بررسی میزان شیوع راشیتیسم در مناطق آستانه اشرفیه، صومعه سرا در استان گیلان

ABSTRACT Deficiency of vitamin D especially in growing children can cause rickets (1).It has been shown that people who do not get enough sunshine may be prone to rikets (2) . The aim of this project was to find the prevalence of rickets in Gilan which is, from the climate point of view, a place with rainy and cloudy environment in most of the year. The method for carring out this research was cluster sampling (3). Children and infants of 0-5 years of age were examined to find the signs of rickets(4).The children who were prone to rickets referred to a clinic for final examination , radiography, and laboratory analysis .Results showed that 1.26% of total population of Astaneh and 9% of total population of Somehsara had rickets Our results were compared with those of another study which had been carried out by Rezaee and Keshavarz in rural areas of Sirjan in Kerman (6). Although the authors did not aim to find rickets,they showed that deficiency of vitamin D was 5% which was more than that in our results.
