O presente estudo pretende sistematizar os resultados dos estudos realizados sobre AF, EF e saude do Idoso mocambicano. Foram recolhidos resultados publicados dos estudos realizados entre 2003 a 2015 pelo Nucleo de Investigacao em Actividade Fisica e Saude (NIAFS). Os principais resultados, por um lado, apontaram para a prevalencia de sobrepeso, obesidade e osteoporose, para alem de elevados NAF e ApF. Contudo, estes resultados, aparentemente, tem sido influenciados pela zona de residencia. Por outro lado, os distintos indicadores da QV estudados tem-se mostrado favoraveis para as idosas praticantes do programa “Envelhecer com Saude” do que as nao praticantes. Na generalidade, deve-se ter bastante cuidado ao interpretar estes resultados, principalmente por estarem restritos ao seu universo da amostra utilizada, o que eleva a importância para a continuidade dos estudos nesta area de investigacao. Palavras-chaves: Actividade Fisica, Exercicio Fisico, Saude, Idosos.

Para tanto, o peso corporal, a estatura, a glicemia, a colesterolemia, a pressão arterial e a prática de AF (ocupacional, deslocamento e lazer) foram avaliados em 223 adultos desta cidade (37,2±6,3 anos, 57% mulheres). As comparações entre gêneros (homens e mulheres) e idades (mediana do grupo-> e ≤ 36,9 anos) foram feitas pelo teste Qui-quadrado. P<0,05 foi aceito como significante. As prevalências dos FRC foram elevadas para excesso de peso (54,6%) e obesidade central (30,4%). Contrariamente, apenas 4,1% dos indivíduos foram considerados insuficientemente ativos ou inativos, sendo que 52,2% relataram praticar alguma AF de deslocamento, 89,3% ocupacional e 34,8% de lazer. Os homens apresentaram maior prevalência de sobrepeso, colesterol alto e prática de alguma AF de lazer. As mulheres apresentaram maior prevalência de obesidade, obesidade central e prática de alguma AF de deslocamento. Os indivíduos com mais de 36,9 anos apresentaram maior prevalência de colesterol elevado e hipertensão, menor prevalência de prática de alguma AF ocupacional e maior prevalência de AF suficiente de lazer. Conclui-se, portanto, que nos adultos residentes da cidade de Muzambinho, a prevalência dos FRC referentes à gordura corporal foi elevada apesar da alta prevalência de AF total suficiente. A prevalência dos FRC e da prática de AF nos diferentes domínios diferiram entre gêneros e idades.

O seu nome já está gravado para sempre como um dos maiores acadêmicos que a área de Educação Física e Ciências do Desporto da lusofonia já conheceu. A sua carreira universitária, por razões regimentais, encerrou-se, mas a sua carreira acadêmica continuará firme e forte inspirando a todos nessa brilhante jornada que está longe de terminar. É necessário e prudente deixar bem claro, de partida, que falar das contribuições de um acadêmico de tamanha reputação e prestígio, efetivadas com enorme dedicação, por tanto tempo e numa diversidade de frentes, é uma tarefa extremamente complexa e, porque não, perigosa. Certamente, uma avaliação justa e coerente das contribuições de Jorge Olímpio Bento só a história será capaz de realizar, de modo que as considerações a seguir merecem ser tomadas e analisadas com a devida parcimônia.

The persistence of this association in moderately-to highly active populations is not, however, well established. The aim of the present study was to investigate this association in a Brazilian city with high frequency of active youths. We assessed 122 subjects (9.9 ± 1.3 years) from Muzambinho city. Body mass index, waist circumference, glycaemia, cholesterolaemia, systolic and diastolic blood pressures were measured. Maximal handgrip strength and one-mile walk/run test were used. Leisure time PA was assessed by interview. Poisson regression was used in the analysis. The model explained 11% of the total variance. Only relative muscular strength and one-mile walk/run were statistically significant (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .05). Those who needed more time to cover the one-mile walk/run test had an increased in metabolic risk of 11%, and those with greater strength reduced the risk by about 82%. In conclusion, children and youths from an active population who need less time to cover the one-mile walk/run test or who had greater muscular strength showed a reduced metabolic risk. These results suggest that even in children and youths with high leisure time PA, a greater aerobic fitness and strength might help to further reduce their MMRF.

Aim: To investigate sibling resemblance in GMC, as well as biological and environmental correlates of GMC among Peruvian children. Materials and methods: The sample comprised 1256 biological siblings (6-15 years old), from three geographical areas of Peru. GMC was assessed using the Korperkoordinationtest f€ ur Kinder (KTK) test battery. Anthropometry, biological maturation and physical fitness (PF) were also measured. Multilevel modelling was performed using Stata 14 software. Results: In general, sister-sister pairs (SS) showed the highest resemblance in GMC (q ¼ 0.24) compared to brother-sister (BS) (q ¼ 0.10) and brother-brother (BB) pairs (q ¼ 0.07). On average, BB pairs had higher GMC than SS pairs and older siblings had higher GMC than younger siblings. Further, those with lower body mass index (BMI) and higher PF had higher GMC. There was also a significant interaction between age and PF with GMC. Siblings from the rainforest region demonstrated higher GMC than those from sea level and high-altitude siblings demonstrated lower GMC than their sealevel peers. Conclusion: These results demonstrate statistically significant sibling resemblance in GMC. Age, BMI, PF and geographical area were significant correlates of GMC.

Since genetic factors account for the observed variation in each of these traits, it is possible that part of their association may be related to common genetic and/ or environmental influences. Thus, this study was designed to estimate the genetic and environmental correlations of BP and PA phenotypes in nuclear families from Muzambinho, Brazil. Families including 236 offspring (6 to 24 years) and their 82 fathers and 122 mothers (24 to 65 years) were evaluated. BP was measured, and total PA (TPA) was assessed by an interview (commuting, occupational, leisure time, and school time PA). Quantitative genetic modeling was used to estimate maximal heritability (h 2), and genetic and environmental correlations. Heritability was significant for all phenotypes (systolic BP: h 2 = 0.37 ± 0.10, P < 0.05; diastolic BP: h 2 = 0.39 ± 0.09, P < 0.05; TPA: h 2 = 0.24 ± 0.09, P < 0.05). Significant genetic (r g) and environmental (r e) correlations were detected between systolic and diastolic BP (r g = 0.67 ± 0.12 and r e = 0.48 ± 0.08, P < 0.05). Genetic correlations between BP and TPA were not significant, while a tendency to an environmental crosstrait correlation was found between diastolic BP and TPA (r e =-0.18 ± 0.09, P = 0.057). In conclusion, BP and PA are under genetic influences. Systolic and diastolic BP share common genes and environmental influences. Diastolic BP and TPA are probably under similar environmental influences.

Diminishing benefits of urban living for children and adolescents' growth and development NCD Ris... more Diminishing benefits of urban living for children and adolescents' growth and development NCD Risk Factor Collaboration (NCD-RisC)* Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being 1-6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5-19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m-2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified.

Currently, there are little to no data describing prevalences and correlates of movement behaviours among children in low-middle-income countries. The few available reports do not include both urban and rural respondents, despite the large proportion of rural populations in low-middle-income countries. We compared the prevalence of meeting 24-h movement guidelines and examined correlates of meeting the guidelines in a sample of urban and rural Mozambican schoolchildren. Methods: This is cross-sectional study of 9-11 year-old children (n = 683) recruited from 10 urban and 7 rural schools in Mozambique. Moderate-to vigorous-intensity physical activity (MVPA) and sleep duration were measured by waist-worn Actigraph GT3X+ accelerometers. Accelerometers were worn 24 h/day for up to 8 days. Recreational screen time was self-reported. Potential correlates of meeting 24-h movement guidelines were directly measured or obtained from validated items of context-adapted questionnaires. Multilevel multivariable logit models were used to determine the correlates of movement behaviours. Meeting 24-h movement guidelines was defined as ≥60 min/ day of MVPA, ≤2 h/day of recreational screen time, and between 9 and 11 h/night of sleep. Results: More rural (17.7%) than urban (3.6%) children met all three 24-h movement guidelines. Mean MVPA was lower (82.9 ± 29.5 min/day) among urban than rural children (96.7 ± 31.8 min/day). Rural children had longer sleep duration (8.9 ± 0.7 h/night) and shorter recreational screen time (2.7 ± 1.9 h/day) than their urban counterparts (8.7 ± 0.9 h/night and 5.0 ± 2.3 h/day respectively). Parental education (OR: 0.37; CI: 0.16-0.87), school location (OR: 0.21; CI: 0.09-0.52), and outdoor time (OR: 0.67; CI: 0.53-0.85) were significant correlates of meeting all three 24-h movement guidelines. Conclusions: Prevalence and correlates of meeting movement guidelines differed between urban and rural schoolchildren in Mozambique. On average, both groups had higher daily MVPA minutes, shorter sleep duration, and higher recreational screen time than the 24-h movement guidelines recommend. These findings (e.g., higher than recommended mean daily MVPA minutes) differ from those from high-income countries and highlight the need to sample from both urban and rural areas.

Methods: Physical activity was assessed by pedometers in a sample of 15- to 64-year-old subjects from Maputo, Mozambique. Participants wore a pedometer for 7 consecutive days, and physical inactivity was classified using a variety of approaches: sedentary (<5000 steps/d), physically inactive (<7500 steps/d), and no moderate-to-vigorous physical activity (MVPA < 1 min/d). Results: The percentage of sedentary subjects was 17.8%, and the percentage who were physically inactive was 41.8%. A total of 9.0% of participants participated in no MVPA (<1 min/d). Logistic regression analysis showed that females had a higher odds of being sedentary or inactive and having no MVPA compared with males. Unemployed participants were more sedentary and inactive than those who were employed. Socioeconomic status and body m...

However, few studies have examined how active transportation (AT) and device-based measures of PA vary within and between countries in sub-Saharan Africa.PurposeThis cross-sectional study sought to investigate the prevalence and correlates of AT and device-measured PA among children living in urban, peri-urban and rural areas in three African countries representing Eastern, Western and Southern regions of Africa.Methods3,205 participants (53.3% girls; 46.7% boys) aged 10–12 years were recruited in Kenya, Nigeria and Mozambique. Data were collected using a child questionnaire, a parent/guardian questionnaire and PiezoRx® pedometers. ANCOVA and binary logistic regression analyses were used to examine the correlates of AT and PA while controlling for gender, age, parent education and vehicle ownership.ResultsParticipants accumulated an average of 45.6±23.5 min/day of moderate-to-vigor...

This study aimed to document secular changes in habitual physical activities of Mozambican youth between 1992, 1999 and 2012. A total of 3393 youth (eight–15 years), were measured in three different time periods (1992, 1999, 2012). Habitual physical activity (PA) was estimated with a questionnaire, including items related to household chores, sport participation, traditional games and walking activities. Biological maturation was assessed. Analysis of Covariance (ANCOVA) was used to compare mean differences in PA across the years. Significant decreases between 1992–1999 and 1992–2012 were observed for boys in household chores, games and
