Association between Diet and Adiposity in Adults: Influence of Sedentary Behavior Patterns.

This study analyzed the influence of sedentary behavior (SB) on the association between dietary patterns and adiposity in community-dwelling adults. Eight hundred and forty-three adults (age: 56.5 ± 18.3 years) participated in this cross-sectional epidemiological study. Dietary patterns were evaluated using self-report questions regarding the weekly frequency of consumption of certain foods. Adiposity was determined using anthropometric measurements of weight, waist circumference, and height. SB was evaluated according to the time spent on screen devices. The usual physical activity level and socioeconomic status were considered confounding factors. Associations were determined using multivariate linear models with simultaneous adjustments for confounding variables. A statistical analysis indicated that fruit consumption was negatively related to the body mass index, regardless of the adjustment for SB domains. Red meat consumption was positively related to the body mass index, and fried food consumption was positively related to the waist-to-height ratio, regardless of the adjustment for SB domains. The consumption of fried food was positively associated with global and central adiposity after the adjustments for confounding factors and time spent on screen devices. We concluded that dietary habits are related to adiposity in adults. However, SB domains seem to influence the relationship between body adiposity and dietary habits, mainly regarding the consumption of fried foods.

Association between Different Domains of Sedentary Behavior and Health-Related Quality of Life in Adults: A Longitudinal Study.

Extended periods of time on screen devices and sitting are the main activities that characterize sedentary behavior (SB), which negatively impacts the quality of life. This negative influence was demonstrated mainly by cross-sectional studies performed in high-income countries in which the effects of screen time on health-related quality of life (HRQoL) is not considered. Thus, we analyzed the association between the different domains of SB (i.e., subdomains of screen time-television, computer, cellphone) and the HRQoL in adults that live in Brazil during two years of follow-up. The sample included 331 adults. Subdomains of screen time (i.e., watching television, using computers, and cellphones) and of HRQoL (i.e., physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health, and current health perception) were assessed by a structured questionnaire and SF-36, respectively. Our results indicate a significant increase in screen time during the two years of follow-up. Linear regression models indicated that although domains of SB were differently associated with HRQoL, in general, screen time was negatively associated with social functioning and positively associated with physical functioning during locomotion and activities of daily living (ADL), role-physical (i.e., physical issues during work and ADLs), and role-emotional (i.e., emotional issues during work and ADLs) after the two-year follow-up. In conclusion, screen time may positively or negatively influence some domains of HRQoL in adults.

Analysis of different domains of physical activity with health-related quality of life in adults: 2-year cohort.

BACKGROUND: It is estimated that, worldwide, 9% of deaths occur as a result of insufficient physical activity (PA) practice. Practicing PA can prevent and/or reduce the deleterious effects of different types of diseases and can improve general health aspects related to health-related quality of life (HRQoL). PURPOSE: To analyze the relationship of different PA domains with different HRQoL domains over a two-year period. METHODS: This is an observational study with a two-year longitudinal design. The sample, composed of adults, was selected from a randomization of the streets of the different regions (north, south, east, west and center) covering individuals from all areas of the city. To assess the practice of PA, the Baecke questionnaire was used. The instrument Medical Outcomes Study SF-36-Item Short Form Health Survey was used to assess the HRQoL domains. Linear regression models were used to analyzed the association of different PA domains with changes in HRQoL. Multivariate statistical models were adjusted for gender, age, socioeconomic status, marital status, the respective PA score at baseline, smoking, body mass index, and morbidity. RESULTS: 331 adults were evaluated. There was a decrease in the practice of PA in the occupational domain and an increase in the leisure/locomotion domain. Regarding HRQoL, there was an increase in the scores of body pain and mental health, and a decrease in scores of general health, vitality, social aspects and emotional aspects. The PA practice in the occupational domain was inversely related to functional capacity (ß = - 7.2 [CI 95% - 13.0; - 1.4]). The practice of PA through sports in leisure time was positively associated with vitality (ß = 5.5 [CI 95% 0.2; 10.7]) and mental health (ß = 15.2 [CI 95% 6.8; 23.7]). PA practice during leisure and locomotion was inversely associated with functional capacity (ß = - 5.68 [CI 95% - 10.7; - 0.6]) and positively associated with vitality ß = 4.8 [CI 95% 0.8; 8.7]) and mental health (ß = 8.4 [CI 95% 2.0; 14.9]). The total PA practice was inversely associated with functional capacity (ß = - 3.8 [CI 95% - 6.5; - 1.2]) and positively associated with pain in the body (ß = 4.9 [CI 95% 0.3; 9.4]), vitality (ß = 2.9 [CI 95% 0.7; 5.0]) and mental health (ß = 5.7 [CI 95% 2.2; 9.2]). CONCLUSIONS: It is suggested that practicing PA continuously within a period of two years can positively affect some physical aspects and some mental aspects related to HRQoL, but not all of them. A strategy for public policy actions is to explore these variables by domain and thus detect the real needs and improvements that can be made for the population.

Back and neck pain and poor sleep quality in adolescents are associated even after controlling for confounding factors: An epidemiological study.

OBJECTIVE: Back pain and poor sleep quality are public health issues. Relating to adolescents particularly, the way in which this relationship can occur is still unclear. The aim of this study was to investigate whether low back and neck pain are associated with sleep quality among adolescents. MATERIAL AND METHODS: In total, 1011 randomly selected adolescents participated in this study. Neck and back pain were assessed using the Nordic questionnaire, while sleep quality was assessed through the Mini-Sleep Questionnaire. The confounding variables used in the statistical analysis were age, socioeconomic status, physical activity, and body mass index. To analyze the associations between sleep quality and low back and neck pain, multivariate models and binary logistic regression were used. RESULTS: 19.9% of the girls reported low back pain while 18.9% reported neck pain. 15.6% of the boys reported low back or neck pain. Regarding low sleep quality, the prevalence was 46.0% for girls and 49.6% for boys. An association was observed between low back pain and sleep quality among girls (OR=1.98 [1.25 - 3.12]) and boys (OR=2.58 [1.48 - 4.50]). An association between neck pain and sleep quality was also observed among girls (OR=2.27 [1.41 - 3.64]) and boys (OR=2.80 [1.59 - 4.91]). CONCLUSION: Low back pain and neck pain were associated with poor sleep quality among adolescents even after the insertion of confounding variables.

Continuity of physical activity practice from childhood to adolescence is associated with lower neck pain in both sexes and lower back pain in girls.

BACKGROUND: The literature on physical activity practice through sports as a protective factor for back pain in adolescents is conflicting. However, few studies have aimed to verify if continuity of the practice of physical activity from childhood to adolescence may be related to lower chances of back pain in adolescents. OBJECTIVES: The objective of this study was to analyze the association between physical activity practice from childhood to adolescence and back pain in adolescents. METHODS: The random sample was composed of 870 adolescents with a mean age of 13.7 ± 2.0 years. The continuity of physical activity practice was assessed through the continuity of sports practice from childhood to adolescence. Pain in the neck and low back were evaluated through a questionnaire. RESULTS: The prevalence of neck pain and low back pain in boys was 17.5% and in girls was 20.9% for neck pain and 21.9% for low back pain. Physical activity practice during childhood to adolescence was a protective factor for neck pain (OR = 0.57 [CI = 0.35-0.94]) and low back pain (OR = 0.53 [CI = 0.33-0.86]) in girls and neck pain in boys (OR = 0.52 [CI = 0.30-0.90]), even after adjusting for confounding factors. CONCLUSION: Girls with physical activity practice during childhood to adolescence were less likely to develop neck pain and back pain when compared to girls who did not maintain practice of physical activity. Similar results were observed in boys considering neck pain.

Postural adjustments of active youths in perturbation and dual-task conditions / Ajustes posturais de jovens ativos em condições de perturbação e tarefa dupla / Ajustes posturales de jóvenes activos en condiciones de perturbación y doble tarea

ABSTRACT Introduction Cognitive components are necessary to maintain posture during external perturbations. However, few studies have investigated postural control when external perturbations are associated with a concomitant cognitive task (DT). Objectives To analyze the behavior of reactive adjustments after perturbation with different intensities and displacements in active young adults; and to analyze the influence of DT on predictive and reactive adjustments in different perturbation conditions. Methods Twenty-eight physically active young adults stood on an item of equipment that produced displacements of the base. Four experimental conditions were introduced in a single task (ST) and DT (cognitive-report how many times a pre-established number appeared in the audio): 1 (5 cm and 10 cm/s); 2 (5 cm and 25 cm/s); 3 (12 cm and 10 cm/s) and 4 (12 cm and 25 cm/s). Three attempts were carried out for each condition (total=24). Center of pressure (CoP) parameters were analyzed considering the following windows: predictive (-250 to +50 ms), reactive 1 (+50 to +200 ms) and reactive 2 (+200 to +700 ms), in comparison to the start of the CoP activity. One-way ANOVAs were performed to analyze predictive adjustments, while two-way ANOVAs with factor for task (STxDT) and condition (1x2x3x4), with repeated measurements, were performed for the reactive adjustments. Results One-way ANOVA (predictive) indicated that the subjects had higher CoP parameters in ST vs DT. In reactive adjustments 1 and 2, ANOVA indicated greater CoP parameters in condition 2 and 4 when compared to 1 and 3, and in the ST vs DT. The subjects took longer to recover stable position in conditions 1 and 3 than in conditions 2 and 4. Conclusion Perturbation intensity has a greater influence on postural adjustments to maintain balance than on magnitude. Moreover, the association of cognitive tasks with external perturbation decreases CoP oscillation. Therefore, cognitive resources play an important role in postural control after perturbation. Level of evidence III; Study of nonconsecutive patients, with no "gold" standard applied uniformly.

RESUMO Introdução Componentes cognitivos são necessários para manter a postura nas perturbações externas. Porém, poucos estudos investigaram o controle postural quando perturbações externas são associadas à tarefa cognitiva concomitante (TD). Objetivo Analisar o comportamento dos ajustes reativos após perturbação com diferentes intensidades e deslocamentos em adultos jovens ativos; e analisar a influência da TD nos ajustes preditivos e reativos em diferentes condições de perturbação. Métodos Permaneceram em pé sobre um equipamento que provocou deslocamento da base de suporte 28 adultos jovens fisicamente ativos. Quatro condições experimentais foram realizadas em tarefa simples (TS) e TD (cognitiva-reportar quantas vezes um número preestabelecido apareceu no áudio): uma (5cm e 10cm/s); duas (5cm e 25cm/s); três (12cm e 10cm/s) e quatro (12cm e 25cm/s). Foram realizadas três tentativas para cada condição (total=24). Os parâmetros do centro de pressão (CoP) foram analisados em janelamentos: preditivo (-250 a +50ms), reativo 1 (+50 a +200ms) e reativo 2 (+200 a +700ms), em relação ao início da atividade do CoP. ANOVAs one-way foram realizadas para análise dos ajustes preditivos. Já para os ajustes reativos, foram realizadas ANOVAs two-way com fator para tarefa (TS×TD) e condição (1×2×3×4) com medidas repetidas. Resultados ANOVA one-way (preditivo) apontou que os indivíduos apresentaram maiores parâmetros do CoP na TS em relação à TD. Nos reativos 1 e 2, a ANOVA apontou maiores parâmetros do CoP na segunda e na quarta condição quando comparada à primeira e à terceira, e na TS em relação às TD. Apresentaram maior tempo para recuperar a posição estável na primeira e na terceira condição em comparação à segunda e à quarta. Conclusão A intensidade da perturbação influencia mais nos ajustes posturais para manutenção do equilíbrio do que a magnitude. Ainda, as tarefas cognitivas concomitantes à perturbação externa diminuem a oscilação do CoP. Com isso, recursos cognitivos possuem relevância no controle postural após perturbação. Nível de evidência III; Estudos de pacientes não consecutivos, sem padrão de referência "ouro" aplicado uniformemente.

RESUMEN Introducción Los componentes cognitivos son necesarios para mantener la postura en perturbaciones externas. Sin embargo, pocos estudios investigaron el control postural cuando son asociadas perturbaciones a la tarea cognitiva concomitante (TD). Objetivo Analizar el comportamiento de los ajustes reactivos después de una perturbación con diferentes intensidades y desplazamientos en adultos jóvenes activos; y analizar la influencia de la TD en ajustes predictivos y reactivos en diferentes condiciones de perturbación. Métodos Veintiocho adultos jóvenes físicamente activos permanecieron en pie sobre un equipo que provocó desplazamiento de la base de soporte. Cuatro condiciones experimentales fueron realizadas en tareas simples (TS) y TD (cognitiva-reportar cuántas veces un número preestablecido apareció en el audio): una (5 cm y 10 cm/s); dos (5 cm y 25 cm/s); tres (12 cm y 10 cm/s) y cuatro (12 cm y 25 cm/s). Fueron realizadas tres tentativas para cada condición (total=24). Los parámetros del centro de presión (CoP) fueron analizados en ventanas: predictiva (-250 a +50 ms), reactiva 1 (+50 a +200 ms) y reactiva 2 (+200 a +700 ms) en relación al inicio de la actividad del CoP. Fueron realizadas ANOVAs one-way para análisis de los ajustes predictivos. Fueron realizadas ANOVAs two-way con factor para tarea (TSxTD) y condición (1x2x3x4) con medidas repetidas para análisis de los ajustes reactivos. Resultados ANOVA one-way (predictivo) mostró que los individuos presentaron parámetros mayores de CoP en TS con relación a TD. En los reactivos 1 y 2, ANOVA mostró parámetros del CoP en la segunda y cuarta condición cuando comparada a la primera y la tercera, y en la TS con relación a las TD. Presentaron tiempo mayor para recuperar la posición estable en la primera y tercera condición en comparación a la segunda y la cuarta. Conclusión La intensidad de perturbación influencia más en los ajustes posturales para mantenimiento del equilibrio que la magnitud. Además, las tareas cognitivas concomitantes a la perturbación externa disminuyen la oscilación del CoP. Con eso, los recursos cognitivos poseen relevancia en el control postural después de la perturbación. Nivel de evidencia III; Estudios de pacientes no consecutivos, sin estándar de referencia "oro" aplicado uniformemente.

Relationship of different domains of physical activity practice with health-related quality of life among community-dwelling older people: a cross-sectional study.

OBJECTIVE: To analyse the association between different domains of physical activity (PA) and health-related domains of health-related quality of life (HRQoL) in older adults, independent of confounding variables. DESIGN: Cross-sectional study. PARTICIPANTS: In total, 400 individuals 60 years or above were randomly selected to participate in the study. PRIMARY AND SECONDARY OUTCOME MEASURES: PA was assessed by a questionnaire in three different domains (work/occupational, sports/gym and leisure time) and total PA. The 36-Item Short Form Health Survey was used to evaluate HRQoL. The variables socioeconomic condition, marital status and presence of health professional-diagnosed comorbidities were self-reported. RESULTS: The mean age of the sample was 71.5 (±8.4) years, of whom 58% (n=232) were female. Male older adults showed higher scores of PA in sports, leisure time and in total PA than female adults. Older adults who were more physically active in the work/occupational domain were associated with better scores in functional capacity (OR=1.73, 95% CI 1.02 to 2.93) and general health perception (OR=1.61, 95% CI 1.02 to 2.56). Those who presented a higher score in the sports/gym domain had better scores in functional capacity, even after adjustment for comorbidities (OR=1.72, 95% CI 1.01 to 2.96). Individuals with higher activity in leisure time were more likely to have better scores in functional capacity (OR=1.75, 95% CI 1.03 to 2.98), body pain (OR=1.74, 95% CI 1.09 to 2.78) and mental health (OR=1.67, 95% CI 1.03 to 2.69). Older adults who were more active in total PA were 77% more likely to have better scores in functional capacity (OR=1.77, 95% CI 1.04 to 3.02). CONCLUSION: Physically active older adults in the different domains of PA presented better HRQoL parameters, reinforcing the importance of studies analysing PA in different contexts and in countries with low and medium socioeconomic conditions.

Smoking among adolescents is associated with their own characteristics and with parental smoking: cross-sectional study

ABSTRACT BACKGROUND: This study aimed to analyze the association between smoking during adolescence and the characteristics of smoking and alcohol consumption among their parents. DESIGN AND SETTING: Cross-sectional study in Londrina (PR), Brazil. METHODS: The subjects comprised 1,231 adolescents aged 14-17 years. The adolescents and their parents answered a self-report questionnaire that asked for sociodemographic information and data on smoking and alcohol consumption. Multiple logistic regression models were used to analyze associations between smoking among adolescents and their characteristics (age, sex, period of the day for attending school, alcohol consumption and socioeconomic level) and their parents' characteristics (smoking, alcohol consumption, age and education level), adjusted according to the adolescents' characteristics (sex, age and socioeconomic level). RESULTS: The prevalence of smoking among adolescents was 3.4% (95% confidence interval, CI: 2.4-4.4). Adolescents whose mothers or fathers were smokers were 2.0 and 2.5 times more likely to be smokers, respectively. The prevalence of smoking among adolescents with a smoking mother was 7.1% (95% CI: 2.6-10.7) and a smoking father, 5.4% (95% CI: 1.6-8.5). There were significant associations between smoking adolescents and age [5.2% (95% CI: 3.3-6.6)], studying at night [9.6% (95% CI: 4.0-15.5)] and alcohol consumption [69.0% (95% CI: 55.0-83.0)]. It was observed that the number of alcoholic beverage doses consumed was higher among smoking adolescents (P = 0.001). CONCLUSION: Adolescent smoking was associated with smoking by their parents, regardless of the gender of the parents or adolescents. Age, alcohol consumption and studying at night are characteristics of adolescents that can contribute towards smoking.

Back and neck pain prevalence and their association with physical inactivity domains in adolescents.

PURPOSE: Back pain affects people of all ages. This may be associated with physical inactivity, and in the case of physical activity in different domains, the relationship with back pain is not clear in the literature. The aim of this study was to estimate the prevalence of low back and neck pain and investigate their association in different domains of physical inactivity. METHODS: 1011 randomly selected students participated in this study. Neck and back pain were assessed using the Nordic questionnaire, whereas the Baecke Physical Activity questionnaire was used to measure physical activity domains. Separate Binary Logistic Regression models were performed to investigate the association of physical activity domains with neck or back pain. RESULTS: 17.4% of the students reported cervical pain, while 18.0% reported low back pain. Older adolescents had a higher prevalence of cervical pain (24.4%) than younger adolescents (11.9%) (p value <0.001), as well as lumbar pain, being 25.1% in older adolescents and 12.4% in younger (p value <0.001). Adolescents physically inactive in the school environment were less likely to have pain in the cervical region [OR 0.67 (0.44-0.99)] or back pain [OR 0.60 (0.40-0.91)]. Being inactive in occupational activities was associated with cervical pain [OR 1.49 (1.06-2.10)]. Being inactive in the sports environment presented a marginal relationship with pain in the cervical region [OR 1.41 (0.99-2.02)]. CONCLUSIONS: The prevalence of neck and low back pain was higher in older adolescents and physical inactivity in the sporting context and occupational activities could be a risk factor to increase the chances of back pain.

Influence of physical exercise on the functional capacity in institutionalized elderly / Influência do exercício físico na capacidade funcional de idosos institucionalizados / Influencia del ejercicio físico en la capacidad funcional de ancianos institucionalizados

ABSTRACT Introduction: With the rapid increase in life expectancy, systematic physical exercise programs can have a good influence on the functional capacity of the elderly, especially in relation to institutionalization. Objective: To analyze the association between a systematic physical exercise program and functional capacity in institu-tionalized elderly. Methods: The sample included 30 elderly subjects (16 women and 14 men) aged 60 years or older (mean age = 74.43), divided into a control group (n=16) and a training group (n=14), residents in a long-stay institution. A training protocol of 12 weeks, two weekly sessions, was applied, and functional capa-city was assessed before and after the intervention, through chair lift tests (lower limb strength), upper limb strength, timed up and go and handgrip dynamometry. The analysis pre and post-training of intervention and control groups was performed using paired Student t test and the ANOVA test for repeated measures. The level of significance was set at 5%. Results: The main statistical significance were found for the following functional tests: upper limb strength (training 15.6±4.1 x control 10.7±6.6 rep, p<0.05) and chair lift test (training 11.0±4.0 x control 8.0±3.1 rep, p<0.05). Conclusion: The protocol used proved to be effective in improving some of the functional capabilities of the institutionalized elderly.
