Seroprevalence of Human Fasciolosis in Pirabad, Lorestan Province, Western Iran.

BACKGROUND: The purpose of this study was to perform seroepidemiological investigation for determining the status of human fasciolosis in Pirabad Village, Lorestan Province, western Iran. METHODS: Blood samples were taken from residents of the village including 801 individuals. Sera were separated and stored at -20°C until used. The samples were analyzed using ELISA. RESULTS: Anti-Fasciola antibodies were detected in 6 (0.7%) individuals. Difference between age, sex and drinking or swimming in the surface water with seropositivity to fasciolosis was not significant. Out of 7 shepherds, 1 (14.3%) was seropositive. Due to the small number of shepherds, comprehensive statistical inference in this regard cannot be done. Significant difference was detected between seropositivity to fasciolosis and consuming local freshwater vegetables during the last 6 months (P=0.001). CONCLUSION: Metacercariae carrying local freshwater plants might be the main source of contamination because consumption of these kinds of vegetables was confirmed by all participants. Awareness of local communities regarding the danger of freshwater plant consumption, through health education programs, will decrease the risk of infection.

Determination of the causes of tendency toward red meat and meat products in the west of Iran.

BACKGROUND: Although meat constitutes an important part of many consumers' diet, its consumption has become a quiet controversial issue. Several factors are effective on tendency to red meat consumption. The 2007's report of the world Cancer Research Fund makes the recommendation to limit the consumption of red meat to less than 500 g per week. The aim of this study is to determine meat and meat products consumption and causes of tendency to red meat among people of Khorramabad city, Iran. METHODS: This cross- sectional study was carried out on 300 adults (178 women and 122 men; aged 19-70 years) of Khorramabad city, Iran. Red meat and processed meat intake (from a FFQ), demographic and causes of tendencies to red meat consumption (from a self-reported questionnaire) were evaluated. Statistical methods included independent t- test and one-way ANOVA. RESULTS: Consumption of red meat and meat products was 531.8 ± 543.5 g/w and 132.5 ± 251.1 g/w, respectively. The most important factors of tendencies toward red meat consumption were delectability, palatability, accessibility, cultural and traditional beliefs, and lack of food diversity in Lorestan province, animal husbandry, nomadic life, and hospitality. Red meat consumption was more common among men and lower in the income levels of $300. CONCLUSIONS: The results demonstrated that red meat consumption in adult people of the west of Iran was high. Since consumption of meat and meat products may create health concerns for people, it is necessary for policymakers to adopt effective strategies to advocate the use of fish and poultry.
