Effectiveness of comprehensive sexuality education curriculum on improving hostile and benevolent sexism among university students / 中国学校卫生

Objective@#To explore the effectiveness of a comprehensive sexuality education (CSE) curriculum on university students hostile and benevolent sexism, so as to provide a reference for evaluating the effects of CSE on reducing ambivalent sexism.@*Methods@#From September 2018 to January 2019, 165 university students from a university in Beijing were recruited using convenience sampling for a 5 month of CSE curriculum (36 sessions, 2 sessions per week, 45 min per session), including CSE and gender studies, sexual physiology and health, gender and gender roles, gender bias, intimate relationships and gender bias, gender based violence and gender bias, culture and gender bias, and gender and power. Students who took CSE curriculum were included in the intervention group ( n =97) and students from the same university who had not taken CSE curriculum were included in the control group ( n =68). Using the Ambivalent Sexism Inventory, both groups of university students were surveyed before and after the curriculum to analyze the effectiveness of the CSE curriculum. Chi -square test, ANOVA，cluster analysis and Kruskal Wallis test were used for statistical analysis.@*Results@#After the CSE curriculum, both hostile and benevolent sexism scores were lower in the intervention group (2.21±0.76, 2.36±0.68) than in the control group (2.81±0.61, 3.03±0.60) ( F =17.24, 33.26), and pre test scores were higher in the intervention group (2.64±0.67, 2.88±0.68) ( F =45.62, 66.93) ( P <0.01). On both hostile and benevolent sexism, female students scores (2.46±0.72, 2.65±0.70) were lower than male students scores (2.86±0.59, 3.09± 0.69 ) ( F=11.02, 14.20, P <0.01). Comparison of the curriculum effectiveness of hostile and benevolent sexism among clustered groups showed that the difference in hostile sexism scores was higher in the inconsistent type [0.63(0.25, 1.25)]than in the more consistent type [0.38(-0.16, 0.88)] and the lower consistent type [0.38(0.06, 0.63)] ( H=8.71, P <0.05); and the difference in benevolent sexism scores was higher in the more consistent type [0.75(0.53, 1.22)] than in the less consistent type [0.38(0.09, 0.88 )] and inconsistent type [0.38(-0.13,0.63)] ( H=10.82, P <0.05).@*Conclusions@#CSE can improve hostile and benevolent sexism in university students with sex and type differences. Attention should be paid to CSE curriculum to improve ambivalent sexism among university students with a view to fostering their awareness of gender equality.

Intervention effects of moderate and high intensities of classroom physical activity on cardiorespiratory fitness and executive function among junior grade one students in Tibetan / 中国学校卫生

Objective@#To explore the intervention effect of different intensity of classroom physical exercise on cardiorespiratory fitness and executive function of Tibetan first grade students at high altitude, so as to provide reference for improving the level of cardiorespiratory fitness and executive function of Tibetan adolescents.@*Methods@#From September to December 2020, 184 Tibetan students from five first grade classes in a middle school in Lhasa, Tibet, were randomly assigned into a control group (81 students in two classes) and an intervention group (103 students in three classes). Both groups followed the same teaching programme, but the intervention group received 36 sessions of moderate to high intensity classroom physical activity, one session per day, Monday,Wednesday and Friday, for 12 weeks. Before and after the intervention, cardiorespiratory fitness and executive function were tested by 20m round trip running and Flanker s experimental paradigm, 2-back s experimental paradigm, and More odd shifting experimental paradigm for inhibitory control, refreshing memory, and switching flexibility, and the results were analysed by analysis of covariance (ANCOVA) to compare the results of the pre and post intervention periods.@*Results@#The maximum oxygen uptake (VO 2max ) of Tibetan first grade students in the intervention group increased by 2.25 mL/(kg〖WW）〗·〖WW(〗min) compared with the control group after the intervention ( t =-3.89, P <0.01); the response time of the inhibitory function was reduced by 4.40 ms, that of the refreshing function by 196.06 ms, and that of the switching function by 92.72 ms in the intervention group compared with the control group ( t =2.98, 4.82 ,3.21, P <0.05).@*Conclusion@#The 12 week moderate to high intensity classroom physical activity intervention has different degrees of improvement effects on cardiorespiratory fitness and executive function in Tibetan adolescents.

Intervention effect of 12 week spinal health gymnastics on high and low shoulder exercise in adolescents / 中国学校卫生

Objective@#To explore the intervention effect of 12 week spinal health exercise on adolescents high and low shoulders, in order to provide empirical evidence for exploring simple and feasible measures to intervene.@*Methods@#In February 2023, 60 high and low shoulder students from a vocational high school in a certain county of Luzhou City were randomly selected as the research subjects by convenient sampling method. Paired sampling was used to randomly divide participants into an intervention group and a control group with 30 students each group. The intervention group received spinal health gymnastics intervention during 12 weeks of morning exercises and large break exercises for twice a day, with two groups each time; the control group maintained their previous morning exercises and large break exercises. A follow up study was conducted on the height difference between the left and right shoulder peaks of the intervention group and the control group students before intervention, after 12 weeks intervention, at 4 weeks post intervention. The t-test was used to analyze the changes in shoulder peak height difference between the intervention group and the control group.@*Results@#Before intervention, there was no statistically significant difference in the height of the left and right shoulder peaks between the intervention group [(2.50±1.19)cm] and the control group [(2.49±1.20)cm] adolescents ( t=0.05, P > 0.05). After 12 weeks of intervention, the difference in shoulder height between the left and right sides of adolescents in the intervention group decreased, compared to that before intervention [(1.43±1.15, 2.50±1.19)cm], while the control group increased compared to that before intervention [(2.58±1.19, 2.49±1.20) cm], and the differences were both statistically significant ( t= -78.17 , 20.15, P <0.05). At 4 weeks post intervention, there was no statistically significant difference in the height of the left and right shoulder peaks between the intervention group [(1.44±1.15)cm] and the control group [(2.59±1.18)cm] compared to 12 weeks after the intervention ( t=1.80, 1.05, P >0.05). The intervention group [(2.49±1.26, 2.52±1.16) (1.43±1.21, 1.44±1.13) (1.44±1.21, 1.45±1.14)cm] and the control group [(2.45±1.24, 2.52±1.20) (2.55±1.24, 2.61±1.18) (2.55±1.22, 2.62±1.18)cm] showed no statistically significant difference in the height of the left and right shoulder peaks between males and females before intervention, after 12 weeks of intervention, and after stopping intervention for 4 weeks ( t =-0.08, -0.03, -0.02; -0.15, -0.12, -0.15, P >0.05).@*Conclusions@#Spinal health gymnastics has a good effect on correcting high and low shoulders in adolescents. Spinal health gymnastics should be promoted on campus to promote adolescent posture health.

Effects of comprehensive intervention on 24 h activity behavior among obese students in vocational colleges / 中国学校卫生

Objective@#To explore the effects of comprehensive intervention measures targeting physical activity, sedentary, sleep and other behaviors on 24 h activity behavior of obese students in vocational colleges, so as to provide a more tailored empirical basis for intervening obese students in vocational colleges.@*Methods@#A quasi experimental design using parallel controlled, randomized grouping was conducted from January to March 2023. A total of 79 first year obese students from a vocational college in Wuxi City were selected as the intervention group (41 students) and the control group (38 students). From April to June, 2023, the control group received no intervention, while the intervention group adopted an information based and behavioral intervention approach to comprehensively intervene in 24 h physical activity, sedentary, sleep and other behaviors (120 minutes each day for 8 weeks).Wherein, information based intervention mainly used paper leaflets and social and learning software to accurately push intervention information, and behavioral intervention mainly concentrated 1 hour of physical exercise and multiple activity behavior requirements every day with the triaxial accelerometer to feedback the objective data of physical activity. Subsequently, from June to July, 2023, a one week post test and follow up survey were conducted respectively.Bouchard diary in physical activity, Weekly questionnaire and triaxial accelerometer were used to record the 24 h activity behavior of both groups of students. T-test and repeated measurement analysis of variance were used to compare the differences of 24 h activity component index time between two groups before and after intervention and examine the changes within each group.@*Results@#Before and after intervention, there was no significant difference in the time of each component index of 24 h activity behavior in the control group. However, repeated measures analysis of variance between the intervention group and the control group revealed statistically significant interaction differences in physical activity, sedentary behavior, sleep and other index time were statistically significant(pre-test and post test: F =6.45, 4.66 ,7.21,7.88; pre-test,post-test and follow up test: F =5.37,5.12,5.43,5.29; P <0.01). During the followup period, compared with the post-test data [(313.25±54.15, 601.88±65.47, 462.83±42.86, 61.92±18.53)min/d], the time of each component (physical activity, sedentary behavior, sleep, other) of the 24 h activity behavior of students in the intervention group rebounded [(298.52± 60.27 , 613.69±68.55, 442.33±45.26, 85.28±20.57)min/d], but it was better than the pre-test data [(230.45±67.42, 720.32±105.63, 369.78±32.31, 119.29±22.17)min/d], and the difference was statistically significant( F =42.46,39.45,33.41,59.43, P <0.01). During the intervention period, the physical activity, sedentary and sleep duration indicators of the intervention group students showed fluctuating patterns in the 4th and 5th weeks.@*Conclusions@#The comprehensive intervention on 24 h activity behavior among obese students in vocational colleges shows significant effectiveness, but its sustainability is insufficient. Considering the characteristics of obese students in vocational colleges, personalized intervention measures should be provided to increase physical activity and sleep time and reduce static activity time, in order to promote students to develop a healthy lifestyle.

The practice of physical exercise in the context of cognitive compromise and neuro-muscular interactions in the care of the elderly / Prática do exercício físico no comprometimento cognitivo e intercorrências neuromusculares na atenção ao idoso: uma revisão sistemática

Objective: to investigate the influence of physical exercise in the context of cognitive compromise of the elderly, and the exercise programmes of greater impact in the motor response and neuromuscular adaptations. Method: a systematic review was developed in the Pubmed/MEDLINE, Scopus, LILACS, SPORTDiscus and Embase databases. The PRISMA 2020 checklist and bias risk analysis were applied using the Cochrane handbook scale for the systematic review of interventions (Version 5.1.0). Domains in table 8.5.d. Results: 21 studies were included in the qualitative analysis. The regular practice of physical exercise causes a series of positive neuromuscular adaptations in the elderly. These adaptations are related to increases in muscle mass, strength and power, favouring cognitive and motor capacity. The change in lifestyle of the elderly has a significant impact, and 30% of the ageing process is considered natural and caused by sensory, mental and physical factors and a loss of self-control, but 70% depends absolutely on the individual lifestyle. Conclusion: The present study suggests a programme composed of combined strength, resistance and aerobic exercises. Such exercises cause increases in neurotrophic, vascular and growth factors, as well as promoting cognitive, mood and quality of life improvements during ageing. Thus, the implementation of an exercise programme involving plyometrics and greater intensities of resistance training (equal or greater to 60% of 1-MR) and an adequate and progressive volume (equal or greater to three 30-40-minute sessions per week), appears to promise improved cognitive and psychomotor outcomes in old age (AU).

Objetivo: investigar a influência do exercício físico no comportamento cognitivo dos idosos e os programas de exercícios de maior impacto na resposta motora e adaptações neuromusculares. Método: desenvolveu-se uma revisão sistemática nas bases de dados Pubmed/MEDLINE, Scopus, LILACS, SPORTDiscus e Embase. Utilizou-se o PRISMA 2020 e análise de risco de viés através da escala Cochrane handbook para revisões sistemáticas de inter-venções (Versão 5.1.0). Domínios da tabela 8.5.d Resultados: 21 estudos foram incluídos para análise qualitativa. A prática regular de exercício físico desencadeia uma série de adaptações neuromusculares positivas em pessoas idosas. Essas adaptações estão relacionadas ao aumento da massa, força e potência muscular, favorecendo a capa-cidade cognitiva e motora. A mudança no estilo de vida do idoso apontou impacto significativo, e 30% do processo de envelhecimento é considerado natural e causado por fatores sensoriais, mentais, físicos e perda do autocontrole. No entanto, 70% dependem impreterivelmente do estilo de vida individual. Conclusão: O presente estudo sugere um programa composto por exercícios combinados de força, resistência e aeróbicos. Tais exercícios promovem o aumento dos fatores neurotróficos, vascular e de crescimento, além de promover melhorias cognitivas, de humor e qualidade de vida ao envelhecer. Para tanto, a implementação de um programa de exercícios que envolva a plio-metria e um treinamento resistido com intensidades mais altas (igual ou superior a 60% de 1-RM) e um volume adequado e progressivo (igual ou superior a 3 sessões de 30-40 minutos por semana), parece ser promissor aos melhores desfechos cognitivos e psicomotores na terceira idade (AU).

El objetivo: investigar la influencia del ejercicio físico en el comportamiento cognitivo de las personas mayores y los programas de ejercicio con mayor impacto en la respuesta motora y adaptaciones neuromusculares. Método: se realizó una revisión sistemática en las bases de datos Pubmed/MEDLINE, Scopus, LILACS, SPORTDiscus y Embase. Se utilizó el PRISMA 2020 y el análisis de riesgo de sesgo mediante la escala del manual Cochrane para revisiones sistemáticas de intervenciones (Versión 5.1.0). Dominios en la tabla 8.5.d Resultados: Se incluyeron 21 estudios para el análisis cualitativo. La práctica regular de ejercicio físico desencadena una serie de adaptaciones neuro-musculares positivas en las personas mayores. Estas adaptaciones están relacionadas con el aumento de la masa muscular, la fuerza y la potencia, favoreciendo la capacidad cognitiva y motora. El cambio en el estilo de vida de los ancianos mostró un impacto significativo, y el 30% del proceso de envejecimiento se considera natural y causado por factores sensoriales, mentales, físicos y pérdida de autocontrol. Sin embargo, el 70% depende absolutamen-te del estilo de vida individual. Conclusión: El presente estudio sugiere un programa compuesto por ejercicios combinados de fuerza, resistencia y aeróbicos. Dichos ejercicios promueven el aumento de factores neurotróficos, vasculares y de crecimiento, además de promover mejoras cognitivas, anímicas y de calidad de vida en el enveje-cimiento. Por lo tanto, la implementación de un programa de ejercicios que involucre ejercicios pliométricos y de fuerza con intensidades más altas (igual o mayor al 60% de 1-RM) y un volumen adecuado y progresivo (igual o mayor a 3 sesiones de 30-40 minutos a la semana) ), parece ser prometedor para mejores resultados cognitivos y psicomotores en la vejez (AU).

Direito à saúde, tratamentos experimentais e indústria farmacêutica: breves anotações / Right to health, experimental treatments and pharmaceutical industry: brief notes / Derecho a la salud, tratamientos experimentales y industria farmacéutica: brevesnotas

Objetivo: compreender o excesso de judicialização no Brasil e buscar algumas justificativas que levaram ao estado da arte. Metodologia: utilizou-se o método de pesquisa indutivo, realizando um levantamento bibliográfico e análise documental, com base em dados divulgados pelo Conselho Nacional de Justiça e, de forma complementar, em dados extraídos do sítio institucional da Agência Nacional de Saúde Suplementar. Resultados: a judicialização da saúde tem apresentado um caráter predominantemente individual, o que agrava o alcance da macrojustiça e do atendimento da coletividade. Além disso, as dificuldades estruturais do Sistema Único de Saúde tornam-se cada vez mais evidentes. Observa-se que a judicialização da saúde pode ser perversa do ponto de vista do excesso de concessão de tutelas de urgência, da prioridade da justiça individualizada e do destaque da microjustiça; elementos que prejudicam o funcionamento do sistema de saúde como um todo. Conclusão: a indústria farmacêutica apresenta intensa participação no processo de incorporação de medicamentos. No entanto, a complexidade e demora das etapas procedimentais da incorporação dessas novas tecnologias, não raro, resultam em demandas judiciais que derivam decisões polêmicas e nem sempre acertadas. Todo esse desenho acaba por desencadear pressão no órgão competente de incorporação, incompreensões sobre o funcionamento do SUS e fortalecimento da microjustiça.

Objective: to understand the excess of judicialization in Brazil and seek some justifications that led to the state of the art. Methods: an inductive research method was used, which involved conducting a bibliographic survey and documentary analysis of data released by the National Council of Justice and, in addition, data extracted from the institutional website of the National Supplementary Health Agency. Results: the judicialization of health has presented a predominantly individual aspect, which aggravates the reach of macrojustice and community care. In addition, the structural difficulties of the Unified Health System become increasingly evident. The judicialization of health can be perverse from the point of view of the excess of granting emergency guardianships, the priority of individualized justice, the prominence of microjustice; elements that undermine the functioning of the health system as a whole. Conclusion: the pharmaceutical industry plays an intense role in the drug incorporation process. However, the complexity and delay in the procedural stages of incorporating these new technologies often result in legal demands that result in controversial decisions that are not always correct. This entire design ends up triggering pressure on the competent incorporation body, misunderstandings about the functioning of the SUS and strengthening microjustice.

Metodología: se utilizó el método de investigación inductivo, realizando un levantamiento bibliográfico y análisis documental, con base en datos divulgados por el Consejo Nacional de Justicia y, de forma complementaria, en datos extraídos del sitio web institucional de la Agencia Nacional de Salud Complementaria. Resultados: la judicialización de la salud ha presentado un carácter predominantemente individual, lo que agrava el alcance de la macrojusticia y de la atención de la colectividad. Además, las dificultades estructurales del Sistema Único de Salud son cada vez más evidentes. Se observa que la judicialización de la salud puede ser perversa desde el punto de vista de la concesión excesiva de tutelas de urgencia, de la prioridad de la justicia individualizada y del énfasis en la microjusticia; elementos que perjudican el funcionamiento del sistema de salud em su conjunto. Conclusión: la industria farmacéutica juega un papel intenso en el proceso de incorporación de medicamentos. Sin embargo, la complejidad y demora en las etapas procesales de incorporación de estas nuevas tecnologías derivan muchas veces en exigencias legales que derivan en decisiones controvertidas y no siempre correctas. Todo este diseño termina provocando presiones sobre el órgano constitutivo competente, malentendidos sobre el funcionamiento del SUS y fortalecimiento de la microjusticia.

School 1 conducted online and offline parental health education ( n =111), while school 2 exclusively conducted offline health education activities, representing the traditional intervention group ( n =122). Students from both schools underwent monitoring through wearable behavior tracking tools, with feedback reports provided (eye distance, eye duration, ambient light, and outdoor exposure time). Both schools relied on activities to carry out health education interventions, and organized the distribution of promotional materials and display boards. The intervention group also established WeChat groups to conduct online "Healthy Parents Action" (answering and providing feedback on health knowledge related to myopia prevention and control, myopia prevention and control, science popularization, etc. raised by parents). Evaluation criteria included myopia rates, post dilation refractive error, and axial length, with a tracking period of two years (from 2021 to 2023). Additionally, the study collected refractive parameters from non myopic students who did not participate in wearable tool monitoring in the 12 classes across the two schools.@*Results@#The baseline results indicated that there were no significant differences between the two groups in terms of refractive parameters and wearable tool monitoring results (including screen time, viewing distance, outdoor exposure time, and homework light exposure)( t/Z/χ 2=1.94,1.17,0.58,0.40,0.80,0.69,0.32, P >0.05). After a two-year follow up, in the first and second year, the myopia rate of the online Healthy Parents Action group (11.4%, 29.7%) were lower than that of the traditional group (26.2%, 50.9%), and the degree of refractive change in the intervention group [0.63(0.38,1.19)D] was lower than that of the traditional group [0.91(0.40,1.50)D], and all the differences were statistically significant( χ 2/ Z =4.93，10.37，2.29， P <0.05). However, there were no significant differences ( P >0.05) in axial length changes between the two groups over the twoyear intervention period. Nevertheless, in the second year, the axial length change in the traditional group [0.35(0.20,0.65)mm] was lower than that in the natural observation group [0.55(0.30,0.75)mm], and this difference was statistically significant ( Z =1.92, P <0.05).@*Conclusions@#Online and offline myopia prevention and control health education can effectively reduce myopia rates. The intervention mode combining wearable behavior monitoring tools with online health education may have better effects, but further large sample and multi center studies are needed to provide additional evidence and confirmation.

Effects of a ketogenic diet combined with resistance training on body composition and glucolipid metabolism in the obese and female college students / 中国学校卫生

Objective@#To investigate the effects of a ketogenic diet (KD) alone and in combination with resistance training (KD+RT) on body composition and glucolipid metabolism of obese and female college students, and to provide a theoretical basis for the application of KD+RT in obese patients.@*Methods@#Totally 45 obese and female college students in Wuyi University were recruited and randomly divided into KD group ( n =23) and KD+RT group ( n =22) in September 2021. After received training for 4 weeks, the changes of body composition and glucose and lipid metabolism of obese and female college students were compared before and after intervention.@*Results@#Both a 4 week KD and KD+RT led to decreases in weight, BMI, body fat mass, body fat percentage, waist to hip ratio, visceral fat area of obese female college students ( t =16.19, 16.21, 12.42, 7.99, 2.10, 6.37; 18.82, 18.02, 17.80, 10.72, 3.41, 7.59, P <0.01). The change of muscle mass was decreased in KD group( t=4.12, P <0.01), but there was no statistically significant difference in KD+RT group( P >0.05). Both a 4 week KD and KD+RT significantly reduced the levels of the fasting blood glucose, fasting insulin, glycosylated hemoglobin and triglyceride (TG) of obese female college students ( t =10.15, 8.94 , 6.94, 7.63; 9.23, 12.75, 9.85, 9.09, P <0.01), and increased the high density lipoprotein (HDL) level( t =-7.36, -5.22, P <0.01). However, only KD+RT group had a significant decrease in the level of LDL ( t =5.27, P <0.01), and there was no significant change in the level of TC both groups ( P >0.05). After the intervention, there was no statistically significant difference between the KD+RT group compared to the KD group ( P >0.05), except for a significant decrease in triacylglycerol ( t =2.51, P < 0.05 ).@*Conclusion@#Both a short term KD and KD+RT show beneficial changes in body composition and glucolipid metabolism in obese female college students. However, the KD+RT is superior to a KD in maintaining muscle mass and reducing the effects of lipid metabolism.
