“…Differences in total PA and SB between sexes are present in many studies, mostly with girls being less active than boys. 12,13,32 An explanation might be the earlier onset of puberty and sexual maturation in girls 38 ; however, sex differences were already present at the 6-year-old mark in our study (well before puberty). This information can be useful when planning activity programs, tailoring suggested activities' intensity and duration.…”

Physical activity (PA) is presumed to decline during childhood and adolescence, but only few long-term studies about PA development during this period of life exist. We assessed PA and sedentary behavior (SB) over a 5-year period to gain a better understanding of the extent of change in activity and potential influencing factors. METHODS: PA and SB of 600 children from the Childhood Obesity Project were objectively measured with the SenseWear Armband 2 at the ages of 6, 8, and 11 years, resulting in 1254 observations. Longitudinal changes of total PA, moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and SB were modeled with mixed-effects models. RESULTS: Total PA revealed a significant quadratic decline with age (P < .001), resulting in a change of total PA by −75.3 minutes per day from 6 to 11 years. LPA linearly declined (P < .001) by 44.6 minutes per day, MVPA quadratically declined (P < .001) by an overall 30.7 minutes, whereas SB increased significantly (+107 minutes; P = .001). Boys showed a steeper decline in LPA (P = .003) and MVPA (P < .001) than did girls. Higher fat mass index and BMI z scores were associated with lower levels of total PA and MVPA and higher levels of SB (all P < .001). CONCLUSIONS: We showed that PA decreased, and SB increased in earlier years than previously thought. MVPA remained relatively stable until 8 years, but revealed a drop-off at 11 years, identifying this period as a crucial time for intervention.

“…The underlying mechanisms that can explain the differences between sexes are not clear 29 , 30 . However, biological maturation, levels of physical activity, excessive use to electronic equipment, eating habits and substance consumption may explain the differences 31 , 32 . Therefore, this study aimed to verify if girls are at a higher risk to present sleep problems both in quantity and quality of sleep, and if associations of a good or a poor sleep perception are different between boys and girls either considering the comparison of same age boys and girls either introducing an age gap to balance delayed puberty in boys (2 years).…”

ObjectiveSleep is of upmost importance for everybody and especially for adolescents who face life and leisure challenges that may impair their sleep. This study aimed to verify if girls are at a higher risk to present sleep problems and if associations of a sleep perception are different between sexes even when accounting for biological maturation. MethodsData is from the HBSC Portuguese survey 2014, all variables were self-reported. Participants were 3869 adolescents (2057 girls), mean age 14.8 years. Participants' socio-demographic characteristics included sex, age, school grade, father and mother education; besides participants were inquired about sleep duration and characteristics of their sleep quality. ResultsSleep deprivation was reported by 13.1% of the adolescents (girls 14.3%, boys 11.7%, p<0.05). The most prevalent characteristics of poor sleep quality were waking up tired (50.8%) and difficulties falling asleep (19.5%), for both girls presented higher prevalence than boys. Overall, girls presented a poorer sleep health with low quality and quantity of sleep. Furthermore, associations of an enough and good sleep were different between boys and girls, even when controlling for the impact of delayed pubertal maturity. DiscussionTogether with screen time, substance use, poorer nutrition, sedentary behaviours and abuse of screen time, sleep is an issue that must be addressed by professionals, families and public policies with impact in family life and family routines. Modelling a health education in schools should include the sleep topic. In addition, yes, sex matters and must be included on board.

“…Com relação à faixa etária, os trabalhos contemplaram os três períodos da adolescência: inicial (dos 10 aos 13 anos), intermediária (dos 14 aos 16 anos) e final (dos 17 aos 20 anos incompletos) 29 . Dentre todos os trabalhos finais selecionados, 91,7% (n = 11) encontravam-se na fase inicial da adolescência 20,30,24,[31][32][33][34][35][36][37][38] . Nenhum estudo avaliou o período correspondente à adolescência como um todo, de acordo com a OMS 39 .…”

“…Em cinco artigos foi identificada relação inversa entre maturação sexual e nível de atividade física 20,30,31,34,35 . No entanto, dois estudos especificamente demonstraram associação direta, e evidenciaram que meninas e meninos mais maduros ou em estados maturacionais sexuais mais avançados tendem a ser mais ativos fisicamente [24][25][26][27][28][29][30][31][32][33] . Três trabalhos apontaram que as mudanças na prática de atividade física são mais influenciadas pelo sexo do que pela maturação 19,32,37 .…”

“…Alguns instrumentos foram utilizados para a avaliação do estado maturacional nos artigos pesquisados e dentre eles estão os estágios de Tanner (autoavaliação) 35 ; the criterion of predicted percentage of maturity (adultstature), usado para predizer a estatura adulta a partir da idade atual, constituindo o método de Khamis-Roche 19,40 ; the pubertal development scale 20,24,32,36 . Também foram utilizadas perguntas para determinar a idade da menarca (status quo method) 30 e a somatic maturity status 31 .…”

Resumo O objetivo é verificar a associação entre maturação sexual e atividade física na adolescência. Trata-se de um estudo de revisão sistemática elaborado a partir de artigos publicados entre 2008 a 2018 nas bases de dados Medline-PubMed, SciELO, Web of Science, Scopus, Lilacs e Adolec BVS. Utilizou-se os descritores e palavras-chave adolescente, maturação sexual, inquérito, questionário e atividade física, no idioma português e sua equivalência na língua inglesa e foram identificados 806 artigos. Após aplicação dos critérios de seleção foram incluídos 12 artigos. Maior nível da prática de atividade física foi observado em adolescentes em fase de maturação sexual inicial. A evolução do desenvolvimento maturacional sexual parece estar correlacionado à redução dos níveis de atividade física. Os achados não evidenciam um consenso sobre associação entre maturação sexual e nível de atividade física quanto à predisposição direta ou inversa da maturação sexual em relação ao nível de atividade física entre adolescentes. São necessárias mais pesquisas para compreender essa relação e possibilitar aos profissionais envolvidos com a saúde do adolescente agir efetivamente no combate à inatividade física.
