How Much Is Too Much? Estimating Effective Price-Hikes to Affect Smoking Behavior in Vietnam.

INTRODUCTION: Raising the price of cigarettes is one of the most effective strategies to reduce cigarette smoking. The Vietnamese government is working toward the tobacco control goal of a 10% reduction in smoking prevalence by 2020. However, cigarette prices in Vietnam have not increased in the last two decades. The aim of this study was to estimate what cigarette prices would make smokers attempt to quit smoking, and to identify predictors of the price to quit and the intention to quit. METHODS: A cross-sectional survey was conducted with 822 male current smokers in Da Nang, Vietnam. A structured questionnaire was adapted from the International Tobacco Control project survey. Bayesian quantile regression was applied to predict factors associated with expected cigarette price. RESULTS: Fifty-six percent of smokers suggested a price to quit. Their median suggested price to quit per pack, 62 000 VND (2.8 USD), was 2.8 times higher than the actual current price, 22 000 VND (1.01 USD). Suggesting a lower price to quit was significantly associated with awareness of warning labels and smoke-free policies. In contrast, being a heavy smoker was significantly associated with a higher suggested price to quit across all quantiles. CONCLUSIONS: There may be sufficient room to increase cigarette prices in Vietnam. The price to quit is associated with various factors, including non-pricing policies. IMPLICATIONS: Evidence suggests that a steep increase in cigarette prices, setting a high minimum tax, and introducing a large specific tax, which are policy-induced price increases that can raise prices substantially in Vietnam, are preferable strategies. In addition to increasing price and taxes, the government should also strengthen non-pricing policies.

The prevalence trend of metabolic syndrome and its components and risk factors in Korean adults: results from the Korean National Health and Nutrition Examination Survey 2008-2013.

BACKGROUND: Abnormalities in the clinical markers of metabolic syndrome (MS) are associated with the development of cardiovascular disease, type 2 diabetes mellitus, and some cancers. MS prevalence in Korea increased between the mid-1990s and mid-2000s; however, no data on the recent trends of MS prevalence are available. Thus, we aimed to investigate the prevalence of MS, the five components of MS, and the related risk factors in Korean adults by using recent data. METHODS: Data from the Korean National Health and Nutrition Examination Survey conducted between 2008 and 2013 were used. The revised National Cholesterol Education Program criteria were used for defining MS. A multivariate logistic regression analyses was used to estimate the relationship between the related risk factors including behaviors, dietary factors, and the prevalence of MS. RESULTS: A total of 34,587 men and women were included in the analysis. Age-adjusted prevalence of MS in 2013 was 28.9% without a significant increasing or decreasing trend between 2008 and 2013. Among the five components of MS, abdominal obesity decreased in both men and women (annual percent change: -2.0 and -2.5%, respectively), the decrease being significant only in women, whereas blood pressure and blood glucose significantly increased in men (+1.9 and +2.7%, respectively). Age and obesity (odds ratio = 6.7, 95% confidence interval = 5.9-7.5 for body mass index ≥25 kg/m2 vs. body mass index <25 kg/m2) were associated with increased MS risk in both men and women. Smoking and alcohol drinking were significantly associated with increased MS risk in men, and association between MS and vitamin D deficiency was at the edge of statistical significance. Higher education and income level were significantly associated with decreased MS risk in women. During this period, smoking rate and physical activity, sodium intake, and serum vitamin D level significantly decreased. Education level, calorie intake, and intake of carbohydrate, fat, protein and calcium significantly increased. CONCLUSION: Several factors contribute to the stable MS prevalence-on the one hand, increased prevalence of high blood sugar, high blood pressure, calorie intake, and physical inactivity, and on the other hand, decreased prevalence of abdominal obesity and smoking. Lifestyle interventions to prevent and control non-communicable diseases should be implemented at the national level to reduce the burden of MS.

Validation of the Disaster Adaptation and Resilience Scale for Vulnerable Communities in Vietnam's Coastal Regions.

OBJECTIVES: This study validated the Vietnamese version of the Disaster Adaptation and Resilience Scale (DARS) for use in vulnerable communities in Vietnam. METHODS: This was a cross-sectional study involving 595 adults from 2 identified communities. The original DARS assessment tool was translated, and the validity and reliability of the Vietnamese version of DARS (V-DARS) were assessed. The internal consistency of the overall scale and its subscales was evaluated using Cronbach's alpha and McDonald's omega reliability coefficients. Confirmatory factor analysis (CFA) was employed to evaluate its construct validity, building upon the factor structure identified in exploratory factor analysis (EFA). Construct validity was assessed based on convergent and discriminant validity. RESULTS: Following the established criteria for EFA, 8 items were removed, resulting in a refined V-DARS structure comprising 35 items distributed across 5 distinct factors. Both alpha and omega reliability coefficients indicated strong internal consistency for the overall scale (α=0.963, ω=0.963) and for each of the 5 sub-scales (all>0.80). The CFA model also retained the 5-factor structure with 35 items. The model fit indices showed acceptable values (RMSEA: 0.072; CFI: 0.912; TLI: 0.904; chi-square test: <0.01). Additionally, the convergent and discriminant validity of the V-DARS were deemed appropriate and satisfactory for explaining the measurement structure. CONCLUSIONS: Our findings suggest that the V-DARS is a valid and reliable scale for use within vulnerable communities in Vietnam to assess adaptive responses to natural disasters. It may also be considered for use in other populations.

Validation of the COmprehensive Score for Financial Toxicity (COST) in Vietnamese patients with cancer.

INTRODUCTION: The COmprehensive Score for Financial Toxicity (COST) has proven to be a reliable tool for quantifying the impact of financial toxicity (FT) in patients with cancer in clinical and public health settings. However, the COST has not yet been validated in Vietnam. Therefore, we aimed to evaluate its reliability and validity among Vietnamese patients with cancer. METHODS: A cross-sectional study was conducted in a sample of 300 patients with cancer aged 27-95 years (mean: 58.5±11.2) in a tertiary hospital. The COST was translated into Vietnamese and English and adjusted to suit the local culture. Reliability was evaluated using Cronbach's alpha and McDonald's omega coefficients. The construct and convergent validities were also assessed. RESULTS: The COST demonstrated good internal consistency and reliability (Cronbach's alpha = 0.913; McDonald's omega = 0.915). The exploratory factor analysis revealed two factors that explained 64.9% of the variance. The adjusted fit indices indicated a good fit of the model (χ2 (39) = 67.78, p = 0.003; standardized root mean squared residual = 0.042; Tucker-Lewis index = 0.971; comparative fit index = 0.979; root mean square error of approximation = 0.061, 90% confidence interval = 0.035-0084). Higher COST scores were significantly correlated with higher health-related quality of life (EQ-5D-5L utility score: r = 0.21, p = 0.002; EQ VAS: r = 0.28, p < 0.001). Multivariate quantile regression analysis revealed that female sex, rural residence, and unstable job/unemployment were associated with lower COST scores. There was no statistically significant difference in other factors, including clinical factors (types of cancer, staging, and treatment modalities). CONCLUSIONS: The COST is reliable and valid, making it suitable for assessing FT severity in Vietnamese patients with cancer.

Willingness to Pay for a Quality-Adjusted Life Year among Gastrointestinal Cancer Patients at a Tertiary Hospital of Vietnam, 2022.

BACKGROUND: Gastrointestinal (GI) cancer burden in Asia is increasing, and Vietnam is no exception. Assessing the affordability of achieving a quality-adjusted life year (QALY) in gastrointestinal cancer patients Vietnam, as well as identifying predictors of willingness to pay (WTP) per QALY, is crucial to decision-making around medical intervention prioritization and performing medical technology assessments for these cancers. OBJECTIVES: Our study aimed to estimate WTP/QALY gained and associated factors among patients diagnosed with GI cancer at a tertiary hospital in Hue, Vietnam. METHODS: A cross-sectional descriptive study, using contingent valuation methodology was conducted among 231 patients at tertiary hospital in 2022. A double limited dichotomous choice and the EQ-5D-5L were utilised to estimate WTP and QALY, respectively. Quantile regression was applied to determine predictors of WTP/QALY. RESULTS: The mean and median maximum WTP/QALY gained among GI patients was $15,165.6 (42,239.6) and $4,365.6 (IQR: 1,586.5-14,552.0), respectively, which was equal to 3.68 times the 2022 gross domestic product (GDP) per capita in Vietnam.  Additionally, cancer severity was found to have a significant impact  on WTP per QALY gained, with a higher amount identified among patients with earlier stages of GI cancer. Furthermore, living in an urban dwelling and patients' treatment modalities were significantly associated with WTP/QALY. CONCLUSION: Evidence from our study can be used to inform how decision-makers in Vietnam to determine the cost-effectiveness of GI cancer interventions.

Beyond Medical Bills: High Prevalence of Financial Toxicity and Diverse Management Strategies Among Vietnamese Patients with Cancer.

Objectives: This study was conducted to measure financial toxicity (FT) among patients with cancer in Vietnam using the COmprehensive Score for financial Toxicity (COST) and to describe the cost management strategies employed by these patients. Methods: This comprehensive cross-sectional study enrolled 634 patients from 2 specialized oncology hospitals in Vietnam. Using COST cutoff scores, FT was classified as none/mild (≥26), moderate (14-25), or severe (≤13). Cost management strategies, or coping mechanisms, were classified into 4 groups: lifestyle changes, financial resource strategies, treatment modifications, and support seeking. Results: The prevalence of FT was 91.8%, with 51.7% of participants demonstrating severe and 40.1% exhibiting moderate FT. Severe FT was significantly associated with female sex, low education level, unstable employment, low household economic status, and advanced cancer stage. The most common coping strategies were as follows: among lifestyle changes, reducing spending on basic items and leisure activities (78.7%) and cutting back on essential household expenses (66.4%); among financial resource strategies, borrowing money from relatives or friends (49.1%) and withdrawing funds from retirement or savings accounts (32.1%); within treatment modifications, switching treatment facilities or doctors due to cost concerns (9.3%); and within support seeking, obtaining help from welfare or community organizations (18.8%). All strategies were significantly more likely to be used by patients with severe FT. Conclusions: FT was highly prevalent among patients with cancer. Most patients relied on lifestyle adjustments and coping strategies, underscoring the need for improved financial support systems to alleviate the economic burden associated with cancer care.

Assessing the knowledge and practice toward food safety: An investigation of food selection and processing among primary food caregivers in a town of Ha Tinh province, Vietnam.

The food selection and processing stage are important stages to prevent food poisoning. A good level of knowledge and practice regarding food selection and processing among people who are responsible for the family meals are important. In this study, we aimed to investigate the knowledge and practice of primary food caregivers regarding food poisoning prevention in food selection and processing and identify the factors that influence these outcomes. The current study applied a cross-sectional study to investigate 422 primary food caregivers in urban areas in Vietnam. Data were collected using a structured questionnaire, and knowledge and practice were assessed based on pre-defined criteria. The data were analyzed using descriptive statistics, chi-square test, and logistic regression. Our study found that 78.9% of people had good knowledge regarding food poisoning prevention in food selection and processing. Furthermore, 84.4% of people had correct practice in this regard. Our study also revealed that household income level and educational level were associated with knowledge and practice, respectively. The proportion of correct practice was higher in the group with good knowledge (90.4%) compared to the remaining group (61.8%). The results indicated that the proportion of good knowledge and practice were high among food caregivers, but further efforts are needed to improve the knowledge and practice of food caregivers with lower household income and educational levels. The findings also emphasize the importance of communication campaigns to enhance knowledge related to food poisoning prevention.

Mental health and its determinants among adolescents living in families with separated or divorced parents in an urban area of Vietnam.

BACKGROUND: We assessed the prevalence of stress, anxiety, and depression among adolescents living in families with separated or divorced parents in Hue City, Vietnam and identified factors associated with these conditions. METHODS: This cross-sectional study enrolled 309 adolescents, aged 12 to 17 years, living in families with separated or divorced parents in Hue City, Vietnam. The depression anxiety stress scale-21 (DASS-21) was used to measure stress, anxiety, and depression. Predictors of overall and individual mental health problems were identified using ordered and binary logistic regression, respectively. RESULTS: The DASS-21 scale revealed a 49.2% prevalence of stress, while anxiety and depression had s prevalence rates of 61.5%. Among participants, 42.4% experienced all 3 mental health issues. Several factors were identified as significant predictors of mental health problems, including poor to average economic status (adjusted odds ratio [aOR], 2.00; 95% confidence interval [CI], 1.21-3.31; p=0.007); being in high school (aOR, 5.02; 95% CI, 2.93-8.60; p<0.001); maternal occupation of teacher, healthcare professional, or official (aOR, 2.39; 95% CI, 1.13-5.03; p=0.022); longer duration of family separation or divorce (aOR, 1.24; 95% CI, 1.05-1.45; p=0.009); living with one's mother (aOR, 1.69; 95% CI, 1.03-2.76; p=0.04); alcohol consumption (aOR, 1.70; 95% CI, 0.99-2.92; p=0.050); and being bullied (aOR, 5.33; 95% CI, 1.10-25.69; p=0.037). Most of these factors were associated with stress, anxiety, and depression. Additionally, smoking was associated with stress. CONCLUSION: Adolescents with separated or divorced parents were at increased risk of stress, anxiety, and depression. The findings of this study provide important implications for prevention programs.

Sleep Quality and Poor Sleep-related Factors Among Healthcare Workers During the COVID-19 Pandemic in Vietnam.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has increased the workload of healthcare workers (HCWs), impacting their health. This study aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and identify factors associated with poor sleep among HCWs in Vietnam during the COVID-19 pandemic. METHODS: In this cross-sectional study, 1000 frontline HCWs were recruited from various healthcare facilities in Vietnam between October 2021 and November 2021. Data were collected using a 3-part self-administered questionnaire, which covered demographics, sleep quality, and factors related to poor sleep. Poor sleep quality was defined as a total PSQI score of 5 or higher. RESULTS: Participants' mean age was 33.20±6.81 years (range, 20.0-61.0), and 63.0% were women. The median work experience was 8.54±6.30 years. Approximately 6.3% had chronic comorbidities, such as hypertension and diabetes mellitus. About 59.5% were directly responsible for patient care and treatment, while 7.1% worked in tracing and sampling. A total of 73.8% reported poor sleep quality. Multivariate logistic regression revealed significant associations between poor sleep quality and the presence of chronic comorbidities (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.17 to 5.24), being a frontline HCW directly involved in patient care and treatment (OR, 1.59; 95% CI, 1.16 to 2.16), increased working hours (OR, 1.84; 95% CI,1.37 to 2.48), and a higher frequency of encountering critically ill and dying patients (OR, 1.42; 95% CI, 1.03 to 1.95). CONCLUSIONS: The high prevalence of poor sleep among HCWs in Vietnam during the COVID-19 pandemic was similar to that in other countries. Working conditions should be adjusted to improve sleep quality among this population.

Self-control as an important factor affecting the online learning readiness of Vietnamese medical and health students during the COVID-19 pandemic: a network analysis.

PURPOSE: The current study aimed to use network analysis to investigate medical and health students' readiness for online learning during the coronavirus disease 2019 (COVID-19) pandemic at the University of Medicine and Pharmacy, Hue University. METHODS: A questionnaire survey on the students' readiness for online learning was performed using a Google Form from May 13 to June 22, 2021. In total, 1,377 completed responses were eligible for analysis out of 1,411 participants. The network structure was estimated for readiness scales with 6 factors: computer skills, internet skills, online communication, motivation, self-control, and self-learning. Data were fitted using a Gaussian graphical model with the extended Bayesian information criterion. RESULTS: In 1,377 students, a network structure was identified with 6 nodes and no isolated nodes. The top 3 partial correlations were similar in networks for the overall sample and subgroups of gender and grade levels. The self-control node was the strongest for the connection to others, with the highest nodal strength. The change of nodal strength was greatest in online communication for both gender and grade levels. The correlation stability coefficient for nodal strength was achieved for all networks. CONCLUSION: These findings indicated that self-control was the most important factor in students' readiness network structures for online learning. Therefore, self-control needs to be encouraged during online learning to improve the effectiveness of achieving online learning outcomes for students.

Network analysis of psychological factors related to academic pressure faced by medical students in the central and highland regions of Vietnam.

Medical students experience extensive pressure during their undergraduate courses. Given the complex associations between psychological factors in association with academic pressure. We investigated the study with objectives: To examine psychological factors related to academic pressure by analysing interactions between 'study motivation', 'study environment', 'study conditions', 'teacher quality', 'training programme', 'management system', 'evaluation', and 'extracurricular activities' using a network analysis approach. A total of 878 medical students majoring in general medicine from the first, third, and fifth years of a six-year course at the largest medical university in central and highland regions of Vietnam were involved in this cross-sectional study. The approach used was convenient cluster sampling with a self-administered questionnaire by the participants. Network analysis for pairwise correlations between psychological factors was estimated . Important factors in the network analysis were calculated using centrality indices including node strength (S), closeness (C), and betweenness (B). The higher score of S, C, and B indicate the more importance of the node. The results obtained from the network analysis of eight psychological factors showed that 'teaching quality' was mostly connected with other factors overall, while the 'training programme' was seen in both genders and freshman students. 'Study conditions' and 'training programme' were mostly connected with other factors in junior and senior students, respectively. The strong pairwise correlation was confirmed: management system and evaluation activity, followed by study environment and study conditions, and teaching quality and training programme. Additionally, nodes with high centrality were shown to be 'management system' (S = 0.97, C = 0.019, B = 1), and 'training programme' (S = 0.96, C = 0.021, B = 4). Our study findings indicate that satisfaction with the training programme amongst eight psychological factors is the most important factor affecting academic pressure among medical students. The training programme is linked with teaching quality, whereas the management system is correlated with evaluation activity.

Estimating cost-effectiveness of screening for colorectal cancer in Vietnam.

Background:Presently, there are no national screening programs for cancer in Vietnam. This study aimed to analyze the cost-effectiveness of an annual colorectal cancer (CRC) screening program from the healthcare service provider's perspective for the Vietnamese population.Methods:The economic model consisted of adecision tree and aMarkov model. Adecision tree was constructed for comparing two strategies, including ascreening group with aguaiac-based fecal occult blood test (gFOBT) and ano-screening group in general populations, aged 50 years and above. The Markov model projected outcomes over a25-year horizon. The cost-effectiveness outcome was the incremental cost-effectiveness ratio (ICER) represented by costs per quality-adjusted life-years (QALYs).Results:When compared with no screening, ICER was $1,388per QALY with an increased cost of $ 43.98 and again of 0.032 QALY (Willingness to pay $2,590). The uptake rate of gFOBT, cost of colonoscopy, and the total cost of screening contributed to the largest impact on the ICER. PSA showed that results were robust to variation in parameter estimates, with annual screening remaining cost-effective compared with no screening.Conclusion:Our screening strategy could be considered cost-effective compared to ano screening strategy. Our findings could be potentially used to develop aCRC national screening program.

Attention Deficit Hyperactivity Disorder (ADHD) and Associated Factors Among First-Year Elementary School Students.

PURPOSE: Attention deficit hyperactivity disorder (ADHD) is a mental health disorder commonly in children. This study aimed to examine the prevalence of ADHD and risk factors among first-year pupils in Vietnam's urban city. PATIENTS AND METHODS: A cross-sectional study was conducted in four randomly selected primary schools. Information on 525 pupils in grade 1 (ages 6 to 7 years) was collected from 525 parents/caregivers and 28 teachers. We used the Vanderbilt Assessment Scales with two separate versions for parents and teachers to screen children with ADHD symptoms. RESULTS: Among the total of 525 pupils, 24 (4.6%) were found to have ADHD symptom types (boy: 6.5%; girl: 2.1%). The combined ADHD type accounted for the highest proportion of 3.4%, followed by predominantly inattentive and predominantly hyperactivity type. ADHD prevalence rated by teachers was higher than those rated by parents. High agreement between parents and teachers was reported (κ > 0.6). The risk of ADHD increased in male participants (aOR=4.90, 95% CI 1.51-15.85), those having a first-degree relative with ADHD (aOR=85.2, 95% CI 1.66-4371.8), in-utero exposure to tobacco smoke (aOR=4.78, 95% CI 1.31-17.44), and prenatal alcohol drinking (aOR=8.87, 95% CI 2.29-34.42). CONCLUSION: These findings suggest the importance of ADHD screening for pupils attending elementary schools, particularly those with a family history of ADHD. Public health programs should reduce prenatal exposure to the potential risk factors of ADHD (smoking and alcohol consumption).

HER2Ile655Val Single Nucleotide Polymorphism Associated with Early-Onset Breast Cancer Susceptibility: A Systematic Review and Meta-Analysis.

ackground: Human epidermal growth factor receptor 2 (HER2) plays an important role in the development and progression of breast cancer. To understand the precise association, this meta-analysis was conducted to estimate the association between HER2Ile655Val single nucleotide polymorphism (SNP) and susceptibility to early-onset breast cancer. METHODS: A comprehensive database retrieval from PubMed, Embase, Web of Science and Google Scholar was pooled to investigate links between the HER2Ile655Val SNP and risk of breast cancer. Adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to appraise the association under the additive model (Ile vs. Val), dominant model (Val/Val + Ile/Val vs. Ile/Ile), and recessive model (Val/Val vs. Ile/Val + Ile/Ile). RESULTS: Seventeen relevant studies with 11,749 cases and 8,105 controls were finally included. We found that HER2Ile655Val SNP is associated with an increased risk of breast cancer in an additive and dominant model. In the subgroup analysis with age stratification, a significant association between the HER2 codon 655 SNP and the risk of breast cancer was found in young women in an additive, dominant, and recessive model; conversely, no significant associations were indicated in older women. In the breast cancer subgroup, HER2Ile655Val SNP was significantly associated with younger age women with breast cancer in the dominant model. In contrast, no association between the HER2 codon 655 SNP and age was found in control populations. CONCLUSION: Our findings suggest that the Val allele in HER2 codon 655 SNP is strongly associated with breast cancer susceptibility in the young female population and is also significantly associated with younger age in women with breast cancer. HER2Ile655Val SNP might be a susceptibility factor that favours early-onset breast cancer.

Economic burden of alcohol-related cancers in the Republic of Korea.

BACKGROUND: Cancer is a major burden of disease and alcohol consumption is one of the major risk factors of cancer. This study aimed to estimate the economic burden of cancer types attributable to alcohol consumption in the Republic of Korea. METHODS: This study estimates the direct and indirect costs of cancer types attributable to alcohol consumption by applying cost-of-illness methods using the human capital approach and prevalence-based estimates. Claims data from the National Health Insurance Service for 2011-2016 were used. RESULTS: In Korea, there were 297,304 alcohol consumption-related cancer cases, of which 14,186 (4.8 %) were attributable to alcohol consumption in 2016. From 2011-2016, the socioeconomic burden of cancer attributable to alcohol consumption in Korea has increased steadily, even considering inflation adjustment. The total economic burden of cancer attributable to alcohol consumption in 2016 in Korea was approximately $476 million, of which $119 million were direct costs and $357 million were indirect costs. According to our analysis of annual cost per patient, the average costs were $37,432 for men and $11,930 for women. CONCLUSIONS: The economic burden of cancer types attributable to alcohol consumption in Korea is substantial and has increased between 2011 and 2016, mainly due to an increased number of patients.

Cancer Risk Studies and Priority Areas for Cancer Risk Appraisal in Uganda.

Background: Research into aetiologies and prevention of the commonest cancers and implementation of primary and secondary prevention can reduce cancer risk and improve quality of life. Moreover, monitoring the prevalence of cancer risk factors in a specific population helps guide cancer prevention and early detection efforts and national cancer control programming. Objective: This article aims to provide the scope and findings of cancer risk studies conducted in Uganda to guide researchers, health-care professionals, and policymakers. Methods: Between November 2019 to January 2020, we searched peer-reviewed published articles in Pubmed, EMBASE and Cochrane Library (Cochrane central register of controlled trials-CENTRAL). We followed the recommendation of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses - the PRISMA. The primary focus was to identify cancer risk and prevention studies conducted in Uganda and published in peer-reviewed journals from January 2000 and January 2020. We used key Boolean search terms with their associated database strings. Results: We identified 416 articles, screened 269 non-duplicate articles and obtained 77 full-text articles for review. Out of the 77 studies, we identified one (1%) randomized trial, two (2.5%) retrospective cohort studies and 14 (18%) case-control studies, 46 (60%) cross-sectional studies, five (6.4%) ecological studies, three panel studies (4%) and six (8%) qualitative studies. Cervical cancer was the most studied type of cancer in Uganda (23.4%, n = 18 studies), followed by lymphomas - both Hodgkin and Non-Hodgkin sub-types (20.7%), n = 16 studies) and breast cancer (15.6%, n = 12 studies). In lymphoma studies, Burkitt lymphoma was the most studied type of lymphoma (76%, n = 13 studies). The studies concentrated on specific cancer risk awareness, risk perceptions, attitudes, uptake of screening, uptake of human papillomavirus vaccination, the prevalence of some of the known cancer risk factors and obstacles to accessing screening services. Conclusion: The unmet need for comprehensive cancer risk and prevention studies is enormous in Uganda. Future studies need to comprehensively investigate the known and putative cancer risk factors and prioritize the application of the higher-hierarchy evidence-generating epidemiological studies to guide planning of the national cancer control program.

Diabetes-Related Distress and Its Associated Factors Among Patients with Diabetes in Vietnam.

BACKGROUND: Psychometric properties are regarded as one of the significant contributors related to diabetes treatment efficacy. Diabetes-related distress (DD) is one of the emotional burdens. The aims of this study were to investigate the prevalence of DD and to determine its associated factors among Vietnamese diabetic patients. METHODS: A cross-sectional study was conducted at a single medical center in the central of Vietnam. A total of 138 eligible DM outpatients were invited and a total of 112 patients who completed the questionnaire were utilized in this analysis using convenience sampling. DD was assessed using the diabetes distress scale (DDS). The participant's sociodemographic and clinical information was obtained through face-to-face interviews and medical records. Multivariate logistic regression was used to determine independent factors associated with the presence of DD. RESULTS: Approximately, 12.5% of the patients experienced DD based on DDS self-administered questionnaire. The rates of mild/moderate and high distress were 8.0% and 4.5%, respectively. DD was found to be significantly higher in type 1 DM (p=0.04), insulin only in treatment regime (p=0.04), physical inactivities (p=0.02), times of mild hypoglycemia (time/month) (p=0.01), and fasting plasma glucose (mmol/l) (p=0.04). The occurrence of distress among DM patients was negatively correlated with their age and amount of physical exercise. Meanwhile, poor HbA1c control (HbA1c≥7%) was associated with an increased occurrence of diabetes distress. CONCLUSION: The findings of single medical center in Vietnam highlights that DD is prevalent among DM patients. It should be of marked concerns, particularly the type 1 diabetic patients, younger age, and poor glycemic control patients.

Trends in prediabetes and diabetes prevalence and associated risk factors in Vietnamese adults.

OBJECTIVES: The prevalence of diabetes mellitus is rapidly increasing in Vietnam, particularly among adults aged over 45 years. This study estimated trends in diabetes and prediabetes prevalence and determined risk factors in Vietnamese adults (over 45 years). METHODS: A cross-sectional study was conducted based on data from an annual diabetes screening program among people aged 45-69 years in an urban city in central Vietnam (Da Nang). Joinpoint regression analyses were performed to calculate the annual percentage change and ptrend-values. Multinomial logistic regression analysis was used to determine risk factors. RESULTS: In total, 3,765 men and 9,149 women were included in this analysis. The age-adjusted prevalence of diabetes and prediabetes in 2017 was 11.4% and 52.9%, respectively. The prevalence of diabetes was higher in men (15.1%) than in women (10.3%), but that of prediabetes was similar in both genders (53.4% vs. 52.8%). The prevalence of prediabetes significantly increased during the study period, whereas no upward or downward trend for diabetes was observed. The prevalence of obesity, abdominal obesity, hypertension, and dyslipidemia showed no obvious trend. Obesity, a high waist-to-hip ratio, hypertension, more severe abdominal obesity, and dyslipidemia were significantly associated with a higher risk of diabetes and prediabetes. CONCLUSIONS: Diabetes and prediabetes were more prevalent among people aged over 45 years than in the general population. Da Nang has experienced a marked increase in the prevalence of prediabetes. These findings have significant implications regarding the need for nationwide public health interventions and management aiming at diabetes prevention and control.

Measurement of Health-Related Quality of Life Among Colorectal Cancer Patients Using the Vietnamese Value Set of the EQ-5D-5L.

PURPOSE: Health-related quality of life (HRQoL) is an important construct in clinical settings, and it is crucial that it should be properly measured. As the EuroQol-5-dimensions-5 levels (EQ-5D-5L) is more effective for such measurement than the 3-level model, data on economic models, clinical studies, and public health evaluations previously collected through the EQ-5D-3L need to be revaluated using the EQ-5D-5L. This study evaluated colorectal cancer (CRC) patients' HRQoL scores using the Vietnamese EQ-5D-5L value set. PATIENTS AND METHODS: The cross-sectional study included CRC patients treated at a tertiary public hospital. HRQoL was assessed using the EQ-5D-5L, and HRQoL utility scores were calculated using the Vietnamese value set. Tobit regression examined factors associated with HRQoL. RESULTS: The analysis included 197 CRC patients. Ages ranged from 20 to 87 years (M = 57.64, SD = 13.5); 42.2% and 57.8% were diagnosed with cancer of the colon or rectum/anus, respectively. Mean EQ-5D-5L was 0.561 (range, -0.5115 to 1). Most participants experienced anxiety/depression (88%), followed by pain/discomfort (87%), mobility (71%), usual activity (69%), and self-care (67%). Advanced CRC stage (stage II: ß -0.303, se 0.08; stage III: ß -0.305, se 0.07; stage IV: ß -0.456, se 0.07) and surgery (ß -0.113, se 0.05) were negatively associated with EQ-5D-5L scores. Advanced education (high school: ß 0.273, se 0.07); college/vocational: ß 0.134se 0.05; university/higher: Coef 0.213, se 0.08;) and older age (age group 35-44: ß 0.253, se 0.10; 45-54: ß 0.327, se 0.09; 55-64: ß 0.355 se 0.09; 65+ ß 0.204, se 0.09) were positively associated with EQ-5D-5L scores. CONCLUSION: Patients in advanced CRC stages or undergoing surgery experienced lower HRQoL and higher prevalence of anxiety/depression and pain/discomfort. Older age and high educational attainment predicted high HRQoL. This study provides information on CRC patients' health utility based on various patient characteristics, which can be used in future economic evaluations.
