Observations of activities of contemporary subsistence agricultural communities may provide insights into the lifestyle of youth of 2 to 3 generations ago. The purpose of this study was to document age- and sex-associated variation in household activities and daily steps walking to school of youth 9-17 years in an indigenous subsistence agricultural community in Oaxaca, southern Mexico. Activities during leisure were also considered. A cross-sectional survey of a rural Zapotec-speaking community was undertaken, and respondents included 118 boys and 152 girls, aged 8.7-17.9 years. Household and leisure activities were documented by questionnaire and subsequent interview. Household activities were classified by estimated intensity for before and after school and on the weekend, and an estimate of METS per day accumulated while doing chores was derived. Number of steps from home to school was estimated. Contingency table analysis and MANCOVA controlling for age was used to evaluate results. Household activities tended to cluster at light and moderate intensities in girls and at moderate to moderate-to-vigorous intensities in boys. Estimated METS per day in approximately 2 h of chores differed significantly by sex. Secondary school girls expended significantly more METS per day in chores than primary school girls, but there was no difference by school level in boys. The daily round trip from home to school was approximately 2400 steps for primary students and approximately 2700 and approximately 3100 steps for secondary boys and girls, respectively. Television viewing and participation in sports were major leisure activities for boys and girls. Daily household chores, walking, and leisure activities suggest moderately active and moderately-to-vigorously active lifestyles in girls and boys, respectively, in this indigenous subsistence agricultural community.
对当代自给农业社区活动的观察,可能有助于深入了解两三代以前年轻人的生活方式。本研究旨在记录墨西哥南部瓦哈卡州一个土著自给农业社区中9至17岁青少年在家庭活动以及步行上学的日常步数方面与年龄和性别相关的差异。同时也考虑了休闲活动。对一个讲萨波特克语的农村社区进行了横断面调查,受访者包括118名男孩和152名女孩,年龄在8.7至17.9岁之间。通过问卷调查及后续访谈记录家庭和休闲活动。家庭活动按上学前、放学后以及周末的估计强度进行分类,并得出做家务时每天累计的代谢当量估计值。估算从家到学校的步数。使用列联表分析和控制年龄的多变量协方差分析来评估结果。女孩的家庭活动往往集中在轻度和中度强度,而男孩则集中在中度到中高强度。约2小时家务的每日代谢当量估计值在性别上有显著差异。中学女生每天做家务消耗的代谢当量明显多于小学女生,但男生在不同学校水平之间没有差异。小学生每天从家到学校的往返步数约为2400步,中学男生和女生分别约为2700步和3100步。看电视和参加体育活动是男孩和女孩的主要休闲活动。在这个土著自给农业社区,日常家务、步行和休闲活动表明女孩和男孩分别拥有适度活跃和中度到高度活跃的生活方式。
