Nutrient intake and urinary incontinence in Korean women: A propensity score-matched analysis from the Korea National Health and Nutrition Examination Survey data

Role of dietary food intake patterns, anthropometric measures, and multiple biochemical markers in the development of pregnancy-specific urinary incontinence in gestational diabetes mellitus

OBJECTIVES

The aim of this study was to assess maternal dietary food intake patterns, anthropometric measures, and multiple biochemical markers in women with gestational diabetes mellitus and pregnancy-specific urinary incontinence and to explore whether antedating gestational diabetes mellitus environment affects the pregnancy-specific urinary incontinence development in a cohort of pregnant women with gestational diabetes mellitus and pregnancy-specific urinary incontinence.

METHODS

Maternal dietary information and anthropometric measurements were collected. At 24 wk of gestation, with a fasting venipuncture sample, current blood samples for biochemical markers of hormones, vitamins, and minerals were analyzed. The groups were compared in terms of numerical variables using analysis of variance for independent samples followed by multiple comparisons.

RESULTS

Of the 900 pregnant women with complete data, pregnant women in the gestational diabetes mellitus pregnancy-specific urinary incontinence group had higher body mass index during pregnancy, arm circumference, and triceps skinfold than the non-gestational diabetes mellitus continent and non-gestational diabetes mellitus pregnancy-specific urinary incontinence groups, characterizing an obesogenic maternal environment. Regarding dietary food intake, significant increases in aromatic amino acids, branched-chain amino acids, dietary fiber, magnesium, zinc, and water were observed in pregnancy-specific urinary incontinence group compared with the non-gestational diabetes mellitus continent group. Serum vitamin C was reduced in the gestational diabetes mellitus pregnancy-specific urinary incontinence group compared with the non-gestational diabetes mellitus pregnancy-specific urinary incontinence group.

CONCLUSIONS

This study emphasizes the necessity for a comprehensive strategy for gestational diabetes mellitus women with pregnancy-specific urinary incontinence in terms of deviation in maternal adaptation trending toward obesity and maternal micronutrients deficiencies.

Clinical Factors Associated With the Feeling of Incomplete Bladder Emptying in Women With Little Postvoided Residue

Purpose

To investigate the clinical factors associated with the feeling of incomplete bladder emptying in female patients with lower urinary tract symptoms (LUTS).

Methods

Records were obtained from a prospectively maintained database for 353 female patients without a history of treatment for LUTS. Patients with comorbidities that may affect voiding function and with postvoid residual (PVR) volume >20 mL or PVR volume-to-bladder capacity ratio of >10% were excluded. Finally, 211 patients were eligible for the study.

Results

Patients were stratified according to the severity of the feeling of incomplete emptying: non-severe group (n=147, 69.7%) and severe group (n=64, 30.3%). The severe group showed longer time to maximum flow rate (Qmax) and greater total overactive bladder symptom score (OABSS). No differences in age, PVR volume, and diagnosis of overactive bladder (OAB) were found between the 2 severity groups. Multivariable analysis identified the severity of the feeling of incomplete emptying to be significantly associated with time to Qmax and minimum volume of voids. Time to Qmax was identified as a significant predictor of severe symptoms in women with OAB. In addition, the feeling of incomplete emptying, total OABSS, and minimum volume of voids were significantly associated with quality of life.

Conclusions

Female patients with the feeling of incomplete emptying who have insignificant PVR volume exhibited severe voiding symptoms and low quality of life. The treatment strategy should be focused on improving the minimum volume of voids and shortening the time to Qmax.
