The DESI Legacy Imaging Surveys (http://legacysurvey.org/) are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Survey) that will jointly image ≈14,000 deg2 of the extragalactic sky visible from the northern hemisphere in three optical bands (g, r, and z) using telescopes at the Kitt Peak National Observatory and the Cerro Tololo Inter-American Observatory. The combined survey footprint is split into two contiguous areas by the Galactic plane. The optical imaging is conducted using a unique strategy of dynamically adjusting the exposure times and pointing selection during observing that results in a survey of nearly uniform depth. In addition to calibrated images, the project is delivering a catalog, constructed by using a probabilistic inference-based approach to estimate source shapes and brightnesses. The catalog includes photometry from the grz optical bands and from four mid-infrared bands (at 3.4, 4.6, 12, and 22 μm) observed by the Wide-field Infrared Survey Explorer satellite during its full operational lifetime. The project plans two public data releases each year. All the software used to generate the catalogs is also released with the data. This paper provides an overview of the Legacy Surveys project.

Purpose: The purpose of Cultivating Practices for Resilience (CPR) was to develop, implement, and evaluate college‐wide strategic initiatives to promote wellness and resilience and improve mental health outcomes in baccalaureate nursing students. Design and Methods: Six hundred and fifty‐four students were invited to complete a 24‐item survey over 3 weeks in 2021. Descriptive statistics/logistic regression were used for data analysis. Findings: One hundred and thirty‐one students completed the survey; 61% were sophomores. White students (p = 0.024) and males (p = 0.023) had higher intentions to refer colleagues to mental health services. Those perceiving CPR programming more helpful had higher intentions to refer (p < 0.001) and embrace the ANA's Healthy Nurse Healthy Nation™ campaign (p < 0.001). Practice Implications: Stronger strategic efforts are needed to help shape an academic culture for cultivating practices for resilience among baccalaureate nursing students, especially females and underrepresented population groups.

Objective: Examine receptivity and motivation to use/quit tobacco among college students after viewing Truth ads. Participants: Random sample of 10,000 college students invited to complete online survey February 2016 (8.5% response rate). Methods: Quasi-experimental. Participants (N = 854) watched four ads and answered survey items for each ad. Results: Students rated ad receptivity and decreased motivation to use tobacco higher for the Catmageddon ad than the others. Regardless of ad, men and current cigarette smokers reported lower receptivity. Younger age was associated with lower motivation to use tobacco for all ads. Tobacco users reported greater motivation to quit with the Catmageddon ad. Conclusions: College students were receptive to the Truth ads, and many indicated lower motivation to use tobacco. Men, older college students, and current cigarette smokers were less receptive to the ads, reinforcing the need to develop tailored campaigns to reach these subgroups. [ABSTRACT FROM AUTHOR]

Purpose: Rural adolescents engage in higher smoking and smokeless tobacco use rates than those from urban communities; urban adolescents are more likely to use e‐cigarettes. The study investigated whether place of residence (rural vs urban) is associated with tobacco use prevalence and change in prevalence among middle and high school students over time. Methods: We analyzed data from the National Youth Tobacco Survey (2011‐2016). Multiple logistic regression methods for weighted survey data assessed the relationship of place of residence with current tobacco product use over time, adjusting for demographics. Findings: There was no difference in rate of change in use of any tobacco product between rural and urban middle or high school students. Adjusting for age, sex, race/ethnicity, and survey year, both middle and high school rural students were more likely to use cigarettes and smokeless tobacco, whereas urban high school students were more likely to use hookah. Significant polynomial trends were observed for e‐cigarette and hookah use patterns, whereas linear changes in use patterns were detected for cigarette and smokeless tobacco use over time. Conclusions: Rural high school students are more likely to smoke cigarettes and use smokeless tobacco than their urban counterparts, although prevalence rates have decreased over time. However, use of hookah and e‐cigarettes among middle and high school students has increased over time regardless of place of residence. To stem the rapid increase in use of hookah and e‐cigarettes, comprehensive tobacco control policies are needed regardless of rural or urban location. [ABSTRACT FROM AUTHOR]

This study investigated the association between sociodemographic characteristics and public attitudes toward Tobacco 21 laws. Through a random telephone survey in 2017, 1,675 Kentucky adults were asked if they favored/opposed increasing the minimum legal age to purchase tobacco products from 18 to 21 years of age. Over half (57.9%) favored raising the minimum legal age for tobacco sales to 21 (95% confidence interval: [54.5, 61.2]). Multivariable logistic regression for weighted survey data was used to determine factors associated with support. In the adjusted analysis, older age, female sex, non-White, conservative political ideology (versus moderate), and support for a statewide smoke-free policy were each significantly associated with greater support for Tobacco 21. The results suggest multiple demographic and personal factors associated with support, even in a tobacco-growing state. Health care professionals, including nurses, must understand existing public attitudes to effectively advocate for tobacco policies in states with high tobacco use. [ABSTRACT FROM AUTHOR]

Background:Tobacco media campaigns are effective, but less is known regarding the impact on college students.Purpose:The purpose was to test the effects of an on-campus Tips television campaign on frequency and believability of ads recalled and to assess demographic and personal factors associated with believability.Methods:A quasi-experimental pre–post design was used to assess the 8-week campaign with 3 Tips ads. Two randomly selected cohorts of college students (N = 1593) from a large public university completed online surveys pre- and postcampaign. Group comparisons using chi-square tests, 2-samplettests, and logistic regression, controlling for residence or cohort, and predictors of believability using proportional odds modeling were examined.Results:Ads were recalled by significantly more students (68%) postcampaign. Believability for one or more ads was lower for males, undergraduates, those belonging to fraternity/sorority, and current polytobacco users (P < .05). Believability was greater for those who recalled seeing the ads more often (P < .05).Discussion:Subgroups of college students, including males and undergraduates, reported less ad believability, which should be considered when designing communication strategies.Translation to Health Education Practice:Considering the potential impact and cost-effective nature of on-campus TV media campaigns, these ads need to be integrated into current campus tobacco control strategies.

Objectives: (1) Compare social norms and perceived peer use between college student cigarette, e-cigarette, and/or hookah users and nonusers; and (2) determine variables associated with social influences.Participants: Undergraduate students attending a large university in the Southeast United States (N= 511).Methods: An April 2013 online survey assessed use of 3 types of tobacco, social norms, perception of peer use, number of smokers in life, exposure to secondhand smoke, and demographic characteristics.Results: Participants indicated greater acceptance of emerging tobacco products than for cigarettes and consistently overestimated the percent of peers who use various tobacco products. Males and current users had higher social norm scores for all 3 forms of tobacco.Conclusion: To counter marketing of alternative tobacco products, education about the dangers of their use needs to be implemented across college campuses as part of a comprehensive tobacco control strategy that also includes tobacco-free campus policies.

Objectives The purpose of this study was to assess attitudes and behaviors related to smoke-free policy among undergraduate student alcohol drinkers on a campus in a community with smoke-free bars. Design and Sample This was a secondary data analysis of a study in which participants completed mailed surveys assessing demographic characteristics, attitudes and behaviors related to alcohol and tobacco use and smoke-free policy ( n = 337). Opinion and behavior items were summarized descriptively; associations were examined using Kruskal Wallis tests and chi-square tests of association. Logistic regression tested for predictors of importance of smoke-free policy. Results Respondents were predominantly female and Caucasian; mean age 20.3 years. One fourth were current smokers. Seventy-nine percent said the community smoke-free law had no effect on frequency of visiting bars. Eighty-seven percent said smoke-free policy in campus buildings was 'somewhat' or 'very important.' Predictors of perceived importance of smoke-free policy included gender and smoking status. Conclusions Most smokers in this sample did not experience a change in their motivation to quit smoking or in number of cigarettes smoked daily. Implementation of a community smoke-free law did not reduce the likelihood of visiting bars. Women and nonsmokers were more likely to rate smoke-free campus policy as very important.

The purpose of this study was to determine the factors related to motivation to quit among smoking family members of lung cancer patients. Relatives of multidisciplinary lung cancer clinic patients were recruited during family members' treatment. Participants ( N=29) were primarily female and Caucasian. The items assessed included the effect of their relative's disease on motivation to quit, intent to quit in the next 6 months, stage of change, perceived risk from smoking, and attitudes about being approached about cessation. Most indicated that their relative's disease had increased motivation to quit smoking (71%); 72% planned to quit within 6 months. One fourth (28%) were in precontemplation stage of change; 65% in contemplation; and 7% in preparation. The average perceived risk of developing lung cancer was 6.3. Two thirds were glad or very glad that someone had talked with them about quitting; 91% thought it was somewhat or very appropriate to talk about cessation with family members of lung cancer patients. Motivation to quit smoking was positively correlated with stage of change and perceived lung cancer risk. Public health nurses who interact with families of lung cancer patients may be able to promote cessation in an at-risk group that is motivated to quit smoking. [ABSTRACT FROM AUTHOR]

Background:The prevalence of electronic cigarette use grows. Amid increased e-cigarette use nationwide, this paper attempts to identify underlying risk factors for the most vulnerable populations. Objective: The purpose of the study was to assess predictors of e-cigarette use among female current and former tobacco users of childbearingage--specifically to determine whether demographic factors, pregnancy status, conventional cigarette smoking, and perceived e-cigarette harm are associated with e-cigarette use. Reasons for using e-cigarettes were also measured. Methods: A cross-sectional, correlational design was used; 194 current and former female tobacco users, 18-45 years of age, from two university-affiliated prenatal clinics and one women's health clinic in Kentucky took part. Slightly more than half were pregnant. Age, race/ethnicity, education, pregnancy status, use history for cigarettes and e-cigarettes, and perception of health hazard from e-cigarettes were measured, and associations with e-cigarette use were made with Mann-Whitney U-tests or Spearman's rank correlations. Predictors of e-cigarette use were determined using proportional odds modeling. Results: Most current e-cigarette users were also current cigarette smokers (88%). Nearly half of current and former e-cigarette users were pregnant. Most women perceived e-cigarettes as a minor (38%) or moderate (31%) health hazard. In the proportional odds model, younger women were at greater risk for e-cigarette use, whereas minority women and those who were pregnant were less likely to be e-cigarette users. Discussion: Pregnant women were less likely to be more recent e-cigarette users, compared with nonpregnant women. However, nearly all current e-cigarette users were dual tobacco users, including pregnant women. It is both imperative and timely to determine the impact of e-cigarette use on maternal and infant health, thus improving healthcare provider confidence to discuss the health implications of e-cigarette use with their patients.
