Study Description

Brief Summary

In this study, it is assumed that grip strength is associated with pelvic floor muscle strength. And the outcome of pelvic floor function can be predicted by referring to the status of pelvic floor muscle strength through the value of grip strength, which is labor-saving, time-saving and more convenient for evaluating pelvic floor muscle function. Moderate physical activity and increase the overall strength can activate the potential mechanism of pelvic floor muscle contraction at the same time may be a "core muscles" overall effect, that core muscles mainly includes transverse abdominal muscle, pelvic floor muscles and the muscles around the back, these muscles in the body movement to spontaneous collaboration contract pelvic floor muscles, enhancing pelvic floor muscle function, thus reducing the incidence of pelvic floor dysfunction.

Condition or Disease Intervention/Treatment Phase

    Detailed Description

    This study is a cross-sectional observational study, planned to enroll 2942 participants from Gynecology Outpatient Clinic. Uniformly trained physicians as investigators to collect indicators from questionnaires and physical examinations.

    Questionnaires may contain general information which include the patient's age, height, body weight before pregnancy and childbirth, weight gain during pregnancy, gestational age, pregnancy time, production time, high palace, delivery mode, neonatal birth weight, body length, blood sugar, blood fat, whether or not to use during pregnancy, childbirth, labor, perineal laceration, forceps midwifery, episiotomy and epidural data, pelvic floor cognition degree, physical activity levels, pelvic floor dysfunction score, pelvic floor functional impact score and sexual function score (including the prenatal and postnatal participants).

    Physical examinations will be performed without the results of the questionnaire, including stress tests, pelvic floor POP-Q staging, pelvic floor muscle strength by palpation, vaginal relaxation degree, grip strength value, rectus abdominis separation, waist circumference, waist-hip ratio, etc.

    Through univariate analysis of the general data of the patients, the related factors of female PFD were obtained, and the independent influencing factors of PFD were found by binary Logistic regression analysis (the dependent variable in this study was a dichotomous variable). The ROC curve was used to evaluate the predictive value of patients' overall strength level, physical activity level, body shape and other indicators on PFD outcome.

    Outcome Measures

    Primary Outcome Measures

    1. Pelvic floor muscle strength grading [through study completion,an average of one day]

      The result was recorded using the modified Oxford Grading scale, ranging from 0 to 5, which 0 represents no discernible pelvic floor muscle contraction and 5 represents a strong pelvic floor muscle contraction.

    2. Overall body strength measured by hand grip strength [through study completion,an average of one day]

      Grip strength index is used to evaluate adult muscle strength in Chinese National Physical Fitness Standards. Grip strength is an important indicator to evaluate an individual's upper limb strength and can reflect the overall muscle strength level which was used to evaluate the overall strength of participants.

    3. Physical activity levels [through study completion, an average of the past one week]

      International Physical Activity Questionnaire score- short from is used to measure the overall physical activity level. Paticipants volunteered for the study and filled out questionnaires to rate their levels of physical activity over the past week which can represent the overall physical activity level.

    4. Pelvic Floor Distress Inventory#PFDI-20#Questionnaire Score [through study completion, an average of the past 3 months]

      The Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20) is the short-form version of the Pelvic Floor Distress Inventory (PFDI).Since it is comprised of the UDI-6, POPDI-6, and the CRADI-8, the PFDI-20 includes 20 questions.The scale scores are found individually by calculating the mean value of their corresponding questions and then multiplying by 25 to obtain a value that ranges from 0 to 100.The sum of the 3 scales are added together to get the PFDI-20 summary score, which ranges from 0 to 300.

    5. FSFI-6 Questionnaire Score [through study completion, an average of the past four weeks]

      The 6-item Female Sexual Function Index (FSFI) is a short form of the original 19-item FSFI that measures sexual function in women.It comprises six domains: desire, arousal, lubrication, orgasm, satisfaction, and pain. Desire and satisfaction items are rated on a 5-point Likert scale, ranging from 1 to 5, and the other items are rated on a 6-point Likert scale, ranging from 0 to 5. Total scores range from 2 to 30, with lower scores indicating worse sexual functioning.
