16 mai 2014 mis à jour par: Josue Fernandez Carnero, Universidad Rey Juan Carlos

Low Back Pain Disability, Intensity and Widespread Pain and Relationship to Postpartum Depression

The aims of this study are to investigate whether pelvic pain and low back pain disability are associated with postpartum depression and to compare the prevalence between women without Low back pain and disability and women with Low Back Pain (LBP) and disability every trimester, and correlate postpartum Depression and some clinical and biopsychosocial variables: subgroups of LBP, disability, pain intensity, pain widespread and nationality, in a cohort of Spanish women at 2 months postpartum.

Les conditions

Description détaillée

295 pregnant women will formed the cohort, during all pregnancy and two months after delivery. The Edinburgh Postnatal Depression Scale was used to evaluate depressive symptoms at 2 months postpartum. The LBP will be evaluated based on self-administrated questionnaire, and the patients with LBP will be classified in to lumbopelvic groups according to mechanical assessment of the lumbar spine, pelvic pain provocation tests, standard history, pain intensity on visual analogue scale, spread of pain through pain drawings and Oswestry index was used to evaluated the disability. Logistics regression analysis will performed to explain the predictors of depression.

Principaux critères de jugement

Mesure des résultats	Description de la mesure	Délai
Post-Partum Depression Délai: change from baseline in postpartum depression at 2 months after delivery	Depressive Symptoms is assessed through the Edinburgh Postnatal Depression Scale (EPDS) (translation - Spanish). It´s a 10-item self-report scale specifically designed to screen for postpartum depression. The scale rates the intensity of depressive symptoms present within the previous 7 days. A cutoff score of ≥10 in the tests is to be used for screening purposes in primary care. When selecting this threshold the sensitivity for detection of major depression increased to almost 100% and the specificity to 82%. The participants filled it in at the first visit and two months postpartum.	change from baseline in postpartum depression at 2 months after delivery

Mesures de résultats secondaires

Mesure des résultats	Description de la mesure	Délai
Pain Scores in the visual analogue scale Délai: Participants will be followed for the duration of pregnant up to 36 weeks	The Visual Analog Scale (VAS) is used to assess pain intensity (0-100 mm, where "0" corresponded to "no pain" and "10" to the worst imaginable pain).All participants were evaluated during all their pregnancy: in the first trimester (for 12 to 16 weeks), in the second trimester (for 22 weeks) and in the third trimester (for 36 weeks)	Participants will be followed for the duration of pregnant up to 36 weeks
Low back pain disability Délai: Participants will be followed for the duration of pregnant up to 36 weeks	Disability is measured with the Oswestry Low Back Pain and Disability Questionnaire (ODQ) to compare the prevalence between women without LBP and disability and women with LBP pain and disability every trimester. All participants were evaluated of low back disability during all their pregnancy: in the first trimester (for 12 to 16 weeks), in the second trimester (for 22 weeks) and in the third trimester (for 36 weeks).	Participants will be followed for the duration of pregnant up to 36 weeks
Pain drawing area Délai: Participants will be followed for the duration of pregnant up to 36 weeks	Participants completed detailed pain drawings representing a human body (American Academy in Physical Medicine and Rehabilitation. 2001) to assess pain location (lumbar, pelvic and symphysis pubis). To score the spread of pain, these human body views are uniformly divided into a total of 220 squares, each measuring 0.5 x 0.5 cm. .	Participants will be followed for the duration of pregnant up to 36 weeks
