The Center for Disease Control and Prevention released a report that highlights the effect of clinical preventive services in an individual's lifetime.

The report was from a supplement by the Morbidity and Mortality Weekly Report, which showed that millions of U.S. infants, children and adolescents did not receive key clinical preventive services.

The report is from 2012 data, before or shortly after the Affordable Care Act (Obamacare) was implemented, and showed that there are large disparities by demographics, geography, and healthcare coverage and access in the use of these services, according to the CDC.

Services for breastfeeding, hearing loss, lead poisoning, vision, hypertension, dental, HPV vaccination, tobacco, chlamydia and reproductive health overall were analyzed.

The report appears to have been issued to champion the ACA, based on language in the introduction of the report.

"The Affordable Care Act (ACA) expands insurance coverage, consumer protections, and access to care for the U.S. population and places a greater emphasis on prevention. Through implementation of ACA, new opportunities exist to promote and improve use of these valuable and vital services," the CDC said in the report.

The key findings of the report include high percentages of individuals, of all ages, who have not had clinical advice or visits.

About 17 percent of pregnant women did not receive breastfeeding counseling in 2010, and about 50 percent of infants who failed their hearing screening were not tested for hearing loss.

About 67 percent of children aged 1-2 were not screened and reported for lead poisoning in 2010, and at least 22 percent of 5-year-olds never had their vision checked.

About 56 percent of children and adolescents had not visited a dentist in 2008, and much more than half of those did not receive dental sealants or topical fluoride applications.

The data highlights the lack of attention paid by parents both for themselves and their children in seeking clinical advice and attention to ensure a healthy upbringing and long life, NPR reported.
