  1. Seasonal ataxia in western Nigeria : evaluation of the impact of health education on hospital prevalence.

    Article - En anglais

    Study objective

    The study aimed to evaluate the impact of focused health education on the hospital prevalence of a seasonal ataxic syndrome which occurs exclusively in people of low income after eating the larvae of Anaphe venata Butler (Lepidoptera, Notodontidae).

    Design

    Retrospective impact evaluation study.

    Setting

    Wesley Guild Hospital, Ilesha, western Nigeria from where the syndrome was first described.

    Methods

    Hospital workers were informed of recent research findings on the aetiological role of Anaphe venata larvae consumption in the annual epidemics of seasonal ataxia.

    The number of admissions for seasonal ataxia in the pre-intervention years (1990 and 1991) and in the intervention years (1992 and 1993) were extracted from records.

    The toal number of casualty admissions between July and November of each year were also obtained.

    The period prevalence rates of the disease in each year of the study period were calculated and compared.

    Results

    The pre-intervention prevalence rates were 1.27% and 1.59% for 1990 and 1991 respectively.

    The prevalence rates in the intervention years of 1992 and 1993 were 0.58% and 0.006%, representing a 65.5% reduction between 1991 and 1992, and a 99% reduction between 1992 and 1993.

    Conclusion

    The health education technique used is an inexpensive but effective way of providing the intervention needed for the control of nutrition related diseases in the poor, largely illiterate segment of communities that are most vulnerable.
