Lower urinary tract symptoms (LUTS) are common among adolescent girls. Physical activity (PA) has been implicated as both a risk (high-impact PA) and protective factor (low-impact, moderate to vigorous intensity PA) for LUTS in adult women, but its role in adolescent girls is unclear. This study investigated the prospective association between physical activity and LUTS risk in adolescent girls.
The sample comprised 3,484 female participants in the Avon Longitudinal Study of Parents and Children. Multivariate logistic regression models were used to examine daily minutes of moderate to vigorous PA (MVPA) at ages 11 and 15 years in relation to LUTS at ages 14 and 19 respectively. MVPA was assessed by 7-day accelerometer data. LUTS were assessed by questionnaire. MVPA were analyzed as continuous (minutes/day) and categorical variables (<10th percentile, 10-89th percentile, ≥90th percentile).
Prevalence of LUTS ranged from 2.0% for bedwetting to 9.5% for nocturia at age 14 and from 2.0% for straining to urinate to 35.5% for interrupted urine flow at age 19. Physical activity was not associated with LUTS at either time-point.
Given the prevalence of LUTS in female adolescent populations, although this study did not find an association with accelerometer-measured MVPA, other aspects of PA that may serve as risk or protective factors deserve investigation.
下尿路症状（LUTS）在少女中较为常见。身体活动（PA）已被认为是成年女性 LUTS 的风险因素（高冲击性 PA）和保护因素（低冲击性、适度至剧烈强度 PA），但其在少女中的作用尚不清楚。本研究旨在探讨青少年女性身体活动与 LUTS 风险的前瞻性关联。
该样本包括 3484 名参加阿冯纵向研究父母与子女的女性参与者。采用多变量逻辑回归模型，分别在 11 岁和 15 岁时，分析每日中等至剧烈强度体力活动（MVPA）分钟数与 14 岁和 19 岁时 LUTS 的关系。MVPA 通过 7 天加速度计数据进行评估。LUTS 通过问卷调查进行评估。MVPA 分别以连续（分钟/天）和分类变量（<10 百分位，10-89 百分位，≥90 百分位）进行分析。
14 岁时，LUTS 的患病率从遗尿的 2.0%到夜尿症的 9.5%不等，19 岁时，从排尿困难的 2.0%到尿流中断的 35.5%不等。身体活动与任何时间点的 LUTS 均无关。
鉴于女性青少年人群中 LUTS 的患病率，尽管本研究未发现与加速度计测量的 MVPA 有关，但其他可能作为风险或保护因素的 PA 方面值得进一步研究。
