Effect of intensive education on knowledge, attitudes, and practices regarding upper respiratory infections among urban Latinos

Abstract

Background: Although upper respiratory infections (URIs) take a major social and economic toll, little research has been conducted to assess the impact of educational interventions on knowledge, attitudes, and practices of community members regarding prevention and treatment of URIs, particularly among recently immigrated urban Latinos who may not be reached by the mainstream healthcare system.

Objectives: The objective of this study was to assess the impact of a culturally appropriate, home-based educational intervention on the knowledge, attitudes, and practices regarding prevention and treatment of URIs among urban Latinos.

Methods: Using a pretest-posttest design, Spanish-language educational materials available from sources such as the Centers for Disease Control and Prevention were adapted based on feedback from community focus groups and provided to households during an in-person home visit every 2 months (generally three to four visits). Outcome data regarding knowledge, attitudes, and practices were collected in home-based interviews using an 85-item instrument adapted and pilot tested from three other validated instruments. Nonparametric and multiple linear regression analyses were used to summarize data and identify predictors of knowledge scores.

Results: Four hundred twenty-two households had complete data at baseline and 6 months. Knowledge and attitude scores were improved significantly, and use of alcohol hand sanitizer and rates of influenza vaccine were increased significantly (all p <.01).

Discussion: Although this home-based educational intervention was successful in improving knowledge, attitudes, and self-reported practices among urban Latinos regarding prevention and treatment of URIs, further research is needed to determine the cost-effectiveness of such a person-intensive intervention, the long-term outcomes, and whether less intensive interventions might be equally effective.
