Seasonal influenza vaccination coverage - United States, 2009-10 and 2010-11
McIntyre AF , Gonzalez-Feliciano AG , Bryan LN , Santibanez TA , Williams WW , Singleton JA . MMWR Suppl 2013 62 (3) 65-8 Infection with influenza viruses can cause severe morbidity and mortality among all age groups. Children, particularly those aged <5 years, have the highest incidence of infection during epidemic periods; however, the highest rates of influenza-associated hospitalizations and deaths are among the elderly (aged ≥65 years), children aged <2 years, and those of any age with underlying medical conditions. Each year, influenza-related complications are estimated to result in more than 226,000 hospitalizations. During 1976-2006, estimates of influenza-associated deaths in the United States ranged from approximately 3,000 to an estimated 49,000 persons. Annual vaccination is the most effective strategy for preventing influenza virus infection and its complications. |
Hypospadias and maternal intake of phytoestrogens
Carmichael SL , Cogswell ME , Ma C , Gonzalez-Feliciano A , Olney RS , Correa A , Shaw GM . Am J Epidemiol 2013 178 (3) 434-40 Experimental data indicate that gestational exposures to estrogenic compounds impact risk of hypospadias. We examined whether risk of hypospadias (i.e., a congenital malformation in which the opening of the penile urethra occurs on the ventral side of the penis) was associated with maternal intake of phytoestrogens, given their potential impact on estrogen metabolism. The analysis included data on mothers of 1,250 hypospadias cases and 3,118 controls who delivered their infants from 1997 to 2005 and participated in the National Birth Defects Prevention Study, a multistate, population-based, case-control study. After adjustment for several covariates, high intakes of daidzein, genistein, glycetin, secoisolariciresinol, total isoflavones, total lignans, and total phytoestrogens were associated with reduced risks; odds ratios comparing intakes ≥90th percentile with intakes between the 11th and 89th percentiles ranged from 0.6 to 0.8. For example, the odds ratio for total phytoestrogen intake was 0.7 (95% confidence interval: 0.5, 1.0). This study represents the first large-scale analysis of phytoestrogen intake and hypospadias. The observed associations merit investigation in additional populations before firm conclusions can be reached. |
Influenza A (H1N1) 2009 monovalent and seasonal influenza vaccination among adults 25 to 64 years of age with high-risk conditions-United States, 2010
Lu PJ , Gonzalez-Feliciano A , Ding H , Bryan LN , Yankey D , Monsell EA , Greby SM , Euler GL . Am J Infect Control 2013 41 (8) 702-9 BACKGROUND: Seasonal influenza vaccination has been routinely recommended for adults with high-risk conditions. The Advisory Committee on Immunization Practices recommended that persons 25 to 64 years of age with high-risk conditions be one of the initial target groups to receive H1N1 vaccination during the 2009-2010 season. METHODS: We used data from the 2009-2010 Behavioral Risk Factor Surveillance System survey. Vaccination levels of H1N1 and seasonal influenza vaccination among respondents 25 to 64 years with high-risk conditions were assessed. Multivariable logistic regression models were performed to identify factors independently associated with vaccination. RESULTS: Overall, 24.8% of adults 25 to 64 years of age were identified to have high-risk conditions. Among adults 25 to 64 years of age with high-risk conditions, H1N1 and seasonal vaccination coverage were 26.3% and 47.6%, respectively. Characteristics independently associated with an increased likelihood of H1N1 vaccination were as follows: higher age; Hispanic race/ethnicity; medical insurance; ability to see a doctor if needed; having a primary doctor; a routine checkup in the previous year; not being a current smoker; and having high-risk conditions other than asthma, diabetes, and heart disease. Characteristics independently associated with seasonal influenza vaccination were similar compared with factors associated with H1N1 vaccination. CONCLUSION: Immunization programs should work with provider organizations to review efforts made to reach adults with high-risk conditions during the recent pandemic and assess how and where they can increase vaccination coverage during future pandemics. |
Virus-specific differences in rates of disease during the 2010 dengue epidemic in Puerto Rico
Sharp TM , Hunsperger E , Santiago GA , Munoz-Jordan JL , Santiago LM , Rivera A , Rodriguez-Acosta RL , Gonzalez Feliciano L , Margolis HS , Tomashek KM . PLoS Negl Trop Dis 2013 7 (4) e2159 BACKGROUND: Dengue is a potentially fatal acute febrile illness (AFI) caused by four mosquito-transmitted dengue viruses (DENV-1-4) that are endemic in Puerto Rico. In January 2010, the number of suspected dengue cases reported to the passive dengue surveillance system exceeded the epidemic threshold and an epidemic was declared soon after. METHODOLOGY/PRINCIPAL FINDINGS: To characterize the epidemic, surveillance and laboratory diagnostic data were compiled. A suspected case was a dengue-like AFI in a person reported by a health care provider with or without a specimen submitted for diagnostic testing. Laboratory-positive cases had: (i) DENV nucleic acid detected by reverse transcriptase-polymerase chain reaction (RT-PCR) in an acute serum specimen; (ii) anti-DENV IgM antibody detected by ELISA in any serum specimen; or (iii) DENV antigen or nucleic acid detected in an autopsy-tissue specimen. In 2010, a total of 26,766 suspected dengue cases (7.2 per 1,000 residents) were identified, of which 46.6% were laboratory-positive. Of 7,426 RT-PCR-positive specimens, DENV-1 (69.0%) and DENV-4 (23.6%) were detected more frequently than DENV-2 (7.3%) and DENV-3 (<0.1%). Nearly half (47.1%) of all laboratory-positive cases were adults, 49.7% had dengue with warning signs, 11.1% had severe dengue, and 40 died. Approximately 21% of cases were primary DENV infections, and 1-4 year olds were the only age group for which primary infection was more common than secondary. Individuals infected with DENV-1 were 4.2 (95% confidence interval [CI]: 1.7-9.8) and 4.0 (95% CI: 2.4-6.5) times more likely to have primary infection than those infected with DENV-2 or -4, respectively. CONCLUSIONS/SIGNIFICANCE: This epidemic was long in duration and yielded the highest incidence of reported dengue cases and deaths since surveillance began in Puerto Rico in the late 1960's. This epidemic re-emphasizes the need for more effective primary prevention interventions to reduce the morbidity and mortality of dengue. |
Influenza vaccination coverage - United States, 2000-2010
Setse RW , Euler GL , Gonzalez-Feliciano AG , Bryan LN , Furlow C , Weinbaum CM , Singleton JA . MMWR Suppl 2011 60 (1) 38-41 Vaccines are among the greatest public health achievements of the 20th century (1). The majority of Healthy People 2010 (HP2010) objectives for early childhood vaccination coverage were met by the end of 2010 (2), and progress has been made toward eliminating disparities in vaccination coverage among children (3,4). Remarkable progress also has been made in improving coverage and reducing disparities in coverage for adolescent vaccinations recommended since 2005 (5). Although childhood vaccination programs in the United States have been successful, adolescent programs remain relatively new and adult vaccination programs, although well established, have not achieved acceptable levels of success. Among adults, substantial disparities in vaccination coverage have persisted (6--10). A particular challenge for prevention of influenza is the need for annual vaccination. During 1989--1999, national influenza vaccination coverage among persons aged ≥65 years increased each year for all racial/ethnic groups; however, the rate of increase slowed during 1997--2001, and vaccination coverage among non-Hispanic blacks and Hispanics remained lower compared with non-Hispanic whites throughout the entire period (1989--2001) (11). | | To examine racial/ethnic disparities in influenza vaccination coverage among all persons aged ≥6 months for the 2009--10 influenza season as well as trends in racial/ethnic disparities in influenza vaccination coverage for the 2000--01 through 2009--10 influenza seasons among adults aged ≥65 years, CDC analyzed data from the 2002--2010 Behavioral Risk Factor Surveillance System (BRFSS) questionnaire and the National 2009 H1N1 Flu Survey (NHFS). Racial/ethnic disparities were focused on because these disparities in vaccination coverage have been documented (11--13) more extensively compared with other disparity domains (e.g., sex, income, education, and disability status). State-level estimates have been published previously (14,15) and are not included in this report. |
Estimated dietary phytoestrogen intake and major food sources among women during the year before pregnancy
Carmichael SL , Gonzalez-Feliciano AG , Ma C , Shaw GM , Cogswell ME . Nutr J 2011 10 105 BACKGROUND: Phytoestrogens may be associated with a variety of different health outcomes, including outcomes related to reproductive health. Recently published data on phytoestrogen content of a wide range of foods provide an opportunity to improve estimation of dietary phytoestrogen intake. METHODS: Using the recently published data, we estimated intake among a representative sample of 6,584 women of reproductive age from a multi-site, population-based case-control study, the National Birth Defects Prevention Study (NBDPS). The NBDPS uses a shortened version of the Willett food frequency questionnaire to estimate dietary intake during the year before pregnancy. We estimated intake among NBDPS control mothers. RESULTS: Lignans contributed 65% of total phytoestrogen intake; isoflavones, 29%; and coumestrol, 5%. Top contributors to total phytoestrogen intake were vegetables (31%) and fruit (29%); for isoflavones, dairy (33%) and fruit (21%); for lignans, vegetables (40%) and fruit (29%); and for coumestans, fruit (55%) and dairy (18%). Hispanic women had higher phytoestrogen intake than non-Hispanic white or black women. Associations with maternal age and folic acid-containing supplements were more modest but indicated that older mothers and mothers taking supplements had higher intake. CONCLUSIONS: The advantage of the approach used for the current analysis lies in its utilization of phytoestrogen values derived from a single laboratory that used state-of-the-art measurement techniques. The database we developed can be applied directly to other studies using food frequency questionnaires, especially the Willett questionnaire. The database, combined with consistent dietary intake assessment, provides an opportunity to improve our ability to understand potential associations of phytoestrogen intake with health outcomes. |
