Prediction Rules Identify Which Young Adults Have Higher Rates of Heavy Episodic Drinking After Exposure to 12-Week Text Message Interventions.

BACKGROUND: An alcohol text message intervention recently demonstrated effects in reducing heavy episodic drinking (HED) days at the three month follow-up in young adults with a history of hazardous drinking. An important next step in understanding intervention effects involves identifying baseline participant characteristics that predict who will benefit from intervention exposure to support clinical decision-making and guide further intervention development. To identify baseline characteristics that predict HED, this exploratory study used a prediction rule ensemble (PRE). Compared to more complex decision-tree methods (e.g., random forest), PREs have comparable performance, while generating simpler rules that can directly identify subgroups that do or do not respond to intervention. METHODS: This secondary analysis examined data from 916 young adults who reported HED (68.5% female, mean age = 22.1, SD = 2.1), were enrolled in an alcohol text message randomized clinical trial and who completed baseline assessment and the three month follow-up. A PRE with ten fold cross-validation, which included 21 baseline variables representing sociodemographic characteristics (e.g., sex, age, race, ethnicity, college enrollment), alcohol consumption (frequency of alcohol consumption, quantity consumed on a typical drinking day, frequency of HED), impulsivity subscales (i.e., negative urgency, positive urgency, lack of premeditation, lack of perseverance, sensation seeking), readiness to change, perceived peer drinking and HED-related consequences, and intervention status were used to predict HED at the three month follow-up. RESULTS: The PRE identified 12 rules that predicted HED at three months (R2 = 0.23) using 7 baseline features. Only two cases (0.2%) were not classified by the 12 rules. The most important features for predicting three month HED included baseline alcohol consumption, negative urgency score, and perceived peer drinking. CONCLUSIONS: The rules provide interpretable decision-making tools that predict who has higher alcohol consumption following exposure to alcohol text message interventions using baseline participant characteristics (prior to intervention), which highlight the importance of interventions related to negative urgency and peer alcohol use.

A systematic review of factors associated with student use of campus food pantries: implications for addressing barriers and facilitating use.

BACKGROUND: While campus food pantries have been important safety net programs for alleviating food insecurity among college students, factors related to accessing these vital resources have not been fully researched and summarized. This study systematically synthesized peer-reviewed literature on the predictors, barriers to, and facilitators of using campus food pantries among college students. METHODS: A search was conducted on PubMed, CINAHL Complete, PsychInfo, PsycARTICLES, and ScienceDirect in April 2023. Included studies needed to be peer-reviewed, written in English, and focused on college or university students. Three authors independently screened all articles retrieved from the five databases based on titles, titles and abstracts, and a full article review. The Study Quality Assessment Tool from the National Heart, Lung, and Blood Institute was used to assess the risk of bias in the included cross-sectional studies. The risk of bias and quality of mixed methods or qualitative studies were assessed as well. RESULTS: Eight studies were included in the systematic review. Students likely to use a college food pantry were food-insecure, who most often identified as Asian, Hispanic/Latino, Filipino or Pacific Islander; were first-generation to college; international students; sophomores and juniors; had student loans; were living off-campus; and were without stable housing. Stigma was the most frequently mentioned barrier to using a food pantry. Participants mentioned facilitators such as convenient location and hours of operation, access to fresh produce and nutritious and safe foods, availability of a variety of foods, friendly and helpful service, social support, and awareness of a pantry through fellow students and other members of the university such as staff and faculty. CONCLUSIONS: Continued research must address students' systemic barriers to accessing food pantries. Campus food pantry leaders, university administrators, and policymakers need to work together to create cost-effective and sustainable solutions that will alleviate the stigma and burden of food-insecure students and provide them with safe, nutritious, and culturally acceptable foods.

Reliability of a frequency method for assessing vegetable intake using photos among college students: a smart phone approach.

OBJECTIVE: To measure the interrater reliability of assessing the frequency of vegetable intake using mobile photos and descriptions. DESIGN: Repeated measures design. SETTING: A Midwestern university. PARTICIPANTS: Undergraduate students (N = 165). MEASURABLE OUTCOME/ANALYSIS: Number of times each of these vegetable subgroups were consumed daily: dark green vegetables, beans and peas, starchy vegetables, and other vegetables. Analysis: Two raters independently coded meals using mobile photos and descriptions of meals. Cohen κ was calculated to determine interrater reliability. RESULTS: A value of κ = 0.9 (p < .001) was obtained, indicating an almost perfect agreement between the two raters. Nearly 92% of participants complied with providing photos along with descriptions of their meals. CONCLUSIONS AND IMPLICATIONS: A frequency method using mobile photos and descriptions of meals is a reliable strategy to assess vegetable consumption. This frequency method can improve data quality, reduce participant burden, and minimize recall bias in college nutrition programs.

Mexican Parents' Beliefs About Drinking Plain Water in Front of Their Preschoolers.

Because children learn habits from observing their parents, we assessed the top-of-the-mind beliefs held by parents about "drinking plain water in front of their preschool child during lunch one day this coming weekend." We recruited a convenience sample of 34 Mexican parents from daycares in Guadalajara and conducted a content analysis. Main advantage identified was getting healthier, followed by being a good example for the child. Few parents identified disadvantages. Most reported to have at least one approver within their families. The most frequent facilitator was "having it," while "not having it" was the main barrier.

Where there are fumes, there may be lung cancer: a systematic review on the association between exposure to cooking fumes and the risk of lung cancer in never-smokers.

PURPOSE: Lung cancer in never-smokers (LCINS) is the seventh leading cause of cancer, and exposure to cooking fumes has recently emerged as a potential risk factor. This systematic review is the first to summarize and evaluate the relationship between exposure to cooking fumes and the risk of LCINS. METHODS: This study conducted an online literature search of PubMed, CINAHL, and PsychInfo databases. Inclusion criteria were original research articles published in English, that assessed the relationship between exposure to cooking fumes and the risk of lung cancer between 1 January 2012 and 6 December 2022, and that included never-smokers. RESULTS: Thirteen case-control studies and three prospective cohort studies, focusing mostly on women with LCINS, met the inclusion criteria. Seven case-control studies reported an association between exposure to cooking oil fumes and an increased risk of LCINS. Two case-control studies found that using a fume extractor was associated with a decreased risk of LCINS. In other case-control studies, coal use was linked to an increased risk of LCINS, and participants who did not use a ventilator in their kitchens had a higher risk for LCINS. Poor ventilation [Adjusted Hazard Ratio (AHR) = 1.49; 95% CI: 1.15, 1.95] and poor ventilation in combination with coal use (AHR = 2.03; 95% CI: 1.35, 3.05) were associated with an increased risk for LCINS in one prospective cohort study. CONCLUSION: The evidence reviewed underscores the need to develop culturally-tailored interventions that improve access to affordable and clean fuel through engaging relevant stakeholders.

Trends in lip, oral cavity, and pharyngeal cancer mortality in the United States, 1999-2019.

BACKGROUND: Changes in the epidemiology of lip, oral cavity, and pharyngeal (LOCP) cancers have been reported in the United States. This study aimed to examine recent trends in LOCP cancer mortality in the United States from 1999 to 2019. METHODS: National mortality data were extracted from CDC WONDER, 1999-2019. International Classification of Diseases Codes, 10th Revision-C00-C14, were used to identify decedents of malignant neoplasms of the lip, oral cavity, and pharynx. LOCP cancer mortality trends were assessed by fitting a Joinpoint regression model overall, and by race/ethnicity, sex, age, and US Census Region. Annual Percentage Changes (APC) were derived to estimate variations in mortality trends over time. RESULTS: The age-adjusted mortality rate (AAMR) for LOCP cancers was 2.5 per 100 000 (95% CI: 2.5-2.5), equivalent to 180 532 deaths during 1999-2019. Overall mortality trends have stabilized since 2009 (APC = 0.3; 95% CI: -0.1, 0.7), but an examination by subtype revealed rising mortality trends from cancers of the lip and oral cavity (APC = 1.2; 95% CI: 0.7, 1.6) and pharynx (APC = 3.2; 95% CI: 1.7, 4.8), and declining trends in malignancies of other and ill-defined areas of the lip, oral cavity, and pharynx (APC = -2.7; 95% CI: -3.4, -2.0). Trend variations were also noted by sex, age, US Census Region, and race/ethnicity. CONCLUSIONS: There are differential trends in mortality from LOCP cancers in the United States. Investigating the biological, individual, and contextual factors related to LOCP cancers would guide effective public health intervention efforts.

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.

Digital interventions for promoting sun protection and skin self-examination behaviors: A systematic review.

The skin cancer incidence rate has been rising, and digital health interventions can promote skin cancer prevention and detection behaviors. A systematic review was conducted to investigate the outcomes of digital interventions that promote sun protection and skin self-examination (SSE). This review examined studies that utilized randomized controlled designs or quasi-experiments, included outcomes related to sun safety or SSE, employed at least one digital platform, and were published in English from January 2000 to October 2020. A total of 62 studies were included in the review. Digital modalities included web-based (e.g., websites) alone (n = 29), mobile-based (e.g., mobile apps) alone (n = 12), game-based (n = 1), emails or text messages alone (n = 8), videos alone (n = 6), social media (n = 3), both text messages and mobile apps (n = 2), or both text messages and video (n = 1). Most studies (n = 44) only evaluated sun protection-related outcomes, seven studies assessed SSE outcomes only, nine studies examined both, and two assessed other related outcomes. Digital interventions are effective compared to non-intervention control conditions in promoting sun safety or SSE. Almost all studies found digital interventions to be equally or more effective compared to non-digital interventions. This review suggests that although the digital interventions varied, they showed promising effects on improving sun protection or SSE outcomes. Future research should include more sophisticated phase-based and rigorous longitudinal research designs, additional investigation of social media and other newer technologies, as well as more detailed reporting of methods and results.

Underdiagnosis of iron deficiency anemia among patients with colorectal cancer: an examination of electronic medical records.

BACKGROUND: Timely diagnosis and management of iron deficiency anemia (IDA) in colorectal cancer (CRC) patients improves overall quality of life and survival. This study assessed the proportion of CRC patients who were formally diagnosed with IDA and factors that predict a formal diagnosis of IDA and receiving iron therapy. METHODS: We retrieved electronic medical records (EMRs) of CRC patients from a large comprehensive cancer center in the Northeastern part of the United States (n = 499). We abstracted sociodemographic characteristics, relevant laboratory results, IDA diagnosis, and iron supplementation from the EMRs. We assessed relationships between participant characteristics, a diagnosis of IDA and receiving iron therapy through adjusted logistic regressions. RESULTS: IDA was formally diagnosed in 26 (5.2%) individuals judged by EMR documentation. Only 153 (30.7%) participants had iron laboratory results available. Among the 153 patients with iron panel data available, 113 (73.9%) had iron deficiency. Seventy-six had absolute iron deficiency as shown by ferritin levels below 100 ng/mL and iron saturation less than 20% and 37 had functional iron deficiency as shown by ferritin levels between 100 and 500 ng/mL and iron saturation less than 20%. 12% of all patients had documentation of iron therapy receipt. A formal diagnosis of IDA was not associated with any of the covariates. CONCLUSIONS: Iron deficiency anemia is under-diagnosed among CRC patients and most likely under-documented in clinical notes. Rates of iron repletion are low, suggesting that many patients with IDA are untreated. Future research should explore provider-level and other strategies for improving assessment and diagnosis of IDA among CRC patients.

Cancer Survivors' Emotional Well-being: Roles of Internet Information Seeking, Patient-centered Communication, and Social Support.

Cancer survivors' emotional well-being is an integral part of their overall health and may influence their recovery and survival. The current study used the 2018 Health Information National Trends Survey (HINTS) 5 Cycle 2 (N = 593) to evaluate the determinants of cancer survivors' emotional well-being. Internet cancer information seeking, social support, patient-centered communication, cancer beliefs, and self-efficacy to take care of one's health were examined as factors to be associated with cancer survivors' emotional well-being using structural equation modeling. Social support, cancer beliefs, and self-efficacy to take care of one's health were found to be significantly associated with emotional well-being among cancer survivors. Cancer beliefs mediated the associations of cancer information seeking using the Internet, social support, and patient-centered communication with cancer survivors' emotional well-being while health self-efficacy mediated the associations of social support and patient-centered communication with cancer survivors' emotional well-being. It is important for health practitioners to focus on improving social support, self-efficacy for managing health, and cancer-related beliefs in order to enhance the emotional well-being of cancer survivors.

Cost, reach, and representativeness of recruitment efforts for an online skin cancer risk reduction intervention trial for young adults.

Despite its increasing use, few studies have reported on demographic representativeness and costs of research recruitment via social media. It was hypothesized that cost, reach, enrollment, and demographic representativeness would differ by social media recruitment approach. Participants were 18-25 year-olds at moderate to high risk of skin cancer based on phenotypic and behavioral characteristics. Paid Instagram, Facebook, and Twitter ads, unpaid social media posts by study staff, and unpaid referrals were used to recruit participants. Demographic and other characteristics of the sample were compared with the 2015 National Health Interview Survey (NHIS) sample. Analyses demonstrated significant differences among recruitment approaches regarding cost efficiency, study participation, and representativeness. Costs were compared across 4,274 individuals who completed eligibility screeners over a 7-month period from: Instagram, 44.6% (of the sample) = 1,907, $9 (per individual screened); Facebook, 31.5% = 1,345, $8; Twitter, 1% = 42, $178; unpaid posts by study staff, 10.6% and referred, 6.5%, $1. The lowest rates of study enrollment among individuals screened was for Twitter. Most demographic and skin cancer risk factors of study participants differed from those of the 2015 NHIS sample and across social media recruitment approaches. Considering recruitment costs and number of participants enrolled, Facebook and Instagram appeared to be the most useful approaches for recruiting 18-25 year-olds. Findings suggest that project budget, target population and representativeness, and participation goals should inform selection and/or combination of existing and emerging online recruitment approaches.

Correlates of sun protection behaviors among melanoma survivors.

BACKGROUND: The study objective was to assess potential correlates of sun protection behaviors among melanoma survivors. METHODS: Participants were 441 melanoma survivors recruited from three health centers and a state cancer registry in the United States. Sun protection behaviors (sunscreen, shade, protective shirts, and hats) were assessed through an online survey, as were potential correlates (demographic, melanoma risk, knowledge and beliefs, psychological and social influence factors). Hierarchical multiple regression analyses were conducted. RESULTS: Correlates of sun protection behaviors included education, skin cancer risk factors, melanoma knowledge and beliefs, melanoma worry and distress, physician recommendation for sun protection, injunctive norms, and pro-protection beliefs (e.g., perceived barriers, self-efficacy). CONCLUSIONS: Future efforts to improve sun safety among melanoma survivors may benefit from targeting individuals with lower education levels, and addressing sun protection social influence, barriers, and self-efficacy.

Association Between State Indoor Tanning Legislation and Google Search Trends Data in the United States From 2006 to 2019: Time-Series Analysis.

BACKGROUND: Exposure to ultraviolet radiation from the sun or indoor tanning is the cause of most skin cancers. Although indoor tanning has decreased in recent years, it remains most common among adolescents and young adults, whose skin is particularly vulnerable to long-term damage. US states have adopted several types of legislation to attempt to minimize indoor tanning among minors: a ban on indoor tanning among all minors, a partial minor ban by age (eg, <14 years), or the requirement of parental consent or accompaniment for tanning. Currently, only 6 US states have no indoor tanning legislation for minors. OBJECTIVE: This study investigated whether internet searches (as an indicator of interest) related to indoor tanning varied across US states by the type of indoor tanning legislation, using data from Google Trends from 2006 to 2019. METHODS: We conducted a time-series analysis of Google Trends data on indoor tanning from 2006 to 2019 by US state. Time-series linear regression models were generated to assess the Google Trends data over time by the type of indoor tanning legislation. RESULTS: We found that indoor tanning search rates decreased significantly for all 50 states and the District of Columbia over time (P<.01). The searches peaked in 2012 when indoor tanning received marked attention (eg, indoor tanning was banned for all minors by the first state-California). The reduction in search rates was more marked for states with a complete ban among minors compared to those with less restrictive types of legislation. CONCLUSIONS: Our findings are consistent with those of other studies on the association between indoor tanning regulations and attitudinal and behavioral trends related to indoor tanning. The main limitation of the study is that raw search data were not available for more precise analysis. With changes in interest and norms, indoor tanning and skin cancer risk among young people may change. Future studies should continue to determine the impact of such public health policies in order to inform policy efforts and minimize risks to public health.

Breastfeeding is Possible: A Systematic Review on the Feasibility and Challenges of Breastfeeding Among Breast Cancer Survivors of Reproductive Age.

BACKGROUND: Breastfeeding is the biologically normative mode of feeding human infants, and reduces the risk of breast cancer for mothers. This systematic review assesses engagement in breastfeeding and the factors associated with breastfeeding among breast cancer survivors. METHODS: An online literature search was performed using the PubMed, Embase, CINAHL, PsychInfo, and Web of Science databases. Inclusion criteria were original research articles written in English, published in peer-reviewed journals from 1 January 1990 to 25 November 2019, and included data on breast cancer survivors who attempted breastfeeding. RESULTS: Thirteen studies were included in the systematic review. Between 7.7 and 90.9% of women attempted breastfeeding. Breastfeeding among participants varied from a few weeks to approximately 2 years. Common factors leading to breastfeeding were use of the contralateral breast, support from others, lactation counseling and advice from an International Board-Certified Lactation Consultant, being motivated to breastfeed, frequent feedings, and use of galactagogues. Common barriers were medical counseling against breastfeeding, insufficient milk production, lack of support, refusal of the infant to breastfeed from the treated breast, and being tired from relying on one breast. CONCLUSIONS: Breastfeeding from the unaffected breast is feasible for some breast cancer survivors. Successful breastfeeding may require multilevel support and expert advice.

Associations of Social Media Use, Patient-centered Communication, and Knowledge with Perceived Human Papillomavirus Vaccine Effectiveness.

Objectives: Given the effectiveness of human papillomavirus (HPV) vaccination in preventing cervical cancer and other diseases, as well as the low rates of HPV vaccination in the United States, it is important to examine the determinants of perceived HPV vaccine effectiveness. In this study, we examined the associations between potential factors associated with perceived HPV vaccine effectiveness. Methods: We utilized data (N = 718) from the nationally representative 2017 Health Information National Trends Survey (HINTS). We examined the associations of health-related social media use, patient-centered communication, and HPV knowledge with perceived HPV vaccine effectiveness in preventing cervical cancer. We reported descriptive statistics, and conducted bivariable analyses, multivariable analysis, and mediation analyses. Results: Perceived HPV vaccine effectiveness was associated with sex, age, education, health-related social media use, and HPV knowledge. Additionally, HPV knowledge mediated the associations of health-related social media use and patient-centered communication with perceived HPV vaccine effectiveness. Conclusions: Improving health-related information from social media, patient-centered communication, and HPV knowledge may increase perceived HPV vaccine effectiveness and ultimately, vaccine adoption.

A Randomized mHealth Trial to Promote Vegetable Intake Through Counting and Goal Setting.

OBJECTIVE: To determine if counting and goal setting can increase red/orange vegetable intake. DESIGN: Pre-posttest experimental. SETTING: Midwestern university. PARTICIPANTS: Undergraduate students (n = 165). INTERVENTION: Those in the intervention group (n = 85) were asked to count the number of times they ate red/orange vegetables and set a goal to eat 1 more time. MAIN OUTCOME MEASURE: An estimate (number of times/d) of vegetable intake based on an independent review of uploaded photographs and descriptions of meals from smartphones. ANALYSIS: Generalized estimating equations. RESULTS: For the intervention group, mean frequency intake increased from 0.9 times/d on Monday to 1.6 times/d on Tuesday and to 1.3 times/d on Wednesday, whereas mean intakes for the control group were 1.0, 0.8, and 0.8 times/d, respectively. There were significant group × time interactions for Tuesday (ß = 0.8; P < 0.001) and Wednesday (ß = 0.5; P = 0.006). CONCLUSIONS AND IMPLICATIONS: A mobile method that helped people count their daily red/orange vegetable intake and set a goal appeared to increase consumption. This finding suggests that nutrition education programs that provide people with easy ways to track specific dietary behaviors might be effective at helping them attain goals.

Prevalence and correlates of skin self-examination behaviors among melanoma survivors: a systematic review.

Melanoma is the most common cause of skin cancer deaths, and individuals who have had melanoma have an increased risk of developing new melanomas. Doing regular self-examinations of skin enables one to detect thinner melanomas earlier when the disease is more treatable. The aim of this systematic review is to characterize and evaluate the existing literature on the prevalence and correlates of skin self-examination (SSE) behaviors among adult melanoma survivors in the USA and Canada. A computerized literature search was performed using PubMed, Google Scholar, and ScienceDirect. The inclusion criteria for the studies were: (a) reported results for adult melanoma survivors in the USA or Canada, (b) papers described empirical research, (c) assessed SSE and related behaviors, and (d) papers were published in a peer-reviewed journal in the past 20 years. Key phrases such as "skin self-examination/SSE in melanoma survivors in the United States" and "correlates of skin self-examination/SSE" were used. Based on the inclusion criteria, 30 studies were included in the systematic review. SSE prevalence varied depending on how SSE was defined. Demographics and factors (gender, education level, patient characteristics, partner assistance, and physician support) associated with SSE were identified. Findings of this review show evidence for the need to have a consistent way to assess SSE and suggest different types of correlates on which to focus in order to promote SSE and reduce the risk of melanoma recurrence in survivors. This systematic review and its protocol have been registered in the international database of prospectively registered systematic reviews in health and social care (PROSPERO; ID: 148878).

Are Eating Habits Associated with Adequate Sleep among High School Students?

BACKGROUND: Sleep deprivation adversely impacts cognitive performance. A nutritious diet is one strategy that can prevent sleep deprivation and its adverse effects. However, few data exist regarding the influence of diet on sleep duration among adolescents. Hence, it is important to assess whether dietary habits are linked to adequate sleep among adolescents. METHODS: The 2013 Youth Risk Behavior Survey data were used in the analysis. Nationally representative samples of adolescents were obtained using a 3-stage cluster design. Selected survey items included number of hours slept on a school night, fruit and vegetable intake, soda and milk intake, breakfast consumption, and demographic variables. Data were analyzed with SAS 9.4 using a logistic regression model. RESULTS: Holding other variables constant, an increase in total daily consumption of vegetables, milk, and breakfast increased the odds of sleeping ≥8 hours among participants (p < .01). An increase in daily soda intake decreased the odds of sleeping ≥8 hours among participants (p < .01). Separate logistic models for males and females yielded similar findings (p < .01). CONCLUSIONS: Promoting healthy eating habits such as intake of vegetables, milk, and breakfast consumption among adolescents may increase their likelihood of getting adequate sleep.
