ICIQ symptom and quality of life instruments measure clinically relevant improvements in women with stress urinary incontinence.

AIMS: To determine whether changes in questionnaire scores on symptoms and condition-specific quality of life reflect clinically relevant improvements in women with stress urinary incontinence (SUI). METHODS: We retrospectively analyzed questionnaires collected during a randomized controlled trial in women with SUI, that received pelvic floor muscle training (PFMT) in two different formats. We included 218 women that answered validated self-assessment questionnaires at baseline and at a 4-month follow-up. We registered changes on two questionnaires, the International Consultation on Incontinence Modular Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) and the Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol). We compared these score changes to responses from the Patient Global Impression of Improvement (PGI-I) questionnaire. Differences were analyzed with the Spearman rho and one-way-ANOVA. The minimum important difference (MID) was the mean change in score for women that experienced a small improvement. RESULTS: The PGI-I correlated significantly to both the ICIQ-UI SF (r = 0.547, P < 0.0001) and ICIQ-LUTSqol (r = 0.520, P < 0.0001). Thus, larger reductions in symptoms or quality of life scores were associated with greater impressions of improvement. The changes in ICIQ-UI SF and ICIQ-LUTSqol scores were significant across all PGI-I groups from "no change" to "very much improved" (P < 0.05). The MIDs were 2.52 (SD 2.56) for ICIQ-UI SF and 3.71 (SD 4.95) for ICIQ-LUTSqol. CONCLUSIONS: The change in ICIQ-UI SF and ICIQ-LUTSqol scores after PFMT reflected clinically relevant improvements in women with SUI. The MIDs established for this population may facilitate future research, treatment evaluations, and comparisons between studies.

AN INCREASE IN RISK FACTORS FOR CARDIOVASCULAR DISEASE IN YOGYAKARTA, INDONESIA: A COMPARISON OF TWO CROSS-SECTIONAL SURVEYS.

This paper aims to describe changes in risk factors for cardiovascular disease (CVD) over a five year period in urban Indonesia. In 2004 (n = 3,205) and 2009 (n = 2,467) we conducted cross-sectional surveys of residents in Yogjakarta City, Indonesia evaluating risk factors for CVD. Smoking habits, fruit and vegetable intake, physical activity, blood pressure, weight, and height were recorded. The results of these 2 surveys conducted 5 years apart were then compared. The risk for having a CVD event was also calculated. Behavioral CVD risk factors were more common among men. The predicted risk of having a CVD event increased from 8.4% to 11.3% among men between 2004 and 2009. Effective measures need to be taken to change these behaviors among men in Yogyakarta, Indonesia.

Stress urinary incontinence and quality of life: a reliability study of a condition-specific instrument in paper and web-based versions.

AIMS: Quality of life is an important outcome measure in studies of urinary incontinence. Electronic collection of data has several advantages. We examined the reliability of the Swedish version of the highly recommended condition-specific quality of life questionnaire International Consultation on Incontinence Modular Questionnaire-Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol), in paper and web-based formats in women with stress urinary incontinence. METHODS: Women aged 18-70 years, with stress urinary incontinence at least once weekly, were recruited via the project's website and answered the ICIQ-LUTSqol questionnaire. Respondents completed either the paper version twice (n = 78), or paper and web-based versions once each (n = 54). The ICIQ validation protocol was followed. RESULTS: The mean interval between answers was 18.1 (SD = 3.1) days in the paper versus paper setting and 15.0 (SD = 7.8) days in the paper versus web-based setting. Internal consistency was excellent, with Cronbach's alpha coefficients of 0.87 for the paper version and 0.86 for the web-based version. There was a high degree of agreement of overall scores with intraclass correlations in the paper versus paper and paper versus web-based settings: 0.95 (P < 0.001) and 0.92 (P < 0.001), respectively. The mean of each individual item's weighted kappa value was 0.61 in both settings. CONCLUSIONS: The questionnaire is reliable in women with stress urinary incontinence, and it can be used in either a paper or a web-based version.

Anal sphincter electromyography in patients with newly diagnosed idiopathic parkinsonism.

OBJECTIVES: The differential diagnosis of patients with idiopathic parkinsonism is difficult, especially early in the course of the disease. External anal sphincter electromyography (EAS-EMG) has been reported to be of value in the differential diagnosis between Parkinson's disease (PD) and multiple system atrophy (MSA). Patients with MSA are reported to have pathological EAS-EMG and patients with PD are reported to have significantly less pathological EAS-EMG results. Comparisons between patients with parkinsonian disorders have usually been made many years into the disease, and thus it is largely unknown if the results of EAS-EMG can be used to distinguish the different diagnoses in the early phase of the disease. MATERIALS AND METHODS: We investigated 148 newly diagnosed patients with idiopathic parkinsonism from a population-based incidence cohort (100 definite PD, 21 probable PD, 16 MSA, 11 progressive supranuclear palsy, and 40 controls) with EAS-EMG within 3 months of their first visit and, in the majority of patients, before start of treatment with dopaminergic drugs. The clinical diagnoses were made using established clinical diagnostic criteria after a median follow-up of 3 years. RESULTS: All patient groups had more pathological EAS-EMG results than controls. No EAS-EMG differences were found between the patient groups, especially not between PD and MSA. CONCLUSIONS: External anal sphincter electromyography examination cannot separate the different parkinsonian subgroups from each other in early course of the diseases.

Mechanisms for the social gradient in health: results from a 14-year follow-up of the Northern Swedish Cohort.

OBJECTIVE: Although numerous studies have demonstrated a socio-economic gradient in health, there is still a lack of research about the mechanisms behind this gradient. The aim of this study was to analyse possible mechanisms from adolescence to adulthood to explain the socio-economic gradient in somatic symptoms among men and women in the Northern Swedish Cohort. STUDY DESIGN: A prospective cohort study was performed, in which all pupils (n = 1083) in the last year of compulsory school were followed for 14 years. The response rate was high, with 96.6% still participating after 14 years. The data were mainly collected through repeated comprehensive self-administered questionnaires. METHODS: The main dependent variable was a combination of socio-economic position and somatic health at 30 years of age. Multivariate multinomial and bivariate logistic regression analyses were undertaken. RESULTS: After controlling for parental working-class position and health-related selection, the authors identified mechanisms from adolescence to adulthood for the socio-economic gradient in health that were related to social relations (poor relationship with father and unemployed friends among men, violence among women), labour market experiences (unemployment among men and women, physically heavy work among women), economic hardship (among women) and poor health behaviour. CONCLUSION: These analyses contribute to the development of epidemiological methods for analysing mechanisms for the socio-economic gradient in health.

Cognitive function in early Parkinson's disease: a population-based study.

BACKGROUND AND PURPOSE: The study aims to describe the frequency, pattern and determinants of cognitive function in patients with newly diagnosed Parkinson's disease (PD); to compare patients with impaired cognition to patients with intact cognition; and to compare to matched healthy controls. METHODS: Patients were identified in a longitudinal population based study of idiopathic non-drug induced parkinsonism. Eighty-eight newly diagnosed patients with PD and no dementia were included during a four year period. The patients and 30 age- and sex-matched healthy control subjects underwent a comprehensive neuropsychological assessment. RESULTS: Patients performed significantly worse than healthy controls in a majority of neuropsychological tests. Test results in attention, psychomotor function, episodic memory (free recall), executive function and category fluency were significantly lower in the patient group. Comparison with normative data revealed that 30% of the patients had deficits in > or =1 cognitive domain (episodic memory, executive function and verbal function). Seventy per cent of the patients had normal performance. Unified Parkinson's Disease Rating Scale (UPDRS) III sub scores; speech, facial expression, rigidity and bradykinesia were significantly higher, and disease duration shorter amongst the cognitively impaired than amongst the cognitively intact patients. Tremor showed no difference. Education level was an independent predictor of dysfunction in patients with > or =2 cognitive domains affected. CONCLUSION: Cognitive dysfunction is common in untreated patients in early PD, affecting attention, psychomotor function, episodic memory, executive function and category fluency. Education level was an independent predictor of severe cognitive dysfunction.

Fracture mechanisms and fracture pattern in men and women aged 50 years and older: a study of a 12-year population-based injury register, Umeå, Sweden.

UNLABELLED: In a study of a 12-year population-based injury register, Umeå, Sweden, we analyzed the fracture mechanisms and fracture pattern in men and women 50 years and older. Low-energy trauma was responsible for the major and costliest part of the fracture panorama, but the pattern differs between age groups. INTRODUCTION: Osteoporosis-related fracture is a major health problem: the number of hip fractures is expected to double to 2030. While osteoporosis is one of many risk factors, trauma is almost always involved. Therefore, we analyzed injury mechanisms in patients aged over 50. METHODS: We registered injury mechanism, cause, diagnosis in all trauma patients at Umeå University hospital, Sweden. This population-based register (1993-2004) comprises a total of 113,668 injuries (29,189 fractures). Patients >or=50 years contributed to 13,279 fractures. RESULTS: Low-energy trauma (fall <1 m) caused 53% of all fractures >or=50 years and older. In those over 75 low-energy trauma caused >80%. The seasonal variation of fractures was maximally 25%. With increasing age, proximal fractures became more common, in both upper and lower extremities. Proximal locations predominate in older age groups. CONCLUSIONS: Low-energy trauma was responsible for the largest and costliest part of the fracture panorama. In fact, almost all fractures in middle-aged and old people were caused by low-energy mechanisms; thus, most fractures in these patients have a fragility component, and the contribution of osteoporosis-related fractures is more important than previously thought. A better understanding of injury mechanisms also in low-energy trauma is a prerequisite for preventive interventions.

Work stress and low emotional support is associated with increased risk of future type 2 diabetes in women.

A case-referent study nested within a population-based health survey investigated the associations between psychosocial stress, such as work stress and low emotional support, and future development of type 2 diabetes among occupationally working middle-aged men and women. All participants in a health survey conducted during 1989-2000 (n=33,336) in Umeå in northern Sweden, were included. We identified 191 cases, who were not diabetic initially but were diagnosed with type 2 diabetes after 5.4+/-2.6 years. Two age- and sex-matched referents were selected for each case. Multivariate logistic regression analyses and interaction effects between variables were evaluated. In women, passive or tense working situations were associated with future type 2 diabetes with odds ratios 3.6 (95% confidence interval 1.1-11.7) and 3.6 (1.0-13.3), respectively, and also low emotional support 3.0 (1.3-7.0). These associations were not seen in men. In women, they remained after adjustment for BMI, civil status and educational level, and there were also tendencies for interactions between work stress and low emotional support. In conclusion, work stress and low emotional support may increase the risk of type 2 diabetes in women, but not in men. These findings contribute to our understanding of psychosocial stress as potential risk factors for type 2 diabetes in a Swedish population.

Nurse-led patient-centered self-management support improves HbA1c in patients with type 2 diabetes-A randomized study.

OBJECTIVES: The aim of this study was to evaluate the effect of a patient-centered self-management support, in type 2 diabetes (T2D) with regard to metabolic changes. METHODS: 182 patients were randomized into group intervention (GI), individual intervention (II) or internal controls (IC). An external control (EC) group was recruited from another county council. The intervention consisted of six sessions that featured themes, which regarded different views of their illness experiences. Data were collected in 2010 and 2011. RESULTS: HbA1c was significantly decreased at 12-month follow-up with 5mmol/mol in the GI and 4mmol/mol in the II. In the IC group, the HbA1c was close to baseline. The EC group had increased HbA1c, though not significantly. When the HbA1c difference at baseline was adjusted, there was a significant difference between intervention groups and the EC-group. CONCLUSION: Patient-centered self-management support, led by nurses, can lower HbA1c among patients with type 2 diabetes. PRACTICE IMPLICATIONS: It is possible to train diabetes specialist nurses in clinical patient-centered care, and simultaneously influence patients' metabolic balance positively.

Mandibular advancement device in patients with obstructive sleep apnea : long-term effects on apnea and sleep.

STUDY OBJECTIVES: To evaluate the long-term effects on apneas and sleep and the tolerability of a mandibular advancement device in patients with obstructive sleep apnea. DESIGN: Prospective study. SETTING: Department of Respiratory Medicine, University Hospital, Umeå, Sweden. PATIENTS: Thirty-three consecutively treated patients. INTERVENTIONS: Individually adjusted mandibular advancement devices. MEASUREMENTS AND RESULTS: Polysomnographic sleep recordings on 1 night without the device and 1 night with the device were performed after 0.7 +/- 0.5 years (mean +/- SD) and after 5.2 +/- 0.4 years from the start of treatment. Nineteen of the 33 patients experienced a short-term satisfactory treatment result with an apnea-hypopnea index of < 10 events per hour and a satisfactory reduction in snoring. Fourteen patients were regarded as being insufficiently treated with the device. Seventeen of the short-term satisfactorily treated patients (90%) and 2 of the remaining patients continued treatment on a long-term basis. The apnea-hypopnea index was reduced by the device from 22 +/- 17 to 4.9 +/- 5.1 events per hour (p < 0.001) in these 19 long-term treatment patients, which did not differ from what was found at the short-term follow-up visits in these patients. Patients with their devices replaced or adjusted experienced a better long-term effect than patients still using their original devices (p < 0.05). CONCLUSIONS: The long-term effect and tolerability of a mandibular advancement device are good in patients who are recommended the treatment on the basis of a short-term sleep recording, provided that the device is continuously adjusted or replaced with a new one when needed. A short-term follow-up is valuable in the selection of patients who will benefit from long-term treatment with a mandibular advancement device.

Snoring, pregnancy-induced hypertension, and growth retardation of the fetus.

STUDY OBJECTIVE: Our purpose was to study the relationship between snoring and pregnancy-induced hypertension and growth retardation of the fetus. DESIGN: Retrospective, cross-sectional, consecutive case series. SETTING: The Department of Gynecology and Obstetrics, University Hospital, Umeâ, Sweden. PARTICIPANTS AND MEASUREMENTS: On the day of delivery, 502 women with singleton pregnancies completed a questionnaire about snoring, witnessed sleep apneas, and daytime fatigue. Data concerning medical complications were taken from the women's casebooks. RESULTS: During the last week of pregnancy, 23% of the women reported snoring every night. Only 4% reported snoring before becoming pregnant. Hypertension developed in 14% of snoring women, compared with 6% of nonsnorers (p < 0.01). Preeclampsia occurred in 10% of snorers, compared with 4% of nonsnorers (p < 0.05). An Apgar score < or = 7 was more common in infants born to habitual snorers. Growth retardation of the fetus, defined as small for gestational age at birth, had occurred in 7.1% of the infants of snoring mothers and 2.6% of the remaining infants (p < 0.05). Habitual snoring was independently predictive of hypertension (odds ratio [OR], 2.03; p < 0.05) and growth retardation (OR, 3.45; p < 0.01) in a logistic regression analysis controlling for weight, age, and smoking. CONCLUSIONS: Snoring is common in pregnancy and is a sign of pregnancy-induced hypertension. Snoring indicates a risk of growth retardation of the fetus.

Recurrence of prolonged pregnancy.

BACKGROUND: We conducted a cohort study in an attempt to determine whether prolonged pregnancy in mother is a risk factor for prolonged pregnancy in daughter, and if previous prolonged pregnancy is a risk factor for prolonged pregnancy in subsequent pregnancy. METHODS: Data from the Swedish Medical Birth Registry were combined with a local registry of births (1955-1990). Mother-daughter pairs (with events of delivery in each generation) were identified. Relative risk (RR) and its 95% confidence interval (CI) were calculated and population attributable proportion was estimated when appropriate. RESULTS: If mother had had prolonged pregnancy at delivery of daughter the relative risk (RR) of prolonged pregnancy in daughter was moderately raised (RR = 1.3; CI : 1.0-1.7) with population attributable proportions ranging between 2.1% and 4.6%. If previous pregnancy had been prolonged, the RR of prolonged pregnancy at subsequent birth was increased 2-3 fold with population attributable proportions of 12.5% to 15.8%. Possible confounders such as mother's parity, age and maternal age did not alter the risks. CONCLUSIONS: Although moderate, prolonged pregnancy in mother may be a risk factor for prolonged pregnancy in daughter. A previous prolonged pregnancy increases the risk of prolonged pregnancy in a subsequent birth. However, the familial factor of prolonged pregnancy explains just a minor part of its occurrence in the population (due to small population attributable proportions).

Fetal exposure, heredity and risk indicators for cardiovascular disease in a Swedish welfare cohort.

BACKGROUND: The overall aim was to test whether low birthweight (LBW) in newborns is associated with the risk indicators for cardiovascular disease in early middle age, even in a welfare society. Further, a possible interaction of LBW and heredity for myocardial infarction or stroke was investigated. METHODS: Overall, subjects were identified as newborns in a local birth register, and as adult participants, in the Västerbotten Intervention Program (n = 7876). Outcome measures such as systolic (SBP) and diastolic blood pressures (DBP), body mass index (BMI), cholesterol, triglycerides and anthropometrics were investigated (at age 29-41 years) in relation to LBW. RESULTS: Low birthweight was associated with increased SBP and DBP. Triglycerides were elevated among women with LBW and total cholesterol was elevated in men with LBW. Heredity for myocardial infarction or stroke interacted with LBW, and indicated a synergistic effect on the level of SBP. The BMI did not differ between LBW and normal birthweight subjects. CONCLUSIONS: Our interpretation is that the 'fetal origins' hypothesis' is valid for middle-age subjects who grow up in a welfare society. The population attributable proportions that result from different exposures to LBW were relatively small overall; from a public health perspective, heredity was more important than LBW for elevated SBP.

Caries rates related to approximal caries at ages 11-13: a 10-year follow-up study in Sweden.

Predicting future caries risk is a difficult but important clinical task. The aim of this study was to analyze radiographically the relationship between approximal caries (4d-7m) at ages 11-13 (baseline) and future approximal caries. We followed 534 individuals prospectively through annual bitewing radiographs from 11 to 22 years of age. Two measures were used: individual-based incidence of the first new approximal caries lesion and surface-based incidence of approximal lesions. In the group with no approximal caries lesions at baseline, the individual-based incidence was 19 first new approximal lesions/100 person-years; the corresponding value for those with 3 approximal lesions at baseline was 71. Individuals with no approximal lesions at baseline developed 3.1 new lesions/100 tooth surface-years; the corresponding value for those with 3 lesions at baseline was 7.7. The highest risk for developing new approximal lesions was within the first 2 years after baseline.

Women's strategic responses to violence in Nicaragua.

STUDY OBJECTIVE: To describe the responses of women in León, Nicaragua to partner abuse and identify contextual factors associated with the use of certain coping mechanisms and the likelihood of permanent separation. DESIGN: Cross sectional population-based survey. SETTING: León, Nicaragua. PARTICIPANTS: 188 women 15-49 years of age who had experienced physical partner abuse, out of 488 women interviewed. MAIN RESULTS: 66% of women defended themselves effectively from abuse either physically or verbally. Forty one per cent of women had left home temporarily because of violence and 20% had sought help outside the home. Women experiencing severe abuse were more likely to leave or seek help, whereas women with less severe abuse were more able to defend themselves effectively. Seventy per cent of women eventually left abusive relationships. Help seeking and temporary separations increased the likelihood of a permanent separation, whereas women who defended themselves and were able to stop the violence, at least temporarily, were more likely to remain in abusive relationships. CONCLUSIONS: Women in Nicaragua use a variety of methods in order to overcome physical partner abuse. Temporary leaving and help seeking are critical steps in the process of leaving a violent relationship. However, many women indicated that they did not receive support for their situation. More interventions are needed to help women recognise and deal with violence, as well as strengthening the community support networks available to abused women.

Oral health behaviour and self-esteem in Swedish children.

This study focus on the socio-psychological concept of self-esteem and examines its association with oral health behaviour and with some background variables that have been shown to be of importance in previous studies. In 1995, 3370 12-year-olds answered a questionnaire on social and demographic factors. Questions on attitudes and behaviour were also included. After reducing the number of variables and constructing new variables, multivariate analyses were performed. A polytomous regression on self-esteem showed that having very poor self-esteem as opposed to poor, good and very good self-esteem was associated with being a girl, not living with one's biological parents, poor social support, having less interest in politics, poor adaptation in school and poor oral health behaviour. The results also showed that being a boy, choosing statements reflecting less exemplary behaviour, and being less well adapted in school increased the risk of having poor oral health behaviour, as did ethnic group affiliation and having poor self-esteem. Our results showed that self-esteem is a crucial intervening variable between variables measuring social background and outcome variables, especially oral health behaviour.

Nutrient intake and iron status of urban poor and rural poor without access to rice fields are affected by the emerging economic crisis: the case of pregnant Indonesian women.

OBJECTIVE: We evaluated the adequacy of nutrient intake in comparison with the Indonesian Estimated Average Requirement (EARs) among pregnant Indonesian women and explain the short-term effect of economic crisis on nutrient intake and iron status. DESIGN: Cross-sectional study. SETTING: Purworejo District, Central Java, located 60 km west of Yogyakarta Province, Indonesia. SUBJECTS: During the period from 1996 to 1998, up to six 24 h recalls were performed during the second trimester of pregnancy among 450 women. Nutrient intake and iron status was evaluated in relation to date of data collection relative to the economic crisis that emerged in August 1997. A computer program (Inafood) was developed to calculate nutrient intake. RESULTS: : Forty percent of the pregnant women were at risk of inadequate intake of energy and protein, and 70% were at risk of inadequate intake of vitamin A, calcium and iron even before the crisis. Our results also demonstrate an effect of short-term economic crisis on nutrient intake and iron status. When the crisis emerged, urban poor experienced a decrease in intake of most nutrients. During the crisis, rich women experienced a significant decrease in fat (P<0.05). Negative changes in fat density during crisis were experienced by the rich and the rural, poor, and access to rice field subgroups (P<0.01). A significant increase in carbohydrate densities was seen for the rich and rural, poor, and access to rice fields groups (P<0.05). Urban poor experienced decreased serum ferritin concentration (P<0.05), whereas rich women experienced a significant increase (P<0.05). CONCLUSIONS: Urban poor and rural poor landless women were most directly affected by the emerging economic crisis.

The effect of smelter work on fecundity.

Time to pregnancy (TTP) has been proposed as a screening instrument for the detection of environmental and occupational hazards to reproduction. Our aim was to determine whether reduced fecundity could be found among smelter workers and couples living near the smelter. The number of Months required to achieve a pregnancy was determined via a questionnaire, and TTP was analyzed using a logistic regression model with a cutoff at 12 months. No significant findings were found for a risk of having to wait for more than 12 months to achieve pregnancy because of occupational or environmental exposure. It could be that the exposure variables tested were not sensitive enough in detecting hazards to reproduction or that they were of minor importance. A tendency toward a prolonged TTP was found for couple living near the smelter.

Assessment of body perception among Swedish adolescents and young adults.

PURPOSE: To assess body perception in adolescents and young adults without anorexia nervosa. METHOD: Using a visual size estimation technique, perceived body size was estimated in four groups of Swedish adolescents and young adults without anorexia nervosa (86 males and 95 females). Perceived body size was estimated at nine different body sites comparing these estimations to real body size. RESULTS: The results show that 95% of males and 96% of females overestimated their body size (mean overestimation: males +22%, females +33%). The overestimations were greatest in females. The greatest overestimations were made of the waist (males +31%, females +46%), buttocks (males +22%, females +42%), and thighs (males +27%, females +41%). CONCLUSIONS: The results indicate that overestimation of body size may be a general phenomenon in adolescents and young adults in a country such as Sweden, implying a similar, but less pronounced distortion of body image as in individuals with anorexia nervosa.

Energy intake during economic crisis depends on initial wealth and access to rice fields: the case of pregnant Indonesian women.

Starting in August 1997, Indonesia experienced a radical and rapid deterioration in its economy. Between 1996 and 1998, dietary intake during the second trimester was measured in 450 pregnant women in Purworejo, Central Java, Indonesia. Using six 24 h recalls we describe the consequences of the economic crisis on the energy intake of pregnant Indonesian women. Depending on the date of data collection, women were grouped into 'before crisis', 'transition' and 'during crisis'. Mean energy intake among groups was compared using ANOVA and Student's t-test. All groups of pregnant women already had a mean energy intake before the emerging crisis that was lower than the Indonesian recommended dietary allowances (RDA). Nevertheless, energy intake differed significantly among women with different education levels (P = 0.00) and from different socio-economic groups (P = 0.00). 'During transition', a significant decrease in energy intake was experienced by urban poor women (P = 0.01). Poor women with access to rice fields had a higher rice consumption than other groups throughout the period. Our results most likely reflect the effect of higher rice price on income and welfare. 'During crisis', energy intake improved among vulnerable groups, perhaps reflecting government intervention.
