MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Recent research has demonstrated the importance that neighborhood context has on life opportunity, health and well-being that can perpetuate across generations. A strongly defining factor that leads to differences in health outcomes across neighborhoods, such as differences in chronic disease, is the concurrent-uneven distribution of modifiable risk factors for chronic disease.

The main goal of our study was to characterize inequities in smoking, the leading risk factor for chronic disease, between neighborhoods in America’s 500 largest cities. To accomplish this aim we used first-of-its-kind data generated from the 500 Cities Project—a collaboration between Robert Wood Johnson Foundation and the US Centers for Disease Control and Prevention—representing the largest effort to provide small-area estimates of modifiable risk factors for chronic disease.

We found that inequities in smoking prevalence are greater within cities than between cities, are highest in the nation’s capital, and are linked to inequities in chronic disease outcomes. We also found that inequities in smoking were associated to inequities in neighborhood characteristics, including race, median household income and the number of tobacco retailers.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Local health departments are often evaluated on a nationwide or statewide basis, however, given diversity among counties that exists even at the state level, we felt there might be a better way to group health departments for evaluation.

In this study, we created county-level clusters using local characteristics most associated with the outcomes of interest, which were smoking, motor vehicle crash deaths, and obesity. We then compared county-level percentile rankings for the outcomes within sociodemographic peer clusters vs nationwide rankings. We identified 8 groups of counties with similar local characteristics.

Percentile ranks for the outcomes of interest often differed when counties were compared within their peer groups in comparison with a nationwide scale.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: This study is part of a larger body of research examining how literacy and decision making abilities in different areas of life can affect the health and well-being of older adults.

The main finding of this study is that a better ability to understand and utilize financial concepts was related to a lower risk of hospitalization in old age.

Over almost 2 years of follow-up, 30 percent of the 388 older men and women in this study were hospitalized at least once. A 4-point higher score on the scale of financial literacy, representing one standard deviation, was associated with about a 35 percent lower risk of hospitalization. This was after adjusting for a number of factors including physical and mental health indicators and income. The association appeared to be stronger for knowledge of financial concepts such as stocks and bonds, as opposed to the ability to perform numerical calculations. Additionally, the association was stronger for elective hospital admissions as opposed to emergency or urgent hospitalizations; this may support the notion that financial literacy is related to medical decision-making surrounding the decision to be hospitalized, such as which procedures are covered by Medicare.

Cancer Death Rates Higher in Rural America

MedicalResearch.com: What is the background for this study?

Response: This MMWR report is the first complete description of cancer incidence and mortality comparing rural and urban America.  From previous reports we know that rural residents are more likely to be older, have more comorbid conditions and participate in high risk behaviors that can lead to cancer. CDC researchers were interested in how these factors were related to new cancers and cancer deaths in rural counties compared to metropolitan counties.

Researchers found that rates of new cases for lung cancer, colorectal cancer, and cervical cancer were higher in rural America. In contrast, rural areas were found to have lower rates of new cancers of the female breast, and prostate. Rural counties had higher death rates from lung, colorectal, prostate, and cervical cancers.

Breast Cancer: Black Patients Had Fewer Sentinel Lymph Node Biopsies

MedicalResearch: What are the main findings of the study?

Dr. Black: This is a retrospective study from 2002 – 2007 using the SEER/Medicare database of over 31,000 women with node negative breast cancer evaluating the utilization of sentinel node biopsy (SNB) as it transitioned from an optional method for axillary staging to the standard of care instead of complete axillary lymph node dissection (ALND).  We found that SNB use increased each year in both white and black breast cancer patients throughout the study period.  However, SNB was less often performed in black patients (62.4%)compared to white patients (73.7%) and this disparity persisted through 2007 with a 12% difference.  Appropriate black patients more often had an ALND instead of the minimally invasive sentinel node biopsy which resulted in worse patient outcomes with higher lymphedema rates in black patients.  However, when black patients received the minimally invasive SNB, their rates of lymphedema were low and comparable to white patients who received SNB.

HIV Care Gaps Largest among African Americans and Young People

MedicalResearch.com: What are the main findings of the study?

Dr. Hall: Our research finds that, across all populations, far too few Americans with HIV receive the care they need to stay healthy and reduce risk of transmission. According to our research, gaps in care are the largest among African Americans and young people. Moving forward, improving care for all HIV-infected people will be critical to achieving the goal of an AIDS-free generation in America.

More specifically, some of the key findings of the study include:

  • Overall, only a quarter of all Americans with HIV have a suppressed viral load – meaning the level of HIV in their bodies is low enough to stay healthy and dramatically reduce the chance of transmitting to others.
  • By race/ethnicity, African-Americans and Hispanics or Latinos are less likely to be aware of their infection compared to whites.
  •  By age, younger Americans are less likely to be in ongoing care and have a suppressed viral load; HIV care and viral suppression generally improved with age. For example:
  • Fifteen percent of those aged 25-34 were virally suppressed, compared to 36 percent of those aged 55-64.
  • In terms of ongoing care, 28 percent of those 25-34 years old were retained in care, compared to 46 percent of those aged 55-64.
