Habitual physical activity and sedentary behavior as predictors of dynapenia in older adults: a cross-sectional study

ABSTRACT BACKGROUND: Dynapenia is a risk factor of mortality. Therefore, the development of low-cost and easy-to-apply tools is essential to optimize the health surveillance actions of older people. OBJECTIVES: To compare the time spent on habitual physical activity (HPA) and sedentary behavior (SB) among dynapenic and non-dynapenic older adults and ascertain the predictive ability of these behaviors on outcome. DESIGN AND SETTING: A cross-sectional population epidemiological survey was conducted involving 208 older adults. METHODS: HPA and SB were quantified using the International Physical Activity Questionnaire, and dynapenia was identified by handgrip strength (women: 18.37 kgf; men: 26.75 kgf). RESULTS: The prevalence was 24.50%. In both sexes, dynapenic individuals reported a HPA median time of 70.00 minutes/week (min/wk), while non-dynapenic women and men reported HPA median times of 240.00 and 280.00 min/wk, respectively (P < 0.05). For SB among dynapenic individuals, a median of 388.75 min/day was observed in women and 428.57 min/d in men. In contrast, non-dynapenic women and men had 291.42 and 274.28 min/day in SB (P < 0.05), respectively. The best cutoff HPA to discriminate the outcome was 150.00 min/wk in women (sensitivity: 73.30%; specificity: 60.67%) and 140.00 min/wk in men (sensitivity, 71.43%; specificity, 61.54%). The best cutoff SB was 381.43 min/day in women (sensitivity, 53.30%; specificity, 84.80%) and 351.43 min/day in men (sensitivity, 71.43%; specificity, 73.85%). CONCLUSION: Older individuals with dynapenia spent less time on HPA and more time in SB. Furthermore, HPA was found to be a better discriminator of dynapenic individuals, and SB better discriminated non-dynapenic individuals.

Características e estratégias de aconselhamento para atividade física utilizadas por profissionais da atenção primária à saúde / Characteristics and counseling strategies for physical activity used by primary health care professionals

Resumo O estudo buscou descrever as características e estratégias de aconselhamento para atividade física utilizadas por profissionais da atenção primária à saúde (APS). Foi realizada uma pesquisa com 587 profissionais de saúde (85,4% mulheres) que atuam na APS de Florianópolis, no estado de Santa Catarina, Sul do Brasil. Foram considerados os aconselhamentos efetuados nos últimos 12 meses, avaliando-se aspectos operacionais relacionados às práticas e estratégias utilizadas. A frequência de orientação de atividade física foi de 86,2% (IC95% = 83,2-88,8%). O aconselhamento se caracterizou como uma prática breve, realizada em consultas individuais, voltadas para adultos e idosos e pessoas com morbidades. A estratégia mais utilizada foi orientar usuários a participarem de grupos de atividade física no Centro de Saúde (89,5%), e em relação ao método 5As, dar algum "conselho" foi a estratégia mais utilizada (99,0%), e a menos utilizada foi seguir estratégias (22,6%). Aconselhamento para atividade física tem sido baseado em uma prática breve, realizada em consultas individuais e focada em pessoas com morbidades e em adultos e idosos. As estratégias utilizadas parecem não abranger o cuidado integral dos usuários aconselhados.

Abstract This study aim to describe the characteristics and strategies of counseling for physical activity used by Primary Health Care (PHC) professionals. A survey was carried out with 587 (85.4% women) health professionals who work in PHC in Florianopolis, in the state of Santa Catarina, southern Brazil. Counseling carried out in the last 12 months was considered. Operational aspects related to counseling practices and strategies used for counseling were evaluated. The frequency of physical activity guidance was 86.2% (95%CI = 83.2-88.8%). Counseling was characterized as a brief practice, carried out in individual consultations, aimed at adults and the older adults and people with morbidities. The most used strategy was to guide users to participate in physical activity groups at the Health Center (89.5%) and in relation to the 5As method, giving some "advice" was the most used strategy (99.0%) and the least used. used was to follow strategies (22.6%). Counseling for physical activity has been based on a brief practice, carried out in individual consultations and focused on people with morbidities and on adults and the elderly. The strategies used do not seem to cover the full care of the advised users.

Actividad física durante el embarazo y su relación con la ganancia de peso gestacional / Physical activity during pregnancy and its relationship with gestational weight gain / Atividade física durante a gestação e sua relação com o ganho de peso gestacional

Objetivo: describir los patrones de actividad física de una cohorte de gestantes de nuestro medio y explorar su asociación con la ganancia de peso en cada uno de los trimestres del embarazo. Método: estudio descriptivo longitudinal sobre una muestra de 151 mujeres. Se utilizó el Cuestionario Internacional de Actividad Física para evaluar la actividad física durante el embarazo en función del volumen, intensidad y ámbito de realización. Se llevaron a cabo diferentes modelos de regresión lineal múltiple para analizar la asociación entre actividad física y ganancia de peso gestacional. Resultados: la actividad física disminuyó durante el embarazo, tanto en tiempo como en intensidad. El índice de masa corporal pre-gestacional fue el principal factor asociado con una menor ganancia de peso a lo largo de todo el embarazo. La influencia de la actividad física sobre la ganancia de peso gestacional se limitó al tercer trimestre del embarazo en el que se observó una asociación inversa entre ambas variables. Conclusión: los resultados de este estudio muestran un importante descenso de la actividad física en la época del embarazo y sugieren una influencia limitada de ésta sobre la ganancia de peso gestacional.

Objective: to describe the physical activity patterns of a cohort comprised by pregnant women from our environment and to explore its association with weight gain in each of the trimesters of pregnancy. Methods: a descriptive and longitudinal study conducted with a sample of 151 women. The International Physical Activity Questionnaire was used to assess physical activity during pregnancy based on volume, intensity and setting where it is performed. Different multiple linear regression models were performed to analyze the association between physical activity and gestational weight gain Results: physical activity decreased during pregnancy, both in terms of time and intensity. Pre-gestational Body Mass Index was the main factor associated with lower weight gain throughout pregnancy. The influence of physical activity on gestational weight gain was limited to the third trimester of pregnancy, where an inverse association was observed between both variables. Conclusion: the results of this study show an important reduction in physical activity during pregnancy and suggest that it exerts a limited influence on gestational weight gain

Relação entre risco e medo de queda em idosas participantes de um projeto social / The relationship between the risk and fear of falling in older women participating in social project

Objetivo: Verificar a relação entre o risco e o medo da queda em idosas participantes de um projeto social. Métodos: Estudo transversal, realizado com 59 idosas participantes de um projeto social ofertado no município de Cianorte­PR. Para avaliar o medo de cair foi utilizada a FES-1-BRASIL. Para avaliação da mobilidade da marcha e risco de queda foi aplicado o teste Timed Up & Go (TUG). Para análise dos dados foi utilizado a estatística descritiva (frequência, percentual, média e desvio padrão), o teste de Kolmogorov-Smirnov, teste t de Student independente e a correlação de Pearson, sendo adotada a significância de p< 0,05. Resultados: Idosas apresentaram risco moderado a alto de cair. Ao analisar o medo de cair das idosas, observou-se o escore médio de 27,4 ± 6,91. Já ao avaliar a mobilidade e equilíbrio de idosos através do TUG, verificou-se que o tempo médio foi de 11,6 ± 2,9 segundos. As idosas mais jovens e que estavam há mais de três anos no projeto apresentaram menor medo de cair e menor risco de queda (p= 0,039 e p= 0,001, respectivamente). Foram encontras as seguintes correlações significativas (p< 0,05): medo de cair com tempo de participação no projeto (r= -0,42); risco de queda com a idade (r= 0,29) e medo de cair (r= 0,56). Conclusão: A partir dos resultados obtidos, conclui-se que a idade e o tempo de participação no projeto parecem ser fatores intervenientes no medo de cair e no risco de quedas das idosas. Ressalta-se que as idosas mais jovens e com maior tempo de participação no projeto apresentaram menor medo e risco de cair. Além disso, foi possível observar que quanto maior o risco de queda, maior o medo de cair.

Objective: To verify the relationship between risk and fear of falling in older women participating of social projects. Methods: Cross-sectional study, conducted with 59 older women participating in a social project offered by the city of Cianorte-PR. To assess the fear of falling, the FES-1-BRASIL was used. To assess gait mobility and risk of falling, the Timed Up & Go (TUG) test was applied. Descriptive statistics (frequency, percentage, mean and standard deviation), the Kolmogorov-Smirnov test, independent student's t test and Pearson's correlation were used for data analysis, with a significance of p< 0.05. Results: the older women had a moderate to high risk of falling. The analysis of the elderly women's fear of falling evidenced a mean score of 27.4 ± 6.91. Regarding mobility and balance, it was found that the average time to perform the TUG was 11.6 ± 2.9 seconds. Women under 70 years of age who had been in the project for more than three years had less fear and lower risk of falling (p= 0.039 and p= 0.001, respectively). The following significant correlations were found (p< 0.05): fear of falling with time of participation in the project (r= -0.42); risk of falling with age (r= 0.29) and fear of falling (r= 0.56). Conclusion: From the results obtained, we concluded that age and time of participation in the project seem to be intervening factors in the fear and risk of falling among the elderly women. It is noted that the women under 70 years of age and those with more extended participation in the social project had less fear and risk of falling. In addition, it was possible to observe that the he risk of falling is directly associated with the fear of falling.

Isolamento social durante a pandemia de COVID-19 aumenta o indicativo de sarcopenia e o comportamento sedentário em idosos brasileiros / Social isolation during the Covid-19 pandemic increases the indicator of sarcopenia and sedentary behavior in brazilians older adults

Objetivo: comparar se o indicativo de sarcopenia e comportamento sedentário aumentou durante o isolamento social devido à pandemia de COVID-19 em idosos brasileiros. Métodos: Estudo transversal realizado com 98 idosos de ambos os sexos, sendo 64 homens e 34 mulheres das regiões Sul e Sudeste do Brasil, e que estavam em isolamento social total ou parcial devido à pandemia de COVID-19 (junho a julho de 2020). Foram utilizados o SARC-F e o Questionário Internacional de Atividade Física (IPAQ), versão curta. A coleta de dados quantitativos ocorreu através de um formulário on-line disponibilizado pela Survey Monkey. Os dados foram analisados por meio dos testes Kolmogorov-Smirnov, Levene, t independente e dependente, e coeficiente de Spearman. Adotou-se significância quando p < 0,05. Resultados: as mulheres (p = 0,047) e os idosos que não praticavam exercício físico (p = 0,001), apresentaram maior tempo sentado após o início da pandemia. Os idosos mais novos (p = 0,002) e que reportaram estar praticando exercício antes do isolamento social (p = 0,006) apresentam menores escores indicativos de sarcopenia durante a pandemia. Os idosos apresentaram aumento nos indicativos de sarcopenia (p = 0,050) e no comportamento sedentário (p = 0,001) durante o período de isolamento social. Conclusão: o período de isolamento social devido à pandemia da COVID-19 provocou aumento no indicativo de sarcopenia e no comportamento sedentário das pessoas idosas.

Objective: to compare whether the indicative of sarcopenia and sedentary behavior increased during social isolation due to the COVID-19 pandemic in elderly Brazilians. Methods: Cross-sectional study conducted with 98 elderly people of both sexes, 64 men and 34 women from southern and southeastern Brazil, and who were in total or partial social isolation due to the COVID-19 pandemic (June to July 2020). The SARC-F and the International Physical Activity Questionnaire (IPAQ), short version, were used. The collection of quantitative data took place through an online form provided by Survey Monkey. Data were analyzed using the Kolmogorov-Smirnov, Levene, independent and dependent t tests, and Spearman's coefficient. Significance was adopted when p < 0.05. Results: women (p = 0.047) and the elderly who did not exercise (p = 0.001) had more time sitting after the onset of the pandemic. Younger elderly (p = 0.002) and those who reported having been exercising before social isolation (p = 0.006) had lower scores indicative of sarcopenia during the pandemic. The elderly showed an increase in sarcopenia indicatives (p = 0.050) and in sedentary behavior (p = 0.001) during the period of social isolation. Conclusion: the period of social isolation due to the COVID-19 pandemic caused an increase in the indicative of sarcopenia and in the sedentary behavior of the elderly.

Evaluación de los movimientos generales en niños prematuros para predicción de parálisis cerebral / Assessment of general movements in preterm infants as a predictor of cerebral palsy

La identificación temprana de la parálisis cerebral es aún en la actualidad un gran desafío para el sistema de salud en el mundo. Hubo grandes avances de la neonatología en disminuir la mortalidad, pero no así la morbimortalidad; la parálisis cerebral continúa siendo la secuela más común de todos los trastornos del desarrollo, especialmente entre quienes nacen prematuramente. La posibilidad de realizar detección precoz antes de los 5 meses de edad conlleva múltiples beneficios para el niño y su familia, ya que permite su incorporación muy temprana a tratamiento. En este trabajo describimos una herramienta con gran sensibilidad y especificidad conocida como evaluación de los movimientos generales de Prechtl y su posible complementación con aplicaciones tecnológicas para la detección temprana.

At present, the early identification of cerebral palsy still poses a major challenge for the health system worldwide. Great advances have been made in neonatology in reducing mortality, but not morbimortality. Cerebral palsy remains the most common sequela of all developmental disorders, especially among those born prematurely. The possibility of early detection before 5 months of age has many benefits for the child and their family, since it allows very early initiation of treatment. In this study, we describe a highly sensitive and specific tool known as Prechtl's assessment of general movements and its potential complementation with technological apps for early detection.

Acesso às práticas corporais/atividade física durante o ciclo da vida: relato de idosas aposentadas / Access to body practices/physical activity during the life cycle: report of retired elderly women

O objetivo foi verificar o acesso às práticas corporais/atividade física (PCAF) ao longo da vida de idosas aposentadas participantes de um grupo de PCAF. Trata-se de um estudo qualitativo com 16 mulheres idosas com idade entre 65 a 75 anos, selecionadas por conveniência, participantes de um grupo de PCAF de uma Unidade Básica de Saúde de Londrina, Paraná. As informações foram coletadas a partir de entrevistas com roteiro semiestruturado, conduzidas individualmente pelo profissional responsável pelo grupo. Os dados foram analisados por elementos da análise de conteúdo pelo sistema de categorias. Três categorias de análise foram consideradas: infância/adolescência; idade adulta; e terceira idade. Na infância/adolescência as mulheres relataram que não tiveram incentivo de seus pais, bem como não tiveram educação física na escola. Na fase adulta, a falta de tempo e de incentivo dos parceiros, além do desconhecimento de atividades ofertadas foram relatadas pelas mulheres. Somente a partir da terceira idade, especialmente após a aposentadoria, com a melhora da condição financeira e com o fato de terem maior tempo livre, as mulheres indicaram uma melhora no acesso, inclusive com a possibilidade da participação no grupo de PCAF. Em geral os resultados revelaram a dificuldade do acesso dessas mulheres às PCAF ao longo de suas vidas e reforçam a importância de ações e políticas públicas que busquem aumentar o incentivo e o acesso as PCAF ao longo da vida das mulheres

The objective was to verify the access to body practices/physical activity (BPPA) throughout the life of retired elderly women participating in a group of BPPA. This is a qualitative study with 16 elderly women aged between 65 and 75 years, selected for convenience, participants of a PCAF group at a Public Health Centre in Londrina, Brazil. The information was collected from interviews with a semi-structured script, which were conducted individually by the professional responsible for the group and analyzed from the content analysis by the category system. Three analysis categories were considered: childhood/adolescence; adulthood; and Old age. In childhood/adolescence, the women reported that they had no encouragement from their parents and had no physical education at school. In adulthood, lack of time and lack of encouragement from partners, in addition to the lack of knowledge of activities offered, were reported by women. Only from old age, especially after retirement, with the improvement of the financial condition and the fact of having more free time, the women indicated an improvement in the access to physical activity, including the possibility of participating in the PCAF group. In general, the results revealed the difficulty of these women's access to PCAF throughout their lives and reinforce the importance of public actions and policies that seek to increase incentives and access to PCAF throughout women's lives

Ambiente do bairro e da escola e sua associação com atividade física diária e uso de telas / Neighborhood and school environment and its association with daily physical activity and screen use

O objetivo deste estudo transversal foi analisar a associação entre ambiente construído no bairro e na escola e atividade física diária (AFD) e uso de telas diário (TD) entre estudantes de diferentes padrões de comportamentos. Participaram estudantes (9,1 ± 1,38 anos, 53,2% meninas) do 2º ao 5º ano de escolas públicas (n = 2.384) da cidade de Feira de Santana, BA. Atividades físicas e comporta-mentos sedentários foram avaliadas através de questionário online (Web-CAAFE) e utilizadas para definir os padrões de comportamentos por análise de cluster, segmentada por sexo. Ambiente cons-truído na escola (parquinho e espaços cobertos para atividades físicas) e no bairro (quadras esportivas, campos de futebol, parques e praças) foram as exposições. Os desfechos, AFD e TD, foram obtidos pelos somatórios dos relatos de um dia. Modelos de regressão binomial negativa, controlados por idade e escore-z de Índice de Massa Corporal, estimaram razões de prevalência (RP) e intervalos de confiança de 95% (IC95%). A AFD associou-se a praças entre meninas "jogadoras ativas" (RP = 1,35; IC95%: 1,09 - 1,68) e a Espaços cobertos para atividades físicas entre "sedentárias/executoras de tarefas domésticas" (RP = 0,86; IC95%: 075 - 0,97). Entre meninos "sedentários em atividades acadêmicas" a AFD associou-se a Campos de futebol (RP = 1,20; IC95%: 1,02 - 1,42) e TD a Parquinho (RP = 1,17; IC95%: 1,00 - 1,37). TD também foi associado a Espaços cobertos para atividade física entre "sedentários em telas" (RP = 1,28; IC95%: 1,04 - 1,57). AFD e TD de meninos e meninas com diferentes padrões de comportamento foram associados a diversos fatores do ambiente construído

The aim of this cross-sectional study was to analyze the association between the built environment at school and in the neighborhood and daily physical activity (DPA) and daily screen use (DS) among students with different behavioral patterns. Participants were students (9.1 ± 1.38 years, 53.2% girls) from the 2nd to the 5th year of public schools (n = 2,384), in the city of Feira de Santana, BA. Physical activities and sed-entary behaviors were assessed using an online questionnaire ( Web-CAAFE) and used to define behavioral patterns by cluster analysis, segmented by gender. Built environment at school (playground and covered spaces for physical activities) and in the neighborhood (sports courts, soccer fields, parks and squares) were the exposures variables. The outcomes, DPA and DS, were obtained by the sum the one-day reports. Mul-tiple negative binomial regression models, controlled for age and Body Mass Index z-score, were estimated prevalence ratios (PR) and 95% confidence intervals (95%CI). DPA was associated with squares among "active players" girls (PR = 1.35; 95%CI: 1.09 - 1.68) and with covered spaces for physical activities among "sedentary/Household chores performers" (PR = 0.86; 95%CI: 075 - 0.97). Among "sedentary in academic tasks" boys, DPA was associated with Soccer fields (PR = 1.20; 95%CI: 1.02 - 1.42) and DS with Play-ground (PR = 1.17; 95%CI: 1.00 - 1.37). DS was also associated with Covered spaces for physical activity among "sedentary on screen" (PR = 1.28; 95%CI: 1.04 - 1.57). DPA and DS of boys and girls with different behavior patterns were associated with several built environment factors

Describing physical activity in public open spaces in Brazil: Active City, Healthy City Program / Descrevendo a atividade física em espaços públicos abertos no Brasil: Programa Cidade Ativa, Cidade Saudável

This study aimed to describe the physical activity (PA) in public open spaces (POS) in a medi-um-sized city in Brazil. The System for Observing Play and Recreation in Communities (SOPARC) was applied to evaluate a representative sample of users in 10 POS which received actions from the Active City, Healthy City Program. The places were evaluated four days a week (Tuesday, Wednes-day, Saturday, and Sunday) at four times (8 am, 10 am, 2 pm, and 4 pm). The proportion of users by gender, age group, skin color, and PA level was compared between the POS using the chi-square test for heterogeneity in the STATA software (p<0.05). As main results, 32,768 scans were performed in 64 target areas and identified 8,634 individuals. The highest proportion of people were males (58%), adults (38%), with white skin color (97%), and in light or moderate PA (76%). Except for skin color, there was a significant difference in the proportion of all other variables between the POS (p < 0.05). In conclusion, the POS was more commonly used by men, adults, and people of white skin color for light and moderate PA. Based on the results, program managers could reallocate resources to increase utilization and PA at each place

O objetivo deste estudo foi descrever a atividade física (AF) em espaços públicos abertos (EPA) em uma cidade de médio porte do Brasil. O System for Observing Play and Recreation in Communities (SOPARC) foi utilizado para avaliar uma amostra representativa de frequentadores de 10 EPA que receberam ações do programa Cidade Ativa, Cidade Saudável. Os locais foram avaliados quatro dias da semana (terça-feira, quarta-feira, sábado, domingo) em quatro horários (8h, 10h, 14h, 16h). A proporção de frequentadores por sexo, faixa etária, cor de pele e nível de AF foi comparada entre os EPA pelo teste do qui-quadrado para heterogeneidade no software STATA (p < 0,05). Como resultados principais, foram realizados 32.768 scans em 64 áreas-alvo e 8.634 frequentadores foram identificados. Foi observada maior proporção de pessoas do sexo masculino (58%), adultos (38%), de cor de pele branca (97%) e em AF de intensidade leve ou moderada (76%). Com exceção da cor da pele, houve diferença significante na proporção das demais variáveis entre os EPA (p < 0,05). Em conclusão, os EPA são mais comumente utilizados por homens, pessoas adultas, de cor de pele branca e para a prática de AF de intensidade leve e moderada.

Public open spaces (POSs) are means to ensure one's right to recreation and health. The objective of this essay is to present reflections and evidence on how these spaces contribute to promoting physi-cal activity (PA). Understanding how to access (proximity/distance), quantity and diversity, and the surrounding and internal conditions of places (quality, structure, aesthetics, safety) can affect the use of POSs is imperative for public management actions. Thinking of POS use beyond PA by recog-nizing its social, economic, and cultural benefits can be fundamental to reduce inequalities regarding access to these places. POS-related actions and demands are intersectoral, multiprofessional, and interdisciplinary, thus requiring political, academic, and community involvement and commitment for PA promotion

Espaços públicos abertos (EPA) são equipamentos que promovem o direito à recreação e à saúde. O objetivo deste ensaio é apresentar reflexões e evidências sobre como esses espaços contribuem para a promoção da atividade física (AF). Compreender como o acesso (proximidade/distância), a quantidade e diversidade, as condições do entorno e internas dos locais (qualidade, estrutura, estética, segurança), podem afetar o uso dos EPA é fundamental para ações da gestão pública. Pensar o uso do EPA para além da prática de AF, reconhecendo seus benefícios sociais, econômicos e culturais pode ser fundamental para diminuir as iniquidades de acesso a esses locais. Ações e demandas relacionadas aos EPA são intersetoriais, multiprofissionais e interdisciplinares, necessitando com isso envolvimento e comprometimento político, acadêmico e comunitário, a fim de promover AF

Associação entre a função sexual, imagem corporal e autoimagem genital de idosas fisicamente ativas / Association between sexual function body image and genital self-image of old physically active

A sexualidade é uma necessidade básica que permanece com o envelhecimento e está relacionada com a função sexual bem como com as percepções de imagem corporal e genital. Este estudo tem como objetivo verificar a associação entre função sexual e imagem corporal e autoimagem genital de idosas fisicamente ativas. Estudo de natureza quantitativa explicativa e retrospectiva com 132 idosas de um núcleo de atividade física. Utilizou-se uma ficha de avaliação adaptada, Índice de Função Sexual Feminina (FSFI), Body Appreciation Scale (BAS) e o Female Genital Self-Image Scale (FGSIS). A amostra apresentou indicativos de disfunção sexual (FSFI=18,8±12,7) bem como uma boa imagem corporal (BAS=4,8±0,4) e autoimagem genital (FGSIS=25,4±3). A função sexual esteve correlacionada com a autoimagem genital (r=0,231, p=0,008), e com a imagem corporal (r=0,978, p=0,000) e entre a autoimagem genital e a imagem corporal (r=0,389, p=0,000). Ao separar os domínios da função sexual, todos apresentaram correlação com a imagem corporal. Com a autoimagem genital, apenas a satisfação não apresentou correlação (r=0,131 e p=0,132). É relevante investigar os aspectos relacionados a sexualidade dos idosos pois podem interferir na qualidade de vida e bem-estar físico, psicológico e social.(AU)

Sexuality is a basic need that remains with aging and is related to sexual function as well as perceptions of the body and genital image. This study aims to verify the association between sexual function and body image and genital self-image of physically active elderly women. Quantitative, explanatory, and retrospective study with 132 elderly women from a physical activity center. An adapted evalua- tion form, Female Sexual Function Index (FSFI), Body Appreciation Scale (BAS), and the Female Genital Self-Image Scale (FGSIS) were used. The sample showed signs of sexual dysfunction (FSFI = 18.8 ± 12.7) as well as a good body image (BAS = 4.8 ± 0.4) and genital self-image (FGSIS = 25.4 ± 3). Sexual function was correlated with genital self-image (r = 0.231, p = 0.008), and with body image (r = 0.978, p = 0.000) and between genital self-image and body image (r = 0.389, p = 0.000). When separating the domains of sexual function, all showed a correlation with body image. With genital self- image, satisfaction was not correlated (r = 0.131 and p = 0.132). It is relevant to investigate aspects related to the sexuality of the elderly as they can interfere with the quality of life and physical, psychological, and social well-being.(AU)

Association between non school sedentary time and myopia among primary and secondary school students with different levels of physical activity / 中国学校卫生

Objective@#To analyze the association between non-school sedentary time and myopia among primary and secondary school students with different levels of physical activity, so as to provide data for precise measures to prevent and control myopia.@*Methods@#From September to December 2019, stratified cluster sampling was used to select 7 872 primary and secondary students in grades 4 to 12, middle and high school students from Hefei, Suzhou, Chizhou and Wuhu Cities in Anhui Province. Face-to-face questionnaires and vision examinations were conducted to collect demographic information, physical activity time, sedentary study time and visual health status. Potential categories were analyzed for different types of physical activity time, and Logistic regression was used to assess the relationship between non-school sedentary time and myopia at different levels of physical activity.@*Results@#A total of 2 976 primary and secondary school students were found with high physical activity levels and 4 896 primary and secondary school students with low physical activity levels. The proportion of low physical activity was higher in girls than in boys (68.7% vs . 55.6%), and the differences were statistically significant ( χ 2=143.97, P <0.01). The overall screening myopia rate was 48.2%, with statistically significant differences among female students (53.0%) compared with male students (43.3%), urban students ( 51.8 %) compared with rural students (44.5%), and longer non-school sedentary time students (60.6%) compared with average (45.1%) and shorter (42.1%) non-school sedentary time students, and the differences were statistically significant ( χ 2=73.15, 41.96 , 161.74, P <0.01). Adjusting for confounders such as residence, grade, gender, age, father s education, mother s education, and body mass index (BMI), multivariate Logistic regression analysis revealed that prolonged after-school sedentary study was positivety correlated with myopia among primary and secondary school students of low physical activity levels ( OR=1.52, 95%CI=1.27-1.83, P <0.01), and there was no statistical association between after-school sedentary time and myopia in primary and secondary school students with high physical activity levels ( P >0.05).@*Conclusion@#Attention should be paid to non-school sedentary time for primary and secondary school students with low physical activity levels. And students who spend a lot of time sitting outside of school should be encouraged to maintain high physical activity levels to reduce the risk of myopia.

Association between depression and anxiety symptoms with physical activity among rural returning adolescents / 中国学校卫生

Objective@#To understand the symptoms of depression and anxiety among rural returning adolescents and to analyze their association with physical activity related factors, so as to provide reference for interventions targeting depression and anxiety symtoms in the population.@*Methods@#From April to June 2020, 3 495 middle school students were selected from 6 counties and districts of Shangrao City by random cluster stratified sampling sampling. The Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) were used to evaluate the depressive and anxiety symptoms among middle school students. The International Physical Activity Questionnaire was used to assess their physical activity levels during the past week. Chi square test and Logistic regression analysis were used to determine the strength of the association between depression and anxiety symptoms and physical activity related factors in returning and non returning adolescents as well as the overall population.@*Results@#Univariate analysis showed significant differences in the prevalence of depressive and anxiety symptoms between rural returning and non returning adolescents and the overall population in terms of "type of school" "family economic situation" "parental occupation" "number of sports classes per week" and "level of physical activity per week" ( χ 2=78.21, 16.56, 135.44, 107.75, 7.10, 8.62; 97.94, 24.26 , 124.07, 90.36, 9.60, 8.34, P <0.05). Multivariate regression analysis showed a correlation between the occurrence of depression and the number of sports classes per week for rural returning and non returning adolescents and the overall population (number of sports classes per week for non returning was 2 times, OR=1.22, 95%CI =1.01-1.49; returning adolescents for 1 time, OR=1.85, 95%CI =1.06-3.23; the overall population for 1 time, OR=1.34, 95%CI =1.01-1.77 and 2 times, OR=1.20, 95%CI =1.01-1.43, P <0.05). There was a correlation between anxiety symptoms and the number of sports classes per week for returning adolescents (number of sports classes per week for returning adolescents was 1 time, OR=2.10, 95%CI=1.21-3.63, P < 0.05 ).@*Conclusion@#A low frequency of weekly sports classes may be a risk factor for depressive or anxiety symptoms in rural and returning adolescents. Rural primary and secondary schools should appropriately increase the number of physical education courses or arrange sports extended classes to promote the development of adolescent mental health.

Objective@#To explore effects of aquatic exercise on lipid metabolism, body composition and peripheral blood Irisin level in obese middle school students, so as to provide reference for exercise and weight loss practice of obese children and adolescents.@*Methods@#Twenty six male students, recruited to participate in the summer youth swimming(weight loss) camp in Rudong County Jiangsu Province, were divided into non obese( n =12) and obese ( n =14) group. And t test method was applied for a statistical analysis of their ipid metabolism, body composition and peripheral blood irisin level before and after 8 week aquatic exercise.@*Results@#The high density lipoprotein cholesferol(HDL-C) in the obese group was significantly lower than nonobese group, which were (1.34±0.12) mmol/L and (1.51±0.21) ng/mL, respectively, and the differences were of statistical significance( t=2.81, 6.39 , 8.96, 12.69, -2.72 , P <0.05). After intervention, body weight, body mass index (BMI), fat mass(FM), body fat percentage(BF%) of obese male middle school students decreased from (77.31±8.26)kg, (28.02±1.67)kg/m 2, (25.16±3.59)kg and (32.65±3.90)% to (72.37±7.19)kg, (26.15±1.21)kg/m 2, (21.71±2.66)kg and (30.14±3.61)%，muscle mass(MM) increased from (25.09±3.41)kg to (26.76±3.55)kg. TC, TG, LDL-C contents decreased from (4.69±0.48, 1.31±0.26, 2.74±0.42)mmol/L to (4.28±0.42, 1.14±0.14, 2.36±0.36)mmol/L, HDL-C increased from (1.34±0.12)mmol/L to (1.47±0.11)mmol/L, and serum Irisin concentrations lowered from (192.17±23.27) ng/mL to (164.15±21.69)ng/mL of obese male middle school students. Serum Irisin concentrations of the obese positively related to BMI( r =0.68), FM( r =0.87) and BF( r =0.64), as well as TC( r =0.61), TG( r =0.86), LDL-C( r =0.85), but negatively associated with HDL-C( r =-0.63). A positive relations existed between different value of serum Irisin concentrations and BMI, FM before and after intervention of obese students( r =0.58, 0.53)( P <0.05).@*Conclusion@#Obese middle school students may be resistant to Irisin. 8 weeks of aquatic exercise can improve fat metabolism, body composition and serum Irisin levels of obese junior middle school students effectively. The qualified obese children and adolescents can use aquatic exercise as an intervention measure to control body weight reasonably and improve lipid metabolism.
