Project description:ImportanceThe US Food and Drug Administration has classified tanning beds as carcinogenic. Most states have enacted legislation to prevent or create barriers for minors accessing tanning establishments. Determining tanning salon compliance with legislation would provide an indication of the influence of legislation at preventing exposure to the carcinogen in minors.ObjectivesTo investigate compliance rates in the 42 states and the District of Columbia with legislation restricting tanning bed use in minors and to identify differences in compliance based on population, regional location, salon ownership, age group being regulated, and time since the law was enacted.Design, setting, and participantsThis investigation was a cross-sectional telephone survey conducted between February 1, 2015, and April 30, 2016, by callers posing as minors attempting to schedule a tanning appointment. The setting was tanning salons in the 42 states and the District of Columbia that currently have legislation restricting tanning bed use in minors. Included in the study were 427 tanning salons, 10 randomly selected from each state or territory with tanning legislation.Main outcomes and measuresOverall compliance of tanning salons with state tanning legislation and differences in compliance based on community population, regional location, independent vs chain tanning salon, age group being regulated, and time since the law was enacted.ResultsOf the 427 tanning salons surveyed, overall noncompliance with state legislation was 37.2% (n = 159). There were more noncompliant tanning salons in rural locations (45.5%; 95% CI, 37.5%-53.7%; P = .009), southern regions of the United States (49.4%; 95% CI, 41.4%-57.4%; P = .001), independently owned salons (43.9%; 95% CI, 37.3%-50.6%; P = .003), states with younger age groups being regulated (53.5%; 95% CI, 45.7%-61.2%; P < .001), and states with more than one tanning regulation (50.0%; 95% CI, 42.0%-58.0%; P < .001). No difference was found based on time since the law was enacted.Conclusions and relevanceCompliance with state legislation aimed at limiting tanning bed use among US minors is unsatisfactory, indicating that additional efforts to enforce the laws and education of the harmful effects of UV tanning are necessary, especially in rural, independently owned, and tanning salons in southern regions, which have decreased compliance rates.
Project description:Palliative care aims to improve quality of life for people with serious illness and their families. One potential barrier to palliative care uptake is inaccurate knowledge and/or negative beliefs among the general population, which may inhibit early interest in, communication about, and integration of palliative care following subsequent illness diagnosis. We explored knowledge and beliefs about palliative care among the general public using nationally-representative data collected in 2018 as part of the cross-sectional Health Information National Trends Survey. Only individuals who had heard of palliative care (n = 1,162, Mage = 51.8, 64% female) were queried on knowledge and beliefs. We examined whether self-assessed level of awareness of palliative care (i.e., knowing a little vs. enough to explain it) was associated with the relative likelihood of having accurate/positive beliefs, inaccurate/negative beliefs, or responding "don't know" to questions about palliative care. Respondents who indicated knowing a lot about palliative care had more accurate versus inaccurate knowledge than those who knew a little on only two of six items and more positive attitudes on only one of three items. In particular, respondents with greater awareness were equally likely to report that palliative care is the same as hospice and requires stopping other treatments, and equally likely to believe that palliative care means giving up and to associate palliative care with death. Those with higher awareness were less likely than those with lower awareness to respond "don't know," but greater awareness was not necessarily associated with having accurate or positive beliefs about palliative care as opposed to inaccurate or negative beliefs. Thus, even members of the general public who perceived themselves to know a lot about palliative care were often no less likely to report inaccurate knowledge or negative beliefs (versus accurate and positive, respectively). Findings suggest a need to improve awareness and attitudes about palliative care.
Project description:Understanding current pubic hair removal (PHR) practices is vital for public health, given the prevalence among U.S. adults. This study updates the understanding of PHR practices, motivations, and correlates in a nationally representative sample of adult men. In April 2023, through a probability-based internet panel survey (Ipsos KnowledgePanel®), we found that nearly half (46.7%) of respondents reported lifetime PHR, with 29.2% reporting PHR in the past 30 days. Statistically significant differences were observed in sexual orientation, age, socioeconomic status, sexual activity, and social media use. A higher proportion of Gay and Bisexual men (GBM) reported lifetime PHR (76.5%) compared with heterosexual men (44.6%), with GBM having nearly 3 times greater odds of reporting lifetime PHR (OR = 2.891, 95%CI [1.2, 6.7]). Being sexually active in the past month statistically significantly predicted both lifetime PHR (OR = 1.884, 95%CI [1.2, 2.9]) and past 30-day PHR (OR = 2.849, 95%CI [1.8, 4.6]). Age also emerged as a significant predictor, as men aged 25 to 34 years (OR = 2.275, 95%CI [1.0, 5.0]) and 45 to 54 years (OR = 2.493, 95%CI [1.1, 5.6]) had higher odds of reporting lifetime PHR compared with those aged 18 to 24 years. This study provides valuable insights and updated national data on the prevalence, methods, and frequency of PHR among men in the United States. Given the correlations between PHR practices and factors such as sexual orientation, sexual activity, and age, these findings can equip educators and health care providers with data to foster better health outcomes through acknowledging and addressing the interplay between individual choices and broader social and cultural factors.
Project description:BackgroundLaboratory studies have linked nickel with the pathogenesis of cardiovascular disease (CVD); however, few observational studies in humans have confirmed this association.ObjectiveThis study aimed to use urinary nickel concentrations, as a biomarker of environmental nickel exposure, to evaluate the cross-sectional association between nickel exposure and CVD in a nationally representative sample of U.S. adults.MethodsData from a nationally representative sample (n = 2702) in the National Health and Nutrition Examination Survey 2017-20 were used. CVD (n = 326) was defined as self-reported physicians' diagnoses of coronary heart disease, angina, heart attack, or stroke. Urinary nickel concentrations were determined by inductively coupled plasma mass spectrometry. Logistic regression with sample weights was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of CVD.ResultsUrinary nickel concentrations were higher in individuals with CVD (weighted median 1.34 μg/L) compared to those without CVD (1.08 μg/L). After adjustment for demographic, socioeconomic, lifestyle, and other risk factors for CVD, the ORs (95% CIs) for CVD compared with the lowest quartile of urinary nickel were 3.57 (1.73-7.36) for the second quartile, 3.61 (1.83-7.13) for the third quartile, and 2.40 (1.03-5.59) for the fourth quartile. Cubic spline regression revealed a non-monotonic, inverse U-shaped, association between urinary nickel and CVD (Pnonlinearity < 0.001).ConclusionsNickel exposure is associated with CVD in a non-monotonic manner among U.S. adults independent of well-known CVD risk factors.Supplementary informationThe online version contains supplementary material available at 10.1007/s12403-023-00579-4.
Project description:BackgroundThe 24-h rest and activity behaviors (i.e., physical activity, sedentary behaviors and sleep) are fundamental human behaviors essential to health and well-being. Functional principal component analysis (fPCA) is a flexible approach for characterizing rest-activity rhythms and does not rely on a priori assumptions about the activity shape. The objective of our study is to apply fPCA to a nationally representative sample of American adults to characterize variations in the 24-h rest-activity pattern, determine how the pattern differs according to demographic, socioeconomic and work characteristics, and examine its associations with general health status.MethodsThe current analysis used data from adults 25 or older in the National Health and Nutrition Examination Survey (NHANES, 2011-2014). Using 7-day 24-h actigraphy recordings, we applied fPCA to derive profiles for overall, weekday and weekend rest-activity patterns. We examined the association between each rest-activity profile in relation to age, gender, race/ethnicity, education, income and working status using multiple linear regression. We also used multiple logistic regression to determine the relationship between each rest-activity profile and the likelihood of reporting poor or fair health.ResultsWe identified four distinct profiles (i.e., high amplitude, early rise, prolonged activity window, biphasic pattern) that together accounted for 86.8% of total variation in the study sample. We identified numerous associations between each rest-activity profile and multiple sociodemographic characteristics. We also found evidence suggesting the associations differed between weekdays and weekends. Finally, we reported that the rest-activity profiles were associated with self-rated health.ConclusionsOur study provided evidence suggesting that rest-activity patterns in human populations are shaped by multiple demographic, socioeconomic and work factors, and are correlated with health status.
Project description:BackgroundFew population-based data on the prevalence of eating disorders exist, and such data are especially needed because of changes to diagnoses in the DSM-5. This study aimed to provide lifetime and 12-month prevalence estimates of DSM-5-defined anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED) from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions.MethodsA national sample of 36,306 U.S. adults completed structured diagnostic interviews (Alcohol Use Disorder and Associated Disabilities Interview Schedule-5).ResultsPrevalence estimates of lifetime AN, BN, and BED were 0.80% (SE 0.07%), 0.28% (SE 0.03%), and 0.85% (SE 0.05%), respectively. Twelve-month estimates for AN, BN, and BED were 0.05% (SE 0.02%), 0.14% (SE 0.02%), and 0.44% (SE 0.04%). The odds of lifetime and 12-month diagnoses of all three eating disorders were significantly greater for women than for men after adjusting for age, race and/or ethnicity, education, and income. Adjusted odds ratios (AORs) of lifetime AN diagnosis were significantly lower for non-Hispanic black and Hispanic respondents than for white respondents. AORs of lifetime and 12-month BN diagnoses did not differ significantly by race and/or ethnicity. The AOR of lifetime, but not 12-month, BED diagnosis was significantly lower for non-Hispanic black respondents relative to that of non-Hispanic white respondents; AORs of BED for Hispanic and non-Hispanic white respondents did not differ significantly. AN, BN, and BED were characterized by significant differences in age of onset, persistence and duration of episodes, and rates of current obesity and psychosocial impairment.ConclusionsThese findings for DSM-5-defined eating disorders, based on the largest national sample of U.S. adults studied to date, indicate some important similarities to and differences from earlier, smaller nationally representative studies.
Project description:ObjectiveTo determine effectiveness of receipt of care from podiatrist and lower extremity clinician specialists (LEC specialists) on diabetes mellitus (DM)-related lower extremity amputation.Data sourcesMedicare 5 percent sample claims, 1991-2007.Study designIndividuals with DM-related lower extremity complications (LECs) were followed 6 years. Visits with podiatrists, LEC specialists, and other health professionals were tracked to ascertain whether receipt of such care reduced the hazards of an LEC amputation.Data collectionIndividuals were stratified based on disease severity, Stage 1--neuropathy, paresthesia, pain in feet, diabetic amyotrophy; Stage 2--cellulitis, charcot foot; Stage 3--ulcer; Stage 4--osteomyelitis, gangrene.Principal findingsHalf the LEC sample died within 6 years. More severe lower extremity disease increased risk of death and amputation. Persons visiting a podiatrist and an LEC specialist within a year before developing all stage complications were between 31 percent (ulceration) and 77 percent (cellulitis and charcot foot) as likely to undergo amputation compared with individuals visiting other health professionals.ConclusionsIndividuals with an LEC had high mortality. Visiting both a podiatrist and an LEC specialist in the year before LEC diagnosis was protective of undergoing lower extremity amputation, suggesting a benefit from multidisciplinary care.
Project description:Understanding factors that influence those who are initially COVID-19 vaccine hesitant to accept vaccination is valuable for the development of vaccine promotion strategies. Using Ipsos KnowledgePanel®, we conducted a national survey of adults aged 18 and older in the United States. We created a questionnaire to examine factors associated with COVID-19 vaccine uptake over a longitudinal period ("Wave 1" in April 2021 and "Wave 2" in February 2022), and utilized weighted data provided by Ipsos to make the data nationally representative. Overall, 1189 individuals participated in the Wave 1 survey, and 843 participants completed the Wave 2 survey (71.6% retention rate). Those who intended to be vaccinated as soon as possible ("ASAP") were overwhelmingly vaccinated by Wave 2 (96%, 95% CI: 92% to 100%). Of those who initially wished to delay vaccination until there was more experience with it ("Wait and See"), 57% (95% CI: 47% to 67%) were vaccinated at Wave 2. Within the "Wait and See" cohort, those with income <$50,000 and those who had never received the influenza vaccine were significantly less likely to be vaccinated at Wave 2. Among those who initially indicated that they would not receive a COVID-19 vaccine ("Non-Acceptors"), 28% (95% CI: 21% to 36%) were vaccinated at Wave 2. Those who believed COVID-19 was not a major problem in their community were significantly less likely to be vaccinated, while those with more favorable attitudes toward vaccines in general and public health strategies to decrease the impact of COVID-19 were significantly more likely to be vaccinated. Overall, barriers to vaccine uptake for the "Wait and See" cohort appear to be more practical, whereas barriers for the "Non-Acceptor" cohort seem to be more ideological. These findings will help target interventions to improve uptake of COVID-19 boosters and future novel vaccines.
Project description:Recent evidence suggests that living in a neighborhood with a greater percentage of older adults is associated with better individual health, including lower depression, better self-rated health, and a decreased risk of overall mortality. However, much of the work to date suffers from four limitations. First, none of the U.S.-based studies examine the association at the national level. Second, no studies have examined three important hypothesized mechanisms - neighborhood socioeconomic status and neighborhood social and physical characteristics - which are significantly correlated with both neighborhood age structure and health. Third, no U.S. study has longitudinally examined cognitive health trajectories. We build on this literature by examining nine years of nationally-representative data from the Health and Retirement Study (2002-2010) on men and women aged 51 and over linked with Census data to examine the relationship between the percentage of adults 65 and older in a neighborhood and individual cognitive health trajectories. Our results indicate that living in a neighborhood with a greater percentage of older adults is related to better individual cognition at baseline but we did not find any significant association with cognitive decline. We also explored potential mediators including neighborhood socioeconomic status, perceived neighborhood cohesion and perceived neighborhood physical disorder. We did not find evidence that neighborhood socioeconomic status explains this relationship; however, there is suggestive evidence that perceived cohesion and disorder may explain some of the association between age structure and cognition. Although more work is needed to identify the precise mechanisms, this work may suggest a potential contextual target for public health interventions to prevent cognitive impairment.
Project description:BackgroundPatients with acute heat illness present primarily to emergency departments (EDs), yet little is known regarding these visits.ObjectiveWe aimed to describe acute heat illness visits to U.S. EDs from 2006 through 2010 and identify factors associated with hospital admission or with death in the ED.MethodsWe extracted ED case-level data from the Nationwide Emergency Department Sample (NEDS) for 2006-2010, defining cases as ED visits from May through September with any heat illness diagnosis (ICD-9-CM 992.0-992.9). We correlated visit rates and temperature anomalies, analyzed demographics and ED disposition, identified risk factors for adverse outcomes, and examined ED case fatality rates (CFR).ResultsThere were 326,497 (95% CI: 308,372, 344,658) cases, with 287,875 (88.2%) treated and released, 38,392 (11.8%) admitted, and 230 (0.07%) died in the ED. Heat illness diagnoses were first-listed in 68%. 74.7% had heat exhaustion, 5.4% heat stroke. Visit rates were highly correlated with annual temperature anomalies (Pearson correlation coefficient 0.882, p = 0.005). Treat-and-release rates were highest for younger adults (26.2/100,000/year), whereas hospitalization and death-in-the-ED rates were highest for older adults (6.7 and 0.03/100,000/year, respectively); all rates were highest in rural areas. Heat stroke had an ED CFR of 99.4/10,000 (95% CI: 78.7, 120.1) visits and was diagnosed in 77.0% of deaths. Adjusted odds of hospital admission or death in the ED were higher among elders, males, urban and low-income residents, and those with chronic conditions.ConclusionsHeat illness presented to the ED frequently, with highest rates in rural areas. Case definitions should include all diagnoses. Visit rates were correlated with temperature anomalies. Heat stroke had a high ED CFR. Males, elders, and the chronically ill were at greatest risk of admission or death in the ED. Chronic disease burden exponentially increased this risk.
