Current Asthma Prevalence by Weight Status Among Adults: United States, 2001–2014

March 16, 2016

Asthma is a common chronic airway disorder characterized by periods of airflow obstruction known as asthma attacks. Symptom frequency can range from intermittent to constant, and attack severity can vary from mild to life threatening.

Several studies have shown that among adults, obesity is associated with an increased risk of asthma diagnosis, more frequent asthma-related health care use, and greater symptom or severity burden.

In a new NCHS report, current asthma prevalence is examined by weight status among U.S. adults aged 20 and over.

Findings:

  • In 2011–2014, current asthma prevalence was 8.8% among adults. It was higher among adults with obesity (11.1%) compared with adults in normal weight (7.1%) and overweight (7.8%) categories.
  • Women with obesity had higher current asthma prevalence (14.6%) than those in normal weight (7.9%) and overweight (9.1%) categories. Current asthma prevalence did not differ significantly by weight status for men.
  • Current asthma prevalence was highest among adults with obesity for all race and Hispanic origin groups and age groups.
  • Overall current asthma prevalence among adults increased from 2001–2002 (7.1%) to 2013–2014 (9.2%). By weight status, prevalence increased among overweight adults but not among adults in the obese or normal weight categories.

 


Asthma Awareness Month

May 7, 2014

Illustration of person using asthma inhaler.May is Asthma Awareness Month and it’s important to recognize one of the most common lifelong chronic diseases.

Asthma is a common chronic airway disorder characterized by periods of reversible airflow obstruction known as asthma attacks.  Airflow is obstructed by inflammation and airway hyperreactivity (contraction of the small muscles surrounding the airways) in reaction to certain exposures.  Exposures include exercise, infection, allergens (e.g., pollen), occupational exposures (e.g., chemicals), and airborne irritants (e.g., environmental tobacco smoke).

Symptoms may include wheezing, coughing, shortness of breath, and chest tightness. It is not clear how to prevent asthma from developing and there is no cure. Yet the means to control and prevent exacerbations in persons who have asthma are well established in evidence-based clinical guidelines.

3,404 people died of asthma in 2010, according to the most recent national data.

In 2010, 439,000 people were discharged from the hospital with asthma as first-listed diagnosis and the average length of stay was over 3 days.

Asthma prevalence (the percentage of people who have ever been diagnosed with asthma and still have asthma) increased from 7.3% in 2001 to 8.4% in 2010.  Also, an estimated 25.7 million people had asthma: 18.7 million adults and 7 million children and adolescents.

Children and adolescents had higher asthma prevalence (9.5%) than adults (7.7%) for the period 2008–2010. Females had higher asthma prevalence than males (9.2% compared with 7%).

However, data from the National Health Interview Survey show that asthma prevalence in the U.S. dropped sharply during the first nine months of 2013.

A brief look at asthma

November 5, 2008

Two weeks ago, NCHS released a report concerning the prevalence of food allergies in children. In this report, the authors reported that “children with food allergy are two to four times more likely to have other related conditions such as asthma and other allergies, compared with children without food allergies.” According to the report, about 3 million children have food allergies. However, statistics show that asthma affects almost 7 million children, and asthma rates more than doubled between the 1980s and 1990s. The cause of the condition, like food allergies, is still relatively uknown (Advance Data 381).

America’s Children: Key National Indicators of Well-Being

July 19, 2007

Last Friday we released the 10th anniversary edition of America’s Children, a product of the Federal Interagency Forum on Child and Family Statistics.

The Federal Interagency Forum on Child and Family Statistics (Forum) is a collection of 22 Federal government agencies involved in research and activities related to children and families. The Forum was founded in 1994 and formally established in April 1997 under Executive Order No. 13045. The mission of the Forum is to foster coordination and collaboration and to enhance and improve consistency in the collection and reporting of Federal data on children and families. The Forum also aims to improve the reporting and dissemination of information on the status of children and families.

Quite a bit of media interest was generated (here | here) on the subject of teen sexual behavior but there was much more to the report. The full report is available here and our overview of the data on health indicators which we contributed to is below the fold.

Asthma Prevalence

June 26, 2007

Asthma continues to be a concern among America’s Children. According to the National Centers for Health Statistics report The State of Childhood Asthma, United States, 1980–2005:

Millions of children in the United States are affected by asthma, a chronic respiratory disease characterized by attacks of difficulty breathing. An asthma attack is a distressing and potentially life-threatening experience. Scientific advances have greatly improved the understanding of the mechanisms that cause asthma attacks and have led to effective medical interventions to prevent morbidity and improve quality of life. Yet, the burden in prevalence, health care use, and mortality remains high. Asthma remains a significant public health problem in the United States.
