Wide pulse pressure is an independent predictor of cardiovascular mortality in Puerto Rican men.

BACKGROUND AND AIM: Emerging evidence suggests that pulse pressure is an independent predictor of risk for cardiovascular mortality. New studies in diverse populations are needed to further establish the applicability of this finding. Thus, the purpose of this study is to examine the relationship between pulse pressure and cardiovascular mortality in a cohort of Puerto Rican men after 12 years of follow-up. METHODS AND RESULTS: The Puerto Rico Heart Health Program is a study of coronary disease risk factors in men aged 35-79 years at baseline who had an initial examination during the years 1962-1965. It was attended by 9824 subjects representing 80% of the total age-specific male residents in 4 rural and 3 urban areas of Puerto Rico. Cardiovascular risk factors including systolic and diastolic blood pressures were monitored prospectively. This study includes 9106 men free of overt CHD at baseline who were stratified by quartiles of pulse pressure in mmHg: quartile 1, or=57. The odds ratio of cardiovascular mortality was calculated using logistic regression analysis. After adjusting for age, education, smoking status, hypercholesterolemic status, physical activity, diabetic status and mean arterial pressure, we found that those in the highest quartile of pulse pressure (pulse pressure>=57) had significantly higher cardiovascular mortality than those in the lowest quartile (reference group) (OR=1.38 95% CI=1.01-1.88). CONCLUSION: Our findings showed that a wide pulse pressure is independently associated with cardiovascular mortality in this group of Puerto Rican men.

A birth records analysis of the Maternal Infant Health Advocate Service program: a paraprofessional intervention aimed at addressing infant mortality in African Americans.

Recognizing that no single intervention was likely to eliminate racial disparities, the Genesee County REACH 2010 partnership, utilizing both "bench" science and "trench" knowledge, developed 13 broad-based, multi-faceted interventions to eliminate infant mortality. This article provides highlights from a recent birth records comparison analysis of the Maternal Infant Health Advocate Service (MIHAS) intervention, and is solely based on the records of 111 MIHAS clients, and a random sample of 350 African-American women residing in Flint, Michigan. The MIHAS clients were more likely than the comparison sample not to have graduated from high school (56% vs 35%, respectively, P<.0001). The MIHAS clients were more likely to report at least some smoking during pregnancy (20% vs 15%, respectively, P<.05). However, after controlling for age and education, these results were no longer statistically significant. In terms of birth outcomes, the comparative odds of MIHAS clients delivering a low birth-weight infant are 1.124 (95% CI: 0.620-2.038); the odds of their delivering an infant at 37 weeks or earlier are 1.032 (0.609-1.749). Although the MIHAS clients did not have statistically better birth outcomes than those of the general African-American population in Flint, the MIHAS clients did not demonstrate the outcomes one would expect, given their higher level of risk. Based on this analysis, the MIHAS intervention may have brought its clients "up to par" with the general community on several birth outcomes.

The relationship of physical activity and body weight with all-cause mortality: results from the Puerto Rico Heart Health Program.

PURPOSE: To study the relationship of physical activity and obesity with all-cause mortality in Puerto Rican Men. METHODS: The Puerto Rico Heart Health Program collected physical activity and anthropometric measurements in 9,824 men between 1962 and 1965. After excluding those with known coronary heart disease at baseline, and those who died within the first three years of the study we analyzed the data for the relationship between physical activity and overweight status to all-cause mortality in 9,136 men. We stratified our participants by quartiles of physical activity. Participants were classified into four categories of body weight: underweight (BMI < 18.5), healthy weight (BMI =18.5-24.9), overweight (BMI = 25-29.9), and obese (BMI = 30+). RESULTS: After adjusting for age, education, smoking status, hypertension status, hypercholesterolemic status, urban/rural residence, and overweight status, physical activity was independently related to all-cause mortality. All-cause mortality was lower in those in quartile 2 (OR = 0.68, CI = 0.58-0.79) than quartile 1 (reference, sedentary group). Mortality among those in quartile 3 and 4 (0.63, CI = 0.54-0.75; and 0.55, CI = 0.46-0.65, respectively) were also significantly lower than those observed in quartile 1, but not significantly lower than those observed in quartile 2. Furthermore, within every category of body weight, those who were most active had significantly lower odds ratio of all-cause mortality. CONCLUSION: Our findings support the current recommendation that some physical activity is better than none, in protecting against all-cause mortality. The benefits of an active lifestyle are independent of body weight and that overweight and obese Puerto Rican men who are physically active experienced significant reductions in all-cause mortality compared with their sedentary counterparts.

An evaluation of the asthma intervention of the New York State Healthy Neighborhoods Program.

BACKGROUND: The Healthy Neighborhoods Programs (HNP) are funded by the Federal Preventive Health and Health Services block grants and administered by the New State Department of Health (NYSDOH). Eight county and local health departments are funded for 3 years for a total of $1.25 million per year to target households at risk for environmental health and safety hazards. The HNP asthma intervention uses home visits to identify asthmatics, assess asthma morbidity and management, and identify environmental asthma triggers. Outreach workers provide education about asthma, referrals, and controls for asthma triggers. The purpose of this evaluation was to assess the impact of the HNP asthma intervention for the 1997-1999 funding cycle and for the first year of the 2000-2002 funding cycle. Because of changes in reporting requirements across the funding cycles, the findings for 1997-1999 and 2000 were analyzed separately. METHODS: We analyzed one final outcome measure, the rate of self-reported hospitalizations (admissions and emergency room visits), and three intermediate outcome measures (the percent of homes with cockroaches, the percent of asthmatics with a written management plan, and the percent of asthmatics using a peak flow meter). We also estimated the net savings resulting from a reduction in hospital admissions due to asthma. RESULTS: For the 1997-1999 funding cycle, the average hospitalization rate was 86 hospitalizations per 100 asthmatics per year at the intervention visit (i.e., the baseline rate) and 44.5 at the 1-year follow-up, a decrease of 48%. This was a larger decrease than the 24% average annual decrease in the baseline rates during the 3 years. In 2000, there were 96 hospitalizations per 100 asthmatics per year at the intervention visit and 25 at the one-year follow-up, a decrease of 74%. In 2000 there were about 110 fewer hospital admissions thought to be due to the net effects of the HNP intervention, resulting in an estimated gross savings of $905,300 (110 x $8,230). After subtracting the estimated cost of the asthma intervention ($624,683), the net savings were $280,617. CONCLUSION: New York's HNP seems to be succeeding in reducing asthma morbidity as measured by the hospitalization rates among asthmatics who have received the intervention. The HNP was successful in decreasing cockroach infestation in HNP homes. A standardized evaluation methodology and instrument are necessary to conduct a more rigorous evaluation of the HNP.

Health in the developing world: achieving the Millennium Development Goals.

The Millennium Development Goals depend critically on scaling up public health investments in developing countries. As a matter of urgency, developing-country governments must present detailed investment plans that are sufficiently ambitious to meet the goals, and the plans must be inserted into existing donor processes. Donor countries must keep the promises they have often reiterated of increased assistance, which they can easily afford, to help improve health in the developing countries and ensure stability for the whole world.

Genetic research and health disparities.

Alleviating health disparities in the United States is a goal with broad support. Medical research undertaken to achieve this goal typically adopts the well-established perspective that racial discrimination and poverty are the major contributors to unequal health status. However, the suggestion is increasingly made that genetic research also has a significant role to play in alleviating this problem, which likely overstates the importance of genetics as a factor in health disparities. Overemphasis on genetics as a major explanatory factor in health disparities could lead researchers to miss factors that contribute to disparities more substantially and may also reinforce racial stereotyping, which may contribute to disparities in the first place. Arguments that promote genetics research as a way to help alleviate health disparities are augmented by several factors, including research funding initiatives and the distinct demographic patterns of health disparities in the United States.

A framework for improving health in cities: a discussion paper.

This paper considers health in cities from the perspective of complex adaptive systems. This approach has a number of important implications for intervention that do not emerge in traditional accounts of cities and health. The paper reviews various accounts of the nature of cities and of health as well as the traditional urban health and Healthy Cities movements. It then provides a framework for intervention and tests it against an actual case study. It concludes that a complex adaptive systems framework opens up fresh possibilities for improving health in urban contexts.

An overview of sexually transmitted infections among adolescents.

Half of all United States high school students are sexually experienced. Female adolescents bear the highest rates of many STIs. Many adolescents infected with STIs report no symptoms suggestive of their infections. Health care providers who see adolescents should be poised to implement effective STI control through risk assessment, disease screening, and CDC-recommended treatment and prevention counseling.

Sodium intake among people with normal and high blood pressure.

BACKGROUND: The American Heart Association recommends no more than 2400 mg of sodium intake per day for healthy adults. Healthy People 2010 goals are to increase the proportion of persons who consume 2400 mg or less of sodium daily. We examined daily sodium intake among people with and without high blood pressure. METHODS: We used data for participants aged > or = 20 years from the 1999-2000 National Health and Nutrition Examination Survey. Of 4011 participants included in this analysis, 1673 were identified as hypertensive by self report, with systolic blood pressure > or = 140 mm Hg or diastolic blood pressure > or = 90 mm Hg. Dietary sodium intake was computed from foods and beverages consumed during the 24 hours prior to interview. RESULTS: Mean sodium intake among participants with and without high blood pressure was 3330 mg/day and 3600 mg/day (geometric means, 2885 mg/day and 3146 mg/day), respectively. The difference between the two groups, using log-transformed sodium intake, was statistically significant (p<0.001). Adjustment for age, gender, race/ethnicity, education, smoking, total caloric intake, physical activity, and body mass index resulted in a smaller but significant difference (2992 mg/day and 3089 mg/day, p<0.05). No difference in sodium intake was observed by prescription medication use or advice to reduce sodium among hypertensive participants. CONCLUSIONS: Although participants with hypertension reported lower intake of dietary sodium than those with normal blood pressure, daily intake of sodium was much higher than the recommendations in both groups. Increased efforts are needed to reduce sodium intake to achieve Healthy People 2010 goals.

Cardiovascular health among American Indians and Alaska Natives: successes, challenges, and potentials.

With low rates of the risk factors for cardiovascular disease as recently as 40 years ago, the rates of cardiovascular disease (CVD) in American Indians and Alaska Natives were exceedingly low. Despite recent large-scale efforts to eliminate health disparities in ethnic and minority populations, the impact among American Indian and Alaska Natives to date has been relatively limited. Indeed, over the past several decades the incidence and prevalence of cardiovascular risk factors has risen significantly, including the development of an epidemic of diabetes. Evidence suggests that these higher rates of cardiovascular risk factors, including tobacco abuse, diabetes, high blood pressure, and elevated cholesterol levels, may be placing an inordinate burden of cardiovascular disease on the American Indian and Alaska Native population. The rates of heart disease and stroke among American Indians and Alaska Natives are now higher than in the general U.S. population as well as in U.S. whites. Recent evaluations suggest that these rates are also higher than among other ethnic or racial populations in the United States. Additionally, American Indians and Alaska Natives have been found to have a substantially higher proportion of premature death from heart disease when compared with other ethnic and racial populations. A number of recent prevention initiatives and focused clinical efforts are making promising strides toward reduced disparities in cardiovascular health with primordial, primary, and secondary cardiovascular prevention efforts along with enhanced early identification and therapeutic intervention for more favorable cardiovascular outcomes in the future. In order to reach our goals of heart-healthy and stroke-free American Indians and Alaska Natives, implementation of an aggressive, reasonably resourced, systemic plan of coordinated health promotion, risk reduction, and disease control efforts are necessary, with appropriate policy and legislative support.
