Prevalence and correlates of recent and repeat mammography among California women ages 55-79

Status of the utilization of preventive care services and its associated socio-demographic factors among Iranian elderly

Introduction

The growing population of the elderly, the rising costs of medical care and the low use of preventive services are three factors that highlight the importance of using preventive health care services in the Iranian population. This study aimed to determine the status of the use of preventive care services and its associated socio-demographic factors in the elderly referred to health centers.

Methods

In this analytical cross-sectional study, a number of 160 elderly people referred to health centers in East Guilan, Iran was selected by multi-stage cluster sampling. Data were obtained from May to September, 2021 using a questionnaire containing utilization of preventive care services (9 items) and socio-demographic characteristics.

Results

The highest and the lowest utilization rates of preventive care services among study participants were related to the blood pressure test (96.9%) and colonoscopy (17.5%), respectively. Multivariate analysis showed that only income had a significant association with performing fasting blood sugar test (p = 0.004), blood lipid test (p = 0.004), and blood pressure test (p = 0.013). Also, the associations between having an underlying disease and performing fasting blood sugar test (p = 0.032) and blood pressure test (p = 0.002), the association between gender and performing the bone mineral density test (p < 0.001), and the association between occupation and performing Pap-smear test (p = 0.011), were statistically significant.

Conclusions

The utilization rates of screening tests for most cancers, including gastrointestinal cancers, were low. Since, there were a significant association between income, disease, gender and occupation with the utilization of some preventive care services, considering them in health centers' preventive care program design might be useful.

Determinants of mammography screening in Iranian women: A systematic review and meta-analysis

BACKGROUND

Mammography is the most effective method for early detection of breast cancer (BC), however, it has performed in low-level. The aim of this study was to investigate the determinants of mammography in Iran.

METHODS

This study was a systematic review which was performed based on articles published in both Persian and English languages among Iranian patients in the period of 2000 to 2020 by using keywords of "Iran and mammography". Papers were selected from national databases including (SID, Magiran) and international database including (Scopus, PubMed and web of science), finally related articles to mammography were reviewed.

RESULTS

Findings indicated that 35-50% of breast cancer can be detected in the early stages by mammography, however, it is in low rate of performance among Iranian women. Age, age of menarche, occupation, family history, marital status, family support, number of pregnancies, physician recommendations, perceived sensibility and severity, self-efficacy and perceived benefits are the most important predictors of performing mammography in Iran.

CONCLUSION

Due to the growing trend of breast cancer cases in the country and low mammography rates in Iranian population, high risk groups such as women with BC family history, low income level, low education level, older age and people with history of breast complications were more emphasized for performing mammography through health centers. Therefore, appropriate planning to reduce the barriers of mammography could be helpful.

Comparing Telephone Counseling With Reminding to Promote On-Time Repeated Mammography: A Randomized Trial in a Cohort With 4 Years Follow-Up

Background. Long-term continuous adherence to biennial screening mammograms as guidelines recommend remains low. Limited evidence suggests that reminder calls may increase short-term adherence as much as telephone counseling, but research is needed comparing the long-term effects of these two approaches. Purpose. To compare the impacts of two telephone outreach interventions and mailed reminders on 4-year continuous mammography adherence. Method. A cohort of 3,215 women, age 50 to 81 years, was selected from 30,160 women from a 4-year randomized trial of three interventions to promote biennial mammography: reminder letter only (LO), letter plus reminder call (RC), and two letters plus educational material and a counseling call (CC). Women selected remained eligible for the trial all 4 years and received annual interventions as needed. The proportion with a mammogram in the last 24 months was determined at baseline and four annual time points. Results. Continuous adherence at all four time points was higher in the RC (78.8%) and CC arms (78.8%) than in the LO arm (75.1%; p < .001). Multivariable analysis confirmed this finding: CC (odds ratio = 1.27; 95% confidence interval = [1.01, 1.61]) and RC (odds ratio = 1.23; 95% confidence interval = [0.98, 1.56]). Only 27.8% of women eligible for an initial counseling call actually received counseling. Conclusions. Compared with letters alone, outreach calls can modestly increase continuous mammography adherence among insured women with consistent primary care. Telephone counseling was no more effective than a reminder call, possibly due to limited acceptance of counseling calls by women who may find them unwelcome or unnecessary.

Prevalence and Determinants of Repeat Mammography Among Women from a Developing Country

Failures in repeat mammography decrease the potential benefits of screening; however, it is notable that the recent use of mammography is more frequently studied than repeat use. We estimated the prevalence and analyzed determinants for repeat mammography among women from Mexico, a developing country of Latin America. It was a two-stage study with an initial cross-sectional design (n = 1045) and a final case-control design that involved women of at least 45 years of age with no history of breast, ovarian, or uterine cancer. Case subjects were those with three or more mammograms in the last 5 years, with the last one carried out within the last two years (n = 444); control subjects included those who underwent ≥3 mammograms throughout their life with the most recent carried out >2 years ago (n = 444). Through interviews, we evaluated context-dependency, fulfillment of expected outcomes, self-efficacy, and risk perception, among other factors. We estimated the prevalence with 95 % confidence intervals (CI), and odds ratios (OR) using multivariate binary logistic regression. The prevalence of repeat mammography was 40.4 % (95 % CI 37.4-43.4). Self-efficacy demonstrated the highest effect on repeat use (OR 7.7, 95 % CI 4.7-12.6), followed by awareness context-dependency (OR 4.9, 95 % CI 3.3-7.2), the use of Papanicolaou testing (OR 3.5, 95 % CI 2.3-5.2), the fulfillment of expected waiting time outcome (OR 2.4, 95 % CI 1.2-4.7), and context-dependency related to self-referral/health provider referral (OR 2.4, 95 % CI 1.7-3.4), independent of risk perception, age, education, and positive emotional state of mind. The study showed a need for increasing the prevalence of promoting awareness of the determining factors of repeat mammography, which is a necessary component in the early detection of breast cancer.

Disparities in mammography rate among immigrant and native-born women in the U.S.: progress and challenges

Disproportionately low mammography rates among U.S. immigrants have been of persistent concern. In light of policies to increase access to screening, this study identifies differences in factors associated with screening among immigrant and native-born women in 2000 and 2008. Data from immigrant and native-born women aged 40+ years in the 2000 and 2008 National Health Interview Surveys were included in descriptive and multivariate regression analyses. Mammography rates rose from 60.2 to 65.5 % among immigrant women, remaining lower than the 68.9 % rate among native-born in 2008. Among immigrants, short length of residency and lower education were associated with lower screening rates in 2000 but not in 2008, while public insurance coverage was positively associated with screening only in 2008. In contrast to immigrants, among the native-born education and income were associated with mammography receipt in 2008, and in both groups health care access was associated with greater screening rates. Policy initiatives aimed at increasing access to mammography may be positively affecting immigrant screening disparities. Access to primary care and public insurance coverage are likely to be very important in maintaining and furthering improvements in mammography rates.

Women with abnormal screening mammography lost to follow-up: An experience from Taiwan

Breast cancer has the highest incidence among all cancers for women in Taiwan. The current screening policy in Taiwan suggested a biennial mammography for all women 40 to 69 years of age. A recommendation for additional testing is recommended for women with a BI-RADS result of 0 or 4; a request made via postal mail. Approximately 20% of high-risk patients do not receive additional follow-up. Therefore, we aimed to explore the causes of these patients being lost to follow-up, despite an abnormal mammogram. Two questionnaires were designed separately according to the conceptual framework of the Health Belief Model. Study participants, women who received a screening mammography at the National Taiwan University Hospital in 2011 with a BI-RAD of 0 or 4, were interviewed via telephone. The dependent variable was receipt of follow-up or not. The analyses were performed by using χ tests and logistic regression models. In total, 528 women were enrolled in the study: 51.2% in BI-RADS 0 group and 56.6% in BI-RADS 4, respectively. In the BI-RADS 0 group, those patients who received a follow-up examination cited the most likely causes to be physician suggestion, health implications, and concerns regarding breast cancer. Patients who did not receive a follow-up examination cited a lack of time and a perception of good personal health as primary reasons. In the BI-RADS 4 group, those patients who received a follow-up examination cited the physician's recommendation and a recognition of the importance of follow-up examinations. Patients who did not receive a follow-up examination cited having received follow-up at another hospital and a desire for a second opinion. In the BI-RADS 0 group, multivariate analysis showed that patients with higher scores in the "perceived benefits" domain were statistically more likely to receive a follow-up examination. There was no significant difference in perceived threats, perceived barriers, action cues, or self-efficacy between groups. We conclude that additional education to raise breast cancer awareness in the general public and healthcare providers will be needed to improve the rate of follow-up examinations after an abnormal screening mammogram.

The relationship of social support concept and repeat mammography among Iranian women

BACKGROUND

Breast cancer ranks as the first most common cancer among the Iranian women. The regular repeat of mammography with 1-2 year intervals leads to the increased efficiency of early detection of breast cancer. The present study examined the predictors of repeat mammography. It was hypothesized that higher social support is connected with mammography repeat.

METHODS

A cross-sectional study was carried out among 400 women 50 years and older in Sanandaj, Iran. Data was collected by the questionnaire including information on socio demographical variables and measuring social support level. Data was analyzed by SPSS16 software. Multiple logistic regression was used to determine the predictive power of demographic variables and dimensions of social support for repeat mammography.

RESULTS

Women aged 50-55 years had three times odds of repeat mammography compared to women aged 56-60 years) OR, 3.02). Married women had greater odds of repeat mammography compared to single women (P < 0.006). The probability of repeat mammography in women with higher social support was 0.93 times greater than the women with lower social support (OR, 0.93; 95 % CI, 0.91-0.95; P < 0.0001).

CONCLUSIONS

Iranian women are less likely repeat mammography than other Asian women. Identifying the associations between perceived social support and repeat mammography may offer detailed information to allow for future study and guide the development of interventions not only for Iranian women but also for similar cultural that received pay too little attention to date in the breast cancer literature.

Opportunities and challenges for the use of large-scale surveys in public health research: a comparison of the assessment of cancer screening behaviors

Large-scale surveys that assess cancer prevention and control behaviors are a readily available, rich resource for public health researchers. Although these data are used by a subset of researchers who are familiar with them, their potential is not fully realized by the research community for reasons including lack of awareness of the data and limited understanding of their content, methodology, and utility. Until now, no comprehensive resource existed to describe and facilitate use of these data. To address this gap and maximize use of these data, we catalogued the characteristics and content of four surveys that assessed cancer screening behaviors in 2005, the most recent year with concurrent periods of data collection: the National Health Interview Survey, Health Information National Trends Survey, Behavioral Risk Factor Surveillance System, and California Health Interview Survey. We documented each survey's characteristics, measures of cancer screening, and relevant correlates; examined how published studies (n = 78) have used the surveys' cancer screening data; and reviewed new cancer screening constructs measured in recent years. This information can guide researchers in deciding how to capitalize on the opportunities presented by these data resources.

What factors explain disparities in mammography rates among Asian-American immigrant women? A population-based study in California

BACKGROUND

The purpose of this study was to compare rates of screening mammography among immigrant women in five Asian-American ethnic groups in California, and ascertain the extent to which differences in mammography rates among these groups are attributable to differences in known correlates of cancer screening.

METHODS

Using 2009 data from the California Health Interview Survey, we compared the rates of mammography among Chinese, Filipino, Japanese, Korean, and Vietnamese immigrants 40 years and older. To assess the impact of Asian ethnicity on participation in screening, we performed multiple logistic regression analysis with models that progressively adjusted for acculturation, sociodemographic characteristics, access to health care, and breast cancer risk factors, and examined the predicted probabilities of screening after adjusting for these factors.

FINDINGS

Participation in screening mammography differed according to ethnicity, with Filipina and Vietnamese Americans having the highest rates and Korean Americans having the lowest rates of lifetime and recent (past 2 years) screening. These differences decreased substantially after adjusting for acculturation, sociodemographic factors, and risk factors of breast cancer, but differences remained, most notably for Korean Americans, who continued to have the lowest predicted probability of screening even after adjustment for these factors.

CONCLUSIONS

This analysis draws attention to low mammography screening rates among Asian-American immigrants, especially recent immigrants who lack health insurance. Given that their breast cancer incidence is rising with length of stay in the United States, it is important to increase regular mammography screening in these groups.

Effectiveness of interventions to increase screening for breast, cervical, and colorectal cancers: nine updated systematic reviews for the guide to community preventive services

CONTEXT

Screening reduces mortality from breast, cervical, and colorectal cancers. The Guide to Community Preventive Services previously conducted systematic reviews on the effectiveness of 11 interventions to increase screening for these cancers. This article presents results of updated systematic reviews for nine of these interventions.

EVIDENCE ACQUISITION

Five databases were searched for studies published during January 2004-October 2008. Studies had to (1) be a primary investigation of one or more intervention category; (2) be conducted in a country with a high-income economy; (3) provide information on at least one cancer screening outcome of interest; and (4) include screening use prior to intervention implementation or a concurrent group unexposed to the intervention category of interest. Forty-five studies were included in the reviews.

EVIDENCE SYNTHESIS

Recommendations were added for one-on-one education to increase screening with fecal occult blood testing (FOBT) and group education to increase mammography screening. Strength of evidence for client reminder interventions to increase FOBT screening was upgraded from sufficient to strong. Previous findings and recommendations for reducing out-of-pocket costs (breast cancer screening); provider assessment and feedback (breast, cervical, and FOBT screening); one-on-one education and client reminders (breast and cervical cancer screening); and reducing structural barriers (breast cancer and FOBT screening) were reaffirmed or unchanged. Evidence remains insufficient to determine effectiveness for the remaining screening tests and intervention categories.

CONCLUSIONS

Findings indicate new and reaffirmed interventions effective in promoting recommended cancer screening, including colorectal cancer screening. Findings can be used in community and healthcare settings to promote recommended care. Important research gaps also are described.

Different effects of multiple health status indicators on breast and colorectal cancer screening in a nationally representative US sample

OBJECTIVE

To examine the independent associations between multiple health status indicators and breast and colorectal cancer screening (CRCS) in a national US sample.

STUDY DESIGN AND SETTING

Analysis of cross-sectional data from the 2005 National Health Interview Survey (NHIS) involved 5115 men and 7100 women aged 50 years and older.

MEASURES

Health status indicators included: self-reported perceived health status, number of chronic conditions, and functional limitation due to a chronic condition. Individuals were considered adherent to CRCS guidelines if they reported having a home-based fecal occult blood test in the past year or endoscopy in the past 10 years. Women were adherent to breast cancer screening guidelines if they reported having a mammogram in the previous 2 years. Statistical analyses were conducted using SUDAAN software to account for the complex sampling of the NHIS survey. Logistic regression was used to examine associations between each of the health status indicators and screening adherence for CRCS and mammography and to calculate estimated screening rates.

RESULTS

The three health status indicators were independently and differentially associated with screening adherence. Poor perceived health was associated with lower mammography among women, whereas a greater number of chronic conditions were consistently associated with greater screening. In adjusted analyses, functional limitation was only significantly associated with greater CRCS among women.

CONCLUSIONS

Our analyses included three common indicators of health status and provide new evidence of their complex associations with cancer screening. Future studies must examine the mechanisms by which these indicators influence screening recommendations and adherence among older adults over time.
