Rotavirus vaccination rate disparities seen among infants with acute gastroenteritis in Georgia.
The purpose of this study was to determine possible disparities and socio-economic differences in RV vaccination rates. The study conclude that racial disparities and socio-economic differences are not determinants in rotavirus vaccination rates; however, age and ethnicity have an effect on RV vaccine status.

Simulating the impact of crime on African American women's physical activity and obesity.
The objective of this study was to quantify the impact of crime on physical activity location accessibility, leisure-time physical activity (LTPA), and obesity among African American women. The study’s simulations showed that crime may serve as a barrier to LTPA. Reducing crime and increasing propensity to exercise through multilevel interventions may promote greater than linear declines in obesity prevalence.

Factors associated with achieving a body mass index of less than 30 after bariatric surgery.
This study identified predictors for achieving a BMI of less than 30 after bariatric surgery. Patients who had a sleeve gastrectomy, gastric bypass, or duodenal switch were more likely to achieve a BMI of less than 30 compared with those who underwent adjustable gastric banding. Only 8.5 percent of patients with a BMI greater than 50 achieved a BMI of less than 30 after bariatric surgery.

Expectancy and achievement gaps in educational attainment and subsequent adverse health effects among adolescents with and without chronic medical conditions.
This study sought to investigate educational aspirations, expectations, and attainment among youth with and without chronic conditions and to determine if these relationships mediated subsequent disparities in health and well-being. Findings suggest an important risk mechanism through which youth with chronic medical conditions may acquire socioeconomic disadvantage as they develop and progress through educational settings.

Variation in functional status after hip fracture: facility and regional influence on mobility and self-care.
Little is known about variation in functional outcomes after postacute rehabilitation for patients with hip fracture. The researchers examined variation in mobility and self-care after hip fracture rehabilitation across inpatient rehabilitation facilities (IRFs), hospital referral regions (HRRs) and states. Variation in functional status following postacute hip fracture rehabilitation appears to occur primarily at the level of facilities rather than geographic location.

The modified frailty index to predict morbidity and mortality for retroperitoneal sarcoma resections.
The researchers performed a retrospective analysis of patients with a diagnosis of primary malignant retroperitoneal neoplasm who underwent surgical resection. The modified frailty index (mFI) was calculated according to standard published methods. Their data demonstrate that the majority of patients undergoing retroperitoneal sarcoma resections have few, if any, comorbidities. The mFI was a limited predictor of overall and serious complications and was not a significant predictor of mortality.

Implications of variation in the relationships between beneficiary characteristics and Medicare Advantage CAHPS measures.
The researchers studied how differences in quality score adjustments across Medicare Advantage contracts change comparisons for individuals and contracts. They found that, for average consumers, standard adjustment is sufficient to represent variation in contract quality standardized to a common population. For people with characteristics far from average, personalized reporting using their characteristics and contract-specific coefficients can substantially change the expected quality measures across contracts.

Educational attainment and health outcomes: data from the Medical Expenditures Panel Survey.
This study explored the extent to which health care utilization and health risk-taking can explain the education-health gradient above and beyond what can be explained by previously examined mediators such as age, race, and poverty status. It found systematic graded relationships between educational attainment and health including, SF-12 PCS scores, self-rated health, and activity limitations. Education was associated with more office visits and outpatient visits and less risk tolerance.

Racial differences and disparities in osteoporosis-related bone health: results from the PAADRN randomized controlled trial.
The researchers examined whether providing dual-energy x-ray absorptiometry (DXA) test results directly to patients might reduce or eliminate racial differences in osteoporosis-related health care. They found that black women were still less likely to know their actual DXA result and less likely to be on guideline-concordant therapy, but black women had greater patient activation.

Racial disparity in life expectancies and life years lost associated with multiple obesity-related chronic conditions.
This study investigated racial disparity in life expectancies (LEs) and life years lost associated with multiple obesity-related chronic conditions. It found that black individuals had higher risks of developing diabetes, hypertension, and stroke. This disparity in LE between white and black participants was largest in men age 40 to 49 with at least stroke: black men lived 3.12 years shorter than white men.

Disparities in chronic medical conditions in the Mid-South.
This study examined differences in socio-demographic characteristics and health behaviors relevant to chronic medical conditions (CMCs) in the Mid-South region (Alabama, Mississippi, Louisiana, Kentucky, Tennessee, and Arkansas), and identified subpopulations with increased burden of chronic disease. It concluded that in the Mid-South, race and gender disparities in the top five chronic conditions are more prominent among higher-income rather than lower-income individuals.

The prospective associations between self-efficacy and depressive symptoms from early to middle adolescence: a cross-lagged model.
This study investigated the bidirectional and prospective associations between depressive symptoms and academic, social and emotional self-efficacy from early to mid adolescence in a cross-lagged path model. It found that depressive symptoms predicted subsequent levels of academic and emotional self-efficacy on all time points, and social self-efficacy on one time point. Self-efficacy did not predict subsequent levels of depressive symptoms.

Survival gains from first-line systemic therapy in metastatic non-small cell lung cancer in the U.S., 1990-2015: progress and opportunities.
The objectives of this study were to quantify survival gains from 1990, when best supportive care only was standard, to 2015 and to estimate the impact of expanded use of new systemic therapies in clinically appropriate patients. By using simulation modeling to quantify metastatic non-small cell lung cancer survival gains from 1990-2015, the researchers estimated that the one-year survival proportion and mean per-patient survival increased by 14.1 percent and 4.2 months, respectively.

Sex differences in inflammatory markers and health status among young adults with acute myocardial infarction: results from the VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young Acute Myocardial Infarction Patients) Study.
This study assessed sex differences in post-acute myocardial infarction (AMI) inflammatory markers and whether such differences account for sex differences in 12-month health status, using data from 2219 adults with AMI, 18 to 55 years of age, in the United States. Overall, women had higher levels of inflammatory markers after AMI compared with men, and this remained statistically significant after multivariable adjustment.

Perceived discrimination and privilege in health care: the role of socioeconomic status and race.
This study examined how perceived racial privilege and perceived racial discrimination in health care varied with race and socioeconomic status (SES). It found that in whites, higher income and education contributed to increased perceptions of privileged treatment and decreased perceptions of discrimination. The pattern was reversed in blacks, who reported more discrimination and less privilege at higher income and education levels.

Sociodemographic patterns of chronic disease: how the mid-south region compares to the rest of the country.
This descriptive study examines sociodemographic differences in the distribution of chronic diseases and health-related behaviors in the Mid-South versus the rest of the U.S., identifying subgroups at increased risk of chronic disease. It finds that the Mid-South population had increased rates of chronic disease and worse health-related behaviors than the rest of the U.S. Mid-South blacks had the highest percentages of obesity, diabetes, high blood pressure, and stroke of all subgroups.

Systemic inflammation in midlife: race, socioeconomic status, and perceived discrimination.
This study investigates social determinants of systemic inflammation, focusing on race, SES, and perceived discrimination. Data on 884 white and 170 black participants were obtained from the Survey of Midlife in the U.S., a cross-sectional observational study combining survey measures, anthropometry, and biomarker assay. It suggests that inflammation-reducing interventions should focus on blacks and individuals facing socioeconomic disadvantages, especially low education.
