RESUMEN
BACKGROUND: Cardiorespiratory fitness (CRF) plays a significant role in health and academic performance in youth. The purpose of this study was to examine the longitudinal relationship between CRF and academic performance from fifth to eighth grade among a large, diverse, and state-wide cohort of students, and to determine the extent to which the relationship between change in CRF and academic performance is moderated by poverty status. METHODS: CRF and academic performance data were obtained for a retrospective state-wide cohort of 11,013 students with baseline (fifth grade, school year 2015-2016) and follow-up (eighth grade, school year 2018-2019) data. Analysis of covariance was used to examine the association between changes in CRF over a 3-year follow-up period and eighth grade academic performance. RESULTS: After adjusting for covariates, change in CRF and poverty status were positively and significantly associated with eighth grade academic performance. Poverty status did not significantly moderate the association between changes in CRF and academic performance. CONCLUSIONS: Schools should prioritize evidence-based policies and programs that optimize students' access to high quantity and quality physical activity throughout the school day. Such efforts can improve and maintain student CRF and thus academic performance outcomes.

Acute and overuse injuries are a common experience for artistic gymnasts; however, this population has unique needs when returning to their sport after an injury due to the technical demands imposed during gymnastics. We reviewed the current literature regarding return to play (RTP) in artistic gymnasts and developed four goals: 1) to define the guiding principles used to determine RTP in sports, 2) to identify factors that affect recovery progression among gymnasts, 3) to determine how different injury types affect RTP protocols, and 4) to create structured RTP protocols specific to gymnasts based on sex and body part injured. By establishing these guidelines, we hope to provide guidance to medical providers through a standardized approach for returning gymnasts to their sport.

PURPOSE: To examine the association between objectively measured CRF and physical and mental components of HRQoL in a Uruguayan cohort at risk for developing CVD. METHODS: Patient data records from 2002-2012 at the Calidad de Vida Center were examined. To assess CRF, participants performed a submaximal exercise test. During the evaluation, participants also completed the SF-36, a HRQoL measure comprised of eight dimensions that are summarized by physical and mental component scores (PCS and MCS, respectively). ANCOVA was used to examine the relationship between HRQoL dimensions and CRF. Logistic regression was then used to compare the odds of having a HRQoL component score above the norm across CRF. All analyses were performed separately for males and females with additional stratified analyses across age and BMI conducted among significant trends. RESULTS: A total of 2,302 subjects were included in the analysis. Among females, a significant relationship was observed between CRF and vitality, physical functioning, physical role, bodily pain, and general health dimensions. However, for males the only dimension found to be significantly associated with CRF was physical health. After adjusting for potential confounders, a significant linear trend (p<0.001) for PCS scores above the norm across CRF levels was observed for females only. CONCLUSION: Among females with one or more risk factors for developing CVD, higher levels of CRF were positively associated with the vitality and physical dimensions of HRQoL, as well as the overall PCS. However, among males the only dimension associated with CRF was physical functioning. Future studies should examine this relationship among populations at risk for developing CVD in more detail and over time.

OBJECTIVE: To estimate the prevalence of high-risk sexual behaviours among Jamaican adults and evaluate associations with sociodemographic and religious factors. METHODS: We performed a cross-sectional study, using a nationally representative sample of Jamaicans, 15-74 years old. Participants completed an interviewer-administered questionnaire including questions on sexual activity, sociodemographic factors and religious practice. Having two or more sexual partners in the past year, non-use of condoms among persons with multiple partners and a history of previous sexually transmitted infection (STI) were the high-risk characteristics considered in the analysis. We obtained crude and category specific prevalence estimates for high-risk behaviour and estimated odds ratios for association with sociodemographic and religious factors. RESULTS: Data from 2833 participants who reported on sexually activity were analysed. Approximately 25% (95% CI 22, 27) of Jamaican adults had two or more sexual partners in the past year while 15% (95% CI 13, 17) had a past history of an STI. Approximately 6% (95% CI 5, 7) of persons with multiple partners did not use condoms during sexual intercourse. Overall, 32% (95% CI 30, 35) had any one of the three high-risk characteristics (male, 48%; female, 17%, p < 0.001). Being married, active religious practice and weekly attendance at religious meetings were associated with lower odds of high-risk sexual behaviour while being in a visiting relationship was associated with higher odds of high-risk behaviour CONCLUSION: A third of Jamaicans reported sexual practices that increase their risk of HIV infection. High-risk sexual behaviour was more common among men. Being married and weekly attendance at religious services were associated with lower odds of high-risk behaviour

OBJECTIVE: To evaluate the effect of acupuncture combined with physiotherapy in comparison with acupuncture and physiotherapy performed alone in different parameters; pain intensity, muscle tension, functional disability and muscle strength in the treatment of tension neck syndrome (TNS). DESIGN: A prospective, comparative clinical trial. SETTING: Acupuncture and Rehabilitation Department. BACKGROUND: TNS can occur in computer users. Acupuncture has been one alternative treatment in physiotherapeutic rehabilitation of musculoskeletal disorders. SUBJECTS: Forty-six patients with TNS. INTERVENTIONS: Patients were allocated into three groups: Group-1 received physiotherapy (therapeutic exercises) combined with acupuncture; Group-2, acupuncture alone, and Group-3, physiotherapy alone; over a period of 10 weeks, with one or two sessions weekly. OUTCOME ASSESSMENT: All patients had completed the protocols and were assessed using a visual analogue scale for pain intensity (VASpain) and muscle tension (VASmt), the Neck Disability Index: Brazilian Portuguese version for functional disability, and the cranio-cervical Flexion Test for isometric neck muscle strength (INMS); in the periods before treatment (baseline), after 10 weeks of treatment, and after 6 months of follow-up. RESULTS: All groups showed significant improvement (p < 0.001) in these parameters after 10 weeks of treatment and after 6 months of follow-up. Group-1 was superior to Group-3 in pain and functional disability improvements (p<0.05); and Group-1 was superior to both Group-2 (p < 0.01) and Group-3 (p < 0.05) in INMS. After 6 months of follow-up, the improvements of all groups were maintained (p < 0.05). CONCLUSION: The data suggested that acupuncture effect may facilitate and/or enhance physiotherapy performance in musculoskeletal rehabilitation for tension neck syndrome.

Nicaragua has the lowest prevalence of AIDS in Central America. In other countries where AIDS is more prevalent, the first epidemic of asymptomatic infections with human immunodeficiency virus (HIV) and the second of clinical cases of AIDS have been followed by a third epidemic of fear and discrimination. In December 1989 a study was conducted to investigate knowledge and attitudes about AIDS in a sample of 287 adults in Managua. Most of the interviewees had heard of the disease from newspapers and television, and more than 90% understood how HIV was principally transmitted. However, between one-third and one-half the interviewees believed that HIV could be transmitted by causal contact such as kissing (53%) or by mosquito bites (49%). In addition, the majority considered that isolation of HIV-infected persons and control of immigration into the country would be effective measures for preventing the spread of the disease. These results are similar to findings from studies carried out in other countries of Latin America where the HIV and AIDS epidemics started much earlier. This would suggest that the so-called "third epidemic" of discrimination and fear is affecting Nicaragua in advance of the other two.
