Very low probability of attaining normal weight among obese people Over a nine-year period, the likelihood of obese people reaching normal weight is very low, according to new research from the American Journal of Public Health.

The UK-based study reviewed patient electronic medical records from the world’s largest primary care database, UK Clinical Practice Research Datalink. Researchers analyzed patterns of body mass index from 278,982 men and women over the age of 20. Specifically, the analysis which spanned from 2004 to 2014, focused on the proportion of patients that attained normal body weight and the proportion of patients that attained five percent weight loss annually. Patients receiving bariatric surgery were not included in the study sample.

Results from the study indicated that the annual chance of patients with simple obesity (BMI 30-35) attaining a normal body weight was 1 in 124 women and 1 in 210 men. The likelihood of attaining normal weight decreased as BMI increased in which 1 in 1290 morbidly obese men and 1 in 677 morbidly obese women attained normal weight annually. However, the probability for attaining a 5 percent decrease in BMI was 1 in 8 for men with morbid obesity and 1 in 7 for women.

“These findings raise questions concerning whether current obesity treatment frameworks, grounded in weight management programs accessed through primary care, may be expected to achieve clinically relevant and sustained reductions in BMI for the vast majority of obese patients and whether they could be expected to do so in the future,” the authors suggest.

Rate of newborn circumcision may be linked to type of health insurance New research from the American Journal of Public Health finds the recent decrease in the incidence of male newborn circumcision may be linked to state Medicaid plans no longer covering the procedure and shifts in coverage of birth hospitalizations from private insurance to Medicaid.

Researchers reviewed male newborn birth hospitalizations from a sample of hospital discharge data known as the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project, to which 45 states contribute data. Trends in circumcision incidence were assessed between 2000 and 2010, with particular interest in whether the birth hospitalization was covered by private insurance or Medicaid.

Results from the study indicate that between 2000 and 2010, circumcision incidence decreased from 61.3 percent to 56.9 percent. Overall, births covered by Medicaid have a lower incidence of circumcision compared to births under private insurance. A notable decrease was observed in the South among births covered by Medicaid. Of note, during this time period many states’ Medicaid no longer covered circumcision. In addition there was a shift, with an increase in the proportion of birth hospitalizations covered by Medicaid.

“Efforts should be made to reduce insurance barriers to newborn circumcision for families that desire the procedure,” the authors conclude.

Health care providers hold implicit and explicit biases based on sexual orientationNew research from the American Journal of Public Health finds that heterosexual health providers, similar to non-providers, reported moderate to strong implicit preferences for straight people over lesbian women and gay men.

Researchers used results from the Sexuality Implicit Association Test developed to assess presence of implicit bias towards either heterosexual, lesbian and gay individuals. The IAT captured demographic data and test results for more than 200,000 participants between May 2006 and December 2012. In addition, all test takers indicated their explicit preferences towards heterosexual, gay people by endorsing statements ranging from “I strongly prefer straight people to gay people” to “I strongly prefer gay people to straight people.” Using demographic information, the study also categorized each respondent as a medical doctor, nurse, mental health provider, other treatment provider or non-provider to assess attitudes specifically from health care providers.

Results indicated that heterosexual health providers expressed moderate to strong implicit preferences for heterosexual people over lesbian and gay people. In addition, lesbian and gay health providers expressed implicit and explicit preferences for lesbian and gay people over straight people. Bisexual providers were found to have mixed preferences, mental health providers held the weakest implicit bias for heterosexual people and nurses held the strongest implicit bias for heterosexual people.

“For health care organizations that aim to serve these populations, these data suggest an opportunity to examine methods likely to mitigate implicit biases, such as eliminating discretion from decision-making, use of clinical guidelines, awareness of personal bias as self-caution, organizational policies that promote objective decision-making, and inclusion of counter-stereotypical experiences in educational programs,” the authors conclude.

They further note, “education to reduce sexual prejudice is a growing area of intervention and future research should examine how providers’ implicit and explicit preferences toward sexual orientation affect delivery of care to members of sexual minority populations.”
