To examine the patterns of weight loss behaviour and the association between weight loss attempts with actual weight status and children's and parental perceptions of weight status.
A cross-sectional study.
Karnataka, South India.
1874 girls and boys aged 8-14 years from seven schools in Karnataka, South India.
The association between weight loss attempts and sociodemographic factors, weight status and the child's or the parent's perception of weight status.
Approximately 73% of overweight and obese, 35% of normal weight and 22% of underweight children attempted to lose weight. Children of lower socioeconomic groups studying in schools in the local vernacular and overweight/obese children were more likely to attempt to lose weight (adjusted OR ie, AOR=1.57, 95% CI 1.11 to 2.25; AOR=4.38, 95% CI 2.64 to 7.28, respectively). Perception of weight status was associated with weight loss attempts. Thus, children who were of normal weight but perceived themselves to be overweight/obese were three times more likely to attempt weight loss compared with those who accurately perceived themselves as being of normal weight, while the odds of attempting weight loss were the highest for those who were overweight and perceived themselves to be so (AOR∼18).
Children are likely to attempt weight loss in India irrespective of their weight status, age and gender. Children who were actually overweight as well as those who were perceived by themselves or by their parents to be overweight or obese were highly likely to try to lose weight. It is necessary to understand body weight perceptions in communities with a dual burden of being overweight and undernourished, if intervention programmes for either are to be successful.
研究减肥行为模式以及减肥尝试与实际体重状况以及儿童和家长对体重状况的认知之间的关系。
横断面研究。
印度南部卡纳塔克邦。
来自印度南部卡纳塔克邦 7 所学校的 1874 名 8-14 岁的女孩和男孩。
减肥尝试与社会人口学因素、体重状况以及儿童或父母对体重状况的认知之间的关联。
大约 73%的超重和肥胖儿童、35%的正常体重儿童和 22%的体重不足儿童试图减肥。来自社会经济地位较低群体、就读于当地语言学校的儿童和超重/肥胖儿童更有可能尝试减肥(调整后的比值比,即 ORie,95%可信区间 1.11 至 2.25;ORie,4.38,95%可信区间 2.64 至 7.28)。对体重状况的认知与减肥尝试有关。因此,体重正常但认为自己超重/肥胖的儿童,尝试减肥的可能性是准确认为自己体重正常的儿童的三倍,而超重且自我认知超重的儿童尝试减肥的可能性最高(比值比∼18)。
印度儿童无论体重状况、年龄和性别如何,都有可能尝试减肥。实际上超重的儿童以及那些自己或父母认为超重或肥胖的儿童,都非常有可能尝试减肥。如果要成功实施针对超重或营养不足的干预计划,就需要了解在同时存在超重和营养不足双重负担的社区中对体重的认知。
