Adherence to National Guidelines on Cervical Screening: A Population-Based Evaluation from a Statewide Registry.

In 2012, national recommendations for cervical-cancer screening of women aged 30-64 years were quinquennial human papillomavirus and cytology co-testing or triennial cytology. Data from a state-wide surveillance program in New Mexico demonstrated 65.2% (95% confidence interval [95%CI]= 64.6%% to 65.7%) of women screened in 2019 had negative co-test within the last 3 years. Percentages of women screened in 2013, 2016, and 2019 with a prior negative co-test more than 5 and up to 7 years ago were 2.6% (95% CI = 2.2% to 2.9%), 2.1% (95% CI = 1.9% to 2.2%), and 6.5% (95% CI = 6.2% to 6.8%), respectively (2-sided P trend<.001). Percentages of women screened in 2013, 2016, and 2019 with a prior negative cytology more than 5 and up to 7 years ago were 3.8% (95% CI = 3.7% to 3.9%), 9.0% (95% CI = 8.7% to 9.3%), and 14.9% (95% CI = 14.4% to 15.4%), respectively (2-sided P trend<.001). Thus, in 2019, only 12.7% (95% CI = 12.4% to 13.1%) of the 30,215 women aged 30-64 years underwent co-testing and 27.7% (95% CI = 27.1% to 28.3%) of the 18,733 underwent cytology at the recommended interval. The observed under- and over-screening could result in increases in cervical-cancer incidence and harms and costs, respectively.

Population-Based Incidence Rates of Cervical Intraepithelial Neoplasia in the Human Papillomavirus Vaccine Era.

IMPORTANCE: A substantial effect of human papillomavirus (HPV) vaccines on reducing HPV-related cervical disease is essential before modifying clinical practice guidelines in partially vaccinated populations. OBJECTIVE: To determine the population-based cervical intraepithelial neoplasia (CIN) trends when adjusting for changes in cervical screening practices that overlapped with HPV vaccination implementation. DESIGN, SETTING, AND PARTICIPANTS: The New Mexico HPV Pap Registry, which captures population-based estimates of both cervical screening prevalence and CIN, was used to compute CIN trends from January 1, 2007, to December 31, 2014. Under New Mexico Administrative Code, the New Mexico HPV Pap Registry, a statewide public health surveillance program, receives mandatory reporting of all cervical screening (cytologic and HPV testing) and any cervical, vulvar, and vaginal histopathological findings for all women residing in New Mexico irrespective of outcome. MAIN OUTCOME MEASURES: Prespecified outcome measures included low-grade CIN (grade 1 [CIN1]) and high-grade CIN (grade 2 [CIN2] and grade 3 [CIN3]). RESULTS: From 2007 to 2014, a total of 13 520 CIN1, 4296 CIN2, and 2823 CIN3 lesions were diagnosed among female individuals 15 to 29 years old. After adjustment for changes in cervical screening across the period, reductions in the CIN incidence per 100 000 women screened were significant for all grades of CIN among female individuals 15 to 19 years old, dropping from 3468.3 to 1590.6 for CIN1 (annual percentage change [APC], -9.0; 95% CI, -12.0 to -5.8; P < .001), from 896.4 to 414.9 for CIN2 (APC, -10.5; 95% CI, -18.8 to -1.2; P = .03), and from 240.2 to 0 for CIN3 (APC, -41.3; 95% CI, -65.7 to 0.3; P = .05). Reductions in the CIN2 incidence were also significant for women 20 to 24 years old, dropping from 1027.7 to 627.1 (APC, -6.3; 95% CI, -10.9 to -1.4; P = .02). CONCLUSIONS AND RELEVANCE: Population-level decreases in CIN among cohorts partially vaccinated for HPV may be considered when clinical practice guidelines for cervical cancer screening are reassessed. Evidence is rapidly growing to suggest that further increases in raising the age to start screening are imminent, one step toward integrating screening and vaccination.

Sexual and drug use risk behaviors of long-haul truck drivers and their commercial sex contacts in New Mexico.

OBJECTIVES: Long-haul truck drivers and their commercial sex contacts (CCs) have been associated with the spread of sexually transmitted infections (STIs) in the developing world. However, there is a paucity of information about the STI risk behaviors of these populations in the U.S. We conducted a qualitative phase of a two-phase study to gather information about STI-related risk behaviors in drivers and their CCs in New Mexico. METHODS: Between July and September 2004, we conducted face-to-face unstructured and semistructured qualitative interviews at trucking venues, health department facilities, and a community-based organization to solicit information on sexual behavior and condom and illicit drug use. The interviews were audiotaped, transcribed, reviewed for quality control, and then coded and analyzed for emerging themes using NVivo software. RESULTS: Thirty-three long-haul truck drivers and 15 CCs completed the interview. The truck drivers were mostly male and non-Hispanic white with a mean age of 41 years. The majority of the CCs were female, the largest percentage was Hispanic, and the mean age was 36 years. Data suggested risky sexual behavior and drug use (i.e., inconsistent condom use, illicit drug use including intravenous drug use, and the exchange of sex for drugs) that could facilitate STI/human immunodeficiency virus (HIV) and hepatitis virus transmission. Results also showed a low knowledge about STIs and lack of access to general health care for both populations. CONCLUSIONS: Additional studies are needed to further assess risk and inform the development of prevention interventions and methods to provide STI/HIV and other medical services to these populations.

Risk assessment and screening for sexually transmitted infections, HIV, and hepatitis virus among long-distance truck drivers in New Mexico, 2004-2006.

OBJECTIVES: We examined sexually transmitted infection (STI), HIV, and hepatitis virus prevalence and risk behaviors among truck drivers. METHODS: We asked participants about their risk behaviors, and we screened them for STIs, HIV, and hepatitis infections. We used logistic regression to identify factors associated with outcomes. RESULTS: Of the 652 enrolled participants, 21% reported sex with sex workers or casual partners in the prior year. Driving solo (odds ratio [OR] = 15.04; 95% confidence interval [CI] = 1.92, 117.53; P = .01), history of injection drug use (IDU; OR = 2.69; 95% CI = 1.19, 6.12; P = .02), and history of an STI (OR = 2.47; 95% CI = 1.19, 5.09; P = .01) were independently associated with high-risk sexual behaviors. Fourteen percent of participants reported drug use in the previous year, and 11% reported having ever injected drugs. Participants tested positive as follows: 54 for HCV antibodies (8.5%), 66 for hepatitis B anticore (anti-HBc) antibodies (10.4%), 8 for chlamydia (1.3%), 1 for gonorrhea (0.2%), 1 for syphilis (0.2%), and 1 for HIV (0.2%). History of injecting drugs (OR = 26.91; 95% CI = 11.61, 62.39; P < .01) and history of anti-HBc antibodies (OR = 7.89; 95% CI = 3.16, 19.68; P < .01) were associated with HCV infection. CONCLUSIONS: Our results suggest a need for hepatitis C screening and STI risk-reduction interventions in this population.
