The purpose of this study is to assess the relationships between trips in nature, gathering of wild plants, fishing and hunting and weight status.
Data from a cross-sectional questionnaire survey of 996 parents of sixth- and seventh-graders from 38 randomly chosen schools in two Norwegian counties. All data are self-reported: Weight and height (participants were considered as overweight if BMI were 25 or higher), family trips in nature (dichotomized into ≥once a week vs. less than once a week), gathering of wild plants/mushrooms, fishing and hunting (all dichotomized into ≥sometimes vs. never), sex, family education level and general physical activity level. Multivariate logistic regression analyses were performed with overweight as the dependent variable
Adjusting for all outdoor activities; those engaging in nature trips (OR = 0.52; 95% CI = 0.37-0.75) and those engaging in gathering (OR = 0.73; 95% CI = 0.55-0.98) were less frequently overweight, while those fishing (OR = 1.83; 95% CI = 1.35-2.47) were more frequently overweight. After also adjusting for sex, family education level and general physical activity level, nature trips (OR = 0.52; 95% CI = 0.36-0.75) and fishing (OR = 1.53; 95% CI = 1.12-2.10) were still significant, gathering was not. No association between hunting and weight status was observed.
Frequent family trips in nature might be an important behaviour in order to reverse the obesity epidemic.
本研究旨在评估户外活动、采集野生植物、钓鱼和狩猎与体重状况之间的关系。
本研究数据来自挪威两个郡 38 所随机选择的学校 6-7 年级学生的家长参与的横断面问卷调查。所有数据均为自我报告：体重和身高（BMI 等于或高于 25 者被认为超重）、家庭户外活动（分为每周≥一次与每周<一次）、采集野生植物/蘑菇、钓鱼和狩猎（均分为有时与从不）、性别、家庭受教育程度和一般身体活动水平。采用多变量逻辑回归分析，将超重作为因变量。
调整所有户外活动后，参与自然旅行（OR=0.52；95%CI=0.37-0.75）和采集（OR=0.73；95%CI=0.55-0.98）的人超重的可能性较小，而钓鱼（OR=1.83；95%CI=1.35-2.47）的人超重的可能性较大。在进一步调整性别、家庭受教育程度和一般身体活动水平后，自然旅行（OR=0.52；95%CI=0.36-0.75）和钓鱼（OR=1.53；95%CI=1.12-2.10）仍然具有统计学意义，而采集没有统计学意义。狩猎与体重状况之间没有关联。
频繁的家庭自然旅行可能是扭转肥胖流行的重要行为。
