Impact of BMI on prevalence of dense breasts by race and ethnicity.
Researchers evaluated differences in body mass index (BMI) in relation to differences in dense breasts prevalence by race/ethnicity. Their results indicated that dense breasts were most prevalent among Asian women followed by non-Hispanic White, Hispanic, and Black women. Clinically important differences in breast density prevalence are present across racial/ethnic groups after accounting for age, menopausal status, and BMI. IMPACT: If breast density is the sole criterion used to notify women of dense breasts and discuss supplemental screening it may result in implementing inequitable screening strategies across racial/ethnic groups.

Racial variation in baseline characteristics and wait times among patients undergoing bariatric surgery.
The purpose of this study was to examine whether differences exist in baseline characteristics or access to care between white and non-white patients of bariatric surgery. The researchers utilized a statewide bariatric-specific data registry and assessed all patients of bariatric surgery who completed a baseline questionnaire prior to the operation and compared data among racial groups. A total of 73,141 patients were included with 25.5% self-identifying as non-white. Non-white males were the least represented group with 4% of all bariatric surgery cases performed. Despite having higher rates of college education, when compared to white patients non-white patients were more likely to be younger, disabled, and have Medicaid. Despite having higher rates of patients with a body mass index above 50 kg/m the median time from the first evaluation to surgery was longer among non-white patients (157 days vs. 127 days.) The study concluded that despite presenting with higher rates of severe obesity, when compared with white patients non-white patients of bariatric surgery are an extremely diverse group with greater socioeconomic disadvantages and longer wait times.

Effect of a culturally adapted behavioral intervention for Latino adults on weight loss over 2 years: a randomized clinical trial.
Identifying effective weight loss interventions for Latino adults at risk of diabetes is of critical public health importance. The purpose of this study was to determine whether a culturally adapted behavioral intervention for Latino adults was more effective than usual care for weight loss over 24 months. The investigators concluded that among Latino adults with high diabetes risk, a culturally adapted behavioral lifestyle intervention was effective for weight loss over 12 months but not 24 months.

The food environment in 3 neighborhoods in South Los Angeles, California: access, availability, quality, and marketing practices.
The authors developed a mapping component as part of a multilevel church-based intervention that used community-based participatory research to prevent obesity in African American and Latino churches in South Los Angeles. They developed neighborhood maps of local food environments and provided churches with standardized information on food access, availability, quality, and marketing practices. Including several tables as well as discussion, they stated that local food environment maps that are paired with data can inform community-based strategies to prevent obesity and food insecurity.

Church-based interventions to address obesity among African Americans and Latinos in the United States: a systematic review.
This systematic literature review examined the impact of multilevel church-based interventions to address racial/ethnic disparities in obesity in the US. The review identified 43 relevant articles using systematic review methods developed by the CDC’s Task Force on Community Preventive Services. Although 81% of the studies reported significant results, effective size was reported or could only be calculated in 56% of the cases. A lack of diversity among the samples was also found with few studies involving Latinos, men, young adults, or children. Few interventions were actually multilevel in nature or incorporated strategies at the church or community. Greater diversity is needed in future church-based interventions.

Elucidating the role of overweight and obesity in racial and ethnic disparities in cesarean delivery risk.
This study’s goal was to quantify the extent to which overweight and obesity explain cesarean delivery rates among women of different racial and ethnic backgrounds. Administrative records were used from New York City for 216,481 singleton, nulliparous births from 2008 to 2013. Risk ratios, risk differences, and population attributable fractions for associations between body mass index and cesarean, stratified by race and ethnicity was calculated. Black and Hispanic women had the highest cesarean rates attributable to obesity and overweight (17.4% and 14.6%) respectively.

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.

A comparative effectiveness education trial for lifestyle health behavior change in African Americans.
The authors of this study compared the effects of alternate behavioral interventions on obesity-related health behaviors by conducting a comparative effectiveness education trial in a community-based sample of 530 adult African Americans. The investigators suggest that education about risk factors for chronic disease and evidence-based strategies for health behavior change may be useful for addressing obesity-related behaviors among African Americans.

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.

Identifying the complexity of multiple risk factors for obesity among urban Latinas.
The prevalence of obesity is rising rapidly among Hispanics/Latinas. Researchers evaluated the prevalence of being obese or overweight and associated risk factors among 630 low-income, Latina women. They found that being obese was strongly associated with having hypertension, pre-hypertension, diabetes and moderate/moderately severe/severe depression. Women who reported that finding time was a barrier to physical activity were also more likely to be obese.

What can providers learn from childhood body mass index trajectories: a study of a large, safety-net clinical population.
The investigators described childhood weight gain using body mass index (BMI) z-score trajectories in a low-income urban safety-net population and identified among gender- and race/ethnicity-specific groups any trends for increased risk. They found that all gender and race/ethnicity subgroups showed increasing average BMI z-scores during childhood, with Hispanic boys and black girls showing the most significant increase during this observation period. They further found that many obese children were already overweight by age 3, and persistence of obesity after 3 years of age was high. They concluded that intervention before age 3 may be essential to curbing unhealthy weight trajectories.

Dyadic collaboration in shared health behavior change: the effects of a randomized trial to test a lifestyle intervention for high-risk Latinas.
The authors sought to evaluate the feasibility of a pilot, dyad-based lifestyle intervention, the Unidas por la Vida program, for improving weight loss and dietary intake among high-risk Mexican American mothers with Type 2 diabetes and their overweight/obese adult daughters. They found that, at 16 weeks, Unidas participants lost significantly more weight compared with the control participants, and intervention participants also were more likely to be eating foods with lower glycemic load and less saturated fat. They concluded that interventions that draw upon multiple people who share a health-risk have the potential to foster significant changes in lifestyle behaviors and in social network members' health-related involvement.
