To assess the differences in risk perceptions of overweight/obese and normal-weight adolescents about obesity and associated risk factors.
Qualitative study using focus group discussions (FGDs).
Five randomly selected schools from the South Indian city of Hyderabad.
Seventy-nine adolescents (ages 11-14 years) participated in 10 FGDs (5 each with overweight/obese and normal-weight groups).
Whether obesity-related risk perceptions differ with actual weight status or not.
FGDs were recorded, transcribed, and manually coded for thematic analysis. Results were presented according to 6 themes. At each stage of coding and analysis, reports were read independently by 2-3 researchers and the inter-coder reliability was high (ratio of number of agreements against the sum of agreements plus disagreements was over 90%).
Adolescents across the groups had limited understanding of nutrition during adolescence as well as causes and consequences of obesity. The optimistic bias that they were less vulnerable compared to others to the risks of obesity was evident from perceptions of overweight groups. While overweight adolescents argued that obesity was hereditary, the normal-weight participants perceived "faulty food habits" and laziness as the reasons. Adolescents across the groups considered fruits and vegetables as healthy foods.
There were clear differences in perceptions of adolescents of different weight status. Employing the risk perception analysis framework, this study identified the following adolescent traits: responsive, avoidance, and indifference, which may be useful for developing nutrition communication programs.
评估超重/肥胖青少年与正常体重青少年对肥胖及其相关风险因素的风险认知差异。
采用焦点小组讨论(FGD)的定性研究。
从印度南部城市海得拉巴随机选取的五所学校。
79名青少年(11 - 14岁)参与了10次焦点小组讨论(超重/肥胖组和正常体重组各5次)。
与肥胖相关的风险认知是否因实际体重状况而异。
焦点小组讨论进行了录音、转录,并进行手动编码以进行主题分析。结果按照6个主题呈现。在编码和分析的每个阶段,报告由2 - 3名研究人员独立阅读,编码者间信度较高(一致意见数与一致意见数加上不一致意见数之和的比率超过90%)。
各小组的青少年对青春期营养以及肥胖的成因和后果了解有限。超重组的认知表明,他们存在一种乐观偏差,即认为自己比其他人更不易受到肥胖风险的影响。超重青少年认为肥胖是遗传的,而正常体重的参与者则认为“不良饮食习惯”和懒惰是原因。各小组的青少年都认为水果和蔬菜是健康食品。
不同体重状况的青少年在认知上存在明显差异。本研究运用风险认知分析框架,确定了以下青少年特质:反应型、回避型和冷漠型,这可能有助于制定营养传播计划。
