Few studies have examined variations in overweight and obesity by geographic location in youth. The purpose of this study was to investigate the association between urban/rural geographic status and being overweight or obese among Canadian adolescents.
The study involved an analysis of a representative sample of 4851 Canadian adolescents in grades 6 to 10 from the 2001-02 Health Behaviour in School-aged Children Survey. Self-reports of participants' demographics, physical activity, screen time, diet, and body mass index (BMI) were assessed. Adiposity status was determined using the international BMI thresholds for children and youth. Urban/rural status was coded on a five-point scale based on the geographic location of the participants' schools. Logistic regression with generalized estimating equations to adjust for clustering was used to examine the association between urban/rural status and overweight/obesity.
The population was 53.3% female with a mean age of 13.9 years (standard deviation, SD=1.5). Approximately 22.2% were living in rural areas while 14.4% were living in large metropolitan (metro) areas. After adjusting for age, sex, socioeconomic status, and Region of Canada, there was a trend for increasing overweight (p=0.001) and obesity (p=0.03) among adolescents as the level of "rurality" increased (relative odds for most urban to most rural regions for overweight or obese: 1.00, 0.98, 1.18, 1.57, 1.36; obesity: 1.00, 1.06, 1.39, 1.58, 1.56). Conclusion. This study provides new information about patterns of overweight/obesity among Canadian adolescents by urban-rural geographic status. These findings suggest that obesity prevention interventions should be particularly aggressive in rural areas.
很少有研究考察青少年中超重和肥胖情况在地理位置上的差异。本研究的目的是调查加拿大青少年的城乡地理状况与超重或肥胖之间的关联。
该研究对2001 - 02年学龄儿童健康行为调查中4851名6至10年级的加拿大青少年代表性样本进行了分析。评估了参与者的人口统计学、身体活动、屏幕时间、饮食和体重指数(BMI)的自我报告。使用儿童和青少年的国际BMI阈值确定肥胖状况。根据参与者学校的地理位置,城乡状况按五点量表进行编码。使用带有广义估计方程以调整聚类的逻辑回归来检验城乡状况与超重/肥胖之间的关联。
该人群中女性占53.3%,平均年龄为13.9岁(标准差,SD = 1.5)。约22.2%生活在农村地区,而14.4%生活在大城市地区。在调整年龄、性别、社会经济地位和加拿大地区后,随着“农村程度”的增加,青少年中超重(p = 0.001)和肥胖(p = 0.03)呈上升趋势(超重或肥胖的最城市地区与最农村地区的相对比值:1.00、0.98、1.18、1.57、1.36;肥胖:1.00、1.06、1.39、1.58、1.56)。结论。本研究提供了关于加拿大青少年按城乡地理状况划分的超重/肥胖模式的新信息。这些发现表明,肥胖预防干预措施在农村地区应特别积极。
