Influenza Vaccination Coverage Among Health Care Personnel - United States, 2015-16 Influenza Season.

The Advisory Committee on Immunization Practices recommends annual influenza vaccination for all health care personnel to reduce influenza-related morbidity and mortality among both health care personnel and their patients (1-4). To estimate influenza vaccination coverage among U.S. health care personnel for the 2015-16 influenza season, CDC conducted an opt-in Internet panel survey of 2,258 health care personnel during March 28-April 14, 2016. Overall, 79.0% of survey participants reported receiving an influenza vaccination during the 2015-16 season, similar to the 77.3% coverage reported for the 2014-15 season (5). Coverage in long-term care settings increased by 5.3 percentage points compared with the previous season. Vaccination coverage continued to be higher among health care personnel working in hospitals (91.2%) and lower among health care personnel working in ambulatory (79.8%) and long-term care settings (69.2%). Coverage continued to be highest among physicians (95.6%) and lowest among assistants and aides (64.1%), and highest overall among health care personnel who were required by their employer to be vaccinated (96.5%). Among health care personnel working in settings where vaccination was neither required, promoted, nor offered onsite, vaccination coverage continued to be low (44.9%). An increased percentage of health care personnel reporting a vaccination requirement or onsite vaccination availability compared with earlier influenza seasons might have contributed to the overall increase in vaccination coverage during the past 6 influenza seasons.

Influenza Vaccination Coverage Among Health Care Personnel--United States, 2014-15 Influenza Season.

The Advisory Committee on Immunization Practices recommends annual influenza vaccination for all health care personnel (HCP) to reduce influenza-related morbidity and mortality among both HCP and their patients and to decrease absenteeism among HCP. To estimate influenza vaccination coverage among U.S. HCP for the 2014­15 influenza season, CDC conducted an opt-in Internet panel survey of 1,914 HCP during March 31­April 15, 2015. Overall, 77.3% of HCP survey participants reported receiving an influenza vaccination during the 2014­15 season, similar to the 75.2% coverage among HCP reported for the 2013­14 season. Vaccination coverage was highest among HCP working in hospitals (90.4%) and lowest among HCP working in long-term care (LTC) settings (63.9%). By occupation, coverage was highest among pharmacists (95.3%) and lowest among assistants and aides (64.4%). Influenza vaccination coverage was highest among HCP who were required by their employer to be vaccinated (96.0%). Among HCP without an employer requirement for vaccination, coverage was higher for HCP working in settings where vaccination was offered on-site at no cost for 1 day (73.6%) or multiple days (83.9%) and lowest among HCP working in settings where vaccine was neither required, promoted, nor offered on-site (44.0%). Comprehensive vaccination strategies that include making vaccine available at no cost at the workplace along with active promotion of vaccination might help increase vaccination coverage among HCP and reduce the risk for influenza to HCP and their patients.

Selected findings from the cross-site evaluation of the Federal Healthy Start Program.

Initiated in 1991, the Federal Healthy Start Program includes 105 community-based projects in 39 states, the District of Columbia and Puerto Rico. Healthy Start projects work collaboratively with stakeholders to ensure participants' continuity of care during pregnancy through 2 years postpartum. This evaluation of Healthy Start projects examined relationships between implementation of nine core service and system program components and improvements in birth and project outcomes. Program components and outcomes were examined using data from a 2010 Healthy Start project director (PD) survey (N = 104 projects) and 2009 performance measure data from the Maternal and Child Health Bureau Discretionary Grant Information System (N = 98 projects). We explored bivariate relationships between the nine core program components and (a) intermediate and long-term project outcomes and (b) birth outcomes. We assessed independent associations of implementation of all core program components with birth outcomes, adjusting for project characteristics and activities. In 2010, 57 projects implemented all nine core program components: 104 implemented all five core service components and 69 implemented all four core systems components. Implementation of all core program components was significantly associated with several PD-reported intermediate and long-term project outcomes, but was not associated with singleton low birth weight or infant mortality among participants' infants. This evaluation revealed a mixed set of relationships between Healthy Start projects' implementation of the core program components and achievement of project outcomes. Although the findings demonstrated a positive impact of Healthy Start projects on birth outcomes, only a few associations were statistically significant.

Influenza vaccination coverage among health care personnel--United States, 2013-14 influenza season.

The Advisory Committee on Immunization Practices recommends that all health care personnel (HCP) be vaccinated annually against influenza. Vaccination of HCP can reduce influenza-related morbidity and mortality among both HCP and their patients. To estimate influenza vaccination coverage among HCP during the 2013-14 season, CDC analyzed results of an opt-in Internet panel survey of 1,882 HCP conducted during April 1-16, 2014. Overall, 75.2% of participating HCP reported receiving an influenza vaccination during the 2013-14 season, similar to the 72.0% coverage among participating HCP reported in the 2012-13 season. Coverage was highest among HCP working in hospitals (89.6%) and lowest among HCP working in long-term care (LTC) settings (63.0%). By occupation, coverage was highest among physicians (92.2%), nurses (90.5%), nurse practitioners and physician assistants (89.6%), pharmacists (85.7%), and "other clinical personnel" (87.4%) compared with assistants and aides (57.7%) and nonclinical personnel (e.g., administrators, clerical support workers, janitors, and food service workers) (68.6%). HCP working in settings where vaccination was required had higher coverage (97.8%) compared with HCP working in settings where influenza vaccination was not required but promoted (72.4%) or settings where there was no requirement or promotion of vaccination (47.9%). Among HCP without an employer requirement for vaccination, coverage was higher for HCP working in settings where vaccination was offered on-site at no cost for 1 day (61.6%) or multiple days (80.4%) compared with HCP working in settings not offering free on-site vaccination (49.0%). Comprehensive vaccination strategies that include making vaccine available at no cost at the workplace along with active promotion of vaccination might be needed to increase vaccination coverage among HCP and minimize the risk for influenza to HCP and their patients.

Correlates of pre-pregnancy physical inactivity: results from the pregnancy risk assessment monitoring system.

OBJECTIVES: Evaluate the prevalence of physical inactivity (no physical activity or exercise for 30 min or more at least one day per week) in the 3 months prior to pregnancy in a population-based sample of women and identify individual socio-demographic, personal, health, and behavioral factors predictive of pre-pregnancy physical inactivity. METHODS: In this cross-sectional study, we used data from the Centers for Disease Control and Prevention's Pregnancy Risk Assessment Monitoring System to assess the prevalence of self-reported pre-pregnancy physical activity among 4,069 women who delivered a live birth in 2004 in Maine, North Carolina, or Washington State. We developed a predictive model by using a backward selection approach to building logistic regression models to identify independent predictors of physical inactivity in the 3 months prior to pregnancy among those women who did not meet national recommendations for physical activity (activity more than 5 days per week). RESULTS: Overall, the prevalence of pre-pregnancy physical inactivity was 39.2%. Predictors of physical inactivity prior to pregnancy included higher or lower than normal pre-pregnancy body mass index, lower maternal education level, and a history of previous live births. Women with 12 years of education were particularly likely to be inactive prior to pregnancy (prevalence odds ratio 1.81, 95% confidence interval 1.42, 2.32; compared to women with more than 12 years of education). CONCLUSIONS: Physical inactivity is common among women prior to pregnancy. Information on factors predictive of physical inactivity can be used in the development of clinical activities and public health interventions that aim to reduce the level of physical inactivity among women of reproductive age.

Is distance to provider a barrier to care for medicaid patients with breast, colorectal, or lung cancer?

PURPOSE: Distance to provider might be an important barrier to timely diagnosis and treatment for cancer patients who qualify for Medicaid coverage. Whether driving time or driving distance is a better indicator of travel burden is also of interest. METHODS: Driving distances and times from patient residence to primary care provider were calculated for 3,917 breast, colorectal (CRC) and lung cancer Medicaid patients in Washington State from 1997 to 2003 using MapQuest.com. We fitted regression models of stage at diagnosis and time-to-treatment (number of days between diagnosis and surgery) to test the hypothesis that travel burden is associated with timely diagnosis and treatment of cancer. FINDINGS: Later stage at diagnosis for breast cancer Medicaid patients is associated with travel burden (OR = 1.488 per 100 driving miles, P= .037 and OR = 1.270 per driving hour, P= .016). Time-to-treatment after diagnosis of CRC is also associated with travel burden (14.57 days per 100 driving miles, P= .002 and 5.86 days per driving hour, P= .018). CONCLUSIONS: Although travel burden is associated with timely diagnosis and treatment for some types of cancer, we did not find evidence that driving time was, in general, better at predicting timeliness of cancer diagnosis and treatment than driving distance. More intensive efforts at early detection of breast cancer and early treatment of CRC for Medicaid patients who live in remote areas may be needed.

Prenatal fatty acid status and child adiposity at age 3 y: results from a US pregnancy cohort.

BACKGROUND: Exposure to polyunsaturated fatty acids (PUFAs) in early life may influence adiposity development. OBJECTIVE: We examined the extent to which prenatal n-3 (omega-3) and n-6 (omega-6) PUFA concentrations were associated with childhood adiposity. DESIGN: In mother-child pairs in the Project Viva cohort, we assessed midpregnancy fatty acid intakes (n = 1120), maternal plasma PUFA concentrations (n = 227), and umbilical cord plasma PUFA concentrations (n = 302). We performed multivariable regression analyses to examine independent associations of n-3 PUFAs, including docosahexaenoic and eicosapentaenoic acids (DHA + EPA), n-6 PUFAs, and the ratio of n-6:n-3 PUFAs, with child adiposity at age 3 y measured by the sum of subscapular and triceps skinfold thicknesses (SS + TR) and risk of obesity (body mass index ≥95th percentile for age and sex). RESULTS: Mean (±SD) DHA + EPA intake was 0.15 ± 0.14 g DHA + EPA/d, maternal plasma concentration was 1.9 ± 0.6%, and umbilical plasma concentration was 4.6 ± 1.2%. In children, SS + TR was 16.7 ± 4.3 mm, and 9.4% of children were obese. In the adjusted analysis, there was an association between each SD increase in DHA + EPA and lower child SS + TR [-0.31 mm (95% CI: -0.58, -0.04 mm) for maternal diet and -0.91 mm (95% CI: -1.63, -0.20 mm) for cord plasma] and lower odds of obesity [odds ratio (95% CI): 0.68 (0.50, 0.92) for maternal diet and 0.09 (0.02, 0.52) for cord plasma]. Maternal plasma DHA + EPA concentration was not significantly associated with child adiposity. A higher ratio of cord plasma n-6:n-3 PUFAs was associated with higher SS + TR and odds of obesity. CONCLUSION: An enhanced maternal-fetal n-3 PUFA status was associated with lower childhood adiposity.

Trends in birth weight and gestational length among singleton term births in the United States: 1990-2005.

OBJECTIVE: To estimate changes over time in birth weight for gestational age and in gestational length among term singleton neonates born from 1990 to 2005. METHODS: We used data from the U.S. National Center for Health Statistics for 36,827,828 singleton neonates born at 37-41 weeks of gestation, 1990-2005. We examined trends in birth weight, birth weight for gestational age, large and small for gestational age, and gestational length in the overall population and in a low-risk subgroup defined by maternal age, race or ethnicity, education, marital status, smoking, gestational weight gain, delivery route, and obstetric care characteristics. RESULTS: In 2005, compared with 1990, we observed decreases in birth weight (-52 g in the overall population, -79 g in a homogenous low-risk subgroup) and large for gestational age birth (-1.4% overall, -2.2% in the homogenous subgroup) that were steeper after 1999 and persisted in regression analyses adjusted for maternal and neonate characteristics, gestational length, cesarean delivery, and induction of labor. Decreases in mean gestational length (-0.34 weeks overall) were similar regardless of route of delivery or induction of labor. CONCLUSION: Recent decreases in fetal growth among U.S., term, singleton neonates were not explained by trends in maternal and neonatal characteristics, changes in obstetric practices, or concurrent decreases in gestational length.
