The Joint Associations of Physical Activity and Sedentary Behaviors on Adiposity during Adolescence: The 1993 Pelotas (Brazil) Cohort Study. CHILDREN (BASEL, SWITZERLAND) 2023; 10:265. [PMID: 36832397 PMCID: PMC9954888 DOI: 10.3390/children10020265] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 01/17/2023] [Accepted: 01/28/2023] [Indexed: 02/04/2023]
Abstract
A prior study conducted in high-income countries demonstrated that specific sedentary behavior, such as TV viewing, is prospectively associated with adiposity in both active and inactive adolescents. The aim of this study was to examine the joint associations of sedentary behaviors and moderate- and vigorous-intensity physical activity (MVPA) with adiposity among Brazilian adolescents. This prospective cohort study included 377 participants of the 1993 Pelotas (Brazil) Study who completed an accelerometry assessment at age 13 years and a dual-energy X-ray absorptiometry (DXA) assessment at age 18 years. Accelerometer-measured MVPA was dichotomized into high (≥60 min/day) and low (<60 min/day). Accelerometer-measured sedentary time (SED) was dichotomized into low (<49 min/h) and high (≥49 min/h) based on the median. Self-reported TV viewing time was also dichotomized into low (<3 h/day) and high (≥3 h/day) based on the median. We combined the two MVPA groups (high and low) and two SED groups (low and high) to form the four MVPA&SED groups: high&low, high&high, low&low, and low&high. We also created four MVPA&TV groups in the same manner. Fat mass index (FMI; kg/m2) was calculated using DXA-derived fat mass. Multivariable linear regression analyses compared FMI at 18 years among the four MVPA&SED groups and among the four MVPA&TV groups, adjusting for socioeconomic status, energy intake, and baseline adiposity. The analysis results showed that SED or TV viewing time was not prospectively associated with adiposity in both active and inactive Brazilian adolescents. This study suggests that the association between specific sedentary behaviors, such as TV viewing, and adiposity may differ across societal settings-in this case, high-income vs. middle-income countries.

Níveis insuficientes de atividade física de adolescentes associados a fatores sociodemográficos, ambientais e escolares. CIENCIA & SAUDE COLETIVA 2018; 23:4277-4288.

Abstract
Resumo Este estudo investigou as associações entre o nível de atividade física com os fatores sociodemográficos, ambientais e escolares de adolescentes. Participaram 2.545 jovens de 14 a 18 anos dos municípios da Grande Florianópolis. Foi utilizada a versão curta do Questionário Internacional de Atividade Física (IPAQ). A prevalência de jovens inativos foi de 48,6%, sendo maior no sexo feminino (53,9%). Para as moças, a inatividade física esteve associada com a falta de lugares apropriados e gratuitos para a prática de atividade física (OR = 1,30 IC95%1,05-1,82), independente da influência das outras variáveis. Já para os rapazes, aqueles que não possuíam atividade profissional (OR = 1,54 IC95%1,14-2,08), mães de menor instrução (OR = 0,41 IC95% 0,27-0,75) ou mães com ensino superior (OR = 0,35 IC95% 0,17- 0,73), pertencentes a cidades de grande porte (OR = 1,64 IC95%1,17-2,31) e classificação socioeconômica baixa quando comparada à média (OR = 0,69 IC95% 0,49-0,97), apresentaram maior chance de inatividade física. Observou-se que as variáveis sociodemográficas estiveram associadas ao comportamento inativo dos rapazes e às variáveis ambientais se associaram a inatividade física das moças. Já dentre os fatores escolares, apenas a reprovação escolar foi associada com inatividade, e somente para as moças.

Abstract
BACKGROUND Data on objectively measured physical activity are lacking in low- and middle-income countries. The aim of this study was to describe objectively measured overall physical activity and time spent in moderate-to-vigorous physical activity (MVPA) in individuals from the Pelotas (Brazil) birth cohorts, according to weight status, socioeconomic status (SES) and sex. METHODS All children born in 1982, 1993 and 2004 in hospitals in the city of Pelotas, Brazil, constitute the sampling frame; of these 99% agreed to participate. The most recent follow-ups were conducted between 2010 and 2013. In total, 8974 individuals provided valid data derived from raw triaxial wrist accelerometry. The average acceleration is presented in milli-g (1 mg = 0.001g), and time (min/d) spent in MVPA (>100 mg) is presented in 5- and 10-min bouts. RESULTS Mean acceleration in the 1982 (mean age 30.2 years), 1993 (mean age 18.4 years) and 2004 (mean age 6.7 years) cohorts was 35 mg, 39 mg and 60 mg, respectively. Time spent in MVPA was 26 [95% confidence interval (CI) 25; 27], 43 (95% CI 42; 44) and 45 (95% CI 43; 46) min/d in the three cohorts, respectively, using 10-min bouts. Mean MVPA was on average 42% higher when using 5-min bouts. Males were more active than females and physical activity was inversely associated with age of the cohort and SES. Normal-weight individuals were more active than underweight, overweight and obese participants. CONCLUSIONS Overall physical activity and time spent in MVPA differed by cohort (age), sex, weight status and SES. Higher levels of activity in low SES groups may be explained by incidental physical activity.
