A new modality of colorectal cancer screening based on chronic disease management.

BACKGROUND: To develop a new modality of colorectal cancer screening based on chronic disease management (CDM) to improve the participation rate of screening, and maximize the benefits of limited resources. METHODS: Patients under CDM were assigned to screening intervention group (SI) and screening control group1 (SC1), residents from natural community were assigned to screening control group2 (SC2). A parallel controlled community intervention study was performed. Only SI would achieve "one-to-one" intervention services. Meanwhile, 200 subjects were selected from each of the three groups for the Knowledge-Attitude-Practice (KAP) questionnaire before and after intervention, named questionnaire intervention group(QI), questionnaire control group1(QC1) and questionnaire control group2(QC2). The outcome of the intervention was evaluated using the difference-in-differences method and multiple regression analysis. RESULTS: The preliminary screening participation rate was 43.63%(473/1084) in SI, 14.32%(132/922) in SCI, and 5.87%(105/1789) in SC2. The baseline questionnaire showed low knowledge scores in the three questionnaire groups with no statistically significant differences, while attitude scores in QI and QC1 were significantly higher than QC2. The differences between baseline and terminal showed QI increased larger in knowledge and attitude scores than QC1 and QC2, while no difference was detected between QC1 and QC2. CONCLUSION: The colorectal cancer screening model based on chronic disease management effectively improved the screening participation rate, and the "one-to-one" intervention and the inherent characteristics of the patient population under CDM were the core elements of the new modality.

The Danish National Survey of Diet and Physical Activity (DANSDA) 1995-2011-2013: Study design, study participants, participation rate and underreporting.

AIM: This study describes the study design, study participants, participation rate and underreporting in the Danish National Surveys of Diet and Physical Activity (DANSDA) from 1995 to 2011-2013. METHODS: DANSDA are government-funded surveys of food and nutrient intake, physical activity and lifestyle, undertaken to support nutritional policy, risk assessment and public health research. The surveys are cross-sectional based on primarily simple random samples (ages 1-80 years in 1995, 4-75 years in 2000-2013) drawn from the Danish Civil Registration System. Approximately 4800 individuals in 1995, 8200 in 2000-2002, 8400 in 2003-2008 and 7300 in 2011-2013 were invited to participate. Participants completed a seven-day food diary, a physical activity questionnaire (2000-2008), a step diary (2011-2013) and a face-to-face interview. Self-reported anthropometrics (1995-2013) were supplemented with device-based measures (2011-2013). Pedometers were included in 2011-2013. RESULTS: The number of participants included per survey round was 3100-4400. Participant rates decreased from 66% (1995) to 54% (2011-2013). Non-participation was primarily refusal. Ages 18-30 years, 61-75 years (2000-2013), 61-80 years (1995) and low educated and individuals living alone were underrepresented. Underreporting of energy intake among adults ranged from 14% (1995) to 26% (2008). CONCLUSIONS: The methods in DANSDA have been developed to include device-based measures on physical activity and anthropometrics. This has improved the applicability of the results of the survey. The participation rate has fallen, which has affected sample representativity, and underreporting has increased. Future DANSDA surveys should explore and consider new initiatives to counteract non-response and underreporting, with the aim of enhancing data representativeness and applicability.

Assessment of the compliance, influencing factors, and yielding results of liver cancer screening in a high-risk population: A cross-sectional study.

BACKGROUND: The participation and results for liver cancer screening are rarely reported. The aim of this study was to determine the participation rates and factors affecting participation rates as well as to report the detection rate for liver cancer in an organized screening program. METHODS: The organized screening program for liver cancer was conducted in 12 rural sites. The risk of developing liver cancer was initially evaluated for each participant. High-risk individuals were offered α-fetoprotein measurement and ultrasonography examination. Potential risk factors associated with the participation rate were screened by fitted generalized linear mixed logistic regression models through reporting odds ratios (ORs) with 95% CIs. RESULTS: A total of 358,662 eligible participants completed the basic surveys, and 54,745 were evaluated to be at high risk of liver cancer. Of these high-risk individuals, 40,543 accepted the screening services. Determinants of participation for screening behavior included older age, being female, being positive for hepatitis B surface antigen, having a family history of liver cancer, chronic depression, and low income. The detection rate for liver cancer was estimated to be 0.41% (95% CI, 0.35-0.48). CONCLUSIONS: This study reported several significant factors associated with the screening behaviors for liver cancer. LAY SUMMARY: Participation rate and results for liver cancer screening in rural areas are rarely reported. The determinants associated with adherence rates and early detection rate of liver cancer in an organized screening program for liver cancer were assessed. A possible positive correlation between the participation rates and the early detection rate was observed among attendees of screening. These new finds could be beneficial to increasing the participation rate of screening.

A photograph of the researcher on the invitation letter did not affect the participation rate of a postal survey: a randomized study within a trial (SWAT).

OBJECTIVE: Participant recruitment is one of the main challenges in research. It is suggested that including researcher photographs might increase participation rates, but empirical evidence is lacking. This study within a trial (SWAT) aims to assess whether invitation letters including researcher photographs increase the participation rate in the context of a survey on medical second opinions. METHODS: Through 25 local register offices in Berlin and Brandenburg (Germany), we identified a random sample of 9990 persons. We randomly assigned our sample to the intervention group (IG) receiving an invitation letter with researcher photographs and control group (CG) receiving an invitation letter without photographs in a 1:1 ratio. Our primary outcome was the participation rate. Furthermore, we compared participants to non-participants' characteristics. RESULTS: Of 9990 invitations, 9797 could be delivered (IG: 4890, CG: 4907). Of these, 1349 (13.8%) participated. There were 682/4890 (13.9%) participants in the IG and 662/4907 (13.5%) in the CG with an odds ratio of 1.030 (95% confidence interval: 0.918-1.156). Additional analyses on non-participant characteristics did not show any differences. CONCLUSION: We could not find any difference in the participation rates. Our study does not confirm the results of previous studies. The length of our questionnaire may have affected our results. TRIAL REGISTRATION: Queens University Belfast - SWAT Store, SWAT 104.

The Danish Health and Wellbeing Survey: Study design, response proportion and respondent characteristics.

AIMS: This study aimed to describe the study design and respondent characteristics (including non-response analyses) of the Danish Health and Wellbeing Surveys in 2015 and 2019 and a follow-up survey that was carried out during the COVID-19 pandemic in 2020. METHODS: The Danish Health and Wellbeing Survey is the Danish part of the European Health Interview Survey (EHIS). The samples in 2015 (N=12,000) and 2019 (N=14,000) were both based on a simple random selection of individuals aged ⩾15 years from the Danish Civil Registration System. All individuals from the sample in 2019 who were still alive and living in Denmark were reinvited for a follow-up survey in 2020 (N=13,474). Data in all surveys were collected via self-administered questionnaires (web or paper based). The questionnaires in 2015 and 2019 included the EHIS model questionnaire as well as national questions, whereas the questionnaire in 2020 mainly focused on physical and mental health, employment and working lives, and health behaviour. RESULTS: The overall response proportion declined slightly between 2015 (48.4%) and 2019 (47.4%) but went up to 49.8% in the follow-up survey in 2020. Unit non-response was associated with, for example, male sex, younger age, being unmarried and lower educational level but not with degree of urbanisation. In all, 5000 individuals completed the questionnaire in both 2019 and 2020. CONCLUSIONS: The results are in line with most previous research on non-response in health surveys. However, an association between degree of urbanisation and non-response has been suggested in previous studies. This association was not found in our study.

Examining active aging among Iranian provinces: a TOPSIS analysis.

BACKGROUND: Planning and decision-making for the elderly requires a special attention due to the beginning of aging process in Iran. By emphasizing the concept of active aging, determining the status of the elderly like their ability to continue work over time, to attain income and to participate in social and political life is significant. Active aging uses the indicators measuring the non-used potential of the elderly for having an active and healthy aging. This study aimed to determine the level of active aging among the provinces of Iran in 2018 by considering 11 indicators related to elderly's health, well-being and socioeconomic participation. METHODS: The raw data were obtained from Statistical Center of Iran. After establishing the indicators based on the Global Age Watch approach, the provinces were ranked by the TOPSIS method in terms of aging status. RESULTS: The results indicated that only Tehran and Alborz had the highest development level of active aging while 16% of the provinces had a semi-developed status and 77% failed at experiencing a satisfactory welfare, economic and social status. CONCLUSIONS: Four indicators had the highest importance included the percentage of the elderly with a diploma and academic degree, the percentage of the elderly with lower incomes than the median income, the median income of the elderly to the median income of the other people in society, and life expectancy among the 65-year old men. Studying the indicators deeply can result in the appropriate planning for each area in line with the improvement of the elderly status.

Survey Non-Response in COVID-19 Times: The Case of the Labour Force Survey.

During the COVID-19 pandemic, labour-force survey non-response rates have surged in many countries. We show that in the case of the Canadian Labour Force Survey (LFS), the bulk of this increase is due to the suspension of in-person interviews following the adoption of telework within Federal agencies, including Statistics Canada. Individuals with vulnerabilities to the COVID-19 economic shock have been harder to reach and have been gradually less and less represented in the LFS during the pandemic. We present evidence suggesting that the decline in employment and labour-force participation have been underestimated over the March-July 2020 period. We argue that these non-response issues are moderate when analyzing aggregate outcomes, but that researchers should exert caution when gauging the robustness of estimates for subgroups. We discuss practical implications for research based on the LFS, such as the consequences for panels and the choice of public-use versus master files of the LFS.

Pendant la pandémie de COVID-19, le taux de non-réponse aux enquêtes auprès de la population active a explosé dans beaucoup de pays. Nous montrons que dans le cas de l'Enquête canadienne sur la population active (EPA), le gros de cette hausse s'explique par la suspension des entrevues en personne qui a suivi l'adoption du télétravail dans les agences fédérales, y compris à Statistique Canada. Les personnes vulnérables au choc économique de la COVID-19 ont été plus difficiles à joindre et ont été de moins en moins représentées dans l'EPA au cours de la pandémie. Nous montrons, preuves à l'appui, que la diminution de l'emploi et de la participation à la main-d'œuvre est sous-estimée pour la période de mars à juillet 2020. Nous soutenons que la gravité de ces problèmes de non-réponses est modérée quand il s'agit d'analyser des résultats agrégés mais que la prudence s'impose dans l'évaluation de la robustesse des estimations pour les sous-groupes. Nous présentons les conséquences pratiques de cette situation pour les travaux qui reposent sur l'EPA, telles que les effets sur les panels et le choix entre données à grande diffusion et fichiers principaux de l'EPA.

Effects of different invitation strategies on participation in a cohort study of Iranian public sector employees: a cluster randomized trial.

BACKGROUND: Identifying strategies to optimize participation in health studies is one of the major concerns for researchers. The purpose of this study was to evaluate the efficiency of different invitation strategies on participation rate in the Employees' Health Cohort Study of Iran (EHCSIR). METHODS: Two cluster-randomized trials were carried out to assess the outcomes of different invitation strategies. In the first phase, 7 units with 1880 employees (3 hospitals, 3 health centers, and 1 office) were assigned to the three parallel modes of invitation: 1) invitation letter, 2) phone call and 3) Short Message Service (SMS). In the second phase, 6 hospitals with 1633 employees were allocated to two invitation methods: 1) invitation letter, 2) invitation letter plus EHCSIR project introduction video. All groups were followed up by phone calls. A logistic mixed-effects model was used to compare the effectiveness of the strategies. The cost-effectiveness of the interventions was also compared. RESULTS: In the first phase, the participation rates in the invitation letter, phone call, and SMS groups were 27.04% (182/673), 21.55% (131/608), and 22.54% (135/599), respectively. Using an invitation letter was significantly more successful than SMS (Adjusted Odds Ratio = 1.80, 95% CI =1.14 to 2.85). Average Cost-Effectiveness Ratios (ACER) were $1.37, $1.42, and $1.55 for the invitation letter, phone call, and SMS, respectively. In the second phase, adding a project introduction video to the invitation letter did not significantly influence the participation rate (Adjusted OR = 0.58, 95% CI =0.24 to 1.36). The ACER was $1.21 for the invitation letter only and $2.01 for the invitation letter plus the introduction video. CONCLUSIONS: In comparison with the phone call and SMS, the invitation letter is the most effective invitation method for public sector employees to participate in a cohort study. Sending an introduction video did not significantly increase the participation rate compared to sending an invitation letter only.

Factors influencing participation rates in clinical late-effect studies of childhood cancer survivors.

To ensure external validation of a study population in clinical late-effect studies of childhood cancer, the participation rate must be high. This study investigated demographic data in Nordic late-effect studies and potential factors impacting participation rates such as cancer type, time since diagnosis, and duration of clinical examinations. We found 80 published studies originating from 16 cohorts, with median follow-up of 6.0 years (range 3-14). The overall participation rates ranged from 27% to 100%. The highest participation rates were seen in studies of survivors with solid tumors (92%) and the lowest in hematologic malignancies (67%) and central nervous system tumors (73%). The clinical examination in 10 studies (62.5%) lasted for more than 3 hours. Neither duration of the clinical examination nor time since diagnosis seemed to affect the participation rate. We encourage future studies to describe the recruitment process more thoroughly to improve understanding of the factors influencing participation rates.

Higher Participation Rate for Specific Health Checkups Concerning Simultaneous Ophthalmic Checkups.

BACKGROUND: Improving the specific health checkups participation rate is an essential task nationwide; however, studies on measures to accomplish this are limited. This study aimed to examine the influence of ophthalmic checkups on the specific health checkups' participation rate. METHODS: We conducted a postal questionnaire survey on 1,741 countrywide municipalities in Japan from January to February 2019. The questionnaire specifically addressed health checkup participation rates of 2017, health checkups formats (group, individual, or both), simultaneous cancer screenings, simultaneous ophthalmic checkups, and the state of implementation of ophthalmic checkups. We used multiple linear regression analyses to calculate the partial regression coefficients (ßs) and their 95% confidential intervals (CIs) to identify the influence of simultaneous ophthalmic checkups on specific health checkup participation rates. RESULTS: There was a significant association between specific health checkup participation rates and simultaneous ophthalmic checkups (ß: +2.5%; 95% CI, 1.3-3.8) after adjusting for covariates. The fundus photos of all applicants, fundus photos with restrictions, and ophthalmology consultation for all applicants were associated with a significant increase in the specific health checkup participation rate (ß: +2.8%, 95% CI, 1.2-4.4; ß: +2.0%, 95% CI, 0.2-3.9; ß: +7.4%, 95% CI, 1.2-13.6 respectively). CONCLUSIONS: Our results suggest that additional simultaneous ophthalmic checkups as specific health checkups could increase the specific health checkup participation rate.

[Statutory skin cancer screening in Germany : Motivation and motives for participation versus nonparticipation]. / Gesetzliches Hautkrebsscreening in Deutschland : Motivation und Motive zur Teilnahme versus Nichtteilnahme.

BACKGROUND: In 2008, statutory skin cancer screening (sSCS) was introduced in Germany for people aged ≥ 35 years with statutory health insurance (SHI). The aim is to diagnose malignant skin lesions at an early stage, reduce mortality and improve morbidity and quality of life. Although sSCS was introduced more than a decade ago, only a part of the public is aware of it. OBJECTIVES: What are the reasons for the low participation rate in sSCS in the eligible population? MATERIALS AND METHODS: In computer-assisted phone interviews with a representative population sample of N = 1015 persons aged ≥ 18 years with SHI attitude towards skin cancer, rate of use of sSCS and reasons for nonparticipation were surveyed in January 2019. Parts of the data were compared with previous surveys from 2011, 2013 and 2015. RESULTS: Among the 1015 participants 40% were concerned about skin cancer (2011: 45%; 2013: 51%; 2015: 46%). Of the respondents 75.4% were authorised to use sSCS. Of these 52.6% had never participated in sSCS before. However, participation increased with age. Further, the nonparticipation rate for those with a high school-leaving certificate (45%) was significantly lower than for those with a lower schooling level (58%). The option for sSCS was unknown to 35% of nonparticipants. As a reason for nonparticipation 20% mentioned a lack of time, while 58% saw no need for it because they felt healthy. In general, 91% of all respondents considered early preventive examinations to be useful and 66% had already taken part in other preventive examinations. CONCLUSIONS: The low participation rate of about 50% in sSCS and the decreasing concern about skin cancer suggest that further education of the general population about the relevance of skin cancer with a focus on risk groups is necessary.

[Cancer screening rates and characteristics of low-participating groups in Sapporo city].

Objectives　The purpose of this study was to assess the situation of regional cancer screening of individuals in Sapporo city through an independent survey and to identify groups with low cancer screening rates.Methods　We conducted a self-administered questionnaire survey on 3,000 men aged 40 to 69 years and 4,000 women aged 20 to 69 years living in Sapporo (response rate = 32.4%). The contents of the survey were quoted from the health slips of the Comprehensive Survey of Living Conditions related to cancer screening, as well as basic and cancer-related attributes. We analyzed the relationship between cancer screening participation rate, basic attributes, and cancer-related attributes using the χ2 test or logistic regression analysis.Results　The screening rates recorded in this study for gastric, colon, and lung cancers were 67.4%, 59.2%, and 66.1%, respectively in men, and 48.7%, 47.7%, and 53.4%, respectively in women. The screening rates were 52.7% and 56.1% for uterine and breast cancers, respectively.　The participation rate of non-working individuals and those who had National Health Insurance was significantly lower for all cancer types among both men and women. Regarding attributes and cancer screening, the odds ratio of working to non-working individuals was 3.00 to 3.09 in men and 1.41 to 2.46 in women. The odds ratio of non-National Health Insurance individuals was 3.47 to 4.26 in men and 1.47 to 2.52 in women. In addition, there was a significant association between awareness and rates of Sapporo city cancer screening in both men and women, with the exception of stomach cancer screening in women. Furthermore, the odds ratio of awareness was 1.41 to 1.74 in men and 1.24 to 1.48 in women.Conclusion　The cancer types with screening rate below 50% were gastric and colon cancers in women. In men, the screening rate for gastric, colon, and lung cancers exceeded 50%. The cancer-screening rate was found to be low among both non-working men and women, those with national health insurance, or those who do not recognize the Sapporo city cancer screening (regional screening). The characteristics of the group with low participation status in Sapporo city, which was the only parameter not reported in the Comprehensive Survey of Living Conditions, has been clarified.

Feasibility of encouraging participation in colorectal cancer screening campaigns by motivating people through the social network, Facebook.

AIM: To describe the results of a feasibility phase and the expected results of a new approach to increase the participation rate in a Colorectal Cancer Organized Screening Program (CRCSP) through Facebook awareness messages. METHOD: This approach targets people aged 50-74 years, who reside in an urban deprived area and regularly connect to Facebook. The feasibility phase ran over 2 months (December 2018 and January 2019) in six municipalities (Seine-Saint-Denis, France). The full provisional campaign will run over a year. The approach consists of sending electronic awareness messages on the importance of screening for colorectal cancer using a specific Facebook module. Subjects who consent to screening complete a test-kit application form. The eligibility of each subject to participate in screening is determined by a doctor before the kit is sent out. RESULTS: A total of 39 900 people were reached by the feasibility phase campaign, and 9200 were able to watch at least one Facebook message/video. Of those, 4450 people logged to learn more about the CRCSP, 298 applied for a test kit, 160 test kit applicants were eligible to participate and the test completion rate was 41.9%. According to these feasibility results, 366 120 targeted people would connect regularly in the tested area, 141 541 of whom would be interested in a specific promotional message posted on Facebook. Requests could be made for 9770 kits, with 5246 people being eligible to participate in screening. The expected test-completion rate is estimated at 42%-89%. This would represent 5%-11% of the tests carried out in the area during the same period by 'classical' CRCSP. CONCLUSION: Implementation of the Facebook strategy would significantly improve the rate of participation in the CRCSP by mobilizing people with no previous participation, including younger subjects.

Factors Influencing the Proportion of Non-examinees in the Fukushima Health Management Survey for Childhood and Adolescent Thyroid Cancer: Results From the Baseline Survey.

BACKGROUND: After the Fukushima Daiichi Nuclear Power Plant accident, a preliminary ultrasound-based screening for thyroid cancer was conducted to establish a baseline for subsequent evaluations. In this survey, we assessed the relationship between the proportion of non-examinees and characteristics of the target populations. METHODS: After summarizing a regional difference of non-examinees among the population of 359,200 (primary evaluation) and 2,246 (confirmatory testing) individuals who were living in Fukushima Prefecture on March 11, 2011, we estimated odds ratios (ORs) for each characteristic, including age, sex, area of residence, and moving after the accident, based on the proportion of non-examinees for the primary examination and the confirmatory testing, using a multivariate logistic regression model. RESULTS: The dataset included 64,117 non-examinees (primary evaluation) and 194 (confirmatory testing). The logistic regression result indicated that girls were not likely to be non-examinees compared to boys, with adjusted OR of 0.80 (95% confidence interval [CI], 0.78-0.81) for the primary evaluation. Odds were lowest for children 6-10 years old (OR 0.26; 95% CI, 0.25-0.27), and higher for those 11-15 years old (OR 1.28; 95% CI, 1.25-1.32) and over 16 years old (OR 5.30; 95% CI, 5.16-5.43) when compared to children 0-5 years old. Individuals residing in the western part of the prefecture showed higher ORs. There was a higher proportion of non-examinees among those who moved after the accident compared to those who did not in the primary evaluation (OR 1.72; 95% CI, 1.64-1.79). CONCLUSIONS: In addition to demographic characteristics, a change of residence could be a potential factor that influenced the proportion of non-examinees. Our results will help proper interpretation of reports and prospective management of the survey.

[The impact of demographic aging on the pension systems.]

This article discusses the economic consequences of demographic aging. The relevance of this topic is substantiated. The research problem of this article is to assess the strength of the influence of demographic aging on the financial condition of the pension system in the world. Abstracts of the «macroeconomics of aging¼ theses are reviewed with respect to the financial condition of pension systems with an increase in the share of people over working age. A geographical analysis of deviations of the place of countries in the rating of sufficiency of retirement income and the rating of the Melbourne mercer global pension index from the place of countries in the ranking of demographic aging is carried out. The retirement income sufficiency rating for 48 countries, the Melbourne mercer global pension index rating for 25 countries and the UN developed Old age dependency ratio (OADR) are used as the information base. It is concluded that there is no significant correlation between the aging of the population on the one hand and the financial condition of pension systems on the other. Additionally, it was concluded that there is a certain pattern between the strength of the influence of demographic aging and the economic and geographical region. A possible theoretical justification of the thesis of the thesis «macroeconomics of aging¼ is given. Non-demographic factors of influence on the financial condition of pension systems are considered.

The participation rate of migrant women in gestational diabetes screening in Austria: a retrospective analysis of 3293 births.

PURPOSE: This study evaluated the extent to which migrant women participate in the mandatory oral glucose tolerance test (OGTT) for gestational diabetes mellitus (GDM) screening in Austria. METHODS: A retrospective data analysis was carried out of births at an obstetrics unit in a university hospital between January 2013 and December 2015. The inclusion criteria were singleton pregnancies, live births, birth weight ≥ 3500, and no preexisting diabetes mellitus. The patient's extramurally obtained OGTT values and history of GDM were checked. If the mother's country of birth was not Austria, the woman was classified as a migrant. Three groups were defined: group 1-women with normal OGTT; group 2-women with pathological OGTT; and group 3-women without OGTT or with an incomplete OGTT. MAIN OUTCOME MEASURES: Numbers of complete and incomplete OGTTs and rate of women with pathological OGTTs not treated in accordance with the guidelines among mothers born in Austria or migrants. The groups were compared using the t-test, chi-squared test, or Fisher's exact test. RESULTS: A total of 3293 births met the inclusion criteria, and 43.52% of all mothers were migrants; 16.8% of all women had pathological OGTT findings. Only 60.1% of the latter received treatment in accordance with the guidelines. The proportion of mothers born in Austria who did not have OGTTs, or only incomplete ones, was 5.4%. In the group of migrant women, the corresponding figure was 10.5% (P < 0.01). CONCLUSIONS: Migrant women have significantly lower rates of participation in GDM screening.

Impact of stopping sending colorectal cancer screening test kits by regular mail.

OBJECTIVE: From 2009 to 2013, the French colorectal cancer screening program (CRCSP) provided for a medical phase and a phase of systematic mailing of the test kit (SMTK) to people who could not participate in the medical phase. After 2013, the SMTK was abandoned in most districts. This study aims to analyze the impact of this termination. STUDY DESIGN: This was a descriptive and cohort study. METHODS: The study concerned a cohort of 143,989 people (aged 50-74 years) living in Seine-Saint-Denis (France), invited to participate in the 2013 campaign (with SMTK) and in the 2015 campaign (without SMTK). The impact of SMTK termination was analyzed in terms of the difference between the participation rates and between the delay (expected vs observed) in performing the screening test in 2015. These differences were described based on previous solicitation in the CRCSP. Expected rates and expected delay were estimated in a Monte Carlo simulation. RESULTS: The participation rate observed (20.0%) was higher than expected (16.1% [15.9-16.3]). People who have never had a SMTK between 2007 and 2013 (80.0% [79.3-80.7] vs 69.6%) and those who participated in all campaigns before 2015 (97.0% [96.7-97.3] vs 82.6%) had an observed rate lower than expected. The delay observed (4.2 months) was longer than expected (2.5 months). CONCLUSION: The sudden termination certainly contributed to the extension of the delay. However, it did not have a major impact on the participation rate, partly due to information campaigns on the new screening test. In this cohort, the low participation would be explained better by the behavior in the previous campaigns than by the lack of SMTK.

Predictors of Post-Treatment Employment for Individuals with Substance Use Disorders.

This study examined the influence of gender, post-treatment issue severities, and treatment participation rate on the post-treatment employment status of consumers with substance use disorders. The study analyzed the archival data of 100 unemployed and underemployed participants from a substance abuse intensive outpatient program. We found significant differences in the characteristics of gender, severity of alcohol use, drug use, psychiatric issues, and treatment participation rate. Female gender and low treatment participation rates negatively predicted employment. This study increased understanding about the interplay of alcohol, drug, and psychiatric influences on post-treatment employment status.

Evaluation of the personalized invitation of Czech citizens to screening programs.

The Czech population has high burden of malignant tumors, and screening programs are therefore an essential part of cancer control policy. At the beginning of 2014 personalized invitation of Czech citizens for cancer screening programs was launched to promote higher coverage by screening. The aim of the paper is to present the up-to-date results of the personalized invitation. The data from health insurance companies were used to evaluate the volume of invitations for cancer screening programs and the participation rate after invitation in 2014-2017. During the first four years of the project, over 6 million invitations were sent (approximately 3 million individuals were invited). Participation rates after the first invitation in the breast, colorectal and cervical screening were 22.3%, 21.7% and 15.5%. However, the effect of personalized invitations decreases with repeated invitations to participate. Personalized invitation contributed to screening in hundreds of thousands citizens, but a large proportion of invited people still do not participate. It is necessary to encourage personalized invitation and discuss other strategies to motivate the public to participate in screening programs.

Association of cancer prevention awareness with esophageal cancer screening participation rates: Results from a population-based cancer screening program in rural China.

OBJECTIVE: China have implemented population-based esophageal cancer (EC) screening programs, however, the participant rates were relatively low. This study was conducted to examine the association between cancer prevention knowledge and EC screening participation rates (PRs). METHODS: Data in the analyses were obtained from a population-based cancer screening program in four provinces in China since 2007. In the course of 2007-2016, participants who were evaluated as high risk for EC and subsequently recommended for endoscopy examination were included in the final analysis. One-way analysis of variance test, Chi-square test and logistic regression analysis were applied. RESULTS: A total of 28,543 individuals assessed as high-risk population for EC were included in this study, with 13,036 males (45.67%) and 15,507 females (54.33%). The prevalence rates of current smoking and alcohol drinking were higher in males (58.25% and 44.22%, respectively) than in females (5.35% and 4.05%, respectively). Participants of females, and those who had older age, lower income, as well as higher education level and cancer prevention knowledge level were more likely to undergo endoscopy. Multivariable analysis showed that higher cancer prevention knowledge was associated with higher PR for endoscopic screening [adjusted odd ratio (aOR Q4/Q1 ) =1.511, 95% confidence interval (95% CI): 1.398-1.632] among our study subjects. This association between cancer prevention knowledge and compliance with endoscopic screening also tends to be strong within subgroups of males, females, aged below 60 years, aged 60 years and above, and lower level of education (illiterate individuals and those with junior high education or less). CONCLUSIONS: Our results displayed a positive relationship between cancer prevention knowledge and PRs for endoscopic screening, implying cancer prevention awareness being an independent influence factor for compliance with EC screening. Promoting public campaigns about comprehensive knowledge of cancer prevention seemed to be a reasonable and effective strategy to improve population PRs for EC screening.
