Abstract

OBJECTIVE

The objective of this study is to establish cutoff points for the number of steps/day and minutes/day of moderate to vigorous physical activity in relation to the risk of childhood overweight and obesity and their respective associations. In addition, we aim to identify the amount of steps/day needed to achieve the recommendation of moderate to vigorous physical activity in children from São Caetano do Sul.

METHODS

In total, 494 children have used an accelerometer to monitor steps/day and the intensity of physical activity (min/day). The moderate to vigorous physical activity has been categorized according to the public health recommendation (≤ 60 versus > 60 min/day). Overweight or obesity is defined as body mass index > +1 SD, based on reference data from the World Health Organization. The data on family income, education of parents, screen time, diet pattern, and sedentary time have been collected by questionnaires. Logistic regression and Receiver Operating Characteristic curves have been constructed.

RESULTS

On average, boys walked more steps/day (1,850) and performed more min/day of moderate to vigorous physical activity (23.1) than girls. Overall, 51.4% of the children have been classified as eutrophic and 48.6% as overweight or obese. Eutrophic boys walked 1,525 steps/day and performed 18.6 minutes/day more of moderate to vigorous physical activity than those with overweight/obesity (p < 0.05). The same has not been found in girls (p > 0.05). The cutoff points to prevent overweight and obesity in boys and girls were 10,500 and 8,500 steps/day and 66 and 46 min/day of moderate to vigorous physical activity, respectively. The walking of 9,700 steps/day for boys and 9,400 steps/day for girls ensures the scope of the recommendation of moderate to vigorous physical activity.

CONCLUSIONS

In boys, steps/day and moderate to vigorous physical activity have been negatively associated with body mass index, regardless of race, family income, education of parents, screen time, diet pattern, and sedentary time. We suggest, for steps/day and moderate to vigorous physical activity, studies with different ages and populations, with different designs, so as to inform the cause and effect relationship with various health parameters.

OBJETIVO

Estabelecer pontos de corte para o número de passos/dia e min/dia de atividade física com intensidade moderada a vigorosa em relação ao risco do excesso de peso e obesidade infantil e suas respectivas associações. Além de identificar a quantidade de passos/dia necessários para atingir a recomendação de atividade física de moderada a vigorosa em crianças de São Caetano do Sul.

MÉTODOS: No total, 494 crianças usaram acelerômetro para monitorar os passos/dia e a intensidade da atividade física (min/dia). A atividade física de moderada a vigorosa foi categorizada de acordo com a recomendação de saúde pública (≤ 60 versus > 60 min/dia). Excesso de peso ou obesidade foi definido como índice de massa corporal > +1 DP, com base nos dados de referência da Organização Mundial de Saúde. Renda familiar, escolaridade dos pais, tempo de tela, padrão de dieta, e tempo sedentário foram coletados por questionários. Foram construídas curvas Receiver Operating Characteristic e regressão logística.

RESULTADOS

Em média, os meninos realizaram mais passos/dia (1.850) e min/dia de atividade física de moderada a vigorosa (23,1) do que as meninas. No geral, 51,4% das crianças foram classificadas como eutróficas e 48,6% com excesso de peso ou obesidade. Meninos eutróficos realizavam 1.525 passos/dia e 18,6 min/dia de atividade física de moderada a vigorosa a mais do que aqueles com excesso de peso/obesidade (p < 0,05). O mesmo não foi encontrado nas meninas (p > 0,05). Os pontos de corte para evitar excesso de peso e obesidade nos meninos e meninas foram 10.500 e 8.500 passos/dia e 66 e 46 min/dia de atividade física de moderada a vigorosa, respectivamente. A realização de 9.700 passos/dia (meninos) e 9.400 passos/dia (meninas) garante o alcance da recomendação de atividade física de moderada a vigorosa.

CONCLUSÕES: Nos meninos, passos/dia e atividade física de moderada a vigorosa foram negativamente associados com o índice de massa corporal, independentemente da raça, renda familiar, escolaridade dos pais, tempo de tela, padrão de dieta e tempo sedentário. Sugere-se para passos/dia e atividade física de moderada a vigorosa, estudos em diversas idades e populações, com diferentes delineamentos, para assim informar a relação causa e efeito com diversos parâmetros de saúde.

摘要

目的

本研究的目的是确定与儿童超重和肥胖风险及其各自关联相关的每日步数和中度至剧烈身体活动的每日分钟数的切点。此外,我们旨在确定南圣卡埃塔诺儿童达到中度至剧烈身体活动建议所需的每日步数。

方法

共有494名儿童使用加速度计监测每日步数和身体活动强度(分钟/天)。中度至剧烈身体活动已根据公共卫生建议进行分类(≤60与>60分钟/天)。超重或肥胖定义为基于世界卫生组织参考数据的体重指数>+1标准差。通过问卷收集家庭收入、父母教育程度、屏幕时间、饮食模式和久坐时间的数据。构建了逻辑回归和受试者工作特征曲线。

结果

平均而言,男孩每天走的步数(1850步)和进行中度至剧烈身体活动的分钟数(23.1分钟)比女孩多。总体而言,51.4%的儿童被归类为营养良好,48.6%为超重或肥胖。营养良好的男孩每天走1525步,进行中度至剧烈身体活动的时间比超重/肥胖男孩多18.6分钟/天(p<0.05)。在女孩中未发现相同情况(p>0.05)。预防男孩和女孩超重和肥胖的切点分别为每日10500步和8500步,以及中度至剧烈身体活动每日66分钟和46分钟。男孩每天走9700步和女孩每天走9400步可确保达到中度至剧烈身体活动的建议范围。

结论

在男孩中,无论种族、家庭收入、父母教育程度、屏幕时间、饮食模式和久坐时间如何,每日步数和中度至剧烈身体活动与体重指数呈负相关。对于每日步数和中度至剧烈身体活动,建议开展针对不同年龄和人群、采用不同设计的研究,以了解与各种健康参数的因果关系。
