Insights
High rates of delayed childhood vaccination were observed. Factors like maternal health issues, child hospitalization, and poor mother-provider relationships significantly impact vaccination timeliness.
Area of Science:
- Pediatric Health
- Public Health
- Epidemiology
Background:
- Vaccination is crucial for child health and disease prevention.
- Understanding factors contributing to vaccination delays is essential for improving coverage rates.
- Previous research indicates various socioeconomic and healthcare-related factors influence immunization schedules.
Purpose of the Study:
- To identify and analyze factors associated with delayed vaccination in children up to two years of age.
- To provide insights for interventions aimed at improving timely childhood immunizations.
Main Methods:
- A cross-sectional study utilizing primary data from 388 children born in 2015.
- Descriptive statistics (absolute and relative frequencies) were used for data summarization.
- Cox proportional risk regression analysis was employed to identify factors associated with vaccination delay.
Main Results:
- A high delayed vaccination rate of 88.66% was found.
- Significant factors associated with delayed vaccination included: maternal health problems (HR: 0.68), child hospitalization (HR: 1.52), poor mother-healthcare professional bond (HR: 1.75), and parental decision to delay vaccination (HR: 1.56).
- Maternal health issues were associated with a reduced risk of delay, while child hospitalization and maternal perception of care were associated with increased risk.
Conclusions:
- Healthcare-related factors, including maternal health during delivery, child hospitalization, and the mother's relationship with healthcare providers, significantly influence the timeliness of childhood vaccinations.
- Targeted interventions addressing these factors are necessary to improve vaccine uptake and protect child health.
- The findings underscore the importance of a strong mother-provider relationship in ensuring adherence to immunization schedules.
Objective:
To analyze factors associated with vaccination delay in children up to 2 years of age.
Methods:
Cross-sectional study with primary data from a probabilistic sample of 388 children born in 2015. The data were described using absolute and relative frequencies. For the analysis of factors associated with vaccination delay, Cox proportional risk regression was performed, considering the time from birth to the first vaccination delay as a dependent variable and as sociodemographic, economic, behavioral aspects related to health services as independent variables.
Results:
The delayed vaccination rate was 88.66%. Variables associated with delayed vaccination were: mother's health problems during delivery or in the first 7 days (HR: 0.68; 95% CI: 0.48-0.96); hospitalization of the child in the first 2 years of life (HR: 1.52; 95% CI: 1.10-2.11); mother's poor bond with health professionals at the health unit (HR: 1.75; 95% CI: 1.01-3.03); purposeful decision to delay or not to vaccinate the child (HR: 1.56; 95% CI: 1.14-2.13).
Conclusions:
The factors associated with health care, such as the mother's health problems, the child's hospitalization in the first 2 years of life, and the bond between the mother and the health professionals affect the timeliness of vaccine doses.
