Objective To review the implications of recommending smokeless tobacco (ST) use as a harm reduction approach for low-income and middle-income countries (LMICs). Method Narrative review of published papers and other data sources (including conference abstracts and internet-based information) on the health risks posed by the use of ST products for individual smokers and for the population with a focus on their implications for LMICs. Results Swedish snus has a relatively lower toxicity profile than ST products available in other markets, including older products used in the US and products used in Africa and Asia. The experience with snus in Sweden provides information on the effects of snus use in a population where cigarette smoking was already culturally ingrained. However, population effects are likely to be different in those LMICs where smoking is not yet the dominant culturally accepted form of tobacco use. The total effect may be negative in countries where locally-popular ST products have substantially higher disease risks than Swedish snus and where there is limited regulatory and tobacco use surveillance capacity. Conclusions Issues relating to how populations in LMICs respond to marketing efforts, the risks of the dual use of ST and smoking, and the capacity to regulate ST products need to be considered in making decisions about harm reduction strategies in LMICs. The public health effects of supporting ST as a harm reduction strategy may vary substantively in countries with different pre-existing tobacco use patterns. Source

Introduction: This study assessed the perceptions and behaviors of US adults about the security of their protected health information (PHI). Methods: The first cycle of the fourth wave of the Health Information National Trends Survey was analyzed to assess respondents' concerns about PHI breaches. Multivariate logistic regression was used to assess the effect of such concerns on disclosure of sensitive medical information to a healthcare professional ( p<0.05). Results: Most respondents expressed concerns about data breach when their PHI was being transferred between healthcare professionals by fax (67.0%; 95% CI 64.2% to 69.8%) or electronically (64.5%; 95% CI 61.7% to 67.3%). About 12.3% (95% CI 10.8% to 13.8%) of respondents had ever withheld information from a healthcare provider because of security concerns. The likelihood of information withholding was higher among respondents who perceived they had very little say about how their medical records were used (adjusted OR=1.42; 95% CI 1.03 to 1.96). Conclusions: This study underscores the need for enhanced measures to secure patients' PHI to avoid undermining their trust. Source

OBJECTIVES: The association between parent-reported postnatal secondhand tobacco smoke exposure in the home and neurobehavioral disorders (attention-deficit/hyperactivity disorder, learning disabilities, and conduct disorders) among children younger than 12 years in the United States was examined using the 2007 National Survey on Children's Health. Excess neurobehavioral disorders attributable to secondhand smoke (SHS) exposure in the home in 2007 were further investigated. METHODS: The methods used in this study were multivariable logistic regression models that accounted for potential confounders and complex survey designs to evaluate associations. RESULTS: A total of 6% of 55 358 children (aged < 12 years), corresponding to a weighted total of 4.8 million children across the United States, were exposed to SHS in the home. The weighted prevalence and 95% confidence intervals of each of the children's neurobehavioral outcomes were 8.2% (7.5-8.8) with learning disabilities, 5.9% (5.5-6.4) with attention-deficit/hyperactivity disorder, and 3.6% (3.1-4.0) with behavioral and conduct disorders. Children exposed to SHS at home had a 50% increased odds of having ≥2 childhood neurobehavioral disorders compared with children who were not exposed to SHS. Boys had a significantly higher risk. Older children, especially those aged 9 to 11 years, and those living in households with the highest poverty levels were at greater risk. In absolute terms, 274 100 excess cases in total of these 3 disorders could have been prevented if children had not been exposed to SHS in their homes. CONCLUSIONS: The findings of the study, which are associational and not necessarily causal, underscore the health burden of childhood neurobehavioral disorders that may be attributable to SHS exposure in homes in the United States.

Background: Under the Family Smoking Prevention and Tobacco Control Act (FSPTCA), the Food and Drug Administration (FDA) banned the use of "Lights" descriptors or similar terms on tobacco products that convey messages of reduced risk. Manufacturers eliminated terms explicitly stated and substituted colour name descriptors corresponding to the banned terms. This paper examines whether the tobacco industry complied with or circumvented the law and potential FDA regulatory actions. Methods: Philip Morris retailer manuals, manufacturers' annual reports filed with the Massachusetts Department of Public Health, a national public opinion survey, and market-wide cigarette sales data were examined. Results: Manufacturers substituted "Gold" for "Light" and "Silver" for "Ultra-light" in the names of Marlboro sub-brands, and "Blue", "Gold", and "Silver" for banned descriptors in sub-brand names. Percent filter ventilation levels, used to generate the smoke yield ranges associated with "Lights" categories, appear to have been reassigned to the new colour brand name descriptors. Following the ban, 92% of smokers reported they could easily identify their usual brands, and 68% correctly named the package colour associated with their usual brand, while sales for "Lights" cigarettes remained unchanged. Conclusions: Tobacco manufacturers appear to have evaded a critical element of the FSPTCA, the ban on misleading descriptors that convey reduced health risk messages. The FPSTCA provides regulatory mechanisms, including banning these products as adulterated (Section 902). Manufacturers could then apply for pre-market approval as new products and produce evidence for FDA evaluation and determination whether or not sales of these products are in the public health interest.

Objective To examine the population effectiveness of nicotine replacement therapies (NRTs), either with or without professional counselling, and provide evidence needed to better inform healthcare coverage decisions. Methods A prospective cohort study was conducted in three waves on a probability sample of 787 Massachusetts adult smokers who had recently quit smoking. The baseline response rate was 46%; follow-up was completed with 56% of the designated cohort at wave 2 and 68% at wave 3. The relationship between relapse to smoking at follow-up interviews and assistance used, including NRT with or without professional help, was examined. Results About one-fourth of recent quitters at each wave reported to have relapsed by the subsequent interview. Odds of relapse were unaffected by use of NRT for >6 weeks either with (p=0.117) or without (p=0.159) professional counselling and were highest among prior heavily dependent persons who reported NRT use for any length of time without professional counselling (OR 2.68). Conclusions This study finds that persons who have quit smoking relapsed at equivalent rates, whether or not they used NRT to help them in their quit attempts. Cessation medication policy should be made in the larger context of public health, and increasing individual treatment coverage should not be at the expense of population evidence-based programmes and policies.
