Scant epidemiological studies have been carried out on the prevalence of skin diseases in population of Iran. This study was performed to assess the prevalence of skin diseases in the of rural areas Hamedan, in the west of Iran in 2002. A cluster random sampling was followed. The survey included 9450 rural inhabitant of all ages and both sexes from representative of 33 villages of Hamedan governorate in the west of Iran. The data were collected through personal interview and examination at homes in 2002. This study showed that overall prevalence of skin diseases is 27% and dermatitis by 37.5%, disorders of skin color 36.3%, actinic disorders 16.5%, nail disorders 13% and acne 11.7%. They were the five common diagnoses. Incidence of skin diseases in Hamedan province is high and is one of the public health problems that need planning for reduction of size of these disorders and its burden on community as a whole.

   Introduction Top

Skin diseases and their complications are a significant burden on the nations. There are probably at least 2000 different skin conditions that might present to the dermatologists.[1] Distribution of skin diseases differs from country to country and even city to city. Some factors like genetic, environment, race, occupation, nutrition and habits can influence the pattern of skin diseases. [1],[2],[3],[4] Dermato-epidemiology refers to study of the epidemiology of dermatological disorders.[5] One of the need assessments in dermatology is to establish the size and nature of the dermatological needs based on epidemiological data. Epidemiology is often used to describe the distribution, causes and burden of diseases in human population. It also helps health service planners. We carried out a survey to determine the prevalence of skin diseases in rural areas of Hamedan province in the west of Iran.

   Materials and methods Top

A cluster random sampling was carried out on 9450 persons in 33 rural areas of Hamedan in the west of Iran in 2002. This epidemiological survey was done by a specialized team, including four dermatologists, a dermatopathologist, a biostatistician and two general practitioners. Whole body skin was examined by the dermatologists and diagnosis of the lesions was based on clinical observations. In lesions where clinical diagnosis were at suspect, biopsy or smear was taken and diagnosis was made based on laboratory finding. Analysis of collected data was done by Epi info 6 software.

   Results Top

The age range of all examined people was between 1-75 years including 58.3% of males and 41.7% females. Overall, proportion of the population found to have any form of skin disease was 27%. Also we have found 65 kinds of skin disorders that for simplicity has been grouped into 11 categories. The prevalence of each group of skin disorders is shown in [Table - 1]. As showed in [Table l], dermatitis and allied conditions (37.5%) was the commonest and papulo-squamous disorders like psoriasis and lichen planus (0.15%) has lowest prevalence. Dermatitis and allied conditions, disorders of skin color, actinic disorders, nail disorders and acne were the five most common skin disorders [Table l]. Duration of 82.2% and 17.8% of skin lesions were above and below 6 months respectively. Head and neck (66%) were the most common location of these lesions. Eighty two percent (82%) of these disorders were found under the ages of 40 years.

   Discussion Top

Although factors that influence on the incidence and distribution of skin diseases are genetic, race, geographical conditions, occupation, diet, habits and public health [1],[2],[3],[4],[5] but in most countries the prevalence of skin diseases is not known or well addressed. We do not know the precise model of prevalence of skin diseases and relation between needs, supply and demands for dermatological care. Also we do not know how much of a public health problem is skin diseases are. For this reason, we decided to carry out this epidemiological survey. The overall prevalence of skin disorder was 27.1% that comprises 65 kinds of various skin disorders that we have grouped in

[Table l] We found that dermatitis and allied conditions (37.5%) was the most common cause of skin diseases. In comparison to other studies in USA 19%,[6] England 19%[7] and Singapore 34%,[8] it has a high prevalence. This variation may be due to lack of education, genetic factors, occupation and chance contact with different physical and chemical agents in the studied population. On the other hand, the first five common skin diseases in our studied population can be compared with other studies as is shown in [Table - 2][9],[10],[11],[12],[13],[14],[15] There are differences between the prevalence of skin diseases in various areas of the world that may be due to diverse factors. Some studies have observed few or more melanocytic nevus which was considered by them as a risk factor for melanoma.[16],[17],[18],[19],[20] We concluded that the prevalence of skin diseases in our areas is high and is one of the great public health problems that have a significant burden on our nation. So, we think increased public and professional awareness of dermatological care could decrease the size of these disorders and its burden in our community.
