Concern About Falling, Confidence in Balance, Quality of Life, and Depression Symptoms in Community-Dwelling Older Adults After a 24-week Dual-Task Training With Variable and Fixed Priority: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effect of a 24-week dual-task training with progression from variable to fixed priority on the concern about falling, confidence in balance, quality of life, and depression symptoms in community-dwelling older adults. METHODS: A total of 60 participants (60-80 y.o.) were randomly allocated into a dual-task training group with progression from variable to fixed priority (experimental group) or into a dual-task training group with variable priority (control group). RESULTS: No between-group difference was observed after the intervention. A significant time effect showed a reduction in concern about falling [mean difference (MD) = -2.91)] and depression symptoms (MD = -1.66), an increase in the physical function (MD = 7.86), overall mental health (MD = 5.82), perception of vitality, energy, and less fatigue (MD = 10.45), general perception of overall health (MD = 6.81), and their health compared to the last year (MD = 11.89). CONCLUSION: The experimental protocol was not superior to the control one. However, both protocols improved these outcomes.

Prevalence of headache in adolescents and association with use of computer and videogames.

The aim of this study was to determine the prevalence of headache in adolescents and its association with excessive use of electronic devices and games. The sample comprised 954 adolescents of both sexes (14 to 19 years) who answered a questionnaire about use of computers and electronic games, presence of headache and physical activity. The binary and multinomial logistic regression, with significance level of 5% was used for inferential analysis. The prevalence of headache was 80.6%. The excessive use of electronics devices proved to be a risk factor (OR = 1.21) for headache. Subjects aged between 14 and 16 years were less likely to report headache (OR = 0.64). Regarding classification, 17.9% of adolescents had tension-type headache, 19.3% had migraine and 43.4% other types of headache. The adolescents aged form 14 to 16 years had lower chance (OR ≤ 0.68) to report the tension-type headache and other types of headache. The excessive use of digital equipment, electronic games and attending the third year of high school proved to be risk factors for migraine-type development (OR ≥ 1.84). There was a high prevalence of headache in adolescents and high-time use of electronic devices. We observed an association between excessive use of electronic devices and the presence of headache, and this habit is considered a risk factor, especially for the development of migraine-type.

Primary headaches among adolescents and their association with excessive computer use / Cefaleias primárias em adolescentes e sua associação com o uso excessivo de computador

ABSTRACT BACKGROUND AND OBJECTIVES: The use of electronic devices as entertainment and recreation means has directly affected adolescents’ lives; however their excessive use may bring consequences. This study aimed at observing the prevalence of primary headaches and their possible association with excessive use of computers among adolescents. METHODS: Participated in the study 262 teenagers aged between 14 and 19 years, students of a public school, who have answered a questionnaire to evaluate socio-demographic variables, data on computer use, presence of headache symptoms and level of physical activity. Multiple models of binary and multinomial logistic regression were used to evaluate the association among variables. Significance level was 5%. RESULTS: Prevalence of headache was 87.8%. There has been no significant difference in the prevalence of headache between genders, but among classification types, tension headache was more prevalent among females (35.4%). Females aged between 12 and 15 years and excessive computer use had higher chances of reporting headache. Females have 15.61 times more chance of reporting tension headache. Adolescents reporting excessive computer use had 2.54 times more chance of reporting migraine. CONCLUSION: Results have shown high prevalence of primary headache among adolescents, being migraine the most prevalent type. Abusive computer use were considered risk factors for the development of headache.

RESUMO JUSTIFICATIVA E OBJETIVOS: A inclusão de dispositivos eletrônicos como meios de entretenimento e recreação trouxe repercussão direta na vida dos adolescentes, todavia o uso excessivo pode gerar consequências. Objetivou-se verificar a prevalência de cefaleias primárias e sua possível associação com o uso excessivo de computador em adolescentes. MÉTODOS: Participaram do estudo 262 adolescentes com idade entre 14 e 19 anos, estudantes de uma escola pública, que responderam um questionário que visou avaliar variáveis sócio-demográficas, dados sobre uso de computador, presença de sintomas de cefaleia e nível de atividade física. Foram utilizados modelos múltiplos de regressão logística binária e multinomial para avaliar a associação entre as variáveis. O nível de significância adotado foi de 5%. RESULTADOS: A prevalência de cefaleia foi de 87,8%. Não houve diferença significativa quanto à presença de cefaleia entre gêneros, mas dentre os tipos de classificação, a tensional apresentou maior frequência entre o gênero feminino (35,4%). Indivíduos do gênero feminino, faixa etária entre 12 e 15 anos e uso excessivo de computador apresentaram maiores chances de relatar cefaleia. O gênero feminino apresenta 15,61 vezes mais chances de relatar cefaleia do tipo tensional. Adolescentes que referiram uso excessivo do computador apresentaram 2,54 vezes mais chances de relatar migrânea. CONCLUSÃO: Os resultados mostram alta prevalência de cefaleia primária entre os adolescentes, sendo a migrânea a mais prevalente. O uso abusivo do computador foi considerado fatores de risco para o desenvolvimento de cefaleia.

Prevalence of musculoskeletal pain in adolescents and its association with the use of electronic devices / Prevalência de dor musculoesquelética em adolescentes e sua associação com o uso de dispositivos eletrônicos

ABSTRACT BACKGROUND AND OBJECTIVES: The use of electronic devices has reconfigured the daily life of adolescents; however, their excessive use may be associated to health problems. This study aimed at observing the prevalence of musculoskeletal pain among adolescents and its association with the use of computers and videogames. METHODS: Sample was made up of 265 adolescents of both genders (14 to 19 years old), students of a public school, who have answered a questionnaire about the use of electronic devices, musculoskeletal pain, physical activity and demographics. Values of absolute and relative frequency, confidence intervals and mean and standard deviation were expressed for descriptive analysis. Independent t and Chi-square tests were used for comparison between genders, and multiple logistic regression model was used for association test. All tests had significance level of 5%. RESULTS: The prevalence of musculoskeletal pain was 72.1%, being significantly higher for females. There has been no association between musculoskeletal pain and the use of electronic devices; however it was identified that females had 10.66 times more probability of reporting this type of pain. Cervical and thoraco-lumbar pains were associated to females (OR=1.80), and individuals attending the 2nd and 3rd year were associated to cervical pain (OR≥2.26). CONCLUSION: There has been high prevalence of musculoskeletal pain among adolescents, especially females. Although not observing association between pain and use of electronic devices, it was noted that those attending the last years of high school and of the female gender had higher risk to develop musculoskeletal pain. .

RESUMO JUSTIFICATIVA E OBJETIVOS: O uso de dispositivos eletrônicos reconfigurou o cotidiano dos adolescentes, porém a utilização excessiva pode estar associada a problemas de saúde. O objetivo deste estudo foi verificar a prevalência de dor musculoesquelética em adolescentes e sua associação com o uso de computador e jogos eletrônicos. MÉTODOS: A amostra foi composta por 265 adolescentes de ambos os gêneros (14 a 19 anos), estudantes de uma escola pública, que responderam um questionário sobre uso de dispositivos eletrônicos, dor musculoesquelética, atividade física e dados sócio-demográficos. Para análise descritiva, foram expressos valores de frequência absoluta, relativa, intervalos de confiança e média e desvio padrão. Foram utilizados o teste t independente e Qui-quadrado para comparação entre gêneros, e modelo de regressão logística múltipla para teste de associação. Todos os testes tiveram nível de significância de 5%. RESULTADOS: A prevalência de dor musculoesquelética foi de 72,1%, sendo significativamente maior no gênero feminino. Não foi encontrada associação entre dor musculoesquelética e uso de dispositivos eletrônicos. Porém, foi identificado que o gênero feminino apresenta 10,66 mais probabilidades de referir esse tipo de dor. As dores cervicais e toracolombares tiveram associação com gênero feminino (OR=1,80) e os indivíduos que cursam o 2º e 3º ano tiveram associação com dor cervical (OR≥2,26). CONCLUSÃO: Evidenciou-se alta prevalência de dor musculoesquelética nos adolescentes, principalmente do gênero feminino. Embora não se tenha observado associação entre dor e uso de dispositivos eletrônicos, notou-se que aqueles que cursam os últimos anos do ensino médio e do gênero feminino apresentam maior risco de desenvolver dores musculoesqueléticas. .

Este estudo objetivou verificar a prevalência de cefaleia em adolescentes e sua associação com o uso excessivo de computador e jogos eletrônicos. A amostra foi composta por 954 adolescentes (14 a 19 anos), de ambos os sexos, que responderam ao questionário sobre uso de computadores e jogos eletrônicos, presença de cefaleia e atividade física. Foi utilizada a regressão logística binária e multinomial, com nível de significância de 5%. Evidenciou-se alta prevalência de cefaleia (80,6%) e elevado tempo de uso de dispositivos eletrônicos. O uso excessivo dos dispositivos eletrônicos mostrou-se fator de risco para cefaleia. Os sujeitos com idade entre 14 e 16 anos apresentaram menor chance de relatar a cefaleia. Em relação ao tipo, 17,9% apresentaram cefaleia do tipo tensional, 19,3% migrânea e 43,4% outros tipos de cefaleia. Os adolescentes com idade entre 14 e 16 anos apresentam menor chance de relatar a cefaleia do tipo tensional e de outros. Estar cursando o terceiro ano e usar excessivamente equipamentos digitais mostraram-se fatores de risco para cefaleia migrânea. Os resultados permitem concluir que o uso excessivo de dispositivos eletrônicos está associado à presença de cefaleia, principalmente do tipo migrânea.
