Racial Disparities in Adverse Cardiovascular Outcomes After a Myocardial Infarction in Young or Middle-Aged Patients.

Background Black patients tend to develop coronary artery disease at a younger age than other groups. Previous data on racial disparities in outcomes of myocardial infarction (MI) have been inconsistent and limited to older populations. Our objective was to investigate racial differences in the outcome of MI among young and middle-aged patients and the role played by socioeconomic, psychosocial, and clinical differences. Methods and Results We studied 313 participants (65% non-Hispanic Black) <61 years old hospitalized for confirmed type 1 MI at Emory-affiliated hospitals and followed them for 5 years. We used Cox proportional-hazard models to estimate the association of race with a composite end point of recurrent MI, stroke, heart failure, or cardiovascular death after adjusting for demographic, socioeceonomic status, psychological, and clinical risk factors. The mean age was 50 years, and 50% were women. Compared with non-Black patients, Black patients had lower socioeconomic status and more clinical and psychosocial risk factors but less angiographic coronary artery disease. The 5-year incidence of cardiovascular events was higher in Black (35%) compared to non-Black patients (19%): hazard ratio (HR) 2.1, 95% CI, 1.3 to 3.6. Adjustment for socioeconomic status weakened the association (HR 1.3, 95% CI, 0.8-2.4) more than adjustment for clinical and psychological risk factors. A lower income explained 46% of the race-related disparity in outcome. Conclusions Among young and middle-aged adult survivors of an MI, Black patients have a 2-fold higher risk of adverse outcomes, which is largely driven by upstream socioeconomic factors rather than downstream psychological and clinical risk factors.

A modified physiological strain index for workplace-based assessment of heat strain experienced by agricultural workers.

BACKGROUND: As global temperatures rise, increasing numbers of individuals will work in hot environments. Interventions to protect their health are critical, as are reliable methods to measure the physiological strain experienced from heat exposure. The physiological strain index (PSI) is a measure of heat strain that relies on heart rate and core temperature but is challenging to calculate in a real-world occupational setting. METHODS: We modified the PSI for use in field settings where resting temperature and heart rate are not available and used the modified physiological strain index (mPSI) to describe risk factors for high heat strain (mPSI ≥ 7) experienced by agricultural workers in Florida during the summers of 2015 through 2017. mPSI was calculated for 221 workers, yielding 465 days of data. RESULTS: A higher heat index (ß = 0.185; 95% CI: 0.064, 0.307) and higher levels of physical activity at work (0.033; 95% CI: 0.017, 0.050) were associated with a higher maximum mPSI. More years worked in US agriculture (-0.041; 95% CI: -0.061, -0.020) were protective against a higher maximum mPSI. Out of 23 workdays that a participant experienced a maximum mPSI ≥ 7, 22 were also classified as strained by at least one other measure of high heat strain (core temperature [Tc] >38.5°C, sustained heart rate >(180 - age), and mean heart rate > 115 bpm). CONCLUSIONS: This study provides critical information on risk factors for elevated heat strain for agricultural workers and suggests a practical approach for using PSI in field-based settings.

Text4baby program: an opportunity to reach underserved pregnant and postpartum women?

Text4baby was launched in 2010 to promote healthy pregnancies and babies by the use of text messaging. The primary objective of this study was to assess factors related to the enrollment process and reception of text4baby. A prospective cohort study was conducted in two Women, Infant and Children clinics in Atlanta (April 2010-July 2011). Randomly selected pregnant and postpartum women (n = 468) were queried on cell phone use and instructed on text4baby enrollment. Self-enrollment issues were assessed at one-week follow-up (n = 351, 75.0 %), and message reception and reading patterns at two-month follow-up (n = 209, 44.7 %). Forty-two percent of the women had some college education and 82 % had household income <=$20,000. About half attempted text4baby self-enrollment (162/351), with enrollment success more likely among women with more education (80 % with some college vs. 62 % with less education), with household income above $10,000 (61 % < $10,000 vs. 83 % $10,001-$20,000 and 76 % > $20,000), and among women living in smaller households (77 % 1-3 members vs. 58 % > 3 members) (all p < 0.001). Among the 209 participants in the final follow-up contact, >90 % reported uninterrupted reception and regular reading of messages, and 88 % planned to continue using text4baby. Results also suggested that respondents who were younger (<26 year), less educated and had lower health literacy skills were more likely to have interrupted messages. Despite substantial interest in the text4baby program in an underserved population, innovative ways to help women with significant disadvantages enroll and receive uninterrupted messages are needed.

Physician practice variation in the pediatric emergency department and its impact on resource use and quality of care.

OBJECTIVE: To evaluate variation in case-mix adjusted resource use among pediatric emergency department (ED) physicians and its correlation with ED length of stay (LOS) and return rates. METHODS: Resource use patterns at 2 EDs for 36 academic physicians (163,669 patients at ED1) and 45 private physicians (289,199 patients at ED2) from 2003 to 2006 were abstracted for common laboratory tests, imaging studies, intravenous therapy (fluids/antibiotics), LOS and 72-hour return rate for discharged patients, and hospital admissions for all patients. Case-mix adjustment was based on triage acuity, diagnostic category, demographics, and temporal measures. OUTCOME MEASURES: (1) adjusted overall resource use for ED1 and ED2 physicians and (2) observed-to-expected ratios for ED1 physicians. RESULTS: Case-mix adjusted hospital admission rates among physicians varied nearly 3-fold (6.3%-18%) for ED1 and 8-fold (2.5%-19.4%) for ED2. Intravenous therapy use varied 2-fold (4.9%-10.4%) at ED1 and 3-fold (3.6%-11.4%) at ED2. Emergency department 2 physicians had an almost 2-fold (10.9%-20.6%) variation in imaging use. Variation in head computed tomography use was 2-fold (1.1%-2.5%) at ED1 and 5-fold (0.9%-4.8%) at ED2. Physicians had longer than expected LOS if they had higher than expected use of laboratory tests (r, 0.41; 95% confidence interval [CI], 0.09-0.65; P < 0.05) and imaging (r, 0.48; 95% CI, 0.17-0.69; P < 0.01). Return rate was not significantly correlated with resource use in any category. Physicians with higher than expected use of laboratory tests had higher than expected use of imaging (r, 0.62; 95% CI, 0.36-0.78; P < 0.001), head computed tomography (r, 0.49; 95% CI, 0.19-0.70; P < 0.01), and intravenous therapy (r, 0.51; 95% CI, 0.20-0.71; P < 0.01). CONCLUSIONS: Significant variation exists in physician use of common ED resources. Higher resource use was associated with increased LOS but did not reduce return to ED. Practice variation such as this may represent an opportunity to improve health care quality and decrease costs.

U.S. medical students' attitudes about patients' access to care.

OBJECTIVE: Accessing adequate medical services remains a major struggle for many Americans, but U.S. medical students' beliefs regarding access to care have not been thoroughly examined. METHODS: All medical students in the Class of 2003 at 16 U.S. schools were eligible to complete three questionnaires during their medical training: during freshman orientation, orientation to wards, and their senior year (n=2316, response rate=80.3%). Students responded to three questions about health care provision. RESULTS: Overall, 35% of students strongly agreed that "physicians have a responsibility to take care of patients regardless of their ability to pay;" only 5% disagreed. Only 8% disagreed that "access to basic health care is a fundamental human right." We found the same significant associations with opinions on access as we did with "responsibility to treat," although the associations tended to be stronger for access. Only 10% of students agreed that "Managed care, as it is now delivered, is a good way to deliver health care to the U.S. population." CONCLUSION: Most U.S. medical students support universal access to medical care, though variations in this support, its decline with additional years of medical education, and concerns about managed care are noteworthy, and have policy implications for America's health and health care workforce.

A Quantitative assessment of a 4-year intervention that improved patient counseling through improving medical student health.

OBJECTIVE: Despite efforts to produce healthier physicians and patients, there are no published experiments where health promotion interventions throughout medical school have been compared with a control group regarding the school environment, students' personal health practices, and students' patient counseling practices. DESIGN: Using the Class of 2002 as controls, we performed a 4-year pilot study of a personal health promotion intervention on the Class of 2003 at Emory University School of Medicine (EUSM). We focused on improving the actual and perceived healthfulness of the educational milieu, and on improving their personal and clinical practices about diet, tobacco, exercise, and alcohol use. Data were collected at freshman and ward orientations and during a senior rotation (n(controls) = 110, 109, 100 and n(treatment) = 114, 104, 106; all response rates greater than 90%). RESULTS: Students receiving the intervention perceived EUSM as a healthier environment than did control students. By senior year, control males reported twice the tobacco use reported by males in the intervention (43% vs 22%, P = .02), although they had previously reported very similar levels (31% vs 29%, P = .8). Diet, exercise, and tobacco counseling practices were positively related to the intervention; alcohol was inversely related to the intervention. CONCLUSIONS: In this pilot, compared with controls, the intervention positively affected medical students' perceptions of their school health promotion environment, reduced tobacco use among male students and, to some extent, improved their patient counseling practices. Such a medical school-based health promotion intervention shows promise and should be studied in a broader setting.

Self-report of quality of medical student health care.

OBJECTIVES: To summarise survey results for the quality of medical students' personal health care, characterise the results according to the demographics and career orientations of the students, and evaluate the relationship between the perceived quality of health care received and the degree of emphasis on prevention in the health care provided. METHODS: We carried out a cross-sectional study with 2316 medical students in the class of 2003 from 16 medical schools, surveyed at 3 points during their training. We used a self-administered questionnaire designed to assess personal health care and related variables in medical students. RESULTS: The majority (92%) reported receiving health care that was at least good, but only a minority (23%) said they received excellent health care. Half had a regular doctor. Health care quality was rated more highly at Year 1 orientation than at later timepoints by students who had a regular personal doctor, and especially by those with personal doctors who emphasised prevention. CONCLUSIONS: The majority of medical students perceived that they had received health care that was good or better, but most did not believe it was excellent. As the provision of preventive care is important to students, increasing the amount of preventive care provided to students may both increase their personal satisfaction with their health care and model good clinical preventive practices for them.

Personal and professional correlates of US medical students' vegetarianism.

OBJECTIVE: To determine prevalence and correlates of US medical students' self-identification as vegetarians. DESIGN: Medical students were anonymously surveyed via questionnaire three times: at freshmen orientation, orientation to wards, and during senior year. SUBJECTS: Medical students in the Class of 2003 (n=1,849) at 15 US medical schools (response rate 80%). OUTCOME MEASURES: We examined self-reported vegetarianism, abstinence from meat items on a food frequency questionnaire, and associations between students' vegetarianism and their health-related outcomes. STATISTICAL ANALYSES: Bivariate associations were tested with chi(2) tests. RESULTS: During medical school, 7.2% of students self-identified as vegetarians; this percentage declined over time. Those who were vegetarians for health reasons (66% of vegetarians) ate more fruits and vegetables than those who were vegetarians for nonhealth reasons (P=0.02). Vegetarians were more likely (P<0.01) than nonvegetarians to eat more fruits and vegetables (P=0.002); be women (P=0.009); be Hindu, Buddhist, or Seventh Day Adventist (P< or =0.0004); be politically liberal (P=0.007); have a body mass index < or =25 (P=0.008); or, as freshmen, to perceive nutrition counseling as highly relevant to their intended practices (P=0.007). Vegetarian students were no more likely to counsel patients about nutrition than were nonvegetarians. CONCLUSIONS: Prevalence of vegetarianism was higher among US medical students than among other US adults, although the prevalence declined during medical school. Medical students and physicians with healthful personal practices are more likely to encourage such behaviors in their patients, although the specific nutrition habit of vegetarianism among medical students was unassociated with their nutrition counseling practices.

Predictors of US medical students' prevention counseling practices.

OBJECTIVE: To understand predictors of medical students' prevention counseling practices. METHODS: We surveyed medical students (n=2316 individuals) in the Class of 2003 at freshman orientation, and again at entrance to wards and senior year in a nationally representative sample of 16 US medical schools (response rate=80.3%). MAIN OUTCOME MEASURES: Perceived relevance of prevention counseling and seniors' frequency of prevention counseling. RESULTS: Healthier personal practices (p<0.0001), intention to become a primary care practitioner (p=0.0007), and attending a medical school that encouraged healthy personal practices (p=0.002) significantly predicted the frequency with which seniors reported currently counseling patients about preventive interventions (using a validated measure). Perceived counseling relevance was also significantly predicted by intention to become a primary care practitioner (p<0.0001), attending a school that encouraged healthy personal practices (p=0.0007), being earlier in one's training (p<0.0001), more interested in prevention (p<0.0001), female (p<0.0001), non-White (p=0.007), and by having healthy personal practices (p=0.008). CONCLUSIONS: Several of the variables predicting physician counseling also predict US medical students' reporting counseling (especially personal health practices and specialty type). In addition, the avidity with which medical schools encourage students to be healthy significantly influences their reported patient counseling. These findings can give a fresh, evidence-based direction to help create physicians who counsel patients about prevention.

Preventing influenza: vaccine systems and practices in the Southeast.

OBJECTIVES: The purpose of this study was to determine from state and local health departments: (1) how they purchase, distribute, and fund influenza vaccine; (2) whether they experienced a shortage in 2003/04; (3) how the shortages were handled; and (4) how they prepared for distribution in 2004/05. METHODS: A web-based survey was completed from June to August 2004 in eight Southeastern states. RESULTS: Data were obtained from each state and 222 local health departments. Major differences between and within states were found with regard to purchasing, distributing, and funding influenza vaccine. Although the majority of health departments experienced periods of shortages in 2003/2004, surpluses of vaccine remained at the end of the season. There was little evidence of interaction between the public and private sectors to share vaccine resources in response to shortages. Tracking systems for redistribution of vaccine or follow-up were often not in place. Entering the 2004/05 season, 25% of states and 11% of counties were not developing any special procedures to deal with shortages beyond what was in place earlier. CONCLUSIONS: Better systems and funding are needed, especially for adult influenza vaccine delivery and for redistribution of influenza vaccine in response to shortages.

Validation of a brief diet survey instrument among medical students.

Our objective was to assess the reproducibility and accuracy of fat and of fruit and vegetable items on a 43-item food frequency questionnaire (FFQ) previously self-administered by students at 16 US medical schools. Five in-person, 24-hour recalls were administered between two FFQ administrations to 88 medical students. Reported fat intake decreased from the first (34.7%) to the second (33.1%) FFQ administration ( P <.001); the reproducibility correlation was r =0.63. Fat intake from recalls (28.4%) was lower than that from the FFQ (33.8%, P <.001). The Pearson correlation was r =0.36. Fruit and vegetable servings per day were 3.9 and 3.7 from the first and second FFQ, respectively ( P =.5); the reproducibility correlation was r =0.77. Fruit and vegetable servings were marginally higher from recalls (4.3) than from the FFQ (3.8, P =.06). The Pearson correlation for fruit and vegetable servings was r =0.50. This brief FFQ provides acceptably reproducible and valid estimates of fruit and vegetable servings per day among most groups of medical students, but overestimates fat as a percentage of energy intake.

Personal health promotion at US medical schools: a quantitative study and qualitative description of deans' and students' perceptions.

BACKGROUND: Prior literature has shown that physicians with healthy personal habits are more likely to encourage patients to adopt similar habits. However, despite the possibility that promoting medical student health might therefore efficiently improve patient outcomes, no one has studied whether such promotion happens in medical school. We therefore wished to describe both typical and outstanding personal health promotion environments experienced by students in U.S. medical schools. METHODS: We collected information through four different modalities: a literature review, written surveys of medical school deans and students, student and dean focus groups, and site visits at and interviews with medical schools with reportedly outstanding student health promotion programs. RESULTS: We found strong correlations between deans' and students' perceptions of their schools' health promotion environments, including consistent support of the idea of schools' encouraging healthy student behaviors, with less consistent follow-through by schools on this concept. Though students seemed to have thought little about the relationships between their own personal and clinical health promotion practices, deans felt strongly that faculty members should model healthy behaviors. CONCLUSIONS: Deans' support of the relationship between physicians' personal and clinical health practices, and concern about their institutions' acting on this relationship augurs well for the role of student health promotion in the future of medical education. Deans seem to understand their students' health environment, and believe it could and should be improved; if this is acted on, it could create important positive changes in medical education and in disease prevention.

Transgenerational persistence of education as a health risk: findings from the Women Physicians' Health Study.

OBJECTIVE: Whereas the effect of socioeconomic status (SES) on morbidity and mortality is well known, little is known about its transgenerational persistence. METHODS: We studied SES and health data from the U.S. Women Physicians' Health Study (WPHS). WPHS studied 4,501 women physicians, a group with relatively homogeneously high income, occupational prestige, and educational attainment. RESULTS: In logistic regression models controlling for age and ethnicity, those with better educated mothers ate more fruits and vegetables and were less likely to have a gun in their home; those with better educated fathers were more likely to have a regular physician. There was no significant difference by parents' educational levels in exercise habits, fat consumption, compliance with prevention recommendations, current health status, or history of smoking, hypertension, or dyslipidemia. CONCLUSIONS: Parents' (especially mothers') educational levels affect their adult children's health habits and outcomes, even if those adult children are physicians. However, at least among physicians, this differential is small after only one generation of improved SES.
