Nicotine pouch product awareness, interest and ever use among US adults who smoke, 2021.

BACKGROUND: Tobacco-free nicotine pouches are one of the fastest growing tobacco product categories in the US market. However, data on awareness, appeal or ever use of these products in the USA are limited. METHODS: We surveyed a population-based sample of US adults who smoked (n=1018) between January and February 2021 about awareness, ever use of or interest in nicotine pouches. Multivariable logistic regression models explored the relationship between nicotine pouch variables and demographic and tobacco use characteristics. RESULTS: In early 2021, 29.2% of adults who smoked had ever seen or heard of nicotine pouches, 5.6% had ever tried pouches and 16.8% reported interest in using pouches in the next 6 months. Adults who smoked aged 18-44 years and those who had ever used smokeless tobacco (SLT) were more likely to be aware of nicotine pouches. Interest in using nicotine pouches was more prevalent among adult smokers who planned to quit within 6 months, attempted to quit before using counselling or another tobacco product and had ever used pouches. Among adults who smoked, those with more education had lower odds of ever using nicotine pouches while those who had attempted to quit before using traditional methods or ever used SLT had higher odds of ever use. CONCLUSION: Levels of awareness, appeal and trial of nicotine pouches among US adults who smoke were modest, with variation by age, education, quit plans and quit attempt methods. Continued surveillance is warranted, including among naïve users and users of other tobacco and nicotine products.

Perceived effectiveness of cancer screening among family medicine and internal medicine physicians in the United States.

Family and internal medicine physicians play an important role in cancer screening, yet there are limited data on their beliefs regarding effectiveness of screening tests, which may affect physicians' likelihood to recommend such tests. The study purpose was to assess current beliefs among family medicine and internal medicine physicians regarding effectiveness of various types of cancer screening. A national sample of 582 physicians from the American Medical Association's Physician Masterfile were surveyed. Participants were asked about their perceived effectiveness of screening for colon, lung, breast, prostate, and cervical cancer among average, healthy individuals. Chi-square tests were conducted to assess relationships between perceiving screening tests to be 'very effective in reducing cancer-related mortality' and demographic characteristics. A substantial majority of physicians perceived colonoscopy (83.8%) and Pap smear (82.9%) to be very effective. Perceiving low-dose computed tomography (LDCT), Pap smear, and prostate-specific antigen (PSA) as 'very effective' differed by gender, with females less likely to endorse LDCT and Pap smear but more likely to endorse PSA. Perceiving PSA as 'very effective' differed by age and graduation year, with younger or more recently graduated physicians being less likely to perceive PSA as 'very effective'. Non-Hispanic Black/African-American physicians were more likely to perceive mammography as 'very effective' than other groups. Physicians' perceived effectiveness about cancer screening tests varies widely and may influence their recommendations or usage of these tests. Understanding physicians' beliefs can help in improving uptake of evidence-based screening tests by providers and patients to promote early detection and successful treatment.
