Jemna DV, David M, Bonnal L, Oros C. Socio-economic inequalities in the use of flu vaccination in Europe: a multilevel approach. HEALTH ECONOMICS REVIEW 2024; 14:61. [PMID: 39083186 PMCID: PMC11292999 DOI: 10.1186/s13561-024-00535-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Accepted: 07/15/2024] [Indexed: 08/03/2024]
Abstract
BACKGROUND The European-wide statistics show that the use of flu vaccination remains low and the differences between countries are significant, as are those between different population groups within each country. Considerable research has focused on explaining vaccination uptake in relation to socio-economic and demographic characteristics, health promotion and health behavior factors. Nevertheless, few studies have aimed to analyze between-country differences in the use of flu vaccination for the EU population. To address this gap, this study examines the socio-economic inequalities in the use of influenza vaccination for the population aged 15 years and over in all 27 EU Member States and two other non-EU countries (Iceland and Norway). METHODS Using data from the third wave of European Health Interview Survey (EHIS) 2019, we employed a multilevel logistic model with a random intercept for country, which allows controlling simultaneously the variations in individuals' characteristics and macro-contextual factors which could influence the use of flu vaccination. In addition, the analysis considers the population stratified into four age groups, namely adolescents, young adults, adults and elderly, to better capture heterogeneities in flu vaccination uptake. RESULTS The main findings confirm the existence of socio-economic inequalities between individuals in different age groups, but also of significant variation between European countries, particularly for older people, in the use of influenza vaccination. In this respect, income and education are strong proxy of socio-economic status associated with flu vaccination uptake. Moreover, these disparities within each population group are also explained by area of residence and occupational status. Particularly for the elderly, the differences between individuals in vaccine utilization are also explained by country-level factors, such as the type of healthcare system adopted in each country, public funding, personal health expenditure burden, or the availability of generalist practitioners. CONCLUSIONS Overall, our findings reveal that vaccination against seasonal influenza remains a critical public health intervention and bring attention to the relevance of conceiving and implementing context-specific strategies to ensure equitable access to vaccines for all EU citizens.

Abstract
BACKGROUND Compared to workers of larger companies it is less clear what health promoting interventions might be beneficial for employees of small businesses and self-employed individuals. OBJECTIVE Our aim was to critically appraise trials investigating health promotion programs among small business workers and self-employed individuals, by means of a systematic review. METHODS We conducted a search of primary studies using MEDLINE, Web of Science, LIVIVO and the Cochrane library. Our assessment followed the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions and PRISMA. RESULTS We identified six trials including 5,854 participants from Asia, North America and Australia. Most were of moderate methodological quality, only one was of low quality. Some of the supervised psycho-educational lifestyle programs focusing on individual behavior changes showed benefits in terms of stress reduction and increased physical activity levels among small enterprise employees. CONCLUSIONS There is a huge knowledge gap on evidence-based health promotion interventions for self-employed and for small business workers, especially in Europe.

Lu J, Dong Y, Zhang X, Wang Y, Zhou Z. The relationship between public risk preference and the underuse or overuse of preventive health services in the information age. Prev Med Rep 2024; 41:102727. [PMID: 38633208 PMCID: PMC11021990 DOI: 10.1016/j.pmedr.2024.102727] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 04/10/2024] [Accepted: 04/11/2024] [Indexed: 04/19/2024] Open
Abstract
The underuse or overuse of preventive health services by individuals is an outward behavioural reflection of their attitude towards disease risk, and they are strongly influenced by their information-acquisition ability. Therefore, we try to explore the relationship among the public risk preference, information-acquisition ability and underuse or overuse of preventive health services, in order to provide decision-making basis in the Information Age. The survey surveyed 2,211 respondents aged ≥ 18 in China from September to December 2019. Taking cancer screening as an example, the multiple price list (MPL) test and item response theory (IRT) model were used to measure individual risk preference and information-acquisition ability. The Logit model and Tobit model were used to estimate the relationship between risk preference, information-acquisition ability and underuse or overuse of preventive health services. Risk-seeking individuals were more likely to underuse preventive health services, while risk-averse individuals were more likely to overuse such services. Information-acquisition ability may improve the underuse of preventive health services in risk-seeking individuals but exacerbate the overuse of preventive health services in risk-averse individuals. Among the investigated information channels, the Internet is the most effective way for the public to obtain information. It is necessary to change the public's incorrect perception of disease risks and risks associated with preventive health services. In the rapid development of the Information Age, improving public information-acquisition ability is a practicable way to correct the negative relationship between risk preference and individuals' underuse or overuse of preventive health services.

Socioeconomic Disparities in the Association Between All-Cause Mortality and Health Check-Up Participation Among Healthy Middle-Aged Workers: A Nationwide Study. J Korean Med Sci 2023; 38:e384. [PMID: 38147834 PMCID: PMC10752744 DOI: 10.3346/jkms.2023.38.e384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Accepted: 09/27/2023] [Indexed: 12/28/2023] Open
Abstract
BACKGROUND This study assessed the relationship between non-participation in health check-ups and all-cause mortality and morbidity, considering socioeconomic status. METHODS Healthy, middle-aged (35-54 years) working individuals who maintained either self-employed or employee status from 2006-2010 were recruited in this retrospective cohort study from the National Health Insurance Service in Korea. Health check-up participation was calculated as the sum of the number of health check-ups in 2007-2008 and 2009-2010. Adjusted hazard ratio (HR) and 95% confidence interval (CI) of all-cause mortality were estimated for each gender using multivariable Cox proportional hazard models, adjusting for age, income, residential area, and employment status. Interaction of non-participation in health check-ups and employment status on the risk of all-cause mortality was further analyzed. RESULTS Among 4,267,243 individuals with a median 12-year follow-up (median age, 44; men, 74.43%), 89,030 (2.09%) died. The proportion (number) of deaths of individuals with no, one-time, and two-time participation in health check-ups was 3.53% (n = 47,496), 1.66% (n = 13,835), and 1.33% (n = 27,699), respectively. The association between health check-up participation and all-cause mortality showed a reverse J-shaped curve with the highest adjusted HR (95% CI) of 1.575 (1.541-1.611) and 1.718 (1.628-1.813) for men and women who did not attend any health check-ups, respectively. According to the interaction analysis, both genders showed significant additive and multiplicative interaction, with more pronounced additive interaction among women who did not attend health check-ups (relative excess risk due to interaction, 1.014 [0.871-1.158]). CONCLUSION Our study highlights the significant reverse J-shaped association between health check-up participation and all-cause mortality. A pronounced association was found among self-employed individuals, regardless of gender.

Acta Diabetol 2022; 59:793-801. [PMID: 35279754 PMCID: PMC9085697 DOI: 10.1007/s00592-022-01869-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Accepted: 02/15/2022] [Indexed: 11/25/2022]
Abstract
AIMS Workplace demands, support, and relationships differ according to employment status (e.g., employment that is full-time, part-time, or self-employed) and may lead to unequal opportunities to keep diabetic appointments. We investigated the association between employment status and outpatient diabetic appointment non-attendance among working-age adults with type 2 diabetes. METHODS This was a secondary analysis of a cluster-randomized trial (the Japan diabetes outcome intervention trial 2 large-scale trial). The analysis included 2010 trial participants (40-65 years old) with type 2 diabetes who were regularly followed by primary care physicians (PCPs). The outcome measure was the first non-attendance (defined as a failure to visit a PCP within 2 months of the original appointment) during the one-year follow-up. The association between baseline employment status and non-attendance was examined using Cox proportional hazard model in men and women. RESULTS During the 1279 and 789 person-year follow-up periods, 90 men and 34 women, respectively, experienced their first appointment non-attendance. Among men, self-employed participants had a higher risk of non-attendance compared with full-time employees (adjusted HR, 1.84; 95% CI, 1.15, 2.95). The trial intervention (attendance promotion) was associated with a significantly reduced risk of non-attendance among self-employed participants (HR, 0.51; 95% CI, 0.26, 0.99). Among women, a significant association between employment status and non-attendance was not observed. CONCLUSIONS Self-employed men with type 2 diabetes had a twofold increased risk of non-attendance than did full-time employees. Our study suggests that self-employed men with type 2 diabetes should be targeted for interventions promoting appointment adherence.

Abstract
Finding effective strategies to increase participation in cervical cancer screening (CCS), breast cancer screening (BCS) and colorectal cancer screening (CRCS) for women is an important public health issue. Our objective was to examine combined patterns of participation in these three screenings and investigate the factors associated with non-participation in each. We analyzed 115,254 women aged 40-69 who were age-eligible for all three screenings from a 2016 nationally representative cross-sectional survey in Japan. Eight screening patterns were defined as full-participation (CCS + BCS + CRCS), partial-participation (CCS + BCS, CCS + CRCS, BCS + CRCS, CCS, BCS, CRCS), and non-participation (none). Multinomial logistic regression analysis adjusted for age, marital status, educational attainment, employment status, self-rated health, current hospital visits, and smoking status was performed to evaluate the factors associated with each screening pattern, using full-participation as the reference category. Screening rates for cervical, breast, and colorectal cancer were 45.0%, 46.2%, and 40.4%, respectively. Although only 26.9% of women participated in all three screenings, more than 60% participated in at least one screening. Unstable employment, low educational attainment, low self-rated health, and current smoker were associated with both non-participation and partial-participation, especially single-participation in cervical and breast cancer screening. For example, self-employed women were more likely to be non-participants [aOR 2.80 95%CI: 2.65-2.96], single-participants for CCS [aOR 2.87 95%CI: 2.57-3.20], and BCS [aOR 2.07 95%CI: 1.85-2.33] than permanent workers. It may be useful to consider related factors for non-participation patterns to encourage partial-participants to have other cancer screenings by utilizing one cancer screening as an opportunity to provide information about other screenings.

Abstract
Backgroundcxs Early detection of breast cancer is effective for prolonging survival, but the participation rate in breast cancer screening among target Japanese women remains low. This study examined the relationships between tendencies in decision-making under conditions of uncertainty, health behaviors, demographics, and breast cancer screening participation in Japanese women. Methods Secondary analysis was performed using data from the 2017 Keio Household Panel Survey (KHPS). The study population consisted of 2945 households. Data were obtained from the KHPS for women aged 40 years or older. Breast cancer screening participation in the past year, risk aversion, time preference, health behaviors (e.g., smoking, alcohol consumption, and medical treatment received in the past year), and demographic variables were analyzed. Results Data from 708 women were analyzed. Among the respondents, 28.8% had attended breast cancer screening in the past year. Factors found to significantly contribute to breast cancer screening participation included higher risk aversion (odds ratio [OR], 2.34; 95% confidence interval [CI] = 1.03–5.32; p = 0.043), medical treatment received in the past year (OR, 1.56; 95% CI = 1.06–2.30; p = 0.026), higher self-rated health (OR, 1.47; 95% CI = 1.18–1.83; p = 0.001), living above the poverty line (OR, 2.31; 95% CI = 1.13–4.72; p = 0.022), and having children (OR, 1.57; 95% CI = 1.02–2.42; p = 0.042). Factors significantly associated with non-participation in breast cancer screening were smoking (OR, 0.20; 95% CI = 0.10–0.42; p < 0.000), alcohol consumption (OR, 0.56; 95% CI = 0.37–0.86; p = 0.007), being self-employed (OR, 0.22; 95% CI = 0.10–0.46; p < 0.000), and being unemployed (OR, 0.48; 95% CI = 0.26–0.90; p = 0.022). No significant relationship was observed between time preference and screening participation. Conclusions The results indicate that women who recognize the actual risk of developing breast cancer or have high awareness of breast cancer prevention tend to participate in breast cancer screening. Barriers to screening participation are not working for an organization that encourages screening and low income.

Abstract
BACKGROUND/OBJECTIVES Concerns about regional disparities in heathy eating and nutritional status among South Korean adults are increasing. This study aims to identify the magnitude of regional disparities in diet and nutritional status among Korean adults who completed the 2017 Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS The participants were a nationally representative sample of Korean adults aged 19 years and older from the 2017 KNHANES (n = 6,126). We employed the svy commands in STATA to accommodate the complex survey design. The relative concentration index (RCI), absolute concentration index (ACI) and index of disparity were used to measure regional nutritional inequalities. RESULTS Overweight and obese adults were more prevalent among the poor than among the rich in urban areas (RCI = -0.041; P < 0.05), while overweight and obese adults were more prevalent among the rich than among the poor in rural areas of South Korea (RCI = 0.084; P < 0.05). Economic inequality in fruit and vegetable intake ≥ 500 g per day was greater in rural areas than in urban areas in both relative size (RCI = 0.228 vs. 0.091, difference in equality = 0.137; P < 0.05) and absolute size (ACI = 0.055 vs. 0.023, difference in equality = 0.032; P < 0.05). CONCLUSIONS This study provides useful information identifying opposite directions in the relative concentration curves between urban and rural areas. Adult overweight/obesity was more prevalent among the poor in urban areas, while adult overweight/obesity was more prevalent among the rich in rural areas. Public health nutrition systems should be implemented to identify nutritional inequalities that should be targeted across regions in South Korea.

Anticancer Effect of Mountain Ginseng on Human Breast Cancer: Comparison with Farm-Cultivated Ginseng. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:2584783.

Abstract
Mountain ginseng has been used generally as a pharmacopuncture for cancer therapy in clinical practice in Northeast Asia. Nonetheless, there have been few scientific reports for the anticancer action of mountain ginseng. In this study, we investigated whether mountain ginseng extract (MGE) could inhibit the growth of breast cancer in in vitro and in vivo models. MGE showed stronger cytotoxicity than farm-cultivated ginseng extract (FGE) through promoting ROS generation. Also MGE dose-dependently brought about mitochondrial dysfunction in MCF-7 cells. In addition, MGE induced apoptosis through enhancing the activities of caspase-3/7 by regulation of expression of Bcl-2, Bax, cytochrome c, and cleaved caspase-3 in the MCF-7 cells. Consistent with the in vitro results, MGE significantly reduced tumor weights compared with FGE in mice transplanted with MCF-7 cells, and it regulated the expression of apoptosis-related proteins, such as Bcl-2, Bax, cytochrome c, cleaved caspase-3, and cleaved PARP, in the tumor tissues. Additionally, MGE included higher total ginsenoside contents than FGE. In conclusion, MGE, which is richer in ginsenosides, exerts a stronger anticancer action than FGE in breast cancer. The anticancer action of MGE may be closely correlated with caspase-mediated apoptosis through upregulating ROS generation. Therefore, these findings may be helpful for a clinical understanding of the anticancer mechanism of MGE for breast cancer patients.

Abstract
OBJECTIVES This study evaluated the incidence of colorectal cancer (CRC) according to the number of metabolic syndrome (MetS) components. METHODS Using health checkup and insurance claims data of 6,365,409 subjects, the occurrence of CRC according to stage of MetS by sex was determined from the date of the health checkup in 2009 until December 31, 2018. RESULTS Cumulative incidence rates (CIR) of CRC in men and women was 3.9 and 2.8 per 1000 (p < 0.001), respectively. CIR of CRC for the normal, pre-MetS, and MetS groups in men was 2.6, 3.9, and 5.5 per 1000 (p < 0.001) and CIR in women was 2.1, 2.9, and 4.5 per 1000 (p < 0.001), respectively. Compared with the normal group, the hazard ratio (HR) of CRC for the pre-MetS group was 1.25 (95% CI 1.17-1.33) in men and 1.09 (95% CI 1.02-1.17) in women, and the HR of CRC for the MetS group was 1.54 (95% CI 1.43-1.65) in men and 1.39 (95% CI 1.26-1.53) in women after adjustment. CONCLUSIONS We found that MetS is a risk factor for CRC in this study. Therefore, the prevention and active management of MetS would contribute to the prevention of CRC.

Implementation of Isoniazid Preventive Therapy Among HIV-Infected Children at Health Facilities in Nairobi County, Kenya: A Cross-Sectional Study. East Afr Health Res J 2019; 3:141-150. [PMID: 34308207 PMCID: PMC8279276 DOI: 10.24248/eahrj-d-19-00005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Accepted: 10/29/2019] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND HIV is the strongest risk factor for developing tuberculosis (TB) among people with latent or new Mycobacterium tuberculosis infection. Isoniazid preventive therapy (IPT) reduces the risk of active TB among people living with HIV by up to 62%. Despite evidence that IPT is safe and efficacious, its provision remains low globally. The current study aimed at documenting IPT uptake, adherence, and completion rates, as well as the correlates of IPT uptake among HIV-infected children in Kenya. The study also assessed the knowledge, attitude, and practices of health-care workers (HCWs) with regard to IPT. METHODS A health facility-based cross-sectional study was conducted. Data were collected from caregivers of HIV-infected children as well as HCWs using an interviewer-administered questionnaire. Logistic regression was used to determine the factors associated with IPT uptake. RESULTS The study enrolled 111 child-caregiver dyads. Most of the caregivers were female (n=75, 77.3%) and HIV-positive (n=82, 85.4%). The majority of children were male (n=65, 58.6%) and on ART (n=106, 95.5%). Overall, 59 children were on IPT (uptake of 53.2%, 95% confidence interval [CI], 43.9% to 62.4%). Out of the 25 children who had been on IPT for more than 6 months, 22 (88.0%) successfully completed the 6-month course of treatment. Further, 27 of the 34 children (78.4%) who were on IPT at the time of the study demonstrated satisfactory adherence to the therapy (no doses missed). The caregivers' attributes that were associated with IPT uptake included having a secondary school education (adjusted odds ratio [aOR] 0.13; 95% CI, 0.03 to 0.67) and having been on IPT (aOR 27.50; 95% CI, 5.39 to 140.28). The characteristics of children that were significantly associated with IPT uptake were higher median baseline CD4 count (P=.007) and higher median current CD4 count (P=.024). CONCLUSION The study demonstrated suboptimal IPT uptake but favourable adherence and treatment completion rates. There was almost universal awareness of IPT within the study sample. Furthermore, the majority of the HCWs had a favourable attitude towards IPT. However, the attendant IPT practices were inadequate, with majority of HCWs reporting that they had never initiated IPT, prescribed IPT within the last 12 months, or renewed an isoniazid prescription.
