  Purpose

The prevalence of preterm birth is rising in most western countries. The causes of preterm birth is not fully understood and seem to be multifactorial. The endocrine and metabolic aspects are scarcely investigated.The main purpose of this study is to test the hypothesis that endocrine and metabolic factors associate to preterm births.

Primary Outcome Measures:
  • The prevalence of PCOS [ Time Frame: one week after enrollment. ] [ Designated as safety issue: Yes ]
    The prevalence of PCOS will be assessed in both study groups and the difference between the groups will be reported.

  • The prevalence of Diabetes Mellitus [ Time Frame: one week after enrollment ] [ Designated as safety issue: Yes ]
    The prevalence of Diabetes Mellitus will be assessed in both study groups and the difference between the groups will be reported.


Secondary Outcome Measures:
  • Ovarian antral follicle count [ Time Frame: three years. ] [ Designated as safety issue: Yes ]
    Difference between study groups.

  • Difference in quality of life between study groups. [ Time Frame: four years ] [ Designated as safety issue: No ]
    Quality of life will be assessed by using Short form 36 Health Survey Questionnaire (SF- 36)

  • Serum levels of androgens [ Time Frame: one year ] [ Designated as safety issue: Yes ]
    Difference between study groups

  • Difference in anxiety between study groups. [ Time Frame: four years ] [ Designated as safety issue: No ]
    Anxiety will be assessed by using Spielberger State Anxiety Inventory Y1 and Y2 (STAI Y1 and Y2).

  • Serum levels of AMH [ Time Frame: One year ] [ Designated as safety issue: Yes ]
    Difference between study groups

  • Serum levels of glucose [ Time Frame: One year ] [ Designated as safety issue: Yes ]
    Difference between study groups

  • Serum levels of insulin [ Time Frame: One year ] [ Designated as safety issue: Yes ]
    Difference between study groups

Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

All women in municipalities having Namsos Hospital as their local Hospital and with preterm births from January 1999 to Descember 2006 were identifed by searching birth protocols. These women were invited to participate in the preterm birth study group. As controls we identified the first term birth occuring in time after each preterm birth. These women were invited to participate in the term birth study group.

Criteria

Inclusion Criteria:

  • One or more preterm birth in the given period of time
  • Having Namsos Hospital as their local Hospital during pregnancy

Exclusion Criteria:

  • Moved from the region of Mid- Norway at the time of the study
  • Lack of communication skills in Norwegian or English
  • Ongoing pregnancy
  • Ongoing breastfeeding
