Associations of geographic-based socioeconomic factors and HPV vaccination among male and female children in five US states

BACKGROUND

We assessed whether five geographic-based socioeconomic factors (medically underserved area (MUA); healthcare provider shortage area (HPSA); persistent poverty; persistent child poverty; and social vulnerability index (SVI)) were associated with the odds of HPV vaccination initiation, series completion, and parental vaccine hesitancy, and whether the observed relationships varied by gender of the child.

METHODS

An online panel service, administered through Qualtrics®, was used to recruit parents of adolescents 9-17 years of age to complete a one-time survey in 2021. Coverage of the panel included five US states: Arkansas, Mississippi, Missouri, Tennessee, and Southern Illinois. Generalized estimating equation (GEE) models were used to assess population-level associations between five geographic-based socioeconomic factors (MUA; HPSA; persistent poverty; persistent child poverty; and SVI) and three HPV vaccination outcomes (initiation, series completion, and hesitancy). All GEE models were adjusted for age of child and clustering at the state level.

RESULTS

Analyses were conducted using responses from 926 parents about their oldest child in the target age range (9-17 years). The analytic sample consisted of 471 male children and 438 female children across the five states. In adjusted GEE models, persistent child poverty and HPSA were negatively associated with HPV vaccination initiation and series completion among female children, respectively. Among male children, high social vulnerability was negatively associated with HPV vaccine series completion. Additionally, persistent poverty and high social vulnerability were negatively associated with HPV vaccine hesitancy in male children.

CONCLUSIONS

The results of this cross-sectional study suggest that geographic-based socioeconomic factors, particularly, HPSA, persistent poverty, and SVI, should be considered when implementing efforts to increase HPV vaccine coverage for adolescents. The approaches to targeting these geographic factors should also be evaluated in future studies to determine if they need to be tailored for male and female children.

Influences of sociodemographic characteristics and parental HPV vaccination hesitancy on HPV vaccination coverage in five US states

BACKGROUND

In the United States (US), half of new human papillomavirus (HPV) infections occur among young people aged 15-24 years. Despite the effectiveness of HPV vaccination in protecting against HPV-associated cancers, its coverage among adolescents remains suboptimal. This study examined the association of sociodemographic characteristics and HPV vaccination hesitancy with HPV vaccination coverage in five US states with disproportionately low adolescent coverage rates compared to the national average.

METHODS

Responses to an online Qualtrics survey from 926 parents of children aged 9-17 years in Arkansas, Mississippi, Missouri, Tennessee, and Southern Illinois in July 2021 were analyzed using multivariate logistic regression to estimate the association of sociodemographic characteristics and HPV vaccination hesitancy with HPV vaccination coverage.

RESULTS

Of the parents, 78 % were female, 76 % were non-Hispanic White, 61.9 % lived in rural areas, 22 % were classified as HPV vaccine hesitant, and 42 % had vaccinated their oldest child between the ages of 9-17 years against HPV. Children of vaccine hesitant parents were less likely to have received any doses of the HPV vaccine than children of non-vaccine hesitant parents (AOR: 0.17, 95 % CI:0.11-0.27). Male children were less likely to have initiated the HPV vaccine series than female children (AOR: 0.70, 95 % CI:0.50-0.97). Older children (13-17 vs 9-12 years), receiving the meningococcal conjugate or most recent seasonal influenza vaccine were all associated with higher likelihoods of receiving any doses of the HPV vaccine (AOR: 6.01, 95 % CI:3.98-9.08; AOR: 2.24, 95 % CI:1.27-3.95; AOR: 2.41, 95 % CI:1.73-3.36, respectively).

CONCLUSIONS

Adolescent HPV vaccination coverage remains low in our targeted states. Children's age, sex, and parental vaccine hesitancy were significantly associated with likelihood of HPV vaccination. These findings offer the opportunity for targeted interventions among parents in regions with low vaccine uptake and underscore the importance of developing and implementing strategies to address parental HPV vaccination hesitancy to improve uptake in the US.

Central versus Low-Lying Umbilical Venous Catheters: A Multicenter Study of Practices and Complications

OBJECTIVES

Conventional neonatology practice is to place umbilical venous catheters (UVCs) in central position and to limit the use of low-lying catheters. Our objectives were to describe the practices and complications associated with UVCs and to evaluate the type of infusates used with either UVC position.

STUDY DESIGN

A retrospective chart review was performed at four neonatal intensive care units to identify neonates who underwent UVC placement over a 2-year period. Infant demographics, UVC position, catheter days, fluid and medication characteristics, and specific complications were extracted.

RESULTS

A total of 2,011 neonates who underwent UVC placement were identified during the 2-year period. Of these, 641 UVCs (31.9%) were identified in the low-lying position. Centrally positioned UVCs were associated with lower gestational age and were left in situ for a longer duration than low-lying UVCs. Infusions of hyperosmolar solutions and vasopressors were significantly higher in central UVCs, though they were used in a significant number of low-lying UVCs. Complications, while not statistically different, were three times higher in low-lying UVCs.

CONCLUSION

Despite conventional teaching, low-lying UVCs were used in nearly one-third of infants in this cohort. Parenteral nutrition, antibiotics, and vasopressors were infused through central and low-lying UVCs. There was no statistically significant difference in complication rates between UVC positions.
