Factors associated with ever use of mammography in a limited resource setting. A mixed methods study.

OBJECTIVE: To evaluate facilitators and barriers influencing mammography screening participation among women. DESIGN: Mixed methods study. SETTING: Three hospital catchment areas in Hidalgo, Mexico. PARTICIPANTS: Four hundred and fifty-five women aged 40-69 years. INTERVENTION: Three hundred and eighty women completed a survey about knowledge, beliefs and perceptions about breast cancer screening, and 75 women participated in semi-structured, in-person interviews. Survey data were analyzed using logistic regression; semi-structured interviews were transcribed and analyzed using elements of the grounded theory method. MAIN OUTCOME MEASURE: Women were categorized as never having had mammography or having had at least one mammogram in the past. RESULTS: From survey data, having had a Pap in the past year was associated with ever having had breast screening (odds ratio = 2.15; 95% confidence interval 1.30-3.54). Compared with never-screened women, ever-screened women had better knowledge of Mexican recommendations for the frequency of mammography screening (49.5% vs 31.7% P < 0.001). A higher percentage of never-screened women perceived that a mammography was a painful procedure (44.5% vs 33.8%; P < 0.001) and feared receiving bad news (38.4% vs 22.2%; P < 0.001) compared with ever-screened women. Women who participated in semi-structured, in-person interviews expressed a lack of knowledge about Mexican standard mammographic screening recommendations for age for starting mammography and its recommended frequency. Women insured under the 'Opportunities' health insurance program said that they are referred to receive Pap tests and mammography. CONCLUSIONS: Local strategies to reduce mammogram-related pain and fear of bad news should work in tandem with national programs to increase access to screening.

Knowledge and recommendations regarding breast cancer early screening in an upper middle income country: Primary and secondary health care professionals.

OBJECTIVE: To compare the current breast cancer prevention and control Mexican standard with recommendations that health care professionals provide to women for breast self-exams, clinical breast exams and mammography, as well as health care professional knowledge of the risk factors for and main clinical signs of the disease. METHODS: In 2012, using a cross-sectional design, trained interviewers surveyed health care providers in a sample of 798 medical units, of which 756 corresponded to the first and second levels of medical care. One health care professional from each unit was interviewed for the study. The sampling method was systematic and representative of the national and regional levels. Relative frequencies and 95% confidence intervals (CI) were obtained using the weighting factor assigned to each medical unit. RESULTS: Regarding the indicator about recommendations provided to the population regarding early screening for and risk factors and clinical signs of breast cancer, the average number of health care professional responses in accordance with the Mexican standard was 10.7 (95% CI 10.0-11.4) out of a maximum of 28 points, which corresponds to an average rate of 38.2% of responses (95% CI 35.6-40.8). The percentage of correct answers increased in all areas of breast exam knowledge as training hours in the previous year increased. CONCLUSIONS: Health care professionals are unaware of the current standards on breast cancer; therefore, these recommendations are not routinely translated into health care practice, which is a barrier to increasing the coverage of screening programs in health care services.

Gender, body mass index and socio-demographic variables associated with knowledge about type 2 diabetes mellitus among 13,293 Mexican students.

The main aim of this study was to evaluate correlates of the knowledge Mexican young people have about type 2 diabetes mellitus (DM) risk and prevention. We developed a cross-sectional study in public schools in Morelos, in central Mexico during 1998-1999 in 13,293 students (11-24 years). We determined body mass index (BMI) with anthropometric measurements (height and weight). Using questionnaire data, we constructed a DM knowledge-based scale. Statistical analysis was done using an ordinal, logistic regression model. Only 1.6% of the students (95%CI = 1.4-1.8) had high DM knowledge levels; 85.6% (95%CI = 84.9-86.1) had low levels. The factors with the strongest associations with high levels of knowledge about type 2 DM among the Mexican students in this study were: being in high school or at university (vs. junior high), urban residence, higher socio-economic level, and BMI indicating overweight or obesity. Other socio-demographic factors correlated with high levels of knowledge about the disease, but with slightly weaker associations, included female gender, higher age, higher academic achievement (grades) and higher education level of the student's mother. While young men who were overweight or obese were 2.6 and 3.4 times more likely to have high levels of knowledge about DM (95%CI = 1.9-3.6 and 2.1-5.5, respectively), young women who were overweight or obese were only 1.4 and 1.1 times more likely to have high knowledge about DM (95%CI = 1.0-1.9 and 0.6-1.8, respectively). Mexican young people have limited knowledge about DM, although this chronic disease is increasingly common in Mexico as in many other countries.

Perceptions of nurses with regard to doctor-patient communication.

The objective of this study was to evaluate nurses' perceptions of communication between doctors and patients with cancer, AIDS and rheumatoid arthritis. A cross-sectional study was conducted with 741 nurses in 12 hospitals. Nurses received a self-questionnaire that included questions on personal value and attitudes. The answers were used in constructing affective variables (religious beliefs, attitude towards death, paternalism). The prevalence of explicit communication in 'nurse perception of doctor-patient communication' in the case of cancer was 4.5%, with AIDS 30%, and with rheumatoid arthritis 41.8%. When the value of communication was evaluated, it became evident that the likelihood of a nurse perceiving explicit communication in reference to a diagnosis of cancer was 6.5 time greater when communication was considered to be of greater value (CI 95% 2.6-6.6). For nurses who accept the possibility of death, the likelihood of perceiving explicit communication in the case of AIDs was 7.4 times greater than for nurses who deny this possibility (CI 95% 3.7-14.7), and when nurses displayed a deeply religious attitude, the likelihood of perceiving explicit communication was 80% greater than for nurses without this attitude (CI 95% 1.1-2.9). Nurses participate actively in the process of attending to patients with cancer and other disabling illnesses. Thus, there is a need for health professionals who provide compassionate attention, which will improve the various interrelationships between nurses and patients.
