A questionnaire with 15  questions was filled for every mother with a LBW and premature labor(case) and also for every mother with a delivery  of a term neonate  with a weight more than 2500 gr ( control). The interval between two  deliveries was the least.
Results: According to collected data about folic acid  in case group: 339 mothers (%50.9) complete use , 258 (%38.7) incomplete  and 69 mothers (%10.4) with no usage: In control group   respectively, 414 mothers (%62.1), 215 mothers (%32.3) and 37 mothers (%5.6), About multivitamin usage in  case group respectively:  504 cases (%77) -98 (14.7%) -64(%9.6). And in control group :545 (%82) -77 (%12) and 44 (%6 . 6). About iron tablet in case group, respectively : 543 (%81.5) -95 (%14.3)- 28 (% 4.2) and in control group:574 (%86.2) - 68 (%10.2) - 24 (%3.6).
