Sun protective behaviors and physical activity have the potential to reduce cancer risk. Walking is the most common type of physical activity in the United States, but it is unclear whether sun protective behaviors differ by categories of walking, such as leisure versus transportation walking. We examined whether sun protective behaviors varied by category or duration of walking in the 2015 National Health Interview Survey (N = 26,632), age ≥ 18 years. We used logistic regression to estimate sunscreen use, sun avoidance, and sun protective clothing use by four categories of walking (no reported walking, transportation only, leisure only, or walking for both) and separately for walking duration for the general population and sun-sensitive individuals. Prevalence of sunscreen use varied across walking categories and the odds of use were higher with longer walking duration for transportation and leisure compared to those who reported no walking. Sun avoidance varied across walking categories and the odds of avoidance were lower with longer duration leisure but not transportation walking. Sun protective clothing varied across walking categories and the odds of use were higher for longer duration transportation, but not leisure walking. Data on the concurrence of walking and sun protection is needed to further understand the relationship between these health behaviors. By examining leisure and transportation walking, we found variations in sun protective behaviors that may provide important insight into strategies to increase sun protection while promoting physical activity.

The current study characterizes associations between physical and social contexts of self-reported primary episodes of eating/drinking and sociodemographic and obesity-related variables in US adults. Multinomial logistic regression was used to analyse a nationally representative sample of adults from the 2006-2008 American Time Use Survey. Models identifying physical (where) and social (whom) contexts of primary eating/drinking episodes at the population level, controlling for demographic characteristics, weight status and time of eating, were conducted. A nationally representative sample of US adults (n 21 315). Eating/drinking with immediate family was positively associated with age (OR = 1·15 (95 % CI 1·04, 1·27) to 1·23 (95 % CI 1·09, 1·39)), education level (OR = 1·16 (95 % CI 1·03, 1·30) to 1·36 (95 % CI 1·21, 1·54)), obesity (OR = 1·13 (95 % CI 1·04, 1·22)), children in the household (OR = 3·39 (95 % CI 3·14, 3·66)) and time of day (OR = 1·70 (95 % CI 1·39, 2·07) to 5·73 (95 % CI 4·70, 6·99)). Eating in the workplace was negatively associated with female gender (OR = 0·65 (95 % CI 0·60, 0·70)) and children in the household (OR = 0·90 (95 % CI 0·83, 0·98)), while positively associated with non-white status (OR = 1·14 (95 % CI 1·01, 1·29) to 1·47 (95 % CI 1·32, 1·65)) and time of day (OR = 0·25 (95 % CI 0·28, 0·30) to 5·65 (95 % CI 4·66, 6·85)). Women (OR = 0·80 (95 % CI 0·74, 0·86)), those aged >34 years (OR = 0·48 (95 % CI 0·43, 0·54) to 0·83 (95 % CI 0·74, 0·93)) and respondents with children (OR = 0·69 (95 % CI 0·63, 0·75)) were less likely to eat in a restaurant/bar/retail than at home. Overweight and obese respondents had a greater odds of reporting an episode of eating in social situations v. alone (e.g. immediate family and extended family; OR = 1·13 (95 % CI 1·04, 1·22)) and episodes occurring in restaurant/bar/retail locations (OR = 1·12 (95 % CI 1·03, 1·23) to 1·14 (95 % CI 1·05, 1·24)). Findings underscore the multidimensional nature of describing eating/drinking episodes. Social and physical contexts for eating/drinking and their demographic correlates suggest opportunities for tailoring interventions related to diet and may inform intervention targeting and scope.

Background Sunburn is the strongest risk factor for melanoma and non-melanoma skin cancers. Adolescent sunburns are related to higher risk of developing melanoma later in life. Little is known about the association of sunburns and shade, particularly tree cover, around adolescent homes and schools. This linkage study assessed associations of adolescent self-reported sunburns with ambient ultraviolet radiation (UV) and tree cover. Methods We analyzed a U.S. national sample of parent–child dyads (n = 1333) from the 2014 Family Life, Activity, Sun, Health, and Eating (FLASHE) study conducted by the National Cancer Institute. The outcome was adolescent sunburns reported for the previous 12 months. GIS buffers around geocoded home and school addresses were used to summarize UV and tree cover. A sensitivity analysis assessed different UV measures and tree cover buffer distances. Logistic regression models estimated the adjusted odds of any sunburns for five models: (1) no environmental variables; (2) spatial variables of latitude and longitude; (3) UV; (4) tree cover; and, (5) a combined model with UV and tree cover. Covariates included common sunburn-related items such as sun protective behaviors, socio-demographics, and latitude. Model residuals were assessed for spatial dependency and clustering. Results Overall, 44% of adolescents reported any sunburns in the previous 12 months. For the bivariate associations, lower categories of UV were associated with any reported sunburns ( p-trend  = 0.002). Home tree cover was not associated with any reported sunburns ( p-trend  = 0.08), whereas schools with lower categories of tree cover were associated with sunburns ( p-trend  = 0.008). The adjusted odds of any sunburns by UV tertiles, as a linear tread, was 0.89 (0.76–1.05) ( p  = 0.17); school tree cover was: 0.91 (0.78–1.07) ( p  = 0.25). Neither UV nor tree cover, in a combined model, were significant. Sensitivity analyses resulted in the optimal buffer size of 200 m for summarizing tree cover. Spatial dependence of residuals was not significant and clustering was significant for about 6% or less of the sample in each model. Conclusions We did not find significant relationships between UV or tree cover and adolescent sunburns, when adjusted by sunburn-related covariates. Better contextual data about where sunburns occurred is needed to identify environmental correlates of sunburn.

Physical activity requirements (PAR; ie, courses required for graduation) have been proposed as a policy solution for increasing undergraduate physical activity. This study aimed to report prevalence of PAR among US colleges/universities participating in the American College Health Association-National College Health Assessment (ACHA-NCHA) and to understand whether these requirements were associated with campus characteristics. Data from the American College Health Association-National College Health Assessment II serial cross-sectional survey (2015–2019) were merged with researcher coded variables (2019): binary PAR status, nature of PAR (activity-based, conceptual, or combination), and number of courses required to fulfill the PAR. Logistic regression determined whether campus characteristics were associated with PAR in 2019. Nonparametric tests examined differences in nature and number of PAR courses. Of 379 schools, 59 (15.6%) had PAR, with 36 (61.0%) having activity-based PAR and 23 (39.0%) having a combination. Compared to public and four-year schools, private (OR=3.47 [1.77, 6.80]) and two-year schools (OR=6.55 [2.21, 19.45]) had significantly increased odds of having PAR. Private schools required significantly more PAR courses compared to public schools (2.42 vs. 1.73, P=.005). PAR were less prevalent in this sample than reported historically, indicating need for campus leadership attention to this issue. Research is needed to understand what barriers exist to implementing and maintaining PAR on college/university campuses, particularly among public and four-year schools. Understanding health promotion practices among ACHA member schools, which have made leadership commitments to promote student health, can provide greater knowledge of PAR barriers and best practices in schools across the United States and globally.

PurposeTo confirm that a multi-component physical activity index (PAI), with physical activity (PA)–related behaviors and performance measures, enhances PA assessment for adults with cancer history (“survivors”) vs. for the general population for key health variables.MethodsData from 2011 to 2014 NHANES were analyzed (n = 9620 adults, including 866 survivors). We generated PAI scores by calculating subscales for activity-related behaviors (i.e., moderate-to-vigorous PA and TV viewing hours/sedentary time) (n/8) and performance (i.e., cardiorespiratory fitness and muscle strength) (n/8), then combined for an overall PAI score (n/16 points). Dependent variables (self-reported health, multimorbidity, and functional limitations) were dichotomized and tested with logistic regression to estimate associations with PAI variables.ResultsSurvivors obtaining 22.5 + MET hours/week of PA were >5× more likely to report excellent health than non-exercisers (OR = 5.5, 95% CI 3.27–9.28). We observed a general decrease in likelihood of multimorbidity and functional limitations with increasing PA. Models with the combined score showed that higher PAI scores had larger positive associations with all three for all adults. Survivors with higher PAI scores were >30% more likely to report excellent self-rated health (OR = 1.3, 95% CI 1.2–1.4) and 20% less likely to report multimorbidity and functional limitations compared to survivors with lower PAI scores, considering covariates.ConclusionsGreater PA-related behavior and performance was beneficial for adults irrespective of cancer history. However, using a combined score elucidates unique needs and benefits for survivors vs. for general population.Implications for Cancer SurvivorsUsing a multi-component approach to PA assessment could help in developing validated tools to plan exercise programs and interventions for survivors.

Health misinformation is a problem on social media, and more understanding is needed about how users cognitively process it. In this study, participants’ accuracy in determining whether 60 health claims were true (e.g., “Vaccines prevent disease outbreaks”) or false (e.g., “Vaccines cause disease outbreaks”) was assessed. The 60 claims were related to three domains of health risk behavior (i.e., smoking, alcohol and vaccines). Claims were presented as Tweets or as simple text statements. We employed mouse tracking to measure reaction times, whether processing happens in discrete stages, and response uncertainty. We also examined whether health literacy was a moderating variable. The results indicate that information in statements and tweets is evaluated incrementally most of the time, but with overrides happening on some trials. Adequate health literacy scorers were equally certain when responding to tweets and statements, but they were more accurate when responding to tweets. Inadequate scorers were more confident on statements than on tweets but equally accurate on both. These results have important implications for understanding the underlying cognition needed to combat health misinformation online.

Objectives. We examined whether public schools in states with specific and stringent physical education (PE) laws, as assessed by the Physical Education–Related State Policy Classification System (PERSPCS), available on the Classification of Laws Associated with School Students (C.L.A.S.S.) Web site, reported more weekly PE time in the most recent School Health Policies and Programs Survey (SHPPS). Methods. Schools (n = 410) were grouped by their state’s PERSPCS time requirement scores (none, nonspecific requirement, or specific requirement). Average weekly school-level PE was calculated using the SHPPS-reported PE minutes. Weighted analyses determined if PE minutes/week differed by PERSPCS group. Results. Schools in states with specific requirement laws averaged over 27 and 60 more PE minutes/week at the elementary and middle school levels, respectively, compared with schools within states with nonspecific laws and over 40 and 60 more PE minutes per week, respectively, compared with elementary and middle schools in states with no laws. High school results were nonsignificant. Conclusions. Public health guidelines recommend at least 60 minutes of daily physical activity for children, and PE may further this goal. Strong codified law with specific time requirements for PE may be an important tool contributing toward adequate PE time and daily physical activity recommendations.

Abstract Background Population-based data from the National Health Interview Survey were examined to provide estimates of a wide range of health behaviors in cancer survivors (ie, physical activity, sun protection, alcohol use, cigarette and e-cigarette use, sleep, and diet) and trends over time. Methods Data were collected from 92 257 participants across 3 waves of the National Health Interview Survey. A total of 8050 participants reported having had cancer (2428 in 2005, 2333 in 2010, 3289 in 2015). Weighted and adjusted odds ratios (OR) between cancer survivors and controls were calculated using logistic and multivariable regressions in SPSS, and trend analyses from 2005 to 2015 were conducted. All statistical tests are 2-sided. Results After adjusting for demographics (2005-2015), cancer survivors, compared with controls, were more likely to wear sunscreen (OR = 1.41, 95% confidence interval [CI] = 1.32 to 1.51) and protect their skin (P < .001) and were less likely to tan indoors (OR = 0.81, 95% CI = 0.69 to 0.95), but reported less sleep (OR = 0.91, 95% CI = 0.85 to 0.98). In adjusted models, no differences were found for physical activity, sunburns, alcohol use, smoking, e-cigarette use, and diet. Smoking rates for cancer survivors decreased from 2005 to 2015 (P < .001) and physical activity increased (P = .02), but physical activity was not statistically significant after adjusting for multiple comparisons. All other health behavior rates for cancer survivors were unchanged from 2005 to 2015 (P > .14). Conclusion After adjusting for covariates, cancer survivors exhibited healthier sun protection, but not sleep behaviors, compared with controls. Cancer survivors (and controls) exhibited decreased smoking rates over time. These results may inform interventions focused on improving cancer control and prevention of other chronic conditions among cancer survivors.

The current research examined the association between state disfavoured tax on soda (i.e. the difference between soda sales tax and the tax on food products generally) and a summary score representing the strength of state laws governing competitive beverages (beverages that compete with the beverages in the federally funded school lunch programme) in US schools. The Classification of Laws Associated with School Students (CLASS) summary score reflected the strength of a state's laws restricting competitive beverages sold in school stores, vending machines, school fundraisers and à la carte cafeteria items. Bridging the Gap (BTG) is a nationally recognized research initiative that provided state-level soda tax data. The main study outcome was the states' competitive beverage summary scores for elementary, middle and high school grade levels, as predicted by the states' disfavoured soda tax. Univariate and multivariate analyses were conducted, adjusting for year and state. Data from BTG and CLASS were used. BTG and CLASS data from all fifty states and the District of Columbia from 2003 to 2010 were used. A higher disfavoured soda sales tax was generally associated with an increased likelihood of having strong school beverage laws across grade levels, and especially when disfavoured soda sales tax was >5 %. These data suggest a concordance between states' soda taxes and laws governing beverages sold in schools. States with high disfavoured sales tax on soda had stronger competitive beverage laws, indicating that the state sales tax environment may be associated with laws governing beverage policy in schools.

Sunburn is an important risk factor for skin cancer. Understanding sunburn prevalence and the contexts in which sunburn commonly occurs might help guide the development and implementation of sun safety interventions. Data from the 2024 National Health Interview Survey sample adult questionnaire were analyzed to describe the prevalence of one or more and four or more sunburns among U.S. adults during the previous 12 months and the percentages of U.S. adults who experienced their most recent sunburn while they were working at their job; intentionally tanning; exercising; spending time in, on, or near water; using sunscreen; or drinking alcohol. Overall, an estimated 88.1 million (35.1%) U.S. adults had at least one sunburn during the previous 12 months, and 18.8 million (7.5%) had four or more sunburns. Among adults who experienced sunburn during the previous year, spending time in, on, or near the water was the most frequently reported context of their most recent sunburn (60.6%); followed by exercising (24.7%); drinking alcohol (17.6%); intentionally tanning (15.9%); and working at their job (12.9%). Approximately one half (55.1%) of respondents reported that their most recent sunburn occurred despite using sunscreen. These findings can help guide research and activities to adapt, tailor, and expand evidence-based interventions to improve use of sun protection, prevent sunburn, and reduce skin cancer risk.
