Validation of the "international consultation on incontinence questionnaire urinary incontinence quality of life" / Validación de la "consulta internacional sobre incontinenciacuestionario de incontinencia urinaria módulo de calidad de vida" / Validação do "international consultation on incontinence questionnaire urinary incontinence quality of life module"

ABSTRACT Objective: To Validate the International Consultation on Incontinence Questionnaire Quality of Life for the Portuguese population. Urinary incontinence is a highly prevalent condition with a negative impact on people's quality of life. The International Consultation on Incontinence Questionnaire Quality of Life was adapted in order to have a standardized structure that allows the assessment of the impact of urinary incontinence on quality of life. Method: An observational cross-sectional study was carried out with two hundred and twenty participants recruited at the Centro Hospitalar de Vila Nova de Gaia/Espinho and at the Centro Hospitalar Universitário de São João during the period from September 2019 to January 2020. The psychometric properties of the questionnaire were assessed. For internal consistency, the standardized Cronbach's alpha coefficient was calculated. In order to obtain construct validity, an exploratory factor analysis was performed using varimax rotation to extract the main components. Results: The Portuguese version of the questionnaire has 21 items distributed by the three factors found, maintaining the items proposed in the original version. The result of standardized Cronbach's alpha coefficient, α=0.906 overall, confirms the internal consistency of the Portuguese version of the instrument. Pearson's correlation analysis was performed between each item and the item assessing the impact on quality of life in the form of a scale, verifying a positive correlation in all items. Conclusions: The Portuguese version of the questionnaire proved to be reliable and valid in the study carried out for clinical and research use.

RESUMO Objetivo: Validar o International Consultationon Incontinence Questionnaire Quality of Life para a população portuguesa. A incontinência urinária é uma condição com elevada prevalência e com impacto negativo na qualidade de vida das pessoas. O International Consultationon Incontinence Questionnaire Quality of Life foi adaptado de forma a ter uma estrutura estandardizada e que permite avaliar o impacto da incontinência urinária na qualidade de vida. Método: Foi realizado um estudo observacional do tipo transversal com duzentos e vinte participantes recrutados no Centro Hospitalar de Vila Nova de Gaia/Espinho e no Centro Hospitalar Universitário de São João durante o período de setembro de 2019 a janeiro de 2020. Foram avaliadas as propriedades psicométricas do questionário. Para a consistência interna foi calculado o coeficiente alfa de Cronbach padronizado. Para obter a validade do constructo foi realizada uma análise exploratória fatorial por rotação varimax para extração dos principais componentes. Resultados: A versão portuguesa do questionário tem 21 itens distribuídos pelos três fatores encontrados mantendo, no entanto, os itens propostos na versão original.O resultado de coeficiente alfa de Cronbach padronizado, α=0,906 global, confirma a consistência interna da versão portuguesa do instrumento. Foi realizada a análise da correlação de Pearson entre cada item e o item de avaliação do impacto na qualidade de vida em forma de escala verificando-se uma correlação positiva em todos os itens. Conclusões: A versão portuguesa do questionário, mostrou-se confiável e válida no estudo realizado para utilização na clínica e na investigação.

Patterns of lifestyle-related behaviors and parents'overweight are associated with increased body adiposity in schoolchildren: a cross-sectional study in Portugal

BACKGROUND: This study evaluated the association between lifestyle-related behavior patterns and weight status indicators in schoolchildren. METHODS: Cross-sectional study includes nationally representative sample of Portuguese school children (6­9yearsold;n= 10,258). Weight status was assessed using the body mass index (BMI) and waist circumference (WC). Principal component analysis was used to identify lifestyle-related behavior patterns. Multiple linear regression models were used to estimate the association between behavior patterns, BMI, and WC.RESULTS: Six lifestyle-related behavior patterns were identified: pattern 1: consuming iced tea and soft drinks≥2 times/week, having a television (TV) in the bedroom, watching TV≥2 h/day, and consuming <2 portions of fruits/day; pattern 2: parents and children remaining physically inactive during leisure time; pattern 3: consuming≤1 portion of vegetables and milk/day; pattern 4: having parents with excess weight; pattern 5: consuming≤3daily meals and skipping breakfast; and pattern 6: not participating in physical education classes. After the adjustment, all of the patterns were associated with increased BMIz-score (P≤0.02) and WC (P≤0.03).CONCLUSIONS: Lifestyle-related behavior patterns were associated with an increased risk of excess weight and the central distribution of body fat. Taking a public health perspective toward preventing childhood obesity, special attention should be given to identify subgroups with simultaneous occurrence of multiple risk behaviors, which is useful for planning prevention programs.

Irregular breakfast habits are associated with children's increased adiposity and children's and parents' lifestyle-related behaviors: a population-based cross-sectional study

BACKGROUND: Skipping meals, especially breakfast, is related to an increase in adiposity indicators, and this behavior is related to metabolic changes that predispose to the development of chronic diseases, recognized as major causes of death worldwide. The objective of the present paper was estimated the association between irregular breakfast habits with adiposity indices in schoolchildren and other lifestyle factors. METHODS: A population-based cross-sectional study was conducted in 2009­2010, including schoolchildren (n=10,243) between 6 and 9 years old (51.3 % girls) from 18 districts of mainland Portugal. Breakfast habits were as certained by asking a yes/no question ("Does your child eat breakfast regularly?"). An index estimated by performing principal component analysis was used to assess body adiposity from three different adiposity indicators (body mass index (BMI), waist circumference (WC), and the triceps, subscapular, and supra iliac skinfolds (used to estimate body fat percentage (BFP))). Multivariate logistic regression and multiple linear regression models were used to estimate the association of irregular breakfast habits with anthropometric indicators (BMI, BMI z score, WC, BFP, and adiposity index) and with children's and parents' lifestyle and socioeconomic characteristics. RESULTS: A total of 3.5 % of the children did not have breakfast regularly (girls 3.9 %; boys 3.1 %; P= 0.02). Among boys, irregular breakfast habits were associated with lower fathers' education level, television time≥2 h/day, and soft drink consumption≥2 times/week. For girls, irregular breakfast habits were associated with lower mothers' education level and physical inactivity, soft drink consumption≥2 times/week, and <1 portion of milk/day. Multivariate linear models revealed a positive association between irregular breakfast habits with increased adiposity indicators among boys (BMI (kg/m2):ß= 1.33; BMI z score:ß= 0.48; WC (cm):ß= 2.00; BFP (%):ß= 2.20; adiposity index:ß= 0.37;P< 0.01 for all). No significant association was found for girls. CONCLUSIONS: Irregular breakfast habits were positively associated with boys' increased global adiposity and were significantly affected by children's and parents' lifestyle-related behaviors.
