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

Response: The estimates in this study provide a more robust indicator of the economic impact falls have on the U.S. economy.  Previous studies focused on Medicare spending. This study includes Medicare, Medicaid and out-of-pocket spending.

MedicalResearch.com: What are the main findings? 

Response: Our study found that older adult (65 years and over) falls impose a large economic burden on the U.S. healthcare system. In 2015, with a total medical cost $50 billion for non-fatal and fatal falls.  About three-quarters of the total cost was paid by government-funded programs.  Medicare paid nearly $29 billion for non-fatal falls, Medicaid $8.7 billion, and $12 billion was paid for by Private/Out-of-pocket expenses.  For fatal falls, $754 million was spent in 2015.

Sonia Singh, PhD, Epidemiologist
Division of HIV/AIDS Prevention
CDC 

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

Response: HIV infection is a persistent health concern in the United States, particularly for people at high risk of infection such as gay and bisexual men. We used data from the National HIV Surveillance System to estimate HIV incidence and prevalence and the percentage of undiagnosed HIV infections overall and among gay and bisexual men.

Estimated HIV incidence declined nearly 15% overall in the U.S. from an estimated 45,200 infections in 2008 to 38,500 in 2015. Estimated HIV incidence declined for both males (9%) and females (33%) over this period. Estimated HIV incidence declined 32% among heterosexuals, 42% among people who inject drugs and 20% among gay and bisexual men who also inject drugs. Estimated HIV incidence remained relatively stable among gay and bisexual men; however, it increased over 25% among Latino gay and bisexual men, almost 45% among gay and bisexual men ages 25 to 34 and 30% among gay and bisexual men ages 55 and older.

The percentage of undiagnosed HIV infections decreased nearly 20%, from 18.1% in 2008 to 14.5% in 2015. The percentage of undiagnosed HIV infections among gay and bisexual men declined 21.6%, from 21.3% in 2008 to 16.7% in 2015. In 2015, the percentage of undiagnosed HIV infections was highest among gay and bisexual males ages 13-24 (52.2%) compared to other age groups and higher among Latino (20.1%) and African American (19.6%) gay and bisexual men, as well as Asian gay and bisexual men (20.5%), compared to white gay and bisexual men (11.9%).

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

Response: As noted in a previous study, antibiotics are prescribed more for sinus infections than any other illness in the United States. We found that almost 70% of antibiotic prescriptions were for 10 days or longer, whereas 5-7 days is recommended for most patients when antibiotics are needed. In addition, more than 20% of antibiotic prescriptions for sinus infections were for 5 days of azithromycin, even though guidelines recommend against prescribing azithromycin for sinus infections.

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

Response: In this analysis we examined recent trends in the prevalence of obesity and severe obesity among both youth and adults, by sex and age group.

Among adults, obesity and severe obesity prevalence has increased over the last 10 years.  Obesity prevalence increased from 33.7% in 2007-2008 to 39.6% or almost 40% in 2015-2016, and severe obesity increased from 5.7% in 2007-2008 to 7.7% in 2015-2016.  We see this same pattern of increasing prevalence of obesity and severe obesity in both men and women, and in different age groups.

On the other hand, among youth, we saw no increasing or decreasing trends in obesity or severe obesity prevalence over the 10 year period.  And this was true for both boys and girls and for different age groups.

Measured height and weight is the gold standard for generating accurate estimates of obesity prevalence.  The National Health and Nutrition Examination Survey is unique in that it combines both interviews in the home and physical examinations in mobile examination centers, and it is the only national survey where people’s height and weight are physically measured.  This is why NHANES is such an important source of data for understanding trends in obesity in youth and adults.

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

Response: Sunburn at any age increases a person’s chances of developing skin cancer in the future. Using a combination of strategies including staying in the shade, wearing clothing that covers the arms and legs, wearing a hat with a wide brim, and wearing sunscreen (SPF 15+) on exposed skin can protect skin from sun damage and reduce risk of sunburn.

This study used national data to examine how often US adults used these sun protection strategies when outdoors in the sun for an hour or longer and how many US adults got sunburned in 2015.

Among adult women, staying in the shade and using sunscreen were the most common sun protection methods. About 40% of women regularly used these strategies. Women were less likely to wear a wide-brimmed hat (14%) or wear clothing covering their arms (11%) and legs (23%).

Among adult men, wearing pants or other clothing covering their legs and staying in the shade were the most common sun protection methods. Just over 30% of men regularly used these strategies. Men were less likely to use sunscreen (22%), wear a wide-brimmed hat (14%) or wear a shirt with long sleeves (13%).

About one-third of US adults got sunburned in 2015. Sunburn was even more common among certain groups. For example, about half of individuals with sun-sensitive skin and about half of adults aged 18-29 got sunburned.

Certain behaviors and health conditions were related to sunburn. For example, adults who used sunless tanning products to darken their skin, binge drank, engaged in aerobic activity, or were overweight or obese were more likely to get sunburned compared to other adults. Adults who regularly stayed in the shade when outdoors or avoided long periods of time in the sun were slightly less likely to get sunburned compared to other adults.

Adults who regularly used sunscreen were slightly more likely to get sunburned. Continue reading →

Steady Increase in Melanoma In Older Adults

MedicalResearch.com Interview with:
Dawn Holman, MPH
Behavioral Scientist Division of Cancer Prevention and Control
CDC

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

Response: Melanoma is the third most common type of skin cancer and the most deadly. Each year in the United States, over 70,000 people are diagnosed with melanoma, and more than 9,000 die from the disease. Melanoma is often caused by overexposure to ultraviolet (UV) rays from the sun or artificial sources like tanning beds.

Previous reports have shown a steady increase in melanoma incidence rates over time, specifically among non-Hispanic whites. The purpose of this study was to determine if this trend differs across age groups.

This image depicts the gross appearance of a cutaneous pigmented lesion, which had been diagnosed as superficial spreading malignant melanoma (SSMM). Note the roughened edges of this mole, its heterogeneous, mottled, multicolored appearance, as well as its multi-textural composition, which are all characteristics that should evoke suspicions about its classification.
SSMM makes up 60 – 70% of clinical subtypes of melanoma, can appear at any site on the body, displays a radial growth pattern, and histopathologically, is found to reveal a more pagetoid, i.e., melanocytes spreading upward into epidermal layer, and less elastotic cytoarchitecture. Solar elastosis is characterized by a degeneration of the skin’s elastic and collagen fibers, giving it a sagging, wrinkled appearance.
SSMM:
– diagnosed most frequently between the ages of 30-50 years
– Most common on trunk in men and legs in women
– Brown-black macule that becomes a patch, and eventually takes on the appearance of a nodule
– 1/3rd arise from pre-existing nevus
– Regression common

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

Response: Insufficient sleep among children and adolescents is associated with an increased risk for obesity, diabetes, injuries, poor mental health, and attention and behavior problems.

In previous reports, CDC had found that, nationwide, approximately two thirds of U.S. high school students report sleeping <8 hours per night on school nights. CDC conducted this study to provide state-level estimates of short sleep duration on school nights among middle school and high school students using age-specific recommendations from the American Academy of Sleep Medicine (AASM). AASM has recommended that children aged 6–12 years should regularly sleep 9–12 hours per 24 hours and teenagers aged 13–18 years should sleep 8–10 hours per 24 hours for optimal health.

NIOSH

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

Response: Research has linked repeated exposure to occupational ergonomic hazards, such as frequent exertion and frequent standing, to injuries and musculoskeletal disorders (MSDs) among workers.

To determine the industry and occupation groups that have the highest prevalence rates of frequent exertion at work and frequent standing at work, NIOSH researchers analyzed 2015 National Health Interview Survey data. The results showed large differences among the groups with the agriculture, forestry, fishing, and hunting industry group having the highest prevalence of frequent exertion and standing at work (70.9%) and the construction and extraction occupation group having the highest prevalence of frequent exertion and standing at work (76.9%). These differences indicate a need for targeted interventions to reduce workplace exposure.

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

Response: Children with severe obesity face significant health and social challenges. Children with obesity and severe obesity are at higher risk for having other chronic health conditions and diseases, such as asthma, sleep apnea, bone and joint problems, and type 2 diabetes. They also have more risk factors for heart disease like high blood pressure, impaired glucose tolerance, and high cholesterol than their normal weight peers.

These lifelong health risks associated with severe obesity during early childhood indicate the importance of preventing and identifying severe obesity. Childhood obesity disproportionately affects children living in low-income families. However, no recent trends on severe obesity in this population have been reported.
