Determinants of the demand for breast cancer screening among women veterans in the United States

Breast Cancer and Women Veterans: What Is the Impact of Mental Health on Screening Rates?

Background: The proportion of women Veterans are increasing and, as such, access to high-quality breast cancer care is important. Prior studies have shown that rural location, age, and a mental health diagnosis negatively impact breast cancer screening rates. Methods: We aimed to retrospectively assess the impact of these risk factors on breast cancer screening adherence rates among Veterans at our institution. Women who were eligible for breast cancer screening per the United States Preventative Services Taskforce guidelines were included. Results: Of 2321 women, overall adherence was 78.2%. There were no significant differences in screening rates between races, various age groups, geographical distribution, and having anxiety or post-traumatic stress disorder (PTSD). However, Veterans with a diagnosis of depression were more likely to adhere to screening guidelines. Having multiple mental health diagnoses was also not a negative risk factor. Conclusions: Our Veteran population's adherence rates are higher than the national average and rural location, race, age, and certain mental health disorders did not negatively affect adherence to screening mammography. Though more research is needed, screening reminders from our women's health coordinator may have improved adherence rates and lowered disparities.

Determinants of Compliance for Breast and Cervical Cancers Screening among Female Police Personnel of Mumbai, India—A Cross-Sectional Study

Introduction Women working in police force have unique and vital role to play in law enforcement. Although these women have established a secured place for themselves in the police force, they are exposed to several behavioral and health risks apart from job stress. All these can have potentially serious consequences on their well-being.

Objectives To determine the compliance to breast and uterine cervical cancers screening and identify predictors of participation in breast and cervical cancers screening among women police personnel.

Materials and Methods This is a cross-sectional study conducted among the Mumbai police personnel during the period 2019 to 2021. All women working for Mumbai police work force in 12 zones were invited to participate in the study. Temporary clinics for screening were set up in different police stations and eligible participants were enrolled after obtaining written informed consent. This was followed by sociodemographic and risk factor assessment, health education program, screening for common cancers conducted by trained primary health workers (breast by clinical breast examination and uterine cervix by visual inspection with 5% acetic acid). Screen positives were referred according to predefined referral criteria for further investigations and management.

Results A total of 3,017 police women were contacted, among them, 2,629 (87.14%) were eligible for screening, 2,609 (99.24%) participated in health education, and 1,839 (69.95%) complied for breast or cervical cancer screening. Further, compliance for screening of breast and uterine cervix were 1,837 (91.67%) and 1,297 (64.72%). A total of 256 (13.94%) and 217 (11.81%) police women were screen positives for breast and cervical cancers. According to multivariate logistic regression analysis, women younger than 50 years, those who were not married or were widowed or separated, postmenopausal women, and those who did not have shift duties had higher compliance for breast and cervix cancers screening.

Conclusion Good participation for breast and cervical cancers screening was seen among the women police personnel. This study has demonstrated that awareness and screening by simple low-cost methods for breast and cervical cancers screening is easily implementable and can be replicated among the women police force in different states of India.

Prediction of Pancreatic Cancer in Diabetes Patients with Worsening Glycemic Control

BACKGROUND

Worsening glycemic control indicates elevated risk of pancreatic ductal adenocarcinoma (PDAC). We developed prediction models for PDAC among those with worsening glycemic control after diabetes diagnosis.

METHODS

In 2000-2016 records within the Veterans Affairs Health System (VA), we identified three cohorts with progression of diabetes: (i) insulin initiation (n = 449,685), (ii) initiation of combination oral hypoglycemic medication (n = 414,460), and (iii) hemoglobin A1c (HbA1c) ≥8% with ≥Δ1% within 15 months (n = 593,401). We computed 12-, 36-, and 60-month incidence of PDAC and developed prediction models separately for males and females, with consideration of >30 demographic, behavioral, clinical, and laboratory variables. Models were selected to optimize Akaike's Information Criterion, and performance for predicting 12-, 36-, and 60-month incident PDAC was evaluated by bootstrap.

RESULTS

Incidence of PDAC was highest for insulin initiators and greater in males than in females. Optimism-corrected c-indices of the models for predicting 36-month incidence of PDAC in the male population were: (i) 0.72, (ii) 0.70, and (iii) 0.71, respectively. Models performed better for predicting 12-month incident PDAC [c-index (i) 0.78, (ii) 0.73, (iii) 0.76 for males], and worse for predicting 60-month incident PDAC [c-index (i) 0.69, (ii) 0.67, (iii) 0.68 for males]. Model performance was lower among females. For subjects whose model-predicted 36-month PDAC risks were ≥1%, the observed incidences were (i) 1.9%, (ii) 2.2%, and (iii) 1.8%.

CONCLUSIONS

Sex-specific models for PDAC can estimate risk of PDAC at the time of progression of diabetes.

IMPACT

Our models can identify diabetes patients who would benefit from PDAC screening.

Cancer Screening Among Current and Former U.S. Military Personnel Compared to Civilians: A Cross-Sectional Analysis of the Behavioral Risk Factor Surveillance System

INTRODUCTION

Approximately 3% of invasive U.S. cancer diagnoses are made among veterans in a Veterans Affairs (VA) clinic each year, while VA patients only comprise about 1.9% of the U.S. population. Although some research has shown that veterans have higher incidence rates of cancer compared to civilians, evidence is sparse regarding possible disparities in rates of cancer screening between these populations. Thus, the purpose of this study is to compare differences in rates of screening for colorectal, lung, breast, and cervical cancers between current and former U.S. Military service members and civilians.

METHODS

Using the data extracted from the Behavioral Risk Factor Surveillance System, we assessed the rates of cancer screening among current and former U.S. Military service members compared to civilians from self-reported surveys assessing when individuals had been screened for colorectal or lung cancer among all participants and breast and cervical cancer among women participants. Persons greater than 25 years of age were included in the cervical cancer screening, 50 years of age for colon cancer screening, and 40 years of age for the breast cancer screening-the latter based on recommendations from the American Cancer Society. We used multivariate logistic regression models to determine the adjusted risk ratios (ARRs) of current and former U.S. Military service members receiving screening compared to civilians, adjusting for age, gender, race, education, and health care coverage.

RESULTS

Current and former U.S. Military service members accounted for 2.6% of individuals included for the cervical cancer screening analysis, 2.2% for the breast cancer screening analyses, nearly 10% of the lung cancer screening, and 15% of the colorectal cancer (CRC) screening analyses. Prevalence of screening was higher for current and former U.S. Military service members among lung cancer and CRC. When controlling for age, race, education, and health care coverage, current and former U.S. Military service members were statistically more likely to be screened for CRC (ARR: 1.05; 95% confidence interval: 1.04-1.07) and lung cancer (ARR: 1.32; 95% confidence interval: 1.15-1.52). The odds of having completed a cervical or breast cancer screening were not significantly different between groups.

CONCLUSION

Our study showed that current and former U.S. Military service members were more likely to complete CRC and lung cancer screenings, while no significant difference existed between each population with regard to cervical and breast cancer screenings. This is one of the few studies that have directly compared cancer screening usage among civilians and current and former U.S. Military service members. Although current and former U.S. Military service members were more likely to receive several cancer screenings, improvements can still be made to remove barriers and increase screening usage due to the disproportionate rates of cancer mortality in this population. These solutions should be comprehensive-addressing personal, organizational, and societal barriers-to improve prognosis and survival rates among current and former U.S. Military service members.

Determinants Associated With Longitudinal Adherence to Annual Lung Cancer Screening: A Retrospective Analysis of Claims Data

OBJECTIVE

Lung cancer screening (LCS) efficacy is highly dependent on adherence to annual screening, but little is known about real-world adherence determinants. We used insurance claims data to examine associations between LCS annual adherence and demographic, comorbidity, health care usage, and geographic factors.

MATERIALS AND METHODS

Insurance claims data for all individuals with an LCS low-dose CT scan were obtained from the Colorado All Payer Claims Dataset. Adherence was defined as a second claim for a screening CT 10 to 18 months after the index claim. Cox proportional hazards regression was used to define the relationship between annual adherence and age, gender, insurance type, residence location, outpatient health care usage, and comorbidity burden.

RESULTS

After exclusions, the final data set consisted of 9,056 records with 3,072 adherent, 3,570 nonadherent, and 2,414 censored (unclassifiable) individuals. Less adherence was associated with ages 55 to 59 (hazard ratio [HR] = 0.80, 99% confidence interval [CI] = 0.67-0.94), 60 to 64 (HR = 0.83, 99% CI = 0.71-0.97), and 75 to 79 (HR = 0.79, 99% CI = 0.65-0.97); rural residence (HR = 0.56, 99% CI = 0.43-0.73); Medicare fee-for-service (HR = 0.45, 99% CI = 0.39-0.51), and Medicaid (HR = 0.50, 99% CI = 0.40-0.62). A significant interaction between outpatient health care usage and comorbidity was also observed. Increased outpatient usage was associated with increased adherence and was most pronounced for individuals without comorbidities.

CONCLUSIONS

This population-based description of LCS adherence determinants provides insight into populations that might benefit from specific interventions targeted toward improving adherence and maximizing LCS benefit. Quantifying population-based adherence rates and understanding factors associated with annual adherence are critical to improving screening adherence and reducing lung cancer death.

Ethnic Differences in Participation in Medical Check-ups Among the Elderly: Evidence from Malaysia

BACKGROUND

There were ethnic differences in the prevalence of non-communicable diseases among the elderly in Malaysia.

OBJECTIVE

To examine ethnic differences in participation in medical check-ups among the elderly.

DESIGN

A nationally representative data set was employed. Multiple logistic regressions were utilised to examine the relationship between ethnicity and the likelihood of undergoing medical check-ups. The regressions were stratified by age, income, marital status, gender, household location, insurance access and health status. These variables were also controlled for in the regressions (including stratified regressions).

PARTICIPANTS

The respondents were required to be residents of Malaysia and not be institutionalised. Overall, 30,806 individuals were selected to be interviewed, but only 28,650 were actually interviewed, equivalent to a 93% response rate. Of those, only 2248 were used in the analyses, because 26,402 were others or below aged 60.

MAIN MEASURES

The dependent variable was participation in a medical check-up. The main independent variables were the three major ethnic groups in Malaysia (Malay, Chinese, Indian).

KEY RESULTS

Among the elderly aged 70-79 years, Chinese (aOR 1.89; 95% CI 1.28, 2.81) and Indians (aOR 2.39; 95% CI 1.20, 4.74) were more likely to undergo medical check-ups than Malays. Among the elderly with monthly incomes of ≤ RM999, Chinese (aOR 1.44; 95% CI 1.12, 1.85) and Indians (aOR 1.50; 95% CI 0.99, 2.28) were more likely to undergo medical check-ups than Malays. Indian males were more likely to undergo medical check-ups than Malay males (aOR 2.32; 95% CI 1.15, 4.67). Chinese with hypercholesterolaemia (aOR 1.45; 95% CI 1.07, 1.98) and hypertension (aOR 1.32; 95% CI 1.02, 1.72) were more likely to undergo medical check-ups than Malays.

CONCLUSIONS

There were ethnic differences in participation in medical check-ups among the elderly. These ethnic differences varied across age, income, marital status, gender, household location, insurance access and health status.

What Explains Education Disparities in Screening Mammography in the United States? A Comparison with The Netherlands

Background: In the U.S., less educated women are substantially less likely to receive screening mammography. It is not clear whether this is due to differences in access to screening or in perceptions of breast cancer risks and the effectiveness of screening. We weigh the plausibility of these two explanations by examining how the dependence of mammography on education changes after conditioning on indicators of access and perceptions. We also compare estimates for the U.S. with those for the Netherlands where there is universal access to a publicly financed screening program. Method: Cross-sectional and cross-country comparable individual level data from the American Life Panel (n = 646) and the Netherlands Longitudinal Internet Studies for the Social Sciences (n = 1398) were used to estimate and explain education disparities in screening mammograms given to American and Dutch women aged 40+. The education gradient was estimated using logit models. Controls were sequentially added to detect whether disparities were explained by differences in access or perceptions of risks and effectiveness. Results: In the United States, high school graduates were 11.5 percentage points (95% CI: 1–22 percentage points) less likely than college graduates to receive a screening mammogram in the previous two years. This education gradient was largely explained by differences in income, insurance coverage and receipt of medical advice. It was not explained by educational differences in the perceived risk of breast cancer and the effectiveness of mammography. There were no education disparities in receipt of mammography among Dutch women within the 50–75 age range covered by the national screening program. Conclusion: In the absence of a universal screening program in the U.S., determinants of access—income, insurance coverage and receipt of medical advice—appear to drive the education disparities in screening mammography.

Blood pressure and cholesterol level checks as dynamic interrelated screening examinations

This study analysed the determinants of screening uptake for blood pressure and cholesterol level checks. Furthermore, it investigated the presence of possible spillover effects from one type of cardiovascular screening to another type of cardiovascular screening. A dynamic random effects bivariate panel probit model with initial conditions (Wooldridge-type estimator) was adopted for the estimation. The outcome variables were the participation in blood pressure and cholesterol level checks by individuals in a given year. The balanced panel sample of 21,138 observations was constructed from 1,626 individuals from the British Household Panel Survey (BHPS) between 1996 and 2008. The analysis showed the significance of past screening behaviour for both cardiovascular screening examinations. For both cardiovascular screening examinations state dependence exist. The study also shows a significant spillover effect of the cholesterol level check on the blood pressure check and vice versa. Also a poorer health status led to a higher uptake for both types of screening examinations. Changes in recommendations have to consider the fact that taking part in one type of cardiovascular screening examination can influence the decision to take part in the other type of cardiovascular screening examination.

Determinants of a GP visit and cervical cancer screening examination in Great Britain

OBJECTIVE

In the UK, women are requested to attend a cervical cancer test every 3 years as part of the NHS Cervical Screening Programme. This analysis compares the determinants of a cervical cancer screening examination with the determinants of a GP visit in the same year and investigates if cervical cancer screening participation is more likely for women who visit their GP.

METHODS

A recursive probit model was used to analyse the determinants of GP visits and cervical cancer screening examinations. GP visits were considered to be endogenous in the cervical cancer screening examination. The analysed sample consisted of 52,551 observations from 8,386 women of the British Household Panel Survey.

RESULTS

The analysis showed that a higher education level and a worsening self-perceived health status increased the probability of a GP visit, whereas smoking decreased the probability of a GP visit. GP visits enhanced the uptake of a cervical cancer screening examination in the same period. The only variables which had the same positive effect on both dependent variables were higher education and living with a partner. The probability of a cervical cancer screening examination increased also with previous cervical cancer screening examinations and being in the recommended age groups. All other variables had different results for the uptake of a GP visit or a cervical cancer screening examination.

CONCLUSIONS

Most of the determinants of visiting a GP and cervical cancer screening examination differ from each other and a GP visit enhances the uptake of a smear test.

Breast and cervical cancer-screening uptake among females in Ardabil, northwest Iran: a community-based study

PURPOSE

Breast and cervical cancers are the most commonly diagnosed type of cancer and cause of cancer-related deaths in Iranian females. In contrast to previous studies, this study was carried out with a large sample size for assessment of breast self-examination (BSE)-, clinical breast examination (CBE)-, mammography-, and Pap smear-uptake rates and determination of associations among these screening behaviors with sociodemographic and cognitive variables in Azeri females.

MATERIALS AND METHODS

This was a cross-sectional, community-based study that was carried out among 1,134 females 20-60 years old during March-June 2016. Data-collection variables included sociodemographic questions, screening behaviors for breast and cervical cancer, self-efficacy, beliefs, and barriers to breast and cervical cancer screening. Collected data were analyzed by SPSS version 13 using χ2, Mann-Whitney U, and logistic regression tests.

RESULTS

Among the 1,134 participants, 53.9%, 9.8%, and 28.1% had done BSE, CBE, and Pap smear tests, respectively, and among the 625 females aged >40 years, 187 (29.9%) had done the mammography test. Moreover, 416 (36.7%), 103 (16.5%), and 64 (5.6%) females had done BSE, mammography, and CBE regularly, respectively. Beliefs, barriers, income, health insurance, number of children, and age were all important factors for BSE and regular BSE and mammography. Females who had high belief scores were more likely to undertake mammography (odds ratio [OR]: 1.2, 95% confidence interval [CI]: 1.03-1.5), regular mammography (OR: 4.2, 95% CI: 1.9-9.3), regular CBE (OR: 1.25, 95% CI: 1.2-1.3), and Pap smears (OR: 1.2, 95% CI: 1.1-1.4). Also, females who had high self-efficacy scores were more likely to perform regular BSE (OR: 1.8, 95% CI: 1.4-2.5) and mammography (OR: 2.5, 95% CI: 1.4-4.6) than females with lower self-efficacy scores.

CONCLUSION

The frequency of breast and cervical cancer screening was low in our study. The findings of this study indicated that beliefs, self-efficacy, and barriers were important predictive factors of cancer-screening behavior among the females studied.

Socioeconomic and lifestyle determinants of blood glucose screening in Malaysia

Background

The increase in prevalence of diabetes is a serious public health issue. It is well-documented that use of blood glucose screening can help to reduce the risk of developing diabetes.

Objectives

To examine the socioeconomic and lifestyle factors associated with use of blood glucose screening among Malaysian adults.

Methods

Nationally representative data from 2,415 survey respondents was used. The survey was a cross-sectional population-based study previously conducted by the Ministry of Health Malaysia. A logistic regression model was developed to estimate the likelihood of using blood glucose screening.

Results

Age, marital status, ethnicity, income, smoking, and body mass index were significantly associated with use of blood glucose screening. In particular, older individuals, married individuals, Malays, higher income earners, non-smokers, and being obese, overweight or of normal weight were correlated with a higher likelihood of using blood glucose screening.

Conclusions

It is important to acquire a better knowledge of the factors that can influence the decision of people to adopt preventive measures. Having better information regarding which groups of individuals use or do not use blood glucose screening can assist governments in developing appropriate intervention programs.

Blood glucose screening among elderly Malaysians: Who to target?

BACKGROUND

Early detection of raised blood glucose can reduce the risk of developing diabetes. Despite being a high-risk group, a significant proportion of the elderly population does not undergo blood glucose screening. The aim of the present study was to examine the factors affecting blood glucose screening among the elderly.

METHODS

Data from a sample of 2463 respondents in the National Health and Morbidity Survey 2011 were used. Pearson Chi-squared tests were conducted to find factors associated with screening behavior. A logit model was used to analyze the likelihood of screening.

RESULTS

Income, age, education, ethnicity, employment status, availability of medical coverage, and smoking behavior were significantly associated with blood glucose screening. The likelihood of blood glucose screening was positively correlated with available monthly income and was higher in those aged 60-69 years, those attaining higher education, Malays, and elderly who are medically covered.

CONCLUSIONS

The findings of the present study provide insights for health policy formulation for the elderly. As part of their efforts to reduce national health costs, governments should pay particular attention to the elderly, who are likely to be unscreened for blood glucose levels, because they face even larger risk exposure.

Health Shocks and Initiation of Use of Preventive Services Among Older Adults

This article examines whether adverse changes to health or functioning serve as an impetus to begin using preventive services among older individuals with a history of non-use. Using data from the 1998-2008 Health and Retirement Study, the use of mammograms, pap smears, prostate cancer screenings, cholesterol checks, and flu shots is examined among 2,975 self-reported non-users of such services. Older women who experience a health shock are 1.86, 1.50, 1.79, and 1.46 times more likely to begin getting mammograms, pap smears, cholesterol checks, and flu shots, respectively. Older men who experience a health shock are 2.24, 2.72, and 1.64 times more likely to begin getting prostate cancer screenings, cholesterol checks, and flu shots, respectively. All of these results are statistically significant. Thus, older adults often improve their health behaviors after experiencing an adverse health event.

Breast and cervical cancer screening in Great Britain: Dynamic interrelated processes

No previous analysis has investigated the determinants of screening uptake for breast and cervical cancer screening for possible spillover effects from one type of screening examination to the other type of screening examination with a dynamic bivariate panel probit model. For our analysis, we used a dynamic random effects bivariate panel probit model with initial conditions (Wooldridge-type estimator) and dependent variables were the participation of breast and cervical cancer screening in the recent year. The balanced panel sample consisted of 844 women from the British Household Panel Survey (BHPS) from the time period 1992 to 2008. Our analysis showed the high relevance of past screening behaviour and the importance of state dependency for the same and the other type of cancer screening examinations even after controlling for covariates and unobserved heterogeneity. The uptake for breast and cervical cancer screening was higher when the same screening examination was done one or three years earlier. This result is in accordance with the medical screening programmes in Great Britain. With regard to breast and cervical cancer screening positive spillover effects existed between screening examinations in the third order lags. Women with a previous visit to a general practitioner and individuals in the recommended age groups had a higher uptake for breast and cervical cancer screening. Other socioeconomic and health related variables had non-uniform results in both screening examinations. Promoting the uptake of one female prevention activity could also enhance the uptake of the other prevention activity.

A Critique of Grossman's Canonical Model of Health Capital

In the health economics literature, the demand for health and market health inputs is dominated by adaptations of Grossman's health capital model. The model has been widely used to explore a wide range of issues related to health, socioeconomic inequalities in health, demand for medical care, health preventions, occupational choice, and retirement decisions. The commodity of health is viewed as a durable capital stock that yields a flow of healthy time or illness-free time, that depreciates with age, and that can be augmented with the help of market health inputs and own time. The purpose of this article is to provide a comprehensive critical review of the model. Underlying Grossman's model are a faulty conceptual framework and assumptions that tend to exaggerate the degree of control consumers/patients may have over their state of health and survival. The assumption of full information about one's state of health and the efficacy of various health inputs abstracts away from the problems posed by the agency relationship under uncertainty and informational asymmetry. Grossman's individualistic and mechanistic view of health strips health capital and its production of much of their biological/physiological content and their interactions with the individual's social and physical environment.

Improving care of chronic conditions for women veterans: identifying opportunities for comparative effectiveness research

This article aims to critically analyze research focused on the findings for five chronic conditions: chronic pain, diabetes, cardiovascular disease, HIV and cancer among women veterans to identify opportunities for comparative effectiveness research. We provide a descriptive analysis from the relevant articles in prior systematic reviews. In order to identify potential gaps in research for these specific conditions, we also conducted a literature search to highlight studies focusing on women veterans published since the last systematic review. While the scientific knowledge base has grown for these chronic conditions among women veterans, the vast majority of the published literature remains descriptive and/or observational, with only a few studies examining gender differences and even fewer clinical trials. There is a need to conduct comparative effectiveness research on chronic conditions among women veterans to improve health and healthcare.

Explaining variations in breast cancer screening across European countries

OBJECTIVE

In this study I aim to explore the statistical causes of country differences in mammography screening among women aged 50-69 years in 13 European countries. I focus on the relative importance of individual (e.g. age, education, etc.) and institutional (e.g. public screening programmes) factors in explaining these differences.

DATA AND METHODS

I use individual level data from the first three waves (2004-2006-2009) of the SHARE as well as regional and country level data on institutional factors. The analytical approach is based on multilevel statistical models, which allow me to analyse the contribution of individual and institutional factors in explaining the variation in breast cancer screening across European countries.

RESULTS

I find that the standard deviation in screening rates across countries increases slightly from 19.5 to 20.8 per cent after controlling for individual factors. Observed individual factors such as age, education, health status, etc., do not significantly contribute to the explanation of cross-country differences. In contrast, after controlling for observed institutional factors such as the availability of an organised screening programme, the standard deviation drops from 20.86 to 12.92 per cent. These factors can statistically explain about 40 per cent of the between-country differences in screening rates. Moreover, I found that these institutional factors seem to prevent a woman from considering a mammogram "not necessary".

CONCLUSION

This analysis provides important insights about patient's attitudes and understanding of benefits of breast cancer prevention and highlights the importance of the availability of an organised screening programme for screening differences across European countries.

Female preventive practices: breast and smear tests

Breast cancer and cervical cancer are the most common female cancers in Spain and in many developed countries. The main goal of this paper is to identify the determinants of individual decisions on breast screening and smear testing, that is to say, the decision to take a test for the first time and the decision to test with suitable regularity. To that end, we have combined analyses of micro and macro data (the Spanish National Health Survey and Spanish Regional Social Indicators) and employed multilevel estimation models. Among the main results, we highlight the fact that regional public screening programmes improve individual decisions on screening (more women testing for the first time and more women testing regularly) and, furthermore, they generate positive synergies; for example, regional public programmes for smear testing improve individual decisions on both cervical and breast cancer screening. In addition, we conclude that it is not only important to know if the numbers of women undergoing breast screening and smear testing are increasing, it is also important to know if they are testing regularly.

Cervical cancer screening service utilisation in UK

This study investigates empirically how past screening behaviour, individual and household characteristics affect the current uptake of cervical cancer screening in UK. For the conceptual framework, we use a modified Grossman model which is extended for non-economic factors. A dynamic version of a random effects panel probit model with initial conditions is estimated on the balanced sub-sample of the data. The analysis sample is restricted to women of age 16 and older and grouped into different age categories with respect to the NHS Cervical Screening Programme (NHSCSP). As dataset a balanced panel data of 857 women with 11,998 observations from the British Household Panel Study (BHPS) for the period from 1992 to 2008 is used for the analysis. Results suggest show that previous screening uptake, age, partner status, employment status and a previous GP visit have a significant influence on the likelihood of the uptake of cervical cancer screening.

Preventive care use among the Belgian elderly population: does socio-economic status matter?

OBJECTIVE

To analyze the association between influenza and pneumococcus vaccination and blood cholesterol and blood sugar measurement by Belgian elderly respondents (≥ 65 years) and socio-demographic characteristics, risk factors, health status and socio-economic status (SES).

METHODS

A cross-sectional study based on 4,544 non-institutionalized elderly participants of the Belgian Health Interview Surveys 2004 and 2008. Multivariate logistic regression models were constructed to examine the independent effect of socio-demographic characteristics, risk factors, health status and SES on the four preventive services.

RESULTS

After adjustment for age, sex, region, survey year, living situation, risk factors (body mass index, smoking status, physical activity) and health status (self-assessed health and longstanding illness) lower educated elderly were significantly less likely to report a blood cholesterol and blood sugar measurement. For instance, elderly participants with no degree or only primary education were less likely to have had a cholesterol and blood sugar measurement compared with those with higher education. Pneumococcus vaccination was not related to educational level, but lower income groups were more likely to have had a pneumococcus immunization. Influenza vaccination was not significantly related to SES.

CONCLUSION

The results highlight the need to promote cholesterol and blood sugar measurement for lower SE groups, and pneumococcus immunization for the entire elderly population. Influenza immunization seems to be equally spread among different SE groups.

Utilisation of preventative health check-ups in the UK: findings from individual-level repeated cross-sectional data from 1992 to 2008

OBJECTIVES

To analyse and compare the determinants of screening uptake for different National Health Service (NHS) health check-ups in the UK.

DESIGN

Individual-level analysis of repeated cross-sectional surveys with balanced panel data.

SETTING

The UK.

PARTICIPANTS

Individuals taking part in the British Household Panel Survey (BHPS), 1992-2008.

OUTCOME MEASURE

Uptake of NHS health check-ups for cervical cancer screening, breast cancer screening, blood pressure checks, cholesterol tests, dental screening and eyesight tests.

METHODS

Dynamic panel data models (random effects panel probit with initial conditions).

RESULTS

Having had a health check-up 1 year before, and previously in accordance with the recommended schedule, was associated with higher uptake of health check-ups. Individuals who visited a general practitioner (GP) had a significantly higher uptake in 5 of the 6 health check-ups. Uptake was highest in the recommended age group for breast and cervical cancer screening. For all health check-ups, age had a non-linear relationship. Lower self-rated health status was associated with increased uptake of blood pressure checks and cholesterol tests; smoking was associated with decreased uptake of 4 health check-ups. The effects of socioeconomic variables differed for the different health check-ups. Ethnicity did not have a significant influence on any health check-up. Permanent household income had an influence only on eyesight tests and dental screening.

CONCLUSIONS

Common determinants for having health check-ups are age, screening history and a GP visit. Policy interventions to increase uptake should consider the central role of the GP in promoting screening examinations and in preserving a high level of uptake. Possible economic barriers to access for prevention exist for dental screening and eyesight tests, and could be a target for policy intervention.

TRIAL REGISTRATION

This observational study was not registered.

Who gets a mammogram amongst European women aged 50-69 years?

On the basis of the Survey of Health, Ageing, and Retirement (SHARE), we analyse the determinants of who engages in mammography screening focusing on European women aged 50-69 years. A special emphasis is put on the measurement error of subjective life expectancy and on the measurement and impact of physician quality. Our main findings are that physician quality, better education, having a partner, younger age and better health are associated with higher rates of receipt. The impact of subjective life expectancy on screening decision substantially increases after taking measurement error into account.

Factors influencing the intention to utilize out-of-pocket health checkup services: A sample of citizens from 12 townships of Taichung County in Taiwan

BACKGROUND

Taiwan started its National Health Insurance (NHI) system in 1995. However, until now, most cancer screening tests and preventive care have been out-of-pocket (OOP) medical items excluded from the coverage of NHI. The aim of this study was to explore the factors influencing an individual's intention to utilize OOP health checkups.

METHODS

A cross-sectional research method was adopted in this study. Based on the theory of planned behavior, a questionnaire was developed and used to survey purposively sampled residents (n = 940) from 12 randomly selected townships in Taichung County, Taiwan, from August to September 2006. Descriptive statics and linear regression were conducted to analyze the collected data.

RESULTS

Our results showed that result evaluation (beta = 0.092), behavioral beliefs (beta = 0.088), behavioral norms of people with experience in utilizing OOP health checkups (beta = 0.116), perceived convenience (beta = 0.273), and worry about illness and perceived health (beta = 0.110) were important factors influencing the intention to utilize OOP health checkups. Age, education and acceptable health checkup charges were also related.

CONCLUSION

Reinforcing disease- and health checkup-related knowledge may positively influence an individual's intention to utilize OOP health checkups. In addition, improving perceived convenience and reducing disease-screening barriers can intensify the individual's intention to use OOP health checkups. The influence of age, education level and OOP checkup charges should also be taken into consideration when related policies are formulated.

[Prevalence of non-utilization of mammography and associated factors in elderly women]

This study analyzes the prevalence of non-utilization of mammography among older women, according to socio-demographic variables, health status, and use of preventive health services. This was a cross-sectional study including women 60 years or older. We interviewed 4,621 women 60 to 106 years of age; the majority were widows (51.8%) and had little or no schooling (53.8%). Most (89%) reported health problems, and 66.4% used private medical care. Prevalence of self-reported mammography was 72.1%. Gynecological visits (PR = 2.39; 95%CI: 2.04-2.80), Pap smear (PR = 3.24; 95%CI: 2.89-3.63), years of schooling (PR = 1.07; 95%CI: 1.02-1.12), health care insurance (PR = 1.16; 95%CI: 1.11-1.20), physician visits (PR = 1.23; 95%CI: 1.11-1.37), age (PR = 1.12; 95%CI: 1.08-1.17), marital status (PR = 1.05; 95%CI: 1.00-1.09), and barriers to health services (PR = 0.94; 95%CI: 0.89-0.98) were also associated with non-utilization of mammography. These associations may be partially explained by lack of knowledge, poor access to public health services, and cultural factors related to the aging process and reproductive incapacity.

Factors influencing the uptake of screening services for breast and cervical cancer in Taiwan

AIMS

Cervical cancer and breast cancer have had the first and second highest occurrence rates among women in Taiwan since 1981 and have also been two of the leading causes of cancer death. In order to more effectively promote preventive medical care programs, it is important to identify the key determinants of women's behavior regarding their decisions to engage in screenings. This study aims to identify the major factors that affect the utilization of breast and cervical cancer screening among women in Taiwan, who are covered by universal National Health Insurance.

METHODS

Data were obtained from the 2001 National Health Interview Survey for the Taiwan area and targeted women between 30 and 75 years old. The sample size consisted of 5,611 individuals for Papanicolaou (Pap) tests and breast examinations by a doctor. For breast ultrasounds and mammograms, 3,875 individuals were included. The propensity among women in Taiwan to use the two types of screening services, i.e., Pap test and breast examinations, were estimated by maximum likelihood probit regressions.

RESULTS

The findings in this study show that the likelihood of a woman receiving a Pap test or a clinical breast examination depends on a variety of factors such as age, marital status, income level, education, and health status. Women with lower socioeconomic status were found to be much less likely to undergo the freely available cancer screening services. In addition, healthy behavior, such as not smoking and engaging in exercise, had a positive effect on the uptake of screening.

CONCLUSIONS

The results of this study enable us to understand more thoroughly the characteristics of women who undergo a Pap test and breast examination, as well as the factors that influence them in Taiwan. The findings can help formulate related policies that are directed at removing the barriers to accessing medical care and targeting those at-risk groups. This analysis provides new evidence of the factors affecting the utilization of preventive care among women in a developing country, which are comparable to those of other countries, and may shed further light on the issue of promoting cancer screening and women's health.

Fatores associados à realização de exames preventivos para câncer nas mulheres brasileiras, PNAD 2003

Estudar fatores associados à realização dos exames Papanicolaou e mamografia por mulheres brasileiras. Foram analisadas informações sobre mulheres com 25 anos ou mais, no suplemento Saúde da Pesquisa Nacional de Amostras Domiciliares (PNAD) do IBGE 2003, de realização de Papanicolaou nos últimos 5 anos e mamografia nos últimos 2 anos, sua prevalência por variáveis demográficas, socioeconômicas e saúde, acesso e utilização de serviços de saúde. Foram realizadas análise estatística bivariada e regressão logística para os dois procedimentos. A prevalência para Papanicolaou foi 75,5% e mamografia 36,1%. A regressão logística mostrou como principais fatores preditivos para Papanicolaou: ter filhos, consulta médica no último ano, renda elevada, médio a alto grau de escolaridade, ter plano de saúde e morar em zona urbana. Para mamografia mostraram-se fatores preditivos importantes: distribuição etária (40-59 anos), consulta médica no último ano, morar em zona urbana, renda elevada e ter plano de saúde. No Papanicolaou há maior incorporação na assistência, e o acesso à consulta médica fator essencial para a realização do exame. Na mamografia, a prevalência é mais elevada nas faixas etárias recomendadas, perfil diferenciado por acesso à consulta médica e condição socioeconômica, e muitos exames em mulheres em faixas etárias não recomendadas.
