Breast Cancer Knowledge and Mammography Use Among Asian American Women Aged 40 and Older: Using the Transtheoretical Model Approach.

Mammography screening rates remain low among Asian American women (AAW). The aims of our study were to: (a) assess breast cancer knowledge and mammography screening behaviors, and (b) identify the factors related to the transtheoretical model (TTM) stages of change in relation to mammography utilization among AAW aged 40 and older. Using a cross-sectional design, a convenience sample of 714 AAW completed a structured questionnaire in 2021. Participants demonstrated a moderate level of knowledge regarding breast cancer and mammography. Only 34.2% of the participants reported obtaining regular mammograms. The ordinal logistic regression indicated that age, birthplace, health perception, breast biopsy history, breast cancer knowledge, self-efficacy, and perceived barriers were correlated with TTM stages of change. Our results highlight the need for implementing effective interventions aimed at increasing knowledge and screening rates for breast cancer among AAW. Additional TTM studies with AAW are needed to determine the relationships among TTM constructs and develop theory-based programs to improve adherence to screening guidelines. Future research using a mixed-method design may provide opportunities to explore complex phenomena associated with breast cancer screening behaviors. Finally, further assessments of the Breast Cancer Knowledge Scale's psychometric properties are necessary to improve this instrument.

Human papillomavirus vaccination: a quantitative cross-sectional study of perceived barriers, influential advisors, and acculturation among Chinese college students aged 18-26 in the USA.

HPV vaccines are highly effective in preventing HPV-associated cancers; however, HPV vaccination uptake is low among Chinese students studying at U.S. colleges. The purposes of this study were to evaluate (a) perceived barriers and influential others trusted for advice regarding HPV vaccination and (b) factors (i.e. HPV vaccination, acculturation) related to barriers and influential advisors among 18- to 26-year-old Chinese students attending U.S. colleges. We used a cross-sectional design to obtain self-reported data in 2019 from a chain-referral sample of 213 Chinese students. Among 125 respondents who were unvaccinated or partially vaccinated, the reported barriers to receiving the HPV vaccine included: (a) lack of recommendations from a healthcare provider, (b) lack of risk perception for HPV infection, and (c) limited knowledge about HPV vaccination locations. The influential advisors for receiving HPV vaccination were doctors, parents, self, nurses, and same-sex friends. Multivariate analysis revealed that unvaccinated respondents were more likely to report the following barriers to HPV vaccination: (a) lack of recommendations from a healthcare provider, (b) lack of risk perception for HPV infection, (c) limited knowledge about vaccination locations, and (d) uncertainty about effectiveness. High Asian identified respondents were more likely to perceive barriers related to limited knowledge about vaccination locations and uncertainty about effectiveness, while they were less likely to state nurses as influential advisors. Individuals who received one or more HPV vaccine doses were more inclined to view same-sex friends and nurses as influential advisors for HPV vaccination. The influence of culture on preferences for information sources, such as specific providers and provider gender, needs to be addressed. Programs designed to decrease barriers and improve HPV vaccination among Chinese students should also focus on acculturation status.

Exploring Sources of Information and Religious Beliefs in Regard to HPV and Vaccination Among Hispanic/Latino College Students in the USA.

We identified (a) sources of and communication about HPV information and (b) factors (e.g., religious affiliations) related to information sources and communication regarding HPV among Hispanic/Latino college students attending US institutions. Applying a cross-sectional design, we recruited 209 participants from US colleges. Most participants used healthcare professionals for their sources and communication about HPV-related information. Respondents who were practicing Catholics tended to use the Internet and healthcare professionals as their sources for HPV-related information. Healthcare professionals, TV, schoolteachers, same-sex friends, and family members affected participants' HPV vaccination, knowledge, and attitudes. Religious faith may influence information-seeking behaviors and requires more research.

The role of state breastfeeding laws and programs on exclusive breastfeeding practice among mothers in the special supplemental nutrition program for Women, Infants, and Children (WIC).

BACKGROUND: It is unclear if state laws supporting breastfeeding are associated with exclusive breastfeeding (EBF) practice among low-income mothers participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). The main objectives of our study were to assess the relationship between such laws and EBF among WIC-participating mothers and to assess whether this association varied by employment status. We also assessed how mother's exposure to WIC breastfeeding consultation was associated with EBF. METHODS: A cross-sectional study was conducted across seven WIC program locations (i.e., Georgia, Massachusetts, Nevada, Pennsylvania, Wisconsin, Wyoming, Chickasaw Nation) between July-August 2020. Data were collected using convenient sampling from each program location and surveys were administered electronically or on paper to WIC-participating mothers. We restricted our analysis to data from 1161 WIC-participating mothers with infants aged zero to five months old. Multivariable mixed models were used to estimate the relationship between our exposures of interest (i.e., number of laws supporting breastfeeding, employment-related breastfeeding laws, WIC breastfeeding consultation) and EBF, while controlling for potential confounders and accounting for clustering by program location. Effect modification by employment status was assessed on the additive and multiplicative scales. RESULTS: Among WIC-participating mothers living in program locations with no employment-related breastfeeding laws, EBF was 26% less prevalent for employed mothers compared to unemployed mothers (adjusted prevalence ratios [aPR]: 0.74, 95% CI: 0.67,0.83). Among all mothers, a one-unit increase in laws supporting breastfeeding was not associated with EBF (aPR: 0.88, 95% CI: 0.71,1.10). However, among employed mothers, living in areas with more employment-related laws was associated with a higher prevalence of EBF (aPR: 1.43, 95% CI: 0.83, 2.44). Infants whose mothers received a WIC breastfeeding consultation had 33% higher prevalence of being exclusively breastfed compared to infants whose mothers did not receive a WIC breastfeeding consultation (aPR: 1.33, 95% CI: 1.05,1.70). CONCLUSIONS: Infants whose WIC-participating mothers were employed, were less likely to be exclusively breastfed, but our effect modification analyses showed that laws supporting breastfeeding at the workplace may promote EBF among employed women. EBF was more prevalent among mothers who received a WIC breastfeeding consultation compared to those who did not receive such a consultation.

Sources of Information and Communication About HPV Among Chinese Students Attending U.S. Colleges: Implications for Culturally Appropriate Strategies.

INTRODUCTION: Little is known about human papillomavirus (HPV) information sources and communication among Chinese students attending U.S. colleges. We assessed information sources and communication about HPV and HPV vaccines among this population. METHODOLOGY: A cross-sectional design with 449 participants was conducted by using a questionnaire and snowball sampling. Summary statistics and multiple logistic regression were used. RESULTS: The most common sources of HPV information included the internet and friends. Communication about HPV occurred most frequently among friends, family, and health professionals. Those who had better HPV knowledge and attitudes and were vaccinated against HPV were more likely to use internet, friends, family, and health professionals as their information sources. DISCUSSION: Because the internet, friends, and families are likely sources for HPV information and communication, future internet-based culturally appropriate education should offer information not only to Chinese students but also to their social circles. Cultural beliefs may affect HPV prevention and should be examined.

HPV vaccination, information sources, and acculturation among Chinese college students aged 18-26 in the United States.

Human papillomavirus (HPV) vaccination behaviors among Chinese college students (CCS) in the United States are affected by social determinants of health. Using a self-report questionnaire and a snowball sampling technique, this cross-sectional study investigated (a) HPV vaccination practices; (b) primary social networking platforms and preferred means of receiving HPV information; and (c) the influence of acculturation on HPV vaccination, HPV information sources, and social networking use among 213 CCS aged 18-26 in the United States. About half (50.7%) had received one to three doses of an HPV vaccine, and 91.7% had received their first dose. The most popular social networking platforms were WeChat (69.5%), Instagram (58.7%), text messaging (55.4%), and Facebook (47.4%). Preferred means of receiving future HPV information included the internet, online social networking, and health professionals. Participants with high Asian identification (AI) were less likely to receive the HPV vaccine than those with high Western identification. Participants with high AI were more likely to use WeChat for their social networking but less likely to use US-based social media platforms. Acculturation, preferred social networking platforms, and sources and communication of HPV (i.e., health professionals, family members, schoolteachers, friends) influenced participants' HPV vaccination. To promote equity of access to health messages and increase HPV vaccination, future efforts should pay attention to CCS with high AI and incorporate their cultural beliefs and practices. Given that nonprofessionals (e.g., family, friends) were influential factors in HPV vaccination, it is critical to tailor interventions for CCS to the recipients and their social circles.

The interrelationship between water access, exclusive breastfeeding and diarrhea in children: a cross-sectional assessment across 19 African countries.

BACKGROUND: Access to an improved water supply and practicing exclusive breastfeeding are essential for improving maternal and child health outcomes. However, few studies have been equipped to assess the interdependencies between access to improved water, practicing exclusive breastfeeding, and child health. The primary aim of our study was to assess whether access to an improved water supply and water-fetching were associated with mothers' practice of exclusive breastfeeding. METHODS: We analyzed data on 247 090 mothers with children 5 months old or less using Multiple Indicator Cluster Surveys from 19 African countries. Multivariable logistic regression was used to estimate the relationship between our exposures and exclusive breastfeeding practice, while meta-analytic methods were used to pool adjusted estimates across 19 countries. RESULTS: The prevalence of exclusive breastfeeding ranged from 22% in Nigeria to 70% in Malawi. Pooled results showed water-fetching was not associated with exclusive breastfeeding (adjusted prevalence odds ratios (aPOR) = 1.04, 95% confidence interval (CI) = 0.89, 1.21). Access to an improved water source was also not associated with exclusive breastfeeding (aPOR = 1.06, 95% CI = 0.94, 1.21). Across all countries many women were spending a significant amount of time water-fetching each day (mean time varied from 20 minutes in Ghana to 115 minutes in Mauritania). Exclusively breastfed children had 33% lower odds of diarrhea than those who were not exclusively breastfed (aPOR = 0.67, 95% CI = 0.56, 0.78). CONCLUSION: Our study is the first to assess the relationship between access to improved water supply, water-fetching and exclusive breastfeeding. We found that access to water supply and time spent by mothers fetching water were not associated with exclusive breastfeeding practice, even though mothers spent significant time fetching water.

Reasons and influential recommendations associated with HPV vaccination among Chinese college students in the USA.

OBJECTIVES: To evaluate (a) reasons for not receiving recommended doses of the human papillomavirus (HPV) vaccine, (b) the most influential recommending source in getting the HPV vaccine, and (c) associated factors among Chinese college students in the United States. METHODS: A cross-sectional design utilizing a structured self-report questionnaire was used. PARTICIPANTS: A network sample of 449 participants aged 18 or older completed the survey between March and May of 2018. RESULTS: Only 172 participants (38.3%) had received the HPV vaccine. The most common reason was that participants had never received recommendations from healthcare providers regarding HPV vaccines. Recommendations from doctors were the most cited source in deciding HPV vaccine uptake. Factors associated with reasons and recommendation sources included attitudes toward HPV, gender, school year, age, major, and health insurance. CONCLUSIONS: Healthcare providers play an important role in promoting HPV vaccination among Chinese college students. More research is needed for this understudied population.

Knowledge, attitudes, and practices related to human papillomavirus vaccination among college students in a state university: Implications for nurse practitioners.

BACKGROUND: Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States and disproportionately affects adolescents and young adults. Although a safe and efficacious vaccine is available, many college students are unimmunized against HPV. Most students presenting to college health centers are within the age range for catch-up immunization, giving nurse practitioners (NPs) in this setting an opportunity to increase vaccination rates. More information is needed about college students' HPV knowledge, attitudes, and vaccination uptake so that NPs can make effective vaccine recommendations to this population. PURPOSE: To examine (a) Knowledge and attitudes about HPV and its vaccine; (b) HPV immunization practices; and (c) factors associated with HPV knowledge, attitudes, and vaccination among college students in a US university. METHODS: This cross-sectional quantitative study collected data from participants in a state university student health center. Data collected included knowledge, attitudes, and practices about HPV and its vaccine from 627 students. RESULTS: Participants had a moderately low HPV knowledge but positive attitudes toward HPV and its vaccine. Participants with a higher level of HPV knowledge were US born, health-related majors, married or divorced, and had positive attitudes. Higher HPV knowledge, vaccine uptake, and a family history of cervical cancer were associated with positive attitudes. Predictors for vaccine uptake include being a health-related major and positive vaccine attitudes. IMPLICATIONS FOR PRACTICE: The results of this study help NPs, registered nurses, and other health care providers make effective HPV vaccine recommendations to college students. Students with positive HPV attitudes can serve as peer educators to increase HPV vaccination awareness in this population.

Human papillomavirus knowledge, attitudes, and vaccination among Chinese college students in the United States.

Human papilloma virus (HPV) is the most common sexually transmitted infection in the USA with some strains increasing the risk of certain cancers. The HPV vaccine, introduced in 2006, has reduced the infection rate, although racial/ethnic disparities in vaccination exist. Asian college students are among those with the lowest vaccination rates, however there has been little exploration as to why. The purposes of this study were to assess (a) knowledge and attitudes regarding HPV and its vaccine, (b) HPV vaccination practices, and (c) factors associated with HPV-related knowledge and attitudes, and vaccination among Chinese college students in the USA. This cross-sectional quantitative survey collected data face-to-face and online from 449 participants. The mean scores for HPV knowledge and attitudes were 40.87 and 2.36 indicating a low-to-moderate level of knowledge but a moderately positive attitude regrading HPV transmission and vaccination. Only half (50.8%) knew that the vaccination could be received after the age of 18 years. Only 38.3% reported having receiving at least one dose of the vaccine, with 92.4% receiving their first HPV vaccines in the USA. Multiple logistic regression showed that men and non-health sciences majors had lower knowledge about HPV. Older students, those without a primary care provider, and those who completed the survey in English had more negative attitudes about the HPV and vaccine. Participants who were younger, female, had a higher level of knowledge, had more positive attitudes, and completed the survey online were associated with better vaccination status. Findings from this study provide insight into Chinese college students' knowledge and attitudes about HPV and HPV vaccination and may be used to develop culturally sensitive programs that address the risk of HPV and the benefits of HPV vaccine.

Demographics, self-efficacy, benefits/barriers, stages of adopting pap testing among Korean American women.

Korean American women (KAW) experience the third highest incidence rate of cervical cancer among nine major Asian Americans. This study examined cervical cancer screening among KAW using constructs from the transtheoretical model (TTM). Using a cross-sectional survey design, 102 KAW aged 21-65 years of age were recruited through convenience sampling. Twenty-seven per cent of participants reported of never receiving a Pap smear. Women who were older and married were more likely to report being in the action/maintenance stages; women who perceived themselves to be in poor health were less likely to be in the action/maintenance stages. Higher self-efficacy and lower perception of barriers were significantly associated with more advanced TTM stages. The perceived benefits were not statistically different across TTM stages of change. A special attention should be given to young and unmarried KAW to increase screening participation. Impact statement What is already known on this subject? The utilisation of Pap test among Korean American women (KAW) was low. Using the transtheoretical model (TTM) approach has the potential to increase a screening adherence. What do the results of this study add? This is the first study to examine the association between TTM constructs related to Pap testing among KAW. Younger and unmarried women reported the lowest levels of screening attitudes or behaviours; and tailored efforts may be beneficial in increasing the screening among these women. What are the implications of these findings for clinical practice and/or further research? Increasing the self-efficacy and decreasing the barriers to obtaining Pap screening are critical to move Korean women to the advanced TTM stages. Further investigation is needed with KAW to fully understand the relationships between TTM constructs.

Scope-of-practice laws and expanded health services: the case of underserved women and advanced cervical cancer diagnoses.

BACKGROUND: Underserved women (rural, minority or poor) are disproportionally diagnosed with late-stage cervical cancer, indicative of inadequate access to, and use of, preventative healthcare. The Institute of Medicine (IOM) has proposed that nurse practitioners (NP) can address provider shortages among underserved populations, but to reduce shortages, scope-of-practice laws that restrict the delivery of care, must be revised. We examined the IOM recommendation of NP expanded scope-of-practice laws on reducing the disparity of underserved women diagnosed with late-stage cervical cancer. METHODS: We examined the cohort of 10 673 women diagnosed with cervical cancer between 2010 and 2014 and reported to the Surveillance, Epidemiology and End Results cancer registry. We linked state-level laws regarding NP scope-of-practice to patients with cancer by their state of residence, diagnosis date and law enactment date. Hierarchical regression was used to explore NP full scope-of-practice law's impact on late-stage cancer diagnoses considering the moderating effect of women living in medically underserved areas. We adjusted for known confounders available in this population-based data set. RESULTS: Medically underserved women living in states with laws that restrict NP full scope-of-practice are twofold more likely to be diagnosed with late-stage cancer; adjusted OR and 95% CI (OR 2.08, 95% CI 1.4 to 3.1). These disparities were not observed among underserved women living in areas with NP full scope-of-practice laws (OR 0.95, 95% CI 0.7 to 1.3). CONCLUSIONS: NP full scope-of-practice laws could provide a pragmatic and cost-effective solution to healthcare provider shortages associated with late stage of cervical cancer diagnoses among underserved women.

The influence of tourism-based provisioning on fish behavior and benthic composition.

Distribution of non-natural food (provisioning) to attract fish, though popular in coral reef tourism, has often been discouraged due to its assumed adverse effects on fish health and behavior. However, the effects of provisioning on community structure, anti-predator, and foraging behavior of teleost fishes, as well as their potential to indirectly affect benthic organisms, are not yet clear. Here, we compared fish composition, wariness, foraging behavior of herbivorous fishes, and the benthic cover between provisioned and control sites. We found significant differences in fish abundance, species number, and composition at some locations, but not all. Although most provisioned herbivorous fish did not reduce their biting rates of benthic algae, provisioned sites still had higher coverage of green macroalgae. Our results dispute widely held presumptions on the effects of tourism-based provisioning on the ecology and behavior of teleost fishes, as well as the benthic cover. These findings suggest that while regulation of provisioning is necessary to manage and mitigate any deleterious outcomes, when moderated and monitored, it could still provide an educationally beneficial tool for coral reef ecotourism.

Assessing perceived benefits/barriers and self-efficacy for cervical cancer screening among Korean American women.

A large proportion of Korean American women (KAW) do not receive regular cervical cancer screening. Self-report data from 102 KAW were analyzed by multiple linear regressions. As compared to women in action/maintenance, women in precontemplation/relapse stages were less likely to agree that a Pap test is important for health and were more likely to endorse barriers to testing (cost, not having a female doctor, preference for Korean medicine). Women in precontemplation/relapse stages also reported lower scores on self-efficacy items (travel large distances, pain perceptions, financial costs, and time). Differences in specific aspects may be informative for interventions to improve screening rates among KAW.

Perceived Benefits and Barriers of Cervical Cancer Screening Among Chinese American Women.

PURPOSE/OBJECTIVES: To explore the perceived benefits and barriers to cervical cancer screening among Chinese American women using stages of the Transtheoretical Model of Change.
. DESIGN: Cross-sectional design with self-report surveys. 
. SETTING: Chinese communities (e.g., churches, supermarkets, restaurants) in Northern California and Northern Nevada. 
. SAMPLE: 121 Chinese women aged 21-65 years living in Northern California and Northern Nevada. 
. METHODS: A snowball sampling technique using personal contacts was used.
. MAIN RESEARCH VARIABLES: Stages of change and perceived benefits and barriers to cervical cancer screening. 
. FINDINGS: Participants in the action/maintenance stage were most likely to believe that cervical cancer was treatable if caught early. Women in the contemplation/preparation stage were more likely to state that they worried about or feared screening, that it was too expensive, and that they would want to use Chinese medicine to cure an illness before trying Western medicine. Women in the precontemplation/relapse stage were most likely to report that they did not know where to get screened and that their partner would not want them to be screened.
. CONCLUSIONS: Perceived benefits and barriers to screening were differentially associated with the stages of change. Results may support culturally sensitive and theory-based programs to improve screening rates among Chinese American women. 
. IMPLICATIONS FOR NURSING: The results suggest the importance of cultural sensitivity among nursing providers when working with Chinese Americans to provide more relevant, holistic care.

Latina Women and Cervical Cancer Screening: Decisional Balance and Self-Efficacy.

BACKGROUND: Latina women in the United States have greater cervical cancer mortality rates than non-Latina women because of their low rates of Papanicolau (Pap) smear screening. OBJECTIVES: The purpose of this article is to assess differences in perceived benefits, perceived barriers, and self-efficacy among Latina women to obtain Pap smears using the framework of the Transtheoretical Model. METHODS: A descriptive design with a snowball sample was used. The researchers assessed demographics, three perceived benefits, 12 barriers, and seven self-efficacy measures for 121 Latina women in northern Nevada. FINDINGS: Participants in precontemplation and relapse perceived greater barriers than those in action and maintenance for three items.

Application of the Transtheoretical Model to Cervical Cancer Screening in Latina Women.

This study examined the relationship between the intention to receive Pap tests for cervical cancer screening, as related to the transtheoretical model of behavior change, and self-efficacy, and perceived barriers and benefits among Latina women. A sample of 121 Latina women recruited from a University campus completed validated questionnaires. Over half the participants (62 %) reported engaging in regular cervical screening. The greatest self-efficacy scores were observed among women in the action/maintenance phase, and the least self-efficacy was observed among women in the no-intention phases of behavior change. There was also a gradient in perceived barriers and the stages of change, women in precontemplative/relapse perceived significantly higher barriers than those in contemplation/preparation and action/maintenance. This study identifies a high-risk group of Latina women and demonstrates a need for culturally targeted Pap screening interventions using validated and theoretically driven behavior change interventions focusing on perceived barriers and benefits, and self-efficacy.

A Comparison of HIV Knowledge, Attitudes, and Sources of STI Information Between Female and Male College Students in Taiwan.

Taiwan withdrew from the United Nations in 1971, which led to missed opportunities for participating in global HIV/AIDS programs and made Taiwan more vulnerable to HIV. Employing a questionnaire of 996 college students in Taiwan, the authors assessed and compared female and male HIV/AIDS-related knowledge, attitudes, and sources of HIV/sexually transmitted infections (STI) information. Students reported moderate knowledge and attitudes. Females had more positive attitudes toward people with HIV/AIDS than males. Most participants reported learning about HIV and STIs from traditional media, school teachers, and the Internet. We suggest evidence-based educational interventions for students should include targeted electronic and cultural awareness strategies.

Evidence-based HIV pilot program for Chinese college students: Differences by gender.

This study explored gender differences in the effectiveness of the translated VOICES (Video Opportunities for Condom Education and Safer Sex) intervention on the condom use intention, perceived benefits and barriers to condom use, condom use self-efficacy, and HIV/AIDS knowledge among Chinese students in a US university. We utilized a pretest/post-test quasi-experimental design and recruited 67 Chinese students at the local university. Participants viewed a 20-min video with Chinese subtitles, attended one 25-min small group discussion and condom interactive educational activity. Female participants showed significantly greater mean scores of perceived benefits and condom use self-efficacy, in comparison with male participants. Female participants also reported significantly higher scores than male participants in five of the perceived benefits items and one self-efficacy item. These study results provide important information for developing more differentiated intervention strategies specific to gender for HIV and STI education programs.
