Objective
  The authors were engaged in an adolescent peer leader project. While the main target of this peer education was adolescent students, evaluation of a ripple effect on local residents is a necessary step for the development of peer education activities. Accordingly, the object of this study was to assess whether adolescent peer education had improved the health consciousness and knowledge of the local residents of a rural area of Mexico.
Method
  The subjects were residents aged between 12 and 69 years living in the districts covered by 3 public health centers in the Poza Rica district, Veracruz State. A list of residents in this age group was prepared, and 50% of all the households in each area were randomly selected. From March to April 2010, before the start of the activities, an interview survey was conducted.
Results
  Regarding the question on self-esteem, the percentage of respondents who reported being as capable as most other people significantly increased (p < 0.001). On lifestyle, the percentage of people who reported consuming vegetables and fruits daily or once in 23 days significantly increased (p < 0.001). Regarding knowledge about STDs and contraception, the rate of correct answers about STDs decreased in the second measurement, while the percentage of correct answers about contraception significantly increased. On peer education, the percentage of people who had heard of the term “peer educator” significantly increased (p < 0.001).
Conclusion
  The current adolescent peer education activity undertaken in a rural area of Mexico improved self-esteem and health consciousness in other residents of the community. The ripple effect on the entire community was limited for knowledge of STDs and contraception. However it was suggested that the increase of motivation for attendance to health education in the community could be a stepping stone to the spread of knowledge.
