Prevalence and Associated Factors of Urinary Incontinence among Chinese Adolescents in Henan Province: A Cross-Sectional Survey

Is there an association between physical activity and lower urinary tract symptoms in adolescent girls? Results from the Avon Longitudinal Study of Parents and Children

INTRODUCTION AND HYPOTHESIS

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.

METHODS

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).

RESULTS

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.

CONCLUSIONS

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.

HPV-infection status and urinary incontinence: a population-based analysis of the NHANES 2005-2016

PURPOSE

Urinary incontinence is a common condition and reduces the quality of life. The purpose of this study was to assess the association between HPV infection and urinary incontinence among adult women in the USA.

METHODS

We examined a cross-sectional study using the National Health and Nutrition Examination Survey database. Women who had valid HPV DNA vaginal swab test results and answered the questionnaire about urinary incontinence were selected from six consecutive survey cycles (2005-2006 to 2015-2016). The association between HPV status and urinary incontinence was analyzed using weighted logistic regression. Models adjusted for potential variables were established.

RESULTS

In total, 8348 females aged between 20 and 59 years old were enrolled in this study. 47.8% of participants had a history of urinary incontinence and 43.9% of women were HPV DNA positive. After adjusting for all confounders, women with HPV infection were less likely to have urinary incontinence (OR = 0.88, 95%CI 0.78-0.98). Low-risk HPV infection correlated with a lower incidence of incontinence (OR = 0.88, 95%CI 0.77-1.00). For women aged below 40 years, low-risk HPV infection negatively correlated with stress incontinence (20-29ys: OR = 0.67, 95%CI 0.49-0.94; 30-39ys: OR = 0.71, 95%CI 0.54-0.93). However, low-risk HPV infection positively correlated with stress incontinence (OR = 1.40, 95%CI 1.01-1.95) for women 50-59 years old.

CONCLUSION

This study revealed a negative association between HPV infection and urinary incontinence in females. Low-risk HPV correlated with stress urinary incontinence, with the reverse trend for participants of different ages.
