Keywords: | Motor activity; Lifestyle; Body composition; Public health; Pediatrics; Students; Atividade motora; Estilo de vida; Composição corporal; Saúde pública; Pediatria; Estudantes | Issue Date: | 2020 | Publisher: | Sociedade De Pediatria De Sao Paulo | Project: | The ISCOLE Brazil research project was funded by the Pennington Biomedical Research Center in partnership with Coca-Cola Company | Serial title, monograph or event: | Revista Paulista de Pediatria | Volume: | 39 | Abstract: | Objective: To verify the association of lifestyle, anthropometric,
sociodemographic, family and school environment indicators
with the number of steps/day in children.
Methods: The sample consisted of 334 children (171 boys)
from nine to 11 years old. Participants used the Actigraph
GT3X accelerometer to monitor the number of steps/day,
moderate to vigorous physical activity (MVPA) and sedentary
time (ST) for seven consecutive days. Height, body weight,
body mass index (BMI), waist circumference (WC), and body
fat were also measured. Lifestyle indicators such as diet,
environment, neighborhood, and parental schooling level
were obtained with questionnaires. For the identification
of variables associated to the number of steps/day, multiple
linear regression models were used.
Results: The mean steps/day of boys and girls were statistically
different (10,471 versus 8,573; p<001). Among boys, the variables
associated to the number of steps/day were: MVPA (β=0.777),
ST (β=-0.131), BMI (β=-0.135), WC (β=-0.117), and BF (β=-0.127).
Among girls, the variables associated to the number of steps/day
were: MVPA (β=0.837), ST (β=-0.112), and parents’ educational
level (β=0.129).
Conclusions: Lifestyle indicators, body composition variables
and parental educational level influence the number of
steps/day of children, and MVPA and ST are common for
both sexes. Objetivo: Verificar a associação dos indicadores de estilo de vida, antropométricos, sociodemográficos, ambiente familiar e escolar com a quantidade de passos/dia em crianças. Métodos: A amostra constituiu-se de 334 crianças (171 meninos) de 9 a 11 anos. Os participantes utilizaram o acelerômetro Actigraph GT3X para monitorar a quantidade de passos/dia, a atividade física moderada a vigorosa (AFMV) e o tempo sedentário (TS) durante sete dias consecutivos. Estatura, massa corporal, índice de massa corpórea (IMC), circunferência de cintura (CC) e gordura corporal também foram mensurados. Indicadores de estilo de vida, como dieta, ambiente, vizinhança e nível de escolaridade dos pais, foram obtidos por questionários. Para identificar as variáveis associadas à quantidade de passos/dia, utilizaram-se modelos de regressão linear múltipla. Resultados: As médias de passos/dia dos meninos e das meninas foram estatisticamente diferentes (10.471 versus 8.573; p<0,001). Nos meninos, as variáveis associadas à quantidade de passos/dia foram: AFMV (β=0,777), TS (β=-0,131), IMC (β=-0,135), CC (β=- 0,117) e gordura corporal (β=-0,127). Já entre as meninas, as variáveis associadas à quantidade de passos/dia foram: AFMV (β=0,837), TS (β=-0,112) e nível educacional dos pais (β=0,129). Conclusões: Indicadores de estilo de vida, variáveis de composição corporal e nível educacional dos pais influenciaram a quantidade de passos/dia das crianças. A AFMV e o TS foram comuns para ambos os sexos. |
