Nutrient composition of the diet and the development of overactive bladder: a longitudinal study in women.
Journal - Neurourology and urodynamics (United States )
AIMS: Evidence for an association between diet and the symptom syndrome overactive bladder (OAB) would be valuable in understanding its aetiology. The present study investigates prospectively the association between the nutrient composition of the diet and the onset of OAB. METHODS: A random sample of community dwelling women aged 40 years or over was studied. Baseline data on urinary symptoms and diet were collected from 6,371 women using a postal questionnaire and food frequency questionnaire. Follow-up data on urinary symptoms were collected from 5,816 of the women in a postal survey 1 year later. Logistic regression was used to investigate the association of diet (daily intakes of energy, macro and micronutrients) with 1 year incidence of OAB. RESULTS: There was evidence that three nutrients may be associated with OAB onset. Higher intakes of vitamin D (P = 0.008), protein (P = 0.03), and potassium (P = 0.05) were significantly associated with decreased risks of onset. Although overall the associations with vitamin B6 and niacin were not significant (P = 0.08 and P = 0.13), there was some evidence of a decreased risk of onset with higher intakes. CONCLUSIONS: The results from this prospective study suggest possible aetiological associations between certain nutrients and OAB onset. The findings need confirmation and possible mechanisms to explain these associations need further investigation.Copyright 2004 Wiley-Liss, Inc.

Diet as a risk factor for the development of stress urinary incontinence: a longitudinal study in women.
Journal - European journal of clinical nutrition (England )
OBJECTIVE: To assess the association between diet and the onset of stress urinary incontinence (SUI) in women aged 40 y plus. DESIGN AND SETTING: The Leicestershire MRC Incontinence Study - a prospective longitudinal study of the prevalence, incidence and aetiology of urinary symptoms. SUBJECTS AND METHODS: A total of 5816 women aged 40 y plus and living in the community. Urinary symptoms were reported in a postal questionnaire at baseline and at 1-y follow-up. Dietary intake was assessed in a food frequency questionnaire at baseline. RESULTS: Intakes of total fat, saturated fatty acids and monounsaturated fatty acids were associated with an increased risk of SUI onset 1 y later. Of the micronutrients studied, zinc and vitamin B12 were positively associated with SUI onset. CONCLUSION: The results from this prospective study suggest there may be an aetiological association between certain components of the diet and the onset of SUI. The findings need confirming and possible mechanisms to explain these associations need further investigation.

The association of diet and other lifestyle factors with the onset of overactive bladder: a longitudinal study in men.
Journal - Public health nutrition (England )
OBJECTIVE: To investigate associations between diet and non-dietary lifestyle factors and the onset of overactive bladder (OAB) in men. SUBJECTS: Random sample of community-dwelling men aged 40 years plus. DESIGN AND METHODS: Baseline data on urinary symptoms and diet were collected from 5454 men using a postal questionnaire and a food-frequency questionnaire. Follow-up data on urinary symptoms were collected from 4887 men in a postal survey one year later. Logistic regression analysis was used to investigate diet and lifestyle factors associated with onset of OAB in the men without OAB at baseline. RESULTS: There was a highly significant negative association between beer intake at baseline and subsequent OAB onset (P=0.001), with reduced risk at all levels of intake compared with those who seldom/never drank beer. Adjustment for total alcohol intake (g ethanol day(-1)) reduced the significance of the association (P=0.02). None of the food groups studied was associated with OAB onset, with the possible exception of potatoes (P=0.05), which showed an increased risk of onset at the highest level of consumption. Physical activity, smoking and obesity were not significantly associated. CONCLUSIONS: While most diet and lifestyle factors were not associated with OAB onset, the evidence from this prospective longitudinal study suggests that beer may have a protective role in the development of OAB. This could be due to a non-alcoholic ingredient as well as the alcohol content.

An investigation into nonresponse bias in a postal survey on urinary symptoms.
Journal - BJU international (England )
OBJECTIVE: To investigate nonresponse bias in a postal survey on urinary symptoms in people aged >or= 40 years. SUBJECTS AND METHODS: Nonresponders to a postal survey on incontinence and other urinary symptoms were studied. A random sample of 1050 nonresponders (stratified for age and sex) was traced by a team of interviewers. Eligible nonresponders were asked several questions from the postal questionnaire, and their reason for not participating in the postal survey. RESULTS: Only 1% of those not responding were not traced in person or accounted for, and 12% were identified as not eligible to be in the survey sample (moved from address, deceased, residential home). Half of the eligible nonresponders (51%) did not answer the interviewer's questions, the main reason being general unwillingness or disinterest. The number in whom poor health was the reason increased with age. Comparing nonresponders who answered the interviewer's questions with a random sample of responders from the postal survey showed little difference in the reporting of urinary symptoms, although there were differences in general health and long-term health problems. Separate analyses by age showed greater reporting of some urinary symptoms and of poorer general health in the older nonresponders (>or= 70 years). CONCLUSION: Overall, for people aged >or= 40 years there was no evidence of a nonresponse bias in the reporting of urinary symptoms, providing confidence in such prevalence rates. However, poorer general health and greater reporting of some urinary symptoms by the older nonresponders (>or= 70 years) suggests prevalence rates in this age group may be underestimated.

The association of diet and other lifestyle factors with overactive bladder and stress incontinence: a longitudinal study in women.
Journal - BJU international (England )
OBJECTIVES: To investigate the role of diet and other lifestyle factors in the incidence of overactive bladder and stress incontinence in women. Studies have suggested relationships between different aspects of lifestyle and symptoms of urinary incontinence, but there is a lack of firm evidence about their role in its cause. SUBJECTS AND METHODS: A random sample of women aged >or= 40 years living at home took part in a prospective cohort study. Baseline data on urinary symptoms, diet and lifestyle were collected from 7046 women using a postal survey and food-frequency questionnaire. Follow-up data on urinary symptoms were collected from 6424 of the women in a postal survey 1 year later. Logistic regression was used to investigate the association of food and drink consumption and other lifestyle factors with the incidence of overactive bladder and stress incontinence. RESULTS: In the multivariate model for the onset of an overactive bladder, there were significantly increased risks associated with obesity, smoking and consumption of carbonated drinks, and reduced risks with higher consumption of vegetables, bread and chicken. Obesity and carbonated drinks were also significant risk factors for the onset of stress incontinence, while consumption of bread was associated with a reduced risk. CONCLUSIONS: Causal associations with obesity, smoking and carbonated drinks are confirmed for bladder disorders associated with incontinence, and additional associations with diet are suggested. Behavioural modification of lifestyle may be important for preventing and treating these disorders.
