The impact of early sports participation on body fatness in adulthood is not mediated by current physical activity.

OBJECTIVE: The aim was to analyze the relationship between early sports participation (ESP) and body fatness (BF) in adults, as well as to identify whether this possible relationship is directly influenced by the current physical activity (PA) level. METHODS: This cross-sectional study combined baseline data of two cohort. The BF estimated by DXA. The ESP, the subjects reported the engagement in sports during childhood (7-10 years) and adolescence (11-17 years) through two yes/no questions and current PA (described as steps) was device-measured using pedometers. Were identified as potential covariates and therefore adjusted the multivariate models: age, ethnicity, alcohol consumption, smoking, and sleep quality. Statistical analysis consisted of the chi-square test, analysis of variance/covariance, and structural equation modeling (software BioEstat version 5.0; p-value < .05). RESULTS: Adults engaged in ESP had lower BF; among women, the variance in BF explained by ESP was 25.5%; among men, it was 9.2%. Sports participation in early life (r = -.436 [95% CI: -0.527 to -0.346]) and current PA (r = -.431 [95% CI: -0.522 to -0.340]) were inversely related to BF, as well as positively related to each other (r = .328 [95% CI: 0.226 to 0.430]). In the mediation model, current PA partially mediated (18.5%) the impact of ESP on BF, while current PA and ESP remained relevant determinants of BF. CONCLUSION: Early sports participation and current PA have a significant impact on BF in adulthood, which is of similar magnitude and independent of each other.

Productivity Loss, Healthcare Costs, and Habitual Physical Activity Among Adults With Cardiovascular Diseases.

OBJECTIVES: The aims of the study are to quantify the relationship between productivity loss and healthcare costs among adults with cardiovascular diseases and also to verify whether habitual physical activity (HPA) modulates this relationship. METHODS: Information was obtained about healthcare costs, productivity loss, and HPA. RESULTS: The sample consisted of 278 adults. Active workers who reported presenteeism and absenteeism due to cardiovascular diseases had higher direct costs ( P < 0.05) than those who reported other reasons. Those who reported absenteeism spent US $187.33 more on healthcare services annually than those who did not miss work because of health reasons. However, an annual savings of US $53.00 was observed for each increase in the score of HPA. CONCLUSIONS: There was a positive correlation between absenteeism and direct healthcare costs among adults with cardiovascular diseases, and HPA positively affected this relationship.

Impact of physical activity during weekdays and weekends on fat mass among adults: 12-month cohort study

ABSTRACT BACKGROUND: Physical activity (PA) practices seem to differ between weekdays and weekends and these pattern changes can affect body fat differently. However, previous studies did not assess the mediation effect of weekday and weekend PA on maintenance of body fat using sophisticated statistical models. OBJECTIVE: To analyze the mediation effect of PA during weekdays and weekends on maintenance of fat mass over a 12-month follow-up. DESIGN AND SETTING: Longitudinal cohort study (12 months) conducted at a public university in Presidente Prudente, Brazil. METHODS: A sample of 225 adults (117 females) was used. Body fatness and fat mass were assessed using dual-energy X-ray absorptiometry. PA levels were assessed using a pedometer. The statistical analysis consisted of paired-sample t tests, independent-sample t tests, Pearson correlations and mediation models. RESULTS: After 12 months, weekend PA had decreased while body composition indicators remained stable (without changes). The correlation between fat mass at baseline and follow-up was high for both sexes (men: 0.966; women: 0.941; P-value = 0.001 for both). Moreover, PA indices were inversely but moderately related to fat mass at baseline and follow-up. Lastly, weekend PA mediated the association between fat mass at baseline and follow-up (P-value < 0.05) by around 2% and 4%. CONCLUSION: Weekend PA mediated the association between fat mass at baseline and fat mass after one year of follow-up among these adults. Further studies are required to investigate the association between physical activity, body fat and other variables such as dietary patterns and sleep time.

Obesity Increases Costs With Productivity Loss Due to Disability Retirements, Independent of Physical Activity: A Cohort Study.

OBJECTIVE: Investigate whether obesity is responsible for costs due to productivity loss (PL) in adults, during 30 months of follow-up. METHODS: Absenteeism and disability retirement were considered as PL. For classification of obesity, body mass index (BMI) and waist circumference (WC) values were considered. The statistical software BioEstat (release 5.0) was used and the significance level was set at P value < 0.05. RESULTS: For the men, BMI and WC accounted for ∼60% and ∼30% of retirement due to disability (P = 0.001). For the women, this percentage represented ∼19% for BMI and ∼8% for WC, both P < 0.05. Physical activity was not a significant confounder in any of the analyses (P > 0.05). CONCLUSION: Total and abdominal obesity were responsible for increased costs from PL due to early retirement among adults aged 50 years or older.

Effects of group kinesiotherapy on primary and secondary symptoms of osteoarthrosis

The aim of this study was to investigate the influence of a specific, kinesiotherapy-based rehabilitation program on the various symptoms of osteoarthrosis (OA), following group treatment. Thirty-one individuals, of both sexes, aged over 50 years and with medical diagnosis of OA, underwent 16 sessions, twice a week, totaling eight weeks, of a specific rehabilitation protocol based on group kinesiotherapy. Primary OA symptoms were assessed (directly related to the disease: OA symptoms, trunk flexibility, balance and pain), and so were secondary ones (indirectly related to the disease: signs of depression and anxiety, and quality of life). Data were tested through Student's t test or Wilcoxon's test, and contingencies of categorical data were analyzed using McNemar's test. There was an improvement in all primary symptoms of OA after the kinesiotherapy protocol was applied. Signs of anxiety and depression improved only in contingency, when risk stratification was taken into account. In addition, physical components of quality of life also showed improvement, which did not occur with mental components though. Therefore, the kinesiotherapy-based rehabilitation program was capable of positively influencing all primary symptoms, and only some aspects of secondary OA symptoms.

Associação entre qualidade do sono e doenças cardiometabólicas de pacientes da Atenção Primária à Saúde / Association between sleep quality and cardiometabolic diseases of primary care system patients

A privação do sono está relacionada ao desenvolvimento de doenças cardiometabólicas. O objetivo deste estudo foi analisar a associação entre qualidade do sono e ocorrência de doenças cardiometabólicas em adultos atendidos na Atenção Primária à Saúde. Estudo longitudinal composto por 169 adultos (68,6% do sexo feminino), média de idade 61,80 (desvio padrão = 8,80), acompanhados por 30 meses. A presença das doenças hipertensão arterial, dislipidemia, diabetes mellitus e ocorrência de infarto e a qualidade do sono foram mensuradas por meio de questionários. Os participantes foram divididos em grupos de acordo com a qualidade do sono (adequada/inadequada). Para verificar a diferença de idade, classe econômica, atividade física habitual e circunferência de cintura, entre os grupos a e b, utilizou-se o teste t de Student para amostras independentes. Para comparar a proporção das doenças (hipertensão arterial, infarto, diabetes e dislipidemias) entre os grupos, utilizou-se o teste Qui-quadrado com correção de Yates. A regressão logística binária foi utilizada para testar a magnitude de tais associações, ajustadas por sexo, idade, atividade física, obesidade abdominal, etilismo e tabagismo. As análises estatísticas foram realizadas no software BioEstat (versão 5.0) e o nível de significância adotado foi de p < 0,05. Verificou-se que 83,4% dos adultos reportaram ao menos uma alteração na qualidade do sono e os que apresentaram inadequada qualidade do sono tiveram 3,4 vezes mais chances de reportar diabetes (OR = 3,47; IC95%: 1,06-11,30), comparados aos com o sono adequado. Inadequada qualidade do sono parece contribuir para o aumento da ocorrência de diabetes mellitus, independente do tempo de prática de atividade física e a obesidade abdominal

Sleep deprivation is related to the development of cardiometabolic diseases. The aim of this study was to analyze the association between sleep quality and occurrence of cardiometabolic diseases in adults attending Primary Health Care. Longitudinal study of 169 adults (68.6% female), mean age 61.80 (deviation = 8.80), followed for 30 months. The presence of the diseases hypertension, dyslipidemia, diabetes mellitus and occurrence of infarction and the quality of sleep were measured using questionnaires. Participants were divided into groups according to sleep quality (adequate / inadequate). To verify the difference in age, economic class, habitual physical activity and waist circumference, between groups a and b, the Student's t test for in-dependent samples was used. To compare the proportion of diseases (hypertension, heart attack, diabetes, and dyslipidemia) between the groups, the chi-square test with Yates correction was used. Binary logistic regression was used to test the magnitude of such associations, adjusted for gender, age, physical activity, abdominal obesity, alcoholism and smoking. Statistical analyzes were performed using BioEstat software (version 5.0) and the significance level adopted was p <0.05. 83.4% of adults reported at least one change in sleep quality and those with inadequate sleep quality were 3.4 times more likely to report diabetes (OR = 3.47; 95%CI: 1.06 -11.30) compared to those with adequate sleep. Inadequate sleep quality seems to contribute to the increased occurrence of diabetes mellitus, regardless of the length of physical activity and abdominal obesity

The Relationship between Lifestyle and Costs Related to Medicine Use in Adults.

BACKGROUND: The unhealthy lifestyle is growing and this can have repercussions on health status demanding actions on the occurrence of diseases and leads to increased expenses. OBJECTIVE: To examine the interrelationship between the costs of medicine use and lifestyle behaviors. METHODS: A cohort study with 118 participants, age around 51.7 ± 7.1 years old. It was collected personal and anthropometric data and information about medicine of continuous use to calculate the costs. Lifestyle variables included habitual physical activity (PA) assessed by pedometer, sedentary behavior by Baecke questionnaire, sleep quality by mini sleep questionnaire and self-report of smoke and alcohol consumption. Statistical analyses were performed by BioEstat (version 5.2) and the significance level set at p-value < 0.05. RESULTS: In 12 months, 62 subjects bought 172 medicines, representing an overall cost of US$ 3,087.01. Expenditures with drugs were negatively related to PA (r = -0.194, p-value = 0.035 and r = -0.281, p-value = 0.002), but positively related with sleep quality (r = 0.299, p-value=0.001 and r = 0.315, p-value = 0.001) and age (r = 0.274, p-value = 0.003). Four multivariate models were executed considering lifestyle behaviors in different moments of cohort and medicine costs, and all these models identify important relationship between lifestyle behaviors with expenditures with drugs. CONCLUSION: Worse sleep quality seems to increase the costs related to medicine use in adults, while obesity and ageing play a relevant role in this phenomenon and alcohol consumption seems a variable with relevant economic impact.

Adults Engaged in Sports in Early Life Have Higher Bone Mass Than Their Inactive Peers.

PURPOSE: To analyze the relationship between engagement in sports in early life and bone variables among adults of both sexes. METHODS: The sample was composed of 225 men and women. Demographic data were collected, and dual-energy X-ray absorptiometry was used to assess bone mineral density, bone mineral content, and lean soft tissue. Sports participation in early life was assessed by an interview including childhood and adolescence. Consumption of tobacco and alcohol was also assessed by interview and the habitual physical activity level by a pedometer. RESULTS: Inactive men had bone mineral content around 11% lower than active men in childhood or adolescence, whereas for women, this difference represented around 14%. Active men had 74% less fat mass than inactive men in early life, and the difference was 67% for women. Early sports participation explained the differences in whole-body bone mineral content (16.8%, P-value = .005) and bone mineral density (8.8%, P-value = .015), as well as bone mineral density in lower limbs (18.9%, P-value = .001) among women. CONCLUSION: Adults engaged in sports in early life have higher bone mass than their inactive peers, especially women.

Sports practice and bone mass in prepubertal adolescents and young adults: a cross-sectional analysis

Abstract AIM: To compare bone mass and body composition variables between adolescents engaged in high-impact sports and adults who were sedentary during early life. METHOD: A cross-sectional study with 155 participants (64 adolescents and 91 adults) aged between 11 and 50 years old. Among the adults, history of sports was evaluated during face-to-face interviews, and information regarding the adolescents' training routines was provided by their coaches. Body composition was evaluated using Dual Energy X-Ray Absorptiometry which provided data about bone mineral density (BMD), bone mineral content (BMC), fat mass (FM), and free fat mass (FFM). RESULTS: Adults who engaged in sports practice during early life had higher values of BMC (ES-r = 0.063), FFM (ES-r = 0.391), and lower values of FM (ES-r = 0.396) than sedentary adults. Higher values of BMC (ES-r = 0.063) and BMD in lower limbs (ES-r = 0.091) were observed in active adolescents. Adolescents engaged in sports and adults who were sedentary in early life presented similar values in all bone variables, FM, and FFM. CONCLUSIONS: Sports involvement in early life is related to higher bone mass in adulthood. Adolescents engaged in sports presented similar bone mass to adults who had been sedentary in early life.

Vasculopathy associated with peripheral neuropathy in gait parameters of diabetic people

Abstract Diabetic peripheral neuropathy (DPN) is a common complication of diabetes mellitus when glycemic levels are poorly controlled. Sometimes DPN is accompanied by vasculopathy (DPV), which can worsen the clinical prognosis. The aim of this study was to analyze the gait parameters of nondiabetic individuals and diabetic individuals with DPN with or without DPV. METHOD The study included 68 individuals (50 to 65 years old) divided into three groups: people without diabetes mellitus (n = 33), diabetic patients with DPN (n = 18), and diabetic patients with both DPN and DVP (n = 17). The participants underwent a gait evaluation using electronic baropodometry to obtain the single and double support, velocity, and pressure-time integral. RESULTS The pressure-time integral, velocity, and single support variables were lower, and the double support and double support/single support ratio were higher in the diabetic neuropathy and vasculopathy group. The velocity was lower the greater the degree of impairment of the diabetic foot. Some correlations were identified with velocity. CONCLUSION In diabetic individuals, there was a significant worsening of the gait parameters analyzed according to increasing degree of clinical impairment.

The relationship between post-operative time and cardiac autonomic modulation in breast cancer survivors.

BACKGROUND/OBJECTIVES: Breast cancer survivors present autonomic dysfunction when evaluated by their heart rate variability (HRV). The purpose of this study is to investigate the relationship between post-operative time and cardiac autonomic modulation in breast cancer survivors and compare these values to those of women without cancer. METHODS: This is a cross-sectional study consisting of 45 women from 35 to 70years old. These women were divided into two after breast cancer groups (BCG1 and BCG2) and a control group (CG). Group BCG1 consisted of women who had undergone breast cancer surgery within the last 18months and BCG2 those whose postoperative periods were more than 18months. The control group was formed by cancer-free women. HRV indices were used in the time and the frequency domain and geometric indexes. RESULTS: The indices in millisecond, RMSSD (BCG1=19.83; BCG2=14.99; CG=31.46), SD1 (BCG1=14.03; BCG2=10.61; CG=22.27), SD2 (BCG1=39.17; BCG2=35.28; CG=61.16), SDNN (BCG1=29.58; BCG2=26.12; CG=46.36) and HF in milliseconds squared (BCG1=194.2; BCG2=91.07; CG=449.4) showed statistically significant reductions in the breast cancer groups compared to the CG (p≤0.0001). Lower SD1 index values were observed when comparing BCG2 to BCG1. CONCLUSIONS: Breast cancer survivors regardless of their postoperative period exhibited a decrease in overall variability and both sympathetic and parasympathetic activity when compared to women without the disease. The group with the longer postoperative period manifested more pronounced autonomic modulation changes.

Different Amounts of Physical Activity Measured by Pedometer and the Associations With Health Outcomes in Adults.

BACKGROUND: Physical activity level is an important tool to identify individuals predisposed to developing chronic diseases, which represent a major concern worldwide. OBJECTIVE: To identify correlates of daily step counts measured using pedometers, as well as analyze the associations between health outcomes and 3 different amounts of daily physical activity. METHODS: The sample comprised 278 participants (126 men and 153 women) with a mean age of 46.51 ± 9.02 years. Physical activity was assessed using pedometers for 7 consecutive days, and 3 amounts of daily physical activity were considered: ≥10,000 steps/day, ≥7500 steps/day, and <5000 steps/day. Sleep quality was assessed through a questionnaire, and dual-energy x-ray absorptiometry was used to measure body fat. Sociodemographic and anthropometric data were also collected. RESULTS: The percentages of adults achieving at least 10,000 and 7500 steps/day on a minimum of 5 days of the evaluated week were 12.9% and 30.9%, respectively. Adults who reached ≥7500 steps/day had a lower likelihood of being obese (odds ratio [OR] = 0.38, 95% confidence interval [CI], 0.17-0.85) and reporting worse sleep quality (OR = 0.58, 95% CI, 0.34-0.99). Adults who reached <5000 steps/day had a higher likelihood of reporting worse sleep quality (OR = 2.11, 95% CI, 1.17-3.82). CONCLUSION: Physical activity in adulthood, as measured by pedometer, constituted a behavior related to lower adiposity and better sleep quality.

Practice of martial arts and bone mineral density in adolescents of both sexes / Prática de artes marciais e densidade mineral óssea em adolescentes de ambos os sexos

Objective: The purpose of this study was to analyze the relationship between martial arts practice (judo, karate and kung-fu) and bone mineral density in adolescents. Methods: The study was composed of 138 (48 martial arts practitioners and 90 non-practitioners) adolescents of both sexes, with an average age of 12.6 years. Bone mineral density was measured using Dual-Energy X-ray Absorptiometry in arms, legs, spine, trunk, pelvis and total. Weekly training load and previous time of engagement in the sport modality were reported by the coach. Partial correlation tested the association between weekly training load and bone mineral density, controlled by sex, chronological age, previous practice and somatic maturation. Analysis of covariance was used to compare bone mineral density values according to control and martial arts groups, controlled by sex, chronological age, previous practice and somatic maturation. Significant relationships between bone mineral density and muscle mass were inserted into a multivariate model and the slopes of the models were compared using the Student t test (control versus martial art). Results: Adolescents engaged in judo practice presented higher values of bone mineral density than the control individuals (p-value=0.042; Medium Effect size [Eta-squared=0.063]), while the relationship between quantity of weekly training and bone mineral density was significant among adolescents engaged in judo (arms [r=0.308] and legs [r=0.223]) and kung-fu (arms [r=0.248] and spine [r=0.228]). Conclusions: Different modalities of martial arts are related to higher bone mineral density in different body regions among adolescents.

Objetivo: Analisar a relação entre a prática de artes marciais (judô, karatê e kung-fu) e a densidade mineral óssea em adolescentes. Métodos: O estudo foi composto por 138 adolescentes (48 praticantes de artes marciais e 90 não praticantes) de ambos os sexos, com média de 12,6 anos. A densidade mineral óssea foi medida com absortometria radiológica de dupla energia em braços, pernas, coluna, tronco, pelve e total. A carga de treinamento semanal e o tempo anterior de envolvimento na modalidade esportiva foram relatados pelo treinador. A correlação parcial testou a associação entre a carga semanal de treinamento e a densidade mineral óssea, controlada para sexo, idade cronológica, prática anterior e maturação somática. A análise de covariância foi usada para comparar os valores de densidade mineral óssea de acordo com os grupos controle e de artes marciais, controlados para sexo, idade cronológica, prática anterior e maturação somática. Associações significativas entre a densidade mineral óssea e a massa muscular foram inseridas em um modelo multivariado e as inclinações dos modelos foram comparadas com o teste t de Student (controle versus arte marcial). Resultados: Os adolescentes envolvidos na prática de judô apresentaram valores maiores de densidade mineral óssea do que os do grupo controle (p=0,042; tamanho de efeito médio [eta-quadrado=0,063]), enquanto a relação entre a quantidade de treinos semanais e a densidade mineral óssea foi significativa entre os adolescentes praticantes de judô (braços [r=0,308] e pernas [r=0,223]) e kung-fu (braços [r=0,248] e coluna [r=0,228]). Conclusões: Diferentes modalidades de artes marciais estão relacionadas com maior densidade mineral óssea em diferentes regiões do corpo em adolescentes.

Immediate effect of basic body awareness therapy on heart rate variability.

OBJECTIVE: To determine the immediate effect of a Basic Body Awareness Therapy (BAT) session on measures of heart rate variability (HRV) in healthy young people. METHODS: 13 healthy young subjects of both genders, who showed no illnesses related to the autonomic nervous system (ANS) underwent an ANS evaluation before and after conducting a session of BAT. The assessment of ANS activity was conducted through the HR with the aid of Nerve-Express(®) software. The BAT session lasted for 50 min and was performed by one investigator (blinded to the assessment procedures). RESULTS: After BAT session significant improvement was found in the sympathetic and parasympathetic modulation (p < 0.05), and the general estimate of heart rate variability (p < 0.04). CONCLUSION: BAT was found to be an effective, easy to apply and inexpensive therapeutic technique, able to change ANS in order to improve HR which may suggest better health conditions for participating individuals.

Occurrence of physical therapy consultations in the last 12 months among adults from a medium sized brazilian city / Ocorrência de consultas fisioterápicas nos últimos 12 meses entre adultos de uma cidade de porte médio brasileira

Cross-sectional design. Introduction: Physical Therapy is a profession with a diversity of methods and s, and although it extends to all age groups with a huge number of clinics, the occurrence of searches for physiotherapists is still low. Aim: To analyze the occurrence of physical therapy consultations in the past 12 months among adults in Presidente Prudente, as well as to identify some variables associated with the outcome. Methods: The population (n=743) had a mean age of 49.9±17.3 years. The procedures set out the dependent variable: physical therapy consultation and independent variables: low back pain and physical activity during leisure time and at work, respecting the confounding factors. Results: The occurrence of physiotherapy consultations in the last 12 months was 21%, which was more frequent among adults of 30-44.9 years (OR=2.02 [1.02-3.99]) and for those with low back pain (OR=2.18 [1.18-4.06]). Conclusion: Physical therapy utilization is an outcome with a low rate, which is associated with low back pain among adults at a productive age.

Análise do controle postural em diferentes condições por meio de cinemetria / Analysis of postural control in different conditions by means of cinemetry

Introdução: A literatura científica ainda é sedenta de estudos que tragam dados normativos para variáveis relacionadas ao controle postural em diferentes populações, sobretudo, na população senescente, a qual frequentemente sofre com tais alterações. Objetivo: Avaliar a oscilação corporal de mulheres durante a postura ereta, em diferentes condições: com os olhos abertos, olhos fechados e com diminuição da base de sustentação. Método: Trata-se de um estudo transversal observacional. Participaram do estudo 14 mulheres, 63,5 ± 5,86 anos, com entradas sensoriais preservadas (visual, vestibular e somatos sensorial). Para avaliação do desempenho do sistema de controle postural, durante a manutenção da postura em pé, foi analisada a oscilação ântero-posterior e médio-lateral do corpo por sistema de cinemetria em três condições: com olhos abertos, olhos fechados e diminuição da base de sustentação (semi tandem). A análise estatística foi realizada por meio do teste de ANOVA para medidas repetidas e post hoc de Tukey. Resultados: Evidenciou-se diferença significante entre as três condições da avaliação do controle postural para as variáveis amplitudes de oscilação médio-lateral (p<0,001), velocidade de oscilação antero-posterior (p= 0,013) e velocidade de oscilação médio-lateral (p<0,001). Conclusão: os sistemas sensoriais somatossensorial, visual e vestibular mostraram-se fundamentais para a manutenção do controle motor. Ainda, com o presente estudo foi confirmada a necessidade de uma boa base de sustentação podálica para manutenção da postura e do controle postural.

Introduction: The scientific literature is still poor of studies that offers normative data for variables related to postural control in different populations, especially in senescent population which often suffers from such changes. Aim: To evaluate oscillation body in women during stance, in different conditions: eyes open, eyes closed and reduced support base. Method: It’s an observational cross-cut study. The study included 14 women with preserved sensory inputs (visual, vestibular and somatosensory). For the evaluation of performance of the postural control system, while maintaining the standing posture, was analyzed the oscillation anteroposterior and mediolateral body system kinematics by three conditions: with eyes open, eyes closed and decreased base support (semi-tandem). Statistical analysis was performed by the ANOVA of repeated measures test with the Tukey post hoc. Results: There were significant differences among the three conditions for the assessment of postural control for variables oscillation amplitude mediolateral (p<0.001), oscillation speed anteroposterior (p= 0.013) and speed mediolateral oscillation (p<0.001). Conclusion: sensory systems somatosensory, visual and vestibular proved fundamental to the maintenance of motor control. Still, the present study confirmed the need for a good support base podalic maintenance of posture and postural control.

Still, the present study confirmed the need for a good support base podalic maintenance of posture and postural control. (AU)
