Abstract

Introduction: Ametropias are the first reason for ophthalmological consultations of school children. It is a public health problem and one of the main causes of visual impairment in the world.

Purpose: To study the prevalence and associated factors of ametropias among primary school children aged 6 years old and over in the commune of Parakou in 2020.

Patients and Methods: This was a cross-sectional, descriptive and analytical study that took place from july 1st to 30 th september 2020. It involved school children aged at least of 6 years old, residing in the commune of Parakou and enrolled in the various elementary school in this commune for the 2019 - 2020 school year..

Results: A total of 810 children aged 6 - 15 years old had participated to the study. The prevalence of ametropias was 19.87%. The 6 - 7-years-old age group had the most ametropia (34.40%). A female predominance had been objectified (52.23%). Hyperopia was the most represented refractive abnormally (42.68%), followed by astigmatism (39.49%) and myopia (22.93%). Ocular pruritus (p = 0.000) and studying with poor luminosity (p = 0.001) were statistically significantly associated with ametropia. Age (p = 0.0164), sex (p = 0.0095), father's socioeconomic status index (p = 0.0002), mother's socioeconomic status index (p = 0.013), and parental history of wearing corrective lenses (p = 0.0178) were statistically significantly associated with hyperopia. On the other hand, history of prematurity (p = 0.0428) and malnutrition (p = 0.000) were statistically significantly associated with astigmatism and only malnutrition (p = 0.0001) was statistically associated with myopia. However, 3.82% of ametropes were amblyopic.

Conclusion: Ametropia still be a major concern in the children school setting because of its significant prevalence (19.87%) and its complications, which are preventable with early diagnosis and management.
