Generation status as a determinant of influenza vaccination among Mexican-identified adults in California, 2011-12.

ABSTRACT: First generation Latinos often have better health behaviors and outcomes than second and third generation Latinos. This study examined the correlates of seasonal influenza vaccinations among Mexican-identified (Mexican) adults, who make up the largest Latino subgroup in California. A sample of Mexican adults (N = 7493) from the 2011-12 California Interview Health Survey was used to compare the odds of first, second, and third generation Mexicans receiving influenza vaccinations in the past year. We performed a logistic regression taking into account socio-demographic characteristics, health status, and access to care. We repeated the analysis after stratifying for nativity, and then age. Being a second (odds ratio (OR) = 0.74, confidence interval (CI): 0.59, 0.92) and third generation or higher (OR = 0.66, CI: 0.51, 0.86) Mexican was associated with lower odds of getting an influenza vaccination compared to first generation Mexicans. Having a chronic disease, and access to care was associated with higher odds of vaccination, while lower age was associated with lower odds of vaccination among both US-, and foreign-born Mexicans. Given that the majority of Mexicans in California are US-born, the fact that being second- and third-generation Mexicans was associated with lower influenza vaccination rates is of significant concern.

Project description:BackgroundThere are few estimates of vaccination-averted influenza-associated illnesses in China.MethodsWe used a mathematical model and Monte Carlo algorithm to estimate numbers and 95% confidence intervals (CI) of influenza-associated outcomes (hospitalization, illness, and medically-attended (MA) illness) averted by vaccination among children aged 6-59 months in Suzhou from October 2011-September 2016. Influenza illnesses included non-hospitalized MA influenza illnesses and non-MA influenza illnesses. The numbers of influenza-associated outcomes averted by vaccination were the difference between the expected burden if there were no vaccination given and the observed burden with vaccination. The model incorporated the disease burden estimated based on surveillance data from Suzhou University Affiliated Children's Hospital (SCH) and data from health utilization surveys conducted in the catchment area of SCH, age-specific estimates of influenza vaccination coverage in Suzhou from the Expanded Program on Immunization database, and influenza vaccine effectiveness estimates from previous publications. Averted influenza estimations were presented as absolute numbers and in terms of the prevented fraction (PF). A hypothetical scenario with 50% coverage (but identical vaccine effectiveness) over the study period was also modeled.ResultsIn ~250,000 children, influenza vaccination prevented an estimated 731 (CI: 549-960) influenza hospitalizations (PF: 6.2% of expected, CI: 5.8-6.6%) and 10,024 (7593-12,937) influenza illnesses (PF: 6.5%, 6.4-6.7%), of which 8342 (6338-10,768) were MA (PF: 6.6%, 6.4-6.7%) from 2011 to 2016. The PFs declined each year along with decreasing influenza vaccination coverage. If 50% of the study population had been vaccinated over time, the estimated numbers of averted cases during the study period would have been 4059 (3120-5762) influenza hospitalizations (PF: 27.2%, 26.4-27.9%) and 56,215 (42,925-78,849) influenza illnesses (PF: 28.5%, 28.3-28.7%), of which 46,596 (35,662-65,234) would be MA (PF: 28.5%, 28.3-28.7%).ConclusionInfluenza vaccination is estimated to have averted influenza-associated illness outcomes even with low coverage in children aged 6-59 months in Suzhou. Increasing influenza vaccination coverage in this population could further reduce illnesses and hospitalizations.
