2.02-3.71). Conclusions Injunctive norms were associated with smoking susceptibility in Hong Kong never smoking adolescents. Addressing misperceptions of others' approval or acceptability of smoking may help prevent adolescent smoking.

Objective/UNASSIGNED:To review available literature on the prevalence, risk factors, pathophysiology, and clinical outcomes of dysglycemia among people living with HIV (PLHIV) in sub-Saharan Africa (SSA). Methods/UNASSIGNED:Database search on PUBMED for eligible studies describing the prevalence, risk factors, pathophysiology, or clinical outcomes of dysglycemia in SSA PLHIV. Results/UNASSIGNED:Prevalence of diabetes mellitus (DM) and pre-DM among SSA PLHIV ranged from 1% to 26% and 19% to 47%, respectively, in 15 identified studies. Older age and an elevated body mass index (BMI) were common risk factors for dysglycemia. Risk factors potentially more specific to PLHIV in SSA included exposure to older-generation thymidine analogues or protease inhibitors, malnutrition at ART initiation, a failure to gain fat mass on treatment, and elevated serum lipids. There is evidence of higher nephropathy and neuropathy rates among PLHIV in SSA with comorbid DM compared to HIV-negative individuals with DM. Conclusion/UNASSIGNED:There is a need for longitudinal studies to enhance understanding of the risk factors for dysglycemia among PLHIV in SSA, further research into optimal therapies to reduce pre-DM progression to DM among SSA PLHIV, and studies of the burden and phenotype of diabetic complications and other health outcomes among PLHIV with comorbid DM in SSA.

Obstructive Sleep Apnea (OSA) is a common co-morbid condition in stroke patients. It represents a very important risk factor for stroke in addition to the other established ones such as hypertension, cardiovascular disease (CVD), hyperlipidemia, atrial fibrillation (AF), type 2 diabetes mellitus (T2DM), stress, smoking, and heavy drinking. Although in the United States the prevalence of OSA has somewhat decreased from the previous years, globally its prevalence remains constant, or in some cases, is on the rise. In this review we present the epidemiology for OSA in stroke populations and discuss the risk factors for stroke as well as the underlying pathogenetic mechanisms linking OSA, stroke and CVD. We also emphasize the more thorough evaluation and control of OSA in order to prevent the disabling side effects of a stroke, which not only compromises the physical and mental health of a person and increases the burden on families, but also adds a severe burden to national health economics. OSA should always be considered when assessing a patient with transient ischemic attacks (TIA). Work up and treatment for OSA will not only help prevent stroke with its devastating consequences, but will also help prevent CVD, and ameliorate co-morbid conditions such as diabetes and hypertension in these vulnerable populations.

BACKGROUND:School meals have the potential to improve diet quality for millions of students across the United States. OBJECTIVES:Evaluate the feasibility of the FAV5 program, which aims to strengthen school meals by increasing appeal of school meals and improving relationships within the team of child nutrition staff and with other staff/teachers at their schools. METHODS:Nutrition researchers facilitated partnerships between the following groups to develop and implement the FAV5 program: the child nutrition director (CND) and managers at seven elementary schools in a North Carolina county, teachers and principals at those schools, a chef, the North Carolina Department of Agriculture, and volunteers. RESULTS:The partnerships developed through the FAV5 program produced successful taste test events in seven elementary schools that generated enthusiasm around the school meals program and strengthened relationships. CONCLUSIONS:Engaging child nutrition staff and other community partners to plan and implement the FAV5 program in schools is feasible.

Prostate cancer survivors have unique needs that encompass diagnosis and treatment-related side effects. The provision of services for prostate cancer survivors is often limited by resources, time constraints in traditional clinic visits, payment, and patient and provider comfort with discussion of sensitive topics including sexual and urinary health, both of which are largely impacted by treatment. Telemedicine, the remote delivery of health care services using telephone, mobile, web, and video platforms, allows for potential cost savings, in addition to ease and comfort as patients can engage in telemedicine-based resources in the comfort of their homes. Furthermore, survivors prefer to seek information online making telemedicine approaches for prostate cancer survivorship care an ideal combination. A majority of the telemedicine-based interventions used the web, followed by telephone, mobile, and video platforms. In limited studies, telemedicine delivery of survivorship care has equal efficacy to traditional care delivery. In addition, although older patients did not use the Internet regularly, they were willing to adapt to Internet usage if it had the potential to increase their quality of life. Telemedicine delivery of prostate cancer survivorship care is acceptable, feasible, cost-effective, and potentially preferred by prostate cancer survivors. Additionally, it emphasizes knowledge, self-management and self-monitoring serving to increase self-efficacy. This specialized care allows for greater access and reaches a wider catchment area compared to traditional clinic visits. This is especially important as the number of prostate cancer survivors increases and healthcare systems incorporate alternatives to traditional in-person care.

The purpose of this research was to examine whether the local food environment, specifically the distance to the nearest sugar sweetened beverage (SSB) vendor, a measure of SSB availability and accessibility, was correlated with the likelihood of self-reported SSB consumption among a sample of fast food consumers. As part of a broader SSB behavior study in 2013-2014, respondents were surveyed outside of major chain fast food restaurants in New York City (NYC). Respondents were asked for the intersection closest to their home and how frequently they consume SSBs. Comprehensive, administrative food outlet databases were used to geo-locate the SSB vendor closest to the respondents' home intersections. We then used a logistic regression model to estimate the association between the distance to the nearest SSB vendor (overall and by type) and the likelihood of daily SSB consumption. Our results show that proximity to the nearest SSB vendor was not statistically significantly associated with the likelihood of daily SSB consumption, regardless of type of vendor. Our results are robust to alternative model specifications, including replacing the linear minimum distance measure with count of the total number of SSB vendors or presence of a SSB vendor within a buffer around respondents' home intersections. We conclude that there is not a strong relationship between proximity to nearest SSB vendor, or proximity to a specific type of SSB vendor, and frequency of self-reported SSB consumption among fast food consumers in NYC. This suggests that policymakers focus on alternative strategies to curtail SSB consumption, such as improving the within-store food environment or taxing SSBs.
