Abstract

Background: Body image is known as an important factor affecting different aspects of adolescents' health; however, its relationship with lifestyle, body mass index (BMI), and health-related quality of life (HRQoL) in Iranian adolescents has not been addressed in a conceptual model.

Objectives: This study aimed to investigate the network associations among body image, lifestyle, BMI, and HRQoL in adolescent boys and girls.

Methods: The present study examined 760 adolescents (15 - 18 years) from Tehran. Adolescents reported their weight and height, according to which the participants' BMIs were calculated. The adolescents' body image, lifestyle, and HRQoL were assessed using a set of questionnaires, including the Body Image Scale for Youth (BISY), Modifiable Activity Questionnaire (MAQ), Eating Habits Checklist, Eating Attitudes Test (EAT-26), and Pediatric Quality of Life Inventory (PedsQL^TM).

Results: The participants' mean age and BMI were 16.5 ± 1.0 years and 22.4 ± 4.6 kg/m², respectively. More than one-third of boys (39.9%) and less than a quarter of girls (22.6%) were overweight/obese. In the final model, body image was significantly and directly associated with physical activity, disordered eating, eating habits, and HRQoL in both genders (P < 0.05). Moreover, body image was directly correlated with screen time in boys (P = 0.012) and BMI in girls (P = 0.001). Body image was indirectly correlated with BMI by the mediating role of disordered eating in girls. Moreover, body image was indirectly associated with HRQoL by the mediating role of physical activity and eating habits in both genders and screen time only in boys.

Conclusions: The network associations among body image, lifestyle, BMI, and HRQoL revealed a gender-specific pattern among the study population. Body image was a significant determinant of lifestyle and HRQoL in both genders and excessive weight in girls. The present findings would contribute to designing and implementing relevant health promotion interventions.

青少年身体形象、生活方式、身体质量指数与生活质量的网络关联

背景:身体形象被认为是影响青少年健康各个方面的重要因素;然而，其与伊朗青少年的生活方式、身体质量指数(BMI)和健康相关生活质量(HRQoL)的关系尚未在概念模型中得到解决。目的:探讨青少年男女身体形象、生活方式、身体质量指数与HRQoL之间的网络关系。方法:本研究调查了来自德黑兰的760名青少年(15 - 18岁)。青少年报告了他们的体重和身高，并据此计算参与者的身体质量指数。采用青少年身体形象量表(BISY)、可修改活动问卷(MAQ)、饮食习惯清单、饮食态度测试(EAT-26)和儿童生活质量量表(PedsQLTM)对青少年的身体形象、生活方式和HRQoL进行评估。结果:参与者的平均年龄为16.5±1.0岁，BMI为22.4±4.6 kg/m2。超过三分之一的男孩(39.9%)和不到四分之一的女孩(22.6%)超重/肥胖。在最后的模型中，身体形象与身体活动、饮食失调、饮食习惯和HRQoL在两性中均有显著的直接相关(P < 0.05)。男孩的身体形象与屏幕时间直接相关(P = 0.012)，女孩的身体质量指数(P = 0.001)。女孩的身体形象通过饮食失调的中介作用与BMI间接相关。此外，身体形象与HRQoL之间存在间接关联，在两性中，身体活动和饮食习惯都起到中介作用，而在男孩中，只有屏幕时间起到中介作用。结论:身体形象、生活方式、BMI和HRQoL之间的网络关联在研究人群中显示出一种性别特异性模式。身体形象是男女生活方式和HRQoL的重要决定因素，也是女孩超重的重要决定因素。本研究结果将有助于设计和实施相关的健康促进干预措施。
