From primary care to public health: using Problem-based Learning and the ecological model to teach public health to first year medical students.

We investigated whether a public health-oriented Problem-Based Learning case presented to first-year medical students conveyed 12 "Population Health Competencies for Medical Students," as recommended by the Association of American Medical Colleges and the Regional Medicine-Public Health Education Centers. A public health-oriented Problem-Based Learning case guided by the ecological model paradigm was developed and implemented among two groups of 8 students at the University of California, Berkeley-UCSF Joint Medical Program, in the Fall of 2010. Using directed content analysis, student-generated written reports were coded for the presence of the 12 population health content areas. Students generated a total of 29 reports, of which 20 (69%) contained information relevant to at least one of the 12 population health competencies. Each of the 12 content areas was addressed by at least one report. As physicians-in-training prepare to confront the challenges of integrating prevention and population health with clinical practice, Problem-Based Learning is a promising tool to enhance medical students' engagement with public health.

Patterns of tobacco-use behavior among Chinese smokers with medical conditions.

Understanding the characteristics of Chinese American smokers with medical conditions and factors associated with their tobacco-use behaviors will guide effective cessation programs. In 2008, the authors described socio-demographic profiles of Chinese smokers with medical conditions treated during the period 2002-2006, documented their tobacco-use behaviors (i.e., average daily cigarette use, nicotine dependence, and number of past-year quit attempts), and drew comparisons between subjects recruited from hospitals (IP) and ambulatory settings (OP). Compared to OP, IP were significantly older, less educated, less acculturated, and more likely to be retired. Of the two groups, IP had poorer disease profiles, smoked less (4.4 vs. 11.9 cigarettes per day), and had lower nicotine-addiction scores (5.5 vs. 6.7). There was no difference between groups in past-year quit attempts. After adjustments, the data revealed that being employed and OP was associated with higher average daily cigarette use; IP were less nicotine dependent than OP; and for both groups, years of smoking was negatively associated with past-year quit attempts. Our study suggests that, more than acculturation level, health status influences the Chinese smoker's level of cigarette use and nicotine addiction. Given the severity of their disease profiles, IP should be aggressively targeted for intervention, as they are more likely to be light smokers and to be less nicotine dependent than OP. Future tobacco treatment studies should pay attention to health status among smokers in health-care settings in order to provide a more accurate assessment of treatment needs and of barriers to successful smoking cessation.

Work time and 11-year progression of carotid atherosclerosis in middle-aged Finnish men.

INTRODUCTION: Studies of the relationship between work time and health have been inconclusive. Consequently, we sought to examine the effect of work time on progression of atherosclerosis. METHODS: This prospective study of 621 middle-aged Finnish men evaluated effects of baseline and repeat measures of work time on 11-year progression of ultrasonographically assessed carotid intima-media thickness (IMT) and interactions with cardiovascular disease. Multiple linear regression models adjusted for 21 biological, behavioral, and psychosocial risk factors RESULTS: Working 3 (minimum), 5 (medium), or 7 (maximum) days per week at baseline was associated with 23%, 31%, and 40% 11-year increases in IMT, respectively. The relative change ratio (RCR) at maximum vs minimum was 1.14 for baseline days worked per week and 1.10 for hours worked per year of follow-up. Significant interactions existed between cardiovascular disease and work time. Men with ischemic heart disease (IHD) who worked the maximum of 14.5 hours per day experienced a 69% increase in IMT compared with a 29% increase in men without IHD. The RCR ratio for IHD (RCRIHD/RCRno IHD) was 1.44 for hours per day. Similarly, the RCR ratio for baseline carotid artery stenosis was 1.29 for hours per day and 1.22 for hours per year. CONCLUSION: Increases in work time are positively associated with progression of carotid atherosclerosis in middle-aged men, especially in those with preexisting cardiovascular disease. Our findings are consistent with the hemodynamic theory of atherosclerosis.

The Chinese community smoking cessation project: a community sensitive intervention trial.

This paper describes (1) the design, methods and baseline data of the first smoking cessation clinical trial for Chinese Americans with medical conditions - Chinese Community Smoking Cessation Project (CCSCP); (2) the collaborative process between researchers and the Chinese community; and (3) the barriers and facilitators of implementing the study. CCSCP was a culturally tailored, randomized, smoking cessation trial testing the efficacy of an intensive (physician advice, in-person counseling with nicotine replacement therapy, 5 telephone calls) compared to a minimal (physician advice and self-help manual) intervention. The study applied a community-sensitive research method involving community members in all phases of the research process in San Francisco Bay Area during 2001-2007. CCSCP recruited 464 smokers from health care facilities (79%) located in Chinese neighborhoods and through Chinese language media (21%). Baseline assessments and interventions were conducted in-person using translated and tested questionnaire and intervention materials. The majority of the participants were men (91%) with a mean age of 58.3 years, foreign born (98%), with less than high school education (58%), spoke no English (42%) and in non-skilled or semi-skilled occupations (60%) with <$20,000 household income (51%). Participants smoked regularly on an average 38.6 +/- 17 years, smoked 9.1 +/- 8 cigarettes per day and 85% smoked daily. Cultural tailoring of recruitment methods and intervention design led to successful enrollment and retention of participants, overcoming barriers faced by the participants. Community sensitive collaborative process facilitated implementation of study protocol in community health care settings.

Characterization of systemic hypertension in the San Francisco Chinese community.

This report examines the prevalence of hypertension, its management and control, and the use of antihypertensive medication, diet, and exercise in Chinese adults residing in the San Francisco community. Blood pressure (BP) was measured objectively using an automated oscillometric Dinamap recorder on 708 Chinese adults (295 men and 413 women; age range from 19 to 98 years, mean 59.7), and hypertension, defined as BP >140/90 mm Hg and/or the use of antihypertensive medications, was found in 489 (69%), most of them immigrants from China. Although 202 patients (41%) received antihypertensive medications, only 28 (14%) achieved BP control (<140/90 mm Hg), and in examining the self-management of hypertension, it was found that only 45% of patients used low-sodium diets, and 49% performed regular exercises for > or = 30 minutes > or = 3 times weekly.

Adherence with hypertension care among Hmong Americans.

To assess contexts of adherence with hypertension care among Hmong Americans, in-person interviews were conducted with a convenience sample of 323 adults using culturally adapted survey instruments. The mean age of participants was 58 years; 91% had no education, and 86% spoke no English. Although more than 90% had health insurance and were treated with medications, the rate of blood pressure control was low (27%). A majority (> 90%) suffered from psychological distress, and 46% lived with physical illness. Over 50% reported nonadherence with hypertension care. Respondents who were 50 years of age or older, had no physical illness, did not know that hypertension was preventable, or believed that American medicine was too strong, were more likely to report nonadherence with proper medication consumption. Findings suggest that adherence was not due to lack of health care coverage; instead, it may be due to gaps in health services.
