Effects of health promotion program of applying social marketing mix on knowledge about parasitic contamination and proper handling of washing vegetables among village health volunteer, Pho Thaen subdistrict, Ongkharak district, Nakho

Abstract

The purpose of this research was to study the effect of a health promotion program that applied social marketing mix (4P's, Product, Price, Place, Promotion) on knowledge of parasitic contamination in fresh vegetables and correct vegetable washing behavior. A total of 25 village health volunteers participated in the health promotion program, applying the social marketing mix for 5 weeks.  The questionnaires were used to measure knowledge and behavior. The data were analyzed by percentage, frequency, standard deviation, Paired sample t-test, and McNemar test at the significance level (p-value < 0.05). The results showed that after completing the program the village health volunteer's average knowledge scores increase not statistically significant (p-value > 0.05). The mean practice scores increased after completing the program (p<0.05). The proportion of village health volunteers with good knowledge and good behavior after receiving the program was not a statistically significant difference (p-value > 0.05) due to the regular practice of correct vegetable washing behavior. Health promotion programs that apply a social marketing mix can be used as a form of public advice, with the village health volunteer to reinforce their self-health and contribute to the prevention of parasite contamination in fresh vegetables rather than treatment.
