when you give yourself multiple items with the max health attribute and equip them it doesnt add more effectiveness
for example if i have boots with +10 max health and a sword with +10 max health i only get +10 max health were-as i should get 10 + 10 or 20 extra max health

here is command to give nearest droped item the max health attribute of +20 hp:
/entitydata @e[type=Item,c=1] {Item:{tag:{AttributeModifiers:[
{AttributeName:"generic.maxHealth",Name:"generic.maxHealth",Amount:20,Operation:0,UUIDLeast:941137,UUIDMost:134331}
]}}}
As @unknown stated, you cannot use multiple of the same UUID for modifiers. The IDs must be "Universally Unique". Each of the maxHealth modifiers will have to have a unique UUID.
Please provide the command you're using.
