^^^^^^GREETINGS FROM^^^^^^^^^^ Ivan Suzman 47/10 [log in to unmask] Portland, Maine land of lighthouses 44 deg. F cold wind *********************************************************** Dear Listfriends, Here is part 9 of my 10-part report on the 102 listmembers who responded to the question, "Do you have a diabetic relative?" I found that THERE IS A GREATER PERCENTAGE OF PWP'S WITH AN AGE AT ONSET OF PD FROM 18 to 50 THAT HAVE A DIABETIC RELATIVE. Method: I was looking for a somewhat higher incidence of diabetic relatives among our younger-onset PWP's. I decided to divide the 102 PWP's into two groups, THOSE WITH ONSET OF PD BY AGE 50, and THOSE WITH ONSET OF PD after AGE 50. RESULTS---- 1. Of 43 younger-onset PWP's surveyed, 29, or 67.2%, have one or more diabetic relatives. Meanwhile, 14, or 32.8 %, have no known diabetic relative. 2. Of 44 later-onset PWP's surveyed, 25, or 56.8%, have one or more diabetic relatives. Meanwhile, 19, or 43.2%, have no known diabetic relative. . 3.. The average age at onset of PD symptoms is 53.4 years for those with no diabetic relatives, and 51.6 years of age for those with one or more diabetic relatives, among all 87 responses tallied. 15 respondents gave no age at onset of PD.
