Physical activity is often considered the responsibility of individuals. Recently, however, interest has developed in social ecological approaches that focus on a full spectrum of behavioral influences such as social and physical environments. A public park and recreation department has influence over some of the environmental and policy determinants of physical activity in a community. Therefore, the purpose of this exploratory examination of one community was to analyze the perceptions of people regarding physical activity, and to interpret the results from a social ecological perspective regarding how public parks and recreation staff might further promote active Lifestyles. Data came from six focus groups conducted during April-June 1999 in a community in the Southeast United States. The six groups included a women's walking group, teachers and school employees, YMCA members and employees, a Chamber of Commerce business group, a Community Coalition for Physical Activity group related to Healthy People 2000 objectives, and participants in senior (older adult) services. A total of 52 people who ranged in age from 22-75 years were involved in the group interviews. The participants were 46% African American and 54% European American with 70% of the participants women. Each of the focus groups was audio-taped and transcribed verbatim. A systematic method was used for coding and analyzing these qualitative data. Focus group participants expressed their perceptions about quality of life in the community and the physical activity opportunities that were available for themselves, their family, and friends. Constraints or barriers to participation were addressed. Although many of these constraints were individual in nature, they had environmental and policy implications. The potential for enhancing and promoting physical activity by public parks and recreation as well as local government, businesses, churches, schools, and health departments was described by the focus group members and was illustrated in a model that developed from these data. The results supported more efforts by the public park and recreation department, as well as a multisectoral approach, to providing physical activity opportunities in active communities. The major conclusions that emerged from these data that might be considered in other similar communities were: 1) Park and recreation departments, along with other community groups, can have an increasing role in creating a definition of an "active" community. The greatest challenge is not only to educate people that physical activity is good for them, but also to educate them about ways that they can become physically active. 2) A range of settings, facilities, and programs for children and adults as well as education for, and information about, physical activity must be available. 3) Physical activity does not occur in a vacuum. Issues such as transportation and accessibility must be accommodated regarding what already exists as well as in determining new initiatives. 4) Safety concerns are crucial in the design and planning of supportive physical activity environments. This safety includes physical safety as well as perceived safety. 5) Partnerships will be required to promote physical activity in a community. A joint effort with a shared vision and conjoint responsibilities is required. "It takes a village" to promote physical activity in a community. [ABSTRACT FROM AUTHOR]

Introduction: The impact of defining secondhand smoke exposure among nonsmokers using an expanded serum cotinine range is currently unknown.Methods: This study assessed the trends in secondhand smoke exposure prevalence among a nationally representative sample of 23,753 U.S. nonsmokers aged ≥3 years. Serum cotinine ranges of 0.05-10 ng/mL (established) and of 0.015-10 ng/mL (expanded) were analyzed in 2021 using data from the 2011-2018 National Health and Nutrition Examination Survey.Results: During 2011-2018, the percentage of people with a serum cotinine range of 0.05-10 ng/mL remained stable (25.3% to 24.6%) across most sociodemographic subgroups but declined significantly among adult Mexican Americans aged ≥20 years (23.9% to 14.1%). However, the percentage of people with serum cotinine range of 0.015-10 ng/mL significantly declined (58.3% to 52.3%) among male individuals (60.9% to 55.0%), among female individuals (56.2% to 50.0%), among adults aged ≥20 years (55.8% to 49.2%), among Mexican Americans (60.9% to 41.2%), among people with a college degree or higher (44.4% to 36.0%), among those who rented their housing (71.7% to 62.5%), among people not living with someone who smoked inside the home (56.1% to 50.0%), and among Mexican Americans aged ≥20 years (60.9% to 39.1%) (all p<0.05 for linear trend test).Conclusions: Expanding the serum cotinine range to 0.015-10 ng/mL more than doubles the estimated proportion of U.S. nonsmokers exposed to secondhand smoke. In contrast to a serum cotinine range of 0.05-10 ng/mL, it suggests that progress has been made in reducing population-level secondhand smoke exposure during 2011-2018, especially among nonsmokers experiencing lower exposure levels.

The use of any tobacco product by youths is unsafe, including electronic cigarettes (e-cigarettes) (1). Most e-cigarettes contain nicotine, which is highly addictive, can harm the developing adolescent brain, and can increase risk for future addiction to other drugs (1). E-cigarette use has increased considerably among U.S. youths since 2011 (1,2). Multiple factors have contributed to this increase, including youth-appealing flavors and product innovations (1-3). Amid the widespread use of e-cigarettes and popularity of certain products among youths, on February 6, 2020, the Food and Drug Administration (FDA) implemented a policy prioritizing enforcement against the manufacture, distribution, and sale of certain unauthorized flavored prefilled pod or cartridge-based e-cigarettes (excluding tobacco or menthol)., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest. No potential conflicts of interest were disclosed.

The use of tobacco products during adolescence increases the risk for adverse health effects and lifelong nicotine addiction. In 2014, an estimated 4.6 million middle and high school students were current users of any tobacco product, of whom an estimated 2.2 million were current users of two or more types of tobacco products. Symptoms of nicotine dependence are increased for multiple tobacco product users compared with single-product users. CDC and the Food and Drug Administration (FDA) analyzed data from the 2014 National Youth Tobacco Survey (NYTS) to determine how frequently (the number of days in the preceding 30 days) U.S. middle school (grades 6–8) and high school (grades 9–12) students used cigarettes, e-cigarettes, cigars, and smokeless tobacco products. Among current users (≥1 day during the preceding 30 days) in high school, frequent use (≥20 days during the preceding 30 days) was most prevalent among smokeless tobacco users (42.0%), followed by cigarette smokers (31.6%), e-cigarette users (15.5%), and cigar smokers (13.1%); a similar pattern was observed for those who used during all 30 days. Among current users in middle school, frequent use was greatest among smokeless tobacco users (29.2%), followed by cigarette smokers (20.0%), cigar smokers (13.2%) and e-cigarette users (11.8%). Current use of two or more types of tobacco products was common, even among students who used tobacco products 1–5 days during the preceding 30 days: 77.3% for cigar smokers, 76.9% for cigarette smokers, 63.4% for smokeless tobacco users, and 54.8% for e-cigarettes users. Preventing youths from initiating the use of any tobacco product is important to tobacco use prevention and control strategies in the United States. Monitoring the frequency and patterns of tobacco use among youths, including the use of two or more tobacco products, is important to inform evidence-based interventions to prevent and reduce all forms of tobacco use among youths.
