Recruiting immigrant populations, particularly recent arrivals, is challenging due to lack of sampling frames and other factors. The purpose of this paper is to report the feasibility of using a quasi-random sampling strategy for recruiting recent Latin American (LA) immigrants.

The initial recruitment strategy included random selection of two census tracts (CTs) with high concentrations and numbers of recent LAs in Toronto, and door-to-door recruitment. Based on challenges encountered this strategy was modified by consulting trusted community members and recruiting participants residing in selected CTs using cultural venues.

Door-to-door recruitment of the target group is difficult. Challenges included accessing individuals living in apartment buildings, lack of trust and fear of deportation, transitory residency, and difficulty recruiting very recent arrivals. The modified strategy was more efficient and yielded higher recruitment rates, and was more acceptable to participants.

The limited timeframe of the study and lack of timely census data may have prevented full exploration of study methodologies.

The study demonstrated that recruitment rates of recent immigrants and refugees can be improved by randomly selecting CTs with high concentrations and numbers of recent immigrants and using culturally appropriate recruitment strategies. These groups may not be homogeneously distributed in selected geographic areas (e.g. CTs); it may be necessary to focus on pockets of high concentration as identified by community members who are familiar with the area.

The purpose of this paper is to review evidence related to the factors that influence people's understanding of health information and how miscommunication of health information can jeopardize people's health.

A literature review was conducted of English language articles, cited in major literature databases from the last 40 years, which describe factors related to comprehension of health information. A total of 93 articles were included.

The paper finds that health communication should take into consideration the role of the following factors on the processing and interpretation of health information: health literacy, format presentation of information, and human cognitive biases and affective/personal influences.

Health communication is a major component of health care. Every health care encounter involves exchange of information, which is intended to enhance people's knowledge in order to assist them to make an informed decision about their health care. However, the mere act of providing information does not guarantee comprehension. People's comprehension of information depends on several factors, including health literacy and numeracy skills, the format presentation of health information and human cognitive biases in the information processing and interpretation. Ineffective health communication can result in a wide range of direct and indirect health consequences including failure to understand and comply with treatment, poorer health status, increased risk of injuries, increased hospitalization, and decreased use of preventive services.

This paper provides health professionals and educators with an overview of important issues related to health communication and highlights strategies that facilitate effective communication to help people to make informed decisions about their health care.
