background: in northeastern iran there is an area of high incidence of esophageal cancer which is populated by residents of turkmen ancestry. several environmental risk factors for esophageal cancer have been proposed, but the roles of familial and genetic factors have not been studied extensively in the turkmen population. materials and methods: we evaluated the importance of familial risk fac...

Most common diseases demonstrate familial aggregation; the ratio of the risk for relatives of affected people to the risk for relatives of unaffected people (the familial risk ratio)) > 1. This implies there are underlying genetic and/or environmental risk factors shared by relatives. The risk gradient across this underlying 'familial risk profile', which can be predicted from family history an...

objective: although numerous studies have found higher rates of abortion and still births following consanguinity (familial marriages), the question of whether consanguinity significantly increases the risk of neonatal death has inadequately been addressed.this study aims to evaluate familial marriage effects on neonatal death in rural areas in iran. materials and methods: i n this nested case-...

CONTEXT Although the heritability of atrial fibrillation (AF) is established, the contribution of familial AF to predicting new-onset AF remains unknown. OBJECTIVE To determine whether familial occurrence of AF is associated with new-onset AF beyond established risk factors. DESIGN, SETTING, AND PARTICIPANTS The Framingham Heart Study, a prospective community-based cohort study started in 1...

BACKGROUND It has been suggested that family history information may be effective in motivating people to adopt health promoting behaviour. The aim was to determine if diabetic familial risk information by using a web-based tool leads to improved self-reported risk-reducing behaviour among individuals with a diabetic family history, without causing false reassurance among those without a family...

Background: Hormones and genetics play a critical role in breast cancer development, determining the association between plasma hormones and breast cancer risk among familial and non-familial females may provide insight into the etiology of breast cancer. Material and Methods: 140 postmenopausal females during the period between June 2007 and May 2011 were enrolled in this study, 83 were breast...
