Patellofemoral pain syndrome in children and adolescents: A cross-sectional study.

OBJECTIVES: To assess the prevalence and associated factors of Patellofemoral Pain Syndrome (PFPS) in children and adolescents. METHOD: A population-based cross-sectional study was conducted with children and adolescents aged 10 to 18 years, who presented a history of peripatellar and/or retropatellar pain, attending elementary or high school in urban public schools in Natal, Brazil. The sample size was calculated based on a minimum outcome prevalence of 22%. RESULTS: A prevalence of 24.7% of PFPS was found. There was a positive association of PFPS with active students (p < 0.01; PR: 2.5; CI: 1.4-4.5), low functional capacity (p < 0.01; PR: 8.0; CI: 5.0-12.8), and those classified as pubertal (p < 0.03; PR: 1.8; CI: 1.0-3.2). CONCLUSION: There was a considerable prevalence of PFPS in children and adolescents, as well as an association between the level of sexual maturation and adjustable determinants, such as the level of physical activity and low functional capacity in this group.

Biopsychosocial inequality, active lifestyle and chronic health conditions: a cross-sectional National Health Survey 2013 in Brazil.

This study estimated the biopsychosocial factors related to active physical behavior in the Brazilian population with and without chronic non-transmissible disease (NCD). Cross-sectional study of the National Health Survey (NHS) in Brazil, with 60,202 individuals in 2013. Participants were randomly selected by complex sampling. The outcome was physically active behavior measured by performing a minimum of 150 min of physical exercise per week. The independent variables were social and psychological characteristics, lifestyle and health. Cox regression was applied to estimate the prevalence ratio (PR). There are 29,666 (48.3%; 95% CI 47.0-50.0) participants reported having NCD. Not being a smoker or alcoholic, living in an urban area (PR = 1.44; CI95% 1.23-1.68/PR = 1.38; CI95% 1.08-1.75), having informal social support (PR = 1.26; CI95% 1.10-1.44/PR = 1.19; CI95% 1.05-1.34), A social class (PR = 0.43; CI95% 0.25-0.73/PR = 0.46; CI95% 0.26-0.80), high schooling (PR = 0.34; CI95% 0.23-0.51/PR = 0.33; CI95% 0.24-0.46) as well as paid work (PR = 0.87; CI95% 0.78-0.96/PR = 0.89; CI95% 0.79-0.99) are more associated with active lifestyle in both groups. However, only in the group without NCD, the male sex (PR = 1.42; CI95% 1.28-1.57), no having some disability (PR = 1.31; CI95% 1.03-1.66) and having private health insurance (PR = 1.26; CI95% 1.13-1.41) were more associated with active behavior, while in the group with NCD, being elderly (PR = 1.22; CI95% 1.05-1.42), not be white (PR = 0.85; CI95% 0.77-0.95) and not having restful sleep (PR = 1.23; CI95% 1.08-1.40) are associated with active lifestyle. People with and without NCD in Brazil have very close active behavior, however, some biopsychosocial factors such as: sex, age, lifestyle, socioeconomic level are unevenly associated with the active lifestyle in the groups. Thus, therapeutic or preventive proposals as well as public policies for health promotion must observe these distinctions when elaborating their actions.

Urinary Incontinence in Physically Active Older Women of Northeast Brazil.

Low- and moderate-impact physical activity (PA) is associated with the prevention of urinary incontinence (UI). The objective of the cross-sectional study presented herein is to analyze the factors associated with UI in physically older active women who participate in senior community groups. The variable UI was measured by the International Consultation Incontinence Questionnaire Short Form (ICIQ-SF). Socioeconomic variables were also collected, along with data on life habits and clinical history. The multivariate analysis employed Poisson's Regression with robust variance for factors associated with UI. Of the 106 participants evaluated, 54.7% presented UI, of which stress incontinence was more frequent, with 40.6%. UI presented a statistically significant association with dizziness/loss of balance during Activities of Daily Living (ADL) (prevalence ratio-PR 1.48; 95% CI 1.06-2.07) and nocturia (PR 1.63; 95% CI 1.05-2.55). Despite PA being a protection factor, UI presented an elevated prevalence in the older population, and therefore, other biological, social, and cultural aspects could also contribute to the occurrence of UI in this age group. Moreover, physically active older women with UI presented nocturia and dizziness/loss of balance during ADL, regardless of education levels and the number of births. These findings can help improve multi-professional programs aimed at promoting, preventing, and managing UI in the public.

Validade e acurácia do Guedes Tool para avaliar o apoio social informal para idosos / Validity and accuracy of the Guedes Tool for the evaluation of informal social support for older adults

Resumo Os objetivos foram confirmar a validade do Guedes Tool, instrumento para avaliação do apoio social informal (ASI) para idosos, e estimar sua acurácia. Foi realizada análise fatorial confirmatória (AFC) com avaliação dos índices CFI, RMSEA e relação do qui-quadrado (X2) com graus de liberdade (gl). Para análise de acurácia foi verificada a área sob a curva ROC, valores de sensibilidade (S), especificidade (E), valor preditivo positivo (VP+), valor preditivo negativo (VP-) e o Índice J de Younder (J) para confirmar o melhor ponto de corte. A coleta de dados ocorreu com idosos de Natal e região metropolitana em 2018. Os critérios de inclusão foram: ter 60 anos ou mais, com níveis cognitivos preservados. Duzentos e seis idosos participaram do estudo de AFC e 197 participaram da análise de acurácia. As estimativas dos índices avaliados na AFC foram: X2/gl=1,33, RMSEA=0,04 (IC95% 0,025-0,054) e CFI=0,91. A curva ROC obteve área de 0,78 (IC95: 0,72-0,85; p<0,001) para a determinação de idosos com baixo ASI. O J de maior valor foi de 0,44 para pontuação ≤34, o qual tem uma S de 59,76% e E de 84,96%. O instrumento apresentou um modelo bem ajustado com quatro dimensões, segundo critérios da AFC. Apresentou boa área sob a curva ROC e boa E e S moderada para o valor de corte de 34 pontos ou menos para o diagnóstico do ASI insuficiente. Os bons indicadores de VP+ e VP- reforçaram sua acurácia desejável.

Abstract The objective of the present study was to confirm the validity of the Guedes Tool, an instrument for assessing informal social support (ISS) for older adults, and to estimate its accuracy. Confirmatory factor analysis (CFA) was performed with the CFI and RMSEA indexes and the chi-square relationship (X2) with degrees of freedom (gl). For the analysis of accuracy, the area under the ROC curve, sensitivity ​​(S) and specificity (SP) values, positive predictive value (PV+), negative predictive value (PV-) and the Younder's J Index (J) were verified to confirm the best cut-off point. Data collection was carried out with older adults from Natal and metropolitan region in 2018. The inclusion criteria were: be 60 years old or older, with preserved cognitive levels. Two hundred and six older adults participated in the CFA study and 197 participated in the accuracy analysis. The estimates of the indexes evaluated in the CFA were: X2/gl =1.33, RMSEA=0.04 (95% CI 0.025-0.054) and CFI=0.91. The ROC curve obtained an area of ​​0.78 (CI95: 0.72-0.85; p<0.001) for the determination of older adults with low ISS. The highest value J was 0.44 for a score ≤34, with an S value of 59.76% and an SP value of 84.96%. The instrument presented a well-adjusted model with four dimensions, according to CFA criteria. It had a good area under the ROC curve and good to moderate S and SP values for the cutoff value of 34 points or less, for the diagnosis of insufficient ISS. Good PV+ and PV- indicators confirmed the desirable levels of accuracy of the tool.

Body Image of Women Submitted to Breast Cancer Treatment

Background: The study of body image includes the perception of women regarding the physical appearance of their own body. The objective of the present study was to verify the prevalence of body image dissatisfaction and its associated factors in women submitted to breast cancer treatment. Methods: A cross-sectional study carried out with 103 female residents of the municipality of Natal (Northeast Brazil), diagnosed with breast cancer who had undergone cancer treatment for at least 12 months prior to the study, and remained under clinical monitoring. The variable body image was measured through the validated Body Image Scale (BIS). Socioeconomic variables and clinical history were also collected through an individual interview with each participant. The Pearson's chi-squared test (Fisher's Exact) was utilized for bivariate analysis, calculating the prevalence ratio with 95% confidence interval. Poisson regression with robust variance was utilized for multivariate analysis. The statistical significance considered was 0.05. Results: The prevalence of body image dissatisfaction was 74.8% CI (65%-82%). Statistically significant associations were observed between body image and multi-professional follow-up (p=0.009) and return to employment after treatment (p=0.022). Conclusion: It was concluded that women who reported employment after cancer treatment presented more alterations in self-perception concerning their appearance. Patients who did not receive multi-professional follow-up reported negative body image, evidencing the need for strategies that increase and improve healthcare, aiming to meet the demands of this population.

Functional Disability in Women Submitted to Breast Cancer Treatment

The objective of the study presented herein was to verify the prevalence of functional disability and its associated factors in women submitted to breast cancer treatment. A cross-sectional study was carried out, in 101 women diagnosed with malignant breast cancer neoplasm, who underwent cancer treatment at least 12 months before the study, and remained under clinical monitoring. Functional disability was measured by the DASH instrument. Data collection included variables related to socioeconomic characteristics, life habits, health conditions, clinical tumor characteristics and therapeutic approach. Bivariate analysis was carried out by Pearson's chi-square test or Fisher's exact test, calculating the prevalence ratio with a 95% confidence interval. Multivariate analysis utilized Poisson's Regression with robust variance. A statistical significance of 0.05 was considered. Prevalence of functional disability in the studied sample was 22.8% (CI95% 13.9-31.6). Functional disability was statistically significantly associated with age (p = 0.035) and access to health services (p = 0.028). It was concluded that younger patients suffered higher impact of breast cancer treatment on disability. Regarding access to health services, women that received public clinical monitoring reported higher occurrences of functional disability. This pointed towards the necessity of more organized, less bureaucratic, and effective health services in the assistance network, directed to the minimization of the impacts of cancer treatment on health and life conditions of breast cancer survivors.

Validation of the two minute step test for diagnosis of the functional capacity of hypertensive elderly persons / Validação do teste de marcha estacionária de dois minutos para diagnóstico da capacidade funcional em idosos hipertensos

Objectives : To analyze the accuracy of the 2 minute step test in the diagnosis of the normal functional capacity (FC) of hypertensive elderly individuals or hypertensive elderly individuals with other associated chronic conditions (ACC). Methods : An observational diagnosis type study of 101 subjects, 41 of whom were hypertensive and 60 of whom were normotensive, was carried out. Receiver Operating Characteristic curves (ROC) were constructed based on the normal FC variable. Results : For hypertensive patients, the 2MST, with an under the ROC curve area of 0.7 (95% CI: 0.50 to 0.87, p = 0.04), proved to be accurate at diagnosing FC. Among hypertensive individuals with an elevation of 69, sensitivity of 80% and specificity of 54% were observed. The 2MST was accurate at predicting normal FC among hypertensive patients with ACC, with an under the ROC curve area of 0.88 (95% CI: 0.69 to 1.00, p= 0.02). With an elevation of 65 the sensitivity was 83% and the specificity was 67%. Conclusions : The 2MST revealed good sensitivity and specificity when assessing the FC of elderly hypertensive individuals and elderly hypertensive patients with ACC, which was not the case among normotensive elderly persons.
