Abstract
Objective
This study aimed to investigate women’s adherence patterns to pelvic floor muscle exercises (PFME), their associated factors and within-pattern changes.
Methods
This was a secondary analysis using data collected from 647 women aged 55 years and older in the USA. Women were randomly assigned to either a 2-h class group or an equivalent content 20-min DVD group to receive PFME complemented with adherence enhancement strategies. Adherence was assessed at 3, 12 and 24 months using three self-reported items matching PFME parameters. The k-mean clustering and multinomial logistic regression were used to investigate adherence patterns and their associated factors, respectively. Descriptive statistics were used for within-pattern changes over time.
Results
Four adherence patterns, A, B, C and D, were identified. Women who displayed optimal adherence to all three aforementioned items, i.e. adherence pattern A, constituted 49.1%, 38.2% and 37.2% of women at 3, 12 and 24 months, respectively. Women with income > US$100,000 were more likely to display adherence pattern A within 12 months. Of women who had adherence pattern A at 3 months, 63.9% and 49.2% continued in this pattern at 12 and 24 months.
Conclusions
Fewer than half of women displayed adherence pattern A for 2 years. Early optimal adherence predicted women’s subsequent optimal adherence.
摘要
目的:本研究旨在调查女性对盆底肌运动(PFME)的坚持模式, 其相关因素和坚持模式内变化。
方法:该研究是一项二次分析, 收集了647名年龄在55岁及以上的美国女性的数据。女性被随机分配到2小时课程组或20分钟DVD等量内容组接受PFME坚持增强训练。在3个月、12个月和24个月时, 应用三个与PFME参数匹配的自我报告项目评估依从性。采用k-均值聚类和logistic回归分别调查坚持模式及其相关因素。描述性统计用于随时间变化的模式。
结果:确定了A、B、C和D四种坚持模式。在3个月、12个月和24个月的女性中, 49.1%、38.2%和37.2%的女性对上述三项匹配参数都表现出最佳的坚持, 即坚持模式A。收入为10万美元的女性在12个月内更有可能表现出坚持模式A。在3个月时遵循A模式的女性中, 63.9%和49.2%在12个月和24个月时继续遵循A模式。
结论:少于一半的女性显示坚持模式A超过 2年。早期最佳依从性预示着女性后续的最佳依从性。
