[PMID: 37262079 DOI: 10.1371/journal.pone.0286518] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Accepted: 05/17/2023] [Indexed: 06/03/2023] Open
Abstract
BACKGROUND The burden of non-communicable diseases (NCDs) is increasing. Risk perception of NCDs is an important factor towards the uptake of preventive health interventions. There are various questionnaires assessing risk perception of NCDs, but no internationally standardized questionnaire has been available. Identification of factors associated with risk perception of NCDs may facilitate the development of targeted interventions. This systematic review aims to identify available questionnaire assessing risk perception of NCDs and the factors associated with risk perception of NCDs. METHODS The reporting of this systematic review is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We carried out a literature search through three databases (Scopus, PubMed, Web of Science) and targeted original article published in English between 2012 and 2021. Quality appraisal of the eligible articles was conducted using the Mixed Methods Appraisal Tool. Findings were synthesized using content analysis. RESULTS A total of 86 studies were included. We found a variety of questionnaires assessing risk perception of NCDs, with many differences in their development, domains, items and validity. We also identified several personal, sociopsychological and structural factors associated with risk perception of NCDs. LIMITATIONS Most of the included studies were of cross-sectional design, and therefore the quality of evidence was considered low and exhibit a high risk of bias. The role of publication bias within this systematic review should be acknowledged as we did not include grey literature. Additionally, language bias must be considered as we only included English-language publications. CONCLUSION Further development and testing of available questionnaire is warranted to ensure their robustness and validity in measuring risk perception of NCDs. All the identified factors deserve further exploration in longitudinal and experimental studies.

Perceived risk and risk reduction behaviours of female first-degree relatives of breast cancer patients attending care at Uganda cancer institute. Psychooncology 2023; 32:34-41. [PMID: 35584282 DOI: 10.1002/pon.5963] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2022] [Revised: 05/04/2022] [Accepted: 05/08/2022] [Indexed: 02/04/2023]
Abstract
OBJECTIVE The objective of this study was to assess the perceived risk of breast cancer (BC) and adoption of risk reduction behaviours among female first-degree relatives (FDRs) of BC patients attending care at the Uganda Cancer Institute (UCI). METHODS A cross-sectional study was performed using a questionnaire to collect data between March to October 2019. Adult female FDRs of patients attending care at UCI were recruited consecutively. Breast cancer perceived risk was assessed using a verbal measure; 'My chances of getting BC are great' on a Likert scale with 5 response alternatives. Chi square tests and modified Poisson regression using generalised estimating equations model were used to determine associations and examine factors associated with perceived risk of BC. RESULTS We enrolled 296 FDRs from 186 female BC patients. Few participants 118/296 (40%) had high perceived risk of BC. Majority 165/296 (56%), had ever practiced breast self-examination. At the multivariable modified Poisson GEE model, women aged 36-45 years were more likely to perceive themselves to be at high risk of developing BC compared to women aged 18-25 years (adjusted prevalence ratio: 1.174; 95% confidence interval [95%CI] = 1.05-2.88; p value = 0.030) after adjusting for age, religion, educational level and residence. CONCLUSION Few FDRs of BC patients perceived themselves to be at high risk of developing BC and do not seek risk reduction measures including screening and early diagnosis approaches. Breast cancer health education especially targeting younger women should emphasize the increased risk of BC in FDRs.

Abstract
Aim: While screening mammography has been interrupted in many countries during the coronavirus disease (COVID-19) pandemic lockdowns, less is known about missed mammography screening and its reasons in the later periods of pandemic. In this study it was aimed to find out the rate and the reasons for missed mammography screening, and the associated factors in Turkey during the COVID-19 pandemic.
Material and Method: In this single center, cross-sectional observational study women who underwent mammography screening between September 1st to October 1st 2021 (15 months after the start of the COVID-19 pandemic) were recruited. A questionnaire developed for the purpose of this study was used to assess the participant characteristics, whether a screening mammography has been missed during pandemic and its reasons.
Results: The sample comprised of 144 women with a mean age of 50.2±8.0. Most of the sample were married and had children, 34.0% had chronic diseases. Ninety women (62.5%) misssed a screening mammography in the pandemic. Having equal or less than primary school education was associated with higher delay in mammography screening when compared to being having higher education (OR=2.26, 95%CI= 1.09- 4.69, p=0.027). Fear of COVID-19 transmission (92.2%) was the most common reason for missed mammography screening.
Conclusion: This study firstly demonstrated that most of the women delayed their screening mammography after the lockdown periods in the COVID-19 pandemic in Turkey and having equal or less than primary school education was associated with higher missed screening rates than having higher education levels. Effective solutions are needed to address the reasons for missed mammography screening to reduce breast cancer related morbidity and mortality both for this pandemic and for regular times.

Perceived Breast Cancer Risk among Female Undergraduate Students in Ghana: A Cross-Sectional Study. JOURNAL OF ONCOLOGY 2021; 2021:8811353. [PMID: 33953748 PMCID: PMC8064772 DOI: 10.1155/2021/8811353] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 03/21/2021] [Accepted: 04/08/2021] [Indexed: 12/24/2022]
Abstract
Background While breast cancer accounts for the highest mortality among women across the globe, little is known about its perceived risks among them. We examined the perceived risk of breast cancer among undergraduate female university students in Ghana. Methods This was a cross-sectional survey of 358 undergraduate female students at the University of Health and Allied Sciences, Ghana. Descriptive and inferential statistics comprising frequencies, percentages, chi-square, and binary logistic regression analyses were used in analysing the data collected. All analyses were done using STATA Version 13.1. Results Seventy-three percent were aware of breast cancer and 45.2% out of this did not perceive themselves to be at risk of breast cancer. Academic year (p=0.02), school (p=0.01), knowledge of someone with breast cancer (p < 0.001), family history of breast cancer (p < 0.001), current use of oral pills/injectable contraception (p=0.03), history of breast cancer screening (p < 0.001), and intention to perform breast self-examination (p < 0.001) were the risk factors of breast cancer risk perception. Students without a family history of breast cancer were 90% less likely to perceive breast cancer risk (AOR = 0.10, 95% CI = 0.04-0.29) compared with those having a family history of breast cancer. Students who had never screened for breast cancer were also 62% less likely to perceive that they were at risk of breast cancer (AOR = 0.10, 95% CI = 0.04-0.29) compared with those who had ever screened for breast cancer. Conclusion This study showed that female university students tend to estimate their breast cancer risk based on their experience of breast cancer. Students who have ever screened for breast cancer and those with the intention to perform breast self-examination in the future are more likely to perceive themselves as being at risk and thus take action to avoid getting breast cancer.

Abstract
BACKGROUND The accuracy of subjective risk perception is a matter of concern in breast cancer development. The objective of this study was to evaluate the accuracy of self-perceived risk assessment of breast cancer development and compared to actual risk in Iranian women. METHODS The demographic, clinical, and reproductive characteristics of 800 women aged 35-85 years were collected with an in-person interview. The self-perceived risk and the actual risk were assessed using the visual analog scale (VAS) and he Gail model respectively. Gail's cutoff of 1.66% risk was used to categorize the estimated 5-year actual risk as low/average risk (< 1.66%) and high risk (≥ 1.66). In low/average risk, if the self-perceived risk > actual risk, then individuals were considered as overestimating. Similarly, in high-risk women, if the perceived risk < actual risk, then, the subjects were labeled as under-estimate; otherwise, it was labeled as accurate. The Kappa statistics were used to determine the agreement between self-perceived risk and actual risk. ROC analysis was applied to determine the accuracy of self-perceived risk in the prediction of actual risk. RESULTS The perceived risk was significantly higher than actual risk (p = 0.001, 0.01 for 5-year and lifetime risk respectively). Both in low and high-risk groups about half of the women over-estimate and underestimate the risk by subjective risk perception. For a 5-year risk assessment, there was no agreement between perceived risk and actual risk (Kappa = 0.00, p = 0.98) but a very low agreement between them in lifetime risk assessment (Kappa = 0.09, p = 0.005). The performance of accuracy of risk perception versus actual risk was very low (AUC = 0.53, 95% CI 0.44-0.61 and AUC = 0.58, 95% CI 0.54-0.62 for the 5-year risk and lifetime risk respectively). CONCLUSION The clinical performance of risk perception based on VAS is very poor. Thus, the efforts of the public health education program should focus on the correct perception of breast cancer risk among Iranian women.

Abstract
The increase of breast cancer (BC) incidence has drawn attention to BC risk as means of reducing mortality and morbidity of the disease. The aim of this study was to determine the accuracy of BC risk perception, evaluate factors that affect risk perception and assess the correlation between BC risk perception and attitudes towards BC chemoprevention. A cross-sectional study included total of 258 women with average and high-risk for BC according to the Breast Cancer Risk Assessment Tool (BCRAT). All data were collected by face-to-face interview by three trained 6th year medical school students using a 54-item questionnaire. Each participant's actual BC risk was compared to a perceived risk and the accuracy of the BC risk self-assessment was determined. 72% of high-risk women underestimated their BC risk (p < 0.001). One third of subjects with a family history of BC have also underestimated their own risk (p = 0.002). Women who responded to screening mammography were more informed about BC risk factors (p = 0.001). General knowledge about BC chemoprevention was surprisingly low, regardless of the accuracy of BC risk self-assessment. High-risk women appear to be unrealistically optimistic, since there was a significant difference between the accuracy of self-perceived risk and the objective BC risk.

Abstract
Background: Previous studies suggest that education and income affect Brazilian women's breast cancer prevention behavior. The present study focused on the impact of perceived and estimated risk on mammography screening (MS) behavior. Materials and Methods: Information regarding socioeconomic variables and risk perception was obtained from 396 healthy women aged 40-79 years. Perceived comparative risk was measured on a seven-point Likert scale. A Breast Cancer Risk Assessment Tool of 5-year risk to develop breast cancer was used to determine objective risk. Estimated comparative risk was determined as categories of perceived risk relative to the objective risk. Regression analysis was applied to determine odds ratios (ORs) and confidence intervals (95% CIs) of variables. Results: Asked about the potential of MS to lower risk of death because of breast cancer, 215 (54.29%) responded that it does not lower risk. Women with low perceived comparative risk had a twofold (OR = 0.493; 95% CI: 0.24-1.00) decreased chance to participate in MS annually, compared with women with high-perceived comparative risk (p = 0.020). Women without family history had a 7.6-fold (OR = 0.132; 95% CI: 0.07-0.25) decreased chance of having a high-perceived comparative risk (p = 0.000). If compared with underestimation, the overestimation and accurate estimation of comparative risk tended to be associated with a decreased chance of MS attendance (p = 0.017). Regression modeling indicated that low educational level, no occupation, and no family history decreased the chance of women having MS (p = 0.040; p = 0.010; p = 0.022). Conclusions: Risk perception depended on family history. Present data did not indicate that overestimation, or accurate estimation of comparative risk, increased chance of MS attendance. Educational level, occupation status, and family history, instead, determined MS performance.

Socio-culturally mediated factors and lower level of education are the main influencers of functional cervical cancer literacy among women in Mayuge, Eastern Uganda. Ecancermedicalscience 2020; 14:1004.

Abstract
Background Health literacy (HL) is the degree of an individual’s knowledge and capacity to seek, understand and use health information to make decisions on one’s health, yet information on the functional level of cervical cancer literacy in Mayuge and Uganda as a whole is lacking. We, therefore, assessed the level of functional cervical cancer literacy among women aged 18–65 years in Mayuge district in five functional HL domains; prior knowledge, oral, print, numeracy and e-health. Understanding the factors associated with cervical cancer literacy is also pertinent to cervical health communication programming, however, no study has documented this in Uganda and particularly in Mayuge. Mayuge is a rural population based cancer registry and one of the sites for piloting cancer control interventions in Uganda. We also assessed the factors associated with cervical cancer literacy and awareness about currently available cervical cancer preventive services. Methods The study protocol was approved by the Uganda Cancer Institute research and ethic committee (UCI-REC). In August 2017, we assessed five HL domains; cervical cancer knowledge, print literacy, oral literacy using audio-clip, numeral literacy and perceived e-HL among 400 women at household levels. Correct response was scored 1 and incorrect response was scored 0 to generate the mean percentage score for each domain. The mean scores were classified as limited, basic and proficient bands based on the McCormack HL cut-offs scale for knowledge, print, oral and e-health and Weiss cut-offs in the newest vital signs (NVS) for numeracy. We used the cervical cancer literacy scores to explore the effect of selected study variables on cervical cancer literacy. We also conducted five focus group discussions (FGDs) based on the theoretical constructs of the PEN-3 model. Results The majority (96.8%) of the participants demonstrated a limited level of cervical cancer literacy with a mean score of 42%. Women who had completed a primary level of education or lower (OR = 3.91; p = 0.044) were more likely to have limited cervical cancer literacy. The qualitative data indicated that the women had limited cervical cancer literacy coupled with limited decisional, social and financial support from their male partners with overall low locus of control. Most (92.3%) of the women were not aware of the available cervical cancer services and had no intention to screen (52.5%). Conclusions The women in Mayuge in general have limited cervical cancer literacy except oral HL domain. Limited cervical cancer literacy was highest among women with lower level of education and overall literacy seemed to be influenced on the higher side by socio-cultural constructs characterised by limited decisional, social and personal resources among the women with overall low locus of control. The Mayuge women further demonstrated scant knowledge about the available health services in their district and low intention to screen. Multi-strategy cervical health empowerment programme is needed to improve cervical HL using orally disseminated messages.

Abstract
ABSTRACT Objective: To analyze the association of the perception of the elderly on the risk factors for falls. Methods: An Analytical cross-sectional study with 190 elderly from the Healthy Longevity Program of a public university in Mato Grosso, from May to August 2016. The collection wasdone through a structured interview and vignettes. Performed descriptive and bivariate analyzes - Pearson chi-square test (x2) significance level of 5%. The crude and adjusted prevalence ratios (PR), with confidence intervals (95%), were also estimated, followed by Poisson multiple regression. Results: Of the participants, 64.2% had a satisfactory perception about the risk factors for falls. The prevalence of unsatisfactory risk perception was 105% higher in those with income from 1 to 3 minimum wages, 75% higher in those with low risk of falls and 46% higher in those who did not attend another social group. Conclusion and implications for the practice: A significant proportion of the elderly have an unsatisfactory risk perception for the risk factors for falls associated with low income, not attending another social group and the low risk of falls. Knowledge about the risk perception of falls in the elderly helps nurses to plan and implement fall prevention programs for this population.

Abstract
Breast cancer (BC) is the most prevalent cause of cancer-related death in women worldwide. BC is frequently associated with elevated levels of nicotinamide phosphoribosyltransferase (NAMPT) in blood and tumor tissue. MicroRNA-494 (miR-494) has been described to play key anti-tumor roles in human cancers. The aim of the present study was to investigate the inhibitory effect of miR-494 on NAMPT-mediated viability of BC cells. In this experimental study, MCF-7 and MDA-MB-231 cells were cultured and then transfected with miR-494 mimic, miR-494 inhibitor and their negative controls. The mRNA and protein expression of NAMPT were assessed using real-time PCR and Western blotting, respectively. Subsequently, intracellular NAD levels were determined by a colorimetric method. Finally, cell apoptosis was examined by flow cytometry. Bioinformatics evaluations predicted NAMPT as a miR-494 target gene which was confirmed by luciferase reporter assay. Our results showed an inverse relationship between the expression of miR-494 and NAMPT in both MCF-7 and MDA-MB-231 cell lines. miR-494 significantly down-regulated NAMPT mRNA and protein expression and was also able to reduce the cellular NAD content. Cell viability was decreased following miR-494 up-regulation. In addition, apoptosis was induced in MCF-7 and MDA-MB-231 cells by miR-494 mimic. Our findings indicate that miR-494 acts as a tumor suppressor and has an important effect in suppressing the growth of BC cells through NAMPT. Therefore, miR-494 might be considered as a novel therapeutic target for the management of human breast cancer.

Abstract
The aims of this study are to assess knowledge of inheritance characteristics of breast cancer and risk reduction strategies and to determine risk perception and the factors affecting risk perception of women with family history. There is a gap in our understanding of risk perception and knowledge of genetic aspect of breast cancer and risk reduction strategies in women with a family history of breast cancer. The study design is descriptive cross-sectional study. Between January 2015 and 2016 at a training and research hospital in Turkey, 117 women who were the first- and second-degree relatives of breast cancer patients were included in the study. Perceived risk scale, cancer worry chart, and a knowledge assessment form were used to collect data. Of the women, 34.1% were first-degree relatives of a breast cancer patient, and knowledge score was 6.9 ± 2.19 out of 11. Almost half of the women (41.9%) moderately worry about the chances of getting breast cancer, and half of the women (51.3%) ranked their perceived risk as moderate (26-50% out of 100%). There is a significant difference between the perceived risk and educational level, having genetic testing, and a significant relationship between the perceived risk and worry level of women. However, breast cancer screening behavior was not affected by risk perception. The knowledge of women regarding inheritance characteristics of breast cancer and risk reduction strategies was moderate, but still majority of women have moderate or higher level of risk perception and are worried about getting breast cancer. Therefore, interventions should be planned to reduce worry and to increase risk reduction strategies such as screening and other health behaviors in women at risk for breast-ovarian cancer.

Abstract
BACKGROUND The increase in breast cancer incidence has enhanced attention towards breast cancer risk. The aim of this study was to determine the risk of breast cancer and risk perception of women, factors that affect risk perception, and to determine differences between absolute risk and the perception of risk. METHODS This cross-sectional study was carried out among 346 women whose score in the Gail Risk Model (GRM) was ≥ 1.67% and/or had a 1st degree relative with breast cancer in Bahçeşehir town in Istanbul, Turkey between Jul 2012 and Dec 2012. Data were collected through face-to-face interviews. The level of risk for breast cancer has been calculated using GRM and the Breast Cancer Risk Assessment Form (BCRAF). Breast cancer risk perception (BCRP), has been evaluated by visual analogue 100-cm-long scale. RESULTS Even though 39.6% of the women considered themselves as high-risk carriers, according to the GRM and the BCRAF, only 11.6% and 9.8% of women were in the "high risk" category, respectively. There was a positive significant correlation between the GRM and the BCRAF scores (P<0.001), and the BCRAF and BCRP scores (P<0.001). Factors related to high-risk perception were age (40-59 yr), post-menopausal phase, high-very high economic income level, existence of breast cancer in the family, having regular breast self-examination and clinical breast examination (P<0.05). CONCLUSION In women with high risk of breast, cancer there is a significant difference between the women's risk perception and their absolute risk level.
