RESUMEN
Background@#Prostate-specific antigen-based routine screening is not recommended for the general population due to conflicting results with mortality reduction. We aimed to develop a web-based decision aid (DA) for informed decision making for prostate cancer screening. @*Methods@#Using the International Patient Decision Aid Standards (IPDAS) development process model, we developed our DA based on patient and clinician interviews and multidisciplinary expert discussions. The prototype consisted of predicting individual prostate cancer risk and informed decision-making, including knowledge, risk and benefit, cost, personal value, and decision making. We conducted a pilot study on 101 healthy men, evaluating the effectiveness of DA by measuring knowledge, attitude, and intention to screen before and after using the DA, as well as decisional conflict and usefulness after using the DA. @*Results@#Of the 101 participants (median age 60 [50–69] years), 84% had not undergone screening for prostate cancer in the past two years. After using the DA, knowledge on prostate cancer screening increased (mean score [of 10] before versus after: 6.85 ± 1.03 versus 7.57 ± 1.25; P < 0.001), and intention to not screen increased from 27.7% to 51.5% (P < 0.001), but attitude toward screening did not change (P = 0.564). After use of the DA, 79 participants reported no decisional conflict, and the usefulness score was high (mean score [of 100] 77.35 ± 7.69), with 85% of participants reporting that the DA helped with decision making. @*Conclusion@#Our web-based DA yielded increased knowledge, decreased screening intention, and high perceived usefulness. These findings indicate potential clinical relevance, especially among younger individuals.
RESUMEN
Background@#The factors associated with sleep disorder are controversial. This study aimed to evaluate the prevalence of sleep disorder and the factors associated with sleep disorder among Korean adult cancer survivors. @*Methods@#In this cross-sectional study, we collected data on sleep problems as outcome variables, and sociodemographic and clinical information as predictor variables from cancer survivors at two university-affiliated hospitals. Sleep disorder was defined as “a difficulty in sleep initiation or sleep maintenance at least 3 times a week that started after a cancer diagnosis.” Multiple logistic regression analysis was performed with odds ratios (OR) and 95% confidence intervals (95% CI) to evaluate the factors associated with sleep disorder. @*Results@#The participants were 1,893 Korean cancer survivors (mean age, 58.1 years; females 68.0%). The prevalence of sleep disorder among male and female cancer survivors were 16.5% and 20.3%, respectively. An increase of age by 1-year was associated with a 1.04 (95% CI, 1.01–1.07; P=0.011) times higher risk of sleep disorder in males, while an inverse association was found in females. In female survivors, high fear of cancer recurrence (FCR), high anxiety, menopause, and high EuroQol Visual Analog Scale were associated with 1.45 (95% CI, 1.06–1.98; P=0.020), 1.78 (95% CI, 1.25–2.55; P=0.002), 1.70 (95% CI, 1.08–2.67; P=0.022), and 0.59 (95% CI, 0.43–0.82; P=0.002) times higher risk of sleep disorder, respectively. In male survivors, living with a spouse/or partner was associated with 57% (95% CI, 0.20–0.95; P=0.036) lower risk of sleep disorder. Analyses of cancer sites showed that the factors associated with sleep disorder varied across cancer sites. @*Conclusion@#One-fifth of adult cancer survivors had sleep disorder. Age, menopausal status, FCR, anxiety, living with a spouse or partner, and quality of life were independently associated with sleep disorder in Korean cancer survivors.
RESUMEN
Purpose@#The purpose of the study was to validate the Korean version of Cancer Survivors’ Unmet Needs (CaSUN) scale among non–small cell lung cancer survivors. @*Materials and Methods@#Participants were recruited from outpatient clinics at the Samsung Medical Center in Seoul, South Korea, from January to October 2020. Participants completed a survey questionnaire that included the CaSUN. Exploratory and confirmatory factor analysis and Pearson’s correlations were used to evaluate the reliability and validity of the Korean version of the CaSUN (CaSUN-K). We also tested known-group validity using an independent t test or ANOVA. @*Results@#In total, 949 provided informed consent and all of which completed the questionnaire. Among the 949 patients, 529 (55.7%) were male; the mean age and median time since the end of active treatment (standard deviation) was 63.4±8.8 years and the median was 18 months. Although the factor loadings were different from those for the original scale, the Cronbach’s alpha coefficients of the six domains in the CaSUN-K ranged from 0.68 to 0.95, indicating satisfactory internal consistency. In the CFA, the goodness-of-fit indices for the CaSUN-K were high. Moderate correlations demonstrated the convergent validity of CaSUN-K with the relevant questionnaire. More than 60% of the participants reported information-related unmet needs, and the CaSUN-K discriminated between the needs reported by the different subgroups that we analyzed. @*Conclusion@#The CaSUN-K is a reliable and valid measure for assessing the unmet needs in a cancer population, thus this tool help population to receive timely, targeted, and relevant care.
RESUMEN
Background@#This study aimed to examine the association between coffee or green tea consumption and ferritin or hemoglobin levels in premenopausal women. @*Methods@#We used the fifth Korea National Health and Nutrition Examination Survey (2010–2012), and a total of 4,322 individuals were surveyed. In women of reproductive age, average ferritin and hemoglobin levels were calculated according to coffee or green tea consumption. Covariates included in the analysis were demographic variables, such as age, body mass index, education, drinking, smoking, history of hypertension, history of diabetes diagnosis, physical activity, total energy intake, and daily iron intake. @*Results@#In 4,322 participants, the average hemoglobin level was 12.90±0.02 g/dL, and the average level of ferritin was 31.95±0.67 ng/mL. As a result of testing, correlation between ferritin and coffee intake and difference in ferritin levels according to coffee consumption was significant (P2 cups of coffee significantly affect ferritin levels in Korean premenopausal women.
RESUMEN
Background@#Since the introduction of heated tobacco products (HTPs) in Korea in 2017, their annual sales have increased. Several studies have investigated the perceptions of HTPs and smoking cessation behaviors. For the first time, In 2019, questions focused on HTP use were introduced in the Korea National Health and Nutrition Examination Survey (KNHNES). This study aimed to compare smoking cessation behaviors between HTP users and conventional cigarette smokers using KNHANES data. @*Methods@#Data of 947 current adult smokers from the 8th KNHNES (2019) were analyzed. Current smokers were divided into conventional cigarette (CC)–only, HTP-only, and dual-use groups. The general characteristics of the three groups were investigated. Differences in current intention to quit smoking and past attempts to quit smoking among the three groups were analyzed using multivariate logistic regression analysis by IBM SPSS ver. 25.0. @*Results@#HTP-only users demonstrated fewer future smoking cessation plans (adjusted odds ratio [AOR], 0.398; 95% confidence interval [CI], 0.195–0.813; P=0.012) and fewer smoking cessation attempts in the past year (AOR, 0.533; 95% CI, 0.298–0.954; P=0.034) than CC-only smokers. However, there was no significant difference between dual-use (CC+HTP) and CC-only smokers. @*Conclusion@#While dual-use and CC-only smokers showed similar smoking cessation behaviors, HTP-only users had fewer previous attempts to quit smoking and were less likely to be currently ready to quit smoking. These findings can be explained by a decrease in the need to quit smoking due to the convenience of HTP and the perception that HTPs are less harmful than CC.
RESUMEN
Background@#Hearing loss (HL) has been suggested to be associated with impaired microcirculation of the inner ear. This cross-sectional study aimed to evaluate an association between HL and serum lipid levels. @*Methods@#The study comprised 10,356 Korean adults who participated in the fifth Korea National Health and Nutrition Examination Survey (2010–2012). We defined HL as the average hearing thresholds exceeding 25 dB at predetermined frequency levels by pure tone audiometry. Serum lipid levels were measured using an enzymatic assay. The associations between lipid levels and HL were evaluated using a multiple logistic regression model after adjusting for covariates including age, sex, hypertension, diabetes, smoking status, alcohol, physical activity, educational level, household income, and noise exposure. Stratified analyses were performed to examine the effect of the covariates on the association between lipid levels and HL. @*Results@#The high-density lipoprotein cholesterol (HDL-C) level was inversely associated with high-frequency (HF)-HL, with an odds ratio (95% confidence interval) of 0.78 (0.64–0.96) for 1-mmol/L increase in the HDL-C level. Neither the triglyceride nor the low-density lipoprotein cholesterol level was associated with HF-HL. For low-frequency HL, association with any of the serum lipid components was absent. A stratified analysis showed that the inverse association between HDL-C levels and HF-HL was evident (P trend 0.05). @*Conclusion@#The HDL-C level has a linear inverse association with the risk of HF-HL. Given the known protective role of HDL-C against atherosclerotic changes, this finding seems to support the concept of impaired microcirculation in the inner ear as a mechanism for HF-HL.
