Complete Indicator Profile of Chlamydia Rates

Definition

Chlamydia cases reported in the state of New Mexico per 100,000 population.

Numerator

Number of cases of chlamydia reported to the state of New Mexico (and Centers for Disease Control) in New Mexico residents from all health care providers.

Denominator

Total Population

Data Interpretation Issues

Rates are partly a function of how much testing is done - the more you test, the more you find - which is why females have roughly three times the number of reported cases as males. Testing increased throughout the 1990s, and the number of new cases jumped in 2004 due to new nucleic acid amplitude testing technology which is much more sensitive than previous culture tests.

Why Is This Important?

Chlamydia is the most common bacterial sexually transmitted disease. Even though symptoms of chlamydia are usually mild or absent, serious complications that cause irreversible damage, including infertility, can occur "silently" before a woman ever recognizes a problem(1). It is the leading preventable cause of infertility, and screening and treatment are the best means of preventing it.

Other Objectives

Similar to HP2020 objectives STD-1: Reduce the proportion of adolescents and young adults with Chlamydia trachomatis infections and STD-2: Reduce Chlamydia rates among females aged 15 to 44 years.

How Are We Doing?

Overall, chlamydia rates have been increasing from 2005 (435.0 per 100,000 population) to 2012 (573.2 per 100,000 population). In 2012, chlamydia rates were highest in the American Indian/Alaska Native race/ethnicity category (1106.1 per 100,000), second highest in the Black/African American category, (691.2 per 100,000 population), and third highest in the Hispanic category (436.6 per 100,000). The lowest rates were found in the White category (190.1 per 100,000 population) and Asian/Pacific Islander category (122.2 per 100,000) respectively. By county, the highest Chlamydia rate for 2012 was found in McKinley county (1291.1 per 100,000), followed by Dona Ana County (698.5 per 100,000) and Bernalillo County (612.5 per 100,000). It is unknown whether this is an actual increase in rates or due to better testing and detection activities.

How Do We Compare With U.S.?

Chlamydia rates in New Mexico have consistently ranked higher than U.S. rates from year 2005 to 2011. In 2011, New Mexico had the 8th highest Chlamydia rate in the U.S. (U.S. data for 2012 not available as of this printing).

What Is Being Done?

Chlamydia testing is performed on females under age 26 at approximately 200 test sites including 54 public health offices and family planning and other provider agreement sites, in addition to routine treatment and surveillance activities.

Evidence-based Practices

Despite an A recommendation from the U.S Preventive Services Task Force to annually screen all sexually active females under age 25, data from health plans shows that fewer than 50% of that group actually gets screened each year. Chlamydia is the leading preventable cause of infertility, and screening and treatment are the best means of preventing it.

Risk Factors

Chlamydia can be transmitted during vaginal, anal, or oral sex. Chlamydia can also be passed from an infected mother to her baby during vaginal childbirth.

Any sexually active person can be infected with chlamydia. The greater the number of sex partners, the greater the risk of infection.
