RESUMO

BACKGROUND: Behavioral models play a key role in identifying pathways to better health and provide a foundation for health promotion interventions. However, behavioral models based in epidemiological research may be limited in relevance and utility in practice. OBJECTIVES: We describe a participatory approach within a community-based participatory research partnership for integrating epidemiological and community perspectives into the application of the sociocultural resilience model (SRM). The SRM posits that cultural processes have a symbiotic relationship with health-promoting social processes, which contribute to the health advantages among Mexicanorigin and other Latinx populations. METHODS: Community action board members engaged with academic partners to interpret and apply the SRM to a community-clinical linkages intervention implemented in the context of three U.S.-Mexico border communities. In a two-day workshop, partners engaged in a series of iterative discussions to reach common definitions and measures for SRM constructs. RESULTS: Partners described daily cultural processes as the food they eat, how they communicate, and a collectivist approach to getting things done. For intervention activities, the partners opted for intergenerational storytelling, sharing of food, and artistic forms of expression. Partners included measures of cultural nuances such as border identity and the complexities that often arise from navigating bicultural norms. CONCLUSIONS: Collaborative approaches within community-based participatory research partnerships can facilitate the adaptation and measurement of conceptual health behavior models in community practice.

RESUMO

BACKGROUND: Community-clinical linkages (CCLs) connect public health organizations and health care providers to better support patients. Community health workers (CHWs), representatives from priority populations with special connections to their community, can lead CCLs. OBJECTIVES: Our objective was to learn about how to conduct a CHW-led CCL from the perspectives of those implementing the intervention. METHODS: We conducted focus groups with CHWs and their supervisors and regularly consulted community partners while coding and analyzing data. RESULTS: We learned that CHWs thrive when supported by peers, supervisors, institutions, and researchers. Supervisors- who are new to the CHW role-should consider seeking training in CHW professional development and performance evaluation. Focus group participants agreed that by balancing the strengths and weaknesses of their organization, CHW-led CCLs benefit patients because the collaboration helps them to better manage their health. CONCLUSIONS: Future CHW-led CCL practitioners should consider how to best institutionally support CHWs to maximize benefits for patients.

RESUMO

BACKGROUND: Latinos are currently the largest and fastest growing racial/ethnic group in the United States and have the lowest rates nationally of regular sources of primary care. The changing demographics of Latino populations have significant implications for the future health of the nation, particularly with respect to chronic disease. Community-based agencies and clinics alike have a long history of engaging community health workers (CHWs) to provide a broad range of tangible and emotional support strategies for Latinos with chronic diseases. In this paper, we present the protocol for a community intervention designed to evaluate the impact of CHWs in a Community-Clinical Linkage model to address chronic disease through innovative utilization of electronic health records (EHRs) and application of mixed methodologies. Linking Individual Needs to Community and Clinical Services (LINKS) is a 3-year, prospective matched observational study designed to examine the feasibility and impact of CHW-led Community-Clinical Linkages in reducing chronic disease risk and promoting emotional well-being among Latinos living in three U.S.-Mexico border communities. METHODS: The primary aim of LINKS is to create Community-Clinical Linkages between three community health centers and their respective county health departments in southern Arizona. Our primary analysis is to examine the impact of the intervention 6 to 12-months post program entry. We will assess chronic disease risk factors documented in the EHRs of participants versus matched non-participants. By using a prospective matched observational study design with EHRs, we have access to numerous potential comparators to evaluate the intervention effects. Secondary analyses include modeling within-group changes of extended research-collected measures. This approach enhances the overall evaluation with rich data on physical and emotional well-being and health behaviors of study participants that EHR systems do not collect in routine clinical practice. DISCUSSION: The LINKS intervention has practical implications for the development of Community-Clinical Linkage models. The collaborative and participatory approach in LINKS illustrates an innovative evaluation framework utilizing EHRs and mixed methods research-generated data collection. TRIAL REGISTRATION: This study protocol was retrospectively registered, approved, and made available on Clinicaltrials.gov by NCT03787485 as of December 20, 2018.

RESUMO

BACKGROUND: Considerable efforts have been undertaken in the United States to reduce cervical cancer incidence and mortality by increasing screening; however, disparities in screening rates continue to exist among certain racial and ethnic minority groups. The objective of the current study was to determine the effectiveness of a lay health worker-delivered intervention-AMIGAS (Ayudando a las Mujeres con Informacion, Guia, y Amor para su Salud [helping women with information, guidance, and love for their health])-to increase Papanicolaou (Pap) test screening among 3 populations of women of Mexican origin. METHODS: Six hundred thirteen women of Mexican origin in 3 treatment sites were randomized among 4 study arms: the full AMIGAS program with a video and a flip chart (n = 151), the AMIGAS program without the video (n = 154), the AMIGAS program without the flip chart (n = 155), and a usual care control group (n = 153). Six months after enrollment, women were surveyed and reported whether or not they had been screened. RESULTS: Women in any of the intervention arms were statistically significantly more likely to report being screened than those in the usual care group in both an intent-to-treat analysis and a per-protocol analysis. In the intent-to-treat analysis, 25% of women in the control group and 52% in the full AMIGAS program group reported having had Pap tests (P < .001); in the per-protocol analysis, the percentages were 29% and 62%, respectively (P < .001). CONCLUSIONS: AMIGAS was effective in increasing Pap test screening among women of Mexican descent when used in a 1-to-1 setting. Future research should compare the 1-on-1 intervention with the group-based intervention.

RESUMO

Epidemiologic studies addressing the association of alcohol consumption with breast cancer consistently suggest a modest association and a dose-response relationship. The epidemiologic evidence does not point to a single mechanism to explain the association, and several mechanisms have been proposed. Alcohol consumption is shown to increase levels of endogenous estrogens, known risk factors for breast cancer. This hypothesis is further supported by data showing that the alcohol-breast cancer association is limited to women with estrogen-receptor positive tumors. Products of alcohol metabolism are known to be toxic and are hypothesized to cause DNA modifications that lead to cancer. Recent research has focused on genes that influence the rate of alcohol metabolism, with genes that raise blood concentrations of acetaldehyde hypothesized to heighten breast cancer risk. Mounting evidence suggests that antioxidant intake(e.g.folate)mayreducealcohol-associatedbreast cancer risk, because it neutralizes reactive oxygen species, a second-stage product of alcohol metabolism. Diets lacking sufficient antioxidant intake, as a result, may further elevate the risk of breast cancer among alcohol consumers. Given that alcohol consumption is increasing worldwide and especially among women in countries of rapid economic growth, a greater understanding of the mechanisms underlying the known alcohol-breast cancer association is warranted.Avoiding overconsumption of alcohol is recommended, especially for women with known risk factors for breast cancer.

Diversos estudios epidemiológicos muestran la asociación del consumo de alcohol con el cáncer de mama de forma consistente, lo que sugiere una modesta asociación, y una relación de dosis-respuesta.La evidencia no apunta a un mecanismo único para explicar la asociación y varios mecanismos han sido propuestos. El consumo de alcohol incrementa los niveles endógenos de estrógeno, un riesgo conocido para cáncer de mama. Esta hipótesis es apoyada por información que muestra que la asociación entre el alcohol y el cáncer de mama está limitada a mujeres con tumores con receptores positivos de estrógeno. Es conocido que los derivados de la metabolización del alcohol son tóxicos, y se ha pensado que causan modificaciones en el DNA que llevan al cáncer. La investigación reciente se ha enfocado en genes que influencian la velocidad con la que se metaboliza el alcohol, y elevan las concentraciones de acetaldehído que se piensa puede aumentar el riesgo de cáncer de mama. La evidencia actual sugiere que la ingesta de antioxidantes (e.g. folato) puede reducirelriesgode cáncer asociadoalalcohol,porque neutraliza las especies reactivas de oxígeno, un producto de la segunda etapa del metabolismo del alcohol. Las dietas con ingesta insuficiente de antioxidantes,como resultado de esto, pueden elevar el riesgo de cáncer entre los consumidores de alcohol.Dado que el consumo de alcohol está incrementando en todo el mundo, especialmente en mujeres de países con rápido crecimiento económico, un mejor entendimiento de los mecanismos subyacentes a la asociación del cáncer de mama y el alcohol es necesario. Evitar el consumo excesivo es recomendado, especialmente para mujeres con factores de riesgo conocidos para cáncer de mama.

RESUMO

BACKGROUND: Breast cancer is the cancer with the highest incidence among women in Chile and in many Latin American countries. Breast cancer screening has very low compliance among Chilean women. METHODS: We compared the effects on mammography screening rates of standard care, of a low-intensity intervention based on mail contact, and of a high-intensity intervention based on mail plus telephone or personal contact. A random sample of 500 women with the age of 50 to 70 years registered at a community clinic in Santiago who had not had a mammogram in the past 2 years were randomly assigned to one of the three intervention groups. Six months after randomization, participants were re-evaluated for their compliance with mammography screening. The outcome was measured by self-report and by electronic clinical records. An intention to treat model was used to analyze the results. RESULTS: Between 92% and 93% of participants completed the study. Based on electronic records, mammography screening rates increased significantly from 6% in the control group to 51.8% in the low-intensity group and 70.1% in the high-intensity group. About 14% of participants in each group received opportunistic advice, 100% of participants in the low- and high-intensity groups received the mail contact, and 50% in the high-intensity group received a telephone or personal contact. CONCLUSION: A primary care intervention based on mail or brief personal contact could significantly improve mammogram screening rates. IMPACT: A relatively simple intervention could have a strong impact in breast cancer prevention in underserved communities.

RESUMO

BACKGROUND: Little is known about the relationship between alcohol intake and breast cancer risk among Mexican women. This association may be modified by folate and Vitamin B12. METHODS: A population-based case-control study conducted in Mexico recruited 1,000 incident breast cancer cases aged 35-69 and 1,074 controls matched on age, region, and health care system. In-person interviews were conducted to assess breast cancer risk factors and recent diet using a food frequency questionnaire. Conditional logistic regression models estimated adjusted odds ratios and 95% confidence intervals. RESULTS: Over one-half (57%) of cases and less than one-half of controls (45%) reported any lifetime alcohol consumption. Compared with never drinkers, women reporting ever drinking (Adjusted OR = 1.25, 95% CI = 0.99-1.58) had a greater odds of breast cancer. There was evidence for interaction in the association between ever consuming any alcohol and breast cancer by folate (p for interaction = 0.04) suggesting women with lower folate intake had a higher odds of breast cancer (Adjusted OR = 1.99, 95% CI = 1.26-3.16) compared to women with higher folate intake (OR = 1.12, 95% CI = 0.69-1.83). CONCLUSIONS: Our findings support evidence that any alcohol intake increases risk of breast cancer. Insufficient intake of folate may further elevate risk for developing breast cancer among women who consume alcohol.

RESUMO

BACKGROUND: Breast cancer is the leading cause of cancer among women in Chile and in many Latin American countries. Breast cancer screening is an effective strategy to reduce mortality, but it has a very low compliance among Chilean women. OBJECTIVE: To understand barriers and facilitators for breast cancer screening in a group of Chilean women aged 50-70. METHODS: Following the Predisposing, Enabling and Reinforcing (PRECEDE) framework, seven focus groups (N = 48 women) were conducted with women that have had diverse experiences with breast cancer and screening practices. Information was collected using field notes and audio and video recording. Following the grounded theory model, a sequential process of open, axial and selective coding was used for the information analysis. Atlas ti 5.5 software was used for coding and segmenting the data obtained from the interviews. RESULTS: The presence of symptoms and/or the finding of lumps through breast self-examination (BSE) were the main predisposing factors for getting a mammogram. Secrecy, embarrassment and fatalism about breast cancer were significant cultural factors that influenced the decision to seek mammogram screening. Confidence in medical staff and dignity in the treatment at the clinic were important enabling factors. The main reinforcing factors for getting the test were a sense of fulfilment by doing something good for themselves and getting timely information about the results. CONCLUSIONS: Primary health care providers should use culturally appropriate strategies to better inform women about the importance of mammography screening and the limitations of BSE for preventing advanced breast cancer.

RESUMO

This study explores barriers to and facilitators of breast cancer screening and how people in a woman's social network influence these screening behaviors. A total of 40 semi-structured qualitative interviews were conducted in rural Washington State (USA) among Mexican women aged 50 and over. Eligible women reported either having had a mammogram within the last two years, over two years ago, or never. We found that lack of health insurance, the perception that the mammogram is painful, and fear of finding cancer were cited as barriers to participation in mammography screening. Women who had lived in the US for a shorter period were more likely to report never having had a mammogram than women who had lived in the US for a longer period. Women often cited daughters and female friends as those from whom they received advice or encouragement to receive a mammogram. Few differences were found related to network size and mammography use among the groups. These findings may be useful in designing interventions to promote mammography use. Including daughters in intervention activities may help facilitate mammography use among Mexican women.

RESUMO

Chilean women have the highest smoking rates in Latin America. Prevalence in this population is about 40%. There are no national programs for smoking cessation at the primary care level. This study explores the feasibility and effectiveness of a brief counseling intervention targeted to women smokers of childbearing age who seek primary care in Santiago, Chile. A quasi-experimental design was used to compare the effect of an intervention based on the '5A' model developed by the National Cancer Institute in the United States and the standard care provided in two control clinics. Women smokers seeking care at the three primary care clinics were contacted during a 2 months period and offer to participate in the study. Sampling was stratified according to the age groups to ensure comparability between cohorts. Quotas were calculated for each age group. Participants were asked about their willingness to quit, self-efficacy, smoking behavior, addiction level as well as support received for smoking cessation. After 18 months of intervention all women were re-evaluated. A total of 773 women were recruited for the study; 76% of them completed the trial. Women smokers are characterized by a large percentage of light smokers with a low self-efficacy for quitting and with very low information on where and how to get assistance to quit. At study end, 15.2% of women reported quitting smoking at least for 1 month in the intervention clinic versus 7.8% in one of the control clinics (p < 0.05) and 14.6% in the second control clinic (p = NS). Over 70% of women in the intervention clinic were asked, assessed and received advice for quitting in comparison with <15% in the control clinics (p < 0.01). To conclude, a primary care intervention based on the '5A' model for smoking cessation is feasible and can have a significant effect in reducing smoking prevalence in this population.

RESUMO

BACKGROUND: Chile has one of the highest prevalence rate of smoking in the world. Brief counseling interventions for smoking cessation at the primary health care level are effective. Compliance with counseling intervention is strongly associated with beliefs and attitudes of the primary health care team that deliver it. The effectiveness of these interventions improve if they are applied to smoking populations with higher motivation of change and high self-efficacy for quitting. AIM: To study the smoking profile of a group of smoking women in Santiago and to identify beliefs and attitudes of the primary health care team members to implement smoking cessation interventions. MATERIAL AND METHODS: A cross-sectional design that included 306 women smokers attending two primary health care clinics in Santiago. Perceptions, beliefs and attitudes of 34 primary care team members from three clinics in Santiago were explored using a qualitative methodology. RESULTS: The study identified a subgroup of 18% of women highly motivated to quit (decisional stage of change) and a 58% with a high self-efficacy. Beliefs and attitudes of staff at the clinics were characterized by invisibility, ambivalence and fatalism regarding the effectiveness of smoking cessation interventions. CONCLUSIONS: There is a subgroup of smoking women with a high probability of quitting if they receive an appropriate counseling. Developing a systematic approach for smoking cessation intervention at the primary care setting in Chile should consider the invisibility, ambivalence and fatalism of primary health care team members towards this topic.

RESUMO

OBJECTIVE: To assess the smoking behaviors, beliefs about the risks of smoking, and exposure to ETS among adolescents in Juárez, Mexico. METHODS: A cross-sectional study was conducted with sixth-grade students (N=506), aged 11-13 years old, attending 6 randomly selected schools. Schools were classified by school setting and SES. RESULTS: Students attending a low SES school setting were more likely to have smoked (P < 0.01), be current smokers (P < 0.01), be exposed to ETS at home and in public (P < 0.01) than were students attending a middle or high SES school. CONCLUSION: Smoking interventions should target students attending school in low SES settings.

RESUMO

PURPOSE: The purpose of this study was to examine Mexican American knowledge, attitudes, and beliefs about colorectal cancer and barriers to receiving colorectal cancer screening exams. DESIGN: We developed an open-topic focus group schedule that addressed knowledge, attitudes, and beliefs about screening for colorectal cancer and identified cultural issues to be considered when developing educational interventions to increase screening participation. Focus groups were used to elicit participant responses. SETTING: Two small communities (colonias) along the US-Mexico border. SUBJECTS: Mexican Americans ages > or = 50 years. RESULTS: A total of 43 individuals (20 men and 23 women) participated in the focus groups, each of which lasted approximately 90 minutes. Few focus group participants had ever heard of colorectal cancer or specific screening exams to detect early forms of cancer. Participants identified cost of medical care and embarrassment about receiving colorectal exams as barriers to screening participation. Respondents commonly expressed fatalistic attitudes about their chances of recovering from cancer, some preferred not to know if they had cancer or believed that they would refuse treatment if diagnosed with cancer. Nevertheless, many participants noted that strong support from family and friends or a strong will would allow one to survive cancer. CONCLUSION: Interventions to improve participation in screening services for colorectal cancer should focus on reducing the influences of cost and embarrassment and improving levels of knowledge about colorectal cancer and the need for screening.

RESUMO

Regular physical activity is associated with a reduced risk of all-cause mortality, and mortality due to cardiovascular disease and cancer. Among adolescents, physical activity is associated with benefits in the prevention and control of emotional distress, and improvement of self-esteem. Countries in transitional epidemiological scenarios, such as Chile, need to develop effective strategies to improve physical activity as a way to face the epidemic of chronic diseases. The objective of this study was to evaluate the effects of a school-based physical activity program on physical fitness and mental health status of adolescents living in a low socioeconomic status area in Santiago, Chile. A quasi-experimental design was used to evaluate the effects of the program over one academic year. The study included 198 students aged 15 years old. Two ninth grade classes were randomly selected as the intervention group, with two classes of the same grade as controls. A social planning approach was used to develop the intervention. The program was designed and implemented based on student preferences, teachers' expertise and local resources. Changes in physiological and mental health status were assessed. After the intervention, maximum oxygen capacity achieved a significant increase of 8.5% in the intervention versus 1.8% in the control group (p < 0.0001). Speed and jump performance scores improved significantly more in the intervention versus the control group (p > 0.01). Anxiety score decreased 13.7% in the intervention group versus 2.8% in the control group (p < 0.01), and self-esteem score increased 2.3% in the intervention group and decreased 0.1% in the control group after the end of the program (p < 0.0001). No significant change was observed in the depressive score. Student participation and compliance with the program was > 80%. To conclude, a school-based program to improve physical activity in adolescents of low socioeconomic status, obtained a high level of participation and achieved significant benefits in terms of physical fitness and mental health status.

RESUMO

Acculturation is important to examine variables that differentiate members of ethnic groups so that interventions can be appropriately targeted. By using a population-based sample of Mexican-origin adults, we sought to validate an acculturation scale for Mexican-American populations. The acculturation instrument included eight items adapted from the Acculturation Rating Scale for Mexican Americans (ARSMA). By using principal component analysis, we calculated eigenvalues for the eight items. The first principal component accounted for 66% of the variance. Language spoken most of the time, by itself, explained 62.4% of the variance of the full model, whereas birthplace, by itself, accounted for 74%. Slight increases in correlation values were observed beyond a four-item model that included language spoken most of the time, language thought, ethnic identity, and birthplace. Future studies should compare this scale with other multidimensional scales.

RESUMO

Hispanics in the United States have a disproportionately high risk for non-insulin-dependent diabetes mellitus (type 2 diabetes) compared with non-Hispanic whites. Little is known of the attitudes and beliefs about diabetes in this group. Using data from six focus groups of 42 Mexican Americans (14 men and 28 women), we characterized perceptions about the causes of and treatments for type 2 diabetes. Many participants believed diabetes is caused by having a family history of the disease, eating a diet high in fat or sugar, and engaging in minimal exercise. Experiencing strong emotions such as fright (susto), intense anger (coraje), or sadness and depression (tristeza) was also thought to precipitate diabetes. Nearly all participants expressed the belief that it is important to follow doctors' recommendations for diet and exercise, oral medication or insulin; many also cited herbal therapies, such as prickly pear cactus (nopal) and aloe vera (savila) as effective treatments. These findings may be useful in designing interventions to reduce the burden of diabetes in Hispanic populations.

RESUMO

OBJECTIVE: To examine associations of diet with acculturation among Hispanic immigrants from Mexico to Washington state and to compare dietary patterns of Hispanic with non-Hispanic white residents. DESIGN: Data are part of the baseline assessment for a community-randomized cancer prevention trial. The Fat-Related Diet Habits questionnaire and the National 5-A-Day for Better Health program dietary assessment instruments were used to collect data on fat and fruit and vegetable intake, respectively. Data were also collected on demographic characteristics and acculturation status. SUBJECTS/SETTING: A total of 1,689 adult Hispanic and non-Hispanic white residents of 20 communities in the Yakima Valley, WA, completed in-person interviews. STATISTICAL ANALYSES PERFORMED: Mixed model regression analyses tested associations of acculturation with diet. These models compared the fat and the fruit and vegetable intake of Hispanics vs non-Hispanic white residents. Additional analyses compared the diets of highly acculturated Hispanics with low-acculturated Hispanics. All models included age, sex, income, and education and were also adjusted for the random effect of community. RESULTS: Dietary patterns varied by ethnicity and acculturation status. On average, compared with non-Hispanic white residents, Hispanics consumed one more serving of fruits and vegetables per day (P<.001). Dietary habits changed as Hispanics acculturated to the United States. Highly acculturated Hispanics ate fewer servings of fruits and vegetables per day compared with those not highly acculturated (P<.05). Highly acculturated Hispanics had slightly higher, but not statistically significant, scores on the Fat-Related Diet Habits questionnaire, which corresponds to a higher fat intake, compared with low-acculturated Hispanics. The early dietary changes made on acculturation included adding fat at the table to breads and potatoes. APPLICATIONS/CONCLUSIONS: Nutrition professionals should encourage their Hispanic clients to maintain their traditional dietary practices, such as a high intake of fruits and vegetables and eating bread and potatoes without added fat.
