Objective:
To investigate the present situation of
pelvic floor muscle strength, and to analyze the factors affecting
pelvic floor muscle strength.
Methods:
The data of
patients who were admitted into the general
outpatient department of
gynecology,
Peking University People's
Hospital from October 2021 to April 2022 were collected, and the
patients who met the exclusion criteria were included in this cross sectional study. The
patient's age, height, weight,
education level,
defecation way and
defecation time,
birth history, maximum
newborn birth weight, occupational
physical activity,
sedentary time,
menopause,
family history and
disease history were recorded by
questionnaire. Morphological indexes such as
waist circumference,
abdomen circumference and
hip circumference were measured with tape
measure. Handgrip strength level was measured with
grip strength instrument. After performing routine
gynecological examinations, the
pelvic floor muscle strength was evaluated by
palpation with modified Oxford grading scale (MOS). MOS grade>3 was taken as normal group and ≤3 as decreased group. Binary
logistic regression was used to investigate the related factors of deceased
pelvic floor muscle strength.
Results:
A total of 929
patients were included in the study, and the average MOS grade was 2.8±1.2. By univariate
analysis,
birth history, menopausal
time,
defecation time, handgrip strength level,
waist circumference and
abdominal circumference were related to the decrease of
pelvic floor muscle strength (all P<0.05). By binary
logistic regression analysis, the level of handgrip strength (OR=0.913, 95%CI 0.883-0.945; P<0.001) was correlated with normal
pelvic floor muscle strength;
waist circumference (OR=1.025, 95%CI 1.005-1.046; P=0.016),
birth history (OR=2.224, 95%CI 1.570-3.149; P<0.001),
sedentary time> 8 hours (OR=2.073, 95%CI 1.198-3.587; P=0.009) were associated with the decrease of
pelvic floor muscle strength.
Conclusions:
The level of handgrip strength is related to the normal
pelvic floor muscle strength of
females, while the
waist circumference,
birth history and
sedentary time>8 hours are related to the decrease of
pelvic floor muscle strength of
females. In order to prevent the decrease of
pelvic floor muscle strength, it is necessary to carry out relevant
health education, enhance
exercise, improve the overall strength level, reduce daily
sedentary time, maintain symmetry, and carry out comprehensive overall intervention to improve
pelvic floor muscle function.
